Description

TECHNICAL FIELD

[0001] The utility model relates to a climbing device technical field, specifically to a climbing device with tool box, the climbing ladder can be herringbone ladder, one word ladder, climbing platform or car washing platform. BACKGROUND

[0002] The climbing device can be a climbing platform, a herringbone ladder or an escalator, one of the more typical devices is a climbing platform, and the climbing platforms on the market have different heights. The low height can be directly stepped on, the higher climbing platform has steps on the side, but no handrail tool, and there is no place to put tools on the existing climbing platform, so when the staff climbs the climbing platform, sometimes they carry tools to climb, which not only makes climbing difficult, but also has low safety due to the influence of tools, so sometimes they use handrail rods and other auxiliary components to assist in climbing.

[0003] For example, the patent document with application number CN201710532919.9 discloses a ladder and a harvester with the ladder, which has a foldable handrail that allows maintenance personnel to enter the grain box and avoid accidents when climbing over the engine. When not in use, it can be folded and stored below the height limit of the harvester, without affecting the operation of the harvester, ensuring the transportation and site operation of the harvester, and avoiding the damage of a series of components caused by excessive height.

[0004] Although the above-mentioned patent document provides a technical solution that can fold the handrail, it still has limitations in specific use, as follows:

[0005] First, the operator may carry a wrench, screwdriver or other tools when climbing, but when working at height, not only tools are used for work, sometimes carrying work is also needed, for example, carrying cross beams and other items. At this time, the user will put the tools carried in his pocket or on the surface of the climbing platform, but if the tools are heavy, the downward force on the clothes will be large, affecting the user's carrying and movement, and if they are placed on the climbing platform, they are easy to be stepped on, causing the user to fall.

[0006] Secondly, some handrails may choose to install a tool box to place tools, for example, the above-mentioned patent document provides a technical solution, if a tool box is installed on the handrail, when the handrail is folded, the tool box will present a large protrusion, affecting the overall storage of the equipment.

[0007] Therefore, how to solve the above-mentioned problems of the prior art has become the subject to be studied and solved by the utility model. INVENTION CONTENTS

[0008] The utility model provides a climbing device with tool box, aims at solving the technical problem of above -mentioned background art.

[0009] In order to achieve the above purpose, the utility model adopts the technical scheme of a kind of climbing device with tool box, climbing device includes the climbing platform of end position connection with support leg, handrail bar piece, connecting piece, elastic member and tool box;

[0010] The lower end of the handrail bar piece is rotatably connected to the side of the climbing platform, so that the handrail bar piece has a supporting state and a storage state.

[0011] The upper end of the handrail bar piece has an adjusting groove, and the connecting piece passes through the adjusting groove to rotatably connect the tool box and the handrail bar piece, so that the tool box has a working state and a folding state.

[0012] One end of the elastic member acts on the connecting piece, and the other end acts on the handrail bar piece.

[0013] When the tool box is in the working state, there is a set angle between the surface in the length direction of the tool box and the surface in the length direction of the handrail bar piece, and the elastic member is configured to limit the deflection tendency of the tool box.

[0014] To make the tool box in the folding state, overcome the limitation of the elastic member, and make the tool box relative to the handrail bar piece with the connecting piece as the center of rotation, until the surface in the length direction of the tool box is parallel to the surface in the length direction of the handrail bar piece, and the parallel state is maintained by the limitation of the elastic member.

[0015] In the above scheme, the relevant content is explained as follows:

[0016] In the above scheme, the climbing platform with support leg at the end is rotatably connected between the climbing platform and the support leg, for example, refer to Figure One and Figure Two , which shows the schematic diagram when the support leg is raised and folded.

[0017] In the above scheme, the lower end of the handrail bar piece is rotatably connected to the side of the climbing platform, so that the handrail bar piece has a supporting state and a storage state, specifically, refer to Figure One and Figure Two , the lower end of the handrail bar piece can be rotatably connected with the support leg through the rotating connecting piece, and located at the side of the climbing platform, secondly, it can also be directly rotatably connected at the side of the climbing platform through the rotating connecting piece.

