Description

Technical Field

[0001] The utility model relates to a pole lamp, in particular to an adjustable pole lamp. Background Art

[0002] The structure of the pole lamp in the prior art generally includes a lamp pole and a lamp holder, and the lamp holder is fixed at the upper end of the lamp pole. After the lamp holders of most pole lamps are fixed to the lamp pole, the angle cannot be adjusted. It is achieved by setting a protrusion at the rear of the upper end of the lamp holder, a threaded hole is set on the side wall of the protrusion, and a socket is set at the front of the upper end of the lamp pole, and a through hole is set on the side wall of the front upper end of the lamp pole. After the protrusion is inserted into the socket, a screw is passed through the through hole and then screwed into the threaded hole. This connection structure cannot adjust the angle of the lamp holder.

[0003] In order to meet the needs of different users, a small number of pole lamps have lamp caps designed as adjustable structures. A threaded portion is provided at the rear upper end of the lamp cap of such adjustable pole lamps, and a threaded hole is provided at the front upper end of the lamp pole. After the threaded portion is screwed into the threaded hole, the lamp cap is installed on the lamp pole. Because the two are connected by threads, the lamp cap can actually be rotated, which can adjust the angle to a certain extent. However, the price of adjusting the angle is that the threads need to be loosened, which results in a loose connection between the lamp cap and the lamp pole. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0018] like Figure 1 — Figure 5As shown, an adjustable pole lamp comprises a lamp pole 1, a lamp holder 2, a joint 3, an adapter sleeve 4 and a screw rod 5. The joint 3 is fixed to the upper end of the lamp pole 1, the upper end of the lamp holder 2 has an upper cover 6, the adapter sleeve 4 is installed between the rear end of the upper cover 6 and the front end of the joint 3, the screw rod 5 extends forward and backward through the joint 3 and the adapter sleeve 4 and then extends into the upper cover 6, and is fixed to the upper cover 6 by a threaded connection, the rear end of the upper cover 6 has a through hole 61, the front end of the adapter sleeve 4 extends into the through hole 61 and rotates with the through hole 61, and the front end of the through hole 61 has an annular blocking piece 62 for blocking the adapter sleeve 4.

[0019] like Figure 2 — Figure 4 As shown, the rear end and front end of the connector 3 respectively have a first through hole 31 and a second through hole 32, the rear end of the adapter sleeve 4 extends into the second through hole 32, the rear end of the second through hole 32 has two baffles 33, a slot 34 is formed between the upper ends of the two baffles 33, and a protrusion 41 is convexly provided on the rear end surface of the adapter sleeve 4, the shape of the protrusion 41 matches the slot 34 and is snapped into the slot 34. The adapter sleeve 4 and the connector 3 are connected together by snapping, and the two will not rotate relative to each other.

[0020] like Figure 2 , 4 As shown, the adapter sleeve 4 has a third through hole 42 that passes through the front and back, and the front end of the upper cover 6 has a threaded hole 63, and the rear end of the threaded hole 63 is open. The screw rod 5 passes through the first through hole 31, the second through hole 32, the third through hole 42, and the through hole 61 and then extends into the upper cover 6. The front end of the screw rod 5 is screwed into the threaded hole 63 by a threaded connection, and the rear end of the screw rod 5 is pressed on the rear end outer wall of the connector 3. The screw rod 5 firmly connects the upper cover 6, the adapter sleeve 4, and the connector 3 together.

[0021] like Figure 2 , Figure 4 , Figure 5 As shown, the front end of the adapter sleeve 4 is circular, the through hole 61 is a circular hole, a stopper 621 is convexly provided at the rear upper end of the annular baffle 62, and a stopper 43 is convexly provided on the front end surface of the adapter sleeve 4. The stopper 43 leans against the rear end surface of the annular baffle 62, and the stopper 43 is used to stop the stopper 621. When the lamp holder 2 rotates, the stopper 621 will rotate, and after rotating to the position of the stopper 43, the stopper 43 will block the stopper 621, preventing the lamp holder 2 from continuing to rotate, that is, the rotation angle of the lamp holder 2 can be limited to a certain extent.

[0022] like Figure 2 and Figure 4 As shown, an O-ring 7 is clamped between the front end of the adapter sleeve 4 and the inner wall of the through hole 61, and the front end side wall of the adapter sleeve 4 has an annular groove 44 for the O-ring 7 to be clamped. The O-ring 7 can play a damping role when the lamp holder 2 rotates.

[0023] The utility model provides an adjustable pole lamp. After the screw rod 5 is loosened, the lamp holder 2 can be rotated relative to the adapter sleeve 4. After rotating to a suitable angle, the screw rod 5 can be tightened, so that the lighting angle of the lamp holder 2 can be adjusted conveniently and the use is also convenient.

[0024] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the description and drawings of the present invention should be included in the patent protection scope of the present invention.
