[0019] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. shall be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0020] Referring to Figures 1 to 5 , the present invention discloses a thruster, which includes a bracket 100, a cargo rail 200, a pushing seat 300 and an elastic member 400. A stop block 110 is provided at the front end of the bracket 100; the cargo rail 200 is slidably arranged on the bracket 100 in the front-rear direction, the cargo rail 200 is used for carrying goods, and a baffle 210 is provided at the front end of the cargo rail 200; the pushing seat 300 is slidably arranged on the cargo rail 200, and an abutting portion 310 is provided on the pushing seat 300. When the cargo rail 200 drives the pushing seat 300 to move forward, the abutting portion 310 abuts against the stop block 110 and stops the pushing seat 300 from moving forward, so as to open the limiting space formed between the pushing seat 300 and the baffle 210, and the limiting space is used for limiting goods; the elastic member 400 is used to drive the pushing seat 300 to move towards the front end of the cargo rail 200, so that the pushing seat 300 can press the goods on the cargo rail 200 against the baffle 210.

[0021] The bracket 100 is used to connect with a shelf or other external equipment, and the bracket 100 serves to support the cargo rail 200 and the goods on the cargo rail 200. The cargo rail 200 is arranged on the bracket 100, and the cargo rail 200 is limited on the bracket 100 to prevent the cargo rail 200 from accidentally falling off the bracket 100. The length directions of the bracket 100 and the cargo rail 200 are both in the front-rear direction. Initially, the cargo rail 200 is in the working position, and the bracket 100 and the cargo rail 200 coincide in the front-rear position. At this time, the space occupied by the thruster is the smallest, and the elastic member 400 is in a non-energized or less-energized state. The elastic member 400 drives the pushing seat 300 to move forward, so that the distance between the pushing seat 300 and the baffle 210 is the smallest.

[0022] Referring to Figure 4 and Figure 5, when it is necessary to store goods, pull the cargo rail 200 forward. The cargo rail 200 carries the baffle 210 and the pushing seat 300 to move forward. The abutting portion 310 will abut against the stop block 110. The stop block 110 prevents the pushing seat 300 from moving forward continuously. The elastic member 400 stores energy, and the cargo rail 200 can continue to move forward. Most of the area of the cargo rail 200 moves in front of the bracket 100, so that the distance between the pushing seat 300 and the baffle 210 becomes larger, so that the limiting space formed between the pushing seat 300 and the baffle 210 is opened. At this time, goods can be conveniently and quickly placed on the cargo rail 200. The limiting space is used to limit the goods. Finally, push the cargo rail 200 backward. The cargo rail 200 carries the pushing seat 300, the goods and the baffle 210 to move backward. The abutting portion 310 disengages from the stop block 110. The elastic member 400 releases energy. The elastic member 400 drives the pushing seat 300 to move toward the front end of the cargo rail 200, so that the pushing seat 300 presses the goods against the baffle 210. The operation method of the pusher is simple, the operation steps are simple and convenient, which is convenient for replenishment and has high replenishment efficiency.

[0023] The cargo rail 200 and the pushing seat 300 are connected by a sliding mechanism. The sliding mechanism confines the pushing seat 300 to move back and forth along the cargo rail 200.

[0024] Refer to Figure 1 and Figure 6 , in some of the embodiments, a guiding hole 240 is provided in the middle of the cargo rail 200. The guiding hole 240 penetrates the upper and lower surfaces of the cargo rail 200. The length direction of the guiding hole 240 is the front-back direction, so that the whole of the cargo rail 200 is in a frame shape. Refer to Figure 7 , the bracket 100 is also in a frame shape. When the cargo rail 200 is directly above the bracket 100, the cargo rail 200 covers the bracket 100. The cargo rail 200 can be an integrally formed structure or a split structure.

[0025] A guiding block 320 is connected to the pushing seat 300. The guiding block 320 is inserted into the guiding hole 240. A part of the area of the guiding block 320 abuts against the lower surface of the side wall of the guiding hole 240. The cooperation between the guiding block 320 and the guiding hole 240 enables the pushing seat 300 to move back and forth along the cargo rail 200, preventing the pushing seat 300 from moving upward to disengage from the cargo rail 200.

