Description

Technical Field

[0001] The utility model relates to the technical field of new phase sequence plates, in particular to a new phase sequence plate which is light, flexible to install and easy to disassemble. Background Art

[0002] Phase sequence signs are used inside utility distribution boxes or switch boxes to indicate the connection status and voltage level of power lines. These signs typically feature different colors, text, or icons to indicate specific functions or information. They are widely used in industrial and electrical equipment to ensure correct power line connections and prevent operational errors.

[0003] A Chinese patent discloses a new type of phase sequence sign (authorization announcement number CN212380086U). The patented technology includes a phase sequence sign body, a fixed plate, a support frame, two sets of adjustment screws and an adjustment threaded tube. The rear end of the support frame is fixedly connected to the front end top of the fixed plate, and the front end of the support frame is rotatably connected to the rear end top of the phase sequence sign body. One end of the two sets of adjustment screws are rotatably connected to the front end bottom of the fixed plate and the rear end bottom of the phase sequence sign body, respectively. The other ends of the two sets of adjustment screws are respectively inserted into and screwed into the two ends of the adjustment threaded tube. A cavity is provided inside the phase sequence sign body, and the middle part of the cavity is reserved for phase sequence letters. The cavity is filled with luminous powder. The front end of the phase sequence sign body is provided with an observation hole communicating with the cavity, and a transparent baffle is provided at the observation hole.

[0004] This patented technology has the advantages of easy observation and angle adjustment during use, but there are still some shortcomings during use. The new phase sequence plate has large installation structural parts during use, is fixed and installed by bolts, is cumbersome to disassemble, and is heavy to use. Therefore, those skilled in the art provide a new phase sequence plate that is light, flexible to install, and easy to disassemble to solve the problems raised in the above background technology.

[0038] Example 1

[0039] See also Figures 1-6 As shown, this embodiment is a new phase sequence sign that is light, flexible to install, and easy to disassemble, including a sign body 100,

[0040] The mounting structure 200 includes a card plate 1 201 and a card plate 2 202 located at the rear end of the card body 100, a cable tie 203 connected to the card plate 1 201, a mounting tube 207 located at the rear side of the card body 100, a bearing 2 217 embedded and installed inside the two ends of the mounting tube 207, a mounting shaft 216 rotatably inserted into the bearing 2 217, a gear 218 sleeved on the outer wall of the mounting shaft 216, and equidistantly distributed teeth 204 located at one end of the cable tie 203.

[0041] A through hole 205 is formed at one end of the card plate 201, and one end of the cable tie 203 slides through the through hole 205;

[0042] The travel holes 209 are symmetrically distributed, the cable tie 203 passes through the two travel holes 209, the gear 218 is located at the travel hole 209, and the outer wall of the cable tie 203 is engaged with the gear 218;

[0043] The screw 211 is located at one end of the outer side of the mounting tube 207 and is provided with a torsion ring 208. The outer wall of the torsion ring 208 is provided with anti-slip grooves. One end of the mounting tube 207 is provided with a bracket 206 connected to the back of the card body 100.

[0044] Using the card body 100;

[0045] Card plate 1 201 and card plate 2 202 are sleeved on the outside of the structural part that needs to be fixed. At the same time, one end of the cable tie 203 passes through the through hole 205 and is inserted into the inside of the travel hole 209. The tooth 204 on the outer wall of the cable tie 203 engages with the gear 218, and the gear 218 fixes the tooth 204, thereby fixing the cable tie 203. The cable tie 203 is bound to the outer wall of the object to firmly fix the sign body 100. The sign body 100 is the new phase sequence sign body, which is effectively identified.

[0046] Example 2

[0047] See also Figures 1-6 As shown, this embodiment is based on embodiment 1 and also includes:

[0048] A spiral groove 215 is formed on the outer wall of the mounting shaft 216, a bearing 210 is embedded in the mounting cylinder 207, a screw 211 is rotatably inserted into the bearing 210, a threaded sleeve 213 is located outside the screw 211 and is threadedly sleeved with the screw 211, a protruding shaft 219 is located at one end of the threaded sleeve 213 and one end is located inside the spiral groove 215, a travel hole 209 is formed inside one end of the mounting cylinder 207,

[0051] Performing use of the mounting structure 200;

[0052] Grab the torsion ring 208 and drive the screw 211 to rotate. Because the threaded sleeve 213 is guided by the slider 214, the screw 211 pushes the threaded sleeve 213, driving the convex shaft 219 to push the spiral groove 215. The ball 220 rolls on the inner wall of the spiral groove 215, thereby driving the installation shaft 216 to rotate. When the installation shaft 216 rotates, it drives the gear 218 to rotate. The gear 218 pushes the latch 204, thereby pushing the cable tie 203 out of the travel hole 209, and the cable tie 203 moves out of the installation tube 207, so that the cable tie 203 is loose, loosening the card body 100, and the card body 100 is released.
