Description

Technical Field

[0001] The utility model relates to the technical field of laser diameter measuring instruments, in particular to a mirror cover protection structure of a laser diameter measuring instrument. Background Art

[0002] Laser diameter gauges can be used for online diameter measurement and are widely used in the enameled wire (round wire, flat wire) industry, wire and cable, optical cable and optical fiber industry, aluminum-plastic composite pipe (plastic pipe) industry, copper strip, steel strip production equipment industry, hardware precision processing and tool and mold inspection industry, fine wire drawing industry, steel metallurgy industry, 3D printing consumables industry, and measurement of the width and thickness of various round and flat objects.

[0003] A mirror cover is installed at the laser emission port and the laser receiving port of the laser diameter gauge to protect the laser emission and receiving without affecting the laser emission and reception. For example, the Chinese patent with the authorization announcement number CN204902778U and the authorization announcement date of December 23, 2015 discloses "A High-precision Laser Diameter", which provides a mirror cover substrate with a slide groove extending in the horizontal direction, and the mirror cover can be detachably installed at the slide groove of the mirror cover substrate to protect the laser emission port and the laser receiving port. At the same time, when the mirror cover needs to be removed, it is necessary to press the groove on the mirror cover with your hand and then move it to one side to realize the horizontal extraction of the mirror cover from the mirror cover substrate.

[0004] However, in the above-mentioned comparative patent, the mirror cover is fixed by the friction between the mirror cover substrate after installation. If the friction between the two is large, it will cause the problem of inconvenience in removing the mirror cover. If the friction between the two is small, it will cause the mirror cover to loosen after installation. Utility Model Content

A measurement space in the shape of a "U" is formed on the diameter gauge body. Square mounting parts are symmetrically arranged on both sides of the measurement space of the diameter gauge body. The laser emission port and the laser reception port are respectively located on the two square mounting parts. The bottom of the square mounting part and the bottom of the measurement space are arranged at intervals. Plug-in slots extending along the vertical direction are arranged on both sides of the square mounting part. Strip-shaped plug-in parts are arranged on both sides of the lens cover and are vertically plugged into the plug-in slots on both sides of the square mounting part. The height of the lens cover is the same as the height of the square mounting part. A limiting member is arranged between the square mounting part and the lens cover to limit the lower surface of the lens cover and the lower surface of the square mounting part to be in the same plane. A through hole corresponding to the laser emission port or the laser reception port is arranged in the middle of the lens cover.

[0007] By adopting the above technical solutions, strip-shaped plug-in parts are arranged on both sides of the lens cover and are vertically plugged into the plug-in slots on both sides of the square mounting part to install the lens cover on the square mounting part. During the installation process, it is limited by the limiting member, so that the lower surface of the lens cover and the lower surface of the square mounting part are in the same plane. During this process, the lens cover is installed under the action of gravity and fixed by the action of gravity after installation, so that there is no need to fix the two by a large frictional force during the plug-in installation, and finally it is convenient to install the lens cover. In addition, when the lens cover needs to be disassembled, because the bottom of the square mounting part and the bottom of the measurement space are arranged at intervals, at this time, a force is applied upward from the bottom of the lens cover to push upward, so that the lens cover moves upward a certain distance and is higher than the square mounting part. Then, the upper end of the lens cover can be held and directly removed, and finally it is convenient to disassemble the lens cover.

[0008] The further setting of the present utility model is: A limiting port is arranged in the middle of the bottom of the lens cover. The limiting member is an internal hexagonal limiting bolt threadedly connected to the lower end of the square mounting part. The upper surface of the limiting port abuts against the head end of the limiting member for limiting.

[0009] By adopting the above technical solutions, the limiting member is an internal hexagonal limiting bolt threadedly connected to the lower end of the square mounting part. The upper surface of the limiting port abuts against the head end of the limiting member for limiting, so as to conveniently make the lower surface of the lens cover and the lower surface of the square mounting part be in the same plane.

[0010] The further setting of the present utility model is: A protruding part protruding in the direction away from the square mounting part is arranged in the middle of the lens cover. The upper and lower end faces of the protruding part extend to the upper and lower end faces of the lens cover. The through hole is arranged on the protruding part, and the limiting port is arranged at the bottom of the protruding part.

[0011] By adopting the above technical solution, the setting of the protrusion can increase the structural strength of the mirror cover, and the upper and lower end surfaces of the protrusion extend to the upper and lower end surfaces of the mirror cover. At this time, the protrusion and the square mounting portion of the mirror cover are separated. When the mirror cover needs to be removed, push upward from the bottom of the protrusion, so that the mirror cover can move upward a certain distance and then be higher than the square mounting portion.

[0012] The utility model is further configured as follows: the circumferential side of the head end of the limiting member is provided with anti-slip grooves distributed in a circumferential array.

[0013] By adopting the above technical solution, the anti-slip groove on the peripheral side of the head end of the limiting member has the function of facilitating the rotation of the limiting member.

[0014] The utility model is further configured as follows: an elastic member is sleeved on the screw end of the limiting member and is pressed against the square mounting portion and the head end of the limiting member; the elastic member is an elliptical metal spring for the limiting member to pass through; and in the process of continuing to tighten the limiting member after the mirror cover is installed, the two ends of the elastic member are pressed against the inner walls on both sides of the protrusion during the deformation process.

