[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A concealed lock cylinder hole decorative cover for a door lock, comprising:

[0027] The main body includes a cover plate 1, a base 12 is fixed to the lower surface of the cover plate 1, and a screw 11 is movably connected to the upper surface of the cover plate 1. The cover plate 1 is threadedly fixed to the upper surface of the base 12 by the screw 11. Multiple grooves are opened on both sides of the base 12 for installation.

[0028] The active mechanism includes a first cover plate 2, which is movably connected to the upper surface of the cover plate 1. A buckle 22 is movably connected inside the first cover plate 2, and a tension rope 21 is fixedly connected to the lower end of the buckle 22. A rope storage box 23 is movably connected to the lower surface of the base 12. The tension rope 21 is movably connected inside the rope storage box 23. The tension rope 21 is elastic and can drive the first cover plate 2 to move within a certain range. The buckle 22 provides convenience for replacement and installation when the internal groove of the first cover plate 2 is used.

[0029] The storage mechanism includes a clamping plate 3, which is fixedly connected to the lower surface of the base 12. A spring 33 is fixedly connected inside the clamping plate 3. A pressure plate 32 is fixedly connected to the end of the spring 33 away from the clamping plate 3. A second cover plate 31 is movably connected inside the clamping plate 3. A circular through groove is opened on the upper surface of the clamping plate 3 at the position of the first cover plate 2. When using the first cover plate 2, the first cover plate 2 can be removed by simply pressing down.

[0030] Furthermore, the screw 11 has threads on its surface, and the cover plate 1 is threaded to the base 12 through the screw 11. The screw 11 penetrates the cover plate 1 and connects to the base 12. A cross-shaped groove is provided on the upper surface of the screw 11 to facilitate installation and use.

[0031] Furthermore, the cover plate 1 is a cuboid, and two sets of screws 11 are provided on the surface of the cover plate 1, with two screws in each set, which strengthens the stability of the cover plate 1 fixed on the surface of the base 12. The cover plate 1 is the same color as the first cover plate 2, which increases the aesthetics and concealment of the first cover plate 2.

[0032] Furthermore, the first cover plate 2 is elliptical, and the surface of the cover plate 1 has a through groove with the same shape as the first cover plate 2, which increases the concealment of the first cover plate 2. The first cover plate 2 can be divided into two parts: the upper part of the first cover plate 2 is elliptical and the lower part is rectangular. The upper surface of the base 12 has a rectangular groove of the same shape, so that the lower part of the first cover plate 2 can be inserted into the groove on the surface of the base 12, which enhances the stability of the first cover plate 2.

[0033] Furthermore, the buckle 22 is fixedly connected to the tension rope 21 in a "T" shape. The first cover plate 2 is movably connected to the tension rope 21 through the buckle 22. The rope storage box 23 is movably connected to the side of the clamp plate 3 near the base 12. Replacing the buckle 22 is simple and convenient. Just insert the buckle 22 into the groove inside the first cover plate 2, which solves the problem of the decorative cover being inconvenient to install and replace.

[0034] Furthermore, the clamping plate 3 is a cuboid with a groove inside. The second cover 31 is the same size and shape as the first cover 2. The groove inside the clamping plate 3 saves space. When the first cover 2 is lost or damaged, it can be replaced by the second cover 31, making it more convenient to use.

[0035] Furthermore, the spring 33 is fixed in the groove inside the clamping plate 3, and the pressure plate 32 is elastically connected to the clamping plate 3 through the spring 33. The second cover plate 31 is engaged and connected inside the clamping plate 3 through the pressure plate 32. The pressure plate 32 plays a protective role for the second cover plate 31. There are two sets of springs 33 and pressure plates 32, which are symmetrical in the groove inside the clamping plate 3, so that the force is more even and the stability of the second cover plate 31 in the clamping plate 3 is enhanced.

[0036] Working principle: When using the concealed lock cylinder hole decorative cover, first take out the tension rope 21 and buckle 22 from the rope storage box 23, and install the buckle 22 in the groove inside the first cover plate 2. The buckle 22 and tension rope 21 are fixedly connected. After installation, the first cover plate 2 can be stretched to check whether the buckle 22 is secure. The first cover plate 2 coincides with the groove on the surface of the cover plate 1, which solves the problem that the decorative cover is not concealed enough and is inconvenient to install and replace. When you want to unlock, you can press down on the upper end of the first cover plate 2. The base 12 and the clamping plate 3 have through slots at the corresponding positions on the upper end of the first cover plate 2. The base 12 will tilt upwards, and the first cover plate 2 can be easily removed. When the first cover plate 2 is lost or damaged, the second cover plate 31 can be removed from the groove inside the clamping plate 3 for replacement.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
