Abstract
The utility model provides a shackle device, and particularly relates to a hemispherical safety shackle, which comprises a shackle body and an insertion rod. Shackle heads at two ends of the shackle body are generally hemispherical; the surfaces of the shackle heads are in smooth transition with the shackle body; one end of each of the two shackle heads is provided with a circular hole; the other end of each of the two shackle heads is provided with a threaded hole; the inner lateral surface of each hemispherical shackle head is larger than the outer lateral surface thereof; one end of the insertion rod is provided with threads; the other end of the insertion rod is provided with a projection for turning the insertion rod; the insertion rod is mounted together with the shackle body in a threaded manner after transversely penetrating through the circular holes on the shackle heads; and a pin hole is arranged at the tail end of the insertion rod and exposed outside the shackle body after the insertion rod and the shackle body are assembled. By the aid of the technical scheme, the shackle with the hemispherical heads has the advantages that raw materials can be saved by 6% and production cost is reduced without reducing tension resistance, a pin is inserted into the pin hole arranged at the tail end of the insertion rod so that the insertion rod is more firmly mounted on the shackle body, and the purposes of economization and safety are achieved.
Description
Technical field
The utility model provides a kind of fastener device that unloads, and particularly relates to a kind of hemisphere type insurance and unloads fastener device.
Background technique
Mainly by unloading button and inserted link is formed, the head that unloads button of conventional shackle is an intercept sphere in shackle at present, and when shackle was subjected to force-extension, the inboard of unloading the button head when shackle is subjected to stretching became the place of stressed maximum, unloads button head materials and exists and waste; Simultaneously, inserted link was deviate from from the head that unloads button easily when shackle was subjected to stretching, and caused security incident.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of hemisphere type insurance shackle is provided, and reduces the material materials of shackle under the situation that does not influence pulling force, can also prevent that inserted link from deviating from, and reaches and saves and purpose of safety.
The utility model is to realize like this, a kind of hemisphere type insurance shackle, it is by unloading button and inserted link is formed, it is characterized in that, the described discount that unloads that unloads the button two ends is roughly the hemisphere type body, the surface with unload button and seamlessly transit, described two unload discount wherein an end be provided with circular hole, the other end is provided with tapped hole, the inner side surface that unloads discount of described hemisphere type body is greater than outer side surface, described inserted link one end has screw thread, the other end is provided with the thrust that is used to rotate inserted link, inserted link is horizontally through behind the circular hole that unloads on the discount and unloads button and is installed together by screw thread, the end of inserted link is provided with pin-and-hole, inserted link with unload button assembling back pin-and-hole and expose in shackle external.
The end that described inserted link is provided with the thrust that is used to rotate inserted link also is provided with greater than the plate washer that unloads the circular hole on the discount.
The described button that unloads is the U type, and the tension effect is best.
Adopt the head hemisphere type shackle of the technical program, under the situation that does not reduce resistance to tension, can save raw material 6%, reduce production costs, simultaneously, the pin-and-hole that the end of inserted link is provided with is at inserted link and expose in shackle external after unloading the button assembling, insert and inserted link to be installed in behind the latch to unload on the button more firm, reached saving and purpose of safety.
Description of drawings
Fig. 1 is the plan view of the utility model structure.
Fig. 2 is the left view of Fig. 1.
Wherein, 1-unloads button, the 2-thrust, and the 3-plate washer, the 4-inserted link, 5-unloads discount, the 6-pin-and-hole.
Embodiment
Below in conjunction with accompanying drawing concrete structure of the present utility model and principle are described further.
As shown in the figure, a kind of head hemisphere type shackle of the utility model, it is by unloading button 1 and inserted link 4 is formed, it is characterized in that, the described discount 5 that unloads that unloads button 1 two ends is roughly the hemisphere type body, the surface with unload button 1 and seamlessly transit, described two unload discount 5 wherein an end be provided with circular hole, the other end is provided with tapped hole, the inner side surface that unloads discount 5 of described hemisphere type body is greater than outer side surface, described inserted link 4 one ends have screw thread, the other end is provided with the thrust 2 that is used to rotate inserted link, inserted link 4 is horizontally through behind the circular hole that unloads on the discount 5 and unloads button 1 and be installed together by screw thread, the end of inserted link 4 is provided with pin-and-hole 6, inserted link 4 with unload button 1 assembling back pin-and-hole 6 and expose outside unloading button 1; The end that described inserted link 4 is provided with the thrust 2 that is used to rotate inserted link also is provided with greater than the plate washer 3 that unloads the circular hole on the discount 5.
The described button 1 that unloads is the U type, and the tension effect is best, unloads button 1 certainly and also can be designed as other shapes.
The head hemisphere type shackle of the utility model big unloads that discount 5 inboardly strengthens, the outside dwindles with stressed in the using process, makes the hemisphere type body, can reduce the materials 6% of shackle like this under the constant situation of resistance to tension, can reduce production costs.Simultaneously, insert the installation fastness that latch has increased inserted link 4 in the pin-and-hole 6 that inserted link 4 ends are provided with, make inserted link 4 when being subjected to stretching, be difficult for deviating from, avoided security incident, improved Security.
