Abstract
Description
A binding machine Technical Field
[0001] This invention relates to the field of coil binding devices, and more particularly to a binding machine. Background Technology
[0002] In traditional binding methods, the coil is first threaded through the binding holes of various media (such as paper, photographs, etc.), and then the coil is manually pressed into a closed shape. However, this binding method is not only inefficient, but also has the problem that the coil may not be completely pressed into a closed shape, causing the media to come off the coil during use.
[0003] To address this, Chinese utility model patent ZL202121180841.7 (authorization announcement number CN217347268U) discloses a binding machine, including a support frame. The support frame is equipped with a guide block for fixing a coil, a clamping assembly for holding the coil, and a pressing assembly for pressing down the coil. The clamping assembly is located above the guide block. The pressing assembly includes a pressure rod, a snap plate, and a connecting plate. The pressure rod passes through the coil along its entire axial direction. One end of the pressure rod is fixed to the connecting plate, and the other end is close to the snap plate. The snap plate is movably fixed to the connecting plate, and the connecting plate is movably fixed to the support frame. Compared with traditional binding methods, the above patent improves the convenience and efficiency of binding; however, this binding machine can only be used to bind coils of a fixed size.
[0004] Furthermore, to bind the media, holes must first be punched in the media. After punching, the media are bound together using a coil. To achieve both punching and binding functions, both a binding machine and a binding machine are required. However, configuring both binding machines simultaneously is not only costly but also cumbersome to operate, affecting the user experience.
[0005] To this end, Chinese utility model patent with patent number ZL99204863.X (authorization announcement number CN2362670Y) discloses a paper punching and binding merging device, including a housing, a punching device, an elastic load pressure plate, a coil pressing device, and an adjustable cam brake. The punching device is equipped with a knife holder and a plurality of punching knives, each of which is equipped with a sliding baffle, which can be selected to punch with the knife holder. The elastic load pressure plate is pivotally mounted on the front support shaft of the housing, which assists in the threading of stacked paper through the spiral coil. The end of the second rotating shaft of the coil pressing device is fixed with a second rocker handle, and a transmission gear is provided to mesh with the second tooth row of the L-shaped pressure plate to press the open spiral coil into a closed shape. The adjustable cam brake is in contact with the protrusion of the L-shaped pressure plate. It is evident that although the aforementioned patent integrates the punching and binding functions into the same device, the structure is complex. Furthermore, simply combining the punching and binding functions results in two independent functions that are still relatively cumbersome to operate. For example, the user needs to operate the first crank when punching and the second crank when pressing. Summary of the Invention
[0006] The first technical problem to be solved by the present invention is to provide a binding machine that can be used to bind coils of various sizes, in contrast to the prior art.
[0007] The second technical problem to be solved by the present invention is to provide a binding machine that integrates binding and punching functions in contrast to the prior art.
[0008] The third technical problem to be solved by the present invention is to provide a binding machine that can limit the handle and avoid dry printing, in contrast to the prior art.
[0009] The fourth technical problem to be solved by the present invention is to provide a binding machine that can lock the handle to stop it from moving, in contrast to the prior art.
[0010] The fifth technical problem to be solved by the present invention is to provide a binding machine that can align the punched holes on the medium and achieve a good punching effect, in contrast to the prior art.
[0011] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is as follows: a binding machine, including a base, wherein the top surface of the base is respectively provided with:
[0012] First pressed component;
[0013] The second pressing member is disposed opposite to the first pressing member, and in the initial state, there is an initial distance between them;
[0014] An adjustment mechanism is used to drive the second pressing member to adjust the initial distance between the second pressing member and the first pressing member, and to match the initial distance with the size of the coil to be pressed.
[0015] A pressing drive is used to drive a first pressing member to move toward a second pressing member in the initial state to press the coils between the two.
[0016] An adjusting mechanism is used to adjust the initial distance between the first and second pressing components, matching this initial distance to the size of the coil to be pressed. A pressing drive is then used to drive the first pressing component toward the second pressing component, thus pressing the coil between them. Therefore, this invention can press various coil sizes (6.4mm to 16mm), enabling the binding of products using coils of different sizes, such as notebooks, calendars, and photo albums.
[0017] Furthermore, both the first and second pressing components are elongated plates, and they are vertically aligned and face each other along the horizontal direction, allowing the coil to be inserted into the gap between them along its length. By designing the specific shapes and arrangements of the first and second pressing components, they can better cooperate in pressing the coil.
[0018] Furthermore, both the first pressing component and the second pressing component are elongated strips and are arranged parallel to each other along the horizontal direction. The aforementioned adjustment mechanism includes:
[0019] An adjusting plate is set horizontally and fixed to one side of the second pressing component.
[0020] The adjustment hole is elongated and is provided on the adjustment plate. Its length direction intersects with the length direction of the second pressing member and is inclined to one side from the length direction of the second pressing member.
[0021] The movable shaft is limited to move back and forth in a direction parallel to the length direction of the second pressing member, and is vertically connected in the adjustment hole, moving back and forth along the length direction of the adjustment hole to drive the adjustment plate. Thus, when the movable shaft moves, it can drive the adjustment plate to move along the distance between the first and second pressing members, thereby driving the first pressing member to move towards or away from the second pressing member, changing the initial distance between them. Furthermore, when pressing the coil, because the movable shaft is limited along the distance between the first and second pressing members, displacement of the second pressing member due to the movement of the movable shaft is prevented.
