Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

referring to the figure 1, for the utility model discloses a casing size short-term test is with examining utensil, including examining detection mouth 2 that outside-in offered on the utensil body 1, detection mouth 2 is slope section 21, and slope section 21 outside-in opening size reduces gradually, and detection mouth 2 does not pierce through and examines a body 1. The width of the gauge body 1 is larger than the diameter of the sleeve 8, so that the sleeve 8 can be completely inserted into the gauge body 1 during measurement, and the measurement accuracy is improved. The sleeve 8 is inserted into the detection port 2 to measure the size, when the size of the sleeve 8 meets the requirement, the sleeve 8 is inserted into the inclined section 21 in the detection port 2 and cannot enter one side of the detection port 2 far away from the opening, the sleeve 8 is not inserted into the detection port 2 when the size is too large, and the sleeve 8 can be inserted into one side of the detection port 2 far away from the opening when the size is too small.

The implementation principle of the embodiment is as follows: when an operator uses the detection tool for measurement, the detection tool and the sleeve 8 are respectively held by two hands, the sleeve 8 is inserted into the detection port 2 of the detection tool, the sleeve 8 is rotated in the detection port 2, the operation is simple, and whether the sleeve 8 meets the standard or not can be quickly detected.

Example two:

referring to fig. 2, the difference from the first embodiment lies in that the fixture body 1 is divided into two clamping pieces 11, each of the two clamping pieces 11 includes a horizontal portion 111 and a vertical portion 112, the two clamping pieces 11 are arranged oppositely, the vertical portions 112 are abutted against each other, and the horizontal portions 111 of the two clamping pieces 11 are parallel to each other to form the detection port 2. The adjusting assembly 3 is arranged in the checking fixture body 1, the adjusting assembly 3 comprises a threaded rod 31 and a guide rod 32, threads of the threaded rod 31 are bidirectional screw rods, one end of the guide rod 32 is fixedly connected with one clamping piece 11, the other end of the guide rod is connected with the other clamping piece 11 in a sliding mode, the threaded rod 31 is respectively connected with the two clamping pieces 11 in a rotating mode, the guide rod 32 is a square rod, and the clamping pieces 11 are prevented from rotating along with the threaded rod 31 when the threaded rod 31 is rotated. The cover is equipped with adjust knob 4 on the threaded rod 31, and when rotatory adjust knob 4, threaded rod 31 rotated, and holder 11 removed along square guide bar 32, and holder 11 moves to opposite direction, detects the corresponding increase of mouth 2, can measure the sleeve pipe 8 of different specifications.

Referring to fig. 3 and 4, the adjusting knob 4 is provided with scale marks 41, and the gauge body 1 is fixedly provided with the pointer 42, so that an operator can conveniently rotate the adjusting knob 4 to know the size of the current detection port 2 more intuitively when measuring the sleeves 8 with different specifications. The inspection device comprises an inspection device body 1 and is characterized in that a transparent protective cover 5 covering an adjusting knob 4 is arranged on the inspection device body 1, one end of the protective cover 5 is hinged to the inspection device body 1, a torsion spring 6 is arranged at the hinged position, the other end of the protective cover is buckled with a buckle on the inspection device body 1, and the protective cover 5 is always buckled with the buckle on the inspection device body 1 under the action of the torsion spring 6 in a natural state. During adjustment, the protective cover 5 and the gauge body 1 are opened after being separated, and the protective cover 5 is covered during detection.

The standard line 7 is arranged on the checking fixture, and the standard line 7 is positioned on the side wall of the inclined section 21, so that an operator can more quickly confirm whether the size of the detected sleeve is qualified.

The implementation principle of the embodiment is as follows: when measuring the casing pipes 8 with different specifications and sizes, an operator only needs to screw the adjusting knob 4 to measure the casing pipes 8 with various specifications by using one checking fixture. When the casing pipes 8 of different specifications are measured, the protective cover 5 is opened, the adjusting knob 4 is screwed to a required numerical value, an operator observes the numerical value of the pointer 42 on the checking fixture body 1 aligned to the adjusting knob 4, and after the adjusting knob 4 is adjusted, the protective cover 5 is buckled on the adjusting knob 4, so that the casing pipes 8 of different specifications can be measured. When the sleeve 8 is inserted into the detection port 2 and the sleeve 8 is located at the standard line 7 on the gauge body 1, the size of the sleeve 8 is in accordance with the specification.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