[0026] Refer to Figure 3 and Figure 5 , in some of the embodiments, the abutting portion 310 is provided on the guiding block 320, and the stop block 110 extends into the guiding hole 240. The side wall of the guiding hole 240 serves to enclose the guiding block 320 and the stop block 110. The guiding block 320 moves in the guiding hole 240, and the stop block 110 can block the abutting portion 310, preventing the guiding block 320 and the stop block 110 from being exposed, thereby preventing the guiding block 320 and the stop block 110 from interfering with the goods or other components.

[0027] The guiding hole 240 penetrates through the upper and lower surfaces of the cargo rail 200. The guiding block 320 is connected to the lower surface of the pushing seat 300. The guiding block 320 extends into the guiding hole 240, achieving the function of hiding the guiding block 320, and the guiding block 320 will not interfere with the goods. The abutting portion 310 is arranged on the guiding block 320. The upper end of the stop block 110 extends into the guiding hole 240 from bottom to top, ensuring that the upper end of the stop block 110 can abut on the abutting portion 310.

[0028] It can be understood that the guiding block 320 includes a bottom plate portion and two parallel vertical portions. The two vertical portions are distributed left and right and are perpendicular to the left and right directions. The upper ends of the two vertical portions are connected to the lower surface of the pushing seat 300, the lower end surfaces of the two vertical portions are connected to the upper surface of the bottom plate portion, the left and right ends of the bottom plate portion respectively extend to the outside of the two vertical portions, and the left and right ends of the bottom plate portion are both used to abut on the lower surface of the side wall of the guiding hole 240, and the two vertical portions respectively abut on the left and right side walls of the guiding hole 240.

[0029] Refer to Figure 3 , in this embodiment, the abutting portion 310 is connected to the front ends of the two vertical portions. An avoidance hole is arranged on the abutting portion 310. A hook portion is connected to the rear end of the stop block 110. The hook portion can be inserted into the avoidance hole and hooked on the bottom plate portion, thereby ensuring that the stop block 110 can limit the guiding block 320 in the guiding hole 240.

[0030] A roller 330 capable of lifting relative to the pushing seat 300 is arranged on the pushing seat 300. The pushing seat 300 is placed on the cargo rail 200 through the roller 330. The roller 330 can rotate, so that the frictional force received when the pushing seat 300 moves on the cargo rail 200 is small, and the pushing seat 300 can lift relative to the cargo rail 200 by a certain distance.

[0031] Refer to Figure 2 、 Figure 5 and Figure 6 , a convex block 250 is arranged on the rear side of the lower surface of the side wall of the guiding hole 240. The front end surface of the convex block 250 is an inclined surface, and the rear end surface of the convex block 250 is a vertical surface. Initially, the cargo rail 200 is directly above the bracket 100, and the convex block 250 is behind the stop block 110.

[0032] Drive the cargo rail 200 to move forward. The inclined surface of the bump 250 abuts against the lower part of the stop block 110, causing the cargo rail 200 to move upward relative to the bracket 100 until the bump 250 slides past the lower part of the stop block 110. At this time, the cargo rail 200 moves to the most forward position, and the cargo rail 200 is at the replenishment station. The rear end face of the bump 250 will abut against the front side face of the lower part of the stop block 110, and the lower part of the stop block 110 plays a role in preventing the bump 250 and the cargo rail 200 from moving backward. Finally, most of the area of the cargo rail 200 is limited in front of the bracket 100, and it is not necessary to keep the state of manually pulling the cargo rail 200 forward to replenish the cargo rail 200. When it is necessary to push the cargo rail 200 backward, after moving the cargo rail 200 upward by a certain distance, the cargo rail 200 can be pushed backward so that the bump 250 moves to the rear of the stop block 110.

