Description

Technical Field

[0001] This application relates to the field of battery casings, and more particularly to a battery casing with a leak-proof function. Background Technology

[0002] Battery casings are typically made of materials with a certain strength and toughness, such as flame-retardant ABS. These materials improve the battery's mechanical strength and prevent damage from external impacts and compression during use. The casing covers the positive and negative terminals of the battery, preventing them from being directly exposed and thus avoiding physical damage such as impacts and scratches, ensuring the battery's normal operation.

[0003] However, during the use of battery plastic casings, because the battery contains electrolyte, which is corrosive and toxic, if the sealant between the battery plastic casing and the top cover is not applied evenly or the sealant is aged, the sealing performance of the battery plastic casing may be poor, which may easily lead to electrolyte leakage. Utility Model Content

[0004] In order to seal the inside of the housing and quickly install the cover onto the housing, this application provides a battery plastic housing with anti-leakage function.

[0005] This application provides a battery casing with anti-leakage function, which adopts the following technical solution:

[0006] A battery casing with anti-leakage function includes a housing, a lifting rod slidably mounted on the housing, a casing cover snapped onto the housing, a limiting mechanism fixed on the casing cover, and a sealing mechanism fixed on the housing and casing cover. The sealing mechanism includes a retaining frame and a limiting block. The retaining frame is fixedly connected to the casing cover, and the limiting block is fixedly mounted on the retaining frame. A fixing frame is fixedly connected to the housing, and the fixing frame has a groove. The retaining frame and the fixing frame are snapped together.

[0007] By adopting the above technical solution, when the cover moves the frame to engage with the fixed frame installed on the housing, the limiting block can be positioned in the groove, thereby sealing the top of the housing with the cover.

[0008] Optionally, the sealing mechanism further includes partitions and storage slots. Several partitions are fixedly installed at equal intervals on the housing, and a storage slot is provided between two adjacent partitions.

[0009] By adopting the above technical solution, the partition design makes it easier for operators to place multiple batteries into the storage slot in sequence, and then to place the batteries into the casing.

[0010] Optionally, a limiting block is fitted into the groove, and the portion of the limiting block that contacts the fixing frame has an inclined structure.

[0011] By adopting the above technical solution, when the limiting block is in the groove, the fixed frame can limit the limiting block, thereby causing the card frame to engage with the fixed frame.

[0012] Optionally, the two lifting rods are symmetrically installed on both sides of the housing, and the bottom end of the lifting rods is arranged in an L-shape.

[0013] By adopting the above technical solution, when it is necessary to move the battery casing, the lifting rod can be pulled upwards, thereby allowing the lifting rod to slide inside the casing, which facilitates the movement of the casing.

[0014] Optionally, the limiting mechanism includes a locking block and a slot. The locking block is fixedly connected to the cover, and the slot is provided inside the locking block. A protrusion is fixedly connected to the housing, and a locking rod is fixedly installed on the protrusion. The locking block and the protrusion are engaged and connected. A fixing block is threadedly connected to the locking rod.

[0015] By adopting the above technical solution, when the cover is snapped onto the housing, the snap-fit ​​block can be snapped onto the protrusion, and the snap-fit ​​block can be fixed onto the protrusion by the fixing block.

[0016] Optionally, the protrusion is arranged in a cuboid structure, and the width of the protrusion is greater than the diameter of the latch rod.

[0017] By adopting the above technical solution, the protrusion and the locking block are engaged and connected, which can limit the locking block and thus limit the cover.

[0018] Optionally, the top of the fixing block abuts against the top of the card block, and the fixing block is configured in the form of a regular hexagon.

[0019] By adopting the above technical solution, when the fixing block is threaded onto the side wall of the clamping rod, the fixing block can limit the clamping block.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. When sealing the top of the housing, the operator can snap the fixed frame on the housing cover onto the fixed frame installed on the top of the housing. Since the fixed frame has several grooves, when installing the frame, the fixed limiting block on the frame can be aligned with the groove, so that the limiting block can snap into the inside of the fixed frame. Since the part of the fixed frame that contacts the limiting block is set with a beveled structure, the fixed frame limits the limiting block, which can quickly install the housing cover.

[0022] 2. Since the fixing frame is located at the top of the housing, when the clip frame and the fixing frame are engaged, the housing cover can seal the inside of the housing, which helps to prevent electrolyte from leaking from the inside of the housing. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] This application discloses a battery casing with leak-proof function. (Refer to...) Figure 3 , Figure 6 as well as Figure 7 A battery casing with anti-leakage function includes a casing 1, a lifting rod 3 slidably mounted on the casing 1, a casing cover 4 snapped onto the casing 1, a limiting mechanism 2 fixed on the casing cover 4, and a sealing mechanism 5 fixed on the casing 1 and the casing cover 4.

[0033] When the cover 4 and the frame 505 are engaged with the fixed frame 501 installed on the housing 1, the limiting block 506 can be positioned in the groove 502, thereby sealing the top of the housing 1 with the cover 4. The partition 503 facilitates the operator to place multiple batteries into the storage slot 504 in sequence, thereby facilitating the placement of the batteries into the housing 1.

[0034] A limiting block 506 is engaged in the groove 502. The part of the limiting block 506 that contacts the fixing frame 501 is set with an inclined structure. When the limiting block 506 is in the groove 502, the fixing frame 501 can limit the limiting block 506, thereby causing the frame 505 to engage with the fixing frame 501.

[0035] Reference Figure 2 , Figure 4 as well as Figure 5 The limiting mechanism 2 includes a locking block 203 and a slot 205. The locking block 203 is fixedly connected to the cover 4. The slot 205 is provided inside the locking block 203. The protrusion 204 is fixedly connected to the housing 1. The locking rod 202 is fixedly installed on the protrusion 204. The locking block 203 and the protrusion 204 are engaged. The locking rod 202 is threadedly connected to a fixing block 201.

[0036] When the cover 4 is engaged with the housing 1, the locking block 203 can engage with the protrusion 204. The locking block 203 can be fixed to the protrusion 204 by the fixing block 201.

[0037] The protrusion 204 is arranged in a cuboid structure, and the width of the protrusion 204 is greater than the diameter of the latch 202.

[0038] The protrusion 204 and the locking block 203 are engaged, which can limit the locking block 203 and thus limit the cover 4.

[0039] The top of the fixing block 201 abuts against the top of the locking block 203, and the fixing block 201 is set in a regular hexagonal structure.

[0040] When the fixing block 201 is threaded onto the side wall of the clamping rod 202, the fixing block 201 can limit the clamping block 203.

[0041] This application discloses the implementation principle of a battery plastic shell with anti-leakage function as follows: When sealing the top of the shell 1, the operator can engage the clip frame 505 fixed on the shell cover 4 with the fixed frame 501 installed on the top of the shell 1. Since the fixed frame 501 has several grooves 502, when installing the clip frame 505, the limiting block 506 fixed on the clip frame 505 can be aligned with the grooves 502, so that the limiting block 506 can be engaged inside the fixed frame 501. Since the contact part between the fixed frame 501 and the limiting block 506 is set with a slope structure, the fixed frame 501 limits the limiting block 506, and the shell cover 4 can be installed quickly. Since the fixed frame 501 is located at the top of the shell 1, when the clip frame 505 is engaged with the fixed frame 501, the shell cover 4 can seal the inside of the shell 1, which helps to prevent electrolyte from leaking from the inside of the shell 1.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
