Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present utility model.

[0031] Please refer to Figures 1-8The utility model provides a low voltage distribution cabinet convenient to support height adjustment, including low voltage distribution cabinet body 1, the four -around of low voltage distribution cabinet body 1 is provided with vertical beam 2, is provided with multiple sets of support frame 3 between the vertical beam 2 of low voltage distribution cabinet body 1 both sides, the middle part of support frame 3 is provided with locking assembly 4, locking assembly 4 includes the locking cylinder 401 of setting with support frame 3 both sides, the middle part of locking cylinder 401 is provided with locking bolt 402, the outer circumferential side of locking bolt 402 is provided with internal thread sleeve 403, is provided with lock rod 404 at the both sides of internal thread sleeve 403, lock rod 404 includes connecting rod 4041, the top rod 4042 is connected through the pivot of connecting rod 4041, and the end of top rod 4042 is provided with the locating bolt rod 4043, and the outer circumferential side of locating bolt rod 4043 is closer to top rod 4042 and is provided with pressure plate 4044, the both ends of locking cylinder 401 are provided with limit baffle ring 4011, and the inner diameter of limit baffle ring 4011 and locating bolt rod 4043 are mutually matched to make locating bolt rod 4043 eject from the inside of locking cylinder 401 through limit baffle ring 4011, the outer circumferential side of locating bolt rod 4043 is provided with reset spring 405, and reset spring 405 is located between pressure plate 4044 and limit baffle ring 4011 to make locating bolt rod 4043 extrude reset spring 405 through pressure plate 4044, the top end of locking bolt 402 is provided with the clamping groove 4021 for screwdriver engagement, and the outer circumferential side of locking bolt 402 is provided with the thread groove 4022 matched with internal thread sleeve 403, the both sides of internal thread sleeve 403 are provided with rotating seat 4031, and rotating seat 4031 is rotatably connected with connecting rod 4041.

[0032] The locking bolt 402 controls the locking rod to eject from the inside of the locking cylinder 401 through the internal thread sleeve 403.

[0033] The locking assembly 4 is used for fixing the height of the support frame 3.

[0034] The vertical beam 2 is provided with multiple sets of positioning holes 201, and the positioning holes 201 and the top rod 4042 are matched with each other.

[0035] The working principle of the low voltage distribution cabinet convenient to support height adjustment is as follows: the screwdriver is inserted into the clamping groove 4021 at the top end of the locking bolt 402, and the locking bolt 402 is rotated in the counterclockwise direction. With the rotation of the locking bolt 402, the thread groove 4022 on the outer circumferential side of the locking bolt 402 moves relative to the internal thread sleeve 403. Under the restriction of the internal thread sleeve 403, the locking bolt 402 gradually moves upward, thereby driving the connecting rod 4041 connected thereto to move upward, and the reset spring 405 is elastically elongated. The locating bolt rod 4043 is extruded by the pressure plate 4044, and the locating bolt rod 4043 is accommodated into the locking cylinder 401 together with the connecting rod 4041.

[0036] After the locking assembly 4 is released, the height of the support frame 3 is adjusted according to actual needs. The support frame 3 is pushed upward or downward to reach the required height position. During the pushing process, the support frame 3 should be kept stable to avoid tilting or shaking, ensuring the accuracy and safety of the adjustment.

[0037] When the support frame 3 is adjusted to the appropriate height, the locking bolt 402 is rotated clockwise with a screwdriver. The locking bolt 402 moves downward under the action of the threaded groove 4022, pushing the locking rod 404 downward, and the components such as the top rod 4042 and the positioning bolt rod 4043 follow the movement of the connecting rod 4041. The positioning bolt rod 4043 passes through the limiting ring 4011 at both ends of the locking cylinder 401, and finally inserts into the positioning hole 201 on the side of the vertical beam 2, realizing the fixation of the height of the support frame 3.

[0038] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
