The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0031] Please refer to Figures 1 to 3As shown, the automatic magazine opening and closing system 100 of the embodiment of the present invention specifically includes: a magazine material rack 1 and a first locking mechanism 3. The magazine material rack 1 includes a first side plate 11, a second side plate 13, a top plate 12 and a bottom plate 14. The first side plate 11 and the second side plate 13 are arranged in parallel. The bottom plate 14 and the top plate 12 are arranged opposite to each other. The first side plate 11, the top plate 12, the second side plate 13 and the bottom plate 14 jointly enclose at least one loading and unloading opening 4. The first side plate 11 and the second side plate 13 are both provided with clamping grooves 15. The clamping grooves 15 on the first side plate 11 and the second side plate 13 are arranged in pairs opposite to each other. The carrier plate 2 is located in two opposite clamping grooves 15 and remains horizontal. The carrier plate 2 enters and exits the magazine material rack 1 through the loading and unloading opening 4. The first locking mechanism 3 is arranged at at least one of the loading and unloading openings 4. The first locking mechanism 3 includes a first locking portion 31 extending along the gravity direction a. The first locking portion 31 includes a plurality of openings 311 and a stop block 312 adjacent to each opening 311. Wherein, the first locking portion 31 is used to move along the gravity direction a under the action of gravity, so that the stop block 312 moves to the clamping groove 15, and then locks the carrier plate 2; or the first locking portion 31 is used to move in the opposite direction of the gravity direction a, so that the opening 311 moves to the clamping groove 15, and then unlocks the carrier plate 2.
[0032] Please refer to Figure 1 , the first side plate 11, the top plate 12, the second side plate 13 and the bottom plate 14 jointly enclose a frame structure. The same-side ends of the first side plate 11, the top plate 12, the second side plate 13 and the bottom plate 14 jointly enclose the loading and unloading opening 4. The first locking mechanism 3 is arranged on the first side plate 11 and / or the second side plate 13 corresponding to the loading and unloading opening 4.
[0033] In this embodiment, the first locking mechanism 3 is arranged at at least one end of the first side plate 11 and / or the second side plate 13 corresponding to the extending direction of the clamping groove 15.
[0034] In this embodiment, the magazine material rack 1 can be a rectangular metal frame.
[0035] Please refer to again Figure 1 , the corresponding stop block 312 is located above the opening 311. The opening 311 is located at the end of the corresponding clamping groove 15. At this time, the clamping groove 15 is in an unlocked state. The first locking portion 31 moves downward under its own gravity, driving the opening 311 to move downward and leave the clamping groove 15. The stop block 312 moves to the clamping groove 15 to lock the clamping groove 15.
[0036] In this embodiment, along the gravity direction a, the cross-sectional dimension of the opening 311 is greater than or equal to the cross-sectional dimension of the card slot 15. The dimension design of the opening 311 facilitates the insertion and removal of the carrier plate 2 into and out of the card slot 15. The cross-sectional dimension of the stopper 312 is greater than or equal to the cross-sectional dimension of the card slot 15. The dimension design of the stopper 312 can ensure the complete locking of the card slot 15 and provide the locking stability for placing the carrier plate 2 in the card slot 15.
[0037] In this embodiment, the first locking portion 31 is generally a rectangular structure. The first locking portion 31 further includes a connecting strip 313. Each stopper 312 is provided on the connecting strip 313, and the area between two adjacent stoppers 312 forms the opening 311.
[0038] In this embodiment, the opening 311 is generally arc-shaped or rectangular, and can also be other shapes.
[0039] Please refer to Figure 2 , and in combination with Figure 1 and Figure 3 , the first locking portion 31 further includes a first fixing portion 32 provided on the top of the first side plate 11 and / or the second side plate 13, a first guide rod 33 provided on the first fixing portion 32, a second fixing portion 34 provided at the bottom of the first side plate 11 and / or the second side plate 13, and a second guide rod 35 provided at one end of the first locking portion 31 away from the first fixing portion 32. One end of the first locking portion 31 close to the first fixing portion 32 is sleeved on the first guide rod 33, and the first locking portion 31 is configured to move along the first guide rod 33. The second guide rod 35 penetrates through the second fixing portion 34, and the second guide rod 35 is configured to move relative to the second fixing portion 34 along the gravity direction a and the opposite direction of the gravity direction a. One end of the first locking portion 31 is limited by the first fixing portion 32, and the second guide rod 35 connected to the other end is limited by the second fixing portion 34, which can prevent the first locking portion 31 from detaching from the loading and unloading port 4. The stability of the first locking mechanism 3 is improved.