[0018] In the above scheme, the upper end of the handrail rod and the tool box can be directly connected, and the elastic member mainly maintains the state of the tool box, so the adjusting groove can be directly a circular hole, the rotating connecting member is a long strip-shaped connecting rod, the upper end of the handrail rod is provided with an L-shaped cross-section clamping groove, one end of the connecting rod is rotatably connected to the bottom of the L-shaped clamping groove, and the other end is fixed to the end of the tool box. Under normal circumstances, the elastic member pulls the tool box to the working state, the connecting rod abuts against the bottom of the L-shaped clamping groove, and once folding is needed, the elastic member can be released or the tool box can be directly rotated to make the tool box clamped into the groove of the L-shaped clamping groove and arranged in parallel with the handrail rod. At this time, the inner wall of the groove of the L-shaped clamping groove is in interference fit with the tool box (specifically, the inner wall of the groove of the L-shaped clamping groove exerts a large friction force on the tool box, so that the tool box no longer flips over).

[0019] In the above scheme, one end of the elastic member acts on the connecting member, and the other end acts on the handrail rod. The connecting member can be hook-connected or welded with the handrail rod. The handrail rod can be hook-connected or welded with the connecting member, or connected through a sliding block (i.e. the sliding block is slidably arranged on the handrail rod. Once the elastic member needs to be tightened, the sliding block is only needed to be limited, and then the tool box is rotated to pull the tightened elastic member to stretch).

[0020] In the above scheme, the connecting member can be a rivet, a screw with a nut or a knob, or an I-shaped pin.

[0021] Further technical solutions, the upper end of the handrail rod has a cavity, and the elastic member is positioned in the cavity.

[0022] The elastic member is a tension spring.

[0023] With the above design, the elastic member will not be easily damaged by external debris.

[0024] Further technical solutions, the handrail rod includes a handrail rod body and an upper end cover, and the lower end of the handrail rod body is rotatably connected to the side of the support leg.

[0025] The upper end of the handrail rod body is positioned and connected with the upper end cover.

[0026] Since the above-mentioned technical solutions mainly rely on friction to limit the fixing of the tool box (which can also be assisted by screws and other components), but these methods have low automaticity in operation, and once the adjusting groove is cracked, the entire handrail rod needs to be replaced. In order to solve this problem, the upper end cover and the handrail rod body are matched to make the adjusting groove only on the upper end cover, and once the adjusting groove is cracked, only the upper end cover needs to be replaced.

[0027] Further, the adjusting slot is a long slot arranged on the surface of the upper end cover.

[0028] When the connecting member passes through the adjusting slot, the long slot is configured to guide the connecting member to slide along the length direction of the handrail rod body.

[0029] One end of the long slot has a first supporting surface, and the other end has a second supporting surface.

[0030] The first supporting surface and the second supporting surface can provide opposite vertical supports for the connecting member to limit the sliding distance of the connecting member in the long slot.

[0031] When the tool box is in the working state, the first supporting surface supports the connecting member to maintain the position of the tool box in the working state.

[0032] To make the tool box in the folded state, the connecting member is slid from the first supporting surface to the second supporting surface, the tool box and the opposite end of the upper end cover are away from each other to increase the rotation distance between the tool box and the upper end cover, and the tool box is deflected with the connecting member at the second supporting surface as the rotation center.

[0033] When the tool box is in the folded state, the surface in the length direction of the tool box is parallel to the surface in the length direction of the handrail rod body, and the tool box also abuts against the opposite end of the upper end cover.

[0034] With the above design, the tool box only needs to follow the connecting member to switch between the first supporting surface and the second supporting surface to realize the conversion operation between the working state and the folded state.

[0035] Further, the end side wall of the tool box has a lap joint slot matched with the upper end cover.

[0036] The side wall of the tool box is provided with a mounting hole for positioning the connecting member.

[0037] The mounting hole is correspondingly arranged with the adjusting slot.

