Description

Technical Field

[0001] The utility model relates to the technical field of cold bridge breaking, in particular to a cold bridge breaking flat box board. Background Technique

[0002] A cold bridge is a path for cold quantity transfer. In the HVAC industry, it specifically refers to the phenomenon that low-temperature air transfers energy along components with poor thermal insulation performance to the high-temperature end medium. Cold bridge breaking is the design of cutting off the cold bridge. An air-conditioning box body is formed by splicing multiple box board structures, and this box body is mostly applied to air-conditioning units. Due to the large temperature difference and air pressure difference between the inside and outside of the air-conditioning box body, in order to ensure the stability and sealing performance of the air-conditioning box body, the manufacturer has a very high standardization degree for the structure of the air-conditioning box board, and while optimizing the cost, it should have a good enough cold bridge breaking effect.

[0003] The cold bridge breaking box board is usually fixedly connected together by screws and an aluminum alloy frame. However, during use, the equipment will inevitably shake, and too many shaking times will cause the screws to loosen and then rotate. Once the screws rotate, gaps will appear between the aluminum alloy frame and the cold bridge breaking box board, resulting in the cold bridge not being completely cut off. Moreover, as time goes by, the gaps will become larger and larger, causing the cold bridge breaking to lose its function. Content of the Utility Model

Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 , a heat-break flat box board in this embodiment includes a heat-break box board 1 and a heat-break aluminum alloy frame 4. The heat-break box board 1 is a four-five profile. The heat-break box board 1 and the heat-break aluminum alloy frame 4 are internally thread-connected with self-tapping screws 5. The inside of the heat-break box board 1 is filled with a PVC profile strip 3. The PVC profile strip 3 is made of heat-insulating polyurethane foam. The inside of the heat-break box board 1 is provided with an anti-loosening mechanism 2 for pressing the self-tapping screws 5, and the inside of the heat-break box board 1 is provided with a sealing mechanism 6 for improving the sealing performance.

[0023] Please refer to Figures 2-3, To prevent the screw from loosening, the anti-loosening mechanism 2 in this embodiment includes two positioning blocks 206 slidably connected inside the heat-break bridge box plate 1. Two push plates 207 are slidably connected inside the positioning blocks 206. Magnets 208 are fixed on one side of the two push plates 207 close to the self-tapping screw 5. On the side of the two push plates 207 away from the magnets 208, movable plates 209 are fixed and slidably connected inside the positioning blocks 206. On the side of the movable plate 209 away from the push plate 207, there are no less than two compression springs 210 fixed. On the side of the positioning block 206 away from the magnet 208, an auxiliary block 201 is fixed.

[0024] On the side of the heat-break bridge box plate 1 away from the self-tapping screw 5, a positioning groove for the positioning block 206 to slidably connect is opened. The magnet 208 is slidably connected inside the positioning groove and magnetically attracts the nut of the self-tapping screw 5. Inside the positioning block 206, a movable groove for the movable plate 209 to slidably connect is opened. On the side of the positioning block 206 close to the magnet 208, a through hole for the push plate 207 to penetrate is opened, and the push plate 207 is slidably connected to the positioning block 206 through the through hole.

[0025] The anti-loosening mechanism 2 further includes a connecting plate 203 slidably connected inside the auxiliary block 201 and the positioning block 206. Inside the auxiliary block 201, a first connecting groove for the connecting plate 203 to slidably connect is opened. Inside the positioning block 206, a second connecting groove for the connecting plate 203 to slidably connect is opened. On the side of the connecting plate 203 close to the magnet 208, a connecting block 211 is fixed and slidably connected inside the positioning block 206. Inside the positioning block 206, a third connecting groove for the connecting block 211 to slidably connect is opened. On the side of the connecting block 211 away from the upper heat-break bridge aluminum alloy frame 4, a return spring 202 is fixed. On the side of the connecting block 211 away from the return spring 202, a clamping block 205 inserted inside the heat-break bridge box plate 1 is fixed. On the side of the connecting plate 203 away from the return spring 202, a pressing plate 204 slidably connected inside the auxiliary block 201 is fixed. Inside the auxiliary block 201, a pressing groove for the pressing plate 204 to slidably connect is opened. Inside the heat-break bridge box plate 1, a clamping groove for the clamping block 205 to be inserted is opened. The shape of the side of the clamping block 205 close to the magnet 208 is an inclined plane with a slope of sixty degrees. When the positioning block 206 is inserted into the positioning groove, the heat-break bridge box plate 1 retracts and presses the clamping block 205 along the inclined plane of the clamping block 205 into the positioning block 206, so that the positioning block 206 can be completely inserted into the positioning groove.

