Therefore, it cannot be understood as a limitation on this application.

[0033] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0034] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other.

[0035] The inventors of this application have discovered that some existing seat support legs are equipped with a color-changing indicator to remind users when the seat is in a supported or unsupported state. However, this color-changing indicator is generally located near the bottom of the support leg, making it difficult for passengers to observe. The embodiments of this application provide a support leg for a seat that at least addresses this technical problem.

[0036] Please refer to Figures 1 to 5. The support legs provided in the embodiment of the present application include an outer tube 1, an inner tube 2, an adjusting plug 3 and an upper cover 4; the inner tube 2 and the outer tube 1 are slidably connected, and the bottom of the inner tube 2 is used to support on a fixed foundation; the adjusting plug 3 includes a connected body 31 and a push rod 32, the body 31 is fixedly connected to the inner tube 2, the body 31 is movably connected to the outer tube 1, and the body 31 has a tendency to move downward relative to the outer tube 1, and the push rod 32 extends vertically upward away from one end of the body 31; the upper cover 4 is arranged on the top of the outer tube 1, and a sliding block 41 is provided in the upper cover 4. The sliding block 41 has a tendency to move horizontally toward the push rod 32, and a first indicator mark and a second indicator mark are provided on the sliding block 41. A display window 42 for exposing the first indicator mark or the second indicator mark is opened on the upper cover 4.

[0037] When the supporting leg is in the supporting state, the inner tube 2 pushes the main body 31 and the push rod 32 upward, and the push rod 32 pushes the sliding block 41 to move until the first indicator mark is exposed in the display window 42; when the supporting leg is in the non-supporting state, the main body 31 and the push rod 32 move downward relative to the outer tube 1, and the sliding block 41 moves toward the push rod 32 until the second indicator mark is exposed in the display window 42.

[0038] It should be noted that the fixed base can be the ground, the base of a car or other fixed objects; one end of the push rod 32 is connected to the main body 31, and the other end of the push rod 32 extends upward and toward the sliding block 41; the first indicator mark and the second indicator mark are set at the top of the sliding block 41, the first indicator mark is used to indicate that the support leg is in a supporting state, and the second indicator mark is used to indicate that the support leg is in a non-supporting state.

[0039] By fixedly connecting the main body 31 of the adjusting plug 3 to the inner tube 2 and movably connecting it to the outer tube 1, a sliding block 41 provided with a first indicator mark and a second indicator mark is set in the upper cover 4, and the upper cover 4 is set on the top of the outer tube 1; when the support leg is in a supporting state, the inner tube 2 drives the main body 31 and the push rod 32 to move upward, and the push rod 32 moves upward and pushes the sliding block 41 to move until the first indicator mark is exposed in the display window 42; and when the support leg is in a non-supporting state, the main body 31 drives the push rod 32 to move downward relative to the outer tube 1, and the sliding block 41 moves toward the push rod 32 until the second indicator mark is exposed in the display window 42. Since the first indicator mark or the second indicator mark is exposed through the display window 42 opened in the upper cover 4, it is convenient for the occupant to observe the state of the seat.

[0040] A first elastic member 43 is disposed in the upper cover 4 . The first elastic member 43 is connected to the sliding block 41 , so that the sliding block 41 tends to move toward the push rod 32 .

[0041] In this embodiment, the first elastic member 43 is a spring, which is arranged in the horizontal direction. One end of the spring is connected to the inner wall of the upper cover 4, and the other end is connected to the sliding block 41, so that the sliding block 41 has a tendency to move horizontally toward the push rod 32.

[0042] Furthermore, an inclined surface 411 is provided at one end of the sliding block 41 close to the push rod 32 , and the push rod 32 is used to push the sliding block 41 through the inclined surface 411 until the first indication mark is exposed in the display window 42 .

[0043] When the supporting leg is in the supporting state, the inner tube 2 drives the main body 31 and the push rod 32 to move upward, the push rod 32 moves upward and pushes the inclined surface 411 of the sliding block 41, so that the sliding block 41 moves until the first indication mark is exposed in the display window 42; and when the supporting leg is in the non-supporting state, the main body 31 drives the push rod 32 to move downward relative to the outer tube 1, the push rod 32 gradually moves away from the inclined surface 411 of the sliding block 41, and the sliding block 41 moves toward the push rod 32 under the action of the first elastic member 43 until the second indication mark is exposed in the display window 42.

[0044] In this embodiment, the first indicator mark is a green mark, and the second indicator mark is a red mark.

[0045] When a green mark is displayed at the display window 42 , it indicates that the supporting leg is in a supporting state, and when a red mark is displayed at the display window 42 , it indicates that the supporting leg is in a non-supporting state.

[0046] Of course, it is understandable that in other embodiments, the first indicator mark and the second indicator mark are not necessarily color marks, but can also be shape marks or text marks, as long as they can distinguish whether the supporting leg is in a supporting state or a non-supporting state.

[0047] The regulating plug 3 further includes a connecting portion 33 , which is disposed above the body 31 and fixedly connected to the outer tube 1 . The body 31 and the connecting portion 33 are movably connected to enable the body 31 to move upward relative to the connecting portion 33 when subjected to force.

