Description

Technical Field

[0001] This application relates to the field of toolboxes, and more particularly to a modular toolbox. Background Technology

[0002] Toolboxes are mainly used to store tools or accessories. Tools are categorized into different types during storage, so multiple toolboxes are used. During transportation, toolboxes need to be stacked together and secured to a trailer for manual towing. To prevent stacked toolboxes from falling, adjacent toolboxes need to be locked together by a locking mechanism. Based on an understanding of the relevant technologies, it was found that some stacked toolkits have cumbersome operation issues when locking and unlocking, resulting in a poor user experience. Summary of the Invention

[0003] The purpose of at least one specific embodiment of the present invention is to overcome the deficiencies of the prior art and provide a combined toolbox.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A combination toolbox, comprising: The box body has a grip opening and a locking opening on its side; A locking assembly, which is rotatably mounted on the housing; The actuating element has one end inserted into the grip opening and the other end in contact with the locking component; The elastic element has one end connected to the housing and the other end connected to the actuator, which is suitable for driving the actuator to reset. The box body is equipped with an insertion port that communicates with the locking port; When adjacent boxes are stacked, the locking component extends into the locking port through the insertion port on the adjacent box and locks with the locking port on the adjacent box, so that the stacked adjacent boxes are locked and fixed to each other. When a person applies a triggering action to the trigger, the locking assembly separates from the locking slot on the adjacent box, and the locking state between the stacked adjacent boxes is released.

[0005] Furthermore, the housing has an installation port, and the locking assembly is installed inside the installation port.

[0006] Furthermore, the locking assembly includes multiple locking claws rotatably mounted on the inner wall of the mounting port, a pin passing through the locking claws, and a torsion spring sleeved on the pin; The locking claw includes a locking part and a connecting part. The connecting part is hinged to the support part on the inner wall of the mounting port via a pin. One end of the torsion spring is connected to the connecting part, and the other end is connected to the pin. When the locking assembly is in its natural state, the torsion spring drives multiple locking claws to move toward the center of the mounting port.

[0007] Furthermore, the triggering element includes a triggering part and a squeezing part. The triggering part is located at the grip opening. One end of the elastic element is connected to the triggering part, and the other end is connected to the inner wall of the grip opening. The outer side of the squeezing part has a first inclined squeezing surface, and the inner wall of the locking claw has a second inclined squeezing surface corresponding to the first inclined squeezing surface.

[0008] Furthermore, the end of the locking part is provided with a third inclined pressing surface, and the top of the insertion port is provided with a fourth inclined pressing surface corresponding to the third inclined pressing surface. Before the adjacent boxes are stacked, the elastic element on the upper box is in a natural state, and the pressing part of the triggering element extends into the installation port and is inserted into the inner side of the locking assembly, so that each locking claw on the upper box expands radially. The diameter of the circumferential surface formed by the outer edge of the locking part of the multiple locking claws after expansion is larger than the diameter of the insertion port.

[0009] Furthermore, when adjacent boxes are stacked, the locking part of the locking claw extends into the top of the insertion port, and the third inclined pressing surface abuts against the fourth inclined pressing surface. Under the gravity of the upper box, a pressing force is formed between the third inclined pressing surface and the fourth inclined pressing surface, which causes the locking claw to retract toward the center of the insertion port. The second inclined extrusion surface on the inner side of the retracted locking claw applies extrusion force to the first inclined extrusion surface of the extrusion part. This extrusion force causes the extrusion part to move upward and compress the elastic element. After the third inclined pressing surface separates from the fourth inclined pressing surface, the locking part extends into the insertion port. At the same time, the elastic element drives the pressing part to reset until the locking part is located at the locking port. The reset pressing part applies a pressing force to the locking claw, so that the locking part of the locking claw is inserted into the locking port and locked.

[0010] Furthermore, when adjacent boxes are stacked, the touch part is lifted by hand, the touch part compresses the elastic element, the squeezing part moves upward, and the torsion spring drives multiple locking claws to move towards the center of the installation port, so that the diameter of the circumferential surface formed by the outer edge of the locking part of the multiple locking claws is smaller than the diameter of the insertion port, and the locking part of the multiple locking claws can extend into the insertion port. When the locking part extends into the insertion port and is located at the locking port, the person's hand is separated from the touching part, the elastic element drives the squeezing part to reset, and the reset squeezing part applies squeezing force to the locking claw, so that the locking part of the locking claw is inserted into the locking port and locked.

[0011] Furthermore, the diameter of the locking port is larger than the diameter of the insertion port.

[0012] Furthermore, the elastic element is a spring.

[0013] Furthermore, the bottom of the box is provided with a protruding support part, and the top of the box is provided with a recessed part. When two boxes are stacked, the support part at the bottom of the box matches the recessed part at the top of the adjacent box, and the bottom surface of the support part is flush with the end of the locking component or the trigger.

