Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to an assembly structure of a fastener. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening and connection and are extremely widely used. Fasteners are widely used in industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc. In various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters and supplies, when two assembly parts are assembled together, they are usually assembled and fixed with bolts. However, during the assembly process of traditional bolts, when the two assembly parts are about to fit tightly, the bolts are tightened again, and the two assembly parts are screwed into each other. The two assembly parts are likely to slip relative to each other, generating false axial force. The assembly parts cannot fit well and tightly, resulting in poor stability and slow assembly speed. For this reason, we propose an assembly structure for fasteners. Utility Model Content

The sliding rod is slidably connected to the inside of the supporting tube. The lower end of the sliding rod is provided with a top connection section. The outer arc surface of the top connection section is slidably connected to the lower side of the inner arc surface of the supporting tube. The lower end of the top connection section is provided with a threaded column. A tightening cap is placed at the lower end of the base. The upper end of the tightening cap is provided with an avoidance opening. The bottom wall of the avoidance opening is provided with a threaded opening. The upper end of the sliding rod is provided with a mounting seat. The structure of the fastener has strong stability and fast assembly speed.

[0007] Furthermore, the fastening mechanism also includes a guide groove, a limit rod, a spring and a slider. The guide grooves are symmetrically opened on the inner arc surface of the support tube front and back. Limit rods are provided inside the two guide grooves. Sliders are slidably connected inside the two guide grooves. The middle parts of the two sliders are slidably connected to the outer arc surface of the limit rod located in the same guide groove. Springs are provided between the lower ends of the two sliders and the bottom wall of the guide groove. The springs are respectively movably sleeved on the outer arc surface of the limit rod located in the same guide groove to achieve the function of stable movement.

[0008] Furthermore, it also includes a circular avoidance groove, which is arranged at the bottom end of the base to achieve the avoidance function.

[0009] Furthermore, it also includes a hexagon socket bolt, which is arranged at the lower end of the tightening cap to achieve the function of screwing in the hexagon socket.

[0010] Furthermore, it also includes reinforcing ribs, which are evenly arranged between the upper and lower inner walls of the base to achieve the function of reinforcing the base structure.

[0011] Furthermore, it also includes avoidance grooves, which are evenly arranged on the upper surface of the base, and the bottom ends of the four avoidance grooves are provided with mounting screws to achieve the function of avoiding the mounting base.

[0012] Furthermore, it also includes a reinforcing connecting frame, which is arranged on the upper surface of the base, and the middle part of the reinforcing connecting frame is fixedly connected to the outer arc surface of the support tube to achieve the dispersion of the force applied to the support tube.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the assembly structure of the fastener has the following advantages:

[0014] When fasteners and assembly operations are required, the external parts are installed on the mounting seat. At this time, the mounting seat is pushed downward until the lower surface of the mounting seat fits the upper end of the reinforcing connecting frame. During this period, the slider moves downward in the guide groove, and the limit rod, spring and slider push the slider downward. At this time, the threaded column leaks out, and the tightening cap can be manually screwed on through the threaded opening and the threaded column. The leaked length of the threaded column is equal to the length of the threaded opening in the tightening cap. At this time, the top joint is tightly attached to the lower end of the inner arc surface of the support tube, and then the base is installed to the designated work station through the external bolts and the mounting screws. During the project in which the external parts are used, the external forces received will be dissipated to the support tube, and then these forces will be dissipated to the reinforcing connecting frame. Then the base receives these forces, and then the reinforcing ribs bear them, thereby realizing the function of fastening and assembly. The structure of the fastener has strong stability and fast assembly speed. BRIEF DESCRIPTION OF THE DRAWINGS