[0022] Furthermore, the adjustment mechanism also includes a guide groove formed on the base, which extends in a direction parallel to the length direction of the second pressing member. One end of the movable shaft is fitted into the guide groove and can move back and forth along the guide groove. The movable shaft is confined in the guide groove by the cooperation between the movable shaft and the guide groove, and can move back and forth in a direction parallel to the length direction of the second pressing member.
[0023] Furthermore, the adjustment mechanism also includes a movable plate that extends horizontally, and the aforementioned movable shaft is mounted on the movable plate, which facilitates the stable setting of the movable shaft.
[0024] Furthermore, a hollow boss protrudes from one side of the top surface of the base. The adjusting plate, the moving plate, and the moving shaft are all housed within the cavity of this boss. Guide grooves are respectively formed on the inner top and inner bottom surfaces of the boss, and the upper and lower ends of the moving shaft are respectively embedded in the corresponding guide grooves and can move back and forth along the corresponding guide grooves.
[0025] Furthermore, a mounting opening extending along the length of the second pressing member is provided on one side of the aforementioned boss. The second pressing member is a plate vertically arranged in the horizontal direction and can cover the mounting opening. The corresponding surface of the adjusting plate and the second pressing member is fixed along the length direction. A long strip-shaped guide opening is provided on the other side of the aforementioned boss. The length direction of the guide opening is parallel to the length direction of the second pressing member. A first lever protrudes from one end of the moving plate. The first lever is embedded in the guide opening and can move back and forth along the guide opening. This makes the overall structure of the adjusting mechanism more compact and allows the moving shaft to move more smoothly, thereby ensuring the smooth movement of the first pressing member driven by the adjusting plate, and thus ensuring the reliability of the initial distance adjustment between the first and second pressing members. In addition, by providing the first lever, it is easy to move the moving plate, thereby facilitating the adjustment of the initial distance.
[0026] Furthermore, when the first lever is located at one end of the guide port, the moving shaft is located at one end of the adjustment hole, and the second pressing member covers the mounting port, with the distance between the second pressing member and the first pressing member being at its maximum. When the first lever is located at the other end of the guide port, the moving shaft is located at the other end of the adjustment hole, the second pressing member is located outside the mounting port, and the initial distance between the second pressing member and the first pressing member is at its minimum. This allows the first pressing member to be stabilized in its initial state and in a state with the minimum initial distance.
[0027] The technical solution adopted to further solve the second technical problem mentioned above is as follows: a drilling mechanism is also provided on the top surface of the base. The drilling mechanism includes a handle that can rotate up and down and is equipped with an elastic reset member, and a drilling structure. The handle can press down on the drilling structure to realize drilling, and can rotate up to reset under the action of the elastic reset member.
[0028] Furthermore, the first pressing component and the second pressing component are respectively disposed on the side of the drilling mechanism.
[0029] It also includes a transmission mechanism for linking the handle and the first pressing member.
[0030] In the initial state, a gap for placing a coil is formed between the first pressing member and the second pressing member. The coil to be pressed is placed into the gap, and the handle is turned so that the first pressing member moves toward the second pressing member to press the coil placed between the two.
[0031] The coil to be pressed is placed into the gap between the first and second pressing components. Turning the handle downwards causes the first pressing component to move towards the second pressing component, pressing the coil placed between them. Thus, the handle of the punching mechanism drives the punching structure to punch holes while simultaneously driving the first pressing component to achieve binding. After binding, the first pressing component can be reset by the elastic reset component of the handle, facilitating repeated binding. The integration of punching and binding functions not only makes the internal structure of the device compact and simple but also makes it easy to operate and provides a good user experience.
[0032] Furthermore, the transmission mechanism includes a cam, a transmission gear set, and a transmission rack. The cam is located at the end of the handle's connecting end and can rotate about the handle's pivot. The transmission gear set includes a first transmission gear meshing with the cam and a second transmission gear meshing with the transmission rack. The first and second transmission gears mesh. The transmission rack is connected to the first pressing member and extends along the distance between the first and second pressing members. Rotating the handle causes the transmission rack to move back and forth along its own length. Thus, rotating the handle drives the transmission gear set via the cam, which in turn drives the transmission rack, causing the first pressing member to move, thereby transmitting the handle to the first pressing member.
[0033] Furthermore, the first pressing component is a long strip-shaped plate arranged vertically along the horizontal direction. A horizontally extending sliding base plate is installed at the lower end of the first pressing component. The aforementioned transmission racks are respectively provided on both sides of the sliding base plate, and the sliding base plate can move back and forth along the length direction of each transmission rack.
[0034] The aforementioned transmission mechanism further includes a gear seat arranged parallel to the length direction of the first pressing member. The gear seat has an upper gear shaft and a lower gear shaft located below the upper gear shaft, both along their own length. The first transmission gear is mounted at both ends of the upper gear shaft, while the second transmission gear is mounted at both ends of the lower gear shaft. Two cams are spaced apart, parallel to the length direction of the first pressing member. Each cam meshes with the corresponding first transmission gear, and each transmission rack meshes with the corresponding second transmission gear. This design allows the first pressing member to move more smoothly back and forth along the distance between the first and second pressing members under the drive of the handle.
