DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] In order to solve the technical problem that workers need to squat and bend down to rotate the adjusting rod of the floor cabinet, and need to always pay attention to the rising or lowering height of the floor cabinet during rotation, which is inconvenient to operate, the utility model provides a push-type lifting cabinet foot.

[0031] See also Figure 1 , Figure 1 Schematic diagram of the structure of the push-type lifting cabinet foot in one embodiment of the utility model. The push-type lifting cabinet foot includes a supporting mechanism 1, an anti-drop mechanism 2, and an upward push mechanism 3.

[0032] See also Figure 1-Figure 4 The support mechanism 1 includes a base 11, a sleeve 12, a plug rod 13 and a top plate 14. The lower end of the sleeve 12 is fixed to the base 11, and the lower end of the plug rod 13 is slidably inserted in the sleeve 12. A plurality of first ratchet teeth 131 are formed on one side wall of the plug rod 13, and a plurality of second ratchet teeth 132 are formed on the other side wall of the plug rod 13. The upper end of the plug rod 13 is fixed to the top plate 14;

[0033] The anti-drop mechanism 2 includes a pawl 21 and a first spring 22, one end of the pawl 21 is hinged to the base 11, and the other end of the pawl 21 is used to be inserted between two adjacent first ratchet teeth 131, and both ends of the first spring 22 are connected to the pawl 21 and the base 11 respectively;

[0034] Specifically, each first ratchet tooth 131 has an inclined side wall and a vertical side wall, the inclined side wall is inclined relative to the length direction of the insertion rod, the vertical side wall is perpendicular to the length direction of the insertion rod, and the vertical side wall is located below the inclined side wall. Therefore, when the insertion rod 13 descends relative to the pawl 21, since the vertical side wall is located below the inclined side wall, the vertical side wall on the insertion rod 13 will first contact the pawl 21, so that the insertion rod 13 cannot descend under the obstruction of the pawl 21. On the contrary, when When the insertion rod 13 rises relative to the pawl 21, since the vertical side wall is located below the inclined side wall, the inclined side wall on the insertion rod 13 will first contact the pawl 21, and the inclined side wall of the insertion rod 13 will push the pawl 21 to rotate outward, so that the insertion rod 13 can rise, thereby ensuring that the insertion rod 13 can only rise and cannot fall under normal conditions through the anti-fall mechanism 2, and the function of the first spring 22 is to make the other end of the pawl 21 tightly clamped between the two adjacent first ratchet teeth 131 to prevent the pawl 21 from loosening.

[0035] The pushing mechanism 3 includes an elastic telescopic member 31, a first pedal 32 and a second spring 33. The fixed end of the elastic telescopic member 31 is hinged to the base 11, and the movable end of the elastic telescopic member 31 is used to be inserted between two adjacent second ratchet teeth 132. The first pedal 32 is fixed to the fixed end of the elastic telescopic member 31, and the two ends of the second spring 33 are respectively connected to the first pedal 32 and the base 11.

[0036] Specifically, the inclination direction of the second ratchet tooth 132 is the same as that of the first ratchet tooth 131, and each second ratchet tooth 132 has an inclined side wall and a vertical side wall. The inclined side wall is inclined relative to the length direction of the insertion rod, and the vertical side wall is perpendicular to the length direction of the insertion rod, and the vertical side wall is located below the inclined side wall.

