Abstract
Description
Technical Field
[0001] This utility model relates to the field of sensor technology, and in particular to a wire displacement sensor with a replaceable encoder. Background Technology
[0002] A wire displacement sensor is a sensor used to measure the displacement or position of an object. It determines the position or movement of the object by measuring the change in the length of the wire or cable. This type of sensor is commonly used in engineering, automation, machinery, aerospace and other fields to monitor the position and movement of mechanical devices, control systems or robots. The ultra-thin design of wire displacement sensors is due to a variety of reasons such as adaptability, performance and appearance. Such a design can meet space constraints, lightweight requirements, reduce interference, improve assembly convenience and meet aesthetic requirements, making the sensor more suitable for various application scenarios.
[0003] Currently, in common draw-wire displacement sensors, the encoder body and sensor body housing are integrally connected. When the encoder body fails and becomes unusable, the entire sensor becomes unusable, significantly reducing the device's lifespan and increasing economic costs. Furthermore, since there are different types of encoder bodies, and each encoder corresponds to one draw-wire position sensor, users need to purchase many sensors, resulting in high costs and the need to carry multiple sensor bodies during use, which is inconvenient. Therefore, we have designed a draw-wire displacement sensor with a replaceable encoder. Utility Model Content
[0004] The purpose of this invention is to provide a wire displacement sensor with a replaceable encoder to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A pull-wire displacement sensor with a replaceable encoder includes a housing body, an encoder, and multiple mounting blocks. A wire end is located at a corner of one side surface of the housing body, and the other end of the wire end has a pull head for connecting the free end of a pull rope. The housing body includes a first housing and a second housing. The first housing is fixedly connected to the second housing by multiple fasteners. A mounting plate body is provided on the mounting surface of the encoder. A through hole for cooperating with the encoder is formed at the center of the surface of the mounting plate body. The mounting plate body is detachably connected to the top of the first housing. The mounting plate body includes a first plate, a second plate, and a positioning plate. The second plate is fixedly disposed on the top of the first plate, and the positioning plate is fixedly disposed on the bottom of the first plate. A positioning groove for the positioning plate to be embedded is formed at the center of the top of the first housing. An opening communicating with the through hole is formed on the inner bottom wall of the positioning groove. Mounting bolts are inserted into the mounting blocks. Mounting screw holes for cooperating with the mounting bolts are formed on the top of the first housing. A locking slot is formed on the bottom of the side surface of the mounting block near the first plate.
[0007] As a preferred embodiment of this utility model: the number of the mounting blocks is three, and they are evenly distributed along the outer circumferential direction of the first disc. The top of the mounting block is provided with a groove, and the inner bottom wall of the groove is provided with a mounting hole for the screw part of the mounting bolt to be inserted. The groove is for the head of the mounting bolt to be embedded.
[0008] As a further preferred embodiment of this utility model: the first disc body, the second disc body, and the positioning disc are integrally formed, and the outer diameter of the first disc body is larger than the outer diameter of the second disc body.
[0009] As a further preferred embodiment of this utility model: the first disc body, the second disc body, and the positioning disc are arranged coaxially.
[0010] As a further preferred embodiment of this utility model: the outer diameter of the second disc body is larger than the outer diameter of the positioning disc.
[0011] As a further preferred embodiment of this utility model: the height of the bayonet is equal to the thickness of the first disc body, and the inner sidewall of the bayonet matches the outer circumferential surface of the first disc body.
[0012] As a further preferred embodiment of this utility model, the mounting block has a fan-shaped structure.