[0035] Furthermore, the bottom surface of the gear seat is flat and slides against the top surface of the sliding base plate. A rollable ball is provided at the bottom of the gear seat, with at least a portion of the ball protruding from the bottom surface of the gear seat, and the lowest point of the ball protruding below the bottom surface of the gear seat. By designing the ball to reduce friction between the bottom surface of the gear seat and the top surface of the sliding base plate, the movement of the first pressing component becomes smoother, reducing friction between parts and extending the service life of the component.
[0036] The technical solution adopted to further solve the third and fourth technical problems mentioned above is as follows: it also includes a handle and a drilling structure, wherein one end of the handle is an operating end for hand gripping and the other end is a connecting end, the connecting end is rotatably mounted on the top surface of the base via a pivot, the handle can press down on the drilling structure to achieve drilling, and it also includes a locking member movably disposed on one side of the handle for locking the handle, the locking member having a first notch.
[0037] Furthermore, the aforementioned locking element has at least two states:
[0038] In the first state, the first notch is opposite to the connecting end and allows the end of the connecting end to pass through;
[0039] In the second state, the first notch is offset from the connecting end, and the locking member can limit the end of the connecting end so that the handle cannot be rotated and the perforated structure is pressed down.
[0040] A locking element is provided, which has a first notch. In the first state, the first notch is opposite to the connecting end, allowing the end of the connecting end to pass through, thus enabling the handle to rotate normally up and down and ensuring the normal punching function of the binding machine. In the second state, the first notch is offset from the connecting end, and the locking element limits the end of the connecting end, preventing the handle from rotating and pressing down on the punching structure. This prevents the handle from pressing down on the punching structure when not in operation (i.e., not punching), thus preventing the punching structure from being accidentally driven (i.e., dry punching), improving the reliability of the device structure, and facilitating storage and transportation.
[0041] Furthermore, the locking member also includes a locking portion, and the end of the handle connection has a second notch. In the second state, the locking portion is opposite to the second notch and engages with it to stop the handle. By providing the second notch and utilizing its engagement with the locking portion on the locking member to stop the handle, not only is accidental activation of the perforated structure prevented when not in use, but the handle is also prevented from rotating, thus facilitating storage and transportation.
[0042] Furthermore, a resilient reset element is installed on the pivot of the handle. In the initial state, the handle is tilted along its length, with the connecting end located at the lower end of the handle and the operating end located at the upper end.
[0043] The aforementioned locking member is a horizontally extending, elongated plate. This plate is positioned perpendicular to the length direction of the handle and can move back and forth along its own length. The aforementioned locking portion and the aforementioned first notch are arranged side by side along the length direction of the locking member.
[0044] In the initial state, the locking member is located above the connecting end of the handle. Rotating the operating end of the handle downwards causes the connecting end to rotate upwards until the operating end is close to the top surface of the base. Moving the locking member aligns its locking portion with the connecting end of the handle, causing it to engage in the second notch of the connecting end. Simultaneously, the elastic reset member deforms, causing the connecting end to tend to rotate downwards and reset. This simplifies the structure of the locking member, facilitating locking and unlocking of the handle by operating it (i.e., moving the locking member along its length). Furthermore, when the handle is locked, the elastic reset member ensures the handle remains reliably locked.
[0045] The technical solution adopted to further solve the fifth technical problem mentioned above is as follows: it also includes a perforated structure on the top surface of the base, wherein a positioning element for positioning the medium is movably provided on the top surface of the base, and the positioning element has at least two states:
[0046] In the first state, the aforementioned positioning element protrudes from the top surface of the aforementioned base to accommodate the punched holes on the medium.
[0047] In the second state, the aforementioned positioning component is hidden beneath the top surface of the aforementioned base.
[0048] A positioning element is provided. In the first state, the positioning element protrudes from the top surface of the base. The punched holes on the medium can be fitted onto the positioning element to position the punched holes on the medium, ensuring alignment of the holes from two punching operations and guaranteeing the drilling effect. In the second state, the positioning element is hidden under the top surface of the base. This allows the positioning element to be stored away when not in use, preventing it from interfering with the flat placement of the medium on the top surface of the base during the initial drilling process, and also preventing damage to the protruding positioning element from impacts.
[0049] Furthermore, the top of the base has a vertically extending mounting hole, in which the positioning member can be vertically raised or lowered, so that the positioning member protrudes from the top surface of the base or is hidden below the top surface of the base. In this way, the positioning member can be switched between the two states through a simple structural design (setting a mounting hole in the base) and a simple movement of the positioning member (vertical raising or lowering).
[0050] Furthermore, one side of the base is provided with a row of hanging posts arranged in a straight line for hooking the coil along its length. Hooking the coil along its length onto each hanging post facilitates the insertion of the medium through the binding holes on the posts onto the coil.
[0051] Furthermore, it also includes a baffle, and the top surface of the base has an insertion hole for vertically inserting the baffle. When the baffle is inserted into the top surface of the base, it abuts against the side of the medium to position it. Using the baffle to align the medium helps ensure accurate drilling positions.
