[0001] The utility model belongs to the technical field related to elevators, and in particular relates to a door lock and an elevator door machine. Background Art

[0002] The elevator door machine is also called the "door opener", which is the opening and closing device of the elevator car door. The elevator door machine is usually equipped with a door lock, so that the elevator door machine can be locked on the door panel through the door lock to ensure that the elevator door will not open accidentally during the operation of the elevator car.

[0003] Among them, the door lock of the elevator door machine is connected to the electrical control system of the elevator door machine, which can automatically control the lifting and lowering of the lock tongue to achieve unlocking or locking. In addition, the door lock is also equipped with a manual unlocking structure, so that when the elevator fails, it can be manually opened by tools such as a hexagonal wrench to meet maintenance requirements. At present, the door locks of existing elevator door machines are usually large in size, complex in structure, high in cost, and inconvenient to install. Utility Model Content

[0004] In view of this, it is necessary to provide a door lock and elevator door machine that can meet both automatic locking and unlocking and manual unlocking functions and have a simple structure.

[0005] A door lock, comprising:

[0006] Fixed plate;

[0007] The door lock body comprises a main frame and a telescopic driving member installed on the main frame, a locking tongue is connected to the telescopic rod of the telescopic driving member, and the locking tongue can perform telescopic movement relative to the main frame under the drive of the telescopic driving member, so as to control the locking tongue to extend or retract from the fixing plate, and control the locking or unlocking of the door lock;

[0008] A lifting member is connected to the door lock body, and the door lock body can move relative to the fixed plate under the drive of the lifting member to control the lock tongue to retract or extend from the fixed plate.

[0009] It can be understood that the lifting piece is used to lift the door lock body as a whole to control the extension or retraction of the lock tongue on the fixed plate to achieve the purpose of manual unlocking or locking. Since the door lock body provides a large installation space for the lifting piece when assembling it, this can simplify the structure of the lifting piece and facilitate the assembly of the lifting piece to the door lock body, thereby reducing costs.

[0010] In one embodiment, the lifting member comprises a lifting horizontal plate, the lifting horizontal plate can be driven manually, and the lifting member can move relative to the fixed plate under the drive of the lifting horizontal plate;

[0011] Wherein, the lifting horizontal plate is arranged on one side of the telescopic driving member and is arranged perpendicular to the telescopic movement direction of the telescopic rod.

[0012] It can be understood that the lifting member is manually driven by a lifting horizontal plate located on one side of the telescopic driving member and perpendicular to the telescopic movement direction of the telescopic rod. In this way, it is easy for the external driving member to cooperate with the lifting member and realize the movement drive of the lifting member.

[0013] In one of the embodiments, a guide rod is connected to the fixed plate, a guide sleeve is connected to the main frame, and the guide rod passes through the main frame and slidably cooperates with the guide sleeve to guide the movement of the main frame on the fixed plate.

[0014] It is understandable that the sliding fit between the guide rod and the guide sleeve is used to guide the movement of the main frame on the fixed plate, which can prevent the lock tongue from deviating during the movement of the door lock body, thus avoiding interference between the lock tongue and the fixed plate, and has the effect of extending the service life of the lock tongue. Among them, the outer shape structure of the guide rod and the guide sleeve is not limited, such as the guide rod is not limited to a cylindrical rod, but can also be a square column rod or a rod body of other shapes; the guide sleeve structure is the same, and its outer shape or inner hole shape is not limited.

[0015] In one embodiment, the guide rod is arranged to pass through the guide sleeve, and a limiting member is connected to the portion of the guide rod passing through the guide sleeve;

[0016] Wherein, the guide rod is also provided with an elastic member, and the elastic member is respectively in contact with the limit member and the guide sleeve to drive the door lock body to reset elastically.

[0017] It is understandable that the elastic member is used to drive the elastic reset of the door lock body after the lifting member is released, so that the automatic reset of the door lock body after manual unlocking can be achieved.

