Detailed implementation manners

[0035] The following is a specific introduction to the present invention in combination with the accompanying drawings and specific embodiments.

[0036] Embodiment 1: A foot-operated extensible sketch lighting lamp, as Figures 1-4 shown, includes a base 101. A cavity is formed inside the base 101. A piston frame 102 is slidably connected to the inner top of the base 101. A guide rod 103 is slidably connected to the rear side of the base 101. The top of the piston frame 102 is rotatably connected to a support rod 1021. A lighting body 1022 is fixedly installed on the front side of the support rod 1021. The lower front side of the base 101 is rotatably connected to a pedal 104. The lower front side of the base 101 is rotatably connected to an airbag 105. The top front side 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 communicated with the airbag 105. The first one-way valve 106 only allows external gas to enter the airbag 105 unidirectionally. The bottom of the airbag 105 is fixedly communicated with a hose 107. The rear end of the hose 107 is communicated with the cavity of the base 101. A second one-way valve 108 is fixedly installed on the hose 107.

[0037] As Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, it further includes a rotating rod 201. The rotating rod 201 is rotatably connected to the lower front side of the base 101. The pedal 104 swings downward to contact the rotating rod 201. A guide frame 203 is slidably connected to the lower front side of the base 101 in the front-rear 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 to the lower part of the base 101. The lifting frame 204 is fixedly connected between the elastic telescopic rods 205. The guide frame 203 is slidably connected to the lifting frame 204 through an inclined groove. An air release rod 206 is slidably connected to the front side of the base 101 in the up-down direction. An air release port is opened at the lower part of the air release rod 206. The bottom end of the air release rod 206 is in contact and cooperation with the top of the lifting frame 204. An air release hole 207 is opened at the lower front side of the base 101. The position height of the air release hole 207 is lower than the bottom of the piston frame 102. When the air release port of the air release rod 206 moves downward to align with the air release hole 207, the gas in the cavity of the base 101 is discharged. A resistance strip 208 is fixedly connected to the lower front side of the base 101. The resistance strip 208 contacts the air release rod 206, and the two are in frictional cooperation.

[0038] During the sketching process, when it is necessary to raise the lighting body 1022, step on the pedal 104 downward. The pedal 104 squeezes the airbag 105, and the gas in the airbag 105 is pressed into the hose 107, and then unidirectionally pressed into the cavity inside the base 101 through the second one-way valve 108. Under the action of the air pressure, the piston frame 102 rises by a fixed height. The guide rod 103 plays a guiding role. The piston frame 102 drives the lighting body 1022 to rise by 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, causing the airbag 105 to gradually reset, thereby pushing the pedal 104 to reset upward. Repeat this process. By intermittently stepping on the pedal 104 multiple times, the lighting body 1022 is raised section by section to the required height, so that there is no need to put down tools such as pens and papers in the hand to raise the height of the lighting body 1022 during sketching, and thus there is no need to pause the sketching work when adjusting the height of the lighting body 1022.

[0039] During the above process of repeatedly and intermittently stepping on the pedal 104, each time the pedal 104 is stepped on and rotated downward, the rotating rod 201 will be pushed to swing downward. The rotating rod 201 pushes the guide frame 203 to move backward through the first connecting rod 202. The guide frame 203 pulls the lifting frame 204 to move downward through the inclined slot, and the elastic telescopic rod 205 is compressed, so that the lifting frame 204 no longer presses against the air release rod 206. Under the action of its own gravity, the air release rod 206 slowly descends under the influence of the resistance strip 208. Since the pedal 104 is stepped on repeatedly and intermittently, 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 its initial position, resulting in that the air release port of the air release rod 206 can never be aligned with the air release hole 207, ensuring that during the process of raising the lighting body 1022, the gas will not leak, so that the lighting body 1022 can rise stably.

[0040] When it is necessary to lower the height of the lighting body 1022, just step on the pedal 104 downward without releasing it and step on it all the way down. The lifting frame 204 descends and no longer presses against the air release rod 206, so that the air release port of the air release rod 206 slowly descends to be aligned with the air release hole 207, so that an appropriate amount of gas in the cavity of the base 101 is discharged, making the piston frame 102 gradually descend, and then driving the lighting body 1022 to gradually descend through the support rod 1021. When the lighting body 1022 descends to the required height, then release the pedal 104, so that the air release rod 206 rises to be misaligned with the air release hole 207.

