Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of article storage, especially relates to a folding basket and a storage cabinet with a vacuum bag. BACKGROUND

[0002] The folding basket can be flexibly applied to multiple scenes such as temporary storage of clothes and storage of sports equipment due to the large capacity advantage. The folding basket has a folding structure for realizing self-folding. For example, most of the existing folding baskets are designed by hingedly connecting four side plates and a bottom plate. When the folding basket needs to be folded, the four side plates are turned upside down on the bottom plate to realize volume compression after folding. However, the existing folding basket only has a folded state and an unfolded state. The frame body in the folded state cannot be used, and can only be used in the unfolded state. When some users want to place some small items, the frame body has a large volume when unfolded, the items cannot be fully placed, and space is occupied. UTILITY MODEL CONTENT

[0003] To solve the problems in the prior art, a folding basket capable of controlling the size of the folding basket body is provided.

[0004] The utility model adopts the following technical scheme to be realized: a folding basket, comprising:

[0005] A top frame in a ring-shaped hollow structure;

[0006] A bottom plate arranged in parallel below the top frame and used for supporting articles;

[0007] An elastic deformation support mechanism arranged between the top frame and the bottom plate, comprising: a plurality of compressible support components arranged in a circumferential direction to form a side wall support structure of the folding basket; and an elastic member for driving each support component to maintain the maximum unfolded height in a normal state;

[0008] An elastic potential energy constraint mechanism for fixing the distance between the top frame and the bottom plate during compression;

[0009] The elastic deformation support mechanism and the elastic potential energy constraint mechanism constitute a linkage system. The compression deformation of the compressible support component is triggered by applying a vertical pressure, and the height of the top frame is locked through the elastic potential energy constraint mechanism, so that the folding basket forms a stable compression storage mode.

[0010] In actual use, when the user needs a large-volume large-capacity folding basket, the folding basket in normal state is directly used, at this time the elastic member drives the support assembly to maintain the maximum unfolded height of the folding basket; when a small-volume small-capacity folding basket is needed, the user can press the top frame downward to apply vertical pressure to the top frame to overcome the elastic force of the elastic member on the support assembly, so that the distance between the top frame and the bottom plate is reduced, and when the user feels that the volume at this time is appropriate, the pressing of the top frame can be stopped. At this time, the user can lock the height of the top frame through the elastic potential energy restraining mechanism, so that the folding basket maintains the volume at this time.

[0011] The linkage system composed of the elastic deformation support mechanism and the elastic potential energy restraining mechanism can adjust the height position of the top frame, so that the user can select a folding basket with a volume size that the user is satisfied with, and meet different storage needs.

[0012] As a preferred embodiment, the support assembly is an X-shaped folding lever frame, the upper and lower ends of the X-shaped folding lever frame are hingedly connected with the top frame and the bottom plate to form two hinged parts respectively; the connection part of the top frame and the bottom plate with at least one hinged part is provided with a sliding groove extending in the horizontal direction, and the hinged part is slidingly fitted in the sliding groove.

[0013] The X-shaped folding lever frame is cross-hinged, and the hinge part is provided with the elastic member, and the elastic member is a torsion spring.

[0014] The height of the top frame is adjusted by folding the X-shaped folding lever frame, the X-shaped folding lever frame is expanded by the torsion spring arranged at the hinge part of the X-shaped folding lever frame, and the sliding groove can limit the adaptive deformation of the X-shaped folding lever frame and limit the limit state of the X-shaped folding lever frame when it is unfolded or folded. And after the X-shaped folding lever frame is compressed, a side wall structure with small gap is formed, so that small objects can be placed in the whole folding basket.

[0015] As a preferred embodiment, the elastic potential energy restraining mechanism comprises a restraining band that can be wound or fixed between the top frame and the bottom plate, and a protrusion arranged on the side wall of the top frame and the bottom plate.

[0016] The restraining band is in the form of a strip, and a plurality of buckle holes are arranged on the restraining band in the length direction, and the protrusion can be buckled into the buckle hole to lock the distance between the top frame and the bottom plate; or

[0017] The restraining band is in the form of a line, and the restraining band can be wound on the protrusions of the top frame and the bottom plate at the same time to lock the distance between the top frame and the bottom plate.

[0018] The protrusion can facilitate the fixation of the restraining band on the top frame and the bottom plate. When the distance between the top frame and the bottom plate reaches the position that the user is satisfied with, the restraining band can be buckled with the protrusions on the side walls of the top frame and the bottom plate at the same time, thereby locking the distance between the top frame and the bottom plate.

