The specific embodiment of the invention is as follows:

example (b): as shown in fig. 1 to 8, the present invention provides a detachable seating furniture stand comprising a support leg 1, a bushing 2 and a support member 3. The supporting legs 1 and the supporting pieces 3 are metal pieces, and the bushings 2 are made of plastic.

As shown in FIG. 4, the supporting leg 1 has a top end and a bottom end in its height direction, and a plug 4 extending horizontally outward is provided on a side wall of the top end of the supporting leg 1. As shown in fig. 5, the liner 2 has a head end and a tail end along its length direction, the liner 2 is sequentially divided into an insertion section 5 and an abutting section 6 along the head end to the tail end, and the diameter of the abutting section 6 of the liner 2 is larger than that of the insertion section 5. Meanwhile, the end wall of the tail end of the bush 2 is provided with a second slot 8, and the second slot 8 extends along the length direction of the bush 2. As shown in fig. 2-4, the supporting member 3 has a leg 9 extending horizontally outward, and the leg 9 is provided with a first slot 7 extending along the length direction thereof. Specifically, support piece 3 in this scheme includes cross-connected first support body and second support body, and the head and the tail both ends of first support body and the head and the tail both ends of second support body all constitute above-mentioned stabilizer blade 9. The insertion section 5 of the bush 2 is horizontally inserted into the first slot 7 of the supporting leg 9, the plug connector 4 is horizontally inserted into the second slot 8 of the bush 2, and the opposite outer walls of the supporting leg 1 and the supporting leg 9 abut against the outer walls of the bush 2 and two sides of the abutting section 6 and clamp the abutting section 6.

Above-mentioned supporting structure adopts the connected mode of pegging graft, and it is more firm in the connected mode of sheet metal component that it compares, can not warp. And because the plug connector 4 and the first slot 7 on the supporting leg 9 extend along the horizontal direction, the parallelism is easy to control, and the plug connection is more convenient. After the insertion, the top groove wall of the first slot 7 is pressed on the plug connector 4 due to the gravity or the pressure of the upper cushion, and the support leg 9 is difficult to rock relative to the plug connector 4. Meanwhile, the support structure further reduces the gap between the plug connector 4 and the wall of the first slot 7 by arranging the bush 2. And because bush 2 is the plastics material, avoid rocking sound between stabilizer blade 9 and the plug connector 4 after long-time the use, play the effect of silence. And bush 2 is greater than the diameter of inserting section 5 in the diameter that leans on section 6, and plug connector 4 inserts supporting leg 1 and stabilizer blade 9 relative outer wall and bush 2 and the both sides outer wall that leans on section 6 offset and press from both sides tightly and lean on section 6 during second slot 8 also make and no longer leave the clearance between stabilizer blade 9 and the supporting leg 1, have avoided stabilizer blade 9 and supporting leg 1 direct contact to lead to long-time use after sounding.

And to facilitate insertion of the insertion section 5 of the bush 2 into the first socket 7 on the foot 9. As shown in fig. 4 and fig. 6, in this embodiment, the insertion section 5 is divided into a reduced diameter portion 11 and an equal diameter portion 10 along the head-to-tail direction of the connection section, the diameter of the insertion section 5 at the reduced diameter portion 11 is gradually reduced from the head end to the tail end, and the diameter of the insertion section 5 at the equal diameter portion 10 is the same as the tail end diameter of the reduced diameter portion 11. Since the diameter of the insertion section 5 at the reduced diameter portion 14 is gradually reduced from the head end to the tail end, the insertion section 5 can be conveniently inserted into the first slot 7. The diameter of the constant diameter portion 10 is the same as the diameter of the tail end of the reduced diameter portion 11, so that the problem of shaking caused by an overlarge gap between the insertion section 5 and the first slot 7 can be avoided.

At the same time, in order to further eliminate the gap between the bush 2 and the support leg 1. Supporting leg 1 is the cylinder structure in this scheme, and the tail end wall of bush 2 is inside sunken arcwall face, supporting leg 1 and stabilizer blade 9 relative outer wall and bush 2 with lean on the both sides outer wall that leans on section 6 and offset and press from both sides tightly when leaning on section 6, the outer wall laminating of arcwall face and supporting leg 1. Because the tail end wall of bush 2 is inside sunken arcwall face for even supporting leg 1 also can laminate with the outer wall of supporting leg 1 for the cylinder structure, not only the structure is more firm, and the outward appearance is also more pleasing to the eye. Of course, if the support leg 1 is of a quadrangular prism structure, the end wall of the tail end of the bushing 2 can also be a flat plane.

In addition, as shown in fig. 4, when the relative outer walls of the supporting leg 1 and the supporting foot 9 and the outer walls of the bush 2 and the two sides of the abutting section 6 abut and clamp the abutting section 6, the top end surface of the supporting leg 1 is flush with the top end surface of the abutting section 6 and the top end surface of the supporting piece 3. Because the top end face of the supporting leg 1 is flush with the top end face of the abutting section 6 and the top end face of the supporting piece 3, the problem that a subsequent cushion is not smooth after being installed on a support formed by the supporting leg 1 and the supporting leg 9 is solved, and the cushion is convenient to install.

