Description

Technical Field

[0001] The present invention relates to the technical field of storage boxes, and in particular to a telescopic storage box. Background Art

[0002] A box for putting things in, that is, collecting things together, is called a storage box. Compared with placing things scattered, using a storage box can limit the location of items and collect them, making it easier to place and carry them as a whole.

[0003] However, if a storage box wants to store more things, it needs a larger volume, which results in the storage box taking up a lot of space. If the storage box uses soft materials or a folding structure to achieve deformable placement, the storage box placement problem can be solved to a certain extent. However, the structural strength of this type of storage box is low, the stability is poor, and it is unable to bear a large internal weight and protect the internal items.

[0004] Therefore, how to improve and upgrade the existing storage box to overcome the above problems is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0009] Specifically, the longitudinal locking mechanism includes a positioning block and a longitudinal locking buckle. The positioning blocks of the longitudinal locking mechanism are arranged at equal intervals in the snap-in groove of the side panel. The longitudinal locking buckle is laterally slidably arranged in the outer sliding cavity of the side panel. The longitudinal locking buckle is provided with a longitudinal locking head, which can be snapped between two adjacent positioning blocks of the longitudinal locking mechanism.

[0010] Specifically, at least one group of the transverse locking mechanisms is provided on the telescopic plate assembly located on the inner side of the side panel and the telescopic plate assembly located on the outer side of the side panel, and the transverse locking mechanism includes positioning blocks and transverse locking buckles. The positioning blocks of the transverse locking mechanism are arranged at equal intervals in the positioning grooves on the side panels, and the transverse locking buckles are longitudinally slidably arranged in the inner sliding cavity on the side panels. The transverse locking buckles are provided with transverse locking heads, which can be clamped between two adjacent positioning blocks of the transverse locking mechanism.

[0011] As an improvement, the longitudinal locking mechanism also includes a longitudinal lock seat, the longitudinal lock buckle is slidably arranged in the longitudinal lock seat, the two ends of the longitudinal lock seat are provided with fixing claws, and the longitudinal lock buckle is provided with a reset inclined plate to prevent the longitudinal lock buckle from sliding out of the longitudinal lock seat.

[0012] As an improvement, the transverse locking mechanism also includes a transverse lock seat, the transverse lock buckle is slidably arranged in the transverse lock seat, the two ends of the transverse lock buckle are clamped with return springs, and the transverse lock head is an isosceles trapezoid.

[0013] Specifically, the connection between the top cover and the side panels is a hinge connection, the telescopic main panel on the outside of the top cover and the telescopic sub-panel on the outside of the top cover are provided with hooks, and the side panels are provided with rotating shafts that cooperate with the hooks.

[0014] As an improvement, a limiting block is provided at one end of the snap-in groove of the top cover and the positioning groove of the top cover, and a T-shaped clamping block cooperating with the limiting block is provided on the inner sliding cavity of the top cover and the outer sliding cavity of the top cover, and outer limiting plates are extended downward at both ends of the telescopic plate assembly located on the outer side of the top cover, and inner limiting plates are extended downward at both ends of the telescopic plate assembly located on the inner side of the top cover, and the outer limiting plates cover the inner limiting plates.

Compared with the bottom plate and the top cover, the side panels also need to have vertical sliding deformation. In order to reduce the space occupied by the sliding structure and prevent the vertical sliding from interfering with the sliding deformation of the side panels themselves and increase the structural strength of the storage box, the vertical sliding deformation structure is combined and arranged at the connection between the side panels. The structural strength and stability of the storage box will be reduced after the multi-layer sliding structure is unfolded. Therefore, a locking mechanism is added to reinforce and limit the sliding structure to prevent the storage box from deforming at will. The top cover and the side panels are detachably connected to break through the volume upper limit, and the top cover and the side panels are cooperatively connected to each other so that the top cover can deform with the side panels.

[0033] The present invention will be further described below in conjunction with the accompanying drawings:

[0034] like Figures 1 to 9 As shown, Figure 1The storage box is in a fully unfolded state. A preferred embodiment of the present invention comprises a side panel 1, a bottom panel 2 and a top cover 3. The storage box body is rectangular, has a stable structure and is convenient for extension. One side of the top cover 3 is detachably rotatably connected to the top of one of the side panels 1. The bottom panel 2 and the side panel 1 are fixedly connected by injection molding. The side panels 1, the bottom panel 2 and the top cover 3 all comprise two sets of telescopic plate assemblies 4 symmetrically arranged inside and outside. The two ends of the telescopic plate assembly 41 located on the inner side are provided with snap-fitting grooves 411, and the two ends of the telescopic plate assembly 42 located on the outer side are provided with outer sliding cavities 421 matching the snap-fitting grooves 411, so as to realize the storage box. The storage box can be telescoped in the vertical direction. The telescopic plate assembly 4 includes a telescopic main plate 43 and a telescopic sub-plate 44. The telescopic sub-plate 44 is provided with a guide groove 441 and a positioning groove 442. The telescopic main plate 43 is provided with an inner sliding cavity 431 that cooperates with the guide groove 441 and the positioning groove 442 to realize the telescoped and extended in the horizontal direction of the storage box. When the storage box is fully telescoped and opened in three directions, the original volume can be increased to 6 to 7 times at most. A longitudinal locking mechanism 5 is provided between two adjacent side plates 1, and a transverse locking mechanism 6 is provided on the side plate 1, which is used to limit and reinforce the storage box.

