Description

Technical Field

[0001] The utility model relates to the technical field of truck compartments, in particular to a central column inclined outward expansion structure. Background Art

[0002] The center column of the existing truck compartment is generally fixed to the side beam by plugging and unplugging. The specific structure is: a plug-in slot is provided on the side beam, and a plug pin that cooperates with the plug-in slot is provided on the bottom surface of the center column. The plug pin is inserted into the plug-in slot to achieve the installation of the center column. However, the existing plug-in slot is generally matched with the plug pin by sticking to the wall, which makes the center column unable to tilt. The compartment baffle needs to be fixed on the center column, so that the width of the entire compartment remains unchanged. During the loading process, some goods meet the width requirements of the compartment, but because of slight deformation of the baffle or slight protrusions on the goods, when the goods enter from the rear of the compartment, it causes interference with the compartment baffle or the center column, causing the goods to be unable to pass smoothly into the compartment. Utility Model Content

[0003] The utility model aims to provide a central column inclined outward expansion structure, by reasonably setting the width of the pin and the insertion warehouse, so that the pin can be tilted in the insertion warehouse, so that the central column forms an outward inclination angle, thereby facilitating the loading and unloading of goods.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a central column inclined outward expansion structure, comprising a plug-in pocket arranged on a side beam and a plug-in pin arranged at the bottom of the central column and inserted into the plug-in pocket; the plug-in pocket is a slot body structure arranged on the side beam, a slot is arranged at the top of the slot, the width of the slot is smaller than the width of the plug-in pocket and larger than the width of the plug-in pin; after the plug-in pin is inserted into the plug-in pocket, the bottom of the plug-in pin does not contact the bottom of the plug-in pocket, and the bottom surface of the central column abuts against the slot.

[0005] After adopting the above structure, by designing the width of the slot on the top of the insertion pocket to be smaller than the width of the insertion pocket and larger than the width of the pin, when the pin is inserted from the slot, it can be tilted at a certain angle with one side of the slot as a fulcrum. At this time, the width of the insertion pocket is larger than the width of the slot, so that no interference will be caused. When tilted to a certain angle, the side of the insertion pocket or the side wall of the slot limits the pin so that it will not fall. The neutral column forms a certain outward inclination angle, which is convenient for a certain avoidance of goods and ensures the smooth passage of goods.

[0006] In order to limit the center column to only tilt outward, a notch is provided on the top of the insertion pocket on one side close to the outer side of the carriage.

[0007] In order to limit the bottom of the pin and avoid deformation of the notch caused by limiting the notch only, when the pin is tilted to the maximum angle, the bottom of the pin abuts against the side wall of the insertion library.

[0008] In order to achieve the purpose of lightweight carriage, reduce the weight of the center column and ensure the strength of the pin, the pin includes a U-shaped plate fixed to the bottom of the center column, a support plate is arranged inside the U-shaped groove of the U-shaped plate, and both sides of the support plate are respectively fixed to the groove wall of the U-shaped groove.

[0009] In order to avoid water accumulation in the plug reservoir, leakage holes are provided on both sides of the bottom of the plug reservoir.

[0010] In order to prevent excessive pressure from the center column on the plug-in compartment due to an excessively large inclination angle, causing deformation or damage to the plug-in compartment, the outward inclination angle of the center column is 8 to 13 degrees.

[0011] In order to achieve the goal of lightweight carriage and ensure the fixing stability of the center column and the pin, a mounting cavity is provided on the bottom surface of the center column, the top of the pin is inserted and fixed in the mounting cavity, and the bottom of the pin extends out of the mounting cavity and is inserted into the socket.

[0012] In order to increase the contact area between the bottom of the center pillar and the slot, and at the same time reduce the length of the contact line between the bottom of the pillar and the slot when tilting outward to avoid increasing the difficulty of tilting, the center pillar is an "I"-shaped structure with protruding wing panels on both sides located on the inner side of the car.

[0013] After adopting the above technical solution, the beneficial effects of the utility model are:

[0014] The utility model discloses a center column inclined outward expansion structure to solve the technical problem in the prior art that the center column cannot be inclined, resulting in that goods that meet the width requirements cannot be loaded due to slight deformation or interference caused by some protrusions. The utility model reasonably sets the width of the plug pins and the plug-in warehouse, so that the plug pins can be tilted outward in the plug-in warehouse, so that the center column forms an outward inclination angle, which facilitates the loading and unloading of goods.

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] The orientations mentioned in this specification are based on the orientations of the inclined outward expansion structure of the central column of the utility model when it is working normally, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0024] like Figure 1 and Figure 2 As shown together, a center column inclined outward expansion structure includes an insertion pocket 11 arranged on a side beam 1 and a pin 21 arranged at the bottom of the center column 2 and inserted into the insertion pocket 11 .

