Description

Technical Field

[0001] The present application belongs to the technical field of air conditioning equipment installation, and specifically relates to an installation structure of a ceiling unit and a ceiling unit. Background Art

[0002] A ceiling unit is a form of central air-conditioning system. The characteristic of a ceiling unit is that it is installed in a ceiling-mounted manner, hidden inside the ceiling, leaving only the air outlet exposed to the outside, which can save space and improve the aesthetics of the building.

[0003] In the related art, when installing the ceiling machine, the operator needs to first fix the threaded rods to the four corners of the ceiling machine, then connect the ceiling machine with the pipes in the ceiling, and finally connect the threaded rods to the ceiling.

[0004] However, during the installation of existing ceiling machines, operators are required to hold up the ceiling machine for a long time, which causes discomfort to the operators, makes installation and adjustment inconvenient, and even causes the risk of the ceiling machine falling during installation. Utility Model Content

[0005] The present application provides a ceiling machine installation structure and a ceiling machine, which eliminates the need for an operator to hold the ceiling machine for a long time during installation, thereby facilitating installation and adjustment by the operator and improving safety.

[0006] The technical solutions adopted in this application are as follows:

[0007] In a first aspect, an embodiment of the present application provides a mounting structure of a ceiling unit, which is used to connect the ceiling unit to a ceiling, and includes at least one bracket assembly and at least one connecting member;

[0008] The bracket assembly includes a first bracket and a second bracket, the first bracket is used to be connected to the ceiling, and the second bracket is used to be connected to the side panel of the ceiling unit;

[0009] The first bracket has a guide rail, and the bottom wall of the guide rail has at least two positioning grooves, and the positioning grooves are arranged at intervals along the length direction of the guide rail;

[0010] The connecting member is arranged on the second bracket, inserted into the guide rail, and rolls in the guide rail, so that part of the connecting member can be snapped into one of the positioning grooves.

[0011] By adopting the above technical solution, when installing the ceiling machine, the operator first connects the first bracket to the preset position of the ceiling, then connects the second bracket to the side panel of the ceiling machine, and then inserts the connecting piece into the guide rail of the first bracket, and at the same time makes the connecting piece snap into one of the positioning grooves. At this time, it is equivalent to hanging the ceiling machine on the first bracket through the second bracket and the connecting piece, freeing the operator's hands and facilitating the operator to install the pipeline. Finally, the ceiling machine is pushed to make the connecting piece snap into another positioning groove, which is equivalent to installing the ceiling machine to the preset position. This process does not require the operator to hold the ceiling machine for a long time, which is convenient for the operator to install and adjust, and improves safety.

[0012] In a possible implementation, an embodiment of the present application provides a mounting structure for a ceiling unit, wherein the number of the positioning grooves is at least three, and the positioning grooves are arranged at equal distances;

[0013] The number of the connecting members is at least two, and each of the connecting members is correspondingly snapped into the positioning groove.

[0014] By adopting the above technical solution, the number of connecting parts is set to at least two, and the number of positioning grooves is set to at least three, so that the two connecting parts can be respectively and simultaneously connected to the two adjacent positioning grooves. It can be understood here that it is equivalent to providing more force support points, dispersing the pressure on a single connecting part, and extending the service life of the connecting part. At the same time, more support points can improve the stability of the structure.

[0015] In a possible implementation, an embodiment of the present application provides a mounting structure for a ceiling unit, wherein the connecting member includes a connecting column and a rolling bearing;

[0016] The second bracket is connected to the rolling bearing via the connecting column. The rolling bearing is located in the guide rail and rolls along the extending direction of the guide rail.

[0017] By adopting the above technical solution, the rolling bearing can achieve rolling in the guide rail. The use of the rolling bearing can reduce the friction resistance of the connecting part in the guide rail, thereby making the second bracket move more smoothly relative to the first bracket, reducing energy loss and improving the movement efficiency of the structure.

[0018] In addition, the rolling bearing has a good load capacity, can support ceiling machines of various weights, and improve the adaptability of the connecting parts. And the connection column and the rolling bearing are connected, the structure is simple and the cost is low.

