[0056] The utility model discloses a locking device, which ensures the locking stability of the locking device to reduce potential safety hazards. In addition, the utility model also discloses a vehicle with the locking device.

[0057] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0058] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0059] like Figures 1 to 13 As shown, a locking device is disclosed in an embodiment of the present application, which is applied to open wagons including but not limited to railway transportation, and is used to lock the hinge of the lower side door of the open wagon with the body of the open wagon together to achieve locking of the lower side door.

[0060] Based on the above purpose, the locking device in the present application includes a buckle seat 100, a lock buckle 200 and a limiting assembly 300.

[0061] The buckle seat 100 has a slot 101, such as Figure 2 and Figure 7 The shape and size of the slot 101 can be set according to different opinions and are within the protection range. In some embodiments, an inclined surface is added at the entrance of the slot 101 to facilitate the locking buckle 200 to wedge in and penetrate the bottom of the slot 101 to prevent coal from accumulating at the bottom of the slot 101 and affecting the locking buckle 200 from entering the slot.

[0062] One end of the lock buckle 200 is rotatably connected to the buckle seat 100, and the other end can be inserted into the slot 101. When the lock buckle 200 is inserted into the slot 101, a restricted space is formed between the buckle seat 100 and the lock buckle 200. Taking an open car as an example, the restriction control can restrict the hinge so that the hinge cannot rotate, thereby locking the lower side door. The size and shape of the restricted space can be determined according to different needs and are all within the protection range.

[0063] It should be noted that the lock 200 includes a lock body 201 and a rotating shaft 202. One end of the lock body 201 can be inserted into the card slot 101, and the other end of the lock body 201 can be rotatably installed on the buckle seat 100 through the rotating shaft 202. The shape, size and material of the lock body 201 can be set according to different needs and are not limited here.

[0064] The limiting assembly 300 can limit the lock buckle 200 from rotating in a direction away from the card slot 101. When the lock buckle body 201 is engaged with the card slot 101, the locking device is in a locked state, and the limiting assembly 300 can limit the lock buckle 200 from rotating in a direction away from the card slot 101, that is, limit the lock buckle body 201 from rotating in a direction away from the card slot 101, so that the lock buckle body 201 is stably engaged in the card slot 101.

[0065] In the present application, a limit assembly 300 is added to limit the lock buckle 200 from rotating in a direction away from the card slot 101, so that the lock buckle 200 in the locked state can be stably engaged in the card slot 101, thereby achieving secondary locking, avoiding the problem of the lock buckle 200 being separated from the card slot 101 under the action of longitudinal force and vibration, and ensuring the stability of the locking device after locking.

[0066] Two specific structures of the limit assembly 300 are disclosed in the present application. It should be noted that the present application includes but is not limited to the disclosed specific structures of the limit assembly 300. As long as the limit assembly 300 can achieve the above-mentioned purpose, it is within the protection scope.

[0067] like Figures 1 to 5 The limiting assembly 300 disclosed in the illustrated embodiment includes a limiting seat 301 , a limiting rod 303 and a shifting rod 302 .

[0068] The limiting seat 301 is connected to the buckle seat 100 , and the limiting seat 301 has a locking position 3011 and a releasing position 3013 .

[0069] The limiting rod 303 is rotatable and movable along the axis direction of the limiting rod 303 and is installed on the limiting seat 301. The axis direction of the limiting rod 303 is parallel to the axis of the rotating shaft 202 of the lock buckle 200. The rotation angle of the limiting rod 303 and the moving distance of the limiting rod 303 are set as required.

[0070] In some embodiments, the limiting rod 303 is a round rod, and the distance between the axis of the limiting rod 303 and the axis of the lock body 201 is smaller than the distance required for the lock body 201 to rotate, that is, smaller than the distance between the axis of the lock body 201 and the edge of the rotating part of the lock body 201. Optionally, the limiting rod 303 abuts against the edge of the rotating part of the lock body 201.

