Description

Technical Field

[0001] This utility model relates to the field of air conditioner evaporator installation technology, and in particular to a quick installation and fixing structure for air conditioner evaporators. Background Technology

[0002] The evaporator in an air conditioning system is a key component. It achieves cooling by causing the low-temperature, low-pressure liquid refrigerant, after being throttled by the expansion valve, to absorb heat and vaporize. Its structure mainly consists of the evaporator core, expansion valve, and air duct. In air conditioning systems, due to technological advancements, the structure of the evaporator has become more complex, consequently increasing the complexity of air conditioning production and installation. Excessive use of self-tapping screws to fix the evaporator affects assembly efficiency, while insufficient screws result in structural instability. Too high a precision evaporator makes machining difficult, while too low a precision evaporator makes assembly difficult. The existing technology suffers from the following problems:

[0003] Existing air conditioner evaporators are typically installed using multiple screws, which makes the installation process cumbersome and reduces efficiency. Furthermore, the lack of a locking mechanism for the air conditioner evaporator during installation prevents it from being quickly tightened. Utility Model Content

[0004] The main purpose of this utility model is to provide a quick installation and fixing structure for air conditioner evaporators, which can effectively solve the problems of cumbersome installation process and inability to achieve quick locking.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick-installation and fixing structure for an air conditioner evaporator includes an air conditioner evaporator, an external U-shaped frame for the air conditioner evaporator, mounting holes fixedly connected to the left and right sides of the outer wall of the transverse side of the U-shaped frame, a quick-fixing component for the inner wall of the bottom transverse side of the U-shaped frame, and a locking component for the inner wall of the top transverse side of the U-shaped frame.

[0007] Preferably, the quick-fixing assembly includes two fixing plates, an internally threaded sleeve, a screw, a movable sleeve, a limiting sleeve, a limiting rod, and four plugs. The front side of the outer wall of the internally threaded sleeve is rotatably connected to the inner wall of the movable sleeve. The outer wall of the screw is threadedly connected to the inner wall of the internally threaded sleeve. The outer wall of the limiting rod is sleeved with the inside of the limiting sleeve. One end of the two plugs is fixedly connected to the left and right sides of the opposite surfaces of the two fixing plates, respectively.

[0008] Preferably, the front ends of the movable sleeve and the limiting sleeve are fixedly connected to the left side of the front fixed plate, the rear ends of the screw and the limiting rod are fixedly connected to the left and right sides of the rear fixed plate, and the front fixed plate is fixedly connected to the front side of the inner wall of the transverse surface of the U-shaped frame.

[0009] Preferably, limiting grooves are respectively opened on the left and right sides of the bottom horizontal surface of the U-shaped frame, and sliders are respectively fixedly connected to the left and right sides of the bottom of the rear fixing plate, and the outer wall of the slider is slidably connected to the inner wall of the limiting groove.

[0010] Preferably, the bottom of the front and rear ends of the air conditioner evaporator is provided with two sockets that are compatible with the plug, and the outer wall of the plug is inserted into the inside of the socket.

[0011] Preferably, the top of the air conditioner evaporator is provided with a locking groove.

[0012] Preferably, the locking assembly includes a locking block, several telescopic rods, and several high-strength springs. The lower ends of the inner tubes of the several telescopic rods are equidistantly arrayed and fixedly connected to the top of the locking block. The interior of the high-strength spring is sleeved with the exterior of the telescopic rod. The front surface of the locking block is set to a bevel shape.

[0013] Preferably, the inner wall of the top transverse surface of the U-shaped frame is provided with an installation groove, and the outer rod tubes of several telescopic pull rods are fixedly connected to the top of the inner wall of the installation groove. The lower end of the high-strength spring overlaps the top of the locking block, the upper end of the high-strength spring overlaps with the inner wall of the installation groove, and the outer wall of the locking block is engaged with the inner wall of the locking groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model provides a quick installation and fixing structure for an air conditioner evaporator. It adopts the cooperation between the air conditioner evaporator, U-shaped frame, mounting hole plate and quick fixing components. The U-shaped frame is fixed to the air conditioner's installation channel with bolts. Then, the U-shaped frame is inserted obliquely between two fixing plates and straightened. The distance between the two fixing plates is adjusted by using threads. The bottom of the air conditioner evaporator is then snapped and fixed. This solves the problem that the existing air conditioner evaporators are usually installed with multiple screws, which is cumbersome and reduces installation efficiency. It achieves the beneficial effect of simple installation and quick installation and fixing of the air conditioner evaporator.

[0016] 2. This utility model provides a quick installation and fixing structure for an air conditioner evaporator. It utilizes the cooperation between the air conditioner evaporator, a U-shaped frame, and a locking assembly. When the air conditioner evaporator is installed within the U-shaped frame, the evaporator presses against the locking assembly, causing the surface of the locking block to compress a high-strength spring. The high-strength spring deforms inward under pressure, moving the locking block into the limiting groove. After the air conditioner evaporator is vertically positioned within the U-shaped frame, the locking block uses its restoring elasticity to snap it into the locking groove and lock it in place. This solves the problem of the lack of a locking structure for the air conditioner evaporator during installation, which prevents quick locking, and achieves the beneficial effect of quickly locking the air conditioner evaporator during installation.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, a quick installation and fixing structure for an air conditioner evaporator includes an air conditioner evaporator 1, an air conditioner evaporator 1 with a U-shaped frame 2 on the outside, mounting holes 3 fixedly connected to the left and right sides of the outer wall of the transverse side of the U-shaped frame 2, a quick fixing component 4 on the inner wall of the bottom transverse side of the U-shaped frame 2, and a locking component 5 on the inner wall of the top transverse side of the U-shaped frame 2.