[0019] In a possible implementation, an embodiment of the present application provides a mounting structure for a ceiling unit, wherein the length of the positioning groove is smaller than the outer diameter of the rolling bearing.

[0020] By adopting the above technical solution, it can be understood that the length of the positioning groove is smaller than the outer diameter of the rolling bearing, so that part of the rolling bearing can be snapped into the positioning groove without passing through the positioning groove, thereby preventing the rolling bearing from falling out.

[0021] Here, it can be understood that, since the rolling bearing cannot completely pass through the positioning groove, there is no need to worry about over-adjustment of the rolling bearing during assembly, which simplifies the assembly steps.

[0022] In a possible implementation, an embodiment of the present application provides a mounting structure for a ceiling unit, further comprising at least one lifting member;

[0023] The lifting member is configured to connect the second bracket and the first bracket, and drive the second bracket to move toward or away from the first bracket.

[0024] By adopting the above technical solution, when the ceiling machine is moved to the preset position, the second bracket is connected to the first bracket through the lifting member, which can then play the role of fixing the first bracket and the second bracket. By operating the lifting member, the second bracket is driven to move closer to the first bracket, and the second bracket drives the ceiling machine to move, which is equivalent to making the ceiling machine closer to the ceiling, which helps to improve the overall aesthetics of the ceiling machine after installation, and at the same time improves the stability of the ceiling machine.

[0025] Operating the lifting member to drive the second bracket to move away from the first bracket can facilitate the operator to repair the ceiling machine. By setting the lifting member, the connection between the first bracket and the second bracket can be strengthened while facilitating the disassembly and assembly of the ceiling machine.

[0026] In a possible implementation, an embodiment of the present application provides a mounting structure for a ceiling unit, wherein the first bracket includes a top plate, a first side plate, and a first bottom plate connected in sequence;

[0027] The top plate is used to be connected to the ceiling, and the positioning groove is located on the first bottom plate;

[0028] The second bracket includes a second side plate and a second bottom plate, the second side plate is connected to the second bottom plate, the second side plate is used to be connected to the side plate of the ceiling unit, and the second bottom plate is connected to the first bottom plate through the lifting member.

[0029] By adopting the above technical solution, the top plate, the first side plate and the first bottom plate are connected in sequence to achieve connection between the top plate and the ceiling. The first bottom plate is connected to the second bottom plate through a lifting member, which has a compact structure and does not interfere with each other, and can improve the stability of the structure.

[0030] In a possible implementation, an embodiment of the present application provides a mounting structure for a ceiling unit, wherein the first bottom plate has a flange along its length direction, and the flange, the first bottom plate and the first side plate are together arranged to form the guide rail.

[0031] By adopting the above technical solution, the flange, the first bottom plate and the first side plate are jointly arranged to form a guide rail, without the need to add other structures, thereby simplifying the structure. The flange design makes it difficult for the connecting piece to fall off the guide rail, thereby improving the reliability and stability of the connecting piece's movement.

[0032] In a possible implementation, an embodiment of the present application provides a mounting structure for a ceiling unit, further comprising at least one expansion bolt, wherein the top plate is used to be connected to the ceiling via the expansion bolt, and the expansion bolts are arranged at intervals along the length direction of the top plate.

[0033] By adopting the above technical solution, the expansion bolts can be applied to a variety of different ceiling materials, thereby improving the applicability of the connection between the first bracket and the ceiling. In addition, the expansion bolts can be disassembled relatively easily, facilitating the subsequent disassembly and assembly process.

[0034] In a possible implementation, an embodiment of the present application provides a mounting structure for a ceiling unit, wherein the first bracket further includes a dustproof plate, and the dustproof plate is connected to a side of the top plate facing away from the side plate.

[0035] By adopting the above technical solution, the ceiling machine usually does not need to be adjusted for a long time after installation. Dust and other floating objects in the environment will fall onto the surface of the connecting parts or guide rails due to gravity and affect the movement of the structure. By providing a dustproof plate, dust can be reduced from falling onto the surface of the connecting parts or guide rails, thereby keeping the structure clean and tidy and improving the reliability of movement.

