Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to a buffer connection structure of a side plate in a communication cabinet. Background Art

[0002] A communication cabinet is a cabinet used to install and protect communication equipment. It is widely used in data centers, telecommunication rooms, enterprise networks, etc. Its main function is to provide a safe and stable operating environment for communication equipment, while facilitating management and maintenance.

[0003] Existing communication cabinets are usually single-structure metal cabinets with gaps between adjacent side panels. Small vibrations generated during the operation of communication equipment can cause resonance in the communication cabinet, which not only affects the normal operation of the communication equipment, but also causes noise from the loose side panels.

[0004] Moreover, when the communication cabinet is subjected to external force, the vibration will be directly transmitted to the communication equipment, affecting the normal operation of the communication equipment, and its stability is relatively poor.

[0005] A Chinese patent with publication number CN217936358U discloses a transformer communication cabinet with good protection for outdoor use, comprising a communication cabinet body, a signal transmitter fixedly installed on the top of the inner surface of the communication cabinet body, a small transformer fixedly installed on the inner surface of the communication cabinet body, a porous wire connector fixedly installed on the inner surface of the communication cabinet body, a high-voltage display screen and a low-voltage display screen electrically connected to the outer surfaces of the porous wire connector, a device protection structure is arranged inside the communication cabinet body, and a fixed limit structure is arranged inside the communication cabinet body.

[0006] The traditional substation communication cabinet does not have a heat dissipation structure, which makes it impossible for the internal heat to dissipate quickly. At the same time, there is no waterproof layer, which makes the communication box easy to be damaged when in use. This communication cabinet adds heat dissipation holes at the bottom and a heat insulation layer inside, which makes it more convenient to protect the communication cabinet for long-term operation.

[0007] It can be seen that the communication cabinet of the above patent has only made improvements in the heat dissipation of the cabinet in order to solve the stability problem. No substantial solution has been proposed for the resonance generated during the use of the communication cabinet and the impact of the communication cabinet on the communication equipment after being subjected to external forces. It also has the problem of poor stability. Summary of the invention

[0008] The object of the present invention is to provide a buffer connection structure for side panels in a communication cabinet with high stability and compact structure in view of the above problems existing in the prior art.

[0009] The purpose of the present invention can be achieved by the following technical solutions: A buffer connection structure for side panels in a communication cabinet, the communication cabinet comprising a cabinet body with a cavity inside and a square frame-shaped cross section, the cabinet body comprising four plate-shaped side panels, the four side panels being connected end to end to form the cabinet body with the square frame-shaped cross section, the buffer connection structure comprising a connecting edge one, a connecting edge two, a baffle rod and an elastic pre-tightening component, the adjacent two side panels are side panel one and side panel two respectively, the inner side of the baffle rod has a concave positioning notch along its length direction, the side panel one and the side panel two are both embedded in the positioning notch, the connecting edge one is located at the inner edge of the side panel one, the connecting edge two is located at the inner edge of the side panel two, the connecting edge one and the connecting edge two are both located at the positioning notch, the elastic pre-tightening component is located between the connecting edge one and the connecting edge two, and under the action of the elastic pre-tightening component, the inner edge of the side panel one and the inner edge of the side panel two can be stably and tightly connected at the positioning notch.

[0010] In the buffer connection structure of the side plate in the communication cabinet, the cross section of the blocking rod is L-shaped, the side plate 1 contacts one inner side surface of the blocking rod, and the side plate 2 contacts the other inner side surface of the blocking rod.

[0011] In the buffer connection structure of the side panel in the above-mentioned communication cabinet, the connecting edge one is a connecting tube fixedly connected to one edge of the side panel and is in the shape of a tube, the connecting edge two is in the shape of a plate and protrudes from the inner side of the side panel two, one end of the above-mentioned elastic pre-tensioning component is connected in the connecting tube, and the other end of the elastic pre-tensioning component contacts two surfaces of the connecting edge.

