Description

Technical Field

[0001] This utility model relates to the field of aircraft cargo system technology, specifically to a side guide limit lock. Background Technology

[0002] In containerized air cargo systems, special anti-slip locks are often installed to prevent containers from accidentally sliding out of the aircraft cabin door during loading and unloading.

[0003] Existing anti-slip locking mechanisms typically include a mounting base, a movable limiter, a spindle, and a torsion spring. The movable limiter is rotatably connected to the mounting base via the spindle. The torsion spring is sleeved on the spindle, with one end abutting against the mounting base and the other end abutting against the movable limiter. When the movable limiter is in contact with the mounting base, the side of the movable limiter facing away from the mounting base can support the sliding of the container; when the movable limiter is perpendicular to the mounting base, it can limit the movement of the container.

[0004] However, during container loading, the movable restraints rely entirely on the continuous downward pressure of the container's weight. Once this downward force disappears or decreases, the movable restraints will tend to spring back instantly under the action of the torsion spring, causing the container to move or slide out of the movable restraints. Utility Model Content

[0005] Based on the above description, this utility model provides a side guide limit lock, which aims to solve the problem that the existing anti-slip limit locks have no locking function and will exert force on the container under the action of the torsion spring during container loading, causing the container to move or slide out of the movable limit body.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A side-guided limit lock, comprising: Mounting base; The movable limiter is rotatably connected to the mounting base via a spindle; A locking mechanism includes a limiting member and a stop member. The limiting member is disposed at one end of the spindle, and the stop member is rotatably disposed on the mounting base. The stop member corresponds to the limiting member and has a first position and a second position. When the stop member is in the first position, the stop member is connected to the limiting member. When the stop member is in the second position, the stop member is separated from the limiting member.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the limiting member is a lock sleeve, and the stop member is an unlocking pedal.

[0009] Furthermore, a limiting groove is provided on the lock sleeve, and a limiting part extending toward the lock sleeve is provided on the unlocking pedal.

[0010] Furthermore, the mounting base has a movable hole on the side opposite to the unlocking pedal, and the mounting base has a mounting hole communicating with the movable hole. The axis of the mounting hole is perpendicular to the axis of the movable hole. The unlocking pedal is provided with a pressure rod corresponding to the movable hole. One end of the pressure rod is inserted into the movable hole. The locking mechanism includes a tightening component, which is disposed in the mounting hole. One end of the tightening component abuts against the pressure rod, and the other end of the tightening component is connected to the hole wall of the mounting hole.

[0011] Furthermore, the tightening assembly includes a top post, a first elastic element, and an abutment element arranged sequentially along the axial direction of the mounting hole. The end of the top post facing away from the first elastic element serves as one end of the tightening assembly, and the end of the abutment element facing away from the first elastic element serves as the other end of the tightening assembly.

[0012] Furthermore, it includes at least one second elastic element, which is sleeved on the mandrel, with one end of the at least one second elastic element abutting against the mounting base and the other end of the at least one second elastic element abutting against the movable limiting body.

[0013] Furthermore, it includes a first guide roller, and the mounting base is provided with a first receiving space extending along a first direction. The first guide roller is rotatably disposed within the first receiving space, and the axis of the first guide roller is parallel to the first direction.

[0014] Furthermore, it includes a second guide roller, and the movable limiting body is provided with a second receiving space extending along a second direction. The second guide roller is rotatably disposed in the second receiving space, and the axis of the second guide roller is parallel to the second direction.

[0015] Furthermore, it includes a pressure plate, which is disposed on the movable limiting body, and the pressure plate is disposed opposite to the end of the second guide roller that is away from the mounting base.

[0016] Furthermore, including a roller shaft, the top of the second receiving space is provided with a through hole communicating with the second receiving space, the bottom of the second receiving space is provided with a connecting hole communicating with the second receiving space, the pressure plate is provided with a stepped hole corresponding to the through hole, one end of the roller shaft passes through the stepped hole and the through hole in sequence and is connected to the connecting hole, and the second guide roller is detachably connected to the roller shaft.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: (1) This utility model achieves rapid locking and unlocking of the movable limit body by linking the limiting component and the stop component. Thus, the mounting seat can be selected to guide in a third direction, or the mounting seat and the movable limit body can be coordinated to guide in a third direction and limit in the first direction. This not only improves applicability, but also prevents the container from being subjected to the force of the movable limit body.

[0018] (2) The present invention applies a pushing force to the unlocking pedal by tightening the assembly to ensure that the limiting part and the limiting groove are in cooperation, and prevents the unlocking pedal from rotating downward and causing the limiting part and the limiting groove to separate, thereby further preventing accidental unlocking.

