Description

Bolt tightening device

Technical Field

The utility model relates to a universal tool field especially relates to a bolt tightening device.

Background

Generally, bolt tightening is relatively simple and the tools used are of different forms. The common tools such as a shifting wrench, a chain wrench and the like are applied in different forms. However, the form of the bolt is different from the form of the bolt, namely the bolt is loosened or screwed by utilizing the limit bolt at the front part of the wrench and the rear part of the wrench by utilizing the lever principle. This method is not suitable for all the bolts in the used positions, and special situations are more, for example, the bolts are arranged on the bottom surface of the equipment and are shielded by objects, and the wrench handle has no rotating space. The most common conveying water pipes such as various basins are generally arranged at the back of the interior of the cabinet and are shielded by the basins, and a conventional long-handle type wrench is difficult to stretch into the cabinet for operation. In addition, the nut of part of the bolt is easily ground flat due to repeated screwing of the angular position, and the existing wrench is very easy to slip when facing the nut.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art weak point, provide a simple structure, convenient to use, the suitability is strong, can both provide the bolt tightening device of effective support to the bolt loading and unloading of special position.

The equipment comprises a supporting pipe, wherein the main supporting pipe is a main body supporting part of the equipment, is positioned on the side wall of the supporting pipe, and is fixedly provided with a holding handle perpendicular to the supporting pipe.

The supporting tube is internally and rotatably provided with a core rod, and the core rod is rotatably arranged in the supporting tube through a bearing.

The top of the core rod is transitionally provided with a bolt fixing square frame, namely a circular tube transition square tube form which is integrally connected between the core rod and the bolt fixing square frame. The bolt fixing frame is in a square frame form, a bolt penetrates through the side edge of the bolt fixing frame, and a flat plate is fixedly arranged at the tail end of the bolt.

The bottom of the core bar is provided with a rotating handle in a penetrating way, and the setting direction of the rotating handle is vertical to the core bar.

Furthermore, two ends of the rotating handle are provided with limiting heads. Preventing the rotating handle from being pulled out.

The utility model discloses during the use, move the bolt through twisting, adjust the interval between dull and stereotyped and the bolt fastening square frame, also be exactly to different bolt models, make the interior border of dull and stereotyped and bolt fastening square frame entangle and press from both sides tight nut, hold on one hand and hold the handle, then twist and move the turning handle, in the face of narrow environment, during the bolt of corner position, can twist in turn and move the handle, make it only rotate 180 degrees, 90 degrees or less angles even, accomplish the dismantlement and the installation of bolt. The basin water pipe bolt fastening operation is taken as an example, the whole equipment extends into the rear part of the basin, the flat plate and the fixed square frame clamp nut are enabled, then the handle is held by one hand to enable the relative position of the equipment to be fixed, the handle is alternatively screwed by the other hand, namely, the handle is rotated 180 degrees, and then the handle is translated to the other side from one side of the core rod. And alternately screwing. Simultaneously, the nut of part bolt is because twist its edges and corners position is ground very easily repeatedly, and the slippage is very easy when conventional spanner faces this kind of nut, can only cut the processing, seriously influences work efficiency, verifies through actual operation, and the fixed form of this equipment flat board plus fixed square frame can realize further fastening through hard spacing to this kind of bolt equally, effectively demolishs this kind of bolt.

The beneficial effects of the utility model are that, the utility model discloses simple structure, convenient to use, low in cost and easy maintenance. The convenient loading and unloading of bolt of multi-angle has been realized through simple structure. For the bottom surface of equipment, bolts which are inconvenient to operate by using a conventional wrench, such as seriously worn nuts, can be disassembled and assembled in an alternate screwing mode after being sleeved. Great convenience is provided for loading and unloading work.

Detailed Description

Referring to fig. 1 and 2, a bolt tightening device of the present invention includes a supporting tube 6, the main supporting tube is a main supporting part of the present device, and is located on the side wall of the supporting tube 6, and a grip handle 3 perpendicular to the supporting tube 6 is fixedly disposed.

The core rod 4 is rotatably arranged in the supporting tube 6, and the core rod 4 is rotatably arranged in the supporting tube 6 through a bearing 7.

The top of the core rod 4 is transitionally provided with a bolt fixing square frame 1, namely, the core rod 4 and the bolt fixing square frame 1 are connected into a whole in a circular tube transition square tube mode. The bolt fixing frame 1 is in a square frame form, a bolt 2 penetrates through the side edge of the bolt fixing frame 1, and a flat plate 8 is fixedly arranged at the tail end of the bolt 2.

The bottom of the core bar 4 is provided with a rotating handle 5 in a penetrating way, and the rotating handle 5 is arranged in a direction vertical to the core bar 4.

Furthermore, two ends of the rotating handle 5 are provided with limiting heads. Preventing the turning handle 5 from coming off.

The utility model discloses during the use, move bolt 2 through twisting, adjust the interval between dull and stereotyped 8 and the bolt fastening square frame 1, also be exactly to different bolt models, make dull and stereotyped 8 and bolt fastening square frame 1 interior border entangle and press from both sides tight nut, hold handle 3 on one hand, then twist and move turning handle 5, in the face of narrow environment, during the bolt of corner position, can twist in turn and move the handle, make it only rotate 180 degrees, 90 degrees or less angles even, accomplish the dismantlement and the installation of bolt 2. By taking an example of the basin water pipe bolt fastening operation, the whole device is stretched into the rear part of the basin, the flat plate 8 and the fixed square frame 1 clamp a nut, then the handle 3 is held by one hand to fix the relative position of the device, the handle 5 is alternately screwed by the other hand, namely, the handle 5 is rotated 180 degrees, and then the handle 5 is translated to the other side from one side of the core rod 4. And alternately screwing. Simultaneously, the nut of part bolt is because twist its edges and corners position is ground very easily repeatedly, and the slippage is very easy when conventional spanner faces this kind of nut, can only cut the processing, seriously influences work efficiency, verifies through actual operation, and the fixed form that this equipment flat board 8 consolidates fixed square frame 1 can realize further fastening through hard spacing to this kind of bolt equally, effectively demolishs this kind of bolt.
