Finally, ensure that the fastener (3) is completely connected with the U-shaped connecting rod (1) and the O-shaped connecting rod (2).

Description

A cross-shaped universal hinge connection device

technical field

The utility model relates to a universal hinge, in particular to a cross-shaped universal hinge connecting device.

Background technique

In the static test, the force needs to act in a specific direction. In order to achieve this purpose, it is necessary to manufacture corresponding parts to achieve direction control. However, at this stage, for different test requirements, it is necessary to manufacture corresponding control direction parts, and these parts are not reusable. Different static tests need to manufacture different parts, which is time-consuming and laborious, which increases the manufacturing cost and prolongs the The test period is shortened, resulting in waste.

Contents of the invention

The purpose of this utility model is to provide a cross-shaped universal hinge connection device capable of adjusting any angle.

The technical scheme of the utility model: the connecting device includes a U-shaped connecting rod 1, an O-shaped connecting rod 2 and a bolt 3, the front end of the U-shaped connecting rod 1 is U-shaped, and the There are screw holes at the interface, which are fixed by bolts 3.

As an improvement of the technical solution, the diameters of the screw holes on the two lugs of the U-shaped interface are different.

The beneficial effects of the utility model: in the design stage of the static test tooling, the steel plate design work for controlling the direction of the force line can be omitted. Choose this unit for its versatility. During the test, first connect the U-shaped connecting rod 1 to the fixing device, adjust the opening direction of the U-shaped mouth of the U-shaped connecting rod 1, and connect the U-shaped connecting rod 1 completely. Then connect the O-shaped connecting rod 2 to the U-shaped connecting rod 1 through the fastener 3, so as to ensure that the O-shaped connecting rod 3 can rotate around the fastener 3, and rotate the O-shaped connecting rod 3 to obtain the direction of the required line of force. Finally, ensure that the fastener 3 is completely connected with the U-shaped connecting rod 1 and the O-shaped connecting rod 2 .

Among the figure: 1 is a U-shaped connecting rod, 2 is an O-shaped connecting rod, and 3 is a fastener.

Detailed ways

The technical solution will be further described in detail below in conjunction with the accompanying drawings.

The invention relates to a cross-shaped universal hinge connecting device. The structure is mainly composed of a U-shaped connecting rod 1, an O-shaped connecting rod 2 and a fastener 3.

U-shaped connecting rod 1, its structure is the U-shaped end of columnar connection. Drill holes (4,5) on the upper and lower sides of the U-shaped end respectively. In order to increase friction, the diameters of the holes are different. There are threads at the cylindrical structure, and the U-shaped connecting rod 1 is connected through the thread at the cylindrical place and a force applying device, such as a loading device in a static test as a moving cylinder.

The O-shaped connecting rod 2 is structured as an O-shaped end connected in a cylindrical shape. The O-end is open and the cylindrical end is threaded. The O-shaped connecting rod and the fixing device are connected by threads.

Fastener 3 consists of special bolts and nuts (Figure 3). Wherein the bolt is a variable diameter, and the diameter is matched with the size of the hole at the U-shaped connecting rod 1 place to make.

During the test, first connect the U-shaped connecting rod 1 to the fixing device, adjust the opening direction of the U-shaped mouth of the U-shaped connecting rod 1, and connect the U-shaped connecting rod 1 completely. Then connect the O-shaped connecting rod 2 to the U-shaped connecting rod 1 through the fastener 3, so as to ensure that the O-shaped connecting rod 3 can rotate around the fastener 3, and rotate the O-shaped connecting rod 3 to obtain the direction of the required line of force. Finally, ensure that the fastener 3 is completely connected with the U-shaped connecting rod 1 and the O-shaped connecting rod 2 .

Claims (2)
