A lift-up yard lamp

Abstract

This utility model discloses a retractable courtyard light, comprising: a base with a cavity at its bottom, a cover plate detachably connected to the base and located below a battery, and a lower cylindrical column connected to the top of the base; an upper cylindrical column housed inside the lower cylindrical column, with a lamp body mounted at its top and its bottom electrically connected to the battery via a wire; and a groove on the outside of a connecting cylinder with a slider inside the groove. In this retractable courtyard light, when the upper cylindrical column extends, the connecting cylinder moves upward, reducing friction between the upper and lower cylindrical columns and facilitating the extension of the upper cylindrical column. When the upper cylindrical column retracts, it increases friction between the friction sleeve and the lower cylindrical column, further increasing friction between the upper and lower cylindrical columns and facilitating the slow downward movement of the upper cylindrical column. This slow downward movement prevents the connecting cylinder from squeezing and wearing down the wires, thus facilitating the use of the wires.

Description

Technical Field

[0001] This utility model relates to the field of courtyard lighting technology, specifically a lifting courtyard light. Background Technology

[0002] As an outdoor lighting device, courtyard lights play an important role in providing a safe and comfortable outdoor environment. Traditional courtyard lights are mostly fixed in one place and at a fixed height, which does not meet the needs of modern people's lives. Therefore, liftable courtyard lights have been developed based on the original design.

[0003] Existing retractable courtyard lights lack friction between the upper and lower cylindrical columns. When the clamp is released, the upper cylindrical column will quickly retract within the lower cylindrical column, which can easily damage the internal wiring. Furthermore, the rapidly descending light can easily come into contact with people, causing damage. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting courtyard light to solve the problems mentioned in the background art, such as the lack of friction between the upper and lower cylinders of the current lifting courtyard lights, the upper cylinder rapidly retracting in the lower cylinder when the clamp is loosened, which easily damages the wires inside the cylinder, and the rapidly descending light is likely to hit people and cause damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable courtyard light, comprising:

[0006] The base has a cavity at its bottom, and a battery is installed inside the cavity. A cover plate is provided below the battery and is detachably connected to the base. A lower cylinder is connected to the top of the base, and a clamping plate is fixedly connected to the top of the lower cylinder. A rotating sleeve is provided on the outside of the clamping plate.

[0007] An upper cylinder is located inside the lower cylinder, and a connecting cylinder is fixedly connected to the bottom end of the upper cylinder. A lamp body is installed at the top end of the upper cylinder, and the bottom end of the lamp body is electrically connected to a storage battery via a wire. A groove is provided on the outside of the connecting cylinder, and a slider is provided inside the groove. A friction sleeve is connected to the outside of the slider.

[0008] Preferably, the top of the lower cylinder is provided with a clamping plate at an equal angle, and the clamping plate has an elastic structure, and the outer side of the clamping plate has an inclined structure.

[0009] Preferably, the rotating sleeve is threadedly connected to the clamping plate, and the lower cylinder is fixedly connected to the upper cylinder through the clamping plate and the rotating sleeve.

[0010] Preferably, the upper cylinder and the lower cylinder form a telescopic structure.

[0011] Preferably, the outer side of the connecting cylinder is provided with a groove at an equal angle, and the inner side of the groove is provided with an inclined structure, and the bottom outer side of the groove is in contact with the inner wall of the lower cylinder column.

[0012] Preferably, the slider is movably connected to the connecting cylinder via a groove, and the slider and the friction sleeve are fixedly connected to form an integrated structure, and the friction sleeve has an elastic structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the upper cylinder of this lifting courtyard light extends, the connecting cylinder moves upward, so that the inclined structure in the groove no longer squeezes the slider, reducing the pressure of the slider on the friction sleeve, thereby reducing the friction between the upper and lower cylinders and facilitating the extension of the upper cylinder. When the upper cylinder retracts, the inclined structure in the groove of the connecting cylinder squeezes the slider, causing the slider to squeeze the friction sleeve, increasing the friction between the friction sleeve and the lower cylinder, thereby increasing the friction between the upper and lower cylinders and facilitating the slow downward movement of the upper cylinder. The slow downward movement of the upper cylinder avoids the connecting cylinder squeezing and wearing the wire, thus facilitating the use of the wire. The upper and lower cylinders are fixed by a clamp and a rotating sleeve, which facilitates the stability of the extension and retraction of the upper cylinder. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a lifting courtyard light, including: a base 1, a cavity 2, a battery 3, a cover plate 4, a lower cylindrical column 5, a clamping plate 6, a rotating sleeve 7, an upper cylindrical column 8, a lamp body 9, a wire 10, a connecting cylinder 11, a groove 12, a slider 13, and a friction sleeve 14.

