Description

Technical Field

[0001] The utility model specifically relates to the technical field of rail fasteners, in particular to a rail fastener with a shock-absorbing effect. Background Art

[0002] Slide rails, also known as guide rails or runners, are hardware components fixed to the cabinet body of furniture to allow drawers or panels to move in and out. Slide rails are suitable for connecting wooden and steel drawers in cabinets, furniture, document cabinets, bathroom cabinets, and other furniture. Slide rails come in two types: those for furniture and household hardware, and oversized industrial rails. These rails have a higher load-bearing capacity and are used in industrial applications such as modified vehicles, RVs, cabinets, and fire trucks.

[0003] Tracks are commonly used devices in industrial construction, enabling various equipment to move smoothly. However, when the equipment on the track moves too fast, the weight of the equipment changes, or the equipment is impacted by movement, the bearing pressure of the track will suddenly increase, causing the various components of the track to squeeze each other or collide with each other, resulting in greater wear. Long-term wear will seriously affect the normal use of the track. Utility Model Content

[0004] The purpose of the present utility model is to provide a track fastener with a shock-absorbing effect. The multiple connecting components on the track are provided with multiple springs, which can buffer and eliminate the impact on the track, so as to solve the technical problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A rail fastener with a shock-absorbing effect comprises an upper fastener and a connecting assembly, wherein a lower fastener is provided below the concave-shaped upper fastener, and the upper fastener is located inside the lower fastener;

[0007] There are multiple connecting components for connecting the upper layer buckle and the lower layer buckle, and the multiple connecting components have the same structure; the multiple connecting components are respectively located at both ends of the upper layer buckle and the lower layer buckle;

[0008] The connecting assembly includes a screw rod, a nut is welded on the top of the screw rod, a nut is threadedly connected to the outside of the screw rod, and the nut is located at the bottom of the lower layer fastener; the upper end of the screw rod is sleeved with an upper layer spring, and the lower end of the screw rod is sleeved with a lower layer spring; the upper layer spring is located between the upper layer fastener and the lower layer fastener, and the lower layer spring is located below the nut.

[0009] As a further technical solution of the present invention, the upper layer fastener includes an upper layer fastener body, which is concave in shape; a plurality of upper layer positioning holes are provided at both ends of the upper layer fastener body.

[0010] As a further technical solution of the present invention, the lower layer buckle comprises a lower layer buckle body, which is concave in shape; a plurality of lower layer positioning holes are provided at both ends of the lower layer buckle body;

[0011] Furthermore, the sizes of the multiple lower-layer positioning holes are the same as the sizes of the multiple upper-layer positioning holes, and the positions of the multiple lower-layer positioning holes correspond to the positions of the multiple upper-layer positioning holes respectively; the multiple connecting components are respectively located in the multiple upper-layer positioning holes and the lower-layer positioning holes.

[0012] As a further technical solution of the present invention, the bottom of the connecting assembly is threadedly connected to the base, and the base is located below the lower layer of fasteners.

[0013] As a further technical solution of the present invention, the length of the upper layer fastener is greater than the length of the lower layer fastener; the width of the upper layer fastener is smaller than the width of the lower layer fastener.

When the utility model is used, the multiple connecting components are respectively placed in the multiple upper positioning holes of the upper fastener, and then the multiple connecting components fix the upper fastener and the lower fastener, and the multiple connecting components are respectively located at both ends of the upper fastener and the lower fastener, which can increase the stability of the connection between the upper fastener and the lower fastener, and prevent the upper fastener and the lower fastener from displacement; the bottoms of the multiple connecting components are respectively fixedly connected to the multiple bases, which can increase the stability of the connecting components, thereby further increasing the connection stability of the connecting components to the upper fastener and the lower fastener;

[0016] 2. In the present invention, the upper springs on the multiple connecting components are all located between the upper fasteners and the lower fasteners. When the equipment on the track moves quickly or the weight changes greatly, the equipment will cause a large impact force on the track. At this time, the elastic force generated by the multiple upper springs can reduce the impact force of the upper fastener on the lower fastener, prevent the upper fastener and the lower fastener from colliding, and ensure that the upper fastener and the lower fastener will not be damaged due to collision with each other; in addition, the multiple lower springs at the bottom of the lower fastener play the role of supporting the lower fastener, increasing the bearing capacity of the lower fastener, and can also buffer the descending speed of the lower fastener, preventing the lower fastener from colliding with the components below it.
