Description

Technical Field

[0001] This utility model belongs to the field of stilt technology, and in particular relates to a stilt structure. Background Technology

[0002] Construction stilts (also known as adjustable height stilts or suspension brackets) are auxiliary tools used in interior decoration. They lift furniture, boards, and other items off the ground through a support structure, making it easier for construction workers to work below.

[0003] When using stilts, the height needs to be adjusted according to different decoration height requirements. However, when adjusting the height of the support rods of traditional fixed stilts, it is usually necessary to remove the long rod bolts, release the fixation of the inner and outer support rods, and remove the long rod bolts on the other side as well. Then, the height of the stilts is adjusted. After the adjustment is completed, the holes of the inner and outer support rods need to be aligned, and then the long rod bolts need to be inserted and locked. This method is relatively complicated and cumbersome, and the adjustment efficiency is low. Utility Model Content

[0004] The purpose of this utility model is to provide a stilt stand structure. By setting a fixed outer rod, specifically by pulling a pull plate to disengage the insert rod from the inner support rod, thus releasing the fixation of the inner support rod, and after the square limiting strip leaves the fixed outer rod, the insert rod is rotated to restrict it, allowing for height adjustment. After adjustment, the pull plate is rotated again to insert the square limiting strip into the fixed outer rod, causing the insert rod to return to its original position through elasticity. The outer support rod is then slightly adjusted up and down to allow the insert rod to smoothly insert into the insertion hole on the inner support rod, quickly fixing the outer and inner support rods. This method eliminates the need for frequent hole adjustments, enabling rapid adjustment and solving the problem of traditional fixed stilt stands, which typically require disassembling long bolts to release the fixation of the inner and outer support rods, adjusting the height of the stilt stand, aligning the holes of the inner and outer support rods, inserting and locking the long bolts, resulting in a complex, cumbersome, and inefficient operation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a stilt stand structure, comprising two symmetrical foot pedals, each foot pedal having a hinge block hinged to its closest side via a pin, and further comprising: A telescopic mechanism is disposed between two hinge blocks. The telescopic mechanism includes an outer support rod fixedly connected to the upper hinge block by screws, and an inner support rod fixedly connected to the top of the lower hinge block by screws. The inner support rod is slidably connected inside the outer support rod. The inner support rod has several insertion holes inside. A fixed outer rod is fixedly connected to the outer surface of the outer support rod. An insertion rod is slidably connected inside the fixed outer rod. A protruding ring is fixedly connected to the outer surface of the insertion rod. A spring is sleeved on the outer side of the insertion rod. A tension rod is fixedly connected to one end of the outer side of the insertion rod. The plate has a square limiting strip fixedly connected to the top of the insertion rod. Pulling the plate causes the insertion rod to detach from the inner support rod, releasing the inner support rod from its fixation. After the square limiting strip leaves the fixed outer rod, rotating the insertion rod restricts its height. Once the adjustment is complete, rotating the plate again causes the square limiting strip to insert into the fixed outer rod, allowing the insertion rod to return to its original position through elasticity. The outer support rod is then slightly adjusted up and down to allow the insertion rod to smoothly insert into the insertion hole on the inner support rod. This method quickly restricts and fixes the outer and inner support rods, eliminating the need for frequent hole adjustments and enabling rapid adjustment. The insertion rod passes through the outer support rod on the side facing the outer support rod and extends into the insertion hole on the inner support rod. The insertion rod is adapted to the insertion hole on the inner support rod. The pull plate is set on the outside of the fixed outer rod, and a groove is opened at the bottom of the pull plate.

[0006] Furthermore, the side of the convex ring facing the outer support rod is in contact with the surface of the outer support rod, one end of the spring is in contact with the surface of the convex ring, and the other end of the spring is in contact with the inner wall of the fixed outer rod. A threaded shaft is fixedly connected to the side of the fixed outer rod away from the outer support rod. The threaded shaft is set in the bottom groove of the pull plate, and a locking ring is threadedly connected to the outer surface of the threaded shaft.

