Description

Technical Field

[0001] The utility model relates to the technical field of fireplaces, and more specifically to a heat-insulating handle mechanism for a fireplace. Background Art

[0002] A fireplace is an indoor heating device that is independent or built on a wall. It uses combustibles as energy and has a chimney inside. It originated from heating facilities in Western homes or palaces. The handle of the fireplace is installed on the fireplace door to open and close the door.

[0003] The fireplace will generate high temperature when in use, and the heat will be conducted to the fireplace handle. As the part that the user is in direct contact with the fireplace, if the surface temperature of the handle is too high, the user may be easily burned during use, affecting the user experience and safety.

[0004] However, the thermal insulation performance of existing thermal insulation fireplace door handles is still not ideal, and the temperature of the handle surface cannot be effectively and quickly reduced, resulting in the risk of burns to users when they touch it. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a fireplace insulation handle mechanism, which greatly improves the insulation effect of the fireplace handle through multiple insulation designs.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a fireplace insulation handle mechanism, including a handle body, the handle body is U-shaped as a whole, the handle body includes connecting rods at both ends and a gripping rod connecting the two connecting rods, a cooling chamber is opened inside the gripping rod, the cooling chamber extends to the upper and lower ends to an open opening, and a sealing plug is movably connected to the bottom of the cooling chamber, the cooling chamber is filled with cooling liquid, four support rods are arranged on the inner side of the connecting rod, and the other ends of the four support rods are each provided with a gripping piece.

[0007] The utility model is further configured as follows: two first sliding grooves are symmetrically and vertically opened at the lower end of the outer wall of the grasping rod, the upper ends of the two first sliding grooves are connected to a second sliding groove opened in an annular manner, the lower end of the sealing plug is provided with a connecting sleeve, and a sliding column is symmetrically arranged on the inner side of the connecting sleeve, and the sliding column is slidably matched with the sliding groove and the second sliding groove.

[0008] The utility model is further configured as follows: the gripping piece is in a concave structure.

[0009] The utility model is further configured as follows: the cooling liquid is cooling water.

[0010] The utility model is further configured as follows: the interior of the connecting rod is a hollow structure, and the interior of the connecting rod is filled with a heat insulating filler.

[0011] The utility model is further configured as follows: the heat insulating filler is glass fiber.

[0012] In summary, the utility model has the following beneficial effects:

[0013] The handle body is U-shaped as a whole, which is beneficial to reducing the heat conduction between the furnace door and the grip rod. The cooling liquid absorbs the heat on the surface of the grip rod to cool it down. When the furnace door is opened, the inside of the palm contacts the surface of the grip rod, and the fingers are placed on the grip to apply force. Compared with the direct contact of the whole hand with the surface of the grip rod, the heat conduction of the grip rod is further reduced through the support rod, and the temperature of the grip surface will be lower. After multiple insulation designs, the insulation effect of the fireplace handle is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figure 1 A fireplace insulation handle mechanism includes a handle body, which is U-shaped as a whole. The handle body includes connecting rods 1 at both ends and a gripping rod 2 connecting the two connecting rods 1. A cooling chamber 3 is opened inside the gripping rod 2. The cooling chamber 3 extends to the upper and lower ends to be open, and a sealing plug 4 is movably connected to the bottom of the cooling chamber 3. The cooling chamber 3 is filled with cooling liquid. Four support rods 5 are fixed on the inner side of the connecting rod 1, and the other ends of the four support rods 5 are fixed with gripping pieces 6.

[0021] Two first slide grooves 7 are symmetrically and vertically provided at the lower end of the outer wall of the gripping rod 2, and the upper ends of the two first slide grooves 7 are connected to a second slide groove 8 which is provided in an annular manner. A connecting sleeve 9 is fixedly provided at the lower end of the sealing plug 4, and a sliding column 10 is symmetrically fixed on the inner side of the connecting sleeve 9. The sliding column 10 slides in cooperation with the sliding groove and the second slide groove 8. After aligning the sliding column 10 with the first slide groove 7 and inserting it into the sealing plug 4, the sealing plug 4 and the connecting sleeve 9 are rotated as a whole so that the sliding column 10 rotates into the second slide groove 8. This can keep the lower end of the cooling chamber 3 sealed, and the sealing plug 4 is easy to disassemble and assemble, and is also very convenient when the inside of the cooling chamber 3 needs to be cleaned.

[0022] The gripping piece 6 is in a concave structure, which can provide a better gripping point, making it easier for the hand to hold the handle firmly, thereby increasing the stability and controllability of the grip.

[0023] The cooling liquid is cooling water, which has a high specific volume and can absorb more heat, and water resources are easy to obtain and safe.

[0024] The interior of the connecting rod 1 is a hollow structure, and the interior of the connecting rod 1 is filled with an insulating filler 11. The insulating filler 11 is glass fiber. Glass fiber has good thermal insulation properties. Filling the interior of the connecting rod 1 can effectively reduce heat conduction, reduce the surface temperature of the handle, effectively reduce the possibility of burns to the user, and improve the safety of the fireplace handle.

[0025] Working principle: The handle body is U-shaped as a whole. The connecting rod 1 is used to keep a certain distance between the gripping rod 2 that is in direct contact with the hand and the furnace door, which is beneficial to reducing heat conduction. Cooling liquid is injected into the cooling chamber 3 to absorb the heat on the surface of the gripping rod 2 for cooling. On the other hand, the four gripping pieces 6 correspond to the four fingers of the user respectively. The heat conduction of the gripping rod 2 is further reduced by the support rod 5. The temperature of the surface of the gripping piece 6 will be lower. When the furnace door is opened, the inner side of the palm contacts the surface of the gripping rod 2, and the fingers are placed on the gripping piece 6 to apply force, which effectively reduces the possibility of the user directly contacting the high-temperature surface compared to the whole hand directly contacting the surface of the gripping rod 2.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
