Technical Field
[0001] This utility model relates to the field of slide rail structure technology, and in particular to a durable new heavy-duty slide rail. Background Technology
[0002] In modern industry and machinery, heavy-duty slide rails, as key components supporting and guiding moving parts, are widely used in automation equipment, precision machinery, and large-scale equipment manufacturing. In traditional heavy-duty slide rail designs, to reduce frictional resistance and improve sliding efficiency, ball bearings are typically embedded between the guide rails. The rolling motion of these balls replaces traditional sliding friction, significantly improving the smoothness and load-bearing capacity of the slide rail. However, the guide rail portion of traditional heavy-duty slide rails is usually made of one-piece molded hard alloy or high-strength steel. While these materials ensure the structural strength and rigidity of the guide rail, their hardness often does not match that of the ball bearings (usually made of stainless steel, ceramic, or hard alloy). During long-term, high-frequency rolling contact, the relatively lower hardness of the guide rail surface gradually becomes subjected to continuous pressure from the higher hardness of the ball bearings, leading to wear and even minor deformation. This wear and deformation not only affect the accuracy and stability of the slide rail but can also cause vibration and noise, severely reducing the reliability of the heavy-duty slide rail and shortening its overall service life. Therefore, there is an urgent need for a new type of heavy-duty slide rail that can optimize the fit between the ball bearings and the guide rail, making the heavy-duty slide rail more durable. Utility Model Content

[0009] As described above, a durable new heavy-duty slide rail, wherein the mating mechanism further includes a plurality of limiting baffles respectively fixed on the first rail and the second rail, the limiting baffles being used to cover the openings at the ends of the first fitting groove and the second fitting groove respectively, so as to restrict the movement of the first guide bar along the extension direction of the first fitting groove and the movement of the second guide bar along the extension direction of the second fitting groove respectively.
[0010] As described above, a durable new heavy-duty slide rail has a guide rail groove on the first track along its length direction, and groove walls arranged opposite to each other on both sides of the guide rail groove along its length direction. The second track has guide rail edges arranged opposite to each other on both sides along its length direction. The first fitting groove is formed on the groove wall, and the second fitting groove is formed on the guide rail edge, so that the second track can be movably fitted into the guide rail groove along its length direction.
[0011] As described above, a durable new heavy-duty slide rail has guide rail grooves arranged oppositely on both sides along the length direction of the first rail, and the second rail consists of two sets of rails that are movably fitted into the opposite guide rail grooves.
[0012] As described above, a durable new heavy-duty slide rail has a mounting edge protruding on the side of the second rail away from the first rail, the mounting edge extending along the length direction of the second rail.
[0013] As described above, a durable new heavy-duty slide rail has a plurality of fixing holes arranged along its length on the second rail.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] This utility model discloses a heavy-duty slide rail with a mating mechanism between the first and second tracks. The mating mechanism consists of a first guide bar and a second guide bar clamped on opposite sides of multiple balls. This ensures that when the first and second tracks move relative to each other, the rolling of the balls occurs in direct contact with the first and second guide bars.

