Background
Clamping is a common mounting method for injection molded parts. This method has been used many years ago and is now becoming more and more important for ease of installation and cost. The clamping has the advantage of avoiding other connecting methods such as threaded connection, clamping, sticking and the like. The clamping structures are formed by adopting a die, and the clamping structures do not need to be additionally connected. In addition, if the design is proper, repeated installation and disassembly can be achieved without damaging the parts. The snap-fit structure may be designed to be disposable and reusable. The one-off snap-fit is that the parts do not need to be removed after installation. The clamping structure used for multiple times is used on occasions needing convenient disassembly.
However, the required molds for the prior art snap-fit arrangements are also relatively complex and expensive. Generally, the capital savings in assembly is greater than the added cost of the manufacturing process. There are generally three main snap-fit configurations: annular, cantilever, torsional. The connection between the two parts is critical to high precision in order to make them tight. The clamping form has no way to make the clamping form have certain pretightening force, and compared with the threaded connection, the clamping form is a main defect of clamping. Although the common screw joint can achieve a certain pretightening force, the installation is not simple and convenient. For this reason, a new scheme needs to be designed to give improvements.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a clamping piece type spiral locking piece, which solves the problems that the existing clamping structure mold is complex in structure and high in price; the pretightening force of joint structure is not enough, installs problem simple and convenient enough, satisfies the in-service use demand.
In order to achieve the purpose, the utility model provides the following technical scheme: a bayonet screw lock comprising: card nut and joint bolt, the joint bolt includes bolt board and bolt post, the bolt post is installed perpendicularly in the surface of bolt board, and evenly is provided with two guiding mechanism on the bolt post, is formed with the guide slot between two sets of guiding mechanism, and every guiding mechanism of group includes the deflector that a plurality of level set up and vertical equidistance distributes, and is adjacent leave the clearance between the deflector, the hole has been seted up at the middle part of card nut on the bolt post in the regulation of card nut, the symmetry is provided with the spacer on the inner wall of hole.
In a preferred embodiment of the present invention, both sides of the bottom surface of the guide plate protrude downward and are respectively formed with a limiting protrusion, and a limiting groove is formed between the two limiting protrusions.
In a preferred embodiment of the present invention, a fixing protrusion is formed at a middle portion of a top surface of the guide plate, the fixing protrusion is in a shape of a long strip, a distal end of the fixing protrusion extends to a surface of the bolt column, and a cross section of the fixing protrusion is in a semicircular structure.
As a preferred embodiment of the present invention, the positioning plate is of a fan-shaped ring structure, and is connected to the limiting groove on the surface of the guide plate in an embedded manner, and the back of the positioning plate is connected to the fixing protrusion in an attached manner.
As a preferred embodiment of the present invention, the surface of the card nut is symmetrically provided with circlip holes.
Compared with the prior art, the utility model has the following beneficial effects:
the clamping bolt is connected with the clamping nut through the clamping nut, the structure is simple, the manufacturing and using cost is low, the clamping nut is aligned with the clamping bolt guide groove and axially pushed to the installation position, the clamping nut rotates clockwise, the clamping nut protrudes out of the clamping and rotates into the clamping bolt groove, axial clamping is achieved, the locking force is strong, and the installation and disassembly operations are simple.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a bayonet screw lock comprising: card nut 3 and joint bolt, the joint bolt includes bolt board 1 and bolt post 2, 2 vertical installations of bolt post are in the surface of bolt board 1, and evenly be provided with two guiding mechanism on the bolt post 2, be formed with the guide slot between two sets of guiding mechanism, and the guide slot is located the outside of bolt post 2, and every guiding mechanism of group includes the deflector 7 that a plurality of level set up and vertical equidistance distributes, leave the clearance between the adjacent deflector 7, card nut 3 is adjusted on bolt post 2 and the middle part of card nut 3 has seted up hole 8, the symmetry is provided with spacer 9 on the inner wall of hole 8, spacer 9 is fixed card nut 3.
Further improved, both sides of the bottom surface of the guide plate 7 are downwards protruded and respectively form a limiting lug 4, a limiting groove 5 is formed between the two limiting lugs 4, and a positioning sheet 9 is fixed in the limiting groove 5 to limit the limiting groove, so that the card nut 3 cannot rotate.
In a further improved mode, a fixing bump 6 is formed in the middle of the top surface of the guide plate 7, the fixing bump 6 is in a long strip shape, the tail end of the fixing bump 6 extends to the surface of the bolt column 2, the cross section of the fixing bump 6 is in a semicircular structure, and the fixing bump 6 supports a positioning sheet 9 in the limiting groove 5 to prevent the positioning sheet from moving out of the limiting groove 5.
