Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, and in particular to a foldable mounting bracket for the outdoor unit of a multi-split central air conditioning system. Background Technology

[0002] Outdoor unit mounting brackets typically consist of a support frame, fixing connectors, and possible reinforcing structures. Existing air conditioner brackets may occupy a large amount of space and are not easy to fold, leading to installation difficulties.

[0003] Chinese patent application CN202321228446.0 discloses an air conditioner outdoor unit mounting bracket. The key technical point of the bracket is that, by improving upon existing technology, a guide rail is provided inside the support bar, and the guide rail is slidably connected to a groove on the surface of the extension block. Before use, the length of the bottom support bar is adjusted according to the size of the air conditioner outdoor unit. By stretching the connecting block, the extension block moves through the groove on the surface of the guide rail and moves out inside the support bar. After moving to the appropriate position according to the size of the air conditioner outdoor unit, the extension block and the support bar are fixed together with bolts, thereby supporting air conditioner outdoor units of different sizes.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: existing air conditioner brackets may occupy a large space during installation and are not easy to fold, resulting in installation difficulties. Due to the relatively small standing space for external operations, it is difficult to place the large outdoor unit bracket, which leads to the problem that the workers need to hold the external bracket while performing the operation. Therefore, in order to solve the above problems, a foldable central air conditioning multi-split outdoor unit installation bracket is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing technology has the disadvantage that the large outdoor unit bracket is difficult to place due to the small standing space for external operation, which makes it difficult for workers to hold the external bracket while working. Therefore, a foldable outdoor unit mounting bracket for central air conditioning multi-split units is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a foldable mounting bracket for the outdoor unit of a multi-split central air conditioning unit, comprising a mounting bracket body and a placement bracket body. The surface of the mounting bracket body is provided with a folding device, the folding device comprising two rotating rods, the two rotating rods being fixedly connected to the surface of the mounting bracket body, the two rotating rods being rotatably connected to two placement bracket bodies respectively, both ends of the rotating rods being fixedly connected with screw plates, the arc surface of the rotating rods being rotatably connected with two rotating plates, a fixing rod being slidably inserted into each of the two rotating plates, one end of the fixing rod being fixedly connected with a circular plate, a fixing block being fixedly connected to the surface of the mounting bracket body, a fixing hole being formed on the surface of the mounting bracket body, and a support hole being formed on the surface of the placement bracket body.

[0007] The effect achieved by the above-mentioned components is as follows: by setting up a folding device, the external unit bracket can be folded, which avoids the situation where the large external unit bracket is difficult to place due to the limited external working space when the operator is installing the external unit bracket, thus preventing the operator from having to hold the external bracket while working, thereby improving the practicality of the device.

[0008] Preferably, a spring is fitted onto the arc surface of the fixing rod, and the two ends of the spring are fixedly connected to the circular plate and the rotating plate, respectively.

[0009] The aforementioned components achieve the following effect: they provide a stable connection to the fixing rod, preventing shaking caused by external factors from causing the fixing rod to detach from the mounting frame body, thus improving the stability of the device.

[0010] Preferably, a torsion spring is fitted onto the arc surface of the rotating rod, and the two ends of the torsion spring are fixedly connected to the rotating rod and the placement frame body, respectively.

[0011] The aforementioned components achieve the following effect: they automatically unfold the placement rack body, thereby reducing the number of steps required by staff, increasing their work efficiency, and improving the convenience of the device.

[0012] Preferably, a positioning plate is fixedly connected to the surface of the mounting bracket body, and the size of the fixing rod is adapted to the size of the fixing hole.

[0013] The aforementioned components achieve the following effect: they enable quick positioning of the fixing rod, allowing workers to quickly fold the mounting frame and expedite the installation of the external unit bracket.

[0014] Preferably, the surface of the mounting bracket body is provided with a clamping device, the clamping device including two connecting rods, the two connecting rods being fixedly connected to the surface of the mounting bracket body, a support plate being fixedly connected to one end of each of the two connecting rods, a push rod being slidably inserted into the support plate, a clamping plate being fixedly connected to one end of the push rod, a short rod being fixedly connected to one side of the support plate, a short plate being fixedly connected to one end of the short rod, a limiting rod being slidably inserted into the short plate, and a plurality of limiting holes being opened on the surface of the push rod.