And to achieve locking and unlocking of the positions between the plug 4, the bush 2 and the foot 9. As shown in fig. 4-8, the sidewall of the inserting member 4 is provided with a groove 12, the supporting leg 9 is provided with a through hole 13, an inserting block 14 is inserted into the through hole 13, and an elastic member acts on the inserting block 14. Specifically, the elastic member in this embodiment is a spring 16, and a fixing cover 22 is covered on the outer wall of the supporting leg 9, and the insertion block 14 is partially exposed outside the supporting leg 9 and is located inside the fixing cover 22 and covered by the fixing cover 22. One end of the spring 16 abuts against the inner wall of the fixed cover 22, and the other end of the spring 16 abuts against the insert block 14.

Meanwhile, a third slot 15 is arranged on the side wall of the insert block 14, and the third slot 15 is partially exposed out of the support leg 9. The foot 9 is further provided with a slider 17, the slider 17 being slidable with respect to said foot 9 and being inserted into or withdrawn from the third slot 15 of said insert 14. The slider 17 is also located inside the fixed cover 22 and covered by the fixed cover 22. The sliding block 17 has a head end and a tail end along the length direction thereof, wherein the head end of the sliding block 17 is adjacent to the insert block 14. In order to avoid the slide block 17 from being inclined in the sliding process, the top end surface of the slide block 17 is abutted against the inner wall of the fixed cover 22 to form a limit. The head end of the slide block 17 is provided with a diameter-variable part 18, and the thickness of the slide block 17 on the diameter-reduced part 11 is gradually increased from the head end to the tail end of the locking piece.

When the insert 4, the bush 2 and the foot 9 need to be assembled. Firstly, the sliding block 17 is slid to enable the sliding block 17 to be inserted into the third slot 15 of the insertion block 14, and as the thickness of the sliding block 17 on the diameter-changing part 18 is gradually increased from the head end to the tail end of the locking piece, the sliding block 17 can be forced to move in the hole depth direction of the through hole 13 in the process of being inserted into the third slot 15, so that the insertion block 14 can completely withdraw from the groove 12 on the insertion piece 4 to complete unlocking. The bush 2 and the plug 4 can be freely inserted into the first slot 7 of the leg 9 for assembly.

In order to facilitate the pushing of the sliding block 17, a sliding groove 19 and a positioning groove 20 are formed on the fixed cover 22, the sliding groove 19 extends along the length direction of the third slot 15, a push rod 21 is arranged on the sliding block 17, and the push rod 21 penetrates through the sliding groove 19 and is exposed out of the fixed cover 22. The slide block 17 can be inserted into or withdrawn from the third slot 15 by pushing the push rod 21. In the present embodiment, the width of the sliding block 17 is smaller than the width of the third slot 15. The fixing cover 22 is further provided with a positioning groove 20, the positioning groove 20 extends along the width direction of the third slot 15, and when the push rod 21 drives the slide block 17 to move to the communication position between the slide groove 19 and the positioning groove 20, the slide block 17 is inserted into the third slot 15 and the insertion block 14 exits the groove 12. Since the width of the middle sliding block 17 is smaller than the width of the third slot 15, the sliding block 17 can move along the width direction of the third slot 15 after being inserted into the third slot 15. When the push rod 21 drives the slide block 17 to move to the communication position between the slide groove 19 and the positioning groove 20, the slide block 17 is inserted into the third slot 15 and the insert block 14 is already made to exit the groove 12. Then only the push rod 21 needs to be pushed to slide along the positioning slot 20. The push rod 21 receives the spacing of the groove wall of the positioning groove 20, and can not move along the length direction of the third slot 15, the slide block 17 can be directly inserted into the third slot 15, the jack can not be inserted into the groove 12, the user does not need to press the push rod 21 all the time, and the user can vacate two hands to take and assemble the support leg 1, the support piece 3 and the bush 2.

And at this time, the insertion block 14 moves a certain distance in the hole depth direction of the through hole 13, and the spring 16 is in a compressed state.

After the assembly is completed, the user only needs to push the push rod 21 in the reverse direction to make the slide block 17 exit the third slot 15. At this time, after the restoring force of the spring 16 is inserted among the plug connector 4, the bushing 2 and the support leg 9, the spring 16 acts on the insertion block 14 to force the insertion block 14 to press the bushing 2 to deform and extrude the bushing 2 into the groove 12 on the side wall of the plug connector 4, so that the insertion block 14 can be matched with the inner wall of the groove 12 to clamp the bushing 2, and the plug connector 4, the support leg 9 and the bushing 2 are locked. The structure can realize the locking and unlocking among the plug connector 4, the support leg 9 and the bush 2 without screwing screws. And the restoring force of the spring 16 continuously acts on the insert 14 without worrying about the insert 14 coming out of the groove 12. Meanwhile, the bush 2 is clamped in the groove 12 to fill the gap between the insert block 14 and the groove 12, and the shaking cannot occur.

The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the invention, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the invention.