[0012] In the buffer connection structure of the side panel of the above-mentioned communication cabinet, the elastic preload assembly includes contact piece one, contact piece two, a hinge shaft and a torsion spring. The hinge shaft, contact piece two and the inner end of contact piece one are all located in the connecting tube. The inner end of contact piece one and the inner end of contact piece two are both hinged on the hinge shaft. The torsion spring acts on contact piece one and contact piece two. Under the elastic force of the torsion spring, the outer end of contact piece two has a tendency to abut against the connecting tube, and the outer end of contact piece one has a tendency to abut against connecting edge two.

[0013] In the buffer connection structure of the side plate of the above-mentioned communication cabinet, the contact piece 1 includes a pressing piece 1, a connecting piece 1, a connecting piece 2 and an articulated tube 1. The pressing piece 1 is rectangular, and the connecting piece 1 and the connecting piece 2 are both long sheets. The connecting piece 2 is arranged parallel to the pressing piece 1. The two ends of the connecting piece 1 are respectively fixedly connected to the inner end of the pressing piece 1 and the inner end of the connecting piece 2. The articulated tube 1 is fixedly connected to the outer end of the connecting piece 2 and the articulated tube is installed on the articulated shaft. The side of the connecting tube has a penetrating avoidance hole, and the connecting piece 1 is penetrated at the avoidance hole.

[0014] In the buffer connection structure of the side plate in the above-mentioned communication cabinet, the pressing plate 1, the connecting plate 1, the connecting plate 2 and the hinge cylinder 1 are an integrated structure.

[0015] In the buffer connection structure of the side panel of the above-mentioned communication cabinet, the length dimension of the hinge shaft is greater than the length dimension of the hinge cylinder 1 and the hinge cylinder 1 is located in the middle part of the hinge shaft, the number of the above-mentioned contact pieces 2 is two, and the two contact pieces 2 are respectively hinged at the two ends of the hinge shaft.

[0016] In the buffer connection structure of the side plate of the above-mentioned communication cabinet, the contact piece 2 includes a pressing piece 2, a transition piece and a hinged tube 2. The transition piece and the pressing piece 2 are arranged obliquely and the two ends of the transition piece are respectively fixedly connected to the inner end of the pressing piece 2 and the hinged tube 2.

[0017] In the buffer connection structure of the side plate in the above-mentioned communication cabinet, the angle between the second pressing plate and the transition plate is an obtuse angle.

[0018] In the buffer connection structure of the side plate in the above-mentioned communication cabinet, the torsion spring includes torsion spring 1 and torsion spring 2 which are sleeved on the hinge shaft. The above-mentioned torsion spring 1 is arranged between hinge tube 1 and the hinge shaft, and the above-mentioned torsion spring 2 is arranged between hinge tube 2 and the hinge shaft.

[0019] In the buffer connection structure of the side plate in the communication cabinet, the upper sides and lower sides of the connecting piece 1, the connecting piece 2 and the connecting tube 1 are all flush.

[0020] In the buffer connection structure of the side plate in the communication cabinet, a plurality of avoidance holes are evenly distributed on the side of the connecting tube along its length direction.

[0021] In the buffer connection structure of the side panels in the above-mentioned communication cabinet, the side panel 1 and the side panel 2 are both hollow panels.

[0022] In the buffer connection structure of the side panel in the above-mentioned communication cabinet, a positioning plate for positioning electronic components is fixedly connected to the inner side of the second side panel and the size of the positioning plate is smaller than the size of the second side panel. The above-mentioned connecting edge two is L-shaped, one end of the connecting edge two is fixedly connected to the inner edge of the second side panel, and the other end of the connecting edge two is fixedly connected to the inner edge of the positioning plate.

