[0035] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer, the following will be further described in detail in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

In addition, it should be noted that the specification describes many features. Although certain features can be combined together to show possible system designs, these features can also be used in other combinations that are not explicitly described. Therefore, unless otherwise stated, the combinations described are not intended to be limiting.

[0036] The principles and structures of the utility model will be described in detail in combination with the drawings and embodiments.

[0037] In some embodiments, as shown in the drawings, Figures 1-2 The utility model provides a connecting structure, which comprises a stand column 10 and an article 20 sleeved on the stand column 10 through a sleeve 201; each stand column 10 comprises a plurality of module segments 101, any two adjacent module segments 101 are sleeved, and at least one pair of positioning holes 102 is arranged through the side wall at the sleeving position;

[0038] Each sleeving position is surrounded by a clamping piece combination 30 composed of a first clamping piece 301 and a second clamping piece 302, and the inner side of the first clamping piece 301 and the second clamping piece 302 is provided with a protrusion 303 matched with the positioning hole 102;

[0039] The sleeve 201 of the article 20 is matched and sleeved on the clamping piece combination 30.

[0040] It can be understood that the stand column 10 in the embodiment is exemplified in a cylindrical shape, and of course, the stand column 10 can also be in a prismatic shape or other suitable shapes, which are not limited herein. Each positioning hole 102 is arranged through the side wall of the two module segments 101 at the sleeving position; and the inner side of the first clamping piece 301 and the second clamping piece 302 is provided with an arc-shaped contact surface matched with the outer contour of the stand column 10.

[0041] Wherein, the embodiment first matches and connects any two adjacent module segments 101, and then matches and connects the positioning holes 102 of the two module segments 101, and then matches and embeds the protrusions 303 of the first and second clamping pieces 301 and 302 into the corresponding positioning holes 102, so as to form the clamping piece combination 30 at the connected part of the stand 10, and then matches and connects the sleeve 201 of the storage object 20 on the clamping piece combination 30, and the sleeve 201 is tightly pressed against the clamping piece combination 30 due to the combined gravity of the storage object 20 and the placed articles, so as to tightly hold the clamping piece combination 30 on the connected part of the stand 10, and then stably place the storage object 20 on the stand 10 (as shown in Figure 4 and Figure 6 The above steps are sequentially completed for multiple times, so as to form a storage device with multiple layers of storage objects 20.

[0042] When it is necessary to disassemble the storage object 20 in any position, the storage object 20 in the position is first lifted upwards to be separated from the corresponding clamping piece combination 30, and then the protrusions 303 of the first and second clamping pieces 301 and 302 are separated from the corresponding positioning holes 102, and then the two module segments 101 at the corresponding connected part are separated and disassembled, so that the storage object 20 in the layer is disassembled, so that the connecting structure provided by the embodiment can be arbitrarily disassembled, and the disassembly steps are simpler, and can be flexibly adapted to different space environments and storage requirements.

[0043] Therefore, the protrusions 303 on the inner side of the clamping piece combination 30 pass through the positioning holes 102 at the connected part of the stand 10 at the same time, so as to surround the connected part of the stand 10, and then the sleeve 201 of the storage object 20 is matched and connected on the clamping piece combination 30, so as to tightly hold the clamping piece combination 30 on the stand 10, which not only facilitates installation, but also improves the structural stability of the connecting structure, and significantly improves the practical value of the connecting structure.

[0044] Wherein, the shape of the protrusions 303 is preferably a circular truncated cone, and of course, the shape of the protrusions 303 can also be selected as a circular column, a sphere, an oval, a prism or other suitable shapes for insertion according to actual needs, which is not limited herein.

[0045] In some embodiments, the size of the protrusions 303 gradually decreases along the protruding direction. It can be understood that when the protrusions 303 are in the shape of a circular truncated cone, the diameter of one end of the protrusions 303 connected to the clamping piece is the largest, so that the first and second clamping pieces 301 and 302 can be better fixed at the connected part, so as to avoid that the protrusions 303 of the first and second clamping pieces 301 and 302 are easily separated from the corresponding positioning holes 102.

[0046] In some embodiments, in order to further improve the structural stability when the clamping piece combination 30 surrounds the connected part of the stand 10, the first and second clamping pieces 301 and 302 are provided with a plurality of protrusions 303, and the protrusions 303 are arranged in a staggered manner. Figure 1As shown, both ends of the connection of the first clamping piece 301 and the second clamping piece 302 are respectively provided with at least one clamping block 304 and / or at least one clamping slot 305.

[0047] The clamping block 304 is matched and clamped with the corresponding clamping slot 305.

