Description

Technical Field

[0001] This utility model belongs to the technical field of binding equipment, and specifically relates to a large-capacity staple box for a stapler. Background Technology

[0002] A stapler is a tool used for binding paper, cardboard, etc., and is widely used in offices, factories, and homes. While current staplers on the market are simple in structure and easy to use, most have small staple bin capacities. When a large number of binding jobs are needed, the staples in the bin are consumed quickly, requiring frequent opening of the top cover to add staples, which is time-consuming and laborious.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0004] The purpose of this invention is to provide a high-capacity staple box for electric staplers.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A high-capacity staple box for a stapler, the staple box having an inner cavity for holding staples, a staple outlet at the bottom of the staple box, and two retaining plates on both sides of the bottom of the staple box in the width direction to prevent staples from falling out, the two retaining plates being rotatably connected to the bottom of the staple box, and two oppositely arranged hanging rods at both ends of the inner side of the two retaining plates in the length direction, and a tension spring for tensioning the hanging rods between the two retaining plates, the two hanging rods extending into the tension spring from both ends and located inside the tension spring.

[0007] Furthermore, a first hook is rotatably provided on both sides of the nail box along its length, and both first hooks are located near the nail outlet.

[0008] Furthermore, the nail box is provided with a rotating seat and a rotating plate rotatably connected to the rotating seat on both sides corresponding to the first hook. The rotating seat and the rotating plate are rotatably connected at the middle. The rotating plate is arranged vertically, and the first hook is fixed at the lower end of the rotating plate.

[0009] Furthermore, the middle part of the rotating seat and the rotating plate are rotatably connected by a pin, and a locking spring is fixed between the upper end of the rotating plate and the nail box.

[0010] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0011] This utility model features a simple and reliable large-capacity staple box structure. Before use, a large number of staples are stacked vertically inside the staple box. The latch at the staple outlet is then opened and installed on the stapler, allowing the staples to fall out for the stapler to use. Staples can be added only when all the staples in the staple box are used up. This eliminates the need to frequently add staples to the staple box during staple making, effectively improving work efficiency. After the staple box is removed from the stapler, the latch at the staple outlet is automatically tightened by the tension spring, preventing staples from falling out.

[0012] Furthermore, two first hooks are rotatably provided on the side of the staple box to facilitate securing the staple box to the stapler and improve stability during use. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] like Figures 1 to 5As shown, a large-capacity stapler box for a stapler is provided. The stapler box 1 has an inner cavity for holding staples 10. The bottom of the stapler box 1 has a staple outlet 11. On both sides of the bottom of the stapler box 1 in the width direction, there are retaining plates 12 to prevent the staples 10 from falling out. The two retaining plates 12 are rotatably connected to the bottom of the stapler box 1. At both ends of the inner length direction of the two retaining plates 12, there are opposing hanging rods 13. Preferably, in this embodiment, the hanging rods 13 are integrally formed on the corresponding retaining plates 12. A space is also provided between the two retaining plates 12 for... The tension springs 14 tensioned by the hanging rods 13 are respectively set at both ends of the length direction of the clamping plate 12 and corresponding to the positions of the hanging rods 13. The two hanging rods 13 extend into the tension springs 14 from both ends and are located inside the tension springs 14, so that the tension springs 14 tension the two hanging rods 13 on the two clamping plates 12 under their own elastic force. The tension of the two hanging rods 13 causes the clamping plates 12 to block the nail outlet 11 of the nail box 1. At this time, the distance between the two clamping plates 12 is less than the width of the nail outlet 11, preventing the book staples 10 from falling off.

[0041] The large-capacity staple box of this utility model has a simple and reliable structure. Before use, a large number of staples 10 are stacked vertically in the inner cavity of the staple box 1. The retaining plate 12 at the staple outlet 11 is opened and installed on the stapler. The staples 10 can then fall from the staple outlet 11 for use by the stapler. When all the staples 10 in the staple box 1 are used up, more staples can be added. During binding, there is no need to frequently add staples 10 to the staple box 1, which can effectively improve work efficiency. After the staple box 1 is removed from the stapler, the retaining plate 12 at the staple outlet 11 is automatically tightened by the tension spring 14 to prevent the staples 10 from falling out.