[0007] Furthermore, a foot pedal is fixedly connected to the top of the pedal located above, and a heel restraining block is fixedly connected to the top right side of the foot pedal by screws. Two straps are fixedly connected to the top of the foot pedal by screws, and the straps are used to bind the user's feet. The heel restraining block has multiple holes, which can be fixed to different positions with screws to meet the needs of different users.

[0008] Furthermore, a leg-fixing mechanism is provided above the foot pedal. The leg-fixing mechanism includes a sleeve rod located behind the foot pedal. An arc-shaped adapter block is fixedly connected to the top of the sleeve rod by bolts. Two sponge pads are fixedly connected to the inner side of the arc-shaped adapter block, and a limiting sleeve is fixedly connected to the outer end of the arc-shaped adapter block. A strap is fitted on the outer side of the arc-shaped adapter block, and the strap is located inside the limiting sleeve. Two sponge pads are fixedly connected to the outer side of the strap, and the sponge pads correspond to the sponge pads. After the sleeve rod is installed and the height is adjusted, the user's leg is placed against the inner side of the arc-shaped adapter block, and then the strap is tied around the user's leg. The sponge pads will wrap around the leg. Finally, the strap is tightened and fixed with a buckle. The cooperation of the sponge pads improves the comfort of the user's leg, avoids direct contact between the strap and the arc-shaped adapter block and the leg, and reduces the risk of leg injury.

[0009] Furthermore, a connecting rod is sleeved inside the sleeve rod, and a fixing block is inserted into the bottom of the connecting rod. The fixing block is fixedly connected to the bottom of the outer support rod on the right side. A threaded knob is threadedly connected to the outside of the fixing block. The threaded knob is used to lock the bottom of the connecting rod. A locking block is fixedly connected to the top of the back of the outer support rod on the right side via a bracket. The sleeve rod is set inside the locking block. The locking block is used to lock the sleeve rod in place with bolts. The height of the arc-shaped adapter block on the connecting rod can be adjusted by telescopic adjustment. The arc-shaped adapter block is adjusted to a suitable leg position for the user, and then the locking block is locked in place with bolts to lock the sleeve rod in place.

[0010] Furthermore, a spring bracket 1 is fixedly connected to the outer support rod on the left side, and two spring brackets 2 are fixedly connected to the outer support rod on the right side. A slide rod is slidably connected inside the spring bracket 1, and a return spring 1 and a return spring 2 are respectively sleeved on the outer side of the slide rod. The return spring 1 is located at the top of the spring bracket 1, and the return spring 2 is located at the bottom of the spring bracket 1. The top and bottom of the slide rod pass through the two spring brackets 2, and nuts are threaded to both ends of the slide rod. The elastic force of the return spring 1 is greater than that of the return spring 2. The elastic forces of the return spring 1 and the return spring 2 are used to assist the foot pedal in resetting and keeping the foot pedal in a horizontal state.

[0011] This utility model has the following beneficial effects: This invention uses a fixed outer rod. Specifically, pulling the pull plate causes the insert rod to detach from the inner support rod, releasing the inner support rod from its fixation. After the square limiting strip leaves the fixed outer rod, rotating the insert rod restricts its height. Once adjusted, rotating the pull plate again inserts the square limiting strip into the fixed outer rod, causing the insert rod to return to its original position via elasticity. The outer support rod is then slightly adjusted up and down to allow the insert rod to smoothly insert into the hole on the inner support rod. This method quickly and securely fixes the outer and inner support rods, eliminating the need for frequent hole adjustments and enabling rapid adjustment.

[0012] This invention utilizes an arc-shaped adapter block. Specifically, after the sleeve rod is installed and its height adjusted, the user's leg is placed against the inner side of the arc-shaped adapter block. Then, the second strap is tied around the user's leg, and the second sponge pad wraps around the leg. Finally, the second strap is tightened and secured with a buckle. The combination of the first and second sponge pads improves the user's leg comfort, prevents the second strap and the arc-shaped adapter block from directly contacting the leg, and reduces the risk of leg injury from constriction.

