The trailing flank on described side arm top is provided with 2 clamps extended back, and the leading section of this after-frame is hinged between these 2 clamps by the 3rd rotating shaft, and has one the 3rd alignment pin through the leading section of these 2 clamps with this after-frame.
Described after-frame comprises the first after-frame, the second after-frame and connector, this connector includes 2 the first connecting plates extended all forward and 2 the second connecting plates all extended back, the rearward end of this first after-frame is hinged between these 2 first connecting plates by the first rotating shaft, and have one first alignment pin through these 2 first connecting plates and this first after-frame, the leading section of this second after-frame is hinged between these 2 second connecting plates by the second rotating shaft, and has one second alignment pin through these 2 second connecting plates and this second after-frame.
Described service creeper comprises the front service creeper be fixed on this first after-frame and the rear service creeper be fixed on this second after-frame.
Described after-frame is hinged on a lasso, and this lasso is enclosed within this side arm, and this lasso is installed with heightens pin, and this side arm is provided with to be heightened at least 2 that pin passes heighten hole for this.
The present invention is compared to the prior art advantageously: be convenient to storage and carrying.The after-frame of collapsible board for lying on back of the present invention can fold relative to side arm, and after-frame is also collapsible, and the front end of after-frame can have different height relative to side arm.Like this, when not using, taking up room of board for lying on back can be effectively reduced by folding mode, thus being convenient to storage and transport.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the collapsible board for lying on back front view in use of embodiments of the invention;
Fig. 2 is the schematic perspective view that side arm of the present invention is connected with after-frame;
Fig. 3 is the schematic perspective view that the first after-frame of the present invention is connected with the second after-frame;
Fig. 4 is the schematic perspective view that after-frame of the present invention is connected with side arm;
Fig. 5 is the front view of collapsible board for lying on back when folding of embodiments of the invention.
Detailed description of the invention
Embodiment, as shown in Figure 1: collapsible board for lying on back, comprises the side arm 11 and after-frame 12 that link together, and the top of this side arm 11 is provided with the first strut 30, the front portion of this after-frame 12 is provided with the second strut 20, and meanwhile, the middle part of this after-frame 12 is provided with service creeper 70.That is, in use, this first strut 30 is equivalent to common pin raker, and this second strut 20 is equivalent to common support bar.
Further say, shown in composition graphs 5, the front end of this after-frame 12 is hinged on this side arm 11, and this after-frame 12 is collapsible.Certainly, positioner must be had between the leading section of this after-frame 12 and this side arm 11.Like this, this after-frame 12 can fold relative to this side arm 11, in conjunction with the after-frame 12 that can fold, enables this board for lying on back have less volume, thus is convenient to transport and storage.
Continue to optimize:
Shown in composition graphs 2, the trailing flank on this side arm 11 top is provided with 2 clamps 111 extended back, and these 2 clamps 111 are parallel to each other.The leading section of this after-frame 12 is hinged between these 2 clamps 111 by the 3rd rotating shaft 61, and has one the 3rd alignment pin 62 through the leading section of these 2 clamps 111 with this after-frame 12.That is, only need the 3rd alignment pin 62 to extract, can facilitate and realize this after-frame 12 fast and fold relative to this side arm 11.
Shown in composition graphs 3, this after-frame 12 comprises the first after-frame 121, second after-frame 122 and connector 123.This connector 123 includes 2 the first connecting plates 1231 extended all forward and 2 the second connecting plates 1232 all extended back, and these 2 the first connecting plates 1231 and these 2 the second connecting plates 1232 are obviously all in vertical.The rearward end of this first after-frame 121 is hinged between these 2 the first connecting plates 1231 by the first rotating shaft 41, and has one first alignment pin 42 through these 2 first connecting plates 1231 and these first after-frames 121.Obviously, on these 2 the first connecting plates 1231, this first after-frame 121 must be provided with the through hole passed for this first alignment pin 42.That is, only need to extract this first alignment pin 42 and can realize the fast folding of this first after-frame 121 relative to this connector 123 easily.The leading section of this second after-frame 122 is hinged between these 2 the second connecting plates 1232 by the second rotating shaft 51, and has one second alignment pin 52 through these 2 second connecting plates 1232 and these second after-frames 122.Equally, on these 2 the second connecting plates 1232, this second after-frame 122 must be provided with the through hole passed for this second alignment pin 52.That is, only need to extract this second alignment pin 52 and can realize the fast folding of this second after-frame 122 relative to this connector 123 easily.More excellent, this service creeper 70 comprises the front service creeper 71 be fixed on this first after-frame 121 and the rear service creeper 72 be fixed on this second after-frame 122.Like this, board for lying on back is made to have more rational structure.
Shown in composition graphs 4, this after-frame 12 is hinged on a lasso 80, and this lasso 80 is enclosed within this side arm 11, and this lasso 80 is installed with heightens pin 81, and this side arm 11 is provided with to be heightened at least 2 that pin 81 passes heighten hole 112 for this.That is, this is heightened pin 81 to be through and different to heighten in hole 112, namely the elevation angle of this service creeper 70 adjustable is so that provide different exercise intensities, and is convenient to coordinate the folding of board for lying on back.Now, these 2 clamps 111 are arranged on this lasso 80.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
