Abstract
The utility model relates to a hinge device, in particular to a ratchet type hinge device which comprises a first shell, a second shell, a mounting shaft for hinging the two shells, and a ratchet fixedly arranged on the mounting shaft, wherein the first shell is connected with the mounting shaft in a rotatable manner; the mounting shaft is fixedly connected to the second shell; a wrench and a check pawl are arranged on the first shell; one end of the wrench push against one end of the check pawl; and the other end of the check pawl is elastically meshed with the tooth back of the ratchet. The ratchet type hinge device has the beneficial effects that since the ratchet is meshed with the check pawl, a hinge can be adjusted; meanwhile, due to the arrangement of the wrench, a user can conveniently apply force to the hinge device so as to quickly and effectively adjust the hinge device, so that the flexibility of the hinge is realized; moreover, shell-type connection is adopted, so that the problem of stressed deformation of the conventional hinge, caused by adoption of a thin chain plate, is solved; and therefore, the strength is improved greatly.
Description
Technical field
The utility model relates to hinge means, particularly a kind of ratchet-type hinge means.
Background technique
Hinge sees often that in daily life it is the important tool that connects each parts, in the ladder field; Conventional trestle ladder adopts linkage mechanism to reach packing up of ladder and opens, and its hinge means adopts two blocks of carrier bars and bolted splice to form usually, and the deficiency of this design has been to limit the opening angle of trestle ladder; In addition, common hinge is not enough on intensity usually; Be fixed on the hinge on two links with rivet, because heavy factor, carrier bar can produce distortion; Serious rivet also can come off, thereby possibly cause security incident.
The model utility content
The technical problem that the utility model will solve is: a kind of ratchet-type hinge means is provided, and it is low to solve existing hinge means intensity, the technical problem of controllability, Security, very flexible.
The utility model solves the technological scheme that its technical problem adopted: a kind of ratchet-type hinge means; Comprise first housing, second housing, be used for the installation shaft of hinged two housings and be fixedly mounted on the ratchet on the installation shaft; First housing and installation shaft are rotationally connected, and are fixedly connected with installation shaft on second housing, and said first housing is provided with spanner and check pawl; Said spanner one end roof pressure check pawl one end, the check pawl the other end and ratchet back of tooth Elastic Meshing.
In order to make the hinge means can free adjustment and firm, all be set with torque spring on said spanner and the check pawl, check pawl one side is provided with bumping post.
The beneficial effect of the utility model is that the ratchet-type hinge means of the utility model is through the engagement of ratchet and check pawl; Guaranteed the can regulate of hinge, being provided with of spanner made things convenient for putting forth effort of staff simultaneously, can regulate hinge means fast and effectively; So just realize the flexibility of hinge, in addition, adopted the link of shell type; Prevented therefore on intensity, to improve a lot again because of the problem of the thin stress deformation that produces of carrier bar of conventional hinge.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the ratchet-type hinge means specific embodiment of the utility model.
Among the figure: 1. first housing, 2. ratchet, 3. installation shaft, 4. second housing, 5. check pawl, 6. torque spring, 7. spanner, 8. bumping post.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The structural representation of ratchet-type hinge means specific embodiment as shown in Figure 1; Comprise first housing 1, second housing 4, be used for the installation shaft 3 of hinged two housings and be fixedly mounted on the ratchet 2 on the installation shaft 3; First housing 1 is rotationally connected with installation shaft 3, is fixedly connected with installation shaft 3, the first housings 1 on second housing 4 and is provided with spanner 7 and check pawl 5; Spanner 7 one end roof pressure check pawls 5 one ends; Check pawl 5 the other ends and ratchet 2 back of tooth Elastic Meshing all are set with torque spring 6 on spanner 7 and the check pawl 5, and check pawl 5 one sides are provided with bumping post 8.
When needs closure hinge, so only need two housings be drawn close, when angle is suitable; Check pawl 5 can withstand the back of tooth of ratchet 2; And check pawl 5 is because the effect of bumping post 8, stoped self rotation of check pawl 5, so just can prevent that hinge is stressed to open; When needs open hinge, only need to press lower ejector lever 7, because spanner 7 one end roof pressures are at an end of check pawl 5; Check pawl 5 receives to compel to rotate, and no longer with ratchet 2 engagements, ratchet 2 is with unrestricted free to rotate; At this moment can arbitrarily adjust opening angle, after adjusting angle, unclamp spanner 7; Because the effect of torque spring 6, check pawl 7 is got back to original position once more, meshes with ratchet 2 back of tooth; Just can easily hinge means be adjusted various angles and fix through such design, to adapt to various job requirements.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
