[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Children's products, such as strollers, car seats, high chairs, and table chairs, all include child seating devices, which are usually equipped with safety restraint systems.

[0027] The safety restraint system includes a safety buckle consisting of a plug 2 and a socket 1, a plug safety belt installed on the plug 2, and a socket safety belt installed on the socket 1.

[0028] The detailed structure of the safety buckle is as follows: As shown in the attached drawings, the safety buckle includes a socket 1, two plugs 2 that are inserted into the socket 1, a locking mechanism set inside the socket 1 to lock the plugs 2, and an unlocking component 4 set on the socket 1 to control the unlocking of the plugs 2.

[0029] In this embodiment, as Figure 2 As shown, the plug 2 has two parts, left and right. Each side of the plug 2 has a shoulder strap hole 2a and a waist belt hole 2b, one above the other. One plug can connect the shoulder strap and waist belt on the same side, which can realize the safe and stable binding function of the five-point safety buckle, and also has the advantages of the simple structure and convenient operation of the three-point buckle.

[0030] In this embodiment, the two plugs 2 correspond to the two sockets 12 arranged on the left and right sides of the socket 1. Each plug 2 has a block-shaped locking tooth that matches the shape of the corresponding socket 12 and can be inserted in the left and right direction.

[0031] The locking mechanism includes a locking member 3 that can slide between the front and back sides of the socket 1 to engage with the locking teeth for locking or unlocking, and a locking elastic member 5 disposed between the locking member 3 and the socket 1 to ensure stable engagement between the locking teeth and the locking member 3.

[0032] Among them, such as Figure 1 and Figure 3 As shown, in this embodiment, the specific structure of the locking tooth is as follows: the locking tooth includes a tooth base plate 21, a tooth middle block 22 protruding from the middle of the tooth base plate 21 in the opposite direction, and two side tooth buckles 23 protruding from the upper and lower sides of the tooth base plate 21 in the opposite direction. The tooth middle block 22 is located between the upper and lower side tooth buckles 23, and the thickness between the tooth middle block 22 and the tooth base plate 21 is greater than the thickness between the side tooth buckles 23 and the tooth base plate 21. Figure 1 As shown and Figure 3As shown, the inner surface of the back of the socket 1 has guide ramps 11 on the left and right sides respectively facing the corresponding socket 12. The guide ramps 11 have slope abutting surfaces 11a. The two locking hooks 32 on the left or right side of the locking member 3 are located on the upper and lower sides of the corresponding guide ramps 11 respectively. When the locking mechanism is locked, the lower surface of the toothed block 22 abuts against the slope abutting surface 11a on the corresponding side, making the fit tighter and effectively preventing the plug 2 from shaking inside the socket 1 after being inserted into it, thus ensuring the safety of the buckle.

[0033] The locking teeth are larger than the locking hooks on the market, and the corresponding insertion holes are also larger, making it very easy for the locking teeth to find the corresponding insertion holes and insert. In particular, the shape of the middle tooth block 22, in conjunction with the guide ramp 11, not only makes insertion easier, but also serves as an insertion guide and a stable match with the shape inside the socket 1.

[0034] like Figure 1 As shown, the locking component 3 includes a locking base plate 31 that is slidably disposed on the inner guide post of the socket 1 through a guide hole along the front and back directions, and four locking hooks 32 that are respectively hooked out in the front direction based on the upper and lower sides of the left and right sides of the locking base plate 31. Locking elastic components 5 are respectively provided between the upper and lower sides of the locking component 3 and the socket 1, so that when the locking mechanism is locked, the four locking hooks 32 on the left and right sides of the locking component 3 are engaged with the two side teeth 23 of the left and right side plugs 2, and the four locking hooks 32 on the upper, lower, left and right sides are engaged and secured.

[0035] like Figure 1 As shown, the unlocking component 4 is slidably disposed in the socket 1 along a straight up-down direction. The unlocking component 4 includes two unlocking drive rods 41 located on the left and right sides of the guide post inside the socket 1, and a button 42 integrally formed and fixed to the upper part of the two unlocking drive rods 41 and extending out of the socket 1. There is an unlocking component elastic component 43 between the unlocking component 4 and the socket 1, which enables the unlocking component 4 to move upward and stabilize in the locked position.

[0036] Each unlocking drive lever 41 has a lower protrusion 41a and an upper protrusion 41b protruding in the opposite direction, and the locking member 3 has an upper unlocking guide block 3a and a lower unlocking guide block 3b protruding in the front direction and cooperating with the upper and lower protrusions.

[0037] The working process of this embodiment is described in detail below: When the locking mechanism is unlocked, the elastic force of the locking elastic element 5 and the unlocking elastic element 43 is overcome, and the button 42 is pressed down. The button 42 pushes the lower protrusion 41a and the upper protrusion 41b on the unlocking drive rod 41 to move downward until the upper protrusion 41b presses on the upper unlocking guide block 3a and the lower protrusion 41a presses on the lower unlocking guide block 3b, thereby moving the locking element 3 to the opposite side of the socket 1, so that the side tooth buckle 23 of the plug 2 disengages from the locking hook 32 of the locking element 3 to achieve unlocking. Then the plugs 2 on both sides can be pulled out, and the button 42 is released. Under the action of the elastic force of the locking elastic element 5 and the unlocking elastic element 43, the locking element 3 and the unlocking element 4 are both reset.

[0038] When it is necessary to insert the two plugs 2 into the socket 1, insert the plugs 2 on both sides into the corresponding sockets 12 respectively. The side teeth 23 of each plug 2 and the slope surface of the corresponding side locking hook 32 abut against each other, causing the locking member 3 to overcome the locking elastic member 5 and move in the opposite direction to avoid it. The plug 2 is inserted into place. At this time, the lower surface of the tooth block 22 presses against the slope pressing surface 11a on the corresponding side. The locking hook 32 of the locking member 3 hooks with the side teeth 23 of the plug 2 to achieve locking.
