DETAILED DESCRIPTION

[0028] Example 1

[0029] like Figure 1 and Figure 2 As shown, the utility model provides an easily detachable paper packaging corner protector, comprising four upper corner protectors 1 and four lower corner protectors 2, which correspond to eight corners of the packaging carton respectively. The easily detachable paper packaging corner protector also includes:

[0030] A telescopic assembly 3 is arranged between the upper corner guards 1 and between the lower corner guards 2 to adjust the distance between the upper corner guards 1 and between the lower corner guards 2 respectively;

[0031] A pressing component 4 is arranged between the upper corner protector 1 and the lower corner protector 2, and the upper corner protector 1 is pressed down by the pressing component 4 to fix the upper corner protector 1 and the lower corner protector 2 on the packaging carton;

[0032] The straight line maintaining component 5 is also arranged between the upper corner protector 1 and the lower corner protector 2 to maintain the relative straight line movement between the upper corner protector 1 and the lower corner protector 2, so as to cooperate with the clamping assembly 4 for use.

[0033] When installing the corner protector, first place the carton in the area surrounded by the upper corner protector 1 and the lower corner protector 2, and then adjust the distance between the upper corner protector 1 and the lower corner protector 2 by the telescopic component 3, so that the distance between the upper corner protector 1 and the lower corner protector 2 is the same as the length of the carton, first put the lower corner protector 2 close to the bottom four corners of the carton, and then press the upper corner protector 1 down by the clamping component 4, so that the upper corner protector 1 is close to the top four corners of the carton, and the straight line maintaining component can move up and down on the upper corner protector 1 to maintain the straight line movement between it and the lower corner protector 2. When disassembling, you only need to release the fixation between the clamping component 4 and the telescopic component 3 on the upper corner protector 1 and the lower corner protector 2, so that the corner protector can be easily separated from the carton as a whole by unfolding the corner protector, and its disassembly is completed. It is very convenient for multiple uses of the corner protector, and when the corner protector is installed on the carton, it is also supported vertically by the clamping component 4, which can better improve the strength of the carton and prevent the carton from being deformed by pressure.

[0034] Example 2

[0035] This embodiment further illustrates the telescopic assembly 3 and the pressing assembly 4 in the embodiment 1. Figure 1 , Figure 2 and Figure 3 As shown, the telescopic assembly 3 includes a hollow shell 301 fixed on the upper corner guard 1 and the lower corner guard 2 respectively, the opposite surfaces between the hollow shells 301 are open, the interior of the hollow shells 301 is movably connected with an inner block 302, and the inner blocks 302 are fixedly connected with a connecting rod 303, the top of the hollow shell 301 is arranged with a plurality of through holes 304 in an array, the top of the inner block 302 is provided with a screw hole 305, the opening of the through hole 304 is provided with a screw, and the screw is sequentially passed downward through the through hole 304 at the corresponding position and then rotated clockwise to be installed in the screw hole 305, that is, the two hollow shells 301 are pulled back and forth, from When adjusting the distance between the two upper corner guards 1 or the lower corner guards 2, the two hollow shells 301 will change their positions relative to the connecting rod 303 and the inner block 302 when moving. When the distance adjustment is completed, two screws are respectively passed through the through holes 304 at the corresponding positions of the hollow shells 301 on both sides and then rotated clockwise to install them into the screw holes 305 on the inner block 302, so that the inner block 302 and the hollow shell 301 can be fixed. The two inner blocks 302 are connected by the connecting rod 303, so that an integral structure is formed between the two hollow shells 301, and the position between the two hollow shells 301 is fixed.

[0036] Furthermore, the inner bottom end of the hollow shell 301 is fixedly connected with a guide rail A306, and the bottom end of the inner block 302 is slidably connected in the guide rail A306 via a slider A307, that is, the movable block is slidably connected in the hollow shell 301 via the guide rail A306 and the slider A307. In this way, when the two hollow shells 301 are pulled, with the restrictions of the two, the movable block will not separate from the hollow shell 301, which is more convenient for operation.