[0015] The effect achieved by the above-mentioned components is as follows: by setting up a clamping device, the outdoor unit is clamped after installation, which avoids the outdoor unit from sliding due to gravity when the placement position is offset during installation, thus preventing the outdoor unit from falling off and improving the practicality of the device.

[0016] Preferably, a flexible plate is fixedly connected to the surface of the clamping plate, and the size of the flexible plate is adapted to the size of the clamping plate.

[0017] The effect achieved by the above components is to reduce the friction of the clamping plate on the external unit, thus preventing the protective coating on the surface of the external unit from peeling off due to excessive clamping.

[0018] Preferably, a baffle is fixedly connected to the arc surface of the limiting rod, and the size of the limiting rod is adapted to the size of the limiting hole on the surface of the push rod.

[0019] The effect achieved by the above-mentioned components is to block the limit rod, thus preventing the limit rod from slipping out of the short plate due to shaking during installation, which would otherwise damage the limit rod and make it unusable.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] 1. In this utility model, by setting a folding device, the effect of folding the external unit bracket is achieved, which avoids the situation where the external unit bracket is difficult to place due to the limited external working space when the operator is installing it, thus preventing the operator from having to hold the external bracket while working, thereby improving the practicality of the device.

[0022] 2. In this utility model, by setting a clamping device, the outdoor unit is clamped after installation, which avoids the outdoor unit from sliding due to gravity when the placement position is offset during installation, thus avoiding the risk of the outdoor unit slipping off during installation, thereby improving the practicality of the device.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a foldable mounting bracket for the outdoor unit of a multi-split central air conditioning unit, including a mounting bracket body 1 and a placement bracket body 2. The surface of the mounting bracket body 1 is provided with a folding device 3, which achieves the effect of folding the outdoor unit bracket. This avoids the situation where the outdoor unit bracket is difficult to place due to the limited outdoor working space, thus preventing the worker from having to hold the outdoor unit while performing the installation. This improves the practicality of the device. The surface of the mounting bracket body 1 is provided with a clamping device 4, which achieves the effect of clamping the outdoor unit after installation. This prevents the outdoor unit from sliding due to gravity when the placement position is offset during installation, thus avoiding the risk of the outdoor unit slipping during installation. This further improves the practicality of the device.

[0030] The specific configuration and function of its folding device 3 and clamping device 4 will be explained below.

[0031] Reference Figure 2 , Figure 3As shown in this embodiment: the folding device 3 includes two rotating rods 301, which are fixedly connected to the surface of the mounting frame body 1. The two rotating rods 301 are rotatably connected to two placement frame bodies 2 respectively. Both ends of the rotating rods 301 are fixedly connected to screw plates 302. The arc surface of the rotating rods 301 is rotatably connected to two rotating plates 303. Fixed rods 304 are slidably inserted into the two rotating plates 303. One end of the fixed rod 304 is fixedly connected to a circular plate 306. A fixing block is fixedly connected to the surface of the mounting frame body 1. 308. A fixing hole 309 is provided on the surface of the mounting bracket body 1, and a support hole is provided on the surface of the placement bracket body 2. A spring 305 is fitted onto the arc surface of the fixing rod 304. The two ends of the spring 305 are fixedly connected to the circular plate 306 and the rotating plate 303, respectively. When the circular plate 306 is released, the rebound force of the spring 305 drives the circular plate 306, which in turn drives the fixing rod 304 to slide within the rotating plate 303 until the fixing rod 304 is inserted into the support hole on the surface of the placement bracket body 2. This achieves a stable connection of the fixing rod 304 and avoids damage caused by improper use. External factors causing shaking can cause the fixing rod 304 to detach from the mounting frame body 2, thus improving the stability of the device. The arc surface of the rotating rod 301 is fitted with a torsion spring 310, and the two ends of the torsion spring 310 are fixedly connected to the rotating rod 301 and the mounting frame body 2, respectively. When the fixing of the mounting frame body 2 is released, the torque of the torsion spring 310 drives the mounting frame body 2 to rotate on the arc surface of the rotating rod 301 until the mounting frame body 2 unfolds, achieving the effect of automatically unfolding the mounting frame body 2. This reduces the number of operation steps for the staff, increases the work efficiency of the staff, and improves the convenience of the device. The surface of the mounting frame body 1 is fixedly connected with a positioning plate 307. The size of the fixing rod 304 is matched with the size of the fixing hole 309. By rotating the fixing rod 304, the fixing rod 304 drives the rotating plate 303 to rotate on the arc surface of the rotating rod 301 until the fixing rod 304 touches the positioning plate 307, achieving the effect of quickly positioning the fixing rod 304. This allows the staff to quickly fold the mounting frame body 2 and speed up the installation of the external unit bracket.

