Description

Technical Field

[0001] This utility model belongs to the technical field of alligator clip test terminals, and specifically relates to an adjustable alligator clip test terminal. Background Technology

[0002] Alligator clip test terminals, commonly referred to simply as alligator clips, are connection tools widely used in the fields of electronics and electrical engineering. They are named for their shape, which resembles an alligator's mouth. One end is a metal clip that can open and close, while the other end typically has a connector with wires for connecting measuring instruments such as multimeters and oscilloscopes.

[0003] Problems with existing technology:

[0004] Currently, existing alligator clip test terminals cannot be adjusted in size to accommodate different sizes of objects being clamped, thus affecting their practicality. Furthermore, the clamping force of existing alligator clips cannot be adjusted during use, which can easily damage fragile components. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable alligator clip test terminal, which can adjust the clamping force of the alligator clip through an adjustable support mechanism, thereby avoiding damage when connecting fragile components. At the same time, the linkage between the support mechanism and the adjustment mechanism allows the pressing handle to adjust the angle, so that the opening and closing width of the lower and upper clamping plates can be adjusted according to the different sizes of the objects being clamped.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An adjustable alligator clip test terminal includes a lower clamp plate, and an upper clamp plate is rotatably mounted on the top of the lower clamp plate via a pivot.

[0008] The lower clamping plate is provided with a support mechanism inside, and one end of the upper clamping plate is provided with an adjustment mechanism;

[0009] The adjustment mechanism includes a limiting component, which pushes the mounting rod to drive the locking block to move linearly, so that the locking block engages with the locking tooth seat.

[0010] The upper clamping plate is hinged to the pressing handle, the top of the support mechanism is fixedly installed to the upper clamping plate, and the rotating shaft passes through the lower clamping plate and the upper clamping plate.

[0011] The mounting rod is slidably mounted to the pressing handle, and two sets of corresponding locking blocks and locking tooth seats are provided. The locking blocks are fixedly mounted on the outer surface of the mounting rod.

[0012] The limiting component includes a through groove, a limiting seat is slidably mounted on the through groove, and a second spring abuts against one side of the limiting seat.

[0013] The through groove passes through the upper clamping plate, and the second spring pushes the limiting seat to abut against the mounting rod.

[0014] The support mechanism includes an upper fixed seat, the bottom of which is abutted against a lower fixed seat by a first spring, and an adjusting bolt is rotatably mounted on the bottom of the lower fixed seat.

[0015] The upper fixed seat is fixedly installed with the upper clamping plate, and the adjusting bolt is threaded inside the lower clamping plate.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention utilizes a through groove inside the pressing handle, where a second spring installed can push a limiting seat to move the mounting rod. This causes the mounting rod to engage with the locking block and locking tooth seat, thus limiting the pressing handle and the upper clamping plate. By pushing the mounting rod to one side, the limiting of the locking tooth seat can be released, allowing the angle between the pressing handle and the upper clamping plate to be adjusted under the action of the hinge. This, in conjunction with the support mechanism, enables the adjustment of the unfolded width of the lower and upper clamping plates, making it suitable for clamping objects of different sizes.

[0018] This utility model features an upper fixed seat fixedly installed inside the upper clamping plate. The upper fixed seat abuts against the lower fixed seat via a first spring. An adjusting bolt rotatably installed at the bottom of the lower fixed seat is threaded onto the lower clamping plate. Therefore, when the adjusting bolt is rotated, the elastic strength of the first spring can be adjusted, thereby adjusting the clamping force generated by the lower clamping plate and the upper clamping plate, thus preventing damage to fragile components during clamping.

Detailed Implementation

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-4 As shown, an adjustable alligator clip test terminal includes a lower clamp 1, and an upper clamp 3 is rotatably mounted on the top of the lower clamp 1 via a rotating shaft 2.

[0027] The lower clamping plate 1 is equipped with a support mechanism 4 inside, and the upper clamping plate 3 is equipped with an adjustment mechanism 7 at one end;

[0028] The adjustment mechanism 7 includes a limiting component 74, which pushes the mounting rod 72 to drive the locking block 73 to move linearly, so that the locking block 73 engages with the locking tooth seat 71.