[0040] In this embodiment, when the card slot 15 is in the locked state, the end of the second guide rod 35 away from the first locking portion 31 extends beyond the bottom surface of the magazine material rack 1, as Figure 3 shown; when the card slot 15 is in the unlocked state, the end of the second guide rod 35 away from the first locking portion 31 is flush with the bottom surface of the magazine material rack 1, as Figure 1 shown. In this way, when the magazine automatic opening and closing system 100 is subsequently placed on a horizontal tabletop, the horizontal tabletop will automatically push the second guide rod 35 upward to achieve the unlocking process.
[0041] Please refer to again Figure 2 and, in combination with reference to Figure 1 and Figure 3 , the first locking mechanism 3 further includes a first elastic member 36 sleeved on the first guide rod 33. Two ends of the first elastic member 36 respectively abut against the first fixing portion 32 and the first locking portion 31. When the first locking portion 31 moves in the opposite direction of the gravity direction a to unlock the card slot 15, the first elastic member 36 is in a compressed state. In this way, after the magazine material rack 1 is lifted, the first locking portion 31 moves along the gravity direction a under the dual action of gravity and the elastic restoring force of the first elastic member 36, so that the stop block 312 moves to the card slot 15 to lock the card slot 15. The locking speed is fast, and during the movement of the magazine material rack 1, due to the abutment of the first elastic member 36, the first locking portion 31 will not accidentally unlock the card slot 15, improving the locking stability of the first locking mechanism 3.
[0042] In this embodiment, the first elastic member 36 is a spring.
[0043] In this embodiment, when the magazine automatic opening and closing system 100 is placed on a horizontal tabletop, or when the magazine automatic opening and closing system 100 is lifted, both the first side plate 11 and the second side plate 13 are disposed substantially perpendicular to the horizontal plane.
[0044] In this embodiment, the number of the first locking mechanisms 3 is two, and the two first locking mechanisms 3 are respectively disposed on the first side plate 11 and the second side plate 13 corresponding to the same feeding and discharging port 4. By respectively providing a first locking portion 31 at two relatively arranged card slots 15, the locking of the carrier plate 2 is more stable.
[0045] Please refer to Figures 1 to 3 , during the specific use process, after the magazine automatic opening and closing system 100 is lifted, the first locking portion 31 drives to move along the gravity direction a under the dual action of its own gravity and the elastic restoring force of the first elastic member 36, thereby driving the stop block 312 to move to the card slot 15 to lock the carrier plate 2, as Figure 3 shown. When the magazine automatic opening and closing system 100 is placed on a parallel tabletop, the second guide rod 35 abuts against the parallel tabletop, and the parallel tabletop abuts against the second guide rod 35, pushing the second guide rod 35 in the opposite direction of the gravity direction a, so that the first locking portion 31 moves in the opposite direction of the gravity direction a, so that the stop block 312 leaves the card slot 15, and the opening 311 moves to the card slot 15, finally unlocking the carrier plate 2 in the card slot 15, as Figure 1 shown.
[0046] Please refer to again Figure 1When the automatic opening and closing system 100 of the magazine clip is used in some scenarios, the two opposite ends of the magazine clip material rack 1 need to be opened simultaneously. At this time, the magazine clip material rack 1 needs to be provided with two inlet and outlet ports (4, 6), and the first locking mechanism 3 is provided at one inlet and outlet port 4 or both inlet and outlet ports 4.
[0047] In this embodiment, the first locking mechanism 3 is disposed at one of the feed inlets and outlets 4 .
[0048] See also Figures 4 to 6 , combined with reference Figure 1 The automatic opening and closing system 100 of the magazine further includes a second locking mechanism 5 , which is disposed at the feed inlet and outlet 6 on the opposite side of the first locking mechanism 3 .
