Description
Technical Field
[0001] This utility model relates to a push-pull table, and more particularly to a push-pull table with a locking function. Background Technology
[0002] Push-pull shelves can be moved horizontally, solving the inconvenience of traditional fixed shelves when retrieving goods. They are especially suitable for storing and retrieving goods deep within deep shelving units (such as drive-in racks and heavy-duty shelving units), allowing goods to be easily pulled from the back of the rack to the front, reducing manual bending and leaning operations, and improving work efficiency and safety. Push-pull shelves should be designed with a locking function to prevent them from moving forward and extending on their own. Utility Model Content
[0003] The purpose of this invention is to provide a push-pull table to solve the problem of the table extending forward on its own.
[0004] According to an embodiment of this utility model, the push-pull platform has a front-to-back direction in the horizontal plane and a vertical direction in the vertical plane. The push-pull platform includes a bracket, a platform, and a forward locking mechanism. The bracket is used to fix the push-pull platform. The platform is disposed on the upper side of the bracket and can move forward and backward relative to the bracket. The forward locking mechanism includes a limiting rod and a limiting groove. The limiting rod is disposed on the lower side of the platform, and the limiting groove is disposed on the bracket. The limiting groove has a limiting groove facing upward. The limiting rod has an opening and a locking position. The locking position is located below the unlocking position. In the locking position, the limiting rod is inserted into the limiting groove, which prevents the limiting rod from moving forward, thus preventing the platform from advancing relative to the bracket. When the limiting rod moves upward from the locking position to the unlocking position, it disengages from the limiting groove, releasing the obstruction and allowing the platform to advance relative to the bracket.
[0005] In one or more embodiments, the limiting groove member is further provided with a guide surface that extends forward and downward from the groove opening. The platform moves backward relative to the bracket, causing the limiting rod to abut against the guide surface and slide backward and upward along the guide surface, thereby guiding the limiting rod to reach the groove opening and fall into the limiting groove, so that the limiting rod is located in the locking position.
[0006] In one or more embodiments, the platform is provided with a support groove, the limiting rod is inserted into the support groove, and the limiting rod is supported at the bottom of the support groove under the action of gravity; the limiting rod moves upward relative to the support groove under the action of external force, so that the limiting rod moves upward from the locked position to the unlocked position; the limiting rod moves downward relative to the support groove under the action of gravity, so that the limiting rod falls into the limiting groove from the groove opening; when the limiting rod slides backward and upward along the guide surface, the guide surface supports the limiting rod to move upward relative to the support groove.
[0007] In one or more embodiments, the support groove extends in a vertical direction, the support groove blocks the movement of the limiting rod in a front-back direction, and allows the limiting rod to move in a vertical direction.
[0008] In one or more embodiments, the limiting rod is inserted into the limiting groove at the locking position, and the limiting groove also prevents the limiting rod from moving backward, thereby preventing the platform from retracting relative to the bracket.
[0009] In one or more embodiments, the limiting groove is located at the front of the bracket, such that the limiting rod is located at the front of the bracket in the locked position, so that the limiting rod can be manipulated to move to the unlocked position.
[0010] In one or more embodiments, the push-pull platform also has a left-right direction in the horizontal plane. The platform has a first left side plate on the left and a first right side plate on the right. Both the first left side plate and the first right side plate are perpendicular to the left-right direction. Both the first left side plate and the first right side plate are provided with the support groove. The limiting rod extends in the left-right direction. The left end of the limiting rod is inserted into the support groove of the first left side plate, and the right end of the limiting rod is inserted into the support groove of the first right side plate.
[0011] In one or more embodiments, the bracket has a second left side plate on the left and a second right side plate on the right. Both the second left side plate and the second right side plate are perpendicular to the left and right directions. The second left side plate is located to the left of the first left side plate, and the second right side plate is located to the right of the first right side plate. Slide rails are provided between the second left side plate and the first left side plate, and between the second right side plate and the first right side plate, so that the platform can move forward and backward relative to the bracket.
