Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a circuit protection device for an in-vehicle distribution box, comprising a base 1 for supporting a distribution box 2, a support frame 10 for supporting a top cover 3 being fixedly connected to the top of the base 1, a top cover 3 for covering the top of the distribution box 2 being rotatably connected to the right end of the support frame 10, and the distribution box 2 can be prevented from moving up, down, left, and right by using the top cover 3 to block the top of the distribution box 2, a fixing component 6 for fixing the top cover 3 is provided at the left end of the support frame 10, a distribution box 2 is plugged into the top of the base 1, the distribution box 2 is a prior art, and can start working when the power is turned on, due to the prior art, this case will not be described in detail, a storage groove 9 for accommodating a moving wheel 24 is provided at the front end of the base 1, a limit assembly 7 for limiting the distribution box 2 from moving forward and backward is provided at the front end of the base 1, a roller 8 for squeezing the distribution box 2 is rotatably connected to the rear end of the top cover 3, and when the operator rotates to open the top cover 3, the top cover 3 will drive the roller 8 to rotate synchronously, and the roller 8 will push the distribution box 2 to move outward.

[0033] Reference Figure 1 - Figure 3 The distribution box 2 includes a box body 21 for protecting internal electronic components. A wiring port for connecting external wires is arranged at the top of the box body 21. The box body 21 is plugged into the top of the base 1. A box cover 25 for protecting the wiring port is rotatably connected to the top of the box body 21. By using the box cover 25 to cover the wiring port, the wiring port can be protected. An empty slot 23 for passing external lines is arranged at the top of the box body 21. A wire-receiving block 22 for fixing excess wires is fixedly connected to the bottom end of the box cover 25. The wire-receiving block 22 is a circular plastic buckle with an opening at the right end and has elastic deformation ability. When the wires are connected to the wiring port, the wire body can be clamped inside the wire-receiving block 22, and then the box cover 25 can be rotated to close, and the wires can be connected to the outside through the empty slot 23. A moving wheel 24 for driving the box body 21 to move is installed at the bottom end of the box body 21.

[0034] Reference Figure 4 - Figure 5The storage slot 9 and the moving wheel 24 are adapted. When the distribution box 2 is plugged into the top of the base 1, the moving wheel 24 will slide into the storage slot 9, and at this time the moving wheel 24 cannot contact the bottom of the storage slot 9. The fixing assembly 6 includes a rotating shaft 61 for limiting the rotation of the top cover 3. The right end of the rotating shaft 61 is fixedly connected to the left end of the top cover 3. When the top cover 3 rotates, it will drive the rotating shaft 61 to rotate synchronously. The rotating shaft 61 penetrates and is rotatably connected to the left end of the support frame 10. The rotating shaft 61 The left end of the support frame 10 is hinged with a stopper 62 for limiting the rotation of the rotating shaft 61. The left end of the support frame 10 is fixedly connected with a fixing block 63 for accommodating the stopper 62. When the stopper 62 is inserted into the fixing block 63, the rotating shaft 61 will be fixed and cannot rotate. The left end of the rotating shaft 61 is fixedly connected with a rubber block 64. The rubber block 64 is made of rubber material and has elastic deformation ability. When the operator does not move the stopper 62, the rubber block 64 will squeeze the stopper 62 to keep it fixed.

[0035] Reference Figure 4 The support frame 10 is set to be L-shaped, and multiple groups of fixed blocks 63 are provided. Another group of fixed blocks 63 is arranged at the left end of the L-shaped horizontal part of the support frame 10. When the top cover 3 is rotated to open, the fixed block 63 of the horizontal part of the support frame 10 can also be used to fix the stopper 62. The limit assembly 7 includes a block 71 for blocking the distribution box 2. The block 71 passes through and slides on the top of the base 1. By using the block 71 to block the front end of the distribution box 2, the distribution box 2 can be prevented from moving left and right. The front end of the block 71 is fixedly connected to a pedal 72 for driving the block 71 to move up and down. The pedal 72 passes through and slides on the front end of the base 1.

[0036] Reference Figure 4 The bottom end of the block 71 is fixedly connected with a limit spring 73 for driving the block 71 to move upward and reset. The bottom end of the limit spring 73 is fixedly connected to the inner wall of the base 1. The top of the base 1 is fixedly connected with a guide block 4 for driving the distribution box 2 to move upward and away from the ground. The left end of the distribution box 2 is fixedly connected with a slider 5 for directly contacting the guide block 4. The guide block 4 and the slider 5 are adapted to each other. The guide block 4 and the slider 5 are both set to a right-angle trapezoid, and the inclined surfaces of the two correspond to each other. When the distribution box 2 is pushed to move toward the top of the base 1, the guide block 4 will squeeze the slider 5 to force the slider 5 to drive the distribution box 2 to move upward. When the slider 5 moves to the top of the guide block 4, the distribution box 2 will drive the moving wheel 24 to move upward and away from the bottom end of the inner wall of the storage groove 9.

[0037] Working principle: During use, when the distribution box 2 needs to be taken out, the block 62 can be pushed upward to rotate it upward and disengage from the inside of the fixed block 63, and then the pedal 72 can be stepped on to drive the block 71 to move downward and disengage from the right end of the distribution box 2. At this time, the top cover 3 can be rotated, and the top cover 3 will drive the roller 8 to rotate synchronously. The roller 8 will squeeze the left end of the distribution box 2 and force the distribution box 2 to move outward. The distribution box 2 will be squeezed and move outward along the top of the guide block 4 under the guidance of the slider 5. During the movement, the moving wheel 24 will gradually re-ground, so that the distribution box 2 can resume its mobility.

[0038] After taking out the distribution box 2, the box cover 25 can be rotated open to expose the wiring port, and then the wires can be used to connect the wiring port and the electrical equipment. After the connection is completed, the wire body can be fixed with the wire take-up block 22, and the box cover 25 can be rotated closed again to achieve the effect of protecting the connection.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
