Description

Technical Field

[0001] This utility model belongs to the field of automotive starter clip technology, and in particular to an automotive starter clip with insert teeth. Background Technology

[0002] In the field of emergency car starting, car starter clips are the core components for achieving temporary conductive connection of the battery. Their structure is usually composed of a plastic clip body and a metal conductive component. The small metal teeth are the key contact parts of the metal conductive component. Their main function is to enhance the friction between the clip body and the battery terminals, prevent slippage during clamping, and help improve the stability of current conduction.

[0003] For example, a Chinese patent for a battery starter clip, patent number CN203950861U, includes two mating gripping parts. One end of each gripping part is fixed with a biting part, and the biting part is connected to the gripping part via an elastic shaft. The biting part includes mating large teeth and small teeth, which are respectively fixedly connected to one end of the two gripping parts. In the assembly process of the car starter clip between the small teeth and the plastic clip body, a screw-fixed connection method is commonly used: mounting holes must first be pre-drilled in the plastic clip body, then the small metal teeth are aligned with the holes and tightened with screws. This assembly method requires precise alignment of the holes and screws, making the operation cumbersome. Especially in mass production scenarios, alignment deviations can easily lead to low assembly efficiency and increased labor costs. Furthermore, during long-term use, the plastic clip body may undergo slight deformation due to temperature changes or vibrations, leading to loosening of the screws, affecting the contact stability between the small teeth and the battery terminals, and even posing a risk of conductive failure. Utility Model Content

[0004] In view of this, the present invention provides an automotive starter clamp with insert teeth that can reduce processing costs to meet industrial needs.

[0005] A car starter clip with insert teeth includes an upper clip assembly and a lower clip assembly rotatably connected to one side of the upper clip. The upper clip includes an upper clip body, a limiting groove disposed on one side of the upper clip body, and a small tooth embedded in the limiting groove. The small tooth is fixedly housed in the limiting groove, and the outer contour shape of the small tooth is consistent with that of the limiting groove.

[0006] Furthermore, the height of the small tooth is greater than the depth of the limiting groove.

[0007] Furthermore, the outer contours of the small teeth and the limiting groove are both U-shaped.

[0008] Furthermore, the small tooth and the limiting groove are in an interference fit.

[0009] Furthermore, the upper clamp also includes at least one clamp positioning groove disposed on one side edge of the upper clamp body.

[0010] Furthermore, the small tooth includes a small tooth body and at least one tooth positioning groove disposed on one side edge of the small tooth body. The tooth positioning groove and the clamping body positioning groove are both facing the same side on the upper clamping body and correspond to each other.

[0011] Furthermore, the lower clamp includes a lower clamp body, a large tooth fixedly connected to one side of the lower clamp body, and a wire fixedly connected to one end of the large tooth.

[0012] Furthermore, the large tooth includes a large tooth body and at least one large tooth clamping groove disposed on one side of the large tooth body.

[0013] Furthermore, anti-slip serrations are provided on the side walls of both the upper and lower clamping bodies.

[0014] Compared with existing technologies, the car starter clip with insert teeth provided by this utility model utilizes the upper clamp assembly. The small teeth are embedded in the limiting groove of the upper clamp body, and the small teeth are fixedly connected to the upper clamp body. The limiting groove is used to accommodate the small teeth, and the small teeth are fixedly accommodated within the limiting groove. The limiting groove and the outer contour shape of the small teeth are consistent, thus ensuring the stable position of the small teeth within the limiting groove. It can be seen that this car starter clip with insert teeth enables rapid assembly of the small teeth and the upper clamp body, reducing processing costs and improving production efficiency.

[0018] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0019] like Figures 1 to 3The diagram shows a schematic of the structure of the car starter clip with insert teeth provided by this utility model. The car starter clip with insert teeth includes an upper clamping assembly 10 and a lower clamping assembly 20 disposed on one side of the upper clamping assembly 10. The car starter clip with insert teeth also includes other functional modules, such as assembly components, torsion springs (not shown), etc., which should be known to those skilled in the art and will not be described in detail here.

[0020] The upper clamping assembly 10 includes an upper clamping body 11, a limiting groove 12 disposed on one side of the upper clamping body 11, a small tooth 13 embedded in the limiting groove 12, and at least one clamping body positioning groove 14 disposed on one side edge of the upper clamping body 11.

[0021] The upper clamp 11 is the handheld operating part of the starter clamp. The user can open and close the upper clamp 11 and the lower clamp assembly 20 by pressing on the upper clamp 11. In addition, the upper clamp 11 is made of plastic, which ensures the insulation performance of the upper clamp 11.

