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, the door bolt for promoting safe door automatically resets, and belongs to guarantor
Dangerous cabinet production field.
Background technology
In prior art, conventional safe door does not typically configure door bolt automatic reset mechanism, and therefore, safe door is closed
When, need swing handle, otherwise cabinet door can not close；And people are at closing time, often forgetting swing handle, thus safe door
Also in open mode, thus easily causing any property loss.
Content of the invention
The present invention is directed to the deficiencies in the prior art, provides a kind of safety cabinet with door bolt automatic reset mechanism, Ke Yiyou
Avoid, in the property loss forgetting that swing handle causes at closing time, being also possible to prevent user after enabling, due to outer to effect simultaneously
Power or operational error, close the door in the state of door bolt stretches out, and cause the situation that door bolt deformation, safety cabinet tank surface 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, including doorframe, door bolt mechanism, this door bolt mechanism is joined with door bolt
It is dynamically connected, door bolt automatic reset mechanism is installed between doorframe and door bolt mechanism, described door bolt automatic reset mechanism includes making
Dynamic device and back-moving spring, the two ends of described back-moving spring are interlockingly connected with door bolt and door bolt mechanism respectively；Brake passes through first
, on safe door door-plate, the first described alignment pin, the second alignment pin are longitudinally spaced for alignment pin, the second alignment pin location and installation
Be fixed on safe door door-plate, described brake offers installation circular hole corresponding to the first alignment pin, and corresponds to second
Alignment pin opens up arc-shaped limit groove, and the first alignment pin passes through installs circular hole setting, and the second alignment pin is then put through arc-shaped limit groove
Put；In the horizontal both ends of the surface of described brake, one of end face is adjacent with doorframe, other end then with the plunger of door bolt outside
Edge is adjacent；The periphery of described first alignment pin is socketed with torque spring, and the two ends of this torque spring are set with brake respectively
The two arrangement sites put are interlockingly connected；The torsion that described torque spring provides can promote brake to rotate around the first alignment pin,
Its rotational steps is determined by arc-shaped limit groove；Described arc-shaped limit groove has the first extreme position, the second extreme position；Work as system
Dynamic device rotates around the first alignment pin in the presence of torque spring, causes the first extreme position and second positioning of arc-shaped limit groove
When pin installation site overlaps, the plunger that door bolt is blocked in brake is stretched out, and safe door is in opening；When brake is in torsion
Reversely rotate around the first alignment pin in the presence of spring, cause the second extreme position and the second alignment pin peace of arc-shaped limit groove
When holding position overlaps, brake is staggered the plunger extended position of door bolt, and the plunger of door bolt is complete under the elastic force effect of compression spring
Entirely stretch out, safe door is in the state of being automatically switched off.
Described brake is a plate.
According to above technical scheme, with respect to prior art, the invention has the advantages that
The present invention can be effectively prevented from, in the property loss forgetting that swing handle causes at closing time, being also possible to prevent simultaneously
User, after enabling, due to external force or operational error, closes the door in the state of door bolt stretches out, and causes door bolt deformation, safety cabinet
The situation that tank surface is destroyed.

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.
The safety cabinet with door bolt automatic reset mechanism of the present invention, including cabinet, safe door, doorframe, bolt
Mechanism, this door bolt mechanism and door bolt are connected, and install door bolt automatic reset mechanism between doorframe and door bolt mechanism, described
Door bolt automatic reset mechanism includes brake and back-moving spring, the two ends of described back-moving spring respectively with door bolt and door bolt mechanism
It is interlockingly connected；Described brake is a plate, and this plate passes through the first alignment pin, the second alignment pin location and installation in safe door door
On plate, the first described alignment pin, the second alignment pin are fixed on safe door door-plate longitudinally spacedly, and described plate corresponds to
First alignment pin offers installation circular hole, and corresponds to the second alignment pin and open up arc-shaped limit groove, and the first alignment pin passes through to be installed
Circular hole is arranged, and the second alignment pin then passes through arc-shaped limit groove to place, and therefore, described plate can rotate around the first alignment pin, its
Rotational steps are determined by arc-shaped limit groove；In the horizontal both ends of the surface of described plate, one of end face is adjacent with doorframe, separately
End face is then adjacent with the plunger outer rim of door bolt；The periphery of described first alignment pin is socketed with torque spring, this torque spring
Two ends are interlockingly connected with set two arrangement sites on plate respectively；The torsion that described torque spring provides can promote plate
Rotate around the first alignment pin, its rotational steps is determined by arc-shaped limit groove.
The operation principle of the present invention is as follows:
During enabling, rotate counterclockwise handle, door bolt mechanism will drive door bolt to move, and back-moving spring is compressed.Torque spring
Reset, brake, under torque spring effect, rotates around the first alignment pin, reaches the extreme position of arc-shaped limit groove, that is, by the
Two alignment pins are spacing.Now, door bolt is blocked by brake, and safe door is in opening.
At closing time, only door-plate need to be touched, once brake and door frame contact, under pressure, torque spring is compressed,
Drive brake to rotate backward around the first alignment pin, reach arc-shaped limit groove another extreme position when, that is, fixed by second
Position pin is spacing, and whole door bolt is completely in pressure-less state, the spring automatic reset of compression, promotes door bolt fully extended, insurance
Cabinet door is in the state of being automatically switched off.