[0018] In one of the embodiments, a limiting frame is also connected to the fixed plate, and a portion of the limiting frame extends into the main frame, and the portion of the limiting frame extending into the main frame can collide with the main frame during the upward movement to limit the stroke of the main frame when moving upward.

[0019] It can be understood that the limit frame is used to limit the travel of the main frame when it moves, so that the main frame can be prevented from being separated from the fixed plate as a whole, which has the effect of improving the stability of manual unlocking of the door lock.

[0020] In one embodiment, the door lock body further includes a trigger member, the trigger member partially extends into the main frame and is transmission-connected to the telescopic rod;

[0021] The fixing plate is provided with a trigger switch, and the trigger switch can be triggered by the trigger member and generate a feedback signal;

[0022] The trigger switch includes a first trigger switch and a second trigger switch;

[0023] When the door lock is locked, the first trigger switch can be triggered by the trigger member and generate a first feedback signal; when the door lock is unlocked, the second trigger switch can be triggered by the trigger member and generate a second feedback signal.

[0024] It can be understood that by utilizing the cooperation between the trigger switch and the trigger member, signal feedback of whether the lock tongue is locked or unlocked when the door lock is working can be achieved, which can meet the use requirements of the telescopic drive member for automatically controlling the telescopic movement of the lock tongue.

[0025] In one embodiment, the trigger member is mounted on the telescopic rod or the lock tongue, and is limited to the corresponding telescopic rod or the lock tongue at least along the movement direction of the trigger member, so that the trigger member and the lock tongue move synchronously; wherein a guide rod is provided on the main frame, and the guide rod passes through the trigger member to guide the movement of the trigger member relative to the main frame.

[0026] It is understandable that the trigger member can be directly fixedly connected to the telescopic rod or fixedly connected to the lock tongue, such as by fixing the trigger member thereon with a detachable structure, or by welding or integrally forming the trigger member thereon; or the trigger member can be locked to the telescopic rod or the lock tongue by plugging, snapping, etc., so that the trigger member moves synchronously when the telescopic rod drives the lock tongue to move. In addition, the specific form of the guide rod is not limited, such as the upper guide rod.

[0027] In one embodiment, the trigger is mounted on the telescopic rod and is pressed and limited to the lock tongue by a flange.

[0028] In one embodiment, the trigger is sleeved on the lock tongue and is clamped in the clamping groove of the lock tongue to form a limit position;

[0029] Wherein, a guide rod is arranged on the main frame, and the guide rod passes through the trigger member and is used for guiding the movement of the trigger member relative to the main frame.

[0030] It can be understood that the trigger member mounted on the telescopic rod is pressed and limited to the lock tongue by a flange, or the trigger member is directly clamped on the lock tongue; in this way, the trigger member can move along with the telescopic movement of the telescopic rod. In this process, the movement of the telescopic rod can be guided by the cooperation between the guide rod and the trigger member to ensure that the trigger member can trigger the first trigger switch and the second trigger switch during the movement.

[0031] In one embodiment, the fixing plate and the main frame are both configured as sheet metal parts.

[0032] It is understandable that by configuring the fixing plate and the main frame as sheet metal parts, the production cost of the fixing plate and the main frame can be reduced, and the difficulty of the processing technology can be reduced.

[0033] The present application also claims protection for an elevator door machine, comprising an elevator door machine body, and the door lock described above, wherein the door lock is installed in the elevator door machine body, and the lock tongue can be extended or retracted from the elevator door machine body;

[0034] Wherein, a triangular lock is rotatably connected to the elevator door machine body, and the triangular lock can drive the lifting member to move upward.

[0035] It is understandable that the triangular lock is used to manually unlock the door lock. By utilizing the structural characteristics of the triangular lock, the door lock can only be manually unlocked by a special tool, thus preventing passengers from misunderstanding the door lock.

