[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a maintenance box that is easy to carry, including a maintenance box body, both side surfaces of the maintenance box body are fixedly connected with an upper side plate and a lower side plate, and the surfaces of the upper side plate and the lower side plate are respectively rotatably connected with a screw rod and fixedly connected with a track column, a movable empty slot is opened in the upper side plate, and a gear is rotatably connected in the movable empty slot, the rotating shaft on the gear is fixedly connected with the screw rod, the surfaces of the screw rod and the track column are provided with connecting plates, and the connecting plates penetrate the track column and are threadedly connected with the screw rod, both ends of the connecting plates are fixedly connected with rollers, a pull plate is inserted in the upper side plate, and teeth are fixed on the surface of the pull plate, the teeth are meshed with the gear, a push rod is fixed on the surface of the pull plate, mounting plates are fixed on both sides of the maintenance box body, and bolts are threadedly connected to the mounting plates and the pull plates.

[0006] As a preferred embodiment, a partition is slidably connected inside the maintenance box body.

[0007] As a preferred implementation, a space dividing plate is fixedly connected to the upper surface of the partition.

[0008] As a preferred embodiment, a socket opening is provided on one side of the maintenance box body.

[0009] As a preferred embodiment, the lower side plate is slidably connected with a sliding block near one end thereof, and one end of the sliding block is snap-connected with a side surface of the roller.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model draws out the pull plate to move the teeth to drive the gear and the screw to rotate, so that the connecting plate and the roller are moved down along the track column relative to the maintenance box body, so that the maintenance box body is propped up and suspended in the air as a whole. With the help of the roller, the maintenance box body can be moved conveniently. The pull plate is installed on the mounting plate by bolts, so that the maintenance personnel can control the overall movement of the maintenance box body by pushing the push rod when walking, which is more labor-saving and solves the problem that the maintenance box body is inconvenient to carry when it is heavy.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a maintenance box that is easy to carry, including a maintenance box body 1, both side surfaces of the maintenance box body 1 are fixedly connected with an upper side plate 2 and a lower side plate 3, and the surfaces of the upper side plate 2 and the lower side plate 3 are respectively rotatably connected with a screw rod 4 and a track column 6 fixedly connected, by rotating the screw rod 4, the connecting plate 7 and the roller 8 can be controlled to move downward along the track column 6 relative to the maintenance box body 1, a movable empty slot is opened in the upper side plate 2, and a gear 5 is rotatably connected in the movable empty slot, the rotating shaft on the gear 5 is fixedly connected to the screw rod 4, by pulling out the pull plate 9, the teeth 10 are moved to drive the gear 5 to rotate, thereby facilitating the control of the rotational movement of the screw rod 4, the surfaces of the screw rod 4 and the track column 6 are provided with a connecting plate 7, and the connecting plate 7 and the track column 6 are penetrated and threadedly connected to the screw rod 4, and the two ends of the connecting plate 7 are fixedly connected with rollers 8, by allowing the connecting plate 7 and the roller 8 moves downward along the track column 6 relative to the maintenance box body 1, so that the maintenance box body 1 is propped up and suspended as a whole, and the maintenance box body 1 is convenient to move with the help of the roller 8. A pull plate 9 is inserted and connected in the upper side plate 2. When the maintenance box body 1 is not normally stored, the pull plate 9 is retracted into the upper side plate 2 to reduce the overall space occupied by the device. At the same time, the retraction and extension of the pull plate 9 will also allow the roller 8 to be retracted upward relative to the maintenance box body 1 to ensure the stability of the device during storage. A tooth 10 is fixed on the surface of the pull plate 9, and the tooth 10 is meshed with the gear 5. A push rod 11 is fixed on the surface of the pull plate 9. Mounting plates 12 are fixed on both sides of the maintenance box body 1, and bolts 13 are threadedly connected to the mounting plate 12 and the pull plate 9. The pull plate 9 is installed on the mounting plate 12 by the bolts 13, which is convenient for maintenance personnel to control the overall movement of the maintenance box body 1 by pushing the push rod 11 when walking, which is more labor-saving.

[0021] Example 2

[0022] like Figure 1-4As shown, a partition 14 is slidably connected inside the maintenance box body 1. Some of the maintenance tools carried in the maintenance box body 1 require electricity. In order to facilitate the use of tools, a mobile power supply is carried in the maintenance box body 1, and the partition 14 separates the tools and the mobile power supply in the maintenance box body 1, which plays a certain protective role for the mobile power supply. A space dividing plate 15 is fixedly connected to the upper surface of the partition 14. The space dividing plate 15 separates different types of tools for storage to avoid messy storage of tools and difficulty in finding them. A socket opening 16 is provided on one side of the maintenance box body 1. Through the setting of the socket opening 16, the mobile power supply does not need to be taken out of the maintenance box body 1 when it needs to be used. The tool plug can be directly connected to the mobile power supply through the socket opening 16. A sliding block 17 is slidably connected to the lower side plate 3 near one end thereof, and one end of the sliding block 17 is engaged with one side of the roller 8. Through the connection between the sliding block 17 and the roller 8, the stability of the roller 8 on one side relative to the maintenance box body 1 after being lowered is improved, thereby further ensuring the stability of the maintenance box body 1 during the pushing process.

[0023] Working principle:

[0024] like Figure 1-4 As shown, when the utility model is in use, the user first puts the mobile power supply into the interior of the maintenance box body 1, then places the partition 14 into the interior of the maintenance box body 1, and puts the tools needed for maintenance in the space separated by the space dividing plate 15, then closes the maintenance box body 1, and then pulls the push rod 11 to pull the pull plate 9 out of the upper side plate 2, so that the teeth 10 move to drive the gear 5 and the screw 4 to rotate, so that the connecting plate 7 and the roller 8 as a whole move downward along the track column 6 relative to the maintenance box body 1, so that the maintenance box body 1 is propped up and suspended as a whole, and then pushes the sliding block 17 to connect it to one side of the roller 8, and then installs the pulled out pull plate 9 on the mounting plate 12 through the bolt 13 to complete the assembly, so that the maintenance personnel can control the overall movement of the maintenance box body 1 by pushing the push rod 11 when walking, which is more labor-saving.
