Description

Technical Field

[0001] The utility model relates to the technical field of height measuring devices, in particular to a height vernier caliper which is convenient for marking. Background Art

[0002] Height vernier caliper is also called height gauge for short. As the name implies, its main purpose is to measure the height of the workpiece. It is also often used to measure the shape and position tolerance dimensions, and sometimes for marking.

[0003] At present, a Chinese patent with publication number CN206469791U discloses a height vernier caliper, the technical solution of which includes a base, a main scale and a vernier, the vernier is slidably connected to the main scale, a measuring claw is fixed on one side of the vernier, a mounting groove is provided on the base, the main scale is rotatably connected in the mounting groove, a strip groove for the main scale to be sunk into is provided on the top of the base, and a positioning piece for keeping the main scale in a vertical state is provided on one side of the mounting groove, a limiting piece for limiting the rotation of the main scale is provided in the mounting groove, and by rotating one end of the main scale in the mounting groove, when the height gauge is not in use, the limitation of the limiting piece can be released, and then the main scale can be rotated to be stored, at which time the main scale will no longer occupy a high height, reducing the occupied space and being more convenient for storage, so When the height vernier caliper needs to be used, the main scale is rotated until it abuts against the positioning piece and cannot be rotated further, which means that the main scale is in a vertical state. The main scale is then limited by the limiting piece. At this time, the main scale can be fixed and the measurement operation can be performed normally. However, the existing height vernier caliper is not equipped with an auxiliary sliding structure. Therefore, when marking, the staff needs to push the entire vernier caliper on the desktop to mark. Since the base is generally heavy to ensure the stability of the main scale, it is very inconvenient when marking. At the same time, long-term friction between the base and the desktop can easily cause damage to the base, making its base not flat enough, thereby affecting the accuracy of the detection, greatly reducing the convenience of marking and the service life of the height vernier caliper. Summary of the invention

[0004] The main purpose of the utility model is to solve the problem that the above-mentioned existing height vernier caliper has no movable structure. Therefore, when marking lines, it is necessary to push the entire vernier caliper on the desktop to move and mark, which is very laborious and inconvenient. At the same time, sliding directly on the desktop is prone to wear, thereby reducing work efficiency and convenience of use, and also reducing the service life of the height vernier caliper. A height vernier caliper that is convenient for marking is provided.

[0005] The specific scheme of the utility model is: a height vernier caliper that is convenient for marking, comprising a main scale, a movable measuring claw, a slide seat and a base, the main scale is vertically installed on the slide seat, the bottom of the slide seat is fixedly connected with a slider, the top of the base is provided with a slide groove, a guide rail is provided directly below the slide groove, the guide rail is fixedly connected to the base, the slider passes through the slide groove and is slidably connected to the guide rail, a slot is provided on one side of the slider, a limit assembly is provided inside the base, the limit assembly is used to limit the slider, and the base is hollow inside.

[0006] According to the above technical solution, the slider is slidably connected to the guide rail and fixedly connected to the slide seat. Therefore, the movement of the slider can drive the slide seat to move left and right, and the slide seat drives the main ruler, so as to achieve the effect of marking. There is no need to move the base as a whole by manpower for marking, which improves the convenience and smoothness of marking.

[0007] Furthermore, the limit assembly includes a fixed block, a sliding rod, a moving block, a pulling rod, a limit block and a spring. Fixed blocks are provided at the top and bottom ends of the base. The sliding rod is fixedly installed on one end of the fixed block. The moving block is movably connected to the surface of the sliding rod. The spring is sleeved on the surface of the sliding rod and is located on one side of the moving block. A limit block is provided at one end of the moving block and a pulling rod is provided at the other end. A movable hole is provided on the surface of the base, and one end of the pulling rod passes through the movable hole. The height of the limit block matches the height of the slot.

[0008] According to the above technical solution, the slider is fixed by the limiting assembly, which can effectively limit the slider and prevent it from sliding randomly when not marking.

[0009] Furthermore, a socket is provided on the surface of the pull rod, and a latch is movably installed inside the socket.

[0010] According to the above technical solution, the pin passes through the insertion hole to achieve the function of the limit pull rod, so as to prevent the pull rod from rebounding and inserting into the card slot again when it is pulled out, thereby preventing the slider from moving.

[0011] Furthermore, an anti-slip member is provided on the surface of the slide seat.

[0012] According to the above technical solution, the anti-slip part can facilitate the user to hold the sliding seat to move, thereby improving the feel of the sliding seat and preventing slipping at the same time.

[0013] Furthermore, a mounting groove is provided on the inner side of the bottom of the base, a connecting rod and a pulley are provided inside the mounting groove, the connecting rod passes through the pulley and is rotatably connected, and both ends of the connecting rod are fixedly connected to the mounting groove.

[0014] According to the above technical solution, the pulley rotates on the connecting rod, thereby assisting the sliding seat to move on the base, thereby improving the smoothness of sliding.