[0019] As a preferred, the elastic potential energy constraint mechanism comprises a constraint belt provided with a ratchet strip extending along its own length direction; the lower end of the constraint belt is fixedly connected with the bottom plate, the side wall of the top frame is provided with a frame body for the constraint belt to pass through, the frame body is provided with an elastic pawl, and the ratchet strip of the constraint belt is engaged with the elastic pawl.

[0020] The user can pull the constraint belt so that the elastic pawl is engaged with the ratchet strip at different positions, and the engagement of the elastic pawl with the ratchet strip enables the constraint belt to be pulled in one direction only; when it is necessary to unlock, the user can move the elastic pawl so that the elastic pawl is disengaged from the ratchet strip.

[0021] As a preferred, the elastic potential energy constraint mechanism further comprises protrusions arranged on the side walls of the top frame and the bottom plate; the constraint belt is linear, and the constraint belt can be wound on the protrusions of the top frame and the bottom plate at the same time to complete the spacing locking between the top frame and the bottom plate.

[0022] The protrusions facilitate the winding of the constraint belt on the top frame and the bottom plate. When the spacing between the top frame and the bottom plate reaches a position satisfactory to the user, the constraint belt can be wound on the protrusions on the side walls of the top frame and the bottom plate at the same time to complete the spacing locking between the top frame and the bottom plate.

[0023] As a preferred, at least one set of the X-shaped folding lever frame is matched with the elastic potential energy constraint mechanism, and the elastic potential energy constraint mechanism comprises:

[0024] A ratchet wheel arranged at the hinge center of the X-shaped folding lever frame, and the wheel shaft of the ratchet wheel is coaxially arranged with the hinge shaft;

[0025] A detachable cover, and the inner cavity of the cover is provided with a pawl and an elastic force element;

[0026] When the cover is buckled on the hinge center of the X-shaped folding lever frame, the pawl is engaged with the ratchet wheel under the action of the elastic element to form locking, and the engagement between the pawl and the ratchet wheel is released after the cover is detached.

[0027] The user can directly press the top frame to make the height of the top frame decrease, and the cooperation of the ratchet wheel and the pawl can realize the one-way rotation of the X-shaped folding lever frame, i.e. the X-shaped folding lever frame can only be folded but cannot be unfolded. When the user needs to reset the X-shaped folding lever frame, the cover can be detached from the hinge center, which is very convenient. The hinge center in the above X-shaped folding lever frame can be provided with a torsional spring and a ratchet wheel. Since all the X-shaped folding lever frames are synchronously unfolded or folded, the hinge centers of two sets of X-shaped folding lever frames can be separately provided with ratchet wheels and not provided with torsional springs, or the hinge centers of the other two sets of X-shaped folding lever frames can be separately provided with torsional springs and not provided with ratchet wheels.

[0028] As preferred, the hinge part is a sliding block which is fitted in a sliding groove and is hingedly connected with the end of the X-shaped folding rod holder; at least one set of X-shaped folding rod holder is matched with the elastic potential energy constraint mechanism, which comprises:

[0029] A ratchet is arranged on the sliding groove and extends along the length direction of the sliding groove;

[0030] A plug is detachably fixed on the sliding block, and the plug is provided with a pawl and an elastic force element;

[0031] The sliding block is provided with an insertion slot for inserting the plug, and the sliding block is provided with a notch at the position corresponding to the ratchet, and the notch is communicated with the insertion slot; when the plug is fitted on the sliding block, the pawl is exposed from the notch and engaged with the ratchet; the engagement between the pawl and the ratchet is released when the plug is detached.

[0032] The user can directly press the top frame to lower the height of the top frame, and the cooperation between the pawl and the ratchet can realize the one-way sliding of the X-shaped folding rod holder, i.e. the X-shaped folding rod holder can only be folded but cannot be unfolded. When the user needs to reset the X-shaped folding rod holder, the plug can be detached from the sliding block, which is very convenient. The detachable fixing of the plug and the sliding block can be achieved by tight fitting, buckle fixing, magnetic attraction fixing, etc.