[0038] Without the lap joint slot, in order to achieve the purpose of the tool box following the connecting member to switch between the first supporting surface and the second supporting surface, the tool box can only be arranged on the upper end side of the handrail rod body, and with the above design, the tool box can abut against the upper end of the handrail rod body.

[0039] Further, the top view of the handrail rod body and the upper end cover is a long rod-shaped structure.

[0040] With the above design, the appearance between the upper end cover and the handrail rod body is higher, and when the handrail rod body is overturned, it can be arranged parallel to the climbing platform.

[0041] Further technical solutions, the pre-tightening piece is a rivet, when the limiting block is inserted into the pre-tightening groove, the rivet is provided with a flip rivet at both ends as a limiting block limiting.

[0042] With the above design, the pre-tightening piece can limit the limiting block after installation without the help of auxiliary components (such as screws).

[0043] Further technical solutions, the side of the upper end cover has a protruding part, when the tool box is in a working state, the surface of the tool box in the length direction and the surface of the handrail rod in the length direction There is a set angle between them, the protruding part is configured to hold the tool box, so that the tool box remains in a state of a set angle with the handrail rod.

[0044] With the above design, the tool box is in a working state, and the stability is better, that is, the tool box is in a state of a set angle with the handrail rod It will be limited by the supporting force from the protruding part and the elastic piece.

[0045] Further technical solutions, when the tool box is in a working state;

[0046] The notch of the lap joint groove is downwardly and oppositely arranged with the upper end cover,

[0047] The groove bottom of the lap joint groove is upwardly;

[0048] The groove bottom of the lap joint groove has a first abutting surface and a second abutting surface;

[0049] The first abutting surface and the second abutting surface have a top support angle therebetween;

[0050] When the tool box is in a working state, the end surface of the end of the upper end cover abuts against the first abutting surface and the top support angle, and the side surface of the upper end cover abuts against the second abutting surface.

[0051] It should be noted that the top support angle can be L-shaped or Z-shaped as Figure 6 When the top support angle is Z-shaped, it has two corners, in order from top to bottom, the upper corner plays a role when the tool box abuts against the opposite end of the upper end cover, and the lower corner plays a role when the tool box is in a working state.

[0052] With the above design, the tool box can be fully matched with the lap joint groove to ensure the stability of the tool box.

[0053] Further technical solutions, the end of the elastic piece has a first hook, and the first hook is positioned and connected with the side wall of the connecting piece, so that the connecting piece remains in a position of the first support surface.

[0054] The other end of the elastic member has a second hook;

[0055] The second hook is connected with the handrail rod body.

[0056] By the above design, the elastic member can be quickly connected with the connecting member and the handrail rod member.

[0057] Further, the side wall of the handrail rod body is provided with a long strip-shaped pre-tightening groove.

[0058] The climbing device further comprises a pre-tightening member and a limiting block; the pre-tightening member is positioned and connected in the pre-tightening groove, the second hook is positioned and connected with the handrail rod body by acting on the side wall of the pre-tightening member, and when the second hook is positioned and connected with the pre-tightening member, the limiting block is configured to be inserted into the pre-tightening groove, so that the pre-tightening member is at the groove bottom of the long strip-shaped pre-tightening groove and stretches the elastic member.

[0059] Since the tool box is kept stable by the elastic member, if the elastic member is in a slack state during installation, the working state of the tool box cannot be guaranteed, and by the above design, the elastic member can be in a pre-tightening state, i.e., a pre-tightening state, during installation, and then the connecting member will always firmly abut against the first supporting surface.

[0060] Further, the upper end cover is in plug-in connection with the handrail rod body, and the cavity is arranged between the upper end cover and the handrail rod body.

[0061] The cavity has a plurality of limiting strips arranged along the length direction of the handrail rod body.

[0062] The plug-in end of the upper end cover has a plug-in groove corresponding to the limiting strips.