[0042] Furthermore, two first hooks 15 are rotatably provided on both sides of the nail box 1 along its length. Both first hooks 15 are located near the nail outlet 11. The nail box 1 is provided with a rotating seat 16 and a rotating plate 17 rotatably connected to the rotating seat 16 on both sides corresponding to the first hooks 15. The middle of the rotating seat 16 and the rotating plate 17 are rotatably connected by a pin. The rotating plate 17 is arranged vertically. The first hooks 15 are fixed at the lower end of the rotating plate 17. A locking spring 18 is fixed between the upper end of the rotating plate 17 and the nail box 1. This arrangement makes the lower end of the rotating plate 17 form the first hook 15, and the upper end of the rotating plate 17 form a pressing end for pressing by hand. When the pressing end is pressed towards the nail box 1, the locking spring 18 is compressed, and the first hook 15 is lifted away from the nail box 1. When the pressing end is released, the locking spring 18 rebounds, and the first hook 15 returns to its original position.

[0043] like Figures 2 to 5As shown, the staple box 1 of this utility model can be used in an electric stapler. The electric stapler includes a frame 2 with a placement slot 21 on the top surface. The placement slot 21 is used to place staples 10. A pusher plate 22 for pushing the staples 10 is provided in the placement slot 21. One end of the frame 2 is provided with a drive mechanism 23 for driving the pusher plate 22 to move, and the other end is provided with a pressing mechanism 3 for pressing out the staples 10. The placement slot 21 extends from one end of the drive mechanism 23 to one end of the pressing mechanism 3, and the pressing mechanism 3 presses out the staples 10. Correspondingly, both sides of the placement slot 21 are provided with support plates. The staples 10 and the pusher plate 22 are placed on the support plates, so that the staples 10 and the pusher plate 22 can move in the placement slot 21.

[0044] The end of the staple pressing mechanism 3 away from the drive mechanism 23 has a baffle 31 for blocking the staples 10. Near the baffle 31, the staple pressing mechanism 3 has a guide seat 32 for pressing the staples 10. The bottom of the guide seat 32 is located above the placement slot 21. There is a gap between the guide seat 32 and the baffle 31 (the gap is only large enough to accommodate one smallest unit of the staple 10). Above this gap is a staple pressing plate 33 for pressing the staples 10 downwards. The bottom of the staple pressing plate 33 has a binding opening 34. When the pusher plate 22 pushes the staple 10 to the baffle 31, the staple 10 is blocked by the baffle 31, and the top of the staple 10 is pressed by the guide seat 32 above, thus ensuring the stability of the staple 10 during binding. Furthermore, a spring sheet 35 is provided below the guide seat 32. The spring sheet 35 includes a bent portion 351 fixed in the frame 1 and an extension portion 3 integrally connected to one end of the bent portion 351. 52. A staple-pressing channel 321 is formed between the extension 352 and the baffle 31. The top of the staple-pressing channel 321 connects to the gap between the guide seat 32 and the baffle 31, and the bottom of the staple-pressing channel 321 connects to the binding opening 34. Specifically, the extension 352 is inclined, and the upper end of the extension 352 is located outside the staple-pressing channel 321, while the lower end of the extension 352 extends into the staple-pressing channel 321. With this configuration, when the staple plate 33 presses the staple 10 downward so that the staple 10 is located in the staple-pressing channel 321, the bottom of the staple 10 will touch the spring sheet 35 located in the staple-pressing channel 321. The spring sheet 35 always presses the staple 10 located in the staple-pressing channel 321 tightly under its own elastic force to prevent the staple 10 from shifting during the pressing process. The staple plate 33 pushes the staple 10 downward to overcome the elastic force of the spring sheet 35 and pushes the staple 10 towards the binding opening 34 to achieve the binding action.

[0045] The staple outlet 11 corresponds to the position of the placement slot 21. After the staples 10 fall from the staple outlet 11 of the staple box 1, they are placed in the placement slot 21 on the top surface of the frame 2. The frame 2 is provided with a transmission rod 24. One end of the transmission rod 24 is fixedly connected to the piston end of the drive mechanism 23. The other end of the transmission rod 24 is located in the frame 2 near the end of the pressing mechanism 3. A sliding seat 25 is fixedly provided on the transmission rod 24. The drive mechanism 23 drives the sliding seat 25 to move along the length direction of the transmission rod 24. A fixed seat 26 is fixedly provided at the bottom of the pusher plate 22. The fixed seat 26 is sleeved on the transmission rod 24. The sliding seat 25 is located in the fixed seat 26 near the end of the drive mechanism 23. An elastic element 27 is also provided between the end of the fixed seat 26 away from the drive mechanism 23 and the sliding seat 25.

