Description

Technical Field

[0001] This utility model relates to the field of smart lock accessory design, and in particular to an adjustable door frame box for a smart lock. Background Technology

[0002] A smart lock is a type of lock that can be unlocked not only with a key, but also through light, electricity, magnetism, sound, or fingerprint. When a smart lock is to be used on a door, in addition to the smart lock body being mounted on the door, a groove is usually made in the door frame, and then a door frame box is installed in the groove to allow the lock tongue of the smart lock body to effectively extend into the door frame box to lock.

[0003] Currently, the door frame box of common smart locks, once fixed in the groove, often cannot be effectively adjusted in position. However, in actual installation and use, it has been found that due to certain installation errors in the smart lock body and the door or the door frame box on the door frame, or after the door has been used for a long time, the relative position between the door and the door frame may shift. Sometimes, the bolt on the smart lock body cannot effectively extend into the door frame box, making it impossible to open and close the door normally. In this case, adjusting the position of the door frame box to match the use of the bolt is very difficult, time-consuming and laborious. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable door frame box for a smart lock, which can solve one or more of the above-mentioned problems.

[0005] According to one aspect of this utility model, an adjustable door frame box for a smart lock is provided, including an outer door frame box, an inner door frame box, and fixing screws.

[0006] The outer casing of the door frame is provided with a groove, and the groove contains a first toothed section and a screw hole.

[0007] The inner box of the door frame is provided with a second toothed segment on its outer periphery, and the inner box of the door frame is disposed on a groove, wherein the first toothed segment and the second toothed segment mesh with each other.

[0008] The inner box of the door frame is provided with a receiving cavity, and the receiving cavity is provided with a strip-shaped hole. The fixing screw can pass through the strip-shaped hole and be connected to the screw hole.

[0009] The beneficial effects of this utility model are as follows: The accommodating cavity can accommodate the lock tongue of the smart lock. Before fixing with screws, the user can change the position of the inner box of the door frame by altering the meshing position of the first and second tooth segments, thus effectively matching the position of the accommodating cavity with the lock tongue. The inner box of the door frame is highly adjustable, avoiding problems caused by errors in installation or use that prevent the utility model and the lock tongue from effectively cooperating after installation. Even if the position of the inner box of the door frame needs to be changed to match the lock tongue later, there is no need to adjust the position of the outer box of the door frame. After the inner box of the door frame is adjusted, it can be fixed with screws. At this time, the meshing of the first and second tooth segments also plays a certain limiting role, effectively preventing changes in the position of the inner box of the door frame, thereby ensuring that the position of the inner box of the door frame is effectively maintained after installation.

[0010] In some embodiments, the present invention further includes a door strike plate connected to the outer box of the door frame, the door strike plate shielding the first and second tooth segments. The door strike plate can hide and protect the first and second tooth segments.

[0011] In some embodiments, the outer casing of the door frame is provided with an extension plate, the extension plate having a plurality of first holes, and the door latch plate having a plurality of second holes, with the plurality of first holes and the plurality of second holes being connected in a one-to-one correspondence. By connecting the corresponding first holes and second holes, the extension plate and the door latch plate can be effectively fixed.

[0012] In some embodiments, the fixing screw has a screw head that presses against the inner box of the door frame. The screw head pressing against the inner box ensures that the fixing screw can effectively secure the inner box to the outer box of the door frame.

[0013] In some embodiments, a recess is provided around the periphery of the strip-shaped hole, and the screw head can abut against the recess. By providing the recess, the contact area between the screw head and the inner box of the door frame can be increased, thereby improving the reliability of the fixing screw to the inner box of the door frame.

[0014] In some embodiments, the strip-shaped hole and the screw hole are connected, and the length and width of the strip-shaped hole are not less than the diameter of the screw hole. This ensures that the strip-shaped hole and the screw hole remain connected after the inner box of the door frame has moved and its position has been adjusted, thus facilitating the installation of the fixing screws.

[0015] In some implementations, the length of the first tooth segment is greater than the length of the second tooth segment. This ensures that after the inner box of the door frame has finished moving, i.e., after the position adjustment, the second tooth segment can still mesh with the first tooth segment.

[0016] In some embodiments, the width of the groove is not less than the width of the inner box of the door frame, and the length of the groove is not less than the length of the inner box of the door frame. This allows the groove to provide sufficient space for the inner box of the door frame to move. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] refer to Figures 1-4 The present invention relates to an adjustable door frame box for a smart lock, comprising an outer door frame box 1, an inner door frame box 2, and fixing screws 3.

