[0056] Reference will now be made to Figures 1 to 8 Example embodiments according to the present disclosure will be described in more detail. A first aspect of the present disclosure provides a chassis 100 arranged in a container 10.
[0057] With reference to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the chassis 100 is provided with a slot 114, the slot 114 has a receiving cavity 115 and a socket 116, the receiving cavity 115 is in communication with the outside through the socket 116, and the bottom edge of the socket 116 is spaced apart from the bottom of the chassis 100 by a predetermined distance in the vertical direction D1. The chassis 100 further comprises a pedal device 120, which is telescopically arranged in the receiving cavity 115. The pedal device 120 has an outer end 123 and an inner end 124, when the pedal device 120 extends out of the socket 116 and the outer end 123 touches the ground, the height of the outer end 123 is lower than the height of the inner end 124, so as to form a slope with the pedal device 120. The inner end 124 of the pedal device 120 is connected with a first limiting piece 125, the first limiting piece 125 is used to limit the inner end 124 of the pedal device 120 to extend out of the socket 116.
[0058] According to the chassis 100 of the present application, a ramp for stepping on is provided when a worker needs to enter the container 10, and the pedal device 120 is allowed to be pulled out to form the ramp when in use, and hidden in the chassis 100 when not in use, and the pedal device 120 is formed as part of the chassis 100, without affecting the normal use and structural safety of the container 10, while improving the operation experience of the worker and improving the work efficiency.
[0059] The chassis 100 comprises a bottom side beam 110, a bottom cross beam 140, and a floor 160, a plurality of bottom cross beams 140 are arranged at intervals between two bottom side beams 110, and the floor 160 is arranged above the bottom cross beams 140. Preferably, the socket 116 is opened on the bottom side beam 110. And the extension direction of the pedal device 120 is preferably consistent with the extension direction of the bottom cross beam 140. As an implementation form, the slot 114 is arranged between two adjacent bottom cross beams 140. And the slot 114 can further comprise a bottom cover plate 118 and a rear cover plate 119, the bottom cover plate 118 is arranged at intervals on the lower side of the floor 160, and the rear cover plate 119 is connected between two adjacent bottom cross beams 140, wherein the floor 160, the bottom cover plate 118, the rear cover plate 119 and the two adjacent bottom cross beams 140 substantially form the above-mentioned accommodating cavity 115.
[0060] Preferably, in order to make the worker pull the pedal device 120 more smoothly, the slot 114 is further provided with a guide assembly 150. The guide assembly 150 comprises a guide rail and a moving piece, the guide rail is connected to the bottom cross beam 140, and the extension direction of the guide rail is consistent with the extension direction of the bottom cross beam 140. The moving piece is movably arranged in the guide rail, and the pedal device 120 is connected with the moving piece.
[0061] It can be understood that when the container 10 is in a normal use state, the bottom cross beam 140 extends horizontally or substantially horizontally; thus, in the present embodiment, the slot 114 also extends horizontally or substantially horizontally, and the pedal device 120 extends horizontally or substantially horizontally.
[0062] In other optional embodiments, under the premise of ensuring that the pedal device 120 can be extended and retracted in the slot 114 and can be extended out of the socket 116, the slot 114 can also be selected to be arranged to extend downwardly or in other directions.
[0063] Reference Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7The first limiting member 125 extends beyond the bottom surface and / or the top surface of the inner end 124 of the pedal device 120 in the vertical direction D1, and the overall height of the first limiting member 125 and the inner end 124 of the pedal device 120 in the vertical direction D1 is greater than the height of the socket 116. When the pedal device 120 is extended to the limit position in the socket 116, the first limiting member 125 abuts against the wall surface on the side of the bottom side beam 110 facing the accommodating cavity 115.
[0064] In the embodiment, the first limiting member 125 is a first pad arranged below the inner end 124. In other alternative embodiments, the first limiting member 125 can also be a limiting block protruding above the inner end 124. Alternatively, the first limiting member 125 can also be a limiting block protruding on both vertical sides and / or both lateral sides of the inner end 124. It should be noted that the first limiting member 125 can also be arranged in other structures capable of abutting against the wall surface on the side of the bottom side beam 110 facing the accommodating cavity 115. In addition, the first limiting member 125 can also be clamped in a certain clamping groove to limit the pedal by clamping, and does not necessarily have to be arranged in the shape of a pad.
[0065] It can be understood that the first limiting member 125 limits the limit position of the pedal device 120 extended out of the socket 116. In actual use, the pedal device 120 can select a suitable extension length according to needs, and does not necessarily have to be extended to the limit position.
[0066] The outer end 123 of the pedal device 120 can also be provided with a second limiting member 126 to limit the pedal device 120 when it is retracted into the socket 114, so as to prevent the pedal device 120 from being completely immersed in the socket 114 and thus being unable to be taken out by the staff.
[0067] As an implementation form, the second limiting member 126 extends beyond the bottom surface and / or the top surface of the outer end 123 of the pedal device 120 in the vertical direction D1, and the overall height of the second limiting member 126 and the outer end 123 of the pedal device 120 in the vertical direction D1 is greater than the height of the socket 116. When the pedal device 120 is retracted to the limit position in the socket 116, the second limiting member 126 abuts against the wall surface on the side of the bottom side beam 110 away from the accommodating cavity 115.
