[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0020] Please also refer to figure 1 , figure 2 and image 3 , a light bulb durability test device 100 provided in an embodiment of the present invention is used to test the durability of a light bulb (not shown), and the light bulb includes a threaded lamp cap (not shown) and a light emitting part (not shown) ). The light bulb durability testing device 100 includes a bottom plate 10 , a driving mechanism 20 , a clamping member 30 , a first elastic member 40 and a limiting mechanism 50 . The driving mechanism 20 drives the clamping part 30 to rotate, the clamping part 30 clamps the light bulb, and the first elastic part is compressed between the clamping part 30 and the driving mechanism 20, so that the clamping part 30 Clamp the bulb to reset. The limiting mechanism 50 is used to change the rotation direction of the clamping member 30 .
[0021] The bottom plate 10 is a square plate, and the driving mechanism 20 is fixedly connected to the bottom plate 10 . Certainly, in other implementation manners, the bottom plate may also be a circular plate. Specifically, a boss 11 and a pillar 12 are provided on the bottom plate 10 . The boss 11 is a square boss, the boss 11 extends vertically, and the driving mechanism 20 is fixedly connected to the boss 11 . Certainly, in other implementation manners, the boss may also be a circular boss. The pillar 12 is a square cylinder, the pillar 12 extends vertically, and a rectangular block 12 a is arranged at the end of the pillar 12 away from the bottom plate 10 . A threaded hole 12b extends horizontally from the rectangular block 12a. The threaded hole 12b is used for threadedly connecting the threaded lamp cap of the light bulb. Certainly, in other implementation manners, the threaded holes may also be arranged on the bottom plate and extend along the vertical direction.
[0022] The driving mechanism 20 is fixed on the boss 11 of the bottom plate 10 . In this embodiment, the driving mechanism 20 is a motor, of course, in other embodiments, the driving mechanism may also be a hydraulic machine. Specifically, the driving mechanism 20 includes a rotating shaft 21 and a body 22 that drives the rotating shaft 21 to rotate. The fuselage 22 is fixed on the top of the boss 11, and the rotating shaft 21 is arranged axially horizontally and in the same direction as the threaded through hole 12b. Of course, in other embodiments, if the threaded through hole extends vertically, the shaft also extends vertically in the axial direction, and the fuselage is fixed on the peripheral side of the boss. More specifically, the rotating shaft 21 can rotate along the direction a, and when the rotating shaft 21 stops rotating due to resistance when rotating along the direction a, it can immediately run in the opposite direction, that is, rotate along the direction b; when the rotating shaft 21 When it is rotated along the direction b, it will run in the opposite direction immediately after it stops rotating due to resistance, that is, it will continue to rotate along the direction a, and so on. And the rotation of the rotating shaft 21 drives the rotation of the clamping part 30 , so that the clamping part 30 rotates cyclically. And in order to allow the clamping member 30 to slide on the rotating shaft 21 , a sliding guide bar 21 a is provided along the parallel axial direction on the peripheral side of the rotating shaft 21 . Certainly, in other implementation manners, the peripheral side of the rotating shaft may also be provided with sliding slots.
[0023] The clamping member 30 includes a sleeve 31 and at least two second elastic members 32 . The sleeve 31 is sleeved on the rotating shaft 21 , and the at least two elastic members 32 are fixed on an end of the sleeve 31 away from the fuselage 22 . Specifically, the sleeve 31 is a circular sleeve. Certainly, in other embodiments, the sleeve may also be a square sleeve. The inner side of the sleeve 31 is provided with a chute 31a, and the chute 31a is slidably arranged with the guide bar 21a. Certainly, in other implementation manners, if a slide groove is provided on the rotating shaft, a guide slide bar may also be provided inside the sleeve. The at least two second elastic pieces 32 both extend axially along the sleeve 31 , and the at least two second elastic pieces 32 are bent along a bending line. The at least two second elastic members 32 form a lantern shape. In this embodiment, the at least two second elastic members are four bent metal sheets. The at least two second elastic members 32 are used to clamp the light emitting part of the bulb. In order not to damage the light-emitting part of the light bulb, a rubber pad is provided on a side close to the light-emitting part of the at least two second elastic members. Certainly, in other implementation manners, the at least two second elastic members may also be elastic plastic members. The holding member 30 is slidably disposed relative to the rotating shaft 21 , and at the same time, the holding member 30 rotates with the rotating shaft 21 , and the holding member 30 holds the light bulb to rotate.