[0048] It should be pointed out that the main body 31 can move vertically relative to the connecting portion 33. When the inner tube 2 pushes the main body 31 and the push rod 32 upward, the main body 31 moves upward relative to the connecting portion 33. The connecting portion 33 serves to limit the main body 31 in the horizontal direction, thereby ensuring the stability of the vertical movement of the main body 31.

[0049] The supporting leg also includes a protective member 5 connected to the connecting portion 33. The protective member 5 is provided with a positioning block 51. The outer tube 1 is provided with a positioning hole 11 that cooperates with the positioning block 51. The connecting portion 33 is fixedly connected to the outer tube 1 through the mutual cooperation between the positioning block 51 and the positioning hole 11.

[0050] In this embodiment, the positioning block 51 is protruded from the protective member 5 toward the outer tube 1, and the connecting portion 33 is connected to the protective member 5 by a fastener 9, which can be a bolt or a screw; when the positioning block 51 is inserted into the positioning hole 11, the positioning block 51 and the positioning hole 11 cooperate with each other, and the connecting portion 33 is relatively fixed to the outer tube 1 when the positioning block 51 and the positioning hole 11 cooperate with each other.

[0051] A second elastic member 52 is provided between the protective member 5 and the body 31 . The second elastic member 52 allows the body 31 to have a tendency to move downward relative to the outer tube 1 .

[0052] The second elastic member 52 is a spring, which is arranged vertically. One end of the spring is connected to the positioning block 51 , and the other end is connected to the body 31 , so that the body 31 has a tendency to move downward relative to the outer tube 1 .

[0053] In addition, the supporting leg also includes a button 6, a gear member 7 and a third elastic member 8. The button 6 is hinged to the main body 31. The gear member 7 is connected to the bottom of the button 6. A plurality of gear holes 21 are opened on the inner tube 2 along its own length direction. The gear member 7 is used to cooperate with one of the gear holes 21; the third elastic member 8 is connected to the top of the button 6, so that the button 6 has a tendency to move away from the main body 31.

[0054] It should be pointed out that the button 6 is hinged to the main body 31 near its middle part, the shift member 7 is connected to the bottom of the button 6, the third elastic member 8 is a spring, one end of the third elastic member 8 is connected to the top of the button 6, and a groove 34 is provided on the surface of the main body 31 facing the button 6, and the other end of the third elastic member 8 abuts against the groove 34.

[0055] When the gear position of the inner tube 2 needs to be adjusted, the top of the button 6 is pressed toward the main body 31. The button 6 rotates, and the gear member 7 can be disengaged from the matching gear hole 21. At this time, the inner tube 2 is slid relative to the outer tube 1 until the other gear hole 21 is opposite to the gear member 7. At this time, the button 6 is released. Under the action of the third elastic member 8, the button 6 rotates in the opposite direction, thereby driving the gear member 7 to cooperate with the other gear hole 21 to complete the gear adjustment.

[0056] The outer tube 1 is provided with a notch 12 for the clamping end 71 to pass through, the shift member 7 has a clamping end 71, and the body 31 is provided with a through hole 311 for the clamping end 71 to pass through. The height of the notch 12 in the length direction of the outer tube 1 is greater than the thickness of the clamping end 71 in the length direction of the outer tube 1.

[0057] The notch 12 is opened at the bottom of the outer tube 1, and the clamping end 71 extends toward the inner tube 2 through the through hole 311 and the notch 12 and is clamped in the gear hole 21. Since the height of the notch 12 in the length direction of the outer tube 1 is greater than the thickness of the clamping end 71 in the length direction of the outer tube 1, the difference between the height of the notch 12 in the length direction of the outer tube 1 and the thickness of the clamping end 71 in the length direction of the outer tube 1 is the space margin for the vertical movement of the inner tube 2 relative to the outer tube 1. The vertical movement of the main body 31 relative to the outer tube 1 is achieved by moving the clamping end 71 in the notch 12 when subjected to force.

[0058] An embodiment of the present application also provides a seat, comprising the above-mentioned support legs. The technical effects of the seat and the above-mentioned support legs are roughly the same, and will not be repeated here.

[0059] In summary, the embodiment of the present application provides a support leg and a seat, wherein the body 31 of the adjustment plug 3 is fixedly connected to the inner tube 2 through the shift member 7, and a protective member 5 fixedly connected to the outer tube 1 and a second elastic member 52 connected between the protective member 5 and the body 31 are provided, so that the body 31 can move vertically relative to the outer tube 1; and a sliding block 41 provided with a first indicator mark and a second indicator mark is provided in the upper cover 4, and the upper cover 4 is provided on the top of the outer tube 1; when the support leg is in the supporting state, the inner tube 2 drives the body 31 and the push rod 32 to move upward, and the push rod 32 Move up and push the inclined surface 411 of the sliding block 41, so that the sliding block 41 moves to the first indicator mark exposed in the display window 42; and when the supporting leg is in a non-supporting state, the main body 31 drives the push rod 32 to move downward relative to the outer tube 1, and the push rod 32 gradually moves away from the inclined surface 411 of the sliding block 41. Under the action of the first elastic member 43, the sliding block 41 moves toward the push rod 32 until the second indicator mark is exposed in the display window 42. Since the first indicator mark or the second indicator mark is exposed through the display window 42 opened in the upper cover 4, it is convenient for the occupant to observe the status of the seat.

[0060] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
