Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a portable electronic digital caliper. Background Art

[0002] An electronic digital caliper is a modern measuring tool that combines the advantages of electronic technology and mechanical tools. It is mainly used for accurately measuring the dimensions of objects such as length, width, depth, and inner diameter, and is widely used in industrial manufacturing, machining, scientific research, and precision measurement requirements in daily life. The electronic digital caliper is widely welcomed due to its high precision, ease of use, and versatility, and is an indispensable part of modern measuring tools.

[0003] In traditional electronic digital calipers, the main body frame is usually made of stainless steel or aluminum alloy, providing the overall structural support and stability of the caliper. This part includes the main sliding tracks and fixed points of the caliper. The sliding rule is the movable part of the caliper for actual measurement. It moves along the sliding tracks on the main body frame, and precise dimension measurement is carried out through the measuring head and sensor. The sliding rule is usually also made of stainless steel. The digital display screen is used to display the measurement results, usually using liquid crystal display (LCD) technology. The control buttons are used to set the functions of the caliper, such as zero reset, unit switching, and data saving. These buttons are usually located near the digital display screen or on the side of the caliper for easy operation by the user during the measurement process.

[0004] However, in traditional electronic digital calipers, the main body frame often does not have a carrying structure. The carrying method of this kind of caliper is often to directly hold it by hand or insert it directly into the pocket through its length structure. This carrying method is not stable and may cause the caliper to be lost during movement, reducing the practicality of this digital caliper. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a portable electronic digital caliper, aiming to improve the problem that the carrying method in traditional electronic digital calipers is not stable, may cause the caliper to be lost during movement, and reduce the practicality of this digital caliper.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A portable electronic digital caliper, including a caliper main body, a fixed table is fixedly connected to the side wall of the caliper main body, a plurality of sliding grooves are opened inside the fixed table, a rotating plate is rotatably connected to the side wall of the fixed table, sliding tables are rotatably connected to both sides of the rotating plate, a plurality of pulleys are rotatably connected to the bottom of the sliding tables, the pulleys are slidably connected inside the sliding grooves, a clamping plate is fixedly connected to the top of the sliding tables, a connecting shaft is slidably connected between the plurality of sliding tables, a spring is sleeved on the outer wall of the connecting shaft, and a fixing component is arranged on the side wall of the caliper main body, and the fixing component is used to fix the shielding structure.

[0007] Furthermore, the fixing assembly includes a connecting platform, and the connecting platform is fixedly connected to the side wall of the caliper body.

[0008] Furthermore, a rotating shaft is rotatably connected inside the connecting platform, and a clamping plate is fixedly connected to an outer wall of the rotating shaft.

[0009] Furthermore, a collision plate is fixedly connected to the outer wall of the rotating shaft, and a plurality of slide rails are fixedly connected to the interior of the rotating shaft.

[0010] Furthermore, the outer wall of the slide rail is slidably connected to a slide frame, and the interior of the slide frame is rotatably connected to a plurality of rollers.

[0011] Furthermore, the roller is slidably connected inside the slide rail. The plurality of rollers are parallel to each other.

[0012] Furthermore, a clamping block is fixedly connected to the side wall of the slide, and the clamping block is inclined relative to the slide.

[0013] Furthermore, a bottom plate is fixedly connected to the bottom of the slide, and the bottom plate is slidably connected to the surface of the caliper body.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the slide is first driven to slide on the top of the fixed platform by toggling, and then the slide drives the rotating plate to rotate to make the slide on the other side move synchronously. Through the setting of the connecting shaft and the spring, the caliper can be freely fixed on the surface of the clothing through simple operation, without the need to hold it and it is relatively stable, which improves the convenience of the caliper.

[0016] 2. In the utility model, the collision plate is touched by the sliding carriage to drive the rotating shaft to rotate, so that the card plate and the card block can be engaged. At this time, the bottom plate blocks the digital display screen to protect it, preventing damage to the digital display screen during construction and measurement operations, thereby ensuring the continuous use of the caliper.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: a portable digital electronic caliper, including a caliper main body 1, a fixed platform 2 fixedly connected to the side wall of the caliper main body 1, a plurality of slide grooves 3 opened inside the fixed platform 2, a rotating plate 4 rotatably connected to the side wall of the fixed platform 2, slide tables 5 rotatably connected to both sides of the rotating plate 4, a plurality of pulleys 8 rotatably connected to the bottom of the slide tables 5, the pulleys 8 slidingly connected inside the slide grooves 3, a clamping plate 9 fixedly connected to the top of the slide tables 5, a connecting shaft 6 slidably connected between the plurality of slide tables 5, a spring 7 sleeved on the outer wall of the connecting shaft 6, and a fixing component arranged on the side wall of the caliper main body 1, and the fixing component is used for fixing the shielding structure.

