Description

Technical Field

[0001] The present application relates to the technical field of wind cabinet doors, and in particular to a double-door locking mechanism and a two-way opening and closing door using the same. Background Art

[0002] Wind cabinets are mainly used in air duct equipment, such as air conditioners, wind cabinet units, etc. They are often provided with inspection doors for inspecting internal equipment components.

[0003] The current inspection door is exemplified by the Chinese patent application CN219120659U previously filed by our company. The patent discloses an air conditioning box, characterized in that it comprises a box body, a centrifugal fan, a regulating unit, and a filter unit. The box body walls are a multi-layer sandwich structure, and the box body comprises a fresh air duct, a supply air duct, and a return air duct stacked in sequence. The internal dimensions of the fresh air duct, the supply air duct, and the return air duct increase progressively along the airflow direction. The box body is also provided with an inspection door, which is located adjacent to the filter unit and has a self-locking door handle. Specifically, one side of the inspection door is hinged to the box body, and the other side is locked and opened by a self-locking door handle.

[0004] With respect to the above-mentioned related technologies, the inventors found that once the above-mentioned inspection door is assembled, its opening position is determined to be able to open only in one direction, and the actual installation environment may affect the normal opening of the inspection door, thereby causing inconvenience to users. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a double-door locking mechanism, which has the advantage of being able to open and lock the door in both directions to facilitate personnel inspection.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0007] A double door locking mechanism, characterized by comprising a lock catch assembly and a lock button assembly cooperating with the lock catch assembly;

[0008] The lock assembly includes a base and a locking rod arranged on the base;

[0009] The lock button assembly includes a fixed seat, on which a fixed lock tongue and a movable lock tongue are provided. The fixed lock tongue is provided with an arc-shaped locking groove for engaging the lock rod, and the fixed seat is provided with a locking drive component for driving the movable lock tongue to be inserted under the arc-shaped locking groove to lock the lock rod in the arc-shaped locking groove.

[0010] To implement the above technical solution, the fixed lock tongue is first engaged with the lock rod, so that the lock rod is embedded in the arc-shaped engagement groove. Then, the locking driver drives the movable lock tongue to move and extend below the arc-shaped engagement groove, thereby locking the lock rod in the arc-shaped engagement groove. At this time, the lock button assembly as a whole can rotate around the lock rod but cannot be detached from the lock rod. In other words, after the door and the door frame are locked horizontally on both sides by the double door locking mechanism, when either double door locking mechanism is unlocked, the door can rotate around the lock rod of the other unlocked double door locking mechanism, thereby achieving the effect of opening the door from both sides, so that personnel can easily inspect internal components.

[0011] As a preferred solution of the present application, a sliding groove for the movable lock tongue to slide is provided on the fixing seat.

[0012] The above technical solution is implemented to ensure that the dynamic lock tongue does not deviate when sliding back and forth for a long time, thereby ensuring the stability of the locking.

[0013] As a preferred solution of the present application, the locking drive component includes a driving shaft rotatably arranged on a fixed seat, an eccentric cam is provided on the driving shaft, an elastic component for pressing the dynamic locking tongue against the eccentric cam is provided between the dynamic locking tongue and the fixed seat, and a driving cap for driving the eccentric shaft to rotate is provided on the driving shaft.

[0014] To implement the above technical solution, the driving cap drives the driving shaft to rotate, thereby driving the eccentric cam to rotate eccentrically, thereby abutting and driving the dynamic lock tongue to move horizontally along the slide groove and extend out of the fixed seat, and at the same time compressing the elastic member, thereby achieving the effect of driving the driving lock tongue to extend the locking lock assembly; when unlocking is required, it is only necessary to rotate the driving cap to drive the convex point of the eccentric wheel away from the dynamic lock tongue, and the dynamic lock tongue retreats into the slide groove under the action of the elastic member, thereby achieving the unlocking effect.

[0015] As a preferred solution of the present application, a polygonal groove is provided on the screw cap.

[0016] As a preferred solution of the present application, two lugs are provided on the base, and the locking rod is provided between the two lugs.

[0017] As a preferred solution of the present application, a guide surface is provided between the end of the fixed lock tongue and the arc-shaped snap-fit ​​groove.

[0018] The present application provides a two-way opening and closing door, comprising the above-mentioned double-door locking mechanism, a door frame and a door body, wherein the door frame and the door body are locked by the double-door locking mechanism.

[0019] As a preferred solution of the present application, at least two double-door locking mechanisms are provided, and the two double-door locking mechanisms are respectively provided on both sides of the door body.

