Detailed Description

The utility model is further described below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, the multi-structure measuring tool of the present embodiment mainly includes a base 10, a locking assembly 20, a spring assembly 30, and a detecting block 40.

The base 10 is provided with a detection space 11 with an open mouth for placing a part of the product 50 to be detected, which needs to be detected; the base 10 is further provided with a receiving cavity 12 for assembling the locking assembly 20 and the spring assembly 30, and the receiving cavity 12 is communicated to the detection space 11. In addition, the base 10 is further provided with an installation opening 13 matched with the detection block 40, and the installation opening 13 is also communicated to the detection space 11.

Referring to fig. 3, the locking assembly 20 includes a rod portion 21 and a locking portion 22 disposed on the rod portion 21, wherein an inner wall of the accommodating cavity 12 of the base 10 is hollow around the outer side of the rod portion 21, so as to allow the locking portion 22 to extend into the detection space 11 to contact with the product 50 to be detected.

The spring assembly 30 is coupled to the locking assembly 20 and operates substantially as follows:

when a product to be tested is loaded, the locking assembly 20 is moved by an external force in a direction that the locking portion 22 is separated from the detection space 11, and the spring assembly 30 is driven by the locking assembly 20 to elastically deform. At this time, the portion of the product 50 to be tested can be placed into the testing space 11, and then the external force applied to the locking assembly 20 disappears, and the portion of the product 50 to be tested is pressed against by the restoring force of the spring assembly 30 to complete the loading.

When the product to be tested is unloaded, the locking assembly 20 is moved again by the external force in the direction of separating the locking part 22 from the detection space 11, and at this time, the locking part 22 is separated from the product, so that the product can be taken out. Preferably, after the external force acting on the locking assembly 20 disappears, that is, in a state of not being used at ordinary times, the locking portion 22 of the locking assembly 20 extends into the detection space 11 under the action of the spring assembly 30.

The detecting block 40 is installed at the installation opening 13 of the base 10, and a through hole 41 leading to the detecting space 11 is provided on the detecting block 40, so as to allow the no-go gauge 42 to pass through and extend into the detecting space 11, so as to detect the corresponding structure of the product 50 to be detected loaded in the detecting space 11.

Referring to fig. 4, the product 50 to be tested is provided with a substantially U-shaped slot 51, the slot 51 has an opening 51-a and a circular arc portion 51-b inside the opening 51-a, the width of the circular arc portion 51-b is slightly smaller than that of the opening 51-a, and a circular arc step 52 is formed at a substantially middle position of the slot 51, i.e., at a position where the opening 51-a is adjacent to the circular arc portion 51-b.

Preferably, the locking portion 22 of the locking assembly 20 matches with the opening 51-a of the U-shaped slot 51 of the product 50 to be tested.

After loading, the locking portion 22 of the locking assembly 20 can be abutted against the step 52 of the U-shaped slot 51 of the product 50 to be tested.

In the horizontal direction, the through hole 41 on the detection block 40 is positioned to align with the circular arc portion 51-b of the slot 51 of the standard product. The no-go gauge 42 can reach the arc part 51-b of the slot 51 after passing through the through hole 41 on the detection block 40. At this time, if all other parameters of the product 50 to be measured are qualified, the no-go gauge 42 may pass through or be blocked by the arc portion 51-b of the slot 51, and then it is determined whether the size of the arc portion 51-b of the slot 51 is qualified.

In addition, when the relevant parameters of the product 50 to be tested are not qualified, for example, the height H from the center of the circular arc portion 51-b of the open slot 51 to the bottom surface of the product 50 to be tested is not qualified, it can also be determined through the above-mentioned detection process.

For example, if the height H is too small, which corresponds to the center of the circular arc portion 51-b moving downward, the circular arc portion 51-b will not be aligned with the through hole 41 of the detection block 40, and the stop gauge 42 will not pass through the circular arc portion 51-b of the slot 51 after passing through the through hole 41 of the detection block 40.

Therefore, the multi-structure measuring gauge can simultaneously realize the size and the relative position of the slot 51 on the product 50 to be measured, and the detection efficiency is improved.

Further, a pressing block 14 is also arranged on the base 10. The pressing block 14 is fixed on the base 10, and may be detachably fixed and connected, or may be integrally connected, without limitation.

The pressing piece 14 is provided with a through hole 140, and is sleeved outside the rod 21 of the locking assembly 20 together with the base 10 through the through hole 140. The width of the through hole 140 on the pressing block 14 is smaller than the width of the accommodating cavity 12 of the base 10, so as to form a limiting step 141.

The spring assembly 30 is preferably a coil spring. The spring assembly 30 is fitted over the shaft portion 21 of the locking assembly 20 and has one end fixed to the locking assembly 20. The other end of the spring assembly 30 abuts against the limit step 141, or is fixed with the pressing block 14, or is fixed with the base 10.

Further, a handle 23 is disposed on the rod 21 of the locking assembly 20 for easy operation.

In a preferred embodiment, the base 10 is provided with two mounting openings 13 matching with the detecting block 40, and the two mounting openings 13 are symmetrically arranged on the front and back of the base 10, so as to be suitable for the product 50 to be tested with a substantially U-shaped cross section and provided with the symmetrical slots 51.

As shown in fig. 5, preferably, the detecting block 40 is substantially "T" shaped, one side of which is provided with a bending portion 43, and an inner corner of the bending portion 43 is provided with a strip-shaped slot 44. The bending part 43 can play a limiting role, and the bending part 43 can be set to be a structure extending into the detection space 11, so that the product 50 to be detected can be supported on the bending part 43. The strip-shaped slot 44 can also provide a space for accommodating burrs, so as to prevent the burrs on the edge of the product 50 to be tested from being squeezed between the product 50 to be tested and the base 10 or the bent portion 43 to cause the product 50 to be tested to tilt.

The embodiments of the present invention are merely illustrative, and not restrictive, of the scope of the claims, and other substantially equivalent alternatives may occur to those skilled in the art and are within the scope of the present invention.
