Description

Technical Field

[0001] This utility model relates to the field of angular displacement sensors, and in particular to an encoder protection structure. Background Technology

[0002] An encoder is a device that encodes and converts signals (such as bitstreams) or data into a signal form that can be used for communication, transmission, and storage. Encoders convert angular or linear displacement into electrical signals; the former is called a code disk, and the latter a code scale. According to the readout method, encoders can be divided into contact and non-contact types; according to their working principle, encoders can be divided into incremental and absolute types. Incremental encoders convert displacement into periodic electrical signals, and then convert these electrical signals into counting pulses, using the number of pulses to represent the magnitude of the displacement. Each position of an absolute encoder corresponds to a specific digital code; therefore, its reading depends only on the starting and ending positions of the measurement, and is independent of the intermediate steps of the measurement.

[0003] Existing encoder protective structures typically include a housing, a bottom cover, and mounting components. Their construction often employs rigid connections, such as using screws or clips to secure the bottom cover to the housing, thus encapsulating the encoder body. Some structures also incorporate sealing rings or oil seals at the junction of the housing and the shaft to enhance sealing. Their working principle involves physically securing and sealing the encoder body within a closed space, preventing the intrusion of external dust and moisture, while simultaneously withstanding certain mechanical stresses to maintain structural stability. For example, some protective structures use a knob-driven lead screw to insert a fixing block into a mounting slot in the encoder end cover, thus connecting the encoder to the protective housing.

[0004] However, existing protective structures require the individual disassembly and tightening of multiple screws during installation, a cumbersome and time-consuming process that fails to meet the demands for rapid assembly. Furthermore, traditional fixing methods rely on rigid connections, which are prone to loosening when the equipment experiences vibration or impact, leading to encoder displacement or even detachment and affecting equipment stability. Additionally, some sealing structures may fail after prolonged use due to wear or aging of the seals, compromising continuous protective performance. These issues result in significant shortcomings in the installation efficiency and reliability of existing encoder protective structures, necessitating urgent improvement. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an encoder protection structure, which aims to improve the problem of cumbersome installation of protection structures in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an encoder protection structure, comprising an encoder body, two outer shells fitted on the outer side of the encoder body, a round block fixedly connected between the top ends of the two outer shells, multiple heat dissipation holes and a sliding groove inside the outer shells, sliders fixedly connected to both sides of the encoder body, a fixing block fixedly connected to the bottom end of the sliders, a telescopic rod slidably connected to the middle of the fixing block, a spring fitted on the outer side of the telescopic rod, a round rod fixedly connected to the bottom end of the telescopic rod, and a bottom cover fixedly connected between the bottom ends of the two round rods;

[0007] As a further description of the above technical solution:

[0008] A rotating column is fixedly connected to the left side of the bottom cover, and a fixed round block is rotatably connected to the outside of the rotating column. A second spring is provided inside the bottom cover, and a sliding pin is fixedly connected to the front end of the second spring. Two retaining balls are fixedly connected inside the bottom cover.

[0009] As a further description of the above technical solution:

[0010] An output rod is fixedly connected to the top of the encoder body, and the output rod is slidably connected inside the circular block;

[0011] As a further description of the above technical solution:

[0012] The bottom cover is located between the two outer shells;

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the bottom of the fixing block, and the other end of the spring is fixedly connected to the top of the round rod.

[0015] As a further description of the above technical solution:

[0016] The fixed circular block is fixedly connected to the bottom of the outer casing on the side away from the bottom cover;

[0017] As a further description of the above technical solution:

[0018] The sliding pin is slidably connected to the inner wall of the slide groove;

[0019] As a further description of the above technical solution:

[0020] The slider is slidably connected between the two outer shells.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the pressing sliding pin structure drives the retaining ball to compress and shrink, and the rotating column rotates to open the bottom cover, thereby realizing the convenient installation of the encoder body through the gap between the two outer shells and the output rod sliding into the inner wall of the circular block. After the sliding pin is released, the retaining ball resets and locks the sliding pin, and the rotating column fixes the position of the bottom cover, thereby achieving a stable clamping of the encoder body, effectively improving the installation efficiency and fixing reliability of the protective structure, and providing dustproof and anti-loosening protection for the encoder.

