Description

Technical Field

[0001] This utility model belongs to the field of toolbox technology, specifically relating to an easily accessible engineering machinery toolbox. Background Technology

[0002] Construction machinery toolboxes are typically made of high-strength materials such as aluminum alloys and steel plates, which have good pressure and impact resistance. They can withstand the vibration and collisions during construction machinery operation and protect the tools inside from damage. To prevent rainwater, dust, and other contaminants from entering the toolbox and damaging the tools, toolboxes generally have good sealing properties and are equipped with rubber sealing rings, waterproof strips, etc., to ensure that the tools inside remain dry and clean even in harsh working environments.

[0003] In the field of engineering machinery maintenance, power tools are diverse and heavy, and usually require dedicated cases for centralized storage. Currently, most of these tool cases use traditional handle designs. When a large number of power tools are loaded inside, the overall weight increases significantly. Maintenance personnel rely solely on the handles for carrying, which not only consumes a lot of physical strength but also poses safety hazards such as tools scattering or the case falling during transport due to excessive weight. Therefore, it is very inconvenient for practical use. Utility Model Content

[0004] The purpose of this utility model is to provide an easily accessible toolbox for construction machinery, aiming to address the problem that in the field of construction machinery maintenance, power tools are diverse and heavy, typically requiring centralized storage in dedicated cases. In existing technologies, such toolboxes mostly employ traditional handle designs. When a large number of power tools are loaded inside, the overall weight increases significantly. Maintenance personnel relying solely on the handles not only expend considerable physical strength but also pose safety hazards such as tools scattering or the case falling during transport due to excessive weight, making it highly inconvenient for practical use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient engineering machinery toolbox, including a box body, a box cover installed at the open end of the box body, a handle installed on the surface of the box cover, two mounting parts symmetrically installed on one side of the box cover, and a pull rod rotatably installed between the two mounting parts;

[0006] A horizontal plate is installed on each of the two outer walls of the box. Two casters are symmetrically installed on the bottom of the horizontal plate. A screw is provided on the surface of the horizontal plate. The screw thread penetrates the interior of the mating part. One side of the mating part is installed on the outer wall of the box.

[0007] In order to ensure that the pull rod can be stably locked on the surface of the box cover when placed horizontally, as an easily accessible engineering machinery toolbox of this utility model, preferably, two sets of clips are symmetrically glued to the surface of the box cover, and a pad is provided on one side of the mounting component, with the bottom of the pad glued to the surface of the box cover.

[0008] When the pull rod is placed horizontally, it is interference-fitted inside the clamp; when the pull rod is placed at an angle, it is clamped inside the pad.

[0009] In order to enable the horizontal plate to move on the vertical bar with a stable trajectory, as a convenient engineering machinery toolbox of this utility model, preferably, two vertical bars are symmetrically installed on the outer walls of the two horizontal sides of the box body, and a sliding groove is opened on the outer wall of the side of the two vertical bars that are far apart.

[0010] A side plate is welded to each end of the horizontal plate, and a slider is welded to one side of each side plate. The two sliders are slidably connected to the inside of the corresponding grooves.

[0011] In order to enable the horizontal plate to quickly return to its original position after the downward pressure of the screw is released, as a convenient engineering machinery toolbox of this utility model, preferably, a connecting block is welded to the side of the horizontal plate facing the outer wall of the box, the bottom of the connecting block is welded to the top of the spring, the bottom of the spring is welded to the surface of the bottom block, and one side of the bottom block is welded to the outer wall of the box.

[0012] A positioning sleeve is welded to the outer wall of the connecting block and the horizontal plate connection end, and the inside of the positioning sleeve is movably inserted into the bottom of the screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the enclosure is filled with a large number of power tools used for the maintenance of construction machinery, the overall weight of the enclosure becomes quite significant, making it difficult for maintenance personnel to lift the entire enclosure using only the handles. In this situation, the following operations can be performed:

[0015] First, adjust the two screws downwards in sequence. As the screws move downwards, they will push the horizontal plate downwards through the threaded structure between them and the mating parts. As the horizontal plate moves downwards, it will push the casters downwards. Once the casters on both sides support the bottom of the box, rotate the pull rod towards one side of the pad through the mounting piece. When the pull rod is inserted into the pad, it can be tilted and positioned on the box cover. Maintenance personnel can then use the pull rod to move the box cover and the box, causing the two sets of casters at the bottom of the box to roll smoothly. This allows maintenance personnel to easily remove the box even when it is fully loaded. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides the following technical solution: an easy-to-access engineering machinery toolbox, including a box body 1, a box cover 2 installed at the open end of the box body 1, a handle 3 installed on the surface of the box cover 2, two mounting parts 4 symmetrically installed on one side of the box cover 2, and a pull rod 5 rotatably installed between the two mounting parts 4.

