DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] Example 1

[0036] An embodiment of the present invention provides a storage rack, which includes a support assembly 1, a storage assembly 2 and a positioning assembly 3. The support assembly 1 includes a plurality of support rods 11 parallel to each other, the plurality of support rods 11 include at least one positioning rod 111, and the positioning rod 111 is configured with a plurality of locking portions 1111 distributed along the length direction of the positioning rod 111; the storage assembly 2 is arranged on the support assembly 1, and the edge of the storage assembly 2 is slidably matched with the plurality of support rods 11; the positioning assembly 3 is arranged on the storage assembly 2 and corresponds to the positioning rod 111, and the positioning assembly 3 includes a top rod 31, and the top rod 31 is configured such that its first end can be inserted into or disengaged from the corresponding locking portion 1111 to lock or unlock the position of the storage assembly 2 on the support assembly 1.

[0037] Specifically, the overall structure of the rack is as follows: Figure 1 As shown, the main structure includes a support component 1 and a storage component 2 arranged on the support component 1. Among them, the storage component 2 is used to directly place items. According to needs, the storage component 2 can be a box body, a flat plate and other structures. The support component 1 is composed of a plurality of support rods 11. The height of the storage component 2 can be adjusted according to needs. The support rods 11 are vertically arranged, and the storage component 2 can slide along the support rods 11 to adjust the height. At the same time, the plurality of support rods 11 include at least one positioning rod 111 provided with a locking portion 1111 structure. The locking portion 1111 on the positioning rod 111 is used to cooperate with the positioning component 3 on the storage component 2 to realize the positioning of the storage component 2 on the support component 1, that is, to make the storage component 2 remain at the current height after the height adjustment.

[0038] The positioning assembly 3 includes a top rod 31 corresponding to the positioning rod 111. In this embodiment, based on the vertically arranged positioning rod 111, the top rod 31 can be arranged horizontally. The first end of the top rod 31 corresponds to the locking portion 1111 of the positioning rod 111. The first end of the top cover can be inserted into or withdrawn from the locking portion 1111 of the positioning rod 111 under external control, so as to achieve the position locking and unlocking of the storage assembly 2. When in use, the user can first operate the top rod 31 to make its first end withdraw from the corresponding locking portion 1111, and then adjust the height of the storage assembly 2 up and down along the positioning rod 111. Finally, when it is adjusted to the corresponding height, the top rod 31 is re-operated until its first end is stuck in the corresponding locking portion 1111, thereby locking the position of the storage assembly 2. In addition, a plurality of locking portions 1111 are densely distributed on the positioning rod 111, that is, two adjacent locking portions 1111 are close to each other, so as to maximize the flexibility of adjusting the storage assembly 2 at any height.

[0039] The storage rack of the present invention utilizes a storage component that is slidably fitted on a support rod, and can flexibly adjust the height of the storage component. In addition, the positioning component on the storage component is further combined with the locking portion design of the positioning rod in the support rod to maximize the flexibility of adjusting the storage component at any height.

[0040] Furthermore, the plurality of support rods 11 include two positioning rods 111 , and the two positioning rods 111 are respectively matched with two opposite sides of the storage component 2 , and the two sides of the storage component 2 are respectively provided with positioning components 3 .

[0041] Specifically, in theory, one positioning rod 111 and one positioning assembly 3 can achieve the height adjustment requirement of the storage assembly 2. However, considering that the storage assembly 2 often has an area of ​​a certain size, only one positioning rod 111 and one positioning assembly 3 cannot ensure the balance of force (support force) of the entire storage assembly 2. Figure 1 As shown, positioning rods 111 are respectively provided on both sides of the storage assembly 2 and cooperate with corresponding positioning assemblies 3 to ensure that the storage assembly 2 is subjected to balanced force.

[0042] Furthermore, the storage assembly 2 includes a storage box 22 , and an extension portion 221 for the support rod 11 to pass through is extended from a side surface of the storage box 22 , and the positioning assembly 3 is installed on the outer side surface of the storage box 22 .

[0043] Specifically, Figures 1 to 4 As shown, the overall structure of the storage assembly 2 is a box-shaped structure, and the main body includes a storage box 22. The support rods 11 are respectively matched with the outside of the storage box 22 (including the left and right sides or also the back side), and the upper and lower edges of the side of the storage box 22 are respectively extended with extension parts 221, and the extension parts 221 are respectively provided with through holes corresponding to each support rod 11 for the assembly of the support rod 11.

