DETAILED DESCRIPTION

[0034] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Embodiment 1: A foot-operated stretchable sketch lighting lamp, such as Figure 1-Figure 4 As shown, it includes a base 101, a cavity is opened inside the base 101, a piston frame 102 is slidably connected to the top of the base 101, a guide rod 103 is slidably connected to the rear side of the base 101, a support rod 1021 is rotatably connected to the top of the piston frame 102, a lighting lamp body 1022 is fixedly installed on the front side of the support rod 1021, a pedal 104 is rotatably connected to the front side of the lower part of the base 101, an airbag 105 is rotatably connected to the front side of the lower part of the base 101, the front side of the top of the airbag 105 is movably connected to the pedal 104, a first one-way valve 106 is fixedly installed on the airbag 105, the first one-way valve 106 is connected to the airbag 105, the first one-way valve 106 only allows external gas to enter the airbag 105 in one direction, a hose 107 is fixedly connected to the bottom of the airbag 105, the rear end of the hose 107 is connected to the cavity of the base 101, and a second one-way valve 108 is fixedly installed on the hose 107.

[0036] like Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, it also includes a rotating rod 201, which is rotatably connected to the lower front side of the base 101, the pedal 104 swings downward and contacts the rotating rod 201, the lower front side of the base 101 is slidably connected to a guide frame 203 along the front-to-back direction, a first connecting rod 202 is rotatably connected between the guide frame 203 and the rotating rod 201, a lifting frame 204 is slidably connected to the lower front side of the base 101, two elastic telescopic rods 205 are fixed at the lower part of the base 101, the lifting frame 204 is fixedly connected between the elastic telescopic rods 205, and the guide frame 203 slides with the lifting frame 204 through an inclined slot. The base 101 is dynamically connected, and the front side of the base 101 is slidably connected to the air-deflating rod 206 in the up-and-down direction. The air-deflating port is opened at the lower part of the air-deflating rod 206, and the bottom end of the air-deflating rod 206 contacts and cooperates with the top of the lifting frame 204. A air-deflating hole 207 is opened on the front side of the lower part of the base 101. The position height of the air-deflating hole 207 is lower than the bottom of the piston frame 102. When the air-deflating port of the air-deflating rod 206 moves downward to align with the air-deflating hole 207, the gas in the cavity of the base 101 is discharged, and a resistance bar 208 is fixedly connected to the lower front side of the base 101. The resistance bar 208 contacts the air-deflating rod 206, and the two are matched by friction.

[0037] During the sketching process, when it is necessary to raise the lighting lamp body 1022, the pedal 104 is stepped down, and the pedal 104 squeezes the airbag 105, pressing the gas in the airbag 105 into the hose 107, and then into the cavity of the base 101 through the second one-way valve 108. Under the push of air pressure, the piston frame 102 rises to a fixed height, and the guide rod 103 plays a guiding role. The piston frame 102 drives the lighting lamp body 1022 to rise to a fixed height through the support rod 1021. When the pedal 104 is released, the external gas enters the airbag 105 through the first one-way valve 106, so that the airbag 105 gradually resets, thereby pushing the pedal 104 to reset upward, and repeating this process. By stepping on the pedal 104 intermittently for multiple times, the lighting lamp body 1022 is raised section by section to the required height, so that there is no need to put down the paper, pen and other tools in the hand and adjust the height of the lighting lamp body 1022 by hand when sketching, and there is no need to pause the sketching work when adjusting the height of the lighting lamp body 1022.

[0038] During the above-mentioned multi-frequency intermittent stepping on the pedal 104, each time the pedal 104 is turned downward, the rotating rod 201 will be pushed to swing downward, and the rotating rod 201 will push the guide frame 203 to move backward through the first connecting rod 202, and the guide frame 203 will pull the lifting frame 204 downward through the inclined groove, and the elastic telescopic rod 205 will be compressed, so that the lifting frame 204 no longer supports the air release rod 206. Under the action of its own gravity, the air release rod 206 is affected by the resistance bar 208 and slowly descends. Since the pedal 104 is stepped on intermittently for multiple frequencies, each time the pedal 104 is released, the elastic telescopic rod 205 will push the lifting frame 204 to rise, thereby pushing the air release rod 206 back to the initial position, resulting in the air release port of the air release rod 206 being unable to align with the air release hole 207, ensuring that the gas will not leak during the process of lifting the lighting lamp body 1022, so that the lighting lamp body 1022 can be stably raised.

[0039] When the height of the lighting lamp body 1022 needs to be lowered, one only needs to step on the pedal 104 without releasing it, and step it to the bottom. The lifting frame 204 will descend and no longer press against the air release rod 206, so that the air release port of the air release rod 206 will slowly descend to be aligned with the air release hole 207, so that the gas in the cavity of the base 101 is discharged in an appropriate amount, so that the piston frame 102 gradually descends, thereby driving the lighting lamp body 1022 to gradually descend through the support rod 1021. When the lighting lamp body 1022 descends to the required height, release the pedal 104 again, so that the air release rod 206 rises to be misaligned with the air release hole 207.

