[0040] For transportation equipment, the stability and safety of the door body are important considerations during design. In the related art, the door body of transportation equipment is often provided with a limit block to buffer when the door is closed or to limit the position after the door is closed.
[0041] However, the limiting structures in the related art have certain limitations, especially in ensuring the stability of the door body after closing. Specifically, although the door body is designed with a limiting block, in some cases, the free end of the door body may still shake after being inserted into the limiting structure. For example, after the free end of the rear door of a van is fixed by a latch, it sometimes still shakes. This shaking not only affects the comfort of passengers and the operational safety of transportation equipment, but may also cause premature wear or damage to the door body and its accessory components, thereby increasing maintenance costs and potential repair needs.
[0042] Therefore, the utility model provides a lock structure to improve the stability of the door when it is closed.
[0043] See also Figures 1 to 3In one embodiment of the utility model, the lock structure includes a limit assembly 100 and a snap assembly 200; the limit assembly 100 includes a limit member 110, which can be a cylindrical pin or a conical pin; one end of the limit member 110 is used to be installed on the door body 300, and the limit member 110 and the door body 300 can be connected by bolts or snaps. The snap assembly 200 includes a snap base 210, and a limit hole 220 is provided on the snap base 210; the snap base 210 is used to connect with the door body 300, and at this time, the snap base 210 and the door body 300 can also be connected by bolts or snaps; the snap base 210 can also be used to be set as a bearing compartment of a traffic equipment or a part of another door body 300, and at this time, the snap base 210 can be formed by the shell edge of the bearing compartment of the traffic equipment close to the door body 300, or by the frame of another door body 300. The limiting hole 220 is used for the other end of the limiting member 110 to extend therein, and the limiting hole 220 is used to limit the movement of the limiting member 110 along two intersecting radial directions. The two intersecting radial directions are two directions that pass through the axis of the limiting hole 220 and are not parallel, and can be two directions that are perpendicular to each other, or two directions that form a certain angle; this embodiment does not limit this, so as to achieve the ability to limit the movement of the limiting member in more radial directions of the limiting hole. In this way, when the door body 300 is closed, the limiting member 110 will be snapped into the limiting hole 220; since the limiting hole 220 is used to limit the movement of the limiting member 110 along two intersecting radial directions, the movement of the limiting member and the corresponding door body 300 can be limited in more radial directions of the limiting hole 220, thereby reducing the shaking of the door body 300 connected to the limiting member 110, so as to improve the stability of the door body 300 when it is closed.
[0044] For a van, the distance from the rotating end to the free end of its door is long, and the rotation range when closing is large; therefore, its limiting structure is generally configured to include a limiting groove and a limiting member latch, and the side wall of the limiting groove is provided with a notch; the notch is directly opposite to the side wall of the latch, and the width of the notch is greater than the width of the latch to form an escape space, so that the latch can smoothly follow the door to swing in the closing direction without being hindered by the side wall of the limiting groove. Accordingly, although the setting of such a limiting groove can reduce the risk of the latch hitting the side wall of the limiting groove, the latch still moves in the limiting groove because the portion of the latch corresponding to the notch lacks the abutment of the limiting groove, thereby causing the door to shake. Unlike the door of a van, in some embodiments of the present application, the lock structure can be used for a door body 300 with a smaller swing range at the free end. In the related art, the door body 300 of some transportation equipment is relatively short from the shell of the transportation equipment, so the swing amplitude of the free end of the door is relatively small when it is closed; for example, the storage compartment of some transportation equipment is composed of a three-door structure, and the transportation equipment includes a top door 310. The distance between the top door 310 and the shell of the transportation equipment used for closing is relatively short. When it is closed, the path that the free end of the top door 310 needs to pass through is also shortened accordingly, and correspondingly, the swing amplitude is smaller. Since the swing amplitude of the free end of the door is relatively small, the required avoidance space is also correspondingly smaller; therefore, setting the limiting structure as the limiting hole 220 and the limiting member 110 can form a better limiting effect on the door, reduce the shaking of the door, and also reduce the risk of the limiting member 110 hitting the limiting hole 220.
[0045] Specifically, in some embodiments, see Figure 6 The limiting hole 220 includes a guide section 221 and a limiting section 222 that are connected to each other. The clamping base 210 has a mating surface 223 facing the limiting assembly 100. The guide section 221 extends to the mating surface 223. The limiting section 222 is arranged on the side of the guide section 221 away from the mating surface 223. The aperture of the guide section 221 decreases along the direction from the mating surface 223 to the limiting section 222. For example, the guide section 221 can be set to a cone shape, a trumpet shape or a bowl shape, which is not limited in this embodiment. In the process of clamping the limiting member 110 to the clamping base 210, the limiting member 110 first contacts the mating surface 223. Since the aperture of the guide section 221 is larger, it allows the limiting assembly 100 to enter the clamping base 210 smoothly. As the limiting member 110 is further inserted, the aperture gradually decreases until it reaches the limiting section 222, at which time the limiting assembly 100 is fixed in place. Such a configuration not only facilitates alignment and insertion, but also helps to provide a better limiting effect for the limiting member 110 .