[0025] Specifically, first, the clamping plate 9 is toggled, this action will cause the clamping plate 9 to be in a stressed state, and then drive the bottom slide table 5 to start to displace. The pulley 8 at the bottom of the slide table 5 will slide in the slide groove 3, and the rotating plate 4 on one side of the slide table 5 will rotate and change the inclination angle. This design enables the rotation of the rotating plate 4 to pull the slide table 5 on the other side, thereby realizing the synchronous displacement of the two slide tables 5. Through the displacement of the plurality of slide tables 5, the clamping plate 9 at the top can be kept open. When the hand is released, the spring 7, through the sleeve on the outer wall of the connecting shaft 6 and the pulling force on the two slide tables 5, quickly closes the slide tables 5, and the clamping plate 9 at the top of the slide tables 5 can achieve clamping. Through the relative clamping of the clamping plate 9, this caliper can be simply fixed on the surface of the clothing without continuous hand holding, while ensuring stability, greatly improving the convenience and practicality of this caliper.

[0026] Referring to Figure 3, The fixing component includes a connecting platform 10 which is fixedly connected to the side wall of the caliper body 1. A rotating shaft 11 is rotatably connected inside the connecting platform 10. A clamping plate 12 is fixedly connected to the outer wall of the rotating shaft 11, and a collision plate 13 is fixedly connected to the outer wall of the rotating shaft 11. A plurality of sliding rails 14 are fixedly connected inside the rotating shaft 11. A sliding frame 15 is slidably connected to the outer wall of the sliding rail 14. A plurality of rollers 16 are rotatably connected inside the sliding frame 15, and the rollers 16 are slidably connected inside the sliding rail 14. The plurality of rollers 16 are parallel to each other. A clamping block 18 is fixedly connected to the side wall of the sliding frame 15, and the clamping block 18 is inclined relative to the sliding frame 15. A bottom plate 17 is fixedly connected to the bottom of the sliding frame 15, and the bottom plate 17 is slidably connected to the surface of the caliper body 1.

[0027] Specifically, when the sliding frame 15 is pulled, this action causes the rollers 16 to slide inside the sliding rail 14, resulting in the displacement of the sliding frame 15 relative to the connecting platform 10. As the sliding frame 15 moves, it eventually touches the collision plate 13. After the collision plate 13 is stressed, it will drive the rotating shaft 11 to rotate inside the connecting platform 10. This rotation process causes a change in the angle of the clamping plate 12 on the outer wall of the rotating shaft 11, so that the clamping plate 12 can be engaged with the clamping block 18 on the side wall of the sliding frame 15. This design ensures that the bottom plate 17 at the bottom of the sliding frame 15 can effectively block the digital display screen, providing the necessary protection. Through this design, the digital display screen is effectively protected during the construction measurement operation, preventing unnecessary damage. This design significantly improves the durability and continuous usability of this caliper, ensuring its reliability and safety in various working environments.

[0028] Working principle: When this caliper needs to be used and carried, first move the clamping plate 9. When the clamping plate 9 is stressed, it drives the sliding table 5 at its bottom to displace. At this time, the pulley 8 at the bottom of the sliding table 5 slides inside the chute 3. While the sliding table 5 is displacing, it drives the rotating plate 4 on one side to rotate and change the inclination angle. The rotation of the rotating plate 4 can pull the sliding table 5 on the other side to displace synchronously. Through the displacement of multiple sliding tables 5, the clamping plate 9 at its top can be kept open. At this time, when the hand is released, the spring 7 sleeved on the outer wall of the connecting shaft 6 and the pulling force on the two sliding tables 5 can make the sliding tables 5 quickly approach each other, and the clamping plate 9 at the top of the sliding tables 5 can achieve clamping. Through the relative clamping of the clamping plate 9, this caliper can be freely fixed on the clothing surface through simple operation, without the need to hold it by hand and is relatively stable, improving the convenience of this caliper. When it is necessary to protect the digital display screen, pull the sliding frame 15. Through the sliding of the roller 16 inside the slide rail 14, the sliding frame 15 displaces relative to the connecting table 10. At this time, the sliding frame 15 touches the impact plate 13. When the impact plate 13 is stressed, it drives the rotating shaft 11 to rotate inside the connecting table 10. Through the rotation of the rotating shaft 11, the angle of the clamping plate 12 on its outer wall is changed, and the clamping plate 12 can be engaged with the clamping block 18 on the side wall of the sliding frame 15. At this time, the bottom plate 17 at the bottom of the sliding frame 15 can effectively block the digital display screen and play a protective role for it, preventing damage to the digital display screen during the construction measurement operation and ensuring the continuous usability of this caliper.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
