[0003] In existing technology, material rolls are fixed with bolts during installation. However, in order to make the position of the material roll more stable, multiple bolts are usually set. This means that multiple bolts need to be removed or installed when disassembling and assembling the material roll, making disassembly inconvenient. Utility Model Content
[0004] The main purpose of this utility model is to provide a stop device and a material roll fixing device having the same, so as to solve the problem of inconvenient assembly and disassembly of material rolls in related technologies.
[0005] To achieve the above objectives, according to one aspect of the present invention, a stopping device is provided, comprising: a mounting shell, wherein a clearance through hole is provided in the middle of the mounting shell; an operating structure, the operating structure including a first operating member and a second operating member, both the first operating member and the second operating member being adjustablely disposed on the mounting shell and located on the outer periphery of the clearance through hole, the operating structure having an initial state and an operating state; a reset member, a first end of the reset member being connected to the first operating member, a second end of the reset member being connected to the second operating member, the reset member driving the first operating member and the second operating member to keep the operating structure in the initial state; and a clamping member, the clamping member being movably disposed on the mounting shell, the clamping member being able to pass through the mounting shell and extend into the clearance through hole; wherein, when the operating structure is in the initial state, both the first operating member and the second operating member abut against the clamping member to make the clamping member extend out of the mounting shell, and when the operating structure is in the operating state, both the first operating member and the second operating member clearance the clamping member to make the clamping member retract into the mounting shell.
[0006] Furthermore, the first operating element includes an operating plate, which is rotatably mounted on the mounting housing and can abut against and engage with the clamping element.
[0007] Furthermore, the rotation axis of the operating plate is set parallel to the axis of the clearance through hole. The operating plate is an annular plate, and a driving surface is provided on the inner wall of the annular plate. The driving surface is driven to cooperate with the clamping component. In the circumferential direction of the annular plate, the distance between the driving surface and the axis of the annular plate first increases and then decreases.
[0008] Furthermore, the mounting housing is provided with a mounting hole, the opening of which communicates with the clearance through hole, the depth direction of which extends along the radial direction of the clearance through hole, and the clamping member is movably disposed within the mounting hole.
[0009] Furthermore, the clamping element includes a clamping pin, which is movably disposed within the mounting hole. When the operating structure is in its initial state, a portion of the clamping pin extends into the clearance through hole.
[0010] Furthermore, an annular mounting groove is provided inside the mounting housing, and the first operating member is rotatably disposed in the annular mounting groove. The mounting hole connects the annular mounting groove and the clearance through hole.
[0011] Furthermore, the first operating component also includes a pressing plate, which is disposed on the outer periphery of the operating plate. The mounting shell is provided with an operating opening that communicates with the annular mounting groove, and the pressing plate is movably disposed within the operating opening.
[0012] Furthermore, the mounting housing includes a first housing and a second housing connected to the first housing.

[0015] The stop device, utilizing the technical solution of this utility model, includes a mounting shell, an operating structure, a reset component, and a clamping component. A clearance through-hole allows the mounting shell to be mounted onto the mounting shaft. In the initial state, both the first and second operating components abut against the clamping component, allowing the clamping component to extend from the mounting shell into the clearance through-hole and abut against the mounting shaft, thus fixing the mounting shell to the shaft. The mounting shell then presses against the axial end face of the material roll, securing the material roll. In the operating state, both the first and second operating components abut against the clamping component, allowing the clamping component to move from the clearance through-hole into the mounting shell, disengaging from the mounting shaft. This allows the mounting shell to be removed from the shaft, and the material roll to be disassembled. The reset component drives the first and second operating components, maintaining the operating structure in its initial state, ensuring the clamping component abuts against the mounting shaft, thus securing the mounting shell, and consequently, securing the stop device. Therefore, the technical solution of this application effectively solves the problem of inconvenient assembly and disassembly of material rolls in related technologies. Attached Figure Description

[0028] like Figure 1 As shown, the stopping device of this embodiment includes: a mounting shell 10, an operating structure 20, a reset member 30, and a clamping member 40. A clearance through hole 11 is provided in the middle of the mounting shell 10. The operating structure 20 includes a first operating member 21 and a second operating member 22. Both the first operating member 21 and the second operating member 22 are adjustablely disposed on the mounting shell 10 and located on the outer periphery of the clearance through hole 11. The operating structure 20 has an initial state and an operating state. The first end of the reset member 30 is connected to the first operating member 21, and the second end of the reset member 30 is connected to the second operating member 22. The reset member 30 drives the first operating member 21 and the second operating member 22 to keep the operating structure 20 in the initial state. The clamping member 40 is movably disposed on the mounting shell 10 and can pass through the mounting shell 10 and extend into the clearance through hole 11. When the operating structure 20 is in the initial state, the first operating member 21 and the second operating member 22 both abut against the clamping member 40 so that the clamping member 40 extends out of the mounting shell 10. When the operating structure 20 is in the operating state, the first operating member 21 and the second operating member 22 both avoid the clamping member 40 so that the clamping member 40 can retract into the mounting shell 10.