[0052] Furthermore, the baffle is elongated, with protruding posts extending along its width at both ends. The insertion holes are arranged on the top surface of the base, allowing each post to be inserted. These holes are arranged in a preset array. In this array, the post at one end of the baffle is inserted into the corresponding hole according to the working position of the medium, ensuring that the post at the other end can always be inserted into the corresponding other hole. This allows users to easily adjust the position of the baffle according to different medium sizes and perforation structures, improving the user experience.
[0053] Furthermore, the base is recessed with a storage groove for accommodating the baffle, and when the baffle is stored in the storage groove, it is hidden beneath the outer surface of the base. This prevents the baffle from being lost when not in use.
[0054] Compared with existing technologies, the advantages of this invention are as follows: This invention utilizes an adjustment mechanism to adjust the initial distance between the first and second pressing components, matching this initial distance to the size of the coil to be pressed. A pressing drive component then drives the first pressing component to move towards the second pressing component, thus pressing the coil between them. Therefore, this invention can press various coil sizes (6.4mm to 16mm), thereby enabling the binding of products using coils of different sizes, such as notebooks, calendars, and photo albums.

[0086] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0087] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and 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. Since the embodiments disclosed in this invention can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
[0088] Example 1:
[0089] As shown in Figures 1 to 9, a binding machine includes a base 6. A first pressing member 201, a second pressing member 202, an adjusting mechanism 30, and a pressing drive are respectively disposed on the top surface of the base 6. The second pressing member 202 is disposed opposite to the first pressing member 201, and initially, there is an initial gap between the second pressing member 202 and the first pressing member 201. The adjusting mechanism 30 drives the second pressing member 202 to adjust the initial gap between the second pressing member 202 and the first pressing member 201, matching the size of the initial gap to the size of the coil to be pressed. The pressing drive drives the first pressing member 201 to move towards the second pressing member 202 in the initial state to press the coil between them.
[0090] As can be seen from the above, the present invention utilizes the adjusting mechanism 30 to adjust the initial distance between the first pressing member 201 and the second pressing member 202, and makes the initial distance match the size of the coil to be pressed. The pressing drive member then drives the first pressing member 201 to move towards the second pressing member 202 to press the coil between them. Therefore, the present invention can achieve the pressing of coils of various sizes (6.4mm to 16mm), thereby enabling the binding of products using coils of different sizes, such as notebooks, calendars, and photo albums.
[0091] Preferably, both the first pressing component 201 and the second pressing component 202 are elongated plates, and they are vertically aligned facing each other in the left-right direction so that the coil can be inserted into the gap between them along its length, as shown in Figures 1 and 7. By designing the specific shapes of the first pressing component 201 and the second pressing component 202, as well as their specific arrangement, the two components can better cooperate to press the coil.
[0092] Further, as shown in Figures 4 and 5, the aforementioned adjustment mechanism 30 includes an adjustment plate 301, an adjustment hole 3011, and a moving shaft 302. The adjustment plate 301 is horizontally positioned and fixed to one side of the second pressing member 202. The adjustment hole 3011 is elongated and formed on the adjustment plate 301. The length direction of the adjustment hole 3011 intersects the length direction of the second pressing member 202 and is inclined to one side from the length direction of the second pressing member 202.
[0093] Furthermore, the aforementioned movable shaft 302 can be limited to move back and forth in a direction parallel to the length direction of the second pressing member 202, and is vertically connected in the aforementioned adjusting hole 3011, and can move back and forth along the length direction of the adjusting hole 3011 to drive the aforementioned adjusting plate 301. Thus, when the movable shaft 302 moves, it can drive the adjusting plate 301 to move along the distance between the first pressing member 201 and the second pressing member 202, thereby driving the first pressing member 201 to move towards or away from the second pressing member 202, thereby changing the initial distance between them. Furthermore, when pressing the coil, since the movable shaft 302 is limited along the distance between the first pressing member 201 and the second pressing member 202, displacement of the second pressing member 202 due to the movement of the movable shaft 302 can be avoided.
[0094] Preferably, as shown in FIG. 5, the adjustment mechanism 30 further includes a guide groove 602 formed on the base 6. The guide groove 602 extends in a direction parallel to the length direction of the second pressing member 202, and one end of the moving shaft 302 is embedded in the guide groove 602 and can move back and forth along the guide groove 602. The moving shaft 302 is limited in the guide groove 602 by the cooperation between the moving shaft 302 and the guide groove 602, and can move back and forth in a direction parallel to the length direction of the second pressing member 202. In addition, the adjustment mechanism 30 also includes a moving plate 3030, which extends horizontally and is provided on the upper or lower side of the adjustment plate 301, and the moving shaft 302 is mounted on the moving plate 3030, which is beneficial to achieve a stable setting of the moving shaft 302.
