Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1-3, the utility model provides a door closure heat preservation device of horizontal gas boiler smoke box, including smoke box and with smoke box articulated door closure 1 of being connected, door closure 1 rotates around the articulated shaft level, door closure 1 rotates to on the smoke box and through bolt and smoke box fixed connection. Be provided with carriage 2 on the inside wall face of door closure 1, carriage 2's bottom is passed through runner assembly 3 and is connected with door closure 1 is articulated, runner assembly 3 includes matched with pivot 31 and sleeve pipe 32, carriage 2 specifically is "U" type frame that right angle channel-section steel welding formed, two ends of carriage 2 "U" type mouth respectively with two pivot 31 welded connection, two sleeve pipes 32 of position welded fastening that correspond pivot 31 on door closure 1's the bottom, pivot 31 is prefabricated in sleeve pipe 32. As shown in fig. 1, the support frame 2 can only rotate around the rotating assembly 3, the bottom end and the inner wall of the door cover 1 limit the rotating range of the rotating assembly 3, that is, the support frame 2 rotates to the horizontal position and is abutted to the bottom end of the door cover 1, the support frame 2 rotates to the vertical position and is abutted to the rear wall surface of the door cover 1, and therefore the support frame 2 can only rotate around the bottom end of the door cover 1 in the vertical and horizontal ranges.

After the supporting frame 2 rotates to the horizontal state, the heat insulation material is placed in the supporting frame 2, at the moment, the bottom edge of the supporting frame 2 supports the heat insulation material, and the heat insulation material is specifically glass fiber heat insulation cotton. Because the carriage 2 revolutes the rotation component 3 and is rotated to vertical in-process by the level, if not fixed insulation material, insulation material can receive gravity and descend, there is insulation material offset and can't play heat preservation effect or insulation material and drop from carriage 2, need install insulation material's problem again, so carriage 2 deviates from the one end welding of rotation component 3 has mounting 4, mounting 4 specifically is the sheetmetal of seting up the screw through-hole, the screw through-hole of bolt screw in mounting 4 supports insulation material tightly on carriage 2, realize insulation material and carriage 2's fixed. In order to further increase the fixing effect, the fixing members 4 are provided in two, and the two fixing members 4 are symmetrically arranged with reference to the center of one end of the supporting frame 2 departing from the rotating assembly 3. After the heat insulation material is fixed, the smoke box is fixedly connected with the door cover 1, and the part of the heat insulation material covering the opening of the smoke box has the heat insulation effect.

In order to fix the horizontal and vertical states of the support frame 2, the rotating assembly 3 further includes a cross pin 33, the rotating shaft 31 and the sleeve 32 are respectively provided with a cross hole and an opening matched with the cross pin 33, the cross pin 33 is simultaneously inserted into the cross hole and the opening, so that the cross pin 33 limits the relative rotation of the rotating shaft 31 and the sleeve 32, and further, when the support frame 2 is in the horizontal and vertical states, the cross pin 33 fixes the support frame 2 on the door cover 1.

The utility model discloses an insulation material's installation does: taking out the cross pin 33 for fixing on the sleeve 32, as shown in fig. 3, rotating the support frame 2 to a horizontal state, inserting the cross pin 33 into the pin hole, installing the thermal insulation material on the support frame 2, screwing the fixing member 4 with a bolt and tightly pressing the thermal insulation material on the support frame 2, pulling out the cross pin 33 after fixing the thermal insulation material, rotating the support frame 2 to a vertical position, and extending the cross pin 33 into the rotating shaft 31 and the sleeve 32 to complete the replacement of the thermal insulation material.
