[0002] As the name suggests, shelves are racks used to place goods. They are widely used in the express delivery industry and are mainly used to hold goods. The size of the shelves is usually selected according to the quantity of goods, so their size and materials are quite diverse.

[0003] In order to improve the efficiency of transferring goods in and out of shelves, slide rails and shuttles are generally installed between shelves. With the help of remote control, the shuttle slides back and forth on the slide rails between shelves to store and transfer goods. Therefore, it is also called shuttle-type shelf. However, in a relatively dark and humid environment, when the shuttle stores and transfers goods back and forth, the inside of the slide rails of the shelf is prone to rust, which makes the friction between the shuttle and the slide rails greater, thereby affecting the shuttle's movement efficiency and causing the need for regular maintenance and upkeep of the slide rails.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are:

[0026] 1. In the present invention, by setting a lubrication structure, first open the pipe plug, then fill the lubricating oil into the material pipe, then reinsert the pipe plug into the material pipe, and then start the connecting piece. When the vehicle body moves with the help of the pulley to transfer the goods, the connecting piece drives the dropper to move. When the dropper moves to contact the node protrusion, the node protrusion will push the card ball to move the card ball upward. When the card ball moves upward, the spring A begins to contract, and a gap will appear between the card ball and the dropper. At this time, the lubricating oil in the dropper will flow out from the gap between the card ball and the dropper, and the lubricating oil will slide along the guide groove of the card ball, slide to the bottom of the card ball and finally drip onto the slide rail. When the vehicle body moves, every time the dropper passes a protruding node, the card ball will move upward, and the lubricating oil will also Then it flows out, and after passing the node protrusion, the spring A will give the card ball an elastic force again, so that the card ball is stuck at the lower end port of the dropper, and the card ball will block the lubricating oil again, thereby achieving the effect of quantitatively dripping the lubricating oil every time it passes the node protrusion. When the lubricating oil is not needed for a long time, the electric push rod is directly started, and the electric push rod will drive the magnet to move downward, and the magnet will use the magnetic force to drive the magnetic block to move downward, and the magnetic block drives the plug plate and the rubber plug to move downward and block the retaining ring, thereby achieving the effect of blocking the lubricating oil. By setting the lubrication structure, the lubricating oil can be easily and quickly dripped into the inside of the slide rail, thereby reducing the friction between the pulley and the inside of the slide rail, and to a certain extent improving the service life of the slide rail.

[0027] 2. In the present invention, by setting a guide groove, the guide groove is opened at the lower third of the card ball, so that when the card ball hits the node protrusion, the lubricating oil can quickly slide down along the guide groove on the arc surface of the card ball. The connecting position of the guide groove is polished and ground, which can make it easier for the lubricating oil in the guide groove to quickly gather together and drip onto the slide rail.

[0028] 3. In the present invention, by providing an assembly structure, after the lubricating oil is loaded into the material pipe, the two clamping plates are pulled to move the two clamping plates in a direction approaching each other. At this time, the spring B is in a compressed state. The baffle is then placed between the two fixing rings. The two clamping plates are then released. At this time, the spring B will give the clamping plate an elastic force to move the two clamping plates in a direction away from each other. The telescopic rod will accordingly extend and retract. The telescopic rod has the effect of limiting the direction of the elastic force of the spring B. At this time, the clamping plate will be stuck in the fixing ring, achieving the effect of quickly fixing the baffle pipe on the connecting piece. Then, the two clamping plates are pulled to move the two clamping plates in a direction away from each other. The material pipe is then placed between the two clamping plates. The two clamping plates are then released. At this time, the spring C will give the clamping plate an elastic force to move the two clamping plates in a direction approaching each other. At this time, the two clamping plates will clamp the material pipe, and the anti-slip pad has the effect of improving the fixing strength of the clamping plate to the material pipe. By providing an assembly structure, the material pipe can be quickly fixed to the connecting piece. At the same time, it is more convenient to assemble the material pipe when repeatedly filling the lubricating oil.

