The intermeshing of gear, drives casing to realize elevating function, but also there is tooth in the existing lowering or hoisting gear for using
Bar is easily slipped with gear, the problem of stability difference, have impact on the using effect of lowering or hoisting gear;Also, rising
During drop, the lifting track inconvenience of casing, it is difficult to which the part outside to track is operated.
It is those skilled in that art urgently to be resolved hurrily therefore, because there is above-mentioned technological deficiency in the prior art
Technical problem.
The content of the invention
The purpose of the present invention is a kind of rack-and-pinion lowering or hoisting gear of offer, it is intended to solve tooth present in prior art
It is poor that bar engages effect with gear, easily comes off, and track fixed effect using effect problem.
To achieve the above object, the present invention provides following technical scheme:
A kind of rack-and-pinion lowering or hoisting gear, including the first articulated elements, the second articulated elements, support member, strip are logical
Hole, tooth bar, gear, fixture, connecting rod, sliding block, casing and push rod, the support member is by the first hinge
Fitting connects ground, and the push rod connects ground by the second articulated elements, and the support member middle part radially sets
There is strip through hole, the support member sidepiece is provided with tooth bar, and the push rod sidepiece is provided with casing, the case-side
Portion is provided with fixture, and the fixture is provided with gear, and the gear is meshed with the tooth bar, the gear
Rotating shaft connection connecting rod one end, the connecting rod other end connection sliding block, the sliding block is in the strip through hole
Interior slip.
Preferably, the push rod is expansion link.
Preferably, also including cushion pad, the cushion pad is located at the casing bottom.
The present invention is advantageous in that:By the lowering or hoisting gear to existing rack pinion cooperation in the prior art
Transformed, make the engagement of wheel and rack even closer, anti-dropout effect is good;Also, push rod is set to
Telescopic form, extends range of application.Simple structure of the present invention, easy to use, rack and pinion engagement
Effect is good, effective anti-dropout, job enlargement.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, in describing below
Accompanying drawing is only some embodiments of the present invention, for those of ordinary skill in the art, is not paying creation
Property work on the premise of, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the invention;
In figure:1 first articulated elements;2 second articulated elements;3 support members;4 strip through holes;5 tooth bars;6
Gear;7 fixtures;8 connecting rods;9 sliding blocks;10 casings;11 push rods;12 cushion pads.
Specific embodiment
The invention provides a kind of rack-and-pinion lowering or hoisting gear, simple structure of the present invention is easy to use, tooth bar with
Gear engagement effect is good, effective anti-dropout, job enlargement.
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out it is clear and
Detailed description, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole
Embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not before creative work is made
The all other embodiment for being obtained is put, the scope of protection of the invention is belonged to.
A kind of rack-and-pinion lowering or hoisting gear as shown in Figure 1, including the first articulated elements 1, the second articulated elements 2,
Support member 3, strip through hole 4, tooth bar 5, gear 6, fixture 7, connecting rod 8, sliding block 9, casing
10 and push rod 11, the support member 3 connects ground by the first articulated elements 1, and the push rod 11 passes through second
Articulated elements 2 connects ground, and the middle part of the support member 3 is radially provided with strip through hole 4, the support member
3 sidepieces are provided with tooth bar 5, and the sidepiece of the push rod 11 is provided with casing 10, and the sidepiece of the casing 10 is provided with fixture
7, the fixture 7 is provided with gear 6, and the gear 6 is meshed with the tooth bar 5, the gear 6
Rotating shaft connection connecting rod 8 one end, the other end connection sliding block 9 of the connecting rod 8, the sliding block 9 is in the length
Slided in strip through-hole 4.
Further, the push rod 11 is expansion link.The setting of expansion link, can be in tooth bar 5 and gear
During 6 intermeshing liftings, by the telescopic action of push rod 11, casing 10 is set to arrive any position with activity
Put, improve it and use scope.
Further, also including cushion pad 12, the cushion pad 12 is located at the bottom of the casing 10.It is slow
