Description

Technical Field

[0001] This utility model relates to the field of antifreeze technology for heating equipment, and more specifically, to an antifreeze device for gas-fired hot water heating equipment. Background Technology

[0002] The antifreeze device of gas-fired hot water heating equipment is a key component to ensure the normal operation of the equipment in low-temperature environments, avoid damage, and ensure the safety of the heating system. Its core function and specific value lie in preventing the equipment from freezing and cracking. Its main principle is that when the ambient temperature is below 0℃, the residual water in the heating system, especially in the pipes, may freeze and expand, leading to structural cracking of the equipment.

[0003] A search of existing publicly available technical documents reveals that Chinese Patent Publication No. CN205957490U discloses an antifreeze device for gas-fired hot water heating equipment and a gas-fired hot water heating equipment using this device. This technology prevents the pipes from bursting due to freezing of internal residual water, thus enabling the gas-fired hot water heating equipment to resist freezing and allowing it to be installed outdoors, improving its safety and reliability. However, this technology still has the following problems.

[0004] During the antifreeze process of gas-fired hot water heating equipment, insulation materials need to be placed outside the pipes. However, due to the long length of the pipes, multiple installation points are required, making it difficult to simultaneously lock the antifreeze parts of the gas-fired hot water heating equipment. This results in a significant decrease in locking efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: an antifreeze device for gas-fired hot water heating equipment, comprising a support frame and a locking screw. The locking screw is fixed to the inner wall of the support frame, and a synchronous locking assembly is provided on the outer wall of the locking screw. The synchronous locking assembly includes two locking nuts threaded to the outer wall of the locking screw. Each of the two locking nuts has a sleeve block on an adjacent side, and both sleeve blocks are slidably connected to the locking screw. A pressure strip is fixedly connected to the top of each sleeve block, and multiple locking pressure plates are fixedly connected to the upper surface of the pressure strip. Insulation cotton is installed on the inner wall of the locking pressure plate, and insulation pads are fixedly connected to both ends of the insulation cotton.

[0006] Preferably, both of the socket blocks are slidably connected to the support frame, and the outer wall of the socket block and the inner wall of the support frame are both smooth surfaces. Both of the pressure strips are slidably connected to the support frame, and a plurality of locking pressure plates are arranged equidistantly from left to right. Guide rings are fixedly connected to the inner wall of the insulation cotton near both ends, and the inner wall of the guide rings is a smooth surface.

[0007] A gap is provided between the two insulation pads, and mounting blocks are fixedly connected to both sides of the outer wall of the support frame; each mounting block has a mounting hole on its inner wall. One side of one of the mounting blocks is provided with a handle, which is fixedly connected to the support frame, and a limit ring is fixedly connected to the outer wall of the handle.

[0008] When using this technology, the insulation jacket is installed in conjunction with the gas-fired hot water heating equipment pipe. By rotating the two locking nuts, the two locking nuts press against the two connecting blocks. The two connecting blocks drive the two pressure strips to move closer together. The pressure strips drive multiple locking plates to press against the insulation jacket. The two insulation pads are pressed together to seal, so that the insulation jacket can be locked at multiple points simultaneously.

[0009] Preferably, a support block is fixedly connected to the upper surface of the insulation pad strip, and a guide support assembly is provided on the upper surface of the support block; the guide support assembly includes an L-shaped strip fixedly disposed on the upper surface of the support block, an inclined frame is installed on the inner wall of the L-shaped strip, and the L-shaped strip and the support block are fixedly connected to the inclined frame; a guide post is fixedly connected to one side of the inner wall of the L-shaped strip, and both locking pressure plates are slidably connected to the guide post, and both insulation pad strips are slidably connected to the guide post.

[0010] When this technology is in use, the locking pressure plate squeezes the insulation pad strip, the support block supports the tilting frame, the L-shaped strip provides support for the guide column, the two locking pressure plates slide along the outer wall of the guide column, and the two insulation pad strips slide along the outer wall of the guide column, ensuring that the two insulation pad strips are stably sealed along the specified path.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts a synchronous locking assembly. Under the action of the thread transmission force of the locking screw, the two locking nuts approach each other, the two sleeve blocks approach each other along the inner wall of the support frame, the pressure strip drives multiple locking pressure plates to squeeze the insulation cotton, and the two insulation pads are squeezed and sealed. The insulation cotton can achieve multi-point synchronous locking, so that the insulation cotton and the gas hot water heating equipment pipeline can be quickly and synchronously locked and installed. 2. This utility model adopts a support block to support the L-shaped strip, the support block to support the inclined frame, and the L-shaped strip to provide support force to the guide column. In this way, the two locking pressure plates slide along the outer wall of the guide column, and the two heat insulation pads are stably sealed according to the specified path, making the fastening more stable.

Detailed Implementation

[0018] 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.

