[0001] The utility model relates to the technical field of seat processing, in particular to a novel chair foot. Background Art
[0002] A chair is a piece of furniture for daily life, a kind of seat with a backrest and armrests. Modern chairs pursue beauty and fashion. Some chairs are no longer just seats, but are endowed with more technology to make people more convenient.
[0003] The chair legs in the prior art, such as the utility model patent document with authorization announcement number "CN219742295U" and patent name "A children's dining chair with cushioning and shock-absorbing function", discloses a chair leg, including a support plate, a support foot, a seat and a soft connecting belt, and also includes a shock-absorbing component and an adjustment component. The shock-absorbing component includes a guide rod, a guide block, a support spring, a shock absorber, a telescopic rod and a buffer spring, and the adjustment component includes a fixed plate, an adjustment rod, a base plate and a universal wheel.
[0004] The height of the seat in the above patent document is relatively fixed, and the user cannot adjust the relative vertical height of the seat according to his own needs, and cannot adapt to the needs of people of different heights. Utility Model Content
[0005] The purpose of the utility model is to propose a new type of chair leg in response to the deficiencies of the prior art, which is used to solve the technical problem mentioned in the background technology that the height of the chair seat of the prior art is relatively fixed, the user cannot adjust the vertical relative height of the chair seat according to his own needs, and cannot adapt to the use needs of people of different heights.
[0006] The above technical objectives of the utility model are achieved through the following technical solutions:
[0007] A new type of chair leg includes a hollow supporting leg, a connecting block is provided on the supporting leg, a screw is threadedly connected to the connecting block and the screw is coaxial with the supporting leg, a supporting block is provided at the end of the screw away from the connecting block, a hollow shielding column is slidably provided on the supporting leg and the shielding column is threadedly connected to the supporting block.
[0008] Working principle:
[0009] First, the support legs are installed under the seat plate. When the user needs to adjust the height of the seat plate, the user can drive the screw by rotating the support block. Under the action of the connecting block, the screw can be moved closer to or away from the support legs, thereby adjusting the height position of the seat plate.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] First, a connecting block and a screw rod are provided. Rotating the screw rod can make the supporting block at the end of the screw rod approach or move away from the connecting block, so that the height of the seat plate can be adjusted by adjusting the position of the screw rod on the connecting block.
[0012] Second, a shielding column is provided, which can prevent damage caused by external force colliding with the screw rod, and the shielding column can shield the screw rod and the connecting block to play a certain aesthetic role. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 The schematic diagram of the structure is to remove the blocking column;
[0015] Figure 3 It is a structural diagram of the connection block;
[0016] Figure 4 This is a schematic diagram of the structure of the shielding column.
[0017] Explanation of the accompanying drawings: supporting leg 1, connecting block 2, screw rod 3, supporting block 4, shielding column 5, placement groove 6, placement block 7, convex ridge 8, first internal thread 9, second internal thread 10, second external thread 11, anti-slip groove 12, groove 13. DETAILED DESCRIPTION
[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] Example:
[0020] like Figure 1 and Figure 2 As shown, a new type of chair leg includes a hollow supporting leg 1, a connecting block 2 is provided on the supporting leg 1, a placement groove 6 is opened on the supporting leg 1, a placement block 7 is fixedly provided on the connecting block 2 and the placement block 7 is clamped with the placement groove 6, the placement block 7 on the connecting block 2 can be clamped into the placement groove 6 through the placement groove 6, and plays a certain positioning role when installing the connecting block 2, a plurality of annular convex ridges 8 are fixedly provided on the outer wall of the connecting block 2 and the convex ridges 8 are abutted against the inner wall of the supporting leg 1, when the connecting block 2 is installed on the supporting leg 1, the convex ridges 8 are squeezed by the inner wall of the supporting leg 1, so that the convex ridges 8 and the inner wall of the supporting leg 1 are tightly connected, thereby preventing the connecting block 2 from falling off the supporting leg 1.
[0021] like Figure 2 and Figure 3As shown, the connecting block 2 is threadedly connected with a screw rod 3 and the screw rod 3 is coaxial with the supporting leg 1. The connecting block 2 is provided with a first internal thread 9. The screw rod 3 is threadedly connected to the connecting block 2 via the first internal thread 9. The screw rod 3 and the first internal thread 9 can be used to move the screw rod 3 closer to or farther away from the supporting leg 1, thereby adjusting the height of the seat plate, and the screw rod 3 and the connecting block 2 can be locked via the threaded connection relationship.
[0022] like Figure 2 and Figure 4 As shown, a support block 4 is provided at the end of the screw rod 3 away from the connecting block 2, a hollow shielding column 5 is slidably provided on the support leg 1 and the shielding column 5 is threadedly connected to the support block 4, a second internal thread is provided on the side wall of the support block close to the screw rod, a second external thread is provided on the inner wall of the shielding column, the shielding column is threadedly connected to the support block through the cooperation of the second external thread and the second internal thread, and the second internal thread 10 and the second external thread 11 can facilitate the connection between the shielding column 5 and the support block 4.
[0023] like Figure 1 and Figure 2 As shown, the threaded connection direction between the connecting block 2 and the screw rod 3 is opposite to the threaded connection direction between the supporting block 4 and the shielding column 5. When adjusting the distance between the supporting block 4 and the connecting block 2, the screw rod 3 can be driven to rotate by rotating the shielding column 5.
[0024] like Figure 1 As shown, the shielding column 5 is provided with a plurality of anti-skid grooves 12 , and the end of the support block 4 away from the screw rod 3 is provided with a plurality of grooves 13 . The anti-skid grooves 12 can reduce the slipping of the shielding column 5 when the user rotates it.
[0025] Working principle:
[0026] First, the installer installs the support leg 1 at the bottom of the seat seat. When the user needs to adjust the height of the seat seat, the user can rotate the shielding column 5. Since the threaded connection direction of the shielding column 5 and the support block 4 is opposite to the threaded connection direction of the screw 3 and the connecting block 2, rotating the shielding column 5 can drive the screw 3 to rotate. The rotation of the screw 3 can make the screw 3 approach or move away from the support leg 1, which makes it convenient for the user to adjust the distance between the support block 4 and the support leg 1, and finally adjust the height distance between the support block 4 and the seat seat.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
