Description

Technical Field

[0001] This utility model relates to the field of light bulb processing and application technology, and in particular to a novel anti-residue and easy-to-clean lamp holder glass insulator. Background Technology

[0002] The lamp holder glass insulator is one of the core components of a light bulb. Its main function is to realize the mechanical connection between the lamp holder and the lamp base, and to block current leakage through the insulation structure to ensure electrical safety during the use of the light bulb. At the same time, it provides fixed support for conductive components such as the copper eyepiece to ensure that the current is stably transmitted to the light-emitting element of the light bulb.

[0003] During the processing of traditional lamp holder glass insulators, dust, stains, and other impurities easily remain at the connection points, making cleaning difficult and affecting the insulation performance and service life of the lamp holder. At the same time, there are also shortcomings in the reliability of the connection between the connection part and the lamp holder, and the stability of the connection between the copper eye plate and the glass layer, which can easily lead to problems such as poor contact and detachment, thus restricting the performance and safety of the bulb. Therefore, this utility model proposes a new type of residue-proof and easy-to-clean lamp holder glass insulator. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a new type of anti-residue and easy-to-clean lamp holder glass insulator, so as to solve the problems of traditional lamp holder glass insulators being prone to residual impurities, difficult to clean, and having insufficient connection reliability.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a novel anti-residue and easy-to-clean lamp holder glass insulator is provided, including a lamp holder body, wherein the outer wall of the lamp holder body is provided with a connecting part, and the connecting part is made of stainless iron material, so as to realize a reliable connection and fixation between the entire lamp holder and the external lamp holder. The inner wall of the connecting part is filled with a hollow glass layer near the bottom, and the glass layer extends out of the bottom of the connecting part. The cross-section of the glass layer extending out of the connecting part is arc-shaped, and this part occupies 3 / 4 of the bottom of the connecting part to achieve insulation and sealing of the end face of the connecting part. A copper eyepiece is fixedly connected at the bottom center of the glass layer to enable the entire bulb's circuit to be connected and to transmit current.

[0006] The present invention is further configured such that: the outer wall of the connecting part is provided with a threaded groove A, and the spacing of the threaded groove A is 0.792mm, and an air hole A is provided through the outer wall of the threaded groove A near the middle position.

[0007] Through the above technical solution, the specific spacing design of the thread groove A not only ensures the thread engagement accuracy with the external lamp holder and improves the connection stability, but also reduces the space for impurities to remain in the thread groove; the through-hole A can realize the airflow inside and outside the connection part, avoid the impurities from being adsorbed on the surface of the connection part due to the air pressure difference caused by temperature changes, and at the same time, during cleaning, the airflow can carry the cleaning medium deep into the thread groove, which is convenient for impurities to fall off, and achieves the effect of preventing residue and easy cleaning.

[0008] The present invention is further configured such that: the copper eyepiece is composed of a horizontal ring and an anti-detachment protrusion, and the anti-detachment protrusion extends into the interior of the glass layer in a trumpet shape.

[0009] Through the above technical solution, the horn-shaped anti-detachment protrusion increases the contact area and mechanical interlocking force between the copper eyelet and the glass layer. By utilizing the radial expansion force of the horn-shaped structure, the copper eyelet is firmly embedded in the glass layer, effectively preventing the copper eyelet from falling off due to vibration, current impact and other factors during use, and ensuring the stability and reliability of circuit connection.

[0010] The present invention is further configured such that: a threaded groove B is provided on the outer wall of the connecting part, and the spacing of the threaded groove B is 0.897mm, and an air hole B is provided through the outer wall of the threaded groove B near the middle position.

[0011] Through the above technical solution, the spacing design of the thread groove B is differentiated and adapted to the thread groove A, which can meet the installation requirements of different specifications of lamp holders and expand the product's application range. The air hole B works with the thread groove B to reduce impurity residue through airflow. On the other hand, during the thread connection process, the air hole B can discharge air and impurities at the thread meshing point, avoiding the connection tightness being affected by air blockage or impurity jamming. At the same time, it is convenient to rinse and remove impurities during cleaning.

[0012] The present invention is further configured such that: the copper eyepiece is composed of a horizontal ring and an anti-detachment protrusion, and the anti-detachment protrusion is bent near the end face and extends into the interior of the glass layer.

[0013] Through the above technical solution, the bending design of the anti-detachment protrusion forms a hook-shaped structure. After being embedded in the glass layer, the bent part forms a mechanical limit with the glass layer. Compared with the straight rod structure, it greatly improves the connection strength between the copper eye and the glass layer, effectively resists axial tensile force and radial shear force, prevents the copper eye from separating from the glass layer, and ensures the continuity of current transmission.

[0014] The present invention is further configured such that: a locking block is symmetrically and fixedly connected to the outer arc wall of the connecting part near the bottom position, and the locking block is cylindrical.

[0015] Through the above technical solution, the cylindrical locking blocks are symmetrically distributed and can form a precise engagement with the slots on the lamp holder, realizing rapid positioning and installation, enhancing the connection stability between the connecting part and the lamp holder, and preventing the lamp head from rotating or falling off during use.

[0016] The present invention is further configured such that: the copper eyepiece is composed of a horizontal ring and an anti-detachment protrusion, and the anti-detachment protrusion is arranged in a trumpet shape and extends into the interior of the glass layer.

[0017] Through the above technical solution, the trumpet-shaped anti-detachment protrusion forms an outwardly expanding support structure inside the glass layer. This not only increases the contact area with the glass layer, but also utilizes the enveloping force of the glass layer and the expansion force of the anti-detachment protrusion to interact, making the copper eye piece tightly bonded to the glass layer and avoiding loose gaps. This ensures the stability of the circuit connection and prevents impurities from entering the interior through gaps, thereby improving insulation performance and anti-residue effect.

