[0045] The present embodiment provides a stepless adjustment supporting foot for supporting devices such as furniture, office equipment, mechanical equipment, etc., which can realize adjustment of supporting height. As shown in Figures 1-7 The stepless adjustment supporting foot includes a movable foot 10, a bottom supporting foot 20, a clamping piece 30, a mounting piece 40, and an elastic piece 50. The movable foot 10 has a connecting portion 11. The bottom supporting foot 20 is provided with a mounting cavity 201 and an adjustment cavity 202 that are in communication with each other. The clamping piece 30 is arranged in the mounting cavity 201. The clamping piece 30 is provided with a lock release cavity 301 for the connecting portion 11. The mounting piece 40 and the elastic piece 50 are movably arranged in the adjustment cavity 202. The mounting piece 40 is connected with the clamping piece 30.

[0046] Further, as shown in Figure 3 The first end of the elastic piece 50 abuts against the inner wall of the adjustment cavity 202, and the second end abuts against the mounting piece 40. When the mounting piece 40 moves between the first position and the second position in the adjustment cavity 202, the elastic piece 50 expands and contracts accordingly. Specifically, when the mounting piece 40 moves to the first position in the adjustment cavity 202, the lock release cavity 301 is subjected to the force of the mounting cavity 201 in the radial direction and deforms, and the clamping piece 30 locks the connecting portion 11.

[0047] The stepless adjustment support foot provided by the embodiment is realized by the movement of the movable foot 10 relative to the bottom support foot 20, the clamping member 30 is arranged in the mounting cavity 201 of the bottom support foot 20, the mounting member 40 can change the position of the clamping member 30 relative to the bottom support foot 20, so that the locking and releasing cavity 301 of the clamping member 30 is contracted or expanded, thereby locking or releasing the connecting part 11. When the user removes the force on the mounting member 40, the elastic member 50 in the compressed state resets and releases the elastic potential energy, and when the mounting member 40 moves to the first position in the adjusting cavity 202, the locking and releasing cavity 301 is contracted and deformed under the action of the mounting cavity 201 in the radial direction, and the clamping member 30 locks the connecting part 11 to fix the position of the movable foot 10 relative to the bottom support foot 20; when the user pushes the mounting member 40 to compress the elastic member 50 and controls the mounting member 40 to move to the second position in the adjusting cavity 202, the mounting cavity 201 releases the force on the locking and releasing cavity 301 in the radial direction, and the locking and releasing cavity 301 expands and deforms, and the clamping member 30 releases the connecting part 11. At this time, the user can directly pull the movable foot 10 to adjust the distance between the movable foot 10 and the bottom support foot 20, thereby realizing stepless adjustment. In summary, the stepless adjustment support foot does not need to adjust the support height by rotating the movable support foot, the user controls the deformation of the clamping member 30 through the mounting member 40 and the elastic member 50 to quickly lock and release the connecting part 11, the efficiency of adjusting the support height is high, manpower is saved, and user experience is improved.

[0048] As shown in Figures 1-3 , the movable foot 10 further includes a sleeve part 12, the upper end of the connecting part 11 is fixedly connected with the sleeve part 12, the sleeve part 12 is sleeved on the outside of the bottom support foot 20, and the top of the sleeve part 12 is used for connecting or supporting the bottom of a furniture or the like.

[0049] As shown in Figures 1-3 , the connecting part 11 is arranged in a rod-shaped structure extending in the vertical direction. In the embodiment, the connecting part 11 is a screw rod, and the outer periphery of the screw rod is provided with external threads, thereby facilitating clamping and locking.

[0050] As shown in Figure 3 and Figure 5 , the bottom support foot 20 includes an inner cylinder part 21 and an outer cylinder part 22, the inner cavity of the inner cylinder part 21 defines the mounting cavity 201, and the inner cylinder part 21 is further provided with a movable cavity 203, the upper end of the movable cavity 203 is communicated with the mounting cavity 201, the lower end of the movable cavity 203 is communicated with the adjusting cavity 202, the outer cylinder part 22 is arranged around the outer periphery of the inner cylinder part 21, the adjusting cavity 202 is formed between the inner cylinder part 21 and the outer cylinder part 22, and the elastic member 50 and the mounting member 40 can be hidden in the adjusting cavity 202.

[0051] As shown in the embodiment, the inner cylinder part 21 and the outer cylinder part 22 are integrally formed and are made of metal alloy or plastic.