[0095] In this embodiment, specifically as shown in Figures 1, 6, and 7, a hollow boss 601 protrudes from one side of the top surface of the base 6. The adjusting plate 301, the moving plate 3030, and the moving shaft 302 are all housed within the cavity of the boss 601. Guide grooves 602 are respectively formed on the inner top and bottom surfaces of the boss 601. The upper and lower ends of the moving shaft 302 are respectively embedded in the corresponding guide grooves 602 and can move back and forth along the corresponding guide grooves 602. There are two adjusting plates 301, spaced vertically apart. The moving plate 3030 is sandwiched between the two adjusting plates 301, which facilitates the smooth movement of the moving plate 3030. Each adjusting plate 301 has an adjusting hole 3011, and the upper and lower ends of the moving shaft 302 on the moving plate 3030 pass through the adjusting holes 3011 of the corresponding adjusting plate 301.
[0096] Furthermore, one side of the aforementioned boss 601 is a vertical wall with a mounting opening 1130 extending to the left and right. The aforementioned second pressing member 202 is a vertically arranged plate that can cover the mounting opening 1130. The corresponding surfaces of each of the aforementioned adjusting plates 301 and the second pressing member 202 are fixed along the length direction. In this embodiment, preferably, each adjusting plate 301 and the second pressing member 202 are integral parts (as shown in Figure 5). The other side of the aforementioned boss 601 is provided with a long strip-shaped guide opening 603. The length direction of the guide opening 603 is parallel to the length direction of the aforementioned second pressing member 202. One end of the aforementioned moving plate 3030 is provided with a first lever 304. The first lever 304 is embedded in the aforementioned guide opening 603 and can move back and forth along the guide opening 603, as shown in Figure 2. This allows for a more compact overall structure of the adjusting mechanism 30 and a smoother movement of the moving shaft 302, ensuring the smooth movement of the first pressing member 201 driven by the adjusting plate 301, and consequently ensuring the reliability of the initial distance adjustment between the first pressing member 201 and the second pressing member 202. Furthermore, the first lever 304 facilitates the movement of the moving plate 3030, thereby enabling the adjustment of the initial distance.
[0097] Furthermore, when the first lever 304 is located at one end of the guide port 603, the moving shaft 302 is located at one end of the adjustment hole 3011, and the second pressing member 202 covers the mounting port 1130, with the distance between the second pressing member 202 and the first pressing member 201 being at its maximum. When the first lever 304 is located at the other end of the guide port 603, the moving shaft 302 is located at the other end of the adjustment hole 3011, the second pressing member 202 is located outside the mounting port 1130, and the initial distance between the second pressing member 202 and the first pressing member 201 is at its minimum, thereby stabilizing the first pressing member 201 in its initial state and at its minimum initial distance.
[0098] Furthermore, preferably, the aforementioned pressing drive is rotatably mounted on the top surface of the base 6 and is provided with an elastic reset member 220, and is linked to the first pressing member 201 via a transmission mechanism 400 (detailed in Embodiment 3). In the initial state, the coil to be pressed is placed in the gap between the first pressing member 201 and the second pressing member 202, and the pressing drive is rotated downwards. This pressing drive causes the first pressing member 201 to move towards the second pressing member 202, pressing the coil placed between the first pressing member 201 and the second pressing member 202. The elastic reset member 220 deforms, causing the pressing drive to tend to rotate upwards and return to its initial state. Thus, the rotation of the pressing drive can drive the first pressing member 201, and after pressing, the pressing drive automatically resets under the action of the elastic reset member 220, making operation convenient and improving the user experience. In this embodiment, the pressing drive is the handle 8, and the elastic reset member 220 is a torsion spring mounted on the shaft 800 of the handle 8.
[0099] Furthermore, in this embodiment, as shown in FIG8, a row of hanging posts 60 arranged in a straight line on one side of the base 6 are provided for hooking the coil along its length. Hooking one side of the coil along its length onto each hanging post 60 facilitates the insertion of the medium through the binding hole onto the coil. The medium can be paper, cloth, photographs, etc.; in this embodiment, it is specifically paper.
[0100] Furthermore, as shown in Figures 8 and 9, a baffle 70 is also included, and the top surface of the base 6 has an insertion hole 604 for vertically inserting the baffle 70. When the baffle 70 is inserted into the top surface of the base 6, it abuts against the side of the medium to position it. Using the baffle 70 to align the medium helps ensure accurate drilling. Specifically, the baffle 70 is elongated, with insertion posts 701 extending along its width protruding from both ends. The insertion holes 604 are arranged on the top surface of the base 6 for inserting the insertion posts 701, and these holes 604 are arranged in a preset array 140. In the array 140, the insertion post 701 at one end of the baffle 70 is inserted into the corresponding socket 604 according to the working position of the medium (i.e. the position where the hole needs to be placed). The insertion post 701 at the other end can always be inserted into the other corresponding socket 604, so that the user can adjust the position of the baffle 70 according to different medium sizes, different hole structures, etc., so that the medium is placed in the correct position and the user experience is improved.
[0101] Furthermore, as shown in Figure 8, the base 6 is recessed with a storage groove 130 for receiving the baffle 70. When the baffle 70 is stored in the storage groove 130, it is hidden beneath the outer surface of the base 6, thus preventing the baffle 70 from being lost when not in use. Further, a storage box 80 for collecting debris generated during drilling is slidably installed on the bottom of the base 6, and this storage box 80 can extend horizontally outward from the base 6, as shown in Figure 8. Collecting the debris in the storage box 80 prevents it from scattering and also facilitates emptying the collected debris.
