[0021] The present application is further described in detail below in conjunction with the accompanying drawings.

[0022] The embodiment of the present application discloses a wire pulling resistance structure of a lighting fixture.

[0023] Reference Figure 1 , Figure 2 The wire pulling resistance structure of the lamp includes a mounting seat 1 for fixing on the inner side wall of the lamp holder, and a threading tube 5 for setting on the lamp holder for the power line to enter and exit the lamp holder. The mounting seats 1 are symmetrically arranged on both sides of the threading tube 5, and a wire fixing plate 2 is arranged between two adjacent mounting seats 1. A clearance groove 11 is formed between the wire fixing plate 2 and the bottom inner side wall of the lamp holder, and the clearance groove 11 facilitates the installer to insert his fingers into the clearance groove 11, and then take out the wire fixing plate 2 from between the mounting seats 1 on both sides.

[0024] like Figure 2 , Figure 3 As shown, the fixing plate 2 has a plurality of fixing holes 20 for the power cord to pass through, and the fixing holes 20 are arranged in sequence and at intervals on the fixing plate 2. The mounting base 1 is provided with mounting grooves 10, and the two sides of the fixing plate 2 are inserted and limited in the respective opposite mounting grooves 10 along a direction perpendicular to the direction in which the power cord passes through the lamp holder.

[0025] like Figure 2 , Figure 3 As shown, the mounting base 1 is provided with a locking member 3 for locking the wire fixing plate 2 in the mounting groove 10. The locking member 3 is slidably arranged outside the mounting base 1 along the direction in which the power line is passed through the lamp holder. The opening surface of the mounting groove 10 for inserting the wire fixing plate 2 into the mounting base 1 is located on the sliding path of the respective opposite locking members 3, and the locking members 3 are used to cover the opening surface of the respective mounting grooves 10.

[0026] like Figure 2 , Figure 3As shown, the mounting seat 1 is also provided with a return spring 4 for pushing the locking member 3 until the opening surface of the mounting groove 10 is covered, and the return spring 4 is retracted along the sliding direction of the locking member 3. One end of the return spring 4 is in conflict with the inner side wall of the mounting seat 1, and the other end of the return spring 4 is in conflict with the outer side wall of the respective opposite locking member 3. The locking member 3 is pushed by the respective return springs 4 to keep the opening surface of the mounting groove 10 covered. At this time, the wire fixing plate 2 can be locked on the mounting seat 1 under the action of the locking member 3, so that the wire fixing plate 2 is not easy to be separated from the mounting groove 10.

[0027] like Figure 2 , Figure 3 As shown, a guide slope 30 is provided on the side wall of the locking member 3 away from the mounting groove 10. The guide slope 30 is located on the side of the locking member 3 away from the reset spring 4, and the guide slope 30 is inclined downward in a direction away from the reset spring 4. When installing the wire fixing plate 2, by pressing the wire fixing plate 2 along the guide slope 30 toward the mounting groove 10, under the guidance of the guide slope 30, the locking member 3 will gradually move out from the opening surface of the mounting groove 10 and continuously compress the reset spring 4. When the locking member 3 is completely moved out from the opening surface of the mounting groove 10, the wire fixing plate 2 can be smoothly inserted into the mounting groove 10, and then the locking member 3 will automatically reset under the elastic force of the reset spring 4, and the opening surface of the mounting groove 10 will be covered again, thereby locking the wire fixing plate 2 on the mounting seat 1.

[0028] like Figure 2 , Figure 3 As shown, the power cord is inserted into the threading tube 5, and a sealing rubber sleeve 50 is coaxially arranged in the threading tube 5. The sealing rubber sleeve 50 is made of rubber with a certain elastic deformation ability. The sealing rubber sleeve 50 is sleeved on the outside of the power cord, and the inner wall of the sealing rubber sleeve 50 and the outer wall of the power cord are in contact with each other. Under the action of the sealing rubber sleeve 50, the waterproof sealing performance of the threading tube 5 can be greatly improved, so that rainwater is not easy to flow into the lamp holder through the threading tube 5.

[0029] like Figure 2 , Figure 3 As shown, a limit ring 51 is coaxially fixedly provided on the inner wall of the threading tube 5, the limit ring 51 is located on the side of the sealing rubber sleeve 50 away from the mounting seat 1, and the limit ring 51 and the outer wall of the sealing rubber sleeve 50 are in contact with each other. The sealing rubber sleeve 50 is limited in the threading tube 5 by the limit ring 51, thereby effectively preventing the sealing rubber sleeve 50 from escaping from the threading tube 5.

[0030] like Figure 2 , Figure 3As shown, the outside of the threading tube 5 is coaxially threaded with a fastener 52, and the threading tube 5 is detachably mounted on the lamp holder through the fastener 52. In this embodiment, the fastener 52 is a nut. When the threading tube 5 is fixedly mounted on the lamp holder through the fastener 52, the fastener 52 will fit with the inner wall of the lamp holder, and the side wall of the end of the threading tube 5 located outside the lamp holder will fit with the outer wall of the lamp holder.

[0031] The implementation principle is: the power cord is snake-shaped and passed through the wire fixing hole 20 in sequence. When the power cord is pulled by external force, the power cord can be firmly limited on the wire fixing plate 2, so that the power cord is not easily displaced; thereby ensuring the reliability of the connection between the power cord and the LED light strip, and the connection between the two is not prone to breakage, thereby greatly enhancing the tensile strength of the lighting power cord, thereby further improving the service life of the lighting.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