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below" or "below" of the other element or feature will be oriented "above" the other element or feature. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0025] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0026] Reference Figures 1 to 3 As shown, this utility model provides a technical solution: a side-guided limiting lock, including a mounting base 10, a movable limiting body 20, and a locking mechanism 30; the movable limiting body 20 is rotatably connected to the mounting base 10 via a spindle 21; the locking mechanism 30 includes a limiting member 31 and a stop member 32, the limiting member 31 is disposed at one end of the spindle 21, and the stop member 32 is rotatably disposed on the mounting base 10, the stop member 32 corresponds to the limiting member 31, and the stop member 32 has a first position and a second position. When the stop member 32 is in the first position, the stop member 32 is connected to the limiting member 31, and when the stop member 32 is in the second position, the stop member 32 is separated from the limiting member 31.

[0027] It should be noted that the first position refers to the position where the stop 32 is connected to the limit member 31; the second position refers to the position where the stop 32 is separated from the limit member 31.

[0028] According to this embodiment, when the stop 32 is in the first position, the stop 32 is connected to the limiting member 31, restricting the movement of the movable limiting body 20; when the stop 32 is in the second position, the stop 32 is separated from the limiting member 31, and the movable limiting body 20 can rotate freely. The movable limiting body 20 is quickly locked and unlocked by the linkage of the limiting member 31 and the stop 32, thus allowing the mounting base 10 to be guided in the third direction F3, or the mounting base 10 and the movable limiting body 20 to cooperate in guiding in the third direction F3 and limiting in the first direction F1. This not only improves applicability but also prevents the container from being subjected to the force of the movable limiting body 20.

[0029] For example, when the mounting base 10 is selected to guide in the third direction F3, the movable limiting body 20 rotates towards the mounting base 10 with the spindle 21 as the rotation center and is parallel to the mounting base 10. The stop 32 is rotated to the first position, where it connects with the limiting member 31, restricting the movement of the movable limiting body 20. At this time, only the mounting base 10 participates in the guidance. When the mounting base 10 and the movable limiting body 20 cooperate to guide in the third direction F3 and limit in the first direction F1, the stop 32 is rotated to the second position, where it separates from the limiting member 31. Simultaneously, the movable limiting body 20 rotates away from the mounting base 10 with the spindle 21 as the rotation center and is perpendicular to the mounting base 10. At this time, the mounting base 10 participates in the guidance in the third direction F3, and the movable limiting body 20 participates in the limiting in the first direction F1 and the guidance in the third direction F3.

[0030] Reference Figures 1 to 5 As shown, in some embodiments, the limiting member 31 is a locking sleeve 311, and the stop member 32 is an unlocking pedal 321.

[0031] For example, the unlocking pedal 321 is rotatably connected to the mounting base 10 by a screw 3213; that is, the screw 3213 is fixed to the mounting base 10, and the unlocking pedal 321 and the screw 3213 are in clearance fit.

[0032] In this embodiment, the locking sleeve 311 is fixed to the end of the spindle 21, and the unlocking pedal 321 engages and disengages from the locking sleeve 311 by rotation. For example, the unlocking pedal 321 and the locking sleeve 311 are stopped by friction. The unlocking pedal 321 is easy to step on or press by hand, thereby improving operating efficiency.

[0033] In other embodiments, the limiting member 31 can be a gear or the like, and the stop member 32 can be an arc-shaped rack or the like.

[0034] According to this embodiment, the reliability and stability of the locking can be guaranteed.

[0035] Reference Figures 3 to 5 As shown, in some embodiments, a limiting groove 3111 is provided on the lock sleeve 311, and a limiting part 3211 extending toward the lock sleeve 311 is provided on the unlocking pedal 321.

[0036] For example, the limiting part 3211 can be a limiting rod or a protrusion, etc.

[0037] According to this embodiment, when the limiting part 3211 is a limiting rod, the limiting rod can be directly inserted into the limiting groove 3111 to stop the spindle 21. When the limiting part 3211 is a protrusion, the side wall of the limiting groove 3111 abuts against the side wall of the protrusion, so that the protrusion blocks the locking sleeve 311, realizing mechanical interlocking. The cooperation between the limiting part 3211 and the limiting groove 3111 enhances the reliability and stability of locking and prevents accidental unlocking caused by misoperation or vibration.

[0038] Reference Figures 3 to 5 As shown, in some embodiments, the mounting base 10 has a movable hole 12 on the side opposite to the unlocking pedal 321, and the mounting base 10 has a mounting hole 13 communicating with the movable hole 12. The axis of the mounting hole 13 is perpendicular to the axis of the movable hole 12. The unlocking pedal 321 is provided with a pressure rod 3212 corresponding to the movable hole 12. One end of the pressure rod 3212 is inserted into the movable hole 12. The locking mechanism 30 includes a tightening component 33, which is disposed in the mounting hole 13. One end of the tightening component 33 abuts against the pressure rod 3212, and the other end of the tightening component 33 is connected to the hole wall of the mounting hole 13.