[0033] As preferred, the top frame and the bottom plate are provided with vertically extending abutting convex columns at the corners of the opposite sides, and when the abutting convex columns of the top frame and the bottom plate abut against each other, the top frame and the bottom plate are at the minimum distance;

[0034] The elastic potential energy constraint mechanism comprises an insertion section which is arranged on the abutting convex column of the top frame or the bottom plate and extends vertically, and the insertion section is provided with a plurality of cooperation holes which are arranged at intervals in the vertical direction; compared with the abutting convex column on the opposite side of the insertion section, the insertion section is fitted in a insertion hole, and the side wall of the insertion hole is provided with an elastic clamping element which is used for clamping in the cooperation hole.

[0035] Through the above arrangement, the top frame can be prevented from being excessively pressed and damaging the elastic deformation support mechanism; meanwhile, the insertion section and the insertion hole are arranged on the abutting convex column, the cooperation holes are arranged on the insertion section, and the elastic clamping element is arranged in the insertion hole; when the elastic clamping element is clamped in the insertion hole, the height of the top frame will not rebound, thereby realizing the one-way movement. The unlocking of the elastic clamping element can adopt any existing structure which can realize the disengagement of the elastic clamping element from the cooperation hole, for example, the elastic clamping element is an elastic pin shaft, and the unlocking can be realized by pulling the elastic pin shaft outward.

[0036] As preferred, at least one stabilizing frame is further arranged between the top frame and the bottom plate, the stabilizing frame is arranged in parallel with the top frame and the bottom plate, and the upper and lower ends of the stabilizing frame are connected with the top frame and the bottom plate through the elastic deformation supporting mechanism; the stabilizing frame forms a compressible linkage structure with the top frame and the bottom plate through the elastic deformation supporting mechanism.

[0037] The setting of the stabilizing frame can make the whole folding basket larger, so that the user can select more folding baskets with suitable volume size.

[0038] As preferred, the supporting assembly is a telescopic column, the telescopic column is internally provided with the elastic member, and the telescopic column comprises an outer tube and an inner tube; the elastic potential energy restraining mechanism comprises a plurality of locking holes arranged on the side wall of the outer tube and vertically spaced, and an elastic protrusion arranged on the side wall of the inner tube; when the telescopic column is compressed, the elastic member is compressed, the elastic protrusion generates a radial contraction displacement, and is gradually clamped into the locking holes to complete locking.

[0039] The cooperation of the telescopic column and the elastic member can naturally expand the top frame. When the telescopic column is compressed to a certain length, the elastic protrusion at this time can extend into the locking hole to complete locking, and when unlocking is needed, the top frame can be directly pulled up by force, so that the elastic protrusion generates a radial contraction displacement and is separated from the locking hole.

[0040] A storage cabinet comprises the folding basket and a vacuum bag, the vacuum bag is arranged between the top frame and the bottom plate and located at the inner side of the elastic deformation supporting mechanism, the bottom of the vacuum bag is fixedly connected with the bottom plate, the opening periphery of the top frame is fixedly connected with the bag opening of the vacuum bag through welding or bonding, so that the opening of the top frame serves as the outline of the bag opening of the vacuum bag, the top frame is detachably fixed with a cover plate for blocking the opening of the top frame, and the cover plate or the vacuum bag is provided with an air nozzle for connecting with a vacuum equipment.

[0041] When the cover plate blocks the opening of the top frame, the vacuum bag forms a sealed chamber; when the vacuum bag is vacuumed, the elastic deformation supporting mechanism slowly descends under the action of atmospheric pressure, so that the whole folding basket is compressed, and the elastic potential energy restraining mechanism can avoid the folding basket from resetting under the action of the elastic deformation supporting mechanism after the vacuum bag leaks.

[0042] By matching the folding basket with the vacuum bag, the upper and lower ends of the vacuum bag are fixed with the top frame and the bottom plate, so that the top frame and the bottom plate can support the whole bag body, thereby facilitating the placing of clothes or bedding. After the clothes or bedding are placed, the vacuum bag can be subjected to vacuumizing operation, so that the vacuum bag is shrunk to drive the folding basket to be folded. The folding basket has an overall frame to provide three-dimensional support and protection for the vacuum bag, which prevents the bag body from being deformed under pressure and guarantees the regularity of the storage space. Moreover, the vacuum bag may leak after being stored for a long time, and at this time, the elastic potential energy constraint mechanism can prevent the folding basket from recovering after the vacuum bag leaks, so as to ensure that the whole storage cabinet is always in a compressed storage state.

[0043] Compared with the prior art, the utility model has the beneficial effects that: through the linkage system formed by the elastic deformation support mechanism and the elastic potential energy constraint mechanism, the user can adjust the height position of the top frame, can select the folding basket with the volume size that the user is satisfied with, and meets different storage needs.

