The tool box comprises side walls arranged in the front-back direction or the left-right direction, that is, the front side wall 13, the rear side wall, the left side wall, the right side wall, and the bottom wall and the top wall connecting the above-mentioned side walls. The front side wall 13, the rear side wall, the left side wall, the right side wall and the bottom wall form a containing space for storing articles. In order to facilitate the description of the technical solution of the present application, the tool box is defined as a first type of tool box 10 and a second type of tool box 20, and of course the tool box system 100 is not limited to the above-mentioned two tool boxes, and there can be other tool boxes, and the relationship between any two tool boxes is described here. In addition, the first type of tool box 10 and the second type of tool box 20 can be the same type of tool box, or they can be different types of tool boxes, that is, they are not limited to the same tool box, but are not limited to the specific structure of the first type of tool box 10 and the second type of tool box 20, and they can be the same type of tool box. Of course, the tool box system 100 can also comprise a third type of tool box, or even a fourth type of tool box.

[0054] The pull rod device 22 is connected to the second type of tool box 20, and the pull rod device 22 has a pull rod for the user to hold. The structure of the pull rod device 22 can be the structure of a common pull rod on the market, which is not described in detail here. The pull rod is arranged on the rear side wall of the second type of tool box 20, which is convenient for the user to operate.

[0055] The walking device 21 is connected to the second type of tool box 20, and the walking device 21 comprises one or more wheels, and the walking device 21 can move the second type of tool box 20 relative to the ground. The wheels are generally arranged on the left and right side walls of the second type of tool box 20 and close to the rear side wall.

[0056] The connecting device 30 is used to couple the first type of tool box 10 and the second type of tool box 20, that is, the user can pull or push the wheels relative to the ground by holding the pull rod to rotate, thereby moving the first type of tool box 10 and the second type of tool box 20 together. It should be noted that the second type of tool box 20 can also be provided with a pull rod device 22 and a walking device 21, so that the first type of tool box 10 is directly stacked on the second type of tool box 20.

[0057] As Figures 2 to 9As shown, the connecting device 30 is used to couple the first tool box 10 to the upper end of the second tool box 20. The connecting device 30 comprises a first connecting piece 31, a second connecting piece 32, a first adapting piece 33, a second adapting piece 34 and an operating piece. The first connecting piece 31 cooperates with the first adapting piece 33, the second connecting piece 32 cooperates with the second adapting piece 34, and the operating piece can be driven by the user to move, during the movement of the operating piece, the first connecting piece 31 moves, during the movement of the first connecting piece 31, the first connecting piece 31 and the first adapting piece 33 are in a state of separation or contact. When the first connecting piece 31 and the first adapting piece 33 are separated, the first tool box 10 is configured to be removed from the second tool box 20. When the first connecting piece 31 and the first adapting piece 33 are in contact, the first tool box 10 is configured to be coupled with the second tool box 20.

[0058] That is, the tool box system 100 has at least two use states, which are defined as the first use state and the second use state. When the tool box system 100 is in the first use state, the first tool box 10 is connected with the second tool box 20, and the first tool box 10 can move together with the second tool box 20. When the tool box system 100 is in the second use state, the first tool box can be used separately from the second tool box 20. In this way, the user can select different use states according to the actual working conditions, which is convenient for the user to use. As a specific embodiment, the second tool box 20 can be provided with a walking device 21 and a pull rod device 22, so that the user can install the first tool box 10 on the second tool box 20, and then drive the second tool box 20 to move the first tool box 10 together. The third tool box can also be connected to the first tool box 10 through the connecting device 30. Of course, the second tool box 20 can also be provided without the walking device 21 and the pull rod device 22, so that the first tool box 10 is stacked on the second tool box 20. The above connecting device 30 connects two tool boxes, that is, the same structure can also be provided on the third tool box, so that the third tool box is connected to the first tool box 10 through the connecting device 30 or directly connected to the second tool box 20, thereby realizing the stacking of the tool boxes.