[0036] In one embodiment, the elevator door machine further includes a fastener, which passes through the elevator door machine body and is threadedly connected to the fixing plate to fix the fixing plate into the elevator door machine body.

[0037] It can be understood that the assembly of the fixing plate in the elevator door machine body is achieved by using fasteners passing through the elevator door machine body, so that the assembly of the door lock in the elevator door machine body has a larger working space, which can facilitate the assembly of the door lock in the elevator door machine body.

[0038] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0039] The door lock and elevator door machine for which protection is sought in the present application use a lifting member to lift the door lock body as a whole to control the retraction or extension of the lock tongue on the fixed plate to achieve the purpose of manual unlocking or locking. Since the door lock body provides a large installation space for assembling the lifting member, this can simplify the structure of the lifting member and facilitate the assembly of the lifting member to the door lock body, thereby reducing costs.

[0048] The door lock 100 for which protection is requested in this application is applied in an elevator door machine 1000 .

[0049] like Figure 1 , Figure 2 As shown, the door lock 100 provided in one embodiment of the present application includes a fixed plate 10, a door lock body 20 and a lifting member 30. The door lock body 20 includes a main frame 21 and a telescopic driving member 22 installed on the main frame 21. A lock tongue 23 is connected to the telescopic rod 221 of the telescopic driving member 22, and the lock tongue 23 can make a telescopic movement relative to the main frame 21 under the drive of the telescopic driving member 22, so as to control the lock tongue 23 to extend or retract from the fixed plate 10 and control the locking or unlocking of the door lock 100; the lifting member 30 is connected to the door lock body 20, and the door lock body 20 can move or move downward relative to the fixed plate 10 under the drive of the lifting member 30, so as to control the lock tongue 23 to retract or extend from the fixed plate 10. That is to say, when the door lock 100 is working, the telescopic driving member 22 can be used to realize automatic locking or unlocking, and the lifting member 30 can also be used to realize manual unlocking or locking. Here, the power mechanism of the telescopic driving member 22 can be set to be driven by an electric push rod, a hydraulic cylinder, etc.

[0050] It can be understood that the lifting member 30 is used to lift the door lock body 20 as a whole to control the retraction or extension of the lock tongue 23 on the fixed plate 10 and achieve the purpose of manual unlocking or locking. Since the door lock body 20 provides a large installation space for the lifting member 30 when assembling it, this can simplify the structure of the lifting member 30 and facilitate the assembly of the lifting member 30 to the door lock body 20, thereby reducing costs.

[0051] In one embodiment, the fixing plate 10 is configured as a sheet metal part, and specifically can be formed by bending a flat plate. This can facilitate the production and preparation of the fixing plate 10 and has the effect of reducing the production cost of the fixing plate 10 .

[0052] In one embodiment, the main frame 21 is also configured as a sheet metal part, and specifically, a gantry structure formed by bending a flat plate can be used to facilitate the production and preparation of the main frame 21, which has the effect of reducing the production cost of the main frame 21. Here, the main frame 21 is configured as a C-shaped structure, and the main frame 21 has a first bending plate 212 and a second bending plate 213, and through holes are provided on the first bending plate 212 and the second bending plate 213, and the through holes can be used for the telescopic rod 221 of the telescopic driving member 22 to pass through; wherein, the first bending plate 212 is attached to the fixed plate 10 and supported on the fixed plate 10, and the second bending plate 213 is connected to the body 222 of the telescopic driving member 22, and is used to carry the telescopic driving member 22.

[0053] like Figure 1 , Figure 2 As shown, in one embodiment, the lifting member 30 includes a lifting horizontal plate 31, which can be manually driven, and the lifting member 30 can move relative to the fixed plate 10 under the drive of the lifting horizontal plate 31, wherein the lifting horizontal plate 31 is arranged on one side of the telescopic driving member 22 and is arranged perpendicular to the telescopic movement direction of the telescopic rod 221. The lifting member 30 can be driven to move by pushing the lifting horizontal plate 31, so that the external driving member can cooperate with the lifting member 30 and drive the lifting member 30 to move. Here, the lifting member 30 can also be set as a sheet metal member.