[0023] Compared with the prior art, the buffer connection structure of the side panels in the communication cabinet has elastic pre-tightening components on both sides of side panel one and elastic pre-tightening components on both sides of side panel two. Therefore, side panel one can be stably connected between the corresponding two adjacent baffle bars, and side panel two can be stably connected between the corresponding two adjacent baffle bars. Since the two opposite side panels one and the two opposite side panels two are stably positioned, it is ultimately ensured that a cabinet with a stable structure is formed after the four side panels are connected. Moreover, since the elastic pre-tightening component can achieve buffering, when vibration is generated in the cabinet, the elastic pre-tightening component can effectively buffer the vibration, reduce the impact of vibration on the communication equipment in the cabinet, and avoid excessive noise caused by vibration.

[0024] It can be seen that the side panel can not only be stably connected between two adjacent gear rods, but also can appropriately buffer vibrations. Its stability is not only relatively high, but also its structure is relatively compact. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] 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.

[0034] like Figure 1 As shown, the communication cabinet includes a cabinet body with a hollow interior and a square frame-shaped cross section, and the cabinet body includes four plate-shaped side panels, which are connected end to end to form the cabinet body with the square frame-shaped cross section.

[0035] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 As shown, the buffer connection structure of the side panel in the communication cabinet includes a connecting edge one, a connecting edge two 5, a baffle 3 and an elastic pre-tightening component, and the adjacent two side panels are side panel one 1 and side panel two 2 respectively. The inner side of the baffle 3 has a recessed positioning notch 3a along its length direction, and the side panel one 1 and the side panel two 2 are both embedded in the positioning notch 3a, the connecting edge one is located at the inner edge of the side panel one 1, the connecting edge two 5 is located at the inner edge of the side panel two 2, the connecting edge one and the connecting edge two 5 are both located at the positioning notch 3a, and the elastic pre-tightening component is located between the connecting edge one and the connecting edge two 5. Under the action of the elastic pre-tightening component, the inner edge of the side panel one 1 and the inner edge of the side panel two 2 can be stably and tightly connected at the positioning notch 3a.

[0036] The inner edge of side panel 1 and the inner edge of side panel 2 are adjacent and both are embedded in the positioning recess 3a of the blocking rod 3. The connecting edge 1 of the inner edge of side panel 1 and the connecting edge 2 5 of the inner edge of side panel 2 provide sufficient space for the elastic preload component to be set.

[0037] The communication cabinet has two side panels 1 and two side panels 2, wherein the two side panels 1 are arranged opposite to each other, and the two side panels 2 are arranged opposite to each other.

[0038] The connection between the side panel 1 and the side panel 2 is affected by the elastic pre-tightening component, which can make the side panel 1 and the side panel 2 have a tendency to move away from the blocking rod 3. That is, both sides of the side panel 1 have a corresponding elastic pre-tightening component, and both sides of the side panel 2 have a corresponding elastic pre-tightening component. Therefore, under the action of multiple pre-tightening components, the side panel 1 is stably positioned between the corresponding two blocking rods 3, and the side panel 2 is stably positioned between the corresponding two blocking rods 3. Finally, it is ensured that all the side panels 1 and the side panels 2 are stably connected between the corresponding two adjacent blocking rods 3.

[0039] Of course, what is meant here is that the inner edge of side panel one and the inner edge of side panel two can be stably and tightly connected at the positioning recess, which does not mean that the inner edge of side panel one and the inner edge of side panel two have a tendency to move into the positioning recess, and the elastic force of the elastic preload component acts on both sides of side panel one, and the elastic force of the elastic preload component acts on both sides of side panel two.

[0040] The cross section of the blocking rod 3 is L-shaped. The side plate 1 is in contact with one inner side surface of the blocking rod 3 , and the side plate 2 is in contact with the other inner side surface of the blocking rod 3 .

[0041] Such a structure enables the inner side of the side plate 1 and the inner side of the side plate 2 2 to be stably connected to the positioning notch 3 a of the blocking rod 3 .

