DETAILED DESCRIPTION

[0025] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0026] Example:

[0027] like Figure 1-Figure 4 As shown, this embodiment provides a mail bag fixing frame, comprising:

[0028] The bag opening tensioning frame 1 is used to sleeve the bag opening of the opened mail bag onto the outside of the bag opening tensioning frame 1, so as to facilitate loading of goods into the mail bag;

[0029] The vertical side frames 2 are rotatably connected to both sides of the bag opening tensioning frame 1, and are preferably connected by conventional hinges without specific restrictions, so that the vertical side frames 2 can rotate relative to the bag opening tensioning frame 1, so that the lower ends of the two vertical side frames 2 can move toward or away from each other; preferably, the upper ends of the two vertical side frames 2 are rotatably connected to the two sides of the bag opening tensioning frame 1, so that when the vertical side frames 2 rotate, the upper part of the bag opening tensioning frame 1 will not be disturbed by the vertical side frames 2;

[0030] The bottom plate 3 is arranged below the bag opening tensioning frame 1, and the two vertical side frames 2 are connected with the bottom plates 3 to support the bottom of the mail bag through the bottom plates 3 to ensure the stability of the mail bag. When the lower ends of the two vertical side frames 2 move away from each other, a gap appears between the two bottom plates 3, which facilitates the mail bag to fall from between the two bottom plates 3, so that workers no longer need to manually remove the mail bag filled with goods from the mail bag fixing frame; and

[0031] The hook 4 is preferably in an inverted V-shaped structure to facilitate hook hooking. The two vertical side frames 2 are fixedly connected with hooks 4 to lift the entire mail bag fixing frame through the hooks 4 on the two vertical side frames 2, so that workers no longer need to carry the mail bags filled with goods to the conveyor belt by hand.

[0032] The present invention has hooks 4 fixedly connected to the two vertical side frames 2, which is convenient for hanging the two hooks 4 through a crane or the like, and then lifting the entire mail bag fixing frame for movement, so that workers are no longer required to carry the mail bags filled with goods to the conveyor belt by hand; wherein, the two vertical side frames 2 are respectively rotatably connected to the two sides of the bag opening tensioning frame 1, and then it is only necessary to control the rotation of the two vertical side frames 2 so that the lower ends of the two vertical side frames 2 move away from each other, and the two bottom plates 3 can generate enough gap for the mail bags to fall, thereby facilitating the direct unloading of the mail bags filled with goods from the mail bag fixing frame. Compared with the prior art, the whole process reduces the workload of workers, reduces labor intensity, and improves convenience and work efficiency.

[0033] As a preferred implementation scheme in this embodiment, it needs to be further explained that both sides of the two vertical side frames 2 are elastically connected by tension springs 5, and the height of the tension springs 5 ​​in the horizontal direction is lower than the height of the bag opening tensioning frame 1 in the horizontal direction. The tension springs 5 ​​are preferably installed in the middle of the vertical side frames 2 close to the bag opening tensioning frame 1. In this way, after controlling the drop of the mail bag, the force applied to the vertical side frames 2 is stopped. The gravity of the vertical side frames 2 themselves and the tension of the tension springs 5 ​​can ensure that the two vertical side frames 2 are reset to the vertical state, so that the two bottom plates 3 move closer to each other and can stably support the lower end of the mail bag.

[0034] As a preferred implementation scheme in this embodiment, it needs to be further explained that each vertical side frame 2 is fixedly connected to both sides with a baffle 6 extending toward the other vertical side frame 2, and the height of the baffle 6 in the horizontal direction is lower than the height of the bag opening tensioning frame 1 in the horizontal direction. The baffle 6 forms a shield on the middle part of the mail bag, thereby further improving the stability of the mail bag in the mail bag fixing frame.

[0035] As a preferred implementation scheme in this embodiment, it needs to be further explained that, fixed seats 7 extending away from the bag opening tensioning frame 1 are fixed on both sides of each vertical side frame 2, and both sides of the hook 4 are respectively connected to two corresponding fixed seats 7 to ensure the stability of the hook 4, and then when the two hooks 4 are pushed toward each other, the two vertical side frames 2 can be driven to rotate by the two hooks 4.

[0036] As a preferred implementation scheme in this embodiment, it needs to be further explained that a side of the vertical side frame 2 away from the bag opening tensioning frame 1 is abutted against a clamping sheet metal 8, and the clamping sheet metal 8 is elastically connected to the vertical side frame 2, so as to clamp the bag opening of the mail bag through the clamping sheet metal 8 and the vertical side frame 2, thereby making the bag opening of the mail bag more stable when it is opened, and making the bag opening of the mail bag more stable when the goods are placed in the mail bag.

[0037] As a preferred implementation scheme in this embodiment, it needs to be further explained that the clamping sheet metal 8 includes an upper clamping plate, a middle adapter plate and a lower connecting plate which are connected in sequence from top to bottom. The lower connecting plate can be a long strip or a long block without specific restrictions. The middle adapter plate is horizontally arranged, the lower end of the upper clamping plate is vertically connected to one side of the middle adapter plate, the upper end of the lower connecting plate is rotatably connected to the other side of the middle adapter plate, the upper clamping plate is abutted against one side of the vertical side frame 2, and the lower connecting plate is elastically connected to the vertical side frame 2. This neither affects the clamping sheet metal 8 in cooperating with the clamping bag opening, nor affects the elastic connection between the clamping sheet metal 8 and the vertical side frame 2.