[0054] like Figure 1 , Figure 2 As shown, in this embodiment, here, the lifting member 30 also includes a first extension plate 311, and the first extension plate 311 is abutted against the second bending plate 213 of the main frame 21 and connected to the second bending plate 213; wherein, the first extension plate 311 and the second bending plate 213 can be fixed by bolts, screws and other fasteners (not shown) to fix the lifting member 30 to the main frame 21; at the same time, the lifting member 30 is also abutted against the body 222 of the telescopic driving member 22. In order to improve the stability of the lifting member 30 driving the door lock body 20 to move, the telescopic driving member The side of the body 222 of the lifting member 22 away from the lifting member 30 is also provided with an auxiliary plate 32 abutting against the body 222 of the telescopic driving member 22, and a second extension plate 321 is formed on the auxiliary plate 32, and the second extension plate 321 abuts against the second bending plate 213 of the main frame 21 and is connected to the second bending plate 213; wherein, a connecting rod 33 penetrating the fixed block 2221 fixed to the body 222 of the telescopic driving member 22 is connected between the auxiliary plate 32 and the lifting member 30, so that the lifting member 30 can simultaneously drive the main frame 21 and the telescopic driving member 22 during the movement. In order to facilitate the adjustment of the installation position, the installation holes on the first extension plate 311 and the second extension plate 321 preferably adopt a long slot hole structure.

[0055] like Figure 1 , Figure 2 As shown, in one embodiment, a guide rod 41 is connected to the fixed plate 10, and a guide sleeve 42 is connected to the main frame 21. The guide rod 41 passes through the main frame 21 and slides with the guide sleeve 42 to guide the movement of the main frame 21 on the fixed plate 10. In other words, the sliding cooperation between the guide rod 41 and the guide sleeve 42 can guide the upward or downward movement of the main frame 21 on the fixed plate 10, so that the lock tongue 23 is prevented from deviating during the upward or downward movement of the door lock body 20. In this way, interference between the lock tongue 23 and the fixed plate 10 can be avoided, which has the effect of extending the service life of the lock tongue 23.

[0056] Preferably, the guide rods 41 are symmetrically arranged on both sides of the telescopic rod; in one embodiment, there are two guide rods 41, and correspondingly, there are two guide sleeves 42, so that the door lock body 20 is guided by multiple guide rods 41 during the lifting and lowering process on the fixed plate 10. Here, the number of guide rods 41 can also be three, four, or even more, which will not be elaborated here.

[0057] In this embodiment, the guide rod 41 is arranged through the guide sleeve 42, and the guide rod 41 is connected to the limit member 411 on the part passing through the guide sleeve 42; wherein, the guide rod 41 is also provided with an elastic member 43, and the elastic member 43 abuts against the limit member 411 and the guide sleeve 42 respectively, and is used to drive the door lock body 20 to elastically reset, so that the door lock body 20 can be automatically reset after being manually unlocked. Here, the elastic member 43 is a spring, or other rubber sleeves with high elasticity. It should be noted that the above-mentioned limit member 411 can be specifically configured as a screw 4112 or a bolt connected with a gasket 4111, and the screw 4112 or the bolt passes through the gasket 4111 and is threadedly connected to the guide rod 41, so as to fix the limit member 411 to the guide rod 41, and the gasket 4111 is used to abut against the elastic member 43. A through hole for the guide rod 41 to pass through is provided on the upper end surface of the main frame 21, i.e., the second bending plate 213. When the door lock is working normally, the telescopic drive member 22 drives the lock tongue to move up and down, and the elastic member 43 does not move accordingly. Only when the door lock is manually unlocked, the unlocking process will drive the elastic member 43 to move, thereby reducing the consumption of the elastic member 43 and extending its service life.

