Description

Technical Field

[0001] The utility model relates to the technical field of lamp cups, in particular to a lamp cup with a replaceable lamp cap. Background Art

[0002] Lamp cups have high brightness and energy-saving performance. Therefore, they are now used in more and more places. As the usage rate of lamp cups increases, they are almost replacing traditional lamps. The shell, bulb and lamp holder of traditional lamp cups are all designed in one piece. During use, if a certain part is damaged, the entire lamp has to be replaced, which increases the cost of use for consumers. At present, in order to solve the replacement of individual parts, the shell and lamp holder of existing lamp cups are installed with screws. When replacing the lamp holder and bulb, the shell must be removed first, and then the bulb and lamp holder are disassembled and assembled. Disassembly and assembly are more troublesome, and there is a risk of electric shock and burns when replacing the bulb. Utility Model Content

[0003] In order to overcome the disadvantages that it is troublesome to disassemble and assemble the light bulb and the lamp holder, and there is a risk of electric shock and burns when replacing the light bulb, the technical problem to be solved is: to provide a lamp cup with a replaceable lamp holder.

[0004] The technical solution of the utility model is: a lamp cup with a replaceable lamp cap, comprising a lamp cap, a light bulb is installed on the lamp cap, the light bulb is covered with an outer shell, a sliding sleeve is fixedly connected to the top of the outer shell, a clamping plate is slidably connected to the sliding sleeve through a guide rod, and a knob assembly for driving the clamping plate to move horizontally is arranged on the top of the sliding sleeve.

[0005] In one of the embodiments, the housing is provided with heat dissipation holes which are circumferentially and evenly spaced.

[0006] In one of the embodiments, an L-shaped guide groove is provided on the clamping plate, and the L-shaped guide groove is inclined.

[0007] In one embodiment, the knob assembly includes a rotating sleeve, which is rotatably connected to the top of the sliding sleeve, and a protruding rod is fixedly connected to the bottom of the rotating sleeve, and the protruding rod extends into the L-shaped guide groove of the clamping plate.

[0008] In one embodiment, a rubber strip is further included. The rubber strip is fixed to a side of the clamping plate close to the light bulb, and the rubber strip is in contact with the light bulb.

[0009] In one of the embodiments, a mounting ring is further included. The mounting ring is fixedly connected to the bottom of the shell. A ring shaft is fixedly connected to the mounting ring. A top plate is rotatably connected to the ring shaft. The top plate contacts and cooperates with the bottom of the bulb.

[0010] In one of the embodiments, the bottom of the mounting ring extends inward to limit the top plate.

[0011] The beneficial effects are as follows: 1. After the light bulb is fixed by the provided clamping plate, the lamp holder and the light bulb can be disassembled and assembled by rotating the housing, without manual direct contact with the light bulb and the light holder, which is not only convenient for disassembly and assembly, but also avoids the risk of electric shock and burns;

[0012] 2. Push out the bulb through the top plate, so that it is convenient to take out the bulb for replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0018] Embodiment 1: A lamp cup with a replaceable lamp cap, referring to Figure 1 , Figure 2 and Figure 3 , including a lamp holder 3, on which a bulb 2 is mounted, and a shell 1 is arranged outside the bulb 2, and the shell 1 is provided with heat dissipation holes which are evenly spaced in the circumferential direction, a sliding sleeve 4 is fixedly connected to the top of the shell 1, and three clamping plates 5 are slidably connected in the sliding sleeve 4 through a guide rod, and the three clamping plates 5 are evenly spaced in the circumferential direction, and each clamping plate 5 is provided with an L-shaped guide groove, and each L-shaped guide groove is inclined, and a knob assembly is arranged on the top of the sliding sleeve 4, and the knob assembly is used to drive the clamping plate 5 to move horizontally.

[0019] The knob assembly includes a rotating sleeve 6, which is rotatably connected to the top of the sliding sleeve 4. Three protruding rods 7 are fixedly connected to the bottom of the rotating sleeve 6. The three protruding rods 7 are distributed at equal intervals in the circumferential direction, and each protruding rod 7 extends into the L-shaped guide groove of the corresponding clamping plate 5.

[0020] The device further comprises three rubber strips 8 , which are respectively fixed to the inner sides of adjacent clamping plates 5 , and the three rubber strips 8 are in contact with and cooperate with the light bulb 2 .

[0021] When in use, put the bulb 2 into the shell 1 and rotate the rotating sleeve 6. The rotating sleeve 6 drives the protruding rod 7 to rotate. Since the protruding rod 7 extends into the L-shaped guide groove of the clamping plate 5, and the L-shaped guide groove is inclined, the clamping plate 5 is driven to approach the bulb 2 under the cooperation of the protruding rod 7 and the L-shaped guide groove. The clamping plate 5 drives the rubber strip 8 to contact the bulb 2, thereby fixing the bulb 2. Then, the rotating sleeve 6 is put on the lower part of the lamp holder 3 to make the lamp holder 3 and the bulb 2 dock. At this time, the shell 1 can be rotated to screw the bulb 2 onto the lamp holder 3 to complete the assembly of the lamp cup. Then the rotating sleeve 6 is reversed to drive the clamping plate 5 and the rubber strip 8 to reset through the protruding rod 7. In this way, the lamp holder 3 and the bulb 2 can be disassembled and assembled through the shell 1 without direct manual contact with the bulb 2 and the lamp holder 3. Not only is disassembly and assembly convenient, but also the risk of electric shock and burns is avoided.

[0022] Reference Figure 1 , Figure 2 and Figure 3 , and also includes a mounting ring 9, which is fixed to the bottom of the housing 1, and a ring shaft 10 is fixed to the inner side of the mounting ring 9, and a top plate 11 is rotatably connected to the ring shaft 10, and the top plate 11 contacts and cooperates with the bottom of the bulb 2, and the bottom of the mounting ring 9 extends inward to limit the top plate 11.

[0023] After the bulb 2 is separated from the lamp holder 3, the top plate 11 can be pushed up to push the bulb 2 out of the top plate 11, thereby facilitating the removal of the bulb 2 for replacement.

[0024] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
