[0006] Market research revealed that existing retractable and tiltable lighting fixtures are expensive, structurally complex, and require cumbersome electronic control systems. There is a lack of simple, low-cost retractable lighting units on the market. Utility Model Content

[0007] To address the problems of complex structure and difficult operation of existing retractable tilt lamps, this invention provides a pneumatically retractable lamp assembly.

[0008] The technical solution adopted in this utility model is:

[0009] A pneumatically retractable lamp assembly includes a fixed shaft and a sliding base, the sliding base being slidably mounted on the fixed shaft, an upper fixed flange being connected to the top of the fixed shaft, and an upper flange fixing lug being provided on the upper fixed flange.

[0010] The sliding base is connected to one end of a retractable connecting rod, the other end of which is rotatably connected to a rotating connecting rod. One end of the rotating connecting rod is rotatably connected to the upper flange fixing lug, and a lamp assembly is connected to the outside of the rotating connecting rod.

[0011] A drive cylinder is connected between the retractable connecting rod and the fixed shaft. The rotating connecting rod is used to rotate under the pneumatic extension and retraction of the drive cylinder through the relative movement of the retractable connecting rod and the upper flange fixing lug.

[0012] Furthermore, the end of the drive cylinder is connected to a cylinder connector, and the cylinder connector is connected to the retracting connecting rod by a first connecting pin.

[0013] Furthermore, a first pin sleeve is fitted onto the first connecting pin, and the first pin sleeve is disposed between the retractable connecting rod and the first connecting pin.

[0014] Furthermore, the drive cylinder includes a cylinder body and a piston rod, the cylinder body is connected to a cylinder fixing joint via a second connecting pin, and the end of the piston rod is connected to the retracting connecting rod.

[0015] Furthermore, the cylinder fixing joint is connected to a connecting seat, the connecting seat is provided with a fixing plate, and the fixing shaft is disposed on the fixing plate.

[0016] Furthermore, a second pin sleeve is fitted onto the second connecting pin, and the second pin sleeve is disposed between the cylinder fixing joint and the second connecting pin.

[0017] Furthermore, a third connecting pin is connected between the sliding base and the retractable connecting rod, and the retractable connecting rod is respectively connected to both ends of the third connecting pin.

[0018] The beneficial effects of this utility model are:

[0019] This utility model's lamp assembly can retract and extend by driving a cylinder, thereby adjusting its lighting angle or retracting it for storage. The structure uses the extension and retraction of the cylinder to move a retraction connecting rod, which in turn moves a sliding base along a fixed axis, changing the relative distance between the sliding base and the upper fixed flange. Due to this change in movement, a rotating connecting rod, rotatably connected between the upper fixed flange and the retraction connecting rod, rotates around the upper flange fixing lug on the upper fixed flange, further rotating the lamp assembly connected to the rotating connecting rod, ultimately achieving the retraction or extension of the lamp assembly. This structure transforms the pneumatic driving force of the cylinder into rotational motion through a connecting rod structure. Simply retracting or extending the piston rod of the cylinder is sufficient to complete the retraction or extension of the lamp assembly, achieving automatic control of lamp assembly retraction and extension without the need for complex control circuits. Compared to existing lamp assembly structures, this design is simpler, lower in cost, and easier to operate and understand. Attached Figure Description

Detailed Implementation

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example 1

[0034] This embodiment is a pneumatically retractable lamp assembly; please refer to... Figures 1-10The system includes a fixed shaft 12 and a sliding base 13. The sliding base 13 is slidably sleeved on the fixed shaft 12. The top of the fixed shaft 12 is connected to an upper fixed flange 15, and an upper flange fixing ear 16 is provided on the upper fixed flange 15. One end of the sliding base 13 is connected to a retractable connecting rod 3, and the other end of the retractable connecting rod 3 is rotatably connected to a rotating connecting rod 5. One end of the rotating connecting rod 5 is rotatably connected to the upper flange fixing ear 16, and a lamp assembly 1 is externally connected to the rotating connecting rod 5. A drive cylinder 6 is connected between the retractable connecting rod 3 and the fixed shaft 12. The rotating connecting rod 5 is used to rotate under the pneumatic extension and retraction of the drive cylinder 6 through the relative movement of the retractable connecting rod 3 and the upper flange fixing ear 16.

[0035] Based on the above structure, the lamp assembly of this utility model can achieve the functions of retraction and extension by driving the cylinder 6, thereby adjusting its lighting angle or retracting it for storage. This structure, through the extension and retraction of the cylinder 6, drives the retraction connecting rod 3 to translate, and the retraction connecting rod 3 drives the sliding base 13 to slide along the fixed axis 12, changing the relative distance between the sliding base 13 and the upper fixed flange 15. Due to this change in movement, the rotating connecting rod 5, which is rotatably connected between the upper fixed flange 15 and the retraction connecting rod 3, is driven by the retraction connecting rod 3 to rotate around the upper flange fixing lug 16 on the upper fixed flange 15, further driving the lamp group 1 connected to the rotating connecting rod 5 to rotate, ultimately realizing the retraction or extension of the lamp group 1. This structure transforms the pneumatic driving force of the cylinder into rotational motion through the connecting rod structure. Only the piston rod of the cylinder 6 needs to be retracted or extended to complete the retraction or extension of the lamp group 1. Automatic control of the retraction and extension of the lamp group 1 can be achieved without setting up a complex control circuit. Compared with the existing lamp assembly structure, it is simpler, lower in cost, and easier to operate and understand.

