Description

Technical Field

[0001] This utility model relates to the field of band switch protection technology, specifically a protection device for combined band switch mechanisms. Background Technology

[0002] Combination band switches are common electrical control components widely used in various instruments and equipment to switch circuit channels and select signals. Because they contain multiple precision contacts and rotating structures, they are susceptible to damage from dust and impurities in the external environment during daily use, and may also be damaged or experience poor contact due to accidental impacts or liquid splashes. Therefore, appropriate protective measures need to be implemented for the band switch mechanism to ensure its long-term stable operation and extend its service life.

[0003] Existing protective devices typically have a simple sealing structure, making it difficult to achieve effective sealing at multiple moving and stationary interfaces simultaneously. This can easily lead to dust or moisture intrusion, affecting switch operation. Furthermore, the overall structural rigidity is insufficient, making it prone to deformation or loosening under complex operating conditions, thus reducing the reliability of the protection. Utility Model Content

[0004] The purpose of this invention is to provide a protection device for a combined band switching mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A protective device for a combined band switch mechanism includes an outer cover. An assembly plate is fixedly installed at the bottom of the outer cover. Four diagonal bracing ribs are installed at intervals at the angle where the assembly plate connects to the outer cover. The top of the diagonal bracing ribs is flush with the top of the outer cover, and each diagonal bracing rib has a fixing screw hole. The outer cover and the top of the diagonal bracing ribs are covered with a large sealing ring. A cover is fitted to the top of the large sealing ring. Four extension blocks are installed at intervals on the radially outer side of the cover. Each extension block has a fixing hole. A fixing screw is installed through the fixing hole, and the end of the fixing screw is connected to the fixing screw hole by a thread to fix the cover to the outer cover.

[0006] Preferably, four pads are formed by upward protrusions at intervals at the top edge of the assembly tray, and each pad has a through assembly hole in the middle.

[0007] Preferably, a wiring through hole is provided at the center of the bottom end of the assembly tray, and the wiring through hole is connected to the outer protective cover, and a sealing gasket is provided at the bottom edge of the assembly tray.

[0008] Preferably, the cap has a through hole in the middle, and the top of the cap has a groove at the opening of the through hole, and a small sealing ring is embedded in the groove.

[0009] Preferably, a locking screw ring is fitted at the top of the cover at the through hole, and the locking screw ring can be threadedly connected to the rotating seat of the band switch.

[0010] Preferably, the bottom end of the cover is symmetrically provided with limiting holes on both sides of the through hole, and a limiting rod for installing a band switch can be inserted into the limiting holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The protective device for this combined band switch mechanism significantly improves overall rigidity through the synergistic structure of the outer cover, diagonal bracing, and assembly plate, effectively resisting external mechanical impacts and vibrations. At the same time, the cover is locked to the top of the diagonal bracing through the fixing screw and the fixing screw hole, and the large sealing ring is pressed to achieve a highly reliable seal at the top of the device.

[0012] The protective device for this combined band switch mechanism achieves radial sealing of the rotating shaft through the cooperation of a small sealing ring and a locking screw at the through hole, and forms an interface seal by pressing the sealing gasket at the bottom of the assembly plate with the equipment mounting surface, together constructing a multi-layer sealing system that significantly enhances dustproof and waterproof capabilities.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: A protective device for a combined band switch mechanism includes an outer cover 101. An assembly plate 102 is fixedly installed at the bottom of the outer cover 101. Four diagonal bracing ribs 103 are installed at intervals at the angle between the assembly plate 102 and the outer cover 101. The top of the diagonal bracing ribs 103 is flush with the top of the outer cover 101, and each diagonal bracing rib 103 has a fixing screw hole 104. The top of the outer cover 101 and the top of the diagonal bracing ribs 103 are covered with a large sealing ring 105. A cover 106 is attached to the top of the large sealing ring 105. Four extension blocks 107 are installed radially outward from the cover 106 at intervals. Each extension block 107 has a fixing hole 108. A fixing screw 109 is installed through the fixing hole 108, and the end of the fixing screw 109 is connected to the fixing screw hole 104 by a thread to fix the cover 106 and the outer cover 101.

[0017] The above scheme provides physical protection for the internal band switch by providing a space for containment and isolation through the outer protective cover; it forms a mounting base at the bottom of the device through the assembly plate to achieve structural connection with external equipment; it connects the outer protective cover and the assembly plate through diagonal bracing to enhance the overall structural rigidity and resistance to deformation; it provides a threaded connection interface through the fixing screw hole to achieve reliable cooperation with the fixing screw; it covers the top of the outer protective cover and the diagonal bracing with a large sealing ring to form a top sealing plane; it seals the opening of the outer protective cover to form a protective cover; it provides a radial extension structure through the extension block to increase the distribution radius of the fixing hole; it accommodates the fixing screw through the fixing hole to provide an insertion channel; and it achieves a compression and sealing connection between the sealing cover and the outer protective cover by the fixing screw passing through the fixing hole and being threaded into the fixing screw hole.