[0046] Further, in one embodiment, continue to refer to Figure 6, along the direction from the mating surface 223 to the limiting section 222, the reduction range of the aperture of the guide section 221 gradually increases, for example, the guide section 221 is configured to be trumpet-shaped. That is, the diameter of the end of the limiting section 222 close to the mating surface 223 is larger and more gentle. Such a configuration can facilitate the limiting member 110 to enter the limiting hole 220, and as the aperture gradually decreases, the limiting member 110 is introduced into the limiting section 222.
[0047] In some embodiments, the side wall where the limiting hole 220 is located is set to be closed along the circumferential direction, or the side wall where the limiting hole 220 is located is provided with an opening in the circumferential direction and the width of the opening is less than the width of the limiting member 110 (not shown in the drawings). When the limiting hole 220 is provided on the side wall of the clamping base 210, the side wall of the limiting hole 220 can be completely closed along the circumferential direction, that is, there is no opening around the limiting hole 220, forming a continuous annular structure; the side wall of the limiting hole 220 can also be provided with one or more openings in the circumferential direction, but the width of the opening is less than the width of the limiting member 110, so as to prevent the limiting member 110 from escaping from the opening and ensure that the limiting member 110 can be limited in the limiting hole 220. Such a setting can play the role of limiting the limiting member 110 on the limiting hole 220.
[0048] In some embodiments, the locking structure includes a first protective member (not shown in the drawings) for being arranged between the clamping base 210 and the door body 300, and / or the locking structure includes a second protective member (not shown in the drawings) for being arranged between the stopper 110 and the door body 300. When the clamping base 210 is installed to the door body 300, or the stopper 110 is installed to the door body 300, it may cause scratches on the paint surface of the door body 300, thereby causing rust and affecting the service life of the traffic equipment. Therefore, the first protective member and the second protective member are provided to protect the paint surface. The first protective member and the second protective member can be spacers of the black steel paper gasket type, or they can be spacers of the type of plastic gaskets.
[0049] In some embodiments, see Figure 4 and Figure 5The limiting assembly 100 further includes a first buffer 120, which is disposed on the outer side wall of the limiting assembly 110 and is used to abut against the clamping base 210. When the limiting assembly 110 is inserted into the limiting hole 220 of the clamping base 210, the first buffer 120 can be used to abut against the clamping base 210, thereby providing a buffering effect, reducing the impact and noise that may be generated by the direct contact between the limiting assembly 100 and the clamping base 210, and reducing the wear of the limiting assembly 110 and the clamping base 210; thereby improving the stability and reliability of the locking structure. The first buffer 120 can be made of a soft material or an elastic material, such as rubber, silicone, polyurethane foam or other materials with good buffering properties. The first buffer 120 can be annular, tubular or any other shape to adapt to the shape of the limiting assembly 110. In one embodiment, the first buffer 120 is detachably connected to the outer side wall of the limiting assembly 110, for example, by snapping, screwing, etc. In this way, the first buffer member 120 can be set to a variety of different models, so that different models of first buffer members 120 can be matched according to different door structures, expanding the application range of the first buffer member 120. Optionally, the first buffer member 120 includes a sleeve section 121, which is sleeved on the outer side wall of the stop member 110 to provide uniform buffering force in the circumferential direction.
[0050] In some embodiments, continue to refer to Figure 4 and Figure 5 The limiting assembly 100 further includes a second mounting plate 130, which is used to be connected to the door body 300, and the limiting member 110 is installed on the second mounting plate 130. The limiting member 110 can be installed on the mounting plate 130 by bolting or welding. The second mounting plate 130 protrudes toward the clamping assembly 200 to form a protrusion 131, and the limiting member 110 is connected to the protrusion 131. The setting of the protrusion 131 is conducive to improving the overall structural strength of the second mounting plate 130 and reducing the direct impact between the part of the second mounting plate 130 other than the protrusion 131 and the clamping base 210 during clamping.
[0051] In some embodiments, see Figure 5 The first buffer 120 includes a sleeve section 121, and a connecting plate 122 is provided on one side of the first buffer 120 close to the second mounting plate 130; the connecting plate 122 is provided with a connecting through hole, the stopper 110 passes through the connecting through hole and extends into the sleeve section 121, and the connecting plate 122 is used to abut against the end of the protrusion 131. That is, the first buffer 120 provides a more uniform buffer force through the arrangement of the sleeve section 121; and the sleeve section 121 is connected to the second mounting plate 130 through the connecting plate 122, so as to improve the stability of the first buffer 120 and prevent the first buffer 120 from being dislocated during operation.