[0044] In addition, the support rod 11 closest to the front side of the storage box 22 (i.e., the front side facing the user operation position) among the multiple support rods 11 is configured as a positioning rod 111, and the locking portion 1111 of the positioning rod 111 also faces the front side of the storage box 22. The positioning assembly 3 is fixed to the outer side (left and right sides) of the storage box 22, the first end of the push rod 31 faces the rear side of the storage box 22, i.e., corresponds to the locking portion 1111 of the positioning rod 111, and the second end of the push rod 31 faces the front side of the storage box 22.

[0045] Furthermore, a guide member 21 is provided on the storage assembly 2 , a guide hole 211 is configured on the guide member 21 , and a middle portion of the push rod 31 passes through the guide hole 211 .

[0046] Specifically, Figures 2 to 5As shown, the storage assembly 2 is provided with a guide member 21 for guiding the movement of the push rod 31. The guide member 21 is used to maintain the stability of the movement of the push rod 31 when it is inserted into or withdrawn from the locking portion 1111 of the positioning rod 111, mainly the stability of the movement direction, thereby ensuring that the push rod 31 can accurately cooperate with the corresponding locking portion 1111.

[0047] Example 2

[0048] An embodiment of the present invention provides a storage rack, which includes a support assembly 1, a storage assembly 2 and a positioning assembly 3. The support assembly 1 includes a plurality of support rods 11 parallel to each other, the plurality of support rods 11 include at least one positioning rod 111, and the positioning rod 111 is configured with a plurality of locking portions 1111 distributed along the length direction of the positioning rod 111; the storage assembly 2 is arranged on the support assembly 1, and the edge of the storage assembly 2 is slidably matched with the plurality of support rods 11; the positioning assembly 3 is arranged on the storage assembly 2 and corresponds to the positioning rod 111, and the positioning assembly 3 includes a top rod 31, and the top rod 31 is configured such that its first end can be inserted into or disengaged from the corresponding locking portion 1111 to lock or unlock the position of the storage assembly 2 on the support assembly 1.

[0049] Specifically, the overall structure of the rack is as follows: Figure 1 As shown, the main structure includes a support component 1 and a storage component 2 arranged on the support component 1. Among them, the storage component 2 is used to directly place items. According to needs, the storage component 2 can be a box body, a flat plate and other structures. The support component 1 is composed of a plurality of support rods 11. The height of the storage component 2 can be adjusted according to needs. The support rods 11 are vertically arranged, and the storage component 2 can slide along the support rods 11 to adjust the height. At the same time, the plurality of support rods 11 include at least one positioning rod 111 provided with a locking portion 1111 structure. The locking portion 1111 on the positioning rod 111 is used to cooperate with the positioning component 3 on the storage component 2 to realize the positioning of the storage component 2 on the support component 1, that is, to make the storage component 2 remain at the current height after the height adjustment.

[0050] The positioning assembly 3 includes a top rod 31 corresponding to the positioning rod 111. In this embodiment, based on the vertically arranged positioning rod 111, the top rod 31 can be arranged horizontally. The first end of the top rod 31 corresponds to the locking portion 1111 of the positioning rod 111. The first end of the top cover can be inserted into or withdrawn from the locking portion 1111 of the positioning rod 111 under external control, so as to achieve the position locking and unlocking of the storage assembly 2. When in use, the user can first operate the top rod 31 to make its first end withdraw from the corresponding locking portion 1111, and then adjust the height of the storage assembly 2 up and down along the positioning rod 111. Finally, when it is adjusted to the corresponding height, the top rod 31 is re-operated until its first end is stuck in the corresponding locking portion 1111, thereby locking the position of the storage assembly 2. In addition, a plurality of locking portions 1111 are densely distributed on the positioning rod 111, that is, two adjacent locking portions 1111 are close to each other, so as to maximize the flexibility of adjusting the storage assembly 2 at any height.

[0051] The storage rack of the present invention utilizes a storage component that is slidably fitted on a support rod, and can flexibly adjust the height of the storage component. In addition, the positioning component on the storage component is further combined with the locking portion design of the positioning rod in the support rod to maximize the flexibility of adjusting the storage component at any height.

[0052] Furthermore, the plurality of support rods 11 include two positioning rods 111 , and the two positioning rods 111 are respectively matched with two opposite sides of the storage component 2 , and the two sides of the storage component 2 are respectively provided with positioning components 3 .

[0053] Specifically, in theory, one positioning rod 111 and one positioning assembly 3 can achieve the height adjustment requirement of the storage assembly 2. However, considering that the storage assembly 2 often has an area of ​​a certain size, only one positioning rod 111 and one positioning assembly 3 cannot ensure the balance of force (support force) of the entire storage assembly 2. Figure 1 As shown, positioning rods 111 are respectively provided on both sides of the storage assembly 2 and cooperate with corresponding positioning assemblies 3 to ensure that the storage assembly 2 is subjected to balanced force.