[0026] It can be seen that the anti-loosening mechanism 2 magnetically attracts the nut of the self-tapping screw 5 through the magnet 208, making it difficult for the self-tapping screw 5 to rotate. At the same time, through the cooperation of the push plate 207, the movable plate 209 and the compression spring 210, the magnet 208 is pushed, so that the magnet 208 presses the nut of the self-tapping screw 5, thereby making it difficult for the self-tapping screw 5 to move, and further preventing the self-tapping screw 5 from loosening and causing gaps.

[0027] Please refer to Figure 4 , in order to enhance the sealing performance, the sealing mechanism 6 in this embodiment includes not less than two sealing springs 601 fixed inside the heat-break bridge box board 1. A slide plate 602 is fixed on the side of not less than two sealing springs 601 away from the magnet 208. A sealing gasket 603 is fixed on the side of the slide plate 602 away from the sealing spring 601. A sealing strip 604 is adhered to the side of the heat-break bridge aluminum alloy frame 4 close to the self-tapping screw 5. The shape of the sealing gasket 603 is a cylinder with a hollow interior and both sides missing near and away from the sealing strip 604. The thickness of the sealing strip 604 is three millimeters.

[0028] A chute for the sliding connection of the slide plate 602 is provided inside the heat-break bridge box board 1. A communication hole for the self-tapping screw 5 to penetrate is provided on the side of the sealing strip 604 close to the sealing gasket 603, and the self-tapping screw 5 is in clearance fit with the sealing strip 604 through the communication hole.

[0029] Therefore, the sealing mechanism 6 initially seals the connection between the heat-break bridge box board 1 and the heat-break bridge aluminum alloy frame 4 through the sealing strip 604, and at the same time cooperates with the sealing spring 601, the slide plate 602 and the sealing gasket 603 to enhance the sealing performance, and makes the sealing gasket 603 always fit with the sealing strip 604 by pushing the sealing gasket 603 when a small gap appears due to the shaking of the self-tapping screw 5.

[0030] The working principle of the above embodiment is as follows:

[0031] (1) After connecting and fixing the heat-break bridge box board 1 and the heat-break bridge aluminum alloy frame 4 through the self-tapping screw 5, the magnet 208 is driven into the positioning groove by the positioning block 206. After the positioning block 206 completely enters the positioning groove, the magnet 208 is magnetically attracted to the nut of the self-tapping screw 5. At the same time, the clamping block 205 is inserted into the inside of the heat-break bridge box board 1 to fix the positioning block 206. The anti-loosening mechanism 2 magnetically attracts the nut of the self-tapping screw 5 through the magnet 208, making it difficult for the self-tapping screw 5 to rotate. At the same time, the magnet 208 is pushed through the cooperation of the push plate 207, the movable plate 209 and the compression spring 210, so that the magnet 208 presses the nut of the self-tapping screw 5, thereby making it difficult for the self-tapping screw 5 to move, and further preventing the self-tapping screw 5 from loosening and causing a gap.

[0032] (2) Adhere a sealing strip 604 at the connection between the thermal break aluminum alloy frame 4 and the thermal break box panel 1. Then, connect and fix the thermal break box panel 1 and the thermal break aluminum alloy frame 4 together with self-tapping screws 5. At this time, the sealing gasket 603 is compressed back into the interior of the thermal break box panel 1. Meanwhile, the sealing gasket 603 compresses the sealing spring 601 through the sliding plate 602. The sealing spring 601 pushes the sliding plate 602 through the rebounding force, and pushes the sealing gasket 603 through the sliding plate 602 to closely fit with the sealing strip 604. The sealing mechanism 6 preliminarily seals the connection between the thermal break box panel 1 and the thermal break aluminum alloy frame 4 through the sealing strip 604. Meanwhile, it cooperates with the sealing spring 601, the sliding plate 602 and the sealing gasket 603 to enhance the sealing performance, and enables the sealing gasket 603 to always fit with the sealing strip 604 by pushing the sealing gasket 603 when small gaps appear due to the shaking of the self-tapping screws 5.
