[0023] For the convenience of understanding the present utility model, the present utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is expressed as "fixed to" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween. When an element is expressed as "connected to" another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are only for the purpose of illustration.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in this specification in the description of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0025] When transporting items with existing carts, in order to ensure that the items to be transported do not shake during transportation, the items to be transported are often fixed to the cart by screwing or clamping. When using the screwing fixing method, usually a screw connector is used to fix the item to be transported to the cart. Further, in order to ensure the reliability of the connection of the screw connector during transportation, it is necessary to extend the length of the screw connector and increase the number of turns of tightening the screw connector. As a result, when disassembling the item to be transported after the transportation is completed, the steps are cumbersome and the disassembly is difficult, thereby increasing the time cost and labor cost.

[0026] To overcome the above problems and on the premise of ensuring a stable connection between the item to be carried and the cart, the present utility model provides a cart mounting structure that can be applied to a cart to enable quick disassembly between the item to be carried and the cart.

[0027] Please refer to Figure 1 and Figure 2 , the cart mounting structure 1000 includes a bracket assembly 1, a clamping assembly 2, and a fastening assembly 3. The clamping assembly 2 is movably arranged on the bracket assembly 1, and the fastening assembly 3 is connected to the clamping assembly 2 through a hook.

[0028] For the above clamping assembly 2, please refer to Figure 1 and Figure 2 , the clamping assembly 2 includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 is rotatably arranged on the bracket assembly 1, and the second clamping member 22 is arranged on the bracket assembly 1. The first clamping member 21 and the second clamping member 22 are arranged opposite to each other. The first clamping member 21 is provided with a first clamping groove 211, and the second clamping member 22 is provided with a second clamping groove 221. The orientations of the first clamping groove 211 and the second clamping groove 221 are opposite. Specifically, the orientation of the first clamping groove 211 is opposite to that of the second clamping groove 221. It can be understood that the second clamping member 22 can be directly fixed to the bracket assembly 1 or rotatably arranged on the bracket assembly 1, thus forming different technical solutions.

[0029] For the above fastening assembly 3, please refer to Figure 1 and Figure 2 , the fastening assembly 3 includes a fastening member 31. One end of the fastening member 31 is provided with a first hook 311, and the other end of the fastening member 31 is provided with a second hook 312. The orientations of the first hook 311 and the second hook 312 are opposite. Specifically, the orientation of the first hook 311 is opposite to that of the second hook 312, and the orientation of the first hook 311 is the same as that of the first clamping groove 211, so that the first hook 311 can be smoothly engaged with the first clamping groove 211. The orientation of the second hook 312 is the same as that of the second clamping groove 221, so that the second hook 312 can be smoothly engaged with the second clamping groove 221.

[0030] It can be understood that there are multiple fastening assemblies 3, and the number of the fastening assemblies 3 is a positive integer greater than or equal to one. The fastening assemblies 3 are connected to the item to be transferred, so that the item to be transferred is engaged with the clamping assembly 2 through the fastening assemblies 3, thereby realizing the fixation of the item to be transferred.

[0031] It should be noted that the connection method between the fastening component 3 and the component to be transferred includes, but is not limited to, screwing, clamping, etc. In this embodiment, preferably, the fastening component 3 is fixed to the component to be transferred by screwing. Specifically, the fastening component 3 includes a screw member 32, and the fastening member 31 is provided with a screw hole 313. The screw member 32 passes through the screw hole 313 and is screwed onto the component to be transferred.

[0032] A brief description of the cooperation and working relationship between the above-mentioned clamping component 2 and the fastening component 3 is as follows. Please refer to Figure 3 , when the first clamping member 21 rotates relative to the bracket assembly 1, the distance between the first clamping groove 211 and the second clamping groove 221 can be adjusted; by rotating the first clamping member 21, the rotation of the first clamping groove 211 is driven, so that the notch direction of the first clamping groove 211 changes, and thus the distance between the first clamping groove 211 and the second clamping groove 221 changes. It can be understood that the distance between the notch of the first clamping groove 211 and the notch of the second clamping groove 221 is defined as the distance between the first clamping groove 211 and the second clamping groove 221.

