Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of climbing aids, and particularly relates to a climbing aid with a larger ground supporting surface. The climbing ladder can be a herringbone ladder, a straight ladder, a climbing platform or a car washing platform. BACKGROUND

[0002] There are many types of climbing aids, such as climbing platforms, escalators, etc. Among them, the climbing platform is more common. As a common device in various industrial, commercial and home environments, its main function is to provide a stable and flat working surface for various operations. The foot plate, as an important part of the climbing platform, not only bears the weight of the entire climbing platform, but also determines the height and stability of the climbing platform. The traditional design of the foot plate of the climbing platform usually adopts a fixed type, i.e. the foot plate is directly welded or bolted to the support column of the climbing platform, and cannot be adjusted.

[0003] In order to maintain a small package size, many climbing platforms use smaller foot plates. However, this design often sacrifices the stability of the product, especially in cases where the load is large or the working environment is unstable, the climbing platform is prone to shaking or tilting.

[0004] Therefore, in order to improve stability, some climbing platforms have increased the distance between the foot plates, but this has led to an increase in package size, which is not conducive to transportation and storage.

[0005] In order to solve the contradiction between package size and stability, some climbing platforms use detachable foot plate assemblies. A representative is the prior art, such as Chinese patent document No. CN201720873388.5, which discloses a climbing platform with telescopic ladder columns and foot plates. It can adjust the ground clearance of the platform by telescopic ladder columns, has the advantages of smaller size after storage and wider application range; it can also adjust the support width from the ground by telescopic leg plates, has the advantages of high support stability and safety.

[0006] The technical solution disclosed in the above patent document adopts the method of increasing the distance between the foot plates, but this method has limitations in specific operation, as follows:

[0007] Firstly, although this design solves the problem of package size and transportation to some extent, it needs to be assembled in the user's home, which increases the user's operation difficulty and time cost.

[0008] Secondly, the telescopic function of the existing product is usually only one level, which means that the height adjustment range of the climbing platform is limited. For users who need different working heights, this design obviously cannot meet their needs. Especially in some special working environments, such as laboratories and workshops, there are strict requirements for the height of the climbing platform, and one-level telescopic function is obviously not enough.

[0009] Furthermore, some footrests are limited by the position of the supporting legs and the extension length of the footrests, resulting in a relatively close distance between the farthest end of the footrest and the supporting leg. This makes the climbing equipment prone to tipping over when subjected to lateral forces. (That is, when one side of the climbing equipment is subjected to lateral thrust, if the bottom of the supporting leg on the affected side has little contact with the ground, it is easy to deflect around the bottom of the supporting leg on the other side as the center of rotation, causing a tipping over. In other words, it is easy to lift the supporting leg on the affected side. Although some climbing equipment is equipped with footrests to enhance stability, the distance between the farthest end of the footrest and the supporting leg is still relatively close. Although this improves the stability of the user standing on the climbing equipment, it is still easy to tip over when subjected to lateral forces.)

[0010] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0011] This invention provides a climbing tool with a larger ground support surface, aiming to solve one of the technical problems mentioned in the background art.

[0012] To achieve the above objectives, the technical solution adopted by this utility model is: a climbing device with a larger ground support surface, the climbing device including a climbing ladder frame mounted on the main body of the climbing device, the climbing ladder frame including at least two support legs spaced apart.

[0013] With the climbing ladder as a reference, the side opposite to each other of all the supporting legs is the inner side, and the side opposite to each other of all the supporting legs is the outer side;

[0014] Each of the supporting legs has a connecting pillar positioned downwards at its bottom, the connecting pillar being located on the outer side, and a foot plate being provided at the bottom end of the connecting pillar.

[0015] The relevant content in the above plan is explained as follows:

[0016] In the above scheme, the connecting column can be fixedly installed on the three surfaces of the four circumferences of the support leg, excluding the inner surface, by means of screws or other components. Preferably, the connecting column can be positioned and connected to the outer side.

[0017] A further technical solution is that the bottom sidewall of the connecting support column has a limiting hole.

[0018] A foot piece is provided at the bottom end of the connecting support column. The foot piece has a rotating end and a movable end. A hinge hole is provided on the rotating end of the foot piece at a position corresponding to the limiting hole.

[0019] The hinge hole of the foot pan and the limiting hole of the connecting column pass through the connecting shaft, and the foot pan is hinged to the bottom end of the connecting column, so that the foot pan has a supporting state and a storage state.