[0036] In a second aspect, an embodiment of the present application provides a ceiling machine, comprising a ceiling machine body and a mounting structure of the ceiling machine, wherein the ceiling machine body is connected to the ceiling via the mounting structure of the ceiling machine.

[0037] By adopting the above technical solution, when installing a ceiling machine provided with the above ceiling machine installation structure, an operator does not need to hold up the ceiling machine for a long time, which can facilitate installation and adjustment by the operator and improve safety.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0060] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0062] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0063] As mentioned in the background technology, the ceiling machine in the prior art has the problem of complicated installation and adjustment process, causing discomfort to the operator, and there is a risk of falling during installation. The reason for the above problems is that when installing the ceiling machine on the ceiling in the prior art, it is first necessary to fix the threaded rods to the four corners of the ceiling machine, then lift the ceiling machine close to the ceiling, then connect the pipes in the ceiling machine with the pipes in the ceiling, and finally connect the threaded rods to the ceiling. During this process, the operator needs to lift the ceiling machine for a long time until the threaded rods are connected to the ceiling, which can easily cause discomfort to the operator and is inconvenient to install and adjust the ceiling machine. It may even require more than two operators to install a ceiling machine, and the installation efficiency is low.

[0064] Based on the above problems, the present application provides a ceiling machine installation structure and ceiling machine. In the technical solution, a first bracket is connected to the ceiling, and a second bracket is connected to the side panel of the ceiling machine. The first bracket has a guide rail, and the bottom wall of the guide rail has at least two positioning grooves. The first bracket is provided with a connecting piece, which is located in the guide rail and rolls and is snapped into one of the positioning grooves. The operator only needs to lift the ceiling machine once so that the connecting piece is inserted into the guide rail. The operator does not need to lift the ceiling machine for a long time for installation, which simplifies the installation and adjustment process, reduces the risk when installing the ceiling machine, and improves the installation efficiency.

[0065] It should be noted that Figure 1 and Figure 2 The installation structure of the ceiling machine and the simplified schematic diagram of the ceiling machine are shown. The installation structure of the ceiling machine and the specific structures of the other components of the ceiling machine are not limited to Figure 1 and Figure 2 of examples.

[0066] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0067] Reference Figure 1 and Figure 2 As shown, the present application provides a mounting structure of a ceiling machine, which is used to connect the ceiling machine to the ceiling. It should be noted that the mounting structure of the ceiling machine provided by the present application can be applied to various different ceiling machines, and the specific structure of the ceiling machine is not limited here.

[0068] The present application provides a mounting structure for a ceiling unit, which includes at least one bracket assembly and at least one connecting member 100 .

[0069] Correspondingly, bracket assemblies and connectors 100 are provided on opposite sides of the ceiling unit.

[0070] The bracket assembly includes a first bracket 200 and a second bracket 300. The first bracket 200 is used to connect to the ceiling, and the second bracket 300 is used to connect to the side panel of the ceiling machine. The second bracket 300 and the side panel of the ceiling machine can be connected by multiple bolts or screws, or can be welded. The connection structure of the second bracket 300 and the side panel of the ceiling machine is not limited here.

[0071] The first bracket 200 has a guide rail 201, the length direction of the guide rail 201 is arranged along the extension direction of the first bracket 200, and the bottom wall of the guide rail 201 has at least two positioning grooves 202, each positioning groove 202 is arranged at intervals along the length direction of the guide rail 201. In order to simplify the processing of the positioning groove 202, the positioning groove 202 is a through hole.

[0072] The connecting member 100 is disposed on the second bracket 300 . The connecting member 100 is inserted into the guide rail 201 and rolls in the guide rail 201 , so that a portion of the connecting member 100 can be snapped into one of the positioning grooves 202 .

