Description

Technical Field

[0001] This utility model relates to the field of track technology, and in particular to multi-dimensional fixed track fasteners. Background Technology

[0002] In modern transportation systems, tracks are crucial components that carry and guide the movement of transport vehicles, and their importance is self-evident. Whether it's railways, urban rail transit, or various industrial transport tracks, the stability and reliability of the tracks directly affect the safe and efficient operation of the entire transportation system. Effective track fixing is a fundamental condition for ensuring the safe and efficient operation of the transportation system. Most existing track fixing methods use nut-adjusting springs. While this method can achieve track fixing to a certain extent, its fixing effect is limited when dealing with complex operating environments and forces acting in different directions, making it difficult to meet multi-dimensional fixing requirements. Therefore, this utility model proposes a multi-dimensional fixing track fastener. Utility Model Content

[0003] The purpose of this invention is to address the problem that most track fixing methods in the background technology use nut-adjusting springs. While this method can fix the track to a certain extent, its fixing effect is limited when dealing with complex operating environments and forces from different directions, making it difficult to meet multi-dimensional fixing needs. Therefore, this invention proposes a multi-dimensional fixing track fastener.

[0004] The technical solution of this utility model is a multi-dimensional fixed track fastener, including a track, an embedded base plate set on the bottom surface of the track, two limiting screws fixedly set on the upper surface of the embedded base plate, and a set of limiting nuts threaded onto each limiting screw; a support plate movably sleeved on the limiting screws, and a fastening component for fixing the track fixedly set on the upper surface of the support plate.

[0005] Optionally, the fastening assembly includes a guide seat fixedly disposed on the upper surface of the support plate, a fixing nut fixedly disposed at one end of the guide seat, a fixing block slidably disposed inside the guide seat, two limiting blocks fixedly disposed at one end of the fixing block, and an adjusting bolt rotatably disposed at the other end of the fixing block, the adjusting bolt being threadedly engaged with the fixing nut.

[0006] Optionally, the fastening assembly further includes a limiting rod that is movably sleeved on the limiting nut, the outer wall of the limiting nut being fitted with a spring, one end of the spring being connected to the support plate, and the other end of the spring being connected to the limiting rod.

[0007] Optionally, a shock-absorbing buffer pad is provided between the track and the embedded base plate.

[0008] Optionally, multiple limiting holes and slots are provided on both sides of the track.

[0009] Optionally, one end of the limiting block is inclined.

[0010] Optionally, the limiting rod is configured with an "L" shaped structure.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This utility model utilizes a pre-embedded base plate, a limiting screw, a limiting nut, and a unique fastening assembly to work together. Rotating the adjusting bolt moves the fixing block, which in turn moves the limiting block to press the two sides of the track tightly. Then, rotating the limiting nut moves the limiting rod downward, allowing one end of the limiting rod to be inserted into the limiting hole groove. This enables multi-dimensional and stable fixation of the track, effectively responding to forces from different directions and greatly improving the stability and reliability of track fixation, thus meeting the multi-dimensional fixation requirements under complex operating environments.

[0013] Furthermore, by setting a buffer pad between the track and the embedded base plate, this utility model can effectively absorb the vibration and impact generated during track operation, reduce the damage to the track and fixed structure caused by vibration, and extend the service life of the track and fixed device. At the same time, the limiting rod is movably sleeved on the limiting nut and connected to the support plate through a spring. This structure allows the spring to play a buffering and adaptive adjustment role when the track is subjected to vibration or a certain degree of displacement, further enhancing the adaptability of the track fixing structure to complex operating environments and ensuring that the track can maintain stable operation under various working conditions.

