Description

Technical Field

[0001] This utility model relates to the field of sensor storage technology, and more specifically, it relates to a sensor that is easy to store. Background Technology

[0002] During the installation and use of sensors, the wiring harness, as a key component for signal transmission and power supply, directly affects the ease of use and lifespan of the sensor. Currently, the industry commonly uses manual winding to wind the wiring harness onto the sensor body or an additional winding device. This process is not only time-consuming and labor-intensive, but also requires constant adjustment of the wiring harness tension and winding angle during winding, making it difficult for a single person to complete efficiently, which seriously affects installation and maintenance efficiency.

[0003] Existing manual winding methods lack dedicated protective structures, leaving the wound wire harness directly exposed to the external environment, making it susceptible to corrosion from dust and moisture. Furthermore, during handling, storage, or use, the wire harness surface is prone to friction and collision with other components, leading to insulation wear and wire breakage. This not only shortens the lifespan of the wire harness but may also cause signal transmission failures or safety hazards, failing to provide effective protection for the wound wire harness.

[0004] More importantly, manually wound wire harnesses rely solely on their own friction to maintain their winding state, lacking reliable positioning and fixing structures. When subjected to slight external pulling or vibration, they are prone to loosening and falling off. Loose wire harnesses may become tangled and knotted with surrounding components, which not only affects the normal operation of the sensor but also increases the difficulty of subsequent sorting and maintenance. In fact, pulling the wire harness may even cause the sensor interface to loosen, further affecting the stability and reliability of the equipment.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a sensor that is easy to store. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sensor that is easy to store.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sensor that is easy to store, comprising a sensor body, characterized in that a housing is provided at one end of the sensor body, the housing and the sensor together form a cavity, a winding post is provided in the cavity, one end of the winding post is provided on the sensor body, and a wire bundle is wound on the winding post. The housing is rotatably mounted on the sensor body, and a groove is formed on the surface of the housing for the wire harness to pass through. When the housing is rotated circumferentially, the groove drives the wire harness to move synchronously circumferentially. The wire harness slides in the groove and winds around the winding post to complete the winding. The housing is controlled to pull the wire harness outward to tighten it. The wire harness gives the winding post a rotational tendency, causing the winding post to drive the sensor body to rotate based on the housing. The wire harness wound on the winding post moves to the outside through the groove.

[0008] Furthermore, the groove is formed along the winding post direction and is elongated.

[0009] Furthermore, a wire assembly is provided inside the cavity, which is used to guide the wire bundle so that the wire bundle is evenly wound on the winding post.

[0010] Furthermore, the wire assembly includes a slide rod arranged along the winding post, a wire block disposed on the slide rod, and a wire hole provided on the wire block for the wire bundle to pass through. The other end of the wire bundle passes through the wire hole and extends to the outside through the sliding groove. The slide rod is connected to a limiting rod, and the limiting rod is slidably connected to the slide rod. The limiting rod is used to limit the movement trajectory of the slide rod. The slide rod is connected to a driving mechanism, which is used to drive the slide rod to reciprocate within the cavity.

[0011] Furthermore, the driving mechanism includes a guide block disposed on the slide rod, and a guide groove for sliding the guide block is provided on the inner wall of the housing. The guide groove is in the shape of a continuous ellipse and is disposed around the inner wall of the housing. The guide groove is obliquely surrounding the inner wall of the housing and corresponds to the upper and lower ends of the housing.

[0012] Furthermore, the housing is connected to a cover plate by a torsion spring, and a wire groove for storing the wire harness is formed on the surface of the housing. The wire groove communicates with a sliding groove and extends to the cover plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By utilizing the rotating mechanism between the housing and the sensor body, the wire harness can be wound up simply by rotating the housing and released by pulling it. The entire operation requires no complex adjustments and can be completed quickly by a single person, significantly improving the convenience and efficiency of wire harness winding and unwinding, especially suitable for installation and maintenance in confined spaces. Simultaneously, the housing and sensor body form a sealed cavity, housing the winding post and wire harness within the cavity. This effectively prevents the intrusion of dust and moisture, avoids friction and collision between the wire harness and external components, greatly reduces wire harness wear and the risk of failure, and extends the wire harness's service life. Meanwhile, the wire assembly, in conjunction with the drive mechanism, guides the wire harness to wind evenly around the winding post, avoiding stress concentration and loosening issues caused by overlapping and tangling. This design not only ensures the stability of the wire harness after winding but also improves the space utilization of the winding post, resulting in a neat wire harness arrangement and further guaranteeing the stability of sensor signal transmission and the overall reliability of the equipment.

