Description

A kind of dress is got multipurpose link efficiently

The utility model relates to a kind of being applicable to and is connected object, especially for the link of connections such as sports apparatus, hinge shaft sleeve.

At present, commonly used connection set such as sports apparatus, hinge with bolt, nut by being threaded or using rivet, before a kind of to exist dismounting efficient low, inconvenient operation, occur moving back shortcomings such as silk, stripped thread easily, a kind of the existing in back can not arbitrarily be dismantled the construction process complexity, use shortcomings such as inconvenience, historical facts or anecdotes can not be satisfactory in using.

In order to overcome the shortcoming of existing connection set, purpose is that proposition is a kind of easy to operate, and dress is got quick, technology is simple, cost is low, antivibration is effective, silk, stripped thread can not occur moving back and can get multipurpose link efficiently by standardized a kind of dress, to remedy present deficiency.

According to the utility model, a kind of dress is got multipurpose link efficiently, it is characterized in that this link comprises a coupling bar and the female and at least one spring of a solid locking bolt, be processed with at least one boss on described solid locking bolt mother's the hole wall, be processed with at least onely in order to stoping solid locking bolt mother and boss thereof around axle motion and be locked J type groove to stop solid locking bolt mother to deviate from from coupling bar on the key of described coupling bar, described J type groove matches with boss on the solid locking bolt mother hole wall.Gu the locking bolt mother can be with its hole wall on boss be the separate component (as adopting mould rammer technology) of one, can also be to assemble the all-in-one-piece assemblying body with the boss pin by the female main body of solid lock inspection, can also be the thing that is connected that is processed with blind hole or through hole and boss on request.The key of coupling bar can have multiple section shape, and is wherein better circular; The J type groove that coupling bar is processed above can be more than one, and can be multiple shape; It is first-class that one end of coupling bar can be tack or tip or semicircle, on the termination of the other end operating device of being convenient to operate can be arranged, and this operating device can be various ways such as interior hexagonal formula, outer-hexagonal formula, cross slot type, straight groove formula; Gu also the operating device of being convenient to operate can be arranged on the locking bolt mother.Can be more than one with coupling bar or the female spring that cooperates of solid locking bolt, and but multiple shape.Gu the boss on the female hole wall of locking bolt can be more than one, preferably and the J type groove on the coupling bar supporting, and can be multiple shape.A kind of dress is got efficiently the multipurpose link and can be made as metal, macromolecular material etc. by multiple material, can pass through kinds of processes, forms as methods such as casting, die forging, die casting, punching press, cold-heading, machining, welding, injection mouldings.

(can be during use according to usage requirement, select common spring or high strong spring, it now is example with the specific use, select high strong spring for use, use the special device dress to get, can be with reference to Fig. 1), the spring contraposition is packed into coupling bar (certainly earlier, end that also can bolt to be connected packs into coupling bar with the spring contraposition from being connected after through hole on thing A spare and the B spare passes again), end with coupling bar inserts and passes the through hole that is connected on thing A spare and the B spare again, to consolidate the female contraposition of locking bolt then and pack into the coupling bar that passes in the hole, simultaneously the dop on the special device is blocked the operating device of this link and put in place, this special device of last operation, (quantity according to boss is determined required angle to finish roof pressure and put in place → rotate 60 °, be generally 90 °, 60 °, 45 °, also can select other angle for use) → (unclamping simultaneously) entire exercise return, promptly at first roof pressure with length of spring compressed (general instrument and roof pressure power can not with high-strength length of spring compressed), make boss on the female hole wall of solid locking bolt enter in the J type groove on the coupling bar and put in place, remove roof pressure power (return and unclamp) after rotating 60 ° simultaneously, Gu the boss on the locking bolt mother has promptly sticked into the J type fluted tail on the coupling bar by the rebounding force of spring.At this moment, because the effect of spring, J type fluted tail has promptly been pinned boss, and solid locking bolt mother can not be rotated, and shelves have been lived boss and stoped solid locking bolt mother to deviate from from coupling bar again simultaneously, promptly lock and install.When this link that will install when need takes off, still operate this special device, same entire exercise when finishing and installing, promptly roof pressure put in place → rotate 60 ° → return and unclamp, just can take off.

The utlity model has following major advantage: (1) is widely used, and no matter is bridge parts, lathe lower margin, movable dwellings, or hinge pivot pin, sports apparatus, and life preserver, emergent suspension hook, guided missile hanger etc. all can adopt; (2) material is easy to get, and technology is simple, and cost is low; (3) but standardization, can exchange, general; (4) linking intensity height, antivibration is effective, can absorb and slow down the impact energy that strong external force effect produces effectively; (5) easy and simple to handle, dress is got quick, and is solid and reliable.

Embodiment's accompanying drawings of the present utility model is as follows:

This link mainly have drawn from metal, macromolecular material etc. form through methods such as die forging, die casting, punching press, cold-heading, extruding, machining, injection mouldings.
