Description

Jackscrew with protection effect

Technical Field

The utility model relates to a jackscrew specifically relates to a jackscrew with protection effect.

Background

The jackscrew all need be a part that uses on a lot of equipment and products, current jackscrew all is that integrative metal material makes, the one end of the tight other products in jackscrew top is metallic, when pushing up other parts like this, damage to the tight part in top very easily, thereby cause the part to dismantle or use the problem, but the jackscrew is for the joint strength who guarantees when using, can not change the material of jackscrew into than soft material again, for this reason, we provide a jackscrew with the guard effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a jackscrew with protection effect is provided, it has the metal material to make to have solved current jackscrew, causes the problem of damage to other parts during the use easily.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a jackscrew with protection effect, includes lead screw, rotating head and tight head in top, the integrative fixedly connected with rotating head of lead screw right-hand member, the blind hole has been seted up to the lead screw left end, the tight head in top is installed in fixed grafting in the blind hole.

On the basis of the scheme, the outer wall of the rotating head is provided with reticulate patterns and knurls.

On the basis of the scheme, the tightening head is made of plastic, and anti-skid grains are arranged on the vertical surface of the left side of the tightening head.

On the basis of the scheme, the maximum outer diameter of the jacking head is smaller than the bottom diameter of the threads on the screw rod.

Compared with the prior art, the utility model beneficial effect who has is: the utility model provides a jackscrew with protection effect has improved current jackscrew structure, has set up the tight head in top that plastic materials made in the tight end in top of jackscrew, can enough reach the tight effect in top, can avoid again causing the damage to other parts, has made things convenient for people's use greatly, the utility model has the advantages of simple and reasonable structure, the tight frictional force in top is big during the use, and the protection effect is good, and the cost of manufacture is low, and the practicality is strong.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1 to 2, the jackscrew with the protection effect comprises a screw rod 1, a rotating head 2 and a jacking head 5, wherein the rotating head 2 is fixedly connected to the right end of the screw rod 1, the rotating head 2 is convenient for rotating the screw rod 1, a blind hole 4 is formed in the left end of the screw rod 1, the jacking head 5 is fixedly inserted in the blind hole 4, and the jacking head 5 is convenient for jacking other parts.

The outer wall of the rotating head 2 is provided with reticulate patterns and knurls 3, and the reticulate patterns and the knurls 3 are convenient for screwing the rotating head 2; the puller head 5 is made of plastic, and when the plastic material is used for tightly pulling other parts, the other parts cannot be damaged; the left vertical surface of the tightening head 5 is provided with anti-skid grains, so that the friction force can be increased; the maximum outer diameter of the puller head 5 is smaller than the bottom diameter of the threads on the screw rod 1, so that the butt joint of the threads on the screw rod 1 and threaded holes on other parts is not hindered.

The utility model discloses a principle and advantage: the utility model provides a jackscrew with protection effect, when using, the tight head in top 5 top of 1 left end of lead screw is tight on other parts, and tight head in top 5 is that plastic materials makes, and is softer than other part materials, can not cause the damage to other parts, is equipped with anti-skidding line on the tight head in top 5 in addition, and frictional force is big when contacting with other parts, is equipped with reticulation annular knurl 3 on the rotating head 2, can be convenient for people twist rotating head 2 and lead screw 1, the utility model has the advantages of simple and reasonable structure, the tight frictional force in top is big during the use, and the protection effect is good, and the cost of manufacture is low, is fit for using widely.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