[0018] The beneficial effects of this utility model are as follows: 1. The novel anti-residue and easy-to-clean lamp holder glass insulator proposed in this utility model is designed with an arc-shaped structure for the part of the glass layer extending out of the connection part, which occupies 3 / 4 of the bottom of the connection part. The arc-shaped surface is smooth and without dead corners, reducing the space for impurities to adhere, while facilitating the flow of cleaning medium, thus achieving the effect of anti-residue and easy cleaning. The connection part is made of stainless iron material, which has both rust resistance and structural strength, ensuring the reliability and service life of the connection with the lamp holder. 2. The novel anti-residue and easy-to-clean lamp holder glass insulator proposed in this utility model adopts a variety of threaded groove designs and snap-fit ​​block structures to adapt to the installation requirements of lamp holders of different specifications, thereby improving the versatility of the product; the anti-detachment protrusion of the copper eye piece adopts a trumpet-shaped or bent design, which enhances the connection stability with the glass layer, avoids poor contact or detachment problems, and ensures the safety of the bulb and the stability of circuit conduction.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figures 1-5 As shown, a novel anti-residue and easy-to-clean lamp holder glass insulator includes a lamp holder body 1, and a connecting part 2 is provided on the outer wall of the lamp holder body 1. The connecting part 2 is made of stainless iron material to reliably connect and fix the entire lamp holder to the external lamp holder. The inner wall of the connecting part 2 is filled with a hollow glass layer 3 near the bottom, and the glass layer 3 extends out of the bottom of the connecting part 2. The cross-section of the glass layer 3 extending out of the connecting part 2 is arc-shaped, and this part occupies 3 / 4 of the bottom of the connecting part 2 to achieve insulation and sealing of the end face of the connecting part 2. A copper eyelet 4 is fixedly connected at the bottom center of the glass layer 3 to enable the entire bulb circuit to be connected and to transmit current.

[0023] Example 1: like Figure 4 As shown, the outer wall of the connecting part 2 is provided with threaded grooves A21, and the spacing of the threaded grooves A21 is 0.792mm. An air hole A211 is provided through the outer wall of the threaded grooves A21 near the middle. The specific spacing design of the threaded grooves A21 ensures the thread engagement accuracy with the external lamp holder and improves the connection stability, while also reducing the space for impurities to remain in the threaded grooves. The through-hole A211 allows airflow to pass through the connecting part 2, preventing impurities from being adsorbed on the surface of the connecting part due to pressure differences caused by temperature changes. At the same time, during cleaning, the airflow can carry the cleaning medium deep into the threaded grooves, making it easier for impurities to fall off, achieving the effect of preventing residue and easy cleaning. The copper eyelet 4 consists of a horizontal ring and an anti-detachment protrusion. The anti-detachment protrusion extends into the interior of the glass layer 3 in a trumpet shape. The trumpet-shaped anti-detachment protrusion increases the contact area and mechanical interlocking force between the copper eyelet 4 and the glass layer 3. By utilizing the radial expansion force of the trumpet-shaped structure, the copper eyelet 4 is firmly embedded in the interior of the glass layer 3, effectively preventing the copper eyelet 4 from falling off due to factors such as vibration and current impact during use, and ensuring the stability and reliability of the circuit connection.

[0024] Example 2: like Figure 5As shown, the outer wall of the connecting part 2 is provided with a threaded groove B22, and the spacing of the threaded groove B22 is 0.897mm. An air hole B221 is provided through the outer wall of the threaded groove B21 near the middle. The spacing design of the threaded groove B22 is different from that of the threaded groove A21 to meet the installation requirements of different specifications of lamp holders and expand the application range of the product. The air hole B221 cooperates with the threaded groove B22. On the one hand, it reduces the residue of impurities through airflow. On the other hand, during the threaded connection process, the air hole B221 can discharge air and impurities at the thread meshing point, avoiding the connection tightness affected by air blockage or impurity jamming. At the same time, it is convenient to rinse and remove impurities during cleaning. The copper eyelet 4 consists of a horizontal ring and an anti-detachment protrusion. The anti-detachment protrusion is bent near the end face and extends into the interior of the glass layer 3. The bent design of the anti-detachment protrusion forms a hook-like structure. After being embedded in the glass layer 3, the bent part forms a mechanical limit with the glass layer 3. Compared with a straight rod structure, this greatly improves the connection strength between the copper eyelet 4 and the glass layer 3, effectively resisting axial tensile force and radial shear force, preventing the copper eyelet 4 from separating from the glass layer 3, and ensuring the continuity of current transmission.

[0025] Example 3: like Figures 1-3 As shown, a locking block 23 is symmetrically fixedly connected to the outer arc wall of the connecting part 2 near the bottom position, and the locking block 23 is cylindrical. The cylindrical locking blocks 23 are symmetrically distributed and can form a precise engagement with the slot on the lamp holder, realizing quick positioning and installation, enhancing the connection stability between the connecting part 2 and the lamp holder, and preventing the lamp head from rotating or falling off during use. The copper eyelet 4 consists of a horizontal ring and an anti-detachment protrusion, which is funnel-shaped and extends into the interior of the glass layer 3. The funnel-shaped anti-detachment protrusion forms an outwardly expanding support structure inside the glass layer 3, which not only increases the contact area with the glass layer 3, but also utilizes the wrapping force of the glass layer 3 and the expansion force of the anti-detachment protrusion to interact, so that the copper eyelet 4 and the glass layer 3 are tightly bonded, avoiding loose gaps. This ensures the stability of the circuit connection and prevents impurities from entering the interior through gaps, thereby improving insulation performance and anti-residue effect.
