[0025] The structure of the utility model is further described below with reference to the accompanying drawings and through embodiments. It should be noted that the embodiments are descriptive rather than restrictive.

[0026] Embodiment 1:

[0027] A portable thickness gauge, see Figure 1 , Figure 5 and Figure 6 The invention point is: it includes a thickness gauge body 1, a damping hinge 2 and a wrist strap 3.

[0028] The hinge plate on one side of the damping hinge contacts and is fixedly connected to the middle of the back of the thickness gauge body. Specifically, it can be connected by screw connection, bonding or welding. In the utility model, the damping hinge is made of aluminum alloy, which has the advantages of being light and wear-resistant, and further anti-dust treatment is performed to effectively reduce wear in dusty and dusty environments. The damping hinge can be adjusted in angle and can be adjusted to hover arbitrarily within the range of 0-120°, which is convenient for users to read the value.

[0029] The wristband is droopingly connected to the lower part of the hinge plate on the other side of the damping hinge, and the wristband is tightly put on the wrist of the user, so as to realize that the thickness gauge is worn on the wrist of the user, avoiding hand-holding, and facilitating carrying and operation. The wristband can adopt a single-band structure, and both ends of the wristband are fixed on the hinge plate on the other side of the damping hinge. The wristband can adopt a double-band structure, and the upper ends of the two wristbands are connected to the hinge plate on the other side of the damping hinge. The lower ends of the two wristbands are provided with matching lock structures, which can refer to the connection form of existing watch straps, such as setting pinholes 3.2 at a certain interval on the wristband on one side, connecting a ring 3.3 at the end of the wristband on the other side, and connecting a pin 3.4 matching the socket at the inner end of the ring, and inserting the pin into the socket at different positions to realize the adjustment of the wristband to wrists of different thicknesses. In order to be suitable for wrists of different thicknesses and comfortable to wear, the wristband is preferably made of rubber material.

[0030] In order to replace the wristband, the upper end of the wristband is connected to the hinge plate on the other side of the damping hinge by a quick release method. The specific structural form that can be used is:

[0031] A T-shaped socket 3.1 with a larger top and a smaller bottom is provided on the hinge plate on the other side of the damping hinge, and a T-shaped plug of matching shape is fixed on the end of the wristband. The T-shaped plug is firmly inserted into the T-shaped socket from top to bottom, and further disassembly holes are provided at both ends of the T-shaped plug. When the wristband needs to be replaced, the auxiliary pin is inserted into the disassembly hole, and the T-shaped plug is lifted up to remove the T-shaped plug from the T-shaped socket, so that the wristband can be easily disassembled.

[0032] Embodiment 2:

[0033] A portable thickness gauge, see Figure 2-6 The invention point is: it includes a thickness gauge body, a damping hinge and a wrist strap.

[0034] Two guide bars 4 are symmetrically arranged on the back of the thickness gauge body, and slots 4.3 are arranged on the inner side of the two guide bars. The width of the slots is consistent with the thickness of the hinge plate on one side of the damping hinge, and the distance between the two slots is consistent with the width of the hinge plate on one side of the damping hinge. The upper ends of the two slots are open, and the lower ends are provided with slot bottoms. The depth of the two slots is greater than the length of the hinge plate on the other side of the damping hinge. Two groups of upper elastic limit assemblies are symmetrically arranged on the two guide bars at positions corresponding to the upper ends of the slots. The upper elastic limit assemblies are composed of a limit rod 6, a limit stopper 5 and a limit compression spring 8. A stopper clearance hole 4.2 and a limit rod insertion hole 4.1 are vertically arranged on the guide bar. The stopper clearance hole is arranged on the inner side of the limit rod insertion hole (the side close to the slot) and is connected to the slot. The limit rod insertion hole is a stepped hole with a small outside and a large inside. The limit rod is inserted into the limit rod insertion hole. The inner end of the limit rod is fixedly connected to the limit stopper. The outer end of the limit rod is fixed with an end stopper 9 to limit the inward movement of the limit rod. A limit compression spring is installed in the large hole of the limit rod insertion hole on the limit rod. The outer end of the limit compression spring is pressed and contacted with the bottom of the large hole, and the inner end of the limit compression spring is pressed against the spring stopper surface 7 on the limit rod. When the limit compression spring is in a free extension state, the limit stopper extends into the limit groove on the corresponding side. A guide slope 5.1 is provided on the inner side of the limit block. The guide slopes of the limit blocks on both sides constitute a V-shaped guide opening with a large upper part and a small lower part, which can realize the insertion of the hinge plate on one side of the damping hinge.

[0035] The width of the hinge plates on both sides of the damping hinge is greater than the width of the middle hinge part. The hinge plate on one side of the damping hinge forms an insertion fit with the slots on both sides of the back of the thickness gauge body, the lower end of the hinge plate on the side is in limited contact with the bottom of the slot, and the upper end is in limited contact with the lower end surface of the limit stopper, so that the damping hinge and the thickness gauge form a detachable fixed connection. This connection method can facilitate the removal and replacement of the damping hinge when a fault occurs in the damping hinge.

[0036] When installing the damping hinge, align one side of the damping hinge with the upper ends of the two slots and insert it downward. During the insertion process, the left and right sides of this side of the damping hinge apply an outward thrust to the limit stopper, so that the limit stopper moves outward to the stopper hole on the corresponding side. When the damping hinge is inserted into place, the upper end of this side of the damping hinge moves just below the limit stopper, and the limit stopper moves inward into the slot under the action of the limit compression spring to upper limit the damping hinge.

[0037] When the damping hinge is removed, the limit column is pulled outward to move the limit blocks on both sides into the block insertion holes on the corresponding sides. At this time, the damping hinge can be pushed up to remove the damping hinge from the slot to achieve the removal of the damping hinge.

[0038] The structure of the wristband and the connection method between the wristband and the damping hinge refer to Example 1 and will not be described in detail here.

[0039] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
