Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to an outer lock component of a main lock for a side door of a high-speed railway driver's cab. Background Art

[0002] The driver's cab is the control center and information center of the entire train. It is not only the space where the operating console is located, but also the operating space for the operator, which is related to the driving safety of the entire rail vehicle.

[0003] The side door of the driver's cab of a train is mainly used to allow safe entry and exit of the driver's cab, and can achieve physical, thermal and sound isolation from the external environment. More importantly, it ensures the personal safety of the driver and passengers. The side door lock is an important component of the side door. During the main line operation, the failure of the door lock handle to reset will directly affect the switch and locking function of the driver's cab side door, and may even endanger the personal safety of the driver and passengers. In addition, the owners reported that in the early stage of trial operation of some high-speed railways, the side doors of the driver's cab failed to lock and were difficult to close. This caused vehicles to go offline and be delayed many times, which had a great impact on the main line operation. The side door of the driver's cab is an indispensable part of the high-speed rail door system. The rationality of the door lock scheme directly affects the efficiency of the driver in handling faults during the main line operation.

[0004] In order to ensure the convenience of opening and closing the side door of the driver's cab and to ensure safety and airtightness, China Patent Publication No. CN110541613A discloses an idle lock core and key, in which the movement of the push rod drives the I-shaped closed-hole block to close or open the keyhole, while unlocking or locking the blade, and the slider moves axially in the slider groove and rotates with the rotor to release the lock safety. However, when performing motion conversion, it is impossible to achieve precise control, resulting in inaccurate motion conversion; it is impossible to fully guarantee the safety and airtightness of the outer lock component; that is, the linkage part of the lock is not flexible enough, resulting in insufficient smooth motion conversion. Therefore, it is necessary to newly design an outer lock component of the main lock of the side door of the high-speed rail driver's cab. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a main lock outer side lock component for a side door of a high-speed railway driver's cab.

[0006] The technical solution of the utility model is:

[0007] A high-speed railway driver's cab side door main lock outer lock assembly includes a frame body, a push device installed on the frame body through a fixed rib, a swing arm device in contact with the push device, and a transmission device connected to the swing arm device, wherein the transmission device is slidably installed on the frame body, wherein:

[0008] The frame body includes an upper mounting frame and frames on both sides; the pushing device is located in the mounting frame through a fixed retaining edge installed on the frame;

[0009] The pushing device comprises a pushing frame and a pushing block installed on the upper back of the pushing frame; the top of the pushing block passes through the fixed shaft and is connected to the frame body through the fixed brackets on both sides, and the pushing frame is limited in the gap between the pushing block and the mounting frame; a reset spring is sleeved on the fixed shaft, and the reset spring is used to drive the pushing block to reset;

[0010] The swing arm device comprises an L-shaped swing arm, a movable slider located at the top of the L-shaped swing arm, and a fixed sleeve located at the bottom of the L-shaped swing arm, wherein the movable slider contacts the push block and drives the L-shaped swing arm to rotate around the fixed sleeve as the center; a compression spring is sleeved on the fixed sleeve, and the compression spring is used to apply a pre-tightening force to the L-shaped swing arm;

[0011] The transmission device includes a lower transmission plate connected to the L-shaped swing arm and an upper transmission plate connected to the lock core; the lower transmission plate is provided with a square steel interface connected to the inner lock square steel, and the upper transmission plate is provided with a plug-in part, the outer side of the plug-in part is linked to the lock core, and the inner side of the plug-in part is connected to the inner lock anti-lock knob.

[0012] This technical solution drives the swing arm device to rotate by the push device moving up and down, drives the inner lock square steel to rotate to realize the inner lock bolt, and realizes the switch action of the lock. By combining the push device and the swing arm device, a small push force can realize the switch action of the lock. The transmission device is used for the transmission of all linkage structures. The lower transmission plate synchronizes the rotation action of the swing arm device to the rotation action of the inner lock square steel in the square steel interface, thereby realizing the rotation of the inner lock handle and the oblique lock tongue; the upper transmission plate is used to fix the plug-in part, and the plug-in part synchronizes the key rotation action of the lock core to the rotation of the anti-lock knob of the inner lock, thereby realizing the unlocking state of the inner lock. In short, when the push device pushes hard, the push block will push the swing arm device to rotate, driving the movement of the square steel interface of the transmission device. The square steel interface on the lower transmission plate cooperates with the inner lock square steel, and the plug-in part on the upper transmission plate is linked with the lock core; this linkage mechanism ultimately realizes the opening or closing of the inner lock.