[0063] The limiting strips have guide holes corresponding to the pre-tightening grooves, and when the limiting block is inserted into the pre-tightening groove, the insertion end of the limiting block has a stabilizing portion inserted into the guide hole.

[0064] By the above design, the stability of the upper end cover during plug-in is high, and the firmness of the limiting block after insertion is better.

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

[0071] In this invention, the toolbox can be quickly switched between a working state and a folded state through the cooperation of the elastic element, the connector, and the adjustment groove. This allows users to place tools after climbing, and when not in use, it can be freely folded along with the handrail. Specifically, when the toolbox is in the working state, there is a set angle between the surface of the toolbox along its length and the surface of the handrail along its length. The elastic element is configured to limit the deflection tendency of the toolbox, so that the toolbox stops moving. To put the toolbox in the folded state, the limitation of the elastic element can be overcome, and the toolbox can move relative to the handrail around the connector as the rotation center until the surface of the toolbox along its length is parallel to the surface of the handrail along its length, and the parallel state is maintained by the limitation of the elastic element.

[0086] The language in this paper is only for describing specific embodiments, and is not intended to limit the case. The singular form such as "a", "this", "this", "this" and "the" is also included in the plural form as used in this paper.

[0087] Reference is made to the accompanying drawings Figures 1-11 ​​​​As shown, a climbing device with a tool box, the climbing device comprises a climbing platform 1 with a support leg connected at the end, a handrail rod 2, a connecting piece 3, an elastic piece 4 and a tool box 5;

[0088] The lower end of the handrail rod 2 is rotationally connected to the side of the climbing platform 1, so that the handrail rod 2 has a supporting state and a storage state;

[0089] The upper end of the handrail rod 2 has an adjusting groove 6, and the connecting piece 3 rotationally connects the tool box 5 and the handrail rod 2 through the adjusting groove 6, so that the tool box 5 has a working state and a folding state;

[0090] One end of the elastic piece 4 acts on the connecting piece 3, and the other end acts on the handrail rod 2;

[0091] When the tool box 5 is in the working state, there is a set angle between the surface in the length direction of the tool box 5 and the surface in the length direction of the handrail rod 2, and the elastic piece 4 is configured to limit the deflection tendency of the tool box 5;

[0092] In order to make the tool box 5 in the folding state, overcome the limitation of the elastic piece 4, and make the tool box 5 relative to the handrail rod 2 with the connecting piece 3 as the rotation center, until the surface in the length direction of the tool box 5 is parallel to the surface in the length direction of the handrail rod 2, and the parallel state is maintained through the limitation of the elastic piece 4.

[0093] In this embodiment, the climbing platform 1 with a support leg connected at the end, that is, the climbing platform 1 is rotationally connected with the support leg, for example, refer to Figure One and Figure Two which shows the schematic diagram of the support leg being raised and folded.

[0094] In this embodiment, the lower end of the handrail rod 2 is rotationally connected to the side of the climbing platform 1, so that the handrail rod 2 has a supporting state and a storage state, specifically, refer to Figure One and Figure Two The lower end of the handrail rod 2 can be rotationally connected with the support leg through the rotating connecting piece 3 and located at the side of the climbing platform 1, and secondly, it can also be directly rotationally connected to the side of the climbing platform 1 through the rotating connecting piece 3.

[0095] In this embodiment, the upper end of the handrail rod 2 can be directly connected with the tool box 5, and the elastic member 4 mainly plays a role in maintaining the state of the tool box 5, so the adjusting groove 6 can be directly a circular hole, the rotating connecting member 3 is a long strip-shaped connecting rod, the upper end of the handrail rod 2 is provided with an L-shaped cross-section clamping groove, one end of the connecting rod is rotatably connected with the bottom of the L-shaped clamping groove, and the other end is fixed to the end of the tool box 5. Under normal circumstances, the elastic member 4 pulls the tool box 5 to be in a working state, and the connecting rod abuts against the bottom of the L-shaped clamping groove. Once folding is needed, the elastic member 4 can be released or directly pulled to rotate the tool box 5, so that the tool box 5 is clamped into the groove of the L-shaped clamping groove and arranged in parallel with the handrail rod 2. At this time, the inner wall of the groove of the L-shaped clamping groove and the tool box 5 are in interference fit (specifically, the inner wall of the groove of the L-shaped clamping groove applies a large friction force to the tool box 5, so that the tool box 5 is no longer turned over).

