Description
Technical Field
[0001] The utility model relates to the technical field of door lock boxes, in particular to a self-adjusting lock box. Background Art
[0002] In the current lock technology field, magnetic locks are widely used as security devices. Their basic working principle relies on the attraction between opposite poles of magnets to ensure the matching connection between the lock tongue and the lock box, thereby achieving effective closure of the door panel and door frame and ensuring safety. In this type of lock design, the magnetic attraction component usually includes a magnetic lock tongue installed inside the lock core and a lock box fixed on the door frame. When the two are close together, they are automatically aligned and locked due to magnetic attraction, providing users with a convenient opening and closing experience.
[0003] However, in actual applications, especially when installing this type of magnetic lock for the first time, the problem of assembly gap between the lock tongue and the lock box is often encountered. Due to the unevenness of the door frame material or the limitation of installation accuracy, a gap may appear between the lock tongue and the lock box due to installation deviation. The existence of these gaps not only affects the sealing performance of the door, reduces the sound insulation and heat insulation effects, but also may cause the door to shake unnecessary when closed, thereby generating a certain amount of noise. For the gap problem during installation, a common solution in the prior art is to manually eliminate the gap by adjusting the fixing screws inside the lock box and artificially changing the installation position of the lock box. However, this method is complicated to operate, and the entire adjustment process often involves partial disassembly and reinstallation of the lock, which is time-consuming and laborious. Moreover, this process is particularly inconvenient for non-professionals. No effective solution has been proposed for the problems in the relevant technology. Utility Model Content
[0004] In view of the problems in the related art, the utility model proposes a self-adjusting lock box to overcome the above technical problems existing in the existing related art.
[0005] To this end, the specific technical solutions adopted by the utility model are as follows:
[0006] A self-adjusting lock box comprises a lock box seat, a surface of the lock box seat is provided with an adjustment groove on one side, a lock box body is slidably mounted inside the adjustment groove, a surface of the lock box body is provided with a tongue groove, inner walls of the tongue groove are provided with clamping inclined planes on both sides, one side of the surface of the lock box body is fixedly connected with an adjustment inclined plane 1, and the other side is fixedly connected with an adjustment inclined plane 2, the thickness of the adjustment inclined plane 1 is greater than that of the adjustment inclined plane 2, a bottom surface of the lock box seat is provided with a magnetic suction groove 1 on one side, a first magnet is fixedly mounted inside the magnetic suction groove 1, a magnetic suction groove 2 is provided inside the lock box body, a second magnet is fixedly mounted inside the magnetic suction groove 2.
[0007] Furthermore, in order to achieve the matching connection between one end of the lock core and the lock box, a lock core is provided on one side of the lock box seat, and a lock tongue is slidably installed at one end of the lock core, and the lock tongue is slidably installed in the tongue groove.
[0008] Furthermore, in order to facilitate the removal of the lock box body from the adjustment slot, a disassembly frame is fixedly connected to the surface edge of the lock box body.
[0009] Furthermore, in order to facilitate the fixed installation of the lock box seat on the door frame, fixing grooves are opened on both sides of the surface of the lock box seat, a positioning plate is fixedly connected to one side of the inner side of the fixing groove, and a positioning bolt is threadedly connected to the surface of the positioning plate.
[0010] Furthermore, in order to increase the structural strength in the locking seat, reinforcing ribs are fixedly connected to both sides of the fixing groove, and an arc-shaped support plate is fixedly connected to one side of the reinforcing rib.
[0011] Furthermore, in order to prevent the lock box body from easily falling off from the adjustment groove, anti-skid rubber pads are fixedly installed on both sides of the inner wall of the adjustment groove.
[0012] Furthermore, in order to achieve a clamping effect on the lock tongue by the clamping inclined surfaces on both sides of the inner wall of the tongue groove, the distance between the clamping inclined surfaces on both sides of the inner wall of the tongue groove is smaller than the width of the end of the lock tongue.
[0013] The beneficial effects of the utility model are:
[0014] 1. Through the clamping inclined surfaces on both sides of the inner wall of the tongue groove, when the lock tongue is slid and installed into the inner wall of the tongue groove under the magnetic attraction force, even if there is a gap between the lock tongue and the inner wall of the tongue groove when the door lock is installed, the gap between the two can be reduced and eliminated by the lock tongue gradually approaching the end of the clamping inclined surface after entering the tongue groove. There is no need to disassemble and reinstall the lock box to adjust the gap, saving time and effort.
[0015] 2. When the deviation of the lock core position after installation is greater than the thickness of the clamping bevel in the tongue groove, the lock tongue can only be partially inserted into the tongue groove, and there is still a gap with the clamping bevel on one side. The lock box body adsorbed in the adjustment groove can be taken out from the adjustment groove, and then the positions of the adjustment bevels 1 and 2 are swapped and reinstalled into the adjustment groove. Since the thicknesses of the adjustment bevels 1 and 2 are different, the position of the tongue groove is changed, so that the lock tongue can continue to be adsorbed and slide into the tongue groove, thereby eliminating the gap between the lock tongue and the tongue groove. The lock box can be adjusted without disassembling the lock box, and the operation is convenient and quick.
[0016] 3. Through the clamping bevels on both sides of the inner wall of the tongue groove, and the distance between the two clamping bevels is smaller than the width of the end of the lock tongue, when the lock tongue is slidably installed inside the tongue groove by the magnetic attraction inside the lock box body, the lock tongue is limited by the two clamping bevels, and the end will not collide with the bottom of the tongue groove, thereby effectively reducing the noise when closing the door.
