[0007] The inner sides of both ends of the U-shaped plate are respectively provided with clamping blocks, and both sides of the plugging plate are provided with clamping grooves, and the clamping blocks on the inner sides of both ends of the U-shaped plate are clamped in the clamping grooves on both sides of the plugging plate.

[0008] Elastic reinforcing plates are respectively arranged on the outer sides of both ends of the U-shaped plate.

[0009] The elastic reinforcing plate is L-shaped and matches with the two ends of the U-shaped plate.

[0010] The two ends of the elastic reinforcing plate are respectively fixed on the U-shaped plate through U-shaped sleeves.

[0011] Two movable rods are arranged between the U-shaped plate and the plugging plate, and each movable rod is provided with a spring.

[0012] The upper end of the movable rod passes through the U-shaped plate and is fixedly connected with the buckle plate, and the lower end of the movable rod is provided with a limiting circular plate that contacts the plug plate.

[0013] The limiting hole and the notch are both provided with protective sleeves.

[0014] The snap plate is a T-shaped structure.

[0015] The beneficial effects of the utility model are as follows: firstly, the power cord on the plug is inserted into the limiting hole through the notch, and then the plug is plugged into the socket on the plug board, and then the U-shaped plate is buckled on the plug board, thereby preventing the plug from shaking on the plug board and preventing the plug from falling off from the socket, thereby ensuring the stability of the power input of the electrical equipment.

DETAILED DESCRIPTION

[0022] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0023] Refer to the attached Figure 1-5 A plug fixing structure for an extension board socket comprises a plug board 1 and a plurality of plugs (2) plugged into the plug board 1, each plug 2 is provided with an anti-dropping component, the anti-dropping component comprises a U-shaped plate 3 and a snap plate 4, both ends of the U-shaped plate 3 are snapped onto the plug board 1, the snap plate 4 is fixed onto the U-shaped plate 3, a limiting hole 6 matching with the power cord of the plug 2 is provided on the snap plate 4, and a notch 5 matching with the power cord of the plug 2 is provided on the limiting hole 6.

[0024] In this embodiment, if Figures 1 to 5As shown, the extension board plug jack fixing structure comprises a plug board 1 and a plurality of plugs 2 inserted in the plug board 1 plug sockets, a plurality of anti-dropping components for fixing the plugs 2 are arranged above the plug board 1, and the anti-dropping components comprise a U-shaped plate 3, a snap plate 4 arranged above the U-shaped plate 3, a notch 5 opened in the center of one side of the snap plate 4 and a limiting hole 6 opened inside the snap plate 4; both ends of the U-shaped plate 3 are snapped with the side wall of the plug board 1, the U-shaped plate 3 is made of elastic material, and the U-shaped plate 3 is made of steel material here, and the notch 5 is opened in the center of the one side of the snap plate 4 and the limiting hole 6 is opened in the inside of the snap plate 4; 5 is communicated with the limiting hole 6, the wire on the plug 2 can enter the limiting hole 6 through the notch 5, the limiting hole 6 presses down the plug 2 to realize the firm installation between the plug 2 and the plug board 1, an elastic component is arranged between the U-shaped plate 3, the buckle plate 4 and the plug board 1, the elastic component includes a movable rod 7 symmetrically inserted on the U-shaped plate 3, a limiting circular plate 8 arranged at the lower end of the movable rod 7 and a spring 9 sleeved on the movable rod 7, the top of the movable rod 7 is fixedly connected with the buckle plate 4, and the spring 9 is located below the U-shaped plate 3.

[0025] In this embodiment, isosceles trapezoidal blocks 10 are symmetrically arranged on the inner walls at both ends of the U-shaped plate 3, and slots 11 adapted to the blocks 10 are symmetrically opened on both side walls of the plug board 1. The blocks 10 and the slots 11 cooperate with each other to elastically connect the U-shaped plate 3 and the plug board 1 together.

[0026] The first U-shaped sleeves 12 are symmetrically arranged on the outer side walls at both ends of the U-shaped plate 3, and the second U-shaped sleeves 13 are symmetrically arranged on the U-shaped plate 3 on both sides of the buckle plate 4. The second U-shaped sleeves 13 and the first U-shaped sleeves 12 are detachably plugged with L-shaped elastic reinforcing plates 14. When the elastic performance of the U-shaped plate 3 decreases, the two ends of the elastic reinforcing plate 14 are respectively inserted into the first U-shaped sleeve 12 and the second U-shaped sleeve 13, thereby enhancing the elastic performance of the U-shaped plate 3 itself, so that the U-shaped plate 3 and the plug-in plate 1 are firmly clamped together.

[0027] The snap plate 4 is a T-shaped structure. The notch 5 and the limiting hole 6 on the snap plate 4 are staggered with the U-shaped plate 3 . The snap plate 4 presses down the plug 2 to prevent the plug 2 from falling off from the plug plate 1 .

[0028] A protective sleeve 15 is arranged inside the notch 5 and the limiting hole 6 to prevent the power cord of the plug 2 from being worn. The protective sleeve 15 is made of rubber and is fixed to the notch 5 and the limiting hole 6 by colloid bonding, which effectively avoids wearing the power cord of the plug 2.

[0029] Protection washers 16 are fixedly provided at both ends of the spring 9. The protection washers 16 are provided to prevent the ends of the spring 9 from directly contacting with the U-shaped plate 3 and the limiting circular plate 8 and causing wear.

[0030] Working principle: When in use, first pass the power cord on the plug 2 into the limiting hole 6 through the notch 5, plug the plug 2 into the socket on the plug board 1, move the snap plate 4 along the power cord of the plug 2, and buckle the U-shaped plate 3 on the plug board 1. At this time, the U-shaped plate 3 moves downward along the movable rod 7 relative to the snap plate 4 to compress the spring 9, and the clamping block 10 enters the inside of the clamping groove 11, thereby installing the U-shaped plate 3 on the plug board 1. The snap plate 4 is pulled downward by the movable rod 7 to fix the plug 2, preventing the plug 2 from shaking on the plug board 1 and preventing the plug 2 from falling off from the socket, thereby ensuring the stability of the power input of the electrical equipment.
