Abstract
The utility model discloses a piston of door closer, including the column body, there are first styletable and a second styletable in the both ends of column body shaping respectively, rack shaping connection between first styletable and the second styletable and first styletable and second styletable between form the oil pocket, protruding connecting block in the inboard protrusion shaping of first styletable and second styletable is provided with in, the tip of protruding connecting block be the cambered surface wall, the both ends inner wall of rack is the cambered surface wall circular arc of the protruding connecting block tip integrated into one piece that passes through in with, multiplicable piston of door closer's structural strength improves piston of door closer's life, avoids the direct both ends tip with column piston of door closer in both ends of its rack of piston of door closer to connect perpendicularly, and the problem of rack both ends and column piston of door closer's the easy fracture of both ends end connection department has the characteristics of structural strength height, life length.
Description
Technical field
The utility model is related to door closer production technical field and in particular to a kind of door closer piston.
Background technology
Door closer piston is integrally in the form of a column, and its two ends end connects and be formed with oil pocket by tooth bar, existing at present closes
The two ends of door device its tooth bar of piston are direct and the two ends end vertical of column door closer piston connects, in actually used process
In, tooth bar two ends are easy to crack with the two ends end junction of column door closer piston, lead to the service life of door closer piston to contract
Short.
Content of the invention
For the deficiencies in the prior art, the utility model aims to provide that a kind of structural strength is high, long service life close door
Device piston.
For achieving the above object, the utility model adopts the following technical scheme that：
Door closer piston, including cylindrical body, the two ends of cylindrical body form the first styletable and the second styletable, tooth respectively
Bar shaping is connected between the first styletable and the second styletable and formation oil pocket and the first styletable and the second styletable between, and described first
The inner side of styletable and the second styletable is protruded shaping and is provided with convex contiguous block, and the end of convex contiguous block is cambered surface wall, tooth bar
The cambered surface wall arc transition of two ends inwall and convex contiguous block end is integrally formed.
Further, the width of described convex contiguous block is identical with the width of tooth bar.
The utility model has the advantages that：
The utility model door closer piston, the inner side of its first styletable and the second styletable is protruded shaping and is provided with convex connection
Block, the end of convex contiguous block is cambered surface wall, the cambered surface wall arc transition one of the two ends inwall of tooth bar and convex contiguous block end
Body formed, there is structural strength height, long service life.
Brief description
Fig. 1 is the structural representation of the utility model door closer piston.
In figure：1st, cylindrical body；11st, the first styletable；12nd, the second styletable；13rd, tooth bar；14th, oil pocket；15th, convex connects
Block；15a, cambered surface wall.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model will be further described, in order to clearer reason
The technological thought that solution the utility model claims.
The utility model door closer piston as shown in Figure 1, including cylindrical body 1, the two ends of cylindrical body 1 form respectively
First styletable 11 and the second styletable 12, tooth bar 13 shaping be connected between the first styletable 11 and the second styletable 12 and with the first styletable
11 and second form oil pocket 14 between styletable 12, and the inner side of the first styletable 11 and the second styletable 12 is protruded shaping and is provided with convex even
Connect block 15, the end of convex contiguous block 15 is cambered surface wall 15a, the cambered surface of the two ends inwall of tooth bar 13 and convex contiguous block 15 end
Wall 15a arc transition is integrally formed.
Specifically, the width of convex contiguous block 15 is identical with the width of tooth bar 13.
Because the first styletable 11 of the utility model door closer piston and the inner side of the second styletable 12 are protruded shaping and be provided with
Convex contiguous block 15, the end of convex contiguous block 15 is cambered surface wall 15a, the two ends inwall of tooth bar 13 and convex contiguous block 15 end
Cambered surface wall 15a arc transition be integrally formed, can increase the structural strength of door closer piston, improve the use longevity of door closer piston
Life, it is to avoid direct and column door closer piston the two ends end vertical in the two ends of its tooth bar 13 of door closer piston connects, tooth bar 13
The two ends problem easy to crack with the two ends end junction of column door closer piston.
For a person skilled in the art, can technical scheme as described above and design, make other each
Plant corresponding change and deform, and all these changes and deforms the guarantor that all should belong to the utility model claim
Within the scope of shield.
