The cabinet door lock of a chemical laboratory is a structural member which is easy to wear, and the main reason is the environment in which the door lock is needed, namely the environment around chemicals, so that the common door lock is extremely weak in the environment.
Consequently to above-mentioned condition, this application provides a lock that pure non-metallic material produced, also can satisfy the demand of current cabinet body lock.
The door lock comprises a handle portion 20 and a fixing portion 10, as shown:
the fixing portion 10 is provided with a circular convex ring 11, the circular convex ring 11 is embedded inside the cabinet door panel, and the fixing portion 10 rotates inside the cabinet door panel by taking the circular convex ring 11 as an axis. The two sides of the fixing portion 10 are provided with circular rings (as shown in fig. 4) in the figure, which can be used for positioning and installation, or can be directly and totally closed (as shown in fig. 1), and the fixing portion 10 can be installed in a door panel.
Generally, the fixing part is embedded in the door body of the cabinet body or the inner side of the door body. In use, the circular convex ring 11 is used as a rotating shaft center. The handle part 20 passes through the circular convex ring 11 from the outer side of the cabinet body door panel and then is fixed with the fixing part 10 to form a door bolt structure.
The handle part comprises a handle end 21, a first connecting column 22, a second connecting column 23, a clamping part 24 and an end part 25 which are sequentially connected.
The handle end 21 adopts a bilateral symmetry structure, and the end surface is a circular arc surface, so as to increase the hand feeling and simultaneously be used as a position indication structure of the fixing part 10 in the door lock,
the caliber of the first connecting column 22 is larger than that of the inner orifice of the circular convex ring 11; the retainer 24 has a rectangular parallelepiped structure. For better fixation, the end portion 25 is provided with a cap after extending beyond the blocking portion when the handle portion 20 and the fixation portion 10 are mated with each other.
The handle part 20 is provided with a clamping part 24 which is matched with the inner hole of the circular convex ring 11; the clamping part 24 and the inner hole of the circular convex ring 11 are inserted at a unique angle.
As a specific example, the inner hole of the circular convex ring 11 can be designed to be a cuboid or a square or other shapes as long as it is ensured that the retainer 24 can only enter the inner hole of the circular convex ring 11 at an angle.
Besides, the insertion angle is only used as a limitation, the technology can also be applied to door plates with a certain thickness, mainly when the handle part 20 is matched with the fixing part 10, the handle part 20 can be matched with the fixing part 10 only by ensuring that the clamping part 24 is positioned in the inner hole of the circular convex ring 11, so that in actual use, the depth length of the inner hole close to the circular convex ring 11 is adjusted in a left-right mode, and the door plates with different thicknesses can be installed.
The inner hole of the circular convex ring 11 is a cuboid cavity, and the handle part 20 can penetrate through the cavity. The edge of the circular convex ring 11 is provided with a blocking part; the stop portion is used to limit the protrusion distance of the handle portion 20, and the end portion 25 can protrude from the stop portion but the detent portion 24 cannot protrude.
The rectangular section of the clamping part 24 only extends into the section of the inner hole of the circular convex ring 11 at a unique angle, namely, after the general positioning is formed by the shape of the handle end 21, the clamping part 24 and the inner hole of the circular convex ring 11 are connected with each other at the unique angle by virtue of the mutual connection relationship between the clamping part 24 and the inner hole of the circular convex ring 11, and the combination mode is used for carrying out quick positioning and installation, and meanwhile, in the using process, whether the cabinet body is locked or not can be directly judged according to the shape state of the handle end 21.
Although the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the details of the foregoing embodiments, and various equivalent changes (such as number, shape, position, etc.) may be made to the technical solution of the present invention within the technical spirit of the present invention, and the equivalents are protected by the present invention.