[0013] In some embodiments, a key is inserted into the lock core, and the plug-in portion is connected to the anti-lock knob of the inner lock to release the lock.

[0014] In this technical solution, the inner lock and anti-lock knob are used to lock and unlock the inner lock as a whole. When the anti-lock knob is turned, the handle and lock tongue of the inner lock cannot be used. Only when the anti-lock knob is unlocked, the handle and lock tongue can be opened and used. That is, first, the key needs to be inserted into the lock cylinder to unlock the inner lock first, and then the push device is used to move the handle and lock tongue.

[0015] In some embodiments, the push block is pressed downward, and the push block pulls the reset spring to extend, and the push block contacts the moving slider and drives the L-shaped swing arm to rotate; the square steel interface of the lower transmission plate drives the inner locking lock tongue through the inner locking square steel to realize the switching action of the lock.

[0016] In the present technical solution, the push block is movably arranged on the push frame, and the push block is used to convert the up and down pushing action into the rotation action of the L-shaped swing arm, and the inner lock square steel and the L-shaped swing arm are concentrically arranged on the same square steel interface, thereby driving the action of the handle and the lock tongue on the inner lock. When the push block is pressed down, the reset spring will stretch and store energy; once the pressure is released, the reset spring will release the stored energy and return the push block to its original position. It should be noted that the moving slider is actually a protrusion installed on the back of the push block, which moves synchronously with the push block. When it moves to a certain extent and contacts the sliding wheel at the top of the L-shaped swing arm, it drives the L-shaped swing arm to continue to rotate downward until the lock tongue and the handle completely open the inner lock, and then the push block can be released to reset.

[0017] In some embodiments, the push block is released, the reset spring pulls the push block to reset through the push block, the compression spring drives the L-shaped swing arm to reset, the inner lock square steel and the inner lock are linked to realize the lock tongue reset, and the key is turned to the locked position to complete the locking action of the lock.

[0018] In the present technical solution, after the push block is released and reset, the inner lock is locked by the key of the lock cylinder, thereby locking the entire lock; the push device, the swing arm device and the transmission device linkage structure are used to realize motion conversion and control the inner lock, fully ensuring the sealing and safety of the outer lock after locking.

[0019] In some of the embodiments, a shoulder for mounting a pushing device is provided on the fixed rib.

[0020] In this technical solution, the shoulder is used to limit the pushing frame within the installation frame, and is used for reliable cooperation between the pushing block and the L-shaped swing arm to achieve mechanical transmission of the pushing action, and adopt a lighter thrust to achieve the internal locking lock core and handle action.

[0021] In some embodiments, the movable slider is a protrusion installed on the pushing block, and a sliding wheel is arranged between the movable slider and the L-shaped swing arm, and the sliding wheel is in contact with the protrusion; the protrusion drives the sliding wheel to move downward, thereby driving the inner locking square steel at the hinge of the compression spring to rotate.

[0022] In this technical solution, a protrusion is integrated on the back of the push block, and a sliding wheel is integrated on the top of the L-shaped swing arm. In normal state, the two are always in a released state, and because the compression spring at the bottom of the L-shaped swing arm always provides a certain preload force to the sliding wheel, there is always a certain preload force pushing upward at the protrusion. Therefore, when the push block is pressed down, the thrust must be greater than the preload force to overcome the resistance of the compression spring and realize the downward pressing action of the push block.

[0023] In some embodiments, the lower transmission plate and the upper transmission plate are both fixed to the fixed rib by bolts at the end angles, and the lower transmission plate and the upper transmission plate are installed on the same side.

[0024] In the present technical solution, the lower transmission plate and the upper transmission plate are both installed on the fixed rib on the same side, and the edges between the lower transmission plate and the upper transmission plate are staggered with each other, further providing a firmness between them, and the original four bolts required are changed to only three bolts for fixing, thereby reducing costs and improving installation efficiency.

[0025] In some of the embodiments, a waterproof baffle is provided on the outer side of the lock core, and a sealing baffle is provided between the waterproof baffle and the lock core.

[0026] In this technical solution, the sealing ring is used to seal the lock core to prevent external moisture and dust from entering and affecting the life of the lock core; a magnetic attraction structure that cooperates with the installation frame is also provided on the waterproof baffle, and the magnetic attraction structure is used to further improve the sealing of the lock core.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] (1) The push device, swing arm device and transmission device linkage structure are used to realize motion conversion control of the inner lock, fully ensuring the sealing and safety of the outer lock after locking. It is safer and more reliable through lock core control.

