[0032] As Figures 1-6 shown, an embodiment of the present utility model provides a fluid heat preservation device for a new type of nozzle, including: a heat preservation component 1, and the heat preservation component 1 includes: a raw material delivery pipe 11, on which an outer cylinder 12 is provided; an outer cylinder 14, arranged inside the outer cylinder 12; a heat insulation cavity 13, opened between the side wall of the outer cylinder 12 and the side wall of the outer cylinder 14; a heating element 15, arranged on the outer peripheral side of the outer cylinder 12; a heating wire 16, arranged inside the outer cylinder 12; and the heating wire 16 is fixedly connected to the heating element 15; an adjusting component 2 is further arranged on the raw material delivery pipe 11, and the adjusting component 2 includes: a discharge port 21, arranged at one end of the raw material delivery pipe 11; a first discharge cavity 22, opened inside the discharge port 21; a second discharge cavity 23, opened inside the discharge port 21; a threaded cylinder 24, arranged at one end of the raw material delivery pipe 11, and the raw material delivery pipe 11 is communicated with the first discharge cavity 22 through the threaded cylinder 24; a partition plate 27, arranged inside the discharge port 21; an adjusting part 25, threadedly connected to the outer peripheral side of the threaded cylinder 24; a connecting part 26, arranged on the adjusting part 25, and the partition plate 27 is arranged on the connecting part 26.

[0033] This device is a heat preservation device for a road surface caulking gun. The raw material delivery pipe 11 is connected to the original caulking gun. When using this device, the caulking material will enter from the raw material delivery pipe 11 and finally flow out through the discharge port 21. A heat preservation component 1 is arranged in the middle to heat and keep it warm, preventing it from being blocked due to cooling. It is heated by the heating element 15 and the heating wire 16 and then kept warm. Among them, the heat preservation component 1 of this device is provided with two layers, and a heat insulation cavity 13 is arranged in the middle to reduce the heat loss speed and achieve the heat preservation effect.

A clamping block 34 is arranged at the top of the plugging groove 32, and it is fixed by the force generated by the spring pull rod 33. When removing, turn the handle 38 to drive the gear 361 to rotate, thereby driving the rack 36 engaged therewith to move, and then driving the clamping part 35 originally above the clamping groove to disengage from the clamping groove, and finally the whole device can be removed.

[0037] As Figure 5 As shown in the figure, in this embodiment, two spring pull rods 33, two clamping blocks 34 and two racks 36 are provided, which can increase the fixing stability.

[0038] As Figure 5 As shown in the figure, in this embodiment, the contact surfaces of the clamping block 34 and the clamping part 35 are both arc surfaces, so that the clamping part 35 can be directly inserted when placing, which is convenient and fast.

[0039] As Figure 5 As shown in the figure, in this embodiment, a plurality of bolt holes are further opened on the fixing seat 31, which is convenient to fix the fixing seat 31 on the caulking vehicle.

[0040] As Figure 4 As shown in the figure, in this embodiment, the fixing component 3 further includes: a spring member 39, arranged on the fixing seat 31. The spring member 39 makes the clamping part 35 pop out directly when turning the handle 38 to remove, which is more convenient to remove.

[0041] Practical principle: The device is an insulation device used in a pavement caulking gun. The raw material conveying pipe 11 is connected to the original caulking gun. When the device is used, the caulking material will enter from the raw material conveying pipe 11 and eventually flow out through the discharge port 21. An insulation component 1 is arranged in the middle to heat and insulate it to prevent the nozzle from being blocked due to cooling. It is heated by the heating element 15 and the electric heating wire 16 and then insulated. The insulation component 1 of the device is provided with two layers, and an insulation chamber 13 is arranged in the middle to reduce the heat loss rate and achieve insulation effect. At the same time, the device is provided with an adjustment component 2, and its main discharge port 21 is provided with a first discharge chamber 22 and a second discharge chamber 23, which are separated by a partition plate 27. The first discharge chamber 22 is a conical discharge port 21, which is better adapted to small gaps. When a flat mouth is needed, the adjustment member 25 is rotated to drive the connecting member 26 and the partition plate 27 to move to one side. The first discharge chamber 22 and the second discharge chamber 23 are connected. At this time, the discharge port 21 forms a flat mouth shape, so as to adapt to wide cracks. It not only solves the problem that the discharge port 21 cannot be replaced in the original solution, but also is more convenient for adjustment. The conversion can be achieved without replacing the discharge port 21, which greatly improves its convenience. At the same time, the device is also provided with a fixing component 3. The fixing component 3 is mainly used to lock the entire device so that it can be more stably fixed on the caulking vehicle. The fixing component 3 mainly makes the clamping part 35 fixed on the outer cylinder 12 inserted into the plug-in groove 32. A clamping block 34 is provided on the top of the plug-in groove 32. The force generated by the spring pull rod 33 is used to clamp it and fix it. When removing it, turn the handle 38 to drive the gear 361 to rotate, thereby driving the rack 36 meshing with it to move, thereby driving the clamping part 35 originally located above the clamping groove to disengage from the clamping groove, and finally the entire device can be removed.

[0042] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
