Description

Technical Field

[0001] The utility model relates to the technical field of high pole lamps, in particular to a lifting type earthquake-resistant high pole lamp which can prevent a lamp panel from falling. Background Art

[0002] High pole lamps generally refer to new lighting devices composed of steel tapered lamp poles over 15 meters and high-power combined lamp frames. It consists of lamp holders, internal lamp electrical appliances, pole bodies and foundation parts.

[0003] Since the height of the lift-type high pole lamp needs to be adjusted according to actual conditions, the lamp panel is not completely fixed on the high pole lamp. Therefore, during the height adjustment or when the lifting component fails, the lamp panel is easily damaged by falling. Therefore, a high pole lamp that prevents the lamp panel from falling is needed to reduce the occurrence of this problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a lifting type earthquake-resistant high pole lamp which can prevent the lamp panel from falling.

[0005] The technical solution of the utility model is: a lifting type earthquake-resistant high pole lamp capable of preventing a lamp panel from falling, comprising a pole body, a lamp panel, a lifting assembly and an anti-falling tube sleeved on the pole body, the lamp panel comprising a light ring, a sleeve tube slidably connected to the pole body and a connecting rod connecting the light ring and the sleeve tube, the sleeve tube being arranged above the anti-falling tube; at least one group of anti-slip assemblies and a connecting piece are arranged on the anti-falling tube; the anti-slip assembly comprises a bracket fixedly arranged on the anti-falling tube, a cam rotatably arranged on the bracket and a friction block slidably connected to an opening provided on a side wall of the sleeve tube, an eccentric rod rotatably connected to a protrusion in the middle of the connecting piece is provided at an eccentric portion of the cam end face, and is used to drive the cam to rotate and push the friction block by utilizing the connecting piece.

[0006] Furthermore, the raised parts of the cam are distributed in a ring shape around the center of the cam.

[0007] Note: The annular distribution is more conducive to the cam to continuously push the friction block when the lamp panel falls, thereby preventing the raised part from failing to contact the friction block when the cam rotates, thereby affecting the realization of pushing.

[0008] Furthermore, the side surface of the friction block in contact with the rod body is made of elastic friction material, and the side surface of the friction block in contact with the cam is made of hard material.

[0009] Description: Limiting the material on both sides of the friction block allows one side to better provide friction resistance and the other side to better receive the pushing force of the cam, thereby effectively providing friction resistance between the friction block and the rod body.

[0010] Furthermore, the connecting member includes two hinged rods rotatably connected to the eccentric rod, one hinged rod is hinged to the lamp panel, and the other hinged rod is hinged to the anti-falling tube.

[0011] Description: The folding of the hinged rod can cushion the impact force when the lamp panel falls, further improving the anti-fall effect.

[0012] Furthermore, the side wall of the rod body is provided with a plurality of ratchets elastically connected thereto, the inner wall of the anti-fall tube is provided with an annular groove, a ring piece slidably connected to the annular groove, and a rack connected to the ring piece, the rack is meshed with the ratchets for transmission, and a shift block for driving the ring piece to rotate is provided on the bottom end face of the anti-fall tube.

[0013] Note: When adjusting the height of the lamp panel upward, the rack and the ratchet are in a non-engaged state, and the anti-fall tube rises normally with the lamp panel. When the height adjustment is stopped, the rack and the ratchet are engaged under gravity. Since the ratchet is fixed, the anti-fall tube remains fixed, that is, the anti-fall tube can only rise but not fall, and is supported by the engagement of the rack and the ratchet. When it needs to be lowered, move the dial block so that the rack and the ratchet are not in contact, then the lamp panel and the anti-fall tube can be adjusted to fall as a whole.

[0014] The beneficial effects of the utility model are:

[0015] The utility model provides a high pole lamp with a connecting piece and an anti-skid component, so that the anti-falling tube and the lamp panel can maintain a specific distance at any height, so that the lamp panel will not fall sharply, and the impact force of the lamp panel falling is reduced. When the lamp panel falls, the middle part of the connecting piece protrudes outward to drive the cam to rotate, and then the friction block is pushed by rotation to generate a gradually increasing friction resistance between the rod body and the lamp panel, thereby slowing down the falling of the lamp panel until the lamp panel stops falling, thereby improving the anti-falling effect.