[0037] The following is the specific structure of the clamping assembly 4; the clamping assembly 4 includes a screw 402 connected to the telescopic assembly 3 on the lower corner guard 2 through a horizontal plate A401, and a through slot block 403 is movably connected to the outer wall of the screw 402. The through slot block 403 is connected to the upper corner guard 1 through a connecting plate and a connecting assembly 6. The outer wall of the screw 402 is located on the upper and lower sides of the through slot block 403 and is threadedly connected with nuts 404, that is, the through slot block 403 is pushed to move downward, thereby driving the four upper corner guards 1 to move downward. When the upper corner guard 1 is against the top of the carton, the nuts 404 located on the upper and lower sides of the ordinary block on the screw 402 are rotated clockwise, and the upper and lower sides of the through slot block 403 are clamped by the two nuts 404, thereby fixing the height of the through slot block 403. At this time, the carton is supported by the through slot block 403 with a fixed height by the screw 402 and the nut 404, and the strength is higher.

[0038] Example 3

[0039] This embodiment further illustrates the straight line maintaining component 5 and the connecting component 6 in embodiment 1. Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the straight line maintaining component 5 includes a telescopic rod 501 respectively fixed between the upper corner guard 1 and the lower corner guard 2, the end of the telescopic rod 501 is connected to the telescopic component 3 on the lower corner guard 2 through a cross plate B502, and the head of the telescopic rod 501 is connected to the telescopic component 3 on the upper corner guard 1 through a connecting component 6, that is, when the lower corner guard 2 moves up and down, the telescopic rod 501 will expand and contract accordingly to maintain the relative linear motion between the upper corner guard 1 and the lower corner guard 2.

[0040] The following is a specific structure of the connection component 6: the connection component 6 includes a lower opening slot seat 601, and an insert block 602 that can be inserted into the lower opening slot seat 601. The side end of the lower opening slot seat 601 is provided with a circular hole 603 that communicates with the internal cavity of the lower opening slot seat 601. The side end of the insert block 602 is provided with a groove 604. The inner surface of the groove 604 is connected to the movable plate 606 through a spring 605. The movable plate 606 is provided with a limiting cylinder 607 that can be inserted into the circular hole 603 on the side opposite to the spring 605. Figure 1 and 2 As shown, there are multiple insert blocks 602 and lower open slot seats 601. The lower open slot seat 601 is fixed on the upper corner protector 1 and the telescopic component 3 connected to the lower corner protector 2. The insert block 602 is fixed and fixed to the head of the telescopic rod 501 through the connecting plate and the through slot block 403. When assembling, first press the limiting cylinder 607 into the groove 604 on the insert block 602. The limiting cylinder 607 drives the movement of the movable plate 606 and squeezes the spring 605 at the same time. Then, the insert block 602 is inserted into the lower open slot seat 601. After it is fully inserted, the limiting cylinder 607 is aligned with the through hole 304 on the lower open slot seat 601. The limiting cylinder 607 is no longer blocked, and the spring 605 extends in the opposite direction, thereby resetting the movable plate 606 and the limiting cylinder 607, that is, the limiting cylinder 607 is inserted into the circular hole 603, completing the fixation of the lower opening slot seat 601 and the plug block 602, and also completing the above-mentioned connection (that is, the connection between the telescopic rod 501 and the upper telescopic component 3 of the upper corner protector 1, and the connection between the through-slot block 403 and the upper corner protector 1). Similarly, by using a rod-shaped object such as chopsticks to push the limiting cylinder 607 out of the circular hole 603, the plug block 602 and the lower opening slot seat 601 can be disassembled. The disassembly and assembly are very simple, so that the upper corner protector 1 and the lower corner protector 2 can be separated. When damaged, they can be replaced instead of being completely scrapped.

[0041] The utility model has made improvements on the basis of the above-mentioned connecting component 6, and the guide rails B608 are fixedly connected to the inner sides of the groove 604, and the two sides of the movable plate 606 are slidably connected in the guide rails B608 through sliders B609, that is, the sliders B609 and the guide rails B608 are used to maintain the movable plate 606 and limit the linear movement of the cylinder to avoid the cylinder from tilting when moving back and forth, so that it cannot be inserted into the circular hole 603 to complete the corresponding connection.

[0042] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
