Specific implementation
[0023] The technical scheme of the utility model will be described below in clear and complete manner in combination with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, instead of all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0024] Referring to Figures 1 to 5 , the utility model provides a kind of technical scheme: a kind of anti-dropping safety buckle, including middle plate 1 and T type plug 8, the two sides of middle plate 1 are connected with clamping plate 14 respectively, and middle plate 1 in reality is fixed between clamping plate 14 by riveting mode.
[0025] Middle plate 1 bottom is equipped with installation mouth 15, and arc elastic plate 16 is equipped in the top of installation mouth 15, limiting groove 12 is equipped in the two sides of the top of installation mouth 15 respectively, when installing, let the two ends of arc elastic plate 16 be respectively movably placed in limiting groove 12, and let the end of arc elastic plate 16 and the bottom of limiting groove 12 be equipped with movable spacing, so that arc elastic plate 16 can have enough deformation space;
[0026] As Figure 2 shown, T type plug 8 top is movably inserted in the middle of installation mouth 15, when T type plug 8 is placed in installation mouth 15, T type plug 8 top and arc elastic plate 16 are elastically contacted, that is, arc elastic plate 16 always exists the elastic potential energy of pushing T type plug 8 from installation mouth 15, and then as Figure 2As shown, when the T-shaped plug 8 is inserted into the installation port 15, and the bottom of the T-shaped plug 8 is located outside the installation port 15, in order to fix the T-shaped plug 8 in the installation port 15, the T-shaped plug 8 and the bottom of the installation port 15 are connected by the buckling mechanism, and the T-shaped plug 8 is in close contact with the buckling mechanism under the driving of the arc-shaped elastic plate 16. The arc-shaped elastic plate 16 firmly presses the T-shaped plug 8 on the buckling mechanism, avoiding any gap between them, thereby preventing the T-shaped plug 8 from shaking with the buckling mechanism.
[0027] The buckling mechanism will be described in detail below, as shown in Figure 2 and Figure 3 The buckling mechanism includes buttons 5 arranged on both sides of the bottom of the middle plate 1 and movable grooves 10 arranged on both sides of the top of the T-shaped plug 8. One end of the button 5 close to the T-shaped plug 8 is rotatably connected to the clamping plate 14, and the other end of the button 5 away from the T-shaped plug 8 extends to the outside of the middle plate 1 (as shown in Figure 1 and Figure 4 The end of the button 5 close to the T-shaped plug 8 is inclined upward and provided with an abutment 7, which forms a "V" structure with the button 5, and the included angle between the abutment 7 and the button 5 is obtuse. The abutment 7 is used to cooperate with the movable groove 10 to prevent the T-shaped plug 8 from being ejected by the arc-shaped elastic plate 16, as shown in Figure 2 and Figure 5 Specifically, the end of the abutment 7 is arranged on the top of the T-shaped plug 8, so that the abutment 7 abuts against the top of the movable groove 10 to prevent the T-shaped plug 8 from falling out of the installation port 15. However, in order to further improve the stability between the T-shaped plug 8 and the movable groove 10, a clamping block 3 is arranged on the top of each movable groove 10, and a clamping groove 6 corresponding to the clamping block 3 is arranged on the top of each abutment 7. The clamping block 3 is arranged in the clamping groove 6, so that the top of the movable groove 10 and the abutment 7 form a clamping structure, which can improve the stability of the abutment 7 abutting against the top of the T-shaped plug 8.
[0028] It should be emphasized that the abutment 7 in the present application has a certain elasticity, so that the abutment 7 always has a tendency to move towards the T-shaped plug 8, as shown in Figure 2 and Figure 4 The side of the abutment 7 away from the T-shaped plug 8 is connected to the side wall of the installation port 15 by an elastic mechanism, and the elastic mechanism includes a spring 17 located between the abutment 7 and the side wall of the installation port 15. Spring grooves 4 are arranged on the opposite sides of the abutment 7 and the installation port 15, and the two ends of the spring 17 are arranged in the spring grooves 4, so that the two ends of the spring 17 are fixed by the spring grooves 4 to prevent the two ends of the spring 17 from deviating or falling off.
[0029] Because the spring 17 always abuts against the abutment 7, and the abutment 7 and the button 5 are an integral structure, the abutment 7 has a tendency to drive the button 5 to rotate, as shown in Figure 2As shown, the buttons 5 are in contact with the two sides of the bottom of the middle plate 1, and the elastic mechanism supports the buttons 5 on one side of the bottom of the middle plate 1, and the two sides of the bottom of the middle plate 1 limit the buttons 5, so that the buttons 5 always stay in the preset position.
