Description

The turnover bed of a kind of back cushion

Technical field

The utility model belongs to furniture and makes the field, is specifically related to the turnover bed of a kind of back cushion.

Background technology

The doss that family is commonly used mainly is made up of bedstead and headpiece, and usually, headpiece is all fixed.The back cushion of headpiece can only adopt single structure, and, bamboo matter wooden such as adopting, leather coats or a kind of in coating of cloth art.The bed of this structure, the back cushion pattern is unalterable, and is comparatively stiff, and material can not overturn according to seasonal variations, adopts woodenly or bamboo matter, and summer is comparatively nice and cool, but back can be very ice-cold above leaning against when using winter; Adopt leather to coat or cloth art coats, winter is against comfortable, but to summer, can feel very airtight.

Summary of the invention

The utility model has designed the turnover bed of a kind of simple and reasonable, easy to operate back cushion at the problem that present doss exists, and can freely select suitable material according to seasonal variations, uses as snug as a bug in a rug.

The purpose of this utility model is achieved in that the turnover bed of a kind of back cushion, comprise bedstead, headpiece, it is characterized in that: described headpiece comprises both sides vertical beam and middle back cushion, and back cushion two middle side parts rotatably are hinged on the vertical beam, are provided with positioner between back cushion and the vertical beam.

Described positioner comprises with the pin joint and is located at the locating hole of back cushion side top and bottom and is located at the latch that is connected with locating hole on the curb girder for the center symmetry, when locating hole is inserted in the end of latch, back cushion is carried out angle orientation.

Described latch adopts press-button structure control, comprise holder, latch, back-moving spring, power transmission shaft, elasticity bayonet lock and button, be provided with axis hole in the holder, latch, back-moving spring and power transmission shaft are installed in the axis hole of holder, wherein power transmission shaft and latch contact jaw have a conical head, offer recess on the conical head, the elasticity bayonet lock is installed in the fixed seating on the inwall at conical head place, when latch stretched out or withdraws, elasticity bayonet lock front end was resisted against the rear end face of conical head respectively or is positioned at the front end face of conical head.

Described latch adopts the screw knob structure control, comprises being installed in the metal tube with internal thread on the curb girder and being threaded in screw rod on the metal tube, and spiro rod rear end portion has knob.

Good effect of the present utility model: the back cushion of headpiece rotatably is hinged on the vertical beam of both sides, be provided with positioner between back cushion and the vertical beam, adopt the turnover bed of back cushion of this structure, the back cushion front end face just can adopt different materials with rear end face, adopt leather or cloth art to coat such as front end face, rear end face directly adopts natural wooden or bamboo material manufacturing, the user can freely select according to seasonal variations, in addition, different patterns also can be designed in the back cushion two sides, makes bed have the back cushion of two kinds of different-styles.

The specific embodiment

Be described in further detail below in conjunction with the specific embodiment of accompanying drawing the turnover bed of the utility model back cushion.

The specific embodiment: as shown in Figure 1-Figure 3, the turnover bed of back cushion described in the utility model mainly is made up of bedstead 1 and headpiece 2.Headpiece 2 comprises both sides vertical beam 3 and

middle back cushion

4,4 liang of middle side parts of back cushion rotatably are hinged on the vertical beam 3, be provided with positioner between vertical beam 3 and the back cushion 4, mainly form by being located at the locating hole 5 on the back cushion 4 and being located at the latch 6 that is connected with locating hole 5 on the vertical beam 3, back cushion 4 both sides are equipped with two locating holes 5, be the top and bottom that the center symmetry is located at back cushion 4 sides with pin joint A respectively, when locating hole 5 is inserted in the end of latch 6, back cushion 4 carried out angle orientation.Wherein latch 6 can adopt the press-button structure control of handled easily, as Fig. 2, Fig. 3, shown in Figure 4, mainly by latch 6, holder 7, back-moving spring 8, power transmission shaft 9, elasticity bayonet lock 10 and button 11 are formed, holder 7 is installed on the vertical beam 3, in be provided with axis hole, latch 6, back-moving spring 8 and power transmission shaft 9 are installed in the axis hole of holder 7, power transmission shaft 7 has a conical head 70 with latch 6 contact jaws, offer recess 71 on the conical head 70, elasticity bayonet lock 10 is installed on the inwall that holder 7 is positioned at conical head 70 places, when button 11 is depressed, by power transmission shaft 9 latch 6 front ends are stretched in the locating hole 5, elasticity bayonet lock 10 is resisted against on the rear end face of conical head 70, realizes the location (seeing Fig. 2 state) of back cushion 4.When needing to adjust the use face of back cushion 4, button 11 is rotated to an angle, the recess 71 that makes conical head 70 is over against elasticity bayonet lock 10, at this moment, latch 6, power transmission shaft 9, button 11 are got back to original position under the power of the doing power of back-moving spring 8, latch 6 is withdrawn in the holder 7 (seeing Fig. 3 state), and back cushion 4 is promptly turning, button 11 low-angles rotations is depressed after adjusting again and get final product, operation is very easy.Certainly latch 6 also can adopt the control of screw knob control structure, as shown in Figure 5, be positioned at locating hole 5 places at vertical beam 3 internal thread sleeve pipe 12 is set, latch 6 is the screw rod of a band knob 13, when twisting knob 13, when making the front end of screw rod be positioned at locating hole 5, promptly realize the location, otherwise 4 of back cushions can rotate freely, and back cushion 4 is regulated.
