[0026] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0027] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0029] An embodiment of this utility model provides a modular handcart with a handle, such as... Figure 1-2 As shown, the vehicle includes a first vehicle body, a second vehicle body, and a handle. Both the first and second vehicle bodies include a base plate 310 and multiple casters 320 located at the bottom of the base plate 310. The casters 320 are rotatable to reduce friction and facilitate pulling the entire vehicle body. The casters 320 can be either directional casters or swivel casters. The base plates 310 of the first and second vehicle bodies are detachably combined, allowing them to separate and form two independent vehicle bodies. Users can use both vehicle bodies independently. Alternatively, the base plates 310 of the first and second vehicle bodies can be combined to form a combined vehicle body, which increases the area of ​​the base plate 310, allowing for the placement of larger goods.

[0030] The handle includes two pull rods 200, two connecting seats 100, and a gripping rod 210 for the user to hold. The user can grasp the gripping rod 210 and pull the entire handle. The upper ends of both pull rods 200 are connected to the gripping rod 210, and the lower ends of both pull rods 200 are connected to the two connecting seats 100 respectively. The two connecting seats 100 are detachably connected to the bottom plates 310 of the first and second vehicle bodies, respectively. When the two connecting seats 100 are connected to the bottom plates 310 of the first and second vehicle bodies, the user can pull the gripping rod 210 to move the two combined vehicle bodies, making it convenient for the user to pull the vehicle bodies. When the two connecting seats 100 are detached from the bottom plates 310 of the first and second vehicle bodies, the first and second vehicle bodies can be used together or separately. This creates multiple usage modes, making it more flexible and convenient for the user.

[0031] In some embodiments, as Figure 1-6 As shown, the top surfaces of the first vehicle body's base plate 310 and the second vehicle body's base plate 310 are both provided with mounting holes 311 extending through to their bottom surfaces. The mounting holes 311 are adapted to the connecting seat 100, which can pass through the mounting holes 311. The connecting seat 100 has receiving grooves 101 on its two opposite sides. The two receiving grooves 101 can be connected to each other or independent of each other. Each of the two receiving grooves 101 is provided with a locking member 110 and an elastic member 120. The locking members 110 in both receiving grooves 101 can slide in a direction parallel to each other, thus allowing them to move closer or further apart. As the locking member 110 slides relative to the connecting seat 100, it can slide to a locked state where at least part of it extends out of the receiving groove 101, and to an unlocked state where it retracts into the receiving groove 101. When the locking member 110 is in the locked state, since it extends at least partially beyond the receiving groove 101, the protruding part bulges out from the side of the connecting seat 100, thus serving as a limit. When the locking member 110 is in the unlocked state, since it retracts into the receiving groove 101, it no longer serves as a limit.

[0032] One end of the elastic member 120 abuts against the locking member 110, and the other end can abut against the inner wall of the receiving groove 101 or other stops inside the receiving groove 101. The elastic member 120 can apply an elastic force to the locking member 110. Under the elastic force of the elastic member 120, the locking member 110 remains locked, at least partially extending out of the receiving groove 101. After the connecting seat 100 is fixed to the bottom plate 310 of the vehicle body, the force of the elastic member 120 can keep the connecting seat 100 connected to the bottom plate 310. Without external force, the connecting seat 100 is difficult to detach from the bottom plate 310, thus improving the stability of the connection. The locking member 110 is also connected to a pressing plate 130. The pressing plate 130 extends from the bottom surface of the connecting seat 100 and can slide relative to the connecting seat 100 with the locking member 110. Thus, the user can press the pressing plate 130, thereby causing the locking member 110 to slide to switch the state of the locking member 110.

[0033] When installing the handle of this embodiment, the user can press the pressing plate 130, causing the locking member 110 to overcome the force of the elastic member 120 and switch the locking member 110 to the unlocked state, so as not to block the connector 100 from being inserted into the mounting hole. Then, the connector 100 is passed through the mounting hole 311, and then the pressing plate 130 is released. Under the action of the elastic member 120, the locking member 110 remains locked. The outwardly protruding locking member 110 can abut against the bottom surface of the base plate 310 to prevent the connector 100 from disengaging from the mounting hole 311, thereby fixing the handle to the base plate 310 of the vehicle body. When disassembling the handle of this embodiment, the user can press the pressing plate 130, causing the locking member 110 to overcome the force of the elastic member 120 and switch the locking member 110 to the unlocked state. The retracted locking member 110 no longer restricts the connector 100. Then, the connector 100 is pulled out from the mounting hole 311, and the handle can be separated from the vehicle body, completing the disassembly.

[0034] In some embodiments, the bottom of the outer ends of the two locking members 110 that are far apart from each other are provided with guide ramps 111, and the height of the guide ramps 111 gradually increases in the direction in which the two locking members 110 are far apart from each other. During the process of inserting the connecting seat 110 into the mounting hole 311, the side edge of the top opening of the mounting hole 311 abuts against the guide ramps 111. Due to the inclined structure of the guide ramps 111, under the action of the pressing force, the locking member 110 will retract inward, thereby reaching the unlocked state retracted into the receiving groove 101, allowing the user to smoothly pass the connecting seat 110 through the mounting hole 311. Therefore, in this embodiment, when installing the handle, it is not necessary to manually press the pressing plate 130. After being subjected to the pressing force, the locking member 110 can automatically retract to the unlocked state, saving the user the operation of pressing the pressing plate 130, making the installation of the handle more convenient.