[0033] Refer to Figure 3 、 Figure 4 and Figure 7 In another embodiment, the front end of the bracket 100 is detachably connected with a front plug 130. The stop block 110 is arranged on the upper surface of the front plug 130. The inclined surface of the bump 250 can abut against the rear end face of the front plug 130 and can slide past the upper surface of the front plug 130. The rear end face of the bump 250 can abut against the front end face of the front plug 130. The front end face of the front plug 130 cooperates with the rear end face of the bump 250, and the front plug 130 blocks the bump 250 and the cargo rail 200 from moving backward.

[0034] Refer to Figure 7 The bracket 100 includes a front plug 130, a rear plug, a connecting plate, and two parallel support plates 160. The two support plates 160 are distributed left and right. The plane where the support plates 160 are located is perpendicular to the left and right directions. The left and right ends of the front plug 130 are respectively detachably connected to the front ends of the two support plates 160. The left and right ends of the rear plug are respectively detachably connected to the rear ends of the two support plates 160. The left and right ends of the connecting plate are respectively detachably connected to the middle parts of the two support plates 160. The front plug 130, the rear plug, the connecting plate, and the two support plates 160 form a stable frame structure with relatively high structural strength, ensuring the reliability of its connection with the shelf or other external equipment, and ensuring its supporting ability and stability.

[0035] In this embodiment, the left and right ends of the front plug 130 and the front ends of the two support plates 160, the left and right ends of the rear plug and the rear ends of the two support plates 160, and the left and right ends of the connecting plate and the middle parts of the two support plates 160 are all connected by a buckle structure, which is convenient for the assembly and disassembly of the bracket 100.

[0036] Refer to Figure 1 、 Figure 2 and Figure 4, a gear plate and a push plate 340 are provided on the pushing seat 300. The gear plate is used to change the inclination angle of the push plate 340, and the pushing seat 300 pushes the goods through the push plate 340. First pin shaft parts are provided on both the left and right sides of the lower end of the push plate 340. The two first pin shaft parts are coaxially arranged, and the axial direction of the first pin shaft is the left-right direction. Two first pin holes are provided on the pushing seat 300. The two first pin holes are coaxially arranged. The two first pin shaft parts are respectively installed in the two first pin holes, so that the push plate 340 can swing or rotate on the pushing seat 300. The gear plate is perpendicular to the left-right direction. A plurality of limiting holes are provided on the gear plate. The center of the circle formed by the plurality of limiting holes is at the center of the first pin shaft part. A limiting shaft is provided on the push plate 340. The axial direction of the limiting shaft is the left-right direction. The limiting shaft is used to insert into the limiting holes. By inserting the limiting shaft into different positions of the limiting holes, the function of changing the backward inclination angle of the push plate 340 can be realized, so that the push plate 340 is suitable for pushing different goods.

[0037] Referring to Figure 3 and Figure 8 , in some of the embodiments, the thruster further includes a locking plate 500. The locking plate 500 is rotatably provided at the front end of the cargo rail 200. A buckle 510 is provided at one end of the locking plate 500, and a buckle groove 120 is provided at the front end of the bracket 100. The other end of the locking plate 500 is an actuating part 520. By actuating the actuating part 520, the locking plate 500 is driven to rotate. The buckle 510 is buckled on the buckle groove 120 to lock the cargo rail 200 on the bracket 100, avoiding the accidental forward movement of the cargo rail 200 on the bracket 100. When the locking plate 500 is driven to rotate in the reverse direction by actuating the actuating part 520, the buckle 510 is disengaged from the buckle groove 120, and there is no locking between the cargo rail 200 and the bracket 100, and the cargo rail 200 can move forward on the bracket 100.

[0038] In some of the embodiments, an elastic part 530 is provided on the locking plate 500. The elastic part 530 abuts against the cargo rail 200, so that in the natural state, the buckle 510 is in the posture of being buckled on the buckle groove 120. Without external force, the buckle 510 remains buckled on the buckle groove 120, so that the cargo rail 200 remains locked on the bracket 100.