[0052] As shown in the embodiment,Figures 3-5 As shown, the clamping member 30 comprises a main body portion 31, at least two lock releasing portions 32 and a moving portion 33. The at least two lock releasing portions 32 are outwardly extended from the main body portion 31 and are spaced apart. The lock releasing cavity 301 is formed between the at least two lock releasing portions 32. The main body portion 31 is arranged in the mounting cavity 201. The moving portion 33 is extended from the main body portion 31 in a direction away from the lock releasing portions 32. The moving portion 33 is arranged in the active cavity 203. The end of the moving portion 33 is connected with the mounting member 40. In the embodiment, the lock releasing portions 32 are located at the upper end of the main body portion 31. The clamping member 30 comprises two lock releasing portions 32. The two lock releasing portions 32 are symmetrically and spaced apart. A separation groove 34 is formed between the two lock releasing portions 32. The separation groove 34 provides sufficient space for the deformation of the two lock releasing portions 32. Preferably, the separation groove 34 extends to the main body portion 31. The deformation space between the two lock releasing portions 32 is further expanded. The deformation range of the lock releasing cavity 301 is also larger.

[0053] For example, when the mounting member 40 is moved towards the first position, the lock releasing portions 32 are moved towards the mounting cavity 201. The inner wall of the mounting cavity 201 presses against the lock releasing portions 32. The lock releasing portions 32 are moved towards each other. The lock releasing cavity 301 is deformed to contract. The connecting portion 11 is gradually pressed. The movable leg 10 is locked. When the mounting member 40 is moved towards the second position, the lock releasing portions 32 are moved away from the mounting cavity 201. The lock releasing portions 32 are moved away from each other. The lock releasing cavity 301 is deformed to expand. The connecting portion 11 is released. The movable leg 10 is in a loose state.

[0054] For example, as shown in Figure 4 and Figure 5 The outer circumferential surface of the lock releasing portion 32 is provided with a pushing surface 322. The mounting cavity 201 is provided with a supporting surface 2011. When the clamping member 30 is moved towards the supporting surface 2011, the pushing surface 322 receives the supporting force of the supporting surface 2011 in the radial direction. The lock releasing portion 32 moves towards each other. The lock releasing cavity 301 is deformed to contract. Specifically, the radial dimension of the lock releasing portion 32 gradually increases from bottom to top to form the downwardly inclined pushing surface 322. The upper end of the mounting cavity 201 is formed with a gradually expanding structure with the radial dimension gradually increasing from bottom to top to form the upwardly inclined supporting surface 2011. Therefore, when the clamping member 30 is moved downwards or when the movable leg 10 is subjected to downward pressure, the pushing surface 322 presses against the supporting surface 2011. As the distance of downward movement or the downward load gradually increases, the supporting force of the supporting surface 2011 on the pushing surface 322 also gradually increases. The clamping force of the mounting cavity 201 on the lock releasing portion 32 also gradually increases. The connecting portion 11 is increasingly clamped. Therefore, the locking stability is excellent.

[0055] For example, as shown in Figure 2 , Figure 3 and Figure 5As shown, the stepless adjustment supporting foot further comprises locking blocks 60 arranged in the locking release cavity 301 and abutting against the inner wall of the locking release cavity 301; when the locking release cavity 301 is deformed to contract, the locking blocks 60 are driven to move towards the connecting portion 11 to abut against the connecting portion 11; when the locking release cavity 301 is deformed to expand, the locking blocks 60 are driven to move away from the connecting portion 11 to release the connecting portion 11.

[0056] Further, as shown in the figure, Figure 5 As shown, the inner wall of the locking release cavity 301 is provided with mounting positions 321 for the locking blocks 60. Specifically, the mounting positions 321 are provided as groove structures extending in the radial direction and penetrating the locking release portion 32, the locking blocks 60 are arranged in the mounting positions 321 and can slide in the mounting positions 321 relative to the locking release portion 32. Specifically, the locking blocks 60 are arranged in the mounting positions 321, and when the locking release cavity 301 is deformed to contract, the two locking blocks 60 are driven to slide in the corresponding mounting positions 321 and move close to each other.

[0061] Exemplarily, the main body portion 31 is made of rigid materials such as metal, and when the main body portion 31 extrudes the locking release portion 32, the locking release portion 32 expands and deforms outward in the radial direction.