The inner support rod 22 is slidably connected inside the outer support rod 21 and has several insertion holes. A fixed outer rod 23 is fixedly connected to the outer surface of the outer support rod 21, and an insertion rod 231 is slidably connected inside the fixed outer rod 23. A protruding ring 232 is fixedly connected to the outer surface of the insertion rod 231, and a spring 233 is sleeved on the outer side of the insertion rod 231. A pull plate 234 is fixedly connected to one end of the outer side of the insertion rod 231, and a square limiting strip 235 is fixedly connected to the top of the insertion rod 231. Pulling the pull plate 234 causes the insertion rod 231 to disengage from the inner support rod 22, thus releasing the fixation of the inner support rod 22. Furthermore, after the square limiting strip 235 leaves the fixed outer rod 23, the insertion rod 231 is rotated to restrict it, thus adjusting the height. After adjustment, the pull plate 234 is rotated to insert the square limiting strip 235 into the fixed outer rod 23, and the insertion rod 231 is reset by elastic force. The outer support rod 21 is then slightly adjusted up and down to allow the insertion rod 231 to be smoothly inserted into the insertion hole on the inner support rod 22. This quickly restricts and fixes the outer support rod 21 and the inner support rod 22. This method does not require frequent adjustment of the hole position and can quickly complete the adjustment work. The side of the insertion rod 231 facing the outer support rod 21 passes through the outer support rod 21 and extends into the insertion hole on the inner support rod 22. The insertion rod 231 is compatible with the insertion hole on the inner support rod 22. The pull plate 234 is set on the outside of the fixed outer rod 23, and a groove is opened at the bottom of the pull plate 234.

The top of the foot pedal 3 is fixedly connected to two straps 32 by screws. The straps 32 are used to bind the user's feet. The heel restraining block 31 has multiple holes, which can be fixed in different positions with screws to meet the needs of different users.

[0021] A leg-fixing mechanism 4 is provided above the foot pedal 3. The leg-fixing mechanism 4 includes a sleeve rod 41 located behind the foot pedal 3. An arc-shaped adapter block 42 is fixedly connected to the top of the sleeve rod 41 by bolts. Two sponge pads 421 are fixedly connected to the inner side of the arc-shaped adapter block 42. A limiting sleeve 422 is fixedly connected to the outer end of the arc-shaped adapter block 42. A second strap 423 is fitted on the outer side of the arc-shaped adapter block 42. The second strap 423 is located inside the limiting sleeve 422. Two sponge pads 424 are fixedly connected to the outer side of the second strap 423. The second pad 424 corresponds to the first sponge pad 421; after the sleeve rod 41 is installed and the height is adjusted, the user's leg is placed against the inside of the curved adapter block 42, and then the second strap 423 is tied around the user's leg, and the second sponge pad 424 will wrap around the leg. Finally, the second strap 423 is tightened and fixed with the strap buckle. The cooperation of the first sponge pad 421 and the second sponge pad 424 can improve the comfort of the user's leg, avoid the second strap 423 and the curved adapter block 42 from directly contacting the leg, and this method can reduce the user's leg from being strangled.

[0022] A connecting rod 43 is fitted inside the sleeve rod 41. A fixing block 44 is inserted into the bottom of the connecting rod 43. The fixing block 44 is fixedly connected to the bottom of the outer support rod 21 on the right side. A threaded knob 441 is threadedly connected to the outside of the fixing block 44. The threaded knob 441 is used to lock the bottom of the connecting rod 43. A locking block 45 is fixedly connected to the top of the back of the outer support rod 21 on the right side through a bracket. The sleeve rod 41 is set inside the locking block 45. The locking block 45 uses bolts to lock the sleeve rod 41. The height of the arc-shaped adapter block 42 can be adjusted on the connecting rod 43. The arc-shaped adapter block 42 is adjusted to a suitable leg position for the user. Then, the locking block 45 is locked with bolts to lock the sleeve rod 41.

