[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0026] The embodiment of the present application provides a retractor to solve the problem of inconvenient installation of an air guide plate. The retractor will be described below with reference to the accompanying drawings.

[0027] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the retractor comprises a sleeve 1, a telescopic member 2 and a rotary cover 3, the telescopic member 2 is arranged in the sleeve 1, the telescopic member 2 is provided with a slot 221, the angle between the extension direction of the slot 221 and the axial direction of the sleeve 1 is less than 90°, the rotary cover 3 is movably connected to one end of the sleeve 1, the rotary cover 3 is provided with a push block 31 which can be embedded in the slot 221, and when the rotary cover 3 moves, the push block 31 slides in the slot 221 to push the telescopic member 2 out of the sleeve 1. It should be noted that the angle between the extension direction of the slot 221 and the axial direction of the sleeve 1 is less than 90°, which means that the extension direction of the slot 221 is inclined relative to the axial direction of the sleeve 1, that is, when the push block 31 slides in the slot 221, the telescopic member 2 can be driven to move forward and backward along the axial direction of the sleeve 1; the rotary cover 3 is movably connected to one end of the sleeve 1, which means that the rotary cover 3 rotates, slides or rolls in the end surface of one end of the sleeve 1 to change the position of the push block 31.

[0028] In this way, the retractor of the present application can be arranged between the air guide plate 4 and the fixed slot, and the air guide plate 4 can be disassembled and assembled by changing the length of the retractor. Specifically, by utilizing the movement of the rotary cover 3, when the push block 31 moves in the direction of exiting the card slot 221, the telescopic member 2 is driven to extend from the sleeve 1, and then the length of the retractor is extended to press against the air guide plate 4 and the fixed slot in the related technology; when disassembling, the rotary cover 3 is rotated in the opposite direction so that the push block 31 is gradually accommodated in the card slot 221, and then the telescopic member 2 is retracted into the sleeve 1, and the length of the retractor is shortened to release the air guide plate 4; the rapid disassembly and assembly of the air guide plate 4 is realized, and the deformation problem of the air guide plate 4 caused by bending the air guide plate 4 to complete the disassembly and assembly in the related technology is solved, so that there is a smaller matching gap between the air guide plate 4 and the inner wall of the air outlet of the air conditioner.

[0029] In some embodiments, Figure 1 and Figure 2 As shown, the push block 31 can be slidably separated from the slot 221 and abutted against the end of the telescopic member 2 to push the telescopic member 2 to gradually extend out of the sleeve 1. In this way, the push block 31 separated from the slot 221 can maintain the extension length of the telescopic member 2 outside the sleeve 1 by abutting against the end of the telescopic member 2, thereby improving the stability of the retractor fixed between the wind guide plate 4 and the fixing slot.

[0030] In some embodiments, Figure 2 As shown, the telescopic member 2 includes an elastic portion 21, a support platform 22 and a fixing rod 23. The two ends of the elastic portion 21 are respectively connected to the sleeve 1 and the support platform 22. The slot 221 is provided on the support platform 22 at one end facing the rotary cover 3. The fixing rod 23 is fixedly connected to the end of the support platform 22 away from the push block 31, and can extend out of the sleeve 1 or retract into the sleeve 1. In this way, when the push block 31 moves in the direction of disengaging from the slot 221, the support platform 22 and the fixing rod 23 move together in the direction away from the rotary cover 3 until the fixing rod 23 extends out of the sleeve 1; when the push block 31 is embedded in the slot 221, the elastic restoring force of the elastic portion 21 drives the support platform 22 to move closer to the rotary cover 3, and the fixing rod 23 moves together with the support platform 22 to move closer to the rotary cover 3 until it is received in the sleeve 1. It should be noted that the elastic part 21 can be a compression spring or a tension spring. When a compression spring is used, the elastic part 21 should be set on the side of the support platform 22 away from the rotary cover 3. When a tension spring is used, the elastic part 21 should be set on the end of the support platform 22 facing the rotary cover 3.

[0031] In some embodiments, Figure 1 and Figure 2As shown, the rotary cover 3 is connected to one end of the sleeve 1 in a rotational manner around the axis of the sleeve 1, the rotation axis of the rotary cover 3 is parallel to the axial direction of the sleeve 1, and the slot 221 extends along the moving direction of the push block 31. Through the above-mentioned rotation of the rotary cover 3, a relatively stable positional relationship between the rotary cover 3 and the sleeve 1 is maintained, which is convenient for improving the stability of the use of the retractor. Exemplarily, the rotary cover 3 is connected to one end of the sleeve 1 in a rotational manner around the axis of the sleeve 1, which can be: the rotation axis of the rotary cover 3 coincides with the axis of the rotary cover 3, or: the axis of the rotary cover 3 rotates around the axis of the sleeve 1.