[0071] The lever 302 is fixedly connected to the limiting lever 303. In some embodiments, the lever 302 and the limiting lever 303 are, but not limited to, an integral structure. When the limiting lever 303 moves to the locking position 3011, the limiting lever 303 abuts against the lock buckle 200 to limit the lock buckle 200 from rotating; and when the limiting lever 303 moves to the releasing position 3013, the limiting lever 303 separates from the lock buckle 200, and the lock buckle 200 can rotate.

[0072] Combination Figure 2 When the lever 302 is located at the locking position 3011, the limiting rod 303 abuts against the lock buckle 200, so that the limiting rod 303 limits the rotation of the lock buckle 200; Figure 5 As shown, when the lever 302 is located at the release position 3013, the limiting rod 303 is separated from the lock buckle 200. Optionally, the limiting rod 303 is away from the lock buckle 200, so that the lock buckle 200 can rotate.

[0073] When switching the position of the limit rod 303 , the user can change the position of the lever 302 by oscillating the lever 302 , that is, change the position of the limit rod 303 , realize the state switching of the limit assembly 300 , and finally realize the state switching of the locking device.

[0074] Combination Figure 3 As shown, the specific structure of the limiting seat 301 includes but is not limited to the following contents.

[0075] The limiting seat 301 and the buckle seat 100 are an integral structure, and the limiting seat 301 includes, in sequence along the axial direction of the limiting rod 303: a first flange (not shown in the figure), a second flange (not shown in the figure), a third flange (not shown in the figure) and a fourth flange (not shown in the figure).

[0076] Among them, the first flange, the second flange, the third flange and the fourth flange are all arc plate structures, and the first flange has a first through hole, the second flange has a second through hole, the third flange has a third through hole, and the fourth flange has a fourth through hole. The above-mentioned limiting rod 303 can move between the first through hole, the second through hole, the third through hole and the fourth through hole.

[0077] It should be noted that a locking position 3011 is formed between the second flange and the third flange, and a releasing position 3013 is formed between the third flange and the fourth flange. The shapes and sizes of the locking position 3011 and the releasing position 3013 can be set according to different needs.

[0078] In some embodiments, the limiting rod 303 can be inserted into three of the first through hole, the second through hole, the third through hole, and the fourth through hole. The length of the limiting rod 303 can only be inserted into three of the four through holes, that is, the limiting rod 303 has two positions, the first position is that the limiting rod 303 is inserted into the first through hole, the second through hole, and the third through hole; the second position is that the limiting rod 303 is inserted into the second through hole, the third through hole, and the fourth through hole.

[0079] In some embodiments, the lock body 201 of the lock 200 is rotatably installed between the first flange and the second flange. Specifically, the rotation shaft 202 passes through the first flange and the second flange, and the lock body 201 is inserted between the first flange and the second flange.

[0080] Therefore, when the limiting rod 303 is in the first position, the limiting rod 303 abuts against the lock body 201, thereby limiting the lock 200, preventing the lock 200 from reversing, and ensuring the locked state of the locking device. When the limiting rod 303 is in the second position, the limiting rod 303 is separated from the lock body 201, that is, the limiting rod 303 is not opposite to the lock body 201, and cannot limit the lock body 201, so the lock body 201 can rotate, so that the locking device can be opened.

[0081] Combination Figure 2 It can be seen that when the limit rod 303 is in the first position, the lever 302 is in the locking position 3011; Figure 5 As shown, when the limiting rod 303 is located at the second position, the shifting rod 302 is located at the releasing position 3013 .

[0082] Combination Figures 2 to 5 As shown, in order to enable the lever 302 to move between the locking position 3011 and the release position 3013, the edge of the third flange in the embodiment of the present application has a through groove 3012 connected to the third through hole, and the through groove 3012 passes through along the axial direction of the limiting rod 303 for the lever 302 to pass through.

[0083] In order to ensure the stability of the lever 302 in the locking position 3011 and prevent the limit rod 303 from rotating or moving, a magnetic member 304 is fixed at the locking position 3011 in some embodiments. The magnetic member 304 can be provided to magnetically adsorb the lever 302 to prevent the lever 302 from shaking during the operation of the vehicle, thereby affecting the stability of the locking device.