[0012] In one or more embodiments, the second left side plate is provided with a second connecting arm protruding to the right to support the limiting groove, such that the limiting groove of the second left side plate is located on the right side of the first left side plate to cooperate with the left end of the limiting rod; the second right side plate is provided with a second connecting arm protruding to the left to support the limiting groove, such that the limiting groove of the second right side plate is located on the left side of the first right side plate to cooperate with the right end of the limiting rod; both the limiting groove of the second left side plate and the limiting groove of the second right side plate are perpendicular to the left-right direction.
[0013] In one or more embodiments, the first left side plate is provided with a first connecting arm protruding to the left to connect to a left sliding plate, the left sliding plate being perpendicular to the left-right direction and attached to the left side of the second left side plate; the first right side plate is provided with a first connecting arm protruding to the right to connect to a right sliding plate, the right sliding plate being perpendicular to the left-right direction and attached to the right side of the second right side plate; when the platform moves back and forth relative to the bracket, the left sliding plate slides along the second left side plate, and the right sliding plate slides along the second right side plate.
[0014] The embodiments of this utility model have at least one of the following beneficial effects:
[0015] When the limit rod is in the locked position, it engages with the limit groove, preventing the limit rod from moving forward. The platform containing the limit rod cannot move forward relative to the bracket containing the limit groove. When the forward locking mechanism is locked, it prevents the platform from moving forward relative to the bracket, thus preventing the platform from extending forward on its own. As the limit rod moves upward from the locked position to the unlocked position, it disengages from the groove opening, releasing the obstruction of the limit groove and allowing the limit rod to move forward relative to the limit groove. The platform containing the limit rod is also allowed to move forward relative to the bracket containing the limit groove. After the forward locking mechanism unlocks, it allows the platform to move forward relative to the bracket, thus extending forward. Attached Figure Description

[0052] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.
[0053] It should be noted that these and other accompanying drawings are merely examples and are not drawn to scale, and should not be used as a limitation on the scope of protection of this utility model.
[0054] The terms “first”, “second”, etc., are used interchangeably to distinguish one feature from another and are not intended to indicate that each feature must be located in the position shown in the figure in each embodiment.
[0055] like Figure 1 and Figure 2 As shown, the sliding platform has a front-to-back direction in the horizontal plane. Taking the direction of movement of platform 1 relative to bracket 2 as a reference, "front" refers to the direction of movement of platform 1 when it extends relative to bracket 2, that is, the direction of movement of platform 1 from... Figure 1 Location changed to Figure 2 The direction of movement in the position is "back," which is the opposite of "forward." The sliding table also has a vertical direction within the vertical plane, with the direction of gravity as the reference. "Down" refers to the direction in the same direction as gravity, and "up" refers to the direction opposite to gravity. The sliding table also has a horizontal direction within the horizontal plane. The horizontal direction is perpendicular to the aforementioned front-back and vertical directions, together forming the three-dimensional spatial coordinate system of the sliding table. "Left" refers to the left-hand direction when facing backward, and "right" is the opposite of "left."
[0056] like Figures 1 to 6 As shown, the sliding table includes a table 1 and a bracket 2.
[0057] like Figure 1 and Figure 2 As shown, bracket 2 is used to fix the push-pull table. Bracket 2 may be equipped with a second left side plate 21 and a second right side plate 22, as described later. Both the second left side plate 21 and the second right side plate 22 may have multiple hooks 23 arranged vertically on their rear sides. Each hook 23 can be inserted into... Figure 9A hanging hole 31 is provided on the front wall of the column 3, thereby fixing the bracket 2 to the column 3, and the entire push-pull table device is fixed to the column 3.
