Description

Technical Field

[0001] This utility model relates to the field of battery testing clamp technology, and in particular to a battery testing clamp. Background Technology

[0002] Battery test clamps are key components connecting batteries to testers. They are mainly used to transmit electrical signals to detect parameters such as battery voltage, internal resistance, and capacity. However, when using test clamps, if the test environment is too cramped to fit a hand, or if the space is too small after the battery pack is installed, test safety cannot be guaranteed and testing cannot be performed. Furthermore, when the clamps are not in use, the ends of the clamps are always exposed, which makes them susceptible to damage. Utility Model Content

[0003] The main purpose of this utility model is to provide a battery testing clamp that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A battery testing clamp includes a first clamp rod and a second clamp rod. The second clamp rod is movably mounted on one side of the first clamp rod. A fixing sleeve is fixedly mounted on the upper and lower surfaces of the first clamp rod near its front end. A baffle is movably mounted on one side surface of the front end of the first and second clamp rods. An extension rod is fixedly mounted on the fixing sleeve. Wires are installed inside the first and second clamp rods. A push-pull component is movably mounted on the extension rod. A handle is movably mounted on the rear end of the extension rod.

[0006] More preferably, the front end of the extension rod has an opening, the rear end of the extension rod has an embedding groove, the upper and lower surfaces of the embedding groove have limiting grooves, and the upper surface of the extension rod has positioning holes on both sides above the front and rear ends of the embedding groove.

[0007] More preferably, a slider is fixedly installed on the rear surface of the baffle, and a groove is opened on one side surface of the front end of the first clamping rod and the second clamping rod, and the slider is embedded in the groove.

[0008] More preferably, the push-pull component includes a rectangular sleeve, a connecting plate, a sliding sleeve, and a locking block. The connecting plate is fixedly installed on the rear surface of the rectangular sleeve, both above and below it. The sliding sleeve is fixedly installed on the rear surface of the connecting plate, and the locking block is fixedly installed inside the sliding sleeve.

[0009] More preferably, the handle has a retaining groove inside, the rear end of the handle has a rod groove inside, a guide rod is fixedly installed inside the rod groove, a spring is sleeved on the surface of the guide rod, a limiting slider embedded in the limiting groove is fixedly installed on the upper and lower surfaces of the rear end of the handle, a pressing block is sleeved on the surface of the guide rod above the spring, and a plug is fixedly installed on the upper surface of the pressing block near both ends.

[0010] In a further preferred embodiment, the upper end of the insertion rod passes through the handle and is embedded in the positioning hole, and the locking block passes through the retaining groove.

[0011] Compared with the prior art, this utility model proposes a battery testing clamp, which has the following beneficial effects:

[0012] In this invention, by setting an extension rod, a baffle, a push-pull component, and a handle in a cooperative manner, when the pressing block on the handle is pressed down, the insertion rod can be disengaged from the positioning hole. This allows the handle to be pushed into or pulled out of the positioning groove by a certain length. Under the action of the spring, the pressing block causes the insertion rod to be embedded in another positioning hole. Then, by pulling the push-pull component, the rectangular sleeve moves towards the rear end of the first and second clamping rods. When the push-pull component moves, the rectangular sleeve can be used to open the first and second clamping rods. Then, the push-pull component is moved back to its original position. This allows the wire clamp to be held on the battery electrodes even in places where it is not possible to reach by hand. The baffle can protect the ends of the first and second clamping rods when they are not in use. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figure 1-4 As shown, a battery testing clamp includes a first clamp rod 1 and a second clamp rod 2. The second clamp rod 2 is movably installed on one side of the first clamp rod 1. A fixing sleeve 3 is fixedly installed on the upper and lower surfaces of the first clamp rod 1 near the front end. A baffle 5 is movably installed on one side surface of the front end of the first clamp rod 1 and the second clamp rod 2. An extension rod 4 is fixedly installed on the fixing sleeve 3. A wire 6 is installed inside the first clamp rod 1 and the second clamp rod 2. A push-pull component 7 is movably sleeved on the extension rod 4. A handle 8 is movably installed at the rear end of the extension rod 4.