[0084] In some embodiments, when the lever 302 is located at the locking position 3011, the lever 302 is in a vertical downward state, at which time the lever 302 is adsorbed on the limit seat 301; when the lever 302 is located at the release position 3013, the lever 302 is in a horizontal state, and there is a platform at the release position 3013 to support the lever 302 and limit the rotation of the lever 302.

[0085] By arranging the lever 302 in different directions in different states, it is convenient for on-site personnel to judge the open or closed state of the limit assembly 300 .

[0086] Depend on Figure 2 Convert to Figure 5 During the process, the operator drives the lever 302 located in the locking position 3011 to rotate, so that the lever 302 changes from a vertical downward state to a horizontal state, aligns with the through slot 3012, passes through the through slot 3012 into the release position 3013, and is limited on the platform, completing the state switching of the limit assembly 300.

[0087] like Figures 6 to 13 The locking device disclosed in the figure includes a buckle seat 100 , a lock buckle 200 and a limiting assembly 300 .

[0088] The buckle seat 100 may be the buckle seat 100 disclosed in the above embodiment, and the buckle seat 100 may refer to the above disclosed content.

[0089] The lock buckle 200 includes a lock buckle body 201 and a rotating shaft 202 . The lock buckle 200 may refer to the lock buckle 200 disclosed in the above embodiment, except that the lock buckle body 201 in this embodiment has a groove 2011 .

[0090] The limiting assembly 300 includes: a housing 401 , a bottom plate 402 , a locking rod 404 and a driving assembly.

[0091] The housing 401 is fixedly connected to the buckle seat 100, and the bottom plate 402 is detachably connected to the lower edge of the housing 401. The housing 401 includes but is not limited to a cylindrical structure, and the housing 401 and the buckle seat 100 include but are not limited to an integral structure. The bottom plate 402 is connected to the lower edge of the housing 401 by a screw.

[0092] The above-mentioned locking pin rod 404 passes through the shell 401 and is threadedly connected to the bottom plate 402, and the locking pin rod 404 can move along the axial direction of the locking pin rod 404, and when the locking pin rod 404 moves to the first position, the first end of the locking pin rod 404 extends out of the shell 401 and is engaged with the groove 2011 of the lock buckle 200 to limit the position; when the locking pin rod 404 moves to the second position, the first end of the locking pin rod 404 is separated from the groove 2011 of the lock buckle 200.

[0093] In some embodiments, one end of the locking pin rod 404 has a pin head 408 , and the pin head 408 can be limited and separated from the groove 2011 during the movement of the locking pin rod 404 along the axial direction.

[0094] Since the locking pin rod 404 is threadedly connected to the bottom plate 402 , the locking pin rod 404 can move along its axial direction during the rotation of the locking pin rod 404 relative to the bottom plate 402 .

[0095] The driving assembly is connected to the second end of the locking pin rod 404 and drives the locking pin rod 404 to move along the axial direction.

[0096] The driving assembly drives the lock pin rod 404 to move along the axis direction of the lock pin rod 404 toward the direction close to the groove 2011, so that the pin head 408 of the lock pin rod 404 can be inserted into the groove 2011, thereby limiting the rotation of the lock buckle 200. When the driving assembly drives the lock pin rod 404 to rotate in the opposite direction, the lock pin rod 404 moves away from the groove 2011, so that the pin head 408 of the lock pin rod 404 can be disengaged from the groove 2011, and the lock buckle 200 can rotate.

[0097] In the present application, a limit assembly 300 is added to limit the lock buckle 200 from rotating in a direction away from the card slot 101, so that the lock buckle 200 in the locked state can be stably engaged in the card slot 101, thereby achieving secondary locking, avoiding the problem of the lock buckle 200 being separated from the card slot 101 under the action of longitudinal force and vibration, and ensuring the stability of the locking device after locking.

[0098] Figure 8 and Fig.11 The limiting assembly 300 also includes: an upper spring seat 4091, a lower spring seat 4092 and a spring 407.

