Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to a communication cabinet base component and a communication cabinet thereof. Background Art

[0002] A corresponding communication cabinet base assembly is arranged at the bottom of the cabinet, and the cabinet is separated from the ground by the communication cabinet base assembly to prevent the cabinet from getting wet. At the same time, the communication cabinet base assembly also has rollers, and the cabinet can be easily moved by the rollers.

[0003] The existing communication cabinet base assembly usually directly connects multiple rollers to the bottom of the cabinet. During the connection process, the cabinet needs to be turned over or the bottom of the cabinet needs to be supported. It can be seen that when the cabinet is turned over to install the rollers, due to the large size and weight of the cabinet, the installation and removal of the rollers is time-consuming and laborious, and the safety is not high.

[0004] When loading and unloading the rollers after supporting the bottom of the cabinet, a support device is required. Whether the support device is in place and safe depends on the experience of the operator, which leads to high requirements for loading and unloading. At the same time, this method of loading and unloading also involves the step of lifting the cabinet, and the loading and unloading of rollers is still time-consuming and laborious.

[0005] Chinese patent publication number CN103167761A discloses a cabinet base, including a base body, on which a cabinet connection component and a height adjustment component are arranged; the base body is a concave structure, and parallel and / or staggered reinforcing ribs are arranged on the back of the base body.

[0006] The cabinet base of the above patent is made of plastic material and is obtained by injection molding. In order to make the cabinet base made of plastic material have better strength and rigidity, the present invention improves the structural design of the cabinet base. After adopting the new structure, the plastic cabinet base of the present invention has higher strength and rigidity, and can effectively suppress the deformation of the cabinet base after being subjected to pressure, thereby improving the safety of the cabinet base. It can better replace the cabinet base made of steel material, thereby achieving the purpose of replacing steel with plastic and reducing costs.

[0007] It can be seen that the above patent only solves the problem that the bottom of the cabinet is easily affected by moisture through the height adjustment component, and does not provide a specific solution for how to conveniently load and unload rollers at the bottom of the cabinet. There is also the problem that when installing rollers at the bottom of the cabinet, the operation is cumbersome and labor-intensive. And the connection strength of the main structure of the communication cabinet needs to be further improved. Summary of the invention

The number of the above-mentioned crossbeams and the number of the connecting blocks are both four. The four connecting blocks are respectively located at the four corners of the bottom plate. The above-mentioned crossbeam is connected between the corresponding two adjacent connecting blocks. The four connecting blocks and the four crossbeams are connected to form a frame-shaped bottom frame. The outer edge of the above-mentioned bottom plate is fixedly connected to the inner edge of the bottom frame. The above-mentioned support assembly is located at the lower part of the connecting block, and the above-mentioned roller assembly is connected to the lower part of the crossbeam.

[0011] The connecting block is L-shaped, and both ends of the L-shape of the connecting block are connecting ends, and the ends of the cross beams are connected to the connecting ends.

[0012] The connecting block comprises a frame and a bottom shell, the lower part of the frame is a cavity and has reinforcing ribs at the lower part of the frame to increase the strength of the frame, the bottom shell is fixedly connected to the lower part of the frame and the reinforcing ribs are covered between the frame and the bottom shell, and the connecting end is located at the end of the frame.

[0013] The bottom shell is flush with the outer side of the cross beam.

[0014] The pre-support assembly comprises a cylindrical connecting tube and a rod-shaped supporting rod on the frame, the upper end of the supporting rod is embedded in the connecting tube and the two are threadedly connected, and the lower end of the supporting rod has a flexible supporting pad.

[0015] The connecting tube, frame and reinforcing ribs are all integrated structures and the connecting tube is located between the angles of the two connecting ends.

[0016] The reinforcing rib extends from one side of the frame to the other side, and the connecting tube is connected to one end of the reinforcing rib.

[0017] The size of the support pad is larger than that of the support rod.

