Description

Technical Field

[0001] The utility model relates to the technical field of pole lamps, in particular to a stable lamp pole and lamp holder connection structure of the pole lamp. Background Art

[0002] Pole lamps are common lamps in our daily life. They are often installed outside houses for use. Their structure generally includes a lamp pole and a lamp holder. The lamp pole is relatively long and the lamp holder can be of various shapes. The lamp holder needs to be installed on the upper end of the lamp pole. During production, a connector needs to be set between the lamp pole and the lamp holder. In order to achieve the purpose of quick assembly, the connector usually includes a connecting rod and a sleeve. One end of the connecting rod is fixed to the upper end of the lamp pole by a threaded connection, and one end of the sleeve is fixed to the upper end of the lamp holder by a threaded connection. The other end of the sleeve is sleeved on the other end of the connecting rod, thereby completing the quick installation without the need to fix the connecting rod and the sleeve with screws. In order to achieve the damping effect, an O-ring will be installed between the connecting rod and the sleeve. However, the damping effect of the O-ring alone cannot make the lamp holder installed firmly. The lamp holder is prone to fall off due to external force or bad weather factors. Utility Model Content

[0005] Furthermore, the front end of the sleeve has a first threaded portion, which is screwed into the upper rear end of the lamp holder, and the rear end of the connecting rod has a second threaded portion, which is screwed into the upper front end of the lamp pole.

[0006] Furthermore, a first groove is provided in the rear end of the sleeve, and a second groove is provided on the outer wall of the front end of the connecting rod. Both the first groove and the second groove are for O-rings to be inserted.

[0007] Furthermore, the rear end of the slot is open, and the rear end of the slot extends to the rear end surface of the sleeve.

[0008] Furthermore, during assembly, the front end of the connecting rod is inserted into the rear end of the sleeve, and the steel ball slides from the rear end of the slot to the front end of the slot, and the steel ball is pressed against the inner wall of the slot by the elastic force of the spring.

[0009] The utility model provides a stable lamp pole and lamp holder connection structure for a lamp pole, and its beneficial effect is that not only the damping effect between the sleeve and the connecting rod is increased by the O-ring, but also the steel ball is inserted into the slot, and the steel ball is tightly pressed against the inner wall of the slot by the elastic force of the spring, thereby further improving the stability of the connection between the lamp pole and the lamp holder.

DETAILED DESCRIPTION

[0016] 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:

[0017] like Figure 1 — Figure 5 As shown, a stable lamp pole and lamp holder connection structure of a pole lamp includes a lamp pole 1 and a lamp holder 2, and also includes a connecting rod 3 and a sleeve 4. The rear end of the connecting rod 3 is fixed to the front upper end of the lamp pole 1 by a threaded connection, and the front end of the sleeve 4 is fixed to the rear upper end of the lamp holder 2 by a threaded connection. The sleeve 4 has a first through hole 41 that passes through from front to back, and the connecting rod 3 has a second through hole 31 that passes through from front to back. The front end of the connecting rod 3 is inserted into the rear end of the sleeve 4, and an O-ring 5 is clamped between the outer wall of the connecting rod 3 and the inner wall of the sleeve 4. A circular hole 32 is provided on the outer side of the front end of the connecting rod 3, and a spring 6 extending inwards and outwards is fixed in the circular hole 32. A steel ball 7 is fixedly connected to the outer end of the spring 6, and a slot 42 is provided on the inner wall of the rear end of the sleeve 4, and the steel ball 7 is clamped in the slot 42.

[0018] In order to facilitate the disassembly and assembly of the sleeve 4 and the connecting rod 3, the front end of the sleeve 4 has a first threaded portion 43, which is screwed into the rear upper end of the lamp holder 2, and the rear end of the connecting rod 3 has a second threaded portion 33, which is screwed into the front upper end of the lamp pole 1.

[0019] like Figure 3 — Figure 5 As shown, in order to facilitate fixing of the O-ring 5, a first groove 44 is provided in the rear end of the sleeve 4, and a second groove 34 is provided on the outer wall of the front end of the connecting rod 3. The first groove 44 and the second groove 34 are both for the O-ring 5 to be inserted. The second groove 34 is located behind the circular hole 32.

[0020] like Figure 4 As shown, the rear end of the slot 42 is open, and the rear end of the slot 42 extends to the rear end surface of the sleeve 4. During assembly, the front end of the connecting rod 3 is inserted into the rear end of the sleeve 4, and the steel ball 7 slides from the rear end of the slot 42 to the front end of the slot 42, and the steel ball 7 is pressed against the inner wall surface of the slot 42 by the elastic force of the spring 6. When the connecting rod 3 and the sleeve 4 are assembled, the steel ball 7 is aligned with the slot 42, and the rear end of the slot 42 is open to facilitate the insertion of the steel ball 7 into the slot 42.

[0021] The utility model provides a stable lamp pole and lamp holder connection structure of a lamp pole. Between the sleeve 4 and the connecting rod 3, not only the O-ring 5 is used to increase the damping effect between the two, but also the steel ball 7 is inserted into the slot 42. The steel ball 7 is tightly pressed against the inner wall of the slot 42 by the elastic force of the spring 6, thereby further improving the stability of the connection between the lamp pole 1 and the lamp holder 2.

[0022] 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.
