Technical Field
[0001] The utility model belongs to the technical field of oven equipment, and particularly relates to a quick locking and releasing structure and an oven. Background Art
[0002] After the electrode is coated with slurry, it usually needs to be dried in an oven. The oven controls the internal temperature and humidity, heats the electrode to a certain temperature and maintains it for a certain time. The volatile organic substances contained in the slurry evaporate, and the electrode is baked.
[0003] In related technologies, to ensure the cleanliness of the air inside the oven and prevent contaminants such as dust, particles, and bacteria from adhering to the electrode surfaces, a filter is typically used inside the oven to filter the air. This filter can reduce the defective electrode rate caused by impurity contamination and extend the service life of the oven. The filter is placed within a frame within the oven and is typically locked to the frame with screws.
[0004] However, as a consumable part, the filter needs to be replaced after a period of use to ensure the cleanliness of the air filtration. The internal space of the existing oven is usually relatively small, and the operator needs to drill into the oven and use tools to loosen the screws to replace the filter. The small space inside the oven can easily lead to limited operation and pose safety risks. Utility Model Content
[0005] In order to address the shortcomings of the existing technology, the utility model provides a quick locking and releasing structure and an oven. The rotating shaft drives the cam to rotate to achieve the locking or releasing action of the filter and the frame. The operator does not need to drill into the narrow space inside the oven to replace the filter, which is convenient to operate and reduces safety risks.
[0006] The technical effects to be achieved by the present invention are achieved through the following technical aspects:
[0007] In the first aspect, the utility model provides a quick locking and releasing structure, comprising a frame for placing a filter, one side of the frame being the windward side, a sealing strip being provided between the outer wall of the filter close to the windward side and the frame; a rotating shaft rotatably connected to the frame and located on the side of the filter away from the windward side; and a cam sleeved on the rotating shaft, the cam comprising an abutting portion for pressing the filter against the sealing strip, the abutting portion abutting against the corresponding side of the filter.
[0008] In some implementations, the frame is detachably connected to a support, a fixing seat is provided on the support, and the rotating shaft passes through the fixing seat and is rotatably connected to the fixing seat.
[0009] In some implementations, a shaft sleeve is provided on the rotating shaft, and the shaft sleeve is located at the rotational connection between the fixing seat and the rotating shaft; a limit member is provided on the rotating shaft for limiting the movement of the rotating shaft, and the limit member is located on one side of the shaft sleeve.
[0010] In some implementations, a waist-shaped hole is provided on the fixing seat, and the fixing seat is detachably connected to the support at the waist-shaped hole.
[0011] In some implementations, a plurality of rotating shafts are provided, and the rotating shafts are spaced apart and distributed on a side of the filter away from the windward side.
[0012] In some implementations, a handle is provided on the rotating shaft, and the handle is located outside the frame. A locking assembly is provided between the handle and the rotating shaft, and the handle drives the rotating shaft to rotate via the locking assembly.
[0013] In some implementations, the cam is detachably connected to the rotating shaft.
[0014] In some implementations, a limiting groove is provided on the rotating shaft, the abutting portion is provided with a connecting key in the limiting groove, and the cam is detachably connected to the rotating shaft at the abutting portion.
[0015] In some implementations, a plurality of cams are provided, and the plurality of cams are spaced apart and sleeved on the rotating shaft.
[0016] In a second aspect, the present invention provides an oven comprising the above-mentioned quick locking and releasing structure.
[0017] In summary, the present invention has at least the following advantages:
[0018] 1. The quick locking and releasing structure provided by the present invention places the filter in the frame, and the outside air enters the filter from the windward side. The filter filters the impurities in the air, and the rotating shaft is rotated, and the rotating shaft drives the cam to rotate. The cam abuts against the filter at the abutting portion. The cam is in a locked state, and the abutting portion can press the filter against the sealing strip. The filter forms a seal between the windward side and the frame, and the filter is fixed. After the filter has been used for a period of time, the rotating shaft is rotated again to move the abutting portion away from the filter. The filter is released from the frame and the filter can be replaced. The operation is convenient. Compared with the traditional screw-locked filter and frame, there is no need for the operator to enter the interior of the oven, which saves time and effort, is conducive to improving work efficiency, and ensures the safety of the operator's filter disassembly and assembly operations.
[0019] 2. In the oven provided by the present invention, the filter is sealed and connected to the frame and can be easily assembled and disassembled.

DETAILED DESCRIPTION
[0029] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.
[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0031] Example 1:
[0032] Please see the attached Figure 1-3 The quick locking and releasing structure of the present invention includes a frame 1, a rotating shaft 2 is rotatably provided on the frame 1, and a cam 3 is sleeved on the rotating shaft 2 for pressing the filter 5 against the frame 1, which can push the filter 5 and the frame 1 to quickly lock or release. It is easy to operate and can be used in narrow installation spaces.
