Utility model content
The purpose of this utility model is to provide a kind of convenience spacing to folding rod, is convenient for changing fragile part, and structural strength stow-away arm rest firmly.
To achieve these goals, the technical solution of the utility model is: a kind of stow-away arm rest, comprise two folding rods, backstay and U-shaped connector, one end of two folding rods is hinged by U-shaped connector and backstay respectively, also comprise fixed bar, alignment pin and flexible connecting member, the other end of two folding rods is hinged by U-shaped connector and fixed bar respectively, alignment pin is by flexible connecting member and folding rod or U-shaped connector or fixed bar load, and one of them folding rod is provided with the first dowel hole, the U-shaped connector that one folding rod is corresponding is provided with the second pin-and-hole, described alignment pin is provided with the radial blind holes with reducing, in radial blind holes, be provided with back-moving spring and spacing ball, one end of back-moving spring and the bottom surface of radial blind holes offset, the other end and spacing ball offset, and spacing ball is the periphery of outstanding alignment pin partly, when folding rod needs are spacing, alignment pin inserts the second pin-and-hole and the first dowel hole, and spacing by spacing ball.
On described fixed bar, be also provided with two inserted links.
On described backstay, be also provided with wooden armrest.
Also have installing ring, be also provided with radially installing hole on described alignment pin, installing ring is sleeved on radially on installing hole, and with flexible connecting member load.
Described flexible connecting member is connection cord.
Adopt after said structure, the other end of two folding rods is hinged by U-shaped connector and fixed bar respectively, therefore fixed bar can be fixedly connected with folding bed body, improved structural strength of the present utility model, when folding rod needs are spacing, as long as the second pin-and-hole over against U-shaped connector by the first dowel hole of folding rod, alignment pin is inserted to the second pin-and-hole and the first dowel hole, be used for spacing to folding rod, when alignment pin inserts, spacing ball and folding rod on alignment pin clamp, be used for limiting moving axially of alignment pin, therefore the utility model is to the spacing convenience of folding rod, and need only and change alignment pin after spacing ball damage, it is convenient to change.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the cutaway view of alignment pin in Fig. 1.
The specific embodiment
The embodiment providing below in conjunction with accompanying drawing, is described in further detail the utility model.
As Fig. 1, 2, shown in 3, a kind of stow-away arm rest, comprise two folding rods 1, backstay 2 and U-shaped connector 4, one end of two folding rods 1 is hinged with backstay 2 by U-shaped connector 4 respectively, also comprise fixed bar 3, alignment pin 5 and flexible connecting member 6, the other end of two folding rods 1 is hinged with fixed bar 3 by U-shaped connector 4 respectively, alignment pin 5 is by flexible connecting member 6 and U-shaped connector 4 loads, can certainly with fixed bar 3 and folding rod 1 load, all meet instructions for use, and one of them folding rod 1 is provided with the first dowel hole 1-1, the U-shaped connector 4 of this folding rod 1 correspondence is provided with the second pin-and-hole 4-1, described alignment pin 5 is provided with the radial blind holes 5-1 with reducing, in radial blind holes 5-1, be provided with back-moving spring 5-2 and spacing ball 5-3, the bottom surface of one end of back-moving spring 5-2 and radial blind holes 5-1 offsets, the other end and spacing ball 5-3 offset, and spacing ball 5-3 is the periphery of outstanding alignment pin 5 partly, when folding rod 1 needs when spacing, alignment pin 5 inserts the second pin-and-hole 4-1 and the first dowel hole 1-1, and spacing by spacing ball 5-3.
Shown in Fig. 1,2, on described fixed bar 3, be also provided with two inserted link 3-1, inserted link 3-1 can be inserted in the installing hole of folding bed body and weld, and the utility model and folding bed is fixed more firm.
