DETAILED DESCRIPTION

[0029] For better understanding and implementation, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application.

[0030] In the description of the present application, it should be noted that the directions or position relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the present application in that the indicated devices or elements must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0032] Referring to Figure 1 and Figure 2 , the present application discloses a tool bag convenient to transport, which comprises a shell 10, a rolling member 30 and a rotating assembly. Specifically, the shell 10 is provided with a mounting surface 11, the mounting surface 11 is provided with a receiving groove 12, and the receiving groove 12 is provided with a locking structure. Referring to Figure 2 , the rolling member 30 is rotatably mounted on the shell 10 through the rotating assembly, and the rolling member 30 is used to approach or move away from the receiving groove 12 when the rotating assembly rotates, wherein the rolling member 30 is used to be received in the receiving groove 12 after approaching the receiving groove 12, and to be in a receiving state after the rotating assembly abuts against the locking structure. Referring to Figure 5 , the rolling member 30 is used to protrude out of the shell 10 after moving away from the receiving groove 12, and to be in a use state after the rotating assembly separates from the locking structure.

[0033] On the basis of this structure, when the tool bag of the present application is used, in the initial state, the rolling member 30 is received in the receiving groove 12 of the shell 10, the rotating assembly abuts against the locking structure, and the tool bag is in a compact receiving mode convenient for carrying and storing, for example, when stored in a warehouse, placed in a trunk or carried by hand or worn on the back, this receiving state can effectively save space and avoid the rolling member 30 protruding to cause bumping or obstruction.

[0034] When it is needed to use the tool bag for mobile transportation, such as long distance transfer of tools on flat road outside, the rotating assembly can be separated from the locking structure to be unlocked. After unlocking, the rotating assembly is rotated outwardly together with the rolling member 30 by manually pulling the rolling member 30 or rotating the rotating assembly, so that the rolling member 30 gradually moves away from the storage slot 12 until the rolling member 30 is completely extended out of the shell 10, and the tool bag is switched to the use state, at which time the rolling member 30 can be used for convenient rolling transportation.

[0035] When it is needed to store the rolling member 30 again, the rolling member 30 can be manually rotated towards the storage slot 12, and after the rolling member 30 is completely stored in the storage slot 12, the rotating assembly is again abutted with the locking structure to be locked, so that the tool bag returns to the initial compact storage state, facilitating subsequent storage and carrying.

[0036] Thus, the tool bag is provided with the rotating assembly to realize folding of the rolling member 30, so that the rolling member 30 can be in the storage state of being stored in the storage slot 12 or the use state of being extended out of the shell 10 during rotation of the rotating assembly. In the storage state, the rolling member 30 is avoided from being a burden when being worn on the back or being damaged due to terrain. In the use state, the rolling member 30 can roll on flat road to reduce the transportation burden of the user. Therefore, the adaptability of the tool bag to different terrains and the convenience of transportation are improved.

[0037] It should be noted that the tool bag is further provided with the locking structure arranged in the storage slot 12 to lock the rotating assembly, so as to limit rotation of the rotating assembly together with the rolling member 30, and the rolling member 30 is kept in the storage state, which effectively prevents the rolling member 30 from accidentally popping out during transportation or storage. Meanwhile, the rolling member 30 is connected to the shell 10 through the rotating assembly to realize detachable connection of the rolling member 30 and the shell 10, which avoids problems such as inconvenient maintenance and disassembly caused by traditional fixed connection.

[0038] Further, referring to Figure 3 , the rotating assembly comprises a rotating arm 21 and a connecting shaft 20. Specifically, one end of the rotating arm 21 is provided with a sleeve 22, referring to Figure 4 , the connecting shaft 20 is arranged in the storage slot 12, and the sleeve 22 is rotatably sleeved on the outer periphery of the connecting shaft 20, wherein the other end of the rotating arm 21 is connected with the rolling member 30.

[0039] On the basis of the structure, when the rolling member 30 is stored in the storage slot 12 during use, the sleeve 22 is sleeved on the outer periphery of the connecting shaft 20, and the rotating assembly as a whole is locked by abutting with the locking structure. One end of the rotating arm 21 can stably rotate on the connecting shaft 20 through the sleeve 22, but the rotation is limited by the locking structure to ensure that the rolling member 30 will not be accidentally extended out of the storage slot 12.

