Abstract
The utility model relates to the technical field of elevator accessory manufacturing, and aims to provide a novel spinning plunger barrel that is used for an elevator bumper, and can improve the strength of a plunger barrel component and reduce the manufacturing cost. The spinning plunger barrel comprises a plunger barrel body, wherein a nozzle is arranged at the top of the plunger barrel body; the bottom wall of the plunger barrel body extends outwards to form a connecting part; the tail end of the connecting part further extends outwards to form a spring seat, and the initial end of the connecting part further extends toward the interior of the plunger barrel to form an end cover. By the addition of the end cover, the spinning plunger barrel modifies an original component integrated by four functional structures (the nozzle, the plunger barrel, the connecting part and the spring seat) into a component integrated by five functional structures, so that corresponding connecting points are reduced, the structural strength of the component itself is improved, and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to elevator accessory manufacturing technology field, especially relates to a kind of novel rotary extrusion plunger barrel for buffer of elevator.
Background technology
In Chinese utility model patent specification sheets CN201120125656.8, a kind of spinning plunger barrel for elevator buffer is disclosed, this spinning plunger barrel for elevator buffer is integrated original 4 functional structures (nozzle, plunger barrel, attaching parts, a spring perch) part, reduce corresponding point of connection, the structural strength of raising own, has reduced productive costs.But the parts end cap of plunger barrel still need to combine with welding or the mode being threaded, and belongs to the simple superposition of general structure sexual function parts, cost is higher.
Utility model content
For solving the problems of the technologies described above, the utility model provides one can improve plunger barrel strength of parts, reduces the novel rotary extrusion plunger barrel of cost of manufacture.
The novel rotary extrusion plunger barrel of the utility model, comprise plunger barrel cylindrical shell, the top of described plunger barrel cylindrical shell is provided with nozzle, the diapire of described plunger barrel cylindrical shell outwards forms a connecting portion, the end of this connecting portion stretches out and forms a spring perch, and the top of this connecting portion extends to form an end cap again in cylinder.
Concrete, described connecting portion, spring perch, end cap and plunger barrel cylindrical shell are formed in one.
Concrete, described nozzle and plunger barrel cylindrical shell are formed in one.
Compared with prior art, the beneficial effects of the utility model are: adding end cap in part integrated 4 functional structures of former cause (nozzle, plunger barrel, attaching parts, spring perch), be transformed into by 5 parts that functional structure is integrated, reduce corresponding point of connection, the structural strength of raising own, has reduced productive costs.
Brief description of the drawings
Fig. 1 is the structural representation of former spinning plunger barrel for elevator buffer;
Fig. 2 is the structural representation of the novel rotary extrusion plunger barrel of the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Shown in Figure 2, the novel rotary extrusion plunger barrel of the utility model, comprise plunger barrel cylindrical shell 1, the top of plunger barrel cylindrical shell 1 is provided with nozzle 2, the diapire of described plunger barrel cylindrical shell 1 outwards forms a connecting portion 3, the end of this connecting portion 3 stretches out and forms a spring perch 4, and the top of this connecting portion 3 extends to form an end cap 5 again in 1 of plunger barrel cylindrical shell.
Wherein, nozzle 2, connecting portion 3, spring perch 4, end cap 5 are formed in one with plunger barrel cylindrical shell 1.
The novel rotary extrusion plunger barrel of the utility model, adding end cap in part integrated 4 functional structures of former cause (nozzle, plunger barrel, attaching parts, spring perch), be transformed into by 5 parts that functional structure is integrated, reduce corresponding point of connection, the structural strength of raising own, has reduced productive costs.
Comprise the above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