[0025] The system consists of an air conditioner evaporator 1, a U-shaped frame 2, a mounting plate 3, a quick-fix assembly 4, and a locking assembly 5. The air conditioner evaporator 1 is tilted and inserted between the quick-fix assembly 4 through the cooperation of the U-shaped frame 2 and the quick-fix assembly 4. The bottom of the air conditioner evaporator 1 is clamped and positioned by means of threads. Then, the top of the air conditioner evaporator 1 is locked by means of spring clips.

[0026] like Figure 2 As shown, this utility model provides a technical solution for a quick installation and fixing structure for an air conditioner evaporator: the quick fixing assembly 4 includes two fixing plates 41, an internally threaded sleeve 42, a screw 43, a movable sleeve 44, a limiting sleeve 45, a limiting rod 46, and four plugs 47. The front side of the outer wall of the internally threaded sleeve 42 is rotatably connected to the inner wall of the movable sleeve 44. The outer wall of the screw 43 is threadedly connected to the inner wall of the internally threaded sleeve 42. By rotating the internally threaded sleeve 42, the screw 43 can be driven to extend and retract, thereby controlling the distance between the two internally threaded sleeves 42. The limiting rod... The outer wall of 46 is sleeved with the inside of the limiting sleeve 45. The outer side of the limiting rod 46 slides along the inside of the limiting sleeve 45 to limit the movement trajectory of the fixed plate 41. One end of the front and rear plugs 47 are fixedly connected to the left and right sides of the opposite faces of the two fixed plates 41 respectively. The front ends of the movable sleeve 44 and the limiting sleeve 45 are fixedly connected to the left side of the front fixed plate 41 respectively. The rear ends of the screw 43 and the limiting rod 46 are fixedly connected to the left and right sides of the rear fixed plate 41 respectively. The front fixed plate 41 is fixedly connected to the front side of the inner wall of the transverse surface of the U-shaped frame 2.

[0027] like Figure 3 As shown, this utility model provides a quick installation and fixing structure for an air conditioner evaporator: Limiting grooves 201 are respectively opened on the left and right sides of the bottom horizontal surface of the U-shaped frame 2, and sliders 411 are respectively fixedly connected to the left and right sides of the bottom of the rear fixing plate 41. The outer wall of the slider 411 is slidably connected to the inner wall of the limiting groove 201, and the slider 411 slides along the limiting groove 201, which improves the stability of the movement of the rear fixing plate 41.

[0028] like Figure 4 As shown, this utility model provides a quick installation and fixing structure for an air conditioner evaporator: two sockets 101 adapted to plug 47 are respectively opened at the bottom of the front and rear ends of the air conditioner evaporator 1. The outer wall of plug 47 is inserted into the inside of socket 101. Plug 47 is inserted into socket 101 to fix the bottom of the air conditioner evaporator 1. A locking groove 102 is opened at the top of the air conditioner evaporator 1.

[0029] like Figure 5As shown, this utility model provides a technical solution for a quick installation and fixing structure for an air conditioner evaporator: the locking assembly 5 includes a locking block 51, several telescopic pull rods 52, and several high-strength springs 53. The lower ends of the inner rods of the telescopic pull rods 52 are equidistantly arrayed and fixed to the top of the locking block 51. The interior of the high-strength springs 53 is sleeved with the exterior of the telescopic pull rods 52. Utilizing the elasticity of the high-strength springs 53, the inner rods of the telescopic pull rods 52 can freely extend and retract along the outer rods after the locking block 51 is subjected to force, moving into the mounting groove 202 and locking. The front surface of the plug 51 is set as a bevel shape. The inner wall of the top horizontal surface of the U-shaped frame 2 is provided with an installation groove 202. The outer rod tubes of several telescopic pull rods 52 are fixedly connected to the top of the inner wall of the installation groove 202. The lower end of the high-strength spring 53 overlaps the top of the locking plug 51, and the upper end of the high-strength spring 53 overlaps with the inner wall of the installation groove 202. The outer wall of the locking plug 51 is engaged with the inner wall of the locking groove 102. Utilizing the elasticity of the high-strength spring 53, the locking plug 51 is snapped into the locking groove 102, thereby locking the top of the air conditioner evaporator 1.

[0030] The working principle of this quick-installation and fixing structure for air conditioner evaporators will be explained in detail below.

[0031] like Figure 1-5 As shown, firstly, the U-shaped frame 2 is installed in the mounting slot of the air conditioner. Screws are used to fix the U-shaped frame 2 inside the mounting slot via the mounting hole plate 3. Then, the lower end of the air conditioner evaporator 1 is inserted obliquely between the two fixing plates 41. Next, the upper half of the air conditioner evaporator 1 is pressed into the interior of the U-shaped frame 2. During the pressing process, the surface of the locking block 51 is subjected to force, causing the inner rod tube of the telescopic pull rod 52 to slide inward along the outer rod tube. This causes the high-strength spring 53 to deform under pressure, squeezing the locking block 51 into the mounting slot 202. When the air conditioner evaporator 1 is vertically positioned inside the U-shaped frame 2, By rotating the internal threaded sleeve 42, the limiting rod 46 retracts along the limiting sleeve 45, causing the screw 43 to retract into the internal threaded sleeve 42. This, in turn, causes the two fixing plates 41 to slide along the limiting groove 201 via the slider 411 until they are clamped at both ends of the air conditioner evaporator 1, allowing the plug 47 to be inserted into the socket 101 and fixed. Then, the locking groove 102 and the locking plug 51 are aligned, and the high-strength spring 53 immediately causes the locking plug 51 to snap into the locking groove 102 and lock, thus achieving quick installation, fixing and locking of the air conditioner evaporator 1, which is convenient for disassembly.
