Description

[Technical Field]

[0001] The present invention relates to a fixing device, and more particularly to a paper roll fixing device. [Background technology]

[0002] Patent Document 1 discloses an improvement to a roll-type toilet paper holder. The device has an inverted L-shaped base that is fixed to a wall surface, a cantilever, and at least one or two sets of pressure plates. A C-shaped columnar fitting groove is installed in the base, and the cantilever is fixed to the base with a bolt, with an axis holder attached to the tip, and a roll of toilet paper is attached to the axis holder. The pressing plate has a pressing portion formed at the lower front edge for pressing down the toilet paper, and the other end of the pressing plate has a fitting shaft portion which is inserted into the fitting groove of the base. Furthermore, two plug-like members seal both ends of the fitting groove to prevent the retainer plate from falling off.

[0003] However, the above-mentioned devices have significant drawbacks in practical use. When a user pulls out toilet paper, the force of the pull tends to deflect the pressure plate upward, causing it to hit the base and produce an unpleasant impact noise. Such noise not only impairs the user's experience of use, but can also be a significant nuisance in quiet environments. As described above, the structure of the device has problems in terms of stability and quiet design, and there is room for improvement. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Republic of China Utility Model No. M483056 Summary of the Invention [Problem to be solved by the invention]

[0005] The prior art has drawbacks in terms of stability and quiet design. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, this invention relates to a roll paper fixing device that uses an elastic cushioning member between the layer plate and the pressure plate, making it less likely for the pressure plate to come into contact with the layer plate, preventing noise and making it easier to cut off the roll paper.

[0007] The roll paper fixing device of the present invention comprises a base, a pressure plate, a hinge shaft, a silencer, a cantilever, and an elastic buffer member. The base has a fixed plate and a layer plate extending perpendicularly from one end of the fixed plate, and a first hinge portion is installed inside the fixed plate and the layer plate; the presser plate has a pressing portion and a second hinge portion located away from the pressing portion, the second hinge portion having a curved, wound shape; The hinge shaft passes through the first hinge portion and the second hinge portion, and thus the presser plate can rotate relative to the base; the silencer is made of a soft material, the silencer is installed to cover the periphery of the hinge shaft, and the silencer is located between the hinge shaft and the second hinge part; One end of the cantilever is fixed to the fixed plate, and the other end is disposed extending below the pressing portion, The elastic buffer member is placed over the periphery of the silencer, with one end of the elastic buffer member abutting against the layer plate and the other end abutting against the pressing plate, which makes it difficult for the pressing portion to come into contact with the layer plate.

[0008] As a result, the elastic cushioning member contacts the layer plate and the pressure plate, cushioning the bouncing motion of the pressure plate when the user pulls out the roll of paper, effectively preventing the noise caused by the pressure plate colliding with the layer plate, and also making it easier to separate the roll of paper, further improving comfort during use and product durability.

[Figure 4] 1 is a schematic diagram showing the roll paper fixing device of the present invention in use, showing the cantilever inserted into the roll paper; FIG. [Figure 5] 1 is a schematic diagram showing the roll paper fixing device of the present invention in use, illustrating the operation of pulling out the roll paper and showing that the pressure plate is unlikely to come into contact with the shelf plate. [Figure 6] 10 is a schematic view showing the appearance of a second embodiment of the roll paper fixing device according to the present invention; FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] To more clearly illustrate the central idea presented in the above disclosure of the present invention, specific embodiments are presented below.

[0011] As shown in FIGS. 1 to 5, the first embodiment of the roll paper holder 100 according to the present invention comprises a base 10, a pressure plate 20, a hinge shaft 30, a silencer 40, a cantilever 50, and an elastic buffer member 60. The roll paper fixing device 100 of the first embodiment belongs to a single holder and is used to attach one roll paper 1. The roll paper 1 is toilet paper.

[0012] The base 10 is made of a metal material and has a fixed plate 11 and a layer plate 12 extending perpendicularly from one end of the fixed plate 11 . An article can be placed on the layer plate 12, and a first hinge portion 13 is provided on the inside of the fixed plate 11 and the layer plate 12. The fixed plate 11 and the layer plate 12 are integrally formed by bending. The first hinge portion 13 has a first hinge ear 131 and a second hinge ear 132 spaced apart. The first hinge ear 131 and the second hinge ear 132 are formed by bending integrally from the fixed plate 11, and each of the first hinge ear 131 and the second hinge ear 132 has one through-hole 133. The fixing plate 11 has a locking slot 111, which allows the base 10 to be fixed to a wall surface using a screw member.