[0059] The state switching between the first use state and the second use state is realized by the connecting device 30. In the up-down direction, the height of the connecting device 30 is lower than the height of the upper cover 11 of the first tool box 10, so that when the user connects the two tool boxes, the connecting device 30 will not be damaged due to the current environment or the user's operation. The operating member in the connecting device 30 is used for the user to drive. During the driving of the operating member by the user, the first connecting member 31 can be moved together, so as to realize the separation or contact between the first connecting member 31 and the first adapting member 33, and then realize the state switching of the tool box system 100. The operating member is arranged on the side wall of the first tool box 10. In the up-down direction, the height of the operating member is lower than the height of the upper cover 11 of the first tool box 10, that is, the area for the user to drive the operating member is on the side wall of the first tool box 10. In order to save space and store more articles when transporting or storing the tool box, the user will put the tool boxes in multiple rows close to each other, which will result in a small operating space between each row of tool boxes. By arranging the operating member on the side wall, the user can drive the operating member in a narrow space, and the user can switch the state conveniently.

[0060] The first tool box 10 includes an upper cover 11 and a box body 12. The box body 12 forms a containing space for storing articles. The upper cover 11 is used to close the containing space. The box body 12 is formed by a front side wall 13, a rear side wall, a left side wall, a right side wall, and a bottom wall. The upper cover 11 can move relative to the box body 12, so that the user can open the upper cover 11 to place or store articles in the containing space. The operating member is arranged on the side wall formed by the box body 12. The height of the operating member is lower than the height of the upper cover 11, so that the user can use the operating member and the upper cover 11 conveniently without interference between them.

[0061] In this embodiment, the upper cover 11 is pivotally connected to the box body 12, that is, the upper cover 11 is connected to the box body 12 through a pivot shaft. The pivot shaft is arranged on the rear side wall of the box body 12, so that the user can rotate the upper cover 11 on the side of the front side wall 13 to unfold the containing space. The operating member is also arranged on the front side wall 13. In this way, the user can operate without moving the tool box when the user wants to open the upper cover 11 to take out or store articles, or wants to remove the tool box from another tool box. It should be noted that in some other embodiments, the upper cover can also be omitted.

[0062] The connecting device 30 comprises a first connecting piece 31, a second connecting piece 32, a first adapting piece 33, a second adapting piece 34 and an operating piece. The operating piece can be driven by a user to control the movement of the first connecting piece 31 by driving the operating piece. The first connecting piece 31 is connected to the first tool box 10, the second connecting piece 32 is connected to the first tool box 10, the first adapting piece 33 is connected to or formed on the second tool box 20, the second adapting piece 34 is connected to or formed on the second tool box 20, and the operating piece is arranged on the front side wall 13 of the first tool box 10. The first connecting piece 31 cooperates with the first adapting piece 33, and the second connecting piece 32 cooperates with the second adapting piece 34. The first connecting piece 31 is formed with a first connecting portion 311 capable of being coupled to the first adapting piece 33, and the second connecting piece 32 is formed with a second connecting portion 321 capable of being abutted against the second adapting piece 34 after the first connecting portion 311 is coupled to the first adapting piece 33.

[0063] As a feasible operation method, when the user wants to switch the tool box system 100 from the first use state to the second use state, the user drives the operating piece to move the first connecting piece 31 from the initial position to the preset position by a preset distance, the first connecting portion 311 is separated from the first adapting piece 33, the first tool box 10 is removed from the first tool box 10 after one end of the first tool box 10 is turned upward to a certain angle, at this time the second connecting portion 321 is separated from the second adapting piece 34, and at the same time the tool box system 100 is switched from the first use state to the second use state. It should be noted that the initial position refers to the position of the first connecting piece 31 when the operating piece is not affected by external force. The preset position is not a fixed position, as long as the position where the first connecting portion 311 can be separated from the first adapting piece 33 can be called the preset position, so the preset distance of movement is also determined according to the user's habit or the maximum distance that the first connecting piece 31 can move, which is not a fixed value.

[0064] When the user wants to switch the tool box system 100 from the second use state to the first use state, the user holds the first tool box 10 at a certain inclination angle, then contacts the second connecting portion 321 with the second adapting piece 34, and then turns the first tool box 10 downward until the first connecting portion 311 is coupled with the first adapting piece 33, at this time the first tool box 10 is coupled with the second tool box 20, and the tool box system 100 is switched from the second use state to the first use state.

[0065] As a specific embodiment, the connecting device 30 further comprises an elastic member 37 and a fixing member 38. In the embodiment, the first connecting member 31 and the operating member are formed as one part, and it can also be understood that the first connecting member 31 is formed with an operating portion 312 for being driven by a user.