[0032] Reference Figure 4 , Figure 5As shown, specifically, the clamping device 4 includes two connecting rods 41, which are fixedly connected to the surface of the mounting frame body 1. A support plate 42 is fixedly connected to one end of each connecting rod 41. A pushing rod 43 is slidably inserted into the support plate 42. A clamping plate 44 is fixedly connected to one end of the pushing rod 43. A short rod 46 is fixedly connected to one side of the support plate 42. A short plate 47 is fixedly connected to one end of the short rod 46. A limiting rod 48 is slidably inserted into the short plate 47. Several limiting holes are opened on the surface of the pushing rod 43. A flexible plate 45 is fixedly connected to the surface of the clamping plate 44. The size of the flexible plate 45 is adapted to the size of the clamping plate 44. Pushing the pushing rod 43 causes it to slide within the support plate 42. The clamping plate 44 moves and drives the flexible plate 45 until the flexible plate 45 is in contact with the outdoor unit. This reduces the friction of the clamping plate 44 with the outdoor unit and prevents the protective coating on the surface of the outdoor unit from peeling off due to excessive clamping. The arc surface of the limiting rod 48 is fixedly connected to the baffle 49. The size of the limiting rod 48 is adapted to the size of the limiting hole on the surface of the push rod 43. When the limiting rod 48 is pulled, the limiting rod 48 slides in the short plate 47. The limiting rod 48 drives the baffle 49 until the baffle 49 abuts against the short plate 47, which achieves the effect of blocking the limiting rod 48. This prevents the limiting rod 48 from slipping out of the short plate 47 due to shaking during installation, which would cause the limiting rod 48 to be damaged and unable to continue to be used.

[0033] Working principle: When the placement rack body 2 is not needed, pushing the placement rack body 2 causes it to rotate on the arc surface of the rotating rod 301 until it fits against the mounting rack body 1. Then, rotating the fixing rod 304 causes the rotating plate 303 to rotate on the arc surface of the rotating rod 301 until the fixing rod 304 touches the positioning plate 307. The fixing rod 304 is then pushed to slide within the rotating plate 303 until it passes through the fixing hole 309 and inserts into the support hole on the surface of the placement rack body 2. When the placement rack body 2 is needed, releasing the fixing of the placement rack body 2 causes the torsion spring 310 to rotate the placement rack body 2 on the arc surface of the rotating rod 301 until the placement rack body 2 unfolds and rotates. The fixed rod 304 drives the rotating plate 303 to rotate on the arc surface of the rotating rod 301 until the fixed rod 304 is perpendicular to the support hole on the surface of the placement frame body 2. Then the circular plate 306 is released, and the rebound force of the spring 305 drives the circular plate 306. The circular plate 306 drives the fixed rod 304 to slide in the rotating plate 303 until the fixed rod 304 is inserted into the support hole on the surface of the placement frame body 2. This achieves the effect of folding the external unit bracket, avoiding the situation where the large external unit bracket is difficult to place due to the limited external working space when the operator is installing the external unit bracket, thus preventing the operator from having to hold the external bracket while working. This improves the practicality of the device.

[0034] By pushing the push rod 43, the push rod 43 slides within the support plate 42, driving the clamping plate 44, which in turn drives the flexible plate 45 until the flexible plate 45 is in contact with the outdoor unit. Then, by pushing the limiting rod 48, the limiting rod 48 slides within the short plate 47, driving the baffle 49 until the limiting rod 48 is inserted into the limiting hole on the surface of the push rod 43. This achieves the effect of clamping the outdoor unit after installation, preventing the outdoor unit from slipping due to gravity caused by a slight deviation in its placement during installation, thus improving the practicality of the device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