[0033] The frame 1 includes mutually connected side frames 11 and crossbeams 12. Specifically, the side frame 11 is a vertically arranged rectangular frame 1, and there are two side frames 11. A filter area 111 for placing the filter 5 is formed between the two side frames 11. It can be understood that this is not a specific limitation on the number of side frames 11. Technicians in the relevant field can adjust the number of side frames 11 according to the number or specifications of the actual filters 5 placed. Crossbeams 12 are set at both ends of the side frame 11 in the vertical direction. Specifically, the crossbeams 12 are set horizontally.
[0034] The side of the side frame 11 away from the filter area 111 is the windward side 13, and the outside air enters the filter area 111 from the windward side 13. A sealing strip 14 is provided on the outer wall of the side frame 11 in the filter area 111. The sealing strip 14 is located on the side of the frame 1 close to the windward side 13. Specifically, the sealing strip 14 is preferably, but not limited to, a rubber sealing strip 14.
[0035] The frame 1 is provided with a rotating shaft 2 in the filter area 111. When the filter 5 is placed in the filter area 111, the rotating shaft 2 is located on the side of the filter 5 away from the windward side 13. Specifically, the rotating shaft 2 is arranged parallel to the crossbeam 12. In other specific embodiments, one side of the rotating shaft 2 along the axial direction can extend to the outside of the frame 1 to facilitate the operator to lock or release the filter 5 by rotating the rotating shaft 2.
[0036] In a preferred embodiment, a support 15 is detachably connected to the side frame 11. The support 15 is specifically sheet-shaped. Furthermore, an adjustment hole is formed in the side frame 11, the length of which is aligned with the height of the side frame 11. The support 15 is adjusted at the adjustment hole to adjust its connection position with the side frame 11. The support 15 can be assembled with the side frame 11 at the adjustment hole using bolts. In some embodiments shown, two supports 15 can be provided, one on each side of the rotating shaft 2 along the axis to improve the rotational stability of the rotating shaft 2. A fixing seat 23 is provided on the support 15, and the rotating shaft 2 is passed through the fixing seat 23 and is rotatably connected to the fixing seat 23. In some specific embodiments shown, the fixing seat 23 is detachably connected to the support 15. Specifically, a waist-shaped hole 231 is provided on the fixing seat 23, and the length direction of the waist-shaped hole 231 is consistent with the axial direction of the rotating shaft 2. The fixing seat 23 is adjusted at the waist-shaped hole 231 to be detachably connected to the support 15. The fixing seat 23 can adjust the connection position with the support 15 along the length direction of the waist-shaped hole 231, thereby improving the adaptability with the filter 5.
[0037] A cam 3 is sleeved on the rotating shaft 2, and the cam 3 includes an abutment portion 31 for pressing the filter 5 against the sealing strip 14. In some specific embodiments shown, the abutment portion 31 is located at the distal end of the cam 3. When the rotating shaft 2 rotates, the rotating shaft 2 drives the cam 3 to rotate, and the abutment portion 31 abuts against the corresponding side of the filter 5.
[0038] During assembly and disassembly, the filter 5 is placed within the filter area 111 and the shaft 2 is rotated, which drives the cam 3 to rotate, causing the contact portion 31 to abut against the filter 5. This creates mutual compression between the filter 5 and the sealing strip 14, pressing the filter 5 against the sealing strip 14. This allows the filter 5 to be sealed to the sealing strip 14 on the windward side 13. The force applied to the cam 3 coincides with the center of gravity of the shaft 2, achieving a self-locking effect. The filter 5 is locked, allowing for quick installation and ensuring a good filtration effect. When the filter 5 needs to be replaced after a period of use, the shaft 2 is rotated a certain angle, driving the contact portion 31 of the cam 3 away from the corresponding side of the filter 5. The filter 5 is released from compression and unlocked, allowing the operator to replace the filter 5. Compared to traditional screw-locked filter 5 methods, operators do not need to enter the confined space inside the oven to operate. This makes assembly and disassembly of the filter 5 convenient and safe, effectively reducing the time spent on filter 5 replacement and improving operational efficiency.
[0039] Example 2:
[0040] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the rotating shaft 2 and the cam 3 of the utility model. Figures 3 to 6 .
[0041] The rotating shaft 2 of this embodiment includes an intermediate section 22 and a transition section 21. Specifically, the diameter of the cross section of the transition section 21 is smaller than the diameter of the cross section of the intermediate section 22. The rotating shaft 2 is rotatably connected to the fixed seat 23 at the transition section 21. In a preferred embodiment, the rotating shaft 2 is provided with a shaft sleeve 24 at the transition section 21. The shaft sleeve 24 is located between the rotating shaft 2 and the fixed seat 23. The rotating shaft 2 is rotatably connected to the fixed sleeve through the shaft sleeve 24, which is beneficial to reducing the friction of the rotation of the rotating shaft 2 and the powder loss caused by friction.
