The present disclosure relates to a gun calibrator with an inner red dot sight.
Most modern guns are provided with a white light optical sight or red dot sight. After the sight is installed, the gun needs to be calibrated prior to using it. The fundamental method is target shooting practice, i.e., the gun is calibrated after each shooting till the correct position is reached. This method wastes time and bullets. After that, a calibration mirror for gun, a laser red dot bullet and a muzzle laser red dot rod and the like are successively developed.
Among them, a muzzle laser red dot rod, as shown in

In order to overcome the problem that the existing gun calibrators cannot be used under intense light, an auxiliary device can be employed to realize normal use thereof. The present embodiment provides a gun calibrator provided with an inner red dot sight as shown in
For convenience of use, i.e. for suiting usage habit, in the present embodiment, the inner red dot sight 3-0 is displaced on the top end of the laser module 2. In order to facilitate assembly or disassembly of the inner red dot sight 3-0, in particular a Picatinny rail 3-1 is installed or integrally manufactured at the top end of the inner red dot sight 3-0. Since the Picatinny rail is commonly used, the gun calibrator, in which the Picatinny rail is installed or into which the Picatinny rail is integrated, has good general applicability and can be used widely.
In order to suit the height of the aiming point or sight bead of different guns, the present embodiment provides a sight bracket 3-2, on the bottom of which the Picatinny rail can be clamped, to achieve assembly and disassembly of the inner red dot sight, and versatility, i.e. suiting different guns, thereby enhancing utility and universality. As shown in
To ensure a good coaxiality, the laser module 2 is further placed in the front end portion of the straight bar 1. The Picatinny rail 3-1 is correspondingly displaced on the top end of the front end portion of the straight bar 1, since the front end portion of the straight bar 1 is also used as a housing of the laser module 2.
The gun calibrator as shown in
In order to meet requirement of sufficient battery endurance of laser modules, and in order to avoid a large disturbance caused by foreign objects in the process of adjusting concentricity of the laser module 2 with the barrel, the battery cabin 3 is provided detachably from the laser module 2 in the present embodiment. As shown in
At the same time, the battery cabin 3 can be rotated around the straight bar 1 via the sleeve 6, such that after the straight bar 1 is clamped since the straight bar 1 is rotated to expand the expansion sleeve 4, the battery cabin 3 is adjusted in such a manner that the connecting line between the Picatinny rails 7 and 8 that are displaced at top end of the sleeve 6 or the bottom end of the battery cabin 3 is perpendicular to the axis of the straight bar 1, i.e. ensuring that the Picatinny rails 7 and 8 are parallel to the straight bar 1 and displaced in vertical direction. Therefore, the following problem is avoided: the Picatinny rails 7 and 8 are displaced on one side in the direction perpendicular to the axis of the straight bar 1 due to the fixation of the straight bar 1, such that the inner red dot sight is not connected to perform effective auxiliary aiming.
In order to smoothly calibrate the gun under all environments, in particular under intense light, the Picatinny rails 7 and 8 as shown in
As shown in
As can also be seen from
In order to supply power to the laser module 2 and control the operation mode, the rear end portion of the straight bar 1 is provided with a conical protruding part 13 with an increasing radius toward the battery cabin 3, as shown in
An outer circumferential edge and an inner circumferential edge of the annular conductive plate 14 are respectively provided with an outer notch 17 that facilitates bonding wire and an inner notch 18, as shown in
In order to fix the sleeve 6 and the battery cabin 3 on the straight bar 1, a clamp that may be clamped on the front end portion of the straight bar 1 is displaced at the connection of the battery cabin 3 and the sleeve 6. The clamp comprises: an inner thread connection sleeve 19 displaced on one side of the connection as shown in
As shown in
Here, the front side surface of the annular conductive plate 14 is provided with only a conductive ring 15, which completes the connection of the conductive loop together with the conductive pillar 31.
As shown in
In order to ensure that the gun calibrator will be used many times, and that there will be not an unstable state for installing the gun calibrator due to the wear of the limit device, i.e., the expansion sleeve and the annular elastic member, in particular a rubber ring, and that the cost of maintenance is reduced and it is reliable in use, the present embodiment provides an expansion sleeve as shown in
The front slip assembly 35 and the rear slip assembly 36 are connected by the connecting cylinder 37. The front slip assembly 35 is surrounded to be a cylindrical shape by at least three front slips 38, the rear end of which is connected to the connecting cylinder 37 and the front end portion of which is spherical or arc-shaped face. A gap is provided between the adjacent front gaps 38, and the outer diameter of the front slip 38 is equal to the inner diameter of the barrel.
The rear slip assembly 36 is surrounded to be a cylindrical shape by at least three rear slips 40, the front end of which is connected to the connecting cylinder 37 and the rear end portion of which is spherical or curved face, and the outer wall of each spherical or curved surface is provided with a strip-shaped block 39 that can be embedded in a rifling groove of the barrel. A gap is provided between the adjacent rear slips 40.
The connecting cylinder 37 is screwed to the rear end of a straight bar 1.
This way, when the gun calibrator is rotated to be installed into the barrel, under the guide or limit action of a block 39 that can be embedded in a rifling groove of the barrel at the rear end portion of the rear slip 40 of the rear slip assembly 36 and under the limit action of the front slip 38 having an outer diameter equal to the diameter of the barrel, it is ensured that the expansion sleeve 4 is always rotated along the barrel rifling into the barrel, while the straight bar 1 (the rear end of the straight bar 1 is a truncated cone with an increasing diameter toward the front end of the straight bar 1) is in turn rotated forward, to create an outward compressive force on the front slip assembly 35, which causes the front slip 38 of the front slip assembly 35 to expand along the radius direction of the barrel to increase the fixing force of the barrel on the straight bar 1. On the rear slip assembly 36, the diameter for the circumference where the block 39 is located is equal to or slightly greater than the diameter of the circumference where the inside rifling of the barrel is located (generally, greater than the diameter of the circumference where the inside rifling of the barrel is located by 0 to 2 mm, preferably 0.2 to 0.6 mm, or 0.4 mm, 0.8 mm, 1.2 mm, and 1.6 mm etc., depending on the strength needed by actual design). When the slip assembly 36 is loaded into the barrel rifling, the slip 40 is contracted inward after being compressed to maintain the close contact between the block 39 and the rifling groove, further ensuring the stability of the straight bar 1.
The expansion sleeve 4 is made of metal such as aluminum or steel, has good hardness, and thus can be repeatedly used without damage, thereby reducing maintenance costs and ensuring the stability and reliability of installation of the gun calibrator.
The present disclosure has the following advantage: calibration can be realized indoors or under dim light via laser by adding or integrally forming the inner red dot sight; and calibration can be realized via the inner red dot when the intensity of ambient light is greater. Further, the laser and the inner red dot can be used simultaneously to calibrate the gun, such that the laser and the inner red dot are calibrated to one another. By adding the expansion sleeve in the rear end of the straight bar, it can be realized that during spiral propulsion of the straight bar the straight bar is in better and tighter contact with the inner wall of the barrel, thereby achieving that stability is reliable, skew is difficult to occur, coaxiality is good, and adjustment accuracy is enhanced. The battery cabin is detachably displaced from the laser device, which can ensure coaxial precision, provide a power supply with larger amount of power, and allow easy replacement of battery and easy installation and debugging, without affecting the adjustment of coaxiality. By the configuration of Picatinny rail, the calibration can be performed under intense light environment via the installed optical sight such as red dot laser sight. The height adjustment of the inner red dot sight can be realized by a cushion block, such that guns having different heights of sight bead can be calibrated.