[0048] It can be understood that when the first clamping piece 301 and the second clamping piece 302 enclose the column 10, both ends of the first clamping piece 301 and the second clamping piece 302 distributed circumferentially along the column 10 are respectively provided with at least one clamping block 304 and / or at least one clamping slot 305.

[0049] And the clamping block 304 and the clamping slot 305 proposed in the embodiment are all illustrated by one. Of course, the number of the clamping block 304 and the clamping slot 305 can also be set to two or more than two according to the actual situation, which is not limited here.

[0050] In this way, when the protruding block 303 of the first clamping piece 301 and the second clamping piece 302 is matched and embedded into the corresponding positioning hole 102, the clamping block 304 of the first clamping piece 301 can also be matched and clamped to the clamping slot 305 of the second clamping piece 302, and the clamping block 304 of the second clamping piece 302 is matched and clamped to the clamping slot 305 of the first clamping piece 301 (as Figure 2 shown), thereby forming a clamping piece combination 30 around the sleeving part of the column 10.

[0051] Of course, in other embodiments (not shown in the figure), in order to further improve the structural stability of the clamping piece combination 30 around the sleeving part of the column 10, both ends of the connection of the first clamping piece 301 are vertically provided with two clamping blocks 304;

[0052] Both ends of the connection of the second clamping piece 302 are vertically provided with clamping slots 305 matched with the clamping blocks 304.

[0053] As Figure 5 shown, and when the protruding block 303 of each first clamping piece 301 and second clamping piece 302 is provided with two or more than two, correspondingly, the positioning hole 102 of the sleeving part of the column 10 is also provided with two or more than two; and at this time, the protruding block 303 on the first clamping piece 301 and the second clamping piece 302 is arranged side by side or vertically or obliquely, which is not limited here.

[0054] In some embodiments, in order to ensure that the sleeve 201 can better extrude the clamping piece combination 30 due to the weight of the placed object 20 and the placed object, thereby improving the stability of the connection structure and the storage device, the outer diameter size of any of the clamping piece combinations 30 proposed in the embodiment is sequentially increased along the axial direction from the top end to the bottom end, the inner diameter size of the sleeve 201 is sequentially increased along the axial direction from the top end to the bottom end; the inner side of the sleeve 201 and the outer side of the clamping piece combination 30 form a progressive matching structure.

[0055] It can be understood that the sleeve 201 and the clamping piece combination 30 are preferably in the shape of a circular truncated cone. Of course, the sleeve 201 and the clamping piece combination 30 can also be in the shape of a prismatic truncated cone or other suitable shapes according to actual conditions, which are not limited herein.

[0056] In this way, when the sleeve 201 is matched and sleeved on the clamping piece combination 30, because the inner diameter of the sleeve 201 increases from the top end to the bottom end in turn, when the sleeve 201 moves downward due to the gravity of the placed object 20 and the placed object, the extrusion force, the contact area and the anti-slip resistance between the sleeve 201 and the clamping piece combination 30 will be multiplied due to the synergistic effect of the interference amount accumulation effect and the geometric constraint, so that the connection is more stable.

[0057] The interference amount accumulation effect is specifically as follows:

[0058] 1. The interference amount between the sleeve 201 and the clamping piece combination 30 increases with the depth. Assuming that the taper angle of the sleeve 201 and the clamping piece combination 30 is θ (as shown in FIG. 1, the taper angle θ is the angle between the generatrix of the sleeve 201 or the generatrix of the clamping piece combination 30 and the axis thereof), and the sleeving depth is h, then the interference amount δ and the depth are in linear relationship: Figure 2 δ = h x tan θ;

[0059]

[0060] When sleeved to the bottom, h is the largest, the interference amount δ reaches the peak, and the contact surface (equivalent to the inner side surface of the sleeve 201 and / or the outer side surface of the clamping piece combination 30) is subjected to the synchronous increase of the normal pressure P:

[0061]

[0062] Wherein, E is the elastic modulus, v is the Poisson's ratio, and D is the average diameter of the contact surface.

[0063] 2. The friction force between the sleeve 201 and the clamping piece combination 30 also increases exponentially.

[0064] The increase of the contact pressure P leads to the significant increase of the friction force F f :

[0065] F f = μ x P x A;

[0066] A = π x D x L;

[0067] Wherein, μ is the friction coefficient, A is the contact area, and L is the contact length.

[0068] Therefore, the friction force is proportional to the depth h, and the anti-slip ability is the strongest at the bottom region of the clamping piece combination 30.

[0069] ​And the geometric constraint is strengthened specifically as follows:

[0070] 1. The contact surface angle of the sleeve 201 and the clamping piece combination 30 is self-locked.