[0041] In this way, the present invention can not only repeatedly step on the pedal 104 intermittently in a short and fast manner to adaptively raise the lighting body 1022, but also step on the same pedal 104 all the way down at one time to adaptively lower the lighting body 1022. The operation is simple and practical.

[0042] Embodiment 2: On the basis of Embodiment 1, as Figure 2 and Figure 8 shown, it further includes a toothed wheel 301. The toothed wheel 301 is rotatably connected to the upper part of the front side of the base 101. The toothed wheel 301 is movably connected to the air release rod 206. The upper part of the front side of the piston frame 102 is fixedly connected with a limiting toothed wheel 302. The limiting toothed wheel 302 cooperates with the toothed wheel 301 to share the weight of the piston frame 102.

[0043] In order to share the weight of the lighting lamp body 1022 and reduce the wear on the piston frame 102, the specific operation is as follows: When the lighting lamp body 1022 is in the locked state, the limiting tooth 302 is engaged into the engaging tooth 301, thereby sharing the weight of the lighting lamp body 1022. When the lifting frame 204 rises to no longer abut against the air release rod 206, as the piston frame 102 rises, the limiting tooth 302 is driven to rise. The engaging tooth 301 is pushed by the limiting tooth 302 and rotates counterclockwise to make way. When the lighting lamp body 1022 descends, the lifting frame 204 no longer abuts against the air release rod 206, and the air release rod 206 descends, thereby pulling the engaging tooth 301 to rotate counterclockwise to make way. In summary, when the lighting lamp body 1022 is in the locked state, through the cooperation of the limiting tooth 302 and the engaging tooth 301, the weight of the lighting lamp is shared by the engaging tooth 301, the load on the piston at the bottom of the piston frame 102 is reduced, and the service life is extended. When the height of the lighting lamp needs to be adjusted, the engaging tooth 301 automatically makes way to avoid affecting the lifting of the lighting lamp body 1022.

[0044] Embodiment 3: On the basis of Embodiment 2, as Figure 2 , Figure 9 , Figure 10 and Figure 11 shown, it further includes a rotating frame 401. The rotating frame 401 is fixedly and symmetrically arranged on the left and right sides of the front part of the pedal 104. The base 101 is fixedly connected with fixing rings 402 symmetrically arranged along the left and right sides of the base 101. A suction cup 404 is slidably connected in the fixing ring 402 in the up and down direction. A through hole is formed in the middle of the suction cup 404. An activity cap 405 is slidably connected to the upper part of the suction cup 404. A spring 406 is sleeved between the activity cap 405 and the suction cup 404. A second connecting rod 403 is rotatably connected between the activity cap 405 and the rotating frame 401.

[0045] To prevent the base 101 from slipping on the ground when stepping on the pedal 104, the specific operation is as follows: When stepping 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. During the downward pressing process of the movable cap 405, it contacts the top of the suction cup 404 to complete the closing of the suction cup 404. As the movable cap 405 continues to descend, it pushes the suction cup 404 downward and expels the air inside the suction cup 404 to cause adsorption with the ground. The spring 406 deforms under force, thereby preventing the base 101 from slipping on the ground. When the pedal 104 is released, the pedal 104 drives the second connecting rod 403 to start resetting through the rotating frame 401, and the second connecting rod 403 thus pulls the movable cap 405 upward. The spring 406 resets, thereby releasing the closing of the suction cup 404, and the air pressure inside and outside the suction cup 404 returns to balance, losing the adsorption effect. In summary, through the cooperation of the movable cap 405 and the suction cup 404, when stepping on the pedal 104, the suction cup 404 is automatically pushed to adsorb to the ground to prevent the base 101 from slipping.

[0046] Embodiment 4: On the basis of Embodiment 3, as Figure 1 , Figure 2 and Figure 12 shown, it further includes a placement plate 501, and the placement plate 501 is fixedly connected to the front side of the lower part of the base 101. Anti-slip grooves are equally spaced at the bottom of the placement plate 501.

[0047] To be more comfortable when stepping on the pedal 104, by placing the foot on the placement plate 501, the angle of the ankle part when stepping on the pedal 104 is reduced, increasing the comfort. When the foot is placed on the placement plate 501, the increased weight of the foot is transmitted to the ground through the pedal 104, further increasing the friction between the base 101 and the ground to prevent slipping.

[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
