[0025] Embodiment 1

[0026] like Figures 1 to 4 As shown, a ceramic measuring tool caliper described in this embodiment has a caliper body made of zirconia ceramics, and the entire caliper is made of ceramic material. Its body includes a horizontal plate 1, and a first clamping plate 2 is fixedly installed on the lower left surface of the horizontal plate 1. An outer frame 4 is slidably sleeved on the left side of the outer wall of the horizontal plate 1, and a second clamping plate 3 is fixedly installed on the lower surface of the outer frame 4. The front surface of the horizontal plate 1 is engraved with scales 5, and a protective device 10 is tightly fitted on the right side of the horizontal plate 1.

[0027] The horizontal plate 1, the first clamping plate 2, the second clamping plate 3 and the outer frame 4 are all made of zirconia ceramics in white color. Zirconia ceramics are more accurate and durable than metal measuring tools and can meet the measurement requirements of magnetic environments in corrosive environments.

[0028] The protection device 10 includes a rubber ring 103, the outer wall of the horizontal plate 1 is sleeved with the rubber ring 103, the left outer wall of the horizontal plate 1 is slidably sleeved with a ring 104, the right side of the ring 104 is tightly fitted with the rubber ring 103, the upper and lower ends of the ring 104 are fixedly equipped with a top block 107, the right side of the top block 107 is hingedly equipped with a rotating rod 106, the right side of the rotating rod 106 is fixedly equipped with a stopper 105, the right end outer wall of the horizontal plate 1 is tightly fitted with the base 102, the upper and lower ends of the right side of the base 102 are tightly fitted with the left side of the stopper 105, and the right side of the base 102 is fixedly equipped with a rubber pad 101.

[0029] Put the ring 104 on the outer wall of the horizontal board 1, and the inner wall of the ring 104 is fitted together with the horizontal board 1, put the rubber ring 103 on the right side of the ring 104, and fit the base 102 to the left side of the horizontal board 1, pull the rotating rod 106, and the rotating rod 106 rotates under the fixation of the top block 107 until the stopper 105 fits on the right side of the base 102. When using it at the construction site, put the rubber pad 101 on the ground, and the rear surface of the horizontal board 1 is leaning against the wall or other places for temporary storage, so as to protect the right end of the horizontal board 1 and prevent the ceramic horizontal board 1 from being damaged.

[0030] Specifically, a protrusion 11 is fixedly assembled on the rear surface of the outer frame 4, a connecting rod 12 is hingedly assembled on the rear surface of the protrusion 11, a suction cup 6 is fixedly sleeved on the rear outer wall of the connecting rod 12, an outer shell 8 is slidably sleeved on the outer wall of the connecting rod 12, a spring 7 is sleeved on the outer wall of the connecting rod 12, and the spring 7 is located between the outer shell 8 and the protrusion 11.

[0031] When the device of the present invention is temporarily stored, the horizontal board 1 is easy to slip when leaning against a smooth wall, and the suction cup 6 is adsorbed on a smooth surface such as a tile or a mirror. The connecting rod 12 can rotate around the protrusion 11. Under the push of the spring 7, the shell 8 is tightly attached to the front surface of the suction cup 6. The elastic coefficient of the spring 7 is between 1N / CM and 5N / CM, which prevents air leakage from the edge of the suction cup 6.

[0032] Specifically, a hanging ring 16 is fixedly mounted on the left side of the horizontal board 1. The hanging ring 16 can be put on a hook or the like and hung, so that the horizontal board 1 can be stored conveniently to avoid being damaged by bumps when not in use and affecting normal use.

[0033] Specifically, a sleeve 5 is slidably sleeved on the right side of the outer wall of the horizontal board 1. The sleeve 5 is made of soft plastic material and can move left and right on the outer wall of the horizontal board 1. When in use, hold the sleeve 5 to increase the friction between the sleeve 5 and the ceramic horizontal board 1 to prevent the horizontal board 1 from slipping from the hand.

[0034] Working principle: During the process of construction engineering inspection, it is often necessary to use a measuring tool caliper to measure the width of items on site. When measuring the width of an item, the outer frame 4 is pulled, and the outer frame 4 moves on the outer wall of the horizontal plate 1. The outer frame 4 drives the second card plate 3 to move together, and the item to be measured is placed between the first card plate 2 and the second card plate 3. The outer frame is pulled again to make the second card plate 3 fit tightly to the surface of the object, and the position of the outer frame 4 on the scale 5 on the front surface of the horizontal plate 1 is observed, so as to measure the width of the item. The protective device 10 prevents the outer frame 4 from separating from the horizontal plate 1, and the ring 1 is placed on the outer frame 4. 04 is put on the outer wall of the horizontal board 1, the inner wall of the ring 104 is fitted with the horizontal board 1, the rubber ring 103 is put on the right side of the ring 104, the base 102 is fitted on the left side of the horizontal board 1, and the rotating rod 106 is turned. The rotating rod 106 rotates under the fixation of the top block 107 until the stopper 105 fits on the right side of the base 102. When used at a construction site, the rubber pad 101 is placed on the ground, and the rear surface of the horizontal board 1 is leaned against a wall or other location for temporary storage to protect the right end of the horizontal board 1 and prevent the bottom end of the horizontal board 1 from being damaged.

[0035] The caliper body of the present invention is made of ceramic. The hardness of ceramic is higher than that of metal, and the wear resistance and corrosion resistance are better. Ceramics are non-magnetic and have a low expansion coefficient. They are more accurate and durable than similar metal measuring tools. The hardness of the caliper is improved while the toughness of the material is also improved, which meets the measurement requirements in corrosive and magnetic environments.

[0036] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
