Abstract

The invention discloses a shoelace screwing device. A shoelace is wound at the periphery of a hollow column arranged in an upper cover of the device, is fastened by rotating a knob clockwise and is loosened by rotating the knob anticlockwise; the joint and separation of an occlusion button and a one-way gear is used for controlling the fixation and free rotation of the upper cover; and a left baffle body and a right baffle body are matched to jointly limit the rotation angle of the occlusion button. The shoelace screwing device has the advantages of eliminating the trouble of tying the conventional shoelace by crossing and making a knot, quickly and conveniently tying the shoelace and ensuring that the shoelace cannot be loosened when fastened.

Description

The shoestring device of screwing

Technical field

The present invention relates to a kind of shoestring device of screwing, specifically is a kind of quick locking shoestring or the shoestring that the loosens shoestring device of screwing.

Background technology

Tie the shoelace all the time and all adopt the mode of shoestring intersection knotting, it is very inconvenient to waste time and energy, and occurs the situation that shoestring unclamps easily, if be in the situation of sports, very likely causes athletic falling; If shoestring unclamps and then can influence the control of driver to throttle and brake pedal when driving, and child old man's also inconvenience of tying the shoelace.

In order to address this problem; For example Chinese utility model patent 92233392.0 has adopted by swivelling cover and has been fixed on the base; The swivelling cover inwall is provided with stop tooth; Be provided with the scheme (being the Shoestring tying device that belongs to a kind of internally-fixed) that spring and snap-in pin fix stop tooth in the chamber that forms between swivelling cover and the base,, should hold the shoestring of certain-length in the limited chamber that between swivelling cover and base, forms though shoestring can fastened and unclamp to this device; Engaging device breaks away from these functions of swivelling cover when fixing swivelling cover when realizing fastening shoestring again and unclamping shoestring; Therefore just caused several internally-fixed shoestrings that comprised in the disclosed Chinese patent general shortcoming that has of device of screwing: 1. complex structure, part are of a great variety, have improved manufacture difficulty and cost, have reduced reliability; 2. shoestring produces with numerous parts of chamber interior easily and interferes even stuck, has influenced smooth and easy when operating; 3. body is long-pending huge, weight increases to cause shoestring to be screwed, and has influenced the snugness of fit attractive in appearance of shoes.

In addition; China's utility model patent 03226037.7 adopts base is fixed on the scheme on the flap; This scheme not only has aforesaid shortcoming; And the base of hard has been installed on the original soft flap, and can make the wearer produce foreign body sensation, it can not directly be installed and used on existing conventional shoe influence the wearing comfortableness while.

Summary of the invention technical problem to be solved by this invention is: intersect loaded down with trivial details and inconvenient that the knotting mode ties the shoelace to traditional shoestring; A kind of outer shoestring fixed, that can lock or loosen shoestring fast device of screwing is provided, and be simple in structure, volume light and handy, reliable in action, comfortable easy-to-use.

In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is: the open tubular column of loam cake entangles the interior pillar of base and fixes with screw in case deviate from, and loam cake can be done 360 ° of rotations with respect to base; The loam cake madial wall entangles the chassis outer side wall simultaneously, makes a circle in loam cake week and is provided with ratchet, and the top is provided with knob; Be provided with screw hole in the middle of the knob, loam cake inside is provided with open tubular column, and the lower end of open tubular column is provided with symmetrical two semicircular ring; The both sides of base respectively have a circular hole to penetrate for shoestring; The center of base has a top to be provided with the interior pillar of screw hole, and base is provided with ennation, is fixed with latch, interlock knob, left block body, right block body on the ennation successively; There is a circular hole that latch is penetrated on the interlock knob; The latch lower end is fixed on the base, left block body one steady pin is arranged so that spring housing on steady pin, left block body cooperates the common rotational angle that limits the interlock knob with right shelves body.

Two shoestrings on the shoes pass circular hole respectively and also fasten on semicircular ring on

top.

Except that spring, latch, screw, other part is the duroplasts material.

The invention has the beneficial effects as follows: only need rotary upper cover just can loosen, tighten shoestring easily, and fasten the back shoestring and can not unclamp.And existing conventional shoe need not to change this Shoestring tying device just can be installed.

The specific embodiment

As shown in Figure 2, the shoestring device of screwing is positioned at vamp top, and two shoestrings penetrate from the circular hole of base respectively.In Fig. 1; Loam cake and base combine; The top of loam cake is provided with knob, and the top of knob offers circular hole, and making a circle outward is ratchet; The sidewall of base has two corresponding circular holes, on the ennation of base, is provided with to stop the rotating assembly of loam cake: interlock knob, left block body, right block body, latch, spring, steady pin.

With reference to Fig. 3,4,5,6; Loam cake inside is provided with open tubular column; Its internal diameter is slightly larger than the external diameter of pillar in the base, and the lower end of open tubular column has symmetrical two semicircular ring to supply two shoestrings that penetrate to fasten respectively, and the internal diameter of the madial wall of loam cake is slightly larger than the external diameter of the lateral wall of base.

With reference to Fig. 7,8,9,10, the center of base is provided with the interior pillar that a top offers screw hole, and its effect is: make on the pillar in the open tubular column of loam cake is enclosed within that loam cake can be around the base rotation 1.; 2. screw passes circular hole that the knob of loam cake offers and can prevent that loam cake from separating with base on the pillar in being locked in.

Be fixed with left block body, right block body and latch on the ennation of base; The circle hole sleeve of interlock knob is on latch and can rotate; Left side block body is provided with a steady pin, and spring one end is fixed on the side that the other end on the steady pin withstands the interlock knob, and their acting in conjunction is the rotational angle of control interlock knob; Interlock knob block body one side rotation left during promptly with the finger application of force, the interlock knob then was close on the right block body when nothing applied external force.

Shoestring passes in the chamber that forms between circular hole entering loam cake and the base respectively and fastens on the semicircular ring of open tubular column; When the user with one hold ennation another hand pinch knob when clockwise rotating loam cake shoestring tightly wrap; The interlock knob withstands ratchet and a side automatically because of the effect of spring and is close to and has just stoped loam cake toward revolution counterclockwise on the right block body, and the action of tying the shoelace is accomplished; When unclamping shoestring, the user only need push that the interlock knob makes it and ratchet breaks away from open, and loam cake drew back shoestring again and got final product toward counterclockwise turning round the unrestricted while this moment.
