Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a bidirectional length detection measuring instrument comprises a fixed cylinder 2, the top of the fixed cylinder 2 is in threaded connection with an end cover 6, the end cover 6 is provided with a through hole 7 for inserting a second detection head 4, the lower end of the fixed cylinder 2 is provided with a rubber cap 5, the length of the rubber cap 5 is larger than that of a first detection head 1, the rubber cap 5 protects the first detection head 1 when the first detection head 1 is not used, the outer wall of the rubber cap 5 is provided with arc-shaped grooves which are mutually symmetrical and are convenient for taking the rubber cap 5, a connecting rod 9 is arranged in the fixed cylinder 2, two ends of the connecting rod 9 are respectively provided with the first detection head 1 and the second detection head 4, a spherical groove is arranged on the connecting rod 9, a rubber ball 3 is clamped in the spherical groove, the other end of the rubber ball 3 is fixedly connected with a pointer 8, the pointer 8 acts on the spherical groove of the connecting rod 9 through the rubber ball 3 to form an elastic clamping structure, this structure is fixed effectual, and the dismouting is simple, let the change operation that damages pointer 8 more convenient, the second detects 4 outer pot heads and has spring 10, and the first 1 other ends that detect the head is the toper, the second detects the head 4 other end and is the arc, the rectangle through-hole has been seted up on the solid fixed cylinder 2, and there is the graduation apparatus at rectangle through-hole edge, and alternate in the rectangle through-hole and have the pointer 8 that is used for connecting rod 9, and the rectangle through-hole central point puts in being arranged in to pointer 8, solid fixed cylinder 2 outer ends are equipped with movable sleeve 11, movable sleeve 11 inner wall is equipped with the recess, the block has the leather collar that is used for increasing and solid fixed cylinder 2 between frictional force in the recess, after pointer 8 promotes movable sleeve 11 and removes, under the effect of leather collar, movable sleeve 11 can be fixed on solid fixed cylinder 2's outer wall.

The working principle is as follows: when the bidirectional length detection measuring instrument is used, firstly, when the pattern depth of a tire is detected, the rubber cap 5 is taken down, the first detection head 1 is inserted into the pattern groove of the tire by the operation end cover 6, the first detection head 1 is forced to drive the connecting rod 9 to move, the connecting rod 9 drives the spring 10 to be compressed movably, meanwhile, the connecting rod 9 drives the pointer 8 to move movably, the pointer 8 pushes the movable sleeve 11 to move movably, the movable sleeve 11 stops at the scale position on the fixed cylinder 2 after moving to observe the moving distance of the pointer 8, so as to obtain the pattern groove depth of the tire, then, after the work to be tested is finished, the first detection head 1 is reset under the elastic reaction of the spring 10, then the same operation as before is carried out, the second detection head 4 is inserted into the gap of the wheel of the automobile to achieve the detection of the thickness of a brake pad, then, the rubber cap 5 is sleeved on the periphery of the first detection head 1, when the pointer 8 is damaged, the pointer 8 is pulled out to separate the rubber ball 3 from the spherical groove of the connecting rod 9, and the new pointer 8 is replaced by the reverse operation, which is the using process of the bidirectional length detection measuring instrument.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