[0039] Second pin shaft parts 540 are provided on both the left and right sides of the middle part of the locking plate 500. The two second pin shaft parts 540 are coaxially arranged, and the axial direction of the second pin shaft is the left-right direction. Two second pin holes are provided on the cargo rail 200. The two second pin holes are coaxially arranged. The two second pin shaft parts 540 are respectively installed in the two second pin holes, so that the locking plate 500 can swing or rotate on the cargo rail 200.

[0040] It can be understood that one end of the locking plate 500 faces backward, the buckle 510 is provided on the upper surface of one end of the locking plate 500, the rear end surface of the buckle 510 is an inclined surface, the notch of the buckle groove 120 faces downward, and the front side wall of the buckle groove 120 is provided with an inclined surface. When the cargo rail 200 carries the locking plate 500 and moves backward, the rear end surface of the buckle 510 cooperates with the inclined surface of the front side wall of the buckle groove 120, and the front side wall of the buckle groove 120 drives the locking plate 500 to rotate, so that the buckle 510 is buckled on the buckle groove 120.

[0041] In this embodiment, the buckle groove 120 is provided on the front plug 130 of the bracket 100, and the buckle groove 120 is located at the front part of the front plug 130.

[0042] It can be conceived that the lower end of the baffle 210 is connected to the front end of the cargo rail 200, the middle and upper parts of the baffle 210 are higher than the cargo rail 200 and are free ends. When the pushing seat 300 pushes the goods against the middle and upper parts of the baffle 210, the middle and upper parts of the baffle 210 are prone to bending.

[0043] Refer to Figure 3 and Figure 4 In some of these embodiments, the pusher further includes a reinforcing plate 600. The reinforcing plate 600 includes a connecting portion 610 and a pressing portion 620. The connecting portion 610 is connected to the lower end of the baffle 210, so that the entire reinforcing plate 600 is connected to the baffle 210. Of course, the connecting portion 610 can also be connected to the front end of the cargo rail 200.

[0044] The pressing portion 620 has elasticity. The pressing portion 620 is located in front of the baffle 210. The upper end of the pressing portion 620 abuts against the front surface of the baffle 210. The upper end of the pressing portion 620 applies a backward force to the middle and upper parts of the baffle 210, so that the anti-deformation ability of the baffle 210 is enhanced, and bending of the middle and upper parts of the baffle 210 is reduced or avoided.

[0045] It can be conceived that the connecting portion 610 and the lower end of the baffle 210 or the connecting portion 610 and the front end of the cargo rail 200 can be detachably connected. The connecting portion 610 is in the shape of a track, and the connecting portion 610 is slidably connected to the lower end of the baffle 210 or the front end of the cargo rail 200. The reinforcing plate 600 is made of metal processing. Ensure that the pressing portion 620 has sufficient elasticity.

[0046] Refer to Figure 7 In some of these embodiments, the front end of the bracket 100 is detachably connected with a front plug 130. Horizontal guiding flanges 140 are provided on the left and right side surfaces of the bracket 100. Notches 150 are formed between the front plug 130 and the two guiding flanges 140. Refer to Figure 6, first limit blocks 220 are provided at the rear ends on both the left and right sides of the cargo rail 200. The first limit blocks 220 can pass through the notch 150. The upper surface of the first limit block 220 is used to abut against the lower surface of the guiding flange 140, and the front surface of the first limit block 220 can abut against the rear end face of the front plug 130.

[0047] When installing the cargo rail 200 on the bracket 100, first place the cargo rail 200 above the bracket 100 with the first limit block 220 directly above the notch 150. Then, either swing the rear end of the cargo rail 200 downward or move the entire cargo rail 200 downward, so that the first limit block 220 passes through the notch 150 from top to bottom and the first limit block 220 is lower than the guiding flange 140. Next, move the cargo rail 200 backward until the first limit block 220 moves below the guiding flange 140 and can abut against the lower surface of the guiding flange 140. The first limit block 220 can prevent the cargo rail 200 from moving upward relative to the guiding flange 140 and the bracket 100.