[0027] Example

[0028] like Figure 1 and Figure 2As shown, the multi-dimensional fixed track fastener proposed in this utility model includes a track 1, an embedded base plate 2 set on the bottom surface of the track 1, which can stably install the track 1 and prevent shaking. Two limiting screws 3 are fixedly set on the upper surface of the embedded base plate 2, and the embedded base plate 2 and the limiting screws 3 are integrally formed to increase their strength and improve the stability of the support. A set of limiting nuts 4 are threaded onto the limiting screws 3 respectively. A support plate 5 is movably sleeved on the limiting screws 3, and the support plate is located between the limiting nuts 4 to facilitate the adjustment of the height of the support plate 5. A fastening component 6 for fixing the track 1 is fixedly set on the upper surface of the support plate 5, which can fasten the track 1 in multiple dimensions.

[0029] like Figure 3 and Figure 4 As shown, the fastening assembly 6 includes a guide seat 61 fixedly mounted on the upper surface of the support plate 5. The guide seat 61 is hollow inside. A fixing nut 62 is fixedly mounted on one end of the guide seat 61. A fixing block 63 is slidably mounted inside the guide seat 61 to limit the fixing block 63 and make it move stably. Two limiting blocks 64 are fixedly mounted on one end of the fixing block 63 to facilitate the limiting block 64 to limit the track 1. An adjusting bolt 65 is rotatably mounted on the other end of the fixing block 63. The adjusting bolt 65 is threadedly connected to the fixing nut 62 to facilitate the adjustment of the limiting block 64 to limit the track 1.

[0030] Furthermore, the fastening assembly 6 also includes a limiting rod 66 that is movably sleeved on the limiting nut 4. A spring 67 is sleeved on the outer wall of the limiting nut 4. One end of the spring 67 is connected to the support plate 5, and the other end of the spring 67 is connected to the limiting rod 66, so as to adjust the height of the limiting rod 66, thereby fastening the track 1 from different directions and improving stability.

[0031] like Figure 1 and Figure 2 As shown, a shock-absorbing buffer pad 7 is provided between the track 1 and the embedded base plate 2 to dampen the track 1 and ensure stability.

[0032] Secondly, multiple limiting holes and slots 8 are provided on both sides of the track 1 to facilitate the insertion of the limiting rod 66 to limit the track 1.

[0033] Furthermore, one end of the limiting block 64 is inclined to facilitate stable contact with both sides of the track 1 and improve the stability of the limiting.

[0034] In addition, the limiting rod 66 is designed with an "L" shape, which makes it easy for one end of the limiting rod 66 to be inserted into the limiting hole groove 8.

[0035] The working principle of this embodiment is as follows: First, the pre-embedded base plate 2 is set on the bottom surface of the track 1. The two limiting screws 3 on the pre-embedded base plate 2 pass through the support plate 5. By rotating the limiting nut 4, the height position of the support plate 5 can be adjusted, thereby realizing the initial positioning and fine adjustment of the track 1 in the vertical direction.

[0036] Regarding the fastening assembly 6, the guide seat 61 is fixed to the support plate 5, and the fixing nut 62 is located at one end of the guide seat 61. When the adjusting bolt 65 is rotated, since the adjusting bolt 65 is threadedly engaged with the fixing nut 62, the rotation of the adjusting bolt 65 is converted into axial movement, which in turn drives the fixing block 63 to slide inside the guide seat 61. As the fixing block 63 moves, the limiting block 64 at one end of the fixing block 63 presses against both sides of the track 1, thereby achieving horizontal fastening of the track and resisting horizontal forces.

[0037] Meanwhile, the limiting rod 66 is movably sleeved on the limiting nut 4 and connected to the support plate 5 via the spring 67. When the limiting nut 4 is rotated, it moves downward, causing the limiting rod 66 to move downward. Since the limiting rod 66 has an "L"-shaped structure, one end of it can be inserted into the limiting slots 8 opened on both sides of the track 1, further limiting and fixing the track in the horizontal and vertical directions, thus enhancing the stability of the fixation.

[0038] In addition, the buffer pad 7 set between the track 1 and the embedded base plate 2 can play a role in shock absorption and buffering when the track is subjected to various forces, protecting the track and other components, extending their service life, and further improving the stability and reliability of the entire track fixing system in complex operating environments, meeting multi-dimensional fixing requirements.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