[0102] Example 2:
[0103] As shown in Figures 10-18, unlike Embodiment 1, in this embodiment, a drilling mechanism 100 is also provided on the top surface of the base 6. The drilling mechanism 100 includes the handle 8, which can rotate up and down and is provided with the elastic reset member 220, and a drilling structure 10. The handle 8 can press down on the drilling structure 10 to make a hole, and can rotate up to reset under the action of the elastic reset member 220.
[0104] Furthermore, the first pressing member 201 and the second pressing member 202 are respectively disposed on the side of the drilling mechanism 100. The first pressing member 201 and the second pressing member 202 are each elongated and are arranged opposite each other in the left-right direction. A transmission mechanism 400 for linking the handle 8 with the first pressing member 201 is also included. In the initial state, a gap for placing a coil is formed between the first pressing member 201 and the second pressing member 202. The coil to be pressed is placed into this gap, and the handle 8 is rotated downwards to move the first pressing member 201 toward the second pressing member 202, thus pressing the coil placed between them. In this embodiment, specifically, the elastic reset member 220 is a torsion spring mounted on the rotating shaft 800 of the handle 8.
[0105] In this embodiment, specifically as shown in Figures 12, 14, and 15-18, the transmission mechanism 400 includes a cam 401, a transmission gear set 402, and a transmission rack 4031. The cam 401 is located at the end of the connecting end 82 (the other end is the operating end 81) of the handle 8 and can rotate about the pivot 800 of the handle 8 (as shown in Figures 11 and 12). The transmission gear set 402 includes a first transmission gear 4021 meshing with the cam 401 and a second transmission gear 4022 meshing with the transmission rack 4031, wherein the first transmission gear 4021 meshes with the second transmission gear 4022. The transmission rack 4031 is connected to the first pressing member 201 and extends along the distance between the first pressing member 201 and the second pressing member 202. Rotating the handle 8 can drive the transmission rack 4031 to move back and forth along its own length. In this way, the handle 8 rotates, which drives the transmission gear set 402 via the cam 401, and the transmission gear set 402 drives the transmission rack 4031 to move the first pressing member 201, thereby transmitting the handle 8 to the first pressing member 201. In this embodiment, the top surface of the base 6 is covered with a mounting cover 63, and the connecting end of the handle 8 and the transmission mechanism 400 are both housed in the mounting cover 63. Furthermore, the first pressing member 201 is located on the front side of the mounting cover 63, and the perforated structure 10 is located on the rear side of the mounting cover 63.
[0106] Further, as shown in Figures 17 and 18, a sliding base plate 403 extending horizontally in the front-rear direction is installed at the lower end of the first pressing member 201. The sliding base plate 403 has transmission racks 4031 respectively installed on its left and right sides, and the sliding base plate 403 can move back and forth along the length direction of each transmission rack 4031. The transmission mechanism 400 also includes a gear seat 404 arranged in a direction parallel to the length direction of the first pressing member 201 (specifically, the left-right direction in this embodiment). The gear seat 404 has an upper gear shaft 4041 and a lower gear shaft 4042 located below the upper gear shaft 4041, both along their own length direction. The upper gear shaft 4041 has a first transmission gear 4021 installed at both ends, while the lower gear shaft 4042 has a second transmission gear 4022 installed at both ends. The aforementioned cams 401 are two in number and spaced apart in the left-right direction. Each cam 401 meshes with the first transmission gear 4021 on the corresponding side, while each transmission rack 4031 meshes with the second transmission gear 4022 on the corresponding side. This design allows the first pressing member 201 to move back and forth more smoothly along the distance between the first pressing member 201 and the second pressing member 202 under the drive of the handle 8.
[0107] Furthermore, as shown in Figures 17 and 18, the bottom surface of the gear seat 404 is flat and slides against the top surface of the sliding base plate 403. A rollable ball bearing 405 is provided at the bottom of the gear seat 404, with at least a portion of the ball bearing 405 exposed on the bottom surface of the gear seat 404, and the lowest point of the ball bearing 405 protruding below the bottom surface of the gear seat 404. By designing the ball bearing 405 to reduce friction between the bottom surface of the gear seat 404 and the top surface of the sliding base plate 403, the movement of the first pressing member 201 becomes smoother, reducing friction between parts and extending the service life of the component. In this embodiment, the bottom surface of the gear seat 404 is square, and the ball bearing 405 is provided at each of the four corners of the bottom surface, as shown in Figure 11.
[0108] Example 3:
[0109] As shown in Figures 19-26, unlike Embodiment 2, this embodiment further includes a locking member 04 movably disposed on one side of the handle 8 for locking the handle 8. The locking member 04 has a first notch 041. Furthermore, the locking member 04 has at least two states:
[0110] In the first state, the first notch 041 is opposite to the connecting end 82 of the handle 8, and the end of the connecting end 82 can pass through, as shown in Figure 23;
[0111] In the second state, the first notch 041 and the connecting end 82 are offset from each other, and the locking member 04 can limit the end of the connecting end 82 so that the handle 8 cannot rotate and press down the perforated structure 10, as shown in Figure 24.
