Description

A quick fastening device for hexagon socket bolts

technical field

The utility model relates to a bolt fastening device, in particular to a fastening device for inner hexagonal bolts, and belongs to the field of electric equipment installation tools.

Background technique

When the air switch in the switch cabinet and the magnetic card meter box contactor are connected to the incoming and outgoing wire terminals and the incoming and outgoing cable terminals, many places need to use inner angle bolts to fasten the connection. Affected by the surrounding environment, the installation space is particularly narrow. Just increased operational difficulty. The ordinary hexagonal wrench currently available on the market cannot be put in from above the hexagonal bolt to be tightened at all, especially the fastening of some hexagonal bolts requires the use of pliers or ordinary hexagonal wrench plus an auxiliary operation to complete the operation Tightening the connection increases the difficulty of operation for the staff.

Utility model content

The purpose of the utility model is to provide a fast fastening device for hexagon socket bolts with simple structure and convenient use, which reduces the labor intensity of workers and improves work efficiency.

Problem described in the utility model is realized with following technical scheme:

A fast fastening device for hexagon socket bolts, which includes a sleeve rod connected with the hexagon socket bolt and a torque wrench for axially screwing in the sleeve rod, the torque wrench is vertically mounted on the sleeve rod, and the sleeve rod It includes a straight rod-shaped connecting rod, a plug joint for inserting hexagon socket bolts and a conversion block matched with a torque wrench. Matched, the conversion block is fixedly installed on the upper part of the connecting rod, and the conversion block is matched with the torque wrench.

In the quick fastening device for the hexagon socket head bolt, the plug joint and the connecting rod are detachably connected.

A further improvement of the above-mentioned quick fastening device for hexagon socket head bolts is that there are multiple conversion blocks, and each conversion block is a hexagonal prism with different side lengths.

A further improvement of the above-mentioned quick fastening device for hexagon socket head bolts is that a handle is provided on the top end of the connecting rod for easy gripping.

The beneficial effects of the utility model are:

The utility model has the advantages of simple structure, convenient use and time-saving and labor-saving. When in use, the bottom end of the sleeve rod is abutted against the countersunk hole of the hexagon socket bolt, and the torque wrench is rotated on the upper part of the sleeve rod to drive the sleeve rod to drive the hexagon socket bolt downward to tighten, and the tightening of the hexagon socket bolt is completed. The phenomenon of hand injury caused by direct auxiliary fastening by the staff is avoided, and the effect of fast fastening the bolts is achieved.

The utility model is used to fasten the inlet and outlet wire terminals and the inlet and outlet cable terminals of the air switch to prevent the hands of the staff from being scratched when fastening the hexagon socket bolts, so that the magnetic card meter box contactor or the air switch in the switch cabinet can enter and exit Reliable connection between wire terminals and incoming and outgoing cable terminals.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is a structural representation of the utility model;

The list of labels in the figure is: 1. Torque wrench, 2. Sleeve rod, 2-1. Connecting rod, 2-2. Plug connector, 2-3. Conversion block, 2-4. Handle, 3. Hexagon socket head bolt, 4. Table box.

Detailed ways

A fast fastening device for hexagon socket head bolts, the structure is shown in Figure 1 and Figure 2, it includes a torque wrench 1 and a sleeve rod 2, the torque wrench 1 is vertically mounted on the upper part of the sleeve rod 2. Refer to Fig. 1 for the assembly state when the utility model is in use. Due to the limited installation space in the meter box 4, it is more difficult for the staff to fasten the hexagon socket bolt 3 with a common Allen wrench. During the tightening operation, the bottom end of the sleeve rod 2 is plugged into the top of the hexagon socket head bolt, and the torque wrench 1 is vertically worn on the upper part of the sleeve rod 2, with the sleeve rod 2 as the axis, by rotating the torque wrench 1 To realize the axial screwing of the sleeve rod, so that the sleeve rod 2 drives the hexagon socket head bolt 3 to be screwed down to realize fast fastening.

The structure of the sleeve rod 2 is shown in FIG. 2 , including a connecting rod 2-1, a plug joint 2-2, a conversion block 2-3 and a handle 2-4. The connecting rod 2-1 is a straight rod, and the bottom end of the connecting rod 2-1 is connected with a plug connector 2-2, and one end of the plug connector 2-2 is matched with the countersunk hole of the hexagon socket bolt 3 for The plug fits the inner hexagon bolt, and the other end is connected with the connecting rod 2-1. In order to adapt to different sizes of hexagon socket bolts, the connection ends of the plug joint 2-2 and the connecting rod 2-1 can be connected in different ways for easy disassembly such as plug-in, clamping or threaded connection. When the size of the socket head bolts is different, A suitable plug connector can be selected for the tightening operation.

The conversion block 2-3 is worn and fixed on the top of the connecting rod 2-1, and the conversion block 2-3 is matched with the torque wrench 1. Multiple conversion blocks 2-3 can be provided. In this embodiment, there are three conversion blocks 2-3 in total. Each conversion block 2-3 is a hexagonal prism with different side lengths, which is suitable for torque wrenches 1 of different sizes. It is also possible to set only one conversion block 2-3, and set this conversion block 2-3 as a special-shaped prism with unequal side lengths.

The handle 2-4 is arranged on the top of the connecting rod 2-1, which is convenient for the staff to hold the sleeve rod 2 during operation.

The torque wrench 1 is matched with the conversion block 2-3 of the sleeve rod 2. The torque wrench 1 is a long strip plate, and a through hole is arranged at one end of the torque wrench 1, and the through hole cooperates with the conversion block 2-3. It is also possible to make the shape of the conversion block 2-3 into the shape of a standard nut. At this time, the torque wrench 1 can be a commercially available common wrench.
