Description

Technical Field

[0001] This utility model relates to the field of mounting platform technology, and in particular to a mounting structure for a paper roll holder. Background Technology

[0002] In daily life, tissues are generally divided into two types: rolls and packaged tissues. Rolls, lacking individual outer packaging, are generally more affordable than individually packaged tissues. However, due to their cylindrical shape, rolls tend to roll and unroll, causing inconvenience. Therefore, reusable tissue boxes are used to hold the rolls. These boxes typically contain posts or clamps to restrict the roll's position without hindering its rolling, as shown in patent CN222929678U, and similar designs. Figure 2 The clamping structure inside the tissue box is shown. This clamping structure can be flipped outwards for easy insertion of a roll of tissue paper, and can also return to its original position under the action of a first spring, maintaining a tight grip on the inserted roll of tissue paper.

[0003] However, the existing elastic clamps in tissue boxes are inconvenient to install due to the action of the first spring, especially when the screw and the post that restricts the first spring are located on the inside and outside of the tissue box respectively. One side needs to be held down while the other side is being installed, resulting in low installation efficiency and a high risk of errors. Therefore, a convenient installation structure for elastic clamps is needed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide an installation structure for a paper roll holder.

[0005] To solve the above problems, the present invention adopts the following solution: An installation structure for a paper roll holder includes a base for supporting a carton shell; wherein the base is provided with a limiting hole for inserting the paper roll holder; the overall shape of the limiting hole corresponds to the shape of the paper roll holder; mounting holes for inserting a connecting post and a first spring are provided on both sides of the limiting hole; a limiting head for limiting the first spring is provided at one end of the connecting post; when the paper roll holder is placed into the limiting hole, the wing structures extending laterally on both sides of the paper roll holder abut against the mounting holes, and the connecting post passes through the first spring and the wing structures on the paper roll holder and is fixedly connected to the carton shell.

[0006] Furthermore, the base is provided with two limiting holes, which correspond to two paper roll holders inside the carton shell, and the two paper roll holders inside the carton are used to clamp the two ends of the paper roll.

[0007] Furthermore, the mounting hole is also equipped with a locking structure to hold the end of the connecting post in place and prevent it from rotating.

[0008] Furthermore, the cross-sectional shape of the limiting hole is T-shaped; wherein the elongated concave hole in the middle of the T-shaped limiting hole corresponds to the cylindrical part of the paper roll inserted into the paper roll holder; the short concave holes on both sides of the elongated concave hole in the T-shaped limiting hole correspond to the wing structures on both sides of the paper roll holder.

[0009] Furthermore, the mounting hole is located on a detachable mounting block within the limiting hole; wherein, on the inner side of two short recesses opposite the wing structure of the paper roll holder within the limiting hole, a through hole is provided that connects to the outside, the width of which is greater than the width of the short recesses within the limiting hole; after connecting with the short recesses, the through hole continues to extend a certain length into the limiting hole; the mounting block is embedded in the through hole and extends into the area where the through hole overlaps with the limiting hole; the mounting hole on the mounting block is located within the area of ​​the limiting hole.

[0010] Furthermore, a detachable mounting plate is fixedly provided at one end of the through hole away from the limiting hole; a second spring is provided between the mounting plate and the mounting block.

[0011] Furthermore, it also includes a clamping component, which is fixedly installed above the base and is used to clamp the outer shell of the carton placed on the base.

[0012] Furthermore, the clamping component includes a clamping seat and a clamping plate; the clamping seat is fixedly disposed above the base and located on the side of the carton shell above the base; the clamping plate is rotatably connected to the clamping seat.

[0013] Furthermore, the clamping seat is also provided with a support block for supporting the clamping plate. The support block is located on the side away from the carton shell in the rotating connection part between the clamping seat and the clamping plate.

[0014] Furthermore, an elastic layer is fixedly provided at the end of the pressing plate. The elastic layer protrudes from the pressing plate and is located below the pressing plate, facing the outer shell of the carton.

[0015] The beneficial effects of this utility model are as follows: By setting a base with limiting holes, the paper roll holder can be embedded in the limiting holes, and then the outer shell of the carton can be placed on the base, making it convenient for a single person to complete the installation of the outer shell of the carton and the paper roll holder. By setting a through hole in the limiting hole to prevent the installation block from being installed, and in conjunction with the mounting plate and the second spring, the paper roll holder with a larger clamping part can also be smoothly inserted into the limiting hole to complete the installation. By providing a snap-fit ​​structure at the bottom of the mounting hole that engages with the connecting post, rotation of the connecting post is prevented, facilitating the threaded connection between the connecting post and the screws passing through the carton shell.

Detailed Implementation

[0018] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0019] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0020] Example 1: like Figures 1-5As shown, an installation structure for a paper roll holder 21 includes a base 1 for supporting a cardboard box shell 2; the upper surface of the base 1 is flat, used to support the flat inner surface of the cardboard box shell 2; a limiting hole 11 for inserting the paper roll holder 21 is provided on the base 1, and the limiting hole 11 is also located on the upper surface of the base 1; the overall shape of the limiting hole 11 corresponds to the shape of the paper roll holder 21, and in this example, the limiting hole 11 is a T-shaped concave hole; mounting holes 12 for inserting a connecting post 23 and a first spring 25 are provided on both sides of the limiting hole 11. It should be noted that the connecting post 23 is inserted into the limiting hole 11 first, and then the first spring 25 is inserted, with the first spring 25 sleeved on the connecting post 23; a limiting hole is provided at one end of the connecting post 23. The limiting head 24 of the first spring 25 and the outer surface of the connecting post 23 are smooth to avoid interfering with the elastic deformation of the first spring 25. The other end of the connecting post 23 is provided with a threaded hole for threaded connection with the screw passing through the carton shell 2. When the paper roll holder 21 is placed into the limiting hole 11, the wing structure 22 extending laterally on both sides of the paper roll holder 21 abuts against the mounting hole 12. The wing structure 22 is used to connect with the carton shell 2. The connecting post 23 passes through the first spring 25 and the wing structure 22 on the paper roll holder 21 and is fixedly connected to the carton shell 2. After the connection is completed, the paper roll holder 21 is turned, and the paper roll holder 21 can overcome the elastic force of the first spring 25 and tilt outward to both sides. At this time, it is convenient to put the paper roll between the two paper roll holders 21.