[0029] (2) The lock linkage part realizes motion transformation through layout setting, so that the up and down horizontal movement of the pushing device is converted into the rotational movement of the swing arm device. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] like Figure 8 and Fig. 9 As shown, the technical solution pushes the swing arm device 4 to rotate by the pushing device 2 moving up and down, driving the inner lock square steel to rotate to realize the inner lock bolt, and realize the switch action of the lock. By combining the pushing device 2 with the swing arm device 4, a small pushing force can realize the switch action of the lock. The transmission device 5 is used for the transmission of all linkage structures. The lower transmission plate 54 synchronizes the rotation action of the swing arm device 4 to the rotation action of the inner lock square steel in the square steel interface 53, thereby realizing the rotation of the inner lock handle and the oblique lock tongue; the upper transmission plate 55 is used to fix the plug-in part 52, and the plug-in part 52 synchronizes the key rotation action of the lock core 51 to the rotation of the anti-lock knob of the inner lock, thereby realizing the unlocking state of the inner lock. In short, when the pushing device 2 is pushed hard, the pushing block 22 will push the swing arm device 4 to rotate, driving the movement of the square steel interface 53 of the transmission device 5. The square steel interface 53 on the lower transmission plate 54 cooperates with the inner lock square steel, and the plug-in portion 52 on the upper transmission plate 55 is linked with the lock core 51; this linkage mechanism ultimately realizes the opening or closing of the inner lock.

[0050] In this technical solution, the inner lock and anti-lock knob are used to lock and unlock the inner lock as a whole. When the anti-lock knob is turned, the handle and the lock tongue of the inner lock cannot be used. Only when the anti-lock knob is unlocked, the handle and the lock tongue can be opened and used. That is, first, the key needs to be inserted into the lock cylinder 51 to unlock the inner lock first, and then the push device 2 is used to move the handle and the lock tongue.

[0052] In the present technical solution, the push block 22 is movably arranged on the push frame 21. The push block 22 is used to convert the up and down pushing action into the rotation action of the L-shaped swing arm 42, and the inner lock square steel and the L-shaped swing arm 42 are concentrically arranged on the same square steel interface 53, thereby driving the action of the handle and the lock tongue on the inner lock. When the push block 22 is pressed down, the reset spring 23 will stretch and store energy; once the pressure is released, the reset spring 23 will release the stored energy to return the push block 22 to its original position. It should be noted that the movable slider 41 is actually a protrusion installed on the back of the push block 22, which moves synchronously with the push block 22. When it moves to a certain extent and contacts the sliding wheel at the top of the L-shaped swing arm 42, it drives the L-shaped swing arm 42 to continue to rotate downward until the lock tongue and the handle completely open the inner lock, and then the push block 22 can be released to reset.

[0055] like Figure 1 to Figure 2 As shown, the fixed rib 3 is provided with a shoulder for mounting the pushing device 2 .

[0056] In this technical solution, the shoulder is used to limit the pushing frame 21 within the installation frame 11, and to ensure reliable cooperation between the pushing block 22 and the L-shaped swing arm 42 to achieve mechanical transmission of the pushing action, and to use a lighter thrust to achieve the internal locking of the lock core 51 and the handle action.

[0057] like Figures 2 to 4 As shown, the movable slider 41 is a protrusion installed on the pushing block 22, and a sliding wheel is provided between the movable slider 41 and the L-shaped swing arm 42, and the sliding wheel is in contact with the protrusion; the protrusion drives the sliding wheel to move downward, thereby driving the inner locking square steel at the hinge of the compression spring 43 to rotate.

[0058] In the technical solution, a protrusion is integrated on the back of the push block 22, and a sliding wheel is integrated on the top of the L-shaped swing arm 42. In the normal state, the two are always in a released state, and because the compression spring 43 at the bottom of the L-shaped swing arm 42 always provides a certain preload force to the sliding wheel, there is always a certain preload force pushing upward at the protrusion. Therefore, when the push block 22 is pressed down, the thrust must be greater than the preload force to overcome the resistance of the compression spring 43 and realize the downward pressing action of the push block 22.

[0059] like Figure 1 , Figure 2 , Figure 5 , Figures 8 to 9 As shown, the lower transmission plate 54 and the upper transmission plate 55 are both fixed to the fixed rib 3 by bolts at the end angles, and the lower transmission plate 54 and the upper transmission plate 55 are installed on the same side.