[0042] The connecting edge 1 is a connecting tube 4 which is fixedly connected to the edge of the side plate 1 and is in a cylindrical shape. The connecting edge 2 5 is in a plate shape and protrudes from the inner side of the side plate 2 2. One end of the elastic preload component is connected to the connecting tube 4, and the other end of the elastic preload component is in contact with the surface of the connecting edge 2 5.

[0043] The connecting tube 4 is fixedly connected to the inner edge of the side plate 1, and the cross section of the connecting tube 4 is in the shape of a square tube. The inner cavity of the connecting tube 4 can provide enough space for one end of the elastic preload component to be connected, and at the same time, the other end of the elastic preload component is in contact with the connecting edge 2 5, so that the elastic preload component can be stably connected between the connecting edge 1 and the connecting edge 2 5.

[0044] The elastic preload assembly includes a contact piece 1 6, a contact piece 2 7, a hinge shaft 8 and a torsion spring. The hinge shaft 8, the contact piece 2 7 and the inner ends of the contact piece 1 6 are all located in the connecting tube 4. The inner ends of the contact piece 1 6 and the inner ends of the contact piece 2 7 are both hinged on the hinge shaft 8. The torsion spring acts on the contact piece 1 6 and the contact piece 2 7. Under the elastic force of the torsion spring, the outer end of the contact piece 2 7 tends to rest against the connecting tube 4, and the outer end of the contact piece 1 6 tends to rest against the connecting edge 2 5.

[0045] Under the action of the torsion spring, both the contact piece 1 6 and the contact piece 2 7 have a tendency to swing around their hinges, and the swinging direction of the contact piece 1 6 is opposite to the swinging direction of the contact piece 2 7. Such a structure can ultimately make both the side panel 1 1 and the side panel 2 2 have a tendency to move away from the baffle rod 3, thereby ultimately ensuring that the side panel 1 is stably positioned between the corresponding two baffle rods 3, and the side panel 2 2 is stably positioned between the corresponding two baffle rods 3.

[0046] The contact piece 6 includes a pressing piece 6a, a connecting piece 6b, a connecting piece 6c and an articulated tube 6d. The pressing piece 6a is rectangular, the connecting piece 6b and the connecting piece 6c are both long sheets, the connecting piece 6c is arranged parallel to the pressing piece 6a, the two ends of the connecting piece 6b are respectively fixedly connected to the inner end of the pressing piece 6a and the inner end of the connecting piece 6c, the articulated tube 6d is fixedly connected to the outer end of the connecting piece 6c and the articulated tube 6d is sleeved on the articulated shaft 8, the side of the connecting tube 4 has a through avoidance hole 4a, and the connecting piece 6b is penetrated at the avoidance hole 4a.

[0047] The pressing plate 1 6a, the connecting plate 1 6b, the connecting plate 2 6c and the hinge tube 1 6d are an integrated structure.

[0048] The length of the hinge shaft 8 is greater than that of the hinge tube 6d and the hinge tube 6d is located in the middle of the hinge shaft 8. There are two contact pieces 7, which are hinged at both ends of the hinge shaft 8 respectively.

[0049] The contact piece 7 comprises a pressing piece 7a, a transition piece 7b and a hinged tube 7c. The transition piece 7b is tilted with the pressing piece 7a and two ends of the transition piece 7b are respectively fixedly connected to the inner end of the pressing piece 7a and the hinged tube 7c.

[0050] The included angle between the second pressing plate 7a and the transition plate 7b is an obtuse angle.

[0051] The torsion spring includes a torsion spring 1 9 and a torsion spring 2 10 which are sleeved on the hinge shaft 8 . The torsion spring 1 9 is arranged between the hinge tube 1 6 d and the hinge shaft 8 , and the torsion spring 2 10 is arranged between the hinge tube 2 7 c and the hinge shaft 8 .

