[0002] Containers are a type of grouped tool that can carry packaged or unpackaged goods for transportation and is convenient for loading and unloading with mechanical equipment. Therefore, the goods transported are also diverse. When transporting some fresh food, refrigeration is required in the container, so some refrigeration equipment needs to be installed in the container. When installing these refrigeration equipment in the container, it is necessary to first install a battery rack in the container, and then install several batteries in the container to provide power for the refrigeration equipment.

[0003] In the process of installing the battery rack in the container, the key factor to consider is that the container has been made. Therefore, if the battery rack is to be fixed inside the container, it is inevitable to use welding or punching holes and bolts to fix the battery rack to the inner wall of the container. This method will make the process of installing and removing the battery rack from the container more cumbersome. Since the container is a container, there are many kinds of materials transported, not all of which need refrigeration; when the items in the container do not need refrigeration, removing the battery rack can increase the space inside the container; therefore, the installation and removal of the battery rack from the container has become more frequent, so it is necessary to design a battery rack that is easy to install and remove to match the container.

DETAILED DESCRIPTION

[0041] like Figure 1-15As shown, a battery rack for use in a container comprises a battery rack body 1, the cross section of the battery rack body 1 is rectangular, a battery insertion port is arranged on one side wall of the battery rack body 1, a contact plate is arranged on the outer side wall of the battery rack body 1 adjacent to the battery insertion port via a telescopic device, a plurality of push rods 2 facing away from the battery rack body 1 are arranged on the contact plate via elastic members, the push rods 2 are perpendicular to the outer side wall of the battery rack body 1 where the telescopic device is arranged, and a lock for fixing the push rods 2 is arranged on the contact plate.

[0042] Since there are many longitudinal grooves 43 on the inner side wall of the container 44 after the container 44 is manufactured, the contact plate is provided with a push rod 2 in the present application. That is, when in use, the battery rack body 1 is first placed against an inner side wall (assuming the left side wall) of the container 44 on the side facing away from the contact plate, and then the contact plate is moved toward the other opposite side wall (assuming the right side wall) of the container 44 through the telescopic device, so that the end of the push rod 2 away from the contact plate contacts the inner side wall (assuming the right side wall) of the container 44 facing away from the battery rack body 1, and then the telescopic device is continued to be extended until the push rod 2 is squeezed by the inner side wall of the container 44 so that the elastic member contracts, and then the locker locks the push rod 2 relative to the contact plate. Since a plurality of push rods 2 are provided, the push rod 2 contacts the grooves on the container 44 to increase the friction force, and then the required battery can be installed on the battery rack body 1. Of course, contact plates can also be provided on both opposite outer side walls of the battery rack body 1 through the telescopic device, which has a better effect. After such arrangement, if there is no need to install batteries in the container 44 , the battery rack body 1 can be removed from the container 44 by simply retracting the telescopic device, thereby increasing the space inside the container 44 .

[0043] As a preferred method, Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the contact plate includes a base plate 3 and an auxiliary plate 4. The base plate 3 is fixedly connected to one end of the telescopic device facing away from the battery rack body 1. The base plate 3 is parallel to the side wall of the telescopic device arranged on the battery rack body 1. The auxiliary plate 4 is arranged on the side of the base plate 3 facing away from the battery rack body 1 through a support column 5. The auxiliary plate 4 is parallel to the base plate 3. A plurality of first through holes 6 are arranged on the auxiliary plate 4. The axes of the first through holes 6 are perpendicular to the side wall of the telescopic device arranged on the battery rack body 1. The two ends of the push rod 2 are slidably connected to the first through holes 6. The end of the push rod 2 facing the base plate 3 is fixedly connected to the base plate 3 through the elastic member.

[0044] After this arrangement, when the base plate moves toward the inner wall of the container 44 driven by the telescopic device, the push rod 2 is squeezed by the inner wall of the container 44 to cause the elastic member to contract. The support column 5 exists to allow space between the auxiliary plate 4 and the base plate 3 to allow the elastic member to contract.

[0045] As a preferred embodiment, the elastic member is a spring 7 , and the spring 7 is coaxial with the support rod 2 .

[0046] As a preferred method, Figure 3 , Figure 7 As shown, the lock includes a first clamping plate 8, a second clamping plate 9, and a driving member. The first clamping plate 8 and the second clamping plate 9 cooperate with each other. The first clamping plate 8 and the second clamping plate 9 are both slidably arranged on the auxiliary plate 4 facing the side of the substrate 3. The first clamping plate 8 and the second clamping plate 9 are respectively arranged on the opposite sides of each of the push rods 2. The driving member drives the first clamping plate 8 and the second clamping plate 9 to slide relative to each other. After the push rod 2 is squeezed and moved to the direction of the substrate 3 to a preset displacement, the first clamping plate 8 is driven by the driving member to move closer to the second clamping plate 9, so that the first clamping plate 8 and the second clamping plate 9 clamp the push rod 2 together. When the push rod 2 does not need to be clamped, the first clamping plate 8 is moved back to the second clamping plate 9 or the second clamping plate 9 is moved back to the first clamping plate 8 or the first clamping plate 8 and the second clamping plate 9 are moved back to each other by the driving member, so that the clamping of the push rod 2 is released.

