Description
Technical field
The utility model relates to a kind of pull bar, especially a kind of for cushioning the wind-proof pull rod of tension.
Background technique
At the larger special weather of the wind-force such as typhoon, the building that many frameworks are built, such as crops booths etc., usually can't stand wind-force because holding, and are blown down or destroy.For problems, the most frequently used means are to utilize rope, turnbuckle etc. to reinforce, but because rope, turnbuckle etc. itself do not have flexible damping characteristics, usually do not have comparatively desirable effect, even because of the excessive building that damages required reinforcing of rope stretch amplitude.Also there is direct employing elastic rope as fastening, but the more difficult grasp adjusting of the elastic force of elastic rope, the too small fastening effect that do not have of elastic force, elastic force is excessive to be impacted building again.For this reason, there is a kind of wind-proof pull rod to be designed, make it have the function of tension, buffering adjusting.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is that a kind of wind-proof pull rod is provided to related domain, makes it solve the technical problem that the windproof tension effect of existing like product is not good enough, easily building is caused damage.Its objective is and be achieved through the following technical solutions.
A kind of wind-proof pull rod, this wind-proof pull rod comprises upper connecting rod, middle pull bar, tensioning sleeve, damping device, lower link, upper connecting rod one end is lanyard portion, the other end tensioning sleeve one end that is threaded.Its structure outline is that described damping device comprises spring, protecting cover, and described middle pull bar one end is provided with the welding base of disjunctor, described spring one end and welding base welding, and the other end is provided with carbine; Described protecting cover one end is provided with the through hole mating with middle pull bar bar portion, and the other end is uncovered; Described middle pull bar socket seal ring, described through hole stretches out from protecting cover inner side in middle pull bar bar portion, and described welding base, spring are limited in protecting cover, stretch out middle pull bar outside protecting cover be threaded successively locking nut and the described tensioning sleeve the other end; Described lower link one end is hook portion, and the other end is provided with the dog hole coordinating with described carbine, the bar portion of the lower link lock sleeve for locking spring hook and dog hole that is threaded, and this lock sleeve and described protecting cover open-mouth end inner side are for being slidably matched.By said structure, the tension force that utilizes upper connecting rod, middle pull bar, tensioning sleeve to realize this wind-proof pull rod regulates.Utilize spring to realize the buffer function of this wind-proof pull rod.Adopt protecting cover, seal ring, spring is played to the effect of waterproof, protection, extend the working life of this wind-proof pull rod.
The structure of described middle pull bar socket seal ring, the locking nut that is threaded replaces with welding base and protecting cover one end welded seal of middle pull bar, and middle pull bar and protecting cover are directly connected as a single entity.Adopt welded structure, be difficult for loosening.
The side face of described lock sleeve is provided with annular seal groove, and annular seal groove is embedded in O-ring seal.Further to improve the waterproof sealing of spring.
The sliding stroke of described lock sleeve in described protecting cover is greater than the tensile elongation forming when described spring bears maximum pull.The object of this design is to prevent in the normal drawing process of spring because lock sleeve is from deviating to cause the problem of buffer invalidation in protecting cover.
The rectangular frame structure of described tensioning sleeve, tensioning sleeve two ends are provided with tapped hole.Adopt rectangular configuration, not only economize material, and stressed even, guarantee effective intensity.
The utility model structure is comparatively simple, installs and uses comparatively quick and easyly, relies on locking, buffering to regulate and realizes good protection effect, and be suitable as the wind-proof device such as agricultural greenhouse and use, or the architecture advances of like product.
Brief description of the drawings
Fig. 1 is scheme one structural representation of the present utility model.
Fig. 2 is the part-structure exploded perspective view of Fig. 1.
Fig. 3 is scheme two structural representations of the present utility model.
In figure, the name of sequence number is called: 1, upper connecting rod, 2, tensioning sleeve, 3, middle pull bar, 301, welding base, 4, locking nut, 5, seal ring, 6, spring, 7, protecting cover, 701, through hole, 8, lock sleeve, 9, lower link, 901, dog hole.
Embodiment
Now by reference to the accompanying drawings, the utility model is further described.
Be scheme one structure as shown in Figure 1 and Figure 2.This wind-proof pull rod comprises upper connecting rod 1, tensioning sleeve 2, middle pull bar 3, locking nut 4, seal ring 5, spring 6, protecting cover 7, lock sleeve 8, lower link 9.Concrete structure is: the bar portion of upper connecting rod, middle pull bar, lower link is equipped with screw thread, the rectangular frame structure of tensioning sleeve, and its two ends are provided with the tapped hole coordinating with upper connecting rod, middle pull rod screw.Upper connecting rod one end is provided with lanyard portion, and lanyard portion is hook or hanging ring, the be threaded tapped hole of tensioning sleeve one end of the upper connecting rod the other end.Middle pull bar one end is provided with the welding base 301 of disjunctor, welding base opposite side welding spring one end.Welding base, spring are placed in protecting cover, and protecting cover one end is provided with the through hole 701 coordinating with middle pull bar bar portion, and the other end is uncovered.After the bar portion socket seal ring of middle pull bar, stretch out through hole, the tapped hole of be threaded successively locking nut and the tensioning sleeve the other end.Seal ring is realized the sealing of protecting cover through hole under locking nut, welding base locking effect.The spring the other end is provided with carbine, and lower link one end is provided with the dog hole 90 coordinating with carbine, and the other end is provided with hook portion 1.Before carbine coordinates with enough holes, the bar portion of the lower link lock sleeve that is threaded; After carbine coordinates with dog hole, by screwing lock sleeve, the dog hole of the carbine of spring and lower link is locked mutually.When lock sleeve completes when locking, lock sleeve and protecting cover are and are slidably matched, and lower link is play the guiding role.
In said structure, the sliding stroke of lock sleeve in protecting cover is designed to be greater than the tensile elongation forming when spring bears maximum pull, prevents that the open-mouth end that departs from protecting cover because of lock sleeve from causing buffer invalidation.
Be illustrated in figure 3 scheme two structures.Specifically by scheme one, the welding base that middle pull bar socket seal ring the scenario-frame that connects locking nut replace with middle pull bar directly and protecting cover one end welded seal, can enter in protecting cover from protecting cover through hole by anti-sealing equally.
Due in use, middle pull bar, upper connecting rod are to be positioned at protecting cover top, and lower link is positioned at protecting cover bottom, therefore in the face of situations such as rainy days, the through hole of protecting cover upper end needs sealing, and below is generally without sealing.Consider further raising sealing effect, sealing configuration also can be set between protecting cover lower end and lock sleeve, lock sleeve side face is provided with annular seal groove, and O-ring seal is set in annular seal groove.
When concrete use, the fastening pieces such as the lanyard portion of upper connecting rod and the hook portion connecting rope of lower link, after tension rope, by regulating tensioning sleeve, tension adjusting.After installation, can rely on spring to cushion, effectively alleviate the excessive and impact that building is caused of wind-force.