[0018] The cross beam is cylindrical, and the connection end is a convex block protruding from the end of the frame. There are several convex blocks, which are arranged adjacent to each other with gaps between them, and the outer edges of all the convex blocks are against the inner side of the cross beam.

[0019] The roller assembly includes a roller, a roller seat and a connecting plate, the connecting plate includes a connecting part one, a connecting part two and a connecting part three, the connecting part two is L-shaped, the connecting part one and the connecting part three are respectively fixedly connected at two ends of the L-shape of the connecting part two, the upper part of the connecting part one is in contact with and fixedly connected to the lower side surface of the beam, the connecting part three is in contact with and fixedly connected to the inner side surface of the beam, the upper end of the roller seat is fixedly connected to a lower part of the connecting part, the roller is movably connected to the roller seat, and the upper part of the connecting part two is against the lower part of the base plate.

[0020] The second object of the present invention can be achieved by the following technical solutions: A communication cabinet comprises a cabinet body with a hollow interior, the cabinet body is connected to the upper part of a communication cabinet base assembly, the communication cabinet base assembly is connected to a communication cabinet top assembly via four column beams, the lower ends of the column beams are respectively abutted against the connecting blocks of the communication cabinet base assembly, and each of the column beams is provided with a bracket fixing arm, the lower end of which abuts against the top surface of the cross beam.

[0021] The communication cabinet can be stably placed on the ground through the communication cabinet base assembly at the bottom, and the position of the communication cabinet can be conveniently changed according to actual needs.

[0022] Compared with the prior art, the communication cabinet base assembly can facilitate loading and unloading between the roller assembly and the crossbeam under the action of the pre-support assembly, and the pre-support assembly is arranged on the connecting block, and the roller assembly is arranged on the crossbeam. Therefore, the entire communication cabinet base assembly has a compact structure and the pre-support assembly and the roller assembly will not interfere with each other, which effectively ensures the stability of the communication cabinet base assembly and its structure is relatively compact.

[0023] At the same time, the roller assembly not only makes the entire communication cabinet base assembly easy to move, but also supports the bottom plate. Under the premise of ensuring the compact structure of the communication cabinet base assembly, its stability is relatively high and has high practical value.

[0024] In addition, the communication cabinet with the roller assembly can be conveniently moved and the roller assembly can be conveniently inspected and maintained. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly mounted on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0035] Embodiment 1, as Figure 1 and Figure 2 and Figure 3 and Figure 4 As shown, the base assembly of the communication cabinet includes a rectangular bottom plate 1, and also includes a crossbeam 2, a connecting block 3, a pre-support assembly and a roller assembly. The number of the above-mentioned crossbeams 2 and the number of the connecting blocks 3 are both four. The four connecting blocks 3 are respectively located at the four corner positions of the bottom plate 1. The above-mentioned crossbeam 2 is connected between the corresponding adjacent two connecting blocks 3. After the four connecting blocks 3 and the four crossbeams 2 are connected, a frame-shaped bottom frame is formed. The outer edge of the above-mentioned bottom plate 1 is fixedly connected to the inner edge of the bottom frame, the above-mentioned support assembly is located at the lower part of the connecting block 3, and the above-mentioned roller assembly is connected to the lower part of the crossbeam 2.

[0036] After the four cross beams 2 are orderly connected between two adjacent connection blocks 3, the four cross beams 2 and the four connection blocks 3 form a square bottom frame. Since the outer edge of the bottom plate 1 is connected to the inner edge of the bottom frame, the bottom frame and the bottom plate 1 can be stably connected.

[0037] At the same time, the pre-support assembly is arranged at the connection block 3, and the roller assembly is arranged at the crossbeam 2. Such a structure can avoid mutual interference between the pre-support assembly and the roller assembly, and effectively improve the stability of the entire communication cabinet base assembly.

[0038] The roller assembly is in contact with the ground, ensuring that the base assembly of the communication cabinet can be easily moved. Since the pre-support assembly extends out from the bottom of the bottom plate, the bottom frame and the bottom plate 1 can be prevented from contacting the ground during loading and unloading.

