Description

Technical Field

[0001] The present application relates to the technical field of fire doors, and in particular to a fireproof lock box. Background Art

[0002] Fire doors are an important part of fire protection equipment. Fire doors are normally open during normal monitoring and are held in place by the fire door electromagnetic door suction or positioned by the fire door electromagnetic releaser. When a fire occurs, the fire door will automatically close under the action of the door closer to prevent the spread of fire and smoke. Fireproof lock boxes are a special lock accessory that is mainly used to be installed on fireproof facilities such as fireproof doors and fireproof rolling shutter doors. Fireproof lock boxes have excellent fireproof performance and can effectively prevent the spread of fire and smoke when a fire occurs, ensuring the evacuation and safety of personnel.

[0003] In the patent document with the publication number CN209990428U, a fireproof rolling shutter door lock box is provided, comprising a box cover and a box body, the box cover comprises a panel and a folded edge surrounding the panel, the upper side plate and the lower side plate of the box body are provided with a folded plate folded toward one side of the folded edge, and a gap is provided between the folded plate, the folded edge and the panel. The box cover of the lock box is firmly connected to the lock box and the cost is low.

[0004] The above device is applied to fireproof rolling shutter doors, which requires the device to have a certain degree of heat resistance. The device is installed with electronic components inside, which are easily damaged after being heated. At the same time, solid materials conduct heat quickly. In the event of a fire, the metal material of the lock body that is in direct contact with the solid material may expand after being heated, thereby affecting the normal use of the lock. Utility Model Content

[0005] The present application proposes a fireproof lock box to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0007] A fireproof lock box comprises a shell mechanism, a front plate mechanism is installed in front of the shell mechanism, a driving mechanism is threadedly connected to the upper end of the front plate mechanism, the driving mechanism is rotatably connected to the shell mechanism, the driving mechanism passes through the front plate mechanism and the shell mechanism, a lock body mechanism is installed inside the shell mechanism, four guide mechanisms are arranged inside the shell mechanism and around the lock body mechanism, and the front end of the guide mechanism and the front end of the shell mechanism are located in the same vertical plane.

[0008] As a preferred embodiment, the shell mechanism includes a shell, and fixing plates are fixedly connected to the two side surfaces of the shell and the four corners of each side surface of the shell. The shell is hollow, and an operation port is opened on the front of the shell, and the front plate mechanism is slidably connected to the inside of the operation port.

[0009] By adopting the above technical solution, the shell mechanism is responsible for carrying the internal components and at the same time plays a role in protecting the internal components.

[0010] As a preferred embodiment, the driving mechanism includes a baffle plate, the front side of the baffle plate is elliptical, the back side of the upper end of the baffle plate is fixedly connected to a threaded rod, the end of the threaded rod away from the baffle plate is fixedly connected to a knob, and the front plate mechanism is threadedly connected to the side of the threaded rod.

[0011] By adopting the above technical solution and adjusting the driving mechanism, the state of the front plate mechanism can be adjusted.

[0012] As a preferred embodiment, the front plate mechanism includes a front baffle, a lock hole is opened in the middle of the front baffle, four through holes are opened on the front baffle, the guide mechanism is slidably connected inside the through holes, a threaded sleeve is fixedly connected to the back of the front baffle, the threaded rod is connected to the internal thread of the threaded sleeve, and the baffle covers the lock hole position.

[0013] By adopting the above technical solution and adjusting the state of the front plate mechanism, the effect of showing or hiding the lock body mechanism can be achieved.

[0014] As a preferred embodiment, the guide mechanism includes a fixed block, the fixed block is fixedly connected to a side of the housing away from the operation port, a guide rod is fixedly connected inside the fixed block, and the guide rod is slidably connected to the front baffle.

[0015] By adopting the above technical solution, the guide mechanism plays a role in limiting and guiding the front plate mechanism, thereby ensuring that the lock hole and the lock body mechanism are in height correspondence.

[0016] As a preferred embodiment, the lock body mechanism includes a lock body, which is fixedly connected to the inside of the shell away from the operating port. A lock head is installed in front of the lock body, and the lock head is located directly behind the lock hole. The size of the lock head is the same as the size of the lock hole.