[0068] In the embodiment, the second limiting member 126 is a second pad arranged below the outer end 123, thereby simultaneously achieving limiting in the retraction direction and supporting the pedal device 120 on the ground. In order not to affect the formation of the slope of the pedal device 120, the height dimension of the second limiting member 126 is less than the height dimension between the bottom edge of the socket 116 and the bottom of the bottom frame 100.
[0069] In other alternative embodiments, the second limiting member 126 can also be a limiting block protruding above the outer end 123. Alternatively, the second limiting member 126 can also be a limiting block protruding on both vertical sides and / or both lateral sides of the outer end 123. It should be noted that the second limiting member 126 can also be configured as other structures capable of abutting against the wall surface of the side of the bottom side beam 110 opposite to the accommodating cavity 115. In addition, the second limiting member 126 can also be in the form of being clamped in a certain clamping groove to limit the pedal, and does not necessarily have to be configured in the shape of a pad.
[0070] The pedal device 120 can be more specifically configured as Figure 6 , and 7 and Figure 8 , which comprises a frame structure 121 and a foot pedal 122 arranged on the top surface of the frame structure 121. The first limiting member 125 and the second limiting member 126 are arranged on the bottom surface of the frame structure 121. Among them, the foot pedal 122 is preferably configured as a mesh.
[0071] In the present embodiment, as Figures 1 to 4 indicated, the bottom side beam 110 is a rectangular beam. In the extension direction of the pedal device 120, the rectangular beam comprises an inner side wall 112 close to the accommodating cavity 115 and an outer side wall 111 close to the outside. Among them, the outer side wall 111 is provided with a working opening 113, and the inner side wall 112 is provided with a socket 116. In the extension direction of the pedal device 120, the projection of the socket 116 completely falls into the projection of the working opening 113.
[0072] By setting the opening area of the working opening 113 to be larger than the opening area of the socket 116, the inner side wall 112 of the bottom side beam 110 can be more fully exposed, which facilitates the worker to perform the operation of pulling out the pedal device 120 through the socket 116.
[0073] Preferably, referring to Figure 3 and Figure 4 , the base frame 100 further comprises a reinforcing member 117 connected between the edge of the working opening 113 and the inner side wall 112.
[0074] In an embodiment not shown, the bottom side beam can also be configured as a C-shaped beam, and the opening of the C-shaped beam is the above-mentioned working opening.
[0075] In order to prevent the pedal device 120 from being automatically extended due to transportation and other factors after being retracted, the base frame 100 further comprises a locking device 130. The locking device 130 comprises a locking structure 131 and a cooperating structure 132, and when the pedal device 120 is retracted into the socket 116 to the limit position, the locking structure 131 can be connected with the cooperating structure 132 to form a lock.
[0076] As an implementation form, one of the locking structure 131 and the cooperating structure 132 is arranged on the bottom side beam 110, and the other is arranged on the pedal device 120. More specifically, the outer end 123 of the pedal device 120 is arranged with the locking structure 131 on one of the wall surfaces of the bottom side beam 110 away from the accommodating cavity 115, and the other is arranged with the cooperating structure 132.
[0077] With reference to Figure 1 , Figure 2 and Figure 8 , in order to achieve that the pedal device 120 can be substantially flush with the inner side wall 112 of the bottom side beam 110 when the pedal device 120 is retracted into the socket 116 to the limit position, it is preferred that the locking structure 131 is arranged on the inner side wall 112 away from the accommodating cavity 115, and the cooperating structure 132 is arranged on the outer end 123 of the pedal device 120. It is worth mentioning that the above-mentioned arrangement of the opening area of the work opening 113 being larger than the opening area of the socket 116 is also more suitable for the arrangement of the locking device 130.
[0078] In the embodiment, the locking structure 131 can be configured as a lock rod, a lock seat structure, for example, a spring bolt and a matching structure. Correspondingly, the cooperating structure 132 can be configured as a lock hole matched with the lock rod or the bolt. In other alternative embodiments, the locking structure 131 can also be a bolt body, and the cooperating structure 132 can also be a bolt seat, both forming a bolt structure. The bolt body can be in the form of sliding or rotating.
[0079] In addition, in an embodiment not shown, the locking structure 131 and the cooperating structure 132 can be arranged on the bottom side beam 110. For example, the locking structure 131 can be configured as a blocking door pivotally connected with the bottom side beam 110, and the blocking door is provided with a locking member such as a lock rod, a lock tongue, etc., and the cooperating structure 132 can be matched with the lock rod, the lock tongue, etc. When it is needed to lock the pedal device 120, the blocking door is pivoted to block the socket 116, and the locking member is connected with the cooperating structure 132.
[0080] The second aspect of the application provides a container 10, which comprises the chassis 100 of the above-mentioned first aspect. Moreover, the container 10 is further provided with a container door 11, and the socket 116 is vertically below the container door 11.
[0081] According to the container 10 of the application, the pedal device 120 below the container door 11 can facilitate the staff to enter and exit the container door 11, which has similar technical effects to the chassis 100 of the above-mentioned first aspect.