[0040] When the locking structure needs to be unlocked, the rotating assembly can be separated from the locking structure. Then the rolling member 30 is manually pulled or pushed, and the rolling member 30 drives the rotating arm 21 connected thereto to rotate around the connecting shaft 20. Since the sleeve 22 is rotatably sleeved on the outer periphery of the connecting shaft 20, the rotating arm 21 can rotate outward relative to the connecting shaft 20.

[0041] Therefore, the rotating arm 21 stably supports the rolling member 30 extending out of the shell 10 through the cooperation of the sleeve 22 and the connecting shaft 20, and the rolling member 30 can roll on the ground to realize convenient transportation of the tool bag. At this time, the connection between the rotating arm 21 and the connecting shaft 20 ensures that the rolling member 30 can withstand a certain pressure and impact force during rolling.

[0042] In addition, the rotating assembly adopts the structure of the sleeve 22 and the connecting shaft 20 to realize detachable connection of the rolling member 30 and the shell 10. When the rolling member 30 or the rotating assembly is damaged, the rotating arm 21 can be conveniently detached from the connecting shaft 20 for separate maintenance or replacement, avoiding the difficulty of maintenance and disassembly caused by the traditional fixed connection mode.

[0043] Further, referring to Figure 3 The rolling member 30 comprises a rolling wheel 31 and a rotating shaft 32, wherein the rotating shaft 32 is connected to the other end of the rotating arm 21, and the rolling wheel 31 rotates around the rotating shaft 32.

[0044] In the use state, the rolling wheel 31 is in contact with the ground, and the rolling wheel 31 converts the sliding friction between the tool bag and the ground into rolling friction by rotating around the rotating shaft 32, greatly reducing the friction during transportation, making the transportation of the tool bag on the flat road more easy and convenient.

[0045] The rotating shaft 32 serves as the support shaft of the rolling wheel 31 and provides a stable rotation center for the rolling wheel 31. In addition, the connection of the rotating shaft 32 and the rotating arm 21 enables the rolling member 30 to be retracted and extended under the driving of the rotating arm 21, and cooperates with the locking structure and the rotating assembly to realize the switching of the tool bag in different states.

[0046] Further, the rotating assembly further comprises a torsional spring 23, specifically, the main body of the torsional spring 23 is sleeved on the outer periphery of the connecting shaft 20 and located in the sleeve 22, and the two ends of the torsional spring 23 respectively abut against the retraction groove 12 and the bottom of the sleeve 22.

[0047] On the basis of this structure, the main body of the torsional spring 23 extends along the axial direction of the connecting shaft 20, and the two ends of the torsional spring 23 are respectively a fixed end 231 and a movable end 232, wherein the fixed end 231 abuts against the retraction groove 12, and the movable end 232 abuts against the bottom of the sleeve 22.

[0048] When it is needed to store the rolling member 30, an external force can be applied to the rotating arm 21, so that one end of the rotating arm 21 rotates around the connecting shaft 20 through the sleeve 22, the other end of the rotating arm 21 drives the rolling member 30 to approach the storage groove 12, and then the rotating assembly is locked by abutting against the locking structure. In this process, the sleeve 22 drives the movable end 232 of the torsional spring 23 to approach the fixed end 231 of the torsional spring 23, so that the torsional spring 23 is in a compressed state in the circumferential direction, and the elastic potential energy is stored.

[0049] When it is needed to use the rolling member 30 for transportation, the rotating assembly is first separated from the locking structure to achieve unlocking. After unlocking, the movable end 232 of the torsional spring 23 automatically moves away from the fixed end 231, the stored elastic potential energy is released, and the sleeve 22 rotates under the action of the torsional spring 23, thereby driving the rotating arm 21 and the rolling member 30 to pop out towards the outside away from the mounting groove.

[0050] Therefore, by arranging the torsional spring 23, the rolling member 30 can be more easily stretched out of the storage groove 12, and the operation burden of the user is reduced. At the same time, in the use state, the rolling member 30 is completely stretched out of the shell 10, and the pre-tightening force of the torsional spring 23 will generate a certain force on the rotating arm 21 and the sleeve 22, preventing the sleeve 22 from rotating under the action of no external force, and ensuring that the rolling member 30 and the rotating arm 21 are in a stable position. In this way, it can prevent the rolling member 30 from shaking, deviating and other unstable conditions during use.

