Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective housings, and more specifically, to a protective housing for an electric field sensor. Background Technology
[0002] Electric field sensors are widely used in intrusion detection systems. They detect intrusion by monitoring changes in the electric field within a specific area, thereby improving security. When using electric field sensors, a protective housing is required to protect the circuitry or sensor itself, ensuring that the electric field sensor can function properly.
[0003] Currently, most protective housings for electric field sensors have the following problems:
[0004] I. Existing electric field sensor protective housings are mostly used when the sensors are installed in a designated location and exposed to the outside. In order to avoid damage from bumps and knocks, most of them are protected by housings. The housings are mostly spliced together with bolts to protect the sensors. When it is necessary to disassemble the housing, disassembly is relatively troublesome, which makes it inconvenient to install and protect the sensors easily.
[0005] Second, the existing protective housings for electric field sensors are mostly fixed in size when installed, while the sensors come in different sizes and models. If the sensor is small, it is inconvenient to limit the sensor when it is installed in the housing. When protecting the sensor, the sensor is prone to shaking and bumping, and it is inconvenient to limit and clamp the sensor.
[0006] Therefore, we have made improvements to this by proposing a protective housing for electric field sensors. Utility Model Content
[0007] The purpose of this utility model is to address the current problems of inconvenient installation and protection of sensors, as well as inconvenience in limiting and clamping sensors.
[0008] To achieve the above objectives, the present invention provides the following technical solution:
[0009] A protective housing for the electric field sensor is provided to address the aforementioned issues.
[0010] The application is as follows:
[0011] The device includes a protective outer shell and a protective cover. The protective outer shell has a protective cover, and a fixed box is fixedly connected to the protective cover. A rotating rod is rotatably connected to the fixed box, and a first bevel gear is fixedly connected to the rotating rod. The first bevel gear meshes with a second bevel gear, and a transmission threaded rod is fixedly connected to the second bevel gear. The transmission threaded rod is rotatably connected inside the fixed box, and a clamp is threadedly connected to the transmission threaded rod. A protective pad is fixedly connected to the fixed box. A spring is fixedly connected inside the protective outer shell, and a support plate is fixedly connected to the other end of the spring. A sensor body is mounted on the support plate. A bidirectional threaded rod is rotatably connected to the protective outer shell, and a turntable is fixedly connected to the bidirectional threaded rod. A moving block is threadedly connected to the bidirectional threaded rod, and a clamping plate is fixedly connected to the moving block. A breathable mesh is fixedly connected to the protective outer shell.
[0012] As a preferred technical solution of this application, the inner side of the protective cover is in contact with the outer side of the protective shell, and the rotating rod is fixedly connected to the center of the first bevel gear.
[0013] As a preferred technical solution of this application, the second bevel gear is symmetrically distributed on the left and right sides of the first bevel gear, and the second bevel gear corresponds one-to-one with the card holder through the transmission thread rod.
[0014] As a preferred technical solution of this application, one end face of the card holder is in contact with the inner side of the fixed box, and the side face of the tray is in contact with the inner side of the protective shell.
[0015] As a preferred technical solution of this application, the spring is provided in two sets, and the two sets of springs are symmetrically distributed on the left and right sides inside the protective shell, with each set of springs being equidistantly distributed inside the protective shell.
[0016] As a preferred technical solution of this application, a transparent plate is fixedly connected to the protective shell, an isolation pad is fixedly connected to the protective shell, the movable blocks are symmetrically distributed on the left and right sides of the bidirectional threaded rod, and the movable blocks correspond one-to-one with the clamping plates.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In the scheme of this application:
[0019] 1. A fixed box is provided; when splicing the protective shell and the protective cover, the protective cover is placed on the protective shell, and the rotating rod drives the first bevel gear to rotate. The first bevel gear can drive the transmission threaded rod to rotate through the second bevel gear. When the transmission threaded rod rotates, it can push the two side brackets to move outward. The brackets can be locked in the protective shell and the protective cover, which can splice and fix them to prevent them from falling off. When disassembling, the transmission threaded rod is rotated in the opposite direction, which can remove the brackets and disassemble them, which facilitates the protection of the sensor body.
