Accompanying drawing explanation
Fig. 1 is the collapsible body-building board for lying on back of the utility model deployed condition structural representation;
Fig. 2 is shaft portion structural representation in the collapsible body-building board for lying on back of the utility model;
Fig. 3 is the collapsible body-building board for lying on back of the utility model folded state structural representation.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The structure of a kind of collapsible body-building board for lying on back of the present utility model is as Fig. 1, shown in Fig. 2 and Fig. 3, comprise vertical frame 2 and crossbearer, described vertical frame 2 is connected with described crossbearer, described crossbearer is provided with service creeper 1, it is characterized in that: described crossbearer is divided into crossbearer 31 and lower cross frame 32, it between upper crossbearer 31 and lower cross frame 32, is telescopic sleeve pipe connection, described service creeper 1 comprises service creeper 10 and lower service creeper 11, described upper service creeper 10 is arranged on described upper crossbearer 31, described lower service creeper 11 is arranged on described lower cross frame 32, described lower service creeper 11 is connected by connecting rod 4 with described lower cross frame 32, described connecting rod 4 is rotatably connected with described lower service creeper 11, described connecting rod 4 is rotatably connected with described lower cross frame 32.
When described folding body-building board for lying on back launches, under the effect of the linkage forming at lower service creeper 11, connecting rod 4, lower cross frame 32, described lower service creeper 11 is close on described lower cross frame 32.When described folding body-building board for lying on back is folding, under the effect of the linkage forming at lower service creeper 11, connecting rod 4, lower cross frame 32, described lower service creeper 11 is parallel and at regular intervals with lower cross frame 32, now can make crossbearer 31 and lower cross frame 32 shrink, and service creeper 10 is inserted in the spacing of lower baffle plate 11 and lower cross frame 32, thereby realize the folding of service creeper 1.
Wherein, between described crossbearer and described vertical frame 2, for being rotatably connected, described vertical frame 2 comprises vertical frame 21 and lower vertical frame 21, between described upper vertical frame 21 and described lower vertical frame 22 for telescopic sleeve pipe is connected.By the rotation of described crossbearer and described vertical frame 2, can realize the folding of described crossbearer and described vertical frame 2, described upper vertical frame 21 is connected and can makes described vertical frame 2 realize folder function with telescopic sleeve pipe between described lower vertical frame 22, further reduces the volume of the utility model after folding.
For fixing upper crossbearer 31 and lower cross frame 32, between described upper crossbearer 31 and described lower cross frame 32, be provided with clamp nut 33, described clamp nut 33 is for fixing between upper crossbearer 31 and described lower cross frame 32.
Consider the utility model deployed condition accuracy of service creeper location at present, described upper crossbearer 31 is provided with the first installation position 5, and described the first installation position 5 can be used for the location of described lower service creeper 11.
In addition, described lower cross frame 32 is provided with the projection for stopping that described connecting rod 4 rotates, and described lower service creeper 11 is provided with the connecting rod installation position 111 to lower convexity.The arranging of installation position 111 can reduce lower service creeper 11 while being close to lower cross frame 32, and the angle of connecting rod 4 and lower cross frame 32, is optimized in terms of mechanics.
The beneficial effects of the utility model: can fold, reduced volume, is convenient for carrying and transports, and has in addition sound construction, the advantage that security is good.
