Description

Technical Field

[0001] This application relates to the field of height adjustment technology, and in particular to a height adjustment device and storage container. Background Technology

[0002] The current storage repository is a three-dimensional storage grid structure. The storage grid is typically enclosed by interconnected columns and tracks, forming a frame structure. At the top of the storage grid is the top grid track, on which vehicles or robots are positioned. These vehicles or robots can move along the top grid track to pick up, transport, and place components stored in the storage grid. Typically, the top grid track must be horizontal to ensure the stability of the vehicles or robots as they move along it.

[0003] Currently, during the construction of storage facilities, the pillars are typically fixed to the ground using anchors. However, uneven ground often leads to inconsistent pillar heights, causing the top grid track to have an angle that prevents vehicles or robots from moving properly. Furthermore, current anchors do not allow for convenient adjustment of pillar height, making it difficult to ensure the levelness of the top grid track. Utility Model Content

[0004] Therefore, it is necessary to provide a height adjustment device and storage unit to address the problem that the height of the uprights cannot be adjusted using the foundation of the storage unit. This device can convert rotational motion into linear motion to achieve height adjustment, ensure the accuracy of the height adjustment, and facilitate the adjustment of the height of the uprights of the storage unit, thereby ensuring the levelness of the track at the top of the storage unit.

[0005] A height adjustment device, comprising:

[0006] A height adjustment structure includes a support base, an adjusting sleeve, a floating top seat, and a locking assembly. The adjusting sleeve is rotatably mounted on the support base in a first direction. The upper surface of the adjusting sleeve has a first mating surface that spirals upwards in a second direction. The floating top seat is movably fitted onto the support base and located above the adjusting sleeve. The upper surface of the floating top seat has a second mating surface corresponding to the first mating surface. The second mating surface spirals upwards in a second direction and can abut against the first mating surface. The locking assembly is disposed on both the adjusting sleeve and the support base to allow the adjusting sleeve to rotate in the first direction and restrict its rotation in the second direction.

[0007] An adjusting wrench is partially disposed around the adjusting sleeve. The adjusting wrench can drive the adjusting sleeve to rotate around a first direction, thereby driving the adjusting sleeve to lift the second mating surface through the first mating surface, thus causing the floating top seat to rise relative to the support base.

[0008] In one embodiment of this application, the outer wall of the adjusting sleeve has a plurality of positioning protrusions spaced apart in the circumferential direction, and a positioning groove is formed between two adjacent positioning protrusions.

[0009] The adjusting wrench has multiple mating protrusions, which are spaced apart along the circumference of the adjusting sleeve, and two adjacent mating protrusions form a mating groove.

[0010] When the adjusting wrench is engaged with the adjusting sleeve, the mating protrusion is embedded in the positioning groove, the mating groove accommodates the positioning protrusion, and the adjusting wrench drives the adjusting sleeve to rotate around the first direction through the contact between the positioning protrusion and the mating protrusion.

[0011] In one embodiment of this application, the surface of the mating protrusion facing the adjusting sleeve has a first abutting surface, which is used to abut against the outer surface of the adjusting sleeve;

[0012] And / or, the bottom wall of the mating groove has a second abutting surface, the second abutting surface being used to abut against the surface of the positioning protrusion facing the adjusting wrench;

[0013] And / or, the sidewall of the mating protrusion is the third abutment surface, the sidewall of the positioning protrusion is the fourth abutment surface, and when the adjusting wrench is engaged with the adjusting sleeve, the third abutment surface can abut against the fourth abutment surface;

[0014] And / or, the adjusting wrench includes an operating handle and a support portion, the support portion being disposed at one end of the operating handle, and a plurality of the mating protrusions being spaced apart along the circumference of the adjusting sleeve on the surface of the support portion facing the adjusting sleeve.

[0015] In one embodiment of this application, the support base includes a support seat and a support column. The support column is disposed vertically on the support seat. The adjusting sleeve is rotatably fitted onto the support column in a first direction. The floating top seat is movably disposed on the support column.

[0016] In one embodiment of this application, the outer surface of the support column has a first guide portion extending in a vertical direction, and the inner surface of the floating top seat has a second guide portion that cooperates with the first guide portion;

[0017] The second guide part cooperates with the first guide part to guide the rise of the floating top seat.

[0018] In one embodiment of this application, the locking component includes a first locking tooth and a second locking tooth. The first locking tooth is disposed on the adjusting sleeve, and the second locking tooth is disposed on the support base. The second locking tooth is correspondingly disposed and engaged with the first locking tooth.

[0019] The engagement between the first locking tooth and the second locking tooth allows the adjusting sleeve to move in a first direction and prevents the adjusting sleeve from moving in a second direction.

[0020] In one embodiment of this application, the first locking tooth and the second locking tooth are arranged in a ring, or the first locking tooth and the second locking tooth are partial teeth;

[0021] And / or, the first locking tooth is disposed on the inner wall of the adjusting sleeve, and the second locking tooth is disposed on the outer wall of the support column; or, the first locking tooth is disposed on the bottom of the adjusting sleeve, and the second locking tooth is disposed on the support base and located on the outer side of the support column.

[0022] In one embodiment of this application, the first locking tooth has a guide surface and a stop surface. The guide surface is inclined toward the adjusting sleeve about the first direction, and the stop surface is inclined in the vertical direction or about the first direction. The stop surface is used to stop the second locking tooth from moving about the second direction.

[0023] The structure of the second locking tooth is the same as that of the first locking tooth.

[0024] In one embodiment of this application, the top of the floating top seat has a support surface, which is used to support the mounting column;

[0025] And / or, the height adjustment structure further includes an elastic element disposed in the support column, and the elastic element abuts against the support column and the floating top seat to elastically support the floating top seat;

[0026] And / or, the height adjustment structure further includes a plurality of legs, which are evenly distributed at the bottom of the support base.

