Description
Technical Field
[0001] The utility model relates to a cigarette frame which is convenient for folding and unfolding, and belongs to the technical field of cigarette frame tools. Background Art
[0002] The traditional storage and transportation method of tobacco is mainly based on stacking, loose tobacco transportation or storage and transportation in cigarette packs. This method occupies a large area and land resources are not effectively utilized. The tobacco leaves are prone to mildew due to poor ventilation caused by stacking, and are prone to oil release due to long-term stacking and squeezing. In addition, direct stacking, transportation, and loading and unloading of tobacco leaves many times can easily cause the tobacco leaves to break, reduce the tobacco leaf output rate, increase operating costs, and low warehouse space utilization, resulting in space waste.
[0003] Therefore, the existing method of storing tobacco leaves using cigarette frames is to design the cigarette frames into a foldable structure in order to save the placement space of the cigarette frames so as to facilitate the stacking of the cigarette frames during the vacancy period. The structure includes a bracket, on which a tubular supporting foot is provided, and a column is installed in the supporting foot. The column can move up and down along the supporting foot and rotate toward the inner side of the bracket to achieve folding. A main side panel is provided between the columns, and secondary side panels are hinged on both sides of the bracket adjacent to the main side panels. The upper end of the secondary side panel is snap-connected with the column. At the same time, a vertical limiting groove is provided in the middle of the supporting foot, and a pin shaft cooperating with the limiting groove is provided at the lower end of the column. The pin shaft is in the vertical position. When the column moves up and down, the column is limited; a limiting notch is provided at the upper end of the supporting foot, and a fixing column is provided on the column. When the column is in a vertical installation state, the fixing column and the limiting notch are mutually limited, and an opening is provided in the middle part of the outer side of the supporting foot, and the opening is used for the lower part of the column to be rotated out or rotated in when the column is rotated, folded or vertically unfolded. Although such a structure can realize the folding of the cigarette frame, there are some shortcomings in the folding process. Specifically, before folding the upright main side panel, the column needs to be moved upward first, and the lower part of the column needs to be moved to the upper side of the opening provided in the middle part of the outer side of the supporting foot before the column can be rotated and folded. Figure 1-Figure 5 Although such a structure can fold the main side panels, after the upright column and the main side panels are lifted as a whole, the pin shaft has no support in the limit slot, so when the main side panels are rotated as a whole, they must be controlled and held manually. The main side panels and the upright column are made of steel structure as a whole, which is heavy and difficult to control. Therefore, it is time-consuming and laborious to rotate and fold or rotate and stand.
[0004] Therefore, there is a need for a cigarette frame that can facilitate the rotational folding and upright unfolding of the main side panels of the cigarette frame. Utility Model Content
[0005] In view of this, the purpose of the utility model is to provide a cigarette frame that is easy to fold and unfold, which can facilitate the rotational folding and upright unfolding of the main side panels of the cigarette frame; and can overcome the shortcomings of the prior art.
[0006] The purpose of this utility model is achieved through the following technical solutions:
[0007] The utility model discloses a cigarette frame which is easy to fold and unfold. The cigarette frame comprises a bracket, on which a tubular supporting foot is arranged, and inside the supporting foot a column is installed. The column can move up and down along the supporting foot and rotate toward the inner side of the bracket to realize folding. A main side plate is arranged between the columns, and secondary side plates are hinged on both sides of the bracket adjacent to the main side plates, and the upper ends of the secondary side plates are snap-connected with the columns. A rotating supporting device is arranged on the supporting foot between the columns, and the rotating supporting device supports the column after it moves upward so as to facilitate the rotating folding or vertical unfolding of the column.
[0008] In the above-mentioned, a vertical limit groove is provided in the middle part of the supporting foot, and a pin shaft cooperating with the limit groove is provided at the lower end of the column, and the pin shaft limits the column when the column moves up and down; a limit recess is provided at the upper end of the supporting foot, and a fixed column is provided on the column, and the column limits the fixed column and the limit recess to each other in the vertical installation state, and an opening is provided in the middle part of the outer side of the supporting foot, and the opening is used for the lower part of the column to be rotated out or rotated in when the column is rotated folded or vertically unfolded.
