Description

Technical Field

[0001] This utility model belongs to the field of door lock technology, and specifically relates to a lock for sightseeing vehicles. Background Technology

[0002] With the development of modern society and people's pursuit of a better quality of life, more and more people yearn to travel to pristine, unspoiled ecological environments, leading to the booming development of the tourism economy in various regions. As a common facility in tourist attractions, most sightseeing buses do not stop along their designated routes. If tourists get off the bus without permission or accidentally open the door, accidents may occur, endangering their lives and property.

[0003] However, existing sightseeing bus door locks, once engaged while the vehicle is in motion, can be opened from the inside by passengers. This poses a safety hazard as passengers could easily be accidentally opened by the switch. Therefore, it is necessary to design a special lock for sightseeing buses to solve this problem. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a special lock for sightseeing vehicles, thereby resolving the issues raised in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special lock for sightseeing vehicles, comprising:

[0006] Lock body;

[0007] A latch, which is rotatably connected to the bottom of the lock body, is used to connect with a latch.

[0008] A sliding piece, rotatably connected to the bottom of the lock body, is used for driving connection with the lock tongue;

[0009] An inner opening lever is rotatably connected to the side of the lock body and is used to pull the slider to rotate.

[0010] A limiting mechanism is provided to limit the movement of the inner opening tab.

[0011] Furthermore, the limiting mechanism is configured as an electromagnetic switch, which controls the extension and retraction of the iron core to limit the inner opening tab.

[0012] Furthermore, the sightseeing vehicle-specific lock also includes:

[0013] A baffle plate is connected to the inner opening tab, and the iron core is used to abut against the baffle plate.

[0014] Furthermore, the sightseeing vehicle-specific lock also includes:

[0015] A protrusion, which is connected to the locking tongue;

[0016] A lock housing, which is connected to the lock body, and an electromagnetic switch, which is connected to the lock housing;

[0017] A tactile switch is connected to the lock housing, and the protrusion is used to open the tactile switch.

[0018] Furthermore, the sightseeing vehicle-specific lock also includes:

[0019] A reed, which is connected to the tactile switch, and a protrusion that acts on the reed.

[0020] Furthermore, the sightseeing vehicle-specific lock also includes:

[0021] An outward-opening lever is rotatably connected to the lock housing and is used to pull the slider to rotate.

[0022] Furthermore, the sightseeing vehicle-specific lock also includes:

[0023] The torsion spring is connected to both the locking tongue and the sliding plate.

[0024] The technical effects and advantages of this utility model are as follows:

[0025] 1. By using a limiting mechanism to limit the inward opening lever, the inward opening lever cannot be rotated. This prevents the inward opening lever from causing the latch to separate from the lock by rotating the slide, thus preventing passengers from opening the sightseeing car door from the inside, which helps to improve safety.

[0026] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the mechanisms pointed out in the description and drawings. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0033] like Figure 1 and Figure 2As shown, a sightseeing vehicle lock according to an embodiment of this utility model includes a lock body 1, a latch 2, a slide 3, an inward-opening lever 4, and a limiting mechanism. Specifically, the lock body 1 is configured as a sheet structure with an L-shaped cross-section. The latch 2 is rotatably connected to the bottom of the lock body 1 and is used to connect with the latch. Specifically, when the lock body 1 is installed on the sightseeing vehicle body, the latch is installed on the sightseeing vehicle door; and when the lock body 1 is installed on the sightseeing vehicle door, the latch is installed on the sightseeing vehicle body. By using the latch 2 to lock the latch and the slide 3, the sightseeing vehicle door can be locked to the sightseeing vehicle body. The slide 3 is rotatably connected to the bottom of the lock body 1 and is used for a transmission connection with the latch 2. Specifically, a slot can be opened on the slide 3, and a corresponding locking block can be set on the latch 2. By rotating the slide 3, the locking block is inserted into the slot to limit the latch 2 and ensure the stability of the latch 2 and the latch engagement. The inward-opening lever 4 is rotatably connected to the side of the lock body 1, and is used to pull the slider 3 to rotate. Specifically, the inward-opening lever 4 is located on the inside of the sightseeing car door. When a passenger wants to open the sightseeing car door from the inside, by turning the inward-opening lever 4, the slider 3 is driven to rotate, so that the slider 3 no longer limits the locking tongue 2, causing the locking tongue 2 to separate from the latch, thus facilitating the opening of the sightseeing car door. The limiting mechanism is used to limit the inward-opening lever 4. Thus, by setting a limiting mechanism on the sightseeing car body, sightseeing car door, or lock body 1, and using the limiting mechanism to limit the inward-opening lever 4 so that the inward-opening lever 4 cannot rotate, it is possible to prevent the inward-opening lever 4 from driving the slider 3 to rotate and causing the locking tongue 2 to separate from the latch, thereby preventing passengers from opening the sightseeing car door from the inside, which is beneficial to improving security.

[0034] Optionally, such as Figure 1 As shown, to ensure the effectiveness of the limiting mechanism, an electromagnetic switch 5 is used. The electromagnetic switch 5 controls the extension and retraction of the iron core 6 to limit the inward opening lever 4. Specifically, when the sightseeing car door is closed and the latch 2 is connected to the latch, the electromagnetic switch 5 extends the iron core 6 to block the inward opening lever 4, thus limiting its movement and achieving a locked state. When it is necessary to open the sightseeing car door from the inside, the electromagnetic switch 5 retracts the iron core 6, releasing its limitation on the inward opening lever 4, allowing the inward opening lever 4 to move. This allows passengers to apply force to the inward opening lever 4 to unlock the latch 2 and latch.