[0027] A storage container includes a storage frame and a plurality of height adjustment devices as described in any of the above technical features. The storage frame includes a plurality of columns and tracks, the columns being arranged vertically and the tracks being arranged horizontally and longitudinally. The columns and the tracks are joined together to form the storage frame.

[0028] At least some of the columns are provided with a height adjustment device at their bottom;

[0029] Each of the height adjustment devices raises the column to the same and / or different heights, so that the track at the top is in a horizontal state.

[0030] By adopting the above technical solution, this application has at least the following technical effects:

[0031] The present application discloses a height adjustment device and a storage unit. In the height adjustment device, an adjusting sleeve is rotatably mounted on a support base in a first direction, and a floating top seat is movably mounted on the support base and positioned above the adjusting sleeve. The upper surface of the adjusting sleeve has a first mating surface, and the lower surface of the floating top seat has a second mating surface. The first and second mating surfaces are opposite to each other and spiral upwards in a second direction. A locking assembly is disposed on the support base and the adjusting sleeve, allowing the adjusting sleeve to rotate in the first direction while restricting its rotation in the second direction. An adjusting wrench is disposed around the periphery of the adjusting sleeve. When the adjusting wrench is rotated, it drives the adjusting sleeve to rotate in the first direction, thereby allowing the adjusting sleeve to gradually lift the second mating surface through the first mating surface, thus raising the floating top seat relative to the support base. When the floating top seat rises to the desired position, the adjusting wrench stops driving the adjusting sleeve to rotate. At this time, the locking assembly locks the adjusting sleeve, keeping the adjusting sleeve and the floating top seat at the current height, thus completing the height adjustment of the floating top seat.

[0032] This height adjustment device features a spirally rising first and second mating surfaces on the surfaces of the adjusting sleeve and the floating top seat. When the adjusting sleeve is rotated in a first direction using an adjusting wrench, the adjusting sleeve, through the engagement of the spirally rising first and second mating surfaces, can lift the floating top seat, allowing it to rise relative to the support base. This adjusts the height of the floating top seat. A locking assembly reliably locks the adjusting sleeve, preventing the floating top seat from descending under external force and ensuring the accuracy of the height adjustment. Thus, with the bottom of the floating top seat supporting the column, the height adjustment device can adjust the column height, facilitating the adjustment of the column height in the storage unit and ensuring the levelness of the track at the top of the storage unit.

[0046] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0047] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0048] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0051] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0052] Understandably, currently, when building storage facilities, the pillars are typically fixed to the ground using anchors. However, uneven ground often leads to inconsistent pillar heights, causing the top grid track to have an angle that prevents vehicles or robots from moving properly. Furthermore, current anchors do not allow for easy adjustment of pillar height, making it difficult to ensure the levelness of the top grid track.

[0053] For this purpose, please refer to Figures 1 to 3 This application provides a novel height adjustment device 10. Figure 1 This is a schematic diagram of a height adjustment device 10 according to an embodiment of this application. Figure 2 for Figure 1 The diagram shown illustrates the application of the height adjustment device 10 to the storage warehouse. Figure 3 for Figure 2The image shows a partial enlarged view of the storage unit at point A. The height adjustment device 10 of this application is disposed at the bottom of the component to be adjusted, enabling height adjustment of the component to ensure that the tops of each component are at the same level.

[0054] In this embodiment, the height adjustment device 10 is applied in the storage unit. The component to be adjusted refers to the uprights 301 in the storage frame 30 of the storage unit. The height adjustment device 10 is disposed at the bottom of the uprights 301 to adjust the height of the uprights 301 so that the tops of all uprights 301 are at the same level, thereby adjusting the level of the top of the storage frame 30. Of course, in other embodiments of this application, the height adjustment device 10 can also be applied to the bottom of various devices or apparatuses that require level adjustment to adjust the level of the top of the corresponding device or apparatus.

[0055] To better illustrate the structure of the height adjustment device 10, the structure of the storage compartment will be briefly described here. See sections 1 to 12. Figure 3 The storage warehouse includes a storage frame 30 and a height adjustment device 10 as described in this application. The storage frame 30 includes multiple columns 301 and tracks 302. The columns 301 are arranged vertically, and the tracks 302 are arranged horizontally and vertically to form a grid structure. The columns 301 and tracks 302 are joined together to form the storage frame 30. The storage warehouse uses the storage frame 30 to store goods, etc. Furthermore, vehicles or robots can travel on the tracks 302 to store goods, etc., in or retrieve goods from the storage frame 30.

[0056] The storage frame 30 is placed on the ground 40 of the storage unit. Generally, the ground 40 of the storage unit is a cement surface, tile surface, or ceramic tile surface, etc. During construction, the ground 40 of the storage unit is required to be flat; that is, the ground 40 should not have any unevenness or potholes. Furthermore, because the storage unit is a large-scale structure, unevenness of the ground 40 cannot be effectively avoided, for example… Figure 6 In the scenario shown, there will be a difference in terrain between the leftmost and rightmost edges of the storage unit, such as the left being higher than the right.

[0057] After using the column 301 to support the track 302, the entire track 302 will also have unevenness, which will affect the movement of vehicles or robots. If columns of different sizes are used to support the track to ensure its levelness, this will increase the complexity of the storage unit structure and make the storage unit difficult to build. Therefore, this application provides a height adjustment device 10 at the bottom of the column 301, that is, the height adjustment device 10 of this application replaces the current base in the storage unit to realize the height adjustment of the column 301.

[0058] In this way, a height adjustment device 10 can be installed at the bottom of each column 301, or a height adjustment device 10 can be installed at the bottom of any column 301 whose height needs to be adjusted. The height adjustment device 10 can drive the column 301 to rise, thereby adjusting the position of the top of the column 301 so that the tops of all columns 301 are on the same horizontal plane, thus ensuring that the track 302 at the top of each column 301 is horizontal. This achieves the purpose of adjusting the levelness of the track 302 at the top of the column 301, and eliminates the need to use columns 301 of different sizes, facilitating the construction of the storage unit. How the height adjustment device 10 adjusts the top position of the column 301 and the levelness of the track 302 will be mentioned later.