[0096] In this embodiment, one end of the elastic member 4 acts on the connecting member 3, and the other end acts on the handrail rod 2. The connection between the elastic member 4 and the connecting member 3 can be a hook type connection or welding. The connection between the elastic member 4 and the handrail rod 2 can be a hook type connection or welding, or can be connected through a sliding block (i.e., the sliding block is slidably arranged on the handrail rod 2. Once the elastic member 4 needs to be tightened, the sliding block is only needed to be limited, and then the tool box 5 is rotated to pull the tightened elastic member 4 to stretch.

[0097] In the utility model, through the cooperation of the elastic member 4, the connecting member 3 and the adjusting groove 6, the tool box 5 can be quickly converted between the working state and the folding state, so that the user has space to place tools after climbing, and can also freely fold the tool box 5 with the handrail rod 2 when not in use. Specifically, when the tool box 5 is in the working state, the surface in the length direction of the tool box 5 and the surface in the length direction of the handrail rod 2 have a set angle, the elastic member 4 is configured to limit the deflection tendency of the tool box 5, so that the tool box 5 no longer moves. In order to make the tool box 5 in the folding state, the limitation of the elastic member 4 can be overcome, and the tool box 5 is relatively moved with the handrail rod 2 with the connecting member 3 as the rotating center, until the surface in the length direction of the tool box 5 is parallel to the surface in the length direction of the handrail rod 2, and the parallel state is maintained through the limitation of the elastic member 4.

[0098] Different from the tool box 5 storage mode in the prior art, the surface in the length direction of the tool box 5 is parallel to the surface in the length direction of the handrail rod 2 after the tool box 5 is stored in the embodiment, that is, on a straight line, and preferably a straight line, which is more conducive to storage. The specific storage can be referred to in the description of the tool box 5. Figure Two .

[0099] Further, the upper end of the handrail rod 2 has a cavity 27, and the elastic member 4 is positioned in the cavity 27.

[0100] The elastic member 4 is a tension spring.

[0101] If the elastic member 4 is outside the handrail rod body 7, foreign matters outside are easy to hit the elastic member 4, and the design can prevent the elastic member 4 from being easily damaged by foreign matters.

[0102] In a further technical solution, the handrail rod 2 comprises a handrail rod body 7 and an upper end cover 8, the lower end of the handrail rod body 7 is rotationally connected with the support leg side portion;

[0103] The upper end of the handrail rod body 7 is positionally connected with the upper end cover 8.

[0104] The fixing mode of the tool box 5 is mainly limited by friction (or auxiliary components such as screws), but the automaticity is not high during operation, and once the adjusting groove 6 is cracked, the entire handrail rod 2 needs to be replaced. In order to solve this problem, the upper end cover 8 is matched with the handrail rod body 7, so that the adjusting groove 6 is only on the upper end cover 8, and once the adjusting groove 6 is cracked, only the upper end cover 8 needs to be replaced.

[0105] In a further technical solution, the adjusting groove 6 is a long slot arranged on the surface of the upper end cover 8;

[0106] When the connecting member 3 passes through the adjusting groove 6, the long slot is configured to guide the connecting member 3 to slide along the length direction of the handrail rod body 7;

[0107] One end of the long slot has a first support surface 9, and the other end has a second support surface 10;

[0108] The first support surface 9 and the second support surface 10 can provide opposite vertical supports for the connecting member 3 to limit the sliding distance of the connecting member 3 in the long slot;

[0109] When the tool box 5 is in a working state, the first support surface 9 supports the connecting member 3 to maintain the position of the tool box 5 in the working state;

[0110] In order to make the tool box 5 in a folded state, the connecting member 3 is slid from the first support surface 9 to the second support surface 10, the opposite end of the tool box 5 and the upper end cover 8 are away from each other to increase the rotation distance between the tool box 5 and the upper end cover 8, and the tool box 5 is deflected with the connecting member 3 at the second support surface 10 as the rotation center.

