Description

Gear drive external screw thread spare

Technical Field

The utility model relates to a screw member technical field specifically is a gear drive external screw thread spare.

Background

The existing external thread element driven by the gear is generally of an integral connection structure, so that the external thread element can be controlled to rotate under the rotation of the gear, the effect of use needs is achieved, but the integral replacement is needed when the gear or the thread element is worn and cannot be used, and the use cost is high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a gear drive external screw thread spare to the current external screw thread spare through gear drive that proposes in solving above-mentioned background art generally all is overall connection structure, can control external screw thread spare and rotate under gear revolve like this, reaches the effect that needs of using, but such setting need whole change when gear or screw thread spare loss appear and can't use, has caused the problem that use cost is big.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a gear drive external screw thread spare, includes the gear, the fixed connecting block that is provided with in right side of gear, the spread groove has been seted up on the right flank of connecting block, the internally mounted of spread groove has the fixed block, the fixed threaded rod that is provided with in right flank of fixed block, all set up threaded hole on the lateral wall of connecting block and fixed block laminating, the internally mounted of screw hole has the screw.

Preferably, the cross section of the fixing block is square.

Preferably, the screw is a hexagonal screw.

Preferably, the inner wall of the connecting groove is provided with a sealing gasket in an attaching mode.

Preferably, a butt joint block is fixedly arranged on the left side wall of the gear.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses simple structure at first can make threaded rod and gear butt joint through the cooperation of connecting block, spread groove and fixed block, through the position that the combination of screw hole and screw can fixed connection to this reaches dismantled and assembled separation's effect, can change alone when the condition that can't use appears in gear or threaded rod under this kind of mode, reduces use cost.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the 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 efforts all belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being 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.

The embodiment is as follows:

referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a gear drive external screw thread spare, includes gear 1, the fixed connecting block 2 that is provided with in right side of gear 1, spread groove 3 has been seted up on the right flank of connecting block 2, the internally mounted of spread groove 3 has fixed block 4, can restrict the position of fixed block 4 installation through spread groove 3, the fixed threaded rod 5 that is provided with in right flank of fixed block 4, threaded hole 6 has all been seted up on the lateral wall of connecting block 2 and the 4 laminating of fixed block, the internally mounted of threaded hole 6 has screw 7, and threaded hole 6 and screw 7 combine the mounted position that can fixed threaded rod 5, make it combine as whole with gear 1.

Wherein, the cross-section of fixed block 4 is square, and is square to have good limiting displacement, can restrict the position that fixed block 4 installed, screw 7 is the hexagonal screw, and the hexagonal screw makes things convenient for the dismouting, the inner wall subsides of spread groove 3 are equipped with seal gasket, strengthen the compactness of butt joint, the fixed butt joint piece 8 that is provided with on the left side wall of gear 1 makes things convenient for gear 1 and installation position butt joint.

The working principle is as follows: at first threaded rod 5 can insert in connecting groove 3 of connecting block 2 through fixed block 4, can combine with gear 1 with this, the setting of square fixed block 4 can reach spacing effect of connecting, make things convenient for screw hole 6 positions to align like this, save the step of adjusting, can accomplish fixed equipment operation under screw 7's connection, reach dismantled and assembled effect with this, can change alone when gear 1 or threaded rod 5 appear damaging unable use like this, avoid the whole problem that changes and cause high cost.

Having shown and described the basic principles and principal features of the invention and advantages thereof, it will be apparent to those skilled in the art that the invention is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof; 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, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
