Description

Technical Field

[0001] This utility model relates to the field of track fasteners, and in particular to a novel track fastener with good positioning effect. Background Technology

[0002] Rail fasteners are key components in railway track structures that connect rails and sleepers. They are also known as "intermediate connecting parts" and prevent longitudinal crawling and lateral displacement of the rails.

[0003] Most track fasteners are one-piece units, and when they are damaged, the entire unit needs to be discarded, resulting in high maintenance costs later on.

[0004] Therefore, it is necessary to propose a new type of track fastener with good positioning effect to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a new type of track fastener with good positioning effect, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel track fastener with good positioning effect includes a track component, air pumps symmetrically installed on both sides of the track component, a mounting base installed at the bottom of the air pump, a base installed at the bottom of the mounting base, and a fastener body installed between the mounting base and the base.

[0007] Preferably, limiting claws are symmetrically installed at both ends of the two sides of the track component, and locking strips are symmetrically installed at the bottom of both sides of the track component. The limiting claws at both ends are attached to the two ends of the mounting base, and the locking strips are inserted between the mounting base and the base.

[0008] Preferably, the base has an insertion slot on the side near the track component, the top of the base is equipped with a first limiting seat and a second limiting seat, and the mounting seat has a through slot in the center.

[0009] Preferably, the fastener body has symmetrically installed insertion strips on both sides of its top, and a limiting strip is installed on the side of the fastener body away from the track component. The insertion strip is installed on the top of the mounting base through a through groove. The size of the limiting strip and the insertion groove are adapted to each other, and the limiting strip is inserted into the inner cavity of the insertion groove.

[0010] Preferably, the limiting strip is inserted into the inner cavity of the second limiting seat, and a reinforcing seat is installed on the top of the insertion strip, the reinforcing seat being fitted between the mounting seat and the base.

[0011] Preferably, the bottom of the two air pumps on opposite sides are symmetrically installed on both sides of the track component, and a filling tube is symmetrically installed on the opposite side of the two air pumps. A fixing seat is installed at the other end of the filling tube, and the fixing seat is installed on the top of the mounting seat. The filling tube is located at the top of the connector strip, and the filling tube and the mounting seat are located at the top and bottom of the connector strip, respectively. The air pump is used to inflate the filling tube, and the filling tube is used to position the connector strip.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This new type of track fastener with good positioning effect can assemble the track component, mounting base and base through the set mounting seat and base, and the limiting claws and locking strips on both sides of the track component. Based on this, it is convenient to disassemble and maintain it. After it is damaged, a single part can be directly replaced instead of replacing the whole part, which can effectively reduce maintenance costs.

[0013] 2. This new type of track fastener with good positioning effect can be fastened to the track through the fastener body. Based on this, it can fix the position of the rail, transfer the train load, provide elastic buffer and maintain the geometric stability of the track. The fastener body can be installed on the mounting base and base through the through groove and the plug groove through the set plug strip and limit strip. With the set second limit seat, the limit strip can be further limited. After installation, it can improve the overall tightness and make it more convenient to use.

[0014] 3. This new type of track fastener with good positioning effect can inflate the filling tube with air through the air pump. After the filling tube expands, it can reinforce the plug strip. This allows the filling tube and the mounting base to clamp the plug strip, so that the fastener body will not shake during use. Attached Figure Description

The plug strip 8 is installed on the top of the mounting base 5 through the through groove 13. The size of the limiting strip 17 and the plug groove 14 are matched. The limiting strip 17 is inserted into the inner cavity of the plug groove 14. The limiting strip 17 is inserted into the inner cavity of the second limiting seat 16. A reinforcing seat 9 is installed on the top of the plug strip 8. The reinforcing seat 9 fits between the mounting base 5 and the base 6. The bottom of the two air pumps 4 on opposite sides is symmetrically installed on both sides of the track component 1. The filling tube 10 is symmetrically installed on the opposite side of the two air pumps 4. A fixing seat 11 is installed at the other end of the filling tube 10. The fixing seat 11 is installed on the top of the mounting base 5. The filling tube 10 is located on the top of the plug strip 8. The filling tube 10 and the mounting base 5 are located at the top and bottom of the plug strip 8, respectively. The air pump 4 is used to inflate the filling tube 10. The filling tube 10 is used to position the plug strip 8. The mounting base 5 and base 6, along with the limiting claws 2 and locking strips 3 on both sides of the track component 1, allow for the assembly of the track component 1, mounting base 5, and base 6. This facilitates disassembly and maintenance, allowing for the direct replacement of individual parts instead of replacing the entire component, thus reducing maintenance costs. The fastener body 7 secures the component to the track, thereby fixing the rail position, transmitting train loads, providing elastic cushioning, and maintaining track geometric stability. The fastener body 7, through the insertion strip 8 and limiting... Strip 17 can be installed on mounting base 5 and base 6 through through slot 13 and plug slot 14.
