[0019] In order to more clearly clarify the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention, the present invention will be described in more detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only for explaining the present invention and do not limit the scope of the present invention. Thus, one feature described in this specification is for explaining one feature in one embodiment of the present invention, and does not imply that all embodiments of the present invention must have such a feature. Furthermore, although many features are described in this specification, although some features may be described in combination to show possible system designs, note that these features are also applicable to other combinations not explicitly described. Therefore, unless otherwise specified, the described combinations are not intended to be limiting.

[0020] Hereinafter, the principle and structure of the present invention will be described in detail in combination with the drawings and embodiments.

[0021] In some embodiments, as shown in FIGS. 1-2, the present invention proposes a connection structure, which includes a support column 10 and a storage member 20 fitted on the support column 10 by a sleeve 201. Each of the support columns 10 includes a plurality of module segments 101. Any two adjacent module segments 101 are fitted with each other, and at least a pair of positioning holes 102 penetrate through the side wall of the fitting part. Each of the fitting parts is correspondingly surrounded by a clamp piece combination 30 composed of a first clamp piece 301 and a second clamp piece 302. Protruding blocks 303 fitted with the positioning holes 102 are provided on the inner surfaces of both the first clamp piece 301 and the second clamp piece 302. The sleeve 201 of the storage member 20 is fitted according to the clamp piece combination 30.

[0022] As can be understood, the support column 10 in this embodiment is described by taking a cylindrical shape as an example. Of course, the support column 10 may also be a prismatic shape or other suitable shapes, and is not limited here. In addition, each positioning hole 102 penetrates the side walls of the two module segments 101 in the fitting part, and an arch-shaped contact surface adapted to the outer contour of the support column 10 is provided inside the first clamp piece 301 and the second clamp piece 302.

[0023] Here, in this embodiment, any two adjacent module segments 101 are fitted with each other, the positioning holes 102 of the two module segments 101 fitted with each other are overlapped correspondingly, then the protruding blocks 303 of the first clamp piece 301 and the second clamp piece 302 are fitted into the corresponding positioning holes 102, thereby surrounding the fitting part of the support column 10 to form a clamp piece combination 30, and the sleeve 201 of the storage member 20 is fitted according to the clamp piece combination 30. The sleeve 201 strongly presses the clamp piece combination 30 under the combined gravity of the storage member 20 and the articles stored therein. Further, the clamp piece combination 30 firmly holds the fitting part of the support column 10, and the storage member 20 is stably placed on the support column 10 (see FIGS. 4 and 6). Then, this is completed sequentially multiple times to constitute a storage device having multiple-stage storage members 20.

[0024] Also, if it is necessary to remove the storage member 20 at an arbitrary position, first lift the storage member 20 at this position and detach it from the corresponding clamp piece combination 30. Next, detach the protruding blocks 303 of the first clamp piece 301 and the second clamp piece 302 from the corresponding positioning holes 102, separate and remove the two module segments 101 corresponding to the fitting part from each other, and the storage member 20 at this stage can be removed. Thus, the connection structure according to this embodiment is not only freely removable, but also the removal steps are simpler and can flexibly adapt to different space environments and storage requirements.

[0025] Therefore, in the present invention, the protruding block 303 on the inner surface of the clamp piece combination 30 simultaneously penetrates the positioning hole 102 of the fitting part of the support column 10 and surrounds the fitting part of the support column 10. Next, the sleeve 201 of the storage member 20 is fitted in accordance with the clamp piece combination 30, and the clamp piece combination 30 firmly holds the support column 10. In this way, not only is the installation easy, but also the structural stability of the connection structure is improved, and the practical value of the connection structure is significantly improved.

[0026] Here, the shape of the protruding block 303 according to this embodiment is preferably frustum-shaped. Of course, the shape of the protruding block 303 can also be selected from a cylindrical shape, a spherical shape, an elliptical shape, a prismatic shape, or other shapes suitable for fitting according to actual needs, and is not limited here.

[0027] In some embodiments, the dimensions of the protruding block 303 gradually decrease along its protruding direction.

[0028] As can be understood, when the protruding block 303 is frustum-shaped, the diameter of the end of the protruding block 303 connected to the clamp piece is the largest, and the first clamp piece 301 and the second clamp piece 302 can be better fixed by the fitting part. Thus, the protruding blocks 303 of the first clamp piece 301 and the second clamp piece 302 are prevented from easily detaching from the corresponding positioning holes 102.

[0029] In some embodiments, in order to further improve the structural stability of the clamp piece combination 30 surrounding the fitting portion of the support column 10, as shown in FIG. 1, at least one engaging block 304 and / or at least one engaging groove 305 are respectively provided at both ends of the connection portion between the first clamp piece 301 and the second clamp piece 302. The engaging block 304 is engaged with the corresponding engaging groove 305.