[0111] When the tool box 5 is in a folded state, the surface of the tool box 5 in the length direction is parallel to the surface of the handrail rod body 7 in the length direction, and the tool box 5 also abuts against the opposite end of the upper end cover 8.

[0112] By means of the above design, the tool box 5 can realize the transformation operation between the working and folding states by following the connection piece 3 to transform between the first supporting surface 9 and the second supporting surface 10.

[0113] In order to realize the transformation operation of the tool box 5 between the working and folding states (since the tool box 5 is in one of the working and folding states before transformation, the working state is taken as an example for description), specifically:

[0114] When the tool box 5 is in the working state, the first supporting surface 9 supports the connection piece 3 to maintain the position of the tool box 5 in the working state;

[0115] If the tool box 5 needs to enter the folding state, at this time, the connection piece 3 is slid from the first supporting surface 9 to the second supporting surface 10, the tool box 5 and the opposite end of the upper end cover 8 are away from each other to increase the rotation distance between the tool box 5 and the upper end cover 8, the tool box 5 is deflected with the connection piece 3 at the second supporting surface 10 as the rotation center, when the deflection angle is set, the surface of the tool box 5 in the length direction is parallel to the surface of the handrail rod body 7 in the length direction, and the tool box 5 also abuts against the opposite end of the upper end cover 8, so that the tool box 5 is in the folding state.

[0116] Further technical solutions, the end wall of the tool box 5 has a lap joint groove 16 matched with the upper end cover 8;

[0117] The side wall of the tool box 5 is provided with a mounting hole 17 for positioning the connection piece 3;

[0118] The mounting hole 17 is correspondingly arranged with the adjusting groove 6.

[0119] In the absence of the lap joint groove 16, in order to complete the purpose of the tool box 5 following the connection piece 3 to transform between the first supporting surface 9 and the second supporting surface 10, the tool box 5 can only be arranged on the upper end side of the handrail rod body 7, and by means of the above design, the tool box 5 can abut against the upper end of the handrail rod body 7.

[0120] Further technical solutions, the handrail rod body 7 and the upper end cover 8 have a long strip-shaped rod structure in plan view.

[0121] By means of the above design, the appearance between the upper end cover 8 and the handrail rod body 7 is higher, and when the handrail rod body 7 is overturned, it can be arranged parallel to the climbing platform 1.

[0122] In a further technical solution, the side of the upper cover 8 has a protrusion 22. When the tool box 5 is in the working state, there is a set angle between the surface of the tool box 5 in the length direction and the surface of the handrail 2 in the length direction. The protrusion 22 is configured to support the tool box 5 so that the tool box 5 is kept at a set angle with the handrail 2.

[0123] With the above design, the tool box 5 is more stable when it is in working state. That is, when the tool box 5 is at a set angle to the handrail 2, it will be supported by the protrusion 22 and restricted by the elastic member 4.

[0124] A further technical solution is that when the toolbox 5 is in a working state;

[0125] The opening of the overlapping groove 16 faces downward and is positioned opposite to the upper end cover 8.

[0126] The bottom of the overlapping groove 16 faces upward;

[0127] The bottom of the overlapping groove 16 has a first abutting surface 23 and a second abutting surface 24;

[0128] A top support angle 25 is provided between the first abutment surface 23 and the second abutment surface 24;

[0129] When the toolbox 5 is in working condition, the end face of the upper cover 8 abuts against the first abutting surface 23 and the top support angle 25, and the side of the upper cover 8 abuts against the second abutting surface 24.