[0025] like Figure 2 , Figure 3 and Figure 4 As shown together, the plug-in pocket 11 is a slot structure arranged on the side beam 1, and a slot 111 is arranged on the top thereof. The pin 21 is inserted into the plug-in pocket 1 from the slot 111. When the pin 21 is inserted into the plug-in pocket 11, the bottom of the pin 21 does not contact the bottom of the plug-in pocket 11, and the bottom of the center column 2 rests on the top of the slot 111, thereby realizing the vertical limitation of the center column 2.

[0026] like Figure 4 and Figure 5 As shown in the figure, the width of the slot 111 is smaller than the width of the insertion pocket 11 and larger than the width of the pin 21; therefore, when the pin 21 is inserted into the insertion pocket 11 from the slot 111, there is a certain gap between the pin 21 and the periphery of the slot 111, so that it is easy to tilt; because the width of the slot 111 is smaller than the width of the insertion pocket 11, when the pin 21 is tilted, the periphery of the insertion pocket 11 does not interfere with the pin 21, and when tilted to the maximum angle, the pin 21 can be restricted by the side wall of the slot 111 or the side limit of the insertion pocket 11, so that the center column 2 is prevented from falling and the goods are convenient to pass. The top of the center column 2 is generally tightened by the center column 2 on both sides through the cross tie rod, so there will be no problem of tilting and shaking of the center column 2 during normal driving.

[0027] like Figure 5As shown, in this embodiment, when the plug pin 21 is tilted to the maximum angle, the bottom of the plug pin 21 abuts against the side wall of the insertion pocket 11. Due to the lever effect, if the side wall of the slot 111 is used for restriction, the required reaction force is large, so a large force will be generated on the slot 111, causing the slot 111 to deform. However, through the restriction of the side wall of the insertion pocket 11, the force of the plug pin 21 on the slot 111 can be reduced, preventing the inner side of the slot 111 from being deformed by excessive force.

[0028] like Figure 4 and Figure 5 As shown in the figure, in order to prevent excessive pressure of the center column 2 on the insertion pocket 11 due to an excessively large inclination angle, thereby causing deformation or damage to the insertion pocket 11, the outward inclination angle of the center column 2 is 8 to 13°. In this embodiment, the outward inclination angle of the column 2 is 13°.

[0029] In order to limit the tilting direction of the center pillar 2, the notch 111 is set on the side of the top of the insertion pocket 11 close to the outside of the car, so that when the center pillar 2 is not tilted, the outer side of the pin 21 abuts against the side wall of the insertion pocket 11, thereby preventing the pin 21 from tilting toward the inside of the car.

[0030] In order to prevent water from accumulating in the insert reservoir 11 , leakage holes 112 are provided on both sides of the bottom of the insert reservoir 11 .

[0031] like Figure 2 and Figure 6 As shown together, in order to achieve the purpose of light weight and to ensure the strength of the plug pin 21, the plug pin 21 includes a U-shaped plate 211 fixed to the bottom of the center column 2, and a support plate 212 is arranged inside the U-shaped groove of the U-shaped plate 211, and both sides of the support plate 212 are respectively fixed to the groove wall of the U-shaped groove. The U-shaped plate 211 is reinforced by the support plate 212, thereby improving the strength of the plug pin 21.

[0032] like Figure 2 As shown, in order to ensure the purpose of lightweight carriage and ensure the fixing stability of the center column 2 and the pin 21, a mounting cavity is provided at the bottom of the center column 2, and the top of the pin 21 is inserted and fixed in the mounting cavity. This embodiment adopts a welding method, in which the top of the pin 21 is welded in the mounting cavity, and the bottom of the pin 21 extends out of the mounting cavity and is inserted into the plug-in magazine 11.

[0033] In order to increase the contact area between the bottom of the center pillar 2 and the notch 111, the center pillar 2 is an "X"-shaped structure, with the protruding wing panels on both sides located on the inner side of the vehicle compartment, thereby increasing the contact area without reducing the difficulty of tilting outwards.

[0034] The utility model discloses a center column inclined outward expansion structure to solve the technical problem in the prior art that the center column cannot be inclined, resulting in that goods that meet the width requirements cannot be loaded due to slight deformation or interference caused by some protrusions. The utility model reasonably sets the width of the plug pins and the plug-in warehouse, so that the plug pins can be tilted outward in the plug-in warehouse, so that the center column forms an outward inclination angle, which facilitates the loading and unloading of goods.

[0035] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
