Description
The technical field is as follows:
the utility model relates to a mechanical field's connecting elements's packing ring especially relates to a packing ring that is used for two structures on the connecting bolt.
Background art:
the connecting and fastening body is a connecting piece which is widely used, the using amount is huge, the gasket is a fitting part of the fastening piece, the common gasket is in a ring-sheet structure with a through hole in the center, and after the bolt passes through the through hole, the nut on the bolt is screwed to clamp the gasket and connect the fastening pieces. However, when the member to be connected is a box-shaped member or a hollow cylinder such as a steel pipe or a large member, the installation and use of the above-mentioned fastener are very inconvenient, and especially, the gasket is difficult to be assembled through the through hole of the member to be connected. In order to solve the difficulties, a deformable sectional gasket is designed, for example, a circular gasket is formed by four sections of arc gaskets, a rubber ring is arranged outside the circular gasket to restrain the four sections of arc gaskets to form an integrated circular gasket, when the deformable sectional gasket is used, a relative external force is applied outside a symmetrical connecting seam of the circular gasket, the gasket can deform a flattened jujube-kernel shape, namely a short shaft is arranged, the jujube-kernel shape can pass through the through hole on the fastener, once the deformed circular gasket passes through the through hole, the original state is recovered under the action of the circumferential external force applied by the rubber ring, the nut can be screwed, and the use of the one-way bolt is realized. The sectional type gasket has some defects, such as the deformed gasket cannot restore under the action force of the rubber ring, that is, two adjacent gasket sections can be dislocated or even break away, so that the friction effect of the gasket is greatly reduced or fails, and a certain section of gasket can break away before use to cause loss. Therefore, it is a significant task to improve the design of gaskets for mass use to overcome the aforementioned drawbacks and reduce the cost.

The specific implementation mode is as follows:
the detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings, and it should be noted that the detailed description of the embodiments is provided for the purpose of facilitating the comprehensive understanding of the technology of the present invention, and should not be construed as limiting the scope of the claims of the present invention.
Referring to fig. 1 to 5, the technical solution of the embodiment of the present invention is: the two-piece gasket 5 is a circular gasket formed by splicing two semicircular rings 1, a connecting elastic part 2 is arranged on the annular surface of the circular gasket, and a chamfered edge or an arc section (not shown in the figure) is arranged at the contact edge of the two semicircular rings 1 on one side of the connecting elastic part 2. When in use, referring to fig. 5, the two-piece washer 5 is sleeved on the installation tool 6 and then folded, and the installation tool 6 is kept in a folded state, at this time, the radial dimension of the two-piece washer 5 is reduced to half of the original outer diameter dimension, the installation tool 6 is pushed in the direction of an arrow P shown in fig. 5, the front end of the installation tool 6 passes through a through hole 8 on a component 7 to be connected and then is connected with a screw rod 9 of the unilateral bolt, the installation tool 6 is continuously pushed in the direction of the arrow P so that the two-piece washer 5 passes through the through hole 8, the installation tool 6 is slightly rotated so that the two-piece washer 5 in the folded state is restored to a flattened state under the action of the elastic force of the connecting elastic element 2, then the installation tool 6 is pulled to move in the direction opposite to the arrow P, and then a nut at one end of the unilateral bolt pushes the two-piece washer 5 sleeved on the, the nut 10, which is fitted on the mounting tool 6, is pushed onto the threaded rod 9 and the nut 10 is screwed onto the threaded rod 9 until the component 7 to be connected is firmly connected, the other parts of which are not described in detail in fig. 5. The contact edge of the two semicircular rings 1 on one side of the connecting elastic member 2 is provided with a chamfered edge or an arc section (not shown in the figure), when the two semicircular rings 1 are bent, deformed or restored, due to the chamfered edge or the arc section, the two semicircular rings 1 cannot generate mutual interference between vertical angles, so that the bending deformation or the restoration process is very smooth.
The connecting elastic part 2 is in a circular ring shape, the outer diameter of the circular ring-shaped connecting elastic part 2 is smaller than the outer diameter of the two-piece type gasket 5, the inner diameter of the connecting elastic part 2 is smaller than the inner diameter of the two-piece type foldable gasket 5 (shown in fig. 1), or the inner diameter and the outer diameter of the circular ring-shaped connecting elastic part 2 are the same or basically the same as the inner diameter and the outer diameter of the two-piece type gasket 5, and the connecting elastic part 2 is matched with a nut at one end of the screw rod 9 of the single-; the connecting elastic piece 2 is two strip-shaped elastic pieces which are respectively arranged across the contact seams 3 on the surfaces of the two semicircular rings 1, and the strip-shaped elastic pieces are also used for connecting the two semicircular rings 1 and can be restored to a flat state after the two semicircular rings 1 are bent.
The contact surface of the circular ring washer and the connecting elastic element 2 is provided with a concave part (not shown in the figure) which is matched with the shape of the connecting elastic element 2, the connecting elastic element 2 is embedded into the concave part, and the two-piece foldable washer 5 is in rigid contact with the component 7 and a nut at one end of the screw 9 and increases friction force and tightness when the component 7 to be connected is connected. The connecting elastic member 2 is made of a thin steel sheet or an elastic plastic sheet, so that good elasticity of the connecting elastic member 2 is ensured to enable the two-sheet foldable washer 5 in a bent state to be easily in a flat state and to enable connection to have a good effect, or the connecting elastic member 2 is made of a composite steel wire plastic sheet formed by at least two thin steel wires or a net shape woven by a plurality of thin steel wires and plastic, particularly, the strip-shaped elastic sheet is made of the composite steel wire plastic sheet, so that good bending performance and high elasticity are ensured, and the punched composite steel wire plastic sheet has excellent manufacturability and material saving.
For improving the utility model discloses effect when using on unilateral bolt semicircle ring 1 for setting up another surface of connecting elastic component 2 surfaces and be equipped with the semicircle convex part 4 that an external diameter is less than semicircle ring 1 external diameter, then during the installation, annular convex part on foretell semicircle convex part 4 or the ring shape packing ring can 2 imbed in the aforesaid through-hole 8 on the component 7 of treating the connection, can improve two formula collapsible packing rings 5's stability.