[0058] like Figure 1 , Figure 2As shown, in one embodiment, the fixed plate 10 is further connected to a limiting frame 51, and a portion of the limiting frame 51 extends into the main frame 21, and the portion of the limiting frame 51 extending into the main frame 21 can collide with the moving main frame 21 to limit the travel of the main frame 21 when it moves, thereby achieving the limitation of manual unlocking of the door lock body 20, so that the main frame 21 can be prevented from being separated from the fixed plate 10 as a whole, which has the effect of improving the stability of manual unlocking of the door lock 100. Here, the limiting frame 51 can specifically limit the travel of the main frame 21 when it moves by abutting against the guide sleeve 42 fixedly connected to the main frame 21.

[0059] like Figure 1 , Figure 2 As shown, in this embodiment, the limiting frame 51 includes a lower end plate 511, an upper end plate 512 and a connecting plate 513 for connecting the lower end plate 511 and the upper end plate 512, and a Z-shaped structure is formed between the lower end plate 511, the upper end plate 512 and the connecting plate 513. The lower end plate 511 is attached to the fixing plate 10, leaving an L-shaped space for fasteners to be assembled on the fixing plate 10, specifically, the bolt and nut assembly 501 is used to fix it, and the upper end plate 512 partially extends into the main frame 21, wherein one end surface of the upper end plate 512 extending into the main frame 21 is set as an inner concave arc surface 5121, and the structural characteristics of the inner concave arc surface 5121 can be used to avoid the guide rod 41 and the sleeve portion 421 of the guide sleeve 42, and then the collision between the base portion 422 of the guide sleeve 42 and the upper end plate 512 is used to limit the movement stroke of the guide sleeve 42 when following the main frame 21 to move upward. Here, the limiting frame 51 is also configured as a sheet metal part; and the guide sleeve 42 is configured as a flange bearing.

[0060] like Figure 1 , Figure 2 As shown, in one embodiment, the door lock body 20 further includes a trigger member 24, which partially extends into the main frame 21 and is transmission-connected to the telescopic rod 221; a trigger switch 60 is provided on the fixing plate 10, and the trigger switch 60 can be triggered by the trigger member 24 and generate a feedback signal, so that the signal feedback when the lock tongue 23 moves when the door lock 100 is working can be realized. Here, the trigger switch 60 and the limit frame 51 are arranged on both sides of the main frame 21, so that the entire door lock structure is compact and reasonable. Among them, the trigger switch 60 can be specifically set as a micro switch, a proximity switch, a photoelectric sensor switch, etc.

[0061] like Figure 1As shown, in one embodiment, the trigger member 24 is sleeved on the telescopic rod 221, and is pressed and limited to the lock tongue 23 by a flange (not shown), so that the telescopic rod 221 can drive the trigger member 24 to move up synchronously through the lock tongue 23 during the retraction process, and the telescopic rod 221 can drive the trigger member 24 to move down synchronously through the flange during the extension process. In another embodiment, the trigger member 24 is sleeved on the lock tongue 23, and is clamped in the clamping groove of the lock tongue to form a limit, and moves synchronously with the lock tongue 23. The trigger member 24 includes a trigger arm body, and one end of the trigger arm body is provided with a connecting arm extending toward the main frame 21, and the connecting arm is used to connect with the telescopic rod 221 or the lock tongue 23 to form a synchronous movement. Among them, a guide rod 211 is provided on the main frame 21, and the guide rod 211 is arranged through the trigger member 24, and is used to guide the movement of the trigger member 24 relative to the main frame 21, so as to ensure that the trigger member 24 can trigger the trigger switch 60 during the movement.