[0029] 4. In the present invention, by setting a smearing structure, when it is necessary to smear the lubricating oil dripping on the slide rail, the cylinder is directly started, and the cylinder drives the adjusting plate to move downward, and the downward movement of the adjusting plate drives the mounting plate to move downward, and the mounting plate drives the smearing brush to move downward and contact the surface of the slide rail. When the vehicle body moves to transfer the goods, the smearing brush will evenly smear the lubricating oil dripping on the slide rail. When the adjusting plate moves up and down, the limit rod will slide along the surface of the spacer block, thereby achieving the effect of limiting the moving position of the mounting plate and the smearing brush. By setting the smearing structure, the effect of quickly and evenly smearing the lubricating oil on the slide rail is achieved.

[0030] 5. In the present invention, by setting a smear brush, the bristles of the smear brush are concave from the outside to the inside, which can prevent the bristles of the smear brush from directly contacting the node protrusions, thereby preventing the bristles of the smear brush from colliding with the node protrusions, causing splashing of lubricating oil, and at the same time facilitate the diffusion of lubricating oil to both sides along the bristles of the smear brush, thereby achieving the effect of better and more evenly applying the lubricating oil.

[0041] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Example 1, as Figure 1-9As shown, the present invention provides a shuttle-type rack, including a rack 1, with slide rails 2 welded on both sides of the interior of the rack 1, two pulleys 3 being slidably connected to the inner wall of the slide rail 2, and connectors 4 being installed on the surfaces of the two pulleys 3, and the ends of the two connectors 4 close to each other are fixedly connected to a vehicle body 5, a cargo tray 6 is provided above the vehicle body 5, and a lubrication structure 7 for lubricating the slide rail 2 is provided on the side of the two connectors 4 away from each other, and an assembly structure 8 is provided on one side of the connector 4.

[0044] The specific settings and functions of the lubrication structure 7, the assembly structure 8 and the smearing structure 9 are described in detail below.

[0045] like Figure 5 and Figure 6As shown, the lubrication structure 7 includes a material pipe 701 for containing lubricating oil, a pipe plug 702, a dropper 703 for titrating the lubricating oil, a retaining ball 707 for applying the lubricating oil, and a node protrusion 719 for titrating the lubricating oil at a fixed distance. When the vehicle body 5 slides along the inner wall of the slide rail 2 with the help of the pulley 3, the retaining ball 707 can drop the lubricating oil on the slide rail 2 each time it passes through a node protrusion 719, thereby lubricating the surface of the slide rail 2, thereby improving the efficiency of the vehicle body 5 in transporting goods. The arc surface of the material pipe 701 is connected with a pipe plug 702 through interference fit. The arc surface of the lower end of the material pipe 701 is connected with a dropper 703. The lower end of the dropper 703 is conical. The inner wall of the dropper 703 is fixedly connected with a circular plate 704. The surface of the circular plate 704 is evenly provided with a number of leakage holes 705 for the flow of lubricating oil. The lower surface of the circular plate 704 is fixedly connected with a spring A706. The lower end of the spring A706 is fixedly connected with a card ball 707. The card ball 707 is connected to the lower end of the dropper 703. The slide rail 2 is abutted against the position of the ball 707, and several node protrusions 719 are evenly fixedly connected. Several node protrusions 719 are offset from the pulley 3. When the vehicle body 5 moves, the ball 707 passes through the node protrusions 719, and the node protrusions 719 push the ball 707, causing the ball 707 to move upward. At this time, the lubricating oil in the dropper 703 flows out from the gap between the ball 707 and the dropper 703, and then flows onto the slide rail 2, lubricating the slide rail 2. The lower arc surface of the ball 707 is evenly provided with several guide grooves 716. Several guide grooves 716 are located at the lower third of the ball 707. The connecting positions of the guide grooves 716 are polished and ground. When the lubricating oil flows out from the gap between the ball 707 and the dropper 703, it can drip along the guide grooves 716 of the ball 707, further facilitating the lubricating oil to drip onto the slide rail 2. The inner wall of the dropper 703 is fixedly connected with a retaining ring 708, and the inner wall of the dropper 703 is slidably connected to a plug plate 709 for blocking the retaining ring 708. A number of adjustment holes 710 are evenly provided on the surface of the plug plate 709, and two magnetic blocks 711 are fixedly connected to the upper surface of the plug plate 709. The arc surface of the dropper 703 is fixedly connected with two electric push rods 712, and the output end of the electric push rod 712 is fixedly connected with a magnet 713. The arc surface of the plug plate 709 is fixedly connected with two limit blocks 714. The inner wall of the dropper 703 is provided with two limit grooves 715. The limit block 714 is slidably connected to the dropper 703 with the help of the limit grooves 715, so that the magnetic force of the magnet 713 on the magnetic block 711 can drive the plug plate 709 inside the dropper 703 to block the retaining ring 708, and then the dropper 703 is blocked when the slide rail 2 does not need to be lubricated for a long time. A rubber plug 717 for sealing the lubricating oil is fixedly connected to the lower surface of the plug plate 709 . The size of the rubber plug 717 matches the size of the interior of the retaining ring 708 , thereby achieving a better sealing effect on the retaining ring 708 .A slide rod 718 is fixedly connected to the lower surface of the circular plate 704, and the lower end of the slide rod 718 is slidably connected to the inside of the sliding ball, thereby achieving the effect of limiting the moving position of the card ball 707 while limiting the direction of the elastic force of the spring A706.