[0033] Please refer to Figure 4 , when the first clamping member 21 is in the preset first position A, the first hook 311 is firmly clamped in the first clamping groove 211, and the second hook 312 is firmly clamped in the second clamping groove 221. The fastening member 31 and the clamping component 2 are in a locked state. At this time, the distance between the first clamping groove 211 and the second clamping groove 221 is the farthest; when an external force acts on the first clamping member 21 to drive it to rotate, the notch of the first clamping groove 211 deflects, so that the distance between the notch of the first clamping groove 211 and the notch of the second clamping groove 221 gradually decreases with the action of the external force. When the first clamping member 21 is in the preset second position C, the first hook 311 can be disengaged from the first clamping groove 211, and the second hook 312 can be disengaged from the second clamping groove 221. The fastening member 31 and the clamping component 2 are in an unlocked state. At this time, the distance between the first clamping groove 211 and the second clamping groove 221 is the closest.

[0034] In some embodiments, please refer to Figure 1 and Figure 2 and Figure 5 , the first clamping member 21 includes a first rotating shaft 212 and a first fastening member 213. The first rotating shaft 212 is rotatably arranged on the bracket assembly 1. One end of the first fastening member 213 is fixed to the first rotating shaft 212, and the other end of the first fastening member 213 bends and extends to form the first clamping groove 211. It can be understood that the first rotating shaft 212 is a columnar body, and a bending portion can be provided according to actual needs, so that when an external force drives the first rotating shaft 212 to rotate, the force can be more conveniently applied to the first rotating shaft 212. Specifically, in some embodiments, please refer to Figure 5The first rotating shaft 212 includes a first rotating portion 2121 and a first bending portion 2122, wherein the first bending portion 2122 is perpendicular to the first rotating portion 2121. When the external force is driven by a human hand, the human hand holds the first bending portion 2122 and pushes the first bending portion 2122 to rotate, thereby driving the first rotating portion 2121 to rotate, and further driving the first fastener 213 fixedly connected to the first rotating shaft 212 to rotate. The perpendicular first bending portion 2122 and the first rotating portion 2121 form a labor-saving structure. Compared with the first rotating shaft 212 provided with only the first rotating portion 2121, applying force to the first bending portion 2122 can reduce the force required to drive the first rotating shaft 212 to rotate.

[0035] It can be understood that the fixing method of the first fastener 213 and the first rotating shaft 212 includes but is not limited to screwing, riveting, welding, etc. In this embodiment, preferably, the connection method of the first fastener 213 and the first rotating shaft 212 is riveting.

[0036] It should be noted that in order to improve the user experience of applying force to the first bending portion 2122, in some embodiments, refer to Figure 5 The first bending portion 2122 is provided with a gripping portion 2122a on its outer cover. The gripping portion 2122a is in the shape of a rectangular block structure, thereby increasing the contact area between the human hand and the first bending portion 2122 and improving the gripping experience.

[0037] In some embodiments, please refer to Figure 1 The bracket assembly 1 includes a first cross bar 11, which can be fixed on the cart. The first cross bar 11 is provided with a first rotating hole 111, and the first rotating hole 111 is used to accommodate the first rotating shaft 212, and provide support and limit the circumferential rotation of the first rotating shaft 212 along the first rotating hole 111; the first rotating shaft 212 is inserted into the first rotating hole 111, and the first rotating shaft 212 can rotate in the first rotating hole 111.

[0038] It can be understood that in order to enhance the rotation experience of the first rotating shaft 212 in the first rotating hole 111, in some embodiments, a bearing can be arranged between the first rotating shaft 212 and the inner wall of the first rotating hole 111, thereby converting the surface contact between the first rotating shaft 212 and the inner wall of the first rotating hole 111 into line contact of the bearing ball, thereby reducing the frictional resistance of rotation, and the line contact rotation mode also further extends the service life of the first rotating shaft 212.