[0020] 2. Equipped with a bidirectional threaded rod; when limiting the sensor body for protection, the sensor body can be placed on the tray. After the protective cover is installed, the fixing box on the protective cover can press the sensor body. The sensor body is squeezed by the spring through the tray to limit the upper and lower positions. Rotating the turntable drives the bidirectional threaded rod to rotate. The bidirectional threaded rod can drive the two moving blocks on both sides to move inward at the same time. The clamping plates on the moving blocks clamp the sensor body from left to right, which can improve the stability of the limit installation. Attached Figure Description

[0033] Example 1:
[0034] like Figure 1-6 As shown, this embodiment proposes a protective housing for an electric field sensor, including a protective housing 1 and a protective cover 2. The protective cover 2 is provided on the protective housing 1, and a fixed box 3 is fixedly connected to the protective cover 2. A rotating rod 4 is rotatably connected to the fixed box 3, and a first bevel gear 5 is fixedly connected to the rotating rod 4. The first bevel gear 5 is meshed with a second bevel gear 6, and a transmission threaded rod 7 is fixedly connected to the second bevel gear 6. The transmission threaded rod 7 is rotatably connected inside the fixed box 3, and a clamp 8 is threadedly connected to the transmission threaded rod 7. A protective pad 9 is fixedly connected to the fixed box 3. A spring 10 is fixedly connected inside the protective housing 1, and a support plate 11 is fixedly connected to the other end of the spring 10. A sensor body 12 is provided on the support plate 11. A bidirectional threaded rod 13 is rotatably connected to the protective housing 1, and a turntable 14 is fixedly connected to the bidirectional threaded rod 13. A moving block 15 is threadedly connected to the bidirectional threaded rod 13, and a clamping plate 16 is fixedly connected to the moving block 15. A breathable mesh 19 is fixedly connected to the protective housing 1.
[0035] Example 2:
[0036] The solution in Example 1 will be further described below with reference to its specific working method.
[0037] like Figure 3 As shown, in a preferred embodiment, based on the above method, the inner side of the protective cover 2 is fitted with the outer side of the protective shell 1, and the rotating rod 4 is fixedly connected to the center of the first bevel gear 5, which can ensure that the protective cover 2 can be closed on the protective shell 1 for protection.
[0038] like Figure 3 As shown, in a preferred embodiment, based on the above method, the second bevel gear 6 is symmetrically distributed on the left and right sides of the first bevel gear 5. The second bevel gear 6 corresponds one-to-one with the bracket 8 through the transmission threaded rod 7, which can ensure that the brackets 8 on both sides can be engaged in the protective shell 1 and the protective cover 2 for splicing and fixing.
[0039] like Figure 6 As shown, in a preferred embodiment, based on the above method, one end face of the card holder 8 is in contact with the inner side of the fixed box 3, and the side face of the tray 11 is in contact with the inner side of the protective shell 1, which can ensure that the tray 11 can move smoothly through the contact of the inner side of the protective shell 1 when it moves up and down.
[0040] like Figure 3 As shown, in a preferred embodiment, based on the above method, two sets of springs 10 are further provided. The two sets of springs 10 are symmetrically distributed on the left and right sides inside the protective shell 1. Each set of springs 10 is equidistantly distributed inside the protective shell 1, which can ensure that multiple springs 10 can smoothly push the tray 11 to move.
[0041] like Figure 3 As shown, in a preferred embodiment, based on the above method, a transparent plate 17 is fixedly connected to the protective shell 1, an isolation pad 18 is fixedly connected to the protective shell 1, and movable blocks 15 are symmetrically distributed on the left and right sides of the bidirectional threaded rod 13. The movable blocks 15 correspond one-to-one with the clamping plates 16, which can ensure that the clamping plates 16 on both sides can clamp and limit the sensor body 12 from left to right.
[0042] Specifically, when using the protective housing of this electric field sensor: (in conjunction with...) Figure 1-6When splicing the protective shell 1 and the protective cover 2, the protective cover 2 is placed on the protective shell 1. The rotating rod 4 drives the first bevel gear 5 to rotate. The first bevel gear 5 can drive the transmission threaded rod 7 to rotate through the second bevel gear 6. When the transmission threaded rod 7 rotates, it can push the two side brackets 8 to move outward. The brackets 8 can be locked in the protective shell 1 and the protective cover 2, which can splice and fix them to prevent them from falling off. When disassembling, the transmission threaded rod 7 is rotated in the opposite direction, which can remove the brackets 8 and disassemble them, which facilitates the protection of the sensor body 12.
[0043] When limiting and protecting the sensor body 12, the sensor body 12 can be placed on the support plate 11. After installing the protective cover 2, the fixing box 3 on the protective cover 2 can press the sensor body 12, and the protective pad 9 on the fixing box 3 can play a protective role when pressing the sensor body 12. The sensor body 12 is squeezed by the spring 10 through the support plate 11 to limit its upper and lower position. Rotating the turntable 14 drives the bidirectional threaded rod 13 to rotate. The bidirectional threaded rod 13 can drive the two moving blocks 15 on both sides to move inward at the same time. The clamping plate 16 on the moving block 15 clamps the sensor body 12 from left and right, which can improve the stability of the limit installation. The ventilated mesh 19 on the protective shell 1 can play a role in ventilation and heat dissipation. The transparent plate 17 on the protective shell 1 makes it easy to observe the situation inside the protective shell 1. The isolation pad 18 is a flexible pad. Two isolation pads 18 are set. The two isolation pads 18 are fixed on the protective shell 1, and the contact surfaces of the two isolation pads 18 are in contact. When inserting the wire, the isolation pad 18 can be opened to insert the wire for connection.