[0024] The entire box 1 is made of metal. The box 1 has a large storage space inside. When in use, maintenance personnel can place the electric drill, cutting machine and other tools needed for the maintenance of the construction machinery into the box 1 in sequence, and then put on the box cover 2 to take the box 1 to the construction machinery maintenance point for maintenance work.

[0025] A horizontal plate 6 is installed on each of the two outer walls of the box 1. Two universal wheels 7 are symmetrically installed at the bottom of the horizontal plate 6. A screw 8 is provided on the surface of the horizontal plate 6. The screw 8 is threaded through the interior of the connecting part 9. One side of the connecting part 9 is installed on the outer wall of the box 1.

[0026] Preferably, two sets of clips 21 are symmetrically bonded to the surface of the box cover 2, and a pad 22 is provided on one side of the mounting part 4, with the bottom of the pad 22 bonded to the surface of the box cover 2.

[0027] When the pull rod 5 is placed horizontally, it is interlocked inside the clamp 21; when the pull rod 5 is placed at an angle, it is interlocked inside the pad 22.

[0028] In actual use, when the pull rod 5 is placed horizontally, it will be inserted into the rubber clip 21, so that the pull rod 5 can be fixed inside the clip 21 to prevent the pull rod 5 from loosening.

[0029] Preferably, two longitudinal bars 11 are symmetrically installed on the outer walls of the two sides of the box body 1, and a groove 12 is opened on the outer wall of the side of the two longitudinal bars 11 that are far apart from each other;

[0030] A side plate 61 is welded to each end of the horizontal plate 6, and a slider 62 is welded to one side of the side plate 61. The two sliders 62 are slidably connected to the inside of the corresponding slide groove 12.

[0031] In actual use, when the screw 8 is adjusted upward, the pressure on the horizontal plate 6 will be gradually released. At this time, the spring 64 will reset. When the spring 64 resets, it will push the horizontal plate 6 upward. In this way, the horizontal plate 6 will drive the universal wheel 7 to move upward, so that the universal wheel 7 can be retracted upward when there is no need to pull it.

[0032] The bottom of the screw 8 has a semi-circular structure, and the semi-circular end of the bottom of the screw 8 is adapted to the inside of the positioning sleeve 66, so that the screw 8 will rotate very smoothly inside the positioning sleeve 66.

[0033] Preferably, a connecting block 63 is welded to one side of the horizontal plate 6 facing the outer wall of the box 1, the bottom of the connecting block 63 is welded to the top of the spring 64, the bottom of the spring 64 is welded to the surface of the bottom block 65, and one side of the bottom block 65 is welded to the outer wall of the box 1.

[0034] A positioning sleeve 66 is welded to the outer wall of the connecting end of the connecting block 63 and the horizontal plate 6. The inside of the positioning sleeve 66 is movably inserted into the bottom of the screw 8.

[0035] In practical use, when the box 1 is filled with a large number of power tools for maintenance of engineering machinery, resulting in a significant increase in overall weight, it becomes difficult to move them conveniently using only the handle 3. In this case, the following systematic operation can achieve easy relocation:

[0036] First, the screws 8 on both sides must be operated sequentially. The screws 8 engage with the mating parts 9 through threads, generating a vertical thrust during downward rotation. This thrust is transmitted to the horizontal plate 6 through a rigid connection structure, driving it to move smoothly downward along the guide rail. As the horizontal plate 6 descends, the casters 7 installed at its bottom gradually contact the ground, thus completing the support conversion.

[0037] After the casters 7 are supported, maintenance personnel can operate the pull rod 5. The pull rod 5 is rotatably connected to the cover 2 via the mounting piece 4. The operator needs to hold the pull rod 5 and apply force in a clockwise direction to rotate the pull rod 5 around the connecting end. When the pull rod 5 is rotated to align with the preset slot of the pad 22, a moderate downward pressing action is used to engage the locking protrusion at the end of the pull rod 5 into the groove of the pad 22.

[0038] At this time, maintenance personnel can hold the upper part of the pull rod 5, and under the action of horizontal traction, the caster 7 will move in the direction of the pulling force. In this way, maintenance personnel can easily move the fully loaded box 1 through this structure.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