[0052] In some embodiments, see Figure 5 The locking structure also includes a buffer sleeve 230, which is sleeved on the clamping base 210. The buffer sleeve 230 can provide buffering when the limiter 110 is inserted into or contacts the clamping base 210, reduce impact and vibration, and protect the clamping base 210 and the limiter 110 from damage. In addition, the buffer sleeve 230 can also prevent interference and cause friction and abnormal noise. The buffer sleeve 230 can be fixed to the clamping base 210 by bonding, snapping, tightening or threading to ensure that the buffer sleeve 230 maintains a stable position during operation. In one embodiment, the buffer sleeve 230 can be set as a rubber sleeve.
[0053] In some embodiments, see Figure 4 and Figure 5 The clamping base 210 includes a first mounting plate 211 and a clamping plate 212. The first mounting plate 211 is used to connect with the load-bearing cabin of the traffic equipment or another door body 300; the clamping plate 212 is connected to the first mounting plate 211, and the clamping plate 212 and the first mounting plate 211 can be set to be integrally formed or connected by welding; the limiting hole 220 is set on the clamping plate 212, and the buffer sleeve 230 is sleeved on the clamping plate 212. By setting the clamping base 210 to include two plate structures of the first mounting plate 211 and the clamping plate 212, the convenience of assembly can be improved. Further, in one embodiment, the buffer sleeve 230 is provided with an avoidance hole 231, and the avoidance hole 231 is connected with the limiting hole 220, so that the limiting member 110 is inserted into the limiting hole 220 through the avoidance hole 231, thereby reducing the impact of the limiting member 110 on the buffer sleeve 230 and reducing the wear of the buffer sleeve 230, so as to extend the service life of the buffer sleeve 230.
[0054] In some embodiments, see Figure 4The limiting assembly 100 further includes a second mounting plate 130, which is used to be connected to the door body 300. The second mounting plate 130 and the door body 300 can be connected by bolts or snaps; the limiting member 110 is installed on the second mounting plate 130; the second mounting plate 130 is provided with a first waist-shaped through hole 132, which can be connected with a fastener such as a bolt to be used to install the second mounting plate 130 to the door body 300. The plane where the long axis direction of the first waist-shaped through hole 132 is located forms an angle with the extension direction of the limiting member 110, and the angle of the angle is affected by the angle between the door body 300 and another door body 300 (or the load compartment of the traffic equipment) when closed. Due to the different door structure settings of different transportation equipment, when the second mounting plate 130 is installed to the door body 300, the angle formed by the plane where the long axis direction of the first waist-shaped through hole 132 is located and the extension direction of the limit member 110 should be based on the actual situation so that the limit member 110 can be inserted into the limit hole 220; and, when the gap and alignment between a door body 300 and another door body 300 (or a load-bearing compartment of a transportation equipment) need to be adjusted, the position of the second mounting plate 130 connected to the door body 300 is adjusted along the long axis direction of the first waist-shaped hole 132, so as to achieve surface difference control of the transportation equipment.
[0055] In some embodiments, continue to refer to Figure 4 The clamping base 210 is provided with a second waist-shaped through hole 213, which can be connected with a fastener such as a bolt to mount the clamping base 210 to the load compartment of the traffic equipment or another door body 300, and the long axis direction of the second waist-shaped through hole 213 is parallel to the axis direction of the limiting hole 220. That is, the second waist-shaped through hole 213 is parallel to the limiting hole 220 as a whole, so that the position of the first mounting plate 211 connected to the door body 300 can be adjusted along the long axis direction of the second waist-shaped hole, and then the gap and alignment between the door body 300 and another door body 300 (or the load compartment of the traffic equipment) can be adjusted to achieve the surface difference control of the traffic equipment.
[0056] The utility model also provides a traffic device, referring to Figure 7, the transportation equipment can be a car or a van; the transportation equipment includes a lock structure, and the specific structure of the lock structure refers to the above embodiment. As a preferred embodiment, the transportation equipment includes a top door 310 and two side doors 320, the sides of the two side doors 320 are used to abut each other, and the top door 310 is located above the two side doors 320; at least one of the side doors 320 is provided with a clamping base 210 on the top, and at least one stopper 110 is correspondingly provided at the bottom of the top door 310; or, the two side doors 320 are respectively provided with a clamping base 210 on the top, and two stoppers 110 are correspondingly provided at the bottom of the top door 310, and the two stoppers 110 are arranged at intervals. That is, the stopper 110 and the clamping base 210 are respectively provided on the top door 310 and the side door 320, so that the top door 310 is clamped to the side door 320 when closed. The clamping base 210 can be arranged on one side door 320 or on both side doors 320; the number of clamping bases 210 on each side door 320 can be one or more. The number and position of the limiting members 110 correspond to the clamping base 210. In this arrangement, since the swing amplitude of the free end of the top door 310 is small, the matching connection between the limiting hole 220 and the limiting member 110 can provide a stable positioning for the closing of the top door 310, reduce the shaking of the top door 310, and also reduce the risk of the limiting member 110 hitting the limiting hole 220.
