The present invention relates to a turning holder.
At present, aimer has been widely used in the fields of firearms, bows and crossbows. Some auxiliary tools mounted on the firearm by holder are often required to be loaded when using the aimer. For example, in use of a red dot sight, a zoom lens is needed to amplify a target for a long distance and has to be dismounted for a short distance, thus the holder has to be mounted and demounted repeatedly. Besides, the operation is troublesome and inconvenient, thereby causing big inconvenience to the users.
The technical problems to be solved by the present invention is to overcome the disadvantages of the prior art and provide a turning holder which is easy to operate and convenient to use without the need for repeated mounting and demounting.
The technical scheme adopted by the present invention is: the present invention comprises a base, a holder body and a rotary body, wherein a base sleeve is provided on the base, a holder sleeve is provided on the holder body, both the base sleeve and the holder sleeve are sleeved on the rotary body and are fixedly connected with the rotary body, and the holder body can rotate relative to the base by means of the rotary body.
The rotary body comprises a shaft sleeve, a clamping sleeve for rotary shaft, a pressure ring and a locking means, wherein the clamping sleeve for rotary shaft is sleeved outside around a groove at one end of the shaft sleeve, the holder sleeve is sleeved on the shaft sleeve in a staggered position relative to the clamping sleeve for rotary shaft, the base sleeve is sleeved on and fixedly connected with the clamping sleeve for rotary shaft, and the pressure ring is sleeved on the end part of the shaft sleeve and presses the clamping sleeve for rotary shaft from outside.
The locking means comprises a rotary shaft cover, a rotary shaft, a pressure spring, a turning cap, and steel ball(s), wherein the rotary shaft cover is positioned at one end of the shaft sleeve and is fitted with the shaft sleeve, a hole which is used for the rotary shaft cover to penetrate through is formed on the rotary shaft cover, the pressure spring is arranged on the rotary shaft with one end pressing on the rotary shaft cover and the other end pressing on the rotary shaft, the turning cap is positioned at the other end of the shaft sleeve and is connected with the rotary shaft, the clamping sleeve for rotary shaft is provided with at least one limiting hole, a through hole is formed on the shaft sleeve below the limiting hole, and the steel ball(s) are restricted in the limiting hole and the through hole by the conical surface of the rotary shaft.
The base comprises a locking nut, a pressure block, a pull rod and abase body, wherein the base sleeve is provided on the base body, the pull rod penetrates through the base body and the pressure block respectively and then is in thread fit with the locking nut, and the lower part of a combination of the pressure block and the base body forms a shrinking mouth fitting with a guide rail of the firearm.
An elastic gasket and a flat steel gasket are arranged between the locking nut and the pressure block.
The holder body comprises a holder cover and a holder base fixedly connected with the holder cover, wherein the holder sleeve is provided on the holder base.
The advantageous effects of the present invention are: the present invention comprises a base, a holder body and a rotary body, a base sleeve is provided on the base, a holder sleeve is provided on the holder body, both the base sleeve and the holder sleeve are sleeved on the rotary body and are fixedly connected with the rotary body, and the holder base can rotate relative to the base by means of the rotary body; and such a structure allows users to turn the holder body flexibly according to their needs and ensures that the auxiliary tool mounted on the holder body can conveniently aim at the aimer and move away, so that the present invention is easy to operate and convenient to use without having to be mounted and demounted repeatedly.
As the rotary body comprises a shaft sleeve, a clamping sleeve for rotary shaft, a pressure ring and a locking means, the clamping sleeve for rotary shaft is sleeved outside at a groove around one end of the shaft sleeve, the holder sleeve is sleeved on the shaft sleeve in a staggered position relative to the clamping sleeve for rotary shaft, the base sleeve is sleeved on and fixedly connected with the clamping sleeve for rotary shaft, the pressure ring is sleeved on the end part of the shaft sleeve and presses the clamping sleeve for rotary shaft from outside, the locking means comprises a rotary shaft cover, a rotary shaft, a pressure spring, a turning cap, and steel ball(s), the rotary shaft cover is positioned at one end of the shaft sleeve and is fitted with the shaft sleeve, a hole which is used for the rotary shaft cover to penetrate through is formed on the rotary shaft cover, the pressure spring is arranged on the rotary shaft with one end pressing on the rotary shaft cover and the other end pressing on the rotary shaft, the turning cap is positioned at the other end of the shaft sleeve and is connected with the rotary shaft, the clamping sleeve for rotary shaft is provided with at least one limiting hole, a through hole is formed on the shaft sleeve below the limiting hole, the steel ball(s) are restricted in the limiting hole and the through hole by the conical surface of the rotary shaft, and repeated locking and unlocking can be realized by the steel ball(s); and with such a design, the structure is more compact, and the using effect is even better, so that the present invention is compact in structure and good in using effect.
As shown in
Detailed description of the invention: in an example of using the zoom lens, the base (11) is fixed on the guide rail of the firearm, the zoom lens is mounted on the holder body (12), and the turning cap (6) is pressed down to force the rotary shaft (3) to penetrate backwards through the hole (10). At this time, the steel ball (s) (7) lose the supporting force form the conical surface of the rotary shaft (3), the shaft sleeve (5) rotates relative to the clamping sleeve for rotary shaft (8), the steel ball(s) (7) move out of the limiting recesses (80), the locking effect is lost, the zoom lens on the holder body (12) is aimed at the sight vane and plays a role of amplifying, after this, the turning cap (6) is released, the rotary shaft (3) returns to its original position under the effect of a cylindrical pressure spring (4), the steel ball(s) (7) are forced back into the limiting recesses (80) again by the conical surface of the rotary shaft (3), and the steel ball(s) (7) will lock the clamping sleeve for rotary shaft (8) and the shaft sleeve (5) again.
The present invention can be widely applied to the field of the firearm and bow and crossbow.