[0037] When in use, the bottom of the installed floor cabinet is facing upwards, and then a plurality of push-type lifting cabinet feet are fixed to the bottom surface of the floor cabinet respectively. The specific fixing method is to fix the top plate 14 to the bottom surface of the floor cabinet, and then flip the floor cabinet over and reset it so that the base 11 of each push-type lifting cabinet foot contacts the ground, and then selectively adjust the height of some push-type lifting cabinet feet according to the flatness of the floor cabinet. The specific adjustment method is to step on the first pedal 32 to drive the elastic telescopic member 31 to rotate clockwise (such as Figure 5), since one end of the elastic telescopic member 31 is stuck between two adjacent second ratchet teeth 132, and when one end of the telescopic member 31 rises, the elastic telescopic member 31 will contact the vertical side walls of each second ratchet tooth 132, and thus will act upward on the plug rod 13. When the plug rod 13 rises, it can push the pawl 21 to rotate outward, so that the pawl 21 cannot prevent the plug rod 13 from rising, and the plug rod 13 drives the top plate 14 and a corner of the floor cabinet to rise. Afterwards, one end of the elastic telescopic member 31 continues to rotate clockwise to disengage from the second ratchet teeth 132. At this time, the foot is released, and under the action of the restoring force of the second spring 33, the first pedal 32 moves up (such as Figure 6 ), thereby driving the elastic member 31 to rotate counterclockwise. When the elastic member 31 moves downward relative to the insertion rod 13, when the elastic member 31 contacts each second ratchet tooth 132, it will first contact the inclined side wall of each second ratchet tooth 132, and the inclined side wall of the second ratchet tooth 132 will push the elastic member 31 to contract, so that the elastic member 31 can smoothly rotate to the initial position (such as Figure 6 ), then, continue to step on the first pedal 32 to raise the insertion rod 13, the top plate 14 and one corner of the floor cabinet, and repeat this cycle until one corner of the floor cabinet rises to a suitable height.

[0038] The technical solution provided by the utility model can prevent the insertion rod 13 from falling through the cooperation of the pawl 21 and the first ratchet 131, so that the top plate 14 can be kept at a certain height, and the insertion rod 13 can be driven to rise through the second ratchet 132 by stepping on the first pedal 32, and the first pedal 32 can be reset by the second spring 33, so that the height of the foot can be adjusted by stepping on it. When adjusting the height of the floor cabinet, the worker does not need to squat or bend down to rotate the adjustment rod of the foot, which greatly improves the convenience of use.

[0039] In one embodiment, see Figure 1-Figure 3 A first clearance hole 121 and a second clearance hole 122 are formed on the side wall of the sleeve 12. The first clearance hole 121 is used for the ratchet 21 to pass through, and the second clearance hole 122 is used for the elastic telescopic member 31 to pass through.

[0040] In one embodiment, see Figure 1 and Figure 2 The base 11 includes a bottom plate 111 and a first fixed block 112, the lower end of the sleeve 12 is fixed to the bottom plate 111, the first fixed block 112 is fixed to the bottom plate 111, and one end of the pawl 21 is hinged to the first fixed block 112; the anti-drop mechanism 2 also includes a second pedal 23, the second pedal 23 is fixed to the pawl 21, and the two ends of the first spring 22 are respectively connected to the second pedal 23 and the first fixed block 112.

[0041] In one embodiment, see Figure 1 and Figure 2 The base 11 also includes a second fixed block 113, which is fixed to the bottom plate 111, and the two ends of the second spring 33 are fixedly connected to the first pedal 32 and the second fixed block 113 respectively; the elastic telescopic member 31 includes a sleeve 311, a slider 312, a third spring 313, a connecting rod 314 and a clamping block 315, the slider 312 is slidably arranged in the sleeve 311, the third spring 313 is built in the sleeve 311, one end of the third spring 313 abuts against the inner wall of the sleeve 311, and the other end of the third spring 313 abuts against the slider 312, the connecting rod 314 is hinged to the second fixed block 113, one end of the connecting rod 314 is fixedly connected to the slider 312, and the other end of the connecting rod 314 is fixedly connected to the first pedal 32, one end of the clamping block 315 is fixed to the sleeve 311, and the other end of the clamping block 315 is used to be clamped between two adjacent second ratchet teeth 132.

[0042] When the locking cam 315 is in the unlocking state, the locking cam 315 is in the unlocking state, and the locking cam 315 is in the unlocking state.

