Detailed Description
In order to make the objects, technical solutions and advantages of the present technical solution more apparent, the present technical solution is further described in detail below in conjunction with the specific embodiments. It should be understood that the description is only illustrative and is not intended to limit the scope of the present technical solution.
In fig. 1 to 4, the present embodiment is exemplified by a connection manner between the main body 10 and the cover 20, and a specific structure of the present connection structure will be described in detail.
Specifically, the present embodiment proposes a connection structure without exposing a connection bolt, including a first structure body; the pin 30, the pin 30 includes the tail, shoulder 32 and head that connect sequentially, the tail of the pin 30 connects to the first structure, the shoulder 32 of the pin 30 abuts on the surface of the first structure, the back end of the head of the pin 30 is the level, and the back end of the head of the pin 30 is greater than the cross-sectional area of the shoulder 32; the first structural plate is provided with a gourd hole 21, the gourd hole 21 comprises a first area 211 and a second area 212 which are communicated with each other, the diameter of the first area 211 is slightly larger than the area of the largest cross section of the head of the pin 30, and the diameter of the second area 212 is slightly larger than the diameter of the shoulder 32 of the pin 30.
As shown in fig. 1, in this embodiment, the main body 10 is made of glass fiber reinforced plastic, the cover plate 20 is also made of glass fiber reinforced plastic, and the cover plates 20 are required to be installed on two sides of the main body 10 respectively. As shown in fig. 2, the connection structures of the cover plate 20 and the body 10 are located at the upper and lower sides of the cover plate 20, respectively.
As shown in fig. 3, the first structural body is a mounting plate 11 formed by bending a side surface of a main body 10, and a pin 30 is connected to the mounting plate 11 via a tail portion. Referring to fig. 4, the first structural plate is formed by bending the inner side of the cover plate 20, and a hoist hole 21 is formed in the first structural plate.
In this embodiment, the tail of the pin 30 is a threaded rod, and the curved surface of the head of the pin 30 is provided with a screwing groove 34 for adapting to the clamping connection of a wrench. When the pin 30 is installed, the hand-held pliers or the spanner clamps the screwing groove 34, the pin 30 can be screwed into the installation plate 11 through the screw rod 31 at the tail part, then the cover plate 20 is inserted into the lower fixed head part through the first area 211 of the gourd hole 21, the head part of the pin 30 is in a conical or frustum-shaped structure and forms a guide head 33, the guide head 33 is used for guiding the head part of the pin 30 to be inserted into the first area 211 more easily, after the rear part of the pin 30 completely passes through the first area 211, the cover plate 20 is laterally slid, and the shoulder part 32 of the pin 30 slides into the second area 212 to complete the assembly.
The shoulder 32 of the pin 30 is cylindrical in configuration so that the pin 30 fits without angular separation. The second region 212 snaps over the shoulder 32 and the first structural panel is restrained by the head of the pin 30 from falling out when removed unintentionally.
The axial length of the shoulder 32 of the pin 30 is slightly greater than the thickness of the first structural plate so that the first structural plate does not rattle.
The junction of the first region 211 and the second region 212 transitions smoothly, and sliding the shoulder 32 of the pin 30 between the first region 211 and the second region 212 is more smooth.
The connection structure is used to connect the body 10 and the cover plate 20, the body 10 having one of the first structural body or the first structural plate, and the cover plate 20 having the other of the first structural body or the first structural plate.