[0059] The height adjustment device 10 of this application can convert rotational motion into linear motion to achieve height adjustment and ensure the accuracy of height adjustment. Furthermore, after supporting the column 301, the height adjustment device 10 can also easily adjust the height of the storage container column 301, thereby ensuring the levelness of the track 302 at the top of the storage container. The specific structure of the height adjustment device 10 in some embodiments is described below.

[0060] See Figures 1 to 5 In one embodiment, the height adjustment device 10 includes a height adjustment structure 100 and an adjustment wrench 200. The height adjustment structure 100 includes a support base 110, an adjustment sleeve 120, a floating top seat 130, and a locking assembly 140. The adjustment sleeve 120 is rotatably disposed on the support base 110 about a first direction. The upper surface of the adjustment sleeve 120 has a first mating surface 121 that spirals upward about a second direction. The floating top seat 130 is movably sleeved on the support base 110 and located above the adjustment sleeve 120. The upper surface of the floating top seat 130 has a second mating surface 131 that corresponds to the first mating surface 121. The second mating surface 131 spirals upward about a second direction and can abut against the first mating surface 121. The locking assembly 140 is disposed on the adjustment sleeve 120 and the support base 110 to allow the adjustment sleeve 120 to rotate about the first direction and restrict its rotation about the second direction.

[0061] The adjusting wrench 200 is partially surrounded by the adjusting sleeve 120. The adjusting wrench 200 can drive the adjusting sleeve 120 to rotate around the first direction, so as to drive the adjusting sleeve 120 to lift the second mating surface 131 through the first mating surface 121, thereby causing the floating top seat 130 to rise relative to the support base 110. Figure 4 for Figure 1 A schematic diagram of the height adjustment structure 100 in the height adjustment device 10 shown. Figure 5 for Figure 1 A schematic diagram of the adjusting wrench 200 in the height adjusting device 10 shown.

[0062] The height adjustment structure 100 is installed on the ground 40 of the storage warehouse. The top of the height adjustment structure 100 supports the column 301. That is, the height adjustment structure 100 is located between the ground 40 and the column 301. The column 301 extends in the vertical direction (actually the height direction), and the tops of multiple columns 301 are respectively connected to the rails 302. The adjustment wrench 200 is partially surrounded on the side of the height adjustment structure 100. When the user operates the adjustment wrench 200, the adjustment wrench 200 can drive the height adjustment structure 100 to move, thereby adjusting the height of the height adjustment structure 100, so that the height adjustment structure 100 can lift the column 301, thereby realizing the height adjustment of the column 301.

[0063] like Figure 6 As shown, Figure 6 To adopt Figure 4 The diagram illustrates an application scenario where the height adjustment structure 100 adjusts multiple columns 301. In a storage warehouse where the ground 40 is uneven, a height adjustment structure 100 is installed at the bottom of each column 301. The height adjustment structure 100 rises to different heights, thus lifting the columns 301 to different heights, bringing the tops of all columns 301 to the same plane. This adjusts the levelness of the tracks 302 supported by each column 301, ensuring the tracks 302 are horizontal.

[0064] Specifically, the ground level of the storage facility is higher on the left and lower on the right. Figure 6 The diagram illustrates four uprights 301 and four height adjustment structures 100. Of course, the storage unit can also use other numbers of uprights 301 and height adjustment structures 100, with the same principle. Figure 6 The four columns 301 and the four height adjustment structures 100 shown are based on the same principle, which will not be repeated hereafter.

[0065] The height adjustment structure 100 and the column 301 are in abutting relationship. When the height adjustment structure 100 is in its initial state, due to the inclination of the storage warehouse ground 40, the track 302 is also in an inclination state (left higher than right) after each height adjustment structure 100 supports the column 301. During adjustment, the user operates the adjustment wrench 200, which drives the height adjustment structure 100 to move, so that the height adjustment structure 100 drives the column 301 to rise, thereby adjusting the height of the column 301.

[0066] right Figure 6The height of the four height adjustment structures 100 is adjusted as follows: from left to right, the first height adjustment structure 100 can be left unchanged or only adjusted upwards to a first height; the second height adjustment structure 100 adjusts upwards to a second height; the third height adjustment structure 100 adjusts upwards to a third height; and the fourth height adjustment structure 100 adjusts upwards to a fourth height, with the fourth height > third height > second height > first height. In other words, the height of the four height adjustment structures 100 increases sequentially from left to right to adapt to the inclined ground 40, thereby raising the column 301 to the corresponding height to adjust the levelness of the track 302.

[0067] Understandably, since the height adjustment structure 100 and the column 301 are in a supporting relationship, when the previous height adjustment structure 100 drives the track 302 to rise via the column 301, the other columns 301 can be separated from or in contact with the height adjustment structure 100 to avoid the other height adjustment structures 100 being adjusted at the same time. Of course, the track 302 can also be kept horizontal, with a certain distance between each height adjustment structure 100 and the ground 40. Since the positions of the column 301 and the track 302 are fixed, the reaction force when the height adjustment structure 100 is adjusted causes the height adjustment structure 100 to gradually contact the ground 40.

[0068] Both of the above adjustment methods can achieve the adjustment of the levelness of track 302, and their principles are essentially the same. The following explanation will only use the example of the height adjustment structure 100 driving the column 301 to rise as an example. Furthermore, a level can be placed on track 302 to detect its levelness and determine whether track 302 is level. If track 302 is not level, the height adjustment structure 100 will continue to be adjusted until track 302 is level, thus ensuring the levelness of track 302.

