Description

Technical Field

[0001] This invention relates to the field of semi-digital external reading zero-position instrument technology, and in particular to a semi-digital external reading zero-position instrument based on a linear displacement sensor. Background Technology

[0002] The semi-digital external reading zero-position instrument based on a linear displacement sensor is a measuring instrument that combines linear displacement sensor technology with a semi-digital reading method. It utilizes a linear displacement sensor to accurately measure the displacement of an object and displays the reading externally via a semi-digital display, thereby achieving precise measurement and monitoring of the object's displacement.

[0003] The working principle of this instrument is mainly based on the measurement principle of a linear displacement sensor. The linear displacement sensor contains a sensing element that changes with the displacement of the object and converts this change into an electrical signal output. The instrument also contains a signal processing circuit and a display module. The signal processing circuit is responsible for receiving and processing the electrical signal from the sensor and converting it into a readable digital or analog signal. The display module is responsible for displaying the processed signal in a semi-digital format for the user to read.

[0004] However, existing semi-digital external reading zero-position instruments based on linear displacement sensors require a bracket for support and fixation during use. The assembly of the zero-position instrument with the bracket requires the use of multiple threaded components and connecting accessories, which is a cumbersome process that consumes a lot of the staff's energy and time. After assembly and fixation, the bracket does not have a component to adjust the height of the measuring instrument, thus reducing the ease of use and assembly of the measuring instrument.

[0018] The beneficial effects of this invention are:

[0019] 1. By using the two clamping components of the device, turning the handle drives the double-headed threaded rod to rotate, which in turn drives the two threaded blocks to move in opposite directions, which in turn drives the two connecting columns to move in opposite directions. This causes the two clamping components to move in opposite directions, clamping and fixing the zero-position instrument body. This completes the rapid assembly of the zero-position instrument body and the bracket, eliminating the cumbersome process of using multiple threaded components and connecting accessories for combination and fixing, and greatly reducing the workload of the staff.

[0020] 2. The crank handle on this device rotates the threaded rod, causing the threaded tube to move upwards and the connecting rod to move upwards. This, in turn, causes the support rod one to move in the same direction as the threaded rod one, and the support rod two to move in the same direction as the threaded rod one. This reduces the angle between the support rod one and the support rod two, thus adjusting the height of the support. Conversely, adjusting the height of the support lowers the height of the support. By adjusting the height of the support, the relative positional relationship between the zero-position instrument body and the target measurement point can be ensured to be accurate, thereby improving the accuracy and reliability of the measurement.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Reference Figure 1-6 The first embodiment of the present invention provides a semi-digital external reading zero-position instrument based on a linear displacement sensor, including a zero-position instrument body 1 and a mounting plate 3. The top of the mounting plate 3 has two opposing clamping members 2. The bottom of the mounting plate 3 is fixedly connected to a bearing plate 9. The bottom of the bearing plate 9 is rotatably connected to a threaded rod 6. The end of the threaded rod 6 away from the bearing plate 9 is fixedly connected to a crank handle 10. The bottom of the bearing plate 9 is hinged to a support rod 4. The outer wall of the support rod 4 is hinged to a connecting rod 8.

[0032] A hinge is hinged to the end of the connecting rod 8 away from the support rod 4. A threaded tube 7 is fixedly connected to the side of the hinge away from the connecting rod 8. The inner wall of the threaded tube 7 is rotatably connected to the outer wall of the threaded rod 6. A support rod 5 is slidably connected to the outer wall of the support rod 4. A sliding groove is provided on the top of the mounting plate 3. A connecting column 18 is slidably connected to the inner wall of the sliding groove. A threaded block 15 is fixedly connected to the bottom of the connecting column 18. The top of the connecting column 18 is fixedly connected to the bottom of the clamping member 2.

[0033] The inner wall of the mounting plate 3 is rotatably connected to a double-ended threaded rod 17. The inner wall of the threaded block 15 is rotatably connected to the outer wall of the double-ended threaded rod 17. A knob is fixedly connected to the end of the double-ended threaded rod 17 away from the mounting plate 3. A guide rod 13 is fixedly connected to the inner wall of the mounting plate 3. A guide block 14 is slidably connected to the outer wall of the guide rod 13. A connecting plate 16 is fixedly connected to the outer wall of the guide block 14. The side of the connecting plate 16 away from the guide block 14 is fixedly connected to the outer wall of the threaded block 15. An adjustment box 11 is fixedly installed on the side of the support rod 2 5 away from the threaded rod 1 6. A lifting rod 23 is slidably connected to the inner wall of the adjustment box 11.

[0034] Example 2

[0035] Reference Figure 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a limit block is fixedly connected to the outer wall of the lifting rod 23, a return spring 24 is sleeved on the outer wall of the lifting rod 23, a lifting block 22 is fixedly connected to the end of the lifting rod 23 away from the adjusting box 11, a plurality of slots are opened on the outer wall of the support rod 1 4 to facilitate the insertion of the lifting rod 23, a rubber anti-slip block is fixedly connected to the end of the support rod 2 5 away from the support rod 1 4, a sliding box 12 is fixedly installed on the side of the support rod 2 5 near the threaded rod 1 6, and a threaded rod 2 19 is rotatably connected to the inner wall of the sliding box 12;

[0036] An adjusting block is fixedly connected to the end of the threaded rod 19 away from the sliding box 12. An adjusting plate 20 is rotatably connected to the end of the threaded rod 19 away from the adjusting block. An adjusting rod 21 is fixedly connected to the end of the adjusting plate 20 away from the threaded rod 19. A roller is fixedly connected to the end of the adjusting rod 21 away from the adjusting plate 20. Rotating the adjusting block causes the threaded rod 19 to rotate, which in turn moves the adjusting plate 20, thereby moving the adjusting rod 21. This controls the extension and retraction of the roller. The roller can be moved upwards without using it, allowing the rubber anti-slip block to contact the ground and improving the stability of the bracket.

[0037] The remaining structure is the same as that in Example 1.

[0038] During use, the staff first places the zero-position instrument body 1 between the two clamping parts 2, turns the handle 10 to drive the double-headed threaded rod 17 to rotate, drives the two threaded blocks 15 to move in opposite directions, drives the two connecting columns 18 to move in opposite directions, thereby driving the two clamping parts 2 to move in opposite directions, clamping and fixing the zero-position instrument body 1. This completes the quick assembly of the zero-position instrument body 1 and the bracket, eliminating the cumbersome process of using multiple threaded components and connecting accessories for combination and fixing, and greatly reducing the workload of the staff.

[0039] During use, when the height of the bracket needs to be increased, the operator turns the crank handle 10 clockwise, causing the threaded rod 6 to rotate, which in turn moves the threaded tube 7 upward and the connecting rod 8 upward. This causes the support rod 4 to move towards the threaded rod 6, and the support rod 5 to move towards the threaded rod 6, reducing the angle between the support rods 4 and 5, thus increasing the height of the bracket. Conversely, turning the crank handle 10 counterclockwise causes the threaded rod 6 to rotate, which in turn moves the threaded tube 7 upward and the connecting rod 8 upward. This causes the support rod 4 and 5 to move outward, increasing the angle between the support rods 4 and 5, thus decreasing the height of the bracket.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