[0038] As a preferred implementation scheme in this embodiment, it needs to be further explained that a pull ring (not shown in the figure) is connected to the side of the lower connecting plate away from the bag opening tensioning frame 1, so that when it is necessary to clamp the mail bag opening or release the mail bag opening, a gap can be created between the clamping sheet metal 8 and the vertical side frame 2 by pulling the pull ring, thereby facilitating the clamping or release of the mail bag opening, and making the operation of the clamping sheet metal 8 more convenient.

[0039] As a preferred implementation scheme in this embodiment, it needs to be further explained that a partition sheet metal 9 is connected to the side of the vertical side frame 2 away from the bag opening tensioning frame 1, and the partition sheet metal 9 includes a vertical fixed plate and a horizontal limit plate connected from top to bottom, and the horizontal limit plate is supported on the lower end of the middle adapter plate, which is convenient for limiting the middle adapter plate, so that the clamping sheet metal 8 slides along the horizontal limit plate, thereby making the movement of the clamping sheet metal 8 more stable, and the vertical fixed plate is fixedly connected to the side of the vertical side frame 2 away from the bag opening tensioning frame 1, and the vertical fixed plate is abutted against the upper clamping plate, so as to clamp the bag opening of the mail bag through the cooperation of the vertical fixed plate and the upper clamping plate, thereby achieving surface abutment and making the clamping effect better.

[0040] As a preferred implementation scheme in this embodiment, it needs to be further explained that a limit cover 10 is installed on the upper end of the middle adapter plate, and the limit cover 10 is preferably an inverted U-shaped structure, such as Figure 2 As shown, a lifting ring 11 is connected to the limiting cover 10, and a locking rod penetrating into the inside of the limiting cover 10 is arranged at the lower part of the lifting ring 11, a first limiting hole is arranged on the middle adapter plate, and a second limiting hole is arranged on the horizontal limiting plate, and the lower part of the locking rod is inserted into the first limiting hole and the second limiting hole, and when the lower part of the locking rod is inserted into the first limiting hole and the second limiting hole, a gap is reserved between the vertical fixing plate and the upper pressing plate for placing the mail bag opening, and the stability of this state is ensured, and when the mail bag opening needs to be clamped, it is only necessary to pull the lifting ring 11 to disengage the locking rod from the second limiting hole, and the pressing sheet metal 8 will slide toward the vertical fixing plate under the elastic force, thereby clamping the mail bag opening; A first limiting piece 12 located inside the limiting cover 10 is provided in the middle of the locking rod, and a preload spring 13 sleeved on the outside of the locking rod is provided between the first limiting piece 12 and the inner top surface of the limiting cover 10. When it is necessary to move the clamping sheet metal 8, the lifting ring 11 is pulled up to make the lower part of the locking rod disengage from the second limiting hole, and the clamping sheet metal 8 will approach the vertical side frame 2 under the action of elastic force. When it is necessary to unload the mail bag, the clamping sheet metal 8 is controlled to move in the direction away from the vertical fixing plate until the locking rod is again plugged into the second limiting hole under the elastic force of the preload spring 13 and gravity, so that the clamping state of the mail bag mouth can be contacted, so as to facilitate the unloading of the mail bag from the mail bag fixing frame.

[0041] As a preferred implementation scheme in this embodiment, it needs to be further explained that both ends of the vertical side frame 2 are penetrated by sliding shafts 14, so that the sliding shaft 14 can move relative to the vertical side frame 2, and one end of the sliding shaft 14 is connected to the clamping sheet metal 8. The connection here can be a fixed connection or a limited connection. For example, a limiting ring is provided at one end of the sliding shaft 14, and the limiting ring abuts against a side of the clamping sheet metal 8 that is partially away from the vertical side frame 2 to prevent the sliding shaft 14 from being separated from the clamping sheet metal 8. A second limiting member 15 is provided at the other end of the sliding shaft 14, and a clamping spring 16 is provided between the second limiting member 15 and the vertical side frame 2 and is sleeved on the outside of the sliding shaft 14. In the natural state, the clamping spring 16 is in a compressed state. So that in the absence of binding force, the elastic force of the clamping spring 16 can drive the clamping sheet metal 8 to slide in the direction of the separating sheet metal 9, and then clamp the mail bag opening. In this way, after the mail bag opening is sleeved, only the lower part of the locking rod needs to be disengaged from the second limiting hole, and the clamping sheet metal 8 can automatically move away from the vertical side frame 2 under the spring force of the clamping spring 16. When one end of the sliding shaft 14 is limitedly connected to the clamping sheet metal 8, only the lower part of the locking rod needs to be disengaged from the second limiting hole, and the clamping spring 16 in a compressed state can give a thrust to the second limiting member 15, so that the second limiting member 15 drives the sliding shaft 14 to slide, and the sliding shaft 14 drives the clamping sheet metal 8 to move in the direction close to the vertical side frame 2, thereby facilitating the clamping of the mail bag opening or releasing the mail bag opening.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
