DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] Example:

[0029] Reference Figure 1-Figure 5 The utility model discloses a metal clip spring for an automobile guard plate assembly, comprising a first connecting rod 1 and a second connecting rod 2, wherein the first connecting rod 1 is rotatably connected to the inner side of the automobile guard plate, and the second connecting rod 2 is interference-connected to the inner side of the door sheet metal of the automobile;

[0030] Two rotating blocks 101 are arranged at one end of the first connecting rod 1 away from the automobile guard plate. The two rotating blocks 101 are symmetrically arranged according to the axis of the first connecting rod 1. A guide rod 102 is fixedly arranged at one end of the two rotating blocks 101 away from the first connecting rod 1.

[0031] Two fixed plates 201 are provided on the side of the second connecting rod 2 away from the door sheet metal, and the two fixed plates 201 are symmetrically arranged based on the axial center line of the second connecting rod 2, and a clamping plate 202 is provided at the end of the fixed plate 201 away from the second connecting rod 2, and a connecting disk 203 is slidably provided at a position between the two fixing plates 201, and a torsion spring 204 is provided on the side of the connecting disk 203, and a rotating plate 205 is provided at the end of the torsion spring 204 away from the connecting disk 203, and the rotating plate 205 is rotatably connected to the two clamping plates 202.

[0032] In this embodiment, when in use, the first connecting rod 1 is rotatably connected to the inner side of the automobile guard plate, and the second connecting rod 2 is fixedly connected to the door sheet metal of the automobile, and the first connecting rod 1 and the rotating block 101 are inserted to the position between the two clamping plates 202, and in the process of gradual insertion, the guide rod 102 will gradually touch the center of the rotating plate 205, so that the rotating plate 205 rotates. When the first connecting rod 1 and the rotating block 101 are inserted between the two clamping plates 202, the two side walls of the rotating block 101 will contact the clamping plates 20 2, the side walls of the rotating block 101 are in contact with each other, and the rotating block 2 cannot be rotated, so that one end of the torsion spring 204 can be rotated to accumulate potential energy. When the rotating block 101 is fully inserted into the position between the two clamping plates 202, the potential energy accumulated by the torsion spring 204 is released, and the first connecting rod 1 and the rotating block 101 automatically complete the rotation, so that the rotating block 101 is clamped into the interior of the clamping plate 202, thereby connecting the first connecting rod 1 and the second connecting rod 2 to each other, and then achieving the effect of fixing the automobile guard plate to the door sheet metal of the automobile.

[0033] When the automobile guard plate is installed on the door sheet metal of the automobile, the rotating blocks 101 on both sides of the first connecting rod 1 are rotated to positions corresponding to the gap between the two clamping plates 202, and the first connecting rod 1 is inserted into the gap formed by the two clamping plates 202 away from the end of the second connecting rod 2. Figure 1 and Figure 3 At this time, the two side walls of the rotating block 101 are in contact with the side walls of the clamping plate 202, so that the first connecting rod 1 cannot rotate. In the process of the first connecting rod 1 gradually approaching the second connecting rod 2, the guide rod 102 will be inserted into the rotating plate 205 and cause the rotating plate 205 to rotate, thereby twisting the torsion spring 204 through the rotation of the rotating plate 205, so that it accumulates rotational potential energy. When the two rotating blocks 101 completely correspond to the positions of the two clamping plates 202, the side walls of the clamping plate 202 and the rotating blocks 101 are in contact with each other. The side walls are not in contact, and at this time, one end of the rotating block 101 is in contact with the rotating plate 205, and the torsion spring 204 rotates, and then the rotating plate 205 connected to the torsion spring 204 also rotates, thereby driving the two rotating blocks 101 to rotate, so that the two rotating blocks 101 enter the clamping cavity 207 of the clamping plate 202, and at this time, the linear directions of the axis lines of the first connecting rod 1 and the second connecting rod 2 are fixed to each other, thereby achieving the purpose of fixing the automobile guard plate to the door sheet metal of the automobile;

[0034] Then, the rotating block 101 is rotated by twisting the clockwork spring 204 to achieve the effect of making the rotating block 101 snap into the inside of the card plate 202, thereby effectively avoiding the problem of the buckle being worn by the limit groove and easily causing damage, thereby achieving the effect of increasing the service life of the buckle. Compared with the prior art, the elasticity of the buckle body is used to achieve the method of interconnecting with the card slot, which can effectively reduce the wear between the rotating block and the card plate, and can effectively extend the service life of the retaining spring.

