Abstract
A main oil cylinder structure of a manual pallet trunk comprises a hollow cylinder body, a cover body assembled at one end of the cylinder body, and a plunger penetrating through the cover body and the cylinder body, wherein the cylinder body is provided with an inward-shrinking lower opening and an upper opening larger than the lower opening, the cover body is assembled to the upper opening, the diameter of the lower opening is equal to that of the plunger, the cylinder body is further provided with a groove located below the lower opening, and the diameter of the groove is larger than that of the lower opening. The main oil cylinder structure of the manual pallet trunk further comprises a main oil seal located in the groove, and the main oil seal is closely attached to the plunger. The upper opening of the cylinder body of the main oil cylinder structure of the manual pallet trunk is large, and therefore the interior of the cylinder body is easy to clean, and cost is saved because the number of parts is small.
Description
[technical field]
The utility model relates to a kind of master cylinder structure of Manual Pallet Trucks.
[background technique]
The master cylinder structure of existing Manual Pallet Trucks comprises housing and is housed in oil sealing group and the plunger of enclosure interior.Due to the structure of housing be mostly young in the middle of tripe large, a kind of ampuliform structure of the thin neck of likeness in form osculum, so the dirt of cleaning enclosure interior is very inconvenient, when especially housing is cast member, the casting sand of more aobvious cleaning enclosure interior and difficult.Meanwhile, between bottleneck inwall and plunger, lining guided bearing part again, and this structural type part is more, and add also inconvenience of assembling, time-consuming, expensive, take labour, not only cost higher outside, but also being unfavorable for that production technology is brief, it is many unfavorable that production in enormous quantities is caused.
Given this, the necessary master cylinder structure that a kind of improved Manual Pallet Trucks is provided, the defect existing to overcome prior art.
[model utility content]
It is few and clear up the master cylinder structure of Manual Pallet Trucks easily that the purpose of this utility model is to provide a kind of structural reduction part.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme: a kind of master cylinder structure of Manual Pallet Trucks, the cylinder body that comprises hollow, be assembled in the lid of cylinder body one end and through the plunger of lid and cylinder body, described cylinder body is provided with the under shed that is recessed shape and the upper shed that is greater than under shed, lid is assembled to described upper shed, the diameter of under shed and the equal diameters of plunger, cylinder body is also provided with the groove that is positioned under shed below, the diameter of groove is greater than the diameter of under shed, the master cylinder structure of described Manual Pallet Trucks also comprises the main oil sealing that is positioned at groove, main oil sealing and plunger fit tightly.
The utility model further defines, and described lid and cylinder body are provided with the screw thread cooperatively interacting lid and cylinder body are fixed together.
The utility model further defines, together with described lid is welded and fixed with cylinder body.
The utility model further defines, and described cylinder body also comprises the outlet that is positioned at beneath trenches, and the diameter of outlet is greater than the diameter of under shed and is less than the diameter of groove.
The utility model further defines, and the master cylinder structure of described Manual Pallet Trucks also comprises the O shape circle between lid and cylinder body.
The utility model further defines, described lid is provided with through hole, is positioned at accommodation section and the accepting groove in through hole outside, the diameter of through hole equals the diameter of plunger, accommodation section is positioned at the below of accepting groove, in accommodation section, be assembled with secondary oil sealing, in accepting groove, be assembled with dust ring, secondary oil sealing and dust ring and plunger fit tightly.
Compare with correlation technique, the upper shed of the cylinder body of the master cylinder structure of the utility model Manual Pallet Trucks is larger, easily clears up cylinder interior and part is less, provides cost savings.

Fig. 1 is the decomposing schematic representation of the first mode of execution of the master cylinder structure of the utility model Manual Pallet Trucks.
Fig. 2 is the assembling schematic diagram of the first mode of execution of the master cylinder structure of the utility model Manual Pallet Trucks.
Fig. 3 is the assembling schematic diagram of the second mode of execution of the master cylinder structure of the utility model Manual Pallet Trucks.
[embodiment]
Consult shown in Fig. 1 to Fig. 2, the master cylinder structure of the utility model Manual Pallet Trucks comprises the cylinder body 6 of hollow, is assembled in the lid 5 of cylinder body 6 one end and the plunger 1 with cylinder body 6 through lid 5.Lid 5 and cylinder body 6 are provided with the screw thread (not indicating) cooperatively interacting lid and cylinder body are fixed together.Cylinder body 6 is provided with the under shed 61 that is recessed shape and the upper shed 62 that is greater than under shed 61.Lid 5 is assembled to upper shed 62.The equal diameters of the diameter of under shed 61 and plunger 1.Cylinder body 6 is also provided with the groove 63 that is positioned under shed 61 belows.The diameter of groove 63 is greater than the diameter of under shed 61.Cylinder body 6 also comprises the outlet 64 that is positioned at groove 63 belows.The diameter of outlet 64 is greater than the diameter of under shed 61 and is less than the diameter of groove 63.In groove 63, be assembled with main oil sealing 4, main oil sealing 4 fits tightly with plunger 1.Between lid 5 and cylinder body 6, be provided with O shape circle 7.
Lid 5 is provided with through hole 51, is positioned at the accommodation section 52 and accepting groove 53 in through hole 51 outsides.The diameter of through hole 51 equals the diameter of plunger 1.Accommodation section 52 is positioned at the below of accepting groove 53.In accommodation section 52, be assembled with secondary oil sealing 3, in accepting groove 53, be assembled with dust ring 2.Secondary oil sealing 3 fits tightly with dust ring 2 and plunger 1.
Refer to shown in Fig. 3, the lid 5 of the master cylinder structure of the utility model Manual Pallet Trucks, can be fixed together by mode and the cylinder body 6 ' of welding.
Should be understood that, the foregoing is only preferred forms of the present utility model, it not whole mode of executions, the variation of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification, is claim of the present utility model and contains.