[0130] It should be noted that the top support angle 25 can be L-shaped or... Figure 6 The Z-shaped toolbox shown has two corners when the top support angle 25 is Z-shaped. In order from top to bottom, the upper corner plays a role when the toolbox 5 and the upper cover 8 are in contact at opposite ends, and the lower corner plays a role when the toolbox 5 is in the working state.

[0131] The above design allows the tool box 5 to fully cooperate with the overlapping groove 16, ensuring the stability of the tool box 5.

[0132] Specifically, such as Figure 6 As shown, the top support angle 25 is Z-shaped. When the tool box 5 is in working condition, the end face of the upper cover 8 abuts against the lower corner of the first abutting surface 23 and the top support angle 25. At the same time, the protrusion 22 is configured to support the tool box 5 so that the tool box 5 is kept at a set angle with the handrail 2, which makes the tool box 5 more stable.

[0133] like Figure 7 andFigure 8 As shown, when the tool box 5 is in the folded state, the end face of the end of the upper end cover 8 is in abutment with the second abutment surface 24 and the upper corner of the top support corner 25, and the side surface of the upper end cover 8 opposite to the side where the protrusion 22 is arranged is in abutment with the first abutment surface 23.

[0134] Further, the end of the elastic member 4 is provided with a first hook 11, which is in positioning connection with the side wall of the connecting member 3, so that the connecting member 3 has a tendency to be kept in the position where the first support surface 9 is located.

[0135] The other end of the elastic member 4 is provided with a second hook 12.

[0136] The second hook 12 is connected with the handrail rod body 7.

[0137] With the above design, the elastic member 4 can be quickly connected with the connecting member 3 and the handrail rod member 2.

[0138] Further, the side wall of the handrail rod body 7 is provided with a long strip-shaped pre-tightening groove 13.

[0139] The climbing device further comprises a pre-tightening member 14 and a limiting block 15; the pre-tightening member 14 is in positioning connection in the pre-tightening groove 13, and the second hook 12 is in positioning connection with the handrail rod body 7 by acting on the side wall of the pre-tightening member 14; after the second hook 12 is in positioning connection with the pre-tightening member 14, the limiting block 15 is configured to be inserted into the pre-tightening groove 13, so that the pre-tightening member 14 is at the groove bottom of the long strip-shaped pre-tightening groove 13 and stretches the elastic member 4.

[0140] Since the tool box 5 is kept stable by the elastic member 4, if the elastic member 4 is in a relaxed state during installation, the working state of the tool box 5 cannot be guaranteed, and with the above design, the elastic member 4 can be in a pre-tightening state, i.e., a pre-tightened state, during installation, and then the connecting member 3 will always firmly abut against the first support surface 9.

[0141] Specifically, the tool box 5 is connected with the upper end cover 8 through the connecting member 3, and then the first hook 11 is hooked on the side wall of the connecting member 3; then the pre-tightening member 14 is inserted into the pre-tightening groove 13, and the second hook 12 is in positioning connection with the handrail rod body 7 by being hooked on the side wall of the pre-tightening member 14; at this time, the elastic member 4 is not in the pre-tightening state, i.e., the pre-tightening member 14 abuts against the upper end of the pre-tightening groove 13. Then, after the upper end cover 8 is abutted, the limiting block 15 can be directly inserted into the pre-tightening groove 13; at this time, the pre-tightening member 14 is at the groove bottom of the long strip-shaped pre-tightening groove 13 and stretches the elastic member 4, so that the elastic member 4 is pre-tightened.

[0142] Further, the pre-tightening member 14 is a rivet, and when the limiting block 15 is inserted into the pre-tightening groove 13, the rivet is provided with a rivet head 18 at both ends for limiting the limiting block 15.

[0143] With the above design, the pre-tightening member 14 can limit the limiting block 15 after installation without the aid of auxiliary components such as screws.

[0144] Further, the upper end cover 8 is in plug-in connection with the handrail rod body 7, and the cavity 27 is arranged between the upper end cover 8 and the handrail rod body 7.

[0145] The cavity 27 is provided with a plurality of limiting strips 19 arranged along the length direction of the handrail rod body 7.

