In the present embodiment, the extension line of the length direction of the push rod 5 of children trolley intersects with the extension line of the length direction of front-wheel support 3.
This utility model front-wheel support 3 includes that bottom is provided with the front-wheel support body 31 of front component 1 and is fixedly installed on the adapter sleeve 32 of front-wheel support body 31 upper end, and rear wheel support 4 is rotationally connected with adapter sleeve 32, and push rod 5 can slidably pass through adapter sleeve 32.Specifically, push rod 5 includes the upper push-rod 51 that the lower push-rod 52 that can slidably pass through adapter sleeve 32 and the length direction along lower push-rod 52 are slidably arranged on lower push-rod 52, and pull bar 6 is rotationally connected with the bottom of lower push-rod 52.
When trolley rack is in deployed condition, the place of being rotationally connected of rear wheel support 4 and adapter sleeve 32 is positioned at the top being rotationally connected place of lower push-rod 52 and pull bar 6.
Rear wheel support 4 is paralleled with the rotational axis line of rear wheel support 4 with rotational axis line and the pull bar 6 of lower push-rod 52 with rotational axis line, the pull bar 6 of adapter sleeve 32.
Specifically, the upper and lower end at lower push-rod 52 is respectively arranged with the first limiting section 7 and the second limiting section 8 preventing adapter sleeve 32 from departing from lower push-rod 52.
Lower push-rod 52 has hollow cavity, and upper push-rod 51 is slidably arranged in the interior intracavity of lower push-rod 52.
When the trolley rack of this utility model go-cart folds, lower push-rod 52 slides from the top of the downward push rod in the bottom of lower push-rod 52 52 along adapter sleeve 32 slide downward, adapter sleeve 32 relative to lower push-rod 52, and rear wheel support 4 downward push rod 52 under the drive of pull bar 6 is drawn close.
The rear wheel support 4 of this utility model go-cart is arc knee.Specifically, rear wheel support 4 includes from front to back and tilts from top to bottom the first paragraph 41 of extension and the rearward end from first paragraph 41 bends the second segment 42 downwardly extended, there is between first paragraph 41 and second segment 42 angle more than 90 °, adapter sleeve 32 is rotationally connected with the leading section of first paragraph 41, and pull bar 6 is rotationally connected with second segment 42.
Rear wheel support 4 also includes the extension 43 extended forward from the leading section of first paragraph 41 along the length direction of first paragraph 41.In the particular embodiment, the seat bar that first paragraph 41 and extension 43 can collectively form children trolley uses, it is also possible to the section of will extend over 43 uses as the seat bar of children trolley.
The trolley rack of this utility model go-cart also includes the connecting rod being connected between the side stand of both sides.Specifically, connecting rod includes second connecting rod 10 that first connecting rod 9 that both ends are connected respectively, both ends are connected with both sides rear wheel support respectively and the third connecting rod 11 that both ends are connected with both sides upper push-rod 51 respectively with both sides front-wheel support body 31.
Locking mechanism of the present utility model can be to include the first locking mechanism upper push-rod 51 and lower push-rod 52 locked and the second locking mechanism lower push-rod 52 and adapter sleeve 32 locked, can also be the locking mechanism that upper push-rod 51, lower push-rod 52 and adapter sleeve 32 are locked simultaneously, or the locking mechanism of other modes.
When the trolley rack of this utility model go-cart is in deployed condition, the lower end part of upper push-rod 51 is in the top of lower push-rod 52, adapter sleeve 32 is positioned at the bottom of lower push-rod 52, and the place of being rotationally connected of rear wheel support 4 and adapter sleeve 32 is positioned at the top being rotationally connected place of lower push-rod 52 and pull bar 6;When trolley rack is in folded state, the lower end part of upper push-rod 51 is in the bottom of lower push-rod 52, and adapter sleeve 32 is positioned at the top of lower push-rod 52, and the downward push rod 52 of rear wheel support 4 is drawn close.
The folding of this utility model children trolley and spreading principle:
As shown in Fig. 1 ~ 4, children trolley is in deployed condition, and the lower end part of upper push-rod 51 is in the top of lower push-rod 52, and adapter sleeve 32 is positioned at the bottom of lower push-rod 52, and trolley rack is locked in deployed condition by locking mechanism.When go-cart being folded, unlock locking mechanism, push down on upper push-rod 51, lower push-rod 52 is along adapter sleeve 32 slide downward, adapter sleeve 32 slides from the top of the downward push rod in the bottom of lower push-rod 52 52 relative to lower push-rod 52, the leading section of pull bar 6 moves downward due to moving downward of lower push-rod 52, and then pull the downward push rod 52 of rear wheel support 4 to draw close, continuing to push down on upper push-rod 51 makes the bottom of upper push-rod 51 slide to the bottom of lower push-rod 52, complete to fold, go-cart after folding completely sees Fig. 5 ~ 6, go-cart after folding, the lower end part of upper push-rod 51 is in the bottom of lower push-rod 52, adapter sleeve 32 is positioned at the top of lower push-rod 52, the downward push rod 51 of rear wheel support 4 is drawn close, car load folding volume is little.
When go-cart being launched, such as Fig. 7 ~ 8, pull up upper push-rod 51, lower push-rod 52 is driven to move upward along adapter sleeve 32, adapter sleeve 32 relative to lower push-rod 52 from the lower slide of the downward push rod in the top of lower push-rod 52 52, the leading section of pull bar 6 moves upward due to moving upward of lower push-rod 52, and then pull rear wheel support 4 to launch to the direction away from lower push-rod 52, pulling up on upper push-rod 51 makes the bottom of upper push-rod 51 slide to the top of lower push-rod 52, complete the expansion of trolley rack, trolley rack is locked in deployed condition by recycling locking mechanism, expansion completes, as shown in Figure 1 and 2.
When this utility model go-cart folds, can first by upper push-rod 51 along lower push-rod 52 slide downward, then by upper push-rod 51 and lower push-rod 52 together along adapter sleeve 32 slide downward;Can also first by lower push-rod 52 along adapter sleeve 32 slide downward, then by upper push-rod 51 along lower push-rod 52 slide downward.
In sum, children trolley of the present utility model folds and launches flexible operation, convenience, easily uses, and volume after folding is little, is convenient for carrying.
Go-cart of the present utility model can be common go-cart, it is also possible to be the go-cart opened of automatic folding, or other kinds of go-cart.