[0021] The base 1 has a cavity 2 at its bottom, and a battery 3 is installed inside the cavity 2. A cover plate 4 is provided below the battery 3, and the cover plate 4 is detachably connected to the base 1. A lower cylinder 5 is connected to the top of the base 1, and a clamping plate 6 is fixedly connected to the top of the lower cylinder 5. A rotating sleeve 7 is provided on the outside of the clamping plate 6.

[0022] The upper cylinder 8 is located inside the lower cylinder 5, and the bottom end of the upper cylinder 8 is fixedly connected to the connecting cylinder 11. The top end of the upper cylinder 8 is equipped with the lamp body 9, and the bottom end of the lamp body 9 is electrically connected to the storage battery 3 through the wire 10. The connecting cylinder 11 has a groove 12 on its outside, and a slider 13 is provided inside the groove 12. A friction sleeve 14 is connected to the outside of the slider 13.

[0023] like Figure 1 , Figure 2 and Figure 3 The top of the lower cylindrical column 5 is provided with a clamping plate 6 at an equal angle. The clamping plate 6 has an elastic structure and the outer side of the clamping plate 6 has an inclined structure, which provides conditions for clamping and fixing the upper cylindrical column 8. The rotating sleeve 7 is threadedly connected to the clamping plate 6, and the lower cylindrical column 5 is fixedly connected to the upper cylindrical column 8 through the clamping plate 6 and the rotating sleeve 7, which facilitates the fixing of the upper cylindrical column 8. The upper cylindrical column 8 and the lower cylindrical column 5 form a telescopic structure, which facilitates the adjustment of the position and height of the lamp body 9.

[0024] like Figure 2 and Figure 4 The outer side of the connecting cylinder 11 is provided with a groove 12 at an equal angle, and the inner side of the groove 12 is set with an inclined structure. The bottom outer side of the groove 12 is in contact with the inner wall of the lower cylinder 5, providing conditions for the use of the friction sleeve 14. The slider 13 is movably connected to the connecting cylinder 11 through the groove 12, and the slider 13 and the friction sleeve 14 are fixedly connected to form an integrated structure. The friction sleeve 14 has an elastic structure, which facilitates increasing the friction between the lower cylinder 5 and the upper cylinder 8.

[0025] Working principle: such as Figure 2 As shown, when the lamp body 9 is extended, the upper cylinder 8 is pulled to extend the upper cylinder 8 in the lower cylinder 5. After the position and height of the lamp body 9 are determined, the rotating sleeve 7 is rotated to squeeze the clamping plate 6, thereby clamping and fixing the upper cylinder 8 to the lower cylinder 5 through the upper cylinder 8.

[0026] When the lamp body 9 is retracted, the rotating sleeve 7 is rotated in the opposite direction, causing the clamping plate 6 to loosen, thus allowing the upper cylinder 8 to fall under the action of gravity. As the upper cylinder 8 falls, it drives the connecting cylinder 11 to move downwards synchronously. Figure 4 As shown, the groove 12 in the connecting cylinder 11 is movably connected to the slider 13, and the inner side of the groove 12 has an inclined structure, which causes the slider 13 to be squeezed outward when the connecting cylinder 11 moves downward. In addition, the friction between the connecting cylinder 11 and the lower cylinder column 5 is increased by the contact friction of the friction sleeve 14, thereby reducing the downward movement speed of the upper cylinder column 8. The movable connection between the slider 13 and the groove 12 means that when the upper cylinder column 8 moves upward, the inclined structure in the groove 12 no longer squeezes the slider 13, reducing the friction between the friction sleeve 14 and the lower cylinder column 5, thus facilitating the upward movement of the upper cylinder column 8. When the connecting cylinder 11 moves downward, the bottom outer wall of the connecting cylinder 11 fits against the inner wall of the lower cylinder column 5, avoiding the wire 10 from being squeezed and worn. This is the whole working process of the lifting courtyard light. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