[0035] The longitudinal locking mechanism 5 includes a positioning block 7, a longitudinal locking seat 51 and a longitudinal locking buckle 52. The positioning blocks 7 of the longitudinal locking mechanism 5 are arranged at equal intervals in the clamping groove 411 of the side plate 1. The longitudinal locking buckle 52 is slidably set in the longitudinal locking seat 51. The longitudinal locking seat 51 has fixing claws 53 at both ends. The longitudinal locking seat 51 is fixed in the outer sliding cavity 421 of the side plate 1 through the claws 53. A reset inclined plate 54 is provided on the longitudinal locking buckle 52. The reset inclined plate 54 abuts against the outer sliding cavity 421 of the side plate 1 to prevent the longitudinal locking buckle 52 from sliding out of the longitudinal locking seat 51. The longitudinal locking buckle 52 is transversely slidably set in the longitudinal locking buckle 52. A longitudinal locking head 55 is provided on the longitudinal locking buckle 52, which can be clamped between two adjacent positioning blocks 7 of the longitudinal locking mechanism 5.

[0036] At least one group of transverse locking mechanisms 6 are provided on the telescopic plate assembly 41 located on the inner side of the side panel 1 and the telescopic plate assembly 42 located on the outer side of the side panel 1. The transverse locking mechanism 6 includes a positioning block 7, a transverse locking seat 61 and a transverse locking buckle 62. The positioning blocks 7 of the transverse locking mechanism 6 are arranged at equal intervals in the positioning groove 442 of the side panel 1. The transverse locking buckle 62 is longitudinally slidably arranged in the transverse locking seat 61. A transverse locking head 63 is provided on the transverse locking buckle 62, which can be clamped between two adjacent positioning blocks 7 of the transverse locking mechanism 6. Return springs 621 are clamped at both ends of the transverse locking buckle 62. The transverse locking head 63 is an isosceles trapezoid. A lower pressing groove 622 is provided on the transverse locking buckle 62. A lower pressing plate 623 extends outward from the bottom of the lower pressing groove 62, so that the transverse locking buckle 62 can be manually pressed down to unlock when it is stuck. The lower pressing plate 623 can increase the force bearing area.

[0037] The positioning block 7 is in a T-shape, which can better position and clamp the lock head to prevent the lock head from falling off.

[0038] The connection between the top cover 3 and the side panel 1 is a hinge connection. A hook 31 is provided on the outer telescopic main board 43 of the top cover 3 and the outer telescopic sub-board 44 of the top cover 3. The hook 31 will not affect the sliding and telescopic movement of the outer telescopic main board 43 of the top cover 3 and the outer telescopic sub-board 44 of the top cover 3. A rotating shaft 11 cooperating with the hook 31 is provided on the side panel 1.

[0039] A limit block 32 is provided at one end of the top cover 3 clamping groove 411 and the top cover 3 positioning groove 442, and a T-shaped clamping block 33 cooperating with the limit block 32 is provided on the inner sliding cavity 431 of the top cover 3 and the outer sliding cavity 421 of the top cover 3. When the outer telescopic sub-plate 44 of the top cover 3 and the inner telescopic sub-plate 44 of the top cover 3 slide out to the maximum, the T-shaped clamping block 33 can clamp the limit block 32 to prevent sliding, and the two ends of the telescopic plate assembly 42 located on the outside of the top cover 3 extend downward with an outer limit plate 34, and the two ends of the telescopic plate assembly 41 located on the inside of the top cover 3 extend downward. An inner limit plate 35 is extended, and an outer limit plate 34 covers the inner limit plate 35. Since the telescopic plate assembly 42 of the top cover 3 located on the outside is hingedly connected to the side plate 1, the sliding deformation of the telescopic plate assembly 42 of the top cover 3 located on the outside will also follow the sliding deformation of the side plate 1. Through the covering and clamping of the inner limit plate 35 by the outer limit plate 34, the telescopic plate assembly 41 of the top cover 3 located on the inside can follow the movement of the telescopic plate assembly 42 of the top cover 3 located on the outside, and the inner and outer limit plates 34 can provide a more stable covering effect on the box body.

[0040] The main body of the guide groove 441 has a U-shaped cross section, and a fixing plate 443 extends outward from one side of the guide groove 441. The asymmetric design can reduce installation errors.

[0041] The top of the outer telescopic sub-plate 44 of the side panel 1 is bent outward to clamp the outer telescopic main plate 43 of the side panel 1 to increase the structural stability. A handle 8 and a fixing ring 9 are provided on the outer telescopic main plate 43 of the side panel 1. The handle 8 facilitates the removal and deformation of the box body, and the fixing ring 9 is fixed with other items. The handle 8 is rotatably connected to the outer telescopic main plate 43 of the side panel 1, so that it is convenient to rotate to the surface of the box body for storage.

[0042] like Fig.10 As shown, this form is the initial form of the storage box. In this state, the storage box is small in size and convenient to place.

[0043] like Fig.11 As shown, this form is the form of the storage box after it is unfolded in one direction. The figure only shows one of the unfolding methods, which is suitable for placing long items. If you need to place higher items, you can also open it in the vertical direction.

[0044] like Fig.12 As shown, this form is the form of the storage box after it is unfolded in two directions, and the figure only shows one of the unfolding methods.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