The second connecting member 32 is integrally formed with the first tool box 10, and the second connecting member 32 is formed with a second connecting portion 321 abutting against the second tool box 20 only after the first connecting portion 311 is coupled with the first matching portion 331. The second connecting member 32 is formed with two second connecting portions 321, that is, the first tool box 10 is formed with two second connecting portions 321. The second matching member 34 is formed with two second matching portions 341 matched with the second connecting portions 321, and the second connecting portion 321 is specifically a clamping hook, and the second matching portion 341 is specifically a clamping groove.

[0067] In addition, the number of elastic members 37 is three, and the arrangement can make the first connecting member 31 move backward uniformly, avoid uneven force on the first connecting member 31 when moving, and avoid the situation that the first connecting member 31 and the first adapter 33 cannot be separated. That is, three first connecting columns 14 are arranged on the first tool box 10, and specifically, one first connecting column 14 is arranged at the rear end of the operating part 312, and the other two first connecting columns 14 are arranged at the rear end of the first connecting part 311.

[0068] The user switches the tool box system 100 from the first use state to the second use state, contacts and presses the operating part 312 backward, the first connecting member 31 moves backward by a preset distance to a preset position, at this time, the elastic member 37 is deformed under force, the first connecting part 311 is separated from the first adapter 331, at this time, the second connecting part 321 and the second adapter 341 are still in contact, then the user lifts one end of the first tool box 10 upward, that is, rotates one end of the front side wall 13 of the first tool box 10 upward, because the second connecting part 321 and the second adapter 341 are still in contact, at this time, the first tool box 10 is inclined relative to the second tool box 20, then the first tool box 10 is removed from the second tool box 20, that is, the second connecting part 321 and the second adapter 341 are separated, thereby realizing the switching of the tool box system 100 from the first use state to the second use state.

[0069] The user switches the tool box system 100 from the second use state to the first use state, the user holds the first tool box 10 to contact the second connecting part 321 and the second adapter 341, then rotates downward to contact the first connecting part 311 and the first adapter 331, continues to apply force to make the first connecting part 311 move backward and compress the elastic member 37, when the buckle is buckled into the buckle groove, the elastic member 37 restores deformation to make the first connecting part 311 and the first adapter 331 coupled.

[0070] Of course, after the second connecting part 321 and the second adapter 341 are abutted in place, the first tool box 10 is directly released, so that the first connecting part 311 and the first adapter 331 are directly buckled under the gravity of the first tool box 10, thereby coupling the first tool box 10 and the second tool box 20.

[0071] As Figures 10 to 11As shown, the connecting device 30 further comprises a holding assembly 40 for holding the first connecting member 31 in a state of separation from the first adapting member 33. The holding assembly 40 comprises a stopper 41 connected or formed on the second type of tool box 20, and the stopper 41 is capable of cooperating with the first connecting member 31, so that during the process of disengaging the first connecting portion 311 from the first adapting portion 331, the first connecting portion 311 is always held at a preset position. In this way, the user does not need to press the operating portion 312 all the time to keep the first connecting member 31 at the preset position, which is convenient for the user to use.

[0072] The holding assembly 40 is arranged at the lower end of the first connecting member 31, and the holding assembly 40 comprises the stopper 41, a biasing member 44, a movable member 42 and a sleeve 43. The stopper 41 is connected or integrally formed on the second type of tool box 20, and the biasing member 44 and the movable member 42 are connected to the first connecting member 31 through the sleeve 43. One end of the biasing member 44 abuts against the movable member 42, and the other end of the biasing member 44 abuts against the first connecting member 31. The sleeve 43 is provided with a through hole through which the movable member 42 is at least partially arranged, and the portion of the movable member 42 passing through the through hole is capable of cooperating with the stopper 41 during the process of switching the use state of the tool box system 100, so as to hold the first connecting member 31 at the preset position. The cover plate 36 is formed with a through hole through which the driving member is at least partially arranged, i.e. when the tool box system 100 is in the first use state, the stopper 41 partially passes through the cover plate 36. When the tool box system 100 is in the second use state, the stopper 41 is separated from the movable member 42. The movable member 42, the biasing member 44 and the sleeve 43 are connected to the first connecting member 31 and move together with the first connecting member 31.

