[0027] 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.

[0028] 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.

[0029] 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.

[0030] An embodiment of this utility model provides a detachable handle, such as... Figure 1-4 As shown, the device includes a connecting base 100 and a pull rod 200. The lower end of the pull rod 200 is connected to the connecting base 100, and the user can pull the pull rod 200. The connecting base 100 has receiving grooves 101 on two opposing sides. The two receiving grooves 101 can be connected to each other or independent of each other. Each receiving groove 101 contains a locking element 110 and an elastic element 120. The locking elements 110 in both receiving grooves 101 can slide parallel to each other in a direction of approach, thus allowing them to move closer or further apart. As the locking element 110 slides relative to the connecting base 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 element 110 is in the locked state, since at least part of it extends out of the receiving groove 101, the extended portion protrudes from the side of the connecting base 100, serving as a limiting element. When the locking member 110 is in the unlocked state, it no longer serves as a limit because it is retracted into the receiving groove 101.

[0031] 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 floor of the vehicle body, the force of the elastic member 120 can keep the connecting seat 100 connected to the floor. Without external force, the connecting seat 100 is difficult to detach from the floor, 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.

[0032] Specifically, when using the detachable handle of this embodiment, a mounting hole adapted to the connecting seat 100 can be provided on the bottom plate of the vehicle body. When installing the handle of this embodiment, the user can press the pressing plate 130, so that the locking member 110 overcomes the force of the elastic member 120, and the locking member 110 switches to the unlocked state so as not to block the connecting seat 100 from being inserted into the mounting hole. Then, the connecting seat 100 is passed through the mounting hole, 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 bottom plate to prevent the connecting seat 100 from disengaging from the mounting hole, thereby fixing the handle to the bottom plate of the vehicle body. When disassembling the handle in this embodiment, the user can press the pressing plate 130, causing the locking member 110 to overcome the force of the elastic member 120. The locking member 110 switches to the unlocked state, and the retracted locking member 110 no longer restricts the connecting seat 100. Then, the connecting seat 100 is pulled out from the mounting hole, and the handle can be separated from the vehicle body, completing the disassembly. Therefore, the handle in this embodiment can be installed on or removed from the vehicle body as needed, facilitating replacement after the handle is damaged. When the user needs to use the handle, it is fixed to the vehicle body; when the user does not need the handle, it is removed from the vehicle body, reducing the space occupied by the vehicle body and making it more convenient for the user.

[0033] 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, the side edge of the top opening of the mounting hole 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. 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.

[0034] 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.

[0035] 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, the limiting ring 150 abuts against the top surface of the base plate, restricting the connecting seat 110 from further passing through the mounting hole, so that the distance between the locking member 110 in the locked state and the bottom surface of the base plate is not too large.

[0036] 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, and the connecting seat 100 is not easy to wobble relative to the base plate, which further improves the stability of the handle installed on the base plate.

[0037] 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.

[0038] 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.

[0039] In some embodiments, the lower end of the pull rod 200 is rotatably connected to the connecting seat 100, allowing the user to rotate the pull rod 200 to the corresponding angle as needed, making it more flexible and convenient to use.

[0040] 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 relative to the connecting seat 100, and the user can pull the pull rod 200 at a specific angle.

[0041] In some embodiments, the upper end of the lever 200 is provided with a grip portion 201 for the user to hold. The grip portion 201 can be bent into a "7"-shaped structure, making it easier for the user to grip and requiring less effort when pulling. A rubber sleeve may be fitted onto the grip portion 201 to increase the user's grip comfort.

[0042] The 200mm pull rod is telescopic, allowing for length adjustment to meet the needs of different users or usage scenarios. Since the telescopic structure of the pull rod is a standard technical feature, its specific implementation will not be elaborated upon here.

[0043] In some embodiments, the elastic element 120 may be a spring, and the locking element 110 may be provided with a groove in which the spring is located, restricting the movement of the spring so that it can stably provide elastic force. One end of the spring may abut against the inner wall of the groove, and the other end may abut against the inner wall of the receiving groove 101 or other stops inside the receiving groove 101.

[0044] An embodiment of this utility model also provides a handcart, such as Figure 5 and Figure 6 As shown, the vehicle body includes a detachable handle from any of the above embodiments. For a detailed description of the detachable handle, please refer to the above embodiments, which will not be repeated here.

[0045] The vehicle body includes a base plate 310 and multiple casters 320 disposed 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 fixed casters or swivel casters. The top surface of the base plate 310 is provided with a mounting hole 311 extending to its bottom surface. The mounting hole 311 is adapted to the connecting seat 100, and the connecting seat 100 can pass through the mounting hole 311.

[0046] When installing the handle in this embodiment, the user can press the pressing plate to make the locking member overcome the force of the elastic member and switch the locking member to the unlocked state so as not to block the connector 100 from being inserted into the mounting hole 311. Then, the connector 100 is passed through the mounting hole 311. After that, the pressing plate is released. Under the action of the elastic member, the locking member remains locked. The outwardly protruding locking member 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.

[0047] When disassembling the handle in the above embodiment, the user can press the pressing plate to make the locking member overcome the force of the elastic member, and the locking member switches to the unlocked state. The retracted locking member no longer restricts the connecting seat 100. Then, the connecting seat 100 is pulled out from the mounting hole 311, and the handle can be separated from the vehicle body to complete the disassembly.

[0048] In some embodiments, mounting holes 311 can be provided on all four sides of the base plate 310, and the connecting seat 100 can be fixed in any one of the mounting holes 311. Users can pull the vehicle body from any direction of the base plate 310, making it more flexible to use.

[0049] In some embodiments, the base plate 310 is provided with a matching assembly structure and a connecting structure. The assembly structure on the base plate 310 can be connected to the connecting structure of another vehicle body to assemble and connect the two vehicle bodies together. For example... Figure 7 As shown, the floor plates 310 of multiple vehicle bodies are combined and fixed together, which is equivalent to increasing the area of ​​the floor plate 310. Larger goods can be placed on the floor plate 310, making it more convenient to transport larger goods.

[0050] Furthermore, such as Figure 5 and Figure 6 As shown, the assembly structure includes assembly inserts 330 located at the side edges of one long side and one short side of the bottom surface of the base plate 310; the connecting structure includes connecting plates 340 located at the side edges of the other long side and the other short side of the base plate 310, with a through connecting hole 341 on the top surface of the connecting plate 340. The assembly insert 330 of one of the two vehicle bodies can be inserted into the connecting hole 341 of the other vehicle body to connect the two vehicle bodies together.

[0051] Specifically, the assembly insert 330 at the side edge of the long side of the floor plate 310 of one vehicle body can be inserted into the connecting hole 341 at the side edge of the long side of the floor plate 310 of the other vehicle body, so that the long sides of the floor plates 310 of the two vehicle bodies are connected together. The assembly insert 330 at the side edge of the short side of the floor plate 310 of one vehicle body can be inserted into the connecting hole 341 at the side edge of the short side of the floor plate 310 of the other vehicle body, so that the short sides of the floor plates 310 of the two vehicle bodies are connected together.

[0052] In the above embodiments, the long side refers to the side extending along the length direction, and the short side refers to the side extending along the width direction.