[0017] By adopting the above technical solution, the lock body is installed on the side of the shell away from the fire-facing surface. Since there is no direct connection between the lock body and the fire-facing surface, the rate at which high temperature is transmitted to the inside of the lock body is reduced.

[0018] Beneficial effects of this application:

[0019] 1. This fireproof lock box is provided with a shell mechanism. When installing the shell mechanism, the operating port needs to be close to the fire-facing side. When the fire-facing side is on fire, the high temperature will first be transferred to the fireproof lock box along the solid medium, while the lock body mechanism and the fire-facing door panel are not in direct contact, thereby reducing the heat conduction efficiency. The front of the lock hole is covered with a baffle plate, which can be used to block the external airflow from contacting the lock head, thereby reducing the speed at which the lock head is deformed due to high temperature baking, and achieving a certain heat insulation effect;

[0020] 2. For this fireproof lock box, when unlocking is needed, the user only needs to rotate the baffle clockwise upwards. At this time, the rotation of the baffle drives the threaded rod to rotate, the threaded rod drives the threaded sleeve to move backward, and the threaded sleeve drives the front baffle to move backward, so that the lock head leaks out of the keyhole, and the unlocking operation can be achieved. After entering the other side of the door, the knob is rotated clockwise, and the knob drives the threaded rod to rotate, so that the state of the fireproof lock box is restored. The operation is simple. At the same time, a relatively stable protection space is set for the lock body inside the fireproof lock box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0027] Reference Figure 1-4A fireproof lock box includes a shell mechanism 1, a front plate mechanism 2 is installed in front of the shell mechanism 1, a driving mechanism 3 is threadedly connected to the upper end of the front plate mechanism 2, the driving mechanism 3 is rotatably connected to the shell mechanism 1, the driving mechanism 3 passes through the front plate mechanism 2 and the shell mechanism 1, a lock body mechanism 4 is installed inside the shell mechanism 1, four guide mechanisms 5 are arranged inside the shell mechanism 1 and around the lock body mechanism 4, and the front end of the guide mechanism 5 and the front end of the shell mechanism 1 are located in the same vertical plane.

[0028] Reference Figure 2 The housing mechanism 1 includes a housing 101, and fixing plates 102 are fixedly connected to the two sides of the housing 101 and the four corners of each side of the housing 101. The housing 101 is hollow, and an operation port 103 is provided in the front of the housing 101. The front plate mechanism 2 is slidably connected inside the operation port 103. When installing the housing mechanism 1 on the door panel, it is necessary to place the side of the operation port 103 of the housing mechanism 1 close to the fire-facing surface of the door panel, and fix the fixing plate 102 by bolts, so that the housing 101 is installed on the door panel, and the installation of the housing mechanism 1 is completed.

[0029] Reference Figure 4 The driving mechanism 3 includes a baffle plate 301, the front of the baffle plate 301 is oval, the back of the upper end of the baffle plate 301 is fixedly connected to a threaded rod 302, the end of the threaded rod 302 away from the baffle plate 301 is fixedly connected to a knob 303, and the front plate mechanism 2 is threadedly connected to the side of the threaded rod 302. The baffle plate 301 is rotated clockwise, and the baffle plate 301 drives the threaded rod 302 to rotate, so that the threaded rod 302 drives the front plate mechanism 2 to move backward. When the staff enters the other side of the door panel, the knob 303 can be rotated clockwise to drive the front plate mechanism 2 to move forward, and the baffle plate 301 rotates back to its original position, thereby realizing the adjustment of the driving mechanism 3 and the front plate mechanism 2.

