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 creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

a steel pipe cutting clamp comprises a clamp body 1, the clamp body 1 comprises a base 110, a first cavity 111 is formed in the base 110, a screw rod 112 is fixedly mounted in the first cavity 111 through a bearing, threads on two sides of the screw rod 112 are opposite, one side of the screw rod 112 penetrates through the base 110 and extends to the outside, sliding blocks 113 are mounted on two sides of the outer surface of the screw rod 112 through threads, fixing plates 114 are fixedly mounted at the top ends of the sliding blocks 113, a handle 117 is fixedly mounted on one side of the screw rod 112, fixing blocks 119 are fixedly mounted on one sides, close to each other, of the two fixing blocks 114, a second sliding groove 120 is formed in one side, close to each other, of the two fixing blocks 119, a second sliding block 121 is slidably mounted in the second sliding groove 120, a clamping ring 122 is fixedly mounted on one side, the handle 117 is rotated by a worker, and the screw rod 112 can rotate, because the screw threads on the two sides of the screw rod 112 are opposite, the sliding blocks 113 on the two sides can be made to approach each other to drive the clamping ring 122 to approach each other to clamp and fix the steel pipe, and the second sliding block 121 is slidably mounted inside the second sliding chute 120, so that the worker can move the second sliding block 121 upwards to disassemble the clamping ring 122, so that the worker can replace the clamping rings 122 of different models for use, one side of the second sliding chute 120 is provided with the limiting mechanism 2, the limiting mechanism 2 comprises a second cavity 210, one sides of the two second sliding chutes 120 far away from each other are provided with the second cavity 210, the insides of the second cavities 210 are fixedly provided with the springs 211, one sides of the two springs 211 near each other are fixedly provided with the limiting columns 212, one sides of the two second sliding blocks 121 far away from each other are provided with the limiting holes 213, and the limiting columns 212 are inserted and mounted inside the limiting holes 213, one side of spacing post 212 and spacing hole 213 all are the arc, utilize spacing post 212 to insert to the inside of spacing hole 213 to can be with the firm inside of fixing at second spout 120 of second slider 121, make grip ring 122 firmly fixed, increased the fastness of structure, made things convenient for staff's use.

The shape of the clamp ring 122 is semicircular, and the clamp ring 122 is semicircular, so that the clamp ring 122 can be matched with the shape of the steel pipe, and the clamp ring 122 can be clamped and fixed more stably.

The balls 123 are uniformly arranged on the side, close to each other, of each of the two clamping rings 122, the balls 123 are spherical, and the balls 123 are spherical, so that when the steel pipe moves on the inner side of the clamping ring 122, the balls 123 roll, the steel pipe can move on the inner side of the clamping ring 122 conveniently, and the practicability of the structure is improved.

The bottom of sliding block 113 all fixed mounting have first slider 115, first spout 116 has all been seted up to the both sides of first cavity 111 bottom, first slider 115 slidable mounting is to the inside of first spout 116, when sliding block 113 slides in the lead screw 112 outside, first slider 115 can slide in the inside of first spout 116, thereby can make the more stable that sliding block 113 removed, prevent that fixed plate 114 from appearing the phenomenon of rocking when removing, increased the stability of structure.

The outside fixed mounting of handle 117 bottom has slipmat 118, and slipmat 118's material is nitrile rubber, utilizes slipmat 118 can increase the frictional force between staff's palm and the handle 117 to when making the staff rotate handle 117, gliding phenomenon can not take place, thereby increased staff's use and experienced.

The working principle is as follows: when the staff is using, place the steel pipe between two grip rings 122, the staff can be through rotating handle 117 afterwards, thereby can make handle 117 rotate, make handle 117 drive lead screw 112 and rotate, because the screw thread of lead screw 112 both sides is opposite form, thereby can make the sliding block 113 of both sides close to each other, first slider 115 slides in the inside of first spout 116 simultaneously, it is close to each other to drive grip ring 122 on the fixed plate 114 of both sides, it is fixed to carry out the centre gripping to the steel pipe, the staff can cut the steel pipe afterwards, when the staff need remove the steel pipe, promote the steel pipe, make the steel pipe remove to one side, simultaneously because ball 123 is spherical, thereby make the steel pipe when removing, ball 123 can roll, reduce the frictional force between grip ring 122 and the steel pipe, it is more convenient to make the steel pipe remove.

When the staff need dismantle grip ring 122, utilize second slider 121 to slide in the inside of second spout 120, make the staff can rebound second slider 121, thereby extrude spacing post 212, make spacing post 212 shrink inwards, extrude spring 211, can take out second slider 121 from the inside of second spout 120, when the staff needs to install the grip ring 122 of different models, slide second slider 121 to the inside of second spout 120, when second slider 121 slides to the bottom of second spout 120, utilize the inertia of spring 211, thereby can be with spacing post 212 bullet to the inside of spacing hole 213, fix the inside at second spout 120 with second slider 121 is firm, can accomplish the installation to grip ring 122, the use of staff has been made things convenient for.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