[0030] As can be understood, when the first clamp piece 301 and the second clamp piece 302 surround the support column 10, at least one engaging block 304 and / or at least one engaging groove 305 are respectively provided at both ends of the support column 10 distributed in the circumferential direction between the first clamp piece 301 and the second clamp piece 302.

[0031] And the engaging block 304 and the engaging groove 305 according to this embodiment are described as examples respectively. Of course, it is also possible to set the number of the engaging block 304 and the engaging groove 305 to two or more according to the actual situation, and it is not limited here.

[0032] In this way, when the protruding block 303 of the first clamp piece 301 and the second clamp piece 302 is fitted into the corresponding positioning hole 102 at the same time, the engaging block 304 of the first clamp piece 301 can be further engaged with the engaging groove 305 of the second clamp piece 302, and the engaging block 304 of the second clamp piece 302 is correspondingly engaged with the engaging groove 305 (see FIG. 2) of the first clamp piece 301, surrounding the fitting portion of the support column 10 to form the clamp piece combination 30.

[0033] Of course, in other embodiments (not shown), in order to further improve the structural stability when the clamp piece combination 30 surrounds the fitting portion of the support column 10, two engaging blocks 304 are vertically provided at both ends of the connection portion of the first clamp piece 301. Engaging grooves 305 that are fitted with the engaging blocks 304 are vertically provided at both ends of the connection portion of the second clamp piece 302.

[0034] As shown in Fig. 5, when two or more protruding blocks 303 are provided on each of the first clamping pieces 301 and the second clamping pieces 302, correspondingly, two or more positioning holes 102 are also provided correspondingly at the fitting portions of the support columns 10. At this time, the protruding blocks 303 on the first clamping pieces 301 and the second clamping pieces 302 can all be arranged in parallel, vertically or inclined, and are not limited here.

[0035] In some embodiments, in order to improve the stability of the connection structure and the storage device by pressing the clamping piece combination 30 better with the gravity of the sleeve 201, the storage member 20 and the articles stored therein, the outer diameter dimensions of any of the clamping piece combinations 30 according to this embodiment increase sequentially from the top end to the bottom end along the axial direction, the inner diameter dimensions of the sleeve 201 increase sequentially from the top end to the bottom end along the axial direction, and the inner side surface of the sleeve 201 and the outer side surface of the clamping piece combination 30 form a progressive fitting structure.

[0036] As can be understood, the shapes of the sleeve 201 and the clamping piece combination 30 according to this embodiment are preferably both frustum-shaped. Of course, the shapes of the sleeve 201 and the clamping piece combination 30 can also be selected as frustum-shaped or other appropriate shapes according to the actual situation, and are not limited here.

[0037] In this way, when the sleeve 201 is fitted according to the clamping piece combination 30, since the inner diameter of the sleeve 201 increases sequentially from the top end to the bottom end, when the sleeve 201 moves downward under the gravity of the storage member 20 and the articles stored therein, due to the synergistic effect of the interference cumulative effect and the geometric constraint strengthening between the sleeve 201 and the clamping piece combination 30, the pressing force, the contact area and the anti-slip resistance between the two increase multiplicatively, so the connection is more stable.

[0038] The interference cumulative effect specifically is 1. The interference between the sleeve 201 and the clamp piece combination 30 increases with the depth. Assuming the taper angle between the sleeve 201 and the clamp piece combination 30 is θ (refer to Figure 2, where the taper angle θ is the angle between the generatrix of the sleeve 201 or the clamp piece combination 30 and its axis), and the embedding depth is h, the interference δ and the depth present a linear relationship. When embedded at the bottom, h reaches the maximum, the interference δ peaks, and the normal pressure P on the contact surface (corresponding to the inner surface of the sleeve 201 and / or the outer surface of the clamp piece combination 30) increases synchronously. Here, E is the modulus of elasticity, v is the Poisson's ratio, and D is the average diameter of the contact surface.

[0039] [Number] When embedded at the bottom, h is at its maximum, the interference δ reaches its peak, and the normal pressure P on the contact surface (corresponding to the inner surface of the sleeve 201 and / or the outer surface of the clamp piece combination 30) increases synchronously. Here, E is the modulus of elasticity, v is the Poisson's ratio, and D is the average diameter of the contact surface.

[0040] [Number] Here, E is the modulus of elasticity, v is the Poisson's ratio, and D is the average diameter of the contact surface. 2. The frictional force between the sleeve 201 and the clamp piece combination 30 also increases exponentially. As the contact pressure P increases, the frictional force F increases significantly. Here, μ is the coefficient of friction, A is the contact area, and L is the contact length. Therefore, the frictional force is proportional to the depth h, and the anti-slip ability of the area at the bottom of the clamp piece combination 30 is the strongest. As the contact pressure P increases, the frictional force F f increases significantly.

[0041] [Number] Here, μ is the coefficient of friction, A is the contact area, and L is the contact length. Therefore, the frictional force is proportional to the depth h, and the anti-slip ability of the area at the bottom of the clamp piece combination 30 is the strongest.

