[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0016] See also Figures 1 to 4, which is the first embodiment of the utility model, and this embodiment provides a technical solution: a bending-resistant air-conditioning PCB board, comprising an air-conditioning PCB board body 1, an adjustable anti-bending mechanism is arranged on the top of the air-conditioning PCB board body 1, and the adjustable anti-bending mechanism comprises a reinforcing beam 21 and a strip support beam 22, two reinforcing beams 21 are symmetrically fixed on the top surface of the air-conditioning PCB board body 1, and the strip support beam 22 is installed between the two reinforcing beams 21, and the reinforcing beam 21 and the strip support beam 22 form an "I"-shaped support structure, thereby supporting the air-conditioning PCB board body 1 The strip support beam 22 has the effect of strengthening the support and resisting bending. Both end surfaces of the strip support beam 22 are fixed with T-shaped slide seats 26. The surface of the reinforcing beam 21 is provided with a T-shaped slide groove 23 corresponding to the T-shaped slide seat 26. The T-shaped slide seat 26 is slidably located in the T-shaped slide groove 23, so that the position of the strip support beam 22 can be adaptively adjusted according to the position of the electronic components on the top of the air conditioner PCB board body 1, thereby increasing flexibility. The adjustable anti-bending mechanism also includes a positioning structure 25 arranged at both ends of the strip support beam 22. The positioning structure 25 includes a sliding sleeve arranged on the end surface of the strip support beam 22. The U-shaped sliding sleeve 251, the positioning structure 25 also includes a rod groove 252 opened inside the strip support beam 22 and an inner sliding groove 254 opened inside the T-shaped sliding seat 26, a spring 255 and an inner sliding block 256 are arranged in the inner sliding groove 254, a limiting card block 257 is fixed on one side of the inner sliding block 256, and a plurality of limiting card grooves 258 corresponding to the limiting card block 257 are evenly opened on the inner wall of the T-shaped sliding groove 23, and the end of the limiting card block 257 penetrates into one of the limiting card grooves 258, so as to realize the stable limiting of the T-shaped sliding seat 26 in daily use, thereby To ensure the position stability of the strip support beam 22, thereby providing effective anti-bending support for the air-conditioning PCB board body 1, a movable rod 253 is fixed to the other side surface of the inner slider 256, and the end of the movable rod 253 passes through the rod groove 252. Both side surfaces of the strip support beam 22 are provided with connecting slides 2510 that are connected to the rod groove 252. A connecting slider 259 is arranged in the connecting slide 2510, and one end of the connecting slider 259 is fixedly connected to the movable rod 253, and the other end of the connecting slider 259 is fixedly connected to the inner wall of the U-shaped sliding sleeve 251.If the position of the strip support beam 22 needs to be adjusted later, the U-shaped sliding sleeve 251 only needs to be pulled toward the center of the strip support beam 22, so that the connecting slider 259 pulls the movable rod 253 sideways, and the inner slider 256 moves sideways with the limiting block 257, and the spring 255 is compressed until the end of the limiting block 257 moves out of the limiting groove 258, so that the limit on the T-shaped slide 26 can be released. At this time, the T-shaped slide 26 can be slid in the T-shaped groove 23 to adjust the position of the strip support beam 22, so that the position of the strip support beam 22 can be adjusted according to the air conditioner P The position of the electronic components on the top of the CB board body 1 is adaptively adjusted to increase flexibility. When the strip support beam 22 is adjusted to a suitable position, the U-shaped sleeve 251 is loosened, and the spring 255 pushes the inner slider 256 back to reset, and the end of the limit block 257 is inserted into the limit slot 258 at other positions, so that the T-shaped slide 26 can be limited again, thereby completing the stable limit of the strip support beam 22 after the position adjustment, ensuring that the strip support beam 22 and the reinforcing beam 21 can effectively reinforce and support the air conditioner PCB board body 1 and resist bending.

[0017] Among them, one end of the spring 255 is against the inner wall of the inner slide groove 254, and the other end of the spring 255 is against the inner slider 256. A pop-up hole corresponding to the limit block 257 is opened on one side surface of the T-shaped slide seat 26, and the pop-up hole is communicated with the inner slide groove 254 to allow the limit block 257 to pop out smoothly. A rod hole corresponding to the movable rod 253 is opened on the other side surface of the T-shaped slide seat 26, and the rod hole coincides with the rod groove 252 to allow the movable rod 253 to pass through smoothly.

[0018] Among them, reserved mounting holes are arranged at the four corners of the air conditioner PCB board body 1, and the reserved mounting holes are circular for fixing the air conditioner PCB board body 1 to the external substrate at a later stage. Example 2

[0019] See also Figures 1 to 4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and the difference is that the anti-slip fixing screws 24 can be set to play an anti-slip limiting effect when the strip support beam 22 slides to adjust the position, thereby preventing the strip support beam 22 from directly sliding and separating from the reinforcing beam 21 when the position is adjusted. The anti-slip fixing screws 24 can be removed at a later stage, and then a new strip support beam 22 can be added and slidably installed between the two reinforcing beams 21, so as to adaptively increase or decrease the number of strip support beams 22 and adjust the anti-bending effect.

[0020] The anti-slipping fixing screw 24 is a screw threaded end of the anti-slipping fixing screw 24 that penetrates the reinforcing beam 21. The anti-slipping fixing screw 24 can prevent the T-shaped slide 26 from sliding directly from the opening of the T-shaped slide groove 23, thereby preventing the strip support beam 22 from falling off when the sliding adjustment position is set. The operator can also remove the anti-slipping fixing screw 24 in the later stage, and then add a new strip support beam 22 to be slidably installed between the two reinforcing beams 21, so as to adaptively increase or decrease the number of strip support beams 22 and adjust the anti-bending effect. The top surface of the air conditioning PCB board main body 1 is provided with a threaded groove corresponding to the anti-slipping fixing screw 24, and the surface of the reinforcing beam 21 is penetrated with a screw hole for the anti-slipping fixing screw 24 to penetrate. The bottom end of the anti-slipping fixing screw 24 is screwed into the threaded groove, so that the reinforcing beam 21 can be smoothly fixed to the top of the air conditioning PCB board main body 1 through the anti-slipping fixing screw 24.
