[0043] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] Reference Figures 1 to 5 As shown, this utility model provides a climbing device, including a base 10, a first support 20, a second support 30, and a third support 40, wherein:

[0045] The first support 20 is disposed on the base 10. The first support 20 can move along the first direction D1, which is the length direction of the base 10.

[0046] The second support 30 can move along the first preset path, and one end of the second support 30 is connected to the first support 20. The third support 40 can move along the second preset path, and one end of the third support 40 is connected to the base 10.

[0047] In the embodiments provided in this application, when the first support 20 moves along the first direction D1, it can drive the second support 30 to move along the first preset path. The first preset path is the connection point between the second support 30 and the first support 20, which moves synchronously along the first direction D1 as the first support 20 moves. When the second support 30 moves along the first preset path, the third support 40 moves along the second preset path. The second preset path is the trajectory of the third support 40 rotating around the connection point between the third support 40 and the base 10. Thus, through the linkage of the first support 20, the second support 30, and the third support 40, the height can be adjusted.

[0048] Reference Figure 3 As shown, when the first support 20 moves along the first direction D1 (left side in the figure), it drives the second support 30 to rotate clockwise, and the third support 40 rotates clockwise simultaneously, thereby achieving a decrease in height.

[0049] Similarly, when the first support 20 moves along the first direction D1 (right side in the figure), it drives the second support 30 to move counterclockwise, and the third support 40 rotates counterclockwise in sync, thereby achieving an increase in height.

[0050] Compared to existing technologies that require manual height adjustment, the climbing device of this application only needs to control the position of the first support 20 to achieve height adjustment without the need for tools. The adjustment method is simple and the adjustment time is short, making it suitable for scenarios that require frequent and rapid height adjustments, and thus has better applicability.

[0051] In one feasible implementation, refer to Figure 1 As shown, the base 10 is provided with a drive unit 11, and the first bracket 20 is provided with a drive engagement part 21. The drive unit 11 and the drive engagement part 21 can form a drive engagement to drive the first bracket 20 to move along the first direction D1. When the drive unit 11 generates power, it transmits the power to the first bracket 20 through interaction with the drive engagement part 21 to drive the first bracket 20 to move along the first direction D1, thereby precisely controlling the movement trajectory of the first bracket 20, so that the second bracket 30 and the third bracket 40 can move along the first preset path and the second preset path respectively, thereby stably controlling the height of the support platform 50.

[0052] Preferably, refer to Figure 6 As shown, the drive unit 11 includes a connecting rod 111 and a transmission screw 112. Both the connecting rod 111 and the transmission screw 112 extend along the first direction D1. The connecting rod 111 can rotate around its axis as the center line. One end of the connecting rod 111 is connected to the base 10, and the other end of the connecting rod 111 is connected to the transmission screw 112. Thus, the whole formed by the connection of the connecting rod 111 and the transmission screw 112 extends along the first direction D1.

[0053] Reference Figure 7 As shown, the drive engagement part 21 includes a lead screw nut 211, which is sleeved on the transmission lead screw 112. When the connecting rod 111 rotates along its axis, the transmission lead screw 112 rotates synchronously with the rotation of the connecting rod 111. With the cooperation of the lead screw nut 211 and the transmission lead screw 112, the lead screw nut 211 moves on the transmission lead screw 112, and then the first bracket 20 moves synchronously along the first direction D1 with the lead screw nut 211.

[0054] To facilitate the rotation of the connecting rod 111, a rotating handle 113 is provided on the base 10. The rotating handle 113 is connected to the end of the connecting rod 111 away from the transmission screw 112. When it is necessary to rotate the connecting rod 111, simply rotate the rotating handle 113 to drive the connecting rod 111 to rotate, which is convenient to operate.

[0055] In other embodiments, the driving part 11 and the driving engagement part 21 may adopt other structures or components that can drive the first bracket 20 to move along the first direction D1, which are not limited here.

[0056] When the first support 20 moves along the first direction D1, in order to ensure the stability of the first support 20 in moving along the first direction D1, in the embodiments provided in this application, referring to... Figure 6 as well as Figure 7 As shown, a first sliding part 12 is provided on the base 10, and a first sliding engagement part 22 is provided on the first bracket 20. The first sliding part 12 and the first sliding engagement part 22 can form a sliding engagement so that the first bracket 20 can move along the first direction D1.

[0057] In one feasible implementation, in the second direction D2, the first sliding part 12 is a sliding track 121 provided on opposite sides of the base 10, and the first sliding engagement part 22 is a roller bearing 221 provided at opposite ends of the first bracket 20 in the second direction D2. The second direction D2 is perpendicular to the first direction D1 and is the width direction of the base 10. When the first bracket 20 moves along the first direction D1, the roller bearings 221 at both ends of the first bracket 20 can roll in the corresponding sliding track 121, thereby enabling the first bracket 20 to move stably along the first direction D1.

[0058] In other embodiments, the first sliding part 12 and the first sliding engagement part 22 may adopt other structures or components that can form a sliding engagement, which are not limited here.

