Abstract

The utility model discloses a foldable and deformable stretcher, which comprises foldable support rods on both sides, two-way ratchet pawls are installed on the folding points of the support rods, and a three-section inner frame is fixed between the support rods on both sides. The joints between the two frames are hinged, and the two sides of the end of the first frame are respectively hinged with the adjacent support rods; the corresponding ends of the second and third frames are rigidly connected to an incomplete gear, and the two gears are meshed. The gear shaft is fixed on the supporting rod corresponding to its position; the longitudinal rod of the first frame is a sleeve structure, and the longitudinal rod of the third frame is sleeved with the rear supporting rod. When the stretcher is deformed, the inner frame can be deformed into a chair shape by adjusting the positioning direction of the two-way ratchet pawl and lifting the rear end of the stretcher to the required angle. The utility model has the advantages of simple structure, flexible and convenient operation, and the folding angle of the stretcher can be adjusted at will.

Description

Can sell off the shape stretcher

Technical field

This utility model relates to a kind of stretcher, particularly a kind of sold off shape stretcher that is fit to by narrow stair.

Background technology

Stretcher is a kind of wounded of transporting, patient's a common tool.Existing common stretcher all is non deformable, and its length is generally 180cm.When transporting the wounded or patient by narrow stair, because the radius of turn of stair is little, this stretcher can't be flatted turn, and the bigger angle that must tilt can be passed through, and in passing through the whole process of stair, the wounded or patient get repeatedly passive change position.Like this, the people who not only carries a stretcher is very tired, and the wounded or patient also are difficult to be subjected to, and particularly when the rescue severe wounded or severe case, can not excessively be jolted often by the person of lifting.Therefore, common stretcher is very inapplicable.At present existing multiple folding stretcher appears on the market, and its structure all is a four-bar mechanism, and stretcher can be folded into the seat form.Yet these stretcher structure complexity during distortion, get location, many places, fixing, and process is very loaded down with trivial details, needs two people's compounding practices just can finish usually.

Summary of the invention

The purpose of this utility model is to overcome that common stretcher can not be out of shape and existing four-bar mechanism stretcher structure complexity, on-deformable defective, provides a kind of simple in structure, flexible operation, sold off shape stretcher easy to use.

The technical scheme that realizes above-mentioned purpose is: a kind of shape stretcher of selling off, comprise that both sides can roll over support bar, and it is characterized in that two-way click is installed on the break of described support bar, and the two sections support bars in the front and back on each limit are hinged by described click; Be fixed with three sections folding inner frames between the support bar of both sides, first and second segment frames is corresponding with the leading portion post position, and the 3rd segment frames is corresponding with the back segment post position; Joint between first and second segment frames is hinged, and both sides, the first segment frames termination are hinged with contiguous support bar respectively; The partial gear that respectively has been rigidly connected on the corresponding termination of second section and the 3rd segment frames, two gears engaged, gear shaft is fixed on the support bar of its position correspondence; The longitudinal rod of first segment frames is a sleeve structure, and the longitudinal rod of the 3rd segment frames interlocks parts by one and the back segment support bar interlocks.

In use, if need the stretcher distortion, regulate the orientation of two-way click earlier, the rear end of support bar can upwards be lifted, hand steered then stretcher follower head upwards is raised to required angle, can make inner frame be deformed into an arm-chair shape.In this process, along with lifting of support bar rear end, the rear end that inner frame is the 3rd section is also lifted synchronously, support bar rotates on the jointed shaft of break, and the 3rd section partial gear of inner frame also rotates, and the partial gear on second segment frames of drive simultaneously and its engagement rotates, the hinged place that the rotation of driven gear must drive first and second segment frames is upturned, at this moment, first segment frames not only rotates along its jointed shaft, and inner sleeve wherein can be drawn out certain-length naturally.So just formed the arm-chair form of three sections setback shapes.When stretcher restores, oppositely regulate the detent mechanism of click, the application of force flattens support bar and gets final product.

The further improvement project of above-mentioned technology is: at the front end of described both sides support bar a planetary gear is installed respectively, can be realized the single patient of the transporting walking of going downstairs pacifically.

This utility model is simple in structure, flexible operation, convenient, the turning up angle and can arbitrarily adjust of stretcher, stretcher after the distortion is easy to by narrow stair, and the people who carries a stretcher is not painstaking, patient can seat on stretcher, do not feel bad, more can not jolted and turn from side to side, the people who is fit to the various patient's condition uses.

Among the figure: 1. leading portion support bar, 2. back segment support bar, 3. click 4. interlocks parts, 5. the 3rd section side jamb rod of inner frame, 6. second section side jamb rod of inner frame, 7. inner frame first section side jamb rod, 8. expansion link, 9,10. partial gear, 11. axostylus axostyles, 12. support rails, 13. planetary gears.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

As Figure 1-3, this utility model can be sold off the shape stretcher, main body can be rolled over stretch tight on support bar, three sections folding inner frames that are connected with the both sides support bar and the inner frame shield of dress and the connector on each break by both sides and be formed, on the leading portion support bar 1 of both sides support bar and the junction point of back segment support bar 2 two-way click 3 is installed, the two sections support bars in front and back are hinged by this click; First and second segment frames of syllogic inner frame is corresponding with leading portion support bar 1 position, and the 3rd segment frames is corresponding with back segment support bar 2 positions; Joint between first and second segment frames is hinged by axostylus axostyle 11, and both sides, the first segment frames termination are hinged with contiguous support bar respectively, and promptly the side jamb rod 7 of first section inner frame is hinged with contiguous support bar 1; Respectively be rigidly connected on frame bar 5 both corresponding terminations of the side jamb rod 6 of second section inner frame and the 3rd section inner frame a partial gear 9 and 10, two gears engaged, gear shaft is fixed on the support bar 1 of its position correspondence; Be socketed with expansion link 8 in the side jamb rod 7 of first segment frames, promptly form the longitudinal rod sleeve structure of first segment frames, the side jamb rod 5 of the 3rd segment frames interlocks parts 4 by one on the back segment support bar 2 and interlocks with back segment support bar 2.

In the present embodiment, both sides support bar 1 and 2 front end are respectively installed a planetary gear 13.