[0022] The present invention will be further described in detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0023] Embodiment 1: A lifting type earthquake-resistant high pole lamp capable of preventing the lamp panel from falling, such as Figure 1 As shown, it includes a rod body 1, a lamp panel 2, a lifting component and an anti-falling tube 3 sleeved on the rod body 1, the lamp panel 2 includes a light ring 21, a sleeve tube 22 slidably connected to the rod body 1 and a connecting rod 23 connecting the light ring 21 and the sleeve tube 22, the sleeve tube 22 is arranged 1m above the anti-falling tube 3, the anti-falling tube 3 is provided with a buffer pad, the anti-falling tube 3 is provided with two symmetrical groups of anti-skid components and connecting parts; the anti-skid component includes a bracket 33 fixedly arranged on the anti-falling tube 3, a cam 34 rotatably arranged on the bracket 33 and a friction block 24 slidably connected to an opening provided on the side wall of the sleeve tube 22, and the eccentric portion of the end face of the cam 34 is provided with a friction block 24 slidably connected to the connecting hole The eccentric rod 32 rotatably connected to the protrusion in the middle of the connecting piece is used to drive the cam 34 to rotate and push the friction block 24 by using the connecting piece; the connecting piece includes two hinged rods 31 rotatably connected to the eccentric rod 32, one hinged rod 31 is hinged to the lamp panel 2, and the other hinged rod 31 is hinged to the anti-falling tube 3; the side surface of the friction block 24 in contact with the rod body 1 is a friction material with elasticity such as silicone rubber, and the side surface of the friction block 24 in contact with the cam 34 is a hard material such as steel. The lifting component adopts existing technology, such as a commercially available winch, which is buried in the rod body 1 and is fixedly connected to the top of the lamp panel 2 through two sets of winding ropes symmetrically arranged at an angle of 180°;

[0024] like Figure 4 and Figure 5 As shown, the side wall of the rod body 1 is provided with a plurality of ratchets elastically connected thereto, the inner wall of the anti-fall tube 3 is provided with an annular groove, a ring piece slidably connected to the annular groove, and a rack connected to the ring piece, the rack is meshed with the ratchets for transmission, and a shifting block for shifting the ring piece to rotate is provided on the bottom end face of the anti-fall tube 3.

[0025] The working principle of the lifting earthquake-resistant high pole lamp that can prevent the lamp panel from falling is as follows: when the lamp panel 2 is pulled up by a winch to adjust its height, the rack and the ratchet are in a non-engaged state, and the anti-falling tube 3 rises normally with the lamp panel 2. When the height adjustment is stopped, the rack and the ratchet are engaged under gravity. Since the ratchet is fixed, the anti-falling tube 3 remains fixed, that is, the anti-falling tube 3 can only rise but not fall. The lamp panel 2 and the anti-falling tube 3 are supported by the engagement of the rack and the ratchet. When it is necessary to descend, the dial block is moved so that the rack and the ratchet are not in contact, and the lamp panel 2 and the anti-falling tube 3 can be adjusted to fall as a whole.

[0026] Figure 1 When the lamp panel 2 falls due to a fault, the anti-falling tube 3 is fixed, and the two hinged rods 31 drive the eccentric rod 32 to protrude outward and drive the cam 34 to rotate. The cam 34 then contacts the friction block 24 and pushes it closer to the rod body 1, so that the friction block 24 gradually increases the friction resistance with the rod body 1 and the lamp panel 2 gradually stops falling. When the height of the lamp panel 2 is readjusted after falling, the gravity of the anti-falling tube 3 will automatically retract the hinged rod 31 inward, thereby returning to the initial state, preventing the friction resistance between the friction block 24 and the lamp pole 1 from being too large and affecting the height adjustment. Moreover, because the anti-falling tube 3 and the lamp panel 2 always maintain a specific distance, no matter at what height the lamp panel 2 falls, the impact force on the lamp panel 2 can be greatly reduced, thereby improving the anti-falling effect.

[0027] Embodiment 2: This embodiment differs from Embodiment 1 in that Figure 1 As shown, the raised portion of the cam 34 is distributed in a ring shape around the center of the cam 34 .

[0028] The working principle of this embodiment is different from that of Embodiment 1 in that the annular distribution is more conducive to the cam 34 to continuously push the friction block 24 when the lamp panel 2 falls, thereby preventing the raised part of the cam 34 from failing to contact the friction block 24 when the cam 34 rotates, thereby affecting the realization of pushing.

[0029] Embodiment 3: This embodiment is different from Embodiment 1 in that the winding ropes are provided in four groups and the four groups of winding ropes are spaced 90 degrees apart.

[0030] The working principle of this embodiment is different from that of Embodiment 1 in that the four sets of winding ropes enhance the pulling force of the winch on the lamp panel 2. If one set of winding ropes has a problem, the other three sets of winding ropes can also stably maintain the pulling force on the lamp panel 2, thereby improving the anti-falling effect of the high pole lamp.