[0073] When installing the ceiling machine, the operator first connects the first bracket 200 to the preset position of the ceiling, then connects the second bracket 300 to the side panel of the ceiling machine, and then inserts the connecting piece 100 into the guide rail 201 of the first bracket 200, and at the same time makes the connecting piece 100 snap into one of the positioning grooves 202. At this time, the ceiling machine is equivalent to being hung on the first bracket 200 through the second bracket 300 and the connecting piece 100, freeing the operator's hands and facilitating the operator to install the pipeline. Finally, the ceiling machine is pushed to make the connecting piece 100 snap into another positioning groove 202, which is equivalent to installing the ceiling machine to the preset position. This process does not require the operator to hold the ceiling machine for a long time, which facilitates the operator's installation and adjustment and improves safety.

[0074] In other possible implementations, continue to refer to Figure 1 and Figure 2 As shown, the number of the positioning grooves 202 is at least three, and the positioning grooves 202 are arranged at equal distances.

[0075] The number of the connecting members 100 is at least two, and each connecting member 100 is correspondingly snapped into the positioning groove 202 .

[0076] By setting the number of connecting members 100 to at least two and the number of positioning grooves 202 to at least three, two connecting members 100 can be respectively and simultaneously snapped into two adjacent positioning grooves 202. It can be understood here that this is equivalent to providing more force support points, dispersing the pressure on a single connecting member 100, and extending the service life of the connecting member 100. At the same time, more support points can improve the stability of the structure.

[0077] Of course, it should be noted that, if a connecting member 100 is provided on both sides of the ceiling machine, the ceiling machine may rotate relative to the first bracket 200 with the connecting member 100 as the rotation axis. At this time, the operator is required to hold the ceiling machine. At least two connecting members 100 are provided on both sides of the ceiling machine, which is equivalent to a limiter, restricting the rotation of the ceiling machine, thereby further improving the stability of the installation of the ceiling machine.

[0078] In other possible implementations, the connecting member 100 includes a connecting column 110 and a rolling bearing 120 .

[0079] The second bracket 300 is connected to the rolling bearing 120 via the connecting column 110 . The rolling bearing 120 is located in the guide rail 201 and rolls along the extending direction of the guide rail 201 .

[0080] It should be noted that the rolling bearing 120 is a related technology in this field, and the connection structure between the rolling bearing 120 and the connecting column 110 is not limited here.

[0081] The rolling bearing 120 can achieve rolling in the guide rail 201. The use of the rolling bearing 120 can reduce the friction resistance of the connecting member 100 in the guide rail 201, thereby making the second bracket 300 move more smoothly relative to the first bracket 200, reducing energy loss and improving the movement efficiency of the structure.

[0082] In addition, the rolling bearing 120 has a good load capacity and can support ceiling machines of various weights, thereby improving the adaptability of the connector 100. The connection between the connecting column 110 and the rolling bearing 120 has a simple structure and low cost. At the same time, the rolling bearing 120 has good wear resistance and can support the connector 100 to roll in the guide rail 201 multiple times.

[0083] In a specific implementation, in order to prevent the rolling bearing 120 from falling out, the length of the positioning groove 202 is smaller than the outer diameter of the rolling bearing 120 .

[0084] It is understandable that the length of the positioning groove 202 is smaller than the outer diameter of the rolling bearing 120 , so that part of the rolling bearing 120 can be snapped into the positioning groove 202 without passing through the positioning groove 202 , thereby preventing the rolling bearing 120 from falling out.

[0085] Here, it can be understood that, since the rolling bearing 120 cannot completely pass through the positioning groove 202 , there is no need to worry about over-adjustment of the rolling bearing 120 during assembly, thereby simplifying the assembly steps.

[0086] In a possible implementation, the installation structure of the ceiling unit also includes at least one lifting member 400, which is configured to connect the second bracket 300 and the first bracket 200 and drive the second bracket 300 to move toward or away from the first bracket 200.

[0087] Specifically, the lifting member 400 may be a fastening bolt, and mounting holes are correspondingly provided on the first bracket 200 and the second bracket 300. The number of the lifting members 400 may be selected according to the connection strength requirement, and the number of the lifting members 400 is not limited here.

[0088] When the ceiling unit is moved to a preset position, the second bracket 300 and the first bracket 200 are connected by the lifting member 400, so that the first bracket 200 and the second bracket 300 can be fixed.