[0051] Further, referring to Figure 2 , the locking structure includes a raised step 13, and the raised step 13 is arranged on one side of the storage groove 12 close to the mounting surface 11. The raised step 13 is used to abut against one side of the rotating arm 21 when the rolling member 30 is stored in the storage groove 12, so that the rotating arm 21 compresses the torsional spring 23.

[0052] On the basis of this structure, when it is needed to store the rolling member 30 in the storage groove 12, an external force can be applied to the rotating arm 21, so that one end of the rotating arm 21 rotates around the connecting shaft 20 through the sleeve 22, and the other end of the rotating arm 21 drives the rolling member 30 to approach the storage groove 12. When the rotating arm 21 is rotated in place, the bottom end of the rotating arm 21 is pressed downwards to abut against the inner side of the raised step 13, and at this time the rotating arm 21 is pressed against the raised step 13 under the action of the torsional spring 23, thereby achieving locking.

[0053] Therefore, by abutting and locking the raised step 13 and the rotating arm 21, it can prevent the rolling member 30 from accidentally popping out, and ensure the stability of the entire tool kit in the storage state. Whether the tool kit is jolted during transportation or is squeezed by external force during storage, the storage state of the rolling member 30 can be maintained, and the rolling member 30 can be prevented from being damaged.

[0054] Further, the bottom of the rotating assembly is provided with a button 24. Specifically, the button 24 can abut against the outside of the sleeve 22 and is used to drive the rotating assembly to separate from the locking structure under the action of external force.

[0055] On the basis of the structure, when the roller 30 needs to be used, an external force can be applied to press the button 24. Since the button 24 abuts against the sleeve 22, the button 24 can lift the sleeve 22, so that the sleeve 22 drives the rotating arm 21 to separate from the locking structure, thereby achieving unlocking. At this time, one end of the rotating arm 21 can rotate relative to the connecting shaft 20 through the sleeve 22, thereby driving the roller 30 at the other end to rotate away from the mounting groove to present a use state.

[0056] Therefore, the unlocking is achieved by the pressing action of the button 24, and the conversion process from the storage state to the use state is simplified. In the case of urgently needing to carry the tool, the operator can complete the unlocking action in an instant and quickly push the tool bag to move, thereby greatly improving the work efficiency.

[0057] Further, the button 24 is also sleeved on the connecting shaft 20. One end of the button 24 is arranged in the storage groove 12, and the other end of the button 24 is located outside the storage groove 12.

[0058] On the basis of the structure, the button 24 is in a columnar shape and has a connecting section 241, an abutting section 242 and a pressing section 243 in sequence along the axial direction of the columnar body. The connecting section 241 is sleeved on the connecting shaft 20. The outer diameter of the abutting section 242 is greater than that of the connecting section 241, and the upper end of the abutting section 242 abuts against the bottom of the sleeve 22. Referring to Figure 2 and Figure 4 The storage groove 12 is also provided with a mounting hole 121. The pressing section 243 of the button 24 extends out of the storage groove 12 through the mounting hole 121 and is located at the bottom of the tool bag. The pressing section 243 is slidingly connected in the mounting hole 121.

[0059] When the rotating assembly is unlocked, the pressing section 243 at the bottom of the tool bag can be pressed. The pressing section 243 drives the abutting section 242 to move upward, the abutting section 242 presses the sleeve 22 upward, the sleeve 22 drives the rotating arm 21 to move upward away from the abutment of the protruding step 13 under the action of the button 24, and then the rotating arm 21 and the roller 30 are driven by the torsional spring 23 to pop out of the storage groove 12.

[0060] When the button 24 is pressed, the connecting section 241 slides on the connecting shaft 20. The connecting shaft 20 guides the up-and-down movement of the button 24, thereby avoiding the button 24 from being stuck during the pressing process.

[0061] Therefore, only the button 24 at the bottom of the tool bag needs to be pressed to separate the rotating assembly from the locking structure, and then the roller 30 can be switched to the use state for use.

