This leads to a decrease in the sealing degree between the two and has a relatively adverse effect on the service life of the casing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a lithium battery casing with better protective performance. This addresses the problem mentioned in the background art that after prolonged use, the joint between the casing and the sealing plate is easily damaged or deformed due to prolonged direct exposure to the external environment and the influence of external impacts, resulting in a decrease in the sealing degree between the two and having a relatively adverse effect on the service life of the casing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery casing with good protective performance, comprising a main body and a shielding mechanism disposed on the outside of the main body to fill and shield the seam, ensuring the device's airtightness during long-term use. The shielding mechanism includes inserts symmetrically arranged and slidably connected to the inner side of a sealing cover frame. A protective frame is fixedly connected to one side of each insert, and a slide rail is slidably connected to the inner side of the protective frame. Several slide rails are symmetrically arranged.

[0013] Compared with the prior art, this utility model provides a lithium battery casing with better protective performance, and has the following beneficial effects:

[0014] 1. This utility model uses a spacer with a push plate fixedly connected to one side. A slide rail is symmetrically arranged on one side of the push plate. A protective frame is slidably connected to the outer side of the slide rail, and a slider is slidably connected to the inner side of the slide rail. A second screw is threadedly connected to the inner side of the slider, and the protective frame is threadedly connected to the outer side of the second screw. The lithium battery pack is placed inside the housing, and then a sealing cover frame is placed on top of the housing. The first screw is inserted into the housing and the sealing cover frame to connect and seal. Holding the outer wall of the protective frame, the insert slides into the outer side of the sealing cover frame. The insert naturally slides to the seam between the housing and the sealing cover frame. Rotating counterclockwise loosens each of the second screws, releasing the slider and reducing the pressure of the slider's outer wall on the inner wall of the slide rail. The force is applied to release the restriction on the position of the slide rail within the protective frame. Pushing the push button moves each slide rail towards the center within the insert until the spacer on one side of the push plate fully squeezes and fills the joint between the housing and the sealing cover frame. Then, the second screw is rotated clockwise to tighten the slider within the slide rail. This increases the pressure between the outer wall of the slider and the inner wall of the slide rail, fixing the horizontal position of the slide rail. Through the filling of the inner wall of the joint by the spacer and the protection of the protective frame against the outside, the joint can be effectively protected from damage or deformation caused by prolonged direct exposure to the external environment and external impacts. This can reduce the sealing degree between the two and ensure the service life of the equipment.

[0015] 2. This utility model features a push button with a slide rail fixedly connected to one side and a protective frame slidably connected to the outside of the slide rail, which effectively facilitates direct pushing of the slide rail by personnel.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a lithium battery casing with good protective performance, including a main body 1 and a shielding mechanism 2 disposed on the outer side of the main body 1 to fill and shield the joint, ensuring the device's airtightness during long-term use. The shielding mechanism 2 includes inserts 201 symmetrically arranged inside the sealing cover frame 102 and slidably connected to them. A protective frame 202 is fixedly connected to one side of the inserts 201. A slide rail 203 is slidably connected to the inner side of the protective frame 202. Several slide rails 203 are symmetrically arranged. A push plate 204 is fixedly connected to one side of the slide rail 203. A spacer 205 is fixedly connected to one side of the push plate 204. A slider 206 is slidably connected to the inner side of the slide rail 203. A second screw 207 is threadedly connected to the inner side of the slider 206. The protective frame 202 is threadedly connected to the outer side of the second screw 207. The protective mechanism ensures the device's airtightness during long-term use by sealing the joint with the spacer 205 and the outer side of the joint of the protective frame 202. To check the sealing at the joint, hold the outer wall of the protective frame 202 and slide the insert 201 into the outer side of the sealing cover frame 102. The insert 201 will naturally slide to the joint between the housing 101 and the sealing cover frame 102. Rotate counterclockwise and loosen each of the second screws 207 to loosen the slider 206, reducing the pressure of the outer wall of the slider 206 on the inner wall of the slide rail 203. This will release the restriction on the position of the slide rail 203 within the protective frame 202. Push the push button 4 to release the seal within the insert 201. Move each slide rail 203 towards the center until the spacer 205 on one side of the push plate 204 fully squeezes and fills the joint between the housing 101 and the sealing cover frame 102. Then rotate the second screw 207 clockwise to tighten the slider 206 inside the slide rail 203. This increases the pressure of the outer wall of the slider 206 on the inner wall of the slide rail 203, thus fixing the horizontal position of the slide rail 203. The spacer 205 fills the inner wall of the joint and the protective frame 202 protects the outside.

