Abstract

A bicycle seat tube lamp comprises a lamp shell and a light emitting device. The lamp shell is hollow and comprises an insertion portion and a lamp head. The upper portion of one side of the insertion portion is formed as a protruding portion. The lamp head is fixedly arranged on the protruding portion on one side of the insertion portion, and its width is larger than that of the insertion portion. A light-transmitting portion that can transmit light is arranged on the outer side of the lamp head. The upper end of the lamp head protrudes from the upper edge of the insertion portion, and a through hole is arranged on the upper end of the lamp head. The lower end of the lamp head protrudes from the lower edge of the protruding portion of the insertion portion, so that a coupling groove is formed between the lamp head and the insertion portion. The light emitting device is fixedly arranged in the lamp head and can emit light in the lamp head. When the utility model is combined with the seat tube, a warning light signal can be sent to the rear. Since the utility model can be firmly combined with the seat tube, even if the bicycle generates a large vibration when riding over a bumpy terrain, the utility model will not fall out of the clamping hole of the seat tube.

Description

bicycle seat tube light

technical field

The utility model relates to a bicycle lamp, in particular to a bicycle seat tube lamp, which can be firmly installed on the bicycle seat tube and is not easy to fall off.

Background technique

In addition to providing lighting, the lamps and lanterns of general bicycles provide warning functions more importantly. Since bicycle riders are not easy to actively pay attention to the vehicles coming from behind during riding, if the bicycle cannot issue an obvious warning to the rear Signal, then in the case of unclear line of sight such as night, the probability of an accident that the car from behind occurs to chase the bicycle tends to increase significantly.

Therefore, for the warning function of the car coming from behind, a bicycle seat tube light has been developed now, which is to dig a clamping hole on the rear side of the bicycle seat tube. For the light-emitting device that emits light, the opposite side of this side is corresponding to the clamping hole of the seat tube, and an elastic body is arranged around it, so that when the opposite side is embedded in the clamping hole of the seat tube lamp, the existing seat tube The light can be fixed in the clamping hole of the seat tube.

However, because the existing seat tube light is only fixed in the clamping hole of the seat tube by the elastic force of the elastic body, when the bicycle rides over a bumpy terrain, or the elastic body of the seat tube light deteriorates due to long-term use When the phenomenon occurs, the seat tube light is likely to fall out of the seat tube hole due to excessive vibration or insufficient fixation. This not only causes inconvenience in use, but also fails to provide a warning effect for the car coming from behind. .

Utility model content

In view of the fact that the existing seat tube light is easy to fall out of the clamping hole of the seat tube, the main purpose of the utility model is to provide a bicycle seat tube light, which can be firmly combined in the clamping hole of the seat tube and is not easy to fall off. out.

In order to achieve the above purpose, the bicycle seat tube lamp of the present utility model includes:

A bicycle seat tube light, comprising:

A lamp housing, which is hollow and includes an insertion part and a lamp head fixed on one side of the insertion part. The insertion part is a long column, and a battery chamber is formed inside the insertion part. A detachable battery cover is provided at the lower end to seal the battery chamber, and the upper part on one side of the insertion part is formed as a protrusion; the lamp head is fixed on the protrusion on the side of the insertion part, and its width is wider than that of the insertion part. The width of the part is large, the outer surface of the lamp head is provided with a light-transmitting part, the upper end of the lamp head protrudes from the upper edge of the insertion part, and a perforation is arranged at the upper end of the lamp head, The lower end protrudes from the lower edge of the protruding part of the insertion part, so that a joint groove is formed between the lamp head and the insertion part; and

A light-emitting device, which is fixed in the lamp head and includes a circuit board, more than one light bulb and a switch, the circuit board is arranged on the side of the lamp head close to the insertion part, the more than one light bulb and the circuit board Electrically connected and located in the lamp head, the switch is electrically connected with the circuit board and protrudes from the outer surface of the lamp head.

Preferably, the light bulb is a light emitting diode (LED) light bulb.

Preferably, the present invention further includes more than one battery, and the more than one battery is disposed in the battery chamber of the insertion part and is electrically connected to the circuit board.

Preferably, the inner surface of the lamp head is formed as an arc surface relative to the outer surface thereof.

Preferably, the switch is a push switch.

Preferably, the utility model further includes a bolt, and the bolt is passed through the hole at the upper end of the lamp head.

The specific effects that the utility model can achieve include:

1. When the utility model is inserted into the clamping hole of the seat tube, the bolt is threaded through the perforation of the lamp head and locked in the screw hole above the clamping hole of the seat tube, so that the upper end of the lamp head is locked on the seat tube and the edge of the seat tube below the clamping hole can be embedded in the combination groove between the lamp head and the insertion part, so the combination of the utility model and the seat tube is quite stable, even if the bicycle is riding over a bumpy terrain. When there is a relatively large vibration, the utility model will not fall from the clamping hole of the seat tube, so the loss of the utility model can be avoided.

2. Since the combination of the utility model and the seat tube is quite stable, the utility model can maintain the effect of sending warning lights to the rear at any time during the self-riding process, thereby improving the safety of bicycle riding.
