Description

Technical Field

[0001] This utility model relates to the field of manual punching tools, and more particularly to a punching machine. Background Technology

[0002] A hole punch is a tool used to punch binding holes in media (e.g., paper, photographs, etc.). Existing hole punches generally achieve punching by pressing down on the punching mechanism with a handle. For example, Chinese utility model patent ZL201920848750.2 (authorization announcement number CN210148291U) discloses a press-type document punching device, including a base with a support on the base. A pressing block is hinged to the support and can rotate around a horizontal axis. A handle is located at the end away from the hinge. A vertically movable punch with its head facing downwards is located below the pressing block. A sleeve that cooperates with the punch is provided on the support. A pressure plate is located directly below the pressing block, with one end of the pressure plate hinged to the support and rotatable around a horizontal axis. The pressure plate and the pressing block are connected by a spring. A return spring is provided on the sleeve to bring the punch to its highest position. For example, Chinese utility model patent ZL202121836879.5 (authorization announcement number CN215749593U) discloses a punching device for binding accounting documents, relating to the field of financial office supplies technology. The device features a machine body fixedly connected to the rear top of a workbench, with symmetrically distributed hot riveting handles slidably connected to the machine body. A riveting head assembly is located on one side of the bottom of the machine body, and a drill assembly is located to the right of the riveting head assembly. A drilling assembly is also provided, and the drilling assembly is threadedly connected to the front top of the workbench. Storage assemblies are fixedly connected to both sides of the workbench. However, when the medium is large, punching cannot be completed in one go. In this case, multiple repeated punching operations are required along the length of the medium. If the holes cut in the previous and subsequent punching operations are not aligned, it will affect the final punching effect on the medium. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a punching machine that can align pre-cut holes on a medium and achieve good punching effect, in contrast to the existing technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: a drilling machine, comprising a base and a drilling structure disposed on the top surface of the base, characterized in that a positioning element for positioning a medium is movably disposed on the top surface of the base, the positioning element having at least two states:

[0005] 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.

[0006] In the second state, the aforementioned positioning component is hidden beneath the top surface of the aforementioned base.

[0007] 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).

[0008] Furthermore, the positioning element is vertically arranged and includes a base and a positioning post. The base is gate-shaped, and the positioning post is integrally protruding from the top surface of the base and connected to the hole on the medium. The base and the mounting channel are slidably fitted into the mounting channel with upper and lower guides.

[0009] The base is provided with a mounting chamber, and the mounting channel extends through the top wall of the mounting chamber, with a limit strip horizontally positioned at the lower end of the mounting channel.

[0010] In the first state described above, the positioning component rises to its highest point, with the outer top surface of the base flush with or lower than the top surface of the base, and the positioning post fully exposed. In the second state described above, the positioning component descends to its lowest point, with the inner top surface of the base abutting against the limiting strip, and the positioning post completely hidden within the mounting hole. This allows the positioning component to smoothly move up and down along the mounting hole, and it can be stably positioned in the second state by the limiting strip.

[0011] Furthermore, limiting protrusions are respectively provided on the outer surfaces of the two sidewall ends of the base. In the first state described above, each limiting protrusion abuts against the lower edge of the mounting channel. The limiting protrusions on both sides can prevent the positioning component from coming out of the mounting channel during the upward movement.

[0012] Furthermore, the installation chamber is provided with a top support that can slide horizontally back and forth relative to the positioning member, so that the positioning member can move up and down along the installation channel.

[0013] Furthermore, in the second state, the aforementioned supporting member is located beside the aforementioned positioning member. When the supporting member is moved horizontally below the positioning member, it can support the positioning member upwards, thereby positioning the positioning member in the aforementioned first state. In the aforementioned first state, the aforementioned supporting member is moved horizontally and disengaged from the positioning member, and the positioning member falls along the aforementioned mounting hole under its own gravity. The supporting member enables the supporting drive for the positioning member to rise along the mounting hole, and when the positioning member rises to its highest height, it can be positioned to stably maintain the positioning member in the aforementioned first state.

[0014] Furthermore, the supporting member includes a horizontally extending sliding plate and a top block protruding from one side of the upper surface of the sliding plate and used to support the positioning member. The top surface of the top block is a plane, while the first side surface is an inclined surface sloping outward from top to bottom.

[0015] In the second state described above, the top holding member is moved to the first side of the top block and abuts against the positioning member. As the top holding member continues to move, the positioning member moves upward along the first side until it reaches the top surface of the top block. The positioning member is in the first state described above.

[0016] The sliding plate enables the top member to move horizontally, while the top block enables the top member to lift and support the positioning member. Specifically, the first side of the top block enables the positioning member to rise smoothly, while the top surface of the top block limits the positioning member in its highest state, so that the positioning member is stable in the first state mentioned above.