[0046] The effect achieved by the entire lubricating structure 7 is as follows: by setting the lubricating structure 7, first open the pipe plug 702, then load the lubricating oil into the material pipe 701, then reinsert the pipe plug 702 onto the material pipe 701, and then start the connecting piece 4. When the vehicle body 5 moves with the help of the pulley 3 to transfer the goods, the connecting piece 4 drives the dropper 703 to move. When the dropper 703 moves to contact the node protrusion 719, the node protrusion 719 will push the card ball 707 to move the card ball 707 upward. When the card ball 707 moves upward, the spring A706 begins to contract, and a gap will appear between the card ball 707 and the dropper 703. At this time, the lubricating oil in the dropper 703 will flow out from the gap between the card ball 707 and the dropper 703, and the lubricating oil will slide along the guide groove 716 of the card ball 707, and slide to the bottom of the card ball 707 and finally drip onto the slide rail 2. When the vehicle body 5 moves, each time the dropper 703 passes a protruding node, the card ball When the lubricating oil is applied to the cylinder 714, the spring 706 will re-apply the force to the cylinder 707, so that the cylinder 714 can be retracted to prevent the cylinder 714 from sliding out of the cylinder 714. By setting the guide groove 716, the guide groove 716 is opened at the lower third of the position of the locking ball 707, so that when the locking ball 707 hits the node protrusion 719, the lubricating oil can quickly slide down along the guide groove 716 on the arc surface of the locking ball 707. The connecting position of the guide groove 716 is polished and ground, which can make it easier for the lubricating oil in the guide groove 716 to quickly gather together and drip onto the slide rail 2.

[0047] like Figure 4 and Figure 8As shown, the assembly structure 8 includes two fixing rings 801, and the two fixing rings 801 are fixedly connected to the surface of the connecting member 4. The interior of the fixing ring 801 is slidably connected to a card plate 802, and the cross section of the card plate 802 is "L" shaped. The two card plates 802 are fixedly connected to the side close to each other with a spring B803, and the two springs B803 are fixedly connected to the side close to each other with a spacer 804. Both sides of the spacer 804 are fixedly connected to a telescopic rod 809, and the output end of the telescopic rod 809 is fixed to the card plate 802. The spacer 804 is fixedly connected to the side of the connector 4 with a baffle 810, and the baffle 810 is fixedly connected to the side of the material pipe 701 with two connecting plates 805. The two connecting plates 805 are fixedly connected to the side close to each other with a spring C806. The two springs C806 are fixedly connected to the end close to each other with a clamping plate 807. The two clamping plates 807 are located on both sides of the material pipe 701, which can quickly fix the material pipe 701 and facilitate the stable dripping of lubricating oil from the material pipe 701. The two clamping plates 807 are fixedly connected to the side close to each other with anti-skid pads 808. The side of the anti-skid pads 808 away from the clamping plates 807 is uniformly provided with anti-skid protrusions. The anti-skid pads 808 are rubber pads. The side of the anti-skid pads 808 away from the clamping plates 807 abuts against the material pipe 701, achieving the effect of increasing the friction between the clamping plates 807 and the material pipe 701, thereby improving the fixing strength of the material pipe 701.