[0054] Furthermore, the storage assembly 2 includes a storage box 22 , and an extension portion 221 for the support rod 11 to pass through is extended from a side surface of the storage box 22 , and the positioning assembly 3 is installed on the outer side surface of the storage box 22 .

[0055] Specifically, Figures 1 to 4 As shown, the overall structure of the storage assembly 2 is a box-shaped structure, and the main body includes a storage box 22. The support rods 11 are respectively matched with the outside of the storage box 22 (including the left and right sides or also the back side), and the upper and lower edges of the side of the storage box 22 are respectively extended with extension parts 221, and the extension parts 221 are respectively provided with through holes corresponding to each support rod 11 for the assembly of the support rod 11.

[0056] In addition, the support rod 11 closest to the front side of the storage box 22 (i.e., the front side facing the user operation position) among the multiple support rods 11 is configured as a positioning rod 111, and the locking portion 1111 of the positioning rod 111 also faces the front side of the storage box 22. The positioning assembly 3 is fixed to the outer side (left and right sides) of the storage box 22, the first end of the push rod 31 faces the rear side of the storage box 22, i.e., corresponds to the locking portion 1111 of the positioning rod 111, and the second end of the push rod 31 faces the front side of the storage box 22.

[0057] Furthermore, a guide member 21 is provided on the storage assembly 2 , a guide hole 211 is configured on the guide member 21 , and a middle portion of the push rod 31 passes through the guide hole 211 .

[0058] Specifically, Figures 2 to 5 As shown, the storage assembly 2 is provided with a guide member 21 for guiding the movement of the push rod 31. The guide member 21 is used to maintain the stability of the movement of the push rod 31 when it is inserted into or withdrawn from the locking portion 1111 of the positioning rod 111, mainly the stability of the movement direction, thereby ensuring that the push rod 31 can accurately cooperate with the corresponding locking portion 1111.

[0059] Furthermore, the locking portion 1111 is configured as a slot body opened in the positioning rod 111 , and the slot walls on the same side of the plurality of slot bodies in the length direction of the positioning rod 111 are configured as an inclined surface 4 for expanding the slot opening of the slot body.

[0060] Specifically, Figures 1 to 3 As shown, the locking part is integrally constructed as a slot body structure, and one side wall of the slot body is constructed as an inclined surface, and the inclined direction of the inclined surface is the direction in which the slot opening of the slot body is enlarged. Figure 3 In this embodiment, the inclined surface of the groove body is arranged on the top groove wall of the groove body, and all the inclined surfaces of the groove body are arranged on the top groove wall of the groove body. The purpose of this design is that the inclined surface can automatically squeeze the first end of the push rod out of the groove body when the storage assembly is lifted, thereby realizing automatic unlocking of the push rod, that is, it is used to unlock the push rod without additional control when the storage assembly is raised.

[0061] On the other hand, in this embodiment, the bottom groove wall of the groove body needs to stably support the top rod 31, so it cannot be set as an inclined surface 4. In this embodiment, the bottom groove wall of the groove body is set as a plane perpendicular to the axial direction of the positioning rod 111, and the contour of the bottom of the first end of the top rod 31 is also perpendicular to the axial direction of the positioning rod 111. In addition, in this embodiment, in order to improve the smoothness of the mutual extrusion between the inclined surface 4 of the groove wall at the top of the groove body and the top rod 31, for the top rod 31 itself, the top side of the first end of the top rod 31 is also set as an inclined surface 4 structure, such as Figure 3 shown.

[0062] Furthermore, the positioning assembly 3 also includes an elastic member 33 cooperating with the push rod 31 , and the elastic member 33 is configured to be driven to deform in a direction of increasing deformation when the push rod 31 is disengaged from the corresponding locking portion 1111 .

[0063] The elastic member 33 is matched with the second end of the push rod 31 , and one end of the elastic member 33 abuts against the second end of the push rod 31 , and the other end abuts against the inner side of the side plate of the storage assembly 2 .

[0064] Specifically, Figure 4 and Figure 5 As shown, the push rod 31 is equipped with an elastic member 33 to automatically realize rebound and utilize elastic preload to improve the stability of the push rod 31 when it is inserted into the locking portion 1111. In this embodiment, the elastic member 33 can be a spring, which is partially sleeved on the second end of the push rod 31, and the other end of the spring abuts against the inner side of the side plate (the front side plate in this embodiment) of the storage assembly 2.