[0059] Reference Figures 1 to 3As shown in the embodiments provided in this application, the climbing device further includes a support platform 50, the other end of the second bracket 30 is connected to the support platform 50, and the other end of the third bracket 40 is connected to the support platform 50. Thus, when the first bracket 20 moves along the first direction D1, the height of the support platform 50 can be adjusted.

[0060] Reference Figure 3 As shown in the embodiment provided in this application, both the first support 20 and the support platform 50 are provided with a first pivot seat 61. The two opposite ends of the second support 30 are pivotally connected to the first support 20 and the support platform 50, respectively. The first preset path is the rotational movement path of the second support 30 centered on the pivot axis of the first pivot seat 61 provided on the first support 20. Since the two opposite ends of the second support 30 are connected to the first support 20 and the support platform 50 respectively through the first pivot seat 61, when the first support 20 moves along the first direction D1, the end of the second support 30 connected to the first support 20 rotates first, so that the second support 30 rotates along the first preset path. Under the action of the first pivot seat 61, the support platform 50 moves synchronously with the movement of the second support 30.

[0061] Reference Figure 7 , Figure 8 as well as Figure 11 As shown, in order to ensure the stability of the movement of the second support 30, two first pivot seats 61 are provided on both the first support 20 and the support platform 50. The two first pivot seats 61 on the first support 20 and the two first pivot seats 61 on the support platform 50 are both arranged along the second direction D2. Two first lugs 31 are provided at each of the opposite ends of the second support 30. The opposite ends of the second support 30 are connected to the two first pivot seats 61 through the two first lugs 31, respectively, to achieve pivot connection with the first support 20 and the support platform 50. Thus, each of the opposite ends of the second support 30 has two pivot points to support the stable movement of the second support 30 along the first preset path, thereby enabling the support platform 50 to move more smoothly.

[0062] Reference Figure 3 As shown, the base 10 and the support platform 50 are both provided with a second pivot seat 62. The two ends of the third bracket 40 are pivotally connected to the base 10 and the support platform 50 respectively. The second preset path is the rotational movement path of the third bracket 40 centered on the pivot axis of the second pivot seat 62 provided on the base 10.

[0063] Since the support platform 50 moves synchronously with the second bracket 30, in order for the support platform 50 to move smoothly, the third bracket 40 needs to move synchronously with the support platform 50 to provide support. Therefore, when the support platform 50 moves, the third bracket 40 is driven by the support platform 50 and moves along the second preset path. The pivot point between the third bracket 40 and the support platform 50 moves with the movement of the support platform. Therefore, the pivot seat of the second pivot seat 62 provided on the base 10 needs to be used as the center of rotation of the third bracket 40 to maintain the balance of the movement of the support platform 50.

[0064] Similarly, refer to Figure 6 as well as Figure 11 As shown, two second pivot seats 62 are provided on both the base 10 and the support platform 50. The two second pivot seats 62 on the base 10 and the support platform 50 are arranged along the second direction D2. The base 10 and the support platform 50 are connected by two third brackets 40. The two third brackets 40 are arranged parallel to each other along the second direction D2. The opposite ends of each third bracket 40 are pivotally connected to the base 10 and the support platform 50 respectively through the second pivot seats 62, so that the third bracket 40 can rotate more stably along the second preset path.

[0065] Specifically, refer to Figure 3 as well as Figure 11 As shown, the second pivot 62 includes two supports 621, as referenced. Figure 3 as well as Figure 9 As shown, the third support 40 includes two parallel support beams 41. Each support beam 41 has a second lug 411 at both ends. Each support beam 41 is connected to the support 621 through the second lug 411, thereby realizing the pivotal connection between the third support 40, the base 10, and the support platform 50.

[0066] When the support platform 50 is at a low height, the operator will be in a cantilever position on the support platform 50, thus posing a risk of tipping over. To avoid this situation, in the embodiments provided in this application, reference is made to... Figure 1 , Figure 2 , Figure 6 as well as Figure 10 As shown, the climbing device also includes a fourth support 70. The base 10 is provided with a second sliding part 13, and the fourth support 70 is provided with a second sliding engagement part 71. The second sliding part 13 and the second sliding engagement part 71 can form a sliding engagement so that the fourth support 70 can move along the first direction D1.

[0067] Reference Figure 3As shown, when the first support 20 moves along the first direction D1 (left side in the figure), the support platform 50 can be lowered, thereby reducing the height of the support platform 50. When the height of the support platform 50 poses a risk of tipping over, the fourth support 70 can be moved along the first direction D1 (right side in the figure, the opposite direction of the movement of the first support 20), so that the base 10, the second support 30, the third support 40 and the fourth support 70 form a triangular structure, so that the support platform 50 can remain stable when it is in a lower position, thereby ensuring the safety of the operator on the support platform 50.

[0068] The distance that the fourth support 70 moves along the first direction D1 can be adjusted according to the height of the support platform 50 so that the support platform 50 can remain stable.

