Abstract
The invention discloses a safety box provided with an automatic door bolt reset mechanism. The automatic door bolt reset mechanism comprises a brake, a reset spring, a first locating pin, a second locating pin and a torsion spring, and an arc positioning groove is provided with a first limiting position and a second limiting position. When the brake rotates around the fist locating pin under the action of the torsion spring and installation positions of the first limiting position and the second limiting position of the arc positioning groove are overlapped, the brake prevents a bolt head of the door bolt from stretching out, and a safety box door is located in an open state; when the brake rotates reversely around the fist locating pin under the action of the torsion spring and the second limiting position of the arc positioning groove and the installation position of the second locating pin are overlapped, and the brake is staggered from the stretching position of the bolt head of the door bolt, so that the bolt head of the door bolt stretches out completely under the elastic action of a compression spring, and the safety box door is located in a closed state. Therefore, the safety box can effectively prevent the condition that property damage is caused due to the fact that a handle is rotated when the door is forgotten to be closed.
Description
Technical field
The present invention relates to a kind of door bolt automatic reset mechanism, for promoting the door bolt of safe door to automatically reset, belong to safety cabinet production field.
Background technology
In prior art, conventional safe door does not generally configure door bolt automatic reset mechanism, therefore, when safe door is closed, needs swing handle, otherwise cabinet door can not be closed; And people are at closing time, often forget swing handle, thereby safe door are also in open mode, thereby very easily cause any property loss.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of safety cabinet with door bolt automatic reset mechanism is provided, can effectively avoid forgetting at closing time the property loss that swing handle causes, also can prevent that user is after opening the door simultaneously, due to external force or operate miss, under the state stretching out at door bolt, close the door, the situation that causes door bolt distortion, safe surface to destroy.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of safety cabinet with door bolt automatic reset mechanism, comprise doorframe, door bolt mechanism, this door bolt mechanism and door bolt are connected, door bolt automatic reset mechanism is installed between doorframe and door bolt mechanism, described door bolt automatic reset mechanism comprises brake and back-moving spring, and the two ends of described back-moving spring are interlockingly connected with door bolt and door bolt mechanism respectively; Brake passes through the first alignment pin, the second alignment pin location and installation on safe door door-plate, be fixed on safe door door-plate to the first described alignment pin, the second alignment pin longitudinal separation, described brake offers installation circular hole corresponding to the first alignment pin, and offer arc-shaped limit groove corresponding to the second alignment pin, the first alignment pin is through installing circular hole setting, and the second alignment pin is placed through arc-shaped limit groove; In the horizontal both ends of the surface of described brake, one of them end face and doorframe are adjacent, and other end is adjacent with the plunger outer rim of door bolt; The outer race of described the first alignment pin is connected to torque spring, the two ends of this torque spring respectively with brake on set two settle sites to be interlockingly connected; The torsion that described torque spring provides can impel brake to rotate around the first alignment pin, and its rotation amplitude is determined by arc-shaped limit groove; Described arc-shaped limit groove has the first extreme position, the second extreme position; Under the effect of brake at torque spring, around the first alignment pin rotation, while causing the first extreme position of arc-shaped limit groove to overlap with the second alignment pin installation site, brake blocks the plunger of door bolt and stretches out, and safe door is in opening; Under the effect of brake at torque spring, around the first alignment pin, counter-rotate, while causing the second extreme position of arc-shaped limit groove to overlap with the second alignment pin installation site, the stagger plunger extended position of door bolt of brake, the plunger of door bolt is stretched out completely under the elastic force effect of Compress Spring, and safe door is in automatic closed condition.
Described brake is a plate.
According to above technical scheme, with respect to prior art, the present invention has the following advantages:
The present invention can avoid forgetting at closing time the property loss that swing handle causes effectively, also can prevent that user is after opening the door simultaneously, due to external force or operate miss, under the state stretching out at door bolt, close the door, the situation that causes door bolt distortion, safe surface to destroy.

The specific embodiment
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation; Below with reference to accompanying drawing, explain technical scheme of the present invention.
The safety cabinet with door bolt automatic reset mechanism of the present invention, comprise cabinet, safe door, doorframe, door bolt mechanism, this door bolt mechanism and door bolt are connected, door bolt automatic reset mechanism is installed between doorframe and door bolt mechanism, described door bolt automatic reset mechanism comprises brake and back-moving spring, and the two ends of described back-moving spring are interlockingly connected with door bolt and door bolt mechanism respectively; Described brake is a plate, this plate passes through the first alignment pin, the second alignment pin location and installation on safe door door-plate, be fixed on safe door door-plate to the first described alignment pin, the second alignment pin longitudinal separation, described plate offers installation circular hole corresponding to the first alignment pin, and offer arc-shaped limit groove corresponding to the second alignment pin, the first alignment pin is through circular hole setting is installed, the second alignment pin is placed through arc-shaped limit groove, therefore, described plate can be around the first alignment pin rotation, and its rotation amplitude is determined by arc-shaped limit groove; In the horizontal both ends of the surface of described plate, one of them end face and doorframe are adjacent, and other end is adjacent with the plunger outer rim of door bolt; The outer race of described the first alignment pin is connected to torque spring, the two ends of this torque spring respectively with plate on set two settle sites to be interlockingly connected; The torsion that described torque spring provides can impel plate to rotate around the first alignment pin, and its rotation amplitude is determined by arc-shaped limit groove.
Operating principle of the present invention is as follows:
While opening the door, rotate counterclockwise handle, door bolt mechanism will drive door bolt motion, and back-moving spring is compressed.Torque spring resets, and brake, under torque spring effect, rotates around the first alignment pin, reaches the extreme position of arc-shaped limit groove, spacing by the second alignment pin.Now, door bolt is braked device and blocks, and safe door is in opening.
At closing time, only need touch door-plate, once brake contact with doorframe, under pressure, torque spring is compressed, drive brake to rotate backward around the first alignment pin, while reaching another extreme position of arc-shaped limit groove, spacing by the second alignment pin, whole door bolt is completely in pressure-less state, the spring automatic reset of compression, promotes door bolt and stretches out completely, and safe door is in automatic closed condition.
