Description

Novel lamp holder

Technical Field

The utility model relates to a lighting apparatus field, in particular to novel lamp holder.

Background

The existing lamp bulb has two bases, one is a screw type and the other is a buckle type, the lamp bulb is fixed on a lamp holder through the screw and the buckle, the stability is poor, and particularly under the vibration environment, poor contact and even falling-off are easily caused, so that the lamp bulb is burnt or broken.

This company is for solving above-mentioned problem, specially develops a bulb and lamp shade that mutually support and use, and a metal ring is fixed in the installation on the bulb, sets up the helicitic texture of mutually supporting between metal ring and the lamp shade, fixes the bulb rotation on the lamp shade, has increased the stability and the steadiness of bulb, and the perfect above-mentioned problem of having solved has obtained good effect in the in-service use.

In the subsequent process and product improvement process, the metal skirt of the lamp holder is made of the metal ring and is integrally formed, but because the tail tube of the bulb body and the lamp holder need to be fixed by a sintering process, two defects are found in the process: firstly, because the lamp holder and the bulb body are fixed only by sintering, the sintering position between the bulb body and the lamp holder is easy to break under the conditions of collision and the like, so that the lamp holder and the bulb body are disconnected and separated, and the product quality is influenced; secondly, because the sintering position on the tail tube cannot be too close to the round bulb at the front end of the bulb body, otherwise the round bulb at the front end can be burnt, the sintering position of the tail tube of the bulb and the lamp cap of the metal skirt is at the edge of the skirt, the length of the produced finished bulb is too long, and the practicability and the applicability are greatly reduced, as shown in fig. 5, the tail tube 91 of the old bulb body 9 before the improvement of the company is too long.

In the subsequent improvement process, the company also finds that the bulb body and the base are connected and fixed by plastic parts and glue inside the conventional lamp cap design, so that the bulb body is easy to fall off and poor in temperature resistance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art's defect, provide a novel lamp holder, simple structure, whole material physics mechanical structure connects fixedly, and built-in ceramic member is not only sturdy and durable, and is high temperature resistant moreover, very big improvement the life and the application scope of lamp holder.

The technical scheme of the utility model:

the utility model provides a novel lamp holder contains the metal cup of the fixed bulb body of base and installation, the base comprises ceramic cup and metal dustcoat, the ceramic cup comprises bedplate and external screw thread post, and the metal cup passes through rivet and bedplate connection fixed, be equipped with internal thread and external screw thread on the shirt rim of metal dustcoat, the internal thread of metal dustcoat and the external screw thread phase-match of external screw thread post, the external screw thread of metal dustcoat and the internal thread phase-match of lamp stand, the center department of the bottom of cup of bedplate and metal cup is equipped with the through-hole, the metal cup be equipped with the external screw thread assorted internal thread of bulb body tail pipe.

Furthermore, rivet holes are formed between the seat plate and the bottom of the metal cup, the number of the rivet holes is opposite to that of the rivet holes, and the ceramic cup seat and the metal cup are fixedly connected through the rivet holes.

Further, the number of the rivets is 2-4.

Furthermore, two wire clamping grooves which are opposite in position and different in length are arranged on the seat plate and the cup bottom at the through hole, and a notch is formed in the side wall of the external thread column on one side of each wire clamping groove.

Compared with the prior art, the utility model discloses a set up ceramic cup seat, metal cup, metal dustcoat three part with the lamp holder, and adopt rivet connection fixed between ceramic cup seat and the metal cup, adopt the screw thread to fix between metal cup and the bubble body, adopt the screw thread mode to fix between metal dustcoat and the ceramic cup seat, the mode of pure physical mechanical structure is fixed than traditional glue, it is more firm durable, the ceramic cup seat temperature resistance is good, and the setting of metal cup, ceramic cup seat, metal dustcoat, heat dispersion is good, the life of lamp holder has greatly been improved, also the life of bulb has been improved; the rivet is used for fixing, the firmness is high, the falling is not easy to occur, and the long-time use can still be ensured in a complex use environment; the through hole is provided with a long wire clamping groove and a short wire clamping groove which are used for separating metal polar wires of the lamp wick and are used for separating wires up and down, the lengths are different, the direction and the polarity can be determined conveniently, and the metal wires can be directly connected to the inner side wall of the metal outer cover through the notches, so that the connection and the fixation are convenient; in addition, the metal cup and the tail tube of the bulb body are directly connected by threads, so that the overall length of the bulb is reduced. The utility model discloses simple structure, convenient to use, sturdy and durable, the temperature resistance is good, and heat dispersion is good, and long service life has reduced the length of bulb, very big improvement the application scope of bulb.
