Detailed Description

The utility model will now be described in detail with reference to the drawings and specific examples. The present embodiment is implemented on the premise of the technical scheme of the present utility model, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present utility model is not limited to the following examples.

The utility model provides a pre-mounting metal bracket, which comprises a mounting part 1 provided with a mounting hole 2 and an arc-shaped sheet 3 connected with one end of the mounting part 1, wherein a plurality of metal claws 4 which are rotationally symmetrically distributed by taking the center of the mounting hole 2 as a rotational symmetry center are arranged in the mounting hole 2, the metal claws 4 are hexahedrons, the bottom surfaces of the metal claws 4 are connected with the inner wall of the mounting hole 2, gaps are reserved between two adjacent side surfaces of adjacent metal claws 4, the metal claws 4 protrude towards the inner side of the bracket, and the top surfaces of the metal claws 4 are not contacted with each other.

The gap between the adjacent two sides of the metal claw 4 contributes to a reduction of stress. The metal claws 4 are distributed in a rotationally symmetrical manner, so that the stress can be uniformly reduced, and the strength of the metal claws 4 is improved.

When the pre-mounting metal bracket is used, the bolts are inserted into holes formed on the top surfaces of the metal claws 4 of the mounting holes 2 in the protruding direction of the metal claws 4, the plurality of metal claws 4 on the mounting holes 2 clamp the threads of the bolts, and the bolts are fixed to prevent the bolts from falling off.

The side of the metal claw 4 facing the outer side of the metal bracket is an outer side surface, the other side opposite to the outer side surface is an inner side surface, and the included angle between the inner side surface of the metal claw 4 and the inner side surface of the mounting part 1 is 120-145 degrees. The angle between the inner side of the metal claw 4 and the inner side of the mounting portion 1 is related to the strength of the metal bracket and the size of the bolt, and if the angle between the inner side of the metal claw 4 and the inner side of the mounting portion 1 is too large, the hole formed on the top surface of each metal claw 4 is too small to be suitable for large bolts. If the angle between the inner side of the metal claw 4 and the inner side of the mounting portion 1 is too small, especially if the angle exceeds 90 degrees, the metal claw 4 at this time completely loses the effect of seizing the screw thread of the bolt, so the angle cannot be too small. If the included angle is close to and larger than 90 degrees, the effect of the metal claw 4 clamping the small bolt threads is poor, and the metal claw is suitable for large bolts. The metal claw 4 is suitable for most common bolts when the included angle between the inner side surface of the metal claw and the inner side surface of the mounting part 1 is 120-145 degrees.

In some embodiments, the inner side of the metal jaw 4 is at an angle of 125 degrees to the mounting portion 1.

In some embodiments, the inner side of the metal jaw 4 is at an angle of 130 degrees to the mounting portion 1.

In some embodiments, the inner side of the metal jaw 4 is at an angle of 140 degrees to the mounting portion 1.

The angle between the inner side surface of the metal claw 4 and the mounting portion 1 in the above three embodiments is suitable for most common bolts.

In some embodiments, the metal jaw 4 is a curved hexahedron. The outer and inner sides of the metal claw 4 are shaped as sector rings. When the shape of the outer side surface and the inner side surface of the metal claw 4 is a fan ring, the contact of the bolt and the metal claw 4 is more fit, and the accurate installation position of the bolt is ensured.

The number of metal claws 4 is plural and may be 4 or 6 or 8 or 10.

The junction of the mounting part 1 and the arc-shaped piece 3 is provided with a fixed plate 5, the connection between the mounting part 1 and the arc-shaped piece 3 is strengthened, and the integral strength of the metal claw 4 is strengthened.

According to the utility model, the screw thread of the bolt is clamped by the metal claw 4, so that the pre-installation of the bolt is realized, an operator does not need to use one hand for fixing and then use the other hand for installing when installing the metal bracket, an additional person is not required for helping to fix, the operator inserts the bolt into the metal claw 4, and the bolt can be installed by one hand after clamping the bolt, so that time and labor are saved.

The foregoing describes in detail preferred embodiments of the present utility model. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the utility model by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