[0018] In this embodiment, preferably, four pads 110 are formed by upward protrusions at intervals at the top edge of the assembly disk 102, and each pad 110 has a through assembly hole 111 in the middle.

[0019] The above scheme enhances the local compressive strength by raising the plane where the assembly hole is located by protruding the pad, and the mechanical fixation of the device to the equipment mounting surface is achieved by accommodating the mounting bolt through the assembly hole.

[0020] In this embodiment, preferably, a circuit through hole 112 is provided at the center of the bottom end of the assembly tray 102, and the circuit through hole 112 is connected to the outer protective cover 101, and a sealing gasket 113 is provided at the bottom edge of the assembly tray 102.

[0021] The above solution involves creating a through-hole at the center of the bottom of the assembly panel to provide a channel for the band switch cable to exit and maintain a clear path. A sealing gasket covers the bottom edge of the assembly panel to deform under pressure during device installation, thereby achieving an interface seal with the equipment mounting surface.

[0022] In this embodiment, preferably, the cover 106 has a through hole 114 in the middle, and the top of the cover 106 has a groove 115 at the opening of the through hole 114, and a small sealing ring 116 is embedded in the groove 115.

[0023] The above scheme uses a through hole at the center of the cover to allow the band switch rotary seat to pass through and be exposed. A groove surrounds the opening of the through hole to provide an embedded positioning structure for the small sealing ring. The small sealing ring is embedded in the groove to surround the outer wall of the rotary seat, thereby achieving a radial dynamic seal.

[0024] In this embodiment, preferably, a locking screw ring 117 is fitted at the top of the cover 106 at the through hole 114, and the locking screw ring 117 can be threadedly connected to the rotating seat of the band switch.

[0025] The above method involves using a locking ring to fit the top of the cover and connecting it to the rotating seat via threads to press the small sealing ring and lock the axial position of the rotating seat.

[0026] In this embodiment, preferably, limit holes 118 are symmetrically provided at the bottom end of the cover 106 and on both sides of the through hole 114, and a limit rod for installing a band switch can be inserted into the limit hole 118.

[0027] The above scheme achieves circumferential limiting and prevents rotation by symmetrically opening limiting holes on both sides of the bottom of the cover to accommodate the insertion of the limiting rod of the band switch.

[0028] In this embodiment, the protective device for the combined band switch mechanism uses an outer protective cover 101 as the main protective housing, providing basic spatial isolation and physical protection for the internal band switch. The assembly plate 102 is fixed to the bottom of the outer protective cover 101, serving as the installation interface between the entire device and external equipment. The four diagonal bracing ribs 103, which are spaced apart at the angle between the assembly plate 102 and the outer protective cover 101, not only enhance the overall structural rigidity but also provide reliable support for the fixing screw holes 104 at their tops. The tops of the diagonal bracing ribs 103 are flush with the tops of the outer protective cover 101, together forming a flat mounting reference surface.

[0029] The large sealing ring 105 covers the outer cover 101 and the top of the diagonal bracing rib 103, achieving the first end face seal when the cover 106 is pressed. The cover 106 cooperates with the fixing screw 109 passing through the fixing holes 108 on the four radially spaced extension blocks 107. The end of the fixing screw 109 is screwed into the fixing screw hole 104 at the top of the diagonal bracing rib 103. The cover 106 and the outer cover 101 are reliably connected by the threaded fastening, and the large sealing ring 105 undergoes elastic deformation during the pressing process to seal the joint surface.

[0030] The through hole 114 in the middle of the cover 106 is used to pass through the rotating seat of the band switch, and the small sealing ring 116 embedded in the groove 115 surrounds the outer wall of the rotating seat. The locking screw ring 117 is fastened to the rotating seat through the thread, pressing down the small sealing ring 116 to form a second radial seal; at the same time, the limiting rod of the band switch is inserted into the limiting hole 118 at the bottom of the cover 106 to achieve circumferential limiting of the switch and prevent it from rotating.

[0031] At the bottom of the device, the pad 110 at the top edge of the assembly plate 102 raises the plane where the assembly hole 111 is located, increasing the local pressure resistance at the connection. The assembly hole 111 is used to pass bolts through, fixing the entire device to the equipment mounting surface; the wiring through hole 112 at the bottom of the assembly plate 102 provides a lead-out channel for the band switch cable, and its size is such that the opening is minimized while ensuring the cable can pass through; the sealing gasket 113 is attached to the bottom edge of the assembly plate 102 and deforms under pressure when the device is tightened to the equipment mounting surface, achieving a third interface seal.

[0032] The entire device is rigidly supported by the outer protective cover 101 and the diagonal bracing 103. It uses a multi-layer sealing structure to block external dust, water vapor and other pollutants, and uses a mechanical locking and limiting structure to ensure that the band switch can still be reliably fixed and operate normally under the protection state.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