[0039] According to this embodiment, when the limiting part 3211 and the limiting groove 3111 cooperate to achieve interlocking, the tightening assembly 33 applies a pushing force to the pressure rod 3212, causing the unlocking pedal 321 to tend to rotate upward. This ensures that the limiting part 3211 and the limiting groove 3111 remain engaged, preventing the unlocking pedal 321 from rotating downward and causing the limiting part 3211 to separate from the limiting groove 3111, further preventing accidental unlocking.

[0040] Reference Figures 3 to 5 As shown, in some embodiments, the clamping assembly 33 includes a top post 331, a first elastic member 332 and an abutment member 333 arranged sequentially along the axial direction of the mounting hole 13. The end of the top post 331 facing away from the first elastic member 332 serves as one end of the clamping assembly 33, and the end of the abutment member 333 facing away from the first elastic member 332 serves as the other end of the clamping assembly 33.

[0041] For example, the first elastic element 332 can be a spring or an elastic rubber pad, etc. The abutment element 333 can be a plug, etc., which is threaded, transition-fitted or interference-fitted to the mounting hole 13.

[0042] According to this embodiment, the first elastic element 332 provides a thrust to the top post 331, and the top post 331 transmits the thrust to the pressure rod 3212, thereby providing a thrust to the unlocking pedal 321.

[0043] Reference Figures 3 to 4 As shown, in some embodiments, the side guide limit lock includes at least one second elastic element 40, which is sleeved on the spindle 21. One end of the at least one second elastic element 40 abuts against the mounting base 10, and the other end of the at least one second elastic element 40 abuts against the movable limit body 20.

[0044] For example, the second elastic element 40 can be a torsion spring, etc.

[0045] According to this embodiment, the second elastic member 40 provides a torsional torque, and after the limiting part 3211 and the limiting groove 3111 are unlocked, the movable limiting body 20 can automatically return to the center.

[0046] Reference Figures 1 to 3 As shown, in some embodiments, the side guide limit lock includes a first guide roller 50, and the mounting base 10 is provided with a first receiving space 11 extending along a first direction F1. The first guide roller 50 is rotatably disposed in the first receiving space 11, and the axis of the first guide roller 50 is parallel to the first direction F1.

[0047] According to this embodiment, the first guide roller 50 is used to guide the container to slide along a third direction F3. During the sliding process of the container, the first guide roller 50 can reduce friction and improve the smoothness of movement and guiding accuracy.

[0048] Reference Figures 1 to 3 As shown, in some embodiments, the side guide limit lock includes a second guide roller 60, and the movable limit body 20 is provided with a second receiving space 22 extending along the second direction F2. The second guide roller 60 is rotatably disposed in the second receiving space 22, and the axis of the second guide roller 60 is parallel to the second direction F2.

[0049] In this embodiment, the second guide roller 60 contacts the side of the container, which can both restrict the movement of the container along the first direction F1 and guide the container to slide along the third direction F3. During the sliding process of the container, the second guide roller 60 can reduce friction and prevent the container from sliding sideways.

[0050] Reference Figures 1 to 3 As shown, in some embodiments, the side guide limit lock includes a pressure plate 70, which is disposed on the movable limit body 20, and the pressure plate 70 and the end of the second guide roller 60 opposite to the mounting base 10 are disposed opposite to each other.

[0051] According to this embodiment, when the container has a flange, the pressure plate 70 limits the flange in the second direction F2 to prevent vibration and other factors from causing the container to disengage from the side guide limit lock.

[0052] Reference Figures 1 to 3 and Figures 6 to 7 As shown, in some embodiments, the side guide limit lock includes a roller shaft 80, a through hole 221 communicating with the second receiving space 22 is provided at the top of the second receiving space 22, a connecting hole 222 communicating with the bottom of the second receiving space 22, a stepped hole is provided on the pressure plate 70 corresponding to the through hole 221, one end of the roller shaft 80 passes through the stepped hole and the through hole 221 in sequence and is connected to the connecting hole 222, and the second guide roller 60 is detachably connected to the roller shaft 80.

[0053] For example, the roller shaft 80 is threaded or transitionally fitted with the connecting hole 222.

[0054] According to this embodiment, the pressure plate 70 or the second guide roller is so easy to disassemble and assemble, making it convenient to replace the worn pressure plate 70 or the second guide roller.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
