Description

Technical Field

[0001] The utility model relates to the technical field of foldable drawbars, in particular to a foldable drawbar case with a foldable cover plate. Background Art

[0002] A foldable suitcase is a common tool for people to carry items, which greatly facilitates people's lives. When not in use, the foldable suitcase can be folded to reduce the storage volume, so that users can store the foldable suitcase.

[0003] The prior art still has the following deficiencies:

[0004] 1. The cover of the current folding box often falls down after being opened, thereby affecting the user's taking or storing items and causing inconvenience to the user.

[0005] 2. The cover of the current folding box is usually a whole. When there are too many items in the trolley case, or the items are long, the items will extend from the top of the box, resulting in the cover being unable to fully cover the upper part of the box and unable to play a good shielding role.

[0006] 3. When there are too many items in the box or the items are too long, the items will lift up the cover, and the lifted cover is more likely to collide and injure people when moving.

[0007] 4. When the folding suitcase is folded, the cover plate on the top of the suitcase is usually placed inside or outside the suitcase in different ways to facilitate the folding of the suitcase. However, the current folding method of the cover plate will leave a gap between the cover plate and the suitcase when the cover plate moves to the side of the suitcase, which makes the cover plate not firmly placed. The cover plate is easy to shake and collide with the suitcase, causing damage to the suitcase or noise. Summary of the invention

[0062] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0063] [Example 1]

[0064] like Figure 1-Figure 5 A foldable trolley case with a foldable cover is shown, comprising a foldable case body 1 and a pull rod 13 arranged on the case body 1, a receiving cavity for receiving articles is formed inside the case body 1, an opening 14 connected to the receiving cavity is formed at the upper end of the case body 1, and the opening 14 is used to store articles in the receiving cavity or take articles out of the receiving cavity.

[0065] A cover mechanism 2 is also provided above the box body 1, and the cover mechanism 2 is used to close the opening 14 to protect the items in the accommodating cavity of the box body 1. When the user opens the cover mechanism 2, the items can be stored in or taken out of the box body 1.

[0066] The cover mechanism 2 comprises:

[0067] A fixing plate 21, which is detachably arranged on the upper end of the box body 1 through a connecting piece 24;

[0068] One end of the support plate assembly 3 is connected to the fixing plate 21 , and the other end is a free end of the support plate assembly 3 .

[0069] A movable connection is formed between the support plate assembly 3 and the fixing plate 21, so that the free end of the support plate assembly 3 can rotate.

[0070] When unfolded, the support plate assembly 3 can cover the opening 14 of the box body 1, thereby achieving the purpose of closing the upper end of the box body 1 and protecting the items in the accommodating cavity.

[0071] When the box body 1 is folded, the support plate assembly 3 can rotate relative to the fixed plate 21, so that the support plate assembly 3 is arranged on the side of the box body 1. This is convenient for users to fold the box body, and there is no need to store the cover plate mechanism 2 separately, and it will not take up too much space when storing the foldable trolley case.

[0072] like Figure 1-Figure 3 As shown, the support plate assembly 3 includes a plurality of support plates 31 arranged side by side, and these support plates 31 are connected to each other.

[0073] The support plate 1 31 located at the end is connected to the fixing plate 21 , so that the support plate assembly 3 can rotate relative to the fixing plate 21 .

[0074] Specific as Figure 2 and Figure 3 As shown, the cover plate mechanism 2 also includes a connecting elastic band 4 , which includes a fixed end 41 and a connecting end 42 , and the connecting end 42 is fixed on the lower end surface of the support plate assembly 3 .

[0075] In this embodiment, the connection end 42 is fixed under the support plate 31, so that a plurality of support plates 31 form a flexible connection through the connection end 42 connected to the elastic band 4.

[0076] The support plate 31 can be connected to the connecting elastic band 4 through a fixing nail 45, and the fixing nail 45 is preferably a square head nail.

[0077] The fixed end 41 is formed with a ring portion 43, which can be sleeved on the fixed plate 21 to achieve a flexible connection between the fixed plate 21 and the support plate assembly 3. The user can open the upper end of the box body 1 by lifting the support plate assembly 3, so as to store items into the interior of the box body 1 or take items out from the interior of the box body 1.

