AI Technical Summary
In traditional bolt installation structures, bolts are prone to falling out during the hole alignment process, resulting in low installation efficiency and making it difficult to improve stability through manual skill.
A pre-alignment mounting structure for bolts is designed. By setting a slot structure and a weak connection structure on the mounting hole, the bolt is aligned with the mounting hole after being inserted into the slot, reducing manual alignment time.
It improves the efficiency of bolt installation, reduces the overall installation time, and ensures that the alignment and adsorption time between the bolt and the bolt gun remains unchanged.

Abstract
Description
Technical Field
[0001] This utility model relates to a bolt installation structure. Background Technology
[0002] Interior trim components are typically installed to the vehicle body using clips, screws, or bolts. Traditional bolt-mounted installations only have mounting holes at the connection points. During installation, the bolt is first attached to a bolt gun and then aligned with the bolt hole. This alignment process can cause the bolt to slip off the bolt gun, slowing down the installation process. In this method, further improving installation efficiency and reducing time relies heavily on the operator's skill in drilling, making it difficult to consistently improve efficiency. Utility Model Content
[0003] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide a pre-alignment installation structure for bolts, thereby solving the problem that bolt installation structures are difficult to further improve installation efficiency.
[0004] The technical solution of this utility model is as follows: A pre-alignment installation structure for a bolt includes an installation connection part and a pre-clamping part. The installation connection part has an installation hole. The pre-clamping part includes a slot structure and a fixed connection structure. The fixed connection structure is fixedly connected to the installation connection part. The slot structure is connected to the installation connection part through a weak connection structure and is located above the installation hole. The slot structure has an opening slot opposite to the installation hole. When the bolt is inserted into the opening slot, the end of the bolt is aligned with the installation hole. The strength of the weak connection structure is less than the connection strength between the fixed connection structure and the installation connection part.
[0005] Furthermore, the weak connection structure is a V-shaped groove arranged around the opening groove.
[0006] Furthermore, the weak connection structure consists of several connection points arranged around the opening slot.
[0007] Furthermore, the opening of the slot is configured as an outwardly expanding V-shape.
[0008] Furthermore, when the bolt is inserted into the opening groove, the distance between the end of the bolt and the mounting hole is no more than 0.5mm, so as to avoid the bolt end deviating from the mounting hole when tightening the bolt and affecting the pre-alignment effect due to excessive spacing.
[0009] The advantages of this utility model compared with the prior art are as follows:
[0010] This invention uses a slot structure set above the mounting hole to ensure the alignment of the bolt with the mounting hole by snapping it into the slot, saving the time of manual alignment. The time required to snap the bolt into the slot is less than the original bolt alignment time, while the time required for the bolt to be aligned and attracted by the bolt gun remains unchanged. Therefore, the overall installation time can be reduced and the installation efficiency can be improved. Attached Figure Description

[0012] Figure 2 This is a schematic diagram of the pre-alignment mounting structure for bolts in Example 1, showing the bolt being inserted into the bolt.
[0013] Figure 3 This is a schematic diagram of the pre-alignment installation structure of the bolts in Example 2. Detailed Implementation
[0014] The present invention will be further described below with reference to the embodiments, but this is not intended to limit the present invention.
[0015] Example 1, please refer to Figure 1 As shown, the bolt pre-alignment mounting structure involved in this embodiment is mainly used for the installation of interior trim parts in vehicles, but is not limited to such products. The product body 1 has a mounting connection part 2 and a pre-locking part 3. The mounting connection part 2 has mounting holes 201 for bolts 4 to pass through, and the bolts 4 passing through the mounting holes 201 are connected to the position on the product body 1 where they are to be installed. The mounting connection part 2 and the product body can be integrally injection molded, or they can be connected by other methods.
[0016] The pre-clamping part 3 includes a slot structure 301 and a fixed connection structure 302. The pre-clamping part 3 and the product body 1 can also be integrally injection molded. In this embodiment, the fixed connection structure 302 includes fixed walls 302a located on both sides of the mounting hole 201 and a connecting plate 302b arranged parallel to the mounting connection part 2. The connecting plate 302b and the fixed walls 302a are integral structures. The connecting plate 302b is connected to the slot structure 301 through a weak connection structure. The slot structure 301 is a plate structure with an opening slot 301a. The position of the opening slot 301a corresponds to the position of the mounting hole 201. Thus, the connecting plate 302b and the slot structure 301 constitute the same plate-shaped body. A V-shaped groove 303, forming a U-shaped path around the opening groove 301a, is formed on the plate-like body. This V-shaped groove 303 is a weak connection structure. The strength of this weak connection structure is less than the connection strength between the connecting plate 302b and the fixed wall 302a, and also less than the connection strength between the fixed wall 302a and the mounting connection part 2. Overall, the strength of the weak connection structure is less than the connection strength between the fixed connection structure 302 and the mounting connection part 2.
[0017] The slot 301a on the slot structure 301 is used to engage the bolt 4. To facilitate the engagement of the bolt 4, the opening of the slot 301a is designed to be outwardly flared in a V-shape. Figure 2 As shown, when bolt 4 is inserted into the slot 301a, the distance between the end of bolt 4 and the mounting hole 201 is no more than 0.5mm. During installation, bolt 4 is inserted into the slot 301a, with the end of bolt 4 aligned with the mounting hole 201. When bolt 4 is tightened with a bolt gun, the V-groove 303 will tear under force, and the slot structure 301 will be fixed to the mounting connection 2. Since it is no longer necessary to manually align bolt 4 with the mounting hole 201 before tightening bolt 4, and the time required for bolt 4 to be inserted into the slot 301a is less than the alignment time, installation efficiency can be improved.
[0018] Example 2, please refer to Figure 3 As shown, the difference between the pre-alignment mounting structure of the bolts in this embodiment and that in Embodiment 1 lies in the specific form of the weak connection structure. In this embodiment, the weak connection structure consists of several connection points 304 connecting the connecting plate 302b and the slot structure 301, and their strength is also less than the connection strength between the fixed connection structure 302 and the mounting connection part 2. When the bolt gun tightens the bolt 4, the connection point breaks under stress, thereby fixing the slot structure 301 together with the mounting connection part 2.