[0099] The upper spring seat 4091 is connected to the pin head 408 in an axially limited manner. In some embodiments, the cross-sections of the pin head 408 and the locking pin rod 404 are both circular, and the diameter of the pin head 408 is larger than the diameter of the locking pin rod 404. The pin head 408 abuts against the upper surface of the upper spring seat 4091, and the locking pin rod 404 passes through the upper spring seat 4091. It should be noted that in some embodiments, the upper spring seat 4091 and the pin head 408 can also be fixedly connected.

[0100] The lower spring seat is fixedly connected to the bottom plate 402 ; two ends of the spring 407 are respectively against the upper spring seat 4091 and the lower spring seat 4092 .

[0101] During the process of rotating the locking pin rod 404, the locking pin rod 404 is threadedly connected to the bottom plate 402, and the bottom plate 402 is fixed, so the locking pin rod 404 will move along its axis. During the process of the locking pin rod 404 moving away from the groove 2011, the upper spring seat 4091 moves with the pin head 408 in the direction away from the groove 2011, that is, moves in the direction close to the lower spring seat 4092, until reaching the preset position. During this process, the spring 407 is continuously compressed, and the external force required to rotate the handle 406 is continuously increased until the pin head 408 is separated from the groove 2011. During the process of the locking pin rod 404 moving in the direction close to the groove 2011, the locking pin rod 404 drives the pin head 408 to move in the direction away from the lower spring seat 4092, and the compressed spring 407, under the action of its own restoring force, presses against the upper spring seat 4091 and moves with the pin head 408 in the direction close to the groove 2011 until the pin head 408 is stuck in the groove 2011.

[0102] In the present application, the spring 407 is provided to prevent the lock pin rod 404 from moving too far during movement. Instead, the external force required to rotate the handle 406 is gradually increased according to the compression force of the spring 407, and the approximate position of the pin head 408 is determined according to the continuous increase in the external force.

[0103] In some embodiments, the driving assembly includes: a handle 406 , a limiting member 405 and a blocking ring 403 .

[0104] The handle 406 is fixedly connected to the second end of the locking pin rod 404. In some embodiments, the handle 406 and the locking pin rod 404 are arranged vertically, and the handle 406 can be a rod.

[0105] The stopper 405 is fixedly connected to the bottom plate 402 and is used to limit the rotation of the handle 406. In some embodiments, the stopper 405 is an L-plate, and the handle 406 can be against the vertical plate of the L-plate and located above the L-plate, that is, the rotation of the handle 406 can be limited by the stopper 405 to maintain the stability of the locked position of the lock pin rod 404 and the groove 2011.

[0106] It should be noted that when the handle 406 is rotated to abut against the limiting member 405, the pin head 408 of the locking pin rod 404 is engaged with the groove 2011 to limit the position, so as to ensure the stability of the position of the locking pin rod 404 and the stability of the locked state of the locking device.

[0107] The shielding ring 403 is fixedly connected to the bottom plate 402 and is used to shield the second end of the locking pin rod 404. By providing the shielding ring 403, the exposed part of the locking pin rod 404 and the handle 406 can be protected to prevent external collisions from affecting the stability of the locking device.

[0108] Since the handle 406 rotates around the locking pin rod 404, and the shielding ring 403 is located on the outer ring of the locking pin rod 404, in order to ensure the rotation of the handle 406 and avoid interference between the handle 406 and the shielding ring 403, in the embodiment of the present application, the shielding ring 403 is set as a semicircular ring, such as Fig. 9 and Fig.13 As shown, the height of the shielding ring 403 to the bottom plate 402 gradually increases along the rotation direction of the handle 406, and the limiter 405 is located beside the minimum height end of the shielding ring 403, as shown in FIG. Figure 8 , Fig.11 and Fig.12 .

[0109] It should be noted that the above-mentioned blocking ring 403 also has a guiding function for guiding the rotation of the handle 406. In some embodiments, during the rotation of the handle 406, it can contact the blocking ring 403, and the height difference of the blocking ring 403 is used to guide the handle 406.
