Abstract

The invention discloses a folding crawler type mop, which is characterized in that: on each side of the connected rollers, an inner side plate and an outer side plate are connected by a pin, so that a rectangular frame formed by connecting the side plates to the shafts of the rollers by using screws can be folded in half; one of the two rollers is bidirectional, and the other roller is unidirectional; and both rollers are formed by combining half rollers by gluing and pinning. The difference between the two rollers lies in that the inner side wall of a half-roller pin opening of the unidirectional roller is fixed by a screw with an elastic pawl which is matched with a ratchet on a ratchet shaft. The thicknesses of all the connected parts are reduced by a half to make the connected inner side plates and outer side plates in straight lines; a ring-shaped mop can be accurately and easily sleeved on the rollers in a folding state; vertical folding edges are pressed down to tighten the mop; inner side plate through holes are superposed with outer side plate through holes close to the pins when the side plates are in the straightening state; short shafts, of which the inner sides of the bar-connecting bottom fork ends are matched with the through holes, are inserted into the through holes to complete the assembly; and the mop can be disassembled by a reverse process. The mop can mop a large area at one time, save labor and water and mop carpets.

Description

Foldable crawler type mop

Technical field

The present invention relates to the cleaning appliance of living, specifically a kind of foldable crawler type mop.

Background technology

The inventor has formerly invented the utility model patent twin-roll crawler type mop that a kind of notification number is CN 2678553Y.This mop working head has two cylinders, and two drum shafts connect with two side plates, and cylinder one side is provided with a unilateral bearing therein, and unilateral bearing axis hole and drum shaft fixedly outer ring are then fixed with cylinder.Be provided with axis hole in the biside plate stage casing, the minor axis that the inboard, chain stay end that this axis hole links to each other with mop rod sets firmly is complementary, and axial length is also suitable with side plate thickness.So when two bottom fork axis inserted above-mentioned hole, the rectangle frame of being made up of two cylinders and side plate can freely overturn in chain stay.When mop, when push-and-pull, a direction rolling set-off (the mop fiber opens at the cylinder place, among closed adhesion booty is in fiber thereafter) is always arranged under centrifugation effect; Do not change then at another direction cylinder and to wipe ground.Because the continuous rotation of double-deck mop, so clean the area multiplication that once mops floor; Because of all level dyeing is dirty, water-saving result is obvious again.The more important thing is to be used to the blanket that mops floor, push away roll mode before only using, using during preceding pushing away rolls adheres to booty, after drag then and wipe clearly, obtain good cleaning effect.But there is a problem that is difficult to solution in this utility model patent.Though chain stay can conveniently take off, but cylindric mop is difficult to put, because mop is loaded onto certain force of strain will be arranged as required, then cylinder mop girth outline is shorter than the girth that comprises two cylinders, moreover to prevent that also mop skids in use between cylinder, cylinder surface is crude.If the mop cylinder is cut apart with a knife or scissors the employing slide fastener, then not only slide fastener can skid with ground and also can cause timber floor to scratch, and the head of slide fastener also can't be handled in addition, and since mop be shorter than overlap the position, zip up is also very difficult; Velcro overlaps or connects also because the unequal problem of thickness and hardness also can not be used with hook.The process for integrally manufacturing of cylinder is difficult in addition realizes, and the position of unilateral bearing comprises and has problems in being assemblied in.

Summary of the invention

In view of there is above-mentioned defective in prior art, technical problem to be solved by this invention is to use, and reasonable, simple and reliable structure realizes the problem that the cylindric mop of uniformity is conveniently installed and taken off.This scheme is established two cylinders, and one is that unidirectional rotation one is two-way rotation, and two cylinders adopt half barrel structure gluing pin to close and form integral body; Before pin closes, close at half pin of unidirectional cylinder on the inwall of end and be provided with elastic pawl, ratchet and above-mentioned elastic pawl on this cylinder ratchet shaft are complementary, to reach the function of unidirectional cylinder.The bilateral side plate that is connected on two cylinders by nut is respectively connected by bearing pin by interior outer panel, but so rectangle frame doubling of forming by cylinder and side plate, thereby realize the mop circle can accurately be enclosed within rapidly between the both sides side that erects cylinder on, depress flanging, then the mop circle is tightened; It is opposite to take off the mop mode.For outer panel side direction center in making on same straight line, each side plate position that is harmonious all is made as half of thickness.Under the stretching state of side plate, near the bearing pin of bilateral side plate middle part applying position symmetry establish one fixing in the through hole of outer side edges, this through hole also is and the connecting portion of mop rod, is complementary with the terminal inboard minor axis of the chain stay of mop rod one, supply its sell into.

The specific embodiment

Referring to Fig. 1 and Fig. 2, this mop mainly is made up of mop 1, chain stay barre 2, unidirectional cylinder 3, bidirectional roller 11, outer panel 8 and interior plate 6.

Referring to Fig. 3 and Fig. 4, remove chain stay barre 2 after, but the rectangle frame doubling that outer panel 8 and interior plate 6, unidirectional cylinder 3 and bidirectional roller 11 are formed is convenient to load onto and pull down mop like this and is cleaned.

Referring to Fig. 2, Fig. 5 and Fig. 6, the assembly of unidirectional cylinder is by ratchet shaft 4, elastic pawl 15, and screw 12, half cylinder 3-1 and 3-2 form.Elastic pawl 15 is connected on the half cylinder 3-1 by screw 12, and elastic pawl 15 fits with the ratchet 4-1 that is welded on the ratchet shaft 4, thereby bonding can only be around ratchet shaft 4 unidirectional rotations to cylinder 3.Half cylinder 3-1 is coated with the glue pin joint with 3-2 and becomes whole unidirectional cylinder 3, and the axis hole 3-1a and the 3-2a of unidirectional cylinder 3 both sides passed at ratchet shaft 4 two, is fixed on drum shaft 4 two ends with thin nut 5 by interior plate 6;

Referring to Fig. 2 and Fig. 7, the assembly of bidirectional roller mainly is made up of drum shaft 10, half cylinder 11-1 and 11-2, and is the same with unidirectional cylinder 3, and it is whole that half cylinder 11-1 becomes with 11-2 gluing pin joint, and the two axis hole 10-1 that are enclosed within drum shaft 10 go up and can rotate freely; Drum shaft 10 passes both sides axis hole 11-1a and 11-2a, is fixed on the drum shaft 10 by outer panel 8 with thin nut 9;

Referring to Fig. 2, Fig. 3 and Fig. 4, outer panel 8 and interior plate 6, connect by bearing pin 7, the axial float of bearing pin 7 limits with pad 13 and bending pin 14, and outer panel 8 and interior plate 6 can rotate around pivot pin 7, when outer panel 8 and interior plate 6 are stretching, through hole 8-2 under the guide groove 8-1 of outer panel 8 overlaps with through hole 6-1 on the interior plate 6, draw back chain stay slightly slightly and press down this moment, and pivot pin 2-1 then slips under guide groove 8-1 in two through hole 8-2, thereby keep outer panel 8 and interior plate 6 to be in stretching state.In order to make outer panel 8 and interior plate 6 in same plane, the thickness at all applying positions all is kept to half of original thickness.