[0023] A spring bracket 5 is fixedly connected to the outer support rod 21 on the left side, and two spring brackets 51 are fixedly connected to the outer support rod 21 on the right side. A slide rod 52 is slidably connected inside the spring bracket 51. A return spring 53 and a return spring 54 are respectively sleeved on the outside of the slide rod 52. The return spring 53 is located at the top of the spring bracket 51, and the return spring 54 is located at the bottom of the spring bracket 51. The top and bottom of the slide rod 52 pass through the two spring brackets 51 respectively, and nuts are threaded to both ends of the slide rod 52. The elastic force of the return spring 53 is greater than that of the return spring 54. The elastic force of the return spring 53 and the return spring 54 are used to assist the foot pedal 3 in resetting so that the foot pedal 3 is in a horizontal state.

[0024] One specific application of this embodiment is: In use, first adjust the height of the foot pedal 3 according to the required height. First, rotate the locking ring 237 counterclockwise to remove it and release the fixation of the pull plate 234. Then, pull the pull plate 234 to disengage the insert rod 231 from the inner support rod 22, releasing the fixation of the inner support rod 22. At this time, the convex ring 232 will compress the spring 233. After the square limit strip 235 leaves the fixed outer rod 23, rotate the insert rod 231. The square limit strip 235 will then restrict the insert rod 231 to prevent it from springing back. Then, pull out the insert rod 231 on the other side in the same way to adjust the height of the foot pedal 3. After adjustment, rotate the pull plate 234 to insert the square limiting strip 235 into the fixed outer rod 23. The spring 233 will then spring back the insertion rod 231 to its original position. Then, adjust the foot pedal 3 up and down slightly to allow the insertion rod 231 to be smoothly inserted into the insertion hole on the inner support rod 22. This will quickly restrict and fix the outer support rod 21 and the inner support rod 22. At the same time, the square limiting strip 235 will position the pull plate 234 so that after the insertion rod 231 is reset, the pull plate 234 can be smoothly inserted into the threaded shaft 236. Finally, install the locking ring 237 on the threaded shaft 236 to lock and fix the pull plate 234, thus completing the adjustment. After the height adjustment is completed, the user places his foot on the foot pedal 3. The heel restraint block 31 then positions the foot. The heel restraint block 31 has multiple holes, which can be fixed in different positions with screws to meet the needs of different users. After the foot is placed, the foot is tied tightly with the strap 32 and secured with the strap buckle. Next, insert the connecting rod 43 into the locking block 45, and connect the bottom of the connecting rod 43 to the fixed insert block 44. Then, put the sleeve rod 41 on the connecting rod 43 and insert it into the locking block 45. Then, lock the connecting rod 43 onto the fixed insert block 44 using the threaded knob 441. The sleeve rod 41 can then extend and retract on the connecting rod 43 to adjust the height of the arc-shaped adapter block 42. Adjust the arc-shaped adapter block 42 to a suitable leg position for the user. Finally, tighten the locking block 45 with bolts. Once fixed, the sleeve 41 is secured. Then, the user's leg is placed against the inside of the curved adapter block 42, and the second strap 423 is tied around the user's leg. The second sponge pad 424 will wrap around the leg. Finally, the second strap 423 is tightened and secured with a buckle. The combination of the first sponge pad 421 and the second sponge pad 424 can improve the comfort of the user's leg, prevent the second strap 423 and the curved adapter block 42 from directly contacting the leg, and this method can reduce the risk of the user's leg being strangled. Finally, when the user walks, they will first lift the foot pedal 1 off the ground. When the foot pedal 1 lands, the connection between the outer support rod 21 and the inner support rod 22 and the foot pedal 1 will rotate. At this time, the outer support rod 21 on the left and the outer support rod 21 on the right will be affected by pressure. Through the cooperation of the second spring bracket 51 and the first spring bracket 5, the return spring 53 will be squeezed and stretched respectively. The slide rod 52 will slide in the first spring bracket 5. At this time, the outer support rods 21 on the left and right sides will be in a parallelogram state. Finally, the elastic force of the first return spring 53 and the second return spring 54 will assist the foot pedal 3 to return to a horizontal state. The pressure of the first return spring 53 and the second return spring 54 is adjustable. By adjusting the nut at the end of the second return spring 54, the pressure of the first return spring 53 and the second return spring 54 can be adjusted according to the elastic fatigue of the first return spring 53 and the second return spring 54.
