Description

Technical Field

[0001] This application relates to the field of automotive fastener technology, and in particular to an automotive metal clip with a barbed structure. Background Technology

[0002] Most existing automotive metal clips can only constrain the edges of components. For plate-shaped components, constraining only the edges can easily lead to problems such as inadequate fit and bulging in the middle. Utility Model Content

[0003] The purpose of this application is to provide a vehicle metal buckle with a barbed structure that can constrain the middle of a component.

[0004] To achieve the above objectives, this application provides a vehicle metal buckle with a barbed structure: including an elastic clip, the elastic clip having an arc-shaped piece, each of the two sides of the arc-shaped piece having a pair of curved pieces, each curved piece having a support piece at its upper end, a bridging piece between the ends of the paired support pieces, a ratchet plate fixedly connected between the side of the bridging piece and the side of the arc-shaped piece, each ratchet plate being located between two pairs of curved pieces on the same side, the ratchet plate having a plurality of diagonal braces and crossbars, the diagonal braces and crossbars being the same number and arranged at intervals to form a barbed structure.

[0005] As a preferred embodiment, the two pairs of curved plates are symmetrical, the two pairs of supporting plates are symmetrical, the two ratchet plates are symmetrical, and the entire metal buckle has a symmetrical structure.

[0006] As a preferred embodiment, the two pairs of curved pieces are parallel, and the two pairs of supporting pieces are parallel, so that not only the left and right structures are symmetrical, but also the front and back structures are symmetrical.

[0007] As a preferred embodiment, the two pairs of support plates extend in opposite directions and slope downwards in opposite directions to form a slope that facilitates finger application of force.

[0008] As a preferred embodiment, both bridging plates are flat plates in the same plane, suitable for direct contact with the surface of the constrained component.

[0009] As a preferred embodiment, the two curved pieces in pairs are located at the two ends of the arc piece, with the side edges of the curved pieces flush with the end faces of the arc piece.

[0010] As a preferred embodiment, the lower end of the ratchet plate is tangent to the arc plate, and the upper end of the ratchet plate is connected to the side of the bridging plate located between the support plates, wherein the upper end of the ratchet plate does not obstruct the contact between the bridging plate and the surface of the component.

[0011] As a preferred embodiment, a pressure plate is also fixedly connected between the two pairs of support pieces to increase the contact area between the metal buckle's force-bearing parts and the fingers.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: (1) By symmetrically setting a ratchet plate structure in the V-shaped elastic body, the spacing of the ratchet plates gradually increases from bottom to top. Not only can it easily slide into the insertion channel in the middle of the stacked components, but it is also not easy to fall off after insertion. It can effectively constrain the relative distance of each layer of components and effectively reduce the problem of inadequate fit and bulging in the middle of the stacked components. (2) By designing symmetrically unfolded support plates, the metal clips can be easily removed from the insertion channel by simply squeezing them relative to each other during disassembly. Therefore, disassembly is very convenient and beneficial for later maintenance operations. Attached Figure Description

[0021] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0022] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0023] like Figure 1-5 The illustrated metal buckle with barbed structure includes a metal elastic clip 1. The elastic clip 1 has an arc plate 101 with a minor arc cross-section. Each side of the arc plate 101 has a pair of curved plates 102. The curved plates 102 remain straight when not under stress. The lower end of the curved plates 102 is always tangent to the arc plate 101. The two pairs of curved plates 102 are located at the two ends of the arc plate 101, respectively. The side of the curved plates 102 is flush with the end face of the arc plate 101. The two pairs of curved plates 102 are symmetrical and parallel. The two pairs of curved plates 102 and the arc plate 101 form a V-shaped structure.

[0024] Each curved piece 102 has a support piece 103 at its upper end, so there are two pairs of support pieces 103. The two pairs of support pieces 103 are also symmetrical and the two pairs of support pieces 103 are parallel. The two pairs of support pieces 103 extend in opposite directions and tilt downward in opposite directions. The height of the end of the support piece 103 away from the curved piece 102 is lower than the height of the upper end of the curved piece 102.

[0025] The ends of the paired support pieces 103 are connected by bridging pieces 104, both of which are flat plates in the same plane and are lower than the upper end of the curved piece 102.

[0026] A ratchet plate 3 is fixedly connected between the side of the bridging plate 104 and the side of the arc plate 101. Each ratchet plate 3 is located between two pairs of curved plates 102 on the same side. The lower end of the ratchet plate 3 is tangent to the arc plate 101, and the upper end of the ratchet plate 3 is connected to the side of the bridging plate 104 located between the support plates 103. Similarly, the two ratchet plates 3 are symmetrical to each other, so that the entire automotive metal has a symmetrical structure.

[0027] The ratchet plate 3 has several diagonal braces 301 and cross plates 302. The diagonal braces 301 are necessarily inclined relative to the bridging plate 104, and the angle between the diagonal braces 301 and the bending plate 102 in the unloaded state is an acute angle. The cross plates 302 are approximately parallel to the bridging plate 104. The number of diagonal braces 301 and cross plates 302 are the same and they are arranged at intervals. That is to say, both sides of the cross plates 302 are connected to the diagonal braces 301. Except for the diagonal braces 301 located at the top and bottom, the upper and lower sides of the remaining diagonal braces 301 are connected to the cross plates 302.

[0028] A pressure plate 2 is fixedly connected between the two pairs of support plates 103. The pressure plate 2 is parallel to the two connected support plates 103 and the two pressure plates 2 are also symmetrical, which is used to increase the contact area between the metal buckle and the finger.

[0029] Working principle: This automotive metal clip is suitable for clamping at least two stacked parts together. These stacked parts have a connected insertion channel. During installation, the arc plate 101 is pointed towards the insertion channel, and the metal clip is pressed down. The symmetrical ratchet plates 3, due to their small lower end spacing and large upper end spacing, slide down and adhere closely to the inner wall of the insertion channel, gradually approaching until they penetrate all the stacked parts. At the same time, the two bridging plates 104 contact the surface of the first inserted part. Due to the outward expansion elasticity of the bending plate 102, the inclined support plate 301 of the ratchet plate 3, together with the cross plate 302, will prevent the metal clip from disengaging from the insertion channel, thereby maintaining the stable configuration of the metal clip. When it is necessary to disassemble the metal clip, apply relative squeezing force to the two symmetrical pressure plates 2 with your thumb and forefinger, forcing the two pairs of bridging plates 104 to move closer to each other, thereby reducing the gap between the upper ends of the two ratchet plates 3. The cross plate 302 disengages from the inner wall of the insertion channel, and the diagonal brace 301 no longer provides support for the cross plate 302. The part of the metal clip inserted into the insertion channel can be easily disengaged, and the stacked parts constrained by the metal clip can be easily separated.
