[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figures 1 to 4 The utility model belongs to a simple T-shaped bed with lifting and adjustment, which has a simple structure and includes a single support tube body arranged on the left and right sides, an upper frame 12 and a lower frame 13 connected to the support tube body. The upper frame 12 is connected to the support tube body through an upper surrounding tube connector 4, and the lower frame 13 is connected to the support tube body through a second-layer connector 10. The upper frame 12 and the upper surrounding tube connector 4 can be detachably installed, and the lower frame 13 and the second-layer connector 10 can also be detachably installed; the support tube body is composed of a telescopic structure; the upper and lower frames are installed on the support tube body, and the telescopic movement of the support tube body drives the upper and lower frames to move up and down. The single support tube bodies on both sides are installed on the lower seat body 11 and placed on the ground.

[0026] The telescopic structure is composed of an outer sleeve 1, an inner lifting tube 8 inserted into the outer sleeve 1, a lifting switch group 9 fixed at the lower end of the inner lifting tube 8, a shifting pull plate 6 fixed at the upper end of the inner lifting tube 8, and a pull rope 7 connected and installed between the lifting switch group 9 and the shifting pull plate 6. The pull rope 7 and the inner lifting tube 8 form a whole. When the pull rope 7 moves upward, the inner lifting tube 8 also moves upward.

[0027] The upper end of the lifting inner tube 8 is inserted into one end of the upper surrounding tube connector 4, and the two are plugged into each other.

[0028] The outer tube wall of the outer sleeve 1 is provided with a hollow 101 for the two-layer connector 10 to move up and down. The two-layer connector 10 is fixedly installed on the outer tube wall of the lifting inner tube 8. Since the hollow 101 is provided on the tube wall of the outer tube 1, the two-layer connector 10 fixed on the lifting inner tube 8 can slide arbitrarily in the hollow 10; countless gear jacks 102 are evenly spaced on the side wall of the outer tube 1.

[0029] The lifting switch group 9 is provided with a latch 904 inserted into the gear position socket 102 .

[0030] like Figure 6 As shown, the lifting switch group 9 is composed of a covering shell 902 arranged on both sides, a first slider 905 and a second slider 906 arranged in the covering shell 902, an upper and lower compression spring 901 connected to the first slider 905, and a left and right compression spring 903 connected to the second slider 906, one end of the left and right compression spring 903 is fixed on the covering shell 902, and the other end is connected to the second slider 906.

[0031] like Figure 6 and Figure 7 As shown, the latch 904 connects the first slider 905 and the second slider 906; the latch 904 can be extended and retracted in the gear position socket 102 under the action of the left and right compression springs 903. Since the second slider 906 is wedge-shaped and the first slider 905 is 7-shaped, the inclined surfaces of the two sliders are aligned, and the latch 904 can move up and down in the hole of the first slider 905, that is, one end of the latch 904 is fixed on the second slider 906, and the other end passes through the first slider 905; therefore, when the first slider 905 is subjected to an upward pulling force, it drives the first slider 905 to move upward, so that the latch 904 also deviates upward in the hole of the first slider 905, and then under the action of the left and right compression springs 903, the latch 904 is retracted from the gear position socket 102 to change the gear position and is inserted into another gear position socket, thereby achieving the purpose of shifting the gear position socket. The insertion of the latch 904 into the gear position socket 102 relies on the spring recovery of the left and right springs 903 to push the latch 904 into the gear position socket 102 .

[0032] The upper surrounding tube connector 4 is connected to two locks 5 via two lock torsion springs 3 . The two locks 5 are installed on the outer wall of the upper surrounding tube connector 4 , while the two lock torsion springs 3 are installed inside the upper surrounding tube connector 4 .

[0033] like Figure 5 As shown, the second lock 5 is U-shaped. In the normal state, the second lock 5 embraces the upper outer wall of the lifting inner tube 8 and just presses the gear pull plate 6. When the gear pull plate 6 is to be pulled, the second lock 5 is first pushed away from the lifting inner tube wall, and then the gear pull plate 6 can be pulled.

[0034] like Figure 8 As shown, when in use, the upper frame 12 and the lower frame 13 are covered with cloth, and the upper frame 12 and the lower frame can be moved upward as a whole under the pull of the gear pull plate 6, and can be operated unilaterally with one hand.

[0035] The lower end of the lifting inner tube 8 of the utility model is a free end, and the upper end is inserted and installed on the upper surrounding tube connector 4. The gear pull plate 6 drives the pull rope 7 together with the lifting inner tube 8 to rise or fall inside the outer tube 1.