[0015] By adopting the above technical solution, on the basis of setting the protrusion, the elastic member is set, so that after the mirror cover is installed, the limit member can be tightened continuously, so that the two ends of the elastic member can be pressed against the inner walls of the protrusion on both sides during the deformation process, thereby reinforcing the installation of the mirror cover.

Detailed implementation manners

[0023] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Embodiment 1: A mirror cover protection structure for a laser diameter measuring instrument, as Figure 1 and Figure 2 shown, includes a diameter measuring instrument body 1 having a laser emission port 11 and a laser receiving port 12, and two mirror covers 2.

[0025] As Figures 1 to 3 shown, a measuring space 13 in a "U" shape is formed on the diameter measuring instrument body 1. Square mounting portions 14 are symmetrically arranged on both sides of the measuring space 13 of the diameter measuring instrument body 1. The laser emission port 11 and the laser receiving port 12 are respectively located on the two square mounting portions 14. The bottom of the square mounting portion 14 and the bottom of the measuring space 13 are arranged at intervals. Insertion slots 15 extending along the vertical direction are arranged on both sides of the square mounting portion 14.

[0026] As Figures 2 to 4 shown, strip-shaped insertion portions 21 inserted into the insertion slots 15 on both sides of the square mounting portion 14 along the vertical direction are arranged on both sides of the mirror cover 2. The height of the mirror cover 2 is the same as the height of the square mounting portion 14. A limiting member 3 for restricting the lower surface of the mirror cover 2 and the lower surface of the square mounting portion 14 to be in the same plane is arranged between the square mounting portion 14 and the mirror cover 2. A through hole 22 corresponding to the laser emission port 11 or the laser receiving port 12 is arranged in the middle of the mirror cover 2. A limiting port 23 is arranged in the middle of the bottom of the mirror cover 2. The limiting member 3 is an internal hexagonal limiting bolt threadedly connected to the lower end of the square mounting portion 14. The upper surface of the limiting port 23 abuts against the head end 31 of the limiting member 3 for limiting.

[0027] As Figures 2 to 4 shown, at the same time, a protruding portion 24 protruding in a direction away from the square mounting portion 14 is arranged in the middle of the mirror cover 2. The upper and lower end faces of the protruding portion 24 extend to the upper and lower end faces of the mirror cover 2. The through hole 22 is arranged on the protruding portion 24. The limiting port 23 is arranged at the bottom of the protruding portion 24. Anti-slip grooves 33 distributed in a circumferential array are arranged on the circumferential side of the head end 31 of the limiting member 3.

[0028] Implementation effect: Strip-shaped plug-in parts 21 are provided on both sides of the mirror cover 2, which are plugged into the plug-in grooves 15 on both sides of the square mounting part 14 along the vertical direction, so as to realize the installation of the mirror cover 2 on the square mounting part 14, and the limiter 3 is used to limit the position during the installation process, so that the lower surface of the mirror cover 2 and the lower surface of the square mounting part 14 are located on the same plane. In this process, the mirror cover 2 is installed under the action of gravity, and is fixed by the action of gravity after installation, so that the two do not need to be fixed by a large friction force during the plug-in installation, which finally facilitates the installation of the mirror cover 2; in addition, when the mirror cover 2 needs to be removed, because the bottom of the square mounting part 14 and the bottom of the measuring space 13 are arranged at a distance, at this time, force is applied upward from the bottom of the mirror cover 2 to push it upward, so that the mirror cover 2 moves upward for a certain distance and is higher than the square mounting part 14, and the upper end of the mirror cover 2 can be held and directly removed, which finally facilitates the removal of the mirror cover 2.

[0029] The stopper 3 is a hexagonal stopper bolt threadedly connected to the lower end of the square mounting portion 14. The upper surface of the stopper opening 23 contacts the head end 31 of the stopper 3 to limit the position, so that the lower surface of the mirror cover 2 and the lower surface of the square mounting portion 14 are conveniently located on the same plane. The arrangement of the protrusion 24 can increase the structural strength of the mirror cover 2, and the upper and lower end surfaces of the protrusion 24 extend to the upper and lower end surfaces of the mirror cover 2. At this time, the protrusion 24 of the mirror cover 2 is separated from the square mounting portion 14. When the mirror cover 2 needs to be removed, it is pushed upward from the bottom of the protrusion 24, so that the mirror cover 2 moves upward a certain distance and is higher than the square mounting portion 14. The anti-slip groove 33 on the peripheral side of the head end 31 of the stopper 3 has the function of facilitating the rotation of the stopper 3.

[0030] Embodiment 2: A lens cover protection structure of a laser diameter measuring instrument, such as Figure 5 and Figure 6 As shown, the difference from Example 1 is that an elastic member 4 is sleeved on the screw end 32 of the limit member 3 and is pressed against the square mounting portion 14 and the head end 31 of the limit member 3. The elastic member 4 is an elliptical metal spring for the limit member 3 to pass through. When the limit member 3 is further tightened after the mirror cover 2 is installed, the two ends of the elastic member 4 are pressed against the inner walls on both sides of the protrusion 24 during the deformation process.

[0031] Implementation effect: By setting the elastic member 4 on the basis of setting the protrusion 24, after the mirror cover 2 is installed, the limit member 3 can be tightened continuously, so that the two ends of the elastic member 4 can be pressed against the inner walls on both sides of the protrusion 24 during the deformation process, thereby reinforcing the installation of the mirror cover 2.
