Description

A laboratory access control device Technical Field

[0001] This utility model relates to the field of equipment for managing laboratory personnel, and in particular to a laboratory access control device. Background Technology

[0002] A laboratory is a place for conducting experiments. It is the cradle of science, the base of scientific research, and the source of technological development, playing a vital role in technological advancement. Access control devices are used to open or close passageways in laboratories. When the passageway is open, personnel can freely enter and exit the laboratory; when the passageway is closed, personnel cannot enter or exit. Therefore, laboratory access control devices can effectively prevent unauthorized personnel from entering the laboratory.

[0003] Existing laboratory access control equipment typically incorporates biometric technology to identify relevant personnel. The control equipment then controls the opening or closing of the door. Usually, the door opens or closes automatically after the relevant personnel's identity is identified.

[0004] However, existing access control devices for laboratories are inconvenient to open in the event of a power outage, especially in emergency situations where the door should be opened promptly to allow personnel inside the laboratory to handle any unforeseen circumstances.

[0005] Therefore, existing laboratory access control devices have the technical problem of being inconvenient to open when the power is off. Summary of the Invention

[0006] This utility model provides a laboratory access control device that solves the technical problem that existing laboratory access control devices are inconvenient to open when the power is off.

[0007] Some implementation schemes for solving the above-mentioned technical problems include:

[0008] A laboratory access control device includes a door installed in a wall, the door opening or closing a passageway in the wall;

[0009] A drive assembly, which is mounted on the wall and drives the door to open or close the passage of the wall;

[0010] The access control component includes a wall-mounted reader and a controller communicating with the reader, the controller controlling the drive component;

[0011] The drive assembly includes a rotating shaft rotatably connected to the wall, a sleeve being fitted over the rotating shaft, the door being mounted on the sleeve, and the rotating shaft driving the door through the sleeve.

[0013] The rotating shaft is slidably connected to the sleeve, and an elastic element is provided between the rotating shaft and the sleeve to push the rotating shaft so that the driving hole engages with the driving column.

[0014] Preferably, the rotating shaft is further provided with a handle for operating the rotating shaft to disengage the driving hole from the driving column, and the sleeve is provided with a strip-shaped hole that cooperates with the handle, the strip-shaped hole penetrating the side wall of the sleeve.

[0015] Preferably, the handle is fixed to the rotating shaft by threads, the rotating shaft is provided with a threaded hole, the handle is provided with a screw that mates with the threaded hole, and the handle and the screw are an integral structure.

[0016] Preferably, the drive mechanism further includes a worm gear disposed on the output shaft, and the drive mechanism further includes a worm cooperating with the worm gear, the worm being driven by a motor, and the motor being controlled by the controller.

[0017] Preferably, the drive mechanism further includes a mounting bracket, which is mounted on a wall, the output shaft is rotatably connected to the mounting bracket, and the worm gear is fixed to the mounting bracket by a bracket.

[0018] Preferably, the worm gear includes a mating part that mates with the bracket, the bracket is provided with a mating hole that mates with the mating part, and the motor is fixed to the bracket.

[0019] Preferably, a rolling bearing is provided between the mating part and the mating hole, and the bracket is fixed to the mounting bracket by screws.

[0022] Preferably, the elastic element is a spring, with one end of the elastic element contacting the lower plate and the other end of the elastic element contacting the sleeve.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] A coupling is used, comprising an upper plate and a lower plate. The upper plate has a drive column, and the lower plate has a drive hole. The coupling also includes a flexible element. Under normal operating conditions, the flexible element pushes the lower plate to engage the drive hole with the drive column, allowing the output shaft to drive the rotating shaft. In the event of a power outage, the lower plate can be easily operated to overcome the force of the flexible element, disengaging the drive column from the drive hole, thus opening the door. The operation is very convenient.

Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Referring to Figures 1 to 6, a laboratory access control device includes a door 2 installed on a wall 1, the door 2 opening or closing a passage in the wall 1;

[0041] A drive assembly 3 is installed on the wall 1, and the drive assembly 3 drives the door 2 to open or close the passage of the wall 1;

[0042] The access control component includes a reader 31 installed on the wall 1 and a controller communicating with the reader 31, the controller controlling the drive component 3;

[0043] The drive assembly 3 includes a rotating shaft 32 rotatably connected to the wall 1, a sleeve 33 is provided on the rotating shaft 32, the door 2 is installed on the sleeve 33, and the rotating shaft 32 drives the door 2 through the sleeve 33.

[0044] The drive assembly 3 further includes a drive mechanism installed on the wall 1. The drive mechanism includes an output shaft 34. A coupling 35 is provided between the output shaft 34 and the rotating shaft 32. The coupling 35 includes an upper plate 351 installed on the output shaft 34 and a lower plate 352 installed on the rotating shaft 32. The upper plate 351 is provided with a drive column 353 for transmitting power, and the lower plate 352 is provided with a drive hole 354 that cooperates with the drive column 353.