Based on this structure, the first and second guide bars can be made of steel, and the first and second tracks can be made of aerospace aluminum. This enhances the rigid contact between the guide bars and the balls during operation, greatly reducing the motion power required for the heavy-duty slide rail, increasing its load-bearing capacity, and extending its overall service life.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1: Please refer to the appendix Figure 1 To be continued Figure 2This embodiment provides a durable new heavy-duty slide rail, including a first track 1 and a second track 2 that are relatively movable along the length direction, and a cooperating mechanism 3 disposed between the first track 1 and the second track 2. The cooperating mechanism 3 includes a first guide bar 31, a second guide bar 32, and a plurality of arranged balls 33. The first guide bar 31 and the second guide bar 32 are relatively parallel. The plurality of balls 33 are rolled along the length direction of the first guide bar 31 between the first guide bar 31 and the second guide bar 32. The first guide bar 31 is spaced between the first track 1 and the balls 33, and the second guide bar 32 is spaced between the second track 2 and the balls 33. When the first track 1 and the second track 2 are relatively movable, the first guide bar 31 and the second guide bar 32 continuously press against the balls 33. In this embodiment of the heavy-duty slide rail, a mating mechanism 3 is provided between the first track 1 and the second track 2. The mating mechanism 3 uses a first guide bar 31 and a second guide bar 32 clamped on opposite sides of multiple balls 33. This ensures that when the first track 1 and the second track 2 move relative to each other, the rolling of the balls 33 occurs in direct contact with the first guide bar 31 and the second guide bar 32. The first track 1 and the second track 2 do not make mating contact with the balls 33 during this process. Based on this structure, the first guide bar 31 and the second guide bar 32 can be made of steel bars, and the balls 33 can be made of steel balls. Combined with the first track 1 and the second track 2, which can be made of aviation aluminum, the rigid contact between the guide bar and the balls 33 is enhanced during slide rail operation. This greatly reduces the motion power required by the heavy-duty slide rail, increases the load-bearing capacity of the heavy-duty slide rail, and extends the overall service life of the heavy-duty slide rail.
[0021] Preferably, the first guide bar 31, the second guide bar 32 and the ball 33 are all made of steel, and the first track 1 and the second track 2 are both made of aerospace aluminum.
[0022] Preferably, the cross-sections of the first guide bar 31 and the second guide bar 32 are fan-shaped.
[0023] Furthermore, the mating mechanism 3 also includes a first fitting groove 34 and a second fitting groove 35. The first fitting groove 34 is formed along the length direction of the first track 1 on the first track 1, and the second fitting groove 35 is formed along the length direction of the second track 2 on the second track 2. The first guide bar 31 is fitted into the first fitting groove 34, and the second guide bar 32 is fitted into the second fitting groove 35. Specifically, the fan-shaped convex surface of the first guide bar 31 is in contact with the bottom of the first fitting groove 34, and the fan-shaped concave surface of the first guide bar 31 abuts against the ball 33. The fan-shaped convex surface of the second guide bar 32 is in contact with the bottom of the second fitting groove 35, and the fan-shaped concave surface of the second guide bar 32 abuts against the ball 33. The first guide bar 31 is fixedly installed on the first track 1 by using the first fitting groove 34, and the second guide bar 32 is fixedly installed on the second track 2 by using the second fitting groove 35. The fan-shaped concave surfaces of the first guide bar 31 and the second guide bar 32 can play a certain role in surrounding the ball 33 and guide the rolling of the ball 33.
[0024] The mating mechanism 3 also includes multiple limiting baffles 36 respectively fixed on the first track 1 and the second track 2. The limiting baffles 36 are used to cover the openings at the ends of the first fitting groove 34 and the second fitting groove 35, respectively, to restrict the movement of the first guide strip 31 along the extension direction of the first fitting groove 34 and the movement of the second guide strip 32 along the extension direction of the second fitting groove 35. The limiting baffles 36 can effectively prevent the first guide strip 31 or the second guide strip 32 from dislodging from their corresponding fitting grooves.
[0025] The first track 1 has a guide rail groove 11 along its length direction, and the guide rail groove 11 has oppositely arranged groove walls 12 on both sides along its length direction. The second track 2 has oppositely arranged guide rail edges 21 on both sides along its length direction. The first fitting groove 34 is opened on the groove wall 12, and the second fitting groove 35 is opened on the guide rail edge 21, so that the second track 2 can be movably fitted into the guide rail groove 11 along its length direction.
[0026] Preferably, the first track 1 has guide rail grooves 11 arranged oppositely on both sides along the length direction, and the second track 2 is provided in two sets that are movably fitted into the opposite guide rail grooves 11, so that the relative movement of the first track 1 and the second track 2 is smoother and more stable.
[0027] Preferably, the second track 2 has a protruding mounting edge 22 on the side away from the first track 1, and the mounting edge 22 extends along the length of the second track 2 to facilitate the installation and connection of the corresponding external structure.
[0028] Preferably, the second track 2 has multiple fixing holes 23 arranged along its length to facilitate the installation and connection of corresponding external structures.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