[0112] As can be seen from the above, the binding machine of the present invention is equipped with a locking member 04, which has a first notch 041. In the first state, the first notch 041 of the locking member 04 is opposite to the connecting end 82 of the handle 8, and the end of the connecting end 82 can pass through, thereby allowing the handle 8 to rotate normally up and down, ensuring the normal punching function of the binding machine (as shown in Figure 23). In the second state, the first notch 041 of the locking member 04 is offset from the connecting end 82, and the locking member 04 can limit the end of the connecting end 82, so that the handle 8 cannot rotate and press down on the punching structure 10, avoiding the handle 8 pressing down on the punching structure 10 in the non-working state (i.e., the non-punching state), that is, avoiding the punching structure 10 being mistakenly driven (i.e., dry punching), improving the reliability of the device structure, and facilitating storage and transportation.
[0113] Furthermore, the locking member 04 is also provided with a locking part 042, and the end of the connecting end 82 of the handle 8 is provided with a second notch 2211. In the second state, the locking part 042 is opposite to the second notch 2211 and engages with the second notch 2211 to stop the handle 8 (as shown in FIG24). By providing the second notch 2211, the handle 8 is stopped by cooperating with the locking part 042 on the locking member 04. In this way, in the non-working state, not only can the punching structure 10 be prevented from being accidentally driven (i.e., dry punching) but the handle 8 can also be prevented from rotating, thus making it more convenient to store and transport. Preferably, in the second state, the operating end 81 of the handle 8 is adjacent to the top surface of the base 6 (i.e., the handle 8 is in a nearly horizontal state), as shown in FIG22, which can further ensure the reliability of locking the handle 8, and placing the handle 8 horizontally is beneficial for the storage and transport of the binding machine.
[0114] In this embodiment, as shown in FIG20, an elastic reset member 220 is installed on the rotating shaft 800 of the handle 8. In the initial state, the handle 8 is inclined along its own length direction, and the connecting end 82 is located at the lower end of the handle 8 while the operating end 81 is located at the upper end of the handle 8. The locking member 04 is a horizontally extending strip-shaped plate. The plate is arranged in a direction perpendicular to the length direction of the handle 8 (left-right direction in this embodiment) and can move back and forth along its own length direction. The locking part 042 and the first notch 041 are arranged side by side along the length direction of the locking member 04. In the initial state, the locking member 04 is located on the connecting end 82 of the handle 8. Rotating the operating end 81 of the handle 8 downwards causes the connecting end 82 of the handle 8 to rotate upwards until the operating end 81 is adjacent to the top surface of the base 6. Moving the locking member 04 causes its locking part 042 to align with the connecting end 82 of the handle 8, and the locking part 042 engages in the second notch 2211 of the connecting end 82. Simultaneously, the elastic reset member 220 deforms, causing the connecting end 82 to tend to rotate downwards and reset. This simplifies the structure of the locking member 04, facilitating locking and unlocking of the handle 8 by operating the locking member 04 (i.e., moving the locking member 04 along its length). Furthermore, when the handle 8 is locked, the elastic reset member 220 ensures that the handle 8 remains reliably locked and automatically returns to its initial state upon unlocking, facilitating drilling operations. In this embodiment, the elastic reset member 220 is specifically a torsion spring.
[0115] Furthermore, as shown in Figure 21, a bracket 05 is vertically arranged on the top surface of the base 6 along the length of the locking member 04. Each end of the bracket 05 has a mounting opening 051, through which the two ends of the locking member 04 are respectively connected. The locking member 04 can move back and forth relative to each mounting opening 051 along its own length. This allows for both the installation of the locking member 04 and its movement along its own length, enabling switching between unlocked and locked states. Furthermore, the locking member 04 has a protruding actuating block 043 for moving it back and forth along its own length. The actuating block 043 facilitates the user's movement of the locking member 04 along its own length, thus enabling control over the switching between unlocked and locked states. In this embodiment, specifically, the bracket 05 includes support plates 052 located opposite each other on the left and right sides. Each support plate 052 extends in the front-back direction, and the upper end of each support plate 052 is provided with the above-mentioned mounting port 051, as shown in FIG21.
[0116] In this embodiment, as shown in Figures 19 and 20, a mounting cover 63 is provided on the top surface of the base 6 to form a mounting cavity (not shown). The connecting end 82 of the handle 8 and the locking member 04 are both accommodated in the mounting cavity. A guide hole 631 extending along the length direction of the locking member 04 is provided on the mounting cover 63. The actuating block 043 is embedded in the guide hole 631 and can move back and forth along the length direction of the guide hole 631. When the actuating block 043 is located at one end of the guide hole 631, the locking member 04 is in the first state; when the actuating block 043 is located at the other end of the guide hole 631, the locking member 04 is in the second state. The toggle block 043 is exposed to the mounting cover 63 through the guide hole 631, which makes it convenient for the user to operate the toggle block 043. The sliding of the toggle block 043 in the guide hole 631 helps to ensure the smooth movement of the locking member 04 along its own length direction, thereby helping to ensure the reliability of the unlocking and locking state switching control.
