[0044] refer to Figure 1 - Fig.12 The present embodiment provides an assembled bed frame structure, including a bed frame composed of a support rod 1 and a crossbar 2, a beam rod 3 supported by an inner beam frame, and a vertical rod 4 constituting a bed surface support; wherein the assembly connection between the various components is as follows: the support rod 1 and the beam rod 3, the beam rod 3 and the vertical rod 4, the crossbar 2 and the vertical rod 4 are connected and fixed by plugging or buckling; the support rod 1 is a mid-section hinged foldable type, a support leg 5 is provided at the mid-section hinge 11 and bed legs 6 are provided at both ends for support; fixed seats 12 are provided at both ends of the support rod 1, and the bed legs 6 are rotatably connected thereto On the fixing seat 12, the fixing seat 12 is provided with an insertion port 121 for plugging with the cross bar 2; the fixing seat 12 is provided with a locking piece, and the bed leg 6 includes a first locking position and a second locking position. When the bed leg 6 is rotated to form a bed leg 6 support, the first locking position and the locking piece are locked so that the bed leg 6 is locked in a supporting state, and in this locked state, the plug-in end 24 of the cross bar 2 is locked in the insertion port 121 at the second locking position. The bed frame assembled by this assembly connection method does not require screw assembly and fixing, and is safe, firm and reliable.

[0045] Steps to assemble the bed frame:

[0046] Step 1, complete the assembly of the two support rods 1 on both sides of the bed frame. In this embodiment, the support rod 1 is a mid-section hinged foldable type, which is divided into left and right support rods 1, which are hinged on both sides by a connecting piece to form a foldable form, and a support leg 5 is fixed in the middle position of the connecting piece. When one of the left and right support rods 1 is unfolded relative to the other, the support leg 5 is unfolded at the same time by the rotation of the connecting piece, forming a central support function.

[0047] Step 2, complete the assembly of the bed legs 6 and the crossbar 2 to form a bed frame when the support rod 1 is in the unfolded state. In this embodiment, the bed legs 6 are rotatably hinged to the end of the support rod 1 by a rotating seat 7, and the two ends of the support rod 1 are rotatably connected to the bed legs 6. The rotating seat 7 is hinged to the fixed seat 12 of the support rod 1 by a rivet 71, and a first locking position is set on the side where the rotating seat 7 is connected to the fixed seat 12, and a second locking position is set on the side where the rotating seat 7 is connected to the bed legs 6. During assembly, the plug-in end 24 of the crossbar 2 is first aligned with the plug-in interface 121 of the fixed seat 12. After the plug-in of the crossbar 2 is completed, the bed legs 6 are rotated to unfold to form a support. When the bed legs 6 are rotated to complete the unfolding and form a support with the support rod 1, the locking member is locked in the first locking position, so that the bed legs 6 no longer rotate. At the same time, the bed legs 6 lock the plug-in end 24 of the crossbar 2 in the plug-in interface 121 in the second locking position in this locked state, limiting the movement of the crossbar 2 to disengage along the plug-in interface 121.

[0048] Step 3, on the basis of the bed frame, complete the assembly of the beam 3. The connection structure between the support rod 1 and the beam 3 includes a card slot 13 provided on the rod body of the support rod 1 and a card 31 provided at the end of the beam 3; the card slot 13 and the card 31 form a card connection.

[0049] Step 4, after the bed frame frame completes the assembly of the beam 3, the vertical rod 4 is assembled, the connection structure between the beam 3 and the vertical rod 4 or the cross bar 2 and the vertical rod 4 includes a snap-in 23 with an elastic clip arranged on the rod body of the beam 3 or the cross bar 2, and a clamping part 41 with a clamping hole arranged at the end of the vertical rod 4; the clamping part 41 is inserted along the insertion direction until the elastic clip is clamped into the clamping hole to form a clamping connection.

[0050] The above completes the overall assembly of the bed frame.

[0051] In step 2, the locking cooperation structure of the support rod 1 and the bed leg 6 is as follows: the locking member includes a lock core 122 arranged in the fixed seat 12, a lock hole 72 arranged on the rotating seat 7 and an unlocking member; wherein the lock hole 72 arranged on the rotating seat 7 is the first locking position; the lock core 122 has a certain deformation amount for locking or unlocking it with the lock hole 72, and a button 123 is arranged on the outer side of the fixed seat 12 relative to its lock core 122 as an unlocking member.

[0052] Specifically, a gap 124 is set in the fixed seat 12, and the side of the rotating seat 7 connected to the fixed seat 12 is placed in the gap 124 and has a certain amount of rotation in the gap 124; a clearance hole connected to the gap 124 is set on the outer side of the fixed seat 12 relative to its lock core 122, which is used to make way for the pressing of the button 123; in the locked state, the lock core 122, the lock hole 72 and the clearance hole are coaxially arranged, and the lock core 122 passes through the lock hole 72 and the clearance hole for pressing and cooperating with the button 123.

