Description

Technical Field

[0001] The utility model relates to a clothes drying machine, in particular to a folding telescopic frame and a main machine installation structure of an electric clothes drying machine. Background Art

[0002] The development of electric clothes drying racks can be traced back to the rapid development of folding and telescopic rack technology in recent years, as well as consumers' demand for functionality and convenience of clothes drying racks.

[0003] The grid-type and scissor-type telescopic racks have improved the bending resistance of the clothes drying rack to a certain extent, but because there are only two layers of riveted connecting plates, the structure is relatively thin and still not stable and reliable enough. With the continuous development of science and technology, today's electric clothes drying racks have more advanced and stable folding telescopic rack technology. These technologies not only improve the bending strength of the clothes drying rack, but also enhance its stability and reliability.

[0004] For example, the utility model patent with authorization announcement number CN207435776U discloses an electric clothes drying machine and its telescopic bracket, which includes a folding section with a pivot hole, two mounting parts arranged at both ends of the folding section, and a sliding assembly connecting the folding section and the mounting parts. Any sliding assembly includes a fixing pin and two concave parts sleeved on both ends of the fixing pin, the fixing pin passes through the pivot hole at the end of the folding section, and the two concave parts are arranged on opposite sides of the folding section, and the two concave parts slide in cooperation with the corresponding mounting parts.

[0005] For example, the invention patent with application publication number CN108589202A discloses a telescopic support structure of a clothes drying rack, comprising: a mounting frame, used to mount the telescopic support structure on the main body of the clothes drying rack, the mounting frame being provided with at least two waist-shaped holes; a scissor-type telescopic mechanism, the scissor-type telescopic mechanism comprising a plurality of hinged telescopic plates, the lower end of the scissor-type telescopic mechanism being hinged to the drying frame of the clothes drying rack; a connecting component, used to connect the upper end of the scissor-type telescopic mechanism to the mounting frame, the connecting component comprising two movable connecting plates, the two movable connecting plates being hinged at the middle, one end of the two movable connecting plates being hinged to the upper end of the scissor-type telescopic mechanism, the other ends of the two movable connecting plates being respectively slidably hinged in the two waist-shaped holes, a stretching plate being hinged to each of the two movable connecting plates, and the other ends of the two stretching plates being hinged to the mounting frame.

[0006] The connection structure between the folding rack and the main machine slide rail is prone to shaking due to the large clearance, including during the drying process, lifting process, and encountering wind conditions. This shaking not only has an adverse effect on the stability of the structure, but also produces noise. In addition, when hanging clothes on one side of the drying rod, the tilt is large and it will collide with other accessories, which also poses a safety hazard. Utility Model Content

[0095] This embodiment provides an electric clothes drying machine, which includes a main machine, such as Figure 1-3 The folding telescopic frame 200 and the clothes drying rack are shown. The folding telescopic frame 200 is connected between the main unit and the clothes drying rack. The folding telescopic frame 200 can have a telescopic state and a folded state, so as to play the role of load-bearing suspension and maintaining balance in the rising and falling states of the clothes drying rack.

[0096] like Figure 1-3 As shown, this embodiment provides an installation structure of a foldable telescopic frame 200, and both upper and lower ends of the foldable telescopic frame 200 are connected between the main machine and the clothes drying rack through a connecting assembly 400. Of course, in other embodiments, the foldable telescopic frame 200 can be connected to the main machine only at the upper end through the connecting assembly 400 provided in this embodiment, or connected to the clothes drying rack only at the lower end through the connecting assembly 400 provided in this embodiment.

[0097] like Figure 1-3 As shown, the connection assembly 400 includes a track slider 401, an elastic fixing block 402 and a fixing pin 403. A connection part 1 is provided on both sides of the upper end and the lower end of the folding telescopic frame 200. The host and the clothes drying rack are provided with a track groove 2 matching the track slider 401.

[0098] like Figure 1-3 As shown in Figures 7 and 8, each connecting part 1 is provided with a mounting hole 11 matching with the elastic fixing block 402. The elastic fixing block 402 is interference-fitted in the mounting hole 11 in a non-rotatable manner. Both sides of the elastic fixing block 402 exceed the two opposite surfaces of the connecting part 1. The fixing pin 403 passes through the track slider 401 and the elastic fixing block 402 in sequence to connect the two. There is an interference fit between the fixing pin 403 and the elastic fixing block 402. The track slider 401 is provided with a receiving groove 3, and the connecting part 1 with the elastic fixing block 402 embedded is located in the receiving groove 3. The track slider 401 is embedded in the track groove 2 and can slide along the extension direction of the track groove 2.

