Problems solved by technology

[0004] The above-mentioned foaming tool with a safety control mechanism has the following problems: the adjustment part is installed on the fixed sleeve, in order to ensure the normal rotation of the adjustment part, there must be a gap between the adjustment part and the fixed sleeve, and the damping part of the safety control mechanism is located in the adjustment One side of the part, the force of the elastic part makes the damping part protrude from the side of the adjusting part and acts on the fixing sleeve, while the reaction force of the elastic part on the adjusting part can cause the position of the adjusting part to deviate from the center line of the fixing sleeve, and then This results in unbalanced force during the rotation of the adjustment member, and even causes a local stuck feeling when the adjustment cap is turned, which affects the user's hand feeling during operation

Embodiment 1

[0042] Such as Figure 10 As shown, the foaming gun includes a gun body 6 and a needle rod 7. The flow regulating device of the foaming gun is installed on the gun body 6 of the foaming gun for controlling the flow rate of the foaming gun and realizing the locking of the foaming gun . The flow regulating device of the foaming gun comprises a housing 1, a knob 2, a regulating rod 3, a cap body 4 and a damping structure.

[0043] Specifically, as figure 1 with Figure 5 As shown, one end of the housing 1 is threadedly connected to the gun body 6 , and the knob 2 is located at the other end of the housing 1 . Such as figure 1 with figure 2 As shown, an adjusting rod 3 is positioned in the circumferential direction of the housing 1 . Such as Figure 5 with Image 6 As shown, in this embodiment, the adjusting rod 3 has a connecting portion 31 with a hexagonal cross-section, and the casing 1 has a relief hole 11 matching the connecting portion 31 . In the actual production...

Embodiment 2

[0051] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, the elastic member is a spring, and the spring is evenly distributed on the end face of the housing 1 and the knob 2, and the spring The end is provided with a steel ball, and when the knob 2 is rotated, the steel ball can contact the blocking part 21 and compress the spring. When the knob 2 is rotated, the steel ball contacts the blocking portion 21 to elastically deform the spring, and the steel ball produces uniform resistance to the rotation of the knob 2 .

Embodiment 3

[0053] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, the damping structure includes an elastic member located on the inner side of the cap body 4, and the corresponding elastic member on the knob 2 There are blocking parts 21 distributed on the outer surface of the knob 2 along the circumferential direction at the position, and the elastic member can be in contact with the blocking parts 21 when the knob 2 is rotated. The elastic member is a cylindrical elastic sheet 5 made of elastic material, and at least two elastic protrusions 51 protruding inward are evenly distributed on the elastic sheet 5. When the knob 2 is rotated, the elastic protrusions 51 can contact the blocking part 21 and deform. .

Abstract

The invention provides a flow regulating device of a foaming gun, and belongs to the technical field of operation. The flow regulating device of the foaming gun solves the problem of uncomfortable hand touch when an existing flow regulating device of the foaming gun is used. The flow regulating device of the foaming gun comprises a shell and a rotary knob, wherein the shell and the rotary knob are arranged on a gun body, a regulating rod is located in the shell in the circumferential direction, one end of the regulating rod can make contact with the tail of a needle rod, the other end of the regulating rod is connected with the rotary knob through threads, a cap used for enabling the rotary knob and the shell to be limited in the axial direction is arranged between the shell and the rotary knob, and a damping structure is arranged at the position corresponding to the rotary knob inside the cap in the circumferential direction. The rotary knob and the shell are limited in the axial direction through the cap of the flow regulating device of the foaming gun, the length of the part, stretching out of the gun body, of the rotary knob remains unchanged in the rotating process of the rotary knob, the rotary knob is located at the most ideal position in design all the time, and the rotary knob can be rotated more easily. Resistance in the rotating process of the rotary knob is evener, and more comfortable hand touch of a user is achieved in operation. The regulating device of the foaming gun is convenient to mount, suitable for foaming guns of various types and good in universality.

Description

technical field [0001] The invention belongs to the technical field of operation, and relates to a foaming gun, in particular to a flow regulating device of the foaming gun. Background technique [0002] The foam gun is a tool for spraying foaming agent to the wall or the gap between doors and windows, and the foaming agent is sprayed to seal the gap or seal the gap. Existing foaming gun comprises gun body, gun barrel, needle bar and wrench, and needle bar is positioned at gun barrel and is hinged with wrench, controls the opening and closing of gun barrel by pulling wrench. [0003] In order to control the flow of the gun barrel, a flow regulating device is usually arranged on the foaming gun. For example, Chinese patent [Application No. 201090001226.9; Publication No. CN202983939U] discloses a foaming tool with a safety control mechanism. Components, and a safety control mechanism for preventing accidental retreat of the adjusting component. The specification of this pa...
