Abstract
The utility model provides a plastic piece assembly with a cold plug piece. By the adoption of the plastic piece assembly with the cold plug piece, the problems that due to the fact that an existing cold plug piece is lower than a plastic piece to a certain extent, a seal ring cannot be protected, the rebounding function cannot be achieved, and ineffective assembly is prone to occurrence are solved. The plastic piece assembly with the cold plug piece comprises the cold plug piece of a tubular structure, a plastic piece body arranged on the cold plug piece in a sleeved mode, a seal ring arranged at the lower end of the plastic piece body and a matching body which is close to the lower end of the plastic piece body and is connected with the plastic piece body through a bolt structure. The cold plug piece is higher than the plastic piece body, and the height difference between the cold plug piece and the plastic piece body is a preset value. When the clod plug piece moves downwards along with the bolt structure, the distance between the lower end of the plastic piece body and the seal surface of the matching body gradually becomes smaller, so that the seal ring is attached to the seal surface of the matching body, and the cold plug piece moves downwards until the clod plug piece protrudes out of the lower end of the plastic piece body for a certain distance. By the adoption of the plastic piece assembly with the cold plug piece, the protective function is achieved on the seal ring in the plastic piece body, and a certain rebounding function is achieved.

Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearer, be described in detail below in conjunction with specific embodiment and accompanying drawing.
The utility model embodiment solve existing cold plug-in unit due to lower than working of plastics body certain altitude can not to seal ring play a protective role and existing cold plug-in unit can not play rebound effect easily cause assembling lost efficacy problem, the utility model embodiment provides a kind of cold plug-in unit, comprise: as depicted in figs. 1 and 2, cold plug-in unit 1 in tubular construction, this cold plug-in unit 1 is metallic material; As shown in Figure 3, be sheathed on the working of plastics body 2 on described cold plug-in unit 1, concrete, working of plastics body 2 can be intake manifold body; Close working of plastics body 2 lower ends and the ligand 5 being connected with working of plastics body 2 by bolt arrangement 4; Further, in order to ensure the sealing between working of plastics body 2 and ligand 5, the lower end of working of plastics body 2 is provided with seal ring 3, and general seal ring 3 is rubber material, and has certain decrement; Wherein, as shown in Figure 3 and Figure 5, the height h of cold plug-in unit 1 exceeds predeterminable range value than working of plastics body 2, cold plug-in unit 1 with bolt arrangement 4 folding processes in, distance between the sealing surface of the lower end of working of plastics body 2 and ligand 5 reduces gradually, seal ring 3 and the sealing surface of ligand 5 are fitted, reach predeterminable range value until cold plug-in unit 1 protrudes from the lower end of working of plastics body 2.
The utility model embodiment's working of plastics assembly, by adopting the cold plug-in unit 1 that exceeds predeterminable range with respect to working of plastics body 2, seal ring 3 is reasonably being sealed within the scope of impacting force, prevent that the long-time excess compression of seal ring 3 from causing plastic deformation and causing seal failure, cold plug-in unit 1 of the present utility model, in long-term using process, can discharge spring-back force and make up bolt pretightening disappearance and cause assembling to lose efficacy in the time of bolt looseness simultaneously.
In the utility model embodiment, described predeterminable range value is greater than 0mm and is less than 0.5mm.Concrete, the height that cold plug-in unit 1 exceeds working of plastics body 2 will design according to the decrement of seal ring 3.
In prior art, as shown in Fig. 4, Fig. 6 and Fig. 7, because the height of existing cold plug-in unit is lower than working of plastics body 2, in the process moving down at bolt arrangement 4, close contact between working of plastics body 2 and ligand 5, the part that seal ring 3 is protruded to working of plastics body 2 is compressed completely, voidlessness between working of plastics body 2 and ligand 5, and bolt arrangement 4 is directly pressed on working of plastics body 2, cause existing cold plug-in unit can not discharge spring-back force, also cause in addition seal ring 3 because long-term excess compression causes plastic deformation.And in the utility model embodiment, as shown in Figure 8 and Figure 9, working of plastics body 2 is sheathed on cold plug-in unit 1, outstanding working of plastics body 2 certain distances of seal ring 3 of working of plastics body 2 lower ends, and bolt arrangement 4 is through the cold plug-in unit 1 and ligand 5 with identical bolt aperture.Because cold plug-in unit 1 is higher than working of plastics body 2, cold plug-in unit 1 along with bolt arrangement folding process in, distance between the sealing surface of the lower end of described working of plastics body 2 and ligand 5 reduces gradually, seal ring 3 and the sealing surface of described ligand 5 are fitted, until the lower end that cold plug-in unit 1 protrudes from working of plastics body 2 reaches predeterminable range value, now, the lower end of cold plug-in unit and the sealing surface of ligand connect, between working of plastics body and ligand, leave a fixed gap, the part that makes the outstanding working of plastics body of seal ring is also compression completely, seal ring is reasonably sealing within the scope of impacting force, prevent that the long-time excess compression of seal ring from causing plastic deformation and causing seal failure.
In addition, because cold plug-in unit 1 is higher than working of plastics body 2, in the process of bolt tightening, the effect that working of plastics body 2 does not stress, in the long-term using process of cold plug-in unit 1, cold plug-in unit 1 can discharge spring-back force, prevent assembly parts in the course of the work, get loose because bolt pretightening disappearance causes.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