[0009] The above-mentioned rotating support device includes an automatic support component and a control component provided on the upper side of the limit groove. The automatic support component automatically supports the pin shaft when the pin shaft moves to the upper part of the limit groove, and the control component unlocks the support of the pin shaft by the automatic support component when the column needs to be lowered.
[0010] The above-mentioned automatic support component includes a shell installed on the outer wall of the supporting foot, and a lock tongue supporting the pin shaft is arranged in the shell. The lower surface of the lock tongue is provided with a chamfer. When the pin shaft moves upward, the lock tongue automatically shrinks to avoid the pin shaft passing through, and a compression spring is provided between the lock tongue and the inner side of the shell to control the automatic return of the lock tongue.
[0011] As mentioned above, a pull handle connected to the outside of the housing is provided at the inner end of the lock tongue, and the control component controls the pull handle to be pulled outward or automatically returned.
[0012] The above-mentioned control component includes a guide plate provided at the outer end of the pull handle, and a pressing block cooperating with the guide plate is provided on the supporting foot. The pressing block pushes the guide plate outward by pressing downward, so that the pull handle drives the locking tongue to retract. An automatic resetting device of the pressing block is provided on the supporting foot, and a pressing rod is connected between the pressing blocks on the front and rear sides.
[0013] As mentioned above, the automatic support assembly is located on both sides of the supporting foot to support the two ends of the pin shaft respectively, and the automatic reset device includes a connecting rod used to connect the lower pressure blocks on both sides of the supporting foot, a vertical guide rod is provided on the lower surface of the connecting rod, a fixing plate is provided on the supporting foot, a guide hole that cooperates with the guide rod is provided on the fixing plate, and a spring in a compressed state is provided on the guide rod between the connecting rod and the fixing plate.
[0014] As mentioned above, a foot is provided on the supporting foot to cooperate with the upper end of another cigarette frame column.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model can provide fixed-axis support for the upright column after it is moved upward into position through the rotating support device, so as to facilitate the rotation of the main column, thereby facilitating rotational folding or rotational vertical unfolding.
[0017] 2. Specifically, the automatic support assembly can support the pin after the upward movement. After the pin is supported, it can be convenient to rotate and fold or rotate and unfold in the vertical direction from the folded state, which is more convenient to operate compared with the prior art. At the same time, after the vertical rotation and unfolding, the automatic support assembly is unlocked and supported by the control assembly, which is convenient for the pin to fall, so that the lower end of the column falls into the support foot, and the support foot is limited to the lower end of the column. At the same time, the clamping limit of the limit notch of the upper end of the fixed column and the support foot is also realized. When the pin moves upward, through the chamfer of the lock tongue, the lock tongue shrinks inward under the force of the upward movement of the pin, so that the pin moves to the upper side of the lock tongue. After the pin passes through the lock tongue, the lock tongue automatically returns to its position under the action of the compression spring, thereby realizing the support of the lock tongue to the pin. After the pin is supported, the column and the main side plate can be rotated along the fixed axis of the pin shaft as a whole, so as to facilitate rotation and folding or rotation and unfolding in the vertical direction, replacing the problem of the current technology of controlling the rotation point of the main side plate by manpower. When the main side panel needs to be vertically unfolded, the pressing block is pressed down by stepping on the pressing rod. During the pressing process of the pressing block, the guide plate is pushed outward, so that the pull handle drives the lock tongue to retract, thereby making room for the pin shaft to move downward. The pin shaft moves downward, and the slots provided at the lower ends of the column and the supporting feet are vertically limited, and the fixed column and the limiting recess cooperate with each other to limit the position.
[0018] 3. The spring in the compressed state can automatically push the connecting rod to drive the lower pressure block upward and reset after the lower pressure block is pressed down.

DETAILED DESCRIPTION
[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.
