DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, a box with an anti-tipping pull rod 21 includes a box body 2, and hidden support components are installed on the front and rear sides of the box body 2. The hidden support component includes hidden grooves 31 symmetrically arranged on the front and rear sides of the box body 2, and support feet 32 ​​are rotatably arranged in the hidden grooves 31, and the support feet 32 ​​are provided with first buffer pads 33; the two symmetrically arranged hidden grooves 31 are also provided with limiting mechanisms for lowering the support feet 32 ​​or preventing the support feet 32 ​​from being lowered; the front and rear sides of the box body 2 are symmetrically installed with a first anti-collision frame 41 and a second anti-collision frame 42 in sequence from top to bottom, and the first anti-collision frame 41 and the second anti-collision frame 42 both have a second buffer pad 43; a retractable and adjustable pull rod 21 is also installed on the box body 2. By setting up a hidden support component, the support feet 32 ​​can be placed in the hidden groove 31 for storage or unfolding to support the box body 2, which is beneficial to preventing the box body 2 from tipping over, and has good protection and support effects; at the same time, a first anti-collision frame 41 and a second anti-collision frame 42 are set on the front and back sides of the box body 2, as well as a second buffer pad 43 on the first anti-collision frame 41 and the second anti-collision frame 42. If the box body 2 is impacted or falls to the ground, it is beneficial to reduce the impact on the box body 2 and play a certain buffering role, thereby protecting the box body 2 to a certain extent, avoiding damage to the box body 2, being safer, and extending the service life of the box body 2.

[0022] The limiting mechanism includes two mounting blocks 51 arranged on the outer side of the two hidden grooves 31 and an adjustment frame 52 located between the two hidden grooves 31. A first groove 53 is symmetrically provided in the adjusting frame 52. A first spring 54 is fixedly connected to the bottom of the first groove 53. A telescopic rod 55 is fixed on the first spring 54. The mounting block 51 also has a second groove 511. A rest block 512 is also installed at the bottom of the second groove 511 of the mounting block 51. One end of the telescopic rod 55 is fixed on the first spring 54, and the other end is inserted into the second groove 511 of the mounting block 51 and rests against the rest block 512. An adjustment hole 521 is provided on the outer side of the adjusting frame 52, and a limit adjustment rod 551 is installed on the telescopic rod 55. The limit adjustment rod 551 passes through the adjustment hole 521 and moves left or right on the adjustment hole 521 by the operator.

[0023] With the above structure, when the supporting foot 32 is hidden and stored in the hidden groove 31, the first spring 54 in the adjustment frame 52 is affected by the elastic potential energy. Under normal circumstances, the telescopic rod 55 is inserted into the second groove 511 of the installation frame and abuts against the abutment block 512. When the operator wants to support the box body 2, the operator holds the limit adjustment rod 551 and moves it away from the installation block 51, driving the telescopic rod 55 in the adjustment frame 52 to move away from the installation block 51. At this time, when the telescopic rod 55 moves toward the first spring 54, a squeezing force is generated on the first spring 54, causing the first spring 54 to contract.

[0024] When the telescopic rod 55 is retracted to the inner side of the hidden groove 31 and cannot abut against the supporting foot 32, the supporting foot 32 can be taken out from the hidden groove 31 for support. This structural setting is conducive to simple structure, convenient storage, and greater practicality.

[0025] like Figures 1 to 5 As shown, third grooves 61 for conveniently grabbing the supporting foot 32 are further provided on the left and right sides of the hidden groove 31 , and fourth grooves 62 matching the third grooves 61 are further provided on the left and right sides of the supporting foot 32 .

[0026] Through the above structure, when the operator takes the supporting foot 32 out of the hidden groove 31 , the third groove 61 and the fourth groove 62 are provided, which is conducive to more convenient removal of the supporting foot 32 and has strong practicality.

[0027] like Figures 1 to 5As shown, the hidden groove 31 is also provided with a flip and tightening assembly, which includes a rotating rod 71 mounted on the hidden groove 31. The rotating rod 71 is equipped with a tightening block 72, one side of which abuts against the outer surface of the support leg 32. By providing the tightening block 72, in conjunction with the telescopic rod 55, one end of the support leg 32 is further limited, and the limiting effect is better.

[0028] like Figures 1 to 5 As shown, the front and rear sides of the box body 2 are all equipped with hanging rods 22. By arranging the hanging rods 22, it is convenient to hang some hangable items on the luggage box, which has a wider range of uses and is more practical.

[0029] like Figures 1 to 5 As shown, the bottom corners of the box body 2 are further provided with protective covers 23 for protecting the bottom corners of the box body 2. By providing the protective covers 23, when the corners of the box body 2 come into contact with the ground, the corners of the box body 2 are effectively protected, thereby preventing damage to the corners of the box body 2 and extending the service life of the box body 2.

[0030] like Figures 1 to 5 As shown, a number of universal wheels 8 are also installed at the bottom of the box body 2.

[0031] In the present invention, the universal wheel 8 is a prior art.

[0032] The provision of the universal wheels 8 facilitates the movement of the box 2 .

[0033] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is to include three solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution in which both A and B are satisfied. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0035] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