[0099] In this way, the connection part 1 of the foldable telescopic frame 200 is hinged to the track slider 401, and the track slider 401 is slidably connected to the track groove 2, thereby providing an end connection mode for the foldable telescopic frame 200 to be folded and lifted.

[0100] By setting the elastic fixing block 402, the connection gap between the connecting part 1 of the folding telescopic frame 200 and the track slider 401 eliminates the assembly gap between the folding telescopic frame 200 and the track slider 401, thereby improving the stability of the assembly from the first dimension, reducing the possibility of shaking of the folding telescopic frame 200, and making the lifting and lowering of the clothes drying machine quieter.

[0101] When the connecting part 1 embedded with the elastic fixing block 402 is assembled in the receiving groove 3 of the track slider 401, the two sides of the elastic fixing block 402 exceed the two opposite surfaces of the connecting part 1. Therefore, the elastic fixing block 402 elastically contacts the groove wall of the receiving groove 3, which is not only beneficial to improve stability, but also beneficial to reduce the assembly gap. The second dimension reduces the possibility of shaking of the folding telescopic frame 200, making the lifting and lowering of the clothes drying machine quieter.

[0102] like Figure 4-5 As shown, the inner wall of the mounting hole 11 includes a plurality of first limiting surfaces a, and the elastic fixing block 402 is provided with a second limiting surface b matching the first limiting surface a; the first limiting surface a and the second limiting surface b cooperate to limit the elastic fixing block 402 from rotating in the mounting hole 11.

[0103] For the convenience of explanation, Figure 1-4 As shown, the track slider 401 between the folding telescopic frame 200 and the main machine is called the first track slider 401a, and the track slider 401 between the folding telescopic frame 200 and the clothes drying rack is called the second track slider 401b. The connection part 1 at the upper end of the folding telescopic frame 200 is called the upper connection part 1a, and the connection part 1 at the lower end of the folding telescopic frame 200 is called the lower connection part 1b. The track groove 2 on the main machine is called the upper track groove 2a, and the track groove 2 on the clothes drying rack is called the lower track groove 2b.

[0104] like Figure 1-2 As shown, a connector 100 is provided on both sides of the length of the main machine, and the connector 100 is provided with an upper track groove 2a extending along the width direction of the main machine. The connector 100 is a metal rigid component, thereby providing load-bearing strength.

[0105] like Figure 1-2 As shown, the connecting body 100 includes a horizontal plate e and two opposite vertical plates f extending downward from the horizontal plate e, and the inner walls of the vertical plates f form two oppositely spaced first vertical walls h1' of the upper track groove 2a. The lower edges of the two vertical plates f are relatively bent inward to form a first strip-shaped limiting wall h2', and the notch of the upper track groove 2a is formed between the first strip-shaped limiting walls h2' on both sides. Part of the horizontal plate e forms a first bottom limiting wall h3' away from the notch end.

[0106] like Figure 5 As shown, a first boss s1' matching the slot width of the corresponding upper track slot 2a is provided in the middle of the lower surface of the first track slider 401a, and a first strip-shaped recessed portion s2' is formed on both sides of the first boss s1'. The first boss s1' extends from the slot to the slot of the upper track slot 2a, and the first strip-shaped recessed portion s2' is restricted by the first strip-shaped limiting wall h2' to slide in the upper track slot 2a.

[0107] like Figure 1-2 As shown, the clothes drying rack is provided with a rod base 300 connected to a folding and telescopic frame 200. The folding and telescopic frame 200 is connected between the rod base 300 and the clothes drying rack through a connecting assembly 400. The rod base 300 is in a U-shaped structure and has a lower track groove 2b. Two oppositely spaced second vertical walls h1" of the lower track groove 2b are the two side walls of the rod base. An upper strip plate k and a lower strip plate g are provided on the inner side of each side wall, which are spaced up and down and extend along the length direction thereof. A notch of the lower track groove 2b is formed between the two opposite upper strip plates k of the two second vertical walls h1". The lower wall of the upper strip plate k is the second strip-shaped limiting wall h2" of the lower track groove 2b. The upper walls of the two opposite lower strip plates g of the two second vertical walls h1" together constitute the second bottom limiting wall h3" of the lower track groove 2b.