[0013] The pressing plate 20 has a pressing portion 21 and a second hinge portion 22 located at a position separated from the pressing portion 21, and the second hinge portion 22 has a curved, wound shape. A radial slit 221 is provided at the middle position of the second hinge portion 22, and the radial slit 221 faces the pressing portion 21, and an alignment end portion 2211 is provided.

[0014] The hinge shaft 30 passes through the through holes 133 of the first hinge ear 131 and the second hinge ear 132, thereby pivotally connecting the pressure plate 20 to the base 10, and thus the pressure plate 20 can rotate relative to the base 10. The hinge shaft 30 has a stopper portion 31 at one end and a threaded portion 32 at the other end. The hinge shaft 30 passes through the first hinge ear 131 and the second hinge ear 132 , so that the stopper portion 31 is located outside the first hinge ear 131 , and the screw portion 32 is screwed into the screw fixing member 33 .

[0015] The silencer 40 is made of a soft material and is installed to cover the periphery of the hinge shaft 30, and the silencer 40 is located between the hinge shaft 30 and the second hinge part 22. The silencer 40 reduces frictional contact when the retaining plate 20 rotates, effectively suppressing abnormal sounds from the hinge and reducing noise during use.

[0016] The cantilever 50 has a first end 51 and a second end 52 . The first end 51 is fixed to the fixed plate 11, and the second end 52 is disposed extending below the pressing portion . The cantilever 50 is adapted to allow a roll of paper 1 to be placed thereon. The cantilever 50 is fixed to the fixed plate 11 by welding.

[0017] The elastic buffer member 60 is placed over the periphery of the silencer 40, with one end of the elastic buffer member 60 abutting against the layer plate 12 and the other end abutting against the pressing plate 20, thereby making it difficult for the pressing portion 21 to come into contact with the layer plate 12. In the embodiment of the present invention, the elastic buffer member 60 is a torsion spring, and includes a sleeve portion 61 and a first support arm 62 and a second support arm 63 extending from the sleeve portion 61 . The first support arm 62 and the second support arm 63 have bent portions 621 and 631 at their ends, respectively. The sleeve portion 61 is installed over the periphery of the silencer 40, and the first support arm 62 and the second support arm 63 protrude from the radial slit 221, with the bent portion 621 of the first support arm 62 abutting against the layer plate 12 and the bent portion 631 of the second support arm 63 abutting against the pressure plate 20, respectively. As shown in FIG. 3, the second support arm 63 is fixed to the alignment end 2211, and the bent portions 621, 631 increase the contact force, making it difficult for the presser plate 20 to come into contact with the layer plate 12. Moreover, the user can easily cut the roll paper 1, and the bent portions 621, 631 of the elastic buffer member 60 make it less likely that the presser plate 20 and the layer plate 12 will be damaged.

[0018] As also shown in FIGS. 2 and 5, when the user pulls out the paper roll 1, a portion of the paper roll 1 is cut by the pressing portion 21 of the pressure plate 20. At this time, the force of the user pulling out causes the pressure plate 20 to rebound upward, but because the first support arm 62 of the elastic cushioning member 60 abuts against the layer plate 12 and the second support arm 63 abuts against the pressure plate 20, the return movement of the pressure plate 20 is buffered and the pressing part 21 of the pressure plate 20 is less likely to collide with the layer plate 12, thus preventing the generation of collision noise, maintaining a quiet environment and making it easier to cut the roll paper 1.

[0019] Furthermore, the silencer 40 of the present invention not only reduces the generation of abnormal noise when the retaining plate 20 pivots relative to the base 10, but also provides better positioning of the hinge shaft 30 and the elastic buffer member 60 during assembly, thereby improving the convenience of the assembly work.

[0020] As shown in FIG. 6, the second embodiment of the paper roll holder 100a according to the present invention differs from the first embodiment in that the paper roll holder 100a of the second embodiment is a double type, and can accommodate two paper rolls 1.

[0021] To sum up, the present invention has the following advantages: 1. In this device, the elastic buffer member 60 is placed between the pressure plate 20 and the layer plate 12 to provide a buffer when the pressure plate 20 swings as the user pulls out the roll of paper 1. This makes it difficult for the pressing part 21 to come into contact with the layer plate 12, avoiding the generation of impact noise and making it easier to cut out the roll of paper 1 while maintaining a quiet environment. 2. The silencer 40 of this invention reduces frictional contact when the retaining plate 20 rotates, effectively suppressing abnormal hinge noise. Moreover, the silencer 40 serves as a reference for the installation position of the hinge shaft 30 and the elastic buffer member 60, thereby improving the overall assembly accuracy.

[0022] The above-mentioned embodiments are used only to explain the present invention, and do not limit the scope of the present invention. Any changes or modifications that do not contradict the spirit of the invention are intended to be included within the scope of the utility model claims of the invention. [Explanation of symbols]