[0017] Furthermore, a lever for actuating the top support member is provided at the other end of the upper surface of the sliding plate, and a guide groove extending along the translational direction of the top support member is vertically provided on the top wall of the mounting chamber. The lever is tightly fitted into the guide groove and can slide back and forth along the guide groove. When the lever slides to one end of the guide groove, the positioning member is in the first state, and when the lever slides to the other end of the guide groove, the positioning member is in the second state.

[0018] By moving the toggle block, the top holding member can be moved horizontally, thereby switching the positioning member between the two states. Through the cooperation of the toggle block and the guide groove, it can be ensured that the positioning member can switch smoothly between the two states and can be kept firmly in the two states, so as to ensure the reliability of positioning the punched hole on the medium.

[0019] Furthermore, the lever is a vertically extending column, and the lever, top block, and sliding plate are a single piece.

[0020] This allows for a simple structure and robust internal structure of the top support, which helps extend its service life.

[0021] Furthermore, the bottom surface of the installation chamber includes a horizontally extending support plane, on which the aforementioned top support is placed flat, and the bottom surface of the top support is guided and engaged with the support plane along the sliding direction of the top support.

[0022] This not only ensures the stable installation of the top support but also guarantees its smooth movement, thus improving the user experience.

[0023] Furthermore, an installation window is provided through the top wall of the installation chamber. The drilling structure includes a housing and a drilling mechanism detachably mounted on the housing. The base plate of the drilling mechanism extends horizontally and covers the installation window, and the installation channel is opened at the base plate corresponding to the installation window. Compared with the method of directly opening the installation channel on the base, this method is beneficial to improving the ease of assembling and disassembling the positioning and supporting components.

[0024] Compared with the prior art, the advantages of this utility model are as follows: A positioning element is provided, and 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 punched in the first and second punching operations and guaranteeing the drilling effect on the medium. Furthermore, 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 affecting the flat placement of the medium on the top surface of the base during the first drilling operation, and also preventing damage to the protruding positioning element from impacts.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They 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 utility model 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.

[0038] like Figures 1-11 As shown, a punching machine includes a base 1 and a punching structure 2 disposed on the top surface of the base 1. Further, a positioning element 3 for positioning a medium is movably disposed on the top surface of the base 1, the positioning element 3 having at least two states:

[0039] In the first state, the positioning element 3 protrudes from the top surface of the base 1 to accommodate the punched holes in the medium, such as... Figure 1 As shown;

[0040] In the second state, the aforementioned positioning component 3 is hidden beneath the top surface of the aforementioned base 1, as shown below. Figure 4 As shown.

[0041] As can be seen from the above, the punching machine of this utility model is equipped with a positioning component 3. In the first state, the positioning component 3 protrudes from the top surface of the base 1, so that the punched holes on the medium can be fitted onto the positioning component 3. The positioning component 3 can achieve the positioning of the punched holes on the medium, so that the holes punched in the medium before and after are aligned, ensuring the punching effect of the medium. In addition, in the second state, the positioning component 3 is hidden under the top surface of the base 1. In this way, the positioning component 3 can be stored when not in use. On the one hand, it avoids the positioning component 3 from affecting the flat placement of the medium on the top surface of the base 1 during the first punching. On the other hand, the positioning component 3 protruding from the top surface of the base 1 is prone to damage. The medium in this utility model can be paper, cloth, photographs, etc. In this embodiment, it is specifically paper, and the following description uses paper as an example.

[0042] Furthermore, there are various specific arrangements for the positioning element 3. Preferably, the top of the base 1 has a vertically extending mounting hole 12, and the positioning element 3 can be vertically raised and lowered within the mounting hole 12. This allows the positioning element 3 to protrude from the top surface of the base 1 or be hidden below the top surface of the base 1. In this way, the positioning element 3 can be switched between the two states through a simple structural design (setting a mounting hole 12 on the base 1) and a simple movement of the positioning element 3 (vertical raising and lowering).

[0043] Furthermore, the aforementioned positioning element 3 is vertically arranged and includes a base 31 and a positioning post 32. Specifically, as shown... Figure 10 and Figure 11 As shown, the base 31 is door-shaped, and the positioning post 32 is integrally protruding from the top surface of the base 31 and connected to the hole on the paper. The base 31 and the mounting channel 12 are slidably fitted into the mounting channel 12 with vertical guides. The base 1 has a mounting chamber 11, and the mounting channel 12 passes through the top wall of the mounting chamber 11. A limiting strip 121 is horizontally spaced at the lower end of the mounting channel 12. In the first state, the positioning member 3 rises to its highest position, the outer top surface of the base 31 is flush with the top surface of the base 1, and the positioning post 32 is fully exposed. In the second state, the positioning member 3 descends to its lowest position, the inner top surface of the base 31 abuts against the limiting strip 121, and the positioning post 32 is completely hidden in the mounting channel 12. This allows the positioning member 3 to move smoothly up and down along the mounting channel 12, and it can be stably limited in the second state by the limiting strip 121. Preferably, as Figure 9 and Figure 11 As shown, limiting protrusions 311 are respectively provided on the outer surfaces of the two sidewall ends of the base 31. In the first state, each limiting protrusion 311 abuts against the lower edge of the mounting channel 12. The limiting protrusions 311 on both sides can prevent the positioning member 3 from falling out of the mounting channel 12 during the rising process.