[0069] The support base 110 serves as the fixed base for the entire height adjustment structure 100. Extending axially, the support base 110 supports all components of the height adjustment structure 100 and provides support for the storage column 301. The adjusting sleeve 120 is rotatably mounted on the support base 110 and can rotate relative to the support base 110 about a first direction. The floating top seat 130 is located on the support base 110 and above the adjusting sleeve 120. The floating top seat 130 can rise relative to the support base 110, such as... Figure 1 The arrows indicate the upward direction of the floating top seat 130, which can rise axially. When the adjusting sleeve 120 rotates around the first direction, it can drive the floating top seat 130 to rise relative to the support base 110. By converting rotational motion into linear motion, the height of the floating top seat 130 can be adjusted.

[0070] It is worth noting that the axial direction here refers to the height direction of the height adjustment structure 100, that is, the upward direction of the height adjustment structure 100 and the axial direction of the adjusting sleeve 120. The radial direction refers to the radius direction of the adjusting sleeve 120. Moreover, as... Figure 1 and Figure 4 As shown, the first direction is clockwise, and correspondingly, the second direction is opposite to the first direction, being counterclockwise. This orientation applies to all components of the height adjustment structure 100, and will not be described further below. Of course, in other embodiments of this application, the first direction may also be counterclockwise, and correspondingly, the second direction may be clockwise.

[0071] The surface of the adjusting sleeve 120 facing the floating top seat 130 is the upper surface, and the upper surface of the adjusting sleeve 120 has a first mating surface 121. The surface of the floating top seat 130 facing the adjusting sleeve 120 is the lower surface, and the lower surface of the floating top seat 130 has a second mating surface 131. The first mating surface 121 and the second mating surface 131 are opposite each other and abut against each other. Moreover, the first mating surface 121 and the second mating surface 131 spiral upwards in a second direction. That is, the first mating surface 121 and the second mating surface 131 are spirally arranged and spirally upwards in the second direction.

[0072] When the adjusting sleeve 120 rotates relative to the support base 110 in the first direction, the adjusting sleeve 120 can drive the first mating surface 121 to make a spiral downward movement. Since the first mating surface 121 abuts against the second mating surface 131, when the first mating surface 121 spirals downward, the surface at the lower position of the first mating surface 121 gradually separates from the second mating surface 131, and the surface at the higher position of the first mating surface 121 gradually contacts the second mating surface 131. In this way, the surface at the higher position of the first mating surface 121 can push the floating top seat 130 to move, thereby lifting the floating top seat 130. At this time, the floating top seat 130 can rise to a certain height relative to the support base 110.

[0073] When the adjusting sleeve 120 is continuously rotated around the first direction, the floating top seat 130 can be continuously lifted, allowing it to rise to the desired height. It is understood that the top of the floating top seat 130 can support the bottom of the column 301 or the bottom of other components to be adjusted (the following explanation uses the column 301 as an example only). When the adjusting sleeve 120 rotates around the first direction, the rotational motion is converted into linear motion through the first mating surface 121 and the second mating surface 131, driving the floating top seat 130 to rise relative to the support base 110, thereby lifting the column 301 and achieving level adjustment of the track 302 at the top of the column 301.

[0074] When the adjusting sleeve 120 and the floating top seat 130 are used to adjust the height, if the rotation of the adjusting sleeve 120 around the second direction is not limited, the floating top seat 130 will be pushed to rotate or move around the second direction by the cooperation of the second mating surface 131 and the first mating surface 121 under the action of external force (such as the pressure of the column 301), affecting the accuracy of height adjustment. Therefore, the height adjustment structure 100 of this application also includes a locking component 140, which is disposed between the adjusting sleeve 120 and the support base 110. The locking component 140 can lock the adjustment sleeve 120 relative to the support base 110 to rotate around the second direction, so that the floating top seat 130 can be kept in the current position, ensuring the accuracy and stability of height adjustment.

[0075] In other words, the locking component 140 can lock the adjusting sleeve 120 in the second direction, so that the adjusting sleeve 120 can only rotate around the first direction and cannot rotate around the second direction. The locking component 140 can lock the adjusting sleeve 120 in the second direction. When the height of the floating top seat 130 needs to be adjusted, rotating the adjusting sleeve 120 around the first direction will cause the floating top seat 130 to rise to the desired position. When the adjusting sleeve 120 stops rotating, the locking component 140 restricts the adjusting sleeve 120 from rotating around the second direction.

[0076] Furthermore, the adjusting wrench 200 can be partially surrounded on the outside of the adjusting sleeve 120 and connected to the adjusting sleeve 120. When the user operates the adjusting wrench 200, the adjusting wrench 200 can drive the adjusting sleeve 120 to rotate around the first direction. When the adjusting sleeve 120 rotates, the adjusting sleeve 120 contacts the second mating surface 131 of the floating top seat 130 through the first mating surface 121, and drives the second mating surface 131 to spiral upward around the second direction, so as to lift the floating top seat 130, so that the floating top seat 130 can rise a certain height relative to the support base 110.

[0077] It is worth noting that the height of the floating top seat 130 can be adjusted by rotating the adjusting sleeve 120 around the first direction by the adjusting wrench 200. Thus, the adjusting sleeve 120 can be gradually rotated according to the elevation of the height adjustment structure 100, thereby adjusting the height of the floating top seat 130, and consequently adjusting the top position of the column 301 to adjust the levelness of the track 302. Optionally, each height adjustment structure 100 can correspond to one adjusting wrench 200; of course, multiple height adjustment structures 100 can also share one adjusting wrench 200.

