Description

Technical Field

[0001] The invention relates to the technical field of air duct heaters, and in particular to a shock-absorbing and impact-proof component of an air duct heater. Background Art

[0002] Duct heater refers to a heating device that heats the air in the duct. Electric heating is the process of converting electrical energy into thermal energy. The specifications are divided into three types: low temperature, medium temperature and high temperature. It has the characteristics of small wind resistance, uniform heating and high safety performance.

[0003] When the existing air duct heater is in use, when the wind speed of the fan is too fast and the wind force is too strong, it is easy to generate impact force on the heating tube, causing the heating tube assembly to vibrate and easily cause damage to the heating tube assembly. Therefore, a shock-absorbing and impact-proof assembly of the air duct heater is needed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcoming in the prior art that the heating tube is easily damaged by the impact force of wind, and to propose a shock-absorbing and impact-proof component for an air duct heater.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A shock-absorbing and impact-proof component of an air duct heater comprises a heating box and a heating tube component, wherein a square groove is provided on the outside of the heating box, a square plate is installed on the outside of the heating tube component, the square groove is rotatably connected to the square plate, a U-shaped plate is installed on the outside of the square plate, a plurality of guide plates are symmetrically rotatably connected to the inner part of the U-shaped plate, a plurality of second fixing plates are symmetrically installed on the inside of the U-shaped plate, a second spring is installed on the outside of the second fixing plate, the second spring is fixedly connected to the guide plate, a plurality of impact-proof components are arranged on the outside of the U-shaped plate, and the impact-proof components each comprise a first round rod installed on the outside of the U-shaped plate, the first round rod is installed on the outside of the U-shaped plate, and the second round rod is installed on the outside of the U-shaped plate. A round rod is rotatably connected to a first round ring on the outside, a damping rod is installed on the outside of the first round ring, a first spring is sleeved on the outside of the damping rod, a second round ring is installed on the other end of the damping rod away from the first round ring, the second round ring is rotatably connected to a second round rod on the outside, a first fixing plate is installed on the outside of the second round rod, the first fixing plate is fixedly connected to the inner wall of the heating box, and is rotatably connected between the heating tube assembly and the square groove, and an anti-impact assembly is arranged at the bottom of the U-shaped plate. When the fan blows the U-shaped plate, the heating tube assembly is cushioned by the cushioning U-shaped plate to avoid damage to the heating tube assembly due to excessive wind speed and strong wind force.

[0007] The above technical solution further includes: a first rotating rod is installed inside the square groove, and the first rotating rod is rotatably connected to the heating tube assembly.

[0008] A second curved plate is installed on the outside of the square plate, and a first curved plate is installed on the inner wall of the heating box.

[0009] A second rotating rod is installed inside the U-shaped plate, and the second rotating rod is rotatably connected to the guide plate.

[0010] The guide plates are in multiple groups and are vertically distributed.

[0011] The size of the square slot opening is matched with the size of the square plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the present invention, a rotating connection is set between the heating tube assembly and the square groove, and an anti-impact assembly is set at the bottom of the U-shaped plate. When the fan blows the U-shaped plate, the shock-absorbing U-shaped plate can provide a shock-absorbing effect on the heating tube assembly to prevent the wind speed from being too fast and the wind force from being too strong, thereby preventing the heating tube assembly from vibrating and causing damage to the heating tube assembly.

[0014] 2. In the present invention, a plurality of guide plates are symmetrically installed on the outside of the U-shaped plate. When the fan blows the heating tube assembly for heating, the wind is guided by the plurality of guide plates, and the wind force is concentrated and discharged through the exhaust port, thereby preventing the wind force from running around in the heating box and affecting the heating efficiency.

The outside of the second circular ring 11 is rotatably connected to a second circular rod 12, and a first fixed plate 13 is installed on the outside of the second circular rod 12. The first fixed plate 13 is fixedly connected to the inner wall of the heating box 1, and a first rotating rod 3 is installed inside the square groove 2. The first rotating rod 3 is rotatably connected to the heating tube assembly 4. A second arc plate 15 is installed outside the square plate 5, and a first arc plate 14 is installed on the inner wall of the heating box 1. The size of the opening of the square groove 2 is adapted to the size of the square plate 5.

[0025] A working principle based on the first embodiment is that a square plate 5 is installed on the outside of the heating tube assembly 4, and then the square plate 5 is rotatably connected between the first rotating rod 3 and the square groove 2, and a U-shaped plate 6 is installed on the outside of the heating tube assembly 4. When the fan blows air, the U-shaped plate 6 is blown, and when the bottom of the U-shaped plate 6 is tilted by the wind, the damping rod 9 is rotatably connected to the U-shaped plate 6 through the first round rod 7 and the first ring 8, and is rotatably connected to the first fixed plate 13 through the second ring 11 and the second round rod 12. Then the U-shaped plate 6 performs a shock-absorbing effect through the damping rod 9 and the first spring 10, so as to cushion the shock of the heating tube assembly 4 through the U-shaped plate 6 to prevent the wind speed from being too fast and the wind force from being too strong, which may cause the heating tube assembly 4 to vibrate and cause damage to the heating tube assembly 4.
