Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
referring to the children trolley shown in Fig. 1～4, comprise folding vehicle frame, be located at front portion at the bottom of vehicle frame front-wheel 4, be located at the trailing wheel 5 at rear portion at the bottom of vehicle frame.Vehicle frame comprises push rod 1, front frame 2, after poppet 3, and front-wheel 4 is arranged on the bottom of front frame 2, and trailing wheel 5 is arranged on the bottom of after poppet 3.
push rod 1 comprises lower push-rod 101 and upper push-rod 102, lower push-rod 101 has the lower push-rod 101 of hollow tube chamber, the bottom of upper push-rod 102 can be plugged in slidably along its length and in the above-mentioned hollow tube chamber of lower push-rod 101, make the push rod 1 can be flexible along self length direction, between upper push-rod 102 and lower push-rod 101, be also provided with push rod locking piece 103, this push rod locking piece 103 can be by wherein arranging stop pin on parts in upper push-rod 102 and 101 liang of parts of lower push-rod, on another parts, offering lock hole can realize again, push rod locking piece 103 should at least have two latched positions, thereby lock mutually while making upper push-rod 102 expansion relative to lower push-rod 101 with folding.
the bottom of lower push-rod 101 rotates and is connected with the top of after poppet 3, both places of being rotationally connected are provided with the first locking piece 7, the electric bell that this first locking piece 7 adopts, when electric bell locking, lower push-rod 101 interfixes with after poppet 3, and in the time of electric bell release, lower push-rod 101 can relatively rotate with after poppet 3.Electric bell is the conventional a kind of locking member in this area, no longer its detailed structure is repeated herein, wherein electric bell has two electric bell covers that can mutually rotate, when two electric bell covers rotate mutually, electric bell gets final product release, two electric bell covers are connected on lower push-rod 101 and after poppet 3, only need make like this push rod 1 rotation relative to after poppet 3 can realize the release of electric bell in the time of release.
shown in each accompanying drawing, the middle part of after poppet 3 Connection Block 6 that has been permanently connected, the length direction of Connection Block 6 distributes along the fore-and-aft direction of vehicle frame, the middle part of front frame 2 is connected to by rotating shaft on the front portion of Connection Block 6 rotationally near the position on top, and the axial line of above-mentioned rotating shaft distributes along the left and right directions of vehicle frame.Between the top of the rear portion of Connection Block 6 and front frame 2, being provided with on the rear portion that the second locking piece 8, the second locking pieces 8 can fix on the upper lock of front frame 2 Connection Block 6 interfixes both.
referring to Fig. 1, Fig. 2, shown in Fig. 4, the second locking piece 8 comprises dead bolt 81 and the first spring 82 be located on front frame 2, be opened in the locked groove 83 on Connection Block 6, the top of front frame 2 has hollow stem chamber, the depth direction in this hollow stem chamber extends along the length direction of front frame 2, dead bolt 81 can be located in above-mentioned hollow stem chamber slidably along front frame 2 length directions, the first spring 82 is located in this hollow stem chamber for providing dead bolt 81 along its direction of slip elastic-restoring force, on dead bolt 81, there is inclined-plane, when front frame 2 rotates and when the top of front frame 2 draws close gradually with the rear portion of Connection Block 6 gradually relative to Connection Block 6 around the shaft, first conflict on Connection Block 6 in inclined-plane on dead bolt 81, continue rotation front frame 2, dead bolt 81 is first retracted in the hollow stem chamber of front frame 2, rotate while aiming at the notch of locked groove 83 to the oral area in its hollow stem chamber until front frame 2, under the effect of the first spring 82, dead bolt 81 inserts in locked groove 83, front frame 2 just locks with Connection Block 6 mutually like this.
in locked groove 83, be also provided with and separate lock slide 9, the second spring 10 and start slide block 11, separate lock slide 9 and be located at slidably in locked groove 83 along the direction of inserting locked groove 83 perpendicular to dead bolt 81, the second spring 10 is connected to locked groove 83 cell walls and separates between lock slide 9 and separate the elastic-restoring force of lock slide 9 along its direction of slip for providing.Separate on lock slide 9 and there is lozenges, inclined-plane on this lozenges and dead bolt 81 can cooperatively interact, in the time that solution lock slide 9 slides and pushes dead bolt 81 in locked groove 83, can make dead bolt 81 return in the hollow stem chamber of front frame 2 and make dead bolt 81 depart from locked groove 83, and then realizing the release of the second locking piece 8.Starting 11 of slide blocks drives dead bolt 81 to depart from locked groove 83 for driving solution lock slide 9 to slide, here, start between slide block 11 and the electric bell of the first locking piece 7 and be connected with trailing cable (not shown), can make like this first locking piece 7 and the second locking piece 8 linkage of unlockings and arrange, in the time of Folding trolley, only need like this one of them locking piece release can carry out the release of go-cart and fold.
one end of trailing cable is fixedly connected on and starts on slide block 11, and its other end is fixed on an electric bell cover in two counterrotating electric bell covers of electric bell, or is fixed on that on electric bell, other can produce on the parts of displacement in the time of electric bell release.Like this in the time of electric bell release, trailing cable is connected to the end under tension on electric bell and pulls and start slide block 11, starts slide block 11 and drives solution lock slide 9 to slide and the synchronizing unlocking that orders about dead bolt 81 and exit locked groove 83 and realize the second locking piece 8 again.
like this, upon deployment, as shown in Figure 1, the first locking piece 7 and the second locking piece 8 are all in the lock state vehicle frame, the upper push-rod of push rod 1 102 and lower push-rod 101 relative deformations, and the top of front frame 2 is locked on Connection Block 6 and Connection Block 6 is fixing relatively.When needs are during by vehicle frame folding, shown in Figure 4, first upper push-rod 102 is reclaimed along lower push-rod 101, make the contraction in length of push rod 1, the electric bell release of push rod 1, the first locking piece 7 of then turning over, in electric bell releasing process, pull trailing cable, trailing cable is pulled start slide block 11 and make to separate lock slide 9 and drive dead bolt 81 to recess locked groove 83, the second locking piece 8 synchronizing unlockings, now front frame 2 can rotate around the shaft relative to Connection Block 6.Turned in the bottom of front frame 2, front frame 2, after poppet 3 and push rod 1 are drawn close mutually, be finally folded into state as shown in Figure 4.
in the time that needs launch vehicle frame, push rod 1 is carried and upset forward, until the relative after poppet 3 of push rod 1 turn to electric bell when locking of the first locking piece 7, trailing cable is released, front frame 2 is rotated its top is turned over gradually afterwards around the rotate rotating shaft that is connected of itself and Connection Block 6, until dead bolt 81 reinserts in locked groove 83, front frame 2 and Connection Block 6 are locked mutually, finally the upper push-rod on push rod 1 102 is pulled out from lower push-rod 101, go-cart is expanded to the deployed condition shown in Fig. 1 again.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