[0047] As a preferred mode, a plurality of the first through holes 6 are provided in a matrix on the auxiliary plate, and a first clamping plate 8 and a second clamping plate 9 are slidably provided on opposite sides of each column of the first through holes 6 on the auxiliary plate 4. After such arrangement, the first clamping plates 8 and the second clamping plates 9 that cooperate with each other can simultaneously clamp a column of push rods 2 after being brought close to each other, and the first clamping plates 8 and the second clamping plates 9 that cooperate with each other can simultaneously release the clamping restrictions of a column of push rods 2 after being moved away from each other. This facilitates manufacturing and control. Compared with making a pair of first clamping plates 8 and second clamping plates 9 that cooperate with each other for each push rod 2, it mainly reduces the manufacturing difficulty and manufacturing cost.

[0048] As a preferred embodiment, the driving member includes a second worm 10, a second worm wheel 11, a first rack 12, a first mounting plate 13, a first wedge block 14, a first fixed plate 15, and a second limiter.

The first rack 12 is slidably arranged on a side of the auxiliary plate 4 facing the base plate 3. The part of the second worm wheel 11 facing the base plate 3 cooperates with the second worm 10, and the second worm 10 is rotatably arranged on the base plate 3 through the first fixed plate 15 On the upper side, one end of the second worm gear 10 faces the side of the battery rack body 1 where the battery insertion port is set, and the other end faces away from the side of the battery rack body 1 where the battery insertion port is set. The part of the second worm gear 11 facing the auxiliary plate 4 is meshed with the first rack 12, and the sliding direction of the first rack 12 is the length direction of the first rack 12. The end of the first rack 12 away from the second worm gear 11 is fixedly connected to the first mounting plate 13 above the auxiliary plate 4. A plurality of first wedge blocks 14 are fixedly set on the surface of the first mounting plate 13 facing the second worm gear 11. Driven by the first rack 12, each of the first wedge blocks 14 can enter between two adjacent and non-mutually matching first clamping plates 8 and second clamping plates 9 corresponding to each other.

[0049] After such arrangement, the user rotates the second worm 10, thereby causing the second worm wheel 11 to rotate, and the gear teeth on the second worm wheel 11 also mesh with the first rack 12. Figure 7 As shown, the second rack 12 will move under the action of the second worm gear 11, thereby driving the first mounting plate 13 and the first wedge block 14 located on the first mounting plate 13 to move. Figure 7 For example, if the first wedge block 14 moves downward, the first wedge block 14 will be inserted between two adjacent and non-mutually matched first clamping plates 8 and second clamping plates 9, so that the two mutually matched first clamping plates 8 and second clamping plates 9 are brought closer to each other to clamp the abutment rod 2; and when the first wedge block 14 moves upward, the clamping of the mutually matched first clamping plates 8 and second clamping plates 9 on the abutment rod 2 is released.

[0050] As a preferred mode, the driving member further comprises a second rack 16, a second mounting plate 17, and a second wedge block 18. The second rack 16 is slidably arranged on the side of the auxiliary plate 4 facing the base plate 3. The sliding direction of the second rack 16 is the length direction of the second rack 16. The upper end of the second rack 16 is meshed with the second worm gear 11. The lower end of the second rack 16 is fixedly connected to the second mounting plate 17 at the lower end of the auxiliary plate 4. A plurality of second wedge blocks 18 are fixedly arranged on the side of the second mounting plate 17 facing the second worm gear 11. Each second wedge block 18, driven by the second rack 16, can enter between the two adjacent and non-cooperating first clamping plates 8 and second clamping plates 9. After such arrangement, the first wedge block 14 and the second wedge block 18 move together, so that the first clamping plate 8 and the second clamping plate 9 are subjected to uniform force in the process of being driven to approach each other.

[0051] As a preferred embodiment, the auxiliary plate is provided with two first racks 12, two second racks 16, and two second worm gears 11, the two second worm gears 11 cooperate with the same second worm 10, the two second worm gears 11 are both arranged on the auxiliary plate 4, all the first through holes 6 are located between the two second worm gears 11, one first rack 12 and one second rack 16 cooperate with one second worm gear 11, the mutually cooperating first rack 12 and second rack 16 are separated on the opposite sides of the corresponding second worm gear 11, and the first rack 12 and the second rack 16 are parallel to each other; when facing the side of the auxiliary plate 4 facing the base plate 3, the mutually cooperating first racks 12 are both located on the right side of the second rack 16 or the mutually cooperating first racks 12 are both located on the left side of the second rack 16. After such arrangement, the same second worm 10 can drive the two second worm gears 11 at the same time, and when the second worm gears 11 rotate in the same direction, the two first racks 12 move in the same direction, and the two second racks 16 move in the same direction. This is relatively simple and convenient, and at the same time, the first mounting plate 13 and the second mounting plate 17 are subjected to uniform force during the process of being driven to move.

[0052] As a preferred embodiment, the second stopper comprises a second rotating disk 19, a second bolt 20, and a second handle 21.

The battery rack body 1 is provided with a first stopper, and the first stopper is used to limit the rotation of the first worm 25 after the first worm 25 rotates to a preset position. After such a setting, the rotation of the first worm 25 causes the first worm wheel 26 to rotate, and the rotation of the first worm wheel 26 drives the screw to move axially in the second through hole 28, thereby playing a contraction role.
