Description

Technical Field

[0001] This utility model relates to the field of electrical protection technology, specifically to an electrical protection device. Background Technology

[0002] In power facilities and industrial equipment, electrical boxes, as critical safety protection components, often require physical isolation via guardrails to prevent accidental contact by personnel or collisions with external objects that could cause safety hazards. However, in existing technologies, most guardrails used for electrical boxes are fixed together using bolts and nuts. This makes disassembling the guardrails inconvenient during later maintenance and inspection. Furthermore, when the electrical box needs to provide area-specific isolation, connecting each guardrail is difficult; the guardrail must be moved to the appropriate angle to ensure the bolts can pass through the corresponding bolt holes before the nuts can be used for connection. This process is time-consuming and cumbersome to use. Utility Model Content

[0003] The purpose of this utility model is to provide an electrical protection device in order to solve the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] An electrical protection device, comprising:

[0006] The guardrail is equipped with connectors that are rotatably installed at both ends in the horizontal direction, and the two connectors can be detachably connected to each other.

[0007] Two limiting plates are slidably installed on the guardrail. A limiting clip is installed on the connector. When the limiting plate is slidably inserted into the limiting clip, the rotation angle of the connector is limited.

[0008] The adjustment assembly includes a rotating component rotatably mounted on the guardrail. The rotating component is coupled to two limiting plates. The rotating component rotates in both directions to drive the limiting plates to reciprocate horizontally. When the rotating component rotates in the forward direction to move the two limiting plates away from each other, the limiting plates are inserted into the limiting clips. When the rotating component rotates in the reverse direction to move the two limiting plates closer to each other, the limiting plates disengage from the corresponding limiting clips.

[0009] Furthermore, both ends of the guardrail are vertically mounted with connecting rods in the horizontal direction. The connecting component includes two rotating rings rotatably mounted on the connecting rods. The two rotating rings are distributed vertically and vertically and connected by a frame plate. A pivot rod is vertically and rotatably mounted inside the frame plate. The pivot rod has a sliding groove and a plug-in groove. A movable plate is movably mounted in the sliding groove. The movable plate has a linear array of plug-in plates with the free end facing downward. One side of the plug-in groove has multiple vertical positioning grooves for inserting the plug-in plates. The limiting clip is mounted on the rotating ring located above.

[0010] Furthermore, the limiting device includes a large gear, which is mounted on the rotating ring, and one end of the limiting plate has an arc-shaped tooth groove for inserting into the tooth surface of the large gear.

[0011] Furthermore, the rotating component includes an adjusting rod that is vertically and rotatably mounted on the guardrail. Two movable plates are symmetrically slidably mounted on the guardrail. Two connecting rods are symmetrically hinged to the adjusting rod. The free ends of the two connecting rods are respectively hinged to the two movable plates. The two movable plates are respectively connected to two limiting plates.

[0012] Furthermore, a retaining spring is installed between the limiting plate and the guardrail. Under normal conditions, the retaining spring ensures that the limiting plate is tightly pressed against the tooth surface of the large gear.

[0013] Furthermore, a metal plate is installed at one end of the movable plate near the corresponding limiting plate. An installation groove is opened at one end of the limiting plate, and a magnet is installed in the installation groove. The limiting plate is magnetically connected to the movable plate through the magnet and the metal plate. When the two movable plates move away from each other to the maximum distance, the two limiting plates overcome the magnetic force of the retaining spring and are respectively attracted to the two metal plates, so that the two limiting plates are respectively disengaged from the corresponding large gear. A moving groove is opened on the guardrail, and a baffle is installed on the limiting plate in the moving groove.

[0014] Furthermore, the bottom of the pivot rod is concentrically constructed with a shaft passing through the frame plate, a sleeve is installed on the frame plate, a positioning pin is horizontally slidably installed at one end of the sleeve, one end of the positioning pin is an outer arc surface, two positioning recesses are opened on the shaft for the positioning pin to be inserted, and a spring is installed between the sleeve and the positioning pin.

[0015] Furthermore, a small gear that meshes with the large gear is rotatably mounted on the guardrail, and the arc-shaped tooth groove is inserted into the tooth surface of the small gear.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model allows for quick docking of adjacent guardrails by simply rotating the connecting piece to bring the two connecting pieces together. Furthermore, after multiple guardrails are assembled, simply rotating the rotating piece allows two limiting plates to be simultaneously inserted into the corresponding limiting clips, making it even more convenient to use.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figure 1-10 As shown, an embodiment of the present invention provides an electrical protection device, comprising:

[0031] Guardrail 1, with connectors 2 rotatably installed at both ends of the horizontal direction. The two connectors 2 can be detachably connected to each other. That is to say, when it is necessary to connect two guardrails 1, the rotatable design of the connectors 2 makes it easy to connect the connectors 2 between the two guardrails 1. Generally speaking, when it is necessary to enclose the electrical box, multiple guardrails 1 are enclosed in a rectangular shape. Then, the guardrails 1 that are close to each other only need to rotate the connectors 2 to make the two connectors 2 face each other, and then connect the two connectors 2 to each other through the connectors 2, thereby completing the quick docking.