[0020] With the above design, the foot pan can be freely rotated, and can be switched between the supporting state and the storage state according to the packaging size and transportation problems, so that the packaging and transportation are not affected.

[0021] Further, the climbing ladder frame further comprises an elastic member.

[0022] The limiting hole has an upper limiting point and a lower limiting point, and when the connecting shaft passes through the limiting hole, the elastic member acts on the connecting shaft to force the connecting shaft to have a tendency to slide from the lower limiting point to the upper limiting point.

[0023] The foot pan is further provided with an abutting groove, and when the foot pan is in the supporting state, the abutting groove is configured to abut against the bottom end of the connecting column.

[0024] In the supporting state, the bottom surface of the foot pan forms a set angle with the surface in the length direction of the connecting column, the movable end of the foot pan is located outside the supporting leg, the bottom end of the connecting column is inserted into the abutting groove for limiting, and the connecting shaft is at the upper limiting point.

[0025] In order to make the foot pan enter the storage state, the elastic force of the elastic member is overcome, the bottom end of the connecting column is separated from the abutting groove in the process that the connecting shaft slides from the upper limiting point to the lower limiting point, the foot pan is flipped with the movable end towards the inside of the supporting leg until it enters the storage state with the connecting shaft as the rotation center, and after the external force is removed, the connecting shaft is kept at the upper limiting point position by the elastic force of the elastic member.

[0026] Although the foot pan can be freely rotated, sometimes the stability after switching needs to be ensured, and in order to solve this problem, further, the limiting hole is a long strip-shaped hole along the length direction of the supporting leg, and the upper limiting point and the lower limiting point are respectively located at the upper end and the lower end of the hole, and with the above design, the foot pan and the bottom end of the connecting column can generate a rotation distance during the transformation by directly changing the position of the connecting shaft in the limiting hole.

[0027] Further, the connecting column has a cavity, and the bottom end of the connecting column has a lower end cover inserted into the cavity, and the lower end cover is closed at the bottom and open at the top, so that the cavity is blocked.

[0028] The side wall of the lower end cover is provided with a guide hole at a position corresponding to the limiting hole, and the guide hole has the same structure as the limiting hole.

[0029] When the foot pan is hinged with the connecting column, the end of the connecting shaft is located in the hinge hole of the foot pan, and the shaft body of the connecting shaft is located in the limiting hole and the guide hole;

[0030] When the elastic member acts on the connecting shaft, the lower end cover is configured to accommodate the elastic member.

[0031] With the above design, the cavity bottom of the connecting column is blocked, and the presence of the lower end cover can also serve as a position for limiting the elastic member, preventing the elastic member from shifting during stretching. Further, to solve this problem, a spring limiting sleeve can be provided at the bottom of the lower end cover to limit the spring, and the spring limiting sleeve is provided with an upper and lower sliding groove corresponding to the position of the connecting shaft.

[0032] That is, in order to prevent the elastic member from shifting when driving the connecting shaft to slide along the limiting hole, the end of the end cover body inserted into the cavity has a clearance slot corresponding to the elastic member for avoiding and limiting the elastic member.

[0033] Further, the foot pan has a limiting groove, and the abutting groove is arranged at the groove bottom of the limiting groove. When the foot pan is in the storage state, the groove width of the limiting groove is configured to be not less than the width of the connecting column.

[0034] With the above design, the inner side wall of the limiting groove and the connecting column are gap-fitted, and the gap is not large, which not only makes the foot pan in the storage state stable, but also prevents the foot pan from shaking.

[0035] Further, the limiting groove is arranged on the surface of the foot pan, and the opening one and the opening two are arranged at both ends of the limiting groove along the rotation direction of the foot pan. A plurality of abutting strips fixed to the groove bottom of the limiting groove are arranged in the opening one, and the abutting groove is formed between the end of the abutting strip close to the opening two and the opening two.

[0036] The end of the abutting strip close to the opening two is provided with a deflection surface.

[0037] With the above design, the foot pan in the storage state and the connecting column are arranged in parallel, and when the foot pan and the connecting column rotate relative to each other, the deflection surface can also be avoided to prevent the abutting strip from being blocked.

[0038] Further, the side surface of the abutting strip away from the groove bottom of the limiting groove is flush with the bottom of the opening two.

[0039] When the foot pan rotates around the connecting shaft as the rotation center to the surface in the length direction of the foot pan parallel to the connecting column, the bottom of the opening two abuts against the side surface of the connecting column.