[0036] Preferably, the rotatable connection between the retractable connecting rod 3, the rotating connecting rod 5 and other components of this utility model is a hinged connection.

[0037] As one embodiment, the lighting assembly of this utility model can be implemented as follows:

[0038] When the light fixture needs to be retracted while it is in the extended state (e.g.) Figure 1 (As shown in the unfolded state), at this time, the sliding base 13 is located on the fixed shaft 12 near the upper fixed flange 15. The piston rod of the control drive cylinder 6 retracts into the cylinder body. At this time, the piston rod drives the retraction rod and the sliding base 13 to move along the fixed shaft 12 from the position of the upper fixed flange 15 towards the connecting seat 9. The retraction connecting rod 3 drives the rotating connecting rod 5 to rotate around the upper flange fixing lug 16 of the upper fixed flange 15, thereby causing the lamp assembly 1 connected to the rotating connecting rod 5 to rotate from the unfolded state to the retracted state (as shown in the unfolded state). Figure 2(as shown in the retracted state); when the lamp needs to be unfolded while in the retracted state, the retraction action is reversed, causing the piston rod of the drive cylinder 6 to extend out of the cylinder body, thus unfolding the lamp assembly 1. The connection between the rotating connecting rod 5 and the lamp assembly 1 can be made using components such as screws 2.

[0039] Example 2

[0040] This embodiment is based on Embodiment 1, please refer to it. Figures 3-6 The end of the drive cylinder 6 is connected to a cylinder connector 17, and the cylinder connector 17 is connected to the retraction connecting rod 3 through a first connecting pin 4. Specifically, the end of the piston rod of the drive cylinder 6 is connected and fixed through the cylinder connector 17, and with the connection support of the first connecting pin 4, the stability of one end of the piston rod of the drive cylinder 6 during the extension and retraction movement can be maintained.

[0041] In a preferred embodiment, a first pin sleeve is fitted onto the first connecting pin 4, and the first pin sleeve is disposed between the retractable connecting rod 3 and the first connecting pin 4. The pin sleeve is used to reduce friction, transmit power, support and protect the connecting components, and is usually made of copper and its alloys, possessing mechanical properties such as high strength, high hardness and high toughness.

[0042] Example 3

[0043] This embodiment is based on Embodiment 1, please refer to it. Figure 7 The drive cylinder 6 includes a cylinder body and a piston rod. The cylinder body is connected to a cylinder fixing joint 7 via a second connecting pin 8, and the end of the piston rod is connected to the retracting connecting rod 3. The cylinder body of the drive cylinder 6 is connected to the cylinder fixing joint 7 via the connection and support of the second connecting pin 8, thereby fixing and supporting the position of the drive cylinder 6 and ensuring that the driving force of the drive cylinder 6 can be effectively applied to the retracting connecting rod 3.

[0044] In a preferred embodiment, the cylinder fixing joint 7 is connected to a connecting seat 9, and a fixing plate is provided on the connecting seat 9. The fixing shaft 12 is disposed on the fixing plate of the connecting seat 9. The structure of the connecting seat 9 fixes the relative position between the driving cylinder 6 and the fixing shaft 12, and can be configured such that the cylinder driving direction is parallel to the axial direction of the fixing shaft 12, thereby ensuring that the sliding base 13 can move stably along the axial direction of the fixing shaft 12 under the guidance of the fixing shaft 12, further improving the stability of the component operation.

[0045] In a preferred embodiment, a second pin sleeve 10 is fitted onto the second connecting pin 8, and the second pin sleeve 10 is disposed between the cylinder fixing joint 7 and the second connecting pin 8. The pin sleeve is used to reduce friction, transmit power, support and protect the connecting components, and is usually made of copper and its alloys, possessing mechanical properties such as high strength, high hardness and high toughness.

[0047] This embodiment is based on Embodiment 1, please refer to it. Figure 7 A third connecting pin 14 connects the sliding base 13 and the retractable connecting rod 3, with the retractable connecting rod 3 connected to both ends of the third connecting pin 14. The connecting pin connects the two components together and provides support for these components, making them more stable. Through this support, the connecting pin ensures that the connected components will not loosen or shift during movement, thereby maintaining the stability and reliability of the mechanical equipment. The connecting pin also positions the connected components, ensuring their correct position and orientation, guaranteeing that each component works according to the preset position and orientation, and avoiding functional failure or damage due to positional deviation.
