DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figure 1-4As shown, the copper busbar installation structure of the distribution cabinet includes a distribution cabinet 1 and a copper busbar 4. The middle of the left and right inner walls of the distribution cabinet 1 are fixedly installed with a mounting plate 2. The front of the mounting plate 2 is provided with a socket 21. The two sides of the copper busbar 4 are fixedly installed on the mounting plates 2 on both sides through two locking mechanisms 3. The locking mechanism 3 includes a plug rod 31, a locking sleeve 32, a spring 33 and an extrusion ring 34. The locking sleeve 32 includes a fixed tube 321. The front of the outer surface of the fixed tube 321 is fixedly installed with an anti-slip ring 323. The extrusion ring 34 is sleeved on the outer surface of the fixed tube 321. The rear end of the fixed tube 321 is fixedly installed with a plurality of clamping claws 322 distributed in a ring array. The rear surface of the outer surface of the clamping claw 322 is fixedly installed A baffle 324 is installed, and the ends of several of the clamping claws 322 away from the fixed tube 321 are inclined inwardly, and are combined into an inwardly contracted conical funnel shape, which facilitates the entire locking sleeve 32 to be inserted into the socket 21. The left and right sides of the front end of the copper bar 4 are provided with mounting holes 41. The locking sleeve 32 passes through the mounting holes 41, and the copper bar 4 is arranged between the extrusion ring 34 and the mounting plate 2. The clamping claws 322 are inserted into the socket 21, and the baffle 324 is located at the rear of the socket 21. When the insertion rod 31 is inserted into the locking sleeve 32, several of the clamping claws 322 expand outward, thereby driving the baffle 324 to expand outward, and the mounting plate 2 restricts the baffle 324 so that the locking sleeve 32 will not fall off from the socket 21.
[0022] A knob 311 is fixedly mounted at the front end of the plug rod 31 , and a plurality of anti-slip teeth 312 are evenly arranged around the knob 311 , which can facilitate power workers to plug and unplug the plug rod 31 without causing hand slippage.
[0023] When the insertion rod 31 is not inserted into the locking sleeve 32 , the outer diameter of the annular structure composed of the baffles 324 is smaller than the inner diameters of the insertion hole 21 and the mounting hole 41 , so that the locking sleeve 32 can pass through the mounting hole 41 and the insertion hole 21 .
[0024] The outer surface of the locking sleeve 32 is sleeved with a spring 33, and the spring 33 is located between the anti-slip ring 323 and the extrusion ring 34. When the insertion rod 31 is inserted into the locking sleeve 32, the insertion rod 31 pushes the clamping claws 322 outward, thereby driving the baffle 324 to move outward, and then the elastic force of the spring 33 is used to squeeze the anti-slip ring 323 to drive the entire locking sleeve 32 to move forward, and drive the baffle 324 to squeeze the mounting plate 2, so that the locking sleeve 32 is installed more firmly.
[0025] The locking sleeve 32 is made of plastic, and the clamping jaws 322 can be expanded outwards and contracted inwards by utilizing the elasticity of the plastic.
[0026] Example 2
[0027] This embodiment is implemented on the basis of embodiment 1, the insertion rod 31 and the fixed tube 321 are threadedly connected, and the insertion rod 31 is driven to move into the locking sleeve 32 by rotating the insertion rod 31, so that the clamping claw 322 is pushed outward, thereby driving the baffle 324 to move outward, and the baffle 324 is restricted by the mounting plate 2, so that the locking sleeve 32 will not fall off, and the insertion rod 31 and the fixed tube 321 are threadedly connected, the insertion rod 31 will not fall off, and the connection is more stable.
[0028] The working principle of the utility model is as follows: when in use, the spring 33 and the extrusion ring 34 are sequentially inserted into the surface of the locking sleeve 32, and then the rear end of the locking sleeve 32 is sequentially passed through the mounting hole 41 of the copper bus 4 and the insertion hole 21 of the mounting plate 2, and finally the insertion rod 31 is inserted into the locking sleeve 32 from the front, and the insertion rod 31 opens the clamping claw 322 outward, thereby driving the baffle 324 to move outward and be located outside the insertion hole 21, and then under the action of the elastic force of the spring 33, the entire locking sleeve 32 is driven to move forward, thereby driving the baffle 324 to move forward and squeeze the mounting plate 2, thereby limiting the locking sleeve 32 in the insertion hole 21, preventing the locking sleeve 32 from falling off, and thus fixing the copper bus 4 on the mounting plate 2.
[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