[0040] If the height of the abutting strip is not flush with the bottom of the opening two, the foot pan will be inclined to rest on the connecting column, at this time, the foot pan is easy to deflect by a small amplitude through the connecting shaft, and the design further makes the stability between the foot pan and the connecting column better.

[0041] Further technical solutions, both ends of the elastic member have a hanging hook;

[0042] The inner side wall of the cavity is provided with a hanging hole, and an anti-skid point is arranged in the hanging hole;

[0043] One of the hanging hooks is connected with the anti-skid point, and the other hanging hook is connected with the connecting shaft.

[0044] Through the above design, the elastic member can quickly complete the fixing operation, that is, one hanging hook is connected with the connecting shaft, and the other hanging hook is connected with the anti-skid point through the auxiliary metal hook and other components.

[0045] Further technical solutions, the support leg side is provided with a connecting piece, and the connecting piece is provided with a mounting position;

[0046] The connecting column is arranged on the mounting position, and the connecting column is arranged to slide relative to the surface in the length direction of the support leg, and is locked after sliding for a distance.

[0047] Through the above design, the connecting column and the support leg can be freely telescopic, so as to solve the problem that the height adjustment range of the current climbing platform is limited.

[0048] Although the current climbing platform can complete height adjustment by setting telescopic support legs, the strength requirement of the support leg for this operation is a problem, that is, in order to meet the telescopic purpose, two square tubes or circular tubes are necessarily arranged in a sleeved manner, in which case, the two square tubes or circular tubes need to be designed to slide up and down, while also ensuring that they can be quickly fixed, and the volume is small. Under this condition, either the outer tube is thin, or the inner tube is thin, which is easy to bend during use.

[0049] Further technical solutions, the connecting column and the support leg are provided with a plurality of locking holes on the opposite side surfaces;

[0050] A plurality of locking holes are arranged from bottom to top along the length direction of the connecting column;

[0051] The climbing tool further comprises a locking member, and the locking member is provided with a penetrating end, when the connecting column is locked relative to the support leg, the penetrating end of the locking member is positioned and inserted into a group of locking holes.

[0052] With the above design, the connecting column and the supporting leg can be quickly fixed and detached.

[0053] Further, the locking member is arranged on the side surface of the supporting leg opposite to the connecting column, the supporting leg has a through hole, and the through end of the locking member passes through the through hole of the supporting leg and the locking hole of the connecting column to position and connect the connecting column and the supporting leg.

[0054] The through end of the locking member can be regarded as a screw, but when arranged on the connecting column, it shakes greatly; if arranged on the connecting member, the force applied to the connecting member is large, and the strength of the connecting member is low, and the above design can ensure the stability and strength during fixing.

[0055] Further, the supporting legs are arranged in pairs along the length direction of the climbing tool body; the connecting members are arranged on the side surfaces of the two supporting legs opposite to each other.

[0056] The mounting position is a hole arranged on the connecting member, and the hole is matched with the connecting column in shape.

[0057] With the above design, the connecting column is located on the outer side surface of the supporting leg, so that the contact area with the ground is larger when the foot plate is in the supporting state.

[0058] In the above scheme, the relevant contents are explained as follows:

[0059] In the above scheme, when the foot plate changes from the supporting state to the storage state, the foot plate will not exceed the outer side of the connecting column, so that when the climbing tool is packed, it only needs to be packed according to the length of the climbing tool itself, without considering the foot plate.

[0060] In the above scheme, when the foot plate is in the supporting state, most of the foot plate is located on the outer side of the connecting column, which can greatly expand the contact range of the climbing tool on the ground, so that the climbing tool has higher stability.

[0061] In the above scheme, the connecting column is arranged to slide relative to the surface in the length direction of the supporting leg, and is locked after sliding a certain distance, which means that the connecting column can slide up and down along the surface in the length direction of the supporting leg, and after sliding a certain distance, the connecting column can be locked by a screw. The screw can be arranged in the following positions: first, directly arranged on the side wall of the connecting column, locked by the connecting member; second, the screw passes through the connecting member to fix the connecting member and the connecting column; third, the screw passes through the supporting leg to lock the connecting column and the supporting leg.

[0062] In the above scheme, the elastic member can be selected from a spring, a tension spring and the like, the support leg is a prior art, and no further description is made herein, and the connecting shaft can be selected from a bolt, a pin, a rotating shaft or a rivet, and the specific use is selected according to the requirement.

