Abstract
A pipe fitting connection device comprises a box body, an inner taper sleeve, an elastic sleeve and a tapered press plate, wherein the inner taper sleeve is installed in the box body, the elastic sleeve is in clearance fit with the box body, the tapered press plate is connected with the box body, and the outer edges of two ends of the elastic sleeve are tapered and matched with the inner taper sleeve and the tapered press plate respectively. The pipe fitting connection device has the advantages of being reasonable in structural design, used for installation of different-diameter pipe fittings and the like.
Description
Technical field:
The utility model belongs to graden machine equipment pipe connection area, specifically a kind of pipe connecting device for being connected with similar mechanically actuated bars such as brush cutter, high bar saws.
Background technique:
Brush cutter is a kind of by the driving of afterbody petrol engine, the cutting mechanism high speed rotating of live axle drive head in connecting tube, thus make the graden machine that beating the grass in cutting mechanism restricted or the blade high speed rotating is cut.Along with the high speed development of domestic horticultural machinery, various cutting mechanism is as Gao Zhiju, and the application such as branches of tall trees Green fence cutter is more and more extensive.But above-mentioned cutting mechanism only can be arranged on the connecting tube of single diameter.The user, when using different cutting mechanisms to carry out the gardens operation, must take cutting mechanism into account whether identical with the installation diameter of connecting tube, and when the different cutting mechanisms of replacing carry out operation, user's cost increases, and makes convenience have a greatly reduced quality.Therefore, be necessary to be improved.
The model utility content:
Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of reasonable in design is provided, the pipe connecting device that can be installed the different-diameter pipe fitting.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of pipe connecting device, comprise casing, inner conical drogue, elastic sleeve and conical pressure plate, described inner conical drogue is arranged in described casing, described elastic sleeve and described casing Spielpassung, described conical pressure plate is connected with described casing, and described elastic sleeve two ends outer rim is tapered and with described inner conical drogue and conical pressure plate, coordinate respectively.
Have a plurality of grooves on described elastic sleeve.
Described conical pressure plate is connected with described casing by screw.
The utility model has following advantage with respect to prior art:
Connecting tube is held in the radial force compressing elastic sleeve distortion that relies on screw to connect generation tightly, because elastic sleeve can provide higher frictional force, can guarantee that pipe fitting connects, and has groove on elastic sleeve to guarantee its amount of deformation, can adapt to the connecting tube of different-diameter.
The accompanying drawing explanation:
Fig. 1 is cross-sectional schematic of the present utility model.
Embodiment:
Referring to Fig. 1, a kind of pipe connecting device provided according to the utility model, comprise casing 1, inner conical drogue 2, elastic sleeve 3 and conical pressure plate 4, inner conical drogue 2 is arranged in casing 1, elastic sleeve 3 and casing 1 Spielpassung, conical pressure plate 4 is connected with casing 1, and elastic sleeve 3 two ends outer rims are tapered and with inner conical drogue 2 and conical pressure plate 4, coordinate respectively, have a plurality of grooves on elastic sleeve 3, conical pressure plate 4 is connected with described casing 1 by screw.Connecting tube is held in radial force compressing elastic sleeve 3 distortion that rely on screw to connect generation tightly, because elastic sleeve 3 can provide higher frictional force, can guarantee that pipe fitting connects, and has groove on elastic sleeve 3 to guarantee its amount of deformation, can adapt to the connecting tube of different-diameter.
Above-described embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that do not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technological schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