[0022] The limiting groove 12 is used to accommodate the small tooth 13. The small tooth 13 is fixedly accommodated within the limiting groove 12. The outer contour shape of the limiting groove 12 and the small tooth 13 is consistent, so the small tooth 13 is stably positioned within the limiting groove 12. In this embodiment, the outer contours of both the small tooth 13 and the limiting groove 12 are U-shaped. The fixed connection between the small tooth 13 and the limiting groove 12 can be either an interference fit or synchronous injection molding. When the fixed connection between the small tooth 13 and the limiting groove 12 is an interference fit, the user presses the small tooth 13 into the limiting groove 12 using the equipment, thereby achieving a fixed connection between the small tooth 13 and the upper clamp 11. In this embodiment, the upper clamping body 11 and the small teeth 13 are simultaneously placed into the injection mold, thereby forming the upper clamping body 11 and the small teeth 13 simultaneously, forming a whole. During the formation of the upper clamping body 11 and the small teeth 13, the limiting groove 12 is also formed on the upper clamping body 11. It can be seen that the small teeth 13 are fixedly embedded in the limiting groove 12, realizing the rapid assembly of the small teeth 13 and the upper clamping body 11, reducing processing costs and improving production efficiency.

[0023] The height of the small tooth 13 is greater than the depth of the limiting groove 12, so that the small tooth 13 protrudes from one side of the upper clamping body 11, thereby facilitating the clamping of the small tooth 13.

[0024] The small tooth 13 includes a small tooth body 131 and at least one tooth positioning groove 132 disposed on one side edge of the small tooth body 131. The tooth positioning groove 132 and the clamping body positioning groove 14 both face the same side of the upper clamping body 11 and correspond to each other. Both the tooth positioning groove 132 and the clamping body positioning groove 14 are used to accommodate the workpiece. Since the height of the small tooth 13 is greater than the depth of the limiting groove 12, the tooth positioning groove 132 and the clamping body positioning groove 14 are stepped, so that the workpiece forms a stepped limiting within the tooth positioning groove 132 and the clamping body positioning groove 14. This achieves basic positioning of the bottom of the workpiece through the clamping body positioning groove 14, and the tooth positioning groove 132 provides secondary constraint on the workpiece, preventing lateral displacement of the workpiece during assembly and use. Furthermore, during the use of the starting clamp, since the starting time is only about 10 seconds when starting the vehicle, the small tooth 13 does not generate significant heat and will not affect the normal use of the starting clamp.

[0025] The lower clamp assembly 20 includes a lower clamp body 21, a large tooth 22 fixedly connected to one side of the lower clamp body 21, and a wire 23 fixedly connected to one end of the large tooth 22.

[0026] The lower clamp 21 is rotatably connected to the upper clamp 11. In this embodiment, the upper clamp 11 is provided with a limiting pin, and the lower clamp 21 is provided with a limiting hole. The limiting pin is inserted into the limiting hole, thereby realizing the rotatable connection between the lower clamp 21 and the upper clamp 11. The rotatable connection method between the lower clamp 21 and the upper clamp 11 is a prior art and will not be described in detail here.

[0027] The large tooth 22 includes a large tooth body 221 and at least one large tooth clamping groove 222 disposed on one side of the large tooth body 221. The large tooth clamping groove 222 is used to accommodate the workpiece to facilitate the stability of the large tooth 22 during the clamping process. Anti-slip teeth are provided on the side walls of the upper clamping body 11 and the lower clamping body 21 to increase the friction between the user and the upper clamping body 11 and the lower clamping body 21, thereby making the user hold the upper clamping body 11 and the lower clamping body 21 stably.

[0028] The large tooth 22 is fixedly connected to the lower clamping body 21. The connection between the large tooth 22 and the lower clamping body 21 can be either a screw connection or a snap-fit ​​connection. In this embodiment, the connection between the large tooth 22 and the lower clamping body 21 is a screw connection. Mounting holes are pre-set on both the large tooth 22 and the lower clamping body 21, and a screw passes through these mounting holes to achieve the connection between the large tooth 22 and the lower clamping body 21. This connection structure between the large tooth 22 and the lower clamping body 21 is existing technology and will not be described in detail here. Both the large tooth 22 and the small tooth 13 are made of metal to ensure the conductivity of the starting clamp.

[0029] The wire 23 is connected to one end of the large tooth 22. The wire 23 and one end of the large tooth 22 are interconnected to realize the conduction between the wire 23 and the large tooth 22. The connection structure between the wire 23 and the large tooth 22 is a prior art and will not be described in detail here.

[0030] A torsion spring is provided between the upper clamping assembly 10 and the lower clamping assembly 20. The clamping ends of the upper clamping assembly 10 and the lower clamping assembly 20 are automatically closed by the elasticity of the torsion spring. The structure in which the torsion spring is fixedly connected between the upper clamping assembly 10 and the lower clamping assembly 20 is a prior art and will not be described in detail here.

[0031] Compared with the prior art, the car starter clip with insert teeth provided by this utility model utilizes the upper clamp assembly 10. The small teeth are embedded in the limiting groove of the upper clamp body, and the small teeth are fixedly connected to the upper clamp body. The limiting groove 12 is used to accommodate the small teeth 13, which are fixedly accommodated within the limiting groove 12. The outer contour shape of the limiting groove 12 and the small teeth 13 are consistent, thus ensuring the stable position of the small teeth 13 within the limiting groove 12. It can be seen that this car starter clip with insert teeth enables rapid assembly of the small teeth 13 with the upper clamp body 11, reducing processing costs and improving production efficiency.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