[0063] In the utility model, the connecting support can be a rod-shaped structure with a longer size or a shorter size, an upper end cover can be installed on the upper end of the connecting support, and the specific structure is as follows Figure 1 Or Figure 2 .

[0064] In the above scheme, the connecting shaft can be rotated into a nut cap and abut against the foot plate to realize the limiting of the connecting shaft.

[0065] As for the "first", "second" and the like used in the present text, they do not mean to particularly indicate the order or the sequence, nor to limit the present case, but only to distinguish the components or operations described by the same technical terms.

[0066] As for the "connection" or "positioning" used in the present text, it can mean that two or more components or devices directly contact each other or indirectly contact each other, or it can mean that two or more components or devices operate or act on each other.

[0067] As for the "contains", "includes", "has" and the like used in the present text, they are all open terms, that is, they mean to contain but not limited to.

[0068] As for the words (terms) used in the present text, they generally have the usual meaning of each word used in this field, in the content of the present case and in the special content, unless otherwise specified. Some words used to describe the present case will be discussed below or elsewhere in the specification to provide additional guidance for those skilled in the art on the description of the present case.

[0069] As for the "front", "back", "up", "down", "left", "right" and the like used in the present text, they are all directional words, which are only used to illustrate the positional relationship between the structures in the present case, and are not used to limit the protection scheme and the specific direction in the actual implementation of the present case.

[0070] The working principle and advantages of the utility model are as follows:

[0071] 1、In the utility model, the foot plate and the connecting support are arranged on the outer side, so that the distance between the farthest end of the foot plate and the support leg is large, that is, the contact area with the ground is larger, and the overturning probability is smaller when subjected to a lateral force.

[0072] 2、In the utility model, the foot plate can be freely turned over for packaging and transportation, and in the turned-over folded state, it will not exceed the edge of the connecting support, thereby reducing the size and difficulty required for packaging.

[0073] 3. The connecting column and the support leg can slide relative to each other, allowing the height of the climbing equipment to be freely adjusted without affecting the strength of the connecting column or support leg during adjustment.

[0074] In summary, this utility model, through the cooperation of the connector, connecting column, foot plate, and connecting shaft, enables the height adjustment of the climbing equipment and the rapid switching between the foot plate's supported state (i.e., working state) and its stored state. Specifically, when the height of the climbing equipment's main body does not meet the requirements, the connecting column is directly guided to slide down relative to the surface of the supporting leg along its length, and then locked after sliding a set distance, thus completing the height adjustment operation of the climbing equipment. When the foot plate is in use, the bottom surface of the foot plate forms a set angle with the surface of the connecting column along its length, and the movable end of the foot plate is located outside the supporting leg, i.e., the contact area with the ground is larger. In order to put the foot plate into the stored state and overcome the elastic force of the elastic element, as the connecting shaft slides from the upper stop point to the lower stop point, the bottom end of the connecting column disengages from the abutment groove, and the foot plate rotates around the connecting shaft as the rotation center, with the movable end flipping towards the inside of the supporting leg until it enters the stored state. After the external force is removed, the elastic force of the elastic element pulls the connecting shaft to remain at the upper stop point, thereby enabling the foot plate to be stored and folded, facilitating subsequent packaging and transportation.

DETAILED DESCRIPTION

[0089] The present utility model will be further described below in combination with the drawings and embodiments:

[0090] Embodiment: the present case will be clearly explained by the drawings and detailed description, any person skilled in the art can change and modify the technology taught by the present case after understanding the embodiments of the present case, which does not deviate from the spirit and scope of the present case.

[0091] The terms in this paper are only for describing specific embodiments and are not intended to limit the present case. The singular form such as "a", "this", "this", "this" and "the" as used herein also includes the plural form.

[0092] Referring to the drawings Figures 1-13 ​​As shown, a climbing tool with a larger ground supporting surface, the climbing tool comprising a climbing ladder frame 28 arranged on a main body of the climbing tool, the climbing ladder frame 28 comprising at least two support legs 6 arranged at a distance, all of the support legs 6 being on one side relative to the climbing ladder frame 28 an inner side, and all of the support legs 6 being on the other side relative to the climbing ladder frame 28 an outer side;

[0093] A connecting strut 2 is connected to the bottom of each of the support legs 6, the connecting strut 2 being located on the outer side, and the connecting strut 2 being provided with a foot pad at the bottom end.

