Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and more specifically, to a novel caliper sliding structure. Background Technology

[0002] In length measuring instruments, the assembly of the ruler body and frame is a crucial step in ensuring measurement accuracy. In existing measuring instruments (such as calipers), the lower side of the ruler body and the contact surface between the ruler body and the frame are hard contact surfaces after assembly, making them prone to scratches. This can lead to uneven sliding or even jamming of the ruler body. To ensure smooth sliding, a certain gap must be allowed, and controlling this gap places high demands on the production of both the ruler body and frame. Improper gap control will affect assembly efficiency and product yield. Furthermore, after a period of use, the contact surfaces of the ruler body and frame will wear down, increasing the gap and affecting the lifespan of the calipers. Therefore, we provide a novel caliper sliding structure. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the prior art. Therefore, one objective of the present invention is to propose a novel caliper sliding structure to solve the problems mentioned in the background section.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] The novel caliper sliding structure is characterized by comprising a frame, a body, a bearing, and a shaft. The frame has a sliding groove along its length and the body is movable. The bottom of the sliding groove has a base surface that engages with the plane of the body. The two ends of the body extend through the sliding groove out of the two ends of the frame. The body moves within the sliding groove along the length of the frame. The frame has a circular groove communicating with the sliding groove and the bearing and shaft disposed within the circular groove.

[0006] The beneficial effects of this utility model are: It optimizes the basic structure of the caliper, making it more stable and reliable. When the caliper body and frame slide relative to each other after assembly, the side of the caliper body does not contact the inner side of the frame, resulting in smoother sliding and less susceptibility to jamming. This facilitates mass production, improves assembly efficiency and product qualification rate, enhances product stability, and reduces production costs.

[0007] Based on the above technical solution, the present invention can be further improved as follows:

[0008] The ruler frame is provided with at least one set of the circular groove, the bearing and the shaft at at least one end, and the bearing is perpendicular to the base surface.

[0009] The advantages of adopting the above-mentioned improvement scheme are: a circular groove is set on the lower end face of the ruler frame to accommodate the bearing, and the bearing is installed through the shaft, which makes the structure simpler and the bearing easier to install.

[0010] Furthermore, the bearing is disposed within the circular groove, the outer ring of the bearing is tangent to the ruler body, the inner ring of the bearing is fixedly connected to the shaft, and the shaft is fixedly connected to the ruler frame.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the rolling motion between the inner and outer rings of the bearing significantly reduces the frictional resistance of the contact surface, which is much smaller than the coefficient of sliding friction, thereby reducing the wear of parts.

[0012] Furthermore, the ruler body is tangentially fitted to the outer ring of the bearing and does not contact the side wall of the sliding groove. When the ruler body moves along its length, the outer ring of the bearing rolls synchronously.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the side of the ruler body does not contact the ruler frame, and the ruler body and the outer ring of the bearing are tangentially fitted with zero clearance, ensuring smooth movement of the ruler body while ensuring measurement accuracy and caliper stability.

[0020] 2. Ruler body, 3. Bearing, 4. Shaft. Detailed Implementation

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] like Figures 1 to 4As shown, a novel caliper sliding structure includes a frame 1, a body 2, a bearing 3, and a shaft 4. The frame 1 has a sliding groove 101 along its length and the body 2 is movable. The bottom of the sliding groove 101 has a base surface 102 that engages with the plane of the body 2. The two ends of the body 2 extend out of the frame 1 through the sliding groove 101. The body 2 moves within the sliding groove 101 along the length of the frame 1. The frame 1 has a circular groove 103 communicating with the sliding groove 101 and the bearing 3 and the shaft 4 disposed within the circular groove 103.

[0023] In the above embodiment, one end of the ruler frame 1 is provided with two sets of circular grooves 103, the bearing 3 and the shaft 4, and the bearing 3 is perpendicular to the base surface 102.

[0024] In the above embodiment, the bearing 3 is disposed in the circular groove 103, the outer ring of the bearing 3 is tangent to the ruler body 2, the inner ring of the bearing 3 is fixedly connected to the shaft 4, and the shaft 4 is fixedly connected to the ruler frame 1.

[0025] In the above embodiment, the ruler body 2 is tangentially fitted to the outer ring of the bearing 3 and does not contact the side wall of the sliding groove 101. When the ruler body 2 moves along its length direction, the outer ring of the bearing 3 rolls synchronously.

[0026] In this embodiment, the basic structure of the caliper is optimized, making it more stable and reliable. When the caliper body and frame slide relative to each other after assembly, the side of the caliper body does not contact the inner side of the frame. The sliding of the caliper body is smooth and not easily jammed, which is beneficial for mass production, improves assembly efficiency and product qualification rate, enhances product stability, and reduces production costs.

[0027] A circular groove is provided on the lower end face of the ruler frame to accommodate the bearing, and the bearing is installed through the shaft, which simplifies the structure and makes the bearing installation more convenient.

[0028] The rolling of the bearing reduces friction through the rolling motion of the rolling elements (such as balls, rollers, etc.). The rolling friction coefficient is much lower than that of sliding friction. Compared with the existing caliper structure, the rigid contact surface between the caliper body and the frame of this utility model is reduced, the frictional resistance of the caliper body contact surface is significantly reduced, and the wear on the caliper body surface is reduced.

[0029] The side of the ruler body does not contact the ruler frame, and the ruler body and the outer ring of the bearing are tangentially fitted with zero clearance, ensuring smooth movement of the ruler body while ensuring measurement accuracy and caliper stability.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
