It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
Referring to fig. 1-3, a tube reading light is shown.
The reading lamp structure is composed of a lamp holder component 1, a shell component 2, a hose component 3 and an electric connector 4. The base part 1, the housing part 2 and the electrical connector 4 are arranged in this order from front to back.
The base part 1 is composed of a base shell 11, a base LED12, a base knob 13 and a base potentiometer 14. The base housing 11 extends in the front-rear direction. A cap locking groove is formed on the rear end portion of the cap housing 11. The lamp cap potentiometer 14 adopts a potentiometer with a switching function. The rotating shaft of the lamp cap potentiometer 14 and the lamp cap knob 13 act synchronously. The lamp cap knob 13 is rotated, so that the on-off and the brightness of the lamp cap LED12 can be controlled through the lamp cap potentiometer 14.
The housing member 2 is composed of a lamp housing 21, a spring assembly 22, a lamp circuit board 23 and a ball plunger 24. The lamp housing 21 extends in the front-rear direction. The lamp housing 21 has an upper housing half 211 and a lower housing half 212. The upper housing half 211 is engaged with the lower housing half 212. The upper housing half 211 and the lower housing half 212 together define a rail channel extending in the front-rear direction. The spring assembly 22 and the lamp circuit board 23 are both disposed inside the guide rail channel. The number of the spring assemblies 22 is two and the spring assemblies are arranged at intervals left and right to form a middle passing opening. One of the spring assemblies 22 is electrically connected to the lamp circuit board 23 through a wire. The other spring member 22 is electrically connected to the electrical connector 4 by a wire. The ball plunger 24 is disposed at a front end of the lamp housing 21. The ball plunger 24 extends in the radial direction. The ball plunger 24 has a plunger spring and a plunger steel ball. The plunger spring is arranged at the radial outer end, and the plunger steel ball is arranged at the radial inner end. The lamp holder shell 11 is inserted into the lamp shell 21, and when the lamp holder locking groove is displaced to the plunger steel ball, the plunger steel ball is pushed to the inside of the lamp holder locking groove under the elastic force of the plunger spring, so that the lamp holder shell 11 is locked in the front-back direction. If a large forward force is applied, the plunger steel balls are displaced radially outward and disengaged from the cap locking grooves, the locking of the cap housing 11 is released, and the cap housing 11 can be withdrawn from the lamp housing 21.
The hose part 3 is placed inside the guide rail channel. The hose part 3 is composed of an elongated hose 31, a hose slider 32, a contact assembly 33, a positioning spring 34 and a spring collar 35. The elongated hose 31 extends in the front-rear direction and passes through the intermediate passage opening. The front end of the elongated tube 31 is fixedly connected to the rear end of the base housing 11. Preferably, the front end of the elongated hose 31 has a hose external thread formed thereon. A lamp cap internal thread corresponding to the hose external thread is formed on the rear end portion of the lamp cap housing 11. The front end of the elongated hose 31 is fixedly connected to the rear end of the lamp holder housing 11 by means of the matching of the lamp holder internal thread and the hose external thread. The rear end of the elongated hose 31 is fixedly connected to the hose slider 32. Preferably, the rear end of the elongated hose 31 has a hose external thread formed thereon. The hose slider 32 is formed with a slider internal thread corresponding to the hose external thread. The rear end of the elongated hose 31 is fixedly connected with the hose slider 32 by matching the slider internal thread with the hose external thread. The hose slider 32 is in sliding engagement with the guide track channel. The hose slider 32 is elongated. When the hose slider 32 is in the vertical direction, the transverse width of the hose slider 32 is smaller than that of the middle through opening, and the hose slider 32 can pass through the middle through opening. When the hose slider 32 is in the transverse direction, the transverse width of the hose slider 32 is larger than the middle passing opening, and the hose slider 32 cannot pass through the middle passing opening. The contact assembly 33 is fixed to the rear of the hose slider 32. The number of the contact assemblies 33 is two and the contact assemblies are arranged at intervals left and right. Both of the contact assemblies 33 are electrically connected to the base LED12 by wires.
The positioning spring 34 and the spring retainer 35 surround the outer circumference of the elongated flexible tube 31. The positioning spring 34, the spring retainer 35 and the spring assembly 22 are sequentially arranged from front to back. The front end of the positioning spring 34 is a fixed end. The rear end of the positioning spring 34 is a movable end. When the hose sliding block 32 is displaced to the front side of the spring assembly 22, the positioning spring 34 applies a backward force to the hose sliding block 32 through the spring retainer 35, and the contact assembly 33 abuts against the spring assembly 22, so as to achieve electrical connection between the two.
Through the design of the hose sliding block 32 and the guide rail channel, the long hose 31 can be pulled out, and the irradiation angle can be adjusted and fixed when the lamp is used. When the lamp is not used, the long hose 31 returns to the inside of the guide rail channel, and the space in the cabin is not occupied.
The above description is only intended to illustrate embodiments of the present invention, and the description is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
