Description

Technical Field

[0001] The utility model relates to the field of duct machine installation, in particular to an installation structure of a signal receiving box of a duct machine. Background Art

[0002] The control of the duct machine is generally achieved through the cooperation of the remote control and the smart receiving box. When installing the smart receiving box, the general practice is to directly place the receiving box in the return air box of the unit and connect it to the interface reserved for the receiving box on the main control panel of the duct machine. The side of the smart receiving box is provided with a horizontally arranged sleeve spring shaft and a matching vibration-damping spring, which is used to prevent the vibration generated when the duct machine is working from causing the receiving box to fall off. However, when the smart receiving box is conventionally installed in the duct machine, the user's signal reception effect is poor due to the several blades set at the air outlet of the duct machine blocking the remote control from receiving the signal during use, which seriously affects the user experience. In addition, you can choose to install it on the ceiling. By opening a hole in the ceiling, the side of the smart receiving box used to receive the signal is placed under the ceiling through the hole and exposed to the outside, and then fixed to the hole with tape. This installation method makes the signal reception no longer blocked. However, the receiving box itself has a certain weight, and the force used to fix it with tape is insufficient. At the same time, gypsum boards are generally used on the ceiling of houses. When encountering humid climates, water droplets are easily condensed, causing the tape to lose its adhesion. Therefore, how to install the remote control signal receiving box of the duct machine becomes a difficult problem. Utility Model Content

[0027] The utility model is further described below in conjunction with the accompanying drawings.

[0028] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain the utility model and are not used to limit the utility model.

[0029] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by the terms "upper", "lower", "horizontal", "middle", etc. should be understood in a broad sense and are not used to limit the scope of protection of the present invention. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The utility model provides a signal receiving box installation structure for a duct machine, comprising a signal receiving box 1, a mounting plate 2 and a torsion spring 3.

[0031] like Figure 6 As shown, a spring shaft is provided on the side of the signal receiving box 1 for mounting a spring.

[0032] like Figure 8 As shown, the mounting plate 2 is provided with mounting holes penetrating the upper and lower surfaces thereof. The mounting plate 2 is usually a ceiling made of gypsum, but may also be other mounting media. The mounting holes are used to install the signal receiving box 1, so that the signal receiving box 1 can receive the remote control signal without obstruction after installation.

[0033] like Figure 7 As shown, the torsion spring 3 includes a coil, a first torsion arm and a second torsion arm, and is used to transmit a pressing force to the signal receiving box 1 so that the signal receiving box 1 is stably mounted on the mounting plate 2 .

[0034] like Figure 4 , Figure 5 As shown, during installation, the first torsion arm of the torsion spring 3 abuts against the lower surface of the mounting plate 2, and the second torsion arm of the single torsion spring 3 extends from the lower surface of the mounting plate 2 into the mounting hole of the mounting plate 2. The construction personnel pull the second torsion arms of the two torsion springs 3 upward until the limiting protrusion of the signal receiving box 1 abuts against the lower surface of the mounting plate 2, and then fasten the second torsion arm to the mounting plate 2 to complete the installation.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, the installation structure of the signal receiving box of the duct machine after installation, the coil of the torsion spring 3 is sleeved on the sleeve spring shaft of the signal receiving box 1, the first torsion arm of the torsion spring 3 abuts against the inner wall of the mounting hole of the mounting plate 2, and is used to provide a horizontal clamping force to the signal receiving box 1, the second torsion arm of the torsion spring 3 abuts against the upper surface of the mounting plate 2, and is used to provide a downward clamping force to the signal receiving box 1, the signal receiving box 1 is also provided with a limiting protrusion, the limiting protrusion abuts against the lower surface of the mounting plate 2, and is used to provide an upward clamping force to the signal receiving box 1, the three cooperate with each other to enable the signal receiving box 1 to be firmly installed in the mounting hole of the mounting plate 2.

