Abstract
The utility model discloses a tightener with a ratchet wheel mechanism, the aim of which is to provide a tightener with the advantages of simple structure, convenient use and high work efficiency. The utility model comprises a sleeve barrel with a screw hole, wherein the sleeve barrel is provided with a guy hook which is matched with the screw hole of the sleeve barrel and is provided with a screw rod, and the sleeve barrel is provided with a reversing ratchet wheel mechanism. A ratchet wheel is arranged on the sleeve barrel, and a ratchet pawl is arranged on a handle. The tightener with the ratchet wheel mechanism, which is manufactured according to the scheme, can change the rotary angle of the ratchet pawl according to use requirements, and the handle is pulled so that the sleeve barrel is rapidly rotated to enable the guy hook to be rapidly extended out of the sleeve barrel or to be retracted in the sleeve barrel. The utility model has the advantages of convenience and labor saving, and can be widely applied to operations of tensioning threads of constructions, electric power construction, etc.
Description
Technical field
The utility model relates to anchoring, relates in particular to a kind of turnbuckle.
Background technology
In building, power construction, often need to use static line,, need use turnbuckle in order to make fixing line tension.Turnbuckle commonly used is the sleeve by two end band rotation direction opposite threads holes, the associated guy hook that is threaded bar is housed in the screwed hole of sleeve two ends, work as turnbarrel in use, stretch out outside the sleeve simultaneously or be retracted in the sleeve at the guy hook of its two end, to regulate the length between two guy hooks, when on two guy hooks fixedly during backguy, can play the effect that backguy is strained or loosened, but generally on sleeve, be shaped on hexagon or be welded with handle, rely on spanner or manually come the plate moving sleeve to make its rotation, the distance of regulating guy hook uses inconvenience like this, sometimes also be subjected to spatial constraints, do not use power.
The utility model content
The purpose of this utility model provides a kind of turnbuckle of band ratchet mechanism of simple in structure, easy to use, high efficiency.
In order to achieve the above object, scheme of the present utility model is: comprise the guy hook that the band screw rod that matches with the sleeve screw is housed on sleeve with threaded hole, the sleeve, but the ratchet mechanism of break-in is housed on sleeve.Ratchet is contained on the sleeve, and ratchet is contained on the handle.
The turnbuckle of the band ratchet mechanism of making according to such scheme can change the anglec of rotation of ratchet according to instructions for use, the plate fixed handle, and rotational sleeve rapidly, it is outer or be retracted in the sleeve to make guy hook stretch out sleeve fast, uses convenient and labor-saving.
Description of drawings
Fig. 1 is the structural representation of the turnbuckle of band ratchet mechanism:
Fig. 2 is the A-A position sectional view of Fig. 1 ratchet under a kind of state;
Fig. 3 is the A-A position sectional view of Fig. 1 ratchet under another kind of state.
Wherein: 1, cylindrical shell; 2, nut; 3, nut; 4, sleeve; 5, hollow guy hook; 6, guy hook; 7, ratchet; 8, handle; 9, positioning sleeve; 10, pin; 11, ratchet; 12, teeth groove.
Specific embodiments
The utility model is further described below in conjunction with drawings and Examples.
The turnbuckle structural representation of expression band ratchet mechanism among Fig. 1.It comprises cylindrical shell 1, two ends of cylindrical shell 1 are fixedly connected with the opposite nut of rotation direction 2, nut 3 respectively, form the sleeve 4 in two end band rotation direction opposite threads holes, respectively be equipped with and the match guy hook of threaded rod of sleeve screw at two ends of sleeve 4, it is hollow section that the threaded rod of a guy hook is arranged in two guy hooks, be hollow guy hook 5, the screw diameter of another guy hook 6 can be inserted in the hole of hollow guy hook 5 less than the internal diameter of hollow section.Be fixed with ratchet 7 on the sleeve 4, the positioning sleeve 9 of handle 8 is enclosed within the outer rim of sleeve 4, but the ratchet 11 of break-in is housed by pin 10 on the handle 8.
Fig. 2 is the A-A position sectional view of Fig. 1 ratchet 11 under a kind of state.Expression is when handle 8 clockwise rotates among the figure, and the ratchet 11 that is contained on the handle 8 is embedded in the teeth groove 12 of ratchet 7, promotes ratchet 7 also by clockwise rotating, and rotates thereby drive sleeve 4.When handle 8 rotated counterclockwise, the ratchet 11 that is contained on the handle 8 slipped on the back of tooth of ratchet 7, at this moment ratchet 7 transfixions.Handle 8 comes back rotation like this, ratchet 7 moves in the direction of the clock all the time, according to the different rotation directions of sleeve 4 two end screw threads, the guy hook 5 in sleeve 4, guy hook 6 stretch out outside the sleeve 4 simultaneously or are retracted in the sleeve 4, to regulate the distance between two guy hooks easily.
Fig. 3 is the A-A position sectional view of Fig. 1 ratchet 11 under another kind of state.Expression is when handle 8 rotates counterclockwise among the figure, and the ratchet 11 that is contained on the handle 8 is embedded in the teeth groove 12 of ratchet 7, promotes ratchet 7 also by rotating counterclockwise, and rotates thereby drive sleeve 4.When handle 8 clockwise rotated, the ratchet 11 that is contained on the handle 8 slipped on the back of tooth of ratchet 7, at this moment ratchet 7 transfixions.Handle 8 comes back rotation like this, ratchet 7 is all the time by counterclockwise rotating, according to the different rotation directions of sleeve 4 two end screw threads, the guy hook 5 in sleeve 4, guy hook 6 stretch out outside the sleeve 4 simultaneously or are retracted in the sleeve 4, to regulate the distance between two guy hooks easily.
Claims (3)
1, a kind of turnbuckle with ratchet mechanism comprises the guy hook that the band screw rod that matches with the sleeve screw is housed on sleeve with threaded hole, the sleeve, it is characterized in that being equipped with on the sleeve ratchet mechanism, and ratchet is contained on the sleeve, and ratchet is contained on the handle.
2, the turnbuckle of band ratchet mechanism according to claim 1, but the ratchet mechanism that it is characterized in that on the sleeve being adorned is the ratchet mechanism of break-in.
3, the turnbuckle of band ratchet mechanism according to claim 1 is characterized in that two ends of sleeve have the opposite screwed hole of rotation direction.
