Abstract
The utility model discloses a dryer strains a section of thick bamboo convenient to loading and unloading, including straining a section of thick bamboo body, the top outside of straining a section of thick bamboo body is equipped with polygon protruding portion or polygon recess, just the central line of polygon protruding portion or polygon recess with strain the coincidence of the central line of a section of thick bamboo body. The utility model adds the polygonal protruding part or the polygonal groove on the top of the existing filter cylinder body, so that tools such as a common wrench and the like can obtain corresponding force application points on the filter cylinder body, and the filter cylinder body can be rotated by using the tools such as the common wrench and the like to be separated from the valve body, so that the filter cylinder is convenient to disassemble and assemble, does not need special tools, and greatly saves the maintenance cost; meanwhile, the tightening torque can be accurately controlled to meet the design requirement, and leakage caused by improper damage of the dryer due to the use of the strap wrench is avoided; in addition, tools such as a common wrench are adopted, the requirement on the disassembly and assembly space is low, and the whole vehicle is convenient to arrange and refit.
Description
Technical field
The utility model relates to a kind of drier filter cylinder of gas braking vehicle, refers to particularly a kind of drier filter cylinder of being convenient to load and unload.
Background technology
Drier is air braking system gas to be carried out the device of removal moisture drying, oil removing cleaning, and as shown in Figure 1, it is comprised of valve body 1 and filter cylinder body 2 two parts, and between filter cylinder body 2 and valve body 1, the employing internal thread is connected.In filter cylinder body 2, drier is housed, drier needs time-based maintenance to change, and it can be regenerated within certain time limit reuse, and separates filter cylinder body 2 and valve body 1 when changing drier, with its taking-up.Adopt the face of cylinder of band spanner banding filter cylinder body 2 during prior art dismounting filter cylinder body 2, carry out dismounting after making its rotation, the problem that the method exists is:
One, the face of cylinder of filter cylinder body 2 is comparatively smooth, even utilize the band banding, also easily skids during dismounting;
Two, use the band spanner to be not easy to control screw-down torque, easily loosening when moment is inadequate, and the excessive internal thread that easily damages of moment either way may cause filter cylinder body 2 and the junction of valve body 1 to leak gas;
Three, the band spanner belongs to specific purpose tool, has increased the additional cost of upkeep of drier;
Four, use the band spanner to need larger operating space, be unfavorable for car load layout and maintenance.
Summary of the invention
The purpose of this utility model be to overcome existing drier maintenance with the band spanner with defects, a kind of drier filter cylinder of being convenient to load and unload is provided.
For achieving the above object, the drier filter cylinder of being convenient to load and unload that the utility model is designed, comprise the filter cylinder body, the top outer of described filter cylinder body is provided with polygon protuberance or polygon groove, and the center line of the center line of described polygon protuberance or polygon groove and described filter cylinder body overlaps.
Preferably, described polygon protuberance is tetragonal nut or hex nut.
Preferably, described polygon groove is hexagonal indentations.
The beneficial effects of the utility model: the drier filter cylinder of being convenient to load and unload that provides is by installing polygon protuberance or polygon groove additional in existing filter cylinder bodies top, make instruments such as commonly using spanner obtain the point of application corresponding on the filter cylinder body, utilizing instruments such as commonly using spanner is rotatable filter cylinder body, it is separated with valve body, easy accessibility, need not special tool(s), significantly save the maintenance cost; Simultaneously can accurately control screw-down torque and meet design requirement, avoid leaking because using the improper damage drier of band spanner, producing; In addition, adopt the instruments such as spanner commonly used, low to the dismounting space requirement, be convenient to arrangement and repacking.
Description of drawings
Fig. 1 is the perspective view of drier in prior art.
Fig. 2 is the perspective view of a kind of embodiment and the state of use of the utility model drier filter cylinder of being convenient to load and unload.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 2, a kind of drier filter cylinder of being convenient to load and unload, comprise filter cylinder body 2, the top outer projection welding of described filter cylinder body 2 has hex nut 3, and the center line of the center line of described hex nut 3 and described filter cylinder body 2 overlaps, and overlaps with the pivot of filter cylinder body 2 to guarantee its pivot.
In filter cylinder housing design or process, drier filter cylinder top is preferably is processed into the plane vertical with the axis, to facilitate hexagon weld nut 3.
During drier filter cylinder that use is convenient to load and unload, when only needing to adopt common spanner to turn hex nut 3, can drive filter cylinder body 2 and rotate together, make itself and valve body 1 disengaging, or be arranged on valve body 1.
A kind of drier filter cylinder of being convenient to load and unload, comprise the filter cylinder body, the top outer projection welding of described filter cylinder body has hexagonal socket nut, and the coincidence of the center line of the center line of described hexagonal socket nut and described filter cylinder body, overlaps with the pivot of filter cylinder body to guarantee its pivot.
During drier filter cylinder that use is convenient to load and unload, when only needing to adopt spanner with hexagonal protrusions to turn hexagonal socket nut, can drive the filter cylinder body and rotate together, itself and valve body be broken away from, or be arranged on valve body.
A kind of drier filter cylinder of being convenient to load and unload, comprise the filter cylinder body, the top outer of described filter cylinder body is provided with the hexagon protuberance, and the coincidence of the center line of the center line of described hexagon protuberance and described filter cylinder body, overlaps with the pivot of filter cylinder body to guarantee its pivot.
The hexagon protuberance can be by the outwards outstanding moulding of top that utilizes mould punching filter cylinder body in process.
During drier filter cylinder that use is convenient to load and unload, when only needing to adopt common spanner to turn the hexagon protuberance, can drive the filter cylinder body and rotate together, itself and valve body be broken away from, or be arranged on valve body.
Embodiment 4
A kind of drier filter cylinder of being convenient to load and unload, comprise the filter cylinder body, the top outer of described filter cylinder body is provided with hexagonal indentations, and the coincidence of the center line of the center line of described hexagonal indentations and described filter cylinder body, overlaps with the pivot of filter cylinder body to guarantee its pivot.
The hexagonal indentations moulding that can cave inward by the top that utilizes mould punching filter cylinder body in process.
During drier filter cylinder that use is convenient to load and unload, when only needing to adopt spanner with hexagonal protrusions to turn hexagonal indentations, can drive the filter cylinder body and rotate together, itself and valve body be broken away from, or be arranged on valve body.
The shape that the utility model employing energy and spanner commonly used match is as top protuberance or the groove of filter cylinder body, to obtain the effect of conveniently assemble and disassemble.So except the hexagon protuberance; other are convenient to stressed tetragonal nut, anistree projection; or all should be considered as distortion of the present utility model in the part that filter cylinder body top punching press cross groove etc. can be stressed; that the common technology means that those skilled in the art easily expect are replaced, within dropping on protection domain of the present utility model.
