Description

Technical Field

[0001] The utility model relates to the technical field of cable protection for explosion-proof electrical appliances, in particular to a cable protection tube. Background Art

[0002] Explosion-proof electrical appliances, as the name suggests, are electrical appliances that can prevent explosion accidents in situations containing explosive and dangerous gas mixtures.

[0003] Cables are commonly used connecting wires for explosion-proof electrical appliances and are important components to ensure the normal operation of explosion-proof electrical appliances. Cables need to be protected, and cable protection tubes are commonly used protection structures. Existing cable protection tubes are mostly made of steel, PVC (polyvinyl chloride) materials, and polyethylene materials to form a single protection tube sleeve that is installed on the outside of the cable. The structure is simple. After the protection tube is installed on the outside of the cable, the cable will contact the inner side of the protection tube, resulting in that when the protection tube is squeezed, it is easy to squeeze the cable body, which may seriously cause damage to the cable. At present, the protection tube cannot be reused. When the protection tube needs to be removed, it can only be cut off, which causes waste. For this reason, we propose a cable protection tube.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a cable protection tube, comprising an upper shell 1 and a lower shell 2, which can form a protection tube after being spliced and combined, a splicing component 3 is provided at the bottom of the upper shell 1 and the top of the lower shell 2, and a driven component 4 for positioning the cable is provided inside the upper shell 1 and the lower shell 2, and the driven component 4 includes: a movable groove 41, an arc plate 42, a return spring 43, a resistance groove 44, a through groove 45, and a resistance plate 46.

[0024] A moving groove 41 is provided inside the upper shell 1, and an arc plate 42 is slidably installed inside the moving groove 41. A return spring 43 is fixed inside the moving groove 41. One end of the return spring 43 away from the moving groove 41 is fixed to the arc plate 42. A resistance groove 44 is provided on the arc plate 42. A through groove 45 is provided inside the upper shell 1. The through groove 45 is penetrated by the resistance plate 46 and is hinged to the resistance plate 46. The resistance plate 46 extends into the resistance groove 44. When the upper shell 1 and the lower shell 2 are moved, After splicing, the upper shell 1 and the lower shell 2 contact each other. At this time, the arc plate 42 is contacted and retracted into the movable groove 41. The contact groove 44 opened on the arc plate 42 can contact the contact plate 46, so that the contact plate 46 is swung and supported at the position hinged with the through groove 45. The multiple groups of contact plates 46 can support the cables between the upper shell 1 and the lower shell 2, ensuring that the cables can be in the center position between the upper shell 1 and the lower shell 2, so as to better protect the cables.

[0025] There are two groups of driven components 4, one group of driven components 4 is arranged on the upper shell 1, and the other group of driven components 4 is arranged on the lower shell 2. The two groups of driven components 4 are arranged in a circular array with the center of the circle after the upper shell 1 and the lower shell 2 are spliced as the axis, which can better support the cables.

[0026] The splicing component 3 includes a plug-in block 31, a plug-in block 31 is fixed to the bottom of the upper shell 1, and a clamping rod 32 is fixed to the surface thereof, a slot 33 is provided at the top of the lower shell 2, a clamping groove 34 is provided on the inner side of the slot 33, a push block 35 is slidably installed on the inner side of the slot 33, a connecting spring 36 is fixed to the inner side of the slot 33, and the end of the connecting spring 36 away from the slot 33 is fixed to the push block 35, when the plug-in block 31 at the bottom of the upper shell 1 is inserted into the slot 33 at the top of the lower shell 2, the clamping rod 32 on the surface of the plug-in block 31 can be inserted into the clamping groove 34 on the inner side of the slot 33 to complete the splicing of the upper shell 1 and the lower shell 2.

[0027] A chamfered surface is provided on the top of the push block 35. When the upper shell 1 and the lower shell 2 are spliced, the arc plate 42 can first abut against the chamfered surface of the push block 35, so that the push block 35 moves to the side close to the connecting spring 36. When the plug-in block 31 is inserted into the slot 33, the plug-in block 31 can abut against the chamfered surface of the push block 35 to push the push block 35 to move. When the plug-in block 31 is fully inserted, under the action of the connecting spring 36, the push block 35 can push the plug-in block 31 with the card rod 32 into the card slot 34. By the push block 35 abutting against the plug-in block 31, the stability of the splicing of the upper shell 1 and the lower shell 2 can be guaranteed.

[0028] The surface of the abutment plate 46 is sleeved with a sponge pad 5 . When the abutment plate 46 supports the cable, the sponge pad 5 contacts the surface of the cable. The soft sponge pad 5 can further protect the cable.

[0029] In the utility model, when in use, the cable of the explosion-proof electrical appliance is placed on the inner side of the lower shell 2, and the plug-in block 31 at the bottom of the upper shell 1 is aligned with the slot 33 at the top of the lower shell 2 and inserted. The arc plate 42 first abuts against the beveled surface of the push block 35, so that the push block 35 moves to the side close to the connecting spring 36. When the plug-in block 31 is inserted into the slot 33, the plug-in block 31 can abut against the beveled surface of the push block 35 to push the push block 35 to move. When the plug-in block 31 is fully inserted, under the action of the connecting spring 36, the push block 35 can push the plug-in block 31 with the card rod 32 into the card slot 34. By the push block 35 abutting against the plug-in block 31, the stability of the splicing of the upper shell 1 and the lower shell 2 can be guaranteed.

[0030] At the same time, the arc plate 42 is retracted into the movable groove 41 by the resistance, and the resistance groove 44 opened on the arc plate 42 can resist on the resistance plate 46, so that the resistance plate 46 is swung and supported at the position hinged with the through groove 45. The multiple groups of resistance plates 46 can support the cables between the upper shell 1 and the lower shell 2, ensuring that the cables can be in the center position between the upper shell 1 and the lower shell 2, so as to better protect the cables.

[0031] When it is necessary to separate the upper shell 1 and the lower shell 2, it is only necessary to pull the upper shell 1 to move toward the side close to the push block 35. While the plug-in block 31 is moving against the push block 35, the plug-in block 31 can withdraw from the card slot 34 with the card rod 32, thereby releasing the limit between the upper shell 1 and the lower shell 2, and the upper shell 1 and the lower shell 2 can be separated. After separation, the arc plate 42 is no longer resisted. Under the action of the reset spring 43, the arc plate 42 is reset. The arc plate 42 resists the resistance plate 46 through the resistance groove 44 opened on itself, so that the resistance plate 46 rotates and resets at the position hinged with the through groove 45, completing the reset of the device.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