[0146] The plug-in end of the upper end cover 8 is provided with a plug-in groove 20 corresponding to the limiting strip 19.

[0147] The limiting strip 19 is provided with a guide hole 21 corresponding to the pre-tightening groove 13, and when the limiting block 15 is inserted into the pre-tightening groove 13, the insertion end of the limiting block 15 is provided with a stabilizing portion 26 inserted into the guide hole 21.

[0148] With the above design, the stability of the upper end cover 8 during plug-in is high, and the firmness of the limiting block 15 after insertion is better.

[0149] Specifically, the cavity 27 can be only a cavity arranged between the upper end cover 8 and the handrail rod body 7, or can be a structure as shown in the drawings. Figures 6-8

[0150] When the plug-in end of the upper end cover 8 is inserted into the hollow cavity 27 in the handrail rod body 7, the plug-in groove 20 cooperates with the limiting strip 19 to quickly stabilize the upper end cover 8.

[0151] When the limiting block 15 is inserted into the pre-tightening groove 13, although the pre-tightening groove 13 can cooperate with the rivet head 18 to limit one end of the limiting block 15, the other end of the limiting block 15 is prone to shaking. In order to solve this problem, the stabilizing portion 26 of the limiting block 15 is inserted into the guide hole 21 to achieve the limiting purpose of the limiting block 15.

[0152] Working principle:

[0153] The following is an example of installation and transformation operation:

[0154] ​When installing, first connect the tool box 5 with the upper end cover 8 through the connecting piece 3, and then hang the first hook 11 on the side wall of the connecting piece 3, and then insert the pre-tightening piece 14 into the pre-tightening groove 13, and the second hook 12 is positioned and connected with the handrail rod body 7 by hooking on the side wall of the pre-tightening piece 14, at this time, the elastic piece 4 is not in the pre-tightening state, that is, the pre-tightening piece 14 abuts against the upper end of the pre-tightening groove 13.

[0155] Then, the insertion end of the upper end cover 8 is inserted into the upper end of the handrail rod body 7, at this time, the insertion groove 20 cooperates with the limiting strip 19, which can quickly and stably position the upper end cover 8, and then the limiting block 15 is directly inserted into the pre-tightening groove 13, at this time, the pre-tightening piece 14 is at the groove bottom of the long strip-shaped pre-tightening groove 13 and stretches the elastic piece 4, so that the elastic piece 4 is pre-tightened.

[0156] Subsequently, the upper end cover 8 and the handrail rod body 7 can be fixedly connected through screws and the like.

[0157] When changing, since the tool box 5 is in one of the working and folding states before changing, the working state of the tool box 5 is taken as the standard for description.

[0158] When the tool box 5 is in the working state, the first supporting surface 9 supports the connecting piece 3 to maintain the position of the tool box 5 in the working state.

[0159] That is, at this time, the elastic piece 4 pulls the connecting piece 3 to abut against the first supporting surface 9, and there is a set angle between the surface in the length direction of the tool box 5 and the surface in the length direction of the handrail rod 2, and the lapping groove 16 abuts against the upper end cover 8.

[0160] If the tool box 5 needs to enter the folding state, at this time, the connecting piece 3 is slid from the first supporting surface 9 to the second supporting surface 10, the tool box 5 and the opposite end of the upper end cover 8 are away from each other to increase the rotating spacing between the tool box 5 and the upper end cover 8, and the tool box 5 is deflected with the connecting piece 3 at the second supporting surface 10 as the rotating center, when a set angle is deflected, the surface in the length direction of the tool box 5 is parallel to the surface in the length direction of the handrail rod body 7, the tool box 5 is released, the elastic piece 4 pulls the connecting piece 3 to abut against the first supporting surface 9, at this time, the opposite end of the tool box 5 abuts against the upper end cover 8, so that the tool box 5 is in the folding state.

[0161] The above embodiments are only for illustrating the technical concept and characteristics of the present application, the purpose is to enable those skilled in the art to understand the content of the present application and to 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.