[0021] This invention provides a conveniently stored sensor, comprising a sensor body 1, which is a cylindrical structure with an annular step on its outer circumference. The inner ring of a bearing 6 is interference-fitted and fixed on the annular step. The housing 2 is a hollow cylindrical structure made of engineering plastic. An annular mounting groove is provided on the inner wall of the housing 2 at a corresponding position. The outer ring of the bearing 6 is embedded in the annular mounting groove to ensure that the housing 2 rotates coaxially around the sensor body 1 smoothly. A hollow area is formed inside the housing 2, and a sealed cavity is formed between the housing 2 and the sensor body 1. One end of the sensor body 1 is connected to a winding post 5 by a fixing method. The winding post 5 is a cylindrical structure with its axis collinear with the axis of the sensor body 1. The winding post 5 is located inside the cavity, and an annular groove is provided on the outer circumference of the winding post 5. One end of a wire harness 3 is embedded in the annular groove and fixed by a fixing method to prevent the wire harness 3 from sliding relative to the winding post 5. The wire harness 3 is made of wear-resistant and tensile-resistant material. The outer circumference of the housing 2 is provided with an anti-slip structure to facilitate hand grip and operation. The surface of the housing 2 is provided with a groove 4 for the wire harness 3 to pass through. The inner wall of the groove 4 is treated to reduce friction. The wire harness 3 is wound on the winding post 5, and the other end extends from the groove 4 to the outside.

[0022] To wind up the wire harness 3, hold the sensor body 1 with one hand and the housing 2 with the anti-slip structure with the other. Rotate the housing 2 along the winding direction of the wire harness 3. Since the wire harness 3 is fixed in the annular groove of the winding post 5, the wire harness 3 will rotate synchronously with the slide 4 when the housing 2 rotates. Under the guidance of the slide 4, it will gradually wind along the surface of the winding post 5. During the winding process, the tension of the wire harness 3 is kept uniform to avoid knotting or stacking. Continue until the wire harness 3 is wound to a suitable length, then stop rotating the housing 2. At this point, the winding of the wire harness 3 is complete.

[0023] To release the wire harness 3, hold the housing 2 with one hand and pull the end of the wire harness 3 that extends to the outside with the other hand, and apply outward pulling force to tighten the wire harness 3. This pulling force can overcome the static friction between the winding post 5 and the wire harness 3 and the rotational resistance of the bearing 6. The wire harness 3 will tend to rotate on the winding post 5. Since the housing 2 is fixed, pulling the wire harness 3 will cause the winding post 5 to drive the sensor body 1 to rotate synchronously. The other end of the sensor body 1 is provided with a limiting boss to prevent axial movement during release. The wire harness 3 is thus smoothly unwound on the winding post 5 and pulled out to the outside.

[0024] In summary, the winding and unwinding of the wire harness 3 can be completed by rotating the housing 2 or pulling the wire harness 3. Not only is the operation simple, but the housing 2 can also protect the wire harness 3 inside.

[0025] Optionally, to avoid the groove 4 being too small and the wire harness 3 only being able to be wound on a portion of the winding post 5, the groove 4 can be made into a long strip with a length consistent with the axial length of the winding post 5 and set along the direction of the winding post 5. The two ends of the groove 4 are provided with arc transition parts to avoid scratching the wire harness 3. The inner wall of the groove 4 is provided with several evenly distributed guide ribs along the length direction. When winding the wire harness 3, by reciprocating the hand along the length direction of the groove 4, the wire harness 3 can be wound in a spiral shape on the winding post 5, thereby evenly winding on the winding post 5 and improving the space utilization of the winding post 5.

[0026] Optionally, when winding the wire harness 3, guiding it by hand along the slide groove 4 is cumbersome and inconvenient for single-person operation. Therefore, a wire assembly 7 is installed inside the cavity, mounted on the sensor body 1. During winding, as the housing 2 rotates, the wire assembly 7 guides the wire harness 3 to reciprocate along the winding post 5, causing it to wrap evenly around the surface of the winding post 5, enhancing the winding effect. The wire assembly 7 includes a slide rod 11, which has a regular structure and is made of wear-resistant material. Its length matches the axial length of the winding post 5. The slide rod 11 is positioned along the winding post 5, and a wire block 12 is fixedly connected to it. The wire block 12 has a wire hole 13 for the wire harness 3 to pass through. A wear-resistant bushing is embedded in the wire hole 13, and both ends of the bushing are chamfered. The other end of the wire harness 3 passes through the wire hole 13 and extends to the outside through the slide groove 4. The sensor body 1 is provided with several limiting rods 15, which are symmetrically arranged on both sides of the slide rod 11. The axis of the limiting rod 15 is parallel to the axis of the winding post 5. The two ends of the limiting rod 15 are fixed to the end face of the sensor body 1 by a fixing method. The slide rod 11 is provided with corresponding sliding holes that are adapted to the limiting rods 15. The limiting rods 15 are used to restrict the movement trajectory of the slide rod 11, so that the slide rod 11 can only move back and forth along the direction of the winding post 5. The two ends of the slide rod 11 are provided with limiting protrusions to avoid collision with other components.

