Description

Technical Field

[0001] The utility model relates to an adjustable buckle plate structure for a lock body, belonging to the technical field of locks. Background Art

[0002] A door lock buckle plate is a structure installed inside a door frame for cooperating with a lock tongue to achieve the opening and closing actions of a door. When closing the door, after the lock tongue hits the edge of the door lock buckle plate, it first retracts and then rebounds into the door lock buckle plate to form a locking fit with the door lock buckle plate. Therefore, the cooperation between the door lock buckle plate and the lock tongue is crucial for the opening and closing of the door.

[0003] In actual production, due to the existence of processing errors, the position of the door lock buckle plate usually cannot be perfectly aligned with the lock tongue during assembly. Currently, all existing door lock buckle plates on the market are non-adjustable, and traditional door lock buckle plates have high requirements for installation accuracy. Therefore, the requirements for installers are also very high. If the installation accuracy is insufficient, it often causes the lock tongue to fail to enter the lock tongue hole of the door lock buckle plate when closing the door, resulting in the lock tongue getting stuck and unable to lock the door. Especially when the buckle plate fixing holes have been opened at the door opening, it is even more difficult to adjust, and it is easy to damage during installation or additional parts are needed for remedy. Content of the Utility Model

[0004] The utility model aims to solve the above-mentioned various problems, and further provides an adjustable buckle plate structure for a lock body. The buckle plate structure is designed simply and reasonably, and is easy to adjust, improving the assembly efficiency and ensuring the fit degree between the buckle plate and the lock tongue.

[0005] To solve the above problems, the technical solution adopted by the utility model is:

[0006] The adjustable buckle plate structure for a lock body includes a buckle box and a buckle plate pressed on the buckle box. The special feature is that through a buckle plate adjusting cam arranged between the buckle box and the buckle plate, the traditional fixed installation form of the buckle plate is changed to an adjustable installation form;

[0007] The buckle plate adjusting cam has a buckle plate fitting section adapted to the buckle plate hole and a buckle box fitting section adapted to the buckle box hole, and the buckle box fitting section and the buckle plate fitting section are eccentrically arranged with non-coaxial centers.

[0008] Further, the buckle plate hole is configured as a stepped round hole, and the buckle plate fitting section of the buckle plate adjusting cam is a stepped round platform adapted thereto.

[0009] Further, the buckle box hole is configured as a long hole, and the buckle box fitting section of the buckle plate adjusting cam is an eccentric round platform embedded in the long hole.

[0010] Further, the buckle plate adjusting cam sequentially passes through the buckle plate hole and the buckle box hole, and a gasket is riveted to the bottom thereof, thereby riveting the buckle box and the buckle plate together. On the one hand, the gasket can ensure the riveting stability of the buckle plate adjusting cam to the buckle plate and the buckle box, and on the other hand, it provides an adjustment space between the buckle plate and the buckle box.

[0011] Further, a cross groove is provided on the end face of the buckle plate adjusting cam, and the cross groove is coaxial with the buckle box matching section of the buckle plate adjusting cam.

[0012] Further, the buckle box includes a box body in the middle and ear plates at both ends, and each of the ear plates at both ends is provided with a buckle box hole; correspondingly, each of the two ends of the buckle plate is provided with a corresponding buckle plate hole.

[0013] Further, a locking structure is further provided between the buckle box and the buckle plate, and the locking structure includes a long through hole opened on the buckle plate, a screw hole opened on the buckle box, and a locking screw passing through the long through hole and locked in the screw hole.

[0014] Further, a lock tongue slot is opened on the buckle plate, and the slot width of the lock tongue slot is greater than the slot width of the middle box body of the buckle box.

[0015] The adjustable buckle plate structure for a lock body of the present invention has a simple and reasonable structural design. The left and right position adjustment of the buckle plate on the buckle box can be very conveniently realized through the buckle plate adjusting cam, so as to ensure the fit between the door lock buckle plate and the lock tongue, reduce the installation difficulty, and improve the installation efficiency.

[0021] The present invention will be described in detail below with reference to the drawings.

[0022] Embodiment 1

[0023] An adjustable buckle plate structure for a lock body, comprising a buckle box 2 and a buckle plate 1 with an assembly relationship. The buckle box 2 includes a box body 21 in the middle and connecting ears 22 at both ends of the box body 21. A lock tongue groove 11 is formed on the buckle plate 1, and the groove width of the lock tongue groove 11 is greater than the groove width of the buckle box 2. The upper and lower ends of the buckle plate 1 and the two connecting ears 22 of the buckle box 2 are assembled together through an adjusting component and a locking component.

[0024] The adjusting component is used to realize the left - right position adjustment of the buckle plate 1, and further adjust the position fit degree between the lock tongue and the lock tongue groove 11 of the buckle plate 1 when closing the door. Its structure includes buckle box long holes 22a formed on the connecting ears 22 at both ends of the buckle box 2, buckle plate round holes 1a correspondingly formed at the upper and lower ends of the buckle plate 1, and a buckle plate adjusting cam 3 riveted between the buckle box long holes 22a and the buckle plate round holes 1a. The buckle plate adjusting cam 3 has a buckle plate fitting section adapted to the buckle plate round hole 1a and a buckle box fitting section adapted to the buckle box long hole 22a. The buckle plate round hole 1a is configured as a stepped round hole in this embodiment, the buckle plate fitting section of the buckle plate adjusting cam 3 is a stepped round platform 31 adapted to it, and the buckle box fitting section of the buckle plate adjusting cam 3 is an eccentric round platform 32 embedded in the buckle box long hole 22a; the buckle plate adjusting cam 3 sequentially penetrates through the buckle plate round hole 1a and the buckle box long hole 22a from outside to inside, and a gasket 33 is spin - riveted at its bottom to rivet the buckle box 2 and the buckle plate 1 together. A cross - slot 3a is arranged on the end face of the buckle plate adjusting cam 3, and the cross - slot 3a is coaxial with the eccentric round platform 32 of the buckle plate adjusting cam 3.

[0025] The locking component is used to realize the locking connection between the buckle plate 1 and the buckle box 2; its structure includes a long through - hole 1b formed on the buckle plate 1, a screw hole 22b formed on the buckle box 2, and a locking screw 4 passing through the long through - hole 1b of the buckle plate 1 and locked in the screw hole 22b of the buckle box 2. The long through - hole 1b of the buckle plate 1 is a horizontal long through - hole.

[0026] The adjustable buckle plate structure for the lock body of the present utility model has the following adjustment and installation process:

[0027] First, loosen the locking screw 4 to loosen the buckle plate 1 from the surface of the buckle box 2 to a movable state. At this time, the buckle plate 1 is adjusted from the previous fully locked state to a state with a certain relative movement gap between it and the buckle box 2;

[0028] Then, insert a tool into the cross groove 3a on the end face of the buckle plate adjusting cam 3 and rotate the buckle plate adjusting cam 3. At this time, since the buckle box 2 is in a completely fixed state, that is, the frustum 32 of the buckle plate adjusting cam 3 is restricted within the buckle box long hole 22a of the buckle box 2, the rotation torque will be transmitted through the stepped frustum 31 of the buckle plate adjusting cam 3 to act on the buckle plate 1, and finally the buckle plate 1 can be adjusted left and right; after adjusting to the appropriate position, tighten the locking screw 4.
