Referring to fig. 6, the supporting unit 20 is detachably mounted above the base 11 of the base unit 10, and includes a supporting plate 21 for fixing the basket 200, an engaging portion 22 disposed on the supporting plate 21 and corresponding to the pushing member 13, and a plurality of hooks 23 connected to the supporting plate 21 and detachably engaged with the engaging slots 116, wherein the engaging portion 22 is in a shape of a protrusion and disposed on the bottom surface of the supporting plate 21, and the hooks 23 are in an L shape and disposed on the bottom surface of the supporting plate 21.

For a further understanding of the invention with the components and the resultant effects, operational advantages, and capabilities thereof, reference is made to the following description, which is believed to provide a further and more thorough understanding of the invention.

As shown in fig. 4 to 6, when the base unit 10 is completely assembled and is fastened to the bicycle rack 100 by screws, and under a normal state, the body 131 of the ejector 13 is under the elastic force of the elastic member 14, so that the protrusion 133 extends from the through hole 115 and protrudes from the top wall 111, and the ejector 13 is located at a fixed position, at this time, the linkage block 134 corresponds to and is sleeved on the included angle portion 123 between the detent portions 122, the protrusion 133 of the ejector 13 is stopped at one side of the embedding portion 22, the hook blocks 23 are respectively embedded in the fastening grooves 116 and respectively embedded in the bottom surface of the top wall 111, and the carrying unit 20 is fixed on the base 11.

As shown in fig. 7 and 8, when the user presses one of the operation portions 121 to retract toward the inside of the sliding slot 114 (as shown by the arrow in fig. 7), the operating element 12 can be linearly displaced along the horizontal axis X, and one of the brake portions 122 corresponding to the operating portion 121 is used to press and drive the linking block 134 to move downward, the pushing-up member 13 is linked to pivot relative to the supporting portion 119 of the receiving member 113 by using the pivot 132 as a pivot point, and the projection 133 is transformed from a fixed position projecting from the top wall 111 to a release position, in which it is lowered towards the inside of the vessel 117, in which, the protrusion 133 does not block the engaging portion 22, the operator can operate the carrying unit 20 to move laterally along the longitudinal axis Y relative to the base unit 10, and make the hooks 23 correspond to the openings of the engaging slots 116, the carrying unit 20 can be easily detached from the base unit 10 (see fig. 9).

Therefore, as shown in fig. 7 to 9, pressing one of the operation portions 12 can convert the pushing member 13 from the fixed position to the releasing position, so that the detachment of the carrying unit 20 from the base unit 10 is easier.

Furthermore, when the operator wants to mount the carrying unit 20 relative to the base unit 10 and the pushing member 13 is located at the fixed position under the action of the elastic member 14, the operator presses one of the operation portions 12 and converts the pushing member 13 from the fixed position to the release position (in the process, the elastic member 14 is compressed and stores the releasing elastic force), the operator then inserts the hooks 23 of the carrying unit 20 into the fastening slots 116 respectively (as shown in fig. 8), at this time, the hooks 23 are not fastened with the top wall 111, the operator then operates the carrying unit 20 to move laterally along the longitudinal axis Y relative to the base unit 10 and inserts the hooks 23 into the bottom surface of the top wall 111 at one side of the fastening slots 116 respectively, the fastening portion 22 is also displaced to a fixed position, when the operator releases the pressing force on the operation portion 121, the releasing elastic force of the elastic member 14 is utilized, the pushing member 13 is pivoted relative to the receiving member 113 by using the pivot 132 as a pivot point, and the protrusion 133 is converted from the releasing position to a fixed position protruding from the top wall 111, and blocks the engaging portion 22, so that the carrying unit 20 can be stably fixed on the base unit 10, and the operating member 12 can be linked to move reversely along the transverse axis X to return to the original state by moving the linking block 134 and simultaneously moving the corresponding locking portion 122.

Therefore, the advantages of the carrying device with quick release function of the present invention can be summarized as follows, so the object of the present invention can be achieved:

firstly, by using the operating member 12, the pushing member 13, the elastic member 14, etc. of the base unit 10 to be installed inside the base 11, even if the carrying unit 20 can be detached from the base unit 10, it can be ensured that these components are not completely exposed, and are not easily damaged by moisture and dust. Moreover, the base unit 10 is fixed on the bicycle shelf 100, and the detachment of the carrying unit 20 does not affect the positioning and connection structure of the operating member 12, the ejector 13, the elastic member 14 and other components, so as to prolong the service life of the product.

The operating element 12 is a zigzag elongated rod and has the operating parts 121 protruding outside the peripheral wall 112 of the base 10 and the middle section 120 slidably nested in the slot 110, so that the operating element 12 cannot easily separate from the slot 114 of the base 11 when being mounted inside the slot 114 of the base 10 by the action of the slot 110 and the slot 114 being staggered along the longitudinal axis Y, thereby improving the positioning performance of the operating element 12.

Thirdly, the operating part 12 has two operating parts 121 protruding outside the peripheral wall 112 of the base 10, so that the operator can press or pull from both left and right sides, and the operating mode is diversified.

The present invention has been described in detail in order to enable those skilled in the art to understand the invention and to practice it, and it is not intended to limit the scope of the invention, and all equivalent changes and modifications made according to the spirit of the present invention should be covered by the present invention.