[0035] In some embodiments, the locking member 110 is provided with a guide groove 112, the extension direction of the guide groove 112 is parallel to the sliding direction of the locking member 110 relative to the connecting seat 100, and a guide post 140 is provided in the receiving groove 101. The guide post 140 is inserted into the guide groove 112 and can slide in the guide groove 112. The cooperation between the guide post 140 and the guide groove 112 guides the sliding direction of the locking member 110, so that the locking member 110 slides stably along a direction parallel to each other and close to each other, avoiding the problem of being unusable due to the deviation of the sliding direction.

[0036] In some embodiments, a protruding limiting ring 150 is provided at the upper end of the outer peripheral surface of the connecting seat 100. The limiting ring 150 surrounds the outer peripheral surface of the connecting seat 100 and is located above the receiving groove 101. After the connecting seat 110 passes through the mounting hole 311, the limiting ring 150 can abut against the top surface of the base plate 310, restricting the connecting seat 110 from further passing through the mounting hole 311, so that the distance between the locking member 110 in the locked state and the bottom surface of the base plate 310 is not too large.

[0037] Ideally, after the handle is installed in place, the limiting ring 150 and the locking member 110 in the locked state can clamp the base plate 310, and the connecting seat 100 is not easy to wobble relative to the base plate 310, which further improves the stability of the handle installed on the base plate 310.

[0038] In some embodiments, the receiving groove 101 forms an opening on the bottom surface of the connecting seat 100, through which the locking member 110 and the elastic member 120 can be installed into the receiving groove 101 to facilitate the assembly of the locking member 110 and the elastic member 120. A cover plate 160 is fixed to the bottom of the connecting seat 100, which covers the opening of the receiving groove 101 on the bottom surface of the connecting seat 100. This can isolate and protect the locking member 110 and the elastic member 120, and can also reduce the entry of dust and other impurities into the receiving groove 101. Meanwhile, the cover plate 160 is provided with a through groove 161. The extension direction of the through groove 161 is parallel to the sliding direction of the locking member 110 relative to the connecting seat 100. The pressing plate 130 extends out of the through groove 161 to extend beyond the connecting seat 100, so that the user can operate the pressing plate 130 from the outside. The existence of the through groove 161 provides space for the pressing plate 130 to slide with the locking member 110. Moreover, the through groove 161 can also guide the movement of the pressing plate 130 to prevent its movement direction from deviating.

[0039] Furthermore, the cover plate 160 can be fixed to the bottom of the connector 100 by various methods such as screw fixing, snap-fit ​​connection or adhesive fixing.

[0040] In some embodiments, the holding rod 210 extends horizontally. The upper ends of the two pull rods 200 are respectively connected to the two ends of the holding rod 210, forming a structure similar to a "U" shape. The horizontal length of the horizontally extending holding rod 210 is greater, providing a larger space for the user to hold and making the operation more convenient.

[0041] In other embodiments, the holding rod 210 can also be arranged vertically. The upper ends of the two pull rods 200 are both connected to the lower end of the holding rod 210, forming a structure similar to a "Y" shape, which can also be held by the user.

[0042] Of course, the holding rod 210 and the two pull rods 200 can also be connected in other shapes.

[0043] A rubber sleeve can be sleeved on the holding rod 210 to increase the comfort of the user's grip.

[0044] In some embodiments, the lower end of the pull rod 200 is rotatably connected to the connecting seat 100. When in use, the user can rotate the pull rod 200 to a corresponding angle as needed, making it more flexible and convenient to use.

[0045] Of course, the pull rod 200 can also be fixedly connected to the connecting seat 100 and form a preset angle relative to the horizontal direction. In this case, the pull rod 200 cannot be adjusted in angle relative to the connecting seat 100, and the user pulls the pull rod 200 at a specific angle.

[0046] In some embodiments, the pull rod 200 can be telescopic to adjust its length to meet the needs of different users or different usage scenarios. Since the telescopic structure of the pull rod already belongs to conventional technical means, its specific implementation will not be elaborated here.

[0047] In some embodiments, the elastic member 120 can be a spring. The locking member 110 can be provided with a groove. The spring is located in the groove to restrict the movement of the spring, enabling it to stably provide an elastic force. One end of the spring can abut against the inner wall of the groove, and the other end can abut against the inner wall of the accommodating groove 101 or other stoppers inside the accommodating groove 101.

[0048] In some embodiments, the implementation method of detachably combining the bottom plate 310 of the first vehicle body and the bottom plate 310 of the second vehicle body together already belongs to the prior art and will not be elaborated here.

[0049] The terms and words used in the above description and claims are not limited to their literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should clearly understand that the above description of various embodiments of the present invention is only for the purpose of illustration, rather than to limit the present invention as defined by the appended claims and their equivalents.