[0035] like Figure 6-Figure 12 The foldable cigarette rack of the present invention is convenient for folding and unfolding. The foldable cigarette rack comprises a bracket 1, a tubular supporting foot 2 is provided on the bracket 1, a column 3 is installed in the supporting foot 2, and an ankle 10 is provided on the supporting foot 2 to cooperate with the upper end of the column 3 of another cigarette rack. This makes it convenient for the cigarette racks to be stacked up and down after loading cigarettes. The ankle 10 cooperates with the column 3 and can also prevent the cigarette racks from being displaced after stacking. The column 3 can move up and down along the supporting foot 2 and rotate toward the inner side of the bracket 1 to achieve folding. A main side plate 4 is provided between the columns 3, and auxiliary side plates 5 are hinged on both sides of the bracket 1 adjacent to the main side plates 4. The upper ends of the auxiliary side plates 5 and the columns 3 are connected by buckles 6. A rotating support device is provided on the supporting foot 2, and the rotating support device supports the column 3 after it moves upward so as to facilitate the rotation and folding of the column 3 or the vertical unfolding. With such a structure, the column moved upward into position can be fixedly supported by the rotating support device to facilitate the rotation of the main column, thereby facilitating the rotation and folding or the rotation and vertical unfolding.
[0036] Specifically, a vertical limit groove 2-1 is provided in the middle of the supporting foot 2, and a pin shaft 2-2 cooperating with the limit groove 2-1 is provided at the lower end of the column 3, and the pin shaft 2-2 limits the column 3 when the column 3 moves up and down; a limit recess 2-3 is provided at the upper end of the supporting foot 2, and a fixed column 2-4 is provided on the column 3, and the column 3 limits the fixed column 2-4 and the limit recess 2-3 to each other in the vertical installation state; an opening 2-5 is provided in the middle part of the outer side of the supporting foot 2, and the opening 2-5 is used for the lower part of the column 3 to be rotated out or rotated in when the column 3 is rotated folded or vertically unfolded.
[0037] Furthermore, the rotating support device includes an automatic support component 7 and a control component 8 provided on the upper side of the limiting groove 2-1. The automatic support component 7 automatically supports the pin shaft 2-2 when the pin shaft 2-2 moves to the upper part of the limiting groove 2-1. The control component 8 unlocks the support of the automatic support component 7 to the pin shaft 2-2 when the column 3 needs to be lowered. With such a structure, the automatic support component 7 can support the pin shaft 2-2 after it moves upward. After the pin shaft 2-2 has support, it can be easily rotated and folded or rotated and unfolded in the vertical direction from the folded state. Compared with the prior art, it is easier to operate. At the same time, after the vertical rotation and unfolding, the automatic support component 7 is unlocked and supported by the control component 8, so that the pin shaft 2-2 falls, so that the lower end of the column 3 falls into the supporting foot 2, so as to realize the limiting of the lower end of the column 3 by the supporting foot 2, and at the same time, the clamping limiting of the fixed column 2-4 and the limiting recess 2-3 at the upper end of the supporting foot 2 is also realized.
[0038] Furthermore, the automatic support assembly 7 includes a shell 7-1 mounted on the outer wall of the support foot 2, a lock tongue 7-2 supporting the pin shaft 2-2 is arranged in the shell 7-1, a chamfer 7-3 is arranged on the lower surface of the lock tongue 7-2, and the chamfer 7-3 automatically shrinks the lock tongue 7-2 to avoid the pin shaft 2-2 passing through when the pin shaft 2-2 moves upward, and a compression spring 7-4 for controlling the automatic return of the lock tongue 7-2 is arranged between the lock tongue 7-2 and the inner side of the shell 7-1. With this structure, when the pin shaft 2-2 moves upward, the lock tongue 7-2 is locked through the chamfer 7-3 of the lock tongue 7-2. Under the force of the upward movement of the pin shaft 2-2, the lock tongue 7-2 contracts inwardly, so that the pin shaft 2-2 moves to the upper side of the lock tongue 7-2. After the pin shaft 2-2 passes through the lock tongue 7-2, the lock tongue 7-2 automatically returns to its original position under the action of the compression spring 7-4, thereby realizing the support of the lock tongue 7-2 for the pin shaft 2-2. After the pin shaft 2-2 has the support, the column 3 and the main side panel 4 as a whole can rotate along the fixed axis of the pin shaft 2-2, thereby facilitating rotational folding or rotational unfolding in the vertical direction, replacing the problem of the current technology controlling the rotation point of the main side panel 4 by manpower.
