Technical Field

The invention relates to the technical field of automobile parts, in particular to a clamping structure and an installation structure thereof.

Background

The clamping structure is a general mode for assembling and fixing the automotive interior trim part, the clamping force and the pulling force of the clamping structure are defined according to the functional requirements of a product, in the existing structure, the pulling force of the clamping structure is provided by the elastic strength and the angle of a metal clip, the pulling force generated by elastic deformation is provided, and the defect that the clamping structure is easy to separate from the product in the using process is easily caused under special conditions, such as the condition that the inertia of the product is large. Meanwhile, under certain conditions, the pull-out force provided by the strength of the clamping structure cannot meet the pull-out force required by the functions of the parts.

Disclosure of Invention

The present invention is directed to provide an engaging structure and an installation structure thereof, which can avoid the situation of coming off during the use process and provide an extra pull-out force.

In order to achieve the purpose, the clamping structure comprises an upper body framework rib position vertically arranged on a bottom plate, wherein a metal clamp covers the upper body framework rib position, the metal clamp is U-shaped, two ends of the metal clamp extend outwards and in a direction close to the central axis of the metal clamp to form a leaning position, the end part of the leaning position continues to extend outwards and in a direction far away from the central axis of the metal clamp to form a limiting position, a limiting rib is arranged on the leaning position of the upper body framework rib position, the leaning position leans against the limiting rib, a plurality of barb columns are arranged on the inner wall of the metal clamp, the end parts of the barb columns are inserted into the upper body framework rib position, and the pointing direction of the end parts of the barb columns faces to the U-shaped bottom of the metal clamp.

Preferably, the U-shaped opening of the metal clip is gradually enlarged outwards.

Preferably, the limiting position is perpendicular to the abutting position.

Preferably, the contact part of the limiting position and the limiting rib is positioned in parallel with the limiting rib.

The utility model provides a mounting structure of joint structure is equipped with the joint interface on the joint device, pass through by the joint device the joint interface is detained on the metal clip, the U-shaped bottom of metal clip passes the joint interface, the joint interface supports to lean on the position.

Compared with the prior art, the invention has the following advantages:

1. the condition of separation in the using process can be avoided;

2. can provide additional pullout force;

3. can meet the requirements of product function quality, and is more durable and higher in reliability.

Drawings

Fig. 1 is a schematic structural view of a clamping structure according to the present invention.

The components in the figures are numbered as follows:

bottom plate 1, upper part of the body skeleton muscle position 2, metal checkpost 3, support to lean on position 4, restriction position 5, spacing muscle 6, barb post 7, by piecing devices 8, joint interface 9.

Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

As shown in figure 1, the clamping structure comprises an upper body framework rib position 2 vertically arranged on a bottom plate 1, a metal clamp 3 covers the upper body framework rib position 2, the metal clamp 3 is U-shaped, two ends of the metal clamp 3 extend outwards and in a direction close to the central axis of the metal clamp 3 to form a leaning position 4, the end part of the leaning position 4 continues to extend outwards and in a direction away from the central axis of the metal clamp 3 to form a limiting position 5, a limiting rib 6 is arranged at the position, located at the leaning position 4, of the upper body framework rib position 2, the leaning position 4 leans against the limiting rib 6, a plurality of barb columns 7 are arranged on the inner wall of the metal clamp 3, the end parts of the barb columns 7 are inserted into the upper body framework rib position 2, and the pointing directions of the end parts of the barb columns 7 face towards the U-shaped bottom of the metal clamp 3.

In this embodiment, the U-shaped opening of the metal clip 3 is gradually enlarged outward, which can better limit the position. In addition, the limiting position 5 is perpendicular to the abutting position 4, and the contact part of the limiting position 5 and the limiting rib 6 is positioned in parallel with the limiting rib 6.

When this embodiment joint structure used, its mounting structure is as shown in fig. 1, is equipped with joint interface 9 on being equipped with by joint device 8, detains on metal clip 3 through joint interface 9 by joint device 8, and joint interface 9 is passed to metal clip 3's U-shaped bottom, and joint interface 9 supports to leaning on position 4.

At this moment, the limiting rib 6 abuts against the abutting position 4 and is abutted against by the abutting position of the clamping device 8, so that the metal clip 3 is prevented from deforming, and the metal clip is accidentally dropped off by the clamping device 8. Simultaneously, when will separating by latch device 8 messenger, through spacing of spacing muscle 6, make metal clip 3 more difficult to take place deformation, can provide extra extraction power.

The clamping structure and the mounting structure thereof can avoid the situation of separation in the use process; additional pullout force can also be provided; meanwhile, the requirements on the functional quality of the product can be met, and the device is more durable and higher in reliability.
