As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are considered to be exemplary in nature and not limiting.
[0018] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0019] As Figs. 1-3 shown, the embodiment of the present application provides a spray bottle nozzle falling test device, including cabinet 1, the inner side wall of cabinet 1 is fixedly connected with slide rail 2, the bottom of slide rail 2 is installed with motor 3, the output end of motor 3 is fixedly connected with lead screw 4, the outer side wall of lead screw 4 is threadedly connected with sliding block 5, sliding block 5 is slidingly connected on slide rail 2, the front surface of sliding block 5 is fixedly connected with fixed plate 6, the front surface of fixed plate 6 is installed with electric telescopic rod 7, the telescopic end of electric telescopic rod 7 is fixedly connected with rack 8, the front surface of fixed plate 6 is rotatably connected with rotating shaft 11, the outer side wall of rotating shaft 11 is fixedly connected with gear 12, gear 12 is meshingly connected with rack 8, the outer side wall of rotating shaft 11 is fixedly connected with connecting plate 13, the bottom of connecting plate 13 is installed with clamp 14.
[0020] In one embodiment, the front surface of rack 8 is provided with sliding groove 9, the inner side wall of sliding groove 9 is slidingly connected with limiting block 10, the rear surface of limiting block 10 is fixedly connected with fixed plate 6; through the setting of limiting block 10, limiting block 10 slides in sliding groove 9, the stability of rack 8 is improved.
[0021] In one embodiment, the front surface of cabinet 1 is hingedly connected with cabinet door 16, the front surface of cabinet door 16 is fixedly connected with handle 18; through the setting of handle 18, it is convenient to open and close cabinet door 16.
[0022] In one embodiment, the front surface of cabinet 1 is installed with first observation window 15, the front surface of cabinet door 16 is installed with second observation window 17; through the setting of first observation window 15 and second observation window 15, it is convenient to observe the inside of cabinet 1.
[0023] In one embodiment, the front surface of cabinet 1 is installed with instrument screen 19; the parameters such as swing speed and lifting frequency are displayed.
[0024] In operation, this invention works as follows: First, open the cabinet door 16 and fix the spray bottle bottom-up onto the clamp 14 for a drop test. During the lifting test, clamp the nozzle, then adjust the extension stroke and speed of the electric telescopic rod 7. The electric telescopic rod 7 drives the rack 9 to move, thereby driving the gear 12 to rotate, causing the connecting rod 13 to swing. The swing is set to 30 cm on each side, which simulates the displacement range that the spray bottle may experience due to shaking during daily use or transportation. 1000 reciprocating swings are performed. This large number of swings can fully simulate the shaking conditions that the spray bottle experiences during long-term use or complex transportation environments, in order to detect whether the nozzle will fall off under frequent swings. The swing angle is ±80 degrees from the vertical direction. This angle can simulate the large tilt that the spray bottle may experience in actual use scenarios, such as when holding the spray bottle for spraying operations. The angle is adjusted, and then the speed of motor 3 is controlled to drive the lead screw 4 to rotate. The lead screw 4 drives the slider 5 to move, set at 15 times per minute, to simulate the rhythm of the spray bottle being frequently lifted and lowered during transportation. The rising and falling speeds are both controlled at 0.5 m / s, which can reflect a certain level of transportation efficiency and apply a reasonable impact force to the connection between the nozzle and the spray bottle to test the stability of the nozzle under this dynamic force. Each lifting height is 0.8 meters to simulate the common operation scenario of lifting the spray bottle from the ground to a certain height and then lowering it during daily transportation. The state of the spray bottle nozzle is observed, and it is recorded whether the nozzle becomes loose, displaced, or even falls at different stages. The test scene is recorded by a high-speed camera to obtain the test state of the nozzle and record the corresponding experimental data nodes when problems occur in detail for subsequent analysis and improvement of product design.
[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