[0027] A drive mechanism is also provided, which drives the slide rod 11 to reciprocate within the cavity, thereby ensuring that the wire harness 3 is evenly wound around the surface of the winding post 5 under the constraint of the wire hole 13. The drive mechanism is a linear reciprocating drive mechanism, which can be implemented by a crank-slider mechanism, a cam mechanism, or a four-bar linkage, etc. A simpler mechanism is described below: The drive mechanism includes a guide block 14 located at one end of the slide rod 11. A rolling component is fitted onto the outer circumference of the guide block 14. The end of the slide rod 11 is fixedly connected to the guide block 14, and an anti-loosening structure is provided at the connection point. A guide groove 8 is provided inside the housing 2 for the guide block 14 to slide. The guide groove 8 is a continuous ellipse, surrounding the entire inner wall of the housing 2, and is obliquely circumferentially shaped. The cross-section is designed to prevent detachment. The shape of the guide block 14 is complementary to the cross-section of the guide groove 8 to prevent detachment. The guide groove 8 is close to the upper and lower ends of the housing 2. The guide block 14 is slidably disposed in the guide groove 8. The inner wall of the guide groove 8 is lubricated. When the housing 2 rotates, the guide block 14 moves along the trajectory of the guide groove 8 under the action of the guide groove 8. Due to the limitation of the limit rod 15, the guide block 14 will reciprocate at both ends of the winding post 5 under the action of the guide groove 8. The speed of reciprocating movement is proportional to the rotation speed of the housing 2, thereby realizing the guidance of the wire harness 3 when winding the wire.

[0028] Optionally, after the wire harness 3 is wound up, to prevent the other end of the wire harness 3 from swinging, a wire groove 9 is provided on the surface of the housing 2 at the position corresponding to the sliding groove 4. The cross-section of the wire groove 9 is adapted to the shape of the wire harness 3, and the inner wall of the wire groove 9 is provided with an elastic pad. The wire harness 3 is accommodated in the wire groove 9. The housing 2 is connected to a cover plate 10 by a torsion spring. The cover plate 10 has an arc-shaped plate structure, and its curvature is adapted to the outer peripheral surface of the housing 2. The wire groove 9 extends into the cover plate 10. One end of the cover plate 10 is hinged to the housing 2 by a hinge, and a torsion spring is sleeved on the hinge shaft. One end of the torsion spring is embedded in the mounting groove of the housing 2, and the other end is embedded in the slot of the cover plate 10. The free end of the cover plate 10 is provided with a buckle protrusion, and the housing 2 is provided with a buckle groove at the corresponding position. The inner side of the cover plate 10 is provided with a soft pressure block. The other end of the wire harness 3 is embedded in the wire groove 9. The cover plate 10 is rotated in the opposite direction to allow the torsion spring to accumulate elastic force. The force is then evenly applied to the wire harness 3 through the pressure block. At the same time, the buckle protrusion and the buckle groove engage to achieve secondary fixation, thus completing the fixation of the wire harness 3. The end of the wire groove 9 is provided with a guide structure to facilitate the embedding of the wire harness 3.

[0029] Optionally, to increase the winding capacity of the winding post 5, a spiral guide groove is provided on the outer circumferential surface of the winding post 5. The pitch of the guide groove is adapted to the wire harness 3. The wire assembly 7 guides the wire harness 3 to be embedded in the spiral guide groove, further ensuring that the wire harness 3 is wound neatly and avoiding stacking. Limiting baffles are provided at both ends of the winding post 5. The diameter of the limiting baffles is larger than the diameter of the winding post 5 to prevent the wire harness 3 from falling off from both ends of the winding post 5.

[0030] Optionally, to achieve automatic positioning of the wire harness 3 after winding, a positioning mechanism is provided between the sensor body 1 and the housing 2. The positioning mechanism includes an elastic protrusion ball disposed on the inner wall of the housing 2 and a positioning groove disposed on the outer circumferential surface of the sensor body 1. The elastic protrusion ball is mounted on the housing 2 by a spring. After winding, the elastic protrusion ball is engaged in the positioning groove, restricting the relative rotation between the housing 2 and the sensor body 1 and preventing the wire harness 3 from loosening on its own. Multiple positioning grooves are evenly distributed along the circumference of the sensor body 1, and different positioning positions can be selected according to the winding length of the wire harness 3.

[0031] Optionally, to prevent dust and moisture from entering the cavity and affecting the internal components and wiring harness 3, a dustproof sealing ring is provided at the rotatable connection between the housing 2 and the sensor body 1. The sealing ring is fitted on the outer circumferential surface of the sensor body 1 and is tightly fitted to the inner wall of the housing 2. A flexible dustproof curtain is provided at the opening of the slide groove 4. One end of the dustproof curtain is fixed to the edge of the slide groove 4, and the other end is fitted to the wiring harness 3. This does not affect the movement of the wiring harness 3 and can prevent dust from entering the cavity.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model.
