Description
Technical field
The utility model relates to a kind of children trolley vehicle frame and receives and structure.
Background technology
Children trolley is baby's favorite doll carriage stroll vehicle, requisite when mother goes shopping with baby especially, and its use is very universal.But existing children trolley vehicle frame is received and structure is relatively complicated, and folding process is loaded down with trivial details, uses inconvenience.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of children trolley vehicle frame and receives and structure, simple for structure, easy to operate.
The utility model in order to the technical scheme solving its technical matters and adopt is: a kind of children trolley vehicle frame is received and structure, comprise push rod, hauling rope, large joint, sliding shoe, lower adaptor, front foot pipe, lock pin and elastic component, the upper end of described front foot pipe is fixedly connected with the bottom of described lower adaptor; Described large joint is hollow structure, and described push rod bottom to be inserted in this upper end, large joint and fixing; Two relative sides of the bottom in described large joint form two and rotate holding parts, the upper end of described lower adaptor is formed and rotates fixed part, and this rotation fixed part to be placed in two these rotation holding parts and to be rotatably connected by turning cylinder in the position near described lower adaptor; On the position in described large joint, a position-limited trough is also provided with at the rotation fixed part of described lower adaptor; The both ends of described lock pin are fixed on described sliding shoe, this sliding shoe is placed through in the hollow structure in described large joint, described hauling rope one end and this sliding shoe upper end is connected, the other end of this hauling rope is placed through and stretches out this push rod after in described push rod and formed outward and unlock end; Form hollow structure in the middle part of described sliding shoe, described elastic component is accommodating in it, and this elastic component upper end is fixedly connected with large joint, and the lower end of this elastic component is springy to be pushed against on this sliding shoe; Described lock pin can be placed in described position-limited trough and make described lower adaptor and large joint spline under the elastic force effect of described elastic component.
As further improvement of the utility model, described elastic component is retracing spring.
As further improvement of the utility model, described rotation fixed part and rotation holding part are circle.
The beneficial effects of the utility model are: this children trolley vehicle frame is received and structure adopts hauling rope and lock pin as the locking and unlocking element, simple for structure, easy to operate, quick, has saved manufacturing cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model decomposition texture schematic diagram.
By reference to the accompanying drawings, make the following instructions:
1---push rod 2---hauling rope
3---large joint 4---sliding shoe
5---lower adaptor 6---front foot pipe
7---lock pin 8---elastic component
9---turning cylinder 31---rotates holding part
51---rotating fixed part 511---position-limited trough
Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But protection domain of the present utility model is not limited to following embodiment, the simple equivalence namely in every case done with the utility model claim and description changes and modifies, and all still belongs within the utility model patent covering scope.
As shown in Figure 1, 2, a kind of children trolley vehicle frame is received and structure, and comprise push rod 1, hauling rope 2, large joint 3, sliding shoe 4, lower adaptor 5, front foot pipe 6, lock pin 7 and elastic component 8, the upper end of described front foot pipe is fixedly connected with the bottom of described lower adaptor; Described large joint is hollow structure, and described push rod bottom to be inserted in this upper end, large joint and fixing; Two relative sides of the bottom in described large joint form two and rotate holding parts 31, the upper end of described lower adaptor is formed and rotates fixed part 51, and this rotation fixed part to be placed in two these rotation holding parts and to be rotatably connected by turning cylinder 9 in the position near described lower adaptor; On the position in described large joint, a position-limited trough 511 is also provided with at the rotation fixed part of described lower adaptor; The both ends of described lock pin are fixed on described sliding shoe, this sliding shoe is placed through in the hollow structure in described large joint, described hauling rope one end and this sliding shoe upper end is connected, the other end of this hauling rope is placed through and stretches out this push rod after in described push rod and formed outward and unlock end; Form hollow structure in the middle part of described sliding shoe, described elastic component is accommodating in it, and this elastic component upper end is fixedly connected with large joint, and the lower end of this elastic component is springy to be pushed against on this sliding shoe; Described lock pin can be placed in described position-limited trough and make described lower adaptor and large joint spline under the elastic force effect of described elastic component.Preferably, described elastic component is retracing spring, and described rotation fixed part and rotation holding part are circle.
During use, by the other end of pulling traction rope namely unlock end band move sliding shoe and on lock pin to away from lower adaptor one end motion, even if lock pin departs from the position-limited trough in lower adaptor, thus realize the unblock in lower adaptor and large joint, now can realize the rotation of large joint and lower adaptor, receipts and the action of vehicle frame can be carried out.And when vehicle frame is opened, due to the elastic force effect of elastic component, promoting sliding shoe makes the lock pin on it snap in position-limited trough, thus achieve the locking in lower adaptor and large joint, now cannot rotate lower adaptor and large joint, go-cart can normally use.As can be seen here, this children trolley vehicle frame receipts and structure are very succinct, receive with operation is very easy, fast, facilitate the use of people greatly, because structure is more succinct, decrease manufacturing cost.