[0019] As attached Figure 1 - Appendix Figure 5 The present invention relates to an antifreeze device for a gas-fired hot water heating equipment. The antifreeze device for the gas-fired hot water heating equipment is equipped with a synchronous locking component. The synchronous locking component enables the insulation cotton 7 to be synchronously locked at multiple points, so that the insulation cotton 7 and the gas-fired hot water heating equipment pipeline can be quickly and synchronously locked and installed. The specific structural configuration of the synchronous locking component is as follows.

[0020] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 4As shown, the locking screw 2 is fixed to the inner wall of the support frame 1, and the outer wall of the locking screw 2 is provided with a synchronous locking assembly. The synchronous locking assembly includes two locking nuts 3 threaded to the outer wall of the locking screw 2. Each of the two locking nuts 3 has a sleeve block 4 on an adjacent side. Both sleeve blocks 4 are slidably connected to the locking screw 2. A pressure strip 5 is fixedly connected to the top of each sleeve block 4, and multiple locking pressure plates 6 are fixedly connected to the upper surface of the pressure strip 5. Insulation cotton 7 is installed on the inner wall of the locking pressure plate 6, and insulation pads 8 are fixedly connected to both ends of the insulation cotton 7. Both sleeve blocks 4 are slidably connected to the support frame 1, and both the outer wall of the sleeve blocks 4 and the inner wall of the support frame 1 are smooth surfaces. Both pressure strips 5 are slidably connected to the support frame 1, and the multiple locking pressure plates 6 are arranged equidistantly from left to right.

[0021] In this embodiment, as shown in the appendix Figure 3 - Appendix Figure 4 As shown, guide rings 9 are fixedly connected to the inner wall of the insulation cotton 7 and near its two ends. The inner wall of the guide ring 9 is smooth so that the gas hot water heating equipment pipe can move along the guide ring 9 to achieve the guiding operation. There is a gap between the two insulation pads 8. Mounting blocks 10 are fixedly connected to both sides of the outer wall of the support frame 1. Each mounting block 10 has a mounting hole 13 on its inner wall so that an expansion bolt can be inserted into the mounting hole 13 inside the mounting block 10. The support frame 1 can be suspended for installation through the mounting block 10. One side of one of the mounting blocks 10 is provided with a handle 11. The handle 11 is fixedly connected to the support frame 1, and a limit ring 12 is fixedly connected to the outer wall of the handle 11 so that the hand can hold on the outer wall of the handle 11 and the limit ring 12 can limit the hand.

[0022] When using the antifreeze device for gas-fired hot water heating equipment, first, the insulation sleeve 7 is fitted onto the outer wall of the gas-fired hot water heating equipment pipe. At the same time, the gas-fired hot water heating equipment pipe moves along the guide ring 9, thus achieving the connection and installation of the insulation sleeve 7 with the gas-fired hot water heating equipment pipe. After the connection is completed, the hand is held on the outer wall of the handle 11, and the hand is limited by the limiting ring 12. At the same time, the handle 11 supports the support frame 1, increasing the stability of the support frame 1. Then, rotate the two locking nuts 3. Under the action of the thread transmission force of the locking screw 2, the two locking nuts 3 approach each other and press the two sleeve blocks 4 against each other. The two sleeve blocks 4 approach each other along the inner wall of the support frame 1. The two sleeve blocks 4 drive the two pressure strips 5 to approach each other. The pressure strips 5 drive multiple locking pressure plates 6 to press the insulation cotton 7, thus achieving compression and locking of the insulation cotton 7. At the same time, the locking pressure plates 6 press the insulation pads 8, and the two insulation pads 8 are squeezed and sealed. In this way, the insulation cotton 7 can achieve multi-point synchronous locking.

[0023] In this embodiment, as shown in the appendix Figure 5As shown, a support block 14 is fixedly connected to the upper surface of the insulation pad 8, and a guide support assembly is provided on the upper surface of the support block 14. The guide support assembly includes an L-shaped strip 15 fixedly installed on the upper surface of the support block 14, and an inclined frame 16 is installed on the inner wall of the L-shaped strip 15. Both the L-shaped strip 15 and the support block 14 are fixedly connected to the inclined frame 16. A guide post 17 is fixedly connected to one side of the inner wall of the L-shaped strip 15, and both locking pressure plates 6 are slidably connected to the guide post 17. Both insulation pads 8 are slidably connected to the guide post 17.

[0024] In use, the locking pressure plate 6 presses the insulation pad 8, which in turn supports the support block 14. The support block 14 supports the L-shaped strip 15, which in turn supports the tilting frame 16. The tilting frame 16 supports the L-shaped strip 15, and the L-shaped strip 15 provides support to the guide post 17. In this way, the two locking pressure plates 6 slide along the outer wall of the guide post 17, and at the same time, the two insulation pads 8 slide along the outer wall of the guide post 17. This process of guiding and pressing the two locking pressure plates 6 ensures that the two insulation pads 8 are stably sealed along the specified path.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