[0058] like Figures 1 to 5 As shown, the platform 1 is located on the upper side of the bracket 2 and can move forward and backward relative to the bracket 2. Figure 1 The diagram shows the platform 1 retracted into the bracket 2. Figure 2 The diagram shows the platform 1 extending forward beyond the bracket 2, with the platform 1 moving relative to the bracket 2. Figure 1 The state change shown is as follows: Figure 2 As shown, the platform 1 is retracted relative to the bracket 2. Figure 2 The state change shown is as follows: Figure 1 The state shown.
[0059] like Figure 4 and Figure 5 As shown, the push-pull platform also includes a forward locking mechanism 4. The forward locking mechanism 4 includes a limiting rod 41 and a limiting groove 42. The limiting rod 41 is disposed on the platform 1 and located on the lower side of the platform 1. The limiting rod 41 has a locking position and an unlocking position, with the locking position located below the unlocking position. Figure 4 and Figure 5 The diagram shows the limit rod 41 in the locked position. The limit groove 42 is provided on the bracket 2, and the limit groove 42 is provided with a limit groove 43. The limit groove 43 has a groove opening 44, which faces upward.
[0060] like Figure 4 and Figure 5 As shown, the limiting rod 41 is inserted into the limiting groove 43 in the locked position. The limiting groove 43 blocks the limiting rod 41 from moving forward. The limiting rod 41 is blocked by the limiting groove 43 on the front side, so that the limiting rod 41 cannot move forward relative to the limiting groove 43. The platform 1 where the limiting rod 41 is located cannot move forward relative to the bracket 2 where the limiting groove 43 is located. When the forward locking mechanism 4 is locked, it blocks the platform 1 from moving forward relative to the bracket 2, preventing the platform 1 from moving forward and extending relative to the bracket 2 on its own.
[0061] since Figure 4 and Figure 5 In the locked position shown, the limiting rod 41 moves upward to the unlocked position, causing the limiting rod 41 to disengage from the limiting groove 43 through the groove opening 44, releasing the limiting groove 43 from blocking the limiting rod 41. The limiting rod 41 moves upward from the groove opening 44 away from the limiting groove 43 and reaches the upper side of the limiting groove 43. The limiting rod 41 is no longer blocked by the limiting groove 43 on the front side, allowing the limiting rod 41 to move forward relative to the limiting groove 43. The platform 1 where the limiting rod 41 is located is allowed to move forward relative to the bracket 2 where the limiting groove 43 is located. After the forward locking mechanism 4 is unlocked, the platform 1 is allowed to move forward relative to the bracket 2, thus extending forward.
[0062] like Figure 4 and Figure 5 As shown, the limiting rod 41 is inserted into the limiting groove 43 in the locked position. The limiting groove 43 can also prevent the limiting rod 41 from moving backward. The limiting rod 41 is blocked by the limiting groove 43 on the rear side, so that the limiting rod 41 cannot move backward relative to the limiting groove 43. The platform 1 where the limiting rod 41 is located cannot move backward relative to the bracket 2 where the limiting groove 43 is located. When the forward locking mechanism 4 is locked, it also prevents the platform 1 from moving backward relative to the bracket 2, preventing the platform 1 from moving backward relative to the bracket 2 on its own.
[0063] like Figure 4 and Figure 5 As shown, the limiting groove 42 may also be provided with a guide surface 45, which extends forward and downward from the groove opening 44, and moves backward relative to the bracket 2 on the platform 1. Figure 2 The state change shown is as follows: Figure 1 In the indicated state, the platform 1 drives the limiting rod 41 to move backward, causing the limiting rod 41 to abut against the guide surface 45. While moving backward, the limiting rod 41 is also supported upward by the guide surface 45, allowing it to slide backward and upward along the guide surface 45. The limiting rod 41 slides to the top and rear edge of the guide surface 45. Driven by the platform 1, the limiting rod 41 continues to move backward until it reaches the slot opening 44 located at the rear of the top and rear edge of the guide surface 45, and falls into the limiting slot 43, placing the limiting rod 41 in the locked position. The platform 1 retracts relative to the bracket 2, and the guide surface 45 guides the limiting rod 41 to the slot opening 44 and into the limiting slot 43. Consequently, the platform 1 retracts back into the bracket 2, and the forward locking mechanism 4 automatically locks.