[0117] Furthermore, as shown in Figures 25 and 26, the aforementioned actuating block 043 includes a base plate 0431 extending along the length of the locking member 04 and a block 0432 protruding from one side of the base plate 0431. The block 0432 is fitted into a guide hole 631. A mounting post 0433 protrudes from the other side of the base plate 0431. The mounting post 0433 is tensioned and connected to a mounting hole (not shown) on the locking member 04, so that the actuating block 043 is mounted on the upper surface of the locking member 04. This allows the actuating block 043 to be securely mounted on the locking member 04 and facilitates the assembly and disassembly of the actuating block 043 from the locking member 04.
[0118] Example 4:
[0119] As shown in Figures 27-31, unlike Embodiment 2, in this embodiment, a positioning member 5 for positioning the medium is movably provided on the top surface of the base 6. This positioning member 5 has at least two states: in the first state, the positioning member 5 protrudes from the top surface of the base 6 to accommodate punched holes in the medium; in the second state, the positioning member 5 is hidden below the top surface of the base 6. Thus, by providing the positioning member 5, and in the first state where the positioning member 5 protrudes from the top surface of the base 6, the punched holes in the medium can be fitted onto the positioning member 5, achieving the positioning of the punched holes in the medium, ensuring alignment of the holes punched in the first and second punching operations, and guaranteeing the drilling effect on the medium. Furthermore, in the second state, the positioning member 5 is hidden below the top surface of the base 6, allowing it to be stored when not in use. This avoids the positioning member 5 affecting the flat placement of the medium on the top surface of the base during the first drilling, and also prevents the positioning member 5 from being easily damaged due to its protrusion on the top surface of the base 6.
[0120] Furthermore, as shown in Figure 31, a vertical mounting hole 4200 is provided at the top of the base 6. The positioning member 5 can be vertically and flexibly disposed in the mounting hole 4200, so that the positioning member 5 protrudes from the top surface of the base 6 (as shown in Figure 1) or is hidden below the top surface of the base 6 (as shown in Figure 29). This allows the positioning member 5 to perform its positioning function, and also allows it to be hidden and stored when not in use. By hiding the positioning member 5, it is possible to avoid the positioning member 5 affecting the flat placement of the medium on the top surface of the base 6 during the initial drilling, and also to prevent the positioning member 5 from being easily damaged due to protrusion on the top surface of the base 6.
[0121] In this embodiment, specifically as shown in FIG29, the positioning member 5 is vertically arranged and includes a base 51 and a positioning post 52. The base 51 is gate-shaped, and the positioning post 52 is integrally protruding from the top surface of the base 51 and connected to a hole on the medium. The base 51 is slidably fitted into the mounting channel 4200 with vertical guides. The base 6 has a mounting chamber 60, and the mounting channel 4200 passes through the top wall of the mounting chamber 60, with a limit strip 424 horizontally spaced at the lower end of the mounting channel 4200. In the positioning state (first state), when the positioning member 5 is raised to its highest position, the outer top surface of the base 51 is flush with or lower than the top surface of the base 6, and the positioning post 52 is fully exposed. In the unpositioned state (second state), the positioning member 5 descends to its lowest point, the inner top surface of the base 51 abuts against the limiting strip 424, and the positioning post 52 is completely hidden in the mounting channel 4200. This allows the positioning member 5 to smoothly move up and down along the mounting channel 4200, and it can be stably positioned in the second state by the limiting strip 424.
[0122] Furthermore, the mounting chamber 60 is provided with a supporting member 7 that can slide horizontally back and forth relative to the positioning member 5, allowing the positioning member 5 to move up and down along the mounting channel 4200, as shown in FIG28. In the second state, the supporting member 7 is located beside the positioning member 5. When the supporting member 7 is moved to below the positioning member 5, it can support the positioning member 5 upwards, so that the positioning member 5 is in the first state and is positioned. In the first state, the supporting member 7 moves horizontally and disengages from the positioning member 5, and the positioning member 5 falls along the mounting channel 4200 under its own gravity. The supporting member 7 provides a supporting drive for the positioning member 5 to rise along the mounting channel 4200. When the positioning member 5 rises to its highest height, it can be positioned so that the positioning member 5 is stably maintained in the first state.
[0123] Further, specifically, as shown in Figure 28, the aforementioned supporting member 7 includes a horizontally extending sliding plate 71 and a top block 73 protruding from one side of the upper surface of the sliding plate 71 for supporting the aforementioned positioning member 5. The top surface of the top block 73 is flat, while the first side surface 731 is an inclined surface sloping outward from top to bottom. In the aforementioned second state, the aforementioned supporting member 7 is translated until the first side surface 731 of the top block 73 abuts against the positioning member 5, and as the supporting member 7 continues to translate, the positioning member 5 moves upward along the first side surface 731 until it reaches the top surface of the top block 73, at which point the positioning member 5 is in the aforementioned first state. The other end of the upper surface of the aforementioned sliding plate 71 is provided with a second lever 72 for actuating the aforementioned supporting member 7, and a guide groove 61 extending vertically along the translational direction of the aforementioned supporting member 7 is provided on the top wall of the aforementioned mounting chamber 60. The aforementioned second lever 72 is tightly fitted into the guide groove 61 and can slide back and forth along the guide groove 61. Furthermore, when the second lever 72 slides to one end of the guide groove 61, the positioning member 5 is in the first state, and when the second lever 72 slides to the other end of the guide groove 61, the positioning member 5 is in the second state.
