[0002] Terahertz waves refer to electromagnetic waves with a frequency range of 0.1 to 1.0 terahertz. Terahertz waves are a spectrum between microwaves and infrared rays. Due to their special properties, they are widely used in scientific research, communications, imaging, security detection and other fields.

[0003] A terahertz generator is often composed of a generator and a generator tube. The terahertz generator generates terahertz waves, which are then transmitted through the generator tube. However, the range of electromagnetic waves emitted by terahertz waves is often directly related to the diameter of the generator tube. The larger the diameter of the generator tube, the larger the range of terahertz waves when radiating from the generator tube. The smaller the diameter of the generator tube, the smaller the range of terahertz waves when radiating from the generator tube. During the use of the terahertz microwave generator, it is often necessary to adjust the range of terahertz waves according to actual conditions, and the adjustment of the diameter of the generator tube often requires the replacement of a new generator tube, which is more troublesome.

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] according to Figure 1-5 As shown: the utility model provides a terahertz microwave generating device: comprising a support seat 1, the support seat 1 is fixedly connected with a fixed cylinder 2 upward; a slide groove 3 is provided in the fixed cylinder 2, and a sliding block 4 is slidably arranged in the slide groove 3; the sliding block 4 is fixedly connected with a support plate 9 and a terahertz wave generator 5 upward in sequence, and a generating tube 6 is arranged on one side of the terahertz wave generator 5; a fixed block 13 is fixedly provided on one side of the support plate 9, a rotating groove 17 is provided in the fixed block 13, and a rotating block 19 is rotatably arranged in the rotating groove 17; an operating rod 11 is fixedly connected to one side of the rotating block 19, and a rotating plate 8 is fixedly sleeved on the operating rod 11; a groove 7 is provided in the generating tube 6, and a part of the rotating plate 8 is located in the groove 7; the rotating plate 8 is provided with circumferentially distributed adjusting holes 10, and the center of one adjusting hole 10 corresponds to the center of the generating tube 6. The rotating block 19 is provided with circumferentially distributed fixing holes 18, and a fixing rod 22 is provided in the fixing block 13, and the fixing rod 22 is inserted into the fixing hole 18.

[0022] When the rotating plate 8 is driven to rotate by the operating rod 11, adjustment holes 10 of different sizes can be located in the groove 7, and the center of the adjustment hole 10 can correspond to the center of the generating tube 6, so that the diameter of the generating tube 6 can be quickly replaced without disassembling the generating tube 6.

[0023] The number of the fixing holes 18 is the same as that of the adjusting holes 10 , and the circumferential distribution angular intervals of the fixing holes 18 on the rotating block 19 are the same as the circumferential distribution angular intervals of the adjusting holes 10 on the rotating plate 8 .

[0024] The distribution of the fixing holes 18 corresponds to the distribution of the adjusting holes 10, which can ensure that when different adjusting holes 10 are rotated to the center of the generating tube 6, the corresponding fixing holes 18 can also be rotated to a position aligned with the spring groove 21, thereby facilitating the fixation of the rotating plate 8 after replacing the adjusting holes 10.

[0025] A spring groove 21 is provided in the fixed block 13, and the fixed rod 22 is located in the spring groove 21; a limit ring 20 fixedly sleeved on the fixed rod 22 is provided in the spring groove 21, and a compression spring 23 sleeved on the fixed rod 22 is provided in the spring groove 21; the compression spring 23 has a reserved compression amount, which can enable the compression spring 23 to continuously exert pressure on the limit ring 20, thereby ensuring that the fixed rod 22 will not detach from the fixed hole 18 in the absence of external force, thereby ensuring the stability of the fixation of the rotating block 19.

[0026] A lifting motor 14 is arranged in the chute 3, and a screw rod 15 is fixedly connected to the output shaft of the lifting motor 14; a lifting plate 16 fixedly connected to the sliding block 4 is threadedly connected to the screw rod 15. The chute 3 is square, and the lifting plate 16 is a square corresponding to the chute 3, and the lifting plate 16 fits the inner wall of the chute 3.

[0027] The arrangement of the square slide groove 3 and the lifting plate 16 can limit the rotation of the lifting plate 16 , thereby converting the rotation of the screw rod 15 into the movement of the lifting plate 16 and driving the sliding block 4 to slide up and down.

[0028] The bottom of the support seat 1 is provided with wheels 12; the rotating plate 8 is coated with electromagnetic wave shielding paint.

[0029] The arrangement of the wheels 12 facilitates the movement of the entire device. At the same time, the electromagnetic wave shielding paint can ensure that the terahertz wave does not penetrate the rotating plate 8, thereby ensuring the practical usability of the adjustment hole 10.

[0030] Principle of the utility model

[0031] like Figure 1-2 The following is a state diagram of the normal operation of the terahertz microwave generator: Figure 3 As shown, the height position of the terahertz wave generator 5 can be adjusted. The lifting motor 14 is started, and driven by the lifting plate 16, the sliding block 4 drives the support plate 9 and the terahertz wave generator 5 to slide up and down, so that the height of the terahertz wave generator 5 can be adjusted.

[0032] like Figure 4-5As shown, when it is necessary to adjust the range of the terahertz wave emitted from the generating tube 6, it is only necessary to pull the fixing rod 22 out of the fixing hole 18, at which time the limit ring 20 compresses the compression spring 23; the operating rod 11 can be operated to drive the rotating plate 8 to rotate, so that the adjustment hole 10 of the appropriate size is located in the groove 7, and at the same time the rotating block 19 rotates in the rotating groove 17, and the corresponding fixing hole 18 is also aligned with the spring groove 21, and the fixing rod 22 is loosened. Under the left and right of the rebound force of the compression spring 23, the fixing rod 22 is inserted into the fixing hole 18, thereby completing the fixation of the rotating block 19, and also ensuring that the rotating plate 8 will not rotate again. At this time, it can be ensured that the range of electromagnetic waves emitted by the terahertz wave generator 5 corresponds to the aperture of the adjustment hole 10. Therefore, when changing the range of the terahertz wave emitted from the generating tube 6, the present application does not need to replace the generating tube 6 of different diameters, but only needs to rotate the rotating plate 8 to align different adjustment holes 10 with the generating tube 6, which is simple and fast.

[0033] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