[0073] Specifically, when the tool box system 100 is in the first use state, the first connecting piece 31 is in the preset position, and the stop piece 41 passes through the through hole on the cover plate 36. When the tool box system 100 is switched from the first use state to the second use state, the user drives the operation part 312 to move backward, i.e., the first connecting piece 31 moves backward. In the process of moving backward of the first connecting piece 31, the first connecting piece 31 drives the movable piece 42 to move a preset distance to the preset position. In the process of moving of the first connecting piece 31, the movable piece 42 approaches the stop piece 41 until contacting. Because the first connecting piece 31 continues to move backward, the movable piece 42 is forced to compress the biasing piece 44 to make the movable piece 42 pass over the stop piece 41. After the first connecting piece 31 moves to the preset position, the movement of the first connecting piece 31 stops. At this time, the user removes the force applied to the first connecting piece 31. At this time, the first connecting piece 31 moves forward under the action of the elastic piece 37 until the movable piece 42 abuts against the stop piece 41. The movement of the first connecting piece 31 stops and remains in the current position. At this time, the first connecting part 311 is separated from the first adapting part 331, and the second connecting part 321 is connected to the second adapting part 341. Then, the user holds the first type tool box 10 and turns one end of the first type tool box 10 upward. In the process of turning the first type tool box 10, the stop piece 41 is separated from the movable piece 42. At this time, the first connecting piece 31 loses the abutting force and continues to move forward until the initial position. As the turning angle of the first type tool box 10 is larger, the stop piece 41 gradually separates from the cover plate 36 until completely separating.

[0074] The biasing piece 44 is specifically a spring.

[0075] As other possible implementations, the stop piece can be connected to the first type tool box, and the movable piece can be connected to the second type tool box.

[0076] As Figures 12 to 21As another specific embodiment, the connecting device 50 further comprises a cover plate 56, an elastic member 57, a reset member 59 and a fixing member 58, as shown. In this embodiment, the operating member 55 and the first connecting member 51 are two separate parts. The operating member 55 can be driven by the user to move upward. During the upward movement of the operating member 55, the first connecting member 51 is forced to move backward to a preset position by a preset distance, and the first connecting part 511 is separated from the first adapting member 53. Then, the first tool box 10 is removed from the first tool box 10 after the first tool box 10 is turned upward to a certain angle. At this time, the second connecting part 521 is separated from the second adapting member 54, and the tool box system 100 is switched from the first use state to the second use state. When the user wants to switch the tool box system 100 from the second use state to the first use state, the user holds the first tool box 10 at a certain angle of inclination, and then contacts the second connecting part 521 with the second adapting member 54. Then, the first tool box 10 is turned downward until the first connecting part 511 is coupled with the first adapting member 53. At this time, the first tool box 10 is coupled with the second tool box 20, and the tool box system 100 is switched from the second use state to the first use state.

[0077] A plurality of first connecting columns 71 are formed on the front side wall 13 of the first tool box 10 and protrude forward. A plurality of clamping grooves are formed on the first connecting member 51 and match the first connecting columns 71. The clamping grooves can be partially sleeved on the outside of the first connecting columns 71. The elastic member 57 is arranged between the first tool box 10 and the first connecting member 51, that is, the elastic member 57 is sleeved on the first connecting columns. One end of the elastic member 57 abuts against the first tool box 10, and the other end of the elastic member 57 abuts against the first connecting member 51.

[0078] At least one second connecting column 72 is also formed on the front side wall 13 of the first tool box 10 and protrudes forward. At least one through hole corresponding to the second connecting column 72 is formed on the cover plate 56. The fixing member 58 passes through the through hole and connects with the second connecting column 72, so as to fixedly connect the cover plate 56 with the first tool box 10. A third connecting column 73 is also formed on the first tool box 10 and extends substantially downward. The reset member 59 is sleeved on the third connecting column 73. One end of the reset member 59 abuts against the first tool box 10, and the other end of the reset member 59 abuts against the operating member 55. A driving part 551 is formed on the operating member 55 and is used to drive the first connecting member 51 to move backward during the upward movement of the operating member 55. An opening is formed on the cover plate 56 and is used to allow an operating part 552 on the operating member 55 to protrude. The operating part 552 can be operated by the user to slide up and down in the opening. This arrangement facilitates the user to drive the operating part 552.