[0078] The height adjustment device 10 of the above embodiment has a spirally rising first mating surface 121 and a second mating surface 131 on the surfaces of the adjusting sleeve 120 and the floating top seat 130. When the adjusting sleeve 120 is driven to rotate around a first direction by the adjusting wrench 200, the adjusting sleeve 120 can lift the floating top seat 130 through the engagement of the spirally rising first mating surface 121 and the second mating surface 131, so that the floating top seat 130 can rise relative to the support base 110 to adjust the height of the floating top seat 130. The locking component 140 can reliably lock the adjusting sleeve 120 to prevent the floating top seat 130 from falling under the action of external force, thus ensuring the accuracy of the height adjustment device 10. In this way, after the bottom of the floating top seat 130 supports the column 301, the height adjustment device 10 can adjust the height of the column 301, thereby facilitating the adjustment of the height of the column 301 in the storage warehouse and ensuring the levelness of the track 302 at the top of the storage warehouse.

[0079] See Figure 1 , Figure 4 , Figures 7 to 10 In one embodiment, there are multiple first mating surfaces 121, which are evenly distributed circumferentially. The number of second mating surfaces 131 is the same as the number of first mating surfaces 121, and the second mating surfaces 131 are arranged in a one-to-one correspondence with the first mating surfaces 121. Figure 7 for Figure 4 The diagram shown is a schematic representation of the floating top mount 130 from one perspective. Figure 8 for Figure 7 The diagram shown is a schematic representation of the floating top mount 130 from another perspective. Figure 9 for Figure 8 The diagram shown is a schematic representation of the adjusting sleeve 120 from one perspective. Figure 10 for Figure 9 The diagram shows the adjusting sleeve 120 from another perspective. By employing a one-to-one correspondence between multiple first mating surfaces 121 and multiple second mating surfaces 131 between the adjusting sleeve 120 and the floating top seat 130, the stability of the floating top seat 130 during its ascent can be ensured.

[0080] See Figure 4 , Figures 7 to 9 For example, there are two first mating surfaces 121 and two second mating surfaces 131, with the two first mating surfaces 121 and the two second mating surfaces 131 symmetrically arranged. That is, the phase difference between the two first mating surfaces 121 is 180°, and the phase difference between the two second mating surfaces 131 is also 180°. The cooperation between the two first mating surfaces 121 and the two second mating surfaces 131 ensures the stability of the floating top seat 130 during lifting. Of course, in other embodiments of this application, the number of first mating surfaces 121 and second mating surfaces 131 may also be other.

[0081] See Figure 1 , Figure 4 and Figure 5 In one embodiment, the outer wall of the adjusting sleeve 120 has a plurality of circumferentially spaced positioning protrusions 122, and a positioning groove 123 is formed between two adjacent positioning protrusions 122. The adjusting wrench 200 has a plurality of mating protrusions 210, which are spaced circumferentially around the adjusting sleeve 120, and two adjacent mating protrusions 210 form a mating groove 220. When the adjusting wrench 200 is engaged with the adjusting sleeve 120, the mating protrusions 210 are embedded in the positioning groove 123, and the mating groove 220 accommodates the positioning protrusions 122. The adjusting wrench 200 drives the adjusting sleeve 120 to rotate around a first direction through the abutment between the positioning protrusions 122 and the mating protrusions 210.

[0082] When the adjusting wrench 200 is engaged with the adjusting sleeve 120, the engaging protrusion 210 of the adjusting wrench 200 is inserted into the engaging positioning groove 123 of the adjusting sleeve 120. At this time, the positioning protrusion 122 of the adjusting sleeve 120 is inserted into the engaging groove 220 of the adjusting sleeve 120. That is to say, when the adjusting wrench 200 is engaged with the adjusting sleeve 120, the adjusting wrench 200 is partially surrounded by the adjusting sleeve 120, and the multiple positioning protrusions 122 and the multiple engaging protrusions 210 are staggered.

[0083] When the user operates the adjusting wrench 200, the adjusting wrench 200 pushes the positioning protrusion 122 to rotate around the first direction through the cooperating protrusion 210, thereby driving the adjusting sleeve 120 to rotate around the first direction. When the adjusting sleeve 120 rotates, it can drive the second cooperating surface 131 to rise through the first mating surface 121, thereby driving the floating top seat 130 to rise. When the floating top seat 130 rises, it can lift the column 301 to adjust the position of the top of the column 301, thereby adjusting the levelness of the track 302 and keeping the track 302 in a horizontal state.

[0084] See Figure 1 , Figure 4 and Figure 5 In one embodiment, the surface of the mating protrusion 210 facing the adjusting sleeve 120 has a first abutting surface 211, which abuts against the outer surface of the adjusting sleeve 120. The mating protrusion 210 abuts against the outer surface of the adjusting sleeve 120 via the first abutting surface 211, ensuring that the mating protrusion 210 can accurately contact the adjusting sleeve 120 and that the adjusting wrench 200 can be installed in place. Optionally, the first abutting surface 211 is an arc-shaped surface.

[0085] See Figure 1 , Figure 4 and Figure 5In one embodiment, the bottom wall of the mating groove 220 has a second abutting surface 221, which abuts against the surface of the positioning protrusion 122 facing the adjusting wrench 200. The mating groove 220 abuts against the positioning protrusion 122 through the second abutting surface 221 of its bottom wall, ensuring that the positioning protrusion 122 can be accurately installed into the mating groove 220, and ensuring that the adjusting wrench 200 can be installed in place. Optionally, the second abutting surface 221 is an arc-shaped surface.

[0086] See Figure 1 , Figure 4 and Figure 5 In one embodiment, the sidewall of the mating protrusion 210 is a third abutment surface 212, and the sidewall of the positioning protrusion 122 is a fourth abutment surface 1221. When the adjusting wrench 200 is engaged with the adjusting sleeve 120, the third abutment surface 212 can abut against the fourth abutment surface 1221. The third abutment surface 212 and the fourth abutment surface 1221 are planar. The third abutment surface 212 of the mating protrusion 210 and the fourth abutment surface 1221 of the positioning protrusion 122 are arranged opposite to each other. After the adjusting wrench 200 is installed in the adjusting sleeve 120, the positioning protrusion 122 is installed in the mating groove 220, and the mating protrusion 210 is installed in the positioning groove 123. At this time, the third abutment surface 212 and the fourth abutment surface 1221 abut against each other. When the user operates the adjusting wrench 200, the adjusting wrench 200 can push the positioning protrusion 122 to rotate around the first direction through the contact between the third contact surface 212 and the fourth contact surface 1221, thereby driving the adjusting sleeve 120 to rotate around the first direction.

