The bolts of the multi-way connector for extending the positive and negative terminals of the battery of the utility model can be connected to multiple high-current wires, and have strong expansibility. It can not only meet the connection of the positive and negative wires of the whole vehicle electrical equipment to the positive and negative terminals of the battery, but also meet the connection of the positive and negative wires of the high-current electrical equipment of the modified vehicle (for example: oil and gas spring control motor, auxiliary starting socket, three-proof motor) to the positive and negative terminals of the battery, and has the characteristics of small size, easy assembly, strong expansibility, etc. In actual use, the above patent is prone to dust accumulation at its interface, which has defects.

[0004] Most of the existing multi-way connector charging piles are exposed on the surface, and some of the charging piles are not used during use, resulting in their interfaces being exposed to the outside. After a period of time, dust and particles in the air may accumulate at the interfaces, thus affecting subsequent normal operation, so they need to be improved. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a multi-way connector for extending the power terminal of an alarm, which has the advantage of preventing dust from accumulating when the interface is exposed and not in use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-way connector for extending the power terminal of an alarm, comprising a base, both ends of the top of the base are movably connected with a first baffle, the first baffle is internally movably connected with a second baffle, a plurality of electric piles are arranged on the top of the base, the base is internally movably connected with a gear, a first tooth plate and a second tooth plate, one end of the first tooth plate is fixedly connected with a limiting rod, a straight groove is provided on the surface of the limiting rod in an annular shape of 180 degrees, a push rod is internally movably connected with the limiting rod, a moving block is internally movably connected with the base, sliding grooves are provided on both sides of the moving block, and a third tooth plate matching the sliding groove is fixedly connected inside the base.

[0007] Preferably, one end of the push rod is fixedly connected to a spring fixed to the first tooth plate, and the spring is used to squeeze the push rod and keep the push rod moving toward the outside of the base.

[0008] Preferably, two tooth blocks are arranged on the top of the slide groove, and the tooth blocks are meshed with the third tooth plate in an initial state.

[0009] Preferably, the limiting rod and the push rod both penetrate the outer wall of the base and extend to the outside of the base, and one end of the push rod is provided with a convex rod movable inside the straight slot at an annular equiangular shape.

[0010] Preferably, the convex rod is movably engaged in the interior of the slide groove, and when the push rod moves toward the interior of the base, it drives the convex rod to slide in the interior of the slide groove and drives the moving block to move downward.

[0011] Preferably, the upper and lower ends of the gear are respectively meshed with the bottom of the second tooth plate and the top of the first tooth plate, and the tops of the first tooth plate and the second tooth plate are both provided with protrusions, which pass through the top of the base and extend to the outside of the base.

[0012] Preferably, the end of the push rod located outside the base is made of rubber.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

While the first tooth plate and the second tooth plate move, the two second baffles are driven to move in the opposite direction, so that the second baffle is retracted to the inside of the first baffle. When the operator needs to use multiple electric piles, the push rod continues to move. When the second baffle abuts against the inner wall of the first baffle, the first baffle drives the two second baffles to move in the opposite direction, thereby releasing the seal of the electric pile, thereby preventing the interface of a part of the electric pile from being exposed to the outside when it is not used, and dust and particles in the air may accumulate at the interface, affecting the subsequent normal use.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0022] like Figures 1 to 5As shown, the utility model provides a multi-way connector for extending the power terminal of an alarm, including a base 1, both ends of the top of the base 1 are movably connected with a first baffle 2, the first baffle 2 is movably connected inside with a second baffle 3, a plurality of electric piles 4 are arranged on the top of the base 1, a gear 5, a first tooth plate 6 and a second tooth plate 7 are movably connected inside the base 1, one end of the first tooth plate 6 is fixedly connected to a limit rod 8, a straight groove 9 is provided on the surface of the limit rod 8 in an annular manner at 180 degrees, a push rod 10 is movably connected inside the limit rod 8, a moving block 11 is movably connected inside the base 1, both sides of the moving block 11 are provided with slide grooves 12, and the base 1 is fixedly connected inside with a third tooth plate 13 matching the slide groove 12.