[0078] Specific as Figure 5As shown, the support plate 1 31 connected into one body by the connecting elastic band 4 can move freely, and the connecting elastic band 4 can be stretched. Therefore, the user can partially open the support plate 1 31 without fully opening the support plate assembly 3 to expose the opening 14, which is convenient for the user to take or store items. At the same time, the folded support plate 1 31 can press the connecting elastic band 4 by its own weight to prevent the connecting elastic band 4 from shrinking, and drive the support plate 1 31 to cover the top of the opening 14 again.

[0079] Specific as Figure 2 As shown, a hook 44 is provided on the end of the connection end 42 , and a hanging rod 12 is formed on the box body 1 . The hook 44 can cooperate with the hanging rod 12 to fix the connection end 42 on the box body 1 .

[0080] When too many or too long articles are loaded in the box 1 , the upper ends of these articles will lift up the support plate assembly 3 covering the upper end of the box 1 , so that the support plate assembly 3 cannot cover the top of the box 1 well.

[0081] When the technical solution in this embodiment is adopted, after the hook 44 is connected to the hanging rod 12 on the box body 1, the two ends of the elastic band 4 can be fixedly connected in cooperation with the fixing plate 21.

[0082] Since the support plates 31 are all fixed on the connection ends 41 of the connecting elastic bands 4, and the connecting elastic bands 4 can be elastically deformed, when an object pushes up the support plate assembly 3 from below, the connecting elastic bands 4 are stretched, and the support plates 31 arranged on the connecting elastic bands 4 can move away from each other as the connecting elastic bands 4 are stretched. Since the two ends of the connecting elastic bands 4 are respectively fixed by the fixing plate 21 and the hanging rod 12, the connecting elastic bands 4 still have a movement tendency to drive the support plates 31 arranged thereon to move toward the upper end of the box body 1. Thus, when too many or too long objects are placed in the box body 1, the support plate assembly 3 can still remain in a state of covering the upper end of the box body 1, and maintain the stability of the use state.

[0083] As a preferred embodiment, a sub-buckle is provided on the end of the connecting end 42 , and a female buckle is provided on the box body 1 . The sub-buckle can cooperate with the female buckle to lock, so that the connecting end 42 is fixed on the box body 1 .

[0084] Furthermore, a locking piece structure may be provided on the end of the connection end 42 , and a corresponding locking structure may be provided on the side wall of the box body 1 , so that the locking piece structure can cooperate with the locking structure to fix the connection end 42 on the box body 1 .

[0085] The fixing plate 21 and the support plate assembly 3 are made of solid wood. Solid wood has sufficient structural strength and is easy to process and transform, which reduces the process of assembly. When the support plate assembly 3 is placed on the box body 1, the solid solid wood can also better support the weight of the user.

[0086] The fixing plate 21 can also be made of a hollow aluminum plate or a plastic plate.

[0087] [Example 2]

[0088] This embodiment is basically the same as the first embodiment, except that:

[0089] like Figure 4 As shown, in this embodiment, the support plate assembly 3 includes only one support plate 2 32 , and one end of the support plate 2 32 is connected to the fixing plate 21 .

[0090] When the suitcase is in a closed state, the free end of the second support plate 32 abuts against the upper end of the front shell 11 of the box body 1, so that the second support plate 32 can cover the upper part of the opening 14;

[0091] When the suitcase is in an open state, the free end of the second support plate 32 can be rotated to abut against the extended pull rod 13, thereby exposing the opening 14.

[0092] When the second support plate 32 covers the opening 14 , the user can sit on the second support plate 32 to rest.

[0093] [Example 3]

[0094] This embodiment is basically the same as the first embodiment, except that:

[0095] like Figure 6-Figure 9 As shown, in this embodiment, the support plate 1 31 and the fixing plate 21 are hingedly connected by a hinge structure. The hinge structure can be a hinge structure arranged at the upper ends of the support plate 1 31 and the fixing plate 21.

[0096] In this embodiment, specifically Fig.10 and Fig.11 As shown, the hinge structure is a hinge seat 5

[0097] A hinge hole 23 is formed on the side of the fixing plate 21;

[0098] A second hinge hole 34 is formed on the side surface of the support plate 1 31 of the support plate assembly 3 .

[0099] The hinge seat 5 is formed with two plugs 51, which can be inserted into the hinge hole 1 23 or the hinge hole 2 34. The two ends of the hinge seat 5 are respectively connected to the hinge hole 1 23 and the hinge hole 2 34, so that the support plate assembly 3 and the fixed plate 21 are hinged to each other.

[0100] Furthermore, a central hole 55 is formed on the plug 51 . The central hole 55 passes through the plug 51 , and is used for passing the fixing bolt 6 .