[0087] See Figure 1 , Figure 4 and Figure 5 In one embodiment, the adjusting wrench 200 includes an operating handle 230 and a support portion 240. The support portion 240 is disposed at one end of the operating handle 230, and a plurality of mating protrusions 210 are spaced apart along the circumference of the adjusting sleeve 120 on the surface of the support portion 240 facing the adjusting sleeve 120. The operating handle 230 is rod-shaped and serves as the handle of the adjusting wrench 200. The support portion 240 is one end of the operating handle 230 and supports the mating protrusions 210.

[0088] In this way, the user drives the operating handle 230 to rotate around the first direction. The operating handle 230 drives the mating protrusion 210 to rotate around the first direction through the support part 240. The mating protrusion 210, in turn, drives the adjusting sleeve 120 to rotate around the first direction through its engagement with the positioning protrusion 122, thus achieving the rotation of the adjusting sleeve 120. Optionally, the support part 240 is arranged in a ring shape. Optionally, the operating handle 230, the support part 240, and the mating protrusion 210 are integrated into a single structure to ensure the structural strength of the adjusting wrench 200.

[0089] See Figure 1 , Figure 4 and Figure 11 In one embodiment, the support base 110 includes a support seat 111 and a support column 112. The support column 112 is disposed vertically on the support seat 111. The adjusting sleeve 120 is rotatably disposed on the support column 112 around a first direction. The floating top seat 130 is movably disposed on the support column 112. Figure 11 for Figure 4 A schematic diagram of the support base 110 in the height adjustment structure 100 shown.

[0090] The support base 110 is divided into two parts: a support seat 111 and a support column 112. The support column 112 is cylindrical and is mounted on the support seat 111. The support seat 111 supports the support column 112 and other components of the height adjustment structure 100. It is worth noting that the shape of the support seat 111 is not limited in principle, as long as it can provide support. For example, the support seat 111 is square and protrudes circumferentially from the support column 112. Of course, in other embodiments of this application, the support seat 111 may also be circular or other shapes.

[0091] The support column 112 has a certain height along the axial direction. The adjusting sleeve 120 is sleeved on the support column 112, and the bottom of the adjusting sleeve 120 abuts against the support base 111. The floating top seat 130 is sleeved on the support column 112 and is located above the adjusting sleeve 120. Optionally, the support base 111 and the support column 112 are an integral structure. Of course, in other embodiments of this application, the support base 111 and the support column 112 can also be set separately and reliably fixed by welding, threaded connection, or other methods.

[0092] See Figure 1 , Figure 4 and Figure 7 In one embodiment, the surface of the support base 111 facing away from the support column 112 has multiple support columns 1111, which are evenly distributed and protrude. The multiple support columns 1111 are located at the bottom of the support base 111 and can contact the ground 40 to support the support base 111 on the ground 40. Furthermore, the even distribution of the multiple support columns 1111 at the bottom of the support base 111 provides stable support for the support base 111, thereby ensuring the overall stability of the height adjustment structure 100 and providing stable support for the floating top seat 130. Optionally, the support columns 1111 and the support base 111 are an integral structure and are located at the four corners of the support base 111 to provide stable support for the support base 111.

[0093] See Figure 1 , Figure 4 and Figure 7In one embodiment, the height adjustment structure 100 further includes a plurality of support legs 150, which are evenly distributed at the bottom of the support base 111. The support legs 150 are located at the bottom of the support base 111, and the support base 111 is stably supported through the cooperation of the support legs 150 with the support column 1111. Optionally, the number of support legs 150 is at least two sets, each set having two support legs 150, and the at least two sets of support legs 150 are arranged in a cross-shaped staggered pattern and fixed to the ground 40. Optionally, the support legs 150 are fixed to the ground 40 by expansion bolts or the like.

[0094] See Figure 8 and Figure 11 In one embodiment, the outer surface of the support column 112 has a first guide portion 1121 extending vertically, and the inner surface of the floating top seat 130 has a second guide portion 132 that cooperates with the first guide portion 1121. The second guide portion 132 cooperates with the first guide portion 1121 to guide the rising of the floating top seat 130. The first guide portion 1121 and the second guide portion 132 extend in the height direction.

[0095] The cooperation between the first guide portion 1121 and the second guide portion 132 limits the upward movement of the floating top seat 130, ensuring that the floating top seat 130 can only move upward and cannot rotate, thereby ensuring that the floating top seat 130 stably lifts the column 301. When the adjusting sleeve 120 is rotated, the adjusting sleeve 120 lifts the floating top seat 130 through the cooperation between the first mating surface 121 and the second mating surface 131. When the floating top seat 130 rises, it can move along the first guide portion 1121 through the second guide portion 132, preventing the floating top seat 130 from shifting during its rise, ensuring that the movement trajectory of the floating top seat 130 is accurate, and thus stably lifting the column 301.

[0096] For example, the first guide portion 1121 is a guide groove, and the second guide portion 132 is a guide protrusion. The guide protrusion protrudes from the inner wall of the floating top seat 130 and is slidably disposed in the guide groove. Of course, in other embodiments of this application, the first guide portion 1121 may also be a protruding guide protrusion, and the second guide portion 132 may be a guide groove.

