Description

Technical Field

[0001] The utility model relates to the technical field of roller skating protective gear, in particular to a protective gear for children's roller skating. Background Technique

[0002] Roller skating has strong entertainment value. It is very interesting both in terms of speed and skills, and can be practiced individually or in group games, so it is very popular among children. When children use roller skates, they need to use protective gear to protect their knees. Existing protective gear for children's roller skating still has the following problems during use:

[0003] Firstly, existing roller skating protective gear is not convenient to adjust the protection area according to the knee sizes of different children during use, which reduces the adaptability of the protective gear and causes inconvenience in using the protective gear.

[0004] Secondly, for existing roller skating protective gear, the outer shell of the protective gear usually uses hard plastic as the main material. During use, it lacks an effective buffer structure. When falling down at high speed, the outer shell directly contacts the ground, which easily causes knee injuries. For this reason, we propose a protective gear for children's roller skating. Content of the Utility Model

[0028] Embodiment 3: A protective gear for children's roller skating. On the basis of Embodiment 2, as Figure 1 - Figure 4 shown in the figure, the buffer assembly 9 includes an elastic seat 19. The elastic seat 19 is an elastic hollow shell. Multiple opening grooves 20 are arranged along the axial direction on the outer arc surface of the elastic seat 19. A buffer seat 21 is arranged inside the elastic seat 19. The buffer seat 21 is a soft rubber block. The buffer seat 21 is installed at the upper end of the elastic seat 19. The lower end of the buffer seat 21 extends into the elastic seat 19. A telescopic spring 22 is arranged at the lower end of the buffer seat 21. The upper end of the telescopic spring 22 is fixedly connected to the buffer seat 21, and the lower end of the telescopic spring 22 is fixedly connected to the elastic seat 19.

The lower end of the wear-resistant pad 23 is fixedly bonded to the buffer seat 21.

[0029] It should be noted that the present utility model is a protective gear for children's roller skating. When in use, first rotate the positioning rod 15 to take out the limiting strip 16 from the inside of the mounting hole 18, and then, according to the size of the knee, pull the first protective shell 1 and the second protective shell 2 to adjust the protective area. The first protective shell 1 and the second protective shell 2 drive the moving block 11 to move along the guide rail 10 during movement. When the second limiting groove 17 at the upper end of the moving block 11 moves to the appropriate position of the first limiting groove 14, install the lower end of the positioning rod 15 inside the mounting hole 18. With the installation of the positioning rod 15, the lower end of the limiting strip 16 is inserted into the first limiting groove 14 and the second limiting groove 17 to limit the guide rail 10 and the moving block 11, thereby positioning the first protective shell 1 and the second protective shell 2. Then open the connecting buckle 7 and fasten the protective gear to the upper end of the knee. When falling during use, the buffer seat 21 will be impacted to drive the telescopic spring 22 to contract, buffering the first protective shell 1 and the second protective shell 2, thereby reducing the impact force received by the first protective shell 1 and the second protective shell 2 and not causing a huge impact on the knee, avoiding knee injury. By setting the adjusting mechanism 8, during use, according to the sizes of different children's knees, the protective area of the protective gear can be adjusted, improving the adaptability of the protective gear and making the protective gear more convenient during daily use. By setting the buffer assembly 9, the first protective shell 1 and the second protective shell 2 can be protected. When falling, the first protective shell 1 and the second protective shell 2 are buffered, thereby reducing the impact force received by the first protective shell 1 and the second protective shell 2, improving the protection effect, and avoiding knee injury.