[0053] In this embodiment, the lock core 122 includes an elastic member and a ball head, and the ball head can be extended and retracted under the action of the elastic member. The locking operation is that when the rotating seat 7 rotates with the bed leg 6 until the bed leg 6 is in a supporting state, the lock hole 72 on the rotating seat 7 corresponds to the lock core 122, and the lock hole 72 provides a space for the lock core 122 to pop out, so that the ball head pops out and gets stuck at the lock hole 72 under the action of the elastic member to form a lock, thereby preventing the bed leg 6 from rotating back.

[0054] By setting the gap 124, the rotational cooperation between the rotating seat 7 and the fixed seat 12 is hidden in the fixed seat 12, which not only achieves the overall aesthetics, but also plays a role in protecting the rotating seat 7. In order to realize the unlocking function of the button 123, a clearance hole is set on the fixed seat 12. When the lock hole 72 and the lock core 122 correspond to the lock core 122 and the lock core 122 pops out, the lock core 122 further pops out of the clearance hole to cooperate with the button 123. In order to make the lock core 122 pressed back to unlock, the button 123 is provided with a pressing protrusion 125 corresponding to the clearance hole. When pressing the lock core 122, the lock core 122 is further pressed to ensure that it is retracted until it is unlocked from the lock hole 72. When retracting the legs, press the button first, press the ball head into the lock hole 72 to unlock it, and then rotate the bed legs 6.

[0055] In step 2, the locking matching structure of the support rod 1 and the cross bar 2 is as follows: the plug-in end 24 of the cross bar 2 is provided with two limiters 22, which are plugged into and contact the two end surfaces of the fixing seat 12 to limit the front and rear position of the cross bar 2. The second locking position is set on the end surface of the support rod 1 against which the rotating seat 7 is connected to the fixing seat 12 after rotation; the second locking position is set as a protrusion 73 with a certain tilt angle; a groove 21 is set at the plug-in end 24 of the cross bar 2, and the groove 21 is set below the plug-in end 24 and is adapted to the position of the protrusion 73 when rotating.

[0056] When assembling the cross bar 2, first insert the plug-in end 24 of the cross bar 2 into the plug-in port 121 of the fixing seat 12, and pass the end limiter 22 close to the end face of the cross bar 2 through the plug-in port 121 to abut against the end face of one side of the fixing seat 12, and the other limiter 22 is relatively abutted against the end face of the other side of the fixing seat 12 to form a limit, so that the limiter 22 limits the front and rear movement of the cross bar 2 relative to the support rod 1. The function of the limiter 22 is, on the one hand, to limit the lateral movement of the cross bar 2, and on the other hand, to position the position of the positioning groove 21 , so that the groove 21 under the cross bar 2 can be aligned with the protrusion 73 on the rotating seat 7 of the upper bed leg 6; when the cross bar 2 is plugged in and the bed leg 6 is rotated for assembly, the rotating bed leg 6 is linked to the rotating seat 7, and the protrusion 73 on the rotating seat 7 supports the cross bar 2, first pushing the cross bar 2 outward and upward, so that the limit piece 22 on the outer side of the cross bar 2 and the upper side of the cross bar 2 are in close contact with the fixing seat 12, and then the protrusion 73 is inserted into the groove 21, further limiting the forward and backward movement and the up and down movement of the cross bar 2, and when the bed leg 6 is locked, the locking and fixing of the cross bar 2 is achieved.

[0057] Furthermore, the position-limiting member 22 is a position-limiting plastic member, which can play a buffering role. When the bed frame shakes, it can buffer the collision force of the connection part between the cross bar 2 and the support bar 1 to avoid collision and noise. The position-limiting setting of the groove 21 and the protrusion 73 includes two square grooves 21 and two protrusions 73, which play a better role in position-limiting and fixing. The protrusion 73 is set to have a certain inclination angle, which can transition to the position of the groove 21 during rotation and insertion, and at the same time fine-tune the horizontal position so that the protrusion 73 can be better inserted into the groove 21.

[0058] In step 3, the provided clamping structure of the beam 3 includes a clamping slot 13 and a card 31. The clamping slot 13 is welded on the support rod 1, and the card 31 is welded on the beam 3. The clamping width of the clamping slot 13 changes gradually along its insertion direction to form a slope 131, which is gradually tightened along the insertion direction. When the beam 3 is pressed down, the card 31 is gradually clamped with the clamping slot 13 along the insertion direction. The slope 131 of the clamping slot 13 is inclined at a certain angle, and the card 31 is set with a certain elasticity, so that the beam 3 will not be unable to be pressed down because the groove 21 is too tight when it is pressed down.

[0059] The assembly method of the bed frame structure proposed in this embodiment does not involve a screw locking structure during the entire assembly process, does not require screw tools during assembly, is simple and fast to assemble, and does not cause incorrect assembly of parts. It can be quickly assembled and disassembled without the need for screws, and ensures that the bed frame structure is safe, firm, and reliable.

[0060] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