[0065] Example 3

[0066] An embodiment of the present invention provides a storage rack, which includes a support assembly 1, a storage assembly 2 and a positioning assembly 3.

[0068] The positioning assembly 3 includes a top rod 31 corresponding to the positioning rod 111. In this embodiment, based on the vertically arranged positioning rod 111, the top rod 31 can be arranged horizontally. The first end of the top rod 31 corresponds to the locking portion 1111 of the positioning rod 111. The first end of the top cover can be inserted into or withdrawn from the locking portion 1111 of the positioning rod 111 under external control, so as to achieve the position locking and unlocking of the storage assembly 2. When in use, the user can first operate the top rod 31 to make its first end withdraw from the corresponding locking portion 1111, and then adjust the height of the storage assembly 2 up and down along the positioning rod 111. Finally, when it is adjusted to the corresponding height, the top rod 31 is re-operated until its first end is stuck in the corresponding locking portion 1111, thereby locking the position of the storage assembly 2. In addition, a plurality of locking portions 1111 are densely distributed on the positioning rod 111, that is, two adjacent locking portions 1111 are close to each other, so as to maximize the flexibility of adjusting the storage assembly 2 at any height.

[0069] The storage rack of the present invention utilizes a storage component that is slidably fitted on a support rod, and can flexibly adjust the height of the storage component. In addition, the positioning component on the storage component is further combined with the locking portion design of the positioning rod in the support rod to maximize the flexibility of adjusting the storage component at any height.

[0070] Furthermore, the plurality of support rods 11 include two positioning rods 111 , and the two positioning rods 111 are respectively matched with two opposite sides of the storage component 2 , and the two sides of the storage component 2 are respectively provided with positioning components 3 .

[0071] Specifically, in theory, one positioning rod 111 and one positioning assembly 3 can achieve the height adjustment requirement of the storage assembly 2. However, considering that the storage assembly 2 often has an area of ​​a certain size, only one positioning rod 111 and one positioning assembly 3 cannot ensure the balance of force (support force) of the entire storage assembly 2. Figure 1 As shown, positioning rods 111 are respectively provided on both sides of the storage assembly 2 and cooperate with corresponding positioning assemblies 3 to ensure that the storage assembly 2 is subjected to balanced force.

[0072] Furthermore, the storage assembly 2 includes a storage box 22 , and an extension portion 221 for the support rod 11 to pass through is extended from a side surface of the storage box 22 , and the positioning assembly 3 is installed on the outer side surface of the storage box 22 .

[0073] Specifically, Figures 1 to 4 As shown, the overall structure of the storage assembly 2 is a box-shaped structure, and the main body includes a storage box 22. The support rods 11 are respectively matched with the outside of the storage box 22 (including the left and right sides or also the back side), and the upper and lower edges of the side of the storage box 22 are respectively extended with extension parts 221, and the extension parts 221 are respectively provided with through holes corresponding to each support rod 11 for the assembly of the support rod 11.

[0074] In addition, the support rod 11 closest to the front side of the storage box 22 (i.e., the front side facing the user operation position) among the multiple support rods 11 is configured as a positioning rod 111, and the locking portion 1111 of the positioning rod 111 also faces the front side of the storage box 22. The positioning assembly 3 is fixed to the outer side (left and right sides) of the storage box 22, the first end of the push rod 31 faces the rear side of the storage box 22, i.e., corresponds to the locking portion 1111 of the positioning rod 111, and the second end of the push rod 31 faces the front side of the storage box 22.

[0075] Furthermore, a guide member 21 is provided on the storage assembly 2 , a guide hole 211 is configured on the guide member 21 , and a middle portion of the push rod 31 passes through the guide hole 211 .

[0076] Specifically, Figures 2 to 5 As shown, the storage assembly 2 is provided with a guide member 21 for guiding the movement of the push rod 31. The guide member 21 is used to maintain the stability of the movement of the push rod 31 when it is inserted into or withdrawn from the locking portion 1111 of the positioning rod 111, mainly the stability of the movement direction, thereby ensuring that the push rod 31 can accurately cooperate with the corresponding locking portion 1111.

[0077] Furthermore, the locking portion 1111 is configured as a slot body opened in the positioning rod 111 , and the slot walls on the same side of the plurality of slot bodies in the length direction of the positioning rod 111 are configured as an inclined surface 4 for expanding the slot opening of the slot body.

The purpose of this design is that the inclined surface can automatically squeeze the first end of the push rod out of the groove body when the storage assembly is lifted, thereby realizing automatic unlocking of the push rod, that is, it is used to unlock the push rod without additional control when the storage assembly is raised.

