Detailed Description

The utility model is further described below with reference to examples, but not to be construed as being limited thereto, and any number of modifications which can be made by anyone within the scope of the claims are also within the scope of the claims.

Referring to fig. 1-3, the multifunctional power box of the utility model comprises a power box body 14 and a cabinet door 1. The cabinet door 1 is provided with an explosion-proof glass window 15. The staff can observe the controller in the power box through the explosion-proof glass window 15. The power box body 14 is internally provided with a controller. A plurality of mounting holes corresponding to the keys on the controller one to one are formed in the cabinet door 1, the buttons 2 are movably inserted in the mounting holes, and the buttons 2 are connected with the mounting holes in a clearance fit mode. The outside of button 2 is equipped with the sealed cushion 7 of its parcel, and one side of sealed cushion 7 is equipped with air cushion 13, and the coloured gas is equipped with in the air cushion 13, and sealed cushion 7 and air cushion 13 all pass through sealing ring 8 fixed mounting on the outer wall of cabinet door 1. The end of the button 2 is provided with a mandril 3 which can reset automatically, and the end of the mandril 3 is contacted with the button of the controller.

The sealing cushion 7 can effectively seal the button 2. However, in the using process of the button 2, the problem that the sealing cushion 7 is broken and punctured due to collision of a foreign object in the using process is inevitable, and finally the power box is not sealed, so that a large potential safety hazard is caused. While the hole in the sealing cushion 7 is difficult to observe, in order to further reduce the risk, the air cushion 13 is additionally arranged above the sealing cushion 7 in the embodiment. When the collision of a foreign object occurs, the foreign object firstly collides with the air cushion 13, for example, the air cushion 13 is broken, and the air in the air cushion can leak, so that the air cushion 13 contracts or the air is reduced, and the air is easily observed by a worker, thereby achieving the purpose of reducing the risk. Through the arrangement of the sealing soft cushion 7 and the air cushion 13, the safety of the power supply box in use in dangerous places is greatly improved.

Preferably, the sealing cushion 7 is a silicone cushion. Due to the soft performance of the silica gel cushion, the operability of the button 2 is ensured.

Preferably, a sealant is coated between the sealing cushion 7 and the air cushion 13 and the sealing ring 8 to ensure the sealing performance between the sealing cushion 7 and the air cushion 13 and the sealing ring 8.

A plurality of mounting boxes 4 corresponding to the mounting holes one by one are mounted on the inner side of the cabinet door 1, and the ejector rods 3 penetrate through the mounting boxes 4 and extend to the front ends of the controller keys. A limiting ring 5 is arranged between the ejector rod 3 and the button 2, and a spring 6 is sleeved on the ejector rod 3 between the limiting ring 5 and the mounting box 4. After the operator releases the button 2, the button 2 automatically resets under the action of the spring 6, so that the ejector rod 3 is separated from the key, and one-time operation on the key is completed.

The jack 3 of the present embodiment has a Z-shape. The one end that the button 2 was kept away from to mounting box 4 is installed locating component, and locating component and ejector pin 3's end-to-end connection. In the current power box applied to explosion-proof places, the button rod is a cylindrical rod. However, the distance between most of the controller buttons and the display screen is small, so that the distance between the operation button on the cabinet door 1 and the explosion-proof glass window 15 is very compact, the design is inconvenient, and even the area of the button has to be reduced, so that the operation is very inconvenient. And the power supply box of this embodiment sets ejector pin 3 into the Z shape, can effectual solution button 2 and the little problem of the 15 intervals of explosion-proof glass window on the cabinet door 1, has improved the maneuverability of button 2. The positioning assembly is used for ensuring the stability of the ejector rod 3 in the moving process, and the problem that the ejector rod 3 deviates from the position of the key due to too large self oscillation amplitude caused by external vibration in the moving process is solved.

The locating component of this embodiment includes flexible post 9 and connecting rod 10, and the tip at mounting box 4 is installed to the one end of flexible post 9, and the other end at flexible post 9 is installed to the one end of connecting rod 10, is equipped with installation head 11 on the ejector pin 3 in the mounting box 4 outside, and the other end of connecting rod 10 is installed on installation head 11. Specifically, the telescopic direction of the telescopic column 9 is consistent with the moving direction of the button 2, the connecting rod 10 is fixedly connected with the telescopic column 9 and the ejector rod 3, and the connecting end of the connecting rod 10 and the ejector rod 3 is close to the tail end of the ejector rod 3. When button 2 is pressed, ejector pin 3 removes, drives flexible post 9 through the combined action of connecting rod 10 and extends to at the in-process that removes, through flexible post 9 and connecting rod 10 to ejector pin 3's location, improved ejector pin 3 at the stability of removal in-process.

Preferably, a conical operating head 12 is arranged on one side of the ejector rod 3 close to the controller key, and the area of the end surface of the conical operating head 12 is smaller than the surface area of the key, so as to ensure that the conical operating head 12 can still operate the key within a certain offset range of the ejector rod 3. The outside of toper operating head 12 is wrapped up one deck antiskid silica gel layer, guarantees the contact stability of toper operating head 12 and button, avoids appearing toper operating head 12 and takes place relative slip with the button in operation process and lead to the problem of pressing in vain.

Preferably, the mandril 3 comprises a steel mandril 31 and a plastic coat 32, the plastic coat 32 wraps the steel mandril 31, and the conical operating head 12 and the plastic coat 32 are of an integrated structure. Through such setting, can effectual improvement ejector pin 3 rigidity, guarantee ejector pin 3's durable degree and ejector pin 3's operating performance.

Preferably, an antistatic layer is embedded between the air cushion 13 and the sealing cushion 7.

The working principle of the utility model is as follows: when the staff pressed the button 2, the action of button 2 drove ejector pin 3 and moves towards the button direction, and spring 6 contracts under the effect of spacing ring 5. When the ejector rod 3 is contacted with the key, the push rod 3 can continuously move to realize the operation of the key. When the user releases the button 2, the button 2 automatically resets under the action of the spring 6, so that the ejector rod 3 is separated from the key, and one-time operation on the key is completed.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various changes and modifications without departing from the structure of the utility model, which will not affect the effect of the utility model and the practicability of the patent.