[0062] Further, the shell 10 comprises a base 14 and a main body bag 15, and the main body bag 15 is connected to the base 14; refer to Figure 4 The mounting surface 11 is formed on the side of the base 14 away from the main body bag 15. Among them, the base 14 is provided with a lifting pull rod 16, and the bottom of the lifting pull rod 16 is provided with a sliding plate, and the base 14 is also provided with a sliding groove, and the two sides of the sliding plate are respectively connected to the sliding groove.

[0063] On the basis of this structure, when the tool bag is in the initial storage state, the rolling member 30 is stored in the storage groove 12, the lifting pull rod 16 is in the lowest position, and the sliding plate is at the bottom of the sliding groove in the base 14. If you want to start using the tool bag for transportation, you first need to convert the rolling member 30 from the storage state to the use state. Then operate the lifting pull rod 16 and pull it up. With the pulling action, the sliding plate at the bottom of the lifting pull rod 16 slides upward in the sliding groove until it reaches the appropriate height to easily push the tool bag forward.

[0064] Therefore, the height of the lifting pull rod 16 can be adjusted, and the rolling member 30 is rolled by the lifting pull rod 16 to transport the tool bag. Among them, the two sides of the sliding plate are tightly matched with the sliding groove, which ensures the stability of the lifting pull rod 16 during the lifting process.

[0065] Further, refer to Figure 1 and Figure 2 The mounting surface 11 is also provided with two first clamping grooves 17, and correspondingly, the two sides of the base 14 are provided with second clamping grooves 18. In addition, the tool bag also comprises a shoulder strap 19, and the two ends of the shoulder strap 19 are respectively provided with elastic buckles 191, and the two ends of the shoulder strap 19 are respectively connected with the first clamping groove 17 and the second clamping groove 18 through the elastic buckles 191.

[0066] On the basis of this structure, when the tool bag needs to be used in the storage state, the rolling member 30 can be stored in the storage groove 12, and the shoulder strap 19 is buckled with the first clamping groove 17 and the second clamping groove 18. At this time, the user can put his arms through the two shoulder straps 19, and the mounting surface 11 is attached to the back of the body, so as to carry the tool bag on the body.

[0067] Because the rolling member 30 is stored in the storage groove 12, when the tool bag is carried, it will not be affected by the protruding rolling member 30, ensuring the comfort of the user when carrying. At the same time, the detachable connection of the shoulder strap 19 and the tool bag makes it possible to detach the shoulder strap 19 when the tool bag is transported by rolling the rolling member 30, refer to Figure 5 At this time, the shoulder strap 19 will not affect the transportation of the tool bag.

[0068] Further, refer to Figure 2The outer periphery of the main bag 15 is provided with a corrugated structure 151, so that the main bag 15 can be folded.

[0069] On the basis of the structure, when the main bag 15 needs to be folded, force can be applied to the outer side of the main bag 15 to fold the main bag 15 along the corrugated structure 151 and gradually compress it to a minimum volume state. Then manually rotate the rotating arm 21 to store the rolling member 30 back into the storage groove 12, and make the rotating arm 21 abut against the locking structure to realize locking. At this time, the tool bag reduces the occupied space, and is convenient to carry and store.

[0070] When the folded main bag 15 needs to be unfolded, the two sides of the main bag 15 can be held with both hands, and stretched outward along the folding direction of the corrugated structure 151. With the stretching action, the corrugated structure 151 gradually unfolds, and the capacity of the main bag 15 expands, which is convenient for loading more tools.

[0071] Therefore, the corrugated structure 151 enables the main bag 15 to be tightly folded when stored. When storing the tool bag, whether it is placed vertically on the shelf or horizontally in the vehicle trunk, the folded main bag 15 does not occupy too much additional space.

[0072] In addition, when the tool bag is extruded or collided by external force, the corrugated structure 151 can disperse and absorb part of the impact force through its own deformation, so as to protect the tools in the main bag 15 from being damaged.

[0073] The technical means disclosed by the utility model scheme is not only limited to the technical means disclosed by the above-mentioned embodiments, but also includes the technical scheme composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the utility model, some improvements and refinements can be made, and these improvements and refinements are also considered within the protection scope of the utility model.
