Problems solved by technology

[0004] 1. The equipment locking device will cause irreversible damage to the floor during installation. People usually fix the equipment on the floor by drilling holes in the floor and fixing it with nuts. In this way, once the fixed equipment is moved to other places in the future, it will inevitably Leave holes, scratches and other damage in the original position;
[0005] 2. Due to the limitation of its own fixing method, it takes a lot of time and manpower to install or remove the device locking device, and it will consume a lot of resources just for installation and removal;
[0006] 3. In the clean room, the installation or disassembly of the locking device requires skilled engineers to operate, which also causes inconvenience in use
[0007] The various problems of the above-mentioned locking device may be reflected in different industries, especially in industries that use clean rooms in the manufacturing process. These problems are particularly prominent because the floors of clean rooms are expensive. If the ground is damaged due to the installation and fixation of the equipment, it will be a very large waste

Embodiment 1

[0037] The specific structure of the instant opening and closing device locking device

[0038] This embodiment provides a specific example of a locking device for an instant opening and closing device, which includes the following main components: a hook 1 , a sleeve 2 , a positioning nut 3 and a right-angle plate 4 .

[0039] Figure 1a and Figure 1b are the front view and the top view of the hook 1 respectively, the number 11 in Figure 1a represents the hook tip outer slope of the hook, and the number 12 is the place where the hook is connected by the pin and the sleeve, that is, the pin hole;

[0040] Fig. 2 a and Fig. 2 b are the front view and the top view of sleeve 2 respectively, and the number 21 in Fig. 2 a represents the groove on the sleeve, and the number 22 represents the nut hole that is compatible with positioning nut 3;

[0041] Fig. 3 is the front view of positioning nut 3, and positioning nut has the screw thread that accords with hole 22;

[0042] Figures 4...

Embodiment 2

[0047] The use process of the instant opening and closing device locking device

[0048]When it is necessary to fix the equipment in the clean room, such as a cart with wheels, the locking device provided in Embodiment 1 is used. The size and length of the sleeve and the hook of the locking device have been designed to be consistent with the floor of the clean room. Existing holes are suitable, and the axle of cart can be used as screw 7 shown in Figure 5.

[0049] Firstly, the locking device of Embodiment 1 is sleeved on the wheel shaft through the right-angle plate 4, that is, on the screw 7, and then the sleeve 2 of the locking device is inserted vertically downward into the hole on the floor of the clean room, because the sleeve 2 The outside of the hook tip of the hook 1 is a slope structure 11. During the insertion process, the part of the hook exposed outside the slot 21 of the sleeve 2 is affected by the force of the slope 11, and retracts into the sleeve 2 until the s...

Embodiment 3

[0052] Another design scheme of the equipment locking device of the present invention

[0053] Please refer to the front view of the locking device in the combined state shown in Figure 8, each component of the locking device provided in this embodiment can refer to the solution of embodiment 1, the difference with respect to embodiment 1 is that the positioning nut 3. Instead of controlling the entry and exit through the threads of the hole 22 of the sleeve 2, but by setting a return spring between the positioning nut 3 and the sleeve 2, the entry and exit of the positioning nut 3 is controlled by pressing and spring reset; correspondingly , the protruding direction of the hook tip of the hook 1 should also be adjusted to the opposite of that of Example 1.

[0054] When using this locking device to fix the equipment, insert the sleeve 2 into the corresponding hole. Due to the action of the inclined surface structure 11 outside the hook tip, the hook 1 rotates around the pin a...

Abstract

The invention provides an equipment lock device, especially for cleaning fixed equipment in the room. Such lock installations include hook, the sleeve, positioning nut and rectangular plates and other components, and its structure has been specifically designed, and it has the characteristics of no floor damage when equipment is fixed, simple operation, time-saving and labor-saving.

Description

technical field [0001] The invention relates to a locking device, in particular to a locking device for fixing machines or equipment. Background technique [0002] In some high-tech industries such as integrated circuit manufacturing, there are usually many production processes that need to be carried out in a clean room to ensure that the final product will not have fatal defects due to contamination. For example, equipment used in clean rooms such as carts and pod storage (POD storage) is widely used in wafer factories. The main frames of these carts and storages need to be deployed and installed in corresponding positions from time to time. In order to facilitate movement and positioning , these devices are equipped with wheels and locking devices, the role of the locking device is to prevent carts or wafer cassette storage, etc. from falling down in some unforeseen circumstances, such as earthquakes. [0003] However, the currently commonly used equipment locking device...