[0039] Of course, the dimension of the roller assembly extending from the bottom of the base plate 1 is greater than the dimension of the pre-support assembly extending from the bottom of the base plate 1. Such a structure can prevent the pre-support assembly from contacting the ground during normal operation.

[0040] The connecting block 3 is L-shaped, and both ends of the L-shape of the connecting block 3 are connecting ends 3a2, and the ends of the cross beam 2 are connected to the connecting ends 3a2.

[0041] Since two adjacent cross beams 2 are arranged at 90 degrees, the L-shaped connecting block 3 can be stably connected between the ends of the two adjacent cross beams 2 .

[0042] The connecting block 3 includes a skeleton 3a and a bottom shell 3b, the lower part of the skeleton 3a is a cavity and has reinforcing ribs 3a1 at the lower part of the skeleton 3a to increase the strength of the skeleton 3a, the bottom shell 3b is fixedly connected to the lower part of the skeleton 3a and the reinforcing ribs 3a1 are covered between the skeleton 3a and the bottom shell 3b, and the connecting end 3a2 is located at the end of the skeleton 3a.

[0043] The connection block 3 formed by connecting the frame 3a and the bottom shell 3b has a cavity inside, which can reduce the weight of the connection block 3 and appropriately reduce the cost.

[0044] At the same time, the reinforcement ribs 3a1 can ensure that the entire connecting block 3 also has sufficient strength.

[0045] The bottom shell 3 b is flush with the outer side of the cross beam 2 .

[0046] This can improve the structural compactness of the entire communication cabinet base assembly.

[0047] The pre-support assembly includes a cylindrical connecting tube 3a3 and a rod-shaped supporting rod 4 on the frame 3a. The upper end of the supporting rod 4 is embedded in the connecting tube 3a3 and the two are threadedly connected. The lower end of the supporting rod 4 has a flexible supporting pad 5.

[0048] After the support rod 4 is rotated, the support rod 4 can move up and down relative to the connecting tube 3a3.

[0049] That is to say, during the loading and unloading process, the lower end of the support rod 4 extends out of the roller assembly. After the lower end of the support rod 4 contacts the ground, the roller assembly can be prevented from contacting the ground, which facilitates the loading and unloading operation between the roller assembly and the crossbeam 2.

[0050] Of course, after the installation between the roller assembly and the cross beam 2 is completed, the support rod 4 rotates in the opposite direction, and the upwardly moved support rod 4 ensures that the roller assembly is in normal contact with the ground again.

[0051] The connecting tube 3a3, the frame 3a and the reinforcing rib 3a1 are all integral structures and the connecting tube 3a3 is located between the angles of the two connecting ends 3a2.

[0052] This not only ensures the compactness of the structure of the connecting block 3, but also ensures the strength of the entire skeleton 3a.

[0053] The reinforcing rib 3a1 extends from one side of the frame 3a to the other side, and the connecting tube 3a3 is connected to one end of the reinforcing rib 3a1.

[0054] The reinforcing ribs 3a1 extend transversely in the frame 3a to ensure that the frame 3a has sufficient strength.

[0055] The size of the support pad 5 is larger than that of the support rod 4 .

[0056] The support pad 5 is made of rubber material. The support pad 5 with a relatively large size can ensure that the lower end of the support rod 4 can stably rest against the ground.

[0057] The cross beam 2 is cylindrical, and the connecting end 3a2 is a protrusion 3a21 protruding from the end of the frame 3a. There are several protrusions 3a21, which are arranged adjacent to each other with gaps between adjacent protrusions 3a21. The outer edges of all protrusions 3a21 are against the inner side of the cross beam 2.

[0058] After a number of adjacent protrusions 3a21 are embedded in the cross beam 2, the protrusions 3a21 are pressed tightly against the inner side of the cross beam 2, thereby ultimately ensuring that the connection between the connecting end 3a2 and the end of the cross beam 2 is not only fast but also has a relatively high connection stability.

