[0002] A receiver is a device that can receive signals and convert them into useful information. It is usually used to receive electronic signals. Inductive receivers working in strong magnetic and electric field environments are subject to a large number of electrical and magnetic interference sources. Therefore, inductive receivers are usually used in conjunction with anti-interference detection devices. Common anti-interference detection devices on the market usually consist of a technical box and an antenna.

[0003] The antenna of the anti-interference detection device is usually set to a detachable mode. Although it is convenient for the storage of the detection device, the disassembly and assembly process is troublesome, and the disassembled antenna may be lost due to improper storage, affecting the overall use of the anti-interference detection device. Therefore, an anti-interference detection device of an inductive receiver is proposed to address the above problems. Utility Model Content

[0010] The advantages of the utility model are as follows: the utility model provides an anti-interference detection device for an inductive receiver. By providing a technical box, an antenna, a first groove, a limit block, a rotating shaft and a connecting block, a user can rotate the antenna when using the anti-interference detection device composed of the technical box and the antenna, so as to achieve the purpose of easy storage. Compared with the prior art of disassembling and storing the antenna, the disassembly and assembly process is saved, and at the same time, the loss of the disassembled antenna due to improper storage is avoided. By providing the second groove, the clamping block and the first spring, when the antenna rotates, it drives the rotating shaft to rotate in the limit block. When rotating, the clamping block is pressed down to the second groove provided on the rotating shaft. Inside, the first spring is compressed and rotated to a suitable position, and the elastic force of the first spring drives the inner wall of the card block and the limit block to fit closely together. Through the provided protective plate, fixed plate, limit plate, sliding rod, second spring and third groove, the fixed plate is pulled upward during use to drive the limit plate away from the first groove opened on the top of the technical box. At this time, the protective plate can be rotated. After rotating the protective plate, the antenna can be rotated and stored, and then the protective plate is rotated in the opposite direction to protect the stored antenna. Through the rubber layer set on one side of the protective plate, the protective plate has a slight buffering effect when it is fitted with the technical box, thereby increasing the protection effect on the antenna.

A third groove 15 is opened on the top of the technical box 1. A fixed plate 11 is tightly fitted on the top of the protective plate 10. A limiting plate 12 and a T-shaped sliding rod 13 are fixedly connected below the fixed plate 11. A second spring 14 is provided on the outside of the sliding rod 13. The rotatable mode of the antenna 2 is set, compared with the existing disassembly mode, it not only saves disassembly and assembly time, but also avoids the loss of the antenna 2.

[0027] Working process:

[0028] When the anti-interference detection device of the inductive receiver is in use, the anti-interference detection device composed of the technical box 1 and the antenna 2 is first placed in a suitable position, and the user holds the fixed plate 11 and moves it upward, driving the limit plate 12 and the sliding rod 13 to move upward at the same time, and the second spring 14 is compressed. When the limit plate 12 completely leaves the third groove 15 opened in the technical box 1, the protective plate 10 is rotated until it is in an open state, and then the antenna 2 in the first groove 3 opened in the technical box 1 is rotated. During the rotation, the antenna 2 and the connecting block 9 drive the rotating shaft 6 to rotate in the limit block 4. During the rotation, the card block 7 moves down to the second groove 5 opened in the rotating shaft 6 under the pressure of the inner wall of the limit block 4, and the first spring 8 is compressed. After rotating one hundred and eighty degrees, the antenna 2 is rotated to the top of the technical box 1.

Then the fixing plate 11 is pulled out to one side and the protective plate 10 is rotated in the opposite direction until the rubber layer 16 set on one side of the protective plate 10 is tightly fitted with the technical box 1, and the fixing plate 11 is released. Under the action of the elastic force of the second spring 14, the limit plate 12 moves down to the third groove 15, and the protective plate 10 is folded and stored. After the antenna 2 is used, the antenna 2 can be rotated and stored in the same way, and the protective plate 10 protects the antenna 2 after storage. The rotatable mode of the antenna 2 is set, compared with the existing disassembly mode, it not only saves the disassembly and assembly time, but also avoids the loss of the antenna 2. The protective device can effectively protect the antenna 2 after storage.