[0101] When the material of the support plate 1 31 is solid wood, the fixing bolt 6 can be partially fixed in the support plate assembly 3 or the fixing plate 21 , and the plug 51 can rotate around the fixing bolt 6 .

[0102] Furthermore, at least two abutting portions 52 are formed at the end of the plug 51 , and a deformation inclined surface 53 and an abutting surface 54 are formed on the abutting portion 52 .

[0103] A shrinkage reserved groove 56 is formed between the abutting portions 52 .

[0104] When the fixing plate 21 and the supporting plate 1 31 are made of hollow aluminum plates or plastic plates, a cavity for accommodating the abutting portion 52 can be easily formed in the fixing plate 21 and the supporting plate 1 31 , and the hinge hole 1 23 or the hinge hole 2 34 is connected to the cavity.

[0105] When the plug 51 is inserted into the hinge hole 1 23 or the hinge hole 2 34 , the hinge hole 1 23 or the hinge hole 2 34 will contact the abutment portion 52 , and the outer periphery of the hinge hole 1 23 or the hinge hole 2 34 will abut against the deformation slope 53 , thereby pushing the plug 51 to move in the contraction reserved groove 56 , so as to facilitate the plug 51 to enter the hinge hole 1 23 or the hinge hole 2 34 .

[0106] When the plug 51 enters the hinge hole 1 23 or the hinge hole 2 34 , the abutment portion 52 is reset so that the abutment surface 54 can abut against the inner periphery of the hinge hole 1 23 or the hinge hole 2 34 , preventing the abutment portion 52 from detaching from the hinge hole 1 23 or the hinge hole 2 34 .

[0107] The center hole 55 leads to the shrinkage reserved groove 56, so that when the hinge seat 5 is assembled, it can be fixed with the fixing bolt 6.

[0108] However, when the hinge seat 5 is directly disposed on the sides of the fixing plate 21 and the support plate assembly 3, the hinge seat 5 is actually protruding from the sides of the fixing plate 21 and the support plate assembly 3. In daily use, this state can easily cause the hinge seat 5 to be hit by external force, and the hinge seat 5 is separated from the fixing plate 21 and the support plate assembly 3, affecting the normal use of the user.

[0109] Furthermore, a groove 1 22 is formed on the fixing plate 21, and a groove 2 33 is formed on the supporting plate 1 31, so that the hinge seat 5 can be hidden in the groove 1 22 and the groove 2 33. This prevents the hinge seat 5 protruding from the fixing plate 21 and the supporting plate assembly 3 from being knocked off by external force.

[0110] As another preferred technical solution, the support plates 31 can also be hinged using a hinge seat 5.

[0111] When the foldable suitcase is stored or transported in a folded form, the support plate assembly 3 can be shielded outside the front shell 11 of the box body 1, thereby preventing the front shell 11 from being damaged.

[0112] [Example 4]

[0113] like Fig.10 and Fig.11 As shown, this embodiment is basically the same as the first embodiment, except that:

[0114] The support plate assembly 3 in this embodiment adopts the structure of a second support plate 32 , and the second support plate 32 is connected to the fixed plate 21 through a hinge seat 5 .

[0115] When the user needs to place or take out an item in the accommodating cavity, the user can lift up the second support plate 32 and make the second support plate 32 rest against the extended pull rod 13, thereby preventing the second support plate 32 from falling and reclosing the opening 14.

[0116] [Example 5]

[0117] This embodiment is basically the same as the first embodiment, except that:

[0118] like Fig.12 As shown, a magnetic attraction member 35 is disposed in the free end of the support plate assembly 3 .

[0119] A screw hole 16 is formed at the upper end of the front shell 11 of the box body 1 , and an iron screw 15 is arranged in the screw hole 16 .

[0120] When the support plate assembly 3 is needed to close the opening of the box body 1, the support plate assembly 3 can be lowered so that the support plate assembly 3 covers the upper end of the opening 14. At this time, the magnetic member 35 is aligned with the iron screw 15, so that the magnetic member 35 can be adsorbed on the iron screw 15, thereby achieving the purpose of fixing the position of the column support plate assembly 3.

[0121] When the suitcase is in a folded state and the support plate assembly 3 adopts a structure in which several support plates 31 are arranged side by side, the magnetic element 35 can be adsorbed on the iron screw 15 to fix the folded state of the support plate assembly 3 and prevent the folded support plate assembly 3 from unfolding again.
