In the application of the drag chain, the application of the drag force is the most basic working condition of the drag chain.
In the pulsating pulling of the chain, the links are in rigid contact of 'hard to hard', once the pulling force breaks through the range which can be borne by the chain, the chain can be irreversibly damaged, and in the past, the weak part of the chain is broken. After the chain is broken, the chain has to be connected again, the normal working condition is delayed, and the labor and the time are wasted.
SUMMERY OF THE UTILITY MODEL
The utility model provides a chain based on nimble use under pulsation drag-pull impact has solved the easy cracked problem of current chain rigid contact.
The technical scheme of the utility model is realized like this: the utility model provides a chain based on nimble use under pulsation drag is strikeed, includes box body and lid, the middle part and the montant of lid be connected, the montant is connected with the card foot, the middle part of box body is equipped with the kelly, the cooperation is established with the kelly card to the card foot, the both ends of box body are equipped with the pole groove, the pole inslot is equipped with the connecting rod, the one end that the connecting rod stretched into the box body is connected with the clamp plate, be equipped with the cushion between clamp plate and the box body, the one end that the connecting rod stretches out the box body.
The connecting ring, the connecting rod and the pressure plate are integrated.
The box body is cylindrical.
The cushion blocks are arranged in blocks.
The cushion block is divided into two semi-annular blocks.
The end surface of the clamping pin contacted with the clamping rod is arc-shaped.
The clamping rod is welded in the box body.
The box body in be equipped with and carry out spacing rotary groove to the card foot, the rotary groove is circular groove.
The utility model has the advantages that: the chain is additionally provided with the counter-pulling cushion block to buffer the pulling force applied to the chain, so that the damage of the chain during excessive pulling is effectively avoided; the box body is convenient to open and close, the cushion blocks are arranged in a split mode, convenience and rapidness in cushion block replacement are guaranteed, and maintenance time is shortened.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view of the box body of the present invention.
In the figure: 1-chain ring, 2-connecting ring, 3-connecting rod, 4-pressing plate, 5-box body, 6-rod groove, 7-cushion block, 8-box cover, 9-vertical rod, 10-clamping foot, 11-clamping rod and 12-rotary groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1 and 2, a chain flexibly used under pulsating pulling impact comprises a chain ring 1, a connecting ring 2, a connecting rod 3, a pressing plate 4, a box body 5, a rod groove 6, a cushion block 7, a box cover 8, a vertical rod 9, a clamping pin 10, a clamping rod 11 and a rotary groove 12.
The box body 5 is cylindrical, the side part of the box body is provided with an opening, and the two ends of the box body are provided with rod grooves 6. The rod groove is a long hole groove, and the opening direction of the rod groove is the same as that of the box body. The rod grooves 6 at two ends are respectively provided with a connecting rod 3, one end of the connecting rod 3 extending into the box body 5 is integrally connected with the pressing plate 4, one end of the connecting rod 3 extending out of the box body 5 is integrally connected with the connecting ring 2, and the connecting ring 2 is connected with the chain ring 1. Thereby connecting the cassette between the two links.
A cushion block 7 is arranged between the pressure plate 4 and the box body 5, and the cushion block 7 is divided into two semi-annular blocks which are arranged on the left side and the right side of the connecting rod. When the chain is pulled, the cushion block clamp buffers between the pressing plate and the box body, so that the rigid deformation of the chain is reduced, and the damage to the chain is reduced.
The box cover covers the opening of the box body to seal the box body. The middle part of lid 8 is connected with montant 9, and montant 9 is connected with card foot 10, and the middle part welding of box body 5 is equipped with clamping bar 11, and the cooperation is established with the card of clamping bar 11 card to card foot 10. The clamping pin is clamped in the clamping rod, the box cover is fastened and fixed on the opening, the clamping pin is rotated by 90 degrees, the clamping pin is separated from the clamping rod, and the box cover can be detached, so that the connecting rod is taken out, and the cushion block is replaced.
The terminal surface of card foot 10 and the contact of kelly 11 is the arc, when the card foot card is gone into in the kelly, needs rotate the card foot, and curved contact surface for chucking power between card foot and the kelly crescent guarantees that the lid card establishes stably, is difficult for dropping. The box body 5 is internally provided with a rotary groove 12 for limiting the clamping pin 10, the rotary groove 12 is a circular groove, and the rotary groove limits the clamping pin when the clamping pin rotates, so that the dislocation of the box cover is avoided, and the accurate positioning is ensured.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
