Abstract

The utility model discloses a kind of stone tongs, comprise left jig arm, right jig arm, ring chain and link, left jig arm and right jig arm are divided into handle and claw two parts, centre is connected by rotating shaft, it is characterized in that, being provided with pre-tightening apparatus between described handle, slides spacing connection with left and right handle in the two ends of pre-tightening apparatus.Because the predetermincd tension of spring makes workpiece or product press from both sides tighter and tighter in uphill process in the utility model hoisting process; thus substantially increase the safety of lifting; this external claw pawl is socketed abrasion cushion with it; the contact of product and claw is made to have buffering effect; effectively prevent the scratch between claw and product, serve good protected effect.

Description

A kind of stone tongs

Technical field

The utility model belongs to and relates to a kind of hanging device, specifically relates to a kind of stone tongs.

Background technology

Attack in machine worktable production process at brill, large foundry goods is generally all designed with hoisting ring or hole for hoist, little foundry goods does not then have, workman ties up anti-shake rope on any pipeline of equipment, and angle and controlling point are not easily grasped, and often cannot link up with, or that hangs is insecure, frequent appearance unhook landing even scratches the phenomenon of product, therefore causes lifting efficiency low, and operation behaviour is lack of standardization and there is larger potential safety hazard.

Summary of the invention

It is simple, esy to use, safe and reliable that the purpose of this utility model is to provide a kind of structure, and greatly improve the stone tongs of lifting efficiency.

Technical solutions of the utility model: a kind of stone tongs, comprise left jig arm, right jig arm, ring chain and link, left jig arm and right jig arm are divided into handle and claw two parts, centre is connected by rotating shaft, being provided with pre-tightening apparatus between described handle, slides spacing connection with left and right handle in the two ends of pre-tightening apparatus.

Described pre-tightening apparatus comprises the spring being arranged on and connecting between guide pin bushing on the handle of left and right and two guide pin bushings, and guide pin bushing is provided with spacing hole, and handle is evenly provided with several positioning through hole, and guide pin bushing is connected with positioning through hole corresponding on handle by spacing hole and bolt.

Described claw is provided with the loss prevention cover for being connected with claw pawl body, and it is open design that one end is overlapped in loss prevention, and its cover figure shape and claw coincide, and the open end of loss prevention cover is provided with sticking belt, and loss prevention cover is fixed on it the pawl of claw by sticking belt.

The inner sleeve face of loss prevention cover is provided with one deck dentation cushion rubber, and loss prevention cover is enclosed within it the first half of claw pawl body.

The utility model by arranging spring between two jig arm, by the predetermincd tension of spring, workpiece or product are pressed from both sides in hoisting process tighter, and the predetermincd tension of spring adapts to different products by regulating, very safe and practical, in addition, claw place arranges loss prevention pad, make the contact of product and claw have buffering effect, and actv. prevents product to be scratched in hoisting process.

Accompanying drawing explanation

Fig. 1 is the utility model embodiment 1 structural representation.

In figure: left jig arm 1, right jig arm 2, high strength nut 3, ring chain 4, link 5, spring 6, claw 7, loss prevention cover 8, guide pin bushing 9.

Detailed description of the invention

Embodiment: as shown in Figure 1.

A kind of stone tongs, comprise left jig arm 1, right jig arm 2, ring chain 4 and link 5, left jig arm 1 and right jig arm 2 are divided into handle and claw 7 two parts, and centre is connected by rotating shaft, being provided with pre-tightening apparatus between handle, slides spacing connection with left and right handle in the two ends of pre-tightening apparatus.Described pre-tightening apparatus comprises the spring 6 being arranged on and connecting between guide pin bushing 9 on the handle of left and right and two guide pin bushings 9, guide pin bushing 9 is provided with spacing hole, handle is evenly provided with several positioning through hole, guide pin bushing 9 is connected with positioning through hole corresponding on handle by spacing hole and bolt, be arranged in the mutually level corresponding hole site of two jig arm by mobile guide pin bushing 9, can effectively reasonably regulate the predetermincd tension of spring, to adapt to different products or workpiece.

In addition; loss prevention claw 7 is provided with for being connected with claw pawl body overlaps 8; it is open design that 8 one end are overlapped in loss prevention; its cover figure shape and claw 7 coincide, and the open end that loss prevention overlaps 8 is provided with sticking belt, and the first half being enclosed within claw 7 pawl body by thread gluing with it and wrapped; and a layer dentation cushion rubber is set on the inner sleeve face of loss prevention cover 8; make the contact of product and claw have buffering effect, effectively prevent the scratch between claw 7 and product, serve good protected effect.Because the predetermincd tension of spring makes to press from both sides tighter and tighter in workpiece or product uphill process in hoisting process, substantially increase the safety of lifting.