[0036] Preferably, the first torsion arm of the torsion spring 3 is provided with a first bending portion, the first bending portion abuts against the inner wall of the mounting hole of the mounting plate 2, and the end of the first torsion arm of the torsion spring 3 away from the coil abuts against the signal receiving box 1. In this scheme, the first torsion arm of the torsion spring 3 may also not be provided with the first bending portion. If the end of the first torsion arm of the torsion spring 3 away from the coil is toward the inner wall of the mounting hole of the mounting plate 2 and abuts against the inner wall of the mounting hole of the mounting plate 2, when the signal receiving box 1 is disassembled, the inner wall of the mounting hole of the mounting plate 2 may be scratched and the first torsion arm of the torsion spring 3 may be damaged. Therefore, it is preferred that the end of the first torsion arm of the torsion spring 3 away from the coil is toward the signal receiving box 1 and abuts against the signal receiving box 1, so that the abutment between the first torsion arm of the torsion spring 3 and the inner wall of the mounting hole of the mounting plate 2 tends to be smooth, which is convenient for protecting the torsion spring 3 during disassembly. When the end of the first torsion arm of the torsion spring 3 away from the coil abuts against the signal receiving box 1, the vertical static friction provided by the first torsion arm will make the signal receiving box 1 more firmly installed.

[0037] Preferably, the second torsion arm of the torsion spring 3 is provided with a second bent portion, and the second bent portion to the end of the second torsion arm away from the coil abuts against the upper surface of the mounting plate 2. The second bent portion may not be provided in this scheme, but when the end of the second torsion arm of the torsion spring 3 away from the coil abuts against the upper surface of the mounting plate 2, the contact range between the second torsion arm and the upper surface of the mounting plate 2 is too small, and the uneven force on the second torsion arm can easily cause the torsion arm to break. At the same time, the small contact area also leads to insufficient downward clamping force. Therefore, it is preferred to provide a second bent portion, and the second bent portion abuts against the upper surface of the mounting plate 2 to increase the contact range between the second torsion arm and the upper surface of the mounting plate 2 as much as possible, thereby protecting the torsion spring 3 and strengthening the force.

[0038] Preferably, the coils of the torsion spring also include a first coil and a second coil, the central axes of the first coil and the second coil are coaxial, the first torsion arm is a U-shaped structure, one end of the first torsion arm is fixedly connected to an end of the first coil close to the second coil, and the other end of the first torsion arm is fixedly connected to an end of the second coil close to the first coil, the second torsion arm also includes a second torsion arm A and a second torsion arm B, the second torsion arm A is arranged on an end of the first coil away from the second coil, and the second torsion arm B is arranged on an end of the second coil away from the first coil. Compared with the strength of a single torsion spring, this double-coil and double-torsion-arm torsion spring 2 has higher strength, so this solution is preferably adopted.

[0039] More preferably, the installation structure of the signal receiving box of the duct machine also includes a pull handle 4, and the pull handle 4 also includes an interface A and an interface B. The interface A is fixedly connected to the end of the second torsion arm A away from the coil, and the interface B is fixedly connected to the end of the second torsion arm B away from the coil. The pull handle 4 can not only connect the second torsion arm A and the second torsion arm B to make the whole more solid, but also facilitate the operation of construction personnel, provide a fulcrum, reduce the difficulty of operation for operators, and improve installation efficiency.

[0040] Preferably, the limiting protrusion of the signal receiving box 1 is a cover plate, which is a structure of the signal receiving box 1 itself. The cover plate is provided with a signal receiver and a display screen. The cover plate is used to press against the lower surface of the mounting plate 2 along the edge to provide an upward clamping force for the signal receiving box 1, and cooperates with two torsion springs 3 to achieve a stable installation, while being able to display the display screen to the user and receive remote control signals.

[0041] More preferably, the signal receiving box 1 is provided with a sleeve spring shaft on at least two mutually parallel sides, and there are at least two torsion springs 3, each sleeve spring shaft is provided with a torsion spring 3, and the torsion springs are provided on at least two mutually parallel sides so that the force on both sides of the signal receiving box 1 can be balanced.

[0042] The above implementation modes are only preferred implementation modes of the present utility model and do not limit the protection scope of the present utility model. Any equivalent changes or equivalent replacements made to the technical solutions on the basis of the technical solutions of the present utility model shall fall within the protection scope of the present utility model.

[0043] The preparation process and processing method of the signal receiving box installation structure of the duct machine provided by the utility model are not limited. For technicians in this field, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