[0052] The hinge tube 1 6d of the contact piece 1 6 is sleeved in the middle of the hinge shaft 8. Such a structure enables the inner end of the contact piece 1 6 to be stably hinged on the hinge shaft 8. The hinge tubes 2 7c of the two contact pieces 2 7 are sleeved at both ends of the hinge shaft 8 respectively.

[0053] The above structure enables one hinge cylinder 1 6d and two hinge cylinders 2 7c to be stably arranged along the length direction of the hinge shaft 8, and the hinge cylinder 1 6d is located between the two hinge cylinders 2 7c.

[0054] The connecting piece 6 b is passed through the avoidance hole 4 a of the connecting tube 4 . Such a structure enables the outer end of the contact piece 6 to stably extend out of the connecting tube 4 , that is, the pressing piece 6 a is stably located outside the connecting tube 4 .

[0055] Under the elastic force of torsion spring 1 9, contact piece 1 6 has a tendency to swing around its hinge, and under the elastic force of torsion spring 2 10, contact piece 2 7 has a tendency to swing around its hinge. And the swing directions of contact piece 1 6 and contact piece 2 7 are opposite.

[0056] The upper sides and lower sides of the connecting piece 1 6b, the connecting piece 2 6c and the connecting tube 1 6d are all flush.

[0057] Such a structure enables the inner end of the contact piece 6 to be conveniently connected to the connecting tube 4 through the avoidance hole 4a.

[0058] The side of the connecting tube 4 is uniformly provided with a plurality of avoidance holes 4a along its length direction.

[0059] The provision of a plurality of avoidance holes 4a enables the contact piece 6 to be connected to different height positions in the connecting tube 4, thereby improving its applicability.

[0060] The side panel 1 and the side panel 2 are both hollow panels.

[0061] The side panels 1 and 2 of the hollow slab can reduce material consumption while ensuring that the hollow slab has sufficient strength. At the same time, the side panels 1 and 2 of the hollow slab have a proper noise reduction effect.

[0062] A positioning plate 11 for positioning electronic components is fixedly connected to the inner side of the side panel 2, and the size of the positioning plate 11 is smaller than that of the side panel 2. The connecting edge 5 is L-shaped, and one end of the connecting edge 5 is fixedly connected to the inner edge of the side panel 2, and the other end of the connecting edge 5 is fixedly connected to the inner edge of the positioning plate 11.

[0063] The elastic force applied by the second torsion spring 10 can make the second connecting edge 5 stably lean against the second side plate 2 and the positioning plate 11, thereby preventing the second connecting edge 5 from being locally stressed and further improving its stability.

[0064] The buffer connection structure of the side panels in the communication cabinet has elastic pre-tightening components on both sides of side panel one and elastic pre-tightening components on both sides of side panel two. Therefore, side panel one can be stably connected between the corresponding two adjacent baffle bars, and side panel two can be stably connected between the corresponding two adjacent baffle bars. Since the two opposite side panels one and the two opposite side panels two are stably positioned, it is ultimately ensured that a structurally stable cabinet is formed after the four side panels are connected. Moreover, since the elastic pre-tightening components can achieve buffering, when vibration is generated in the cabinet, the elastic pre-tightening components can effectively buffer the vibration, reduce the impact of vibration on the communication equipment in the cabinet, and avoid excessive noise caused by vibration.

[0065] It can be seen that the side panel can not only be stably connected between two adjacent gear rods, but also can appropriately buffer vibrations. Its stability is not only relatively high, but also its structure is relatively compact.

[0066] The contact piece 1 is made of a rigid material, and the contact piece 2 is made of an elastic metal material. This ensures that the outer ends of the contact piece 1 and the outer ends of the contact piece 2 can both achieve surface contact. The surface contact connection method can improve the overall connection stability.

[0067] In this embodiment, the first contact piece is made of an aluminum alloy material with relatively high strength, and the second contact piece is made of a brass material, that is, the second contact piece is formed by bending a brass sheet.

[0068] 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.

[0069] 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.
