Description

Technical Field

[0001] The utility model relates to the technical field of desks, and particularly relates to a screen connection structure without square columns. Background Art

[0002] With the continuous development of social economy, in real life, the scenarios of using screens are becoming more and more extensive. Screens can not only partition spaces but also beautify the environment as decorations. In some office environments, wires need to be arranged inside the screens, which not only meets the usage requirements of electrical equipment but also avoids the safety hazards caused by exposed wires. Therefore, in order to make the screens stably connected and the wires can be reasonably arranged inside the screens, the connection of the screens is reasonably designed to meet the requirements and ensure the safety and reliability of electrical connection.

[0003] For example, a patent document with a patent application number of 201520131457.6 and a publication date of August 26, 2015 discloses a screen, which includes a screen main body. The two sides of the screen main body are respectively fixedly connected to side columns through screws. The side columns are sequentially connected to column B. An A column is arranged outside column B. An A column support is arranged at the bottom of the A column, and a B column support is arranged at the bottom of the B column. The screen also includes a wire. The A column is connected to the B column through a connecting column. Symmetric sliding buckles are arranged on both sides of the connecting column. Chutes matching with the above sliding buckles are respectively arranged on the A column and the B column. The wire sequentially passes through the A column support and the B column support. The structure is firm, the installation and disassembly are convenient, the service life is long, the wire routing structure is ingenious, the wire is not exposed, and it is safe and reliable.

[0004] In the above document, an A column support and a B column support are respectively arranged at the bottoms of the A column and the B column. When the A column and the B column are connected, since the A column support and the B column support are respectively arranged, the A column is arranged outside the B column through the connecting column. When the A column and the B column are connected, it is necessary to first connect the connecting column to the B column and then connect the A column to the connecting column to achieve the connection. Therefore, the A column and the B column are only connected through the connecting column. During long-term use, when relative displacement occurs between the A column and the B column, the connecting column is prone to deformation, thereby affecting the connection firmness between the A column and the B column. It is necessary to use two columns to achieve the connection, so the connection structure is complex, and the connecting column is exposed outside the screen and is easily affected by the external environment, thereby causing damage to the connecting column structure. Summary of the Invention

[0005] The utility model provides a screen connection structure without square columns, which has a simple structure and good connection reliability.

[0006] To achieve the above object, the technical solution of the present utility model is: a screen connection structure without square columns, which is arranged at one end of the screen main body and includes side columns. A support and limit device is arranged between the side columns of two adjacent screen columns. The support and limit device includes a support device and a limit device. The support device includes a bottom support member, and the bottom support member is arranged at the bottoms of two adjacent side columns. The limit device includes a limit plate and a limit column. The limit plate is detachably arranged on the outer sides of two adjacent side columns. A cavity is formed between the limit plate and two adjacent side columns. The inner sides of two adjacent side columns are detachably connected by a connecting column, and the connecting column is located in the cavity.

[0007] With the above settings, a bottom support member is arranged at the bottoms of two adjacent side columns, and two adjacent side columns extend into the same bottom support member. The bottom support member can not only provide support for the side columns, but also limit the horizontal position of the side columns. In addition, a limit plate is arranged on the outer side of the connection of the two side columns, and the inner connection of the two side columns is detachably connected by a connecting column, so that the limit column and the two side columns form a cavity. This can not only facilitate wire routing, but also facilitate the horizontal limitation of the side columns. By setting the limit plate, the stability and safety of the overall structure can be ensured. And the limit plate is arranged on the outer sides of the two side columns, which can protect the internal structure of the side column connection and the limit column structure, preventing external factors from damaging the internal structure of the side column connection. The structure is simple and the connection reliability is good.

[0008] Further, limit protrusions extending towards the middle are respectively arranged on both sides of the side column. A limit groove is formed between the limit protrusion and the outer surface of the side column. The limit protrusion is recessed inward to form a groove portion. The limit protrusions on the inner sides of the two side columns form an inner connection, and the limit protrusions on the outer sides of the two side columns form an outer connection.

[0009] With the above settings, by arranging the limit protrusions and limit grooves on both sides of the side column, a connection position can be provided between the two side columns, making the connection between the side columns simple and allowing for precise docking without complex steps.

[0010] Further, the limit device further includes a connecting member. The limit column is provided with an assembly groove matching the limit protrusions on two adjacent side columns. The limit column is further provided with a limit hole along the axial direction. The connecting member is detachably arranged in the limit hole, and the limit column is arranged at the inner connection.

