Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a snap nut hook. Background Art

[0002] When a U-shaped steel is fixedly connected to an external object, a fastener is required for connection. Refer to Figure 1 , the fasteners of the prior art include a bracket and fastener components. A set of fastener components includes a hexagon bolt, a hexagon nut, two flat washers and a spring washer. In order to improve the construction efficiency, the bracket has been pre-assembled in the factory. However, in the actual construction site, due to environmental differences and size matching problems, the pre-assembled bracket is often difficult to fit perfectly, which requires the construction personnel to disassemble and reassemble the fastener components to meet different installation requirements.

[0003] The prior art limits the versatility of the fastener, making the installation in different scenarios cumbersome, and also increasing the risk of loss of fastener accessories. Small parts such as bolts and nuts are easily dropped during the disassembly process, resulting in unnecessary waste of materials. In addition, the disassembly and reassembly process prolongs the installation time and reduces the overall construction efficiency.

[0004] Therefore, the applicant intends to propose a snap nut hook to solve the above problems. Summary of the Utility Model

[0008] One end of the bracket is provided with a chute, and the snap nut is slidably arranged in the chute of the bracket through the clamping portion. The bolt passes through a through hole on the U-shaped steel and cooperates with the threaded through hole of the snap nut to lock and fix the U-shaped steel on the bracket. The other end of the bracket is provided with a connecting portion for fixedly connecting an external object.

[0009] Further, the bracket includes two first brackets and several second brackets; the two first brackets are fixedly connected by several second brackets.

[0010] Further, one end of the first bracket is provided with a chute, the other end of the first bracket is provided with a connecting portion, both ends of the second bracket are provided with chutes, the connecting portion of one of the first brackets is fixedly connected to the chute at one end of the second bracket through a fastener, the chutes of several second brackets are fixedly connected through fasteners, the chute of the other first bracket is fixedly connected to the chute of the second bracket through a fastener, and the connecting portion of the other first bracket is fixedly connected to an external object.

[0011] Further, it further includes several positioning members. The positioning member includes a positioning bottom plate and a positioning portion. The positioning bottom plate is provided with through holes for fasteners to pass through. Two opposite sides of the positioning bottom plate extend in a direction perpendicular to the positioning bottom plate to form the positioning portion. The positioning member is arranged at the joints of the first bracket and the second bracket and between the second brackets.

[0012] Further, the first bracket includes a first arm and a second arm. The included angle between the first support arm and the second support arm is less than 180°. A chute is formed on the first arm, and a connecting portion is provided on the second arm. The second bracket includes a third arm, a fourth arm, and a fifth arm.

[0013] Further, the clamping portion is a pair of U-shaped thin shell grooves with opposite bottoms.

[0014] Further, the clamping portion is a pair of L-shaped bending members that extend vertically upward and then fold away from the threaded through hole.

[0015] Further, the nut body is a cuboid, the chute is a racetrack-shaped through hole, and the width of the nut body is smaller than the width of the chute.

[0016] Further, the connecting portion is provided with one through hole or several through holes.

[0017] After adopting the above scheme, the gain effect of the present utility model is as follows: When the size of the construction environment does not match the pre-assembled bracket, the U-shaped steel can be driven by the snap nut to slide along the chute of the bracket and adjusted to the required position. Subsequently, the U-shaped steel is locked and fixed on the bracket. During this process, the clamping portion of the snap nut is clamped in the chute of the bracket. At the same time, the clamping portion can slide smoothly in the chute, ensuring that the snap nut will not fall off or be lost during the adjustment process. The present utility model not only has general adaptability but also effectively prevents the loss of components, thereby improving the construction efficiency. Description of the Drawings