[0079] In the embodiment, in order to ensure the stability of the connection between the first tool box 10 and the second tool box 20, a plurality of first connecting portions 511 are arranged on the first connecting piece 51, and a plurality of first adapting portions 531 which are matched with the first connecting portions 511 are arranged on the first adapting piece 53. The number of the first connecting portions 511 is two, and the first connecting portions 511 are arranged at the two ends of the first connecting piece 51. The number of the first adapting portions 531 is also two, and the first adapting portions 531 are arranged at the two ends of the upper cover 11 of the second tool box 20. The first connecting portions 511 are specifically latches, and the first adapting portions 531 are specifically slots. Similarly, the second connecting piece 52 is integrally formed with the first tool box 10, that is, the second connecting piece 52 is formed with two second connecting portions 521. The second adapting piece 54 is formed with two second adapting portions 541 which are matched with the second connecting portions 521. The second connecting portions 521 are specifically latches, and the second adapting portions 541 are specifically slots.

[0080] In addition, the number of the elastic pieces 57 is two, and the arrangement can make the first connecting piece 51 move uniformly under force, so as to avoid the situation that the first connecting piece 51 and the first adapting piece 53 cannot be separated due to uneven force when the first connecting piece 51 moves. That is, the first tool box 10 is arranged with two first connecting columns 71, and specifically, the two first connecting columns 71 are arranged at the rear ends of the first connecting portions 511. Similarly, in order to ensure the smooth sliding of the operating piece 55 during the up and down sliding, the number of the reset pieces 59 is also two.

[0081] The moving direction of the contact portion 512 and the moving direction of the driving portion 551 form an angle, and specifically, the driving portion 551 is a slope formed on the operating piece 55. The first connecting piece 51 is formed with the contact portion 512 which is matched with the driving portion 551. The contact portion 512 is also a slope, and the driving portion 551 and the contact portion 512 always keep contact. The slope of the contact portion 512 and the slope of the driving portion 551 have basically the same inclination angle, but the inclination directions of the two are opposite. In this way, when the driving portion 551 moves upward, the contact portion 512 will move backward under force.

[0082] The user switches the toolbox system 100 from the first usage state to the second usage state. The user touches the operation part 552 and presses it upward. The reset member 59 deforms under force, and the contact part 512 on the first connector 51 moves backward a preset distance to a preset position under force. The elastic member 57 deforms under force, and the first connecting part 511 separates from the first adapter part 531. At this time, the second connecting part 521 and the second adapter part 541 are still in contact. Then, the user lifts one end of the first type of toolbox 10 upward, that is, rotates one end of the front side wall 13 of the first type of toolbox 10 upward. Since the second connecting part 521 and the second adapter part 541 are still in contact, the first type of toolbox 10 is tilted relative to the second type of toolbox 20. Then, the first type of toolbox 10 is removed from the second type of toolbox 20, that is, the second connecting part 521 and the second adapter part 541 are separated, thereby realizing the switching of the toolbox system 100 from the first usage state to the second usage state.

[0083] The user switches the toolbox system 100 from the second usage state to the first usage state. The user holds the first type of toolbox 10 and contacts the second connecting part 521 of the first type of toolbox 10 with the second adapter part 541. Then, the user can rotate it downwards to contact the first connecting part 511 with the first adapter part 531. The user continues to apply force to make the first connecting part 511 move backward and compress the elastic member 57. When the buckle is engaged in the slot, the elastic member 57 restores its deformation, so that the first connecting part 511 and the first adapter part 531 are coupled.

[0084] Of course, after the second connecting part 521 and the second adapter part 541 are in place, the first type of toolbox 10 is released directly. In this way, under the action of the gravity of the first type of toolbox 10, the first connecting part 511 and the first adapter part 531 are directly engaged. Thus, the first type of toolbox 10 and the second type of toolbox 20 are coupled.

[0085] Similarly, Figure 21 As shown, in this embodiment, the connecting device 50 also has a retaining component 60. The retaining component 60 in this embodiment is basically the same in structure and principle as the retaining component 60 in the previous embodiment, and will not be described again here. The difference is that the sleeve 61 is specifically installed at the lower end of the driving part 551.

[0086] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