[0094] In the above scheme, the relevant content is explained as follows:

[0095] In the above scheme, the connecting strut 2 can be fixedly installed on three surfaces of the four peripheral surfaces of the support leg 6 except the surface on the inner side, and preferably, the connecting strut 2 can be connected to the outer side.

[0096] In some specific embodiments, the bottom end side wall of the connecting strut 2 has a limiting hole 8,

[0097] The foot pad 3 is arranged at the bottom end of the connecting strut 2, the foot pad 3 having a rotating end and a movable end, and the rotating end of the foot pad 3 having a hinge hole 11 at a position corresponding to the limiting hole 8;

[0098] The hinge hole 11 of the foot pad 3 and the limiting hole 8 of the connecting strut 2 pass through a connecting shaft 4, and the foot pad 3 is hinged to the bottom end of the connecting strut 2, so that the foot pad 3 has a supporting state and a storage state.

[0099] With the above design, the foot pad can be freely rotated, and can also be switched between the supporting state and the storage state according to the packaging size and transportation problems, so that the packaging and transportation are not affected.

[0100] In some specific embodiments, the climbing ladder frame 28 further comprises a resilient member 5;

[0101] The limiting hole 8 has an upper limiting point 9 and a lower limiting point 10; when the connecting shaft 4 passes through the limiting hole 8, the resilient member 5 acts on the connecting shaft 4, forcing the connecting shaft 4 to have a downward trend from the lower stop point to the upper stop point;

[0102] The foot pad 3 is further provided with an abutting groove 12, and when the foot pad 3 is in the supporting state, the abutting groove 12 is configured to abut against the bottom end of the connecting strut 2.

[0103] In the supporting state, the bottom surface of the foot pan 3 is at a set angle with the surface in the length direction of the connecting column 2, the movable end of the foot pan 3 is located outside the supporting leg 6, the bottom end of the connecting column 2 is inserted into the abutting groove 12 for limiting, and the connecting shaft 4 is at the upper stop point;

[0104] In order to make the foot pan 3 enter the storage state, the bottom end of the connecting column 2 is separated from the abutting groove 12 in the process that the connecting shaft 4 slides from the upper stop point to the lower stop point, the foot pan 3 is flipped with the movable end towards the inside of the supporting leg 6 with the connecting shaft 4 as the rotating center until it enters the storage state, and after the external force is removed, the connecting shaft 4 is kept at the position of the upper stop point by the elastic force of the elastic element 5.

[0105] Although the foot pan can rotate freely, sometimes the stability after switching needs to be ensured, and in order to solve this problem, the further technical scheme is that the limiting hole 8 is a long strip-shaped hole along the length direction of the supporting leg 6, the upper limiting point 9 and the lower limiting point 10 are respectively located at the upper end and the lower end of the hole, and by the above design, the foot pan 3 can directly change the position in the limiting hole 8 through the connecting shaft 4 in the process of transformation, so that the rotating distance between the foot pan 3 and the bottom end of the connecting column 2 can be generated.

[0106] In some specific embodiments, the connecting column 2 has a cavity 16, and the bottom end of the connecting column 2 has a lower end cover 17 inserted into the cavity 16, which is closed at the bottom and open at the top, so that the cavity 16 is blocked;

[0107] The sidewall of the lower end cover 17 is provided with a guide hole 18 at the corresponding position of the limiting hole 8, and the guide hole 18 has the same structure as the limiting hole 8;

[0108] When the foot pan 3 is hinged with the connecting column 2, the end of the connecting shaft 4 is located in the hinge hole 11 of the foot pan 3, and the shaft body of the connecting shaft 4 is located in the limiting hole 8 and the guide hole 18;

[0109] When the elastic element 5 acts on the connecting shaft 4, the lower end cover 17 is configured to accommodate the elastic element 5.

[0110] By the above design, the bottom of the cavity 16 of the connecting column 2 is blocked, and the presence of the lower end cover 17 can also limit the position of the elastic element 5, preventing the position deviation of the elastic element 5 during stretching. Further, in order to solve this problem, a spring limiting sleeve can be arranged at the bottom of the lower end cover 17 to limit the spring, and the spring limiting sleeve is provided with an upper and lower sliding groove at the corresponding position of the connecting shaft 4.

