Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a high-strength bolt. Background Art

[0002] The air conditioning compressor is an important part of automobile refrigeration. It plays the role of compressing and driving the refrigerant in the air conditioning refrigerant circuit. The air conditioning compressor is generally installed in the outdoor unit. The air conditioning compressor extracts the refrigerant from the low-pressure area and sends it to the high-pressure area for cooling and condensation after compression. The heat is dissipated into the air through the heat sink. The refrigerant also changes from gas to liquid, and the pressure increases. Bolts are needed when using the compressor for automobile air conditioning to fix the compressor.

[0003] The Chinese patent with the relevant patent publication number: CN215567149U discloses a high-strength bolt for an automobile air-conditioning compressor. The ring disk has connecting ribs and C-shaped ribs to connect and reinforce the ring disk and the bare rod. At the same time, the outer side of the C-shaped rib has an L-shaped connecting block connected to the screw head. With the help of the curing connection of the curing mechanism, the bare rod behind the screw and the screw head are well reinforced and not easy to break.

[0004] The bolts in the above-mentioned prior art become loose due to wear after long-term use, causing the air-conditioning compressor to loosen and affecting its use. In addition, the bolts in the application are not provided with a reinforcement structure, the overall strength is poor, and they are prone to bending under the action of external force. For this reason, we propose a high-strength bolt. Utility Model Content

[0005] In view of the above problems, the utility model provides a high-strength bolt, which can make the bottom of the bottom ring fit tightly against the object, increase the friction between the bolt and the object under the reaction force of the spring, prevent the bolt from loosening during use, and ensure the stability of the automobile air-conditioning compressor when it is fixed.

[0007] In a further technical solution, a hexagonal hole is opened at the bottom of the bolt body, and the hexagonal reinforcement column is fixedly connected to the inner side of the hexagonal hole.

[0008] In a further technical solution, a sliding rod is fixedly connected to the top of the movable ring, a penetrating sliding hole is opened on the top of the bolt body, and the top end of the sliding rod penetrates the sliding hole and is slidably connected to the inner side of the sliding hole.

[0009] In a further technical solution, a top ring is fixedly connected to the top of the sliding rod, and the top of the top ring fits tightly with the bottom of the internal threaded ring.

[0010] In a further technical solution, an anti-skid groove is provided on the outer side of the internal thread ring, and the anti-skid groove is distributed in a ring shape on the outer side of the internal thread ring.

[0011] In a further technical solution, an anti-sliding block is fixedly connected to the bottom of the bottom ring, and the anti-sliding block is distributed in a ring shape at the bottom of the bottom ring.

[0012] In a further technical solution, a hexagonal groove is provided on the top of the bolt body, and the hexagonal groove is located on the inner side of the external threaded tube.

[0013] The beneficial effects of the utility model are:
