Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit installation technology, and specifically discloses a fixed support frame for installing a refrigeration air conditioner outdoor unit. Background Technology

[0002] The outdoor unit of an air conditioner is an important component of an air conditioning system. It is usually installed outdoors and exchanges heat with the indoor unit to achieve a comfortable indoor temperature. The outdoor unit generally consists of a compressor, condenser, evaporator, and control system. During the installation of an air conditioner, a support frame is usually installed under the outdoor unit to facilitate its installation and fixation outdoors.

[0003] Chinese patent CN215983199U discloses a support frame for installing an outdoor unit of an air conditioner, including a support platform. A support plate is provided at the bottom of the support platform. A limiting component is provided on the support platform, the limiting component including a movable plate and a bidirectional threaded rod. Two movable blocks are provided on the bidirectional threaded rod, and a movable plate is fixedly connected to the top of each movable block. A groove is formed on one side of the front of the support platform, and an electric telescopic rod is provided inside the groove. A telescopic plate is provided at the output end of the electric telescopic rod. A fixed plate is provided on the top of the support platform, and a sliding groove is formed on the front of the fixed plate. A matching sliding block is provided inside the sliding groove, and a positioning plate is fixedly connected to one side of the sliding block. A lifting cylinder is provided on the fixed plate. This utility model effectively fixes and protects air conditioner outdoor units of different sizes, extending their service life and ensuring the stability of the support frame installation. However, the aforementioned support frame lacks a protective and limiting structure for the bidirectional threaded rod during use. This causes the bidirectional threaded rod to loosen easily due to vibrations or wind from the air conditioner outdoor unit, affecting the clamping effect of the moving plate on the air conditioner outdoor unit. Furthermore, if the electric telescopic rod and lifting cylinder exposed outdoors in the aforementioned support frame malfunction, the telescopic rod and positioning plate will loosen, further affecting the fixing quality of the air conditioner outdoor unit. Therefore, to solve the above problems, this utility model proposes a fixed support frame for installing refrigeration air conditioner outdoor units. Utility Model Content

[0004] The present invention aims to provide a fixed support frame for installing an outdoor unit of a refrigeration air conditioner, which can keep the bidirectional lead screw stable during use, prevent the bidirectional lead screw from loosening, ensure the clamping effect of the two first clamps on the outdoor unit of the air conditioner, and prevent the bidirectional lead screw, telescopic rod and two types of unidirectional lead screws from being exposed to the outdoors, thereby extending the service life of the above components. The component with pressure plate auxiliary support can maintain the fixing quality of the pressure plate on the outdoor unit of the air conditioner even if the telescopic rod fails, thus ensuring the use effect of the fixed support frame.

[0005] This utility model is achieved through the following technical solution:

[0006] A fixed support frame for installing an outdoor unit of a refrigeration air conditioner includes a support structure and a clamping mechanism. The clamping mechanism is located above the support structure, and a pressing mechanism is located above the clamping mechanism. A protective structure is located below the support structure. The clamping mechanism includes two first clamping plates, each with a first protrusion connected to its lower side. A bidirectional lead screw is simultaneously threaded through the interior of each of the two first protrusions. A second clamping plate is located on one side of each of the first clamping plates, and a first protective shell is located on the side of each first clamping plate away from the second clamping plate. A second protrusion is connected to one end of each second clamping plate, and a first unidirectional lead screw is threaded through the interior of the second protrusion. The pressing mechanism includes a pressure plate, with multiple telescopic rods arranged in a linear array connected above the pressure plate. Support columns are located at the four corners of the pressure plate, and second unidirectional lead screws are located on the inner side of each support column. A retractable protective cover is located above the pressure plate. The protective structure includes two support plates, with a second protective shell detachably connected to the side of the two support plates that are close to each other.

[0007] As a further feature of the above solution, the support structure includes a bearing plate, one side of which is connected to a back plate to prevent the back of the air conditioner outdoor unit from contacting the wall. The upper end of the back plate near the bearing plate is connected to a top plate for easy installation of the clamping mechanism. The upper ends of both support plates are detachably connected to the bearing plate for easy disassembly and assembly. A first through hole is provided in the middle of the bearing plate, and the first protrusion passes through the interior of the first through hole and is slidably connected to the first through hole, which can initially restrict the movement direction of the two first clamping plates.

[0008] As a further provision of the above solution, a first limiting plate is provided on both sides of the first protrusion. Both first limiting plates are connected to the bearing plate to facilitate the installation and maintenance of the first limiting plates. A first limiting hole is provided inside the first limiting plate. A first limiting rod is connected to both sides of the first protrusion. The first limiting rod passes through the inside of the first limiting hole and is slidably connected to the first limiting hole, which can further restrict the movement direction of the two first clamping plates. The first protrusion is threadedly connected to a bidirectional lead screw, which can ensure that the bidirectional lead screw can simultaneously drive the two first protrusions and the components above them to move during rotation. One end of the bidirectional lead screw is rotatably connected to a... The first support base facilitates the rotation of the bidirectional lead screw. A first handwheel is connected to the end of the bidirectional lead screw away from the first support base. The first handwheel has multiple first insertion holes arranged in a circumferential array inside. A second insertion rod is connected to the side of the support plate near the bearing plate. The second insertion rod is inserted into the first insertion holes, which can fix the bidirectional lead screw after it stops rotating, preventing it from loosening. The first limiting plate, the first limiting rod, the bidirectional lead screw, and the first handwheel are all located inside the second protective shell, which can protect the above components during the use of the support frame, protect the above components from weather factors, and extend the service life of the above components.

[0009] As a further provision of the above solution, a second through hole is provided at one end of the first clamping plate, and the second protrusion passes through the interior of the second through hole and is slidably connected to the second through hole, which can initially restrict the movement direction of the second clamping plate. A second limiting plate is provided on both sides of the second protrusion, and both second limiting plates are connected to the first clamping plate. A second limiting hole is provided inside the second limiting plate, and a second limiting rod is connected to both sides of the second protrusion. The second limiting rod passes through the interior of the second limiting hole and is slidably connected to the second limiting hole, which can further restrict the movement direction of the second clamping plate, so that the second clamping plate remains stable during the process of clamping the air conditioner from the side of the air conditioner outdoor unit away from the back panel.

[0010] As a further feature of the above solution, the first one-way lead screw is threadedly connected to the second protrusion, and a second support seat is rotatably connected to one end of the first one-way lead screw, which helps the second protrusion and the second clamping plate to move during the rotation of the first one-way lead screw. A second handwheel is connected to the end of the first one-way lead screw away from the second support seat. The interior of the second handwheel is provided with a plurality of second insertion holes arranged in a circumferential array. A first insertion rod is connected to the side of the first protective shell near the second handwheel. The first insertion rod is inserted into the second insertion hole, which can fix the first one-way lead screw after it stops rotating, so that the first one-way lead screw remains stable during the clamping and fixing of the air conditioner outdoor unit by the second clamping plate. A baffle is connected to one side of the first clamping plate. The two ends of the first protective shell are detachably connected to the baffle and the first clamping plate, respectively, which can protect the second limiting plate, the second limiting rod, the first one-way lead screw, and the handwheel, and extend the service life of the above components.

[0011] As a further feature of the above solution, the ends of the support column and the telescopic rod furthest from the pressure plate are both connected to the top plate, facilitating the installation and maintenance of the components. The inner side of the support column is provided with an internal threaded groove, which is threadedly connected to a second one-way screw. The lower end of the second one-way screw is connected to a stop plate, which is detachably connected to the pressure plate. When the telescopic rod stops extending or retracting, the distance between the stop plate and the support column can be adjusted by rotating the second one-way screw to adjust the depth of the second one-way screw embedded in the internal threaded groove, thereby adjusting the overall length of the combination of the stop plate, the second one-way screw, and the support column. This allows the components to restrict the position of the pressure plate from the four corners above it. The upper and lower ends of the retractable protective cover are detachably connected to the top plate and the pressure plate, respectively, protecting the telescopic rod, support column, and second one-way screw inside the retractable protective cover and extending their service life.

[0012] In this utility model, the lower end of the back plate and the side of the two support plates that are far apart from each other are provided with multiple mounting holes for installing support frames. In order to prevent dust and rain and snow from falling into the inner side of the second protective shell through the first through hole, an additional dust plug or dust plate can be added to the part of the first through hole that is far away from the air conditioner outdoor unit during the installation of the air conditioner outdoor unit.

[0013] The present invention has the following beneficial effects during use:

[0014] The combination of the second clamping plate, the first one-way screw, and the two second limiting plates allows the second clamping plate to move smoothly by rotating the first one-way screw, clamping and fixing the outdoor unit from the side away from the back panel, thus further stabilizing the outdoor unit. The combination of multiple second insertion holes inside the second handwheel and the first insertion rod at one end of the first protective shell can fix the second handwheel and the first one-way screw after the second clamping plate stops moving and the first one-way screw stops rotating, ensuring the clamping effect of the second clamping plate on the outdoor unit.

[0015] The use of the first and second protective shells can protect the components such as the bidirectional lead screw and the unidirectional lead screw in the clamping mechanism, and extend the service life of the components inside the two protective shells. The use of multiple first insertion holes in the first handwheel can ensure that after the bidirectional lead screw stops rotating, the second insertion rod on one side of the support plate can always be inserted into the appropriate first insertion hole during the installation process, so as to limit the position of the first handwheel and the bidirectional lead screw.

[0016] The combination of multiple support columns, a second one-way screw, and a stop plate in the clamping mechanism can further restrict the position of the pressure plate after the telescopic rod stops extending and retracting, keeping the pressure plate stable and preventing it from loosening when the telescopic rod malfunctions. The use of the telescopic protective cover can protect the telescopic rod, support columns, and second one-way screw inside the telescopic protective cover after the air conditioner outdoor unit is installed, extending the service life of these components.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-8 This application will be described in detail with reference to the embodiments.

[0029] An embodiment discloses a fixing support frame for installing an outdoor unit of a refrigeration air conditioner, including a support structure 1 and a clamping mechanism 2. The clamping mechanism 2 is arranged above the support structure 1, and a pressing mechanism 3 is arranged above the clamping mechanism 2. A protective structure 4 is arranged below the support structure 1. The clamping mechanism 2 includes two first clamping plates 21, and a first protrusion 211 is connected to the lower part of each of the two first clamping plates 21. A bidirectional lead screw 23 is simultaneously arranged through the interior of the two first protrusions 211. A second clamping plate 24 is arranged on one side of the first clamping plate 21, and a second clamping plate 24 is arranged on the side of the first clamping plate 21 away from the second clamping plate 24. A protective shell 28 is provided. One end of the second clamping plate 24 is connected to a second protrusion 241. A first one-way screw 26 is provided through the interior of the second protrusion 241. The pressing mechanism 3 includes a pressure plate 31. Multiple telescopic rods 32 arranged in a linear array are connected above the pressure plate 31. Support columns 33 are provided at the four corners above the pressure plate 31. A second one-way screw 34 is provided on the inner side of the support column 33. A retractable protective cover 36 is provided above the pressure plate 31. The protective structure 4 includes two support plates 41. The second protective shell 42 is detachably connected to the side of the two support plates 41 that is close to each other.

[0030] like Figure 1 and Figure 2 As shown, the support structure 1 includes a bearing plate 11. A back plate 12 is connected to one side of the bearing plate 11 to prevent the back of the air conditioner outdoor unit from contacting the wall. A top plate 13 is connected to the upper end of the back plate 12 near the bearing plate 11 to facilitate the installation of the clamping mechanism 3. The upper ends of the two support plates 41 are detachably connected to the bearing plate 11 to facilitate the disassembly and assembly of the support plates 41. A first through hole 111 is provided in the middle of the bearing plate 11. The first protrusion 211 passes through the interior of the first through hole 111 and is slidably connected to the first through hole 111, which can initially restrict the movement direction of the two first clamping plates 21.

[0031] like Figure 2 and Figure 3As shown, both sides of the first protrusion 211 are provided with first limiting plates 22, and both first limiting plates 22 are connected to the bearing plate 11 to facilitate the installation and maintenance of the first limiting plates 22. The first limiting plate 22 is provided with a first limiting hole 221 inside. Both sides of the first protrusion 211 are connected with first limiting rods 213. The first limiting rods 213 pass through the inside of the first limiting hole 221 and are slidably connected to the first limiting hole 221, which can further restrict the movement direction of the two first clamping plates 21. The first protrusion 211 is threadedly connected to the bidirectional lead screw 23, which can ensure that the bidirectional lead screw 23 drives the two first protrusions 211 and the components above them to move simultaneously during the rotation of the bidirectional lead screw 23. One end of the bidirectional lead screw 23 is rotatably connected to a first support seat 2. 31. To facilitate the rotation of the bidirectional lead screw 23, a first handwheel 232 is connected to the end of the bidirectional lead screw 23 away from the first support base 231. The first handwheel 232 has a plurality of first insertion holes 233 arranged in a circumferential array inside. A second insertion rod 43 is connected to the side of the support plate 41 near the bearing plate 11. The second insertion rod 43 is inserted into the first insertion hole 233, which can fix the bidirectional lead screw 23 after it stops rotating, preventing the bidirectional lead screw 23 from loosening. The first limiting plate 22, the first limiting rod 213, the bidirectional lead screw 23 and the first handwheel 232 are all located inside the second protective shell 42, which can protect the above components during the use of the support frame, protect the above components from the influence of weather factors and extend the service life of the above components.

[0032] like Figure 3 and Figure 4 As shown, a second through hole 212 is provided at one end of the first clamping plate 21. The second protrusion 241 passes through the second through hole 212 and is slidably connected to the second through hole 212, which can initially restrict the movement direction of the second clamping plate 24. A second limiting plate 25 is provided on both sides of the second protrusion 241. Both second limiting plates 25 are connected to the first clamping plate 21. A second limiting hole 251 is provided inside the second limiting plate 25. A second limiting rod 242 is connected to both sides of the second protrusion 241. The second limiting rod 242 passes through the second limiting hole 251 and is slidably connected to the second limiting hole 251, which can further restrict the movement direction of the second clamping plate 24, so that the second clamping plate 24 can remain stable during the process of clamping the air conditioner from the side away from the back plate 12 of the air conditioner outdoor unit.

[0033] like Figure 4 and Figure 5As shown, the first one-way lead screw 26 is threadedly connected to the second protrusion 241. One end of the first one-way lead screw 26 is rotatably connected to the second support base 261, which helps the second protrusion 241 and the second clamping plate 24 to move during the rotation of the first one-way lead screw 26. The end of the first one-way lead screw 26 away from the second support base 261 is connected to the second handwheel 262. The interior of the second handwheel 262 is provided with a plurality of second insertion holes 263 arranged in a circumferential array. The side of the first protective shell 28 near the second handwheel 262 is connected to the first insertion rod 28. 1. The first insertion rod 281 is inserted into the second insertion hole 263, which can fix the first one-way screw 26 after it stops rotating, so that the first one-way screw 26 remains stable during the clamping and fixing of the air conditioner outdoor unit by the second clamping plate 24. A baffle 27 is connected to one side of the first clamping plate 21. The two ends of the first protective shell 28 are detachably connected to the baffle 27 and the first clamping plate 21, respectively, which can protect the second limiting plate 25, the second limiting rod 242, the first one-way screw 26 and the handwheel and other components, and extend the service life of the above components.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, the ends of the support column 33 and the telescopic rod 32 away from the pressure plate 31 are both connected to the top plate 13, facilitating the installation and maintenance of these components. The inner side of the support column 33 is provided with an internal threaded groove 331, which is threadedly connected to the second one-way screw 34. The lower end of the second one-way screw 34 is connected to a stop plate 35, which is detachably connected to the pressure plate 31. This allows the second one-way screw 34 to be adjusted by rotating it when the telescopic rod 32 stops extending or retracting. The depth adjustment in the threaded groove 331 adjusts the distance between the abutment 35 and the support column 33, thereby adjusting the overall length of the combination of the abutment 35, the second one-way screw 34 and the support column 33, so that the above components restrict the position of the pressure plate 31 from the four corners above the pressure plate 31. The upper and lower ends of the telescopic protective cover 36 are detachably connected to the top plate 13 and the pressure plate 31, respectively, which can protect the telescopic rod 32, the support column 33 and the second one-way screw 34 and other components inside the telescopic protective cover 36, and extend the service life of the above components.

[0035] The fixed support bracket for installing an outdoor unit of a refrigeration air conditioner disclosed in this embodiment, before use, involves passing screws or other existing mounting components through the mounting holes below the back plate 12, fixing the back plate 12 together with the support structure 1 to the wall, removing the retractable protective cover 36, placing the outdoor unit of the air conditioner on the support plate 11, holding the first handwheel 232 and rotating the double-acting screw 23, simultaneously moving the two first clamping plates 21 to both sides of the outdoor unit of the air conditioner. After the opposite sides of the two first clamping plates 21 are tightly fitted to both sides of the outdoor unit of the air conditioner, stop rotating the double-acting screw 23, install the support plate 41 without the second insert 43 at the end of the support plate 11 away from the first handwheel 232, and then install the second protective cover 42... One end is connected to the support plate 41. Another support plate 41 with a second insertion rod 43 is installed on the bearing plate 11 near the first handwheel 232. The support plate 41 is connected to the other end of the second protective shell 42. The second insertion rod 43 is inserted into the appropriate first insertion hole 233. The bidirectional screw 23 is fixed. The two first one-way screws 26 are rotated in sequence to move the two second clamping plates 24 toward the air conditioner outdoor unit. After the side of the second clamping plate 24 near the air conditioner outdoor unit is tightly attached to the air conditioner outdoor unit, the two ends of the first protective shell 28 are connected to the baffle 27 and the first clamping plate 21 respectively. The first insertion rod 281 is inserted into the appropriate second insertion hole 263. The first one-way screw 26 and the second clamping plate 24 are fixed.

[0036] Disconnect the four support plates 35 and pressure plates 31 in sequence. Connect the input end of the telescopic rod 32 to the power supply and control the telescopic rod 32 to extend, driving the pressure plate 31 to move towards the top surface of the air conditioner outdoor unit. After the pressure plate 31 is tightly attached to the top surface of the air conditioner outdoor unit, close the telescopic rod 32. Rotate the four second internal thread rods in sequence to adjust the distance between the support plates 35 and pressure plates 31. When the support plates 35 and pressure plates 31 are in contact, connect and install the support plates 35 and pressure plates 31 together to restrict the position of the pressure plates 31. Reset the telescopic protective cover 36 and restore the connection between the two ends of the telescopic protective cover 36 and the top plate 13 and pressure plate 31 respectively. The air conditioner outdoor unit is now installed and fixed.
