Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer structure. Background Art

[0002] The mixer's local oscillator's second harmonic frequency operates between 109.5 and 115.5 GHz. The mixer is fabricated using a hybrid integration process. It consists of a waveguide transition—a microstrip line—and two beam-lead mixing diodes. Mixer structures are often used in high-frequency signal processing.

[0003] After searching, the patent document with publication number CN115498385A discloses a terahertz matching filter integrated mixer structure, which belongs to the field of terahertz device technology. It includes a gold-wire intermediate frequency microstrip line, an intermediate frequency matching filter integrated microstrip line, a local oscillator waveguide-microstrip probe transition structure, a local oscillator matching filter integrated microstrip line, a diode, a radio frequency matching circuit, a radio frequency waveguide-microstrip probe transition structure and a radio frequency grounding circuit. Although it has the advantage of good physical stability, it still has the following disadvantages to a certain extent.

[0004] For example, the aforementioned terahertz matched filter integrated mixer structure does not have a fixing bolt auxiliary ejection mechanism during the disassembly and assembly process. This can easily lead to disassembly being hindered due to rust on the fixing bolts, causing certain inconveniences for the user's maintenance. In order to solve the above technical problems, we have designed a mixer structure. Utility Model Content

[0005] The purpose of the utility model is to provide a mixer structure, which has the advantage that the disassembly efficiency is not affected after the fixing bolts are corroded, and solves the problem that the fixing bolts are easily corroded and the disassembly efficiency is affected.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mixer structure, comprising a mixer body, a fixed vertical plate welded to the top of the mixer body, an auxiliary pop-up mechanism provided on the top of the mixer body, the auxiliary pop-up mechanism comprising a movable plate, and fixing rods penetrating both the front and rear sides of the right side of the movable plate, a passive heat dissipation mechanism provided at the bottom of the mixer body, and an identification plate embedded in the top of the mixer body.

[0007] Preferably, the four corners on the left side of the fixed vertical plate are each provided with a second through hole, and the four corners on the rear side of the fixed vertical plate are each provided with a first through hole.

[0008] Preferably, a groove is provided at the bottom of the mixer body, the passive heat dissipation mechanism includes heat dissipation fins, the tops of the heat dissipation fins are welded to the top of the groove cavity, and heat dissipation side holes are provided on both sides of the bottom of the mixer body.

[0009] Preferably, a skid-mounted shell is welded at the center of the right side of the movable plate, the left side of the fixing rod is welded to the fixed vertical plate, and the right side of the fixing rod is welded to a limiting block.

[0010] Preferably, a return spring is provided on the left movable sleeve on the surface of the fixed rod, the left side of the return spring is welded to the fixed vertical plate, and the right side of the return spring is welded to the movable plate.

[0011] Preferably, fixing bolts are provided on both the front and rear sides of the right center of the movable plate, a connecting gasket is provided on the left movable sleeve of the surface of the fixing bolt, and a sliding hole for use with the fixing bolt is opened on the left side of the fixed vertical plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model cooperates with the heat dissipation side hole, the identification nameplate, the first through hole, the fixed vertical plate, the fixing rod, the reset spring, the sliding hole, the prying shell, the fixing bolt, the limit block and the second through hole. During use, the fixing bolt can be loosened to eliminate the large limit locking effect. The reset spring can slowly squeeze out the fixing bolt through the elastic force generated by the recovery deformation. If the fixing bolt cannot be loosened at all, the user can pry off the prying shell with a prying tool, thereby completing the removal of the fixing bolt. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figure 1-Figure 3A mixer structure includes a mixer body 1, a fixed vertical plate 5 is welded to the top of the mixer body 1, an auxiliary pop-up mechanism 18 is provided on the top of the mixer body 1, and the auxiliary pop-up mechanism 18 includes a movable plate 15. Fixed rods 6 are provided on both the front and rear sides of the right side of the movable plate 15. A passive heat dissipation mechanism 17 is provided at the bottom of the mixer body 1, and an identification nameplate 3 is embedded in the top of the mixer body 1. By setting the identification nameplate 3, the data of the mixer can be identified for the user to check it.

[0019] See also Figure 2 The four corners on the left side of the fixed vertical plate 5 are each provided with a second through hole 12 , and the four corners on the rear side of the fixed vertical plate 5 are each provided with a first through hole 4 .

[0020] See also Figure 2 A groove 13 is provided at the bottom of the mixer body 1, and the passive heat dissipation mechanism 17 includes a heat dissipation fin 14, the top of the heat dissipation fin 14 is welded to the top of the inner cavity of the groove 13, and heat dissipation side holes 2 are provided on both sides of the bottom of the mixer body 1.

[0021] See also Figure 2 A skid-mounted shell 9 is welded at the center of the right side of the movable plate 15. By setting the skid-mounted shell 9, when the reset spring 7 cannot provide disassembly assistance, it is convenient for the staff to pry it with other tools. The left side of the fixed rod 6 is welded to the fixed vertical plate 5, and the right side of the fixed rod 6 is welded with a limiting block 11. By setting the limiting block 11, the movable plate 15 can be limited to prevent it from falling off the surface of the fixed rod 6.

[0022] See also Figure 2 The left movable sleeve on the surface of the fixed rod 6 is provided with a reset spring 7, the left side of the reset spring 7 is welded to the fixed vertical plate 5, and the right side of the reset spring 7 is welded to the movable plate 15.

[0023] See also Figure 3 , fixing bolts 10 are provided on both sides of the front and rear of the right center of the movable plate 15, and a connecting gasket 16 is provided on the left movable sleeve of the surface of the fixing bolt 10. By providing the connecting gasket 16, the connection stability between the movable plate 15 and the fixed vertical plate 5 can be increased, thereby avoiding damage to the installation effect due to the existence of a connection gap. A sliding hole 8 for use with the fixing bolt 10 is opened on the left side of the fixed vertical plate 5.

[0024] During use, when the mixer body 1 needs to be disassembled, the user first observes whether the fixing bolts 10 are rusted. If no rust occurs, the corresponding fixing bolts 10 can be directly unscrewed with a screwdriver. If rust occurs and the screwdriver cannot be unscrewed well, the fixing bolts 10 can be loosened so that they no longer have a large limit locking effect. The reset spring 7 can slowly squeeze out the fixing bolts 10 through the elastic force generated by the recovery deformation. If the fixing bolts 10 cannot be loosened at all, the user can use a prying tool to pry off the prying shell 9 to complete the disassembly of the fixing bolts 10. During the operation of the mixer body 1, the heat generated can be quickly discharged through the heat dissipation fins 14, thereby avoiding heat accumulation affecting the service life of the mixer body 1.

[0025] In summary, the mixer structure solves the problem of easy rusting of fixing bolts and thus affecting disassembly efficiency through the coordinated use of the heat dissipation side hole 2, the identification nameplate 3, the first through hole 4, the fixed vertical plate 5, the fixing rod 6, the return spring 7 and the sliding hole 8.
