They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0025] refer to Figures 1 to 7 , the utility model embodiment discloses:

[0026] A combined sofa bed comprises a transverse sofa assembly 1 arranged transversely and a longitudinal sofa assembly 2 arranged longitudinally on one side of the transverse sofa assembly 1. A telescopic mounting frame 3 is slidably arranged on the transverse sofa assembly 1 in the longitudinal direction, a mattress assembly is detachably arranged on the telescopic mounting frame 3, and a receiving cavity 4 is provided on the longitudinal sofa assembly 2 for placing the mattress assembly removed from the telescopic mounting frame 3; the longitudinal sofa assembly 2 has a receiving cavity 4 for placing the mattress assembly, and when it is necessary to convert the sofa form into a bed form, the telescopic mounting frame 3 can be slid out of the transverse sofa assembly 1, and then the mattress assembly can be taken out of the receiving cavity 4, and the mattress assembly can be installed on the telescopic mounting frame 3, and the sofa is converted into a bed form.

[0027] In one embodiment, the telescopic mounting frame 3 includes a group of longitudinal support rods 301, and the mattress assembly includes a mattress seat frame 5, on which a mattress is installed, and both ends of the mattress seat frame 5 are provided with downward-opening clamping grooves 6, and the clamping grooves 6 are adapted to the longitudinal support rods 301 so as to be clamped on the longitudinal support rods 301 at both ends of the mattress seat frame 5. When installing the mattress assembly, the mattress seat frame 5 is controlled to be placed on the telescopic mounting frame 3 from top to bottom, and the clamping grooves 6 are aligned with the longitudinal support rods 301, so that the longitudinal support rods 301 slide into the clamping grooves 6, and installation is achieved.

[0028] As shown in the figure, at least one limiting groove 7 is provided on the longitudinal support rod 301, and at least one limiting block 8 is provided on the mattress frame 5 and located on the inner wall of the clamping groove 6. When the mattress frame 5 is clamped on the longitudinal support rod 301, the limiting block 8 is embedded in the limiting groove 7 to limit the mattress frame 5 from sliding relative to the longitudinal support rod 301 in the longitudinal direction, thereby preventing the mattress frame 5 from sliding and disengaging from the longitudinal support rod 301.

[0029] In another embodiment, a locking device is provided between the longitudinal support rod 301 and the mattress frame 5 to limit the mattress frame 5 from sliding in the vertical direction and detaching from the longitudinal support rod 301. The locking device includes a limit rod 9. A first locking hole 10 is provided on the side wall of the longitudinal support rod 301. A second insertion hole 11 corresponding to the first locking hole 10 is provided on the mattress frame 5. The second insertion hole 11 is communicated with the clamping groove 6 so that when both ends of the mattress frame 5 are clamped on the longitudinal support rod 301, the limit rod 9 penetrates into the second insertion hole 11 and penetrates into the first locking hole 10. When the longitudinal support rod 301 slides into the clamping groove 6, the limit rod 9 is controlled to penetrate into the second insertion hole 11 and then into the first locking hole 10. At this time, the mattress frame 5 can be limited from moving in the vertical direction and detaching from the longitudinal support rod 301.

[0030] The mattress seat frame 5 is provided with a mounting seat 12, the limiting rod 9 is slidably provided on the mounting seat 12, and an elastic member 13 is provided in the mounting seat 12, and the elastic member 13 applies a force to the limiting rod 9 to extend into the clamping groove 6 or to prevent it from extending out of the clamping groove 6; specifically, Figure 5As shown, the elastic member 13 is a compression spring, which is sleeved on the limit rod 9, and a top boss is provided on the side wall of the limit rod, and the two ends of the compression spring respectively resist the top boss and the mounting seat 12, so that the limit rod 9 maintains the movement tendency of extending into the clamping groove 6; and when the user needs to remove the mattress seat frame 5, the user pulls the limit rod 9, so that the limit rod 9 overcomes the elastic force of the compression spring and extends outward, and the limit rod 9 is disengaged from the first locking hole 10, and no longer restricts the displacement of the mattress seat frame 5, and the mattress seat frame 5 can be removed.

[0031] A mounting hole 14 for mounting a pull ring is provided at one end of the limiting rod 9. The pull ring is mounted on the limiting rod 9 through the mounting hole 14. The user can pull the pull ring to drive the limiting rod 9 to move, which is convenient for the user to operate.

[0032] The longitudinal sofa assembly 2 includes a longitudinal base 201 and a longitudinal seat frame 202 disposed on the longitudinal base 201. The accommodating cavity 4 is opened on the longitudinal base 201 and the opening faces upward. The longitudinal seat frame 202 can slide / flip relative to the longitudinal base 201 to close / open the accommodating cavity 4. Specifically, in this embodiment, the longitudinal seat frame 202 is flipped to control the longitudinal seat frame 202 to close / open the accommodating cavity 4. Figure 7 As shown, a connecting rod mechanism is arranged between the longitudinal seat frame 202 and the longitudinal base 201, and the connecting rod mechanism includes a first connecting rod 203 arranged on the longitudinal base 201, and a second connecting rod 204 arranged on the longitudinal seat frame 202, and the first connecting rod 203 is hinged at both ends with a first hinged rod 205 and a second hinged rod 206, and the other ends of the first hinged rod 205 and the second hinged rod 206 are hinged at both ends of the second connecting rod 204, respectively. The longitudinal seat frame 202 is controlled to flip over by cooperating with the first connecting rod 203, the second connecting rod 204, the first hinged rod 205 and the second hinged rod 206, and the structure is simple.

[0033] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