[0020] As described above, this application includes at least one of the following beneficial technical effects:

[0021] 1. First, snap the fixed lock tongue onto the lock rod, allowing the lock rod to fit into the arc-shaped snap-fit ​​groove. Then, the locking actuator drives the movable lock tongue to extend below the arc-shaped snap-fit ​​groove, locking the lock rod in the arc-shaped snap-fit ​​groove. At this point, the entire lock button assembly can rotate around the lock rod but cannot be detached from the lock rod. In other words, after the door and door frame are horizontally locked by the double door locking mechanism on both sides, unlocking either double door locking mechanism allows the door to rotate around the lock rod of the other unlocked double door locking mechanism, thereby achieving double-sided door opening and facilitating access to internal components.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] Example 1

[0030] The embodiment of the present application discloses a double door locking mechanism. Figure 1The double-door locking mechanism includes a lock assembly 1 and a lock button assembly 2 that cooperates with the lock assembly 1.

[0031] The lock assembly 1 includes a base 11, on which two lugs 12 are provided. The two lugs 12 are integrally formed with the base 11, and a locking rod 13 is provided between the two lugs 12 so that the lock button assembly 2 can be buckled and locked on the locking rod 13.

[0032] The lock button assembly 2 includes a fixed base 21, on which a fixed lock tongue 22 and a movable lock tongue 23 are provided. The fixed lock tongue 22 is provided with an arc-shaped locking groove 24 for engaging the lock rod 13. The fixed base 21 is provided with a locking driver 25 for driving the movable lock tongue 23 to be inserted below the arc-shaped locking groove 24 to lock the lock rod 13 in the arc-shaped locking groove 24. That is, the fixed lock tongue 22 is first engaged with the lock rod 13, so that the lock rod 13 is embedded in the arc-shaped locking groove 24. Then, the locking driver 25 drives the movable lock tongue 23 to move and extend below the arc-shaped locking groove 24, thereby locking the lock rod 13 in the arc-shaped locking groove 24. At this time, the lock button assembly 2 as a whole can rotate around the lock rod 13, but cannot be detached from the lock rod 13. That is, after the door and door frame 3 are horizontally locked by the double door locking mechanism, when either double door locking mechanism is unlocked, the door can be rotated about the lock rod 13 of the other unlocked double door locking mechanism, thereby achieving the effect of opening the door from both sides, making it easier for personnel to inspect internal components. A guide surface 26 is provided between the end of the fixed lock tongue 22 and the arc-shaped engagement groove 24 to facilitate the engagement of the fixed lock tongue 22 with the lock rod 13.

[0033] The fixing seat 21 is provided with a sliding groove 27 for the movable lock tongue 23 to slide, so as to ensure that the movable lock tongue 23 will not deviate when sliding back and forth for a long time, thereby ensuring the stability of the locking.

[0034] The locking driver 25 includes a drive shaft 251 rotatably mounted on the fixed seat 21. An eccentric cam 252 is mounted on the drive shaft 251. An elastic member 253 is disposed between the dynamic lock tongue 23 and the fixed seat 21 for pressing the dynamic lock tongue 23 against the eccentric cam 252. A drive cap 254 is mounted on the drive shaft 251 for driving the eccentric shaft to rotate. Specifically, the drive cap 254 drives the drive shaft 251 to rotate, thereby driving the eccentric cam 252 to eccentrically rotate, thereby abutting and driving the dynamic lock tongue 23 to move horizontally along the chute 27 and out of the fixed seat 21, while simultaneously compressing the elastic member 253, thereby driving the dynamic lock tongue 23 out of the locked lock assembly 1. To unlock the lock, the drive cap 254 is simply rotated to move the eccentric wheel's protrusion away from the dynamic lock tongue 23. The dynamic lock tongue 23, under the action of the elastic member 253, retracts into the chute 27, thereby unlocking the lock.

[0035] In order to ensure that the dynamic lock tongue 23 can retreat quickly and normally, the elastic member 253 is configured as two springs, and the two springs are respectively arranged on both sides of the dynamic lock tongue 23 to ensure that the dynamic lock tongue 23 is subjected to uniform force.

[0036] The driving cap 254 is provided with a polygonal groove 255, thereby facilitating the effect of screwing the driving cap 254.

[0037] The implementation principle of a double door locking mechanism in the embodiment of the present application is as follows: first, the fixed lock tongue 22 is buckled onto the lock rod 13, so that the lock rod 13 is embedded in the arc-shaped buckling groove 24, and then the movable lock tongue 23 is driven by the locking driver 25 to move and extend below the arc-shaped buckling groove 24, thereby locking the lock rod 13 in the arc-shaped buckling groove 24. At this time, the lock button assembly 2 as a whole can rotate around the lock rod 13, but cannot be separated from the lock rod 13. That is, at this time, after the door and the door frame 3 are locked horizontally on both sides by the double door locking mechanism, when any of the double door locking mechanisms is unlocked, the door can rotate around the lock rod 13 of the other unlocked double door locking mechanism, thereby achieving the effect of opening the door on both sides, so as to facilitate personnel to inspect internal components.

[0038] Example 2

[0039] The present embodiment discloses a two-way door, comprising the aforementioned double-door locking mechanism, a door frame 3, and a door body 4. The door frame 3 and door body 4 are locked together by the double-door locking mechanism. At least two double-door locking mechanisms are provided, one on each side of the door body 4. This allows the door body 4 to open in both directions while ensuring smooth rotation.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