[0024] The outer box 1 of the door frame is provided with a groove 11. The top and bottom of the groove 11 are respectively provided with a first tooth segment 111. The first tooth segment 111 can be formed by multiple teeth arranged side by side. The side of the groove 11 is provided with a screw hole 112. The screw hole 112 can preferably be a columnar screw hole.

[0025] The top and bottom of the outer perimeter of the inner box 2 of the door frame are respectively provided with a second tooth segment 21. The second tooth segment 21 can also be composed of multiple teeth arranged side by side. The size of the teeth of the first tooth segment 111 and the second tooth segment 21 is similar, but the number of teeth of the first tooth segment 111 is more than the number of teeth of the second tooth segment 21, so that the length of the first tooth segment 111 is greater than the length of the second tooth segment 21.

[0026] Furthermore, the width of the groove 11 is not less than the width of the inner box 2 of the door frame, the length of the groove 11 is not less than the length of the inner box 2 of the door frame, and the depth of the groove 11 is equivalent to the thickness of the inner box 2 of the door frame, so that the inner box 2 of the door frame can be movably disposed on the groove 11, and the second tooth segment 21 on the top of the inner box 2 of the door frame can mesh with the first tooth segment 111 on the top of the groove 11. At the same time, the second tooth segment 21 on the bottom of the inner box 2 of the door frame can mesh with the first tooth segment 111 on the bottom of the groove 11.

[0027] The inner box 2 of the door frame is provided with a receiving cavity 22, which can match the size of the smart lock tongue that needs to be accommodated, so that the receiving cavity 22 can effectively accommodate the smart lock tongue.

[0028] The accommodating cavity 22 is provided with a strip-shaped hole 221. When the inner box 2 of the door frame is placed in the groove 11, the strip-shaped hole 221 and the screw hole 112 are opposite to each other and connected. The length and width of the strip-shaped hole 221 are not less than the diameter of the screw hole 112, so that after the inner box 2 of the door frame moves in the groove 11, the strip-shaped hole 221 can still maintain the connection with the screw hole 112.

[0029] The fixing screw 3 can pass through the strip hole 221 and be connected to the screw hole 112 by thread engagement. The strip hole 221 has a recess 222 on its periphery, and the fixing screw 3 also has a screw head 31. The screw head 31 can abut against the recess 222, that is, the screw head 31 can press against the inner box 2 of the door frame, so that the fixing screw 3 fixes the outer box 1 of the door frame and the inner box 2 of the door frame.

[0030] The adjustable door frame box of this smart lock also includes a door strike plate 4, which is fixedly connected to the outer door frame box 1 by screws. Specifically, the outer door frame box 1 is provided with an extension plate 12, which is provided with a plurality of first holes 121, and the door strike plate 4 is provided with a plurality of second holes 41. The plurality of first holes 121 and the plurality of second holes 41 are connected one-to-one, and the corresponding first holes 121 and second holes 41 can be connected by screws, so that the door strike plate 4 is fixedly connected to the outer door frame box 1. After installation, the door strike plate 4 will press on the inner door frame box 2 and block the first tooth segment 111 and the second tooth segment 21.

[0031] This smart lock's adjustable door frame box can be used in conjunction with the smart lock body installed on the door. During installation, a groove can be provided on the door frame, and the outer door frame box 1 can be embedded in the groove, with the extension plate 12 of the outer door frame box 1 located outside the groove. Then, the user can adjust the position of the inner door frame box 2 within the outer door frame box 1 according to the position of the lock tongue of the smart lock body, so that when the door is locked, the lock tongue can effectively extend into the receiving cavity 22 of the inner door frame box 2.

[0032] After the position of the inner box 2 of the door frame is adjusted, the first tooth segment 111 and the second tooth segment 21 can mesh with each other. At the same time, the strip hole 221 can still maintain communication with the screw hole 112. Then, one end of the fixing screw 3 is passed through the strip hole 221 and connected to the screw hole 112 through thread engagement until the screw head 31 can abut against the recess 222. At this time, the fixing screw 3 can fully fix the inner box 2 of the door frame to the outer box 1 of the door frame.

[0033] Then, screws can be used to connect the corresponding first hole 121 and second hole 41, and the screws are also connected to the door frame to install the door strike plate 4, so that the adjustable door frame box of the smart lock is fully fixed on the door frame. At this time, the door strike plate 4 is effectively pressed on the outer box 1 of the door frame and can block the first tooth segment 111 and the second tooth segment 21.

[0034] In addition, even if the relative position between the door and the door frame shifts due to prolonged use and the position of the door frame inner box 2 needs to be adjusted to match the lock tongue position, the door frame inner box 2 can be adjusted simply by removing the door strike plate 4 and the fixing screws, without adjusting the door frame or removing the door frame outer box 1. This operation is convenient, time-saving and labor-saving.

[0035] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