[0048] The effect achieved by the entire assembly structure 8 is that, by setting the assembly structure 8, after the lubricating oil is loaded into the material tube 701, the two card plates 802 are pulled to move the two card plates 802 in the direction of approaching each other. At this time, the spring B803 is in a compressed state, and then the baffle 810 is placed between the two fixing rings 801. Then, the two card plates 802 are released. At this time, the spring B803 will give the card plates 802 an elastic force to move the two card plates 802 in the direction of moving away from each other, and the telescopic rod 809 will be extended and retracted accordingly. The telescopic rod 809 has the effect of limiting the direction of the elastic force of the spring B803. At this time, the card plate 802 will be stuck in the fixing ring 801, achieving the effect of quickly moving the baffle 810. 0 fixes the pipe on the connector 4, then pulls the two clamps 807 to move the two clamps 807 away from each other, then places the material pipe 701 between the two clamps 807, and then releases the two clamps 807. At this time, the spring C806 gives the clamps 807 elastic force to move the two clamps 807 towards each other. At this time, the two clamps 807 clamp the material pipe 701, and the anti-slip pads 808 have the effect of improving the fixing strength of the clamps 807 on the material pipe 701. By providing the assembly structure 8, the material pipe 701 can be quickly fixed on the connector 4. At the same time, it is more convenient to assemble the material pipe 701 when repeatedly filling with lubricating oil.

[0049] Example 2, based on Example 1, Figure 8 and Figure 9 As shown, a smearing structure 9 is provided on the side of the spacer 804 away from the baffle 810, and the smearing structure 9 includes a cylinder 91, which is fixedly connected to the surface of the spacer 804, and the output end of the cylinder 91 is fixedly connected to an adjusting plate 92, and the cross-section of the adjusting plate 92 is "L"-shaped, and the long arm end of the adjusting plate 92 is fixedly connected to a mounting plate 93 by means of bolts, and two smearing brushes 94 are fixedly connected to the lower surface of the mounting plate 93, and the upper end of the mounting plate 93 is fixedly connected to a limiting rod 95, and the upper end of the limiting rod 95 slides through the spacer 804, so that the lubricating oil can be evenly applied to the inner wall of the slide rail 2 with the help of the lubrication structure 7. The bristles of the smear brush 94 are concave from the outside to the inside, and the concave size of the bristles of the smear brush 94 is adapted to the size of the node protrusion 719, so that the concave position of the smear brush 94 can provide space for the node protrusion 719, thereby preventing the node protrusion 719 from moving the smear brush 94 and preventing the lubricating oil from splashing. At the same time, after the smear brush 94 contacts the lubricating oil, the lubricating oil can be assisted to penetrate to both sides, thereby making the lubricating oil more evenly spread on the slide rail 2 to a certain extent.

[0050] The effect achieved by the entire smearing structure 9 is that, by setting the smearing structure 9, when it is necessary to smear the lubricating oil dripping on the slide rail 2, the cylinder 91 is directly started, and at this time, the cylinder 91 drives the adjusting plate 92 to move downward, and the adjusting plate 92 moves downward to drive the mounting plate 93 to move downward, and the mounting plate 93 drives the smearing brush 94 to move downward and contact the surface of the slide rail 2. When the vehicle body 5 moves to transfer the goods, the smearing brush 94 will evenly smear the lubricating oil dripping on the slide rail 2. When the adjusting plate 92 moves up and down, the limit rod 95 will slide along the surface of the spacer 804, thereby achieving the effect of limiting the moving position of the mounting plate 93 and the smearing brush 94. By setting the smearing structure 9, the effect of quickly and evenly smearing the lubricating oil on the slide rail 2 is achieved. By setting up the smear brush 94, the bristles of the smear brush 94 are concave from the outside to the inside, which can prevent the bristles of the smear brush 94 from directly contacting the node protrusion 719, thereby preventing the bristles of the smear brush 94 from colliding with the node protrusion 719, causing the lubricating oil to splash, and at the same time, it makes it easier for the lubricating oil to spread to both sides along the bristles of the smear brush 94, thereby achieving the effect of better and more evenly applying the lubricating oil.

Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
