Abstract

The utility model relates to a fast detachable connecting ring which can pass the pulley groove and be used for connecting the steel wire ropes for lifting. The connecting ring is characterized in that the groove, which is anastomotic with the locking plate, is arranged both on the detachable ring and the flat section shaft sleeve. Due to the different position of the locking plate, the long edge of the flat section shaft sleeve seals placket of the C-shaped ring to lock the detachable ring, or the short edge of the flat section shaft sleeve positions at the placket of the C-shaped ring to detach the detachable ring. The intermediate cross-section of the C-shaped ring transition as smooth circular arc to the cross-sections of the two end. The utility model has the advantages of increasing the area of the risky cross-section, enhancing the strength, beling favorable to the rolling of the connecting ring in the pulley groove, and reducing the frictional resistance. The utility model can be used for the connection between the chain rings and the connection between the chain ring and the steel wire rope.

Description

Fast detachable connecting ring

The utility model relates to a kind of being used for and is connected between hoist rope and the wire rope, and can belong to engineering element or parts class by the quick-detachable connecting ring of pulley groove, is mainly used in band, cable or rope, the chain of transmission; And used main accessories.

In known technology, be used for being connected between hoist rope and the wire rope, and can pass through the quick-detachable connecting ring of pulley groove by " C " shape ring, fulcrum, flat axle sleeve, locking plate, middle plug screw, spring, hexagonal socket head plug, stripping ring are formed, connect flat axle sleeve and stripping ring by middle plug screw, on the plug screw, middle plug screw utilized screw thread to be spun on the stripping ring inboard in the middle of flat axle sleeve sky was enclosed within, for preventing thread looseness, fastening from two different direction with straight pin in threaded middle.Its deficiency is that plug screw connects in the middle of utilizing, complex structure, be difficult for installing, and because structural layout, flat axle sleeve outer rim is thin, yielding damage when hexagonal socket head plug is met axial force by chance, is met contamination during for example by pulley groove, easily with length of spring compressed, cause locking to come off, the side profile of " C " shape ring is unreasonable in addition, and its ring intermediate cross-section is to the linearly transition of two tip sections, the crooked position intensity difference is fragile, and it is poor to coincide during by pulley groove, and surface friction drag is big, has aggravated the wearing and tearing of connecting ring.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and provide a kind of intensity of easy installation reliable lock simple in structure high pass through the little quick-detachable connecting ring of pulley groove resistance.

In order to achieve the above object, the utility model technical solution is:

Inner side end at stripping ring has the groove that matches with the locking plate shape; Have another relative free side end face of a side to have one at locking plate, pass the hole of flat axle sleeve on the axle after the mounting spring, its axle head has groove, and back-up ring is arranged on the groove, can prevent flat axle sleeve axial float; The flat axle sleeve touches a side end face mutually with stripping ring and has the groove that matches with the locking plate shape; The end face that fulcrum inserts in the flat axle sleeve has a hole, leaves the space for the axial displacement of locking plate axle; " C " shape ring intermediate cross-section is smoothly circular-arc to two tip section transition arcs, increases connecting ring crooked position cross section, is beneficial to carrying, and surface friction drag is little when making " C " shape ring by pulley groove.

Below in conjunction with details and the working procedure of accompanying drawing detailed description according to the concrete device that the utility model proposes.

Fig. 1 is according to the quick-detachable connecting ring that the utility model proposes.

Fig. 2 is the side view of connecting ring.

Locking plate axle (6) inserts from stripping ring (2) is inboard, locking plate (5) embeds in the groove (9) of stripping ring (2) inner side end, locking plate axle (6) cover upper spring (7) back screws in hexagonal socket head plug (8) and fixes as axle head, make it to fuse, spring (7) one side bearings are on stripping ring (2), and opposite side is bearing on the hexagonal socket head plug (8).Another axle (11) cover upper spring (12) of locking plate (5) passes the hole (13) of flat axle sleeve (4), locking plate embeds in the groove (16) of flat axle sleeve (4), one side bearing of spring (12) is on locking plate (5) side, opposite side is bearing on the flat axle sleeve (4), axle (11) stretches out outside the hole (13) of flat axle sleeve, back-up ring (15) is installed on axle (11) axle head groove (14), and back-up ring (15) can prevent the axial float of flat axle sleeve (4) on axle (11).Fulcrum (3) inserts in the flat axle sleeve (4) and with straight pin and fixes, end face in fulcrum (3) inserts flat axle sleeve (4) has a hole (17), the axle head of locking plate axle (11) can insert in it, and hole (17) leave the space for the axial displacement of locking plate axle (11).

Fulcrum (3), flat axle sleeve (4), spring (12), locking plate (5), spring (7), stripping ring (2), hexagonal socket head plug (8) is mounted to one.When hexagonal socket head plug (8) is subjected to axial pressure pressure spring (7) and (12), locking plate (5) breaks away from the groove (9) of stripping ring (2), enter fully in the groove (16) of flat axle sleeve (4), this moment, then locking plate (5) drove flat axle sleeve (4) rotation if rotate hexagonal socket head plug (8).When the axis normal of the minor face of flat axle sleeve (4) and stripping ring (2), can be by the opening of " C " shape ring, fulcrum (3) inserts the hole (19) of " C " shape ring, after stripping ring (2) embeds the groove of " C " shape ring, rotate hexagonal socket head plug (8) once again, when making the parallel axes of the minor face of flat axle sleeve and stripping ring (2), the long banding that is the flat axle sleeve is lived the opening that " C " shape is encircled, because of spring (12), (7) elastic force, locking plate (5) embeds in the groove (9) of stripping ring (2) again, groove (9) is placed restrictions on locking plate (5), flat axle sleeve (4) rotates, stripping ring (2) and " C " shape ring fuse, this moment, connection finished, and vice versa.

In addition,, locate for crooked 45 °～48 °, be dangerouse cross-section at " C " shape ring through theoretical and facts have proved, after promptly " C " shape rim bearing carries, stressed herein maximum.Figure two has represented that the intermediate cross-section of this " C " shape ring is smoothly circular-arc (18) to two tip section transition arcs, obviously increased the area of dangerouse cross-section, improved composite bending modulus, strengthened intensity herein, and smoothly circular-arc (18) favourable connecting ring rolls the resistance of reducing friction in pulley groove.

The following advantage that the utility model has compared to existing technology:

Saved middle plug screw connector, simple in structure, be easy to install, and the flat sleeve size is abundant, not fragile, increased spring, the locking plate axle is difficult for play, and " C " shape ring intermediate cross-section is level and smooth circular-arc transition to two end sections, has not only increased the dangerouse cross-section area, improve intensity and be conducive to connecting ring and in pulley groove, roll, reduced frictional resistance. This connecting ring not only can be used for the connection between the steel wire rope rope, also can be used for the connection between the chain link, or being connected between chain link and the rope.