[0014] The advantages of the modular toolbox provided in this application compared to the prior art are as follows: When multiple boxes of the modular toolbox are stacked, after aligning the support parts and recesses of two adjacent boxes, the locking components installed on the boxes automatically lock with the locking ports on the adjacent boxes under their own weight. When two adjacent boxes need to be separated, a person can reach into the grip opening and pull the trigger upwards, and the locking components will automatically release the locking state between the locking ports on the adjacent boxes. At the same time, the pulling action can further separate the upper box from the lower box. The boxes of this modular toolbox can automatically lock with each other when stacked, and the locking state between adjacent boxes is automatically released when pulled, eliminating the locking action between two boxes and the locking state release action, making the operation convenient and quick.

Detailed Implementation

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0018] Reference Figures 1 to 4 A modular toolbox 100 includes a box body 10 with a grip opening 101 and a locking opening 102, a locking assembly 20 rotatably mounted on the box body 10, an actuating element 30 and an elastic element 40 mounted on the box body 10, wherein one end of the actuating element 30 extends into the grip opening 101 and the other end contacts and engages with the locking assembly 20, one end of the elastic element 40 is connected to the box body 10 and the other end is connected to the actuating element 30, and can drive the actuating element 30 to reset, wherein the elastic element 40 is preferably a spring.

[0019] Furthermore, the housing 10 is also provided with an insertion port 103 that communicates with the locking port 102. The diameter of the locking port 102 is larger than the diameter of the insertion port 103. When adjacent housings 10 are stacked, the locking component 20 extends into the locking port 102 through the insertion port 103 on the adjacent housing 10 and locks with the locking port 102 on the adjacent housing 10, so that the stacked adjacent housings 10 are locked and fixed to each other. When a person applies a tactile action to the trigger 30, the locking assembly 20 is separated from the locking port 102 on the adjacent box 10, and the locking state between the stacked adjacent boxes 10 is released.

[0020] Furthermore, the housing 10 has a mounting port 104, and the locking assembly 20 is installed in the mounting port 104. The locking assembly 20 includes a plurality of locking claws 201 rotatably mounted on the inner wall of the mounting port 104, a pin 202 passing through the locking claws 201, and a torsion spring 203 sleeved on the pin 202. Reference Figure 5The locking claw 201 includes a locking part 2011 and a connecting part 2012. The connecting part 2012 is hinged to the support part 204 on the inner wall of the mounting port 104 via a pin 202. One end of the torsion spring 203 is connected to the connecting part 2012 and the other end is connected to the pin 202. When the locking assembly 20 is in its natural state, the torsion spring 203 drives the multiple locking claws 201 to move toward the center of the mounting port 104.

[0021] Furthermore, refer to Figures 6 to 12 The actuating element 30 includes an actuating part 301 and a squeezing part 302. The actuating part 301 is located at the grip opening 101. One end of the elastic element 40 is connected to the actuating part 301, and the other end is connected to the inner wall of the grip opening 101. The outer side of the squeezing part 302 has a first inclined squeezing surface 303, and the inner wall of the locking claw 201 has a second inclined squeezing surface 205 corresponding to the first inclined squeezing surface 303.

[0022] Furthermore, the end of the locking part 2011 is provided with a third inclined pressing surface 2013, and the top of the insertion port 103 is provided with a fourth inclined pressing surface 105 corresponding to the third inclined pressing surface 2013. Before the adjacent boxes 10 are stacked, the elastic member 40 on the upper box 10 is in a natural state. The pressing part 302 of the trigger 30 extends into the mounting port 104 and is inserted into the inner side of the locking assembly 20, so that each locking claw 201 on the upper box 10 expands radially. The diameter of the circumferential surface formed by the outer edge of the locking part 2011 of the expanded multiple locking claws 201 is greater than the diameter of the insertion port 103.

[0023] In some embodiments, the bottom of the box 10 is provided with a protruding support portion 50, and the top of the box 10 is provided with a recessed portion 60. When two boxes 10 are stacked, the support portion 50 at the bottom of the box 10 matches the recessed portion 60 at the top of the adjacent box 10, and the bottom surface of the support portion 50 is flush with the end of the locking component 20 or the actuating component 30. When the box 10 is placed on the ground, the support portion 50 is supported on the ground, and the ends of the locking component 20 and the actuating component 30 on the side of the box 10 will not touch the ground. When two boxes 10 are stacked, the support portion 50 at the bottom of the box 10 matches the recessed portion 60 at the top of the adjacent box 10, which can play a positioning role for the two stacked boxes 10. After the support portion 50 and the recessed portion 60 are aligned, the locking component 20 on the upper box 10 is aligned with the insertion port 103 and the locking port 102 on the lower box 10, ensuring the accuracy of the locking fit between the two.