[0015] Compared with the prior art, the utility model has the following advantages: the height vernier caliper is equipped with a sliding structure, which can mark lines quickly and conveniently without pushing the entire height vernier caliper for marking, making it easier and more convenient for staff to mark lines, thereby improving the convenience of use and smoothness of marking of the height vernier caliper. At the same time, the pulley and guide rail assist in movement, which avoids the traditional friction marking between the base and the desktop, thereby effectively reducing the degree of wear and tear of the base, increasing the service life and ensuring the accuracy of measurement.

DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] See also Figure 1-5 The present embodiment is a height vernier caliper convenient for marking, which is composed of a main scale, a movable measuring claw, a slide 1 and a base 2. The main scale is vertically mounted on the slide 1, and a slider 3 is fixedly connected to the bottom of the slide 1. At the same time, the slider 3 passes through the slide groove 4 on the surface of the base 2 and is slidably connected to the guide rail 5 inside the base 2. Therefore, the slide 1 slides with the guide rail 5 through the slider 3, thereby achieving the effect of the slide 1 moving on the surface of the base 2. The guide rail 5 is fixedly mounted just below the slide groove 4 and located inside the base 2. The slider 3 is hollowed out with a card slot 6, and a limit assembly is provided at the horizontal parallel position of the card slot 6. The limit assembly is used to limit the slider 3. The base 2 is hollowed out to facilitate the installation of the sliding structure and the limit assembly.

[0024] Furthermore, the surface of the slide seat 1 is wrapped with an anti-slip member 16 made of anti-slip fabric.

[0025] Furthermore, four rectangular mounting grooves 17 are hollowed out on the inner side of the bottom of the base 2, and a connecting rod 18 is fixedly installed inside the mounting groove 17. At the same time, the connecting rod 18 passes through the pulley 19, and the pulley 19 is horizontally attached to the surface of the base 2 to ensure the sliding direction. The pulley 19 is rotatably connected on the connecting rod 18.

[0026] The working principle of this embodiment is as follows: during marking, the operator holds the anti-slip part 16 on the surface of the slide 1 and then pushes the slide 1. At this time, the slide 1 moves in the guide rail 5 through the slider 3, thereby achieving the effect of assisting the slide 1 to move on the base 2. At the same time, the pulley 19 rotates on the connecting rod 18 and slides on the base 2 to improve the smoothness of the movement of the slide 1. When the slide 1 is pushed back by manpower, the slide 1 drives the moving measuring claw on the main ruler to mark, which greatly improves the convenience of marking and reduces the wear of the base 2, avoiding the traditional need to rub the base 2 on the desktop for marking.

[0027] Embodiment 2

[0028] This embodiment adds the following features on the basis of the first embodiment: a fixed block 7 is respectively provided at the top and the bottom end of the base 2, and the fixed block 7 is used to install the slide rod 7. The slide rod 7 is fixedly installed at one end of the fixed block 7. The surface of the slide rod 7 is movably connected with a moving block 9. At the same time, a spring 12 is sleeved on the surface of the slide rod 7. The spring 12 is tightly against the moving block 9. A limiting block 11 is fixed at one end of the moving block 9 and a pull rod 10 is fixed at the other end. The pull rod 10 is used to pull the moving block 9 to move on the slide rod 8. One end of the pull rod 10 passes through the movable hole 13 and a section is exposed outside the base 2 for easy use by the operator.

[0029] Furthermore, a plug hole 14 is provided on the surface of the end of the pull rod 10 close to the movable hole 13 , and a latch 15 can be installed inside the plug hole 14 . The latch 15 can penetrate the plug hole 14 to play a limiting role, thereby preventing the pull rod 10 from being automatically retracted into the movable hole 13 .

[0030] Furthermore, the height of the limiting block 11 is flush with the height of the card slot 6 , so when the limiting block 11 moves laterally, it can be inserted into the card slot 6 for limiting.

[0031] The working principle of this embodiment is as follows: when in use, the pull rod 10 is pulled outward by manpower, and the pull rod 10 moves in the movable hole 13, thereby driving the shift block 9 to move on the slide rod 7. When the shift block 9 moves, it can drive the limit block 11 to move. At the same time, the shift block 9 drives the spring 12 to stretch and retract on the slide rod 7 to perform elastic force storage movement, and then slide the slide seat 1 to the middle position of the base 2. Finally, the pull rod 10 is released, and the spring 12 performs elastic movement again, thereby pushing the shift block 9 to move on the slide rod 7 toward the slot 6, thereby driving the limit block 11 to move. The positioning block 11 is inserted into the slot 6, thereby achieving the effect of limiting the sliding block 3, which can effectively fix the slide 1 and ensure the normal implementation of the measurement process. On the contrary, when operating the first embodiment for marking again, the pull rod 10 is pulled outward again to disengage the limiting block 11 from the slot 6. When the socket 14 is exposed, the pin 15 is passed through the socket 14 to fix it, so as to prevent the pull rod 10 from rebounding by itself and driving the limiting block 11 to insert into the slot 6 for limiting. When the slide 1 loses the limit of the limiting block 11, the slide 1 can slide.