[0027] In this utility model, preferably, a handle 103 is fixedly connected to the top of the sealing cover frame 102, a first screw 104 is threadedly connected to one side of the sealing cover frame 102, several first screws 104 are symmetrically arranged, a housing 101 is threadedly connected to the outer side of one end of the first screw 104, and the sealing cover frame 102 is slidably connected to the outer side of the top of the housing 101. The lithium battery pack is placed inside the housing 101, and then the sealing cover frame 102 is closed on the top of the housing 101. The first screw 104 is inserted into the housing 101 and the sealing cover frame 102 to connect them and complete the sealing.

[0028] In this utility model, preferably, a washer 3 is movably connected to the outer side of the top end of the second screw 207. The washer 3 is located above the protective frame 202, which can effectively ensure the stability of the position of the second screw 207 during long-term use and reduce the degree of loosening.

[0029] In this utility model, preferably, a push button 4 is fixedly connected to one side of the slide rail 203, and an insert 201 is slidably connected to the outside of the slide rail 203, which can effectively and conveniently allow personnel to directly push the slide rail 203 to slide.

[0030] In this utility model, preferably, a sliding rod 7 is fixedly connected to one side of the push button 4, and several sliding rods 7 are symmetrically arranged. A protective frame 202 is slidably connected to the outside of the sliding rod 7, and a push plate 204 is fixedly connected to one end of the sliding rod 7, which can effectively ensure the stability of the push button 4 and the slide rail 203 during the sliding process.

[0031] In this utility model, preferably, a touch pad 5 is fixedly connected to one side of the inner side of the protective frame 202. Several touch pads 5 are symmetrically arranged. The touch pads 5 are made of flexible material, which can further enhance the protection capability of the corners.

[0032] In this utility model, preferably, a scale 6 is fixedly connected to one side of the slide rail 203, which can effectively mark the sliding stroke and position of the slide rail 203, making it convenient for personnel to determine the squeezing force of the pad 205.

[0033] In this utility model, preferably, the outer edge of the protective frame 202 is an arc-shaped structure, which can effectively reduce the scratches caused by relatively sharp edges and corners to the external environment.

[0034] The working principle and usage process of this utility model are as follows: In use, place the lithium battery pack inside the housing 101, then cover the top of the housing 101 with the sealing cover frame 102. Insert the first screw 104 into the housing 101 and the sealing cover frame 102 to connect and seal. Hold the outer wall of the protective frame 202 and slide the insert 201 into the outer side of the sealing cover frame 102. The insert 201 will naturally slide to the seam between the housing 101 and the sealing cover frame 102. Rotate counterclockwise and loosen each of the second screws 207 to loosen the slider 206, reducing the pressure of the outer wall of the slider 206 on the inner wall of the slide rail 203. This releases the restriction on the position of the slide rail 203 within the protective frame 202. Push the push button 4 to release the insert 201... The slide rails 203 are moved towards the center until the spacer 205 on one side of the push plate 204 fully compresses and fills the joint between the housing 101 and the sealing cover frame 102. Then, the second screw 207 is rotated clockwise to tighten the slider 206 inside the slide rail 203. This increases the pressure of the outer wall of the slider 206 on the inner wall of the slide rail 203, thus fixing the horizontal position of the slide rail 203. Through the filling of the inner wall of the joint by the spacer 205 and the protection of the outer wall by the protective frame 202, the damage or deformation of the material at the joint due to long-term direct exposure to the external environment and external impact can be effectively reduced, thus ensuring the service life of the equipment.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