[0111] In order to prevent the elastic member 5 from being deviated when the connecting shaft 4 is driven to slide along the limiting hole 8, one end of the end cover body inserted into the cavity 16 is provided with a clearance groove 27 corresponding to the elastic member 5, so as to avoid the elastic member 5.

[0112] Meanwhile, the elastic member 5 is in an inclined state when it is hung. In order to prevent the elastic member 5 from generating large friction during stretching, the clearance groove 27 is used for avoiding.

[0113] In some embodiments, the foot plate 3 is provided with a limiting groove 19, and the abutting groove 12 is arranged at the groove bottom of the limiting groove 19. When the foot plate 3 is in the storage state, the groove width of the limiting groove 19 is configured to be not less than the width of the connecting column 2.

[0114] Through the above design, the inner side wall of the limiting groove 19 and the connecting column 2 are gap-fitted, and the gap is not large. This not only makes the foot plate 3 in the storage state stable, but also prevents the foot plate 3 from shaking.

[0115] In some embodiments, the limiting groove 19 is arranged on the surface of the foot plate 3, and opening one 20 and opening two 21 are arranged at both ends of the limiting groove 19 along the rotation direction of the foot plate 3. A plurality of abutting strips 22 fixedly connected with the groove bottom of the limiting groove 19 are arranged in the opening one 20, and the abutting groove 12 is formed between one end of the abutting strip 22 close to the opening two 21 and the opening two 21.

[0116] One end of the abutting strip 22 close to the opening two 21 is provided with a deflection surface 23.

[0117] Through the above design, the foot plate 3 in the storage state is parallel to the connecting column 2. When the foot plate 3 and the connecting column 2 are relatively rotated, the deflection surface 23 can also be avoided to prevent the abutting strip 22 from being blocked.

[0118] Specifically, when the foot plate 3 is in the use state, the bottom end of the connecting column 2 is abutted with the groove bottom of the abutting groove 12, so that the bottom of the supporting leg 6 has a larger stress area, and the abutting groove 12 has a certain depth. Therefore, the connecting shaft 4 is at the upper stop point at this time.

[0119] Once it needs to be stored, an external force is first used to guide the connecting shaft 4 to slide from the upper stop point to the lower stop point. When the lower stop point is reached, the bottom end of the supporting leg 6 is at least flush with the lowest end of the deflection surface 23. Then, the foot plate 3 is driven to rotate towards the side of the supporting leg 6 close to the climbing tool with the connecting shaft 4 as the rotation center. That is, through the arrangement of the deflection surface 23, when the connecting column 2 and the foot plate 3 move relatively, there is no obstacle in the movement track of the foot plate 3.

[0120] When the surface of the footbath member 3 in the length direction is parallel to the support leg 6, the bottom of the second opening 21 is in abutment with the surface of the support leg 6, and the side surface of the abutment strip 22 away from the bottom of the limiting groove 19 is in abutment with the surface of the support leg 6. During the process of sliding the connecting shaft 4 from the upper stop point to the lower stop point, the connecting shaft 4 drives the elastic member 5 to generate a restoring force to pull the connecting shaft 4 back to the original position. Then, the external force is removed, the elastic member 5 pulls the connecting shaft 4 back to the original position to form the storage state of the footbath member 3. During the process, the footbath member 3 rotates towards the side of the climbing tool, so that the footbath member 3 does not protrude from the side of the climbing tool. Moreover, the storage mode does not require disassembly of the footbath member 3, thereby reducing the installation cost of repeated disassembly and assembly.

[0121] In some embodiments, the side surface of the abutment strip 22 away from the bottom of the limiting groove 19 is flush with the bottom of the second opening 21.

[0122] When the footbath member 3 rotates around the connecting shaft 4 to be parallel to the connecting column 2 in the length direction, the bottom of the second opening 21 is in abutment with the side surface of the connecting column 2.

[0123] If the height of the abutment strip 22 is not flush with the bottom of the second opening 21, the footbath member 3 will be inclined and supported on the connecting column 2. At this time, the footbath member 3 is easy to be slightly deflected by the connecting shaft 4. By the above design, the stability between the footbath member 3 and the connecting column 2 is further improved.

[0124] The elastic member 5 is further limited so that it can be quickly replaced when the elasticity of the elastic member 5 fails. Therefore, in some embodiments, both ends of the elastic member 5 are provided with a hanging hook 24.

[0125] The inner side wall of the cavity 16 is provided with a hanging hole 25, and the hanging hole 25 is provided with an anti-skid point 26.

