Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.It should be noted that, accompanying drawing of the present invention all adopts the form of simplification and all uses non-ratio accurately, only in order to object that is convenient, the aid illustration embodiment of the present invention lucidly.
As shown in Figure 1, the invention provides a kind of supermarket shopping car connecting device, comprise: the second component 200 being arranged on the first component 100 below shopping cart 300 bottom bevel 310 and being arranged on above described inclined-plane 310, when two shopping carts 300 are contacted, first, second parts 100,200 described are mutually locked by thrust or unlock.The present invention by arranging first, second parts 100,200 on the bottom bevel 310 of shopping cart 300, and utilize the thrust of staff or client to complete the sealed and unlocking motion of these first, second parts 100,200, shopping cart 300 is avoided to slip off in transportation, staff in removal process is facilitated to transport shopping cart 300, and then improve the work efficiency of supermarket staff, also make things convenient for customers simultaneously and take out shopping cart 300 fast when doing shopping.
As shown in Figure 2, as preferably, described first component 100 comprises: the cylinder 110 that Open Side Down, is arranged on the tooth post 120 in cylinder 110, described tooth post 120 is fixed on bottom cylinder 110 by spring 130, and the circumference place at described tooth post 120 top is provided with some first helical teeth 121.
As preferably, described spring 130 is affixed by base 140 and described tooth post 120.
Continue referring to Fig. 2, described second component 200 comprises: be arranged on the mount pad 210 on described inclined-plane 310, be fixed on the disk 220 on described mount pad 210, the runner 230 be connected with described disk 220 movable end, described runner 230 is provided with the second helical teeth 231 engaged with described first helical teeth 121.
As preferably, described runner 230 is also provided with guide rail 240, further, as shown in Figure 3, described cylinder 110 inwall is provided with the guide groove 111 corresponding with described guide rail 240, is also provided with guiding rib 112 between the guide groove 111 in described cylinder 110 and guide groove 111.
Please emphasis with reference to Fig. 4, as preferably, described guiding rib 112 comprises: the first guiding surface 1121 and the second guiding surface 1122, wherein the length of the first guiding surface 1121 is greater than the length of the second guiding surface 1122.Further, described guide rail 240 is provided with and described first, second guiding surface 1121,1122 corresponding the 3rd guiding surfaces 241 away from one end of the second helical teeth 231.
As preferably, described guide rail 240 is provided with two groups or four groups.
As preferably, first, second parts 100,200 described all adopt plastics or metallic material to make.
Please refer to Fig. 4, and composition graphs 1 to Fig. 3, will the working process of the connecting device of supermarket shopping car of the present invention be described in detail below:
Locking process: when two shopping carts 300 are contacted, the Part II 200 above first shopping cart 300 mates with the Part I 100 below second shopping cart 300, completes lock out action.
Particularly, two shopping carts 300 near time, the runner 230 of Part II 200, by external force (thrust) effect, contact, and Compress Spring 130 moves along cylinder 110 inwall with tooth post 120.It should be noted that, now, first, second helical teeth 121,231 only tip contact, and non-fully engagement.Again due in the process, guide rail 240 moves bottom cylinder 110 along guide groove 111, that is, runner 230 by guide rail 240 and guide groove 111 spacing, can not rotate.After guide rail 240 other end skids off guide groove 111, first, second helical teeth 121,231 engages, and in this process, can not rotate because tooth post 120 is fixed on base 140, therefore, in this process, runner 230 rotates and then first, second helical teeth 121,231 is engaged.Now, guide rail 240 misplaces with guide groove 111 after rotation, the top of the 3rd guiding surface 241 on it and the tip contact of the first guiding surface 1121.
When external force disappears, spring 130 rebounds, and the 3rd guiding surface 241 on guide rail 240 slides along described first guiding surface 1121, slides into after bottom the first guiding surface 1121 and stops, now two shopping carts 300 are in the lock state, and first, second helical teeth 121,231 is in non-engagement state.
Releasing process:
External thrust pushes, and makes spring 130 by compression, and guide rail 240 rotates after departing from the first guiding surface 1121, and then first, second helical teeth 121,231 is engaged.After external force disappears, spring 130 rebounds, now the 3rd guiding surface 241 and the second guiding surface 1122 top contact of guide rail 240, and slip in guide groove 111 along the second guiding surface 1122, guide rail 240 is made to enter into guide groove 111, unblock completes, and the shopping cart 300 of two series windings departs from mutually.
In sum, supermarket shopping car connecting device of the present invention, comprise: the second component 200 being arranged on the first component 100 below shopping cart 300 bottom bevel 310 and being arranged on above described inclined-plane 310, when two shopping carts 300 are contacted, first, second parts 100,200 described are mutually locked by thrust or unlock.The present invention by arranging first, second parts 100,200 on the bottom bevel 310 of shopping cart 300, and utilize the thrust of staff or client to complete the sealed and unlocking motion of these first, second parts 100,200, shopping cart 300 is avoided to slip off in transportation, staff in removal process is facilitated to transport shopping cart 300, and then improve the work efficiency of supermarket staff, also make things convenient for customers simultaneously and take out shopping cart 300 fast when doing shopping.
Obviously, those skilled in the art can carry out various change and modification to invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
