Description

Technical Field

[0001] The utility model relates to the technical field of handheld film-sticking suction pens, in particular to a handheld pressure-measuring suction pen. Background Art

[0002] The handheld pressure-measurable film suction pen can be used to absorb small parts and complete the attachment. During the attachment process, the attachment pressure can be observed to avoid damage to the target parts and products. It can also be used for transporting products and as a pressure gauge.

The first step is to suck up the film with a suction pen, and then apply pressure to the film with a handheld pressure gauge. The operation process is quite cumbersome, and the operator has difficulty controlling the downward pressure. At the same time, the pressure scale must be observed each time, so the film application pressure cannot be effectively controlled. Utility Model Content

[0038] See also Figures 1 to 10 As shown, the utility model provides a handheld pressure measuring pen, comprising:

[0039] Suction pen housing 1;

[0040] The telescopic block 2 is limited in its movement and is disposed inside the suction pen housing 1. The first end of the telescopic block 2 can slide along the length direction of the suction pen housing 1 to the outside of the first end opening of the suction pen housing 1.

[0041] The vacuum air inlet connector 3 is installed at the second end of the suction pen housing 1 and serves as an air outlet;

[0042] The suction pen suction cup 5 is installed at the first end of the telescopic block 2 away from the vacuum air inlet connector 3 and serves as an air inlet;

[0043] The air pipe 4 is arranged inside the suction pen housing 1, and the two ends of the air pipe 4 are respectively connected to the vacuum air inlet connector 3 and the suction pen suction cup 5;

[0044] The pressure limit block 13 is fixedly sleeved on the outside of the telescopic block 2 by a fixed top screw, and is used to limit the sliding range of the telescopic block 2 inside the suction pen housing 1;

[0045] The air circuit opening and closing component 14 is arranged inside the suction pen housing 1 and is used to open or close the air circuit. The air circuit can be opened or closed by the air circuit opening and closing component 14. When the air circuit is opened, suction can be generated by the suction pen suction cup 5 to complete the adsorption of the film to be attached. The telescopic block 2 can move to drive the suction pen suction cup 5 to move, thereby driving the movement of the film to be attached.

[0046] See also Figures 1 to 10 As shown, a first avoidance groove 16 is provided on the outer side of the suction pen housing 1, and a pressure scale pointer 7 is slidably provided inside the first avoidance groove 16, and one end of the pressure scale pointer 7 is fixedly connected to the telescopic block 2, and a pressure scale 6 is attached to the outside of the suction pen housing 1 near the first avoidance groove 16. Through this arrangement, the movement of the telescopic block 2 can drive the pressure scale pointer 7 to move, so that the pressure can be observed by the pressure scale 6, which is convenient for the operator to read the pressure.

[0047] See also Figures 1 to 10 As shown, a first elastic member 9 is provided inside the suction pen housing 1. The first elastic member 9 can be a spring. The two ends of the first elastic member 9 are respectively connected to the inner wall of the suction pen housing 1 and the outer wall of the telescopic block 2 extending to one end of the interior of the suction pen housing 1. The first elastic member 9 is used to rebound and reset the telescopic block 2 after it is forced to move toward the interior of the suction pen housing 1. When the telescopic block 2 is forced to move toward the first elastic member 9, the first elastic member 9 will store elastic potential energy. When the force on the telescopic block 2 disappears, the elastic potential energy stored in the first elastic member 9 in the previous process can reset the telescopic block 2.

[0048] See also Figures 1 to 10 As shown, a second avoidance groove 17 is provided on one side of the suction pen housing 1, a mounting groove 15 is provided inside the telescopic block 2, and the mounting groove 15 points to the direction of the second avoidance groove 17 and is in an open state. The air path opening and closing component 14 includes a trigger button 10, a movable block 11 and a second elastic member 12. The activity limit of the trigger button 10 is set inside the mounting groove 15, and the movable block 11 is slidably set inside the second avoidance groove 17, and one end of the movable block 11 is fixedly connected to the trigger button 10. The second elastic member 12 is set inside the mounting groove 15, and the two ends of the second elastic member 12 are respectively connected to the inner wall of the telescopic block 2 and the outer wall of the movable block 11. Fixed connection, the second elastic member 12 adopts a spring, and a vent 18 is provided on the movable block 11. The movable block 11 can be moved and adjusted to enable the suction pen suction cup 5 and the vacuum air inlet connector 3 to form an air passage 19 through the trachea 4 and the vent 18. The movable block 11 can be moved and adjusted to enable the suction pen suction cup 5 to move away from the trachea 4, thereby blocking the air passage 19 through the movable block 11. The air passage 19 can be blocked by pressing the trigger button 10 to move toward the second elastic member 12. When the driving force of pressing the trigger button 10 disappears, the elastic potential energy stored in the second elastic member 12 can reset the trigger button 10, so that the air passage 19 is in an open state.

[0049] See also Figures 1 to 10 As shown, the outer sleeve of the telescopic block 2 is provided with at least one set of sealing rings 8, which are used to reduce gas leakage of the telescopic block 2 in the suction pen housing 1 and improve the sealing performance.

[0050] See also Figures 1 to 10 As shown, the pressure limit block 13 can change the position of the pressure limit block 13 on the telescopic block 2 by adjusting the fixed top screw, thereby changing the sliding range of the telescopic block 2 inside the suction pen housing 1. The pressure limit block 13 limits the sliding range of the telescopic block 2 entering the suction pen housing 1, thereby limiting the pressure and avoiding excessive pressure.