[0089] Rotate the lifting member 400 to drive the second bracket 300 to move closer to the first bracket 200. The second bracket 300 drives the ceiling unit to move, which is equivalent to making the ceiling unit closer to the ceiling, which helps to improve the overall aesthetics of the ceiling unit after installation and improves the stability of the ceiling unit.

[0090] Rotating the lifting member 400 drives the second bracket 300 to move away from the first bracket 200, which can facilitate the operator to repair the ceiling machine. By setting the lifting member 400, the connection between the first bracket 200 and the second bracket 300 can be strengthened while facilitating the disassembly and assembly of the ceiling machine.

[0091] In a possible implementation, the first bracket 200 includes a top plate 210 , a first side plate 220 , and a first bottom plate 230 that are connected in sequence.

[0092] The top plate 210 is used to connect to the ceiling, and the positioning groove 202 is located on the first bottom plate 230 .

[0093] The second bracket 300 includes a second side plate 310 and a second bottom plate 320 . The second side plate 310 is connected to the second bottom plate 320 . The second side plate 310 is used to be connected to the side plate of the ceiling unit. The second bottom plate 320 is connected to the first bottom plate 230 via a lifting member 400 .

[0094] The top plate 210 is configured to be connected to the ceiling, providing a stable top support point, thereby ensuring that the first bracket 200 is stably connected to the ceiling. The first bottom plate 230 is connected to the second bottom plate 320 via a lifting member 400, having a compact structure and non-interference effects, and can improve the stability of the structure.

[0095] Specifically, the top plate 210 , the first side plate 220 and the first bottom plate 230 are integrally formed, and the integral forming can further improve the strength and rigidity of the first bracket 200 , and extend the service life of the first bracket 200 .

[0096] When implementing it, refer to Figure 2 As shown, the first bottom plate 230 has a flange 240 along its length, and the flange 240, the first bottom plate 230 and the first side plate 220 are together arranged to form a guide rail 201. The flange 240 and the first bottom plate 230 are integrally formed, and it should be noted that the material of the first bracket 200 is not limited.

[0097] The flange 240, the first bottom plate 230 and the first side plate 220 are together arranged to form the guide rail 201, and no other structures are required to be added, thereby simplifying the structure. The design of the flange 240 makes it difficult for the connector 100 to fall out of the guide rail 201, thereby improving the reliability and stability of the movement of the connector 100.

[0098] In order to improve the stability of the connection between the first bracket 200 and the ceiling, at least one expansion bolt 500 is further included. The top plate 210 is used to connect to the ceiling through the expansion bolt 500, and each expansion bolt 500 is arranged at intervals along the length direction of the top plate 210. The number of expansion bolts 500 can be selected as needed and is not limited here. The expansion bolt 500 can be applied to a variety of different ceiling materials, which improves the applicability of the connection between the first bracket 200 and the ceiling. In addition, the expansion bolt 500 can be easily disassembled, which is convenient for the subsequent disassembly and assembly process.

[0099] Continue to refer to Figure 1 and Figure 2 As shown, it can be understood that the ceiling unit usually does not need to be adjusted for a long time after installation. Dust and other floating objects in the environment will fall onto the surface of the connecting piece 100 or the guide rail 201 due to gravity, affecting the movement of the structure. For this reason, the first bracket 200 also includes a dustproof plate 250, which is connected to the side of the top panel 210 away from the side panel.

[0100] By providing the dustproof plate 250, dust can be reduced from falling onto the surface of the connector 100 or the guide rail 201, thereby keeping the structure clean and tidy and improving the reliability of movement.

[0101] The present application also provides a ceiling machine, including a ceiling machine body 600 and the above-mentioned ceiling machine installation structure. The ceiling machine body 600 is connected to the ceiling through the ceiling machine installation structure. The setting method and structure of the ceiling machine installation structure have been described above and will not be repeated here.

[0102] So far, the technical solution of the present application has been described in conjunction with the implementation methods shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific implementation methods. The above embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
