Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to an explosion-proof radar switch. Background Technology

[0002] Explosion-proof radar switches are safety devices designed specifically for environments with explosion risks. They combine radar sensing with explosion-proof technology and can automatically control the opening or closing of electrical equipment when personnel or objects are detected approaching, ensuring that explosions will not occur due to sparks or other causes in flammable and explosive environments.

[0003] Currently, most explosion-proof radar switches are fixed to their desired positions using metal plates with mounting holes. The connection between the switch and the plate is achieved by threaded nuts passing through these holes. However, this method requires maintenance personnel to unscrew the nuts before removing the switch, which is prone to loss during operation due to the nut being separate from the switch. Furthermore, the entire process is time-consuming, increasing both the complexity of maintenance and reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof radar switch in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An explosion-proof radar switch includes a radar switch body, and a side plate and a bottom plate fixedly connected in an L-shape. The side plate has a U-shaped mounting groove for accommodating one end of the radar switch body. Locking nuts located on both sides of the side plate are threadedly connected to the radar switch body. The bottom plate is provided with a support plate for supporting the other end of the radar switch body. Single-headed tapered rods that move vertically are fixedly connected to both sides of the support plate.

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

[0008] A threaded sleeve is fixedly connected to the base plate, which is parallel to the single-headed tapered rod. A screw rod is screwed onto the threaded sleeve. The base plate has a first movable groove for accommodating the single-headed tapered rod and the screw rod. A second movable groove is connected between the two sets of first movable grooves. A double-headed tapered rod is slidably fitted in the second movable groove.

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

[0010] The bottom end of the screw has a conical structure, and the conical head at the bottom end of the screw and the conical head at the bottom end of the single-headed conical rod are respectively in sliding fit with the conical heads at both ends of the double-headed conical rod.

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

[0012] A guide sleeve fitted over the single-headed cone rod is fixedly connected to the base plate.

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

[0014] A level is embedded in the pallet.

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

[0016] The tray has an arc-shaped groove that mates with the radar switch body, and a soft pad is attached to the arc-shaped groove.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the radar switch body is accommodated by the side plate through the U-shaped assembly groove and is fixed by screwing in the locking nuts from both sides. This method simplifies the disassembly and assembly process of the radar switch body, eliminates the need to completely remove any parts, and reduces the risk of loss.

[0019] 2. In this utility model, by rotating the screw, the cone at the bottom of the screw and the cone at the bottom of the single-headed cone are respectively in sliding engagement with the cones at both ends of the double-headed cone, causing the double-headed cone to slide along the second movable groove, thereby adjusting the position of the single-headed cone, and thus adjusting the horizontal position of the radar switch body, ensuring that it is installed stably and in the best working state.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: an explosion-proof radar switch, including a radar switch body 1, and a side plate 3 and a bottom plate 4 fixedly connected in an L-shape. The side plate 3 has a U-shaped mounting groove 301 for accommodating one end of the radar switch body 1. The radar switch body 1 is connected to locking nuts 2 on both sides of the side plate 3 by threaded connection. The radar switch body 1 is accommodated by the side plate 3 through the U-shaped mounting groove 301 and fixed by the locking nuts 2 from both sides. This method simplifies the disassembly and assembly process of the radar switch body 1, eliminates the need to completely remove any parts, and reduces the risk of loss.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, the support plate 8 has an arc-shaped groove that mates with the radar switch body 1 to support the other end of the radar switch body 1. A soft pad 9 is attached to the arc-shaped groove, which ensures the stability of the fixation and provides buffer protection.

[0030] Specifically, such as Figure 2 and Figure 5As shown, single-headed conical rods 11 are fixedly connected to both sides of the support plate 8, located on both sides of the radar switch body 1. A guide sleeve 5 is fixedly connected to the bottom plate 4, sleeved outside the single-headed conical rods 11, and a screw sleeve 6 is arranged parallel to the single-headed conical rods 11. A screw rod 7 is screwed onto the screw sleeve 6. A first movable groove 401 is opened on the bottom plate 4 to accommodate the single-headed conical rods 11 and the screw rod 7. A second movable groove 402 is connected between the two sets of first movable grooves 401. A double-headed conical rod 12 is slidably fitted in the second movable groove 402. The bottom end of the screw rod 7 is a conical structure. When the screw rod 7 is rotated, the conical head at the bottom end of the screw rod 7 and the conical head at the bottom end of the single-headed conical rod 11 are slidably fitted with the conical heads at both ends of the double-headed conical rod 12, causing the double-headed conical rod 12 to slide along the second movable groove 402, thereby adjusting the position of the single-headed conical rod 11, realizing the height adjustment of the support plate 8 and the fine adjustment of the horizontality of the radar switch body 1.

[0031] Specifically, such as Figure 2 As shown, a level 10 is embedded in the support plate 8, which helps to observe and adjust the horizontal state of the radar switch body 1, ensuring the accuracy and stability of its installation.

[0032] Working principle: During installation, the radar switch body 1 is first placed in the U-shaped mounting groove 301 of the side plate 3 and initially fixed with the locking nut 2. Then, by rotating the screw 7, the cone at the bottom of the screw 7 and the cone at the bottom of the single-headed cone 11 slide with the cones at both ends of the double-headed cone 12, causing the double-headed cone 12 to slide along the second movable groove 402, thereby adjusting the position of the single-headed cone 11 and thus adjusting the horizontal position of the radar switch body 1, ensuring that it is installed stably and in the best working condition. During this process, the level 10 can help confirm whether the adjustment meets the requirements. During maintenance, the radar switch body 1 can be quickly removed for inspection or replacement simply by loosening the locking nut 2, greatly reducing maintenance time and complexity.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
