Description

Flip structure

Technical Field

The utility model is applied to the technical field of flip covers, and particularly relates to a flip cover structure.

Background

The flip structure is a commonly used connection structure, and generally includes a cover plate and a base, wherein the cover plate is rotatably fitted on the base through a rotating shaft, so as to realize the turning action of the cover plate on the base. Wherein, need set up two mounting holes with the pivot is endocentric in the both sides of base for the assembly pivot, and the tip of pivot need pass the mounting hole, thereby avoid the apron to appear the problem that the pivot breaks away from in long-time upset operation, but such design, the assembly of pivot can be more difficult, and later stage also is not convenient for dismantle the apron get off and maintain. If a flip structure with simple structure and easy disassembly and assembly can be designed, the problems can be well solved.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a flip structure which is simple in structure and convenient to disassemble and assemble.

The technical scheme adopted by the utility model is as follows: the novel screw-thread connecting structure comprises a base, a cover plate, two gaskets and two screws, wherein two mounting holes are formed in the base, a rotating shaft is arranged on the cover plate, two ends of the rotating shaft are respectively matched in the two mounting holes, the gaskets are matched in the mounting holes, the end part of the rotating shaft is located between the base and the gaskets, and the screws penetrate through the gaskets and are in threaded connection with the base.

Further, the base comprises a bottom plate and two positioning blocks, the two positioning blocks are respectively arranged at the left end and the right end of the base, and the two mounting holes are respectively arranged on the two positioning blocks.

Further, the mounting hole includes the counter sink and is close to the constant head tank of counter sink, the tip adaptation of pivot is in the constant head tank, the gasket adaptation is in the counter sink, the tip of pivot is located the locating piece with between the gasket, the screw passes behind the gasket with counter sink screw-thread fit.

Furthermore, the bottom of the positioning groove is semicircular, and the radius of the bottom of the positioning groove is equal to that of the rotating shaft.

Further, the gasket is circular ring-shaped, be provided with spacing piece on the gasket, spacing piece with the positioning groove looks adaptation, the tip of pivot still is located the locating piece with between the spacing piece.

The utility model has the beneficial effects that: when assembling, firstly install the both ends of pivot respectively in two in the mounting hole to the restriction apron is at X axle and the ascending degree of freedom of Y axle direction, again with two the gasket is installed respectively in two in the mounting hole, then utilize the screw pass behind the gasket with base threaded connection fixes the gasket, thereby makes the gasket can restrict the apron is at the ascending degree of freedom of Z axle direction, ensures the apron only can round the pivot overturns. When the cover plate is required to be disassembled, only two screws are required to be disassembled, and then two gaskets are required to be disassembled, so that the cover plate can be disassembled, and the maintenance is convenient. Therefore, the utility model has the advantages of simple structure, convenient and quick assembly and disassembly, high working efficiency, convenience for later maintenance and strong practicability.

Detailed Description

As shown in fig. 1 to 3, in this embodiment, the present invention includes a base, a cover plate 1, two gaskets 2, and two screws 3, where two mounting holes are provided on the base, a rotating shaft 4 is provided on the cover plate 1, two ends of the rotating shaft 4 are respectively fitted in the two mounting holes, the gaskets 2 are fitted in the mounting holes, an end of the rotating shaft 4 is located between the base and the gaskets 2, and the screws 3 are threaded with the base after penetrating through the gaskets 2.

In this embodiment, the base includes bottom plate 5 and two locating pieces 6, two locating pieces 6 set up respectively the both ends about bottom plate 5, two the mounting hole is established respectively two on locating piece 6.

In this embodiment, the mounting hole includes counter bore 7 and is close to counter bore 7's constant head tank 8, the tip adaptation of pivot 4 is in constant head tank 8, gasket 2 adaptation is in counter bore 7, the tip of pivot 4 is located locating piece 6 with between the gasket 2, screw 3 passes behind the gasket 2 with counter bore 7 screw-thread fit.

In this embodiment, the bottom of the positioning groove 8 is semicircular, and the radius of the bottom of the positioning groove 8 is equal to the radius of the rotating shaft 4.

In this embodiment, the height from the bottom of the counter sink 7 to the bottom of the positioning slot 8 is equal to the diameter of the rotating shaft 4.

In this embodiment, the gasket 2 is circular, the gasket 2 is provided with a limiting piece 9, the limiting piece 9 is matched with the positioning groove 8, and the end of the rotating shaft 4 is also located between the positioning block 6 and the limiting piece 9.

In this embodiment, the counter sink 7 and the positioning groove 8 are close to each other and both have upward openings, thereby simplifying the production mold, reducing the manufacturing cost, and improving the production efficiency.

In this embodiment, when the present invention is assembled, two ends of the rotating shaft 4 are respectively installed in the two positioning grooves 8, so as to limit the degrees of freedom of the cover plate 1 in the X-axis and Y-axis directions, the two gaskets 2 are respectively installed in the two countersunk holes 7, and the screws 3 are threaded through the gaskets 2 and then are in threaded fit with the countersunk holes 7, so as to fix the gaskets 2, so that the gaskets 2 can limit the degrees of freedom of the cover plate 1 in the Z-axis direction, and ensure that the cover plate 1 can only be turned around the rotating shaft 4.

In this embodiment, when the present invention is disassembled, only two screws 3 need to be disassembled, and then two gaskets 2 need to be removed, so that the cover plate 1 can be disassembled from the base, which is convenient for maintenance. Therefore, the utility model has simple structure, simple and convenient and quick disassembly and assembly, is convenient for later maintenance, greatly improves the working efficiency and has strong practicability.