[0029] Applying the technical solution of this embodiment, the stop device includes a mounting shell 10, an operating structure 20, a reset member 30, and a clamping member 40. A clearance through-hole 11 is provided, allowing the mounting shell 10 to be mounted onto the mounting shaft 100. When the operating structure 20 is in its initial state, both the first operating member 21 and the second operating member 22 can abut against the clamping member 40, allowing the clamping member 40 to extend out of the mounting shell 10 and enter the clearance through-hole 11, abutting against the mounting shaft 100. This fixes the mounting shell 10 onto the mounting shaft 100, enabling the mounting shell 10 to press against the axial end face of the material roll, thus securing the material roll. When the operating structure 20 is in its operating state, both the first operating member 21 and the second operating member 22 can abut against the clamping member 40, allowing the clamping member 40 to move from the clearance through-hole 11 into the mounting shell 10. This disengages the clamping member 40 from the mounting shaft 100, allowing the mounting shell 10 to be removed from the mounting shaft 100, and thus the material roll to be disassembled. The reset member 30 drives the first operating member 21 and the second operating member 22, enabling the operating structure 20 to remain in its initial state. This allows the clamping member 40 to abut against the mounting shaft 100, thus fixing the mounting shell 10, i.e., fixing the stop device. Therefore, the technical solution of this embodiment effectively solves the problem of inconvenient assembly and disassembly of material coils in related technologies.
[0030] like Figure 2 , Figure 3 as well as Figure 5As shown, in this embodiment, the first operating member 21 includes an operating plate 2101, which is rotatably mounted on the mounting housing 10. The operating plate 2101 can abut against the clamping member 40. By rotating the operating plate 2101, the operating structure 20 can switch between an initial state and an operating state. When the operating plate 2101 is rotated to the initial state, the operating plate 2101 can press the clamping member 40 toward the clearance through hole 11. When the operating plate 2101 is rotated to the operating state, the operating plate 2101 can disengage from the clamping member 40, and the clamping member 40 can move from the clearance through hole 11 into the mounting housing 10, thereby allowing the mounting housing 10 to be detached from the mounting shaft 100.
[0031] like Figure 2 and Figure 4 As shown, in this embodiment, the rotation axis of the operating plate 2101 is parallel to the axis of the clearance through hole 11. The operating plate 2101 is an annular plate 211, and a driving surface 2111 is provided on the inner wall of the annular plate 211. The driving surface 2111 drives and cooperates with the clamping member 40. In the circumferential direction of the annular plate 211, the distance between the driving surface 2111 and the axis of the annular plate 211 first increases and then decreases. The annular plate 211 is provided to facilitate the rotation of the operating plate 2101. When the operating structure 20 switches from the initial state to the operating state, the driving surface 2111 can separate from the clamping member 40, and the clamping member 40 can then move from the clearance through hole 11 into the mounting shell 10. When the operating structure 20 switches from the operating state to the initial state, the driving surface 2111 can abut against the clamping member 40, and the clamping member 40 can then move from the mounting shell 10 into the clearance through hole 11.
[0032] Specifically, when the operating structure 20 switches from the initial state to the operating state, the driving surface 2111 can separate from the clamping member 40 and the mounting shell 10 can move along the axial direction of the mounting shaft 100. At this time, the mounting shaft 100 can abut against the clamping member 40, so that the clamping member 40 can move from the clearance through hole 11 into the mounting shell 10, which facilitates the removal of the mounting shell 10 from the mounting shaft 100.
[0033] The second operating component 22 includes an operating ring 222. An arc-shaped surface 2221 is provided on the inner wall of the operating ring 222. In the direction from the first end 22211 to the second end 22212 of the arc-shaped surface, the distance between the arc-shaped surface 2221 and the axis of the operating ring 222 first increases and then decreases.
[0034] The direction from the first end 22211 to the second end 22212 of the arc-shaped surface is set parallel to the circumferential direction of the operating ring 222.
[0035] In the direction from the first end 21111 to the second end 21112 of the driving surface, the distance between the driving surface 2111 and the axis of the annular plate 211 first increases and then decreases. The direction from the first end 21111 to the second end 21112 of the driving surface is parallel to the circumferential direction of the operating ring 222.
[0036] The direction from the first end 22211 to the second end 22212 of the arc surface is opposite to the direction from the first end 21111 to the second end 21112 of the driving surface.
[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the mounting shell 10 is provided with a mounting hole 12, the opening of which communicates with the clearance through hole 11. The depth direction of the mounting hole 12 extends along the radial direction of the clearance through hole 11. The clamping member 40 is movably disposed within the mounting hole 12. The clamping member 40 can move within the mounting hole 12, thereby moving from the clearance through hole 11 into the mounting shell 10, or vice versa.
