Abstract

The utility model relates to a structure of hoister, which is composed of a body, a transmission rod, a roll collection wheel, a shaft sleeve, an outer cover, a crank handle, etc., and is used for rolling up or releasing the rope which is winding arranged in the roll collection wheel. The utility model is characterized in that a shaft sleeve is sleeve arranged between the outer cover and the roll collection wheel; the circumferences of the shaft sleeve are provided with an inclined hole and a shaft end detent on the transmission rod to control the advance and retreat of the shaft sleeve; two ends of the circumferences of the shaft sleeve are provided with corresponding and opposite segmental orifices supplied pivot combined elastic elements and triangle clamp blocks which are respectively in mesh with the roll collection wheel and a ratchet in the concave ring of the outer cover, and a structure of hoister which can prevent reverse when the rotation is stopped is formed.

Description

Structure of hoister

The utility model refers in particular to a kind of hoist innovation structure that has easy structure and have two-way check relevant for a kind of structure of hoist.

Hoist has the occasion of many application at our life periphery, as furl awning etc. and be, and these hoists are with the difference and the requirement of application scenario, multi-form hoist is just arranged for using, as driving the hoist of big gear wheel transmission with miniature gears, or with the hoist of worm and gear mode; Common a kind of hoist is by body, driving gear, furl primary members such as gear and wind and form; Utilize wind to drive driving gear and rotate, and make and furl the gear rotation, do furling to draw and putting of working substance such as awning to furl rope.

But shown in its structure, this kind is existing still to have many shortcomings with hoist, as:

1, must be with the drive of driving gear etc., then whole component part is comparatively numerous and diverse, so, no matter is that material cost or artificial manufacturing cost all can increase relatively, has just reduced competitiveness virtually.

2, the assembly of formation is many, then relatively under, its fault rate of backward using also can increase, in such cases, often allow not yet done repairing technology the customer or use operating personal to increase many meaningless worries.

Edge is that the creator adheres to the rich experiences of this professional manufacturing development for many years, is concentrated on studies at the hoist that this kind commonly used now, provides a kind of hoist new construction of innovation, to improve its disappearance; For the technological means that makes the utility model use and creation purpose are easy to understand, cooperate graphic now and figure number is described in detail as follows:

Fig. 1: the block diagram of the utility model

Fig. 2: illustration is implemented in the combination of the utility model

Fig. 3: the part lateral plan of the utility model

Fig. 4: the shaft sleeve part of the utility model is divided the combination scheme drawing

Fig. 5: the shaft sleeve part of the utility model is divided the combination scheme drawing

At first, see also shown in the three-dimensional exploded view of Fig. 1 the utility model, the utility model by body 2, drive link 3, furl main elements combinations such as wheel 4, axle sleeve 5, enclosing cover 6 and wind 7 and cause.

Body 2 is a suitable set body, leaves corresponding pin joint hole 21,22, and one of therein pin joint hole 22 sides are extended with lug 23 and assembly opening 24; And pin joint hole 21 end faces of opposite side are provided with many screws 25.

But drive link 3 fitted bearings 31 are inserted in the pin joint hole 21,22 and are established for 2 groups with body, and appropriate location is installed with a shaft tip 32.

Intervolve wheel 4 profiles and slightly be H font body, be provided with endoporus 41 and set firmly for drive link 3 insertions; Wherein an end face is provided with scrobicular ring 42, this scrobicular ring 42 be provided with many equidistant within ratchet 43.

Axle sleeve 5 is a ducted body, can be inserted in drive link 3, and periphery is provided with relative inclined hole 51 and can matches with the shaft tip 32 of drive link 3; These axle sleeve 5 flanges are provided with and manyly ［ see also shown in Fig. 4～5 ］ with furling wheel 4 scrobicular ring 42 corresponding scarce holes 52 in addition, and this scarce hole 52 just can be for being pivoted of triangle fixture block 53 and elastic element 54, and it is corresponding to be both ends of the surface.

Enclosing cover 6 has bearing hole 61 for placement bearing 62, and end face also is provided with scrobicular ring 63 and interior ratchet 64, and direction of ratchet 64 is just opposite with the interior ratchet 43 that furls wheel 4 in this; And enclosing cover 6 just can be inserted in the pin joint hole 21 of body 2 and utilize screw and screw 25 to make it group and establish fixing.

After forming by said elements, furl that wheel 4 sets firmly with drive link 3 and pivot closes in body 2, axle sleeve 5 and furling between wheel 4 and the enclosing cover 6, wind 7 then is fixedly arranged on the tail end of drive link 3; When wind 7 clockwise rotates; furl wheel 4 and axle sleeve 5 protections one appropriate gap; and axle sleeve 5 and enclosing cover 6 end faces are for suitably to contact; and triangle fixture block 53 and interior ratchet 64 are for forward contacting ［ as shown in Figure 4 ］; so when clockwise rotating; furl wheel 4 and rotate when furling rope 8 together with axle sleeve 5, triangle fixture block 53 can lack in the hole 52 because of enclosing cover 6 motionless sinking to, and makes that to furl action smooth.

When stopping operating wind 7, furling wheel 4 can be because of the desire counter-rotating of pulling back of rope 8, but axle sleeve 5 pushes against in the interior ratchet 64 of enclosing cover 6 because of triangle fixture block 53, and furls wheel 5 multiple triangle fixture blocks 53 because of axle sleeve 5 opposite sides and snap in the handle ratchet wheel 43 and also can't turn round; Promptly be in ［ as shown in Figure 4 ］ in the actionless state.

Please consult shown in Figure 5ly more in the lump, desire counter-rotating furls wheel 4 o'clock, when wind 7 is rotated counterclockwise, then the shaft tip 32 in the inclined hole 51 can utilize the effect of screw inclined plane, and axle sleeve 5 is pressed to the left side, and axle sleeve 5 and enclosing cover 6 end faces are separated fully, by this, can will furl wheel 4 counter-rotatings to decontrol rope 8; When letting go again, the strength of pulling back of rope 8, make again the triangle fixture block 53 of axle sleeve 5 both sides embed once more in the

ratchet

43,64, make to furl wheel 4 and keep motionless again, become a kind of can two-wayly the rotation, but can prevent the structural improvement of the hoist that reverses when static again.

Via the composition of said elements, the structural improvement of the utility model hoist has following advantage, as:

1, structure and commonly use ware and compare, the quite good and design simplified of tool, whole manufacturing cost is comparatively cheap, and its competitive power on market is greatly improved.

2, mentioning in the same breath is forward and reverse operation, stops the rotation of wind at any time, and the both sides triangle fixture block on the axle sleeve is brought into play the function of two-way check immediately, makes to furl to take turns to be able to transfixion, prevents the function of rotating again.

Claims

A kind of structure of hoist is by body, drive link, furl wheel, axle sleeve, enclosing cover and wind and be formed by combining; To furl wheel and place in the body and set firmly, and install axle sleeve and enclosing cover in regular turn, and utilize wind to drive drive link at last and furl wheel and rotate, to furl or to decontrol the rope of winding in furling wheel with power wheel; It is characterized in that: at enclosing cover and furl and be arranged with an axle sleeve between wheel, this axle sleeve periphery has an inclined hole to engage with shaft tip on the drive link with actuating spindle cover advance and retreat, and these axle sleeve periphery both ends of the surface are provided with corresponding and otherwise elastic element and triangle fixture block are closed for pivot in the mutually scarce hole of direction, and be meshed with ratchet in the scrobicular ring that furls wheel and enclosing cover respectively, the hoist that can prevent reverse when stopping operating is provided.
