Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure connectors, and in particular relates to a steel structure connector which is easy to install. Background Art

[0002] At present, steel structure engineering is a structure mainly made of steel, which is one of the main types of building structures. Steel structure is one of the more common structural forms in modern construction projects. The characteristics of steel are high strength, light weight, good overall rigidity and strong deformation ability. Therefore, it is particularly suitable for building large-span, super-high and super-heavy buildings. The material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can have large deformation, can withstand dynamic loads well, has a short construction period, and has a high degree of industrialization. It can be produced in a highly mechanized and specialized manner. Connectors are required to connect steel structures.

[0003] For example, the patent number is CN202020757363.0, and the patent name is a steel structure connector, including a connector, a first fixed block and a second fixed block arranged on the right side of the first fixed block are slidably connected to the upper surface of the connector. When in use, the first steel plate is placed at the center of the upper surface of the connector, and the first fixed block is pushed to the right. The sliding block at the bottom of the first fixed block moves to the right along the track of the first slide groove, so that the second through hole is aligned with the center of the first through hole, and the second fixed block is pushed to the left. The sliding block at the bottom of the second fixed block moves to the left along the first slide groove, so that the third through hole is aligned with the center of the first through hole. After inserting the threaded rod into the first through hole, the second through hole and the third through hole, the nut is rotated clockwise to the surface of the threaded rod so that the nut is against the first steel plate to complete the fixation.

[0004] However, in the process of using the above-mentioned solution, when fixing the first steel plate, it is still necessary to manually hold the nut and rotate it to the surface of the threaded rod, which may easily cause inconvenience during operation. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a steel structure connector that is easy to install. The fixing plate is clamped by a gasket and a clamping block, and the fixing plate clamps and fixes the steel plate, so that there is no need to manually screw the nut on the surface of the screw to fix it, which is convenient to use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel structure connector that is easy to install, comprising a connector body, wherein the top of the connector body is provided with two sliding grooves, the inside of the sliding groove is slidably connected with a sliding block, the top of the sliding block is fixedly connected with a fixing plate, the surface of the fixing plate is provided with two second through holes, the top of the connector body is provided with a clamping groove, the inside of the clamping groove is clamped with a steel plate, the surface of the steel plate is provided with two first through holes, the inside of the second through hole on the surface of the fixing plate on the left side is movably connected with a fixing cylinder, the inside of the fixing cylinder is threadedly connected with a screw, the inside of the fixing cylinder is fixedly connected with two springs, one end of the spring is fixedly connected with a fixing block, the surface of the fixing block is fixedly connected with a clamping block, and the clamping block movably passes through the fixing cylinder, one end of the screw is fixedly connected with a conical column, and the surface of the fixing cylinder is threadedly connected with a locking nut.

[0007] Furthermore, a gasket is fixedly connected to one end of the locking nut, and the slot is located between the two sliding slots.

[0008] Furthermore, one corner of the block is arranged in an arc shape.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. Press the fixed cylinder to prevent it from rotating, and then use a wrench to rotate the screw. The rotation of the screw drives the tapered column to move. The tapered column moves and contacts the surface of the block, squeezing the block out of the fixed cylinder. At this time, rotate the locking nut to move on the surface of the fixed cylinder. The locking nut drives the gasket to move. The gasket contacts the surface of the steel plate, and the fixed plate is clamped by the gasket and the block. The fixed plate clamps and fixes the steel plate, so there is no need to fix the nut on the surface of the screw by hand, which is convenient to use.

[0011] 2. When in use, insert the steel plate into the card slot for fixing, push the two fixing plates to move toward the steel plate, the fixing plates drive the slider to move inside the slide slot, and the fixing tube will pass through the first through hole and the second through hole on the surface of the fixing plate on the other side.