DETAILED DESCRIPTION

[0066] The utility model will be further described below according to the drawings and specific examples.

[0067] As Figures 1 to 3 ​​​As shown, the present scheme discloses a folding basket, which comprises a top frame 1, a bottom plate 2 and an elastic deformation supporting mechanism arranged between the top frame 1 and the bottom plate 2. The supporting assembly of the elastic deformation supporting mechanism is four groups of X-shaped folding rod frames 3. The four groups of X-shaped folding rod frames 3 form the side walls of the folding basket and support the top frame 1. The elastic member of the elastic deformation supporting mechanism is a torsion spring (not shown in the figure). The torsion spring is arranged at the hinge center 31 of the X-shaped folding rod frame 3. The torsion spring drives the X-shaped folding rod frame 3 to maintain the maximum expanded height in the normal state. The top frame 1 is in a ring-shaped hollow structure, and the cross-sectional shape of the circumferential outer edge and the circumferential inner edge is rectangular. The bottom plate 2 is arranged below the top frame 1 and is arranged in parallel with the top frame 1 for supporting articles.

[0068] The upper and lower ends of the X-shaped folding rod frame 3 are hinged to the top frame 1 and the bottom plate 2 to form two hinge parts respectively. The connection between the top frame 1 and the bottom plate 2 and one or two hinge parts is provided with a sliding groove 21 extending in the horizontal direction. The hinge part is a pin shaft 22 hingedly connected with the end of the X-shaped folding rod frame 3, and the pin shaft 22 is slidingly fitted in the sliding groove 21.

[0069] The corners of the opposite sides of the top frame 1 and the bottom plate 2 are provided with vertically extending abutting convex columns 11. When the abutting convex columns 11 of the top frame 1 and the bottom plate 2 abut against each other, the distance between the top frame 1 and the bottom plate 2 is at the minimum, and at this time the volume of the folding basket is in the minimum state.

[0070] The folding basket further comprises an elastic potential energy restraining mechanism for fixing the distance between the top frame 1 and the bottom plate 2 in the compression stroke. The elastic deformation supporting mechanism and the elastic potential energy restraining mechanism constitute a linkage system. By applying a vertical pressure, the compression deformation of the compressible X-shaped folding rod frame 3 is triggered, and the height locking of the top frame is realized through the elastic potential energy restraining mechanism, so that the folding basket forms a stable compression storage form.

[0071] As shown in the figure, Figure 10 The top frame 1 and the bottom plate 2 are further provided with a stable frame 7 arranged in parallel with the top frame 1 and the bottom plate 2. The upper and lower ends of the stable frame 7 are connected with the top frame 1 and the bottom plate 2 through the X-shaped folding rod frame 3, and the stable frame 7 is also provided with a sliding groove 21 matched with the end of the X-shaped folding rod frame 3. The stable frame 7 forms a compressible linkage structure with the top frame 1 and the bottom plate 2 through the elastic deformation of the X-shaped folding rod frame 3.

[0072] Embodiment 1

[0073] As shown in the figure, Figure 4 and Figure 5As shown, the elastic potential energy restraining mechanism in Embodiment 1 includes restraining belts 4 and protrusions 41 arranged on the circumferential side walls of the top frame 1 and the bottom plate 2, the protrusions 41 extending in the horizontal direction. The restraining belts 4 can be in the form of strips, and a plurality of buckle holes 42 are arranged on the restraining belts 4 at intervals along the length direction of the belts 4, and the protrusions 41 can be buckled into the buckle holes 42 to complete the spacing locking between the top frame 1 and the bottom plate 2.

[0074] Alternatively, the restraining belts 4 are in the form of lines, and the restraining belts 4 can be wound on the protrusions 41 of the top frame 1 and the bottom plate 2 at the same time to complete the spacing locking between the top frame 1 and the bottom plate 2.

[0075] Alternatively, the restraining belts 4 are provided with ratchet strips (not shown in the figure) extending along the length direction of the belts 4; the lower end of the restraining belts 4 is fixedly connected with the bottom plate 2, and a frame body (not shown in the figure) for the restraining belts 4 to pass through is arranged on the side wall of the top frame 1, and the frame body is provided with elastic pawls, and the ratchet strips of the restraining belts 4 are engaged with the elastic pawls. The user can pull the restraining belts 4, so that the elastic pawls are engaged with the ratchet strips at different positions, and the engagement of the elastic pawls with the ratchet strips makes the restraining belts 4 be pulled in one direction only, and when it is necessary to unlock, the user can move the elastic pawls to make the elastic pawls disengage from the ratchet strips.