[0013] The beneficial effects of this utility model are as follows: When using this device, the positioning groove and positioning plate facilitate the quick splicing and positioning of the mounting plate body and the first housing. Then, the bayonet on the mounting block is engaged at the edge of the first plate body. Next, the mounting bolt is inserted into the mounting socket and screwed into the corresponding mounting screw hole to complete the fixed installation of the mounting block. The first plate body can be fixed by the bayonet. The mounting blocks distributed at equal intervals in three circumferential directions ensure the firmness of the connection between the mounting plate body and the first housing and facilitate subsequent disassembly. Different encoders can be replaced. When the encoder fails, it can be replaced with a new one or a different type of encoder, improving the applicability and practicality of the device. Users do not need to purchase or carry many wire displacement sensors, reducing the cost of use and improving the convenience of use. Attached Figure Description

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0023] Please see Figure 1-6 In this embodiment of the utility model, a pull-wire displacement sensor with a replaceable encoder includes a housing body 1, an encoder 4, and multiple mounting blocks 7. A wire end 5 is provided at a corner of one side surface of the housing body 1, and a pull head 6 for connecting the free end of the pull rope is provided at the other end of the wire end 5. The housing body 1 includes a first housing 15 and a second housing 16. The first housing 15 is fixedly connected to the second housing 16 by multiple fasteners 2. A mounting plate body 3 is provided on the mounting surface of the encoder 4. A connecting through hole 12 that cooperates with the encoder 4 is opened through the center of the surface of the mounting plate body 3. The mounting plate body 3 is detachably connected to the top of the first housing 15.
[0024] The mounting plate body 3 includes a first plate 10, a second plate 11, and a positioning plate 13. The second plate 11 is fixedly disposed on the top of the first plate 10, and the positioning plate 13 is fixedly disposed on the bottom of the first plate 10. A positioning groove 14 for the positioning plate 13 to be embedded is provided at the center of the top of the first housing 15. An opening communicating with the connecting through hole 12 is provided on the inner bottom wall of the positioning groove 14. The mounting block 7 has a fan-shaped structure and a mounting bolt 8 is inserted into the mounting block 7. A mounting screw hole 18 that mates with the mounting bolt 8 is provided on the top of the first housing 15. A latch 9 is provided on the bottom of the side surface of the mounting block 7 near the first plate 10. The height of the latch 9 is equal to the thickness of the first plate 10, and the inner side wall of the latch 9 matches the outer circumferential surface of the first plate 10.
[0025] There are three mounting blocks 7, which are evenly distributed along the outer circumference of the first disc 10. The top of the mounting block 7 has a groove 17, and the inner bottom wall of the groove 17 has a mounting hole 19 for the screw part of the mounting bolt 8 to be inserted. The groove 17 is for the head of the mounting bolt 8 to be embedded. When the mounting bolt 8 passes through the mounting hole 19 and is screwed into the mounting screw hole 18, the head of the mounting bolt 8 is just embedded in the groove 17, avoiding protrusions on the surface of the mounting block 7, so that the overall structure of the device has a certain aesthetic appeal.
[0026] The first disc 10, the second disc 11, and the positioning disc 13 are integrally formed. The first disc 10, the second disc 11, and the positioning disc 13 are coaxially arranged. The outer diameter of the first disc 10 is larger than the outer diameter of the second disc 11, and the outer diameter of the second disc 11 is larger than the outer diameter of the positioning disc 13.
[0027] Specifically, in use, the positioning groove 14 and positioning plate 13 facilitate the quick splicing and positioning of the mounting plate body 3 and the first housing 15. Then, the bayonet 9 on the mounting block 7 is engaged at the edge of the first plate body 10. Next, the mounting bolt 8 is inserted into the mounting socket 19 and screwed into the corresponding mounting screw hole 18 to complete the fixed installation of the mounting block 7. The first plate body 10 can be fixed by the bayonet 9. The mounting blocks 7, which are evenly distributed in three circumferential directions, ensure the firmness of the connection between the mounting plate body 3 and the first housing 15 and facilitate subsequent disassembly. Different encoders 4 can be replaced. When the encoder 4 fails, it can be replaced with a new one or a different type of encoder 4, improving the applicability and practicality of the device. Users do not need to purchase or carry many wire displacement sensors, reducing the cost of use and improving ease of use.
