Description

The vertical universal straining ratchet of hood type

Technical field

The utility model relates to a kind of strainer, the particularly a kind of vertical universal straining ratchet of hood type that wire rods such as steel wire, rope yarn can be strained.

Background technology

In daily life, in order between cylinder, to draw single line material (steel wire or rope yarn), often the method for Cai Yonging is that hook is installed earlier in the above, perhaps stamp wall nail, swell fixture, between hook or wall nail, swell fixture, pull on wire rod then, adopt this method often to exist problem: in the process of backguy, only generally all be difficult to make its tension by manpower, its tensioner degree is not enough, so that its wire rod is sagging serious when hanging article, do not reach its requirement, especially especially obvious in the very big place of span; Even by manpower wire rod has been strained now, in use for some time, elongation strain also can take place in wire rod, and its tensioner degree also can descend, if regulate its tensioner degree by manpower once more, what just show is cumbersome.Recently, for improving above problem, a L type strainer is disclosed, as shown in Figure 1, its structure comprises L type support 101, this L type support 101 wherein the one side on offer a fixing hole 102 at least, on its another side, be equipped with a tie rod 103, the both sides of this tie rod 103 are provided with nut 104 and clamp nut 105 respectively, adopt the strainer after this structure, in use, can by fixing hole 102 L type support 101 be fixed on the cylinder earlier, tie rod 103 on another side passes through fixedly wire rod of clamp nut 105, in the tension wire rod, tie rod 103 is moved axially by the nut 104 on the rotation tie rod 103, thereby the wire rod that is fixed on the clamp nut 105 is also produced to be moved axially, reach the tension effect of wire rod with this, but its tensioner degree adjustable range can be subjected to the certain limitation of tie rod length, the tension distance is limited, simultaneously, because of L type support 101 is fixed on the cylinder, not only can destroy cylinder itself, and the tie rod 103 on two strainers is not in relative position, when there is deviation in angle, can not regulated at will L type support 101, make the wire rod that draws between two strainers can not be at one's best.

Summary of the invention

It is a kind of under the situation of not destroying cylinder itself that the purpose of this utility model is to provide, energy is adjusting angle automatically, and can regulate the tensioner degree of its wire rod at any time and the adjustable range of tensioner degree is not awarded restriction, can be used for the vertical universal straining ratchet of hood type on the vertical cylinder of placing.

In order to reach above-mentioned purpose, solution of the present utility model is:

The vertical universal straining ratchet of a kind of hood type, comprise a circular arc support, L type support, one end of this circular arc support is circular-arc and is connected with circular arc lid on this end, wherein one side by I shape rotating shaft and L type support on the circular arc support flexibly connects, another side at L type support then is equipped with roll, it is axially arranged with a perforation that places for wire rod this roll upper edge, and also on the outer circumference surface of this roll, being installed with a ratchet, the below that is positioned at ratchet is installed with the ratchet that is used with ratchet.

As the further setting of such scheme, described roll is " T " font, and is connected with a diaphragm baffle in the less end of its diameter, also is provided with the first passage that passes for wire rod between the less end of this diaphragm baffle and roll diameter.

Described on roll and the adjacent that is positioned at ratchet be provided with a ring groove, and between ring groove and first passage, be provided with the second channel that passes for wire rod.

Described adjacent at ratchet is fixed with spring leaf by steady pin, and an end of this spring leaf contacts with ratchet.

Described diaphragm baffle is fixedlyed connected by the less end of lock-screw and roll diameter.

Described ratchet is fixedly sleeved on roll by hold-down screw.

After adopting said structure, the utility model is by circular arc support and being connected and fixed on the cylinder of vertical placement that circular arc covers, wire rod can pass the perforation on the roll, and its winding is fastened on the outer surface of roll, ratchet can drive the roll rotation, thereby can make wire rod continue to twine, and then reach the purpose of tension wire rod at roll.In the process that wire rod is tightened up, wire rod is stressed, drives L type support along the rotational automatic adjusting angle of its rotating shaft, makes the roll on the L type support be in relative position, and the wire rod that is drawn is in the optimum state of straight line automatically.After wire rod was tightened up, ratchet just can stop ratchet drive roll to do counter-rotating, and then prevents to unclamp wire rod.

After wire rod is tightened up a period of time, elongation strain may take place in wire rod, the tensioner degree descends, at this moment, rotate, make wire rod continue to twine at roll as long as drive roll by ratchet again, and then strain wire rod once more, reach required tensioner degree, so the tensioner degree of wire rod can regulate at any time by the rotation of roll, and adjustable range is not awarded any restriction.
