The invention provides a jig frame structure for truss assembling, and meanwhile relates to a method for assembling a truss with the jig frame structure. A left ground rack (1) and a right ground rack (2) of the jig frame structure are provided with a plurality of left vertical sliding rods (3) and a plurality of right vertical sliding rods (4) respectively, the left vertical sliding rods (3) and the right vertical sliding rods (4) can freely slide along the left ground rack (1) and the right ground rack (2) respectively, each left vertical sliding rod (3) and the corresponding right vertical sliding rod (4) are sleeved with a plurality of transverse carrying rods (6) used for supporting truss main tubes (5) of the truss (27), the two ends of each transverse carrying rod (6) are provided with structures capable of vertically moving along the left vertical sliding rods (3) and the right vertical sliding rods (4) respectively. By means of the jig frame structure and the method for assembling the truss, the truss with any size, any height, any width and any curvature can be assembled; in the truss assembling process, the accuracy of the truss can be guaranteed, and the operation risk and the operation difficulty are reduced.

A front wheel foldable device for a golf cart includes a main body, a wheel frame, a positioning member, a sleeve, a stop member, and an elastic member. Thus, the wheel frame is pulled outwardly relative to the main body so that the locking portions of the positioning member are moved to detach from the locking grooves of the main body respectively. Then, the wheel frame is rotated through ninety (90) degrees and is released, so that the post of the wheel frame is retracted into the main body by a restoring force of the elastic member, the locking portions are locked in the locking grooves respectively, the front wheel is turned from an upright state to a horizontal state, and the front wheel is parallel with and rested on the cart frame when the cart frame is folded.

The invention relates to an environment-friendly cushioning good-enwrapping performance popcorn-like bridging shoe and a making technology thereof. An upper of the bridged shoe consists of an inner boot and a vamp; the inner boot is formed by integrally connecting an inner lining, and an inner cushion formed through once injection moulding; the neckline of the inner boot is fixedly connected with the neckline of the vamp; the lower edge of the vamp stretches to the bottom surface of the inner cushion and is fixedly connected with the inner cushion; the upper and a sole are integrally connected through a PU bridging layer; the PU bridging layer enwraps the lower edge of the vamp; the sole is a popcorn-like sole made by mixing PU and TPU popcorn granules. Compared with the conventional shoemaking technology, the making technology provided by the invention has the advantages as follows: the making technology is relatively simple, a sole laying process and an insole assembling process can be omitted, the popcorn-like sole and the bridging layer are bonded more firmly, and the shock absorbing performance is better; through the inner boot designed and made according to a foot shape, the upper and the sole can enwrap a foot well; by increasing the using amount of a PU material, the environment-friendly cushioning good-enwrapping performance popcorn-like bridging shoe is higher in soluble ratio and more environment-friendly.
