[0045] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0046] As Figures 1 - 8 shown, the embodiments of the present utility model provide a novel telescopic folding bed, including: a support frame, a bed frame, a bed cloth 7, a locking assembly, and other parts.

[0047] Among them, the bed frame includes a fixed bed frame and a movable bed frame. The fixed bed frame is foldably arranged on the support frame. Through holes with protruding parts are formed through opposite sides of the fixed bed frame. A movable bed frame is slidably arranged in the fixed bed frame. A placement hole is formed through the movable bed frame. A locking component is arranged through the placement hole and the through hole to realize the locking and fixation between the fixed bed frame and the movable bed frame. The bed cloth 7 covers the fixed bed frame and the movable bed frame and is detachably connected to the fixed bed frame and the movable bed frame.

[0048] Figure 1 A bed frame structure is shown. Specifically, the fixed bed frame includes a first fixed bed frame 12 and a second fixed bed frame 14. The first fixed bed frame 12 and the second fixed bed frame 14 are arranged adjacent to each other, and the first fixed bed frame 12 and the second fixed bed frame 14 are respectively of a frame structure. The movable bed frame includes a first movable bed frame 11 and a second movable bed frame 13. The first movable bed frame 11 is slidably arranged in the first fixed bed frame 12, and the second movable bed frame 13 is also slidably arranged in the second fixed bed frame 14. By relative sliding, the elongation or contraction function of the bed frame is realized. The first movable bed frame 11 and the second movable bed frame 13 are respectively in the shape of "[".

[0049] Figure 1 At the same time, a support frame structure is also shown. Specifically, the support frame includes a first support frame 21, a second support frame 22, and a third support frame 23. A connecting plate 3 is arranged on the second support frame 22. The connecting plate 3 is fixedly connected to the second support frame 22 by rivets. The first fixed bed frame 12 and the second fixed bed frame 14 are correspondingly hinged on the connecting plate 3 of the second support frame 22, that is, the first fixed bed frame 12 and the second fixed bed frame 14 are hinged to the second support frame 22 through the connecting plate 3, so as to realize the folding function of the first fixed bed frame 12 and the second fixed bed frame 14. Folding support rods 4 are arranged between the first movable bed frame 11 and the first support frame 21 and between the second movable bed frame 13 and the third support frame 23. The first support frame 21 is hinged to the first movable bed frame 11 through the folding support rod 4 and can be folded into the first movable bed frame 11. Similarly, the third support frame 23 is hinged to the second movable bed frame 13 through the folding support rod 4 and can be folded into the second movable bed frame 13.

[0050] Figures 4 - 6 The locking component of the folding bed is shown, including a support block 61, a follower chuck 62, a spring 63, and a pin 64. Among them, the support block 61 is placed in the movable bed frame. Specifically, as Figure 3 shown, a placement hole 111 substantially the same shape as the support block 61 is formed through the first movable bed frame 11. The support block 61 is placed in the placement hole 111. As Figure 5As shown, one end of the support block 61 is a hanging hook-shaped structure, and a pin hole 611 is penetrated through the opposite other end. A pin 64 is penetrated through the pin hole 611. A groove 612 is formed at the bottom of the support block 61. One end of the spring 63 is placed in the groove 612, and the other end is connected to the bottom of the placement hole 111 on the first movable bed frame 11. As Figure 6 shown, the follower clamping seat 62 is arranged in parallel with the support block 61 and is located inside the first fixed bed frame 12. As Figure 4 shown, a slot-shaped opening is penetrated through the middle position of the follower clamping seat 62, and the slot-shaped opening corresponds to the pin hole 611. More specifically, the slot-shaped opening includes a large slot opening 621 and a small slot opening 622, and the large and small slot openings are adjacent and communicated. As Figure 2 shown, channels are penetrated through the opposite two side surfaces along the length direction of the first fixed bed frame 12. The channels are substantially wavy, and the wavy shape is composed of a plurality of wave crests 121 and a plurality of wave troughs 122. The wave crests 121 and the wave troughs 122 are arranged at intervals and extend along the length direction of the first fixed bed frame 12. Among them, the height of the small slot opening 622 is less than or equal to the height of the wave trough 122, and the heights of the large slot opening 621 and the placement hole 111 are greater than or equal to the height of the wave crest 121. As Figure 6 shown, the pin 64 penetrates through the support block 61, the first movable bed frame 11, the follower clamping seat 62 and the first fixed bed frame 12 in sequence.

[0051] During use, as Figure 6 shown, when the stretching and locking function of the bed frame is to be realized, the first movable bed frame 11 is stretched outwards. The first movable bed frame 11 drives the support block 61 to move outwards. The support block 61 drives the pin 64, and the pin 64 drives the follower clamping seat 62 to move outwards together. During the outward movement, the pin 64 is located in the large slot opening 621. When the pin 64 is at the wave trough 122, the spring 63 is compressed; when the pin 64 follows the first movable bed frame 11 to move to the wave crest 121, under the action of the elastic force of the spring 63, the pin 64 is clamped at the wave crest 121, so as to realize the locking function of the first movable bed frame 11 and the first fixed bed frame 12; the first movable bed frame 11 is continuously stretched until the first movable bed frame 11 is stretched to a suitable position, and the position of the bed frame is fixed through the cooperation of the pin 64 and the wave crest 121; when the shortening function is to be realized, the first movable bed frame 11 is stretched along the stretching direction until it is pulled to the end of one tail of the channel. At this time, the pin 64 is in the wave trough 122, the spring 63 is compressed, and the first movable bed frame 11 is stretched to the longest; then the first movable bed frame 11 is pushed inwards along the shortening direction. At this time, the follower clamping seat 62 remains stationary under the action of the friction force with the inner wall of the first fixed bed frame 12. As the first movable bed frame 11 shortens, as Figures 7 - 8As shown, the pin 64 moves within the trough 122 along the shortening direction until the pin 64 is located within the small notch 622. The pin 64 located within the small notch 622 keeps the spring 63 in a compressed state all the time. Therefore, driven by the first movable bed frame 11, the clamping seat 62 follows the pin 64 and can move all the way to the other end head position of the channel. At this time, the first movable bed frame 11 is shortened to the shortest. Repeating this way, the telescopic locking function of the bed frame is realized.

[0052] Similarly, the locking function between the second movable bed frame 13 and the second fixed bed frame 14 is realized in the same way as that between the first movable bed frame 11 and the first fixed bed frame 12.

[0053] Furthermore, fixing rods 5 are provided on the first support frame 21, the second support frame 22 and the third support frame 23 respectively. The fixing rods 5 ensure the stability of the first support frame 21, the second support frame 22 and the third support frame 23.

[0054] Even further, in this embodiment, the folding support rod 4 includes a folding support short rod 41 and a folding support long rod 42. One end of the folding support short rod 41 is hinged to the first movable bed frame 11, and the other end is hinged to the first support frame 21. Similarly, one end of the folding support long rod 42 is hinged to the first movable bed frame 11, and the other end is hinged to the first support frame 21.

[0055] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
