Description

Technical Field

[0001] The utility model relates to the field of caliper measurement, in particular to a multifunctional caliper structure for measuring the radius of an outer arc. Background Art

[0002] At present, in order to measure the radius of an arc, measuring tools such as an R gauge or a 3D machinist are commonly used. However, the R gauge can only measure within a limited range. Although the 3D machinist can accurately measure the radius of an arc and the measuring range is not limited, it is expensive, large in size, and inconvenient to carry, resulting in limited places of use. Therefore, a caliper is needed. However, most existing calipers have a simple structure, and the measurement data is displayed on the caliper through a sliding positioning seat. The caliper does not have a good fixed structure, and is prone to displacement when measuring the radius of an outer arc, affecting the accuracy of the measurement data. The caliper does not have a good shock-absorbing and buffering structure. When the user's measuring force is too large, the caliper may be damaged, which may even seriously affect the subsequent accuracy of use, thereby easily affecting the convenience of use of the entire caliper. Utility Model Content

Then, the position of the mobile frame can be fixed by the fixing assembly to avoid displacement during use, which leads to inaccurate data measurement. Then, the shock-absorbing spring is connected with a damper through the positioning assembly to play a certain buffering role during measurement, so as to avoid the user's excessive force causing the caliper to be damaged and affect subsequent measurements, thereby greatly improving the convenience of use of the entire caliper.

[0008] Preferably, the fixing assembly includes a lifting plate, a limit rod, a first connecting rod, a connecting block and a telescopic spring. A limit rod is installed at the bottom of the lifting plate. The lower end of the limit rod passes through the movable frame and can be connected with the internal snap-fit ​​connection of any limit hole, so as to fix the position of the movable frame and avoid displacement during use, which may lead to inaccurate data measurement.

[0009] Preferably, a first connecting rod is provided on the top of the lifting plate, and a connecting block is installed on the top of the first connecting rod and at the upper end of the fixing box, and telescopic springs are connected to the left and right ends of the top of the lifting plate and inside the placement groove. Pull up the connecting block to separate the limit rod from the limit socket, and then translate the moving frame to a suitable position and let go. Due to the tension of the telescopic spring itself, the limit rod can be engaged and connected with the current limit socket.

[0010] Preferably, the positioning assembly includes a second connecting rod, a second positioning seat, a groove and a shock-absorbing spring. The right end of the second connecting rod is located inside the mounting groove, and the left end of the second connecting rod is equipped with a second positioning seat. The second positioning seat is provided with a groove at one end close to the first caliper body, and the groove is engaged with the outer wall of the first caliper body, which has good stability and facilitates measurement accuracy.

[0011] Preferably, the right end of the second connecting rod is connected to a shock-absorbing spring located inside the mounting groove, and a damper is connected to the shock-absorbing spring to provide a certain buffering effect during measurement to prevent the caliper from being damaged due to excessive force exerted by the user and affecting subsequent measurements.

It can also play a certain buffering role during measurement to avoid the user's strong force. The caliper is damaged and affects the subsequent measurement, thereby improving the convenience of use of the entire caliper to a certain extent;

[0014] 2. After the second caliper body is rotated and folded backward, the limit slot can be connected with the limit plug plate, making the folding more stable, and it is convenient to shrink and place the caliper when not in use, reducing the storage space and making it easy to carry;

[0015] 3. Pull up the connection block through the fixing assembly to separate the limit rod from the limit socket, then move the mobile frame to a suitable position and let go. Due to the tension of the telescopic spring, the limit rod can be engaged with the current limit socket, so that the position of the mobile frame can be fixed to avoid displacement during use, which leads to inaccurate data measurement.

[0016] 4. Through the positioning component, the groove is engaged with the outer wall of the first caliper body, which has good stability and is convenient for measurement accuracy.
