Technical Field

The invention relates to the field of nut quick tighteners, in particular to a nut quick tightener suitable for a long screw.

Background

In the processes of product assembly, interior decoration, building construction and the like, a long screw is required to be used in certain scenes, and a nut on the long screw is required to be installed and fastened during assembly. A problem also arises that the long screw usually has a large number of turns of thread, and needs to be rotated many times in the nut tightening process, and a common nut tightener (electric wrench) is not suitable for the situation, and people can only assemble and tighten manually, and the process is complicated.

Disclosure of Invention

The invention aims to solve the problems that: the utility model provides a nut is fast to be taken up suitable for long rod screw can be electronic installs the fastening and lift off to nut on the long rod screw to solve the problem that current long rod nut can only rely on manually to assemble

The invention is realized by the following technical scheme:

a nut quick tightener suitable for long screw rod which characterized in that: the device comprises a shell module, a transmission module and a motor module; the shell module is a cavity structure consisting of a lower shell of the positioning gear and an upper shell wrapping the internal structure, and the positioning part of the driven wheel is hollowed out so as to meet the requirement that a long screw rod can penetrate through the positioning part when the nut is tightened; the transmission module is a gear transmission mechanism consisting of two gears and two bearings, one of the gears is a driving wheel and the other is a driven wheel, the driving wheel and the driven wheel are mutually meshed, the inner ring of the bearing is welded with the gear in the vertical direction, the outer ring of the bearing is fixed on the shell, and the inner ring of the bearing connected with the driven wheel is provided with a hexagonal groove which can be matched with a nut; a motor in the motor module drives the driving wheel to rotate, and the bearing inner ring connected with the driven wheel is driven to rotate through the transmission module so as to drive the nut to rotate.

Furthermore, the bearing inner ring connected with the driven wheel is provided with a hexagonal groove

Further, the housing cavity is hollowed out at the position where the driven wheel is positioned.

The invention has the beneficial effects that: the through hole is designed to meet the requirement that the nut on the long screw rod can pass through the through hole to the tail end in the tightening process. And provides power to solve the problems of cumbersome fastening process and the common nut tightener (electric wrench) not suitable.

Detailed Description

The invention is further illustrated with reference to the following specific examples and the accompanying drawings.

As shown in fig. 1-3, a nut runner for a long screw comprises a housing module 1, a motor module 2 and a transmission module 3 which can be separated from each other. The shell module 1 is composed of an upper shell 11, a lower shell 12 and a cavity-shaped structure; the upper case 11 has a motor switch 111, a charging plug 114, and a through hole 112, and the lower case 12 has a through hole 113; the housing module 1 serves for fixing the outer bearing and for wrapping the inner structure. The motor module 2 consists of a motor 21 and a transmission shaft 22; the motor module 2 functions to provide a rotational force. The transmission module 3 is composed of a driven wheel part 31 and a driving wheel part 32, the driven wheel part 31 is composed of a driven wheel 311 and a first bearing 312, the driven wheel 311 is provided with a circular through hole 3111, the first bearing 312 is provided with a hexagonal first bearing through hole 3121, and the driving wheel part 32 is composed of a driving wheel 321 and a second bearing 322.

After the motor switch 111 is turned on, the motor 21 starts to operate, the transmission rotating shaft 22 drives the driving wheel 321 to rotate, the driving wheel 321 drives the driven wheel 311 to rotate, and the bearing through hole 3121 connected with the driven wheel starts to rotate, so as to drive the nut to rotate.

The outer bearings of the first bearing 312 and the second bearing 322 are connected with the lower shell 12 through a snap connection to keep relative static.

The upper case through hole 112, the driven wheel through hole 3111, the bearing through hole 3121 and the lower case through hole 113 penetrate from top to bottom, so that the long pole screw can pass therethrough.

The nut tightener suitable for the long screw is designed to solve the problem that the nut on the long screw is time-consuming and labor-consuming in the screwing-in or screwing-out process.

The above embodiments are merely preferred embodiments of the present invention, which are intended to be illustrative and not limiting, and any changes, substitutions, combinations, simplifications, modifications, etc. made by those skilled in the art without departing from the spirit and principle of the present invention shall be included in the scope of the present invention.