[0030] Reference Figure 4 The front plate mechanism 2 includes a front baffle plate 201, which is slidably connected to the inside of the operation port 103. A lock hole 204 is provided in the middle of the front baffle plate 201. Four through holes 202 are provided on the front baffle plate 201. A guide mechanism 5 is slidably connected to the inside of the through hole 202. A threaded sleeve 203 is fixedly connected to the back of the front baffle plate 201. The threaded rod 302 is threadedly connected to the inner thread of the threaded sleeve 203. The baffle plate 301 covers the position of the lock hole 204. When the driving mechanism 3 drives the threaded sleeve 203 to move, the guide mechanism 5 penetrates the through hole 202, so that the threaded sleeve 203 drives the front baffle plate 201 to move along the guide mechanism 5, thereby making the lock body mechanism 4 appear from the lock hole 204. At this time, if the driving mechanism 3 is rotated in the reverse direction, the lock hole 204 will be away from the lock body mechanism 4, and the lock hole 204 will be blocked by the front baffle plate 201. That is, by adjusting the state of the front plate mechanism 2, the effect of showing or hiding the lock body mechanism 4 is achieved.

[0031] Reference Figure 4 The guide mechanism 5 includes a fixed block 501, which is fixedly connected to the side of the housing 101 away from the operation port 103. A guide rod 502 is fixedly connected to the fixed block 501, and the guide rod 502 is slidably connected to the front baffle 201. There are four guide mechanisms 5 in total, and the four guide mechanisms 5 correspond to the positions of the four through-holes 202 respectively, and the guide rod 502 is slidably connected to the through-holes 202 corresponding to the positions. When the front baffle 201 moves forward and backward, the through-hole 202 on the front baffle 201 slides along the guide rod 502, and the guide rod 502 plays a role in limiting and guiding the front plate mechanism 2, thereby ensuring that the lock hole 204 corresponds to the lock body mechanism 4 in height.

[0032] Reference Figure 4 The lock body mechanism 4 includes a lock body 401, which is fixedly connected to the side of the housing 101 away from the operation port 103. A lock head 402 is installed in front of the lock body 401. The lock head 402 is located directly behind the lock hole 204, and the size of the lock head 402 is the same as that of the lock hole 204. The lock body 401 is installed on the side of the housing 101 away from the operation port 103, and the side of the door panel close to the operation port 103 is the fire-facing surface. Since there is no direct solid connection component between the lock body 401 and the fire-facing surface, the rate of high temperature transmission to the inside of the lock body 401 is reduced. The baffle 301 can be used to prevent the external airflow from contacting the lock head 402, thereby reducing the speed of deformation of the lock head 402 due to high temperature baking, thereby achieving a temperature insulation effect.

[0033] Working principle: When installing the shell mechanism 1 on the door panel, please note that the operating port 103 of the shell mechanism 1 needs to be close to the fire-facing surface of the door panel, and the fixing plate 102 is fixed by bolts, so that the shell 101 is installed on the door panel, and the installation of the shell mechanism 1 is completed. Turn the baffle plate 301 clockwise, and the baffle plate 301 drives the threaded rod 302 to rotate, so that the threaded rod 302 drives the front panel mechanism 2 to move backward. When the staff enters the other side of the door panel, the knob 303 can be rotated clockwise to drive the front panel mechanism 2 to move forward, and the baffle plate 301 rotates back to its original position, thereby adjusting the state of the driving mechanism 3 and the front panel mechanism 2.

[0034] When the driving mechanism 3 drives the threaded sleeve 203 to move, the guide mechanism 5 penetrates the through hole 202, so that the threaded sleeve 203 drives the front baffle 201 to move along the guide mechanism 5, and then the lock body mechanism 4 is exposed from the lock hole 204. At this time, if the driving mechanism 3 is rotated in the opposite direction, the lock hole 204 will be away from the lock body mechanism 4, and the lock hole 204 will be blocked by the front baffle 201, that is, by adjusting the state of the front plate mechanism 2, the effect of showing or hiding the lock body mechanism 4 is achieved. The lock body 401 is installed on the side of the housing 101 away from the operating port 103, and the side of the door panel close to the operating port 103 is the fire-facing surface. Since there is no direct solid connection component between the lock body 401 and the fire-facing surface, the rate of high temperature transmission to the inside of the lock body 401 is reduced. The baffle 301 can be used to block the external airflow from contacting the lock head 402, thereby reducing the speed of deformation of the lock head 402 due to high temperature baking, thereby achieving the effect of heat insulation.

Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
