Description

Technical Field

[0001] The utility model relates to the technical field of heater casings, in particular to a vehicle heater casing which is easy to repair. Background Art

[0002] With the continuous development of the automotive industry, car heaters play a vital role in regulating the internal environment of cars. However, traditional car heater housings have many inconveniences during use. In previous car heater designs, the housings usually adopt a relatively complex structure, and the installation and disassembly process is cumbersome, consuming a lot of time and manpower. When the heater malfunctions and needs to be repaired, it is often necessary to disassemble the entire housing, which is not only difficult to operate but also easy to damage the equipment during the disassembly process, increasing maintenance costs. Moreover, frequent overall disassembly can also cause loosening and damage to the connection parts, affecting the service life and performance stability of the heater. In addition, traditional heater housings have shortcomings in fault detection. It is impossible to make a preliminary judgment on internal faults without large-scale disassembly. This requires maintenance personnel to perform a lot of tentative operations to determine the fault point, further extending maintenance time. Utility Model Content

[0010] 1. The utility model provides an outer shell device. When installing the heater casing, it is only necessary to align the top of the outer casing with the bottom of the inner casing and slide it along the inner wall of the fixed frame. The bottom of the inner casing contacts the top inclined surface of the clamping block to move the clamping block outward. When the outer casing contacts the inner casing, the clamping block automatically slides into the clamping groove under the action of the pressure spring to fix the inner casing device. The installation process is simple and fast. When it needs to be dismantled for maintenance, the pressure plate can be pressed to separate the clamping block from the clamping groove, and the inner casing can be easily separated from the outer casing, thereby realizing the rapid separation of the outer shell device and the inner casing device, greatly improving the maintenance efficiency and saving maintenance time and labor costs.

[0011] 2. The utility model provides an inner housing device, so under normal circumstances, internal faults can be checked through the inspection slot without removing the entire housing device. Pulling and turning the handle causes the sliding block to move along the slide rod, causing the baffle to no longer block the inspection slot, allowing internal faults to be observed and checked through the inspection slot. This avoids unnecessary disassembly work and reduces the risk of damage to the equipment caused by frequent disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the rotating handle 28 is released and the sliding block 25 is pulled back by the tension spring 26, causing the rotating handle 28 to be stuck in the limit groove 291.

[0027] The outer shell device 1 includes an outer shell 11, and the outer wall of the outer shell 11 is symmetrically fixedly connected with an air duct 111, and the air duct 111 is communicated with the interior of the outer shell 11. The outer wall of the outer shell 11 is fixedly connected with a fixing frame 12, and the top of the fixing frame 12 is symmetrically opened with a fixing groove 121. The inside of the fixing groove 121 is fixedly connected with a fixing rod 14, the outer wall of the fixing rod 14 is slidably connected with a clamping block 13, and the outer wall of the clamping block 13 is fixedly connected with a pressure spring 15.

[0028] The outer wall of the pressure spring 15 away from the side of the clamping block 13 is fixedly connected to the inner wall of the fixing groove 121, the outer wall of the bottom of the clamping block 13 is slidably connected to the inner wall of the fixing groove 121, the outer wall of the top of the clamping block 13 is slidably connected to the inner wall of the clamping groove 211, the inner wall of the fixing frame 12 is slidably connected to the outer wall of the inner casing 21, the outer wall of the top of the outer casing 11 is in contact with the outer wall of the bottom of the inner casing 21, the outer wall of the top of the clamping block 13 is in contact with the outer wall of the bottom of the pressure plate 222, and the clamping block 13 is separated from the clamping groove 211 along the fixing groove 121 by pressing the pressure plate 222 to contact it, and then the inclined surface of the bottom of the pressure plate 222 slides with the inclined surface of the top of the clamping block 13.

[0029] Working principle: When installing the heater casing, align the top of the outer casing 11 with the bottom of the inner casing 21 and slide along the inner wall of the fixing frame 12. The bottom of the inner casing 21 contacts the inclined surface of the top of the clamping block 13, so that the clamping block 13 moves outward along the fixing groove 121. When the outer casing 11 contacts the inner casing 21, the clamping block 13 is also aligned with the clamping groove 211. The pressure spring 15 outside the fixing rod 14 connected by the sliding inner wall of the clamping block 13 pushes the clamping block 13 to slide into the clamping groove 211, thereby fixing the inner casing device 2 as a whole. When it needs to be dismantled for maintenance, press the outer wall of the inner casing 21 to press the clamping block 13. The pressing plate 222 slides downward along the outer wall of the inner casing 21 and the inner wall of the slot of the positioning plate 22, and the supporting spring 223 is compressed. Then, the inclined surface at the bottom of the pressing plate 222 slides with the inclined surface at the top of the clamping block 13, and the clamping block 13 is separated from the clamping groove 211 along the fixing groove 121, so that the inner casing 21 is separated from the outer casing 11, and the outer casing device 1 is separated from the inner casing device 2. Then, the pressing plate 222 is released, and the pressing plate 222 is slid upward and reset by the rebound force of the supporting spring 223. At the same time, the limit block 224 at the top of the positioning rod 221 limits the pressing plate 222 to prevent it from falling off.

[0030] Under normal circumstances, when it is necessary to check whether maintenance is required, there is no need to dismantle the entire casing device. First, check whether there is any internal fault through the inspection slot 214, pull the rotating handle 28 on the sliding block 25 to separate it from the limit slot 291 on the limit plate 29, and then turn the rotating handle 28 upward. At this time, the tension of the tension spring 26 pulls the sliding block 25 along the slide rod 24 and the sliding slot 213 at the bottom toward the fixed plate 23. At the same time, the baffle 27 fixedly connected to the sliding block 25 moves outward along the fixed plate 23 so that the baffle 27 no longer blocks the inspection slot 214, and vice versa. At this time, the inspection slot 214 can be used to observe and check whether there is any internal fault. The ventilation slot 212 at the top of the inner casing 21 helps to dissipate heat from the internal heater, and the heater takes in and out air through the air duct 111 on the outer casing 11.
