[0002] Child safety seats are generally used when children are riding in cars to improve their safety. Child safety seats typically consist of a base and a seat body mounted on the base. To prevent the child safety seat from tipping over, to make the installation more secure, and to reduce forward displacement caused by a collision, thus improving safety performance.

[0003] Child safety seats also include support legs that rest on the bottom of the base. These support legs are usually telescopic to accommodate different vehicles. When a child safety seat is installed correctly, the lower part of the support legs must rest against the car floor to function.

[0004] When installing a child safety seat, the base is first placed on the seat, and then the sliding plate precisely engages with the interface slot inside the car seat to form a rigid connection, reducing the displacement of the safety seat in a collision and improving safety. Then, the support leg is extended downwards and locked to the car floor through the buckle. However, there is a possibility of a sudden car accident while the car is in motion. Since the support leg is fixed, it cannot dissipate the inertia of the impact, and the inertial impact force can easily affect the safety of the child in the seat.

[0005] Therefore, it is necessary to provide a child car seat safety support leg to solve the above-mentioned technical problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0018] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a child car seat safety support leg provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the protective device. Figure 3 for Figure 2 The diagram shown is a bottom view of the protective device. Figure 4 for Figure 1 The enlarged schematic diagram at point A is shown.

[0019] A child car seat safety support leg includes: a support base 1; Connecting block 2, which is disposed at the bottom of the support plate 1; The seismic base 3 is disposed at the bottom of the connecting block 2. The seismic base 3 includes a base plate 31, sliding rods 32, stop blocks 33 and elastic elements 34. The base plate 31 is disposed at the bottom of the connecting block 2. The four sliding rods 32 are respectively fixedly installed around the top of the base plate 31. The stop blocks 33 are fixedly installed at the top of the sliding rods 32. The elastic elements 34 are sleeved on the bottom of the outer surface of the sliding rods 32. The protective device 5 is fixedly installed in the middle of the top of the seismic base 3. The protective device 5 includes a mounting box 51, a setting groove 52, an airbag 53, a connecting pipe 54, and a support pipe 55. The mounting box 51 is fixedly installed in the middle of the top of the base plate 31. The setting groove 52 is opened in the middle of the top of the mounting box 51. The airbag 53 is disposed at the bottom of the setting groove 52. The four connecting pipes 54 are respectively connected to the four sides of the airbag 53. The support pipe 55 is disposed at one end of the connecting pipe 54. The extrusion device 4 is fixedly installed in the middle of the bottom of the connecting block 2. The extrusion device 4 includes a connecting plate 41, a fixing plate 42, a sealing gasket 43, and a pin 44. The connecting plate 41 is fixedly installed in the middle of the bottom of the connecting block 2, the fixing plate 42 is fixedly installed at the bottom of the connecting plate 41, the sealing gasket 43 is fixedly installed on the outer periphery of the bottom of the fixing plate 42, and the pin 44 is located in the middle of the bottom of the fixing plate 42.

[0020] The connecting block 2 is slidably mounted on the top of the outer surface of the slide rod 32, and the elastic element 34 adopts a spring structure, with the top end of the elastic element 34 fixedly connected to the connecting block 2.

[0021] Both the support tube 55 and the connecting tube 54 are made of soft rubber. The top and bottom ends of the support tube 55 are fixedly connected to the connecting block 2 and the base plate 31, respectively.

[0022] A storage plate 7 is slidably mounted on the top of the outer surface of the support plate 1. A threaded hole 8 is opened on the surface of the storage plate 7, and a threaded rod 9 is engaged in the internal thread of the threaded hole 8.

[0023] The support plate 1 has multiple slots 6 evenly spaced from top to bottom on its front side.

[0024] The sealing gasket 43 is made of rubber and is attached to the perimeter of the inner wall of the setting groove 52. As the fixing plate 42 moves downward in the setting groove 52, it compresses the air in the setting groove 52.

[0025] When the airbag 53 is not punctured, the gas inside the airbag 53, connecting tube 54 and support tube 55 is not full, so the connecting tube 54 and support tube 55 do not remain in an inflated state. After the airbag 53 is punctured, as the fixing plate 42 moves downward, the gas is squeezed into the connecting tube 54 and support tube 55, causing the support tube 55 to inflate and become a vertical column to support the connecting block 2 and the base plate 31.

[0026] The working principle of the child car seat safety support leg provided by this utility model is as follows: During operation, when the impact force exceeds that of the elastic element 34, the connecting block 2 slides and compresses the elastic element 34 on the surface of the slide rod 32. The connecting block 2 drives the fixing plate 42 to move downward on the surface of the setting groove 52. The pin 44 punctures the airbag 53, and the gas inside the airbag 53 is released. As the fixing plate 42 pushes the sealing gasket 43 to move downward inside the setting groove 52, the released gas is squeezed into the interior of the support tube 55 through the connecting tube 54, causing the support tube 55 to expand and support the base plate 31 and the connecting block 2, improving the support effect of the connecting block 2 and providing shock absorption for the support leg subjected to impact force.

[0027] Compared with related technologies, the child car seat safety support leg provided by this utility model has the following beneficial effects: This utility model provides a safety support leg for a child car seat. By installing an anti-vibration base 3, a compression device 4, and a protective device 5 at the bottom of the connecting block 2, when the support leg is subjected to an impact force exceeding the shock-absorbing force of the elastic element 34, the pin 44 will puncture the airbag 53, causing the gas inside the airbag 53 to be forced into the support tube 55. This causes the support tube 55 to expand and support the base plate 31 and the connecting block 2. Together with the elastic element 34, it provides shock absorption against the impact force. This device has a simple structure, is highly practical, improves the shock absorption effect of the support leg against the inertia of a car accident, and enhances the safety of the car seat.
