Abstract
The invention relates to a straight horse ladder with triple-purpose joints. The straight horse ladder comprises first ladder frames, second ladder frames and joint mechanisms, wherein the first ladder frames and the second ladder frames are hinged by the joint mechanisms; each joint mechanism comprises a first shell, a second shell, a mounting shaft for hinging the first shell and the second shell, and a ratchet wheel fixedly arranged on the mounting shaft; the first shell is rotatably connected with the mounting shaft; the mounting shaft is fixedly connected to the second shell; and a wrench and a non-return pawl are arranged on the first shell, wherein one end of the wrench supports against one end of the non-return pawl, and the other end of the non-return pawl is elastically engaged with the tooth back of the ratchet wheel. According to the straight horse ladder, a light-reflecting caution zone which is coated on each ladder upright plays a caution role; meanwhile, a rubber sleeve which is sleeved on each ladder leg and knurling patterns on pedals can play an anti-skidding role; in addition, a ratchet wheel type articulation device can ensure that the stretching angle of the straight horse ladder can be freely adjusted; and the straight horse ladder disclosed by the invention is suitable for various working demands and convenient and rapid to operate.
Description
Technical field
The present invention relates to the ladder technical field, particularly the straight horse ladder of a kind of joint three usefulness.
Background technology
In daily life, straight horse ladder is maintenance personal's indispensable instrument when the maintenance power equipment, and whether straight horse ladder light safety, whether anti-skidding, be easy to carry about with one, all can bring impact to maintenance, at present, that generally uses has a double ladder, and this kind ladder feet opening angle is limited, be not suitable for various occasions, and there is the single problem of working method in the other generally single straight ladder of usefulness, in some complicated occasions, can not have at any time polytropy, underaction.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of joint three usefulness straight horse ladder, the existing ladder of solution does not possess changeable, the technical problem of underaction.
The technical solution adopted for the present invention to solve the technical problems is: the straight horse ladder of a kind of joint three usefulness, comprise the first ladder, the second ladder and articulation mechanism, the first ladder and the second ladder are hinged through articulation mechanism, described articulation mechanism comprises the first housing, the second housing, the installation shaft and the ratchet that is fixedly mounted on the installation shaft that are used for hinged two housings, the first housing and installation shaft are rotationally connected, be fixedly connected with installation shaft on the second housing, be provided with spanner and check pawl on described the first housing, check pawl one end, the check pawl other end and ratchet back of tooth Elastic Meshing are pressed in described spanner one end top.
In order to make straight horse ladder be convenient to regulate various duties, torque spring all is installed on described spanner and the check pawl, check pawl one side is provided with a grade post.
In order to make straight horse ladder that caution and anti-skidding effect be arranged, described the first ladder and the second ladder comprise ladder side and mark time, and scribble the reflection alarming band on the described ladder side, and the rubber antiskid cover is installed on the foot of ladder, have the annular knurl striped on described the marking time.
The invention has the beneficial effects as follows, the straight horse ladder of joint of the present invention three usefulness, by scribble the reflection alarming band in ladder side, play warning function, simultaneously, annular knurl striped on all overlapping rubber sleeve on the foot of ladder and marking time, play anti-skidding effect, the other articulated mounting of ratchet-type is so that straight horse ladder can freely be adjusted opening angle, be convenient to be fit to various job requirements, convenient and swift.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the straight horse ladder of joint three usefulness of the present invention body embodiment;
Fig. 2 is the sectional view of the articulation mechanism of the straight horse ladder of joint three usefulness of the present invention;
Fig. 3 is three kinds of working state schematic representations of the straight horse ladder of joint three usefulness of the present invention.
Among the figure: 1. the first ladder, 2. articulation mechanism, 21. first housings, 22. ratchets, 23. installation shaft, 24. the second housing, 25. check pawls, 26. torque springs, 27. spanners, 28. bumping posts, 3. the second ladder, 4. reflection alarming band, 5. rubber antiskid cover, 6. ladder side is 7. marked time.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The specific embodiment of the straight horse ladder of joint of the present invention three usefulness shown in Fig. 1～3, comprise the first ladder 1, the second ladder 3 and articulation mechanism 2, the first ladder 1 and the second ladder 3 are hinged through articulation mechanism 2, articulation mechanism 2 comprises the first housing 21, the second housing 24, the installation shaft 23 and the ratchet 22 that is fixedly mounted on the installation shaft 23 that are used for hinged two housings, the first housing 21 is rotationally connected with installation shaft 23, be fixedly connected with installation shaft 23 on the second housing 24, so just so that the second housing 24 and ratchet 22 coaxial rotation, be provided with spanner 27 and check pawl 25 on the first housing 21, in order to be fit to various working environments, but free adjustment opening angle, check pawl 25 1 ends are pressed on spanner 27 1 ends top, check pawl 25 other ends and ratchet 22 back of tooth Elastic Meshing, on spanner 27 and the check pawl 25 torque spring 26 is installed all, check pawl 25 1 sides are provided with bumping post 28; The first ladder 1 and the second ladder 3 comprise ladder side 6 and mark time 7, scribble reflection alarming band 4 on the ladder side 6, so just can be in the place of insufficient light when especially keep in repair power equipment night, can play warning function to pedestrian or vehicle, rubber antiskid cover 5 is installed on the foot of ladder in addition, can be so that ladder fixing, marking time has the annular knurl striped on 7, and such design can be fit to the rainy day condition, because the effect of annular knurl striped, increased frictional force, so be difficult for slipping phenomenon.
When the staff needs closed ladder, so only two ladders need to be drawn close folding, when angle is suitable, check pawl 25 can withstand the back of tooth of ratchet 22, and check pawl 25 is because the effect of bumping post 28, stoped self rotation of check pawl 25, so just can prevent from that ladder is stressed to open; When needs open ladder, only need press simultaneously the spanner 27 of both sides articulation mechanism 2, because spanner 27 1 ends top is pressed in an end of check pawl 25, check pawl 25 is forced to rotate, no longer with ratchet 22 engagements, ratchet 22 is with unrestricted free to rotate, at this moment can arbitrarily adjust opening angle, after adjusting angle, unclamp spanner 27, because the effect of torque spring 26, check pawl 25 is got back to original position again, with ratchet 22 back of tooth engagements, by such design just can be easily with the whole various angles of straight horse trapeziodal modulation and fixed, to adapt to various job requirements.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the manual, must determine its technical scope according to the claim scope.