[0021] The base 1 has two limiting holes 11, which correspond to two paper roll holders 21 inside the carton shell 2. The two paper roll holders 21 inside the carton are used to clamp the two ends of the paper roll, thus making it easier to install the two paper roll holders 21 without changing the position of the carton shell 2. The installation is completed by repeating the operation on one limiting hole 11. It should be noted that in some other embodiments, the base 1 may only have one limiting hole 11. In this case, the carton shell 2 needs to be removed, its position reversed, and the installation repeated twice to complete the installation of the two paper roll holders 21 on the carton shell 2. The cross-sectional shape of the limiting hole 11 is T-shaped. The concave structure in the middle of the T-shaped limiting hole 11 corresponds to the part of the paper roll holder 21 into which the paper roll is inserted. The short concave parts on both sides of the central concave hole in the T-shaped limiting hole 11 correspond to the wing structures 22 on both sides of the paper roll holder 21.

[0022] The mounting hole 12 is located on the detachable mounting block 13 within the limiting hole 11. Two short recesses within the limiting hole 11, opposite the wing structure 22 of the paper roll holder 21, have through holes 14 connecting to the outside. The width of the through hole 14 is greater than the width of the short recesses in the limiting hole 11. After connecting with the short recesses, the through hole 14 extends a certain length into the limiting hole 11, allowing a portion of the mounting block 13 embedded in the through hole 14 to extend into the area of ​​the limiting hole 11, while the other portion remains within the through hole 14. The mounting hole 12 on the mounting block 13 is located within the area of ​​the limiting hole 11. When replacement is needed, the mounting block 13 can be removed from the side of the through hole 14 away from the limiting hole 11. Furthermore, replacing the mounting block 13 with different sizes allows for adaptation to different paper roll holders 21. In this example, to prevent the mounting block 13 from coming out of the through hole 14, a detachable mounting plate 15 is also fixedly installed at the end of the through hole 14 away from the limiting hole 11. A second spring 16 is provided between the mounting plate 15 and the mounting block 13. Due to the action of the second spring 16, the mounting block 13 has the ability to retract into the through hole 14 and reset, so that the paper roll holder 21 with a larger paper roll clamping part can also be inserted into the limiting hole 11. The larger paper roll clamping part can increase the contact area with the end of the paper roll and better clamp the paper roll.

[0023] It should be noted that the mounting hole 12 on the mounting block 13 does not penetrate the mounting block 13. The bottom of the mounting hole 12 is also provided with a protruding "I"-shaped structure, which is used to correspond with the "I"-shaped recess on the limiting head 24 of the connecting column 23, so as to prevent it from rotating freely in the mounting hole 12, thereby making it easier to tighten the screw and complete the fixed connection between the connecting column 23 and the carton shell 2.

[0024] It also includes a clamping component 3, which is fixedly disposed above the base 1. The clamping component 3 is used to clamp the outer shell 2 of the carton placed on the base 1. In this example, the clamping component 3 includes a clamping seat 31 and a clamping plate 32. The clamping seat 31 is fixedly disposed above the base 1, located on the side of the carton shell above the base 1. The clamping plate 32 is rotatably connected to the clamping seat 31. The clamping plate 32 presses the carton shell onto the base 1 by its own weight. The clamping seat 31 is also provided with a support block 33 for supporting the clamping plate 32. The support block 33 is located on the side away from the carton shell in the rotatable connection between the clamping seat 31 and the clamping plate 32. When the clamping plate 32 does not need to press the carton shell, it can be flipped up and rotated to the side away from the carton shell, and abut against the support block 33 to complete the support placement. An elastic layer 34 is also fixedly provided at the end of the clamping plate 32. The elastic layer 34 protrudes from the clamping plate 32 and is located below the clamping plate 32, facing the outer shell 2 of the carton, to prevent damage to the outer shell 2 of the carton when the clamping plate 32 is flipped down; the elastic layer 34 is a rubber pad that is fixed in place. It should be noted that the carton shell itself is also subject to gravity, thus pressing down on the base 1. In addition, when tightening the screws on the paper roll holder 21, no large horizontal offset force is generated, so only a small pressure is needed to achieve the desired effect. Therefore, a reverse clamping structure is adopted, which is simple in structure, easy to operate, and meets the requirements.

[0025] During implementation, by setting a base 1 with a limiting hole 11, the paper roll holder 21 can be embedded into the limiting hole 11, and then the carton shell 2 can be placed on the base 1, making it convenient for a single person to complete the installation of the carton shell 2 and the paper roll holder 21; by setting a through hole 14 in the limiting hole 11 to prevent the mounting block 13 from being installed, in conjunction with the mounting plate 15 and the second spring 16, the paper roll holder 21 with a larger clamping part can also be smoothly inserted into the limiting hole 11 to complete the installation; by setting a snap-fit ​​structure 17 at the bottom of the mounting hole 12 to engage with the connecting post 23, the rotation of the connecting post 23 is prevented, making it convenient to complete the threaded connection between the connecting post 23 and the screw passing through the carton shell 2.

Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