[0097] See Figure 4 , Figures 9 to 11 In one embodiment, the locking assembly 140 includes a first locking tooth 141 and a second locking tooth 142. The first locking tooth 141 is disposed on the adjusting sleeve 120, and the second locking tooth 142 is disposed on the support base 110. The second locking tooth 142 is correspondingly disposed and engaged with the first locking tooth 141. The engagement between the first locking tooth 141 and the second locking tooth 142 allows the adjusting sleeve 120 to move around a first direction and prevents the adjusting sleeve 120 from moving around a second direction.

[0098] When the adjusting sleeve 120 rotates about a first direction, it can move along the first locking tooth 141 via the second locking tooth 142. When the adjusting sleeve 120 stops rotating, the first locking tooth 141 engages with the second locking tooth 142, which restricts the adjustment sleeve 120 from rotating about a second direction, thereby locking the adjusting sleeve 120 and keeping the floating top seat 130 in its current position, ensuring the accuracy and stability of height adjustment. Thus, the locking assembly 140 allows the adjusting sleeve 120 to rotate about a first direction while restricting its rotation about a second direction.

[0099] Furthermore, after the adjusting sleeve 120 rotates by an angle corresponding to the first locking tooth 141, the portion of the first mating surface 121 that contacts the second mating surface 131 rotates and rises to a certain height. This allows the first mating surface 121 to lift the second mating surface 131 to the corresponding height, thereby causing the floating top seat 130 to rise by the same height. In other words, after the first locking tooth 141 of the adjusting sleeve 120 engages with the second locking tooth 142 of the support base 110 once, the floating top seat 130 can rise by one unit. Thus, by quantifying and corresponding the rotation of the adjusting sleeve 120 to the rise of the floating top seat 130, the user can adjust the angle of the sleeve 120 according to the desired rise height, thereby adjusting the rise height of the floating top seat 130, making operation convenient for the user.

[0100] It is worth noting that the specific values ​​of the rotation angle corresponding to the first locking tooth 141 of the adjusting sleeve 120 and the rising height corresponding to the floating top seat 130 are not specifically explained here, but can be set according to the actual use scenario.

[0101] See Figure 4 , Figures 9 to 11 In one embodiment, the first locking tooth 141 and the second locking tooth 142 are arranged in a ring. That is, the first locking tooth 141 is arranged in a ring around the adjusting sleeve 120, and the second locking tooth 142 is arranged in a ring around the support base 110. The first locking tooth 141 and the second locking tooth 142 correspond one-to-one, so that when the adjusting sleeve 120 rotates, each of the first locking teeth 141 can engage with the second locking tooth 142 to achieve locking of the adjusting sleeve 120 when rotating in the second direction.

[0102] Of course, in other embodiments of this application, the first locking tooth 141 can be a partial tooth and the second locking tooth 142 can be an annular tooth, or the first locking tooth 141 can be an annular tooth and the second locking tooth 142 can be a partial tooth, or both the first locking tooth 141 and the second locking tooth 142 can be partial teeth. As long as the first locking tooth 141 and the second locking tooth 142 cooperate to achieve locking of the adjusting sleeve 120 rotating in the second direction, it is acceptable.

[0103] See Figure 4 , Figures 9 to 11 In one embodiment, a first locking tooth 141 is disposed at the bottom of the adjusting sleeve 120, and a second locking tooth 142 is disposed on the support base 111 and located outside the support column 112. That is, the first locking tooth 141 is located on the lower surface of the adjusting sleeve 120, and the second locking tooth 142 is located on the upper surface of the support base 111. After the adjusting sleeve 120 is fitted onto the support column 112, the first locking tooth 141 can engage with the second locking tooth 142 to achieve locking of the adjusting sleeve 120 during rotation in the second direction.

[0104] Of course, in other embodiments of this application, the first locking tooth 141 is disposed on the inner wall of the adjusting sleeve 120, and the second locking tooth 142 is disposed on the outer wall of the support column 112. That is, the first locking tooth 141 is located on the inner surface of the adjusting sleeve 120, and the second locking tooth 142 is located on the outer surface of the support column 112. After the adjusting sleeve 120 is fitted onto the support column 112, the first locking tooth 141 can engage with the second locking tooth 142 to achieve locking of the adjusting sleeve 120 when rotating in the second direction.

[0105] For example, the first locking tooth 141 is arranged in a ring at the bottom of the adjusting sleeve 120, and the second locking tooth 142 is arranged in a ring on the support base 111, with the first locking tooth 141 and the second locking tooth 142 correspondingly arranged. In this way, after the adjusting sleeve 120 rotates by an angle corresponding to the first locking tooth 141, the part of the first mating surface 121 that contacts the second mating surface 131 rises to a certain height, so as to quantify the rotation angle of the adjusting sleeve 120 into the rising height of the floating top seat 130.

[0106] In one embodiment, the first locking tooth 141 and the adjusting sleeve 120 are integrally formed, and the second locking tooth 142 and the support base 111 are integrally formed. That is, the first locking tooth 141 is directly machined on the bottom of the adjusting sleeve 120, and the second locking tooth 142 is directly machined on the support base 111 to ensure the structural strength of the first locking tooth 141 and the second locking tooth 142, thereby ensuring the locking effect of the locking assembly 140 on the adjusting sleeve 120 in the second direction.

[0107] See Figure 4 , Figures 9 to 12 In one embodiment, the second locking tooth 142 has a guide surface 1421 and a stop surface 1422. The guide surface 1421 is inclined toward the adjusting sleeve 120 about a first direction, and the stop surface 1422 is inclined in the vertical direction or about the first direction. The stop surface 1422 is used to stop the second locking tooth 142 from moving about a second direction. The structure of the first locking tooth 141 is the same as the structure of the second locking tooth 142. Figure 12 for Figure 4 A magnified view of the height adjustment structure 100 at point B.