[0043] In one embodiment, see Figure 1-Figure 4 The inner cavity of the sleeve 311 is cylindrical, the shape of the slider 312 is cylindrical, and the sleeve 311 can rotate relative to the slider 312. A lever 316 is fixed to the sleeve 311, and the contact surface between the block 315 and the second ratchet 132 is an inclined surface 3151. When the lever 316 is located above the sleeve 311, the inclined surface 3151 is set downward (such as Figure 3 ), when the lever 316 is located below the sleeve 311, the inclined surface 3151 is arranged upward (such as Figure 4 ), when in use, the lever 316 is normally set upward (such as Figure 3), when the foot steps on the first pedal 32, the block 315 moves upward, thereby driving the insertion rod 13 to rise. When the height of the foot needs to be lowered, the lever 316 is rotated to the bottom of the sleeve 311. At this time, the inclined surface 3151 of the lever 316 is set upward (such as Figure 4 ), then, press the second pedal 23 to disengage the pawl 21 from the first ratchet tooth 131. At this time, the insertion rod 13 will drop. When it drops to a suitable height, the second pedal 23 is released to make the pawl 21 contact with the first ratchet tooth 131 again to prevent the insertion rod from continuing to move downward. When the insertion rod 13 drops, when each second ratchet tooth 132 contacts the inclined surface 3151 of the block 315, since the inclined surface 3151 of the block 315 is set upward, each second ratchet tooth 132 will contact the inclined surface 3151, thereby pushing the block 315 to move outward via the inclined surface 3151. Therefore, when the lever 316 rotates to the bottom of the sleeve 311, the inclined surface 3151 of the block 315 faces upward, thereby failing to prevent the insertion rod 13 from dropping. The height of the foot can be lowered by pressing the second pedal 23.

[0044] In one embodiment, see Figure 1 The top plate 14 is provided with a plurality of fixing holes 141 , so as to facilitate fixing the top plate 14 to the bottom surface of the floor cabinet.

[0045] In one embodiment, see Figure 1 A mounting block 15 is fixed on the top plate 14 , and a nut joint 151 is fixed on the mounting block 15 . The nut joint 151 can be used to install a T-line or a decorative panel.

[0046] In one embodiment, see Figure 1 The inner cavity of the sleeve 12 is in the shape of an elongated quadrangular prism, and the insertion rod 13 is in the shape of an elongated quadrangular prism.

[0047] In one embodiment, see Figure 1 The first pedal 32 is provided with a friction groove to prevent slipping.

[0048] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail: when in use, the bottom of the installed floor cabinet is facing upwards, and then a plurality of push-type lifting cabinet feet are fixed to the bottom surface of the floor cabinet respectively. The specific fixing method is to fix the top plate 14 to the bottom surface of the floor cabinet, and then flip the floor cabinet over and reset it so that the base 11 of each push-type lifting cabinet foot contacts the ground, and then selectively adjust the height of some push-type lifting cabinet feet according to the flatness of the floor cabinet. The specific adjustment method is to step on the first pedal 32 to drive the elastic telescopic member 31 to rotate clockwise (such as Figure 5), since one end of the elastic telescopic member 31 is stuck between two adjacent second ratchet teeth 132, when one end of the elastic telescopic member 31 rises, it will act on the plug rod 13 upward, and when the plug rod 13 rises, it can push the pawl 21 to rotate outward, so that the pawl 21 cannot prevent the plug rod 13 from rising, and the plug rod 13 drives the top plate 14 and a corner of the floor cabinet to rise, and then, one end of the elastic telescopic member 31 continues to rotate clockwise to disengage from the second ratchet teeth 132, and the foot is released at this time. Under the restoring force of the second spring 33, the first pedal 32 moves up (such as Figure 6 ), thereby driving the elastic member 31 to rotate counterclockwise. When the elastic member 31 moves downward relative to the insertion rod 13, when the elastic member 31 contacts each second ratchet tooth 132, it will first contact the inclined side wall of each second ratchet tooth 132, and the inclined side wall of the second ratchet tooth 132 will push the elastic member 31 to contract, so that the elastic member 31 can smoothly rotate to the initial position (such as Figure 6 ), then, continue to step on the first pedal 32 to raise the insertion rod 13, the top plate 14 and one corner of the floor cabinet, and repeat this cycle until one corner of the floor cabinet rises to a suitable height.

[0049] The technical solution provided by the utility model can prevent the insertion rod 13 from falling through the cooperation of the pawl 21 and the first ratchet 131, so that the top plate 14 can be kept at a certain height, and the insertion rod 13 can be driven to rise through the second ratchet 132 by stepping on the first pedal 32, and the first pedal 32 can be reset by the second spring 33, so that the height of the foot can be adjusted by stepping on it. When adjusting the height of the floor cabinet, the worker does not need to squat or bend down to rotate the adjustment rod of the foot, which greatly improves the convenience of use.