[0062] like Figure 1 , Figure 2 As shown, in this embodiment, the trigger switch 60 includes a first trigger switch 61 and a second trigger switch 62. When the door lock 100 is locked, the first trigger switch 61 can be triggered by the trigger member 24 and generate a first feedback signal; when the door lock 100 is unlocked, the second trigger switch 62 can be triggered by the trigger member 24 and generate a second feedback signal. In other words, this embodiment can use the first trigger switch 61 and the second trigger switch 62 to realize signal feedback when the lock tongue 23 is locked in place or unlocked in place, so as to meet the use requirement of the telescopic drive member 22 to automatically control the telescopic movement of the lock tongue 23.

[0063] like Figure 1 , Figure 2As shown, the trigger member 24 of this embodiment also includes a trigger end, and the trigger end and the connecting arm are respectively located on both sides of the trigger arm body, and the trigger end includes a first trigger end 241 and a second trigger end 242. The first trigger end 241 can be contacted and connected with the first trigger switch 61 by means of a pin, and the second trigger end 242 can be connected with the second trigger switch 62 by means of induction. The first trigger end 241 extends axially along the trigger arm body to a position corresponding to the first trigger switch 61, and the second trigger end 242 extends from the trigger arm body toward the main frame 21 through bending to a position corresponding to the second trigger switch 62. When the telescopic rod 221 drives the lock tongue 23 to extend from the fixed plate 10 to lock with the door panel, the telescopic rod 221 can simultaneously drive the first trigger end 241 on the trigger member 24 to insert into the first trigger switch 61, and trigger the first trigger switch 61, so that signal feedback when the lock tongue is locked in place can be realized; and when the telescopic rod 221 drives the lock tongue 23 to retract from the fixed plate 10 to unlock with the door panel, the telescopic rod 221 can simultaneously drive the second trigger end 242 on the trigger member 24 to move to the sensing position of the second trigger switch 62, and trigger the second trigger switch 62, so that signal feedback when the lock tongue is unlocked in place can be realized.

[0064] like Figure 3 As shown, the present application also provides an elevator door machine 1000, including an elevator door machine body 200 and the door lock 100 described above, the door lock 100 is installed in the elevator door machine body 200, and the lock tongue 23 can be extended or retracted from the elevator door machine body 200.

[0065] like Figure 3 As shown, in one embodiment, a triangular lock 210 is rotatably connected to the elevator door machine body 200, and the triangular lock 210 can drive the lifting member 30 to move upward. That is to say, when the elevator door machine 1000 is in use, the triangular lock 210 can be driven to rotate to realize the control of manual unlocking of the door lock 100. In this way, the structural characteristics of the triangular lock 210 are utilized, so that the door lock 100 can only be manually unlocked by a special tool, so that the passengers can be prevented from mistaking the door lock 100. It should be noted that when the triangular lock 210 releases the upward drive of the lifting member 30, the door lock body 20 and the lifting member 30 can automatically move downward under the action of gravity.

[0066] In one embodiment, the elevator door machine 1000 further includes a fastener (not shown), which passes through the elevator door machine body 200 and is threadedly connected to the fixing plate 10 to fix the fixing plate 10 to the elevator door machine body 200. That is, when the door lock 100 is assembled in the elevator door machine body 200, the fastener can be fastened on the outer knob of the elevator door machine body 200, so that the assembly of the door lock 100 in the elevator door machine body 200 has a larger working space, so that the assembly of the door lock 100 in the elevator door machine body 200 can be facilitated. Here, the fastener is set as a screw or a bolt.

[0067] In summary, the door lock 100 and the elevator door machine 1000 for which protection is sought in the present application use the lifting member 30 to lift the door lock body 20 as a whole to control the retraction of the lock tongue 23 on the fixed plate 10 and achieve the purpose of manual unlocking. Since the door lock body 20 provides a large installation space for the lifting member 30 when assembling it, the structure of the lifting member 30 can be simplified and it is convenient to assemble the lifting member 30 to the door lock body 20, thereby reducing costs.

[0068] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
