DETAILED DESCRIPTION

[0020] The following is combined with Figure 1 -Attached Figure 5 The utility model is further described in detail:

[0021] The utility model discloses an electric vehicle helmet lock that is easy to install. Figure 1 、 Figure 3 As shown, the utility model is an easy-to-install electric vehicle helmet lock, comprising a lock body 1. The bottom of the lock body 1 is provided with a clamp 2 for fixing to the handlebars. The interior of the lock body 1 is provided with an elastic limiting assembly for limiting the clamp 2. The top of the lock body 1 is integrally formed with a connecting column 3. The interior of the connecting column 3 is plugged with a locking pin 4. The connecting column 3 can lock the helmet strap through the locking pin 4. The top of the lock body 1 is provided with a cam lock core 5. When the cam lock core 5 is locked, it can simultaneously limit the elastic limiting assembly and the locking pin 4. In this embodiment, the lock body 1 is fixed to the handlebars via the clamp 2. The helmet strap is placed on the locking pin 4, and the locking pin 4 is then inserted into the connecting column 3. The cam lock core 5 is closed with a key to complete the simultaneous fixing of the helmet and the lock body 1. The cam lock core 5 is a common locking structure in the prior art. The rear lock tongue can be rotated by a key. The key can only be removed when the cam lock core 5 is in the closed state.

[0022] like Figure 2 As shown, the side wall of the lock body 1 is provided with an arcuate groove 6 for cooperating with the clamp 2. One end of the clamp 2 is integrally formed with the side wall of the lock body 1, and the other end of the clamp 2 can be inserted into the arcuate groove 6 and slide in the arcuate groove 6. In this embodiment, the clamp 2 can be made of metal, rubber or plastic, as long as it can produce a certain degree of deformation so that the clamp 2 can be inserted into the handlebar. The specific shape of the clamp 2 is as follows Figure 2 As shown, by providing the clamp 2, the lock body 1 can be installed on any electric vehicle with different handlebars, thereby enhancing versatility.

[0023] like Figure 2 、 Figure 3As shown, the elastic limiting assembly includes a limiting pin 71 and a limiting spring 72; a through hole 73 is provided inside the lock body 1, and the through hole 73 is internally connected to the arc groove 6, and a limiting pin 71 is provided in the through hole 73. The side wall of the limiting pin 71 is integrally formed with an annular flange 711, and the inner wall of the through hole 73 is fixedly connected to one end of the limiting spring 72, and the other end of the limiting spring 72 is fixedly connected to the top wall of the annular flange 711. The outer wall of the clamp 2 is provided with a plurality of limiting grooves 21 that match the limiting pin 71; in this embodiment, when the tongue lock cylinder 5 is locked, the lock tongue will be on the upper side of the limiting pin 71. At this time, the moving space of the limiting pin 71 is limited, and the fastening state of the clamp 2 cannot be released. At this time, the lock body 1 cannot be removed from the handlebar. The specific shapes of the limiting pin 71 and the through hole 73 are as shown in the figure. Figure 2 As shown, the through hole 73 is a multi-section hole with different inner diameters. The inner diameter of the middle part of the through hole 73 is larger than the two ends of the through hole 73. The limit pin 71 is slidably connected in the through hole 73 through the annular flange 711. The limit spring 72 pushes the annular flange 711 to make the end of the limit pin 71 engage with the limit groove 21, thereby fixing the clamp 2.

[0024] Preferably, the end of the limit pin 71 in contact with the clamp 2 is formed with a driving inclined surface 712, and the other end of the limit pin 71 extends out of the through hole 73 and is provided with a pin cap 713; the direction of the driving inclined surface 712 is as follows: Figure 2 As shown, the advantage of doing this is that when tightening the clamp 2, you only need to reduce the inner diameter of the clamp 2, the limit groove 21 will push the driving inclined surface 712 to move the limit pin 71 upward and compress the limit spring 72. When the limit pin 71 reaches the next limit groove 21, the limit spring 72 will push the limit pin 71 to engage with the limit groove 21; when you want to open the clamp 2, lift the pin cap 713 to release the limit pin 71 from the engaging state with the limit groove 21, and then open the clamp 2.

[0025] like Figure 4 、 Figure 5 As shown, a locking groove 8 is formed on the side wall of the connecting column 3 near the cam lock core 5, and the locking pin 4 can be inserted into the locking groove 8. An expansion opening 9 is formed on the outside of the locking groove 8, and the expansion opening 9 is communicated with the outside. The depth of the expansion opening 9 is less than the depth of the locking groove 8. In this embodiment, the specific shapes of the locking groove 8 and the expansion opening 9 are as follows Figure 4 、 Figure 5As shown, after the locking pin 4 is inserted into the locking groove 8, the locking tongue is rotated by a key. When the rotary tongue lock core 5 is locked, the locking tongue can limit the position of the locking pin 4, so that the locking pin 4 cannot be pulled out of the locking groove 8. It should be noted that the helmet strap should be sleeved on one end of the locking pin 4 near the expansion port 9. When the helmet strap is sleeved on the locking pin 4, the helmet strap can be stacked at the expansion port 9 and come out from the expansion port 9. Preferably, the locking pin 4 is in a "U" shape, and the locking pin 4 is rounded; the locking tongue of the rotary tongue lock core 5 is also rounded. The advantage of this is that when the locking pin 4 is not fully inserted in place, when the rotary tongue lock core 5 is closed, the locking tongue can push the locking pin 4 into the locking groove 8.

[0026] The implementation principle of the embodiment of the present utility model is as follows:

[0027] First, install the lock body 1, sleeved the clamp 2 on the handlebar, reduce the inner diameter of the clamp 2, the limit groove 21 will push the driving inclined surface 712 to move the limit pin 71 upward, and compress the limit spring 72. When the limit pin 71 reaches the next limit groove 21, the limit spring 72 will push the limit pin 71 to be clamped with the limit groove 21, thus completing the installation of the clamp 2;

[0028] Then, lock the helmet, sleeve the helmet strap on the locking pin 4, then insert the locking pin 4 into the locking groove 8, and lock the rotary tongue lock core 5 with a key. At this time, the locking tongue not only limits the position of the locking pin 4, but also limits the position of the limit pin 71. While achieving the anti-theft purpose, it can also complete the rapid disassembly and assembly of the lock body 1 when unlocking.

[0029] The above shows and describes the basic principles, main features and advantages of the present utility model.
