The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Example one

As shown in fig. 2 to 5, the embodiment provides a CM inspection pallet, which includes a pallet body 1 and a measuring tape 2, wherein one side of the pallet body 1 is provided with a U-shaped groove, the sides of the two sides of the U-shaped groove are a reference side 11 and a detection side 12, and the reference side 11 and the detection side 12 are located on the same straight line; the measuring tape 2 is connected to the plate body 1 in a sliding mode along the scale trend of the measuring tape 2, the scale trend of the measuring tape 2 is perpendicular to the detection edge 12, and the starting end of the measuring tape 2 can slide to exceed the detection edge 12.

According to the CM checking card board provided by the embodiment, the measuring scale 2 is connected to the board body 1 in a sliding mode along the scale direction, so that the measuring scale and the board body are integrated and convenient to carry; the scale trend of measuring tape 2 is perpendicular to detection limit 12, and the initiating terminal of measuring tape 2 can slide and exceed detection limit 12, as shown in fig. 5, when the benchmark limit 11 of plate body 1 is laminated in the face of CM node 100 one side, can make its initiating terminal paste on the face of CM node 100 opposite side through sliding measuring tape 2, at this moment, read the scale value that aligns with detection limit 12 on measuring tape 2 promptly for the assembly deviation value of asking. Therefore, the CM inspection cardboard that this embodiment provided, not only portable, the operating method of inspection is simple, swift moreover, can effectively improve inspection and efficiency of construction.

As shown in fig. 3, the measuring tape 2 has a measuring range of 15 cm. Of course, the ruler may be a ruler with other measuring ranges, and is not limited in detail.

Specifically, in the plate body 1 and the two of measuring tape 2, seted up connecting hole 13 on one, seted up bar hole 21 on another, bar hole 21 extends along the scale trend of measuring tape 2, wears to be equipped with the fastener in connecting hole 13 and the bar hole 21 simultaneously. The connecting hole 13 is a circular hole, and the fastener and the connecting hole 13 can move along the extending direction of the strip-shaped hole 21, so that the slide connection of the measuring tape 2 and the plate body 1 is realized. In the present embodiment, the strip-shaped hole 21 is opened in the measuring tape 2, and the connecting hole 13 is opened in the plate body 1.

Optionally, the plurality of strip-shaped holes 21 are arranged at intervals, each strip-shaped hole 21 is correspondingly provided with one connecting hole 13, and a fastener is arranged in one corresponding strip-shaped hole 21 and one connecting hole 13 in a penetrating manner. This kind of setting has improved the stability that plate body 1 and measuring tape 2 are connected for measuring tape 2 can only be along rectilinear movement for plate body 1, avoids the two relative rotation, thereby has guaranteed the accuracy of inspection. In this embodiment, the bar-shaped hole 21, the connecting hole 13 and the fastening member are all provided with two, so that the stability of the connection between the plate body 1 and the measuring tape 2 is ensured on the basis of using less materials.

As shown in fig. 6, the fastener includes a bolt 31 and a nut 32 screwed to the bolt 31, and the bolt 31 is inserted into the connecting hole 13 and the strip-shaped hole 21. The bolt 31 and the nut 32 connect the plate body 1 and the measuring tape 2 together. When the position of the measuring tape 2 needs to be moved, the nut 32 is unscrewed, and the measuring tape 2 is pushed to move relative to the plate body 1; after finishing using, remove measuring tape 2 and make its initiating terminal return to overlap with plate body 1, screw up nut 32 with the position of fixed measuring tape 2, avoid making the impaired scale inaccurate that leads to of initiating terminal because the foreign object collision. Alternatively, the fastener may have another arrangement, and the fastener includes a stud and two nuts screwed to the stud, and the tightness is adjusted by screwing one of the nuts.

Specifically, the fastener further includes a washer 33, and the washer 33 is sleeved on the bolt 31 and clamped between the plate body 1 and the head of the bolt 31. The shim 33 improves the firmness of the fastening of the plate body 1 and the measuring tape 2.

In particular, the nut 32 is located on the side of the measuring tape 2 facing away from the plate body 1. When the inspection, for the convenience of removing and observing measuring tape 2, with measuring tape 2 towards the staff, consequently, set up nut 32 in one side that measuring tape 2 deviates from plate body 1, the staff of being convenient for twists nut 32 for the operation is more convenient.

Alternatively, in other embodiments, the nut 32 may be a conventional square nut, round nut, or the like. In the present embodiment, the nut 32 is preferably a wing nut, which facilitates screwing and improves inspection efficiency.

Optionally, the measuring tape 2 is made of metal, so that the measuring tape 2 still has high strength after being provided with the strip-shaped holes 21, and the durability of the test card is improved. In this embodiment, the measuring tape 2 is made of a steel material, has sufficient strength, and is low in cost.

Example two

The present embodiment provides a CM inspection card, and for simplicity, only the difference between the second embodiment and the first embodiment will be described, the difference is that a sliding groove extending along a direction perpendicular to the detection edge 12 is provided on the plate body 1, and the measuring tape 2 is slidably connected to the sliding groove. The sliding groove can be a groove formed in the plate body 1; or a sliding channel surrounded by two opposite L-shaped plates connected on the plate body 1. The length of measuring tape 2 is greater than the length of sliding channel, is convenient for promote measuring tape 2.

Specifically, an elastic member is connected between the measuring tape 2 and the plate body 1, and when the starting end of the measuring tape 2 is aligned with the detection edge 12, the elastic member is in a free state. In this embodiment, be provided with on the plate body 1 and connect protrudingly, the one end of elastic component is connected in connecting protrudingly, and the other end is connected in measuring tape 2 for the extending direction of elastic component is the same with the scale trend of measuring tape 2. When the measuring tape is not used, the elastic piece is in a free state, and the starting end of the measuring tape 2 is aligned with the detection edge 12, so that the measuring tape is convenient to carry; when using, promote measuring tape 2 and make the elastic component tensile, measure the assembly deviation value, after reading the assembly deviation value, loosen measuring tape 2, the elastic component resumes to warp and drives measuring tape 2 and resets for the operation is more convenient. The resilient member is preferably a spring.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
