Abstract
The invention discloses a portable type foldable cart which comprises a chassis, a chassis foldable connecting rod, a foldable handle, a flexible pull rod, a universal wheel, a driven wheel, a self-locking spring slide block and a rivet. The cart can be folded in order to take and store so the occupied space is small. The cart can be unfolded so as to carry bigger and heavier goods. Compared with the prior art, the cart is portable, has simple operation and has stable structure. The foldable structure is optimized and improved, so the problems that the cart is inconvenient to take and occupies huge space in the daily use, the goods can easily fall off because the foldable mechanism is not firm enough, and the rod type wheel axle is easy to deform so the drag is strenuous are solved, and the cart is light, portable and firm.

Technical field
The invention belongs to the daily living article field, relate to shopping and travel items carrying utensil, be specifically related to a kind of portable type foldable cart.
Technical background
Hand buggy is the utensil that is commonly used to load product and luggage at present people when doing shopping and travelling outdoors, and because of it can bring convenience and save strength for the bearer at carrying article and luggage, therefore a lot of people carry hand barrow when trip.
Yet the problem of hand buggy product existence now: it is big to take up room, and is not easy to carry, and fold mechanism firmly causes the article landing inadequately, and the dilatory effort that deformation causes, the structural instability of vehicle frame easily take place the rod-type wheel shaft.
Summary of the invention
The object of the present invention is to provide a kind of hand buggy easy to carry, simple to operate, constitutionally stable.The present invention folds handle by adopting Foldable frame, and telescopic lever has solved the big problem that takes up room, when carrying and deposit, hand buggy can be folded up, only take very little space, trailer can be launched during use, delivery larger volume and heavier article.The self-locking spring slide block has solved the hand buggy structure problem of unstable, guarantees its stability in use like this.
The technical scheme that achieves the above object is: a kind of portable type foldable cart, and by underframe [1], telescopic lever [2], cardan wheel [3], flower wheel [4], bearing [5], bogie truck [6], folding handle [7], folding connecting rod [8], locating rivet [9], self-locking spring slide block [10] constitutes; It is characterized in that: the both sides of described underframe [1] are connected with folding connecting rod [8] by locating rivet [9]; Described telescopic lever [2] passes through bolted connection with underframe [1], and can be connected shaft centerline h rotation with underframe [1] around telescopic lever [2]; Described cardan wheel [3] is connected with underframe [1] by bogie truck [6]; Described flower wheel [4] is connected with underframe [1] by bearing [5]; Described folding handle [7] is connected by rivet with telescopic lever [2]; Two branch bar outer ends of described folding connecting rod [8] can be rotated around folding connecting rod revolute pair line of centers j, and two branch bar the inners can be rotated around the rotary centerline k of underframe [1] with folding connecting rod [8] bonded assembly locating rivet [9].
Described underframe [1] is provided with self-locking spring slide block [10] with the junction of folding connecting rod [8], and described folding connecting rod [8] is when locating rivet [9] rotary centerline k half-twist, and self-locking spring slide block [10] ejects, locking folding connecting rod [8].
Described telescopic lever [2] is 120 ° around the maximum angle that underframe [1] connects axis h rotation.
Beneficial effect of the present invention:
The present invention is by carrying out system optimization and improvement to folding structure, solved the problem of the dilatory effort that trailer existing big, fold mechanism of being not easy to carry, take up space in daily people use firmly causes article landing, the rod-type wheel shaft easily deformation to take place being caused inadequately, make trailer lighter and handier, portable, solid, the outstanding design thought that people-oriented.

The specific embodiment
Further the structure and the embodiment of a kind of portable type foldable cart of the present invention are elaborated below in conjunction with accompanying drawing.
Embodiment 1.
The present invention includes underframe [1], telescopic lever [2], cardan wheel [3], flower wheel [4], bearing [5], bogie truck [6], folding handle [7], folding connecting rod [8], locating rivet [9], self-locking spring slide block [10]; The both sides of described underframe [1] are connected with folding connecting rod [8] by locating rivet [9]; Telescopic lever [2] passes through bolted connection with underframe [1], and cardan wheel [3] is connected with underframe [1] by bogie truck [6], and flower wheel [4] is connected with underframe by bearing [5]; Described folding handle [7] passes through rivet with telescopic lever [2]; Described telescopic lever [7] structure comprises that one section female pipe is connected with two cross-talk sleeve pipes and by locating groove.
Underframe of the present invention [1] is provided with self-locking spring slide block [10] with the junction of folding connecting rod [8], folding connecting rod [8] is around locating rivet [9] rotary centerline k half-twist, self-locking spring slide block this moment [10] limits folding connecting rod [8] pinning to it and rotates around locating rivet [9] rotary centerline k, the distance of fixed frame [1] both sides plays the effect of stable underframe [1] structure; Underframe [1] has a circular port in bogie truck [6] top, and bogie truck [6] round pin can any direction rotation in this circular hole.
Telescopic lever [2] is connected shaft centerline h rotation around telescopic lever with underframe, but the maximum anglec of rotation that is become with underframe [1] is 120 °, and is more laborsaving, comfortable in the time of can making the user dilatory; Have the classification locating groove in mother's pipe of telescopic lever [2] and the two cross-talk sleeve pipes, can make the length of pull bar carry out the classification adjusting, satisfy the user's of different heights needs according to user's height.
The most inboard sub-sleeve pipe of rivet and telescopic lever [2] that passes through of folding handle of the present invention [7] is fixed, can in 0 °～90 °, rotate along rivet, it in the time of 0 ° folded state, it in the time of 90 ° deployed condition, and the effect that the circular arc of folding handle [7] terminal excessively blocks certainly to the sub-internal surface of sleeve pipe that the design of face can be played and telescopic lever [2] is the most inboard under deployed condition has limited folding handle [7] and has rotated around rivet.
Folding connecting rod of the present invention [8] can only just can not rotate after folding connecting rod launches laterally along folding connecting rod revolute pair line of centers j rotation again, reaches the distance of fixed frame [1] both sides.
Other embodiment:
Portable type foldable cart of the present invention, also can be different with purposes according to the carrying weight of goods, be designed to the different product of intensity, for example between warehousing district and sales territory, carry out portage and can adopt comparatively solid firm structure, can adopt lighter structure as carrying with hand buggy.
