Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a connection structure for connecting the uprights of a glass storage cabinet with a single-arm adjustable arm. Background Technology

[0002] As the name suggests, a glass cabinet is a cabinet made of glass. Glass cabinets are widely used in shopping malls or exhibition venues to display products. A glass cabinet is mainly used as a counter to store items.

[0003] Currently, the connection between the monoclamp and the column is generally achieved by bolts. Bolt connection requires the use of nuts. However, the column is made of profiles, and due to its structural principle, it cannot provide enough operating space for the operator. Therefore, using bolts and nuts to lock the components increases the difficulty of assembly. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the prior art by providing a connection structure that connects the glass storage cabinet column to the adjustable arm to solve the aforementioned problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This connection structure for connecting the uprights and monolithic arms of a glass storage cabinet includes an upright and several monolithic arms. Each monolithic arm has a first assembly end face, a first insertion cavity is provided on the first assembly end face, a movable monolithic arm connecting block is provided in the first insertion cavity, and a locking rod is provided on the monolithic arm connecting block to limit it to the upright. The upright has a second assembly end face that contacts the first assembly end face, a second insertion cavity is provided on the second assembly end face, and the second insertion cavity is provided on the upright with multiple locking holes that can limit the corresponding monolithic arm connecting blocks to the final assembly position of the upright. The locking rod and the locking holes are combined and locked by rotation.

[0006] Further improvements include a lower opening on the monotonic arm that allows the monotonic arm connecting block to enter the first insertion cavity, and a side opening that allows part of the monotonic arm connecting block to extend out of the first insertion cavity.

[0007] Further improvements include a stepped configuration for the first insertion cavity, with inwardly extending protrusions at the stepped corners formed by the narrow and wide sections on both sides. These protrusions prevent the monotonic arm connecting block from detaching from the first insertion cavity through the side opening. The configuration of the monotonic arm connecting block is consistent with that of the first insertion cavity, both being stepped configurations, and slots for the protrusions to enter are provided at the stepped corners formed by the narrow and wide sections on both sides.

[0008] Further improvements have been made to the slot, which is divided into a sliding part and a locking part along the assembly guide. The protrusion and the sliding part are clearance fit, and the locking part is interference fit.

[0009] Further improvements were made, with the mating clearance between the slot and the protrusion gradually decreasing along the assembly guide.

[0010] Further improvements include an upwardly extending groove on the narrow section of the first insertion cavity and an upwardly extending extension block on the narrow section of the monotonic arm connecting block, with the extension block inserted into the extension groove.

[0011] Further improvements include: the locking hole has symmetrically distributed through slots on both sides of the column that communicate with the locking hole; the locking rod has an anti-disengagement rod that passes through the through slot; the anti-disengagement rod rotates to form a misalignment with the through slot after passing through the through slot; and the monotonic arm connecting block has an insertion hole with the same configuration as the locking hole.

[0012] The beneficial effects of this utility model are:

[0013] This invention not only enables the quick installation of the monoclamp connecting block on the column, but also enables the rapid assembly of the monoclamp connecting block and the monoclamp, eliminating the cumbersome use of bolts as fastening components and achieving convenient assembly.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Referring to the attached diagram: This connection structure for connecting the glass storage cabinet column and the adjustable arms includes a column 1 and several adjustable arms 2. The adjustable arms 2 have a first assembly end face 21, on which a first insertion cavity 22 is provided. A movable adjustable arm connecting block 3 is provided in the first insertion cavity 22. A locking rod 6 is provided on the adjustable arm connecting block 3 to fix it to the column 1. The column 1 has a second assembly end face 11 that contacts the first assembly end face 21. A second insertion cavity 12 is provided on the second assembly end face 11. The second insertion cavity 12 has multiple locking holes 4 on the column 1 to fix the corresponding adjustable arm connecting block 3 at the final assembly position of the column 1. The locking rod 6 is combined with the locking holes 4 and locked by rotation. The principle of this utility model is that the monotonic arm connecting block 3 is pre-set on the column 1, and the final assembly position of the monotonic arm connecting block 3 on the column 1 is quickly determined by the combination of the locking rod 6 and the locking hole 4. After the assembly position is determined, the locking rod 6 and the locking hole 4 are used to lock the monotonic arm connecting block 3 in the final assembly position. The locking rod 6 and the locking hole 4 do not require nuts. Since the monotonic arm 2 is used to connect containers for storing items (storage frames with drawers, storage frames with transparent glass, etc.), there are multiple monotonic arm connecting blocks 3 set on the column 1. After the monotonic arm connecting block 3 is set, the monotonic arm 2 is inserted into the monotonic arm connecting block 3 through the first insertion cavity 22. The insertion method is simple and convenient, and the assembly connection of the two can be completed quickly. When disassembly is required later, the monotonic arm 2 can be pulled out directly without removing the monotonic arm connecting block 3 from the column 1.