[0108] See Figures 9 to 12 The second locking tooth 142 is disposed on the support base 111. The guide surface 1421 is inclined, tilting upwards in a first direction (from the lower right to the upper left). The stop surface 1422 is vertically disposed. When the first locking tooth 141 and the second locking tooth 142 are engaged, the surface of the first locking tooth 141 is in contact with the guide surface 1421 and the stop surface 1422. When the adjusting sleeve 120 rotates in the first direction, the first locking tooth 141 of the adjusting sleeve 120 can rotate along the guide surface 1421. When the adjusting sleeve 120 stops rotating, the first locking tooth 141 can contact the stop surface 1422, which restricts the adjustment sleeve 120 from rotating in a second direction.

[0109] See Figure 4 , Figure 7 In one embodiment, the floating top seat 130 has a support surface 133 at its top, which supports the mounting column 301. The floating top seat 130 provides stable support to the bottom of the column 301 through the support surface 133. Thus, when the adjusting sleeve 120 rotates, it drives the floating top seat 130 to rotate and rise, and the floating top seat 130 lifts the column 301 through the support surface 133, causing the column 301 to rise.

[0110] In one embodiment, the height adjustment structure 100 further includes an elastic element disposed in the support column 112. The elastic element abuts against the support column 112 and the floating top seat 130 to elastically support the floating top seat 130. The elastic element is located in the support column 112, and the bottom of the elastic element abuts against the support column 112, while the top of the elastic element abuts against the floating top seat 130 to elastically support the floating top seat 130.

[0111] Understandably, the elastic element is an energy storage component, initially inserted in a compressed state between the support column 112 and the floating top seat 130. When the height adjustment structure 100 is in its extreme adjustment position, the elastic element changes from a compressed state to a free state. Optionally, the elastic element can be a spring, bellows, elastic column, or other components capable of providing elastic support.

[0112] In the height adjustment device 10 of this application, the height adjustment structure 100 is located between the column 301 and the ground 40, and the adjustment wrench 200 is a cooperating mechanism. The operator operates the adjustment wrench 200 to cooperate with the adjustment sleeve 120, and through the cooperation of the positioning protrusion 122 and the cooperating protrusion 210, drives the adjustment sleeve 120 to rotate around a first direction. This, in turn, drives the floating top seat 130 to rise vertically, thereby supporting the column 301. Simultaneously, a height adjustment structure 100 is provided below each column 301. In this manner, the track 302 above multiple columns 301 can be made to a certain level. That is, by changing the top position of each column 301 in the storage frame 30, the levelness of the track 302 supported by the column 301 can be changed, ensuring that the entire track 302 is in a horizontal state.

[0113] When adjusting the height, the operator's adjusting wrench 200 has its mating protrusion 210 installed in the positioning groove 123 of the adjusting sleeve 120, and the adjusting sleeve 120 has its positioning protrusion 122 installed in the mating groove 220 of the adjusting wrench 200. Rotating the adjusting wrench 200 utilizes its lever arm to easily generate the required torque, driving the adjusting sleeve 120 to rotate in the first direction. Furthermore, the adjusting sleeve 120 and the support base 110 are engaged by the first locking tooth 141 and the second locking tooth 142. When the adjusting sleeve 120 rotates through a certain angle, the engagement between the first locking tooth 141 and the second locking tooth 142 prevents the adjusting sleeve 120 from rotating in the opposite direction, thus providing a locking function.

[0114] The height adjustment device 10 of this application has a spirally rising first mating surface 121 and a second mating surface 131 on the surfaces of the adjusting sleeve 120 and the floating top seat 130. When the adjusting sleeve 120 is driven to rotate around a first direction by the adjusting wrench 200, the adjusting sleeve 120 can lift the floating top seat 130 through the engagement of the spirally rising first mating surface 121 and the second mating surface 131, so that the floating top seat 130 can rise relative to the support base 110 to adjust the height of the floating top seat 130. The locking component 140 can reliably lock the adjusting sleeve 120 to prevent the floating top seat 130 from falling under the action of external force, thus ensuring the accuracy of the height adjustment device 10. In this way, after the bottom of the floating top seat 130 supports the column 301, the height adjustment device 10 can adjust the height of the column 301, thereby facilitating the adjustment of the height of the column 301 in the storage warehouse and ensuring the levelness of the track 302 at the top of the storage warehouse.

[0115] See Figures 1 to 3 , Figure 6This application also provides a storage container, including a storage frame 30 and a plurality of height adjustment devices 10 as described in any of the above embodiments. The storage frame 30 includes a plurality of columns 301 and tracks 302. The columns 301 are arranged vertically, and the tracks 302 are arranged horizontally and longitudinally. The columns 301 and tracks 302 are joined together to form the storage frame 30. At least some of the columns 301 are provided with a height adjustment device 10 at their bottoms. Each height adjustment device 10 raises the columns 301 to the same and / or different heights, so that the top track 302 is in a horizontal state.

[0116] To ensure that track 302 achieves a certain level of horizontality, a storage warehouse is constructed at a site with terrain differences. Figure 6 In the storage frame 30, the ground 40 is uneven, with a certain angle from left to right, and the left side is the highest and the right side is the lowest. This illustrates that four height adjustment structures 100 adjust the column 301 from left to right. The surface of the highest point of the ground 40 corresponding to the height adjustment structure 100 and its upper track 302 is used as the horizontal reference point. The height adjustment mechanisms of the remaining lower points within the storage frame 30 are adjusted. The operator drives the adjustment sleeve 120 to rotate using the adjustment wrench 200, causing the first mating surface 121 and the second mating surface 131 of the adjustment sleeve 120 to rotate, thereby lifting the floating top seat 130. The floating top seat 130 rises through the cooperation of the first guide part 1121 and the second guide part 132 until the column 301 drives the track 302 to rise to the reference horizontal point, at which point the adjustment of the height adjustment structure 100 is stopped.

[0117] In the storage container of this application, the storage frame 30 is formed by splicing multiple columns 301 and tracks 302. At least some of the columns 301 have a height adjustment structure 100 at their bottom, and are fixed to the ground 40 by the height adjustment structure 100.
