Detailed Description

The utility model provides a possess the locking and press the T type bolt on edge. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.

The T-shaped bolt with the locking pressing edge comprises a bolt head 1 and a screw rod 2, a limiting platform 3 with a square cross section is arranged between the bolt head 1 and the screw rod 2, the bolt head 1 is provided with two extending piles 4 extending along the radial direction of the screw rod 2, a concave groove 5 perpendicular to the extending direction of the extending pile 4 is arranged at the bottom of any extending pile 4, one end of the concave groove 5 is connected with the limiting platform 3, and a pressing edge 6 is formed between the other end of the concave groove and the extending end of the extending pile 4.

The specific implementation process and principle description are as follows:

as shown in figure 3, firstly, the T-shaped bolt is slidably matched to a preset position along the direction of an aluminum profile groove, at the moment, due to the relative sliding fit between the limiting table 3 with the positive and negative cross sections and the strip groove, the axial position degree of the T-shaped bolt can be ensured, then, the bolt nut is locked by the threaded fit of the bolt nut and the screw rod 2, in the locking process, the bolt head 1 has an axial compression joint stroke, due to the design of the concave groove 5, the compression joint edge 6 has certain compression joint deformation, meanwhile, the compression joint edge 6 has a smaller contact area, and can be partially embedded into the bottom wall of the profile groove to realize stable matching, so that the looseness is effectively prevented.

In one embodiment, as shown in fig. 4, a wedge-shaped extension 7 is formed between the concave groove 5 and the stopping table 3.

In the screwing and locking process of the bolt nut, the wedge-shaped extension edge 7 can be tightly matched with the aluminum profile groove, so that the locking between the bolt head 1 and the groove is firmer and more stable.

In a particular embodiment, as shown in fig. 1 and 2, the bottom of the crimping rim 6 is provided with a slot 8 in the same direction as the extension of the extension post 4.

The grooving 8 can ensure that the compression joint edge 6 and the support surface of the groove are matched more stably and reliably, basically eliminates the possibility of sliding of the T-shaped bolt, and ensures that the locking is more stable.

In one embodiment, four end corners of the limiting table 3 are respectively provided with an avoiding chamfer 9. The avoiding chamfer 9 can meet the requirement of smooth slide assembly.

This spacing platform 3 is the preferred spacing platform of cold-heading shaping, can reduce the material quantity through the fashioned mode of cold-heading, reduction in production cost.

In one embodiment, the outer surface of the T-bolt is provided with an anti-corrosion coating. The T-shaped bolt is made of stainless steel, and the surface of the T-shaped bolt is also provided with an anti-corrosion coating, so that the service life of the T-shaped bolt can be prolonged.

Can discover through the above description, the utility model discloses possess the T type bolt that the lock pressed the edge admittedly, through the crimping along with the cooperation design of spacing platform, can improve the lock solid position accuracy and the lock solid stability of T type bolt, prevent effectively that not hard up from appearing in T type bolt, satisfy the lock solid application demand. The design of wedge-shaped extending edges and the grooves is provided, the matching stability of the T-shaped bolt is further improved, the T-shaped bolt is effectively prevented from sliding towards the grooves, and the locking effect is maintained for a long time. The whole design is simple and ingenious, the manufacture is easy, and the method is suitable for popularization and application.

The above technical solutions of the present invention have been fully described, and it should be noted that the present invention is not limited by the above description, and all technical solutions formed by equivalent transformation or equivalent transformation adopted by the spirit of the present invention in the aspects of structure, method or function by those of ordinary skill in the art all fall within the protection scope of the present invention.
