Detailed Embodiment

[0025] The embodiment of the present utility model provides a device for reducing the load of the operator of the two-component sealant applicator.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , which includes a fixing plate 8, a rubber hose 9 and a glue spraying device 11. A fixed frame 18 is fixedly sleeved outside the rubber hose 9. A sliding groove 14 is opened at the top of the fixing plate 8. An installation box 15 is arranged inside the sliding groove 14. A coiling rack 20 is rotatably installed inside the installation box 15. Two torsion springs 21 are installed between the coiling rack 20 and the installation box 15. A cloth belt 19 is fixedly connected between the coiling rack 20 and the fixed frame 18. The cloth belt 19 partially surrounds the outside of the coiling rack 20.

[0027] When the utility model is in use: Since two support frames 10 are sleeved outside the rubber tube 9, and both of the two support frames 10 are fixedly connected to the fixing plate 8, the pressure generated by the rubber tube 9 and the glue inside the rubber tube 9 acts on the fixing plate 8 under the action of the support frames 10, reducing the load that the operator needs to bear when operating the glue spraying device 11 rotatably installed at one end of the rubber tube 9; and the two support frames 10 only support and guide the rubber tube 9 without affecting the pulling use of the rubber tube 9; a handle 12 is fixedly connected to the bottom of the glue spraying device 11, and the operator can operate the glue spraying device 11 by holding the handle 12 to control the position and direction of the glue spraying device 11. Moreover, the bent rod 13 fixedly connected to the bottom of the fixing plate 8 has a certain curvature. The glue spraying device 11 can be rotated so that the handle 12 faces upward, the handle 12 is sleeved outside the bent rod 13, and the handle 12 is slid to the bent part of the bent rod 13, then the glue spraying device 11 can be placed on one side of the fixing plate 8, which is convenient for hanging the used glue spraying device 11 in the air.

[0028] A cloth belt 19 is fixedly connected between a coiling rack 20 rotatably installed inside the installation box 15 and a fixing rack 18, and the fixing rack 18 is fixedly sleeved outside the rubber tube 9. Therefore, when the operator operates the glue spraying device 11 by holding the handle 12 and moves the glue spraying device 11 up and down, since a part of the cloth belt 19 is wound around the outside of the coiling rack 20, as Figure 4 shown, the cloth belt 19 can be unfolded to meet the need for the downward movement of the glue spraying device 11. When the glue spraying device 11 moves upward, two torsion springs 21 installed between the coiling rack 20 and the installation box 15 rebound and wind up the cloth belt 19 to meet the need for the upward movement of the glue spraying device 11; and the two torsion springs 21 always apply an upward force to the coiling rack 20 during the operation of the glue spraying device 11. The upward force acts on the rubber tube 9 through the coiling rack 20, the cloth belt 19 and the fixing rack 18. The upward force received by the rubber tube 9 offsets part of the downward force generated by the rubber tube 9 and the glue inside the rubber tube 9 under the action of gravity, reducing the downward force received by the operator when operating the glue spraying device 11, reducing the load of the operator's operation, and slowing down the fatigue speed of the operator;

[0029] A limiting frame 16 is fixedly connected to the outside of the installation box 15, and the limiting frame 16 is sleeved outside the fixing plate 8. Under the limitation of the limiting frame 16 and the sliding groove 14, the installation box 15 can slide back and forth to meet the need for adjusting the front and back positions of the glue spraying device 11. Support wheels 22 are fixedly connected to both sides of the installation box 15, and the two support wheels 22 are respectively arranged on both sides inside the sliding groove 14. The support wheels 22 limit and support the installation box 15, reducing the friction generated between the installation box 15 and the fixing plate 8 and ensuring the stable and smooth movement of the installation box 15. Since the rubber tube 9 is rotatably connected to the glue spraying device 11 and the rubber tube 9 has a certain deformation ability, the orientation of the glue spraying device 11 can be adjusted at multiple angles to meet the need for glue spraying operation.

[0030] One end of the cloth belt 19 penetrates through the limit frame 16, and an elastic telescopic member 17 is fixedly connected between the limit frame 16 and the fixed frame 18. A part of the cloth belt 19 is arranged inside the elastic telescopic member 17 that can be telescoped. During the up and down movement of the fixed frame 18, the elastic telescopic member 17 expands and contracts, and the elastic telescopic member 17 shields and protects the cloth belt 19, avoiding the situation that the cloth belt 19 is not smoothly unwound and collected due to the adhesive liquid sticking to the outside of the cloth belt 19. Moreover, both the elastic telescopic member 17 and the cloth belt 19 can be deformed, without affecting the adjustment of the orientation of the spraying device 11.

[0031] In addition, a mounting rod 2 is fixedly connected to one side of the bottom of the fixing plate 8. A support rod 1 is rotatably sleeved on the outer bottom of the mounting rod 2. The fixing plate 8 supported by the cooperation of the support rod 1 and the mounting rod 2 can rotate. However, a sphere 5 is arranged on one side of each of a plurality of arc-shaped grooves 3 opened on the outer side of the mounting rod 2, as Figure 2 shown. One end of a spring 6 fixedly connected inside the fixed box 4 is fixedly connected to the sphere 5 to apply a force to the sphere 5, so that a part of the sphere 5 is arranged inside the arc-shaped groove 3 to abut against the mounting rod 2. A plurality of spheres 5 are annularly distributed on the outer side of the mounting rod 2, and a plurality of spheres 5 apply a certain force to the mounting rod 2. When the rotational force received by the mounting rod 2 exceeds a certain magnitude, the mounting rod 2 will rotate to push the sphere 5 back into the fixed box 4, so that the mounting rod 2 relatively stably maintains its existing state, and the angle of the fixing plate 8 fixedly connected to the mounting rod 2 is also relatively stable;

[0032] After the mounting rod 2 rotates to push the sphere 5 back into the fixed box 4, at this time, the force required to continue rotating the mounting rod 2 decreases. When the mounting rod 2 rotates again to align a plurality of spheres 5 with a plurality of arc-shaped grooves 3, the rebounding spring 6 pushes the sphere 5 into the arc-shaped groove 3, and the force required to rotate the mounting rod 2 increases again. The operator can choose to continue increasing the rotational force applied to the mounting rod 2, or adjust and operate the mounting rod 2 to keep the mounting rod 2 in place

[0033] In addition, a telescopic rod 7 is fixedly connected inside the fixed box 4, which can be telescoped. One end of the telescopic rod 7 is fixedly connected to the sphere 5, and the telescopic rod 7 restricts the movement track of the sphere 5 to ensure that the sphere 5 can enter the arc-shaped groove 3.
