The disclosure relates to a connector for fixing a laminate between two vertical plates.
Conventional connectors include a connecting rod and an expansion sleeve sleeving the connecting rod, for the connection of side plates (vertical plates) and laminates (horizontal plates). During installation, one end of the expansion connector is first inserted into a laminate, and then the laminate is approached perpendicularly to a side plate so that the other end of the expansion connector is installed into the side plate, thus achieving the connection of the laminate and the side plate. The connector cannot be used to fix a laminate between two vertical plates, and the connection between a laminate and a vertical plate with the connector is not firm.
One objective of the disclosure is to provide a connector for fixing a laminate between two vertical plates, and the installation process is easy to operate with high firmness.
The disclosure provides a connector for fixing a laminate between two vertical plates, comprising: a sleeve, a connecting rod, an embedded part, a rear cover, and a compression spring. The sleeve is hollow and comprises two open ends; an inner wall of the sleeve comprises a limit step; the connecting rod is disposed in the sleeve and comprises a first end and a second end; the first end comprises a stop part matched with the limit step; the second end extends out of the sleeve; the rear cover is detachably disposed on a rear end of the sleeve; the compression spring is disposed in the sleeve and comprises a third end abutting against the rear cover and a fourth end abutting against the stop part; and the embedded part comprises an embedded nut and a fastener; the fastener is detachably disposed in the embedded nut and is connected to the second end of the connecting rod.
In a class of this embodiment, the rear end of the sleeve comprises a hole, and the rear cover comprises a buckle matched with the hole.
In a class of this embodiment, the sleeve comprises a front end surface comprising a first unidirectional reverse thread.
In a class of this embodiment, the fastener comprises a blind nut and a locking nut; the locking nut is disposed in the blind nut; and the blind nut is detachably disposed in the embedded nut.
In a class of this embodiment, the embedded nut comprises a limiting buckle for limiting the blind nut so that the bind nut is stably located in the embedded nut.
In a class of this embodiment, an outer surface of the embedded nut comprises a second unidirectional reverse thread.
In a class of this embodiment, a convex bar is disposed on the inner wall of the sleeve between the rear cover and the limit step; the stop part comprises a groove; and the convex bar is matched with the groove to guide the connecting rod to move axially.
The following advantages are associated with the connector for fixing a laminate between two vertical plates of the disclosure: the combination of the sleeve, the connecting rod, and the embedded part of the connector allows for the connection of a laminate (horizontal plate) with two vertical side plates; the installation is convenient and firm, and is a hidden connection.
To further illustrate the disclosure, embodiments detailing a connector for fixing a laminate between two vertical plates are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.
As shown in
The rear end of the sleeve 1 comprises a hole 12, and the rear cover 4 comprises a buckle 41 matched with the hole 12, thus facilitating the detachment of the rear cover from the sleeve. The sleeve 1 comprises a front end surface comprising a first unidirectional reverse thread 13. In the mounting process, the first unidirectional reverse thread 13 is smoothly screwed into a laminate without obstruction; to pull out the sleeve, the friction between the first unidirectional reverse thread and the laminate requires to be overcome, which is difficult, thus improving the stability of the installation of the laminate.
The fastener 32 comprises a blind nut 321 and a locking nut 322; the locking nut 322 is disposed in the blind nut 321. The internal structure of the blind nut 321 is designed to match the external shape of the locking nut 322, which can be a hexagonal nut or other types of nuts. The external structure of the blind nut 321 is cylindrical, with one end open and the other end closed. The center of the closed end comprises a cross hole that can be inserted with a tool such as an electric screwdriver to twist the embedded part to lock the side plate of the laminate. The cross hole can be replaced by a straight hole, or a hexagonal hole. The blind nut 321 is detachably disposed in the embedded nut 31. One end of the embedded nut 31 is open, and the other end is provided with a limiting buckle 311 for limiting the blind nut so that the bind nut is stably located in the embedded nut. The center part of the blind nut 321 is a counter bore (countersunk hole). The outer surface of the embedded nut 31 comprises a second unidirectional reverse thread 312, which has the same function as the first unidirectional reverse thread. Specifically, the first unidirectional reverse thread 13 is disposed on the front surface of the sleeve 1. When the sleeve 1 enters a mounting hole position, as shown in
Optionally, both ends of the embedded nut 31 are open, and the limit mechanisms are disposed at the openings to limit the blind nut 321 to rotate within the cavity of the embedded nut 31. The opening of one end of the embedded nut 31 receives the extension end of the connecting rod 2, and the limit mechanism 311′ is disposed circumferentially or symmetrically on the open end. The limiting buckle 311 is symmetrically or circumferentially disposed at the other end of the embedded nut 31, and is a unidirectional chamfered structure used for the blind nut 321 to slide unidirectionally into the cavity of the embedded nut 31 along the limit buckle 311.
When installing, first, first holes 610 are respectively preset in a first laminate 61 and a second laminate. The embedded part is placed in the hole of the first laminate, and the sleeve 1 and the connecting rod 2 are disposed in the second hole 620 of the second laminate 62. Combine the first laminate and the second laminate, and the threaded end of the connecting rod 2 is inserted in the embedded part 3. Turn the embedded part 3 by an electric screwdriver through a blind hole 611 to lock the connecting rod 2, thus achieving the installation of the first laminate and the second laminate.
Optionally, the embedded part 3 can also be installed in the side plate, and the sleeve 1 and connecting rod 2 can be correspondingly installed in the horizontal plate.
The combination of the sleeve 1, the connecting rod 2, and the embedded part 3 of the connector allows for the connection of a laminate (horizontal plate) with two vertical side plates; the installation is convenient and firm, and is a hidden connection.
It will be obvious to those skilled in the art that changes and modifications may be made, and therefore, the aim in the appended claims is to cover all such changes and modifications.