[0024] In addition, the top of the box 10 has a handle 70, which is designed to be rotatable and retractable. The recessed part 60 has a groove 80. When the handle 70 is not in use, it can be stored in the groove 80. When two adjacent boxes 10 are stacked, when a person is stacking them, they will habitually lift the box 10 by the handle 70 and place the lifted box 10 on top of the lower box 10. After the person releases the handle 70, the support part 50 of the upper box 10 matches the recessed part 60 of the lower box 10. At the same time, the weight of the upper box 10 can lock the two stacked boxes 10 together. At this time, the handle 70 in the groove 80 of the lower box 10 is covered by the upper box and will not be exposed.

[0025] In this embodiment, based on the special structural design of the toolbox, when the two boxes 10 are stacked, they can be automatically locked in two ways. The first way is to automatically lock the two boxes 10 after they are stacked, and the second way is to lock the two stacked boxes 10 after triggering the trigger 30. The specific operation methods will be described in detail below.

[0026] In this embodiment, the first method is to automatically lock the two boxes 10 after stacking: when adjacent boxes 10 are stacked, the support part 50 of the upper box matches the recessed part 60 of the lower box 10. After the support part 50 matches the recessed part 60, the upper box 10 and the lower box 10 will automatically align. The locking part 2011 of the locking claw 201 on the upper box 10 will automatically align and extend into the top of the insertion port 103 of the lower box 10. The third inclined pressing surface 2013 and the fourth inclined pressing surface 105 abut against each other. Under the gravity of the upper box 10, a pressing force is formed between the third inclined pressing surface 2013 and the fourth inclined pressing surface 105. This pressing force causes the locking claw 201 to retract toward the center of the insertion port 103. The second inclined extrusion surface 205 on the inner side of the retracted locking claw 201 applies extrusion force to the first inclined extrusion surface 303 of the extrusion part 302. This extrusion force causes the extrusion part 302 to move upward and compress the elastic member 40. The locking claw 201 extends further into the insertion port 103 until the third inclined pressing surface 2013 separates from the fourth inclined pressing surface 105. Then, the locking part 2011 extends into the insertion port 103. At the same time, the elastic member 40 drives the pressing part 302 to reset until the locking part 2011 is located at the locking port 102. The reset pressing part 302 applies a pressing force to the locking claw 201, so that the locking part of the locking claw 201 is inserted into the locking port 102 and locked.

[0027] This method mainly involves automatically locking the two boxes 10 when they are stacked. When the two boxes 10 are locked, there is no need to manually touch the locking component 20. Simply stack the upper box 10 on the lower box 10, and the upper box 10 will automatically lock the locking component 20 with the locking port 102 on the lower box 10 by its own weight. The locking operation is relatively convenient. Example 2

[0028] Reference Figures 13 to 16 Based on the same technical concept, in this embodiment, the top of the insertion port 103 does not need to be provided with a fourth inclined pressing surface 105. Compared with embodiment 1, the stacking of two boxes and locking in this embodiment belongs to the second locking method. The second locking method is that after triggering the actuator 30, the two stacked boxes 10 are locked: when adjacent boxes 10 are stacked, the support part 50 of the upper box matches the recessed part 60 of the lower box 10. After the support part 50 matches the recessed part 60, the locking assembly on the upper box 10 is engaged. When part 20 is automatically aligned with the insertion port 103 on the lower housing 10, the person pulls the trigger part 301, which compresses the elastic part 40. The squeezing part 302 moves upward, and the torsion spring 203 drives multiple locking claws 201 to move towards the center of the mounting port 104, so that the diameter of the circumferential surface formed by the outer edge of the locking part 2011 of the multiple locking claws 201 is smaller than the diameter of the insertion port 103. The locking part 2011 of the multiple locking claws 201 can smoothly extend into the insertion port 103 of the lower housing 10. When the locking part 2011 extends into the insertion port 103 and is located at the locking port 102, the hand is separated from the trigger part 301, the elastic member 40 drives the pressing part 302 to reset, and the reset pressing part 302 applies a pressing force to the locking claw 201, so that the locking part 2011 of the locking claw 201 is inserted into the locking port 102 and locked.

[0029] The second method mainly involves the user habitually reaching into the grip opening 101 and pulling the touch part 301 to lift the box 10. When the lifted box 10 is stacked on top of another box 10, the upper box 10 can automatically lock the locking component 20 to the locking port 102 on the lower box 10 by its own weight.

[0030] Therefore, when multiple boxes of this modular toolbox are stacked, after aligning the support portion 50 and recessed portion 60 of two adjacent boxes 10, the locking component 20 installed on the box 10 automatically locks with the locking port 102 on the adjacent box under its own weight. When two adjacent boxes 10 need to be separated, a person can reach into the grip opening 101 and pull the trigger 30 upwards. The locking component 20 and the locking port 102 on the adjacent box will automatically release. At the same time, the pulling action can further separate the upper box 10 from the lower box. When the boxes of this modular toolbox are stacked, they can automatically lock with each other. When pulled, the locking state between adjacent boxes is automatically released, eliminating the locking action and locking release action between two boxes 10. The operation is convenient and quick.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