[0022] In a preferred embodiment: the front end of the extension rod 4 has an opening 401, the rear end of the extension rod 4 has an embedding groove 402, the upper and lower surfaces of the embedding groove 402 have limiting grooves 404, and the upper surface of the extension rod 4 has positioning holes 403 on both sides above the front and rear ends of the embedding groove 402.

[0023] In the above structure, during the opening process of clamp rod 1 and clamp rod 2, the opening 401 can accommodate clamp rod 1 and clamp rod 2 when they are unfolded, and a torsion spring is provided between clamp rod 1 and clamp rod 2, so that clamp rod 1 and clamp rod 2 can be stably clamped on the battery electrodes.

[0024] In a preferred embodiment: a slider is fixedly installed on the rear surface of the baffle 5, and a groove 201 is opened on one side of the front end of the first clamp rod 1 and the second clamp rod 2, and the slider is embedded in the groove 201.

[0025] In the above structure, there is a certain friction between the slider and the groove 201, and the coefficient of friction must ensure that the baffle 5 will not move without a large external force.

[0026] In a preferred embodiment, the push-pull member 7 includes a rectangular sleeve 702, a connecting plate 703, a sliding sleeve 701, and a locking block 704. The connecting plate 703 is fixedly installed on the rear surface of the rectangular sleeve 702, both above and below it. The sliding sleeve 701 is fixedly installed on the rear surface of the connecting plate 703. The locking block 704 is fixedly installed inside the sliding sleeve 701.

[0027] In the above structure, when the push-pull member 7 is moved toward the rear end of the first clamp 1 and the second clamp 2, the rectangular sleeve 702 can open the first clamp 1 and the second clamp 2. Since the locking block 704 passes through the stop groove 801, the push-pull member 7 can always be connected to the handle 8.

[0028] In a preferred embodiment: a retaining groove 801 is provided inside the handle 8, a rod groove 802 is provided inside the rear end of the handle 8, a guide rod 803 is fixedly installed inside the rod groove 802, a spring 804 is sleeved on the surface of the guide rod 803, a limiting slider 805 embedded in the limiting groove 404 is fixedly installed on the upper and lower surfaces of the rear end of the handle 8, a pressing block 806 is sleeved on the surface of the guide rod 803 above the spring 804, and an insert rod 807 is fixedly installed on the upper surface of the pressing block 806 near both ends.

[0029] In the above structure, the spring 804 is in an extended state in its natural state, and the elastic coefficient of the spring 804 must ensure that the pressing block 806 will not cause the insertion rod 807 to exit from the positioning hole 403 without a certain downward external force.

[0030] In a preferred embodiment: the upper end of the insertion rod 807 passes through the handle 8 and is embedded in the positioning hole 403, and the locking block 704 passes through the retaining groove 801.

[0031] In the above structure, the engagement of the insertion rod 807 with the positioning holes 403 at different positions can position the length of the handle 8.

[0032] In use, by pressing down on the pressing block 806 on the handle 8, the insertion rod 807 can be disengaged from the positioning hole 403. This allows the handle 8 to be pushed into or pulled out of the insertion groove 402 by a certain length. Under the action of the spring 804, the pressing block 806 causes the insertion rod 807 to be inserted into another positioning hole 403. Then, by pulling the push-pull member 7, the rectangular sleeve 702 moves towards the rear end of the first clamping rod 1 and the second clamping rod 2. When the push-pull member 7 moves... The rectangular sleeve 702 can be used to open the first clamp 1 and the second clamp 2. Then, the push-pull piece 7 can be moved back to its original position. At this time, the first clamp 1 and the second clamp 2 will close under the action of the torsion spring. This allows the wire clamp to be clamped on the battery electrode even in places where the hand cannot reach. When the wire clamp is not in use, the stop block 5 can be moved so that the extension length of the stop block 5 is greater than the ends of the first clamp 1 and the second clamp 2. This prevents the ends of the first clamp 1 and the second clamp 2 from being damaged by collision with foreign objects.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