[0069] During movement, the fourth support 70 can move stably along the first direction D1 through the sliding engagement of the second sliding part 13 and the second sliding engagement part 71. Preferably, the second sliding part 13 is a guide rail 131 located at the bottom of the base 10, and there are two guide rails 131 extending along the first direction D1 and located on both sides of the base 10; the second sliding engagement part 71 is a slider 711 located on the fourth support 70, and there are four sliders 711, with two sliders 711 corresponding to each guide rail 131. Each slider 711 can move on the corresponding guide rail 131, thereby realizing the stable movement of the fourth support 70 along the first direction D1.

[0070] In other embodiments, the second sliding part 13 and the second sliding engagement part 71 may adopt other structures or components that can form a sliding engagement, which are not limited here.

[0071] After the fourth support 70 is moved to the appropriate position, its position needs to be fixed so that the support platform 50 can be stably maintained at the corresponding height. To fix the position of the fourth support 70, in the embodiments provided in this application, reference is made to... Figure 6 as well as Figure 10 As shown, the base 10 is provided with a positioning part 14, and the fourth bracket 70 is provided with a positioning engagement part 72. The positioning part 14 and the positioning engagement part 72 can form a positioning engagement. When the fourth bracket 70 moves to a suitable position, the position of the fourth bracket 70 is fixed by the engagement of the positioning part 14 and the positioning engagement part 72.

[0072] In one feasible embodiment, the positioning part 14 is a spring pin 141 provided on the base 10, and the positioning mating part 72 is a pin limiting hole 721 provided on the fourth bracket 70. Multiple pin limiting holes 721 are provided along the first direction D1. When the fourth bracket 70 moves to a suitable position, the spring pin 141 is inserted into the corresponding pin limiting hole 721, thereby fixing the position of the fourth bracket 70. Providing multiple pin limiting holes 721 allows the fourth bracket 70 to have multiple fixable positions to adapt to the height of the support platform 50.

[0073] Even better, the base 10 is provided with two spring pins 141, which are arranged on the base 10 along the second direction. In the second direction, the fourth bracket 70 is provided with two rows of pin limiting holes 721, with each spring pin 141 corresponding to one row of pin limiting holes 721, which helps to improve the stability of the connection between the fourth bracket 70 and the base 10.

[0074] The positioning engagement of the spring pin 141 with the pin limiting hole 721 facilitates the adjustment of the position of the fourth bracket 70. When it is necessary to push the fourth bracket 70, press the button of the spring pin 141 to release the connection between the fourth bracket 70 and the base 10, so that the fourth bracket 70 can move. After the fourth bracket 70 moves to the appropriate position, release the button of the spring pin 141 so that the spring pin 141 is inserted into the corresponding pin limiting hole 721, thereby fixing the position of the fourth bracket 70.

[0075] In other embodiments, the positioning part 14 and the positioning mating part 72 may adopt other structures or components that can form a positioning mating, and there is no limitation here.

[0076] Reference Figure 1 , Figure 2 as well as Figure 12 As shown, the third support 40 is provided with multiple pedals 42, which are arranged sequentially and at intervals on the third support 40. Operators can reach the support platform 50 through the pedals 42. The pedals 42 are also provided with anti-slip parts 421 to prevent operators from slipping while climbing the support platform 50, thereby ensuring the safety of operators.

[0077] The anti-slip part 421 is preferably a patterned aluminum plate provided on the pedal 42, which increases the friction between the sole of the shoe and the pedal 42 when the operator steps on the pedal 42, thereby improving the safety of climbing onto the support platform 50.

[0078] To further improve the safety of the climbing device, handrails 43 are provided on both sides of the third support 40 to provide safety for operators to climb onto the support platform 50. The support platform 50 is also equipped with a platform guardrail 51 to prevent operators from falling while working on the support platform 50, thereby ensuring the safety of the operators.

[0079] Reference Figure 1 as well as Figure 2 As shown, the base 10 and the bottom of the fourth support 70 are equipped with multiple casters 80 to facilitate moving the climbing device to the required position.

[0080] Based on the above embodiments, the process of the climbing device of this application lowering the height of the support platform 50 is as follows: rotating the rotating handle 113, so that the first support 20 moves along the first direction D1 ( Figure 3 Move the second support 30 clockwise as it moves to the left, causing the support platform 50 to descend as the second support 30 rotates. The third support 40 also rotates clockwise as the support platform 50 descends. When the support platform 50 descends to a suitable height, stop rotating the handle 113.

[0081] If the height of the support platform 50 is low, push the fourth bracket 70 to move along the first direction D1 (the side opposite to the direction of movement of the first bracket 20). When the fourth bracket 70 moves to a position where the support platform 50 can maintain stability, use the spring pin 141 to insert into the pin limiting hole 721 to fix the position of the fourth bracket 70.

[0082] The process of raising the support platform 50 is as follows: rotate the rotating handle 113 so that the first support 20 moves along the first direction D1 ( Figure 3 The third support 40 moves counterclockwise under the drive of the support platform 50, causing the support platform 50 to rise. The third support 40 moves counterclockwise under the drive of the support platform 50, so that the support platform 50 rises smoothly. When the support platform 50 reaches a stable height, the fourth support 70 can be retracted.

[0083] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