[0049] In this embodiment, the second locking mechanism 5 is a manual locking mechanism, and the second locking mechanism 5 is manually opened and closed to unlock and lock the card slot 15. The automatic clip opening and closing system 100 is automatically locked or opened on one side, and manually forced to lock or open on the other side, so that both ends of the automatic clip opening and closing system 100 can be opened to connect the machine, and at the same time, it can prevent the operator from exceeding the track range of the card slot 15 when placing the carrier, thereby achieving a foolproof effect.
[0050] See also Figure 6 , combined with reference Figure 4 and Figure 5 The second locking mechanism 5 includes a second locking portion 51 extending along the gravity direction a, a first latching position 52 arranged on the side of the magazine material rack 1 close to the inlet and outlet port 6, and a second latching position 53 arranged on the side of the magazine material rack 1 away from the inlet and outlet port 6. The second locking portion 51 is used to engage with the first latching position 52 or the second latching position 53, thereby locking or unlocking the slot 15.
[0051] In this embodiment, the second locking portion 51 includes a locking rod 511 extending along the gravity direction a, a fixing member 512 provided at one end of the locking rod 511 close to the top plate 12, a rotating shaft 513 connecting the fixing member 512 and the magazine material rack 1, a second elastic member 514 sleeved on the rotating shaft 513, and a rotating portion 515 provided at one end of the locking rod 511 close to the bottom plate 14. The rotating portion 515 is rotatably connected to the magazine material rack 1, and the fixing member 512 is used to drive the locking rod 511 to rotate around the rotating shaft 513, so that the locking rod 511 is engaged with the first clamping position 52 or the second clamping position 53, thereby locking or unlocking the card slot 15. By manually swinging the locking rod 511, the locking rod 511 rotates around the rotating shaft 513 along the gravity direction a, so that the locking rod 511 rotates to one side of the card slot 15 close to the feeding and discharging port 6 and is engaged in the first clamping position 52 to lock the card slot 15; or the locking rod 511 rotates to one side of the card slot 15 away from the feeding and discharging port 6 and is engaged in the second clamping position 53 to unlock the card slot 15.
[0052] Please refer to Figure 6 , and in combination with Figure 4 and Figure 5 , in this embodiment, the rotating portion 515 and the locking rod 511 are of an integral structure. The rotating portion 515 is generally of a U-shaped structure, with one end connected to the locking rod 511 and the other end rotatably fixed on the magazine material rack 1. The U-shaped structure design facilitates the rotation of the locking rod 511.
[0053] In this embodiment, the second locking mechanism 5 is provided on the first side plate 11 and the second side plate 13, and the bottoms of the first side plate 11 and the second side plate 13 extend downward to block the bottom of the rotating portion 515. After the rotating portion 515 and the locking rod 511 are engaged with the first clamping position 52 or the second clamping position 53, the rotating portion 515 will be blocked by the bottoms of the first side plate 11 and the second side plate 13, so that the locking rod 511 will not automatically come out after being engaged with the first clamping position 52 or the second clamping position 53, improving the locking stability of the second locking mechanism 5.
[0054] In this embodiment, the second elastic member 514 can be a spring. One end of the second elastic member 514 abuts against the fixing member 512, and the other end abuts against the locking rod 511, which can improve the tightness of the second locking portion 51 during the locking or unlocking process, prevent the locking rod 511 from automatically coming out in the first clamping position 52 or the second clamping position 53, and improve the stability of the second locking portion 51.
[0055] Please refer to again Figure 1 , the magazine automatic opening and closing system 100 further includes a handle 7 provided on the magazine material rack 1. By lifting the handle 7 by hand, the magazine automatic opening and closing system 100 can be moved.
[0056] Compared with the prior art, the first locking mechanism adopted by the magazine automatic opening and closing system provided by the present invention is a gravity self-locking structure, which can realize the automatic opening and closing of the magazine material rack, avoiding the sliding out and dropping of the carrier plate caused by manual operation errors, or causing the magazine material rack to tilt and turn over, resulting in product damage or loss. Moreover, the gravity self-locking operation is convenient, the locking mechanism is simply designed, without the need to connect a driving mechanism, with low cost, easy disassembly and maintenance, and the locking mechanism has strong versatility and can be applied to various magazine structures.