[0042] The rotating shaft 2 is provided with a limiting member 25 on the transition section 21. In some embodiments shown, the limiting member 25 is preferably, but not limited to, a retaining spring. The retaining spring engages with the transition section 21 and is located on one side of the rotating sleeve along the axis of the rotating shaft 2. The retaining spring cooperates with the transition section 21 to limit the movement of the rotating shaft 2, and the limiting member 25 serves to limit the position of the rotating shaft 2. In other embodiments, the limiting member 25 may be a rubber ring or the like.
[0043] In a preferred embodiment, a plurality of rotating shafts 2 are provided. These rotating shafts 2 are spaced apart along the height direction of the side frame 11 on the side of the filter 5 away from the windward side 13. This helps to enhance the contact force between the filter 5 and the sealing strip 14, ensuring the stability of the filter 5 when locked. Furthermore, a plurality of filter zones 111 can be provided within the frame 1 to facilitate adjusting the number of filters 5 according to actual production needs, thereby ensuring the air filtering effect. These filter zones 111 are arranged along the height direction of the side frame 11, and in this case, the filters 5 are stacked within the frame 1. A pad 151 is provided on the support 15, and the filter 5 is placed on the pad 151. This helps to maintain a certain distance between the filters 5 in adjacent filter zones 111 to facilitate heat dissipation, while also improving the stability of the filter 5 placement.
[0044] In a preferred embodiment, a handle 4 is provided at one end of the rotating shaft 2 in the axial direction. The handle 4 is located outside the frame 1, so that the rotating shaft 2 can be rotated by turning the handle 4. Furthermore, a locking assembly is provided between the handle 4 and the rotating shaft 2, and the handle 4 drives the rotating shaft 2 to rotate synchronously via the locking assembly. The handle 4 and the rotating shaft 2 are detachably connected. Specifically, the handle 4 can be threadedly connected to the rotating shaft 2. As shown in some specific embodiments, the locking assembly includes a button that is slidably disposed on the handle 4. A connecting shaft is provided on one side of the button. The connecting shaft is located inside the handle 4, and a locking gear is sleeved on the connecting shaft. A rotating gear is provided on the inner wall of the rotating shaft 2. When an operator presses the button, the button drives the connecting shaft and the locking gear toward the rotating gear, and the rotating gear meshes with the locking gear. At this time, the operator can rotate the handle 4 to drive the rotating shaft 2 to rotate synchronously, thereby locking and releasing the abutment portion 31. When the operator releases the button, the connecting shaft drives the locking gear to disengage the rotating gear. When the handle 4 is turned again, the rotating shaft 2 can remain stationary relative to the handle 4, thereby reducing the impact of accidental contact of the handle 4 on the locking or releasing of the cam 3 driven by the rotating shaft 2.
[0045] In a preferred embodiment, the cam 3 is detachably connected to the rotating shaft 2. Specifically, the cam 3 is detachably connected to the rotating shaft 2 at the abutting portion 31. The abutting portion 31 is preferably, but not limited to, detachably connected to the rotating shaft 2 using a secure screw, which is beneficial for extending the service life of the cam 3. In some specific embodiments shown, a limiting groove 26 is provided on the rotating shaft 2, and the abutting portion 31 is provided with a connecting key 32 in the limiting groove 26. The cam 3 ensures synchronous rotation with the rotating shaft 2 through the connecting key 32. Specifically, there can be a plurality of cams 3, and the plurality of cams 3 are spaced apart and sleeved on the rotating shaft 2. The plurality of cams 3 can increase the degree of tightness between the rotating shaft 2 and the filter 5. It is understandable that the operator can adjust the specific number of cams 3 according to actual production needs. For example, in some specific embodiments, there can be three cams 3.
[0046] Example 3:
[0047] This embodiment provides an oven based on the above embodiment, which can be used for drying the electrode. Figure 7 .
[0048] A drying oven includes a box body 6 and the above-mentioned quick locking and releasing structure, wherein a frame 1 is located in the box body 6, and a sealing door 61 is rotatably provided on the box body 6. When the sealing door 61 is opened, the filter 5 can be inserted into the filtering area 111, and the rotating shaft 2 and the cam 3 are rotated to lock the filter 5.
[0049] In the oven of the present invention, the filter 5 can be quickly locked, which is conducive to improving the convenience of replacing the filter 5. Traditional ovens rely on the installation and spatial accuracy of the frame 1, or use an adjustment mechanism to ensure that the filter 5 can be accurately inserted into the frame 1 and has good sealing and filtering effect. Compared with traditional ovens, through the arrangement of the rotating shaft 2 and the cam 3, the frame 1 can hold filters 5 of various specifications, thereby improving the flexibility of use. While being able to accommodate filters 5 of various specifications, it ensures that the filter 5 and the frame 1 are sealed and the filter 5 maintains a good filtering effect.