[0046] A drive mechanism 23 for driving the pusher plate 22 is provided at one end of the frame 2, and a pressing mechanism 3 for pressing out the staples 10 is provided at the other end. A staple box 1 is provided on the frame 2, which can hold multiple rows of staples 10. In use, the pusher plate 22 is located close to the drive mechanism 23. A row of staples 10 in the staple box 1 falls into the placement slot 21 under the action of gravity. The drive mechanism 23 controls the movement of the sliding seat 25 to push the elastic element 27, thereby driving the fixed seat 26 and the pusher plate 22 to push the staples 10 to the position of the baffle 31 of the pressing mechanism 3. The top of the staples 10 is pressed by the guide seat 32. The baffle 31 blocks the staples 10 in the placement slot 21, so that the pusher plate 22 and the staples 10 can no longer move. At this time, the staple outlet 11 is blocked by the pusher plate 22 and can no longer fall into the placement slot 21. The drive mechanism 23 then controls the sliding seat 25 to move a certain distance towards the baffle 31.

[0047] Since the pusher plate 22 and the staples 10 are blocked by the baffle 31 of the staple pressing mechanism 3 and can no longer move (the elastic element 27 can no longer push the fixed seat 26 to move), at this time, the sliding seat 25 moves towards the baffle 31, which will cause the sliding seat 25 to compress the elastic element 27 in the fixed seat 26 to a certain extent. Then the drive mechanism 23 stops working. After the drive mechanism 23, the elastic element 27 is in a compressed state. And since one end of the elastic element 27 is against the sliding seat 25, the other end of the elastic element 27 always has a pushing force towards the baffle 31. After one unit of staple 10 is pressed out by pressure plate 33, the pusher plate 22 is only pushed by elastic member 27, so that the pusher plate 22 continues to transport the fixing seat 26, the pusher plate 22 and staple 10 towards the baffle 31, and automatic binding is achieved under the action of pressure plate 33. After all staples 10 are bound, drive mechanism 23 drives pusher plate 22 to reset, and a row of staples 10 in staple box 1 falls into placement slot 21 again under the action of gravity. Drive mechanism 23 repeats the above work, thereby realizing reciprocating automatic binding work.

[0048] Furthermore, a sensing part 221 is fixed on the pusher plate 22. In this embodiment, the sensing part 221 is a straight plate extending upwards. When the sensing part 221 is located near one end of the drive mechanism 23, it is in the initial position. When the sensing part 221 is in the initial position, the pusher plate 22 does not block the nail outlet 11 of the nail box 1, and a row of staples 10 in the nail box 1 automatically falls into the placement slot 21. When the sensing part 221 is located near the nail box 1, all the staples 10 in the placement slot 21 are used up, and at this time the sensing part 221 is in the final position. When the sensing part 221 is located between the drive mechanism 23 and the nail box 1, the pusher plate 22 pushes the staples 10 into the placement slot 21. The sensor 221 is pushed to the position of the baffle 31 of the staple pressing mechanism 3, at which time the sensing part 221 is in the binding position; the frame 2 is also provided with a first sensor 201 for detecting the initial position of the sensing part 221, a first sensor 202 for detecting the binding position of the sensing part 221, and a first sensor 203 for detecting the end position of the sensing part 221. The first sensors 201, 202, and 203 are all controlled and connected to the drive mechanism 23. In this embodiment, the first sensors 201, 202, and 203 can all be conventional photoelectric sensors in the art.

[0049] When the sensing unit 221 is in the initial position, the staples 10 in the staple box 1 fall from the staple outlet 11 into the placement slot 21. When the first sensor 201 detects that the sensing unit 221 is in the initial position, the first sensor 201 sends a signal to the drive mechanism 23, causing the drive mechanism 23 to control the sliding seat 25 to move the pusher plate 22 a certain distance toward the staple pressing mechanism 3, thereby placing the sensing unit 221 in the binding position. When the first sensor 202 detects that the sensing unit 221 is in the binding position, it activates the drive mechanism 23 to control the sliding seat 25 to move the pusher plate 22 a certain distance toward the baffle 31, thereby placing the sliding seat... After the elastic element 27 in the fixed seat 26 is compressed to a certain extent, the drive mechanism 23 stops, and the binding work can begin. When all the staples 10 in the placement slot 21 are used up, the pusher plate 22 is at the end position. When the first sensor 203 detects that the sensing part 221 is at the end position, the first sensor 203 sends a signal to the drive mechanism 23, so that the drive mechanism 23 controls the sliding seat 25 to drive the pusher plate 22 back to its original position and so that the sensing part 221 is back to its initial position. When the first sensor 201 detects that the sensing part 221 is at the initial position, the above actions are repeated to realize automatic reciprocating binding work.

