[0004] The existing vertical explosion-proof distribution boxes are designed with a fixed assembly for the box body and the upright frame, making it difficult to adjust them according to the needs of industrial production. It is also difficult to adjust the longitudinal position of the cabinet body, resulting in poor flexibility and adaptability in application.

[0005] Therefore, an explosion-proof distribution box is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an explosion-proof distribution box in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0028] like Figure 1-5 As shown, an explosion-proof distribution box includes a distribution box body 1. Limiting sleeves 2 are fixedly installed at the corners of the back side of the distribution box body 1. A longitudinal column 3 is slidably connected inside the limiting sleeve 2. A top support pipe 4 and a bottom bracket 5 are fixedly installed at the top and bottom ends of the longitudinal column 3, respectively. A locking sliding sleeve 6 is fixedly installed in the middle of the back side of the distribution box body 1. A locking prism tube 7 with internal communication is fixedly installed in the middle of the side wall of the locking sliding sleeve 6. A longitudinal plate frame 8 and a steel cable pulley mechanism 9 are fixedly provided on the inner wall of the locking prism tube 7. The inside of the locking prism tube 7 and the slot connecting it to the side wall of the locking sliding sleeve 6 are slidably inserted. The device includes a locking slide plate 10 and a locking contact rubber seat 11, which are fixedly connected. A locking spring 12 is fixedly connected to the opposing sides of the locking slide plate 10 and the longitudinal plate frame 8. A stable truncated cone base 13 is fixedly installed in the middle of the side of the locking slide plate 10 near the locking spring 12. A steel cable 14 is fixedly installed at the end of the stable truncated cone base 13. A T-shaped branch tube 16 is fixedly installed in the middle of the steel cable 14. A longitudinal ring 15 that slides and is sleeved on the T-shaped branch tube 16 is fixedly inserted into the middle of the bottom wall of the locking prism tube 7. A touch handle seat 17 is fixedly installed at the bottom end of the T-shaped branch tube 16.

[0029] like Figure 1As shown, inclined support arms 19 are fixedly installed on the surfaces of the limiting sleeve 2 and the locking sliding sleeve 6. The end of the inclined support arm 19 away from the limiting sleeve 2 or the locking sliding sleeve 6 is fixedly connected to the back side of the distribution box body 1. An expansion frame sleeve 18 communicating with it is fixedly connected to the middle of the top wall of the locking prism tube 7.

[0030] More specifically, by setting the inclined support arm 19 to provide the fixation of the limiting longitudinal sleeve 2 and the locking sliding sleeve 6, the structural stability is improved, and by setting the extension frame sleeve 18, the T-shaped branch pipe 16 can move a large space during the upward movement.

[0031] like Figure 1 As shown, the base support 5 includes a frame base 501, a frame inclined support pipe 502 and a bottom horizontal pipe 503. The two ends of the frame inclined support pipe 502 are fixedly connected to the frame base 501 and the longitudinal column 3 respectively, and the two ends of the bottom horizontal pipe 503 are fixedly connected to the longitudinal column 3.

[0032] More specifically, by setting up the inclined support pipe 502 and the bottom horizontal pipe 50 of the upright base 501 and the bottom of the longitudinal column 3 to strengthen the support, the stability and strength of the structure are improved.

[0033] like Figure 3 As shown, the longitudinal frame 8 includes a supporting longitudinal piece 801 and a cable channel groove 802. The cable channel groove 802 is opened through the middle of the supporting longitudinal piece 801. The steel cable 14 is located on the inner wall of the cable channel groove 802 and does not contact its inner wall.

[0034] More specifically, by providing the cable channel groove 802, a movement channel for the cable 14 during displacement can be provided.

[0035] like Figure 4 As shown, the steel cable pulley mechanism 9 includes a pulley fixed shaft 901, a pulley bearing 902, and a concave pulley 903. The concave pulley 903 is rotatably sleeved on the middle part of the surface of the pulley fixed shaft 901 through the pulley bearing 902. The end of the pulley fixed shaft 901 is fixedly connected to the front and back sides of the inner wall of the locking tube 7. The outer ring of the concave pulley 903 is a concave ring. There are two pulley fixed shafts 901, pulley bearings 902, and concave pulleys 903. The two concave pulleys 903 are slidably overlapped above and below the surface of the steel cable 14, respectively.

[0036] More specifically, by setting two concave pulleys 903 to slide and overlap above and below the surface of the steel cable 14 respectively, the steel cable 14 can be wrapped and bound, making it less likely to disengage from the outer edge of the concave pulley 903, thus improving stability.

[0037] like Figure 5As shown, the locking rubber base 11 includes a locking rubber plate 1101 and an anti-slip horizontal groove 1102. The anti-slip horizontal groove 1102 is formed on the side of the locking rubber plate 1101 near the locking control sleeve 6.

[0038] More specifically, by setting anti-slip grooves 1102 on the side surface of the locking rubber plate 1101, the friction of the locking rubber plate 1101 is increased when it is pressed against the side surface of the longitudinal column 3, making the pressing between the locking rubber plate 1101 and the longitudinal column 3 more secure and less likely to slip off.

[0039] Working principle: When adjusting the longitudinal height of the distribution box body 1, the operator supports the locking prism tube 7 and lifts the touch handle seat 17 upwards, causing the T-shaped branch tube 16 to slide upwards within the longitudinal ring 15. This causes the middle part of the steel cable 14 to push upwards, allowing the steel cable 14 to slide on the concave pulley 903 surface of the steel cable pulley mechanism 9. The steel cable 14 then pulls and stabilizes the truncated cone seat 13 and the locking slide plate 10, thereby moving the locking slide plate 10 and the locking contact rubber seat 11. Once the locking contact rubber seat 11 is disengaged from the longitudinal column 3, the locking prism tube 7 can be moved longitudinally, thereby moving the locking sliding sleeve 6 and the distribution box body 1 longitudinally. When the desired height is reached, the touch handle seat 17 is released, allowing the locking slide plate 10 and the locking contact rubber seat 11 to displace under the reset action of the locking spring 12. The locking contact rubber seat 11 continues to press against the longitudinal column 3, thus fixing it again.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