[0079] On the other hand, in this embodiment, the bottom groove wall of the groove body needs to stably support the top rod 31, so it cannot be set as an inclined surface 4. In this embodiment, the bottom groove wall of the groove body is set as a plane perpendicular to the axial direction of the positioning rod 111, and the contour of the bottom of the first end of the top rod 31 is also perpendicular to the axial direction of the positioning rod 111. In addition, in this embodiment, in order to improve the smoothness of the mutual extrusion between the inclined surface 4 of the groove wall at the top of the groove body and the top rod 31, for the top rod 31 itself, the top side of the first end of the top rod 31 is also set as an inclined surface 4 structure, such as Figure 3 shown.

[0080] Furthermore, the positioning assembly 3 also includes an elastic member 33 cooperating with the push rod 31 , and the elastic member 33 is configured to be driven to deform in a direction of increasing deformation when the push rod 31 is disengaged from the corresponding locking portion 1111 .

[0081] The elastic member 33 is matched with the second end of the push rod 31 , and one end of the elastic member 33 abuts against the second end of the push rod 31 , and the other end abuts against the inner side of the side plate of the storage assembly 2 .

[0082] Specifically, Figure 4 and Figure 5 As shown, the push rod 31 is equipped with an elastic member 33 to automatically realize rebound and utilize elastic preload to improve the stability of the push rod 31 when it is inserted into the locking portion 1111. In this embodiment, the elastic member 33 can be a spring, which is partially sleeved on the second end of the push rod 31, and the other end of the spring abuts against the inner side of the side plate (the front side plate in this embodiment) of the storage assembly 2.

[0083] Furthermore, the positioning assembly 3 also includes a transmission unit 32, which includes a lever 321 and a pressing piece 322. The middle part of the lever 321 is hinged to the inner side of the storage assembly 2, and the two ends of the lever 321 are respectively hinged to the second end of the top rod 31 and the second end of the pressing piece 322. The first end of the pressing piece 322 passes through the storage assembly 2 to the outside of the storage assembly 2.

[0084] Specifically, Figures 1 to 5 As shown, the positioning assembly 3 drives the push rod 31 through the transmission unit 32, and the transmission unit 32 also realizes the interaction between the positioning assembly 3 and the user. The transmission unit 32 is constructed as a lever structure, which includes a lever 321 and a pressing member 322. The middle part of the lever 321 is hinged to the inner side of the storage assembly 2 (in this embodiment, it is hinged to the inner side of the front side plate of the storage box 22), and the two ends of the lever 321 are respectively hinged to the second end of the push rod 31 and the second end of the pressing member 322, wherein there is a certain distance between the hinge point between the lever 321 and the second end of the push rod 31 and the end surface of the second end of the push rod 31, which is used to set a spring, such as Figure 8 The pressing member 322 is integrally disposed in the storage assembly 2 (in this embodiment, it is disposed in the side plate on the front side of the storage box 22), and the first end of the pressing member 322 is located outside the storage assembly 2, and can be pressed by the user to control the top rod 31. Figure 6 As shown in the figure, the first end of the push rod 31 is stuck in the locking portion 1111 under the action of the pre-tightening force of the elastic member 33, and the first end of the pressing member 322 is also extended to the maximum extent outside the storage assembly 2 under the action of the pre-tightening force of the elastic member 33; when the user presses the first end of the pressing member 322, the push rod 31 is driven to withdraw from the locking portion 1111 and compress the elastic member 33 through the action of the lever 321, as shown in the figure. Figure 7 shown.

[0085] Furthermore, the lever 321 is hinged to the push rod 31 and the pressing piece 322 through a hinge structure 34, and the hinge structure 34 includes a long hole 341 and a pin 342 fitted in the long hole 341; wherein the long hole 341 is opened at the end of the lever 321, and the pin 342 is arranged at the ends of the push rod 31 and the pressing piece 322; or the pin 342 is arranged at the end of the lever 321, and the long hole 341 is respectively opened at the ends of the push rod 31 and the pressing piece 322.

[0086] Specifically, Figure 5 As shown, the lever 321 rotates when the user presses the pressing piece 322, but the pressing piece 322 itself and the push rod 31 perform linear translation. Therefore, the intersection of the lever 321, the push rod 31 and the pressing piece 322 needs further design to compensate for the relative displacement caused by the different movement conditions of the corresponding components. That is, the hinge structure 34 formed by the long hole 341 and the pin 342 allows the pin 342 to move relatively in the long hole 341 to compensate for the mismatch between the displacement caused by the linear movement of the push rod 31 and the pressing piece 322 and the circular movement of the lever 321.