[0059] The roller assembly includes a roller 6, a roller seat 7 and a connecting plate 8, the connecting plate 8 includes a connecting portion 1 8a, a connecting portion 2 8b and a connecting portion 3 8c, the connecting portion 2 8b is L-shaped, the connecting portion 1 8a and the connecting portion 3 8c are respectively fixedly connected to the two ends of the L-shape of the connecting portion 2 8b, the upper portion of the connecting portion 1 8a is in contact with and fixedly connected to the lower side surface of the cross beam 2, the connecting portion 3 8c is in contact with and fixedly connected to the inner side surface of the cross beam 2, the upper end of the roller seat 7 is fixedly connected to the lower portion of the connecting portion 1 8a, the roller 6 is movably connected to the roller seat 7, and the upper portion of the connecting portion 2 8b is against the lower portion of the base plate 1.

[0060] The connection part 1 8a is in the shape of a flat plate and is arranged horizontally, and the connection part 3 8c is in the shape of a flat plate and is arranged vertically. The connection part 1 8a and the connection part 3 8c are stably connected through the connection part 2 8b.

[0061] Since the cross beam 2 is in a rod shape and has a limited width, and the upper dimension of the roller seat 7 is larger than the width of the cross beam 2, the roller seat 7 can be stably connected to the cross beam 2 through the connecting portion 8a.

[0062] Specifically, the crossbeam 2 with a relatively small width dimension effectively reduces the material consumption of the crossbeam 2 , ensuring that the cost is relatively low while simplifying the overall structure.

[0063] After the connection portion 3 8 c is connected to the side of the cross beam 2 , the connection stability between the entire connection block 3 and the cross beam 2 can be ensured.

[0064] At the same time, the upper part of the second connecting part 8b abuts against the lower part of the bottom plate 1, providing appropriate support for the bottom plate 1, and ultimately ensuring a stable connection between the bottom plate 1 and the bottom frame.

[0065] The base plate 1 includes a base plate 1a and a base plate 1b. The base plate 1a and the base plate 1b are both rectangular flat plates. The base plate 1a and the base plate 1b are spliced ​​together to form the above-mentioned base plate 1. The base plate 1b has a penetrating connection hole 1b2, and the connection hole 1b2 is connected to an air outlet 9.

[0066] The tuyere 9 is an existing fireproof tuyere, and therefore, the specific technical features of the tuyere 9 are not described in detail in the embodiment.

[0067] The bottom plate 1a has a downwardly folded contact portion 1a1 at its edge, and the bottom plate 2 1b has a downwardly folded contact portion 1b1 at its edge. The contact portion 1a1 and the contact portion 2 1b1 between the adjacent bottom plates 1a and 1b are in surface contact.

[0068] Under the action of the contact part 1a1 and the contact part 2 1b1, the bottom plate 2 1b is prevented from overlapping and warping with the bottom plate 1 1a, thereby ensuring that the flatness of the entire bottom plate is relatively high.

[0069] The air outlet 9 is detachably connected to the connection hole 1b2, which can ensure that the base assembly of the communication cabinet has a good passing effect. At the same time, it can also prevent relatively large debris or small animals from passing through the connection hole.

[0070] The communication cabinet base assembly can facilitate loading and unloading between the roller assembly and the crossbeam under the action of the pre-support assembly, and the pre-support assembly is arranged on the connecting block, and the roller assembly is arranged on the crossbeam. Therefore, the entire communication cabinet base assembly has a compact structure and the pre-support assembly and the roller assembly will not interfere with each other, which effectively ensures the stability of the communication cabinet base assembly and its structure is relatively compact.

[0071] At the same time, the roller assembly not only makes the entire communication cabinet base assembly easy to move, but also supports the bottom plate. Under the premise of ensuring the compact structure of the communication cabinet base assembly, its stability is relatively high and has high practical value.

[0072] The roller seat and roller in the roller assembly are both prior art, the roller can rotate freely and swing relative to the bottom plate, and there is also a locking function between the roller and the roller seat, so that the roller can be locked at the roller seat. Since the existing roller and roller seat can both achieve the above functions, the technical features of the locking part between the roller seat and the roller, and the technical features of the connection between the roller and the roller seat are not repeated in the embodiments.