[0064] like Figure 4 , Figure 5 and Figure 7 As shown, the platform 1 can be provided with a support groove 46. The limiting rod 41 is inserted into the support groove 46. Under the action of gravity, the limiting rod 41 is supported at the bottom of the support groove 46. Under the action of gravity, the limiting rod 41 is held at the bottom of the support groove 46 and supported by the bottom of the support groove 46. To unlock the forward locking mechanism 4 in the locked state, the limiting rod 41 needs to overcome gravity under the action of external force and move upward relative to the support groove 46, so that the limiting rod 41 moves from the locked position to the unlocked position. Under the action of gravity, the limiting rod 41 is normally held in the lower locked position, and the forward locking mechanism 4 is normally held in the locked state. When the platform 1 moves backward relative to the bracket 2, and the guide surface 45 guides the limiting rod 41 to the slot opening 44, the limiting rod 41 moves downward relative to the support groove 46 under the action of gravity, so that the limiting rod 41 falls from the slot opening 44 into the limiting slot 43. When the limiting rod 41 slides backward and upward along the guide surface 45, the limiting rod 41 is supported upward by the guide surface 45 while moving backward, and the guide surface 45 supports the limiting rod 41 to move upward relative to the support groove 46.
[0065] like Figure 4 , Figure 5 and Figure 7 As shown, the support groove 46 extends vertically and blocks the limiting rod 41 from moving horizontally. The limiting rod 41 is blocked by the support groove 46 on both the front and rear sides, preventing it from moving forward or backward relative to the support groove 46. The support groove 46 allows the limiting rod 41 to move vertically. Figure 4 and Figure 5 As shown in the locked position, the limit rod 41 moves directly upward to the unlocked position, which is directly above the locked position.
[0066] like Figures 4 to 6 As shown, the limiting groove 43 can be located at the front of the bracket 2, so that the limiting rod 41 is located at the front of the bracket 2 in the locked position, which makes it easy for the limiting rod 41 to be manipulated to move to the unlocked position. The operator's hand can easily reach the limiting rod 41 at the front of the bracket 2 and move the limiting rod 41 to the upper side to the unlocked position. The unlocking operation of the forward locking mechanism 4 in the locked state is simple and convenient.
[0067] like Figures 4 to 6 As shown, the platform 1 may have a first left side plate 11 on the left and a first right side plate 12 on the right. The three-dimensional structure of the first right side plate 12 and related components is shown in... Figure 7 As shown, the first left side plate 11 and related components are symmetrical with the first right side plate 12 and related components about a central plane, which is perpendicular to the left-right direction. Further integration Figure 7 Both the first left side plate 11 and the first right side plate 12 are perpendicular to the left-right direction. The first left side plate 11 and the first right side plate 12 can extend downwards from the bottom surface of the platform 1 in the vertical direction. Both the first left side plate 11 and the first right side plate 12 can be provided with a fixedly connected connecting plate 13, which is perpendicular to the vertical direction. The platform 1 can be supported on the upper side of the connecting plate 13. Both the first left side plate 11 and the first right side plate 12 can be provided with the aforementioned support groove 46. The limiting rod 41 extends in the left-right direction, with its left end inserted into the support groove 46 of the first left side plate 11 and its right end inserted into the support groove 46 of the first right side plate 12.
[0068] like Figure 4 and Figure 5 As shown, the support groove 46 can pass through the first left side plate 11 and the first right side plate 12. The left end of the limiting rod 41 is inserted into the support groove 46 of the first left side plate 11 and passes out from the left side of the first left side plate 11. The right end of the limiting rod 41 is inserted into the support groove 46 of the first right side plate 12 and passes out from the right side of the first right side plate 12. The end of the limiting rod 41 that passes out of the first left side plate 11 and the first right side plate 12 can be connected to a limiting nut to prevent the limiting rod 41 from moving in the left and right directions and disengaging from the support groove 46.