[0023] The above scheme is adopted: the push rod 10 is pressed toward the inside of the base 1, driving the protrusion to slide along the track of the slide groove 12, causing the moving block 11 to move downward, and when the protrusion moves to the top of the slide groove 12, the tooth block at the top of the moving block 11 is disengaged from the third tooth plate 13, and the first tooth plate 6 is driven to move in the direction of the gear 5 through the limit rod 8. When the second tooth plate 7 moves, it drives the two second baffles 3 to move in the opposite direction. If multiple electric piles 4 are needed, continue to move the push rod 10. When the second baffle 3 abuts against the inner wall of the first baffle 2, the first baffle 2 drives the two second baffles 3 to move in the opposite direction, thereby releasing the seal of the electric pile 4.

[0024] like Figure 5 As shown, one end of the push rod 10 is fixedly connected to a spring 14 fixed to the first tooth plate 6, and the spring 14 is used to squeeze the push rod 10 and keep the push rod 10 moving toward the outside of the base 1. Two tooth blocks are arranged on the top of the slide groove 12, and the tooth blocks are engaged with the third tooth plate 13 in the initial state.

[0025] With the above solution, the protrusion slides along the track of the slide slot 12, driving the moving block 11 downward through the slide slot 12, and moving to the top of the slide slot 12, the tooth block at the top of the moving block 11 and the third tooth plate 13 will be released from the engaging state.

[0026] like Figure 1 and Figure 5 As shown, the limiting rod 8 and the push rod 10 both penetrate the outer wall of the base 1 and extend to the outside of the base 1 . A protruding rod movable in the straight slot 9 is provided at one end of the push rod 10 in an annular and equiangular manner.

[0027] like Figure 2 and Figure 4As shown, the convex rod is movably engaged in the inside of the slide groove 12. When the push rod 10 moves toward the inside of the base 1, it drives the convex rod to slide in the inside of the slide groove 12 and drives the moving block 11 to move downward. The upper and lower ends of the gear 5 are respectively engaged with the bottom of the second tooth plate 7 and the top of the first tooth plate 6. The tops of the first tooth plate 6 and the second tooth plate 7 are both provided with convex blocks, which pass through the top of the base 1 and extend to the outside of the base 1.

[0028] like Figure 5 As shown, one end of the push rod 10 located outside the base 1 is made of rubber.

[0029] The above solution is adopted: through the limitation of rubber material, rubber has softness and deformation properties, which makes the operator more comfortable when using it.

[0030] The working principle and use process of this utility model: Figure 2 For example, the first tooth plate 6 is marked on the left and the second tooth plate 7 is marked on the right. The operator presses the push rod 10 toward the inside of the base 1, thereby driving the protrusion to slide along the trajectory of the slide groove 12, and then driving the moving block 11 to move down through the slide groove 12. When the protrusion moves to the top of the slide groove 12, the tooth block at the top of the moving block 11 is disengaged from the third tooth plate 13. Subsequently, the operator moves the push rod 10, thereby driving the first tooth plate 6 to move in the direction of the gear 5 through the limit rod 8. While the first tooth plate 6 moves, it drives the gear 5 to rotate, thereby driving the second tooth plate 7 to move toward the first tooth plate 6 through the gear 5. While the first tooth plate 6 and the second tooth plate 7 move, they drive the two second baffles 3 to move in the opposite direction, thereby shrinking the second baffle 3 to the inside of the first baffle 2. When the operator needs to use multiple electric piles 4, he continues to move the push rod 10. When the second baffle 3 abuts against the inner wall of the first baffle 2, the first baffle 2 drives the two second baffles 3 to move in the opposite direction, thereby releasing the seal of the electric pile 4.