[0035] In a further preferred embodiment of the present invention, Figure 1-5 As shown, fixing rods 206 are slidably provided on both sides of the connecting plate 203 , and the fixing rods 206 are fixedly connected to the second connecting rod 2 .

[0036] In this embodiment, since the two ends of the torsion spring 204 are fixedly connected to the connecting disk 203 and the rotating plate 205 respectively, when the movement directions of the connecting disk 203 and the rotating plate 205 are different, the torsion spring 204 can be twisted, thereby achieving the purpose of accumulating rotational potential energy. The fixed rods 206 on both sides are used to install the connecting disk 203, so as to prevent the connecting disk 203 from rotating and consume the potential energy of the torsion spring 204, and then the rotating plate 205 can be rotated by the guide rod 102, so that the torsion spring 204 is twisted, thereby achieving the effect of accumulating rotational potential energy.

[0037] In a further preferred embodiment of the present invention, Figure 1-5As shown, the clamping plate 202 is provided with a clamping cavity 207 matched with the rotating block 101 , and a limiting plate is provided at one side of the inner side of the clamping cavity 207 .

[0038] In this embodiment, the card cavity 207 is provided to position the rotating block 101, and the limit plate is provided to position the rotating block 101 to prevent it from excessive rotation, which would cause the rotating block 101 to rotate out of the card cavity 207, so as to achieve the effect of fixing the rotating block 101 inside the card cavity 207, thereby achieving the purpose of connecting the rotating block 101 to the card plate 202.

[0039] In a further preferred embodiment of the present invention, Figure 1-5 As shown, three guide grooves 103 are formed on the outer surface of the guide rod 102 . The guide grooves 103 are arc-shaped, and one end of the guide rod 102 away from the rotating block 101 is arc-shaped.

[0040] In this embodiment, the guide groove 103 is provided to drive the rotating plate 205 to rotate when the guide rod 102 is inserted into the rotating plate 205, and then the rotation of the rotating plate 205 drives one end of the torsion spring 204 to rotate, so that the torsion spring 204 accumulates rotational potential energy.

[0041] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a positioning hole 208 is opened at the center of the rotating plate 205, and three guide blocks 209 are rotatably set on the inner wall of the positioning hole 208, and the guide blocks 209 correspond to the guide grooves 103 one by one, and the guide blocks 209 are slidably matched with the guide grooves 103, and both ends of the guide blocks 209 are arc-shaped.

[0042] In this embodiment, as the first connecting rod 1 gradually approaches the second connecting rod 2, the guide rod 102 is gradually inserted into the positioning hole 208, and the guide rod 102 end displacement arc setting makes it easy to insert the guide rod 102 into the interior of the positioning hole 208, and at this time, the guide block 209 will slide into the interior of the guide groove 103, and in the process of the guide rod 102 gradually moving, the position of the guide block 209 inside the guide groove 103 is continuously changed, so as to achieve the effect of rotating the rotating disk, and then achieve the purpose of twisting the torsion spring 204 to accumulate potential energy, and because the rotating plate 205 and the rotating block 101 are opposite to each other. The side surface is provided with a rubber plate, so that the friction between the rotating plate 205 and the rotating block 101 can be effectively increased by the rubber plate, and then the purpose of driving the rotating block 101 to rotate by the rotating plate 205 can be achieved, so as to achieve the effect of clamping the rotating block 101 into the interior of the clamping plate 202.

[0043] In a further preferred embodiment of the present invention, Figure 1-5 As shown, guide holes 2010 are provided at the axis centers of the connecting disk 203 and the second connecting rod 2 .

[0044] In this embodiment, the guide hole 2010 is provided to guide the guide rod 102 to avoid the guide rod 102 from colliding with the connecting plate 203 and causing damage to the guide rod 102, thereby achieving the purpose of protecting the guide rod 102.

[0045] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
