Detailed Implementation

[0013] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] like Figures 1 to 3 As shown, a one-way check mechanism for a product shelf push track, based on a rigid chain push-pull mechanism, includes a guide rail 2, a check block 3, a torsion spring 10, a push pin 14, a push linkage 12, and a one-way slide 20. The guide rail 2 is arranged along the push direction of the rigid chain. An installation groove 4 is formed on the upper surface of the guide rail 2. The check block 3 is arranged in the installation groove 4. The two sides of the check block 3 are respectively mounted on opposite side walls of the installation groove 4 through a rotating shaft 7. The check block 3 can rotate around the rotating shaft 7. The torsion spring 10 is mounted on the rotating shaft 7. The check block 3 is provided with a guide surface 8, an inclined surface 9, and a check part 11. The guide surface 8 is provided with an inclined surface 9 and a check part 11 at both ends. The ejector pin 14 is arranged vertically, and its upper end abuts against the inclined surface 9. The lower end of the ejector pin 14 is fitted into a one-way slide groove 20. The one-way slide groove 20 includes an inclined slide surface 21 and a horizontal slide surface 22 connected in sequence along the pushing direction. The bottom of the inclined slide surface 21 is connected to the horizontal slide surface 22. The one-way slide groove 20 is formed on the pushing linkage 12, and the pushing linkage 12 is connected to the chain pushing section 5 of the rigid chain push-pull mechanism.

[0016] like Figure 2 As shown, in the uncompressed state, the guide surface 8 of the torsion spring 10 is in the same plane as the upper surface of the guide rail 2. Torsion spring arms are respectively provided at both ends of the torsion spring 10, and the torsion spring arms are respectively fitted into the bottom of the mounting groove 4. The included angle between the guide surface 8 and the inclined surface 9 is 30°-60°.

[0017] like Figure 2 As shown, a mounting base 15 is provided at the lower part of the ejector pin 14, and the mounting base 15 is fixedly mounted below the guide rail 2 by screws 16.

[0018] like Figure 4 As shown, the rigid chain push-pull mechanism includes a chain, a sprocket 102, a chain storage box 1, and a motor 6; the motor 6 drives the sprocket 102 to rotate, and the chain meshes with the sprocket 102; the chain includes a chain pushing section 5 and a chain storage section 101, and the storage section 101 is disposed in the chain storage box 1.

[0019] like Figure 2 As shown, when the chain pusher segment 5 drives the goods along the push direction and along the guide rail to the check block 3, the upper end of the ejector pin 14 abuts against the inclined surface 9, and the lower end of the ejector pin 14 presses against the inclined sliding surface 21 of the one-way slide groove 20. In the uncompressed state, the torsion spring 10 has its guide surface 8 in the same plane as the upper surface of the guide rail 2, allowing the goods to pass smoothly along the push direction; Figure 3As shown, when the chain pushing section 5 drives the pushing linkage 12 to move in the opposite direction, the lower end of the ejector pin 14 slides down along the inclined sliding surface 21 of the one-way slide groove 20 to the horizontal sliding surface 22. The ejector pin 14 descends, the torsion spring deforms under torsion, and the check block 3 flips over, causing the check part 11 to protrude from the guide rail to block the goods. The check mechanism is in the check state. When the chain pushing section 5 drives the pushing linkage 12 to move along the pushing direction again, the lower end of the ejector pin 14 slides up along the horizontal sliding surface 22 of the one-way slide groove 20 to the inclined sliding surface 21. The ejector pin 14 descends, and at the same time, the deformation force of the torsion spring drives the rotating shaft to reset, so that the guide surface 8 and the upper surface of the guide rail 2 are in the same plane, and the goods can pass smoothly along the pushing direction.

[0020] In addition, during cargo transfer, when the cargo is stored on the guide rail, the chain push section 5 is controlled to drive the push linkage 12 to move in the opposite direction, so that the anti-return mechanism is in the anti-return state to block the cargo, making the transfer of cargo safer.

[0021] This utility model discloses a one-way check mechanism for a product shelf push track, suitable for use in rigid chain push-pull mechanisms. When the chain push segment 5 drives the goods to pass through the check block 3 in the push direction, the goods can pass smoothly. When the chain push segment 5 drives the push linkage 12 to move in the opposite direction, the check block 3 flips, and the check part 11 protrudes from the guide rail to block the goods. This prevents the goods from falling due to misoperation or accidental shaking that causes the chain push segment 5 to move in the opposite direction. The one-way check mechanism also has the advantages of compact structure and low manufacturing cost.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
