Through the rotation adjustment of the support frame 10, the caulking hose 7 can be rotated to the front side of the mobile base 1 during the transfer of the device, thereby improving the convenience of operation during the transfer process;

[0025] A discharge head 12 is provided at the other end of the caulking hose 7, and a support frame 2 13 connected to the caulking hose 7 is provided on the bottom surface of the caulking hose 7 near the discharge head 12, and a handle 26 is fixedly provided on the support frame 2 13 away from the discharge head 12, a connecting frame 14 is provided on the bottom surface of the support frame 2 13, and a support frame 3 15 is connected to the bottom surface of the connecting frame 14 in a ball-jointed manner, and a connecting frame 2 16 with an inverted U-shaped structure is provided on the support frame 3 15, and rotatable walking wheels 17 are respectively provided at both ends of the connecting frame 2 16, and a positioning device for fixing the support frame 10 is also provided on the fixed seat 8.

[0026] like Figure 4 As shown, the positioning device includes a mounting seat 11 and a positioning pin 19. The mounting seat 11 is fixedly provided on the top surface of the fixing seat 8 corresponding to the support frame 10. A cavity 18 is opened in the mounting seat 11, and a positioning pin 19 which can slide left and right is passed through the cavity 18. A pressure plate 20 is fixedly provided on the positioning pin 19 near the bottom wall of the cavity 18, and a return spring 21 is wound between the pressure plate 20 and the top wall of the cavity 18. Pin holes 27 for the positioning pin 19 to pass through are respectively opened at both ends of the support frame 10. With the cooperation of the positioning pin 19 and the pin hole 27, the adjusted support frame 10 can be positioned. A blocking device for limiting the positioning pin 19 is also provided on the mounting seat 11.

[0027] Embodiment 2

[0028] Based on the first embodiment, Figure 4 and Figure 5 The specific structure of the blocking device is as follows:

[0029] The blocking device includes a cylinder 22 and an abutment rod 25. The cylinder 22 that is sleeved on the positioning pin 19 is fixedly provided on the mounting seat 11. Abutment groove 1 23 and abutment groove 24 are respectively opened on the cylinder 22 along its axial direction, and the depth of abutment groove 1 23 is greater than the depth of abutment groove 24. An abutment rod 25 matching with the abutment groove 1 23 is also fixedly provided on the positioning pin 19 corresponding to the abutment groove 1 23.

[0030] Through the above structure, the positioning pin 19 is pulled outward to separate the positioning pin 19 and the pin hole, and at the same time, the abutment rod 25 is extended to the outside of the abutment groove 1 23, and then the positioning pin 19 is rotated to drive the abutment rod 25 to rotate, so that the abutment rod 25 coincides with the abutment groove 2 24, and the external force on the positioning pin 19 is released. Under the action of the reset spring 21, the positioning pin 19 is driven to reset, and at the same time, the abutment rod 25 falls into the abutment groove 2 24. Since the size of the abutment groove 24 is smaller than the depth of the abutment groove 1 23, the positioning pin 19 can be effectively blocked and limited.

[0031] In specific use, the device is moved to a specified position, and the support frame 10 is first rotated and adjusted to rotate to the position on the rear side of the mobile base 1. When adjusting, the positioning pin 19 is first pulled outward to separate it from the pin hole 27, and then the positioning pin 19 is effectively limited by the cooperation of the abutment rod 25 and the abutment groove 24, so that the positioning pin 19 and the pin hole 27 are always in a separated state. Under the action of external force, the support frame 10 is rotated and adjusted. After the adjustment is completed, the adjusted support frame 10 is positioned by the cooperation of the positioning pin 19 and another pin hole 27;

[0032] During the caulking operation, the discharging head 12 is moved to a position overlapping with the gap, and the operator holds the handle 26 to move the supporting frame 2 13, and at the same time drives the discharging head 12 to perform a mobile filling operation at the gap. During the filling process, through the cooperation of the connecting frame 1 14, the supporting frame 3 15, the connecting frame 2 16 and the walking wheel 17, the supporting frame 2 13 can be effectively auxiliary supported during the moving process, thereby reducing the labor intensity of the operator and improving the practicality of the device.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
