Abstract

The utility model relates to a bed for preventing injure from earthquake, which is composed of a bed frame, bed plates and a bed head. The utility model is characterized in that the bed plates are composed of two blocks or three blocks, the bed plate which is close to the bed head is combined with the bed head into a whole and connected with the bed frame with a rotation shaft, the bed plate which is close to a bed tail is connected with the bed frame by hinges, and the other ends of the bed plates are connected together and supported by clamping pins. When earthquake happens, a vertical hammer is tilted, the clamping pins are evacuated, two blocks of bed plates turn downwards, the people who lie on the bed are lowered to the bed bottom, and then the bed head covers the whole bed frame and shelters the human bodies from harm.

Description

Bed for preventing injure from earthquake

The utility model can make human body be enclosed in the body and the anti-earthquake bed that preserves from when relating to a kind of earthquake.

(name is called " anti-earthquake bed " to the utility application of having announced, notification number 2089742U, application number 91209372.2) provides a kind of anti-earthquake bed, the people who lies on a bed when earthquake falls, the stop clutch makes a side plate remove stop, be turned to horizontal level by vertical position and form case lid under the effect of turnover spring, human body is in the casing of a sealing.This application shortcoming is: be difficult to upset by spring force when side plate is heavier, and side plate can not satisfy enough solid requirement again when light.

The utility model and above-mentioned utility application belong to same goal of the invention, and promptly this has the function of automatically human body being sheltered when earthquake, guarantee personal safety.

The utility model is different with aforementioned utility application structure, and its action is sensitive more reliable when earthquake.

The utility model is made up of bedstead, bed board and the head of a bed, and its bed board is formed by two or three, combine by the head of a bed bed board and the head of a bed (1), and rotates (2) around the shaft.Be connected with hinge with the bedstead afterbody by tailstock bed board one end, the other end rides on the plate tongue (6) by head of a bed bed board.By both sides, plate tongue below head of a bed bed board, there is bayonet lock (5) to support whole bed board middle part.Bayonet lock during earthquake (5) break away to support and to make two bed boards overturn downwards, and at the bottom of the people who lies on a bed fell bed, the head of a bed rotated and covers the whole bed frame human body is sheltered simultaneously.

When bed board is formed by three, bed board (26) in the middle of increasing by in the middle of two bed boards, it rides on the bayonet lock (5), and its balance is controlled by rope (23), and all there is the plate tongue at middle bed board two ends, are supported the bed board on both sides by the plate tongue.Bayonet lock during earthquake (5) breaks away from support, and middle bed board falls, and realizes that by head of a bed bed board with by the tailstock bed board downward upset makes the head of a bed (1) cover whole bedstead simultaneously.The whereabouts of middle bed board has the lead (24) that is fixed on the bedstead side to lead, simultaneously because the upset of the head of a bed (1) pulling rope (23) makes middle bed board balance fall.

The disengaging of bayonet lock (5) is supported owing to earthquake causes upright hammer (9) to topple over pulling rope (15) and is realized.

Being active in one's movements that the utility model is sheltered human body when earthquake automatically reliably is clearly, guaranteed human body safety.

Further specify the utility model embodiment below in conjunction with accompanying drawing.

Fig. 1 is the side-looking structure diagram of bed board by two anti-earthquake beds of forming.

Fig. 2 is the bayonet lock schematic diagram of movements.

Fig. 3 is bedstead afterbody and reflection " V " template and the horizontal relative position sketch of upright hammer.

Fig. 4 is when setting up safety pin, the safety pin schematic diagram of movements.

Fig. 5 is that bed board is by three anti-earthquake bed side-looking structure diagrams of forming.

Figure number in the accompanying drawing is represented respectively: (1)-head of a bed, and (2)-rotating shaft, (3)-by head of a bed bed board, (4)-and safety pin, (5)-bayonet lock, (6)-headpiece plate tongue, (7)-and by the tailstock plate, (8)-hinge, (9)-Li hammer, (10)-and bedstead, (11)-" V " template, (12)-pulley, (13)-Li hammers support into shape, (14)-and thin wall circular, (15)-bayonet lock control rope, (16)-shift fork, (17)-spring leaf, (18)-and lever catch, (19)-safety pin pulley, (20)-safety pin control rope, (21)-safety pin, (22)-and the safety pin shell fragment, (23)-intermediate plate control rope, (24)-intermediate plate lead, (25)-intermediate plate rope control pulley, (26)-and middle bed board, (27)-head of a bed pulley, (28)-lever.

As shown in Figure 1, bed board is formed by two.Head of a bed bed board (3) is combined with iron plate with the head of a bed (1), can be with rotating shaft (2) upset downwards, and rotating shaft (2) is contained on the bedstead of head of a bed part.Tailstock bed board (7) is connected with the afterbody of bedstead with hinge (8), and the other end rides on the headpiece tongue (6), and this plate tongue is connected with head of a bed bed board with screw, and screw sinks in the bed board.The two sides of bed board respectively have a bayonet lock (5) to support head of a bed bed board.As Fig. 1 and Fig. 2; Bayonet lock (5) can be the central shaft rotation with little axle, and little axle is installed on the middle leg of a side.Eave tile by shift fork (16) partly blocks bayonet lock (5), and this declutch shift shaft also is installed on the middle leg of a side.Be provided with upright hammer (9) in the tailstock bedstead, upright hammer (9) stands up on upright hammer support (13).Upright hammer support (13) is installed on the tailstock bottom plate (10).Be welded with thin wall circular (14) on the upright hammer support.There is centre bore upright hammer lower end, with screw rope (15) is fixed in this hole.The upright hammer of general small earthquake is difficult for toppling over, and upright hammer must be toppled over when violent earthquake.The annulus that its underpart fell in when upright hammer was toppled over partly is stuck on the thin wall circular (14), and upright hammer makes the support of bayonet lock (5) disengaging to bed board just as a lever effectively spurs rope (15), and at this moment bed board stirs downwards, and the head of a bed covers on bedstead.

As shown in figures 1 and 3, upright hammer no matter toward which side to toppling over because the effect of " V " template (11), upright hammer can only be poured in the bedstead afterbody neutral gear.

By shown in Figure 5, bed board is formed by three.Middle bed board rides on the bayonet lock (5).With bayonet lock (5) is support, controls its balance by rope (23).Middle bed board two ends have the plate tongue to support head of a bed bed board and tailstock bed board.The plate tongue at two ends is slightly different; Plate tongue by the head of a bed one end all blocks head of a bed bed board up and down.Middle bed board falls to having lead (24) to be guiding, and lead is contained on the bedstead both sides.Because the other end of rope (23) is fixed on the head of a bed (1), pulley (27) is fixed on the bedstead, and the upset of the head of a bed has pulling function by rope (23) to middle bed board.The distance of the high more this pulling in position of pulley (27) is big more.

As shown in Figure 4, the utility model can increase safety pin, and its position is lower than bayonet lock slightly on the bayonet lock next door.As Fig. 4, safety pin (21) is on the operating position.It is to prevent that misoperation from topple over upright hammer, thereby bed board stirs setly, and at this moment bayonet lock (5) breaks away from and supports, and safety pin is born support.Pull lever (28) and make it to be stuck in and promptly pull out safety pin on the lever catch, this is in running order.

Whole bedstead can be done enough solidly, and it can be made with timber, also can be with hophornbeam in conjunction with making, and for the purpose of sketch was clear, not shown bedstead had how many bar supports of how many bar legs.

Head of a bed back is welded with several steel pipes or channel-section steel with enough firm solid degree of being.Because of there is no architectural feature, so this part is not shown specifically in the drawings yet.