[0035] Optionally, such as Figure 1 and Figure 2As shown, due to the limited internal structure of the lock body 1, after the electromagnetic switch 5 and the inner opening lever 4 are installed, there is a certain distance between the iron core 6 and the inner opening lever 4, making it difficult to guarantee that the iron core 6 can limit the inner opening lever 4 after it extends. To ensure that the iron core 6 can limit the inner opening lever 4, the sightseeing vehicle lock also includes a stop plate 7. The stop plate 7 is connected to the inner opening lever 4, and the iron core 6 is used to abut against the stop plate 7. Specifically, by setting the stop plate 7 on the inner opening lever 4, the stop plate 7 extends towards the side closer to the iron core 6, and the stop plate 7 can be set as a rectangular block or strip structure. By using the iron core 6 to abut against the stop plate 7, the stop plate 7 can be limited, thereby limiting the inner opening lever 4.

[0036] In this embodiment, the baffle 7 can be integrally formed with the inner opening lever 4, or it can be welded to the inner opening lever 4.

[0037] Optionally, such as Figure 1 and Figure 2 As shown, the sightseeing vehicle lock also includes a protrusion 8, a lock housing 9, and a tactile switch 10. The protrusion 8 is connected to the latch 2. Specifically, the protrusion 8 can be integrally formed with the latch 2 or welded to the latch 2. The lock housing 9 is connected to the lock body 1, and the electromagnetic switch 5 is connected to the lock housing 9. Specifically, the lock housing 9 can also be configured as an L-shaped plate structure. The latch 2, the slide 3, and the inner opening lever 4 are located between the lock housing 9 and the lock body 1. The tactile switch 10 is connected to the lock housing 9, and the protrusion 8 is used to open the tactile switch 10. Specifically, the tactile switch 10 is bolted to the outer left side of the lock housing 9, and the electromagnetic switch 5 is bolted to the outer right side of the lock housing 9. A control connection is established between the tactile switch 10 and the electromagnetic switch 5. Therefore, during the closing of the sightseeing vehicle door, the locking tongue 2 rotates, causing the protrusion 8 to rotate until the protrusion 8 acts on the tactile switch 10 to activate the tactile switch 10. The tactile switch 10 sends a signal to the button at the driver's seat control, which energizes the electromagnetic switch 5 connected to the button at the driver's seat control. This causes the iron core 6 of the electromagnetic switch 5 to pop out. At this time, the baffle 7 on the side of the inner opening lever 4 is blocked by the iron core 6 of the electromagnetic switch 5 and cannot move (if viewed from back to front, the inner opening lever 4 cannot move, that is, the inner opening lever 4 cannot rotate clockwise), thus achieving the locking state. A red light is displayed at the driver's seat control to indicate that it is in the locking state, preventing accidental activation.

[0038] When it is necessary to open, press the driver's seat control button. The button will turn green to indicate that the electromagnetic switch 5 is de-energized. The electromagnetic switch 5 will retract the iron core 6 under the action of the internal spring, so that the baffle 7 on the side of the inner opening lever 4 is no longer blocked by the iron core 6. The inner opening lever 4 can be pressed to pull the slider 3 (if the front view is from back to front, pressing the inner opening lever 4 will drive the inner opening lever 4 to rotate clockwise). The slider 3 will be released from the block of the latch 2, and the latch 2 will open and the lock will stop blocking the door, thus realizing the door opening action.

[0039] Optionally, such as Figure 1 As shown, since the protrusion 8 is connected to the latch 2 at the bottom of the lock body 1, and the tactile switch 10 is located on the left side of the lock case 9, the distance between the protrusion 8 and the tactile switch 10 is relatively far, making it difficult for the protrusion 8 to directly act on the tactile switch 10. The sightseeing vehicle lock also includes a spring 11. The spring 11 is connected to the tactile switch 10, and the protrusion 8 acts on the spring 11. Specifically, the spring 11 is configured as a rectangular strip structure, with its upper end connected to the tactile switch 10 and its lower end extending close to the protrusion 8. Thus, during the rotation of the latch 2, the protrusion 8 moves, causing the protrusion 8 to press the spring 11, and by pressing the spring 11, the button of the tactile switch 10 is pressed.

[0040] Optionally, such as Figure 1 As shown, the sightseeing vehicle lock also includes an outward-opening lever 12. The outward-opening lever 12 is rotatably connected to the lock housing 9 and is used to pull the slider 3 to rotate. Specifically, the outward-opening lever 12 is located on the outside of the lock housing 9. By pressing the outward-opening lever 12 and pulling the slider 3 (from top to bottom is the front view, so pressing the outward-opening lever 12 drives the outward-opening lever 12 to rotate clockwise), the slider 3 is released from the obstruction of the latch 2, and the latch 2 opens, thus realizing the door opening action.

[0041] Optionally, such as Figure 2 As shown, the existing locking tongue 2 and slide plate 3 use the same spring to pull each other, which has a short service life due to the need for constant tension. The sightseeing vehicle-specific lock also includes a torsion spring 13. The torsion spring 13 is connected to both the locking tongue 2 and the slide plate 3. Specifically, the torsion spring 13 is used to drive the locking tongue 2 and the slide plate 3 to reset. By installing torsion springs 13 on the locking tongue 2 and the slide plate 3 respectively, the locking tongue 2 and the slide plate 3 can be used normally even after multiple independent actions, resulting in a longer service life. At the same time, because the locking tongue 2 and the slide plate 3 are installed separately with torsion springs 13, they will not pull each other when the locking force is increased, thus preventing damage and malfunction of the sightseeing vehicle-specific lock.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
