Abstract
The utility model provides a slide bushing, which comprises an accommodating through hole, wherein the accommodating through hole comprises a first part and a second part which penetrate through each other; the cross sectional area of the first part is greater than the cross sectional area of the second part; and the inner side wall of the first part is provided with a lining. Compared with the prior art, the slide bushing provided by the utility model has the advantages that the accommodating through hole for accommodating a slide rod is arranged into the first part and the second part and the lining is arranged on the larger first part, so that the lining fixation effect is better, the lining is prevented from falling during movement of the slide rod, and the failure rate of mechanical equipment using the slide bushing is reduced.
Description
Technical field
The utility model relates to the mechanical fitting field, relates in particular to a kind of sliding sleeve.
Background technique
Along with the high speed development of modern industry, all adopt slide bar to cooperate assembling with sliding sleeve in the machinery between the movable part, thereby guaranteed the efficient of the two slip.
Existing sliding sleeve all center has perforate, slide bar is placed through this perforate and slides among this perforate, smooth and easy for what guarantee to relatively move between slide bar and the sliding sleeve, usually the madial wall in the sliding sleeve perforate arranges lining, improve the smooth degree that slide bar and sliding sleeve relatively move, yet this liner easily breaks away from the sliding sleeve perforate, causes and uses the machinery of sliding sleeve to break down, and then cause potential safety hazard.
Therefore, be necessary to propose a kind of new sliding sleeve to address the above problem.
The model utility content
The utility model provides a kind of lining to be fixed in the sliding sleeve of accommodating through hole.
For solving above-mentioned model utility purpose, the utility model provides a kind of sliding sleeve, it comprises accommodates through hole, describedly accommodate first portion and the second portion that through hole comprises mutual perforation, described first portion cross-section area is greater than described second portion cross-section area, and the madial wall of described first portion is provided with lining.
As further improvement of the utility model, described lining is annulus, and the outer surface of described lining and the inner surface of described first portion fit tightly.
As further improvement of the utility model, the cross section of described first portion is circular.
As further improvement of the utility model, the cross section radius of described first portion is 150 millimeters.
As further improvement of the utility model, the cross section of described second portion is circular.
As further improvement of the utility model, the cross section radius of described second portion is 50 millimeters.
As further improvement of the utility model, the thickness of described lining is 100 millimeters.
As further improvement of the utility model, described lining is the copper material preparation.
Compared with prior art, sliding sleeve provided by the utility model, be set to first portion and second portion by the through hole of accommodating of accommodating slide bar, and lining is arranged at larger first portion, the better effects if of stationary bushing, avoid lining in the slide bar moving process, to come off, reduced the rate of fault of the machinery of using this sliding sleeve.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the sectional view of sliding sleeve among the utility model one embodiment.
Wherein, reference character is:
Sliding sleeve, 100; Accommodate through hole, 10; First portion, 11; Second portion, 12; Lining, 13.
Embodiment
Below with reference to each embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.
Join shown in Figure 1, the utility model provides a kind of sliding sleeve 100, it comprises accommodates through hole 10, describedly accommodate first portion 11 and the second portion 12 that through hole 10 comprises mutual perforation, described first portion 11 cross-section areas are greater than described second portion 12 cross-section areas, and the madial wall of described first portion 11 is provided with lining 13.
Wherein, described lining 13 is annulus, and the inner surface of the outer surface of described lining 13 and described first portion 11 fits tightly.
In the present embodiment, the cross section of described first portion 11 is circular; The cross section of described second portion 12 is circular.
Corresponding, its cross section of slide bar that cooperates sliding sleeve 100 also be circle, thereby so that slide bar to enter the efficient of accommodating through hole 10 higher, improved the efficient of its combination.
Concrete, the cross section radius of described first portion 11 is 150 millimeters; The cross section radius of described second portion 12 is 50 millimeters.
Corresponding, the thickness of described lining is 100 millimeters, thereby guaranteed that first portion 11 is after adding lining 13, its internal diameter size equates with the radius of the cross section of described second portion 12, thereby so that slide bar is being accommodated held stationary among the through hole 10, can not cause slide bar to move and have some setbacks because of having added lining 13, and then affect the normal use of sliding sleeve 100.
Especially, described lining 13 is the copper material preparation.
Concrete, described lining 13 has improved the packaging efficiency of sliding sleeve 100 by being fixed in the inner surface of first portion 11 by the mode such as gluing.
Compared with prior art, sliding sleeve 100 provided by the utility model, be set to first portion 11 and second portion 12 by the through hole 10 of accommodating that will accommodate slide bar, and lining 13 is arranged at larger first portion 11, the better effects if of stationary bushing 13, avoid lining 13 in the slide bar moving process, to come off, reduced the rate of fault of the machinery of using this sliding sleeve 100.
Be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility mode of execution of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