[0030] Further, the first connecting part includes a strip-shaped opening 9 arranged at the bottom of the T-shaped plug 8, which is used for connecting with the safety belt, and the second connecting part includes a first rectangular opening 2 arranged at the top of the middle plate 1, and the top of the clamping plate 14 is provided with a second rectangular opening 11 corresponding to the first rectangular opening 2, and when the clamping plate 14 is connected with the middle plate 1, the second rectangular opening 11 and the first rectangular opening 2 are overlapped, and the second rectangular opening 11 and the first rectangular opening 2 are also used for connecting with the safety belt. The two ends of the first rectangular opening 2 are in a stepped structure with the two ends of the second rectangular opening 11, so that a groove is formed between the two ends of the first rectangular opening 2 and the second rectangular opening 11, or in other words, the length of the first rectangular opening 2 is less than the length of the second rectangular opening 11, and when the clamping plate 14 is connected with the middle plate 1, a groove is formed between the two ends of the first rectangular opening 2 and the second rectangular opening 11 due to the length difference, and since the support shaft 13 is arranged in the first rectangular opening 2, in fact, the two ends of the support shaft 13 are provided with stepped shafts, and during installation, the two ends of the support shaft 13 are movably arranged in the groove, so that the two ends of the support shaft 13 can move in the groove, and the support shaft 13 is used for connecting with the safety belt.
[0031] Based on the above embodiment, the anti-disengagement safety buckle works as follows: the top of the T-shaped plug 8 is inserted into the mounting opening 15 from between the buttons 5, and the two abutments 7 are arranged obliquely upward, so the distance between the two abutments 7 is less than the width of the top of the T-shaped plug 8, and when the T-shaped plug 8 is inserted, the T-shaped plug 8 needs to push the two abutments 7 apart to the two sides;
[0032] As the T-shaped plug 8 gradually advances into the mounting opening 15, when the abutments 7 move to the movable grooves 10 along the two sides of the T-shaped plug 8, the abutments 7 are pressed into the movable grooves 10 instantaneously under the drive of the elastic mechanism, and then the clamping blocks 3 are pressed and combined with the clamping grooves 6, and at the same time, the top of the T-shaped plug 8 is in elastic contact with the arc-shaped elastic plate 16, so that the arc-shaped elastic plate 16 pushes the T-shaped plug 8 to move outward, but the T-shaped plug 8 is limited by the abutments 7, so the arc-shaped elastic plate 16 tightly presses the T-shaped plug 8 on the abutments 7 to fix it;
[0033] When it is needed to disengage the anti-disengagement safety buckle, only the T-shaped plug 8 is pushed into the mounting opening 15, the top of the abutment 7 is slid to the middle of the movable groove 10, and the top of the movable groove 10 is separated from the top of the abutment 7, and then the two buttons 5 are moved like Figure 4 this, the two abutments 7 are driven to open, and then the T-shaped plug 8 can be pulled out. If the buttons 5 are loosened, the abutments 7 and the buttons 5 are automatically returned under the drive of the spring 17, and at this time, the buttons 5 are like Figure 2 Figure 5The same is located in the middle plate 1 two sides of the bottom to achieve a stable state.
[0034] Based on the above examples, it needs to be further explained that the above has been described that the intermediate plate 1 and the clamping plate 14 are fixed by riveting, in fact, the intermediate plate 1 is clamped between the two clamping plates 14, and a plurality of riveting holes are arranged at the edge positions of the intermediate plate 1 and the clamping plate 14 respectively, and the riveting holes are just located on the end of the button 5. Therefore, when the rivets are placed in the respective riveting holes, the rivets located at the button 5 can serve as the shaft of the button 5 rotation, and then the two ends of the rivet are riveted and fixed by the riveting machine.
[0035] Based on the above examples, it needs to be further explained that the first rectangular port 2 and the mounting port 15 can be communicated or not communicated, and when the intermediate plate 1 and the two clamping plates 14 are connected, the clamping plate 14 seals the space in the intermediate plate 1, so as to seal the arc-shaped elastic plate 16, the spring 17 and other structures, and the thickness of the T-shaped plug 8 is matched with the spacing between the two clamping plates 14.
[0036] The above only describes the preferred embodiments of the present application, and does not limit the present application, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
