Fig. 1 to 9 show a locking device 100 according to the utility model for locking a component 14 to be locked. The member to be locked 14 is rotatable between a storage position and a supporting position. The locker 100 includes a support member 110, a locking lever 130, an elastic piece 140, and a guide member 120. The support member 110 includes first and second support plates 111 and 112 spaced apart, and a connection plate 113 connecting the first and second support plates 111 and 112. The connection plate 113 is provided with a positioning portion 114. The lock lever 130 is penetrated through the two support plates in the axial direction D, and the lock lever 130 includes a handle 131 protruding in the radial direction of the lock lever 130. The elastic member 140 is sleeved on the lock lever 130, and the elastic member 140 is located between the handle 131 and the second support plate 112 and is used for applying a force to the lock lever 130 towards the first support plate 111. The guide member 120 is connected to the support member 110 and is located between the positioning portion 114 and the first support plate 111. The guide member 120 has a guide surface 121. The first end 121a of the guide surface 121 is adjacent to the positioning portion 114, and the second end 121b of the guide surface 121 corresponds to the lock lever 130. The lock lever 130 is movable in the axial direction D from the locked position to the unlocked position during movement of the handle 131 from the second end 121b along the guide surface 121 toward the first end 121 a.

Compared with the prior art, according to the locking device disclosed by the utility model, the handle is not interfered by the inclined surface connecting part of the container chassis when being operated, the operation space is large, the operation difficulty is reduced, and meanwhile, the handle can be guided to move through the guide surface so as to facilitate the lock rod to move from the locking position to the unlocking position along the axial direction, so that the operation difficulty is further reduced. The locking device disclosed by the utility model has the advantages of simple structure, large operation space when the handle is operated, low operation difficulty and easiness and smoothness in operation.

The directional terms used for the respective components, portions, etc. of the locking device 100 described in the present utility model are with respect to the container 10 in the horizontal and upright state, and the chassis 11 of the container 10 is horizontally disposed. Here, "axial direction" refers to the axial direction D of the lock lever 130, specifically, the axial direction D of the lock pin 132 configured in a cylindrical shape.

Referring to fig. 1 to 9, the first support plate 111 and the second support plate 112 are spaced apart in the axial direction D, and the first support plate 111 and the second support plate 112 are preferably vertical plates substantially perpendicular to the axial direction D, and both ends of the connection plate 113 extend to the first support plate 111 and the second support plate 112, respectively, in the axial direction D, and are formed substantially as support members 110 having U-shaped cross sections. The guide member 120 extends from a side of the positioning portion 114 of the connection plate 113 near the first support plate 111 toward the opening direction of the U-shaped cross section. The guide member 120 has a first end 121a of the guide surface 121 adjacent to the positioning portion 114, and a second end 121b of the guide surface 121 corresponds to the lock lever 130. The positioning portion is closer to the first support plate 111 than the second support plate 112 so that the positioning portion 114 is not too far from the second end 121b of the guide surface 121, avoiding excessive compression of the elastic member 140 or movement of an excessive distance during movement of the lock lever 130 from the locked position to the unlocked position. The positioning portion 114 of the connection plate 113 is configured as an upwardly open notch, for example, a U-shaped opening structure having an upwardly open portion. Thus, the handle 131 slides along the guide surface 121 to be easily received by the positioning portion 114 during movement of the handle 131 from the second end 121b along the guide surface 121 toward the first end 121a, that is, during movement of the lock lever 130 from the locked position to the unlocked position in the axial direction D.

The member to be locked 14 may be provided with a locking notch 15 to allow the member to be locked 14 to receive the locking lever 130 during rotation from the supporting position to the storage position. A portion of the lock lever 130 extends into the locking notch 15 to effect locking of the member to be locked 14.

Alternatively, the first support plate 111 is closer to the member 14 to be locked in the storage position than the second support plate 112, and the second end 121b of the guide surface 121 is closer to the first support plate 111 than the first end 121 a. It is understood that the guide surface 121 has a guide slope provided obliquely with respect to the first support plate 111 and the second support plate 112, along which the handle 131 can be moved more easily and smoothly.

Referring to fig. 1 to 6, the lock lever 130 may further include a lock pin 132, the lock pin 132 being configured to be movably and rotatably penetrated through the first hole portion 115 of the first support plate 111 and the second hole portion 116 of the second support plate 112 in the circumferential direction, the lock pin 132 being radially provided with a mounting hole 134 for fixedly coupling the handle 131. It will be appreciated that the second hole portion 116 of the second support plate 112 may be configured as a through hole or a blind hole, and the first hole portion 115 of the first support plate 111 may be configured as a through hole. The first hole portion 115 and the second hole portion 116 are preferably circular holes coaxially arranged. The locking pin 132 may be generally cylindrically configured with an axial direction D, i.e., the axial direction D of the locking bar 130. The mounting holes 134 may be configured as through holes or as blind holes. The lock pin 132 and the handle 131 may be integrally provided, or may be separately provided and fixedly connected to each other.

The guide member 120 may further have a limiting surface 122, and the limiting surface 122 extends from the second end 121b of the guide surface 121 toward the second support plate 112 to form a limiting portion 123. The stop 123 is provided to receive the handle 131 when the lock lever 130 is in the locked position. At the same time, the stop surface 122 prevents the handle 131 from being turned out and prevents the lock lever 130 from being rotated at will.

