Description

The safety device of door

Technical field

The utility model relates to a kind of door, relates in particular to a kind ofly to be used for preventing pointing or safety device that other body part is crushed by door and doorframe.

Background technology

Because one side that door engages with doorframe, when door opening state, can produce dangerous slit and angle, because the effect of moment, the strength that crushes of this dangerous slit and angle is greater than close the door 1,100 times of limit strength of handle, and this angle trap is easy to damage under the situation of no early warning, especially child; Yet up to the present, but do not see effective solution always; Moreover when crushing incident, regular meeting causes the irreparable harm consequence, the lighter's fracture, weight person maimed person.

The utility model content

Technical problem underlying to be solved in the utility model is, overcome the defective that the slit and the angle of present door and doorframe jointing edge crush human body easily, and provide a kind of safety device, it can avoid finger or other position of health to put in this angle and the slit and crushed, and is easy to use and durable.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of safety device is characterized in that, the plate body for employing has enough rigidity and one-body molded extension one length of flexible material comprises: a central part; One fixed part is connected in a side of this central part, and it is used for fixing at a doorframe; One movable part is connected in the opposite side of this central part, and it is used to cover slit and angle between a doorframe and the door.

The safety device of aforesaid door, wherein the free end of movable part is formed with a cylinder.

The safety device of aforesaid door, wherein movable part forms bending near its free-ended position.

The safety device of aforesaid door, wherein the width of movable part is greater than the width of this fixed part.

The utility model solves its technical problem also can adopt following technical scheme:

A kind of safety device is characterized in that, the plate body for employing has enough rigidity and flexible material formation extension one length comprises: a torque spring; One fixed part is connected in a side of this torque spring, and it is used for fixing at a doorframe; One movable part is connected in the opposite side of this torque spring, and it is used to cover slit and angle between a doorframe and the door.

The safety device of aforesaid door, for the free end that makes movable part can be resisted against door glidingly, cause obstruction with the switch smoothness of avoiding opposite house, described movable part forms bending near free-ended position, and can form a cylinder at free end, allow form line between the surface of cylinder and door and contact.

Wherein movable part forms bending near its free-ended position.

The safety device of aforesaid door, wherein the width of movable part is greater than the width of described fixed part.

Cooperate the elasticity of movable part itself to make the free end of movable part be resisted against door by this torque spring, allow slit and angle between doorframe and the door be subjected to movable part and cover, crushed to avoid finger or other position of health to stretch into this slit and angle, and had easy to use and durable advantage.

Safety device of the present utility model can also be resisted against a damping that is produced by movable part except having the function in slit of covering between doorframe and the door, avoid high wind or other external force moment to promote door and shut.

The specific embodiment

Fig. 1 is first preferred embodiment of the safety device 1 of the utility model door, it is can adopt such as steel plate, plastic cement, plastic-steel etc. to have enough rigidity and flexible material, plate body with one-body molded mode elongation moulding one length, make it have a columned central part 11, side at this central part 11 connects a tabular fixed part 12, and the opposite side of central part 11 then connects a tabular movable part 13; On the described fixed part 12 several holes 121 can be set, fixed part 12 be fixed in doorframe 2 (as shown in Figures 3 and 4) to utilize screw to pass this hole 121; In addition, this movable part 13 is formed with a bend 132 near free-ended appropriate location, and free end then is provided with the cylinder 131 of a diameter greater than these movable part 13 thickness.Fig. 3 and Fig. 4 show that simultaneously working as fixed part 12 is fixed in the doorframe 2 that is located at wall 4 limits, and door is when opening, can make its free-ended cylinder 131 be resisted against the end limit of door by movable part 13 elasticity own, in this state, movable part 13 can cover slit and the angle between doorframe 2 and the door 3.

Fig. 5 and Fig. 6 show when door 3 with respect to doorframe 2 rotations, 90 degree and desire at closing time, jointing edge at doorframe 2 and door 3 can produce a slit A and an angle, at this moment, the cylinder 131 of movable part 13 will be displaced to the side surface of door from the side of door 3, can keep covering this slit A equally, when door 3 is closed fully (as Fig. 7 and shown in Figure 8), 3 pairs of movable parts 13 of door are bestowed maximum force and are out of shape; When treating that open the door next time, movable part 13 can allow movable part 13 in the process of homing because of being out of shape stored elastic force, can cover slit A constantly, avoids finger or other position of health to stretch into this slit and crushed.

Fig. 2 shows second kind of embodiment of the utility model safety device 1, can adopt compound mode group structure, it can replace aforesaid central part 11 by a torque spring 11A, and connect a fixed part 12 and a movable part 13 respectively in the both sides of this torque spring 11A, with Specifications's, this fixed part 12 can be fixed in doorframe 2, elasticity by this torque spring 11A, the elasticity that cooperates movable part 13 itself again, can make the free-ended cylinder 131 of movable part 12 more stably be resisted against door 3, make doorframe 2 and the slit A of door between 3 be subjected to movable part and cover, avoid pointing or other position of health is stretched into this slit and crushed with angle.

Safety device 1 of the present utility model can also be resisted against door 3 dampings that produced by movable part 13 except having the function of covering doorframe 2 and the slit of door between 3, avoid high wind or other external force moment to promote door and shut.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