[0040] In this way, the present invention can realize adaptive raising of the lighting body 1022 by stepping on the pedal 104 intermittently in short and fast steps at multiple frequencies, and can also realize adaptive lowering of the lighting body 1022 by stepping on the same pedal 104 to the bottom at one time. The operation is simple and practical.

[0041] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 8 As shown, it also includes a latch tooth 301, which is rotatably connected to the upper front part of the base 101, and the latch tooth 301 is movably connected to the deflation rod 206. The upper front part of the piston frame 102 is fixedly connected to the limiting tooth 302, and the limiting tooth 302 cooperates with the latch tooth 301 to share the weight of the piston frame 102.

[0042] In order to share the weight of the lighting lamp body 1022 and reduce the loss of the piston frame 102, the specific operation is as follows: when the lighting lamp body 1022 is in a locked state, the limit tooth 302 is engaged with the latch tooth 301, thereby sharing the weight of the lighting lamp body 1022. When the lifting frame 204 rises to the point where it no longer abuts against the deflation rod 206, as the piston frame 102 rises, the limit tooth 302 is driven to rise. The latch tooth 301 is pushed by the limit tooth 302 to rotate counterclockwise to avoid the deflation rod 206. When the lighting lamp body 1022 is lowered, the lifting frame 204 is lifted and the piston frame 102 is lifted. The lowering frame 204 no longer presses against the air release rod 206, and the air release rod 206 descends, thereby pulling the latch tooth 301 to rotate counterclockwise to avoid it. In summary, when the lighting lamp body 1022 is in a locked state, the limit tooth 302 cooperates with the latch tooth 301, so that the latch tooth 301 can share the weight of the lighting lamp, reduce the load on the piston at the bottom of the piston frame 102, and extend the service life. When the height of the lighting lamp needs to be adjusted, the latch tooth 301 automatically avoids it to avoid affecting the lifting and lowering of the lighting lamp body 1022.

[0043] Embodiment 3: Based on embodiment 2, Figure 2 , Fig. 9 , Fig.10 and Fig.11 As shown, it also includes a rotating frame 401, which is fixedly and symmetrically arranged on the left and right sides of the front part of the pedal 104, and the base 101 is fixedly connected to a fixing ring 402 which is symmetrically arranged along the left and right sides of the base 101, and a suction cup 404 is slidably connected inside the fixing ring 402 along the up and down directions, and a through-type through hole is opened in the middle of the suction cup 404, and a movable cap 405 is slidably connected to the upper part of the suction cup 404, a spring 406 is sleeved between the movable cap 405 and the suction cup 404, and a second connecting rod 403 is rotatably connected between the movable cap 405 and the rotating frame 401.

[0044] In order to prevent the base 101 from slipping on the ground when the foot steps on the pedal 104, the specific operation is as follows: when the foot steps on the pedal 104, the pedal 104 drives the rotating frame 401 to start rotating, thereby pushing the movable cap 405 downward through the second connecting rod 403, and the movable cap 405 contacts the top of the suction cup 404 during the pressing process, completing the closing of the suction cup 404, and as the movable cap 405 continues to descend, the suction cup 404 is pushed down, and the air inside the suction cup 404 is discharged to make it adsorbed to the ground, and the spring 405 is pressed against the suction cup 404. 6 is deformed by force, thereby preventing the base 101 from slipping with the ground. When the pedal 104 is released, the pedal 104 drives the second connecting rod 403 to start to reset through the rotating frame 401. The second connecting rod 403 thereby pulls the movable cap 405 to rise, and the spring 406 resets, thereby releasing the closure of the suction cup 404. The air pressure inside and outside the suction cup 404 is restored to balance and the adsorption effect is lost. In summary, through the cooperation between the movable cap 405 and the suction cup 404, when the pedal 104 is stepped on, the suction cup 404 is automatically pushed to be adsorbed with the ground to prevent the base 101 from slipping.

[0045] Embodiment 4: Based on embodiment 3, Figure 1 , Figure 2 and Fig.12 As shown, a placement plate 501 is also included. The placement plate 501 is fixedly connected to the front side of the lower part of the base 101, and anti-slip grooves are evenly spaced at the bottom of the placement plate 501.

[0046] In order to make the pedal 104 more comfortable, the foot is placed on the placement board 501, and the angle at which the ankle is lifted when the foot is on the pedal 104 is reduced to increase comfort. When the foot is placed on the placement board 501, the increased weight of the foot is transferred to the ground through the pedal 104, further increasing the friction between the base 101 and the ground to prevent slipping.

[0047] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
