DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will further elaborate on the present application through the drawings and embodiments.

[0031] Refer to Figures 1 to 5, an embodiment of the present application provides a power supply cable connector for urban rail transit, including a joint structure 1. The number of joint structures 1 is two, and an adjustable connection structure 2 is provided between the two joint structures 1. The adjustable connection structure 2 includes an adjustment component 21 and two groups of symmetrically arranged guiding components 22. The adjustment component 21 includes an installation shell 211. Inside the installation shell 211, a threaded rod 212 with opposite thread directions on both sides is rotatably installed through a bearing seat. On the outer sides of both ends of the threaded rod 212, threaded barrels 213 are threadedly connected. The tails of the two threaded barrels 213 are respectively fixedly connected to the two joint structures 1. Due to the opposite thread directions on both sides of the threaded rod 212, under the limiting action of the sliding block 218 and the sliding groove 219, the rotating threaded rod 212 can drive the two threaded barrels 213 threadedly connected to it to move in opposite directions. The two threaded barrels 213 then drive the two joint structures 1 to move synchronously in the opposite direction, realizing the adjustment of the distance between the two joint structures 1, with higher flexibility. Thus, it is convenient to appropriately adjust the cable fixing points according to requirements, which is beneficial to improving the connection effect of the cable.

[0032] Referring to Figure 1 , Figure 2 and Figure 3 , in one aspect of this embodiment, an adjustment knob 214 is rotatably installed through one side of the installation shell 211. A first bevel gear 215 is fixedly installed at the tail end of the adjustment knob 214. A second bevel gear 216 meshing with the first bevel gear 215 is fixedly installed on the outer side of the threaded rod 212. By rotating the adjustment knob 214, the first bevel gear 215 can be driven to rotate. The first bevel gear 215 can drive the second bevel gear 216 and the threaded rod 212 meshing with it to rotate, controlling the rotation direction of the threaded rod 212.

[0033] In one aspect of this embodiment, limiting sleeves 217 sleeved on the outer sides of the threaded barrels 213 are fixedly installed on both sides of the installation shell 211. A sliding block 218 is fixedly installed on the outer side of one end of the threaded barrel 213 located inside the limiting sleeve 217. A sliding groove 219 adapted to the sliding block 218 is opened on the inner wall of the limiting sleeve 217, and the sliding block 218 is slidably connected to the sliding groove 219. The sliding block 218 on the outer side of the threaded barrel 213 can slide along the sliding groove 219 on the inner wall of the limiting sleeve 217, playing a role in limiting the stroke of the threaded barrel 213.

[0034] In one aspect of this embodiment, the guiding assembly 22 includes a guiding cylinder 221 and a guiding column 222 respectively and fixedly installed on one side of the two joint structures 1. The guiding column 222 penetrates through the guiding cylinder 221, and a guiding block 223 is fixedly installed at one end of the guiding column 222 located inside the guiding cylinder 221. The guiding block 223 is slidably connected to the inner wall of the guiding cylinder 221. When the two joint structures 1 move, the guiding column 222 and the guiding block 223 will slide along the guiding cylinder 221, playing a role of supporting and limiting, and enhancing the stability of the two joint structures 1.

[0035] Refer to Figure 1 、 Figure 4 and Figure 5 In one aspect of this embodiment, the joint structure 1 includes a mounting collar 11. A plurality of elastic members 12 distributed in a circumferential array are fixedly installed on one side of the mounting collar 11. A clamping block 13 for positioning the cable is fixedly installed on the inner wall of the elastic member 12. A fastening member 14 is arranged outside the elastic member 12. The cable is passed through the middle of the mounting collar 11 and the plurality of elastic members 12, and by tightening the fastening member 14, the elastic member 12 can be pressed, so that the clamping block 13 is tightly attached to the cable to fix the cable.

[0036] In one aspect of this embodiment, internal threads are provided on the inner wall of the fastening member 14, and external threads adapted thereto are provided on the outer walls of the plurality of elastic members 12. The fastening member 14 can be threadedly installed outside the plurality of elastic members 12.

[0037] Working principle: For this power supply cable connector of urban rail transit, the cable is passed through the middle of the mounting collar 11 and the plurality of elastic members 12, and then the adjusting knob 214 is rotated to drive the first bevel gear 215 to rotate. The first bevel gear 215 can drive the second bevel gear 216 and the threaded rod 212 meshing with it to rotate. Since the thread directions on both sides of the threaded rod 212 are opposite, under the limiting action of the sliding block 218 and the sliding groove 219, the rotating threaded rod 212 can drive the two threaded cylinders 213 threadedly connected to it to move in opposite directions. The two threaded cylinders 213 then drive the two joint structures 1 to move synchronously and reversely. After adjusting the distance between the two joint structures 1 to be appropriate, then the fastening member 14 is tightened to press the elastic member 12, so that the clamping block 13 is tightly attached to the cable to fix the cable.
