Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically a novel tension locking device. Background Technology

[0002] During the battery production process, the finished batteries need to be transported. Existing transport equipment consists of large mobile carts or forklifts. This method is suitable for transporting multiple battery boxes as a whole. However, when manually transporting or unloading batteries over short distances, only a single battery box can be transported at a time, and the battery box is large, manual transport is not feasible due to the lack of a lifting structure for the battery box, making it difficult to stabilize the battery box manually and posing a safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide a novel tension locking device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel tension locking device, comprising a battery box, with symmetrical grooves on both sides of the battery box, and locking bolts provided in the grooves. The locking bolts are inserted into a locking structure, and the locking structure includes a handle-type housing. A base plate is fixedly provided on one side of the handle-type housing, and a gourd-shaped opening is provided on the base plate. A fixing shell is fixedly provided on the base plate, and a tension spring is provided inside the fixing shell. One end of the tension spring is fixedly connected to the inner wall of the fixing shell, and the other end is fixedly connected to a tension plate.

[0005] Preferably, the locking bolt passes through the gourd-shaped opening, and the end of the locking bolt away from the battery box is threaded with a bolt cap.

[0006] Preferably, one side of the stretching plate extends through the handle housing, and the end of the stretching plate located in the central area of ​​the handle housing has an L-shaped structure.

[0007] Preferably, the side of the fixed shell facing the bottom plate has a stretching space.

[0008] Preferably, the handle-type housing is provided with a lifting hole.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the locking structure can be connected with the bolts on both sides of the battery box, making it easy to carry the battery box manually. Furthermore, the tension plate compresses the bolts due to the spring action, ensuring the stability of the connection and preventing the locking structure from coming loose during transportation, thus ensuring transportation safety.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Please refer to 1-4. One embodiment of this utility model is provided: a novel tension locking device, including a battery box 1. Grooves 2 are symmetrically opened on both sides of the battery box 1. Locking bolts 3 are provided in the grooves 2. The locking bolts 3 are inserted into a locking structure 4. The locking structure 4 includes a handle-type housing 41. A base plate 42 is fixedly provided on one side of the handle-type housing 41. A gourd-shaped opening 43 is opened on the base plate 42. A fixing shell 44 is fixedly provided on the base plate 42. A tension spring 45 is provided inside the fixing shell 44. One end of the tension spring 45 is fixedly connected to the inner wall of the fixing shell 44, and the other end is fixedly connected to a tension plate 46, allowing the locking bolts 3 to pass through the gourd-shaped opening 43. Then, the bolt caps of the locking bolts 3 are screwed on. The battery box 1 can be lifted upwards through the handle-type housing 41. During the lifting movement, the tension spring 45 pulls the tension plate 46 downwards, forming a compression contact with the locking bolts 3, thus forming a stable connection with the battery box 1.

[0017] The locking bolt 3 passes through the gourd-shaped opening 43. The end of the locking bolt 3 away from the battery box 1 is threaded with a bolt cap. The gourd-shaped opening 43 allows the locking bolt 3 to pass through easily, and the bolt cap is used to limit the gourd-shaped opening 43 to prevent the locking bolt 3 from coming out of the gourd-shaped opening 43.

[0018] One side of the stretch plate 46 extends through the handle housing 41. The end of the stretch plate 46 located in the central area of ​​the handle housing 41 has an L-shaped structure. The L-shaped structure allows the user to easily stretch the stretch plate 46 upwards, exposing the area of ​​the gourd-shaped opening 43 that is covered by the stretch plate 46, making it easier to insert the locking bolt 3 into the gourd-shaped opening 43.

[0019] The fixed shell 44 has a stretching space on the side facing the base plate 42, which facilitates the movement of the stretching plate 46; the handle-type shell 41 has a lifting hole, which is used to realize the lifting hook.

[0020] Working principle: When in use, the user stretches the L-shaped structure of the stretching plate 46 to expose the gourd-shaped opening 43. Then, the gourd-shaped opening 43 is aligned with the locking bolt 3 and inserted. The bolt head of the locking bolt 3 is rotated in to achieve fixation. After fixation is completed, the L-shaped structure of the stretching plate 46 is released. The stretching plate 46 is subjected to the action of the tension spring 45, which compresses the locking bolt 3 to complete the fixation of the battery box 1. The user can then move the battery box 1 by holding the handle-type outer shell 41.