[0048] When the cargo rail 200 and the first limit block 220 move forward, the front surface of the first limit block 220 abuts against the rear end face of the front plug 130, and the front plug 130 prevents the first limit block 220 and the cargo rail 200 from continuing to move forward, avoiding the cargo rail 200 from detaching from the bracket 100 due to excessive forward movement.

[0049] Part of the rear end face of the front plug 130 is outside the bracket 100 to ensure that the front surface of the first limit block 220 can abut against the rear end face of the front plug 130. The left and right ends of the front plug 130 are respectively connected to the front ends of two support plates 160 through snap structures.

[0050] Refer to Figure 7 , in some of the embodiments, the bracket 100 includes two parallel support plates 160 which are distributed left and right. The two support plates 160 are both perpendicular to the left - right direction. Two guiding flanges 140 are respectively arranged on two mutually - remote side surfaces of the two support plates 160. The two mutually - facing side surfaces of the two first limit blocks 220 respectively abut against the two mutually - remote side surfaces of the two support plates 160. The two first limit blocks 220 can prevent the cargo rail 200 from shifting left and right on the bracket 100.

[0051] Refer to Figure 6, second limit blocks 230 are provided at the rear ends on both the left and right sides of the cargo rail 200. The two second limit blocks 230 are respectively in front of the two first limit blocks 220. The upper surfaces of the two second limit blocks 230 are used to abut against the lower surface of the guiding flange 140, and the two second limit blocks 230 can also prevent the cargo rail 200 from moving upward relative to the guiding flange 140 and the bracket 100. The distance between the first limit block 220 and the second limit block 230 in the front-rear direction is equal to the length of the front plug 130 in the front-rear direction. When the rear end of the cargo rail 200 swings downward or the entire cargo rail 200 moves downward, the first limit block 220 passes through the notch 150, and the second limit block 230 moves downward to directly in front of the front plug 130.

[0052] The distance between the two opposite side surfaces of the two second limit blocks 230 is greater than the distance between the two outer side surfaces of the two support plates 160, so that the two second limit blocks 230 can be respectively arranged outside the two support plates 160; the distance between the two opposite side surfaces of the two second limit blocks 230 is greater than or equal to the distance between the left and right side surfaces of the front plug 130, so that the two second limit blocks 230 can slide past the left and right side surfaces of the front plug 130, and further enable the two second limit blocks 230 to move backward to directly below the two guiding flanges 140.

[0053] Referring to Figures 1 to 4 , in some of the embodiments, the elastic member 400 is a spring. The two ends of the elastic member 400 are respectively connected to the pushing seat 300 and the front end of the cargo rail 200. When the pushing seat 300 moves toward the rear end of the cargo rail 200, the elastic member 400 is stretched and stores energy, and when the elastic member 400 shortens, it can drive the pushing seat 300 toward the front end of the cargo rail 200.

[0054] A receiving groove is provided on the pushing seat 300. Initially, the elastic member 400 is in a coiled shape and is arranged in the receiving groove, and the receiving groove serves to receive and protect the elastic member 400.

[0055] In another embodiment, the elastic member 400 can also be a tension spring or a compression spring.

[0056] Referring to Figure 1 , in some of the embodiments, the pusher further includes a left side plate 700 and a right side plate 800. The left side plate 700 and the right side plate 800 are respectively distributed on the left and right sides of the cargo rail 200. The left side plate 700 and the right side plate 800 are respectively used to block the left and right sides of the goods, so as to prevent the goods from falling off the cargo rail 200 due to the left-right offset of the goods on the cargo rail 200, and ensure the stability of the goods on the pusher.

[0057] The left side plate 700 and the right side plate 800 are both connected to the cargo rail 200 through insertion rods. By adjusting the depth of the insertion rods inserted into the cargo rail 200, the distance between the cargo rail 200 and the left side plate 700 and the right side plate 800 is adjusted, that is, the distance between the left side plate 700 and the right side plate 800 is adjusted, so that the left side plate 700 and the right side plate 800 are applicable to defining goods of different widths.

[0058] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0059] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can also make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
