Description
Technical field
The utility model relates to mop and manufactures field, especially relates to a kind of guide post for mop rod.
Background technology
Mop after using needs the mop of mophead to clean, after cleaning, need to wring out, existing many mechanical dewater units of wringing out on existing market, but be all generally that parts are more, as Chinese patent CN202122554, it discloses a kind of hand dewatering device, comprise spiral grooves housing, lead, axle core and helical guide, axle core inserts lead, lead lower end is provided with the brake component being enclosed within on axle core, rotation guiding element he in axle core lower end, brake component cooperatively interacts with rotating between guiding element, realizes single-direction transmission; This structure is easy for installation, can change the parts of damage, but parts is more, fragile, especially the cooperation between helical guide and brake component need to connect by axle core, easily produce and rock, and the tooth ratio of leading of engagement is between the two easier to wearing and tearing when operation; When product is installed, and axis of guide core is thinner, and easy distortion while repeatedly pressing has downwards been used after a period of time with regard to not working.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, and a kind of guide post for mop rod of stable, not fragile, long service life is provided.
To achieve these goals, the utility model is by the following technical solutions: a kind of guide post for mop rod, the detent and one that comprise the body of rod, is positioned at the body of rod one end can have the revolving part that the housing of spiral grooves rotates in inwall, described detent comprises the braking surface that can coordinate with revolving part spline and the projection that can move up and down for described revolving part, and move to projection inner terminal position, revolving part coordinates with the unidirectional spline of detent; Move to projection outermost end, revolving part and detent are separated.
Further, be arranged with a spring on described projection, one end of spring acts on detent, and the other end and revolving part inner face offset.
Further, described braking surface is provided with the first ratchet, and revolving part end face is provided with the second ratchet matching with the first ratchet; Between described the first ratchet and the second ratchet, be provided with the field of conjugate action and the sliding surface that cooperatively interact.
Described the first ratchet has convex cone face, and described the second ratchet has the concave cone face matching with convex cone face.
Further, on described projection outer wall, be provided with near detent place the boss offseting with described spring.
In sum, the utlity model has following advantage: this guide post is simple in structure, parts are few, operate steadily and do not rock, not fragile, long service life.

Fig. 2 is the structural representation of detent of the present utility model.
Fig. 3 is the structural representation of revolving part of the present utility model.
Detailed description of the invention
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.
As Figure 1-3, a kind of guide post for mop rod, comprise the body of rod 1, the revolving part 3 that can rotate in inwall has the housing of spiral grooves, be positioned at the detent 2 of the body of rod 1 one ends, detent 2 comprises the braking surface that can coordinate with revolving part 3 splines and the projection 21 that can move up and down for described revolving part 3, concrete, projection 21 is located at the front end of braking surface, sheathed described revolving part 3 on projection 21; In the present embodiment, revolving part 3 outer walls have the spiral bead 34 matching with spiral grooves, and in other embodiment, revolving part outer wall has the protuberance matching with spiral grooves, and this protuberance is spherical structure; Revolving part is sheathed on after projection, and its end is provided with a resistance part 6, for preventing that revolving part from departing from projection; Revolving part 3 can move up and down on projection, and moves to projection inner terminal position, and revolving part 3 coordinates with detent 2 splines; Move to projection outermost end, revolving part 3 is separated with detent, and revolving part rotates on projection.This guide post can be socketed with the outer body of rod of another part of mop rod, guide post lower end connects mophead, upper end and the socket of the outer body of rod, outer body of rod inwall is provided with spiral grooves, and mophead is placed in mop basket, presses the outer body of rod downwards, revolving part rotates along spiral grooves, and detent 2 in guide post is meshed with revolving part, forms spline and coordinate, so revolving part drives guide post to rotate together with mophead; Also this guide post and the outer body of rod can be inverted, guide post is upper, and the outer body of rod is connected with mophead; The utility model adopts detent to be directly connected with guide post, has saved the parts such as lead of the prior art, axle core, the body of rod, directly guide post is connected with detent, has reduced parts, has saved cost; And guide post can directly coordinate with the outer body of rod, has reduced the spacing between outer body of rod inwall, and the process that moves up and down is more stable; Projection is set in detent, revolving part is directly set on this projection, revolving part, detent and projection all adopt identical material, in the time that revolving part dallies in the body of rod outside, and the frictional force between projection reduces, the wearing and tearing of revolving part inwall and projection outer wall also reduce a lot, have extended service life; Projection and detent are integrated injection structure, and running is stable, can not produce and rock, and have also reduced the probability damaging.
In the time upwards elongating mop rod, revolving part and detent depart from mutually, in order to make can to separate fast and continue maintenance released state between revolving part and detent, reduce resistance, so can be arranged with a spring 4 on described projection 21, one end of spring 4 acts on the outer wall of projection, and the other end and revolving part 3 ends offset.Concrete, on described projection 21 outer walls, be provided with near detent place the boss 211 offseting with described spring 4.
Concrete again, the braking surface of described detent 2 and revolving part contact position are provided with the first ratchet 22, and revolving part 3 end faces are provided with the second ratchet 32 matching with the first ratchet 22; Between described the first ratchet 22 and the second ratchet 32, be provided with the field of conjugate action and the sliding surface that cooperatively interact.Further, it is more smooth and easy when detent is coordinated with revolving part spline, described the first ratchet 22 has convex cone face 221, described the second ratchet 32 has the concave cone face 322 matching with convex cone face 221, concavo-convex cone match, engagement, depart from all very quick, especially in the time that both depart from, there is each other friction, the fit system of the concavo-convex conical surface can reduce this friction, increases the service life.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
