Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
The convenient connection lock is used for connecting two components. The specific structure of the utility model comprises a lock catch fixing plate 1 and an elastic lock catch 2, as shown in figure 1.
Please refer to fig. 1, fig. 2, and fig. 3. The latch fixing plate 1 includes an integrally formed upper fixing plate 11 and a latch plate 12 vertically connected to one end of the upper fixing plate 11. The lower surface of the upper fixing plate 11 is provided with a first vertical limiting plate 3 and a second vertical limiting plate 4, the first limiting plate 3, the second vertical limiting plate 4 and the locking plate 12 divide the lower surface of the upper fixing plate 11 into two limiting cavities A and B, and each limiting cavity A or B is used for accommodating a component 5 or 6 to be connected, as shown in fig. 4. The locking plate 12 is provided with a positioning structure 7 with a through hole, and two sides of the positioning structure 7 are provided with insertion holes 8 which transversely penetrate through the locking plate 12.
The elastic lock catch 2 comprises an inserted rod 21, an inserted tongue 22, a spring 23, a bolt 24, a handle 25 and the like. The inserted link 21 passes through the positioning structure 7 and is fixed on the latch plate 12. One end of the inserted link 21 is provided with an inserted tongue 22. A spring 23 is sleeved on the inserted rod 21 between the inserted tongue 22 and the positioning structure 7. The inner diameter of the spring 23 is larger than the outer diameter of the positioning structure 7 and smaller than the outer diameter of the insert tongue 22, thereby ensuring that the spring is trapped between the insert tongue 22 and the positioning structure 7. The length of the inserted link 21 is longer than the distance from the lock catch plate 12 to the second limit plate 4, so that the inserted tongue 22 can reach the limit cavity a between the first limit plate 3 and the second limit plate 4 in a locked state. The distance from the inserting tongue 22 to the upper fixing plate 11 is greater than the distance from the bottom of the second limiting plate 4 to the upper fixing plate 11, so that the inserting tongue 22 is ensured not to collide with the second limiting plate 4. A handle 25 is attached to the other end of the plunger 21 and is located outside the strike plate 12. The handle 12 is provided with a bolt 24 matched with the jack 8, the bolt can be smoothly inserted into the jack 8 when the bolt is in a horizontal position, the bolt is abutted to the lock catch plate 12 through the handle, and when the bolt 24 is driven by the handle 25 to rotate and is not in the horizontal position, the end part of the bolt 24 is abutted to the lock catch plate 12. When the handle 25 is pulled to the fully contracted state of the spring, the plug tongue 22 is positioned between the second limit plate 4 and the latch plate 12, and the components positioned in the limit cavity A are ensured to move.
In order to ensure the stability of the lock of the present application, two third limiting plates 9 and 10 are provided on the locker plate 12 in parallel with the upper fixing plate 11. A reinforcing plate 91 is provided between the locking plate 12 and the third stopper plate 9 closest thereto. The bottom of the locking plate 12 is provided with a bottom plate 121 parallel to the third position-limiting plate 10, and a reinforcing plate 101 is arranged between the bottom plate 121 and the third position-limiting plate 10 closest to the bottom plate.
It should be noted that the parts 5 and 6 to be connected are provided with flush connection through holes 51 and 61. The illustrated attachment perforations 51 and 61 may be located near the upper end of the member or may be located near the upper side of the member. If the connecting hole is near the upper end and not on the side, the inserting tongue is aligned with the connecting hole 61 and then the lock of the present application is inclined when in use, the component 6 is inserted into the limiting cavity B, and then the component 5 is placed from the lower part of the limiting cavity A to be aligned with the connecting through hole 51. If the attachment holes are located laterally close to the upper end, the lock according to the invention can be directly assembled from the side with the parts 5 and 6.
The application principle is as follows:
referring to fig. 4, in an unlocking state, the handle drives the insertion rod to contract and drives the bolt to abut against the lock catch plate through rotating the handle, the insertion tongue is located in the limiting cavity B, moving or taking out of parts in the limiting cavity A is allowed, the handle does not need to be pulled all the time, and hand movement is liberated.
Referring to fig. 5, in the locked state, the handle rotates to drive the plug pin to be aligned with the jack of the handle, the plug pin is inserted into the jack under the restoring force of the spring, and the inserted link drives the inserted tongue to extend out and enter the limiting cavity B. Thereby locking the two components.
The utility model has the advantages of simple structure, convenient to use, safe and reliable, convenient to carry is fixed safely.
The above-described embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Those skilled in the art will recognize that changes and modifications can be made in the invention as described herein without departing from the scope of the invention as defined by the appended claims.