[0045] The rotating shaft 32 is slidably connected to the sleeve 33, and an elastic element 355 is provided between the rotating shaft 32 and the sleeve 33 to push the rotating shaft 32 so that the driving hole 354 engages with the driving column 353.

[0046] Referring to Figures 1 to 6, in some embodiments, both the controller and the identifier 31 are common electronic components in the prior art.

[0047] In some embodiments, the recognizer 31 may be a biometric recognizer 31, such as a face recognizer 31, a voice recognizer 31, an iris recognizer 31, etc.

[0048] In some embodiments, the rotating shaft 32 is further provided with a handle 321 for operating the rotating shaft 32 to disengage the drive hole 354 from the drive column 353, and the sleeve 33 is provided with a strip hole 331 that cooperates with the handle 321, the strip hole 331 penetrating the side wall of the sleeve 33.

[0049] Understandably, since the rotating shaft 32 is sleeved inside the sleeve 33, it is usually inconvenient to operate the lower plate 352 by rotating the shaft 32 to move it. However, by setting the handle 321, the handle 321 can be operated conveniently, so that the handle 321 drives the rotating shaft 32 and the lower plate 352 to move, thereby causing the drive column 353 to disengage from the drive hole 354.

[0050] In some embodiments, the handle 321 is fixed to the rotating shaft 32 by threads, the rotating shaft 32 is provided with a threaded hole, the handle 321 is provided with a screw that mates with the threaded hole, and the handle 321 and the screw are an integral structure.

[0051] Referring to Figures 1 to 6, it can be understood that a screw hole is provided on the rotating shaft 32, and there is no protruding part on the rotating shaft 32, so that the rotating shaft 32 and the sleeve 33 are easy to assemble.

[0052] In some embodiments, when the lower end of the rotating shaft 32 extends beyond the lower end of the sleeve 33, the handle 321 can be directly set at the lower end of the rotating shaft 32, and the setting of the strip groove can be omitted.

[0053] In some embodiments, the drive mechanism further includes a worm gear 341 disposed on the output shaft 34, and the drive mechanism further includes a worm 342 cooperating with the worm gear 341, the worm 342 being driven by a motor 343 being controlled by the controller.

[0054] Specifically, since the worm 342 and worm wheel 341 have a self-locking characteristic, there is no need to set up a separate locking mechanism to lock the output shaft 34 or the rotating shaft 32, which simplifies the structure of the drive assembly 3.

[0055] Especially in the event of a power outage, the worm gear 342 and worm wheel 341 have self-locking characteristics, so the door 2 can remain closed even in the event of a power outage.

[0056] Referring to Figures 1 to 6, in some embodiments, the drive mechanism further includes a mounting bracket 36, which is mounted on the wall 1. The output shaft 34 is rotatably connected to the mounting bracket 36, and the worm gear 342 is fixed to the mounting bracket 36 by a bracket 361.

[0057] The mounting bracket 36 can be fixed to the wall 1 in any way, for example, the mounting bracket 36 can be fixed to the wall 1 with screws. Alternatively, the mounting bracket 36 can be pre-installed in the wall 1.

[0058] In some embodiments, the worm gear 342 includes a mating portion that mates with the bracket 361, the bracket 361 is provided with a mating hole that mates with the mating portion, and the motor 343 is fixed to the bracket 361.

[0059] The worm 342 also includes a meshing part that mates with the worm wheel 341. Both ends of the meshing part have mating parts, and the meshing part and the mating parts are an integral structure. Furthermore, the meshing part and the mating parts are coaxially arranged.

[0060] In some embodiments, a rolling bearing is provided between the mating part and the mating hole, and the bracket 361 is fixed to the mounting bracket 36 by screws.

[0061] In some embodiments, the shaft 32 has a polygonal cross-sectional shape, and the sleeve 33 has an inner cavity that mates with the shaft 32, the inner cavity having a polygonal cross-sectional shape.

[0062] Referring to Figures 1 to 6, in some embodiments, there are multiple drive columns 353, which are evenly arranged along the circumference of the upper plate 351. The drive columns 353 and the upper plate 351 are an integral structure, and the cross-sectional shape of the drive column 353 is polygonal.

[0063] In some embodiments, the elastic element 355 is a spring, one end of the elastic element 355 is in contact with the lower plate 352, and the other end of the elastic element 355 is in contact with the sleeve 33.

[0064] In some embodiments, the elastic element 355 may not have a connection structure with the lower plate 352 and the sleeve 33. It is only necessary to ensure that both ends of the elastic element 355 are in contact with the upper plate 351 and the sleeve 33, respectively.

[0065] In some embodiments, the sleeve 33 can be rotatably connected to the wall 1 in any manner.

[0066] In some embodiments, when the lower end of the rotating shaft 32 protrudes from the sleeve 33, a rolling bearing may be provided between the lower end of the rotating shaft 32 and the wall 1 or the ground.
