[0032] The positioning plate 30 is detachably mounted on the U-shaped plate 31 through the cylindrical pin 33, so that different sizes of the positioning plate 30 can be selected according to different sizes of the rack 2, so as to ensure that the rack 2, in particular the hollow groove 22, is matched with the positioning plate 30, thereby ensuring the stability of the device.

[0033] After locking the rack 2, one side of the limiting block 35 should be in abutment with the positioning plate 30, so as to position the two ends of the rack 2 and avoid the shaking of the positioning plate 30 from moving the rack 2.

[0034] As shown in Figure 3 and Figure 4 Further, the top of the locking pin 34 is further connected with the sliding mechanism 4, and the sliding mechanism 4 comprises a sliding groove 41 fixed on the end face of the guide rail 1, the bottom of the sliding groove 41 is provided with a baffle 42, and the sliding block 43 is slidably mounted in the sliding groove 41, and the tail end of the sliding block 43 is fixedly connected with the locking pin 34.

[0035] The locking pin 34 is movably mounted on the end face of the guide rail 1 through the sliding mechanism 4, and when it is necessary to lock the rack 2, the locking pin 34 can be inserted into the pin hole 32 by sliding the sliding block 43 downward. When it is necessary to replace the rack 2, the locking pin 34 can be driven out of the pin hole 32 by sliding the sliding block 43 upward, so as to complete the unlocking, thereby improving the convenience of use of the device.

[0036] As shown in Figure 1 Further, the surface of the guide rail 1 provided with the U-shaped groove 10 is further provided with an arc-shaped V-shaped groove track 11, the arc-shaped V-shaped groove track 11 is arranged along the length direction of the guide rail 1, and the U-shaped groove 10 is located at the bottom of the arc-shaped V-shaped groove track 11. Further, the tooth 21 is a cylindrical tooth shape.

[0037] The arc-shaped V-shaped groove track 11 is used for keeping the rolling of the rolling body on the frame.

[0038] As shown in Figure 1 Further, a plurality of mounting holes 12 are arranged on any side surface of the guide rail 1 except the two end surfaces and the arc-shaped V-shaped groove track 11.

[0039] The mounting hole 12 is used for connecting the guide rail 1 with different equipment, and the mounting hole 12 is arranged on multiple surfaces, so as to improve the mounting flexibility of the guide rail 1.

[0040] Further, the material of the guide rail 1 and the rack 2 is stainless steel.

[0041] The utility model will be further described in detail in combination with specific embodiments.

[0042] Embodiment 1

[0043] As shown in Figure 1 and Figure 2As shown, the positioning plate 30 is fixed on the U-shaped plate 31 by the cylindrical pin 33, which is inserted into the pin hole 32 on one side of the positioning plate 30 through the horizontal plate 311 to fix the positioning plate 30 and the U-shaped plate 31. When locking the rack 2, the rack 2 is placed at the bottom of the U-shaped groove 10 so that the rack 2 is tightly fitted with the U-shaped groove 10. When placing, attention should be paid to the opening of the tooth 21 and the hollow groove 22 facing the outside of the U-shaped groove 10. At the same time, the positioning plate 30 on both sides is respectively passed out of the hollow groove 22 at both ends of the rack 2, and then the rack 2 is locked with the positioning plate 30 by the locking pin 34. After the locking pin 34 locks the rack 2, it needs to ensure that one side is tightly fitted with the rack 2.

[0044] The positioning plate 30 fixes both ends of the rack 2 to avoid the rack 2 moving along the length direction of the guide rail 1 during use. After the locking pin 34 locks the rack 2, it needs to ensure that one side is tightly fitted with the rack 2. On the one hand, it tightens the rack 2 and the positioning plate 30 to avoid their separation, and on the other hand, it also avoids the rack 2 shaking along its installation direction (i.e. the depth direction of the U-shaped groove), ensuring the stability of the device during use and the convenience and speed of the installation process.

[0045] The surface of the guide rail 1 provided with the U-shaped groove 10 is also provided with an arc-shaped V-groove track 11, which is arranged along the length direction of the guide rail 1, and the U-shaped groove 10 is located at the bottom of the arc-shaped V-groove track 11. The arc-shaped V-groove track 11 is used to keep the rolling of the rolling body on the holder, so as to make the guide rail 1 slide normally. The guide rail 1 is provided with a plurality of mounting holes 12 on any side surface except the two end surfaces and the arc-shaped V-groove track 11, which is used to connect the guide rail 1 with different equipment. The mounting holes 12 are provided on multiple surfaces to improve the installation flexibility of the guide rail 1.

[0046] When the rack 2 needs to be taken out, the locking pin 34 is pulled out to take down the rack 2.

[0047] Example 2

[0048] As shown in Figures 3-5 Based on example 1, example 2 further provides a device structure and working principle to further improve the convenience of the device:

[0049] The sliding mechanism 4 is also connected to the top of the locking pin 34, and the sliding mechanism 4 comprises a sliding groove 41 fixed on the end face of the guide rail 1, the bottom of the sliding groove 41 is provided with a baffle 42, and the sliding block 43 is slidably installed in the sliding groove 41, and the tail end of the sliding block 43 is fixedly connected with the locking pin 34. The locking pin 34 is movably installed on the end face of the guide rail 1 through the sliding mechanism 4, and when it is necessary to lock the rack 2, the sliding block 43 only needs to be slid downward to insert the locking pin 34 into the pin hole 32. When it is necessary to replace the rack 2, the sliding block 43 only needs to be slid upward to drive the locking pin 34 to be separated from the pin hole 32, so that the unlocking is completed, and the convenience of use of the device is improved.

[0050] The positioning plate 30 is detachably installed on the U-shaped plate 31 through the cylindrical pin 33, so that different sizes of the positioning plate 30 can be selected according to different sizes of the rack 2, so as to ensure that the rack 2, in particular the hollow groove 22, is matched with the positioning plate 30, so as to ensure the stability of the device. After the rack 2 is locked, one side of the limiting block 35 should abut against the positioning plate 30, so as to position the two end portions of the rack 2, and avoid that the rack 2 is moved by the shaking of the positioning plate 30.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