[0076] Embodiment 2

[0077] As shown in Figure 6 and Figure 7 In Embodiment 2, among the four groups of X-shaped folding lever racks 3, two groups of X-shaped folding lever racks 3 are matched with elastic potential energy restraining mechanisms, which include: ratchets 5 arranged at the hinge centers 31 of the X-shaped folding lever racks 3, each X-shaped folding lever rack 3 includes two folding levers hingedly connected inside and outside, and the center of the folding lever located on the inside is fixedly provided with a ratchet 5, and the wheel shaft of the ratchet 5 is coaxially arranged with the hinge shaft; the center of the folding lever located on the outside is matched with a detachable shell 32, and the inner cavity of the shell 32 is provided with a pawl 51, and the pawl 51 can be elastically and plastically deformed, so the pawl 51 is provided with an elastic force element, and in other embodiments, a spring (elastic force element) can be matched with the pawl 51. The shell 32 can be sleeved and matched with the center of the folding lever on the outside in a tight fitting manner, and a circumferentially arranged protrusion (not shown in the figure) can be arranged between the shell 32 and the center of the folding lever to limit the rotation of the shell 32. When the shell 32 is buckled on the hinge center 31 of the X-shaped folding lever rack 3, the pawl 51 and the ratchet 5 form an engagement locking, and at this time the folding basket can only be compressed but cannot be reset. When the shell 32 is detached to disengage the pawl 51 from the ratchet 5, the folding basket can be reset.

[0078] Embodiment 3

[0079] As shown in Figures 10 to 16As shown, the stabilizing frame 7 in this embodiment 3 is provided with a groove 21, and the groove wall of the groove 21 is provided with ratchet teeth 6 extending along its length. The hinge part of the X-shaped folding rod frame 3 is provided with a slider 8, which is slidably fitted in the groove 21. The slider 8 includes a sliding section 811 that extends into the groove 21 and slides in cooperation with the groove 21. The slider 8 is also provided with an insertion groove 81 that passes through the sliding section 811. The upper and lower ends of the sliding section 811 are provided with notches 82 that communicate with the insertion groove 81. The two notches 82 correspond to the ratchet teeth 6 on the upper and lower groove walls of the groove 21. The end of the sliding section 811 is provided with a fixing buckle 812 that passes through the groove 21 to restrict the position of the entire slider 8, so that the slider 8 will not detach from the groove 21. The slider 8 is also provided with two convex shafts 33 that are spaced apart vertically. The end of the folding rod of the X-shaped folding rod frame 3 is sleeved on the outside of the convex shafts 33 and hinged to the convex shafts 33.

[0080] The insert block 83 has a laterally extending insertion section 831, which is inserted into the groove 81. The upper and lower ends of the insertion section 831 are provided with pawls 51. The pawls 51 can be elastically deformed, so the pawls 51 have their own elastic force application element. The pawls 51 protrude from the notch 82 and engage with the ratchet 6.

[0081] The upper and lower ends of the insert block 83 are provided with latches 84, and the slider 8 is provided with latching holes 841 corresponding to the positions of the latches 84 to engage with the latches 84. When the insert block 83 is engaged with the slider 8, the pawl 51 protrudes from the notch 82 side and engages with the ratchet 6. At this time, the slider 8 can only slide in one direction within the groove 21. When the insert block 83 is removed from the slider 8, the slider 8 can slide in both directions.

[0082] like Figure 8 and Figure 9 As shown, Figure 8 and Figure 9 A ratchet 6 can also be provided in the groove 21 of the top frame 1 and / or the bottom plate 2. The ratchet 6 can be provided on the inner side wall of the groove 21 or on the outer side wall of the groove 21. The design of the slider 8 and the insert 83 is the same as... Figures 10 to 16 The design approach used is the same, so it will not be repeated here.

[0083] In the use of Embodiments 1, 2, and 3, when storing large items, the folding basket in its natural state can be used directly. When storing small items or when the folding basket does not want to take up a lot of space, downward pressure can be applied to the top frame 1, reducing the gap between the top frame 1 and the bottom plate 2, thereby reducing the overall volume of the folding basket and preventing it from returning to its original shape. At this time, the gap between the X-shaped folding rods 3 will also decrease, making it easier to store small items. When you want the folding basket to return to its original shape, simply remove the restraint straps 4, the cover 32, or the insert block 83, and the folding basket will automatically return to its maximum size.

