Description

Technical Field

[0001] This utility model belongs to the field of helmets, and specifically relates to a motorcycle helmet. Background Technology

[0002] A motorcycle flip-up helmet structure includes a helmet body and a chin guard hinged to the front of the helmet body. The chin guard can be flipped up to the top of the helmet body for ventilation, or it can be flipped down to protect the chin. Traditionally, the chin guard, when flipped down, is usually connected to the helmet body via a hook assembly. The disadvantages of this assembly are that it is relatively complex, prone to loosening, and lacks security. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a motorcycle helmet with a simple structure and better stability and a safety buckle.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a helmet body, a chin guard rotatably connected to the rotating shafts on both sides of the helmet body, a locking disc concentrically arranged on both sides of the chin guard, a locking groove at the lower end of the locking disc, a slidable locking pin on both sides of the chin guard, and a lock head that engages with the locking groove at the front end of the locking pin.

[0005] The locking pin is slidably disposed in the first sliding groove on both sides of the jaw guard and a second sliding groove is provided in the middle. The jaw guard is provided with a positioning block that slides with the second sliding groove.

[0006] The upper end of the second slide is provided with a spring mounting post, and a spring is provided between the spring mounting post and the positioning block.

[0007] The rear end of the lock slot is provided with a pull handle, and the pull handle is provided with a finger hole.

[0008] The chin guard has arc-shaped positioning grooves on both sides, and positioning posts on both sides of the helmet body are positioned and cooperate with the arc-shaped positioning grooves.

[0009] The helmet body has an inclined guide surface in front of the positioning post, and the top of the guide surface abuts against the locking disc.

[0010] The locking disc is connected to the rivet holes on both sides of the jaw guard via two rivet posts at the bottom.

[0011] The advantages of this motorcycle helmet with a safety buckle are: the chin guard is connected to the helmet body by a locking pin, making the connection safer and more reliable, and making locking and unlocking more convenient.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0013] Figure 1 This is a structural schematic diagram of the motorcycle helmet of this utility model; Figure 2 This is a partial structural diagram of the jaw guard of this utility model; Figure 3 This is a partial exploded view of the jaw guard of this utility model; Figure 4 This is a schematic diagram of the locking pin structure of this utility model; Figure 5 This is a magnified view of a portion of the main structure of the helmet of this utility model. Detailed Implementation

[0014] like Figures 1 to 5 As shown, the motorcycle helmet with a safety buckle of this utility model includes a helmet body 1 and a chin guard 3 rotatably connected to pivots 2 on both sides of the helmet body 1. The chin guard 3 has locking discs 4 concentrically arranged on both sides of the pivots 2. The lower end of each locking disc 4 has a locking groove 5, and the chin guard 3 has slidable locking pins 6 on both sides, with a locking head 7 at the front end of each locking pin 6 that engages with the locking groove 5.

[0015] Preferably, the locking pin 6 is slidably disposed within the first sliding grooves 8 on both sides of the jaw guard 3, and the locking pin 6 has a second sliding groove 9 in the middle. The jaw guard 3 is provided with a positioning block 10 that slides with the second sliding groove 9. With the above structure, the locking pin 6 can slide very stably at both ends of the jaw guard 3.

[0016] Preferably, a spring mounting post 11 is provided at the upper end of the second slide groove 9, and a spring 12 is provided between the spring mounting post 11 and the positioning block 10. The spring 12 enables the automatic reset of the locking pin 6.

[0017] Preferably, the rear end of the lock groove 5 is provided with a pull handle 13, and the pull handle 13 is provided with a finger hole 14. The user can slide the lock pin 6 by hooking his finger into the finger hole 14 to facilitate unlocking.

[0018] Preferably, the chin guard 3 has arc-shaped positioning grooves 15 on both sides, and positioning posts 16 on both sides of the helmet body 1 that engage with the arc-shaped positioning grooves 15 for positioning the chin guard 3 after it has been rotated into place.

[0019] Preferably, the helmet body 1 has an inclined guide surface 17 in front of the positioning post 16, and the top of the guide surface 17 abuts against the locking disc 4. The guide surface 17 enables the locking disc 4 to rotate more stably.

[0020] Preferably, the locking disc 4 is connected to the rivet holes 19 on both sides of the jaw guard 3 via two rivet posts 18 at the bottom for easy assembly.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
