Description

Technical Field

[0001] This utility model relates to the field of emergency power starter clamp technology, and more specifically, to an emergency power starter clamp. Background Technology

[0002] An emergency jump starter clamp is a device used to connect an emergency jump starter to a device to be started (such as a car engine). Its function is to safely and quickly transfer electrical energy from the emergency jump starter to the vehicle's starting system in case the vehicle battery is dead or in other emergencies, helping to start the engine. It is a key component for the emergency jump starter to function, ensuring the reliability and safety of power transmission. In use, the clamp consists of two differently colored clamping arms that are attached to the positive and negative terminals of the battery, with the alligator-shaped metal chucks contacting the terminals. However, existing technology has the following shortcomings in its use:

[0003] After the chuck on the clamp arm is clamped onto the positive and negative terminals of the battery, the contact area between the chuck and the terminal is small. When the vehicle is started, the vehicle will vibrate, which may cause the chuck to detach from the terminal.

[0004] Therefore, there is an urgent need for an emergency power starter clamp to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problem that when the clamp on the clamp arm is clamped onto the positive and negative terminals of the battery, the contact area between the clamp and the terminal is small, which may cause the clamp to detach from the terminal when the vehicle is started due to vibration.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An emergency starter clamp is provided to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] An emergency power starter clamp includes a rotating shaft, on which a first clamping arm and a second clamping arm are rotatably sleeved. A torsion spring is provided on the outside of the rotating shaft. Both the first clamping arm and the second clamping arm have a plurality of arc-shaped grooves and arc-shaped openings arranged linearly and equidistantly. An arc-shaped chuck is slidably disposed in the arc-shaped groove. A limiting rod located in the arc-shaped opening is fixedly connected to one end face of the arc-shaped chuck.

[0010] As a preferred technical solution of this application, the two ends of the torsion spring are fixedly connected to the first clamping arm and the second clamping arm, respectively.

[0011] As a preferred technical solution of this application, both ends of the rotating shaft are fixedly connected to limit blocks, the limit blocks are in contact with the first clamping arm, the opposite two end faces of the second clamping arm are in contact with the first clamping arm, and the two limit blocks are symmetrically distributed about the central axis of the rotating shaft.

[0012] As a preferred technical solution of this application, both the gripping parts of the first clamping arm and the gripping parts of the second clamping arm are covered with anti-slip sleeves.

[0013] As a preferred technical solution of this application, the arc-shaped groove is connected to the arc-shaped opening, and the arc-shaped clamp is made of a conductive metal material.

[0014] As a preferred technical solution of this application, the first clamping arm and the second clamping arm are arranged opposite to each other.

[0015] As a preferred technical solution of this application, the first clamping arm and the second clamping arm are fitted together.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. By pressing the first and second clamping arms with your hands, the first and second clamping arms rotate in opposite directions. After placing the first and second clamping arms on the outside of the battery terminal, the force of the torsion spring causes multiple arc-shaped clamps to contact the terminal from different angles, making the clamping force more evenly distributed on the surface of the terminal. This reduces the risk of the first and second clamping arms loosening due to vibration or pulling, and achieves a better anti-detachment effect.

[0019] 2. Compared to fixed traditional chucks, multiple movable arc-shaped chucks apply gentler pressure to the electrode surface during clamping, reducing scratches and wear caused by hard compression and effectively protecting the metal layer on the electrode surface.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] Example:

[0029] like Figure 1-4 As shown, the emergency start-up power supply clamp proposed in this embodiment includes a rotating shaft 1, on which a first clamping arm 2 and a second clamping arm 3 are rotatably sleeved. The first clamping arm 2 and the second clamping arm 3 are arranged opposite to each other and are in contact with each other. A torsion spring 4 is provided on the outside of the rotating shaft 1. The two ends of the torsion spring 4 are fixedly connected to the first clamping arm 2 and the second clamping arm 3 respectively. Both the first clamping arm 2 and the second clamping arm 3 are provided with a plurality of arc-shaped grooves 5 and arc-shaped openings 6 arranged linearly and equally spaced. An arc-shaped clamp 7 is slidably arranged in the arc-shaped grooves 5. A limiting rod 8 located in the arc-shaped opening 6 is fixedly connected to one end face of the arc-shaped clamp 7. The arc-shaped grooves 5 and the arc-shaped openings 6 are connected. The arc-shaped clamp 7 is made of a metal conductive material.

[0030] The operator holds the first clamping arm 2 and the second clamping arm 3 in their hand and applies force to them, causing them to rotate in opposite directions. This positions the first clamping arms 2 and 3 outside the battery terminal, placing multiple arc-shaped clamps 7 also outside the terminal. The operator then removes the force applied to the first clamping arms 2 and 3. Under the action of the torsion spring 4, the first clamping arms 2 and 3 rotate back. Simultaneously, when multiple arc-shaped clamps 7 in different positions contact the terminal, they rotate at a certain angle within the arc-shaped groove 5. The limiting rod 8 is positioned at the arc-shaped opening 6. The internal sliding mechanism allows multiple curved clamps 7 to better contact the terminal post from multiple different angles, making the clamping force more evenly distributed on the terminal post surface. This reduces the risk of the first clamp arm 2 and the second clamp arm 3 loosening due to vibration or pulling, resulting in a better anti-dislodgement effect. Compared with fixed traditional clamps, the multiple movable curved clamps 7 apply gentler pressure to the terminal post surface during clamping, reducing scratches or wear caused by hard compression and effectively protecting the metal layer on the terminal post surface. The movable curved clamps 7 can be flexibly adjusted in posture, making it easier to connect to the battery terminal post. They can adapt to battery terminal posts of different shapes, reducing the difficulty of operation.

[0031] like Figure 1 and Figure 2 As shown, both ends of the rotating shaft 1 are fixedly connected to limit blocks 9. The limit blocks 9 are in contact with the first clamping arm 2. The opposite two end faces of the second clamping arm 3 are in contact with the first clamping arm 2. The two limit blocks 9 are symmetrically distributed about the central axis of the rotating shaft 1.

[0032] By setting two limiting blocks 9, the first clamping arm 2 and the second clamping arm 3 can be prevented from sliding on the rotating shaft 1, and the first clamping arm 2 and the second clamping arm 3 can be limited.

[0033] like Figure 1 As shown, both the gripping parts of the first clamping arm 2 and the gripping parts of the second clamping arm 3 are fitted with anti-slip sleeves 10;

[0034] The anti-slip sleeve 10 is made of silicone, which has good flexibility and anti-slip performance. When the hand applies force to the first clamping arm 2 and the second clamping arm 3, the two anti-slip sleeves 10 can reduce the reaction force generated on the hand, reduce hand discomfort, and make it more comfortable to hold the first clamping arm 2 and the second clamping arm 3, which is beneficial to actual use.

[0035] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