[0050] Furthermore, in this embodiment, the elastic element 27 is preferably a compression spring; the transmission rod 24 of this utility model is preferably a lead screw conventional in the art; the drive mechanism 23 is preferably a lead screw motor conventional in the art capable of controlling the forward and reverse rotation of the lead screw; and the sliding seat 25 is preferably a lead screw nut conventional in the art that is set on the lead screw. This arrangement allows the lead screw motor to drive the lead screw nut to move on the lead screw, thereby driving the fixed seat 26 and the pusher plate 22 to move. It should be noted that the transmission rod 24, drive mechanism 23 and sliding seat 25 in this invention can also adopt other conventional structures in the art, as long as the above effects can be achieved.

[0051] Furthermore, the top of the frame 2 is provided with two second hooks 28 for fixing the nail box 1. The two second hooks 28 are respectively set in the length direction of the nail box 1. Correspondingly, the two second hooks 28 can engage with the corresponding first hooks 15. With this setting, when it is necessary to fix the nail box 1 on the frame 2, you only need to press the pressing end on the direction of the nail box 1 by hand, so that the first hooks 15 are raised. Then, place the nail box 1 between the two second hooks 28, and then release the pressing end. The locking spring 18 returns to its original position, so that the first hooks 15 return to their original position and lock the second hooks 28, so that the second hooks 28 and the first hooks 15 form an engaging engagement, thus fixing the nail box 1 on the frame 2.

[0052] Furthermore, on both sides of the placement slot 21 of the frame 2, corresponding to the position of the nail box 1, there are positioning plates 29 for the nail box 1 to be engaged by the clamping plate 12. The distance between the two positioning plates 29 is greater than or equal to the width of the nail outlet 11 of the nail box 1. When the nail box 1 needs to be installed on the frame 2, the clamping plate 12 is inserted into the placement slot 21 so that the clamping plates 12 on both sides are engaged on the corresponding positioning plates 29 (correspondingly, there is space between the positioning plate 29 and the frame 2 for the clamping plate 12 to extend into). Then the nail box 1 is placed... The second hook 28 is engaged on the frame 2. At this time, since the card plate 12 is engaged on the positioning plate 29 and is in an open state, the staples 10 in the staple box 1 can automatically fall into the placement slot 21. When it is necessary to remove the staple box 1 from the frame 2, press the pressing end with your hand in the direction of the staple box 1 to make the first hook 15 lift up. Then pick up the staple box 1 from the frame 2. After the card plate 12 leaves the positioning plate 29, the hanging rod 13 on the card plate 12 is tensioned under the action of the tension spring 14 to prevent the staples 10 in the staple box 1 from falling out.

[0053] Furthermore, the fastening mechanism 3 also includes a fastening cover 36 for pressing the fastening plate 33 downwards. Specifically, one end of the fastening cover 36 is hinged to the fastening mechanism 3, and the other end of the fastening cover 36 is located above the fastening channel 321. The fastening plate 33 is fixed to the bottom of the fastening cover 36. Pressing down the fastening cover 36 causes the fastening plate 33 to press down for the fastening action. An electric pressure rod (not shown in the figure) for pressing the fastening cover 36 is also provided above the fastening cover 36. Preferably, the top of the fastening cover 36 is provided with a bearing seat 331, and the bearing seat 331 has a first lug 332 and a second lug 333 on both sides. The bearing housing 331 also includes a connecting shaft passing through the first lug 332 and the second lug 333. The connecting shaft is provided with a bearing 334 that cooperates with the electric pressure rod. The electric pressure rod presses the pressure nail cover 36 through the bearing 334 and drives the pressure nail plate 33 to press down to complete one pressure nailing operation. In this embodiment, the electric pressure rod adopts the structure of a conventional electric telescopic rod in the art. As long as it can automatically press the pressure nail cover 36, it is sufficient. This embodiment will not be described in detail here. By setting the bearing 334, the electric pressure rod and the pressure nail cover 36 can achieve sliding contact, avoiding hard contact between the electric pressure rod and the pressure nail cover 36 and causing wear.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