[0108] like Figure 5 As shown, a second boss s1" matching the slot width of the corresponding lower track groove 2b is provided in the middle of the upper surface of the second track slider 401b, and a second strip-shaped recessed portion s2" is formed on both sides of the second boss s1". The second boss s1" extends from the slot to the slot of the lower track groove 2b, and the second strip-shaped recessed portion s2" is restricted by the second strip-shaped limiting wall h2" to slide in the lower track groove 2b.

[0109] In summary, the track groove 2 includes two relatively spaced vertical walls, a bottom limiting wall away from the groove end and strip limiting walls on both sides of the groove end.

[0110] The track slider is provided with a boss s1 that matches the width of the slot of the corresponding track slot, and strip-shaped recessed portions s2 are formed on both sides of the boss. The boss s1 extends from the slot to the corresponding track slot 2, and the strip-shaped recessed portion s2 is limited by the strip-shaped limiting wall to slide in the track slot 2. In this way, the assembly gap in the width direction is further reduced, and the stability of the folding telescopic frame 200 in lifting and lowering is improved.

[0111] like Figure 4-5As shown, the upper end of the folding and telescopic frame 200 includes two crossed first-stage folding pieces 201. The upper connecting portion 1a is arranged at the upper end of the first-stage folding piece 201, and is further hinged to the connecting body 100 on the main machine through the connecting assembly 400. The lower end of the folding and telescopic frame 200 includes two crossed last-stage folding pieces 202, and the lower connecting portion 1b is arranged at the lower end of the last-stage folding piece 202, and is further hinged to the clothes drying rack through the connecting assembly 400.

[0112] The middle of the first-stage folding piece 201 is hinged to an upper hinge piece 203. The other ends of the two upper hinge pieces 203 are hinged to the middle of the connecting body 100 through a first fixing pin 403. The middle of the last-stage folding piece 202 is hinged to a lower hinge piece 204. The other ends of the two lower hinge pieces 204 are hinged to the middle of the clothes drying rack through a second fixing pin 403. These structures are conducive to the stability of the folding and telescopic rack 200.

[0113] like Figure 2 , 6 As shown, the surface of the upper rail slider 401 near the first bottom limiting wall h3' is provided with two first convex ridges L1 spaced relatively from each other. A concave bottom anti-friction area R1 is formed between the two first convex ridges L1. When the first convex ridge L1 contacts the first bottom limiting wall h3', a space is formed between the bottom anti-friction area R1 and the first bottom limiting wall h3'.

[0114] like Figure 3 As shown, the surface of the lower track slider 401 close to the second bottom limiting wall h3" is also provided with two first ridges L1 spaced apart from each other. A recess is formed between the two first ridges L1. The first ridges L1 act on the lower strip plate g of the lower track groove 2b.

[0115] like Figure 2 , 3 As shown in Figures 6 and 7, a second ridge L2 is provided on the strip-shaped recessed portion of the track slider 401. The second ridge L2 is less protruding than the boss s1. When the boss s1 extends from the notch to the corresponding track groove 2, the second ridge L2 is restricted by the strip-shaped limiting wall to slide in the track groove 2. The inner sides of the first ridge L1 and the second ridge L2 are both inclined surfaces that expand outward from the ridge end to the bottom of the ridge, thereby reducing the active area on the basis of improving stability and improving the sliding performance.

[0116] like Figure 2 , 3 As shown in FIG. 6 , the two sides of the track slider 401 include upper convex ribs M1 and lower convex ribs M2 spaced apart from each other, and a side anti-friction area R2 is formed between the upper convex ribs M1 and the lower convex ribs M2. The bottom anti-friction area R1 and the side anti-friction area R2 reduce the friction between the track slider 401 and the track groove 2, thereby making the sliding smoother and further playing a mute role.

[0117] The above is a detailed introduction to the installation structure of a folding telescopic rack and an electric clothes drying machine provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