[0071] The taper angle θ needs to meet the self-locking condition:

[0072] θ≤arctanμ;

[0073] When the sleeve 201 is sleeved to the bottom, the actual contact angle of the contact surface tends to 0°, forming an approximate rigid constraint, which requires a large external force to break the balance.

[0074] 2. The eccentric load resistance is improved.

[0075] The contact area ratio of the bottom area of the sleeve 201 and the clamping piece combination 30 is larger, and the cross-sectional moment of inertia I increases by the fourth power with the increase of the diameter:

[0076]

[0077] Wherein, Do is the diameter of the sleeve 201, and Di is the diameter of the clamping piece combination 30.

[0078] The larger cross-sectional moment of inertia I significantly improves the bending stiffness and suppresses the axial deviation caused by eccentric load.

[0079] In some embodiments, each pair of positioning holes 102 is on the same cross section perpendicular to the radial direction of the column 10, and each pair of positioning holes 102 is distributed symmetrically along the radial direction of the column 10.

[0080] In this way, the structural stability of the clamping piece combination 30 when surrounding the sleeving 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 not be on the same cross section.

[0081] In some embodiments, in order to ensure that the column 10 can be detachably connected, as shown in Figure 1 and Figure 6 The lower end of the module segment 101 located inside the sleeving part is provided with a sleeving part 103, and the sleeving part 103 can be matched and inserted into the upper end of the module segment 101 located outside the sleeving part.

[0082] It can be understood that the diameter of the sleeving part 103 is smaller than the diameter of the top of the module segment 101, and the sleeving part 103 is inserted into the upper end of the module segment 101.

[0083] Wherein, in order to ensure the durability of the clamping piece combination, the material of the clamping piece combination 30 is any one of carbon steel, stainless steel and aluminum alloy. Of course, the material of the clamping piece combination 30 can also be other metals and materials with high durability, which is not limited here.

[0084] To ensure the durability of the clamp assembly, the column 10 is made of any one of carbon steel, stainless steel, and aluminum alloy. Of course, the column 10 can also be made of other metals and highly durable materials, which are not limited here.

[0085] In some embodiments, the present invention also provides a storage device, the storage device including the connection structure described above.

[0086] It is understandable that the positioning hole 102 at the sleeve of the column 10 of the storage device corresponds to the protrusion 303 on the inner side of the clip assembly 30, so as to surround the sleeve of the column 10. Then the sleeve 201 of the object 20 is fitted onto the clip assembly 30, so that the clip assembly 30 tightly hugs the column 10. This not only makes installation convenient, but also improves the structural stability of the storage device and significantly enhances the practical value of the storage device.

[0087] Furthermore, when it is necessary to disassemble the storage device at any position of the storage component 20, the storage component 20 at that position can be lifted upwards to disengage it from the corresponding clip assembly 30. Then, the protrusions 303 of the first clip 301 and the second clip 302 can be disengaged from the corresponding positioning holes 102. Then, the two module segments 101 at the corresponding socket can be separated and disassembled. The storage component 20 of that layer can then be removed. Thus, the storage device proposed in this embodiment can not only be disassembled at will, but the disassembly steps are also simpler, and it can flexibly adapt to different spatial environments and storage needs.

[0088] The storage device includes any one of a shelf, a wall-mounted shelf, or a storage cart.

[0089] Specifically, such as Figure 3 As shown, when the storage device is preferably a shelf, the shelf 20 is preferably a square shelf, and each of the four corners of the shelf is provided with a sleeve 201. Then, all the sleeves 201 of the shelf are respectively fitted onto the clip assembly 30 at the joint of different uprights 10, thereby forming a shelf.

[0090] Of course, the shape of the shelves can also be selected as a triangle or other suitable shape depending on the actual situation, and there are no restrictions here.

[0091] When the shelf is triangular in shape, a sleeve 201 is provided at each of the triangular parts of the shelf. Each sleeve 201 is then fitted onto the clip assembly 30 at the joint of different uprights 10, thereby forming a shelf.

[0092] Specifically, when the storage device is preferably a storage trolley, at this time the storage article 20 is preferably a square storage frame, and the middle of both sides of the storage frame is provided with a sleeve 201, then all the sleeves 201 of the storage frame are respectively sleeved on the clamping piece combination 30 at the sleeving position of different stand columns 10, and the bottom end of each stand column 10 is provided with a roller, thereby forming a storage trolley.

[0093] Of course, the shape of the storage frame can also be selected as an ellipse or other suitable shape according to actual conditions, which is not limited here.

[0094] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