[0032] Two limiting plates 3 are slidably installed on the guardrail 1. A limiting clip 4 is installed on the connector 2. When the limiting plate 3 is slidably inserted into the limiting clip 4, it limits the rotation angle of the connector 2. That is, after the connector 2 between the two guardrails 1 is connected, in order to prevent the connector 2 from rotating due to external impact, the limiting plate 3 can be moved so that the limiting plate 3 is inserted into the limiting clip 4, thereby limiting the limiting clip 4. Since the limiting clip 4 is installed on the connector 2, it indirectly limits the rotation angle of the connector 2, effectively improving the stability after connection.

[0033] The adjustment assembly includes a rotating component 5 rotatably mounted on the guardrail 1. The rotating component 5 is coupled to two limiting plates 3. The rotating component 5 rotates in both directions to drive the limiting plates 3 to reciprocate horizontally. When the rotating component 5 rotates in the forward direction to move the two limiting plates 3 away from each other, the limiting plates 3 are inserted into the limiting clips 4. When the rotating component 5 rotates in the reverse direction to move the two limiting plates 3 closer to each other, the limiting plates 3 disengage from the corresponding limiting clips 4. In other words, by rotating the rotating component 5, the movement of the two limiting plates 3 can be effectively controlled, thereby simultaneously controlling the movement of the two limiting plates 3 on the guardrail 1. After multiple guardrails 1 are enclosed, only rotating the rotating component 5 is needed to simultaneously insert the two limiting plates 3 into the corresponding limiting clips 4, making it more convenient to use.

[0034] like Figure 1 , Figure 2 and Figure 10 As shown, in some embodiments, both ends of the guardrail 1 are vertically mounted with connecting rods 201 in the horizontal direction. The connecting member 2 includes two rotating rings 202 rotatably fitted on the connecting rods 201. The two rotating rings 202 are distributed vertically and connected by a frame plate 203. A pivot rod 204 is vertically and rotatably mounted inside the frame plate 203. The pivot rod 204 has a sliding groove 205 and a plug-in groove 206. A movable plate 208 is movably mounted in the sliding groove 205. The movable plate 208 has a linear array of plug-in plates 207 with the free end facing downward. One side of the plug-in groove 206 has a plurality of vertically positioned grooves 209 for the plug-in plates. 207 Insertion: The limiting clip 4 is installed on the upper rotating ring 202. That is, after the frame plate 203 is rotated, the two pivot rods 204 between the two guardrails 1 only need one sliding groove 205 of the pivot rod 204 to be aligned with the insertion groove 206 of the other pivot rod 204. Then, first move the movable plate 208 upward to its maximum limit position, and then move the movable plate 208 horizontally. At this time, the multiple insertion plates 207 installed on the movable plate 208 are respectively located below the corresponding positioning grooves 209. Then, move the movable plate 208 downward so that the multiple insertion plates 207 are respectively inserted into the corresponding positioning grooves 209 (e.g., ...). Figure 10 As shown in the figure, this enables a quick connection between the two guardrails 1, which is convenient and has good stability.

[0035] like Figure 1 and Figure 9As shown, in some embodiments, the limiting clip 4 includes a large gear 401, which is mounted on the rotating ring 202. One end of the limiting plate 3 has an arc-shaped toothed groove 402 for inserting into the tooth surface of the large gear 401. When the frame plate 203 rotates, it will drive the rotating ring 202 to rotate. As the rotating ring 202 rotates, the large gear 401 will also rotate. After the frame plate 203 has rotated, it is only necessary to move the limiting plate 3 so that the arc-shaped toothed groove 402 is inserted into the tooth surface of the large gear 401. Since the sliding plate is slidably set, when the sliding plate is inserted into the tooth surface of the large gear 401, the frame plate 203 can be limited. The design of the large gear 401 can ensure that the limiting plate 3 can be smoothly inserted into the tooth surface of the large gear 401. Moreover, when facing non-rectangular enclosures, the limiting plate 3 can also be well inserted into the tooth surface of the large gear 401, further improving its applicability.

[0036] like Figure 1 As shown, in some embodiments, the rotating component 5 includes an adjusting rod 501 vertically and rotatably mounted on the guardrail 1. Two movable plates 502 are symmetrically slidably mounted on the guardrail 1. Two connecting rods 503 are symmetrically hinged to the adjusting rod 501. The free ends of the two connecting rods 503 are respectively hinged to the two movable plates 502. The two movable plates 502 are respectively connected to two limiting plates 3. In this embodiment, when the adjusting rod 501 is rotated, the rotation of the adjusting rod 501 will drive the two connecting rods 503 hinged to it to rotate. Because one end of the connecting rod 503 is hinged to the movable plate 502, as the adjusting rod 501 rotates, the two movable plates 502 will move closer or further apart through the connecting rods 503. Because the movable plate 502 is connected to the limiting plate 3, the movement of the limiting plate 3 can be controlled by simply rotating the adjusting rod 501.

