[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5As shown, the utility model provides a connection structure between a base and a seat back for a child safety seat, comprising a base body 1, a quick installation component 2 is arranged on the surface of the base body 1, the quick installation component 2 comprises a slide 201 and a socket 202, the slide 201 is arranged on the surface of the base body 1, the inner walls on both sides of the slide 201 are provided with sockets 202, a slider 203 is arranged inside the slide 201, a child seat 206 is fixedly connected to the top of the slider 203, two groups of notches 204 are symmetrically arranged on the front surface of the slider 203, a spring 205 is arranged inside the notch 204, and one side of the spring 205 A push block 207 is connected, an insert block 208 is connected to one side of the push block 207, a shift block 209 is connected to the front surface of the push block 207, a rubber block 210 is connected to the outer surface of one side of the shift block 209, the slider 203 has a "T" shape, the slider 203 is slidably connected to the base body 1 through the slide groove 201, the position and size of the insert block 208 match the position and size of the socket 202, the push block 207 forms an elastic structure with the spring 205 through the slot 204, the insert block 208 and the socket 202 are snap-fitted, and the outer surface of the slider 203 fits the inner surface wall of the slide groove 201.

[0025] The effect achieved by the entire embodiment 1 is that after the base body 1 is fixed, when the child seat 206 needs to be installed on the base body 1, the slider 203 at the bottom of the child seat 206 can be directly pushed into the slide groove 201. When the plug block 208 contacts the inner wall of the slide groove 201, the slider 203 is continued to be pushed so that the oblique part of the plug block 208 is squeezed by the inner wall of the slide groove 201. At this time, the plug block 208 will push the push block 207 to squeeze the spring 205, and make the plug block 208 shrink toward the notch 204. When the slider 203 is completely pushed into the slide groove 201, the position of the plug block 208 will also match the position of the socket 202. At this time, the spring 205 will use its own elasticity to push the push block 207 to drive the plug block 208 to be inserted into the socket 202 for fixation, thereby realizing the rapid installation of the child seat 206. When the child seat 206 needs to be disassembled, the two sets of shifting blocks 209 can be grasped and pushed inward at the same time, so that the shifting block 209 can drive the push block 207 to be squeezed toward the spring 205, and drive the plug block 208 to be pulled out of the socket 202. After that, the child seat 206 can be slid out of the slide groove 201 through the slider 203, completing the rapid disassembly of the child seat 206, realizing rapid installation and disassembly, and avoiding the problem that the existing child seat 206 is time-consuming, labor-intensive and inconvenient to install.

[0026] Embodiment 2, as Figure 1 , Figure 2 and Figure 6As shown, a pedal assembly 3 is provided on the front surface of the base body 1, and the pedal assembly 3 includes a bracket 301 and a threaded hole 302. Two groups of brackets 301 are respectively connected to the front surfaces of both sides of the base body 1. The internal array of the brackets 301 is provided with threaded holes 302. Two groups of side ears 303 are attached to the front surfaces of the two groups of brackets 301. A group of connecting plates 305 are fixedly connected to the bottom of the two groups of side ears 303. A threaded rod 304 is inserted into the inside of the side ear 303. The threaded rod 304 passes through the side ear 303 and forms a threaded connection with the threaded hole 302.

[0027] The effect achieved by the entire embodiment 2 is that when children of different heights sit on the child seat 206, the threaded rod 304 can be rotated in the opposite direction to remove the threaded rod 304 from the threaded hole 302 at the current height, and then the height of the connecting plate 305 is adjusted to an appropriate height, and the threaded rod 304 is passed through the side ear 303 and then threadedly connected and fixed to the threaded hole 302 at the current height. In this way, children of different heights can sit on the child seat 206, and their feet can be placed on the surface of the connecting plate 305 to rest, so as to prevent the children's legs from hanging in the air. Maintaining this posture for a long time will make the children feel tired and uncomfortable.

[0028] Working principle: When the child seat 206 needs to be installed on the base body 1, the slider 203 at the bottom of the child seat 206 can be slid and installed into the slide groove 201, and the child seat 206 can be fixed by inserting the plug block 208 into the socket 202, so as to achieve quick installation, avoiding the problem that the existing child seat 206 is time-consuming, labor-intensive and inconvenient to install. The height of the connecting plate 305 can be adjusted by the threaded rod 304, so that children of different heights can place their feet on the surface of the connecting plate 305 when sitting on the child seat 206, so as to avoid the problem that the children's legs are suspended in the air. Maintaining this posture for a long time will make the children feel tired and uncomfortable.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