[0021] The first insertion cavity 22 is provided with a lower opening 221 on the monotonic arm 2 to allow the monotonic arm connecting block 3 to enter the first insertion cavity 22, and a side opening 222 to allow part of the monotonic arm connecting block 3 to extend out of the first insertion cavity 22. When the monotonic arm 2 is provided with the monotonic arm connecting block 3, the lower opening 221 allows the monotonic arm connecting block 3 to enter the first insertion cavity 22. Since part of the monotonic arm connecting block 3 needs to enter the second insertion cavity 12 to connect with the column 1, the side opening 222 is provided so that part of the monotonic arm connecting block 3 can extend out of the first insertion cavity 22.

[0022] The first insertion cavity 22 has a stepped configuration, and inwardly extending protrusions 223 are provided at the stepped corners formed by the narrow and wide sections on both sides. These protrusions 223 prevent the monotonic arm connecting block 3 from detaching from the first insertion cavity 22 through the side opening 222. The configuration of the monotonic arm connecting block 3 is consistent with that of the first insertion cavity 22, both being stepped, and slots 31 for the protrusions 223 to enter are provided at the stepped corners formed by the narrow and wide sections on both sides. This configuration ensures that when the monotonic arm 2 is inserted into the monotonic arm connecting block 3, it can only be inserted through the lower opening 221 and not through the side opening 222. Firstly, this design ensures that the assembly direction of the two components is limited to a single direction during connection and assembly. When the monotonic arm 2 is inserted into the monotonic arm connecting block 3, it can satisfy the principle of downward gravity. After the monotonic arm 2 is connected to the storage frame with a storage drawer, the storage frame with transparent glass, etc., the gravity brought by these storage components also allows the monotonic arm 2 to be set more stably on the monotonic arm connecting block 3. Moreover, under the constraint of the protrusion 223 and the slot 31, the monotonic arm 2 will not detach from the monotonic arm connecting block 3 from the side due to gravity. At the same time, the protrusion 223 and the slot 3 are also assembled together after insertion.

[0023] The slot 31 is divided into a sliding part 311 and a locking part 312 along the assembly guide. The protrusion 223 is clearance-fitted with the sliding part 311 and interference-fitted with the locking part 312. The clearance-fit with the sliding part 311 allows the protrusion 223 to slide along the assembly guide, and the interference-fit with the locking part 312 locks the protrusion 223 in the locking part 312, so as to complete the assembly connection of the monotonic arm connecting block 3 and the monotonic arm 2. Such connection assembly is suitable for quick assembly and convenient assembly.

[0024] The mating gap between the slot 31 and the protrusion 223 gradually decreases along the assembly guide, meaning that the change in slot width is linear, making the insertion process relatively smooth and avoiding jamming during the connection assembly.

[0025] The narrow section of the first insertion cavity 22 has an upwardly extending extension groove 224 on the monotonic arm 2, and the narrow section of the monotonic arm connecting block 3 has an upwardly extending extension block 32 on the monotonic arm connecting block 3. The extension block 32 is inserted into the extension groove 224. This arrangement can further increase the connection stability between the monotonic arm connecting block 3 and the monotonic arm 2, and also make the monotonic arm connecting block 3 have better load-bearing capacity. At the same time, it can quickly clarify the setting form of the monotonic arm connecting block 3 on the column 1, that is, the end face of the extension block 32 is not the same as the first assembly end face 21, that is, it is also away from the second assembly end face 11.

[0026] The locking hole 4 has symmetrically distributed through slots 41 on both sides of the column 1, which communicate with the locking hole 4. The locking rod 6 has an anti-disengagement rod 61 that passes through the through slot 41. After passing through the through slot 41, the anti-disengagement rod 61 rotates to form a misalignment with the through slot 41. The single-arm connecting block 3 has a socket 33 with the same configuration as the locking hole 4. This design eliminates the need for the cumbersome bolt connection, which requires a nut. Since the column is a profile, its structural principle makes it difficult to provide sufficient operating space for the operator. Therefore, using bolts and nuts to lock the components would increase the assembly difficulty. The locking rod 6 uses the anti-disengagement rod 61 as the locking component. That is, the anti-detachment rod 61 is inserted into the locking hole 4 along with the locking rod 6, and the anti-detachment rod 61 enters the through groove 41. After the anti-detachment rod 61 has completely passed through the through groove 41, the position of the anti-detachment rod 61 is changed by rotating the locking rod 6, that is, the anti-detachment rod 61 and the slot 41 are misaligned. In this way, the anti-detachment rod 61 cannot enter the through groove 41, thereby limiting the locking rod 6 to the column 1. At the same time, the single-adjustment arm connecting block 3 is provided with a plug hole 33 with the same structure as the locking hole 4. Its connection method is the same as the connection method of the locking rod 4 and the locking hole 4 on the column 1. So, when the locking rod 4 and the column 1 are locked together, the single-adjustment arm connecting block 3 can also be fixed to the column 1.

[0027] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