[0037] like Figure 1 and Figure 9 As shown, in some embodiments, a retaining spring 7 is installed between the limiting plate 3 and the guardrail 1. Under normal conditions, the retaining spring 7 keeps the limiting plate 3 tightly against the tooth surface of the large gear 401. In this embodiment, when the limiting plate 3 is inserted into the tooth surface of the large gear 401, the retaining spring 7 will keep the limiting plate 3 against the tooth surface of the large gear 401, thereby effectively preventing the limiting plate 3 from dislodging from the tooth surface of the large gear 401 when it is bumped by the outside, thus ensuring stability.

[0038] like Figure 1 and Figure 9As shown, in some embodiments, a metal plate 8 is installed on one end of the movable plate 502 near the corresponding limiting plate 3. One end of the limiting plate 3 has an installation groove 9, and a magnet 10 is installed in the installation groove 9. The limiting plate 3 is magnetically connected to the movable plate 502 via the magnet 10 and the metal plate 8. When the two movable plates 502 move away from each other to their maximum distance, the two limiting plates 3 overcome the magnetic force of the retaining spring 7 and are respectively attracted to the two metal plates 8, thus disengaging the two limiting plates 3 from the corresponding large gear 401. The guardrail 1 has a moving groove 11, and a baffle 12 located within the moving groove 11 is installed on the limiting plate 3. In this embodiment, the limiting plate 3 and the movable plate 502 are magnetically connected. When the adjusting rod 501 is rotated, causing the two movable plates 502 to move closer together to their maximum limit position, the metal plate 8 on the movable plate 502 approaches the magnet 10. This will cause the magnet 10 to adhere to the metal plate 8, thereby bringing the two limiting plates 3 closer together. It should be noted that the magnetic force between the magnet 10 and the metal plate 8 is greater than the elastic force of the clamping spring 7. Therefore, the clamping spring 7 is in a compressed state at this time. Since the moving plate 502 has moved to its maximum limit position, even if the adjusting rod 501 is released, the clamping spring 7 will not cause the moving plate 502 to move due to its own elastic deformation. Only when the two moving plates 502 are close to each other and the limiting plate 3 has moved to its maximum limit, as the moving plate 502 continues to move, the metal plate 8 on the moving plate 502 will separate from the magnet 10 on the limiting plate 3. Thus, under the elastic force of the clamping spring 7, the limiting plate 3 will abut against the tooth surface of the corresponding large gear 401. In this way, when adjusting the rotation angle of the frame plate 203, the rotation of the frame plate 203 can be effectively prevented from being affected by the clamping spring 7.

[0039] like Figure 1 , Figure 7 and Figure 10 As shown, in some embodiments, the bottom of the pivot rod 204 is concentrically constructed with a shaft 13 passing through the frame plate 203. A sleeve 14 is installed on the frame plate 203, and a positioning pin 15 is horizontally slidably installed at one end of the sleeve 14. One end of the positioning pin 15 is an outer arc surface. Two positioning recesses 16 are provided on the shaft 13 for the positioning pin 15 to be inserted. A spring is installed between the sleeve 14 and the positioning pin 15. Specifically, one of the positioning recesses 16 is connected to the sliding groove 20. Corresponding to 5, another positioning notch corresponds to the insertion slot 206. Thus, when multiple guardrails 1 are arranged into a rectangle, and it is necessary to ensure that the sliding grooves 205 of the two pivot rods 204 are aligned with the insertion slot 206, the positioning pin 15 can be sensed by rotating the pivot rod 204. This indicates that the sliding groove 205 or the insertion slot 206 has been rotated to the corresponding angle, which facilitates the subsequent insertion of the insertion plate 207 into the positioning slot 209.

[0040] like Figure 1 and Figure 9 As shown, in some embodiments, a small gear 403 that meshes with a large gear 401 is rotatably mounted on the guardrail 1. The arc-shaped toothed groove 402 is inserted into the tooth surface of the small gear 403. The design of the small gear 403 is such that when the frame plate 203 is rotated slightly, the large gear 401 on the frame plate 203 will also rotate slightly. However, because the large gear 401 meshes with the small gear 403, the small rotation of the large gear 401 will cause the small gear 403 to rotate significantly. Thus, when the limiting plate 3 cannot be inserted into the tooth surface of the small gear 403, only a small rotation of the large gear 401 is needed to allow the arc-shaped toothed groove 402 of the limiting plate 3 to be inserted into the tooth surface of the small gear 403, further improving the limiting accuracy.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
