Description

Technical Field

[0001] The utility model relates to the technical field of steel clips, in particular to a steel clip with pre-tightening force for preventing loosening. Background Art

[0002] ‌Rigid clamp refers to a connector used to fix steel pipes, also known as rigid clamps. Generally, most of them are composed of two sets of arc-shaped connectors, which can be connected by bolts. In this way, the pipe fittings can be connected and fixed. With the continuous development of technology, in order to meet different usage needs, ‌rigid clamps also appear in various shapes and different materials. The most common one is the traditional round shape. However, the existing rigid clamps still have some shortcomings. For example, they do not have the effect of buffering and pre-tightening, which leads to certain impacts during installation and connection. If the operation is improper, the rigid clamp will break or be damaged. Moreover, it cannot be quickly connected during connection and requires multiple adjustments and alignments. For this reason, we propose an anti-loosening rigid clamp with pre-tightening force. Utility Model Content

[0003] The purpose of the utility model is to provide a loose-proof steel clip with pre-tightening force to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

There are multiple groups of bottom springs, and the ends of the bottom springs away from the inner wall of the outer rigid card 2 are commonly connected with the inner rigid card 2. The inner wall of the outer rigid card 1 is provided with a matching groove 1 corresponding to the position of the top spring, and the inner wall of the outer rigid card 2 is provided with a matching groove 2 corresponding to the position of the bottom spring. A card block is vertically provided at the center of the end of the top of the fixed block 2 away from the outer rigid card 2, and a card groove matching the card block is provided at the center of the end of the bottom of the fixed block 1 away from the outer rigid card 1. The bottom of the outer wall of the card block is sleeved with a spring.

[0006] Furthermore: the bottom of the inner cavity of the slot is provided with a spring slot that matches the spring, and a conical connecting hole is provided between the top of the spring slot and the bottom of the inner cavity of the slot.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the anti-loosening steel clip with pre-tightening force is connected to the steel clip as a whole and the pipeline, the outer steel clip 2 is first placed at the bottom of the pipeline, and then the outer steel clip 1 is placed at the top of the pipeline. At this time, the fixing block 1 and the fixing block 2 on the left and right sides can be quickly aligned through the cooperation of the card block and the card slot, so that the bolts can be installed quickly, and the swinging and misalignment on the other side after the bolt on one side is installed can be avoided, thereby affecting the installation.
