Description

Technical Field

[0001] This application relates to the field of radio frequency coaxial switch technology, and more specifically, to a fixed structure and a radio frequency coaxial switch. Background Technology

[0002] Radio frequency (RF) coaxial switches achieve control signal transmission paths through mechanical or electronic switching mechanisms. Using long-screw bolts to fix RF coaxial switches is a common installation method; each RF coaxial switch is typically secured with at least four bolts. However, due to the long bolt shafts, the installation and removal of RF coaxial switches using these long-screw bolts is slow and inefficient. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a fixed structure and a radio frequency coaxial switch, which aims to improve the problem of slow speed and low efficiency in disassembling and assembling radio frequency coaxial switches when using bolts with long screws.

[0004] This application provides a fixing structure, including a sleeve, a screw insertion part, and a screw connector.

[0005] The screw insertion part includes two half screw parts and an elastic support member. The inner side of the sleeve is provided with a limit groove. The elastic support member is disposed inside the limit groove and connected to the outer side of the upper section of the half screw part. A gap is reserved between the two half screw parts. A guide groove is provided at the top of the half screw part. An internal thread is provided on the upper edge of the inner side of the sleeve. The direction of the internal thread is consistent with the direction of the thread of the half screw part.

[0006] The screw connector is screwed into the sleeve, and a guide block is provided at the bottom of the screw connector to be inserted into the guide groove.

[0007] In one specific implementation, the semi-screw member includes a insert and a threaded section, the threaded section being disposed below the insert.

[0008] In one specific implementation, the elastic support includes a guide post and a spring, the guide post being fixedly disposed on the outer wall of the insertion rod, and the spring being disposed inside the limiting groove.

[0009] In one specific implementation, the outer side of the sleeve is provided with an external protrusion that communicates with the limiting groove, and the limiting groove extends into the interior of the external protrusion to install a spring.

[0010] In one specific implementation, the screw connector includes a pressure rod and a nut, the nut being fixed to the top of the pressure rod, and the upper section of the pressure rod being provided with an external thread that engages with the internal thread.

[0011] In one specific implementation, the guide block is integrally formed and disposed at the bottom end of the pressure rod.

[0012] In one specific implementation, the guide block and the guide groove are mating frustum-shaped structures.

[0013] This application also provides a radio frequency coaxial switch including the aforementioned fixed structure and a radio frequency coaxial switch body.

[0014] The radio frequency coaxial switch body includes a housing and a mounting plate. The mounting plate is sealed on the end face of the housing and has mounting holes. Two sets of semi-screw members are movably connected through the mounting holes.

[0015] Beneficial Effects: This application provides a fixing structure and an RF coaxial switch. Two pre-installed semi-screw members on the mounting plate can be directly inserted through mounting holes on the mounting plate into the threaded holes of the base. The screw connector is screwed into the sleeve. Rotating the screw connector presses the guide block at the bottom of the screw connector into the guide groove, causing the two semi-screw members to separate and engage with the threads of the threaded holes on the base. Continuing to rotate the screw connector drives the sleeve and the semi-screw members to rotate, allowing the semi-screw members to quickly engage with the threads of the threaded holes in the base. This fixing structure uses a shorter threaded structure instead of the original long threaded structure, enabling rapid rotational screwing for fixing or disassembly. Attached Figure Description

[0024] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0025] Please see Figures 1-6 This application provides a fixing structure, including a sleeve 1, a screw insertion part 2, and a screw connector 3.

[0026] The screw insertion part 2 includes two half-screw members 21 and an elastic support member 22. A limiting groove 11 is provided on the inner side of the sleeve 1. The elastic support member 22 is disposed inside the limiting groove 11 and connects to the outer side of the upper section of the half-screw member 21. A gap is reserved between the two half-screw members 21. A guide groove 23 is provided on the top of the half-screw member 21. An internal thread 12 is provided on the upper edge of the inner side of the sleeve 1, and the direction of the internal thread 12 is consistent with the direction of the thread of the half-screw member 21. The screw connector 3 is screwed into the sleeve 1, and a guide block 34 is provided at the bottom of the screw connector 3 to engage with the guide groove 23.

[0027] Sleeve 1 and half-screw members 21 are pre-formed. During installation, the two half-screw members 21 are pressed together by the elastic support member 22, causing their opposing surfaces to fit together. The two pre-installed half-screw members 21 on the mounting plate 42 can be directly inserted through the mounting holes 43 on the mounting plate 42 into the mating threaded holes of the base, with sleeve 1 acting as a limiting element. Then, the screw connector 3 is screwed into the sleeve 1. The thread length of the screw connector 3, which mates with the internal thread 12, is much shorter than the thread length of the half-screw member 21. That is, the distance of the external thread 32 is much shorter than the distance of the thread length of the thread segment 212. The thread distance is shorter when rotating the screw connector 3. Simultaneously, the guide block 34 at the bottom of the screw connector 3 presses into the guide groove 23, causing the two semi-screw members 21 to separate and engage with the threaded holes on the base (at this time, the limiting sleeve 1 needs to be supported by hand to prevent rotation). Continuing to rotate the screw connector 3 will cause the sleeve 1 and the semi-screw members 21 to rotate (at this time, the hand should be removed from the sleeve 1). The rotating screw connector 3 will cause the sleeve 1 and the semi-screw members 21 to rotate together, allowing the semi-screw members 21 to quickly engage with the threaded holes on the base. This fixing structure uses a shorter thread distance to replace the original long thread distance, enabling rapid rotational screw fixing or disassembly.

[0028] In a specific configuration, the semi-screw member 21 includes a plug rod 211 and a threaded section 212. The threaded section 212 is located below the plug rod 211 and is screwed into the threaded hole of the mounting base.

[0029] Specifically, the elastic support 22 includes a guide post 221 and a spring 222. The guide post 221 is fixedly disposed on the outer wall of the insertion rod 211, and the spring 222 is disposed inside the limiting groove 11. The spring 222 elastically supports the guide post 221, so that the two insertion rods 211 are relatively close together.

[0030] Furthermore, an outer protrusion 13 is provided on the outer side of the sleeve 1, which is connected to the limiting groove 11. The limiting groove 11 extends into the outer protrusion 13 to install the spring 222. The provision of the outer protrusion 13 increases the distance for installing the spring 222.

[0031] In the above specific embodiment, the screw connector 3 includes a pressure rod 31 and a nut 33. The nut 33 is fixed to the top of the pressure rod 31, and the upper section of the pressure rod 31 is provided with an external thread 32 that engages with the internal thread 12. The guide block 34 is integrally formed and provided at the bottom of the pressure rod 31. That is, rotating the nut 33 causes the pressure rod 31 to rotate, and the external thread 32 on the outer side of the pressure rod 31 engages with the internal thread 12, causing the guide block 34 to move along the axial position.

[0032] Furthermore, the guide block 34 and the guide groove 23 are inverted frustum-shaped structures that cooperate with each other.

[0033] This application also provides a radio frequency coaxial switch including the above-described fixing structure and a radio frequency coaxial switch body 4.

[0034] The RF coaxial switch body 4 includes a housing 41 and a mounting plate 42. The mounting plate 42 is disposed on the end face of the housing 41, and mounting holes 43 are provided on the mounting plate 42. Two sets of semi-screw members 21 are movably disposed through the mounting holes 43. This fixing structure is applicable to the mounting plates 42 of various RF coaxial switches, and is not limited to the square structure mounting plate 42 shown in the attached figure.

[0035] The working principle of this fixed structure and the RF coaxial switch is as follows: During installation, the two semi-screw members 21 are pressed together by the elastic support member 22, causing their opposing surfaces to fit together. The two semi-screw members 21 pre-installed on the mounting plate 42 can be directly inserted through the mounting holes 43 on the mounting plate 42 into the mating threaded holes of the base, with the sleeve 1 acting as a limit. Then, the screw connector 3 is screwed into the sleeve 1. The thread length of the screw connector 3 that mates with the internal thread 12 is much smaller than the thread length of the semi-screw member 21. That is, the distance of the external thread 32 is much smaller than the distance of the thread length of the thread segment 212. The thread distance is shorter when rotating the screw connector 3. Simultaneously, the guide block 34 at the bottom of the screw connector 3 presses into the guide groove 23, causing the two semi-screw members 21 to separate and engage with the threaded holes on the base. Continuing to rotate the screw connector 3 drives the sleeve 1 and the semi-screw members 21 to rotate together, allowing the semi-screw members 21 to quickly engage with the threads of the base's threaded holes. This fixing structure uses a shorter thread distance to replace the original long thread distance, enabling rapid rotational screw fixing or disassembly.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