[0042] The geometric constraint strengthening specifically includes: 1. Self-locking due to the contact surface angle between the sleeve 201 and the clamp piece combination 30. The taper angle θ needs to meet the self-locking condition. The taper angle θ needs to meet the self-locking condition.

[0043] [Number] When the sleeve 201 is fitted at the bottom, the actual contact angle of the contact surface is nearly 0°, forming a restraint of approximate rigidity and requiring an extremely large external force to break the balance. 2. Improvement of the resistance to eccentric load. The ratio of the contact area between the sleeve 201 and the bottom region of the clamp piece combination 30 is larger, and the second moment of area I increases quadratically with the increase of the diameter.

[0044]

Number

[0045] In some embodiments, each pair of the positioning holes 102 are all located in the same cross-section perpendicular to the radial direction of the column 10 and are symmetrically distributed along the radial direction of the column 10.

[0046] In this way, the structural stability of the clamp piece combination 30 surrounding the fitting part of the column 10 can be ensured. Of course, if there are two or more pairs of positioning holes 102, different pairs of positioning holes 102 can be located in the same cross-section.

[0047] In some embodiments, in order to ensure the removable connection of the column 10, as shown in FIGS. 1 and 6, a fitting portion 103 is provided at the lower end of the module segment 101 inside the fitting part, and the fitting portion 103 can be inserted together with the upper end of the module segment 101 outside the fitting part.

[0048] As can be understood, the diameter of the fitting portion 103 is smaller than the diameter of the top of the module segment 101, and the fitting portions 103 are all inserted into the upper end of the module segment 101.

[0049] Here, in order to ensure the durability of the clamp piece combination, the material of the clamp piece combination 30 is any one of carbon steel, stainless steel, and aluminum alloy. Naturally, the material of the clamp piece combination 30 may also be other metals and materials with high durability, and is not limited here.

[0050] Here, in order to ensure the durability of the clamp piece combination, the material of the support column 10 is any one of carbon steel, stainless steel, and aluminum alloy. Naturally, the material of the support column 10 may also be other metals and materials with high durability, and is not limited here.

[0051] In some embodiments, the present invention further proposes a storage device provided with the connection structure described above.

[0052] As can be understood, the protruding block 303 on the inner surface of the clamp piece combination 30 is correspondingly inserted into the positioning hole 102 of the fitting part of the support column 10 of the storage device so as to surround the fitting part of the support column 10. Next, the sleeve 201 of the storage member 20 is fitted in accordance with the clamp piece combination 30, and the clamp piece combination 30 firmly holds the support column 10. In this way, not only is the installation easy, but also the structural stability of the storage device is improved, and the practical value of the storage device is significantly improved.

[0053] Also, if it is necessary to remove the storage member 20 at any position of the storage device, first lift the storage member 20 at this position and detach it from the corresponding clamp piece combination 30. Next, detach the protruding blocks 303 of the first clamp piece 301 and the second clamp piece 302 from the corresponding positioning holes 102, and separate and remove the two module segments 101 corresponding to the fitting part from each other, and the storage member 20 at this stage can be removed. Thus, the storage device according to this embodiment is not only freely removable, but also the removal steps are simpler, and it can flexibly adapt to different space environments and storage requirements.

[0054] Here, the storage device includes any one of a storage shelf, a wall-mounted rack, or a storage cart.

[0055] Specifically, as shown in FIG. 3, when the storage device is preferably a storage shelf, at this time, the storage member 20 is a square storage shelf board, and it is preferable that sleeves 201 are provided at all four corners of the storage shelf board. Next, all the sleeves 201 of the storage shelf board are respectively fitted into the clamp piece combinations 30 of the fitting parts of different columns 10, thereby forming a storage shelf.

[0056] Of course, the shape of the storage shelf board can also be selected as a triangle or other appropriate shape according to the actual situation, and is not limited here.

[0057] When the shape of the storage shelf board is a triangle, at this time, sleeves 201 are provided at all three corners of the storage shelf board. Next, each sleeve 201 is respectively fitted into the clamp piece combination 30 of the fitting part of a different column 10, thereby forming a storage shelf.

[0058] Specifically, when the storage device is preferably a storage cart, at this time, the storage member 20 is a square storage frame, and it is preferable that sleeves 201 are provided at the middle parts on both sides of the storage frame. Next, all the sleeves 201 of the storage frame are respectively fitted into the clamp piece combinations 30 of the fitting parts of different columns 10, and rollers are provided at the bottom ends of each column 10, thereby forming a storage cart.

[0059] Of course, the shape of the storage frame can also be selected as an ellipse or other appropriate shape according to the actual situation, and is not limited here.

[0060] Obviously, the embodiments described above are only some embodiments of the present invention, not all embodiments. Although the preferred embodiments of the present invention are shown in the drawings, they do not limit the scope of the present invention. The present invention can be realized in many different forms.
