Technical Field

[0001] The present application relates to the technical field of locks, and in particular to a lock installation structure. Background Art

[0002] There are many components installed in the shell of the smart lock. In order to facilitate the replacement and maintenance of the components, the shell adopts a structure that is easy to open and close.

[0003] For example, a Chinese patent with publication number CN215717847U discloses a lock installation structure and a smart lock, including a stacked mounting plate and a back plate, wherein a buckle and a protrusion are fixedly provided on the mounting plate, and the back plate is provided with a snap-on portion and an elastic locking portion corresponding to the buckle and the protrusion, respectively. By driving the back plate to move relative to the mounting plate, the snap-on portion can be driven toward or away from the snap-on connection, and the elastic locking portion can limit the movement of the protrusion to maintain the snap-on connection with the snap-on portion.

[0004] However, when the above structure is adopted, the installation and disassembly of the lock require manual removal of the limit screws, and the installation and disassembly process is relatively complicated and difficult to operate. Utility Model Content

[0005] The utility model aims to provide a lock installation structure, which is convenient for installation and disassembly of the lock and prevents the lock from falling off after installation.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A lock installation structure includes a lock body and a cover plate engaged with the lock body, wherein the lock body is provided with a buckle, and the cover plate is provided with a clamping portion, the clamping portion is elastically connected to the cover plate, and the clamping portion is provided with a clamping slot corresponding to the buckle. By driving the clamping portion to move relative to the cover plate, the clamping portion can be driven to move toward or away from the clamping connection with the buckle.

[0008] Preferably, the clamping portion is provided with a first tension spring accommodating portion for accommodating the head end of the tension spring, and the cover plate is correspondingly provided with a second tension spring accommodating portion for accommodating the tail end of the tension spring.

[0009] Preferably, the first tension spring accommodating portion and the second tension spring accommodating portion are hollow cylindrical bodies.

[0010] Preferably, the clamping portion includes a first clamping portion and a second clamping portion, the bayonet is arranged on the first clamping portion, the first tension spring accommodating portion is arranged on the second clamping portion, and the first clamping portion is fixed to the second clamping portion by screws.

[0011] Preferably, the cover plate is provided with an opening corresponding to the snap-in opening of the snap-in portion, and the cover plate is provided with a groove body for engaging with the snap-in portion.

[0012] Preferably, a limit block for snap-on limiting is provided on the upper side of the opening.

[0013] Preferably, the cover plate is provided with a through hole, and the through hole can accommodate a screw or a bolt.

[0014] Preferably, a screw slider is arranged outside the through hole.

[0015] Preferably, an anti-slip strip is provided on a side of the cover plate away from the lock body, and the anti-slip strip is arranged on the left and right sides of the cover plate.

[0016] The beneficial effects of the utility model are as follows: the clamping part of the application is elastically connected to the cover plate, and the clamping part can be driven to move toward or away from the clamping connection with the buckle only by driving the clamping part to move relative to the cover plate, so that the lock body can be quickly installed and disassembled, and the application directly uses part of the cover plate body as a limit block, without the need to use screws to limit from the outside, so the installation and disassembly of the cover plate is simpler and more convenient; and after installation, due to the spring force and the two-way force of the buckle, the installation is stable, and the lock body of the buckle is not easy to loosen and fall off during vibration.

DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] As Figure 1-3 shown, a lock installation structure, in this Embodiment 1, includes a lock body 1 and a cover plate 2 that engages with the lock body. In specific applications, as Figure 1 shown, screws pass through the through holes 12 to install the cover plate 2 on the door panel, and the lock body 1 engages with the cover plate 2; a buckle 3 is provided on the lock body 1, and a clamping portion 4 is provided on the cover plate 2. The clamping portion 4 is elastically connected to the cover plate 2. Among them, the clamping portion 4 is provided with a first tension spring receiving portion 6 for receiving the head end of the tension spring 5, and the cover plate 2 is correspondingly provided with a second tension spring receiving portion 7 for receiving the tail end of the tension spring 5; in order to make the installation of the tension spring 5 more stable, the first tension spring receiving portion 6 and the second tension spring receiving portion 7 are hollow cylindrical bodies.

[0027] The clamping portion 4 is provided with a bayonet 8 corresponding to the buckle 3 for clamping. An opening 9 corresponding to the bayonet 8 of the clamping portion 4 is provided on the cover plate 2. After the buckle 3 passes through the opening 9, it engages with the bayonet 8. By driving the clamping portion 4 to move relative to the cover plate 2, it is possible to drive the clamping portion 4 to approach or disengage from the buckle 3.

[0028] In a specific embodiment, in order to make the cover plate 2 and the clamping portion 4 match the shape of the lock body 1, the cover plate 2 is provided with a groove 10 for fitting with the clamping portion 4. After the clamping portion 4 is fitted with the cover plate 2, the overall shape is the same as that of the lock body 1, and the thickness of the fitting portion is the same as the thickness of the cover plate 2, which is more beautiful and practical.

[0029] In a specific embodiment, two buckles 3 are symmetrically provided on each of the upper and lower sides of the lock body 1. Correspondingly, clamping portions 4 are provided on both the upper and lower sides of the cover plate 2. Each clamping portion 4 is provided with two bayonets 8, and the bayonets 8 are in the shape of a "mouth"; the groove 10 provided on the cover plate 2 is used to accommodate both sides of the "mouth"-shaped bayonet. When the clamping portion 4 elastically moves up and down relative to the cover plate 2, the size of the bayonet 8 also changes accordingly, so as to realize the clamping or disengagement of the clamping portion 4 and the buckle 3.

[0030] Since the position of the opening 9 of the cover plate 2 corresponds to the bayonet 8 of the clamping portion 4, correspondingly, the position of the groove 10 of the cover plate 2 is opened on the upper side of the opening 9, and the middle area between the two grooves 10 protrudes relative to the groove. This part can be used as a limiting block 11 for the buckle 3 to prevent the buckle 3 from moving further upward and disengaging from the clamping.

[0031] The cover plate 2 is provided with a through hole 12 that can accommodate screws or bolts. In a specific embodiment, by providing a screw slider 13 at the through hole 12, smaller-sized screws or bolts can be used.

[0032] In a specific embodiment, an anti-slip strip 14 is provided on one side of the cover plate 2 close to the door panel to make it more stable after installation.

[0033] Example 2

[0034] On the basis of Example 1, Figure 4-6 A lock installation structure is shown. In this embodiment 2, the clamping part 4 includes a first clamping part 41 and a second clamping part 42, the bayonet 8 is arranged on the first clamping part 41, and the first tension spring accommodating part 6 is arranged on the second clamping part 42, and the first clamping part 41 and the second clamping part 42 are fixed by screws; because the bayonet 8 and the first tension spring accommodating part 6 are relatively fragile parts, in this embodiment 2, the bayonet 8 and the first tension spring accommodating part 6 are separately arranged on the first clamping part 41 and the second clamping part 42. Then, when some parts are damaged, it is only necessary to replace the first clamping part 41 or the second clamping part 42 accordingly, and there is no need to replace the clamping part as a whole, thereby saving resources.

[0035] The other structural settings of this embodiment 2 are the same as those of embodiment 1.

[0036] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