[0023] 2. In this utility model, the sliding structure of the slider between the two outer shells drives the fixed block to compress the spring, thereby achieving unidirectional pressure buffering and effectively reducing the risk of pressure damage to the encoder body. At the same time, the wrapping structure of the two outer shells around the encoder body and the ventilation design of the heat dissipation holes work together to achieve the effect of double protection and efficient heat dissipation. This not only prevents direct damage to the equipment from external impacts, but also prevents the encoder from overheating through the air circulation of the heat dissipation holes, thereby improving the stability and safety of the equipment operation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-2This utility model provides an embodiment comprising an encoder body 1, with two outer shells 4 fitted around the encoder body 1 to form a basic protective structure. A circular block 3 is fixedly connected between the top ends of the two outer shells 4, providing a sliding support structure for the output rod 2. Multiple heat dissipation holes 5 are provided inside the outer shells 4 to allow air circulation and prevent overheating during operation. A sliding groove 6 is provided inside the outer shells 4 to provide a guide track for the sliding of a slider 7. Slider 7 is fixedly connected to both sides of the encoder body 1, engaging with the sliding grooves 6 inside the outer shells 4 to allow the encoder body 1 to slide between the outer shells 4. A fixing block 8 is fixedly connected to the bottom of the slider 7 for mounting a telescopic rod 9 and a spring 10 to transmit motion and force. A telescopic rod 9 is slidably connected to the middle of the fixed block 8. The telescopic rod 9 is slidably connected to the middle of the fixed block 8 and can extend and retract with the movement of the fixed block 8. It works with the spring 10 to achieve a buffering function. The spring 10 is sleeved on the outside of the telescopic rod 9. The spring is compressed when subjected to pressure, which absorbs and buffers the pressure and reduces the risk of equipment damage. A round rod 11 is fixedly connected to the bottom end of the telescopic rod 9. The round rod 11 is fixedly connected to the bottom end of the telescopic rod 9 and is used to connect to the bottom cover 12 to transmit the movement and force of the telescopic rod 9. The bottom cover 12 is fixedly connected between the bottom ends of the two round rods 11. The bottom cover 12 is fixedly connected between the two outer shells 4 and is used to cooperate with the sliding pin 1. The encoder body 1 is fixed and disassembled by components 5. An output rod 2 is fixedly connected to the top of the encoder body 1. The output rod 2 is used to output the motion of the encoder body 1 to external devices. The output rod 2 is slidably connected inside the circular block 3. The output rod 2 is slidably connected inside the circular block 3 so that the motion of the encoder body 1 can be accurately transmitted through the output rod 2. At the same time, the circular block 3 plays a limiting and supporting role for the output rod 2. One end of the spring-10 is fixedly connected to the bottom of the fixing block 8. One end of the spring-10 is fixed to the bottom of the fixing block 8, and the other end is connected to the top of the circular rod 11. When the encoder body 1 is subjected to force, the fixing block 8 compresses the spring-10 to achieve buffering. The other end of the spring 10 is fixedly connected to the top of the round rod 11. This connection makes the spring 10 form an elastic connection between the fixed block 8 and the round rod 11, which, together with the telescopic rod 9, realizes the absorption and release of pressure. The slider 7 is slidably connected between the two housings 4. The slider 7 slides between the two housings 4, so that the encoder body 1 can move with the slider 7 inside the housing 4. At the same time, the housing 4 limits the slider 7 and ensures the direction of movement.

[0031] Reference Figures 1-3 A rotating column 16 is fixedly connected to the left side of the bottom cover 12. The rotating column 16 is fixedly connected to the left side of the bottom cover 12 and is used to rotatably connect with the fixed circular block 13, so that the bottom cover 12 can rotate around the rotating column 16 to realize the opening and closing action. A fixed circular block 13 is rotatably connected to the outside of the rotating column 16. The fixed circular block 13 is rotatably connected to the outside of the rotating column 16 and is fixedly connected to the bottom of the outer shell 4, providing rotational support for the bottom cover 12, so that the bottom cover 12 can rotate around the fixed circular block 13. The bottom cover 12 is provided with an interior... Spring 14, located inside the bottom cover 12, provides a restoring force to the sliding pin 15, keeping it extended when not pressed, thus achieving a fixing function. The front end of spring 14 is fixedly connected to the sliding pin 15, which slides inside the bottom cover 12 under the action of spring 14. The sliding pin 15 retracts and extends by squeezing the retaining ball 17, controlling the fixing and opening of the bottom cover 12. Two retaining balls 17 are fixedly connected inside the bottom cover 12. The bottom cover 12 is fixedly connected inside the bottom cover 12 and cooperates with the sliding pin 15. When the sliding pin 15 presses the retaining ball 17, the sliding pin 15 retracts. After being released, it returns to its original position under the action of the spring 14, thus fixing the bottom cover 12 to the outer shell 4. The bottom cover 12 is located between the two outer shells 4. The bottom cover 12 is located between the two outer shells 4 and is connected to the outer shell 4 through the rotating column 16 and the fixed round block 13, which serves to close the bottom of the outer shell 4 and fix the encoder body 1. The side of the fixed round block 13 away from the bottom cover 12 is fixedly connected to the outer shell 4. At the bottom of the outer casing 4, a fixed round block 13 is fixedly connected to the bottom of the outer casing 4 and is rotatably connected to the bottom cover 12 through a rotating column 16, so that the bottom cover 12 can rotate relative to the outer casing 4, which facilitates the installation and disassembly of the encoder body 1. The sliding pin 15 is slidably connected to the inner wall of the slide groove 6. When the sliding pin 15 is pressed, it slides in the slide groove 6 and squeezes the retaining ball 17 to achieve retraction. After being released, it is reset under the action of the second spring 14, and cooperates with the retaining ball 17 to complete the fixing and unlocking of the bottom cover 12.

[0032] Working principle: Pressing the sliding pin 15 causes it to squeeze the retaining ball 17. Due to the action of the retaining ball 17, the sliding pin 15 retracts. At this time, forcefully pulling open the bottom cover 12 causes the rotating column 16 to rotate, allowing the encoder body 1 to be inserted between the two outer shells 4. The output rod 2 slides into the inner wall of the circular block 3, thus fixing the encoder body 1. Releasing the sliding pin 15 completes the fixing. When the encoder body 1 is under pressure, the slider 7 slides between the two outer shells 4, enabling it to withstand unidirectional pressure. The encoder body 1 drives the slider 7 and the fixing block 8 to move and compress the spring 10, effectively reducing pressure and the risk of equipment damage. At the same time, the outer shells 4 on both sides also enclose the encoder body 1, achieving a double protection effect. The heat dissipation holes 5 on the outer shells 4 can effectively ventilate and dissipate heat, preventing the equipment from overheating.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