[0038] It should be noted that there are multiple clamping members 40, multiple mounting holes 12, and multiple driving surfaces 2111 are set to correspond one-to-one with multiple clamping members 40.
[0039] like Figures 2 to 4 As shown, in this embodiment, the clamping member 40 includes a clamping pin 41. When the operating structure 20 is in the initial state, a portion of the clamping pin 41 extends into the clearance through hole 11. The clamping pin 41 is provided to facilitate the installation of the stop device onto the mounting shaft 100, or to allow the stop device to be removed from the mounting shaft 100.
[0040] like Figure 2 and Figure 5 As shown, in this embodiment, an annular mounting groove 13 is provided inside the mounting housing 10. The first operating member 21 is rotatably disposed within the annular mounting groove 13. The mounting hole 12 connects the annular mounting groove 13 and the clearance through hole 11. The annular mounting groove 13 can limit the movement of the first operating member 21, making the rotation of the first operating member 21 smoother. The mounting hole 12 connects the annular mounting groove 13 and the clearance through hole 11, so that when the first operating member 21 rotates, it can drive the clamping member 40 to move, or avoid the clamping member 40.
[0041] like Figure 1 and Figure 2As shown, in this embodiment, the first operating member 21 further includes a pressing plate 212, which is disposed on the outer periphery of the operating plate 2101. The mounting shell 10 is provided with an operating opening 14 communicating with the annular mounting groove 13, and the pressing plate 212 is movably disposed within the operating opening 14. Pressing the pressing plate 212 can drive the operating plate 2101 to rotate. The provision of the operating opening 14 facilitates the change of position of the pressing plate 212.
[0042] like Figure 1 and Figure 2 As shown, in this embodiment, the mounting housing 10 includes a first housing 15 and a second housing 16 connected to the first housing 15. A first operating member 21 and a second operating member 22 are rotatably disposed between the first housing 15 and the second housing 16, with the first operating member 21 and the second operating member 22 rotating in opposite directions. The first housing 15 and the second housing 16 can axially limit the first operating member 21 and the second operating member 22, allowing the first operating member 21 and the second operating member 22 to rotate between the first housing 15 and the second housing 16. The opposite rotation directions of the first operating member 21 and the second operating member 22 facilitate the operation of the operating structure 20, enabling the operating structure 20 to switch between an initial state and an operating state.
[0043] The reset member 30 includes a spring that surrounds the outer periphery of the first operating member 21 and the second operating member 22 and is located between the first housing 15 and the second housing 16.
[0044] Mounting holes 12 are provided on the side of the first housing 15 facing the second housing 16. Mounting holes 12 are also provided on the side of the second housing 16 facing the first housing 15.
[0045] The annular mounting groove 13 includes a first groove and a second groove. The first groove is located on the side of the first housing 15 facing the second housing 16, and the second groove is located on the side of the second housing 16 facing the first housing 15. The mounting hole 12 is connected to the first groove.
[0046] like Figure 2 and Figure 3 As shown, in this embodiment, the mounting housing 10 further includes a connector 17. The first operating member 21 has a first strip-shaped hole 213, and the second operating member 22 has a second strip-shaped hole 221. The connector 17 passes through the first strip-shaped hole 213 and the second strip-shaped hole 221 and connects to the first housing 15 and the second housing 16. The connector 17 passes through the first strip-shaped hole 213 and the second strip-shaped hole 221, thereby connecting the first housing 15 and the second housing 16.
[0047] The first housing 15 is provided with a first threaded hole, the second housing 16 is provided with a second threaded hole, and the connecting member 17 is a connecting screw, which is threadedly engaged with the first threaded hole and the second threaded hole.
[0048] The connector 17, the first threaded hole and the second threaded hole are all included in multiples, and the multiple connectors 17, the multiple first threaded holes and the multiple second threaded holes are set one-to-one.
[0049] In the circumferential direction of the first housing 15, a first threaded hole is provided between any two adjacent mounting holes 12.
[0050] like Figure 6 As shown, the coil fixing device of this embodiment includes a mounting shaft 100 and a stop device. The mounting shaft 100 passes through the clearance through hole 11 of the mounting shell 10 of the stop device, and the stop device is the stop device described above. The operating structure 20 of the stop device can switch between an initial state and an operating state, thereby allowing the clamping member 40 to move from the clearance through hole 11 into the mounting shell 10, or the clamping member 40 to move from the mounting shell 10 into the clearance through hole 11. This enables the mounting shell 10 to be installed on the mounting shaft 100, or the mounting shell 10 to be removed from the mounting shaft 100, making the assembly and disassembly of the coil more convenient. The coil fixing device with the stop device described above also has the advantages mentioned above.
[0051] It should be noted that the stop device also allows the fixed position of the stop device on the mounting shaft 100 to be selected according to the actual thickness of the material roll.
[0052] The material roll can be label paper, tape, or other objects.
[0053] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.
[0054] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0055] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