[0032] In some specific embodiments, the rotary cover 3 is rotatably connected to one end of the sleeve 1 around the axis of the sleeve 1, the rotation axis of the rotary cover 3 is parallel to the axial direction of the sleeve 1, the rotation axis of the rotary cover 3 coincides with the axis of the rotary cover 3, and the extension direction of the slot 221 is spiral.

[0033] In some other embodiments, the rotary cover 3 is connected to one end of the sleeve 1 and reciprocates in the radial direction of the sleeve 1 , and the locking groove 221 extends in the radial direction of the sleeve 1 .

[0034] In some embodiments, Figure 4 and Figure 5 As shown, the end of the support platform 22 facing the rotary cover 3 is provided with a receiving cavity 222 for receiving the push block 31, and the clamping groove 221 is provided on the side wall of the receiving cavity 222, and the push block 31 extends radially along the rotary cover 3 and is embedded in the clamping groove 221. In this way, accommodating the push block 31 in the receiving cavity 222 is convenient for reducing the volume of the retractor, and at the same time, the clamping groove 221 can be arranged as close to the peripheral side of the support platform 22 as possible, so as to increase the torque and facilitate the push block 31 to push the support platform 22 to move.

[0035] In some embodiments, Figure 3 and Figure 5 As shown, a ball 32 is fixedly connected to one end of the rotary cover 3 facing the sleeve 1, and a slide rail 11 is provided at one end of the sleeve 1. The ball 32 is slidably connected in the slide rail 11, and the inner wall of the slide rail 11 limits the ball 32 from escaping in the axial direction of the sleeve 1. On the one hand, the sliding friction between the rotary cover 3 and the sleeve 1 is reduced by the ball 32, and on the other hand, the movement of the rotary cover 3 in the axial direction of the sleeve 1 is limited by the slide rail 11.

[0036] In some embodiments, Figure 3 and Figure 5 As shown, one end of the sleeve 1 is provided with a snap-in channel 12 connected to the slide rail 11, and the snap-in channel 12 is used for the ball 32 to be embedded in the slide rail 11; a plurality of balls 32 are arranged at equal intervals along the circumference of the rotary cover 3, and a plurality of snap-in channels 12 are provided and correspond to the plurality of balls 32 one by one. In this way, the assembly between the rotary cover 3 and the sleeve 1 is completed by embedding the ball 32 in the slide rail 11 through the snap-in channel 12, which is convenient for disassembly.

[0037] In some specific embodiments, two balls 32 are provided, two insertion channels 12 are provided, two push blocks 31 are provided, and two locking grooves 221 are provided.

[0038] In some embodiments, when the rotation axis of the rotary cover 3, the central axis of the rotary cover 3 and the central axis of the sleeve 1 coincide, the extension length of the slot 221 along the axial direction of the sleeve 1 is less than the circumferential distance between the two insertion channels 12, and along the axial direction of the retractor, the insertion channel 12 is arranged away from the slot 221. In this way, when the push block 31 completes a reciprocating slide in the corresponding slot 221, the ball 32 will not escape from the slide rail 11 through the insertion channel 12.

[0039] In some embodiments, the rotary cover 3 is sleeved on the outer wall surface of the end of the sleeve 1, and the ball 32 and the push block 31 are arranged at intervals; the slide rail 11 is arranged on the outer wall surface of the end of the sleeve 1, and the push block 31 is located inside the sleeve 1.

[0040] In some embodiments, Figure 3 As shown, the inner wall of the sleeve 1 is provided with a flange 13, and the elastic part 21 is a spring and is arranged between the flange 13 and the support platform 22; the fixing rod 23 is arranged through the spring. Preferably, the spring is a compression spring, and the movable range of the elastic part 21 is limited by the flange 13, that is, the structure protruding from the inner wall of the sleeve 1, and the support platform 22, so that the spring can be directly installed in the sleeve 1 without being fixed, which is convenient for disassembly and replacement; further, preferably, the spring is welded to the flange 13.

[0041] In some embodiments, Figure 2 As shown, the fixing rod 23 is received in the spring, and the outer diameter of the fixing rod 23 is smaller than the inner diameter of the spring.

[0042] The embodiment of the present application also provides an air-conditioning indoor unit, including a main body, an air guide plate 4 and the above-mentioned retractor. The specific structure of the retractor refers to the above-mentioned embodiment. Since the air-conditioning indoor unit adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
