Technical Field

[0001] The utility model relates to the technical field of paperboard supports, in particular to a paperboard container with a bottom support piece. Background Art

[0002] A cardboard container is a paper container used for packaging, transporting or storing items, usually made of two or more layers of cardboard material. In order to prevent the bottom of the cardboard container from collapsing or deforming when carrying items, support members are used to support the bottom of the cardboard container.

[0003] At present, the support frames of the supports on the market are mostly fixed, so their application scope is relatively limited. These supports can only effectively support paper containers containing items of a certain size and weight. However, when supporting paper containers containing items of different sizes or uneven weight distribution, the fixed support frame may not provide sufficient local support, making the paper container prone to deformation or breakage at the stress point, increasing the risk of damage to the items.

[0004] Therefore, in order to solve the above problems, a paperboard container with a bottom support member is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a paperboard container with a bottom support member, which has the advantages of being able to flexibly adjust the distance of the support frame, and solves the problem that the traditional support member is not very applicable.

[0006] To achieve the above object, the utility model provides the following technical solution: a cardboard container with a bottom support comprises a base, a moving assembly and a box body, wherein the moving assembly is installed at the center of the upper surface of the base along the transverse direction of the base;

[0007] The moving assembly includes two mounting plates, a forward and reverse screw is rotatably connected between the two mounting plates, and a first slider and a second slider are respectively meshed and slidably engaged on the threads on both sides of the forward and reverse screw;

[0008] The upper surfaces of the first sliding block and the second sliding block are both provided with support frames;

[0009] The upper ends of the two support frames are provided with grooves, and the lower end of the box body is clamped in the grooves;

[0010] A handle is arranged on one end surface of the forward and reverse screw rods.

[0011] Furthermore, the two mounting plates are installed at intervals on both sides of the upper surface of the base along the transverse direction of the base, and the two mounting plates are both installed with bearings penetrating through the base along the transverse direction.

[0012] Furthermore, the outer walls at both ends of the forward and reverse screws are respectively connected to the inner walls of the two bearing inner rings, and the forward and reverse screws are rotatably connected to the two mounting plates through the two bearings.

[0013] Furthermore, two limit rods are installed between the two mounting plates and are respectively located on both sides of the forward and reverse screw rods. The two limit rods both penetrate the first slider and the second slider, and the first slider and the second slider are both slidably connected to the limit rods.

[0014] Furthermore, springs are installed on two opposite inner side surfaces of the groove, and fixing plates are installed on the ends of the two springs close to each other, and the box body is clamped between the two fixing plates.

[0015] Furthermore, two slide grooves are provided on the upper surface of the base along the longitudinal direction of the base and are respectively located on both sides of the forward and reverse screw rods. Two positioning rods are installed at intervals at the bottom end of the support frame, and the lower ends of the two positioning rods slide in the two slide grooves respectively.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] The cardboard container with a bottom support member utilizes a moving component installed on the upper surface of the base, and controls the forward and reverse screws through a handle to perform clockwise and counterclockwise bidirectional rotation, so that the spacing between the first slider and the second slider can be adjusted, and then the two support frames can adjust their positions according to the actual situation of the items carried by the box body to support the box body, thereby enhancing the flexibility and stability of the device and reducing the risk of damage to the box body and items.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 In this embodiment, a cardboard container with a bottom support member uses a moving component 2 installed on the upper surface of a base 1, and controls the forward and reverse screws 23 to rotate clockwise and counterclockwise through a handle 5, so that the spacing between the first slider 24 and the second slider 25 can be adjusted, and then the two support frames 3 can adjust their positions according to the actual situation of the box body 6 carrying items, and support the box body 6, thereby enhancing the flexibility and stability of the device and reducing the risk of damage to the box body 6 and items.

[0024] Specifically, a paperboard container with a bottom support member in this embodiment includes a base 1, a moving component 2 and a box body 6, wherein the moving component 2 is installed at the center of the upper surface of the base 1 along the transverse direction of the base 1;

[0025] The moving assembly 2 includes two mounting plates 21, a forward and reverse screw rod 23 is rotatably connected between the two mounting plates 21, and a first slider 24 and a second slider 25 are respectively meshed and slidably engaged on the threads on both sides of the forward and reverse screw rod 23;

[0026] The upper surfaces of the first slider 24 and the second slider 25 are both equipped with a support frame 3;

[0027] The upper ends of the two support frames 3 are provided with grooves, and the lower ends of the box body 6 are clamped in the grooves;

[0028] A handle 5 is mounted on one end surface of the forward and reverse screw rods 23 .

