detailed description

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of the present invention.

Example 1

As shown in Figure 1, this embodiment proposes a safety belt for pregnant women, in particular a self-installing buckle for pregnant women, including a connecting buckle A10 and a connecting buckle used in conjunction with the connecting buckle A10 to connect the safety belt B20 and the auxiliary connecting belt 101 for preliminarily fixing the connecting buckle A10 and the connecting buckle B20.

In this embodiment: the worker connects the safety belt to the connection buckle A10 and the connection buckle B20, and then engages the connection buckle A10 and the connection buckle B20 to fix the safety belt. When it is connected, the connection buckle A10 and the connection buckle B20 An auxiliary connecting belt 101 is also provided on the upper part, and the auxiliary connecting belt 101 is preliminarily fixed to the connecting buckle A10 and the connecting buckle B20 by means of sewing.

It should be noted that the dotted line structure on the connecting buckle B20 is the internal structure of the connecting buckle B20.

More specifically: as shown in Figures 2, 3 and 4, the connecting buckle A10 includes a connecting piece 14 integrally formed on the right side of the connecting buckle A10, and a connecting plate A12 on the upper surface of the connecting buckle A10 fixed by bolts and openings on the The connecting hole A11 on the surface of the connecting buckle A10 is used to connect the safety belt. The right side of the connecting plate A12 is integrally formed with a protrusion 15 and the right side of the connecting piece 14 is provided with a notch A13.

It should be noted that the above-mentioned components are made of stainless steel, and the structure of the spring 26 and the buckle 23 are not shown in FIG. 3.

The connecting buckle B20 includes a connecting hole B21 opened on the surface of the connecting buckle B20 for connecting the seat belt, a connecting plate B22 integrally formed on the left side of the connecting buckle B20, and a gap B25 opened on the left side of the connecting plate B22, and the surface of the connecting plate B22 Three connecting rods 24 are provided, and the three connecting rods 24 pass through the surface of the connecting plate B22. Two of the connecting rods 24 are symmetrically distributed along the horizontal line of the connecting plate B22, and are connected to the buckle 23 located inside the connecting plate B22. A spring 26 is also arranged inside the board B22. The two buckles 23 and the inner wall of the connecting board B22 are fixedly connected by the spring 26, and one connecting rod 24 is located on the horizontal line of the connecting board B22.

It should be noted that the connecting plate B22 is a hollow structure. The outer side wall of the connecting piece 14 is provided with two grooves, and the two grooves are symmetrically distributed along the horizontal line of the connecting piece 14. When the connecting buckle A10 and the connecting buckle B20 are connected, the buckle 23 is engaged with the groove of the connecting piece 14 Place.

In this embodiment: the above-mentioned parts are made of stainless steel. In combination with the above content, when the connecting buckle A10 and the connecting buckle B20 are connected, the connecting piece 14 is accommodated in the connecting plate B22, because the outer side wall of the buckle 23 and the connecting plate B22 pass through the spring 26 is fixedly connected, and then the buckle 23 is resisted by the spring 26, and the buckle 23 is further locked to the connecting piece 14. The gap A13 and the outer side wall of the connecting rod 24 on the horizontal line of the connecting plate B22 leave a certain distance (the distance 0.5 cm), and the protrusion 15 and the notch B25 fit.

It should be noted that: as an improved technical solution of the present invention, the buckle 23 has a Z-shaped structure, and the surface of the buckle 23 is provided with a through hole, the connecting rod 24 penetrates the through hole, and the buckle 23 and the connecting plate B22 The connecting rod 24 rotates and connects.

To sum up: the worker wraps the safety belt around the connecting hole A11 of the connecting buckle A10 and the connecting hole B21 of the connecting buckle B20. When the connecting buckle A10 and the connecting buckle B20 are connected, the connecting piece 14 is housed in the connecting plate B22. The outer side wall of the buckle 23 and the connecting plate B22 are fixedly connected by a spring 26, and then the spring 26 abuts the buckle 23, so that the buckle 23 is locked to the connecting piece 14. The gap A13 and the connecting rod on the horizontal line of the connecting plate B22 A certain distance is left on the outer side wall of 24, and the protrusion 15 is attached to the notch B25. When the connecting buckle A10 and the connecting buckle B20 are removed, press the buckle 23. At this time, the spring 26 is compressed, and the notch A13 and the connecting plate B22 The outer side walls of the connecting rod 24 on the horizontal line are in contact with each other, and the buckle 23 is separated from the groove on the connecting member 14, thereby disassembling the connecting buckle A10 and the connecting buckle B20.

As shown in Figure 5; as an optional technical solution of the present invention: the connection buckle A10 also includes a cobra buckle 19 integrally formed on the left side of the connection buckle A10 and two edge connection buckles A10 integrally formed on the surface of the connection buckle A10 The limit plate 17 is symmetrically distributed on the center line. The limit plate 17 is provided with a sliding rod 16 inside. The limit plate 17 and the sliding rod 16 are slidably connected. When the sliding rod 16 slides, it is formed on the limit plate 17 for winding safety Belt placement area 18.

In this embodiment: because the limit plate 17 is provided with a placement area 18, when the staff moves the sliding rod 16, the sliding rod 16 divides the interval on the placement area 18, and the staff wraps the seat belt around the limit plate 17, which is safe The belt is squeezed, thereby fixing the safety belt to the sliding rod 16.

The connecting buckle A10 is also provided with a cover plate 30 which is snapped onto the outer surface of the connecting buckle A10 and is detachably connected to the connecting buckle A10.

It should be noted that the worker can clamp the cover plate 30 on the connection buckle A10, and then seal the connection buckle A10.

This design can be used when pregnant women ride in a car (the existing products have a seat belt on the abdomen of pregnant women, and the seat belt on the abdomen will cause harm to the fetus), choose to install a seat belt and place the seat belt along the bicycle seat The longitudinal section is placed, and then the seat belt is fixed to the bicycle seat (combined with the above content "because the limit plate 17 is provided with a placement area 18, when the staff moves the sliding rod 16, the sliding rod 16 is opposed to the placement area 18 The section is divided, the staff wraps the seat belt around the limit plate 17, and the seat belt is squeezed, and then the seat belt is fixed to the sliding rod 16"), and then the seat belt on the pregnant woman’s abdomen is placed on the surface of the auxiliary connecting belt 101 When the connecting buckle A10 and the connecting buckle B20 are connected, the safety belt located on the pregnant woman’s abdomen is fixed, so that the force on the pregnant woman’s abdomen is changed from the force on the pregnant woman’s abdomen by the existing safety belt to the leg.