[0039] In some embodiments, see Figure 1 , Figure 4 and Figure 5The first cross bar 11 is provided with a fixing groove 112, and the fixing groove 112 is provided on the surface of the cross bar away from the first fastener 213; the first clamping member 21 also includes a fixing member 214, and the fixing member 214 is fixed to the other end of the first rotating shaft 212, and the fixing member 214 is provided with a convex portion 2141, and the convex portion 2141 corresponds to the fixing groove 112, and the convex portion 2141 can be received in the fixing groove 112; the first rotating shaft 212 is inserted into the first rotating hole 111 and partially extends out of the first rotating hole 111, and is fixedly connected with the first fastener 213, and the first rotating shaft 212 extends out of the first rotating hole 111 so that a first gap 12 is formed between the first fastener 213 and the first cross bar 11, so that the first rotating shaft 212 can also slide along the axial direction of the first rotating hole 111; when the first rotating shaft 2 12 is located at the preset first position A, the protrusion 2141 is also aligned with the fixing groove 112, and at this time the central axis of the protrusion 2141 is colinear with the central axis of the fixing groove 112 to ensure that the protrusion 2141 can be accurately received in the fixing groove 112. When the first rotating shaft 212 is driven to slide axially along the first rotating hole 111 so that the protrusion 2141 is snapped into the fixing groove 112, the protrusion 2141 and the fixing groove 112 cooperate to limit the first clamping member 21 to be located at the preset first position A. When the first clamping member 21 needs to be changed from the preset first position A to the preset second position C, it is necessary to drive the first rotating shaft 212 to slide axially along the first rotating hole 111 to the preset middle position B so that the protrusion 2141 is disengaged from the fixing groove 112 to facilitate the rotation of the first clamping member 21.

[0040] It can be understood that in order to facilitate the protrusion 2141 to be inserted into the fixing groove 112, a chamfer is provided on the end face of the protrusion 2141 facing the fixing groove 112, and the chamfer is used to guide the protrusion 2141 to be inserted into the fixing groove 112, so that when the first rotating shaft 212 slides axially along the first rotating hole 111, a slight deflection or shaking occurs, and the protrusion 2141 can also be smoothly inserted into the fixing groove 112.

[0041] In some embodiments, see Figure 5 The setting of the fixing groove 112 can be directly formed by digging a groove on the first crossbar 11, or by adding a component, setting the fixing groove 112 on the newly added component, and then assembling the newly added component on the first crossbar 11. In this embodiment, preferably, by adding a component: a fixing fitting 13, the fixing groove 112 is set on the fixing fitting 13, and the fixing fitting 13 is screwed to the first crossbar 11. Through the fixing fitting 13, the fixing groove 112 is transferred to the fixing fitting 13, thereby reducing the impact on the structural strength of the first crossbar 11, and the fixing fitting 13 can also be screwed to different positions of the first crossbar 11 as needed to adapt to the first clamping member 21 and the second clamping member 22 with different spacings, thereby improving the applicability of the cart installation structure 1000.

[0042] In some embodiments, refer to Figure 1 and Figure 2 , the first engaging member 21 includes a first elastic member 215, and the first elastic member 215 is received in the first gap 12; one end of the first elastic member 215 is connected to the first rotating shaft 212. To achieve the connection between the first elastic member 215 and the first rotating shaft 212, a first sleeve (not labeled) is sleeved on the circumferential side of the first rotating shaft 212. One end of the first elastic member 215 abuts against the first sleeve, and the other end of the first elastic member 215 abuts against the surface of the first cross bar 11 facing away from the fixing member 214; the first elastic member 215 is used to keep the convex portion 2141 snapped into the fixing groove 112, that is, when the fastening member 31 and the engaging assembly 2 are in the locked state, the first elastic member 215 relies on its own elastic potential energy to make the convex portion 2141 snap into the fixing groove 112, so that the first rotating member maintains the preset first position A and will not cause the locked state to fail due to factors such as shaking that do not actively release the locked state. In this embodiment, the first elastic member 215 is preferably a spring.