[0029] In actual use, the user can drive the forward and reverse screws 23 to rotate clockwise and counterclockwise by rotating the handle 5 clockwise and counterclockwise; the forward and reverse screws 23 rotate, so that the first slider 24 and the second slider 25 can move respectively within the travel range of the side threads on the forward and reverse screws 23, and the first slider 24 and the second slider 25 move in opposite directions. The forward and reverse screws 23 rotate in both directions, so that the first slider 24 and the second slider 25 can reciprocate in opposite directions within the travel range of the side threads on the forward and reverse screws 23. Therefore, the forward and reverse screws 23 rotate in both directions so that the first slider 24 and the second slider 25 can be close to and away from each other on the forward and reverse screws 23, thereby allowing the spacing between the two support frames 3 to be adjusted to adapt to the box 6 carrying different items and to provide more effective support for the box 6.

[0030] Two mounting plates 21 are installed at intervals on both sides of the upper surface of the base 1 along the transverse direction of the base 1 , and bearings 22 are installed on both mounting plates 21 along the transverse direction of the base 1 .

[0031] The outer walls at both ends of the forward and reverse screw rods 23 are respectively connected to the inner walls of the inner rings of the two bearings 22 , and the forward and reverse screw rods 23 are rotatably connected to the two mounting plates 21 through the two bearings 22 .

[0032] Two limiting rods 26 are installed between the two mounting plates 21 and are respectively located on both sides of the forward and reverse screw rods 23 . The two limiting rods 26 both penetrate the first slider 24 and the second slider 25 . The first slider 24 and the second slider 25 are both slidably connected to the limiting rods 26 .

[0033] Under the restriction of the limit rod 26, when the forward and reverse screw rods 23 rotate, the first slider 24 and the second slider 25 can make linear motion on the forward and reverse screw rods 23, thereby preventing the first slider 24 and the second slider 25 from rotating during movement and causing damage to the support frame 3.

[0034] Springs 31 are installed on the two opposite inner sides of the groove, and fixing plates 32 are installed on the ends of the two springs 31 that are close to each other, and the box body 6 is clamped between the two fixing plates 32.

[0035] The elasticity of the spring 31 can ensure that the fixing plate 32 can adaptively clamp the box 6. Regardless of the slight difference in the size of the box 6, the spring 31 can automatically adjust its strength so that the fixing plate 32 fits the box 6 closely to achieve stable support. The spring 31 provides an elastic space between the two fixing plates 32, thereby avoiding the difficulty in installing the box 6 due to the fixed space of the support frame 3, and also preventing the box 6 from loosening during the clamping process.

[0036] Two slide grooves 4 are provided on the upper surface of the base 1 along the longitudinal direction of the base 1 and are respectively located on both sides of the forward and reverse screw rods 23 . Two positioning rods 33 are installed at intervals at the bottom end of the support frame 3 . The lower ends of the two positioning rods 33 slide in the two slide grooves 4 respectively.

[0037] The positioning rod 33 can further support the support frame 3 , thereby enhancing the stability of the support frame 3 .

[0038] The working principle of the above embodiment is:

[0039] The user can drive the forward and reverse screws 23 to rotate clockwise and counterclockwise by bidirectionally rotating the handle 5 clockwise and counterclockwise; the bidirectional rotation of the forward and reverse screws 23 allows the first slider 24 and the second slider 25 to move closer to and farther away from each other on the forward and reverse screws 23, thereby allowing the spacing between the two support frames 3 to be adjusted to accommodate the box 6 carrying different items and to provide more effective support for the box 6; the spring 31 provides an elastic space between the two fixing plates 32, thereby avoiding the difficulty in installing the box 6 due to the spatial fixation of the support frame 3, and also preventing the box 6 from loosening during the clamping process.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