[0126] One of the hanging hooks 24 is connected with the anti-skid point 26, and the other hanging hook 24 is connected with the connecting shaft 4.

[0127] During installation of the elastic member 5:

[0128] One of the hanging hooks 24 is directly connected with the side wall of the connecting shaft 4, and the other hanging hook 24 is connected with the anti-skid point 26 by means of a metal hook or the like. In this way, the hanging hook 24 connected in the hanging point is limited, and the connection of the elastic member 5 is completed. The whole process is convenient, simple and fast, and the elastic member 5 can be quickly replaced when it fails.

[0129] In some embodiments, the side of the support leg 6 is provided with a connecting member 1, and the connecting member 1 is provided with a mounting position 7.

[0130] The connecting column 2 is arranged on the mounting position 7, and the connecting column 2 is arranged in sliding mode relative to the surface in the length direction of the supporting leg 6, and is locked after a sliding setting distance.

[0131] Through the above design, the connecting column 2 and the supporting leg 6 can be freely telescopic, so as to solve the problem of limited height adjustment range of the current climbing platform.

[0132] Although the current climbing platform can complete height adjustment by setting the telescopic supporting leg 6, the strength requirement of the supporting leg 6 for this operation is a problem, that is, in order to meet the telescopic purpose, two square tubes or circular tubes that are sleeved together must be set. In this case, the two square tubes or circular tubes need to be designed to slide up and down, and also need to be quickly fixed, and the volume also needs to be small. In this case, the outer tube is thin or the inner tube is thin, so that bending phenomenon is easy to occur during use.

[0133] In some embodiments, a plurality of locking holes 13 are arranged on the side surface opposite to the supporting leg 6 of the connecting column 2;

[0134] The plurality of locking holes 13 are arranged in sequence from bottom to top along the length direction of the connecting column 2;

[0135] The climbing tool further comprises a locking piece 14, the locking piece 14 has a penetrating end, when the connecting column 2 is locked relative to the supporting leg 6, the penetrating end of the locking piece 14 is positioned and inserted with a group of locking holes 13.

[0136] Through the above design, the connecting column 2 and the supporting leg 6 can be quickly fixed and disassembled.

[0137] In some embodiments, the locking piece 14 is arranged on the side surface opposite to the connecting column 2 of the supporting leg 6, the supporting leg 6 has a penetrating through hole 15, the penetrating end of the locking piece 14 penetrates through the penetrating through hole 15 on the supporting leg 6 and the locking hole 13 on the connecting column 2, and the connecting column 2 and the supporting leg 6 are positioned and connected.

[0138] The penetrating end of the locking piece 14 can be regarded as a screw, but when it is arranged on the connecting column 2, it shakes greatly; if it is arranged on the connecting piece 1, the force applied to the connecting piece 1 is large, and the strength of the connecting piece 1 is low, and through the above design, the stability and strength during fixing can be guaranteed.

[0139] That is, after the positioning of the connecting piece 1 is realized, the penetrating end of the locking piece 14 penetrates through the penetrating through hole 15 and is positioned and inserted with a group of locking holes 13 to realize fixing.

[0140] If disassembly is required, it can be directly pulled out.

[0141] Each set of locking holes 13 can be composed of one or more locking holes 13, and two are selected in the embodiment. The corresponding through holes 15 and the through holes on the locking member 14 (i.e. the support) are provided with two.

[0142] In some specific embodiments, the support legs 6 are arranged in pairs and along the length direction of the climbing tool body; the connecting member 1 is arranged on the surface of the two support legs 6 opposite to each other;

[0143] The mounting position 7 is a channel provided on the connecting member 1, and the channel is matched with the connecting support 2 in shape.

[0144] By the above design, the connecting support 2 is located on the outer surface of the support leg 6, so that the contact area with the ground is larger when the foot pad member 3 is in the supporting state.

[0145] In the embodiment, the relevant content is explained as follows:

[0146] In the embodiment, when the foot pad member 3 is transformed from the supporting state to the storage state, the foot pad member 3 will not exceed the outer side of the connecting support 2, so that the climbing tool can be packaged according to the length of the climbing tool itself without considering the foot pad member 3.

[0147] In the embodiment, when the foot pad member 3 is in the supporting state, most of the foot pad member 3 is located on the outer side of the connecting support 2, so that the contact range of the climbing tool on the ground can be expanded to a large extent, and the stability of the climbing tool is higher.