Alternatively, the lock lever 130 is provided with an abutment surface 133 at an end near the first support plate 111, the abutment surface 133 of the lock lever 130 having an angle α (see, for example, fig. 5) with the axial direction D, the opening of the angle α being directed toward the second support plate 112, the abutment surface 133 being capable of being pressed during rotation of the member to be locked 14 from the support position to the storage position, so that the member to be locked 14 is capable of applying a force to the lock lever 130 that urges the lock lever 130 to move in the axial direction D from the locking position to the unlocking position. The abutment surface 133 is provided at an end of the lock pin 132 remote from the second support plate 112, and the abutment surface 133 of the lock lever 130 is preferably configured as a slope facing upward, which is configured to face the member to be locked 14 and be in sufficient contact with the member to be locked 14 when the lock lever 130 is in the locked position, in which case the lock pin 132 is most easily moved from the extended state to the retracted state by being pressed.

The angle α of the abutment surface 133 of the lock lever 130 to the axial direction D is preferably greater than or equal to 45 °. In the case where the angle α between the abutment surface 133 configured as the inclined surface and the axial direction D is large, the force applied thereto by the member to be locked 14 can relatively effectively push the lock lever 130 to move from the locking position to the unlocking position in the axial direction D after being decomposed on the inclined surface.

The latch 100 may further include a spacer 150, where the spacer 150 is sleeved on the lock lever 130, specifically, the spacer 150 has a through hole, and the lock lever 130 (specifically, the lock pin 132) is inserted through the through hole. The locking pin 132 is preferably coaxially disposed with the through hole. The gasket 150 is located between the second support plate 112 and the locking bar 130, one side of the gasket 150 in the axial direction directly abuts against the locking bar 130, and the other side of the gasket 150, which is disposed opposite to the one side, is connected to the elastic member 140. The gasket 150 can perform a better fixing function on the elastic member (for example, a compression spring), effectively ensure the usability of the elastic member 140, and bring about a better shock absorbing effect.

The handle 131 may be constructed in an L-shape having a first extension and a second extension, which is ergonomic, easy to handle, and easy to operate. The handle 131 may be made of round steel. The lengths of the first extension portion and the second extension portion are not particularly limited, and can be specifically selected according to actual working conditions.

The process of unlocking the to-be-locked member 14 from the storage position, specifically, the process of unlocking the lock lever 130 from the lock position to the unlock position, that is, the process of moving the handle 131 toward the second support plate 112 and the positioning portion 114, away from the stopper 123, along the guide surface 121 from the second end 121b of the guide surface 121 to the first end 121a of the guide surface 121. At this time, the handle 131 drives the pad 150 to compress the elastic member 140 (e.g., a spring) between the pad 150 and the second support plate 112 to store elastic potential energy.

Fig. 7 to 9 show the locking process of the member to be locked 14 (for example, the top corner member of the end frame 12 of the container 10), and in particular show the active state of the locking device 100 during the rotation of the member to be locked 14 from the supporting position to the storage position. When the lock lever 130 is located at the locking position (i.e., the extended state), the to-be-locked member 14 rotates from the supporting position to the storage position under the action of, for example, gravity, and the to-be-locked member 14 rotates to the abutment surface 133 of the to-be-locked member 130, the abutment surface 133 is preferably an inclined surface, the inclined surface is forced to be disassembled, the lock lever 130 is forced to move from the locking position to the unlocking position (i.e., the retracted state) along the axial direction D until the lowermost edge of the inclined surface abuts against the to-be-locked member 14, the to-be-locked member 14 continues to rotate to the storage position until the locking notch 15 of the to-be-locked member 14 corresponds to the position of the abutment surface 133 of the lock lever 130, and the elastic member 140 sleeved on the lock lever 130 applies a force to the first supporting plate 111 (i.e., releases elastic potential energy stored when the elastic member 140 is compressed), so that the lock lever 130 moves from the unlocking position to the locking position, in other words, the lock lever 130 moves from the retracted position to the extended state, in which the lock pin 132 of the lock lever 130 is specifically, the abutment surface extends into the locking notch 15, thereby realizing locking of the to be-locked. The whole process does not need the operation of staff, and convenient operation uses manpower sparingly.

A second aspect of the utility model provides a container 10. The container 10 comprises a locker 100 according to any of the above described aspects, a chassis 11 and an end frame 12. The support member 110 of the locker 100 is connected to the base frame 11. The end frames 12 are rotatably connected to both ends of the base frame 11, and the top corner pieces of the end frames 12 are pieces to be locked 14. The locking device 100 is used for locking the member to be locked 14 (i.e. the top corner member) in the storage position to the chassis 11, thereby locking the end frame 12 to the chassis 11. The container 10 according to the second aspect of the present utility model can exert technical effects similar to those of the bottom plate 100 of the container 10 of the first aspect described above. It will be appreciated that the container 10 according to the present utility model includes all of the features and effects of the floor 100 of the container 10 according to the present utility model.

The handle 131 preferably does not protrude from the container 10 in the width direction of the container 10. The two ends of the chassis 11 may be provided with hinges such that the end bells 12 are hinged to the two ends of the chassis 11. The member to be locked 14 may be part of the end frame 12, thereby making the construction simple and cost effective.

It will be appreciated that the top corner piece is configured to be rotatable between a stowed position and a support position. When the locking member 14 (i.e., the header) is in the storage position, the locking pin 132 of the locking lever 130 may extend into the top hole of the header to lock the header and thereby lock the end frame 12. When the top corner pieces are all positioned at the storage positions, the folding container is in a folding form. The collapsible container is in an erect configuration when the roof angle members are in the supporting position.

The top corner piece of the end frame 12 serves as the piece to be locked 14, and the top hole of the top corner piece serves as the locking notch 15, and cooperates with the locker 100 to lock the piece to be locked 14 (i.e., the top corner piece) to the bottom frame 11 of the container 10, thereby locking the end frame 12 to the bottom frame 11 of the container 10.
