Abstract
The utility model relates to a lifting barrel used for a spiral jack, which comprises a barrel body and a steel wire circle clip. A barrel inner hole and a nut matching hole are disposed in the barrel body and are communicated mutually, the inner diameter of the nut matching hole is larger than that of the barrel inner hole, a nut is disposed in the nut matching hole, the outer surface of the barrel body is provided with an elongated slot, a circle clip groove is arranged on the outer side of the nut matching hole on the barrel body, and the steel wire circle clip is clamped in the circle clip groove and matches with the same. The lifting barrel is reasonable in structural design, can greatly save raw materials required by manufacturing the barrel body, reduces machining time, increases production efficiency, is better in quality after the surface of the barrel body is ground, and simultaneously is more convenient in assembling.
Description
Technical field
The utility model relates to a kind of lifting tube that is used for lifting screw, belongs to major part in the lifting screw.
Background technology
The lifting tube of jack all is provided with a step in the prior art, in general the diameter of step is than the big 3mm of lifting tube barrel diameter, can prevent that lifting tube from skidding off jack rising too high, but but there is very big problem in actual production process, mainly show the following aspects: 1. the blank of lifting tube processing is a tubing, need process step need be by the thickness of the minimum 3mm of turning, and the length of the cylindrical shell of lifting tube is also longer, not only processing is comparatively time-consuming, the production efficiency capacity utilization rate is lower, and the degree of utilization of blank is low, and it is serious to decrease material, and productive costs is too high; 2. because the accuracy requirement of the barrel outer surface of lifting tube is very high, need carry out ground finish, but, make the surface quality of processing relatively poor because of the existence of step, can not fine satisfied assembling requirement, perhaps jack in use influences the single-piece performance.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provide a kind of reasonable in design, can enhance productivity effectively, save the resources of production simultaneously, and the lifting tube that is used for lifting screw that can improve the quality of products.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of lifting tube that is used for lifting screw, comprise cylindrical shell, and it is characterized in that: it also comprises wire circlip; Be provided with cylindrical shell endoporus and nut mating holes in the described cylindrical shell; Cylindrical shell endoporus and nut mating holes interconnect, and the internal diameter of nut mating holes is greater than the internal diameter of cylindrical shell endoporus; Have elongated slot on the outside face of cylindrical shell; The cylindrical shell in the nut mating holes outside is provided with the jump ring groove, and wire circlip snaps in the jump ring groove, and matches each other.
The external diameter of wire circlip described in the utility model is greater than the external diameter of lifting tube cylindrical shell.
Be provided with nut in the nut mating holes described in the utility model, nut and nut mating holes are complementary, and fix by straight pin.
Straight pin described in the utility model has two.
Barrel outer surface described in the utility model is provided with the warning groove.
The utility model compared with prior art has following positive effect: reasonable in design, and can save greatly and make the required raw MAT'L of cylindrical shell, reduce the time of machine up, enhance productivity, the surface of cylindrical shell quality after ground finish is better, and the assembling of lifting tube is more convenient simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model half section.
Fig. 2 be among Fig. 1 A-A to the sectional structure scheme drawing.
Fig. 3 is for removing the structural representation behind nut and the wire circlip among Fig. 1.
Among the figure: 1 cylindrical shell, 2 wire circlips, 3 cylindrical shell endoporus, 4 nut mating holess, 5 elongated slots, 6 jump ring grooves, 7 nuts, 8 straight pins, 9 warning grooves.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment: referring to Fig. 1-3, present embodiment mainly is made up of cylindrical shell 1 and wire circlip 2, is provided with cylindrical shell endoporus 3 and nut mating holes 4 in the cylindrical shell; Cylindrical shell endoporus 3 and nut mating holes 4 interconnect, and the internal diameter of nut mating holes 4 is greater than the internal diameter of cylindrical shell endoporus 3; Have elongated slot 5 on the outside face of cylindrical shell 1, can prevent that lifting tube from following screw rod to rotate; The cylindrical shell 1 in nut mating holes 4 outsides is provided with jump ring groove 6, and wire circlip 2 snaps in jump ring groove 6, and matches each other; The external diameter of wire circlip 2 is greater than the external diameter of lifting tube cylindrical shell 1.
In the present embodiment, be provided with nut 7 in the nut mating holes 4, nut 7 is complementary with nut mating holes 4, and fixing by straight pin 8; The straight pin 8 that is provided with in the present embodiment has two.
In the present embodiment, the design of wire circlip 2 is compared and the design of original step, has saved greatly and has made the required raw MAT'L of cylindrical shell 1, reduce the time of machine up, enhance productivity, the assembling of this lifting tube simultaneously is convenient, and the surface of cylindrical shell 1 quality after ground finish is better.
In addition, need to prove, specific embodiment described in this specification sheets, as long as the undeclared concrete shape and size of its part, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