[0024] The light bulb is clamped between the at least two second elastic members, and the light bulb can rotate relative to the fixing seat while reciprocating axially along the threaded hole 12b. The threaded lamp base of the bulb is threadedly connected to the threaded hole 12b. When the rotating shaft 21 rotates along the direction a, the threaded lamp cap is screwed into the threaded hole 12b along the direction a, and when the rotating shaft 21 rotates along the direction b, the threaded lamp cap is screwed out of the threaded hole along the direction b 12b. That is, the threaded lamp cap can be screwed in or out of the threaded hole 12b, which is convenient for testing its durability during use.
[0025] In order for the bulb to be screwed into the threaded hole 12b again after being unscrewed out of the threaded hole 12b, a restoring force must be exerted so that the bulb is screwed into the threaded hole 12b. Therefore, the first elastic member 40 is compressed between the clamping member 30 and the fuselage 22 . The first elastic member 40 is used to provide a restoring force for the clamping member 30 to move away from the body 22 , so that the bulb abuts against the threaded hole 12 b. In this embodiment, the first elastic member 40 is a rectangular spring, and the first elastic member 40 is sleeved on the rotating shaft 21 . Certainly, in other implementation manners, the first elastic member may also be an elastic plastic sleeve.
[0026]The limiting mechanism 50 functions to limit the rotation of the rotating shaft 21 . Specifically, the limiting mechanism 50 includes a stopper 51 and a baffle 52 . Specifically, the stopper 51 is fixed on the peripheral side of the sleeve 31. In this embodiment, the stopper 51 is integrated with the sleeve. Of course, in other embodiments, the stopper is also It may be welded to the sleeve. The baffle 52 is fixed on the bottom plate 10 . Specifically, the baffle plate 52 includes a first surface 521 and a second surface 522 oppositely disposed. Both the first surface 521 and the second surface 522 are parallel to the axial direction of the rotating shaft 21, and the distance from the edge of the first surface 521 and the second surface 522 close to the rotating shaft 21 to the rotating shaft 21 is less than The radius of rotation of the block 51 . In this embodiment, the baffle 52 is a rectangular plate, the baffle 52 extends in the same direction as the pillar 12 , and the first surface and the second surface are arranged on the same plate. Of course, in other embodiments, the baffle plate can also be two plates whose cross-sections are parallel to each other, and the first surface and the second surface can also be respectively arranged on the two plates, if the If the threaded hole extends vertically, the baffle may also extend horizontally. More specifically, when the stopper 51 rotates to the first surface 521 along the direction a with the sleeve 31, the rotating shaft 21 is resisted to stop rotating, and immediately runs in the reverse direction, and the stopper 51 immediately rotates in the opposite direction with the sleeve 31, and rotates to the second surface 522 along the direction b; when the stopper 51 rotates to the second surface 522 along the direction b with the sleeve 31, so that The rotating shaft 21 stops rotating due to the resistance, and immediately runs reversely, and the stopper 51 immediately reversely rotates, and rotates to the first surface 521 along the direction a. The stopper 51 rotates circularly so that the bulb can be screwed in or out of the threaded hole.
[0027] In order to start the light bulb durability testing device 100 at any time, the light bulb durability testing device 100 further includes a key switch 60 . The key switch 60 is installed on the boss 11 of the bottom plate 10 and is close to the side of the fuselage 22 . The key switch 60 is electrically connected to the driving mechanism 20 for turning on or off the driving mechanism 20 . Of course, in other embodiments, if the driving mechanism is a hydraulic machine, the bulb durability testing device can also be provided with a hydraulic valve, so that the driving mechanism can be stopped or run.
[0028] In the light bulb durability test device of the present invention, the light-emitting part of the light bulb is clamped by the clamping member, and the rotation of the rotating shaft drives the light bulb to rotate, so that the lamp cap of the light bulb is rotated and set in the threaded hole . The durability performance of the light bulb in use can be simulated to facilitate testing of its reliability.
[0029] The above description is a preferred embodiment of the present invention, and it should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also considered Be the protection scope of the present invention.