[0029] See attached document Figure 1 , Figure 2 and Figure 3 In this embodiment, a hinge 5 is hinged between the upper clamping plate 3 and the pressing handle 6, the top of the support mechanism 4 is fixedly installed with the upper clamping plate 3, and the rotating shaft 2 passes through the lower clamping plate 1 and the upper clamping plate 3.

[0030] In the above embodiment, the angle between the upper clamping plate 3 and the pressing handle 6 can be adjusted by the action of the hinge 5, thereby adjusting the pressing depth of the upper clamping plate 3 synchronously, and thus adjusting the unfolding width of the lower clamping plate 1 and the rotating shaft 2.

[0031] Furthermore, an installation rod 72 is slidably installed inside the pressing handle 6, and two sets of locking blocks 73 and locking tooth seats 71 are provided accordingly. The locking blocks 73 are fixedly installed on the outer surface of the installation rod 72. Therefore, when the limiting component 74 drives the installation rod 72 to move, the locking blocks 73 can engage with the locking tooth seats 71, thereby fixing the connection between the upper clamping plate 3 and the pressing handle 6.

[0032] Specifically, the limiting component 74 includes a through groove 741, wherein a limiting seat 742 is slidably mounted on the through groove 741, and a second spring 743 is abutted on one side of the limiting seat 742.

[0033] According to the above structure, the through groove 741 passes through the upper clamping plate 3, and the second spring 743 abuts between the through groove 741 and the limiting seat 742. Therefore, the limiting seat 742 can be pushed by the second spring 743 to abut against the mounting rod 72, so that the locking block 73 and the locking tooth seat 71 can be locked. The limiting of the locking tooth seat 71 can be released by manually moving the mounting rod 72 in the opposite direction, so that the angle between the upper clamping plate 3 and the pressing handle 6 can be adjusted. By releasing the mounting rod 72, the locking block 73 can be reset by the second spring 743 and locked against the locking tooth seat 71.

[0034] See attached document Figure 1 and Figure 4 In this embodiment, the support mechanism 4 includes an upper fixed seat 41, the bottom of the upper fixed seat 41 abuts against a lower fixed seat 43 via a first spring 42, and an adjusting bolt 44 is rotatably mounted on the bottom of the lower fixed seat 43.

[0035] In the above embodiment, the upper fixed seat 41 is fixedly installed with the upper clamping plate 3, and the adjusting bolt 44 is threaded inside the lower clamping plate 1. Therefore, when the adjusting bolt 44 is rotated, the height of the lower fixed seat 43 can be adjusted. In this way, with the cooperation of the first spring 42, the softness and hardness of the first spring 42 can be adjusted, thereby realizing the adjustment of the clamping force between the upper clamping plate 3 and the lower clamping plate 1, thus avoiding damage to fragile components.

[0036] The working principle of this utility model is as follows: When in use, the adjusting bolt 44 can be rotated to push the lower fixed seat 43 to move vertically according to the different components. Since the upper fixed seat 41 is fixed, the softness and hardness of the first spring 42 can be adjusted under the clamping of the upper fixed seat 41 and the lower fixed seat 43, thereby adjusting the clamping force of the upper clamping plate 3 and the lower clamping plate 1. When the clamped component is too large, the mounting rod 72 can be pushed to one side to compress the second spring 743 by the limiting seat 742. The movement of the mounting rod 72 can release the limiting block 73 on the toothed seat 71. Then, under the action of the hinge 5, the angle between the upper clamping plate 3 and the pressing handle 6 is adjusted, and the softness and hardness of the support mechanism 4 are adjusted accordingly. The mounting rod 72 can be released. After the second spring 743 is reset, the limiting seat 742 pushes the mounting rod 72 to drive the locking block 73 to engage with the toothed seat 71. Then, the hinge 5 can be opened by pressing the pressing handle 6.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