[0039] Furthermore, a pull handle 7-5 connected to the outside of the shell 7-1 is provided at the inner end of the lock tongue 7-2, and a control component 8 controls the pull or automatic return of the pull handle 7-5; specifically, the control component 8 includes a guide plate 8-1 provided at the outer end of the pull handle 7-5, a pressing block 8-2 cooperating with the guide plate 8-1 is provided on the support foot 2, the pressing block 8-2 presses down to push the guide plate 8-1 outward, so that the pull handle 7-5 drives the lock tongue 7-2 to retract, and an automatic resetting device 9 of the pressing block 8-2 is provided on the support foot 2, and the pressing blocks 8-2 on the front and rear sides are pressed downward to push the guide plate 8-1 outward. A pressing rod 8-3 is connected between the blocks 8-2. With such a structure, when the main side plate 4 needs to be vertically unfolded, the pressing block 8-2 is pressed down by stepping on the pressing rod 8-3. During the pressing process of the pressing block 8-2, the guide plate 8-1 is pushed outward, so that the pull handle 7-5 drives the lock tongue 7-2 to contract, thereby making room for the pin shaft 2-2 to move downward. The pin shaft 2-2 moves downward, and the lower end of the column 3 and the lower end of the supporting foot 2 are provided with a card groove for vertical limitation, and the fixed column 2-4 and the limiting recess 2-3 cooperate with each other to limit.
[0040] Furthermore, the automatic support component 7 is located on both sides of the supporting foot 2 to support the two ends of the pin shaft 2-2 respectively, and the automatic reset device 9 includes a connecting rod 9-1 for connecting the lower pressure blocks 8-2 on both sides of the supporting foot 2, and a vertical guide rod 9-2 is provided on the lower surface of the connecting rod 9-1, and a fixed plate 9-3 is provided on the supporting foot 2. A guide hole that cooperates with the guide rod 9-2 is provided on the fixed plate 9-3, and a compressed spring 9-4 is provided on the guide rod 9-2 between the connecting rod 9-1 and the fixed plate 9-3. With this structure, the compressed spring 9-4 can automatically push the connecting rod 9-1 to reset the lower pressure block 8-2 upward after the lower pressure block 8-2 is pressed down.
[0041] When in use, when the cigarette frame needs to be folded, first unlock it through the buckle 6, fold the secondary side panel 5 first, then move the column 3 and the main side panel 4 upward as a whole, move the pin 2-2 to the upper side of the lock tongue 7-2, and the lock tongue 7-2 supports the pin 2-2, so that the column 3 and the main side panel 4 can be rotated as a whole with the pin 2-2 to achieve rotational folding; when the side panel needs to be unfolded in the vertical direction, first rotate the column 3 and the main side panel 4 as a whole with the pin 2-2 to the vertical, and then press down The rod 8-3 presses the pressing block 8-2 downward. During the pressing process of the pressing block 8-2, the guide plate 8-1 is pushed outward, so that the pull handle 7-5 drives the lock tongue 7-2 to retract, making room for the pin shaft 2-2 to move downward. The pin shaft 2-2 moves downward, and the lower end of the column 3 is vertically limited with the side wall of the lower part of the supporting foot 2, and the fixed column 2-4 and the limiting recess 2-3 cooperate with each other to limit, completing the upright installation of the main side panel 4, and then the secondary side panel 5 is connected to the column 3 through the buckle 6 to realize the expansion of the cigarette frame side panel.
[0042] The above is only a preferred embodiment of the utility model, and does not limit the confidentiality of the utility model in any form.
