[0002] At present, the steering gear clamp 1 is installed at the connection between the dust cover 2 and the housing, such as Figure 1 When installing, use a special tool to squeeze the Figure 2 The raised portion 11 of the large clamp 1 shown is tightened. After installation, a device is required to measure the width of the raised portion 11 to confirm whether the large clamp 1 is installed in place. When removing the large clamp 1, a hook-shaped tool is required to hook the gap between the large clamp 1 and the dust cover 2 to open the large clamp, thereby releasing the tightening.

[0003] The existing large clamp has the defect of being inconvenient to use, which is specifically reflected in the following aspects: 1. It is difficult for new engineers who have never been in contact with parts to start, and the installation equipment used needs to be able to output a clamping force of several thousand Newtons; 2. It is inconvenient for the client to disassemble and analyze the internal situation of the steering gear, and the client needs to spend extra time to provide disassembly instructions; 3. After the large clamp is disassembled after being squeezed and deformed, it will be directly scrapped due to the destruction of its shape, and it cannot be reused, which wastes raw materials and increases the experimental cost.

[0004] Therefore, it is necessary to design a portable steering gear clamp that can be installed and disassembled without special tools and can be reused. Summary of the invention

[0021] The utility model is now further described with reference to the accompanying drawings.

[0022] See also Figure 3The utility model is a portable steering gear clamp, comprising a large clamp body, a movable buckle, a bracket, and a positioning connection structure. An movable buckle 13 is respectively provided at both ends of the outer surface of the large clamp body 12, and the two movable buckles 13 are arranged in opposite directions. A bracket 14 is installed on the inner surface of the connecting end of the movable buckle 13 and the large clamp body 12. When the bracket 14 is opened, the movable buckle 13 bends outward, and the other end of the movable buckle 13 is separated from the large clamp body 12. Figure 4 When the bracket 14 is bent, the movable buckle 13 is attached to the outer surface of the large clamp body 12, and the other end of the movable buckle 13 is connected to the large clamp body 12 by a positioning connection structure.

[0023] The bracket 14 is in a herringbone structure, and the thickness at both ends of the herringbone structure is greater than the thickness in the middle, so that the herringbone structure can change between the open and bent states. The two ends of the herringbone structure are respectively connected to the movable buckle 13, and a gap is provided between the middle of the herringbone structure and the movable buckle 13.

[0024] See also Figure 5 The positioning connection structure includes a positioning boss 15 and a positioning groove 16, which are respectively arranged on the inner side of the other end of the movable buckle 13 and the outer surface of the large clamp body 12, and the positions of the positioning boss 15 and the positioning groove 16 correspond. Preferably, there are three positioning bosses 15 and three positioning grooves 16.

[0025] The large clamp body 12 is provided with an avoidance structure 17, which corresponds to the position of the bracket 14. The avoidance structure 17 is provided to provide an avoidance space for the bracket 14 to avoid interference when the movable buckle 13 is attached to the outer surface of the large clamp body 12. The avoidance structure 17 is a long strip through hole, and the size of the long strip through hole matches the size of the bracket 14.

[0026] The material of the large clamp body 12, the movable buckle 13 and the bracket 14 is mainly aluminum alloy, which has the advantages of high strength, lightness and good robustness.

[0027] See also Figure 3 In the initial state, the bracket 14 opens the movable buckle 13 so that the large clamp is in a free and relaxed state. When the large clamp 1 needs to be installed, the large clamp body 12 is placed outside the dust cover 2, and a pressing force is applied to the outer side of the end of the movable buckle 13. The movable buckle 13 presses down toward the large clamp body 12. After the bracket 14 passes through the avoidance structure 17, it contacts the dust cover 2. Under the action of the pressing force, the bracket 14 bends instantly, thereby driving the movable buckle 13 to adhere to the outer surface of the large clamp body 12 and achieve fastening. Figure 4 , Figure 6 shown.

[0028] When the large clamp 1 needs to be removed, it is only necessary to detent the two movable buckles 13 on the outside of the large clamp body 12 so that the bracket 14 is folded and then stretched out, thereby lifting the movable buckles 13 and placing the large clamp 1 in a free and relaxed state, and then the large clamp 1 can be removed from the dust cover 2.

[0029] The positioning boss 15 cooperates with the positioning groove 16 to determine whether the large clamp 1 is installed in place and in a locked state. After the large clamp 1 is closed, the cooperation state of the positioning boss 15 and the positioning groove 16 is as follows: Figure 5 shown.

[0030] After assembly, the large clamp 1 is mainly subjected to the force caused by the shaking of the shell in the vehicle and the compression and extension of the dust cover. However, since this force only acts on the inner side of the large clamp 1, it is impossible to open the movable buckle 13. To open the movable buckle 13, a certain force needs to be applied to the outer side of the large clamp 1. Since the steering gear is fixed in the vehicle and is almost not subjected to this force, the large clamp 1 can remain in a locked state during daily use of the vehicle, which is feasible.

[0031] The utility model realizes the change of the bending or attachment state of the movable buckle through the bracket, and the installation and disassembly of the large clamp can be completed without special tools, thereby improving the convenience of installation of the large clamp; the bracket and the positioning connection structure will not cause the large clamp to deform and can be reused, thus avoiding the waste of raw materials and reducing the experimental cost; by confirming whether the positioning connection structure is in a mating state, it can be judged whether the large clamp is installed in place, thereby improving the production line efficiency after mass production.
