[0034] Please refer to Figure 1 and Figure 2 , the present disclosure provides a telescopic bed frame, including: a first support frame 100, a second support frame 200, a connecting rod 300, and a telescopic assembly 400.

[0035] The first support frame 100 and the second support frame 200 are arranged opposite to each other; in some embodiments, the first support frame 100 and the second support frame 200 are mirror-symmetrical. The shapes of the first support frame 100 and the second support frame 200 can both be set to but not limited to the Figure 1 boat shape as shown. The first support frame 100 is fixed (for example, screwed) with a first bed foot 110, and the second support frame 200 is fixed (for example, screwed) with a second bed foot 210. The first bed foot 110 and the second bed foot 210 are used to contact the ground to support the telescopic bed frame of the present disclosure.

[0036] The connecting rod 300 is disposed between the first support frame 100 and the second support frame 200; in some embodiments, the shortest distance between any point on the axis of the connecting rod 300 and the first support frame 100 is equal to the shortest distance between this point and the second support frame 200 (that is, the first support frame 100, the connecting rod 300, and the second support frame 200 are arranged at equal intervals in sequence).

[0037] The telescopic assembly 400 is hinged to the first support frame 100, the second support frame 200, and the connecting rod 300; in some embodiments, the number of the telescopic assemblies 400 is more than one; in one implementation, the number of the telescopic assemblies 400 is two, one telescopic assembly 400 is hinged to one end of the connecting rod 300, and the other telescopic assembly 400 is hinged to the other end of the connecting rod 300, so as to ensure the structural stability of the telescopic bed frame. The telescopic assembly 400 includes a first telescopic rod 410 and a second telescopic rod 420. The first telescopic rod 410 includes a first end 411 and a second end 412 of the first telescopic rod which are opposite to each other; the first end 411 of the first telescopic rod is hinged to the first support frame 100, so that the first end 411 of the first telescopic rod can rotate relative to the first support frame 100 with the hinge point as the rotation axis. The second telescopic rod 420 includes a first end 421 and a second end 422 of the second telescopic rod which are opposite to each other; the first end 421 of the second telescopic rod is hinged to the second support frame 200, so that the first end 421 of the second telescopic rod can rotate relative to the second support frame 200 with the hinge point as the rotation axis. The second end 412 of the first telescopic rod is hinged to the connecting rod 300, and the second end 422 of the second telescopic rod is hinged to the connecting rod 300, so that the second end 412 of the first telescopic rod can rotate relative to the connecting rod 300 with the hinge point as the rotation axis, and the second end 422 of the second telescopic rod can rotate relative to the connecting rod 300 with the hinge point as the rotation axis. Furthermore, the distance between the first support frame 100 and the connecting rod 300 and the distance between the second support frame 200 and the connecting rod 300 can both be adjusted.

[0038] For the telescopic bed frame provided by the present disclosure, by arranging the two ends of the first telescopic rod 410 to be respectively hinged to the first support frame 100 and the connecting rod 300, and arranging the two ends of the second telescopic rod 420 to be respectively hinged to the second support frame 200 and the connecting rod 300, the distance between the first support frame 100 and the connecting rod 300 can be changed by the rotation of the first telescopic rod 410, and the distance between the second support frame 200 and the connecting rod 300 can be changed by the rotation of the second telescopic rod 420. Thus, the user can expand or reduce the distance between the first support frame 100 and the second support frame 200 by rotating the first telescopic rod 410 and / or the second telescopic rod 420, and further realize the telescoping of the bed frame. Therefore, the present disclosure solves the technical problem in the related art that the size of the bed frame is fixed and cannot be adjusted according to the user's usage requirements and usage environment, thus being inconvenient for the user to use.

[0039] In some embodiments of the present disclosure, refer to Figures 1-3 , the telescopic assembly 400 further includes a fastener 430 (which can be a bolt). The connecting rod 300 is provided with a first through hole 11, the second end 412 of the first telescopic rod is provided with a second through hole 12, and the second end 422 of the second telescopic rod is provided with a third through hole 13; the fastener 430 is in clearance fit with the first through hole 11 and the second through hole 12, so that the first telescopic rod 410 can rotate relative to the connecting rod 300 around the fastener 430 and the second telescopic rod 420 can rotate relative to the connecting rod 300 around the fastener 430; the fastener 430 passes through the third through hole 13 and is fixedly connected to the connecting rod 300 (which can be fixed by screwing or by interference fit), so as to ensure that the connecting rod 300 does not move relative to the fastener 430 during the rotation of the first telescopic rod 410 or the second telescopic rod 420, which is convenient for users. In one implementation manner of this embodiment, the fastener 430 sequentially passes through the second through hole 12, the third through hole 13, and the first through hole 11, or the fastener 430 sequentially passes through the third through hole 13, the second through hole 12, and the first through hole 11.