[0084] As Figures 17 to 19 shown, the present scheme discloses a storage cabinet, comprising the above-mentioned folding basket and a vacuum bag 9. The folding basket constitutes the framework of the entire storage cabinet, and the vacuum bag 9 is arranged between the top frame 1 and the bottom plate 2 and inside the X-shaped folding rod frame 3. The bottom of the vacuum bag 9 is fixedly connected with the bottom plate 2 by hot melt welding or easy-to-pull buckle connection.

[0085] The opening periphery of the top frame 1 is fixedly connected with the bag opening of the vacuum bag 9 by welding or bonding, so that the opening of the top frame 1 serves as the outline of the bag opening of the vacuum bag 9. The top frame 1 is detachably fixed with a cover plate 12 that blocks the opening of the top frame 1. The periphery of the cover plate 12 is pivotally connected with a buckle plate 13, which is buckled on the edge of the top frame 1 to realize sealing cooperation. At the same time, a sealing ring can be added between the cover plate 12 and the top frame 1 to realize sealing. A gas nozzle 14 for connecting with a vacuum pump is arranged on the cover plate 12.

[0086] In use, clothes or bedding to be stored are placed in the vacuum bag 9, and then the cover plate 12 is covered and buckled by the buckle plate 13. Then the vacuum pump is connected with the gas nozzle 14 to vacuum the vacuum bag. The X-shaped folding rod frame 3 slowly descends under the action of atmospheric pressure, so that the entire folding basket is folded, thereby achieving the purpose of storing the storage cabinet. And the folding basket has the elastic potential energy restraining mechanism of embodiment 1 or embodiment 2 or embodiment 3, so that even if the vacuum bag 9 leaks air later, the entire folding basket still maintains a compressed state.

[0087] Embodiment 4

[0088] As Figure 20 shown, the difference between the present embodiment 4 and embodiment 1 is that the elastic potential energy restraining mechanism is arranged on the abutting convex column 11. The lower end of the abutting convex column 11 of the top frame 1 is provided with a downward extending insertion section 111, and the abutting convex column 11 of the bottom plate 2 is provided with an upward opening insertion hole (not shown in the figure) for the insertion of the insertion section 111. A plurality of vertically spaced cooperating holes 112 are arranged on the side wall of the insertion section 111, and an elastic clamping piece is arranged in the insertion hole. The elastic clamping piece is an existing elastic pin shaft, which can be elastically stretched to be clamped into the cooperating hole, so that the height position between the top frame 1 and the bottom plate 2 is locked. The elastic pin shaft can be unlocked by any existing pressing or pulling method, so as to release the state of being clamped into the cooperating hole. For example, an opening is arranged through the side wall of the abutting convex column 11, and the elastic pin shaft is fixed in the opening. The user can pull the elastic pin shaft to make it separate from the cooperating hole.

[0089] Embodiment 5

[0090] As Figure 21As shown, the difference between the present embodiment 5 and embodiment 1 is that the support assembly is a telescopic column 100, which is arranged at the four abutting convex columns 11 of the top frame 1 and the bottom plate 2, and the telescopic column 100 comprises an outer tube 102 inserted into the upper and lower abutting convex columns 11, and an inner tube 101 sleeved by the two outer tubes 102. The outer tube 102 and the inner tube 101 are slidably fitted along the vertical direction, and a spring is arranged in the telescopic column 100 to expand the telescopic column 100.

[0091] The elastic potential energy restraint mechanism comprises a plurality of locking holes 104 arranged on the side wall of the lower outer tube 102 and vertically spaced, and an elastic protrusion 103 arranged on the side wall of the inner tube 101; when the telescopic column 100 is compressed, the compression spring is compressed, the elastic protrusion 103 is in contact with the lower outer tube 102, and a radial contraction displacement is generated, and is gradually clamped into the locking hole 104 to complete the locking.

[0092] Among them, the inner wall of the outer tube 102 is also provided with an arc-shaped avoiding groove 105 corresponding to the movement path of the elastic protrusion 103, which extends in the vertical direction to avoid the elastic protrusion 103, so that the elastic protrusion 103 can extend into the outer tube 102, avoiding the telescopic column 100 from being jammed when telescoping.
