Description

Technical Field

[0001] This utility model relates to the field of helmet technology, and in particular to a motorcycle helmet lens lock. Background Technology

[0002] A helmet is a tool to protect the head and is an indispensable tool for people in transportation, especially for motorcyclists and their passengers. Wearing a helmet can ensure the safety of people's lives. The front of the helmet usually has an opening, on which a visor is installed to ensure that the driver has good visibility and also to block wind, sand or dust.

[0003] A search revealed that Chinese utility model patent application CN202121207997.X discloses a locking structure for a helmet visor, comprising: a latch that can be laterally moved to a locked position and an unlocked position; a slider on the latch; a longitudinally movable actuating piece; and a slide rail that cooperates with the slider on the actuating piece. The slide rail has a first end and a second end, and is configured such that, by the longitudinal movement of the actuating piece, the slide rail can guide the latch to laterally move to the first end to reach the locked position, or to the second end to reach the unlocked position. Compared with the prior art, this utility model has a more planar driving structure for the latch, making it more suitable for embedding in the helmet shell. The actuating piece driving the latch can be stretched along the arc direction of the helmet, occupying less thickness and resulting in a more compact structure.

[0004] While the existing lens locking mechanism meets basic usage requirements, it is inconvenient to operate with one hand, and unlocking is cumbersome. Furthermore, operating it while the vehicle is in motion poses a significant safety hazard. Therefore, further improvements to the existing technology are necessary. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a motorcycle helmet lens lock that addresses the above-mentioned deficiencies of the prior art. The lens is locked by setting a switch button that works in conjunction with the lens lock hook. To unlock, simply press the switch button to disengage the lens lock hook from the lock hook groove. This can be operated with one hand, making it more convenient and improving the safety of unlocking.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A motorcycle helmet visor lock includes a switch button, a visor locking hook, a visor locking inner cover, and an inner cover fixing plate. The visor locking hook is disposed at the end of the visor. The inner cover fixing plate is installed at the front end of the helmet body. The visor locking inner cover is installed on the inner cover fixing plate. The switch button is installed at the front end of the visor locking inner cover and is rotatably connected to the visor locking inner cover. The front end of the switch button has a locking hook groove that matches the visor locking hook. The visor locking hook is engaged with the inner side of the locking hook groove.

[0008] Preferably, the inner cover fixing plate has a button through hole adapted to the switch button, and the switch button passes through the button through hole and is connected to the lens lock inner cover.

[0009] Preferably, the bottom of the switch button is provided with a first rotating foot, and a rotating shaft is provided on the outer side of the first rotating foot. The bottom of the inner cover of the lens lock is provided with a second rotating foot, and a rotating shaft through hole adapted to the rotating shaft is opened on the second rotating foot, and the rotating shaft is inserted into the rotating shaft through hole.

[0010] Preferably, the inner cover of the lens lock is provided with a spring mounting post, and the spring mounting post is provided with a spring, which abuts against the inner cover of the lens lock and the switch button respectively.

[0011] Preferably, the front end of the switch button is provided with an outwardly protruding pressing part.

[0012] Preferably, the inner cover of the lens lock has several screw through holes, and the inner cover of the lens lock is connected to the inner cover fixing plate by screws.

[0013] By adopting the above technical solution, the motorcycle helmet visor lock provided by this utility model has the following beneficial effects: the visor locking hook in the motorcycle helmet visor lock is set at the end of the visor, the inner cover fixing plate is installed at the front end of the helmet body, the inner cover of the visor lock is installed on the inner cover fixing plate, the switch button is installed at the front end of the inner cover of the visor lock and is rotatably connected to the inner cover of the visor lock, and the front end of the switch button has a locking hook groove that matches the visor locking hook. The visor locking hook is engaged with the inner side of the locking hook groove. By setting the switch button to cooperate with the visor locking hook, the visor can be locked. When unlocking, simply press the switch button to disengage the visor locking hook from the locking hook groove. It can be operated with one hand, making it more convenient to operate and improving the safety of unlocking while riding. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] like Figure 1-3As shown, the motorcycle helmet visor lock includes a switch button 1, a visor lock hook 2, a visor lock inner cover 3, and an inner cover fixing plate 4. The visor lock hook 2 is located at the end of the visor 5. The inner cover fixing plate 4 is installed at the front end of the helmet body 6. The visor lock inner cover 3 is installed on the inner cover fixing plate 4. The switch button 1 is installed at the front end of the visor lock inner cover 3 and is rotatably connected to the visor lock inner cover 3. The front end of the switch button 1 has a lock hook groove 7 that matches the visor lock hook 2, and the visor lock hook 2 is engaged with the inner side of the lock hook groove 7. It can be understood that the visor 5 is rotatably installed on the helmet body 6, which can be a general helmet, etc. The front end of the helmet body 6 may have an inner cover fixing plate mounting groove that matches the inner cover fixing plate 4 for fixing the inner cover fixing plate 4.

[0022] Specifically, the inner cover fixing plate 4 has a button through hole 8 adapted to the switch button 1. The switch button 1 passes through the button through hole 8 and is connected to the lens lock inner cover 3. The bottom of the switch button 1 is provided with a first rotating support leg 9, and the outer side of the first rotating support leg 9 is provided with a rotating shaft 10. The bottom of the lens lock inner cover 3 is provided with a second rotating support leg 11. The second rotating support leg 11 has a rotating shaft through hole 12 adapted to the rotating shaft 10. The rotating shaft 10 is inserted into the rotating shaft through hole 12.
