[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The embodiment of the utility model discloses an explosion-proof control box with good sealing performance.

[0026] Example 1

[0027] The utility model provides Figure 1-3 The explosion-proof control box shown has good sealing performance and includes an explosion-proof control box 1 and a button 2 arranged on the outside of the explosion-proof control box 1. The characteristics are that a support tube 3 is fixedly penetrated through the outer wall of the explosion-proof control box 1, a movable tube 4 is slidably penetrated inside the support tube 3, a connecting rod 5 is penetrated inside the movable tube 4, the button 2 is fixedly connected to the connecting rod 5, a first spring 6 is provided inside the support tube 3, and the two ends of the first spring 6 are respectively fixedly connected to the inner wall of the movable tube 4 and the support tube 3;

[0028] A telescopic sealing tube 7 is provided between the button 2 and the explosion-proof control box 1. The telescopic sealing tube 7 is a corrugated tube. Sealing rings 8 are fixedly provided at both ends of the telescopic sealing tube 7. The telescopic sealing tube 7 is sleeved on the outside of the support tube 3. The two sealing rings 8 are fixedly connected to the button 2 and the explosion-proof control box 1 respectively. The two sealing rings 8 are connected to the button 2 and the explosion-proof control box 1 by hot melt.

[0029] When the explosion-proof control box 1 is in use, the button 2 can be connected to the movable tube 4, and through the setting of the first spring 6, it can be pressed stably to effectively control the control box. At the same time, when the button 2 is in use, the telescopic sealing tube 7 is sleeved on the outside of the support tube 3 and the movable tube 4, and under the fixation of the sealing tube 8, the space between the button 2 and the explosion-proof control box 2 is effectively sealed, which can effectively prevent external substances from entering the control box, thereby improving the sealing performance of the explosion-proof control box 1. At the same time, since the telescopic sealing tube 7 is a corrugated tube, the button 2 can be pressed normally and stably, and will not affect the normal use of the explosion-proof control box 1.

[0030] Example 2

[0031] Example 2 is based on Example 1 in order to stably set the telescopic sealing tube 7 between the button 2 and the explosion-proof control box 1, as shown in FIG. Figure 2-3As shown, grooves are provided on both sides of the rod wall of the connecting rod 5, and an insert block 9 is provided in the groove. A second spring 10 is fixed between the insert block 9 and the inner wall of the groove. Slide grooves 13 are provided on both sides of the inner wall of the groove. A slide plate 14 is fixedly passed through the interior of the insert block 9, and the two ends of the slide plate 14 are respectively slidably provided in the two slide grooves 13. The tube wall of the movable tube 4 is provided with two symmetrically arranged slots 11, and the end of the insert block 9 is inserted into the slot 11. A guide slope 12 is provided on the side of the end of the insert block 9 close to the explosion-proof control box 1.

[0032] When installing the telescopic sealing tube 7, first separate the connecting rod 5 from the mobile tube 4. At this time, the telescopic tube sealing tube 7 can be put on the outside of the connecting rod 5 first, and then the connecting rod 5 is inserted into the mobile tube 4. As the connecting rod 5 continues to be inserted, the plug block 9 is squeezed by the tube mouth of the mobile tube 4 through its outer guide slope 12, so that the plug block 9 squeezes the second spring 10 and enters the groove. During this process, the sliding cooperation of the slide 14 and the slide groove 13 supports the movement of the plug block 9. When the connecting rod 5 is inserted into a certain position in the mobile tube 4, the elastic force of the second spring 10 is restored to make the plug block 9 inserted into the slot 11, completing the connection between the connecting rod 5 and the mobile tube 5, so that the button 2 can be pressed stably, and then the sealing ring 8 is connected to the button 2 and the explosion-proof control box 1 to complete the setting of the telescopic sealing tube 7.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