[0011] With the above settings, the limit post is provided with an assembly groove that matches the limit protrusion. When the side post extends into the assembly groove of the limit post through the limit protrusion, an accurate positioning and stable connection can be formed, which not only provides axial positioning but also restricts the side post from moving in the horizontal direction, thereby enhancing the overall structural stability. And a limit hole is provided in the limit post, and the limit block is used to accommodate a connecting piece, such as a screw. By fixing the connecting piece in the limit hole, when the limit post extends into a very deep position in the cavity, in order to facilitate sliding the limit post out of the cavity for disassembly, the connecting piece is set in the limit hole and then the limit post is removed from the limit post through the exposure of the connecting piece, which is convenient for disassembling the limit post.

[0012] Further, the bottom support member includes a bottom support plate. First protrusions are provided along the four - week bottom of the bottom support plate. Second protrusions that match the limit grooves are provided on the bottom support plate, and the bottom support plate is further provided with third protrusions.

[0013] With the above settings, first protrusions are provided around the bottom support member. When the side post and the limit plate extend into the bottom support member, the outer sides of the side post and the limit plate can be limited by the first protrusions to ensure the relative positions between the side post and the limit plate. Second protrusions that match the limit grooves are provided on the bottom support member. When the side post extends into the bottom support member, not only can it be limited by the first protrusions, but also the second protrusions can extend into the limit grooves of the side plate for limitation, further strengthening the connection firmness between the bottom support member and the side plate. The bottom support member is provided with third protrusions, and the setting of the third protrusions provides a limiting effect on the limit plate.

[0014] Further, inward and upward depressions are respectively formed on the two side walls of the limit plate to form installation grooves that match the third protrusion parts. A boss corresponding to the groove part is provided on the outer side wall of the installation groove, and the limit plate is arranged at the outer connection part.

[0015] With the above settings, the limit plate is provided with a boss, and the boss fits with the groove part on the side post. When the limit plate extends between the two side posts, the groove part can provide displacement guidance for the limit plate, and the limit plate is provided with an installation groove. When the limit plate extends into the bottom support member, the third protrusion and the installation groove can fit with each other to complete the fixation of the limit plate.

[0016] Further, the limit device further includes a limit block. The limit block is provided with a protrusion part that matches the limit groove on the side post, and the limit block is arranged on the tops of two adjacent side posts.

[0017] With the above settings, by arranging the limit block on the tops of the two side posts, and the limit block is provided with a protrusion part that matches the limit groove, it can ensure that the limit block is accurately embedded into the limit groove on the top of the side post, thereby forming a stable and reliable connection, which not only enhances the structural stability between the side posts but also effectively prevents the displacement or separation of the top of the side post caused by external forces.

[0018] Furthermore, a fourth protrusion is provided on the limiting block and is arranged to match the groove portion at the inner connection.

[0019] With the above arrangement, the top parts of two adjacent side columns can be horizontally limited by inserting the fourth protrusion into the groove portion at the inner connection.

[0020] Furthermore, through holes are provided on the side wall of the side column.

[0021] With the above arrangement, through holes are provided at the relative positions of the side columns, and wires can be arranged to pass through a screen body through the through holes and extend into another screen body. Moreover, a cavity is formed between the side column and the limiting plate, which will not block the wires from passing through. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1.

[0034] As Figures 1-8 shown, a screen connection structure without square columns is provided on one side of the screen body 1. A side column 4 is fixedly arranged on one side of the screen body 1. A support and limiting device is arranged between the two side columns 4. The support and limiting device includes a support device and a limiting device. The support device includes a bottom support member 2, and the bottom support member 2 is arranged at the bottoms of the two side columns 4. The limiting device includes a limiting plate 3, and the limiting plate 3 is arranged between the two side columns 4. A cavity is formed between the limiting plate 3 and the side column 4. A bottom support member 2 is arranged at the bottoms of the two side columns 4. The side column 4 is inserted into the bottom support member 2. The bottom support member 2 can not only provide a supporting effect for the side column 4, but also limit the horizontal position of the side column 4. And a limiting plate 3 is arranged at the connection of the two side columns 4. In this embodiment, two adjacent side columns 4 are vertically arranged. By arranging the limiting plate 3, the stability and safety of the overall structure can be ensured. And the arrangement of the limiting plate 3 is located outside the two side columns 4, which can protect the internal structure at the connection of the side columns 4 and prevent external factors from damaging the internal structure at the connection of the side columns 4.