[0148] In the embodiment, the connecting support 2 is arranged to slide relative to the surface in the length direction of the support leg 6, and is locked after sliding for a set distance, which means that the connecting support 2 can slide up and down along the surface in the length direction of the support leg 6, and can be locked by a screw after sliding for a set distance. The screw is arranged at the following positions: first, the screw is directly arranged on the side wall of the connecting support 2, and the screw is locked by the connecting member 1; second, the screw passes through the connecting member 1 to fix the connecting member 1 and the connecting support 2; third, the screw passes through the support leg 6 to lock the connecting support 2 and the support leg 6.

[0149] In the embodiment, the elastic member 5 can be selected from a spring, a tension spring and the like, and the support leg 6 is a prior art which will not be described in detail here. The connecting shaft 4 can be selected from a bolt, a pin, a rotating shaft or a rivet, and the specific use can be selected according to the requirement.

[0150] In the embodiment, the connecting support 2 can be selected from a rod-shaped structure with a longer size or a shorter size, and an upper end cover can be arranged on the upper end of the connecting support 2.

[0151] In this embodiment, the connecting shaft 4 is rotatable into the nut and abuts against the foot pan 3 to limit the connecting shaft 4.

[0152] The working principle is that the elastic member 5 is first placed in the lower end cover 17 and is installed in the connecting column 2, then the foot pan 3 is sleeved, the connecting shaft 4 is penetrated, one of the hanging hooks 24 is connected with the sidewall of the connecting shaft 4, and the other hanging hook 24 is connected with the anti-skid point 26 by means of the metal hook and the like, so as to limit the hanging hook 24 connected in the hanging point, and thus the connection of the elastic member 5 is completed.

[0153] Then, the connecting column 2 is inserted into the hole to realize the positioning of the connecting member 1, and after the positioning of the connecting member 1 is realized, when the height of the body of the climbing tool does not meet the requirement, the connecting column 2 is directly guided to slide downward relative to the surface in the length direction of the supporting leg 6, and is locked after sliding a set distance, that is, the penetrating end on the locking member 14 is penetrated through the penetrating through hole 15 and is positioned and inserted into a group of the locking holes 13 to realize the fixation. Thus, the height adjustment operation of the climbing tool is completed.

[0154] When disassembling, it is directly pulled out,

[0155] Under normal circumstances, the foot pan 3 is in a supporting state (i.e. working state) or a storage state, and therefore the following is exemplarily described when the foot pan 3 is in the supporting state.

[0156] That is, at this time, the connecting shaft 4 is at the upper stop point position, such as Figure 3 , Figure 5 , Figure 6 and Figure 10 . When the foot pan 3 is in the use state, the bottom end of the connecting column 2 is in abutment with the bottom of the abutment groove 12, so that the bottom of the supporting leg 6 has a larger stress area, and the abutment groove 12 has a certain depth, and therefore the connecting shaft 4 at this time is at the upper stop point.

[0157] Once it is needed to be stored, an external force is first applied to guide the connecting shaft 4 to slide from the upper stop point to the lower stop point, and when the lower stop point is reached, the bottom end of the connecting column 2 is at least flush with the lowest end of the deflection surface 23, and then the foot pan 3 is driven to rotate towards the inner side of the supporting leg 6 with the connecting shaft 4 as the rotation center, that is, by means of the arrangement of the deflection surface 23, when the connecting column 2 and the foot pan 3 move relative to each other, there is no obstacle in the movement track of the foot pan 3.

[0158] When the surface of the footbath member 3 in the length direction is parallel to the connecting column 2, the bottom of the opening 21 abuts against the surface of the connecting column 2, and the surface of the abutting strip 22 away from the bottom of the limiting groove 19 abuts against the surface of the connecting column 2. During the process that the connecting shaft 4 slides from the upper stop point to the lower stop point, the connecting shaft 4 drives the elastic member 5 to generate the elastic force for pulling the connecting shaft 4 back to the original position. Then, the external force is removed, the elastic member 5 pulls the connecting shaft 4 back to the original position to form the storage state of the footbath member 3. During the process, the footbath member 3 rotates towards the inner side of the supporting leg 6, so that the footbath member 3 does not protrude from the side of the climbing aid. The storage mode does not need to disassemble the footbath member 3, and the installation cost of repeated disassembly and assembly is reduced.

[0159] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