[0043] In some embodiments, refer to Figure 1 , the first rotating shaft 212 is divided into two parts: a first rotating shaft section 212a and a second rotating shaft section 212b. The first rotating shaft section 212a is inserted into the first rotating hole 111. The bracket assembly 1 includes a second cross bar 14, and the second cross bar 14 is parallel to and spaced from the first cross bar 11; the second cross bar 14 is provided with a second rotating hole 141, and the first rotating shaft 212 is inserted into the second rotating hole 141, that is, the second rotating shaft section 212b is inserted into the second rotating hole 141, and the first rotating shaft 212 can also slide along the axial direction of the second rotating hole 141, that is, the second rotating shaft section 212b can also slide along the axial direction of the second rotating hole 141.

[0044] It can be understood that the second cross bar 14 enhances the overall stability of the cart mounting structure 1000. Compared with only the first cross bar 11 being provided, when the first rotating shaft 212 slides along the axial direction of the first rotating hole 111, shaking or deflection will occur. The second cross bar 14 and the first cross bar 11 jointly restrict the sliding of the first rotating shaft 212, so that the sliding trajectory of the first rotating shaft 212 can proceed as expected.

[0045] In some embodiments, refer to Figure 1 and Figure 2, the first clamping member 21 further includes a first limiting member 216 disposed on the first rotating shaft 212, that is, the first limiting member 216 is connected to the second rotating shaft segment 212b; the first limiting member 216 is located on the part of the first rotating shaft 212 extending out of the second cross bar 14 along the first cross bar 11 towards the second cross bar 14, that is, the first limiting member 216 is located at the end of the second rotating shaft segment 212b away from the first fastening member 21, and a second gap 15 is formed between the first limiting member 216 and the first cross bar 11, and the second gap 15 enables the first rotating shaft 212 to slide along the axial direction of the first rotating hole 111. The length of the second gap 15 is equal to the length of the first gap 12 to ensure the effectiveness of the first limiting member 216 when restricting the stroke of the first rotating shaft 212.

[0046] It should be noted that the structure of the first limiting member 216 is the same as that of the first fastening member 213, and the only difference between the two is the length. The first limiting member 216 can also be engaged with the engaging member 31.

[0047] In some embodiments, for more rapid and convenient disassembly of the engaging component 3, please refer to Figure 1 , the second clamping member 22 is rotatably disposed on the bracket assembly 1. When the second clamping member 22 rotates relative to the bracket assembly 1, the distance between the first clamping groove 211 and the second clamping groove 221 can be adjusted to switch the engaging member 31 between the locked state and the unlocked state.

[0048] It should be noted that the overall structure of the second clamping member 22 is the same as that of the first clamping member 21. The difference between the two is that the rotation directions of the first clamping member 21 and the second clamping member 22 are opposite. When the rotation direction of the first clamping member 21 is clockwise, the rotation direction of the second clamping member 22 is counterclockwise.

[0049] Specifically, the second clamping member 22 includes a second rotating shaft 222 and a second fastening member 223. The second rotating shaft 222 is rotatably disposed on the bracket assembly 1. One end of the second fastening member 223 is fixed to the second rotating shaft 222, and the other end of the second fastening member 223 bends and extends to form a second clamping groove 221.

[0050] For the specific structure and function of the second clamping member 22 and the assembly relationship between the second clamping member 22 and the bracket assembly, reference can be made to the structure and function of the first clamping member 21 in the above embodiments, and they will not be elaborated one by one in this embodiment. The second clamping member 22 and the first clamping member 21 are mirror-symmetrical about the center line of the bracket assembly 1.

[0051] In an embodiment of the present utility model, a trolley mounting structure 1000 includes a bracket assembly 1, a clamping assembly 2, and a fastening assembly 3. The clamping assembly 2 is rotatably arranged on the bracket assembly 1. The clamping assembly 2 is provided with a first clamping groove 211 and a second clamping groove 221. The fastening assembly 3 is connected to the clamping assembly 2 and is fixed to the piece to be carried. The fastening assembly 3 is provided with a first hook 311 and a second hook 312. The first hook 311 is hooked with the first clamping groove 211, and the second hook 312 is hooked with the second clamping groove 221 to realize the connection between the fastening assembly 3 and the clamping assembly 2. Specifically, the clamping assembly 2 includes a first clamping member 21 and a second clamping member 22.
