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.
[0023] This utility model provides a technical solution:
[0024] Figure 1-3 One embodiment is shown: a gearless waterproof throttle knob, including a housing 1 and a rotating base 2, the housing 1 and the rotating base 2 are connected by a positioning mechanism, the positioning mechanism includes a positioning ring block 3 disposed on the housing 1, the rotating base 2 is provided with a positioning groove 4 for the positioning ring block 3 to be positioned and engaged, the positioning ring block 3 is provided with a first sealing groove 5, and a first sealing gasket 6 is disposed in the first sealing groove 5; a protective sleeve 7 is provided inside the housing 1, a rotating shaft 8 is provided inside the protective sleeve 7, a second sealing groove 9 is provided on the rotating shaft 8, and a second sealing gasket 10 is disposed in the second sealing groove 9; The rotating shaft 8 is connected to the rotating base 2 via a detachable mechanism. The detachable mechanism includes a sealing cover 11 with a diameter larger than that of the rotating shaft 8. The sealing cover 11 is connected to the rotating shaft 8 via screws 12, allowing the rotating shaft 8 to rotate with the rotating base 2. The top of the rotating base 2 is provided with a third sealing groove 13, and a third sealing gasket 14 is provided inside the third sealing groove 13. The bottom of the outer shell 1 is provided with a rear cover plate 15 to close the outer shell 1, and an inwardly recessed groove 16 is formed between the rear cover plate 15 and the outer shell 1. The groove 16 is filled with a filler 17 that can seal the gap.
[0025] The bottom of the rotating shaft 8 is provided with a rotating base 18 with a diameter larger than that of the rotating shaft 8. The bottom of the rotating base 18 is provided with an embedded groove 19, and a magnet 20 is provided in the embedded groove 19.
[0026] Among them, a sealing plate 21 is provided between the sealing cover 11 and the rotating base 2 to seal and compact the third sealing gasket 14.
[0027] The outer casing 1 contains a circuit board 22, which is a Hall effect circuit board 22.
[0028] The outer shell 1 is fixed with a mating component that rotates with the rotating base 2 by bolts 35. The mating component includes a fixed base 23, a storage groove 24 set on the fixed base 23, a sliding steel ball 25 set in the storage groove 24, and a spring 26 set between the sliding steel ball 25 and the storage groove 24. The rotating base 2 is provided with a slot 27 that mates with the mating component. The slot 27 is provided with an internal toothed washer 28 that mates with the sliding steel ball 25. The internal toothed washer 28 that mates with the wobbling steel ball is set with an arc angle of 110° and is symmetrical from left to right.
[0029] The rotating base 2 is provided with a knob housing 29 by means of a locking mechanism. The locking mechanism includes an elastic locking strip 30 that is provided on the rotating base 2 and protrudes outward. The knob housing 29 is provided with a limiting locking groove 3127 that cooperates with the elastic locking strip 30, which facilitates the disassembly of the knob housing 29 and can drive the rotating base 2 to rotate.
[0030] The rotating base 2 can be freely moved with the help of the knob housing 29. After rotating a certain angle, it will not rotate freely due to the tooth groove on the internal toothed washer 28.
[0031] The outer casing 1 is provided with a mounting plate 32 for fixing the outer casing 1.
[0032] The outer casing 1 is provided with a power cord 33 that is connected to the circuit board 22, and the power cord 33 is provided with a power plug 34 that can be electrically connected to an external power source.
[0033] The filler 17 is made of epoxy resin, which is an existing technology material.
[0034] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0035] In use, the first sealing gasket 6, the second sealing gasket 10, the third sealing gasket 14, and the epoxy resin filler 17 can seal the gaps between the rotating base 2 and the outer shell 1, the gaps between the rotating shaft 8 and the protective sleeve 7, the gaps between the sealing plate 21 and the rotating base 2, and the gaps created after the rear cover plate 15 seals the outer shell 1. This effectively improves the waterproof effect and prevents rainwater from seeping into the outer shell 1 and causing short circuits in the circuit board 22 under harsh conditions such as rain. When the knob shell 29 drives the rotating base 2 to rotate, the rotating shaft 8 can rotate with the rotating base 2, causing the magnet 20 set in the embedded groove 19 to rotate synchronously, thus demonstrating that the knob has no gear position and can be rotated freely. When the rotating base 2 is not rotating, the rotating base 2 will not rotate freely due to the cooperation of the internal toothed washer 28, the sliding steel ball 25, and the spring 26.