[0069] like Figures 1 to 6 As shown, the bracket 2 may have a second left side plate 21 on the left and a second right side plate 22 on the right. The second left side plate 21 and the second right side plate 22 may be fixedly connected by a plate beam 24 extending in the left-right direction to form the frame structure of the bracket 2. The second left side plate 21 and the second right side plate 22 may both be perpendicular to the left-right direction. The second left side plate 21 is located to the left of the first left side plate 11 and has a left-right gap. The second right side plate 22 is located to the right of the first right side plate 12 and has a left-right gap. The left-right gap between the second left side plate 21 and the first left side plate 11, and the left-right gap between the second right side plate 22 and the first right side plate 12 are both provided with slide rails 5, so that the platform 1 can slide back and forth relative to the bracket 2 to move forward and backward.
[0070] like Figures 3 to 6 As shown, the second left side plate 21 may be provided with a second connecting arm 25 supporting a limiting groove 42. The second connecting arm 25 of the second left side plate 21 protrudes to the right from the second left side plate 21, so that the limiting groove 42 of the second left side plate 21 is located on the right side of the first left side plate 11, thereby engaging with the left end of the limiting rod 41 as described above. Similarly, the second right side plate 22 may be provided with a second connecting arm 25 supporting a limiting groove 42. The second connecting arm 25 of the second right side plate 22 protrudes to the left from the second right side plate 22, so that the limiting groove 42 of the second right side plate 22 is located on the left side of the first right side plate 12, thereby engaging with the right end of the limiting rod 41 as described above. The second connecting arm 25 may be located at the bottom of the second left side plate 21 and the second right side plate 22 and perpendicular to the vertical direction. The limiting groove 42 of the second left side plate 21 and the limiting groove 42 of the second right side plate 22 may both be plates perpendicular to the horizontal direction, and the limiting groove 42 may protrude upward from the second connecting arm 25 in the vertical direction.
[0071] like Figures 1 to 3 as well as Figures 5 to 8As shown, the first left side panel 11 may be provided with a first connecting arm 14 to connect to the left slide plate 15. The first connecting arm 14 of the first left side panel 11 protrudes to the left from the first left side panel 11, so that the left slide plate 15 is located on the left side of the second left side panel 21. The left slide plate 15 is perpendicular to the left and right direction and is attached to the left side of the second left side panel 21. Similarly, the first right side panel 12 may be provided with a first connecting arm 14 to connect to the right slide plate 16. The first connecting arm 14 of the first right side panel 12 protrudes to the right from the first right side panel 12, so that the right slide plate 16 is located on the right side of the second right side panel 22. The right slide plate 16 is perpendicular to the left and right direction and is attached to the right side of the second right side panel 22. When the platform 1 moves back and forth relative to the bracket 2, the left slide plate 15 slides along the second left side panel 21, and the right slide plate 16 slides along the second right side panel 22. The left slide plate 15 is attached to the left side of the second left side panel 21, and the right slide plate 16 is attached to the right side of the second right side panel 22, preventing the platform 1 from swaying in the left and right direction relative to the bracket 2. The first connecting arm 14 may be located on top of the first left side plate 11 and the first right side plate 12 and perpendicular to the vertical direction. The left sliding plate 15 and the right sliding plate 16 may extend downward from the first connecting arm 14 in the vertical direction. The first connecting arm 14 may be part of the aforementioned connecting plate 13 and is supported on the lower side of the platform 1.
[0072] like Figures 4 to 6 As shown, a reinforcing rib 17 can be provided on the bottom surface of the platform 1 to improve the strength of the platform 1.
[0073] like Figures 1 to 3 As shown, the platform 1 may also be provided with a rear baffle 18. The rear baffle 18 is perpendicular to the front and back direction and protrudes upward from the rear side of the platform 1 in the vertical direction. The rear baffle 18 prevents items placed on the platform 1 from tipping over or falling off.
[0074] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention.
