Abstract
Description
- The disclosure relates to a lamp holder, more particularly to a waterproof lamp holder.
- A conventional waterproof lamp is generally equipped with washers or seal tapes to block or fill gaps or holes in a housing thereof, thereby achieving the goal of waterproofing.
- However, for a conventional lamp including a frame and a lamp seat that is rotatably mounted in the frame, since the shape of a gap between the frame and the lamp seat changes continuously during the rotation of the lamp seat relative to the frame, the abovementioned washers and seal tapes cannot be utilized to fulfill the waterproofing function.
- Therefore, the object of the disclosure is to provide a rotatable and waterproof lamp holder.
- According to the disclosure, a lamp holder is adapted to be mounted with a lamp, and includes a frame seat, a rotatable seat, and a lens unit. The frame seat includes a barrel wall that surrounds a first axis, that defines a rotating space, and that has opposite lighting end and installing end along the first axis. The rotatable seat is disposed in the rotating space, and has an inner surface that surrounds the first axis and that defines a mounting space adapted for receiving the lamp, an outer surrounding surface that is opposite to the inner surface, a connecting end that cooperates with the installing end of the barrel wall to define a gap therebetween, and two rotating studs that are spaced apart from each other along a second axis perpendicular to the first axis, and that extend from the outer surrounding surface to barrel wall such that the rotatable seat is rotatable about the second axis relative to the frame seat. The lens unit is disposed in the rotating space and is in watertight connection with the rotatable seat. The lamp holder further includes a watertight elastic unit made of an elastic material, and interconnecting the installing end of the barrel wall of the frame seat and the connecting end of the rotatable seat to completely block the gap.

In this embodiment, thesprings 16 are torsion springs and are adapted to cooperate with therimwall 14 to clamp thewall segments 91 of thewall structure 9 thereamong when the lamp holder is disposed in themounting slot 92 so as to abut therim wall 14 tightly against thewall segments 91 and to fasten the lamp holder on thewall structure 9. - Further referring to
Figs. 3 to 5 , therotatable seat 2 is disposed in the rotatingspace 111 of thebarrel wall 11, and includes arotatable seat member 21, amounting seat member 22, and a watertight member washer 24. - In this embodiment, the
rotatable seat member 21 has an outer surroundingsurface 211, an inner surroundingsurface 212 opposite to the outer surroundingsurface 211, twostop parts 213 protruding from the inner surroundingsurface 212, a connectingend 216 cooperating with the installingend 13 of thebarrel wall 11 to define a gap 217 (seeFig. 4 ) therebetween, and acoupling part 214 formed in an end of the inner surroundingsurface 212 that is opposite to the connectingend 216 along the first axis (L1).

Thetrack portion 229 of each of theengaging parts 226 has aninclined edge 231 and anon-inclined edge 232 that are respectively proximate to and distal from theopening portion 228 along the first axis (L1), such that awidth 233 between theinclined edge 231 and thenon-inclined edge 232 gradually increases from thelimit portion 230 to theopening 228, and gradually decreases from theopening 228 to thelimit portion 230. - Referring further to

watertight member washer 24 is clamped between thecoupling part 214 of therotatable seat member 21 and therib part 227 of themounting seat member 22. - Referring back to
Figs. 1 to 4 , thelens unit 3 is disposed in the rotatingspace 111, and in watertight connection with therotatable seat 2. Specifically, thelens unit 3 includes alens 31 disposed in themounting space 222 and engaging themounting groove 223, and awatertight lens washer 32 disposed in themounting space 222 and clamped between thelens 31 and thesupport wall 224 of therotatable seat 2. Thelens unit 3 further includes acirclip 33 disposed in themounting groove 223 and at a side of thelens 31 opposite to thewatertight lens washer 32 along the first axis (L1). The watertight lens washer 32, thelens 31, and thecirclip 33 are arranged along the first axis (L1). - The watertight
elastic unit 4 is made of an elastic material, interconnects the installingend 13 of thebarrel wall 11 of theframe seat 1 and the connectingend 216 of therotatable seat member 21 to completely block thegap 217, and includes anelastic member 41, afirst fastening ring 42, and asecond fastening ring 43. - The
elastic member 41 has anouter rim 411 connected to the installingend 13 of thebarrel wall 11, aninner rim 412 connected to the connectingend 216 of therotatable seat member 21, and a connectingportion 413 interconnecting the outer andinner rims gap 217. - The connecting
portion 413 has an inverted U-shaped cross-section when therotatable seat 2 is at the normal state, and includes two largeelastic segments 414 that are spaced apart from each other along a third axis (L3) (seeFig. 4 ) perpendicular to the first and second axes (L1, L2), and two smallelastic segments 415 that are arranged alternately with the largeelastic segments 414. Each of the largeelastic segments 414 has twoend sections 416 that are circumferentially spaced apart from each other, and anintermediate section 417 that is disposed between theend sections 416 and that has a height along the first axis (L1) not smaller than that of theend sections 416. Each of the smallelastic segments 415 interconnects a respective one of theend sections 416 of one of the largeelastic segments 414 and a respective one of theend sections 416 of the other one of the largeelastic segments 414, and has amiddle section 418 disposed between the respective one of theend sections 416 of one of the largeelastic segments 414 and the respective one of theend sections 416 of the other one of the largeelastic segments 414. A height of each of the smallelastic segments 415 gradually decreases from opposite circumferential ends thereof toward themiddle section 418 thereof. - The
first fastening ring 42 is secured fixedly to theouter rim 411 and is fastened threadedly to the installingend 13 of thebarrel wall 11. Thesecond fastening ring 43 is secured fixedly to theinner rim 412 and is fastened threadedly to the connectingend 216 of therotatable seat member 21. - As shown in
Figs. 1 and2 , theclip member 5 has afastening end portion 51 that is fastened fixedly on the connectingend 216 of therotatable seat member 21, and afree end portion 52 that is opposite to thefastening end portion 51 and that is formed with aretaining groove 53 adapted to be engaged with thelamp 8. - Therefore, by virtue of the rotation of the
rotatable seat 2 between the normal state and the rotated state, a light direction of thelamp 8 can be adjusted. Moreover, with the presence of the watertightelastic unit 4, thegap 217 can be properly blocked during the rotation of therotatable seat 2 even with the shape of thegap 217 changing continuously. - Moreover, as shown in
Fig. 4 , by virtue of thewatertight member washer 24 that is clamped between therotatable seat member 21 and themounting seat member 22, and thewatertight lens washer 32 and thecirclip 33 that are disposed in themounting groove 223 of themounting seat member 22, water can be blocked from entering the lamp holder from an end opposite to the watertightelastic unit 4. - Furthermore, as shown in
Fig. 2 , thewatertight seat washer 15 serves to prevent passage of the water through a gap between theframe seat 1 and thewall structure 9.