[0035] As Figures 1-6 shown, limiting protrusions 41 extending towards the middle are respectively arranged on both sides of the side column 4. A limiting groove 42 is formed between the limiting protrusion 41 and the outer surface of the side column. The limiting protrusion 41 is recessed inward to form a groove portion 411. The inner limiting protrusions 41 of the two side columns 4 form an inner connection 7, and the outer limiting protrusions 41 of the two side columns 4 form an outer connection 8. By arranging the limiting protrusions 41 and the limiting grooves 42 on both sides of the side column 4, a connection position can be provided between the two side columns 4, making the connection between the side columns 4 simple and enabling precise docking without complex steps.

[0036] The limiting device further includes a limiting post 5 and a connecting piece 52. The limiting post 5 is provided with an assembly groove 51 that matches the limiting protrusion 41. Along the axial direction of the limiting post 5, a limiting hole 53 is also provided. The connecting piece 52 is detachably arranged in the limiting hole 53. The limiting post 5 is arranged at the inner connection 7. The limiting post 5 is provided with an assembly groove 51 that matches the limiting protrusion 41. When the side post 4 extends into the assembly groove 51 of the limiting post 5 through the limiting protrusion 41, an accurate positioning and stable connection can be formed, which not only provides axial positioning but also restricts the side post 4 from moving in the horizontal direction, thereby enhancing the overall structural stability. And a limiting hole 53 is provided in the limiting post 5, such as a screw. By fixing the connecting piece 52 in the limiting hole 53, when it is necessary to remove the limiting post 5 from the cavity, the connecting piece 52 is arranged in the limiting hole 53, and then the connecting piece 52 is exposed, so that the limiting post 5 can be pulled out by pulling the connecting piece 52 to achieve disassembly.

[0037] On both side walls of the limiting plate 3, inward and upward depressions are respectively formed to form installation grooves 32 that are arranged in a matching manner with the third protrusion parts. On the outer side wall of the installation groove 32, a boss 31 corresponding to the groove part is provided. The limiting plate 3 is arranged at the outer connection 8. On the outer side wall of the installation groove 32 of the limiting plate 3, a boss 31 is provided. The boss 31 fits with the groove part 411 on the side post 4. In this embodiment, the limiting plate 3 is arranged as an arc-shaped plate. When the limiting plate 3 extends between the two side posts 4, the groove part 411 can provide displacement guidance for the limiting plate 3. And the limiting plate 3 is provided with an installation groove 32. When the limiting plate 3 extends into the bottom support member 2, the upper and lower direction limiting and fixing of the limiting plate 3 can be completed through the matching of the third protrusion 23 and the installation groove 32.

[0038] As Figure 7 As shown, the bottom support member 2 includes a bottom support base plate 20. Along the four-week bottom of the bottom support base plate 20, a first protrusion 21 extends upward.

The bottom support member 2 is further provided with a third protrusion 23. The first protrusion 21 is arranged around the bottom support member 2. In this embodiment, the number of the second protrusions 22 is 4, and the number of the third protrusions 23 is 2. When the side post 4 and the limiting plate 3 extend into the bottom support member 2, the outer sides of the side post 4 and the limiting plate 3 can be limited by the first protrusion 21 to ensure the relative positions between the side post 4 and the limiting plate 3. The bottom support member 2 is arranged with a second protrusion 22 that matches the limiting groove 42. When the side post 4 extends into the bottom support member 2, not only can it be limited by the first protrusion 21, but also the second protrusion 22 can extend into the limiting groove 42 of the side plate for limiting, further strengthening the connection firmness between the bottom support member 2 and the side plate. The bottom support member 2 is provided with a third protrusion 23, and the setting of the third protrusion 23 provides a limiting function for the limiting plate 3.

[0039] The limiting device further includes a limiting block 6. The limiting block 6 is provided with a protruding portion 61 that matches the limiting groove 42. The limiting block 6 is arranged on the tops of the two side columns 4. By arranging the limiting block 6 on the tops of the two side columns 4 and providing the protruding portion 61 on the limiting block 6 that matches the limiting groove 42, in this embodiment, the number of the protruding portions 61 is 4. A fourth protrusion 62 is arranged on the limiting block 6, and the fourth protrusion 62 is correspondingly arranged with the groove portion 411 of the inner connection portion 7, which can ensure that the limiting block 6 is accurately embedded in the limiting groove 42 at the top of the side column 4, thus forming a stable and reliable connection, not only enhancing the structural stability between the side columns 4, but also effectively preventing the displacement or separation of the tops of the side columns 4 caused by external forces.