[0040] In some embodiments of the present disclosure, refer to Figure 3 , the first support frame 100 is fixed (for example, screwed) with a first connecting member 51, and the first support frame 100 and the first connecting member 51 do not move relative to each other. The first connecting member 51 is provided with a first connecting member through hole 52, and the first end 411 of the first telescopic rod is provided with a fourth through hole 14. A first fixing member 81 (which can be a bolt) sequentially passes through the fourth through hole 14 and the first connecting member through hole 52. The first fixing member 81 is in clearance fit with the fourth through hole 14 so that the first telescopic rod 410 can rotate relative to the first connecting member 51 around the first fixing member 81. The first fixing member 81 passes through the first connecting member through hole 52 and is fixedly connected to the first connecting member 51 (which can be fixed by screwing or by interference fit), so as to ensure that the first connecting member 51 does not move relative to the first fixing member 81 during the rotation of the first telescopic rod 410, which is convenient for users.

[0041] In still other embodiments of the present disclosure, refer to Figure 3, the second support frame 200 is fixed (e.g., screwed) with a second connecting member 53, and there is no relative movement between the second support frame 200 and the second connecting member 53. The second connecting member 53 is provided with a through hole 54 of the second connecting member, and the first end 421 of the second telescopic rod is provided with a fifth through hole 15. The second fixing member 82 (which can be a bolt) sequentially passes through the fifth through hole 15 and the through hole 54 of the second connecting member. The second fixing member 82 is in clearance fit with the fifth through hole 15 so that the second telescopic rod 420 can rotate relative to the second connecting member 53 around the second fixing member 82. The second fixing member 82 passes through the through hole 54 of the second connecting member and is fixedly connected to the second connecting member 53 (which can be fixed by screwing or by interference fit), thereby ensuring that during the rotation of the second telescopic rod 420, the second connecting member 53 will not move relative to the second fixing member 82, which is convenient for users to use.

[0042] In some embodiments of the present disclosure, please refer to Figures 1-3 , one end of the first connecting member 51 close to the first end 411 of the first telescopic rod is provided with a first limiting structure; the first limiting structure is used to limit the first telescopic rod 410 during the rotation of the first telescopic rod 410 relative to the first connecting member 51 around the first fixing member 81. In one implementation manner of this embodiment, the first limiting structure includes a first limiting member 61 (which can be a bolt) and more than one first limiting through hole 71 provided in the first connecting member 51. The first end 411 of the first telescopic rod is provided with a sixth through hole 16. The first limiting member 61 passes through the sixth through hole 16 and any one of the first limiting through holes 71 to limit the first telescopic rod 410 (i.e., limit the rotation of the first telescopic rod 410). Thus, after the user rotates the first telescopic rod 410 to a preset position (i.e., after adjusting the distance between the first support frame 100 and the second support frame 200), the rotation of the first telescopic rod 410 can be limited by inserting the first limiting member 61 into the sixth through hole 16 and any one of the first limiting through holes 71, and then the telescopic bed frame can be used.

[0043] In some other embodiments of the present disclosure, please refer to Figures 1-3, one end of the second connecting member 53 close to the first end 421 of the second telescopic rod is provided with a second limiting structure; the second limiting structure is used to limit the second telescopic rod 420 during the rotation of the second telescopic rod 420 relative to the second connecting member 53 around the second fixing member 82. In one implementation manner of this embodiment, the second limiting structure includes a second limiting member 62 (which can be a bolt) and more than one second limiting through hole 72 opened in the second connecting member 53. A seventh through hole 17 is opened at the first end 421 of the second telescopic rod. The second limiting member 62 passes through the seventh through hole 17 and any one of the second limiting through holes 72 to limit the second telescopic rod 420 (that is, to limit the rotation of the second telescopic rod 420). Thus, after the user rotates the second telescopic rod 420 to a preset position (that is, after adjusting the distance between the first support frame 100 and the second support frame 200), the rotation of the second telescopic rod 420 can be limited by inserting the second limiting member 62 into the seventh through hole 17 and any one of the second limiting through holes 72, and then the telescopic bed frame can be used.