[0044] Furthermore, the mounting chamber 11 is equipped with a top-holding member 4 that can slide horizontally back and forth relative to the positioning member 3. In the second state, the top-holding member 4 is located beside the positioning member 3. When the top-holding member 4 is moved to below the positioning member 3, it can hold the positioning member 3 upwards, so that the positioning member 3 is in the first state and is positioned. In the first state, the top-holding member 4 moves horizontally and disengages from the positioning member 3, and the positioning member 3 falls along the mounting channel 12 under its own weight. The top-holding member 4 provides a top-holding drive for the positioning member 3 to rise along the mounting channel 12. When the positioning member 3 rises to its highest height, it can be positioned so that the positioning member 3 is stably maintained in the first state.

[0045] In this embodiment, specifically, as follows: Figure 3 and Figure 6 As shown, the aforementioned supporting member 4 includes a horizontally extending sliding plate 41 and a top block 42 protruding from one end of the upper surface of the sliding plate 41 for supporting the aforementioned positioning member 3. The top surface of the top block 42 is a plane, while the first side surface 421 (specifically the rear side surface in this embodiment) is an inclined surface sloping outward from top to bottom. In the second state described above, the supporting member 4 is translated until the first side surface 421 of the top block 42 abuts against the positioning member 3. As the supporting member 4 continues to translate, the positioning member 3 moves upward along the first side surface 421 until it reaches the top surface of the top block 42, at which point the positioning member 3 is in the first state described above. The sliding plate 41 enables the translation of the supporting member 4, while the top block 42 enables the supporting member 4 to support and lift the positioning member 3. Specifically, the first side surface 421 of the top block 42 enables the smooth lifting of the positioning member 3, while the top surface of the top block 42 enables the positioning member 3 to be limited in its highest state, thus stabilizing the positioning member 3 in the first state described above.

[0046] Furthermore, a lever 43 for actuating the top support 4 is provided at the other end of the upper surface of the sliding plate 41. A guide groove 111 extending vertically along the translational direction of the top support 4 is provided on the top wall of the mounting chamber 11. The lever 43 is tightly fitted into the guide groove 111 and can slide back and forth along the guide groove 111. When the lever 43 slides to one end of the guide groove 111, the positioning member 3 is in the first state (e.g., ...). Figure 1 As shown), when the toggle block 43 slides to the other end of the guide groove 111, the positioning member 3 is in the second state (as shown). Figure 4 (As shown). By moving the toggle block 43, the top holding member 4 is moved horizontally, thereby switching the positioning member 3 between the two states. Through the cooperation of the toggle block 43 and the guide groove 111, on the one hand, the positioning member 3 can be smoothly switched between the two states, and on the other hand, the positioning member 3 can be stably maintained in the two states respectively, so as to ensure the reliability of positioning the punched holes on the paper.

[0047] Furthermore, preferably, the aforementioned lever 43 is a vertically extending column, and the lever 43, the top block 42, and the sliding plate 41 are a single piece; in this embodiment, the top support 4 is a single piece. This makes the structure of the top support 4 simple and its internal structure robust, which is beneficial for extending the service life of the top support 4.

[0048] In this embodiment, specifically, the top holding member 4 extends in the front-back direction and can move back and forth along its own length direction, the push block 43 is disposed at the front end of the sliding plate 41, the top block 42 is located at the rear end of the sliding plate 41, and the positioning member is disposed on the rear side of the top holding member 4.

[0049] Furthermore, preferably, the bottom surface of the mounting chamber 11 includes a horizontally extending support plane 51, the top support 4 is placed flat on the support plane 51, and the bottom surface of the top support 4 is guided and engaged with the support plane 51 along the sliding direction of the top support 4. This not only ensures the stable installation of the top support 4 but also guarantees its smooth translation, which is beneficial to improving the user experience. Specifically, as... Figure 6 As shown, a support plate 5 is horizontally arranged below the aforementioned top support 4, and the upper surface of the support plate 5 forms the aforementioned support plane 51.

[0050] Furthermore, in this embodiment, as Figure 1 and Figure 8 As shown, an installation window 112 is provided through the top wall of the installation chamber 11. The drilling structure 2 includes a housing 21, a drilling mechanism 22 detachably mounted on the housing 21, and a handle 23. Drilling is achieved by rotating the handle 23 to press down the drilling mechanism 22. Furthermore, the base plate 221 of the drilling mechanism 22 extends horizontally and covers the installation window 112, and the installation channel 12 is opened at the base plate 221 corresponding to the installation window 112. Compared with the method where the installation channel 12 is directly opened on the base 1, this improves the ease of assembling and disassembling the positioning member 3 and the top support member 4.