[0073] In addition, the communication cabinet with the roller assembly can be conveniently moved and the roller assembly can be conveniently inspected and maintained.

[0074] Embodiment 2, based on embodiment 1, as Figure 3 and Figure 5-Figure 6 As shown, this embodiment further discloses the following contents: the inner facade of each of the four cross beams 2 is horizontally extended with a supporting cantilever block 20, the length of the supporting cantilever block 20 is equal to the length of the cross beam 2, and at the same time, a corner cantilever block 30 is provided on the inner facade of each connecting block 3, and the facing ends of two adjacent supporting cantilever blocks 20 are against the two side surfaces of the corner cantilever block 30 to form a supporting annular portion, and the outer edge of the bottom plate 1 is placed on the supporting annular portion and locked by fasteners to complete the assembly. In terms of space utilization, the supporting cantilever block 20 and the corner cantilever block 30 are provided in the middle of the inner facade of this embodiment, which can make the position design of the bottom plate 1 more reasonable, so that the internal vertical space can be maximized.

[0075] Secondly, the crossbeam 2 of the present embodiment includes a top supporting portion 21, an inner facade supporting portion 22 connected to the inner side of the top supporting portion 21, and an outer curved portion 23 connecting the outer side of the top supporting portion 21 and the bottom side of the inner facade supporting portion 22. A reinforcing rib 24 is respectively connected to the center position of the inner wall of the top supporting portion 21, the inner facade supporting portion 22 and the outer curved portion 23. Three reinforcing ribs 24 are connected to the outer wall of the central cylindrical portion 25. Among them, the reinforcing rib 24 connected to the top supporting portion 21 and the reinforcing rib 24 connected to the inner facade supporting portion 22 are vertically distributed, while the remaining reinforcing rib 24 and the above two reinforcing ribs 24 are respectively distributed at obtuse angles.

[0076] The supporting cantilever block 20 is connected to the inner facade support portion 22. At least part of the connecting plate 8 is connected to the lower surface of the supporting cantilever block 20. The fixing of the connecting plate 8 can be made more stable, thereby improving the stability of the roller assembly. Secondly, through the above design, it can be ensured that the protrusion 3a21 can extend into the space formed by the two adjacent reinforcing ribs 24, which can improve the docking efficiency and the structural strength of the connection.

[0077] Through the above structural design, the top support part 21 and the inner facade support part 22 connected to the inner side of the top support part 21 combined with the reinforcing ribs 24 can have very good structural strength in both the horizontal and vertical directions to improve the rigidity of the beam 2.

[0078] Embodiment 3, as Figure 6 As shown, the present embodiment further discloses a communication cabinet, which includes a cabinet body with a hollow interior, the cabinet body is connected to the upper part of the communication cabinet base assembly of Example 1, the communication cabinet base assembly is connected to the communication cabinet top assembly 11 through four column beams 10, the structure of the communication cabinet top assembly 11 is missing the roller assembly of the communication cabinet base assembly, and the rest of the structure is basically the same as the communication cabinet base assembly, and this embodiment will not be further elaborated, the lower ends of the column beams 10 are abutted against the connecting blocks 3 of the communication cabinet base assembly one by one, and each column beam 10 is provided with a bracket fixing arm 10a whose lower end abuts against the top surface of the beam 2.

[0079] The bracket fixing arm 10a has multiple functions: First, the joint gap between the connecting block 3 and the cross beam 2 is crossed to improve the connection strength between the connecting block 3 and the cross beam 2.

[0080] Second, the bracket fixing arm 10 a can laterally fix the bracket 12 inside the communication cabinet, so as to further improve the space utilization inside the communication cabinet and improve the convenience of fixing the bracket 12 .

[0081] Third, the bracket fixing the vertical arm 10 a can improve the structural strength of the column beam 10 .

[0082] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
