Description

Technical fields:

[0001] This utility model relates to the field of lamp holder technology, and specifically to an improved push-handle switch lamp holder. Background technology:

[0002] A lamp holder is the connector for a light bulb. A light bulb must be mounted in a lamp holder for support and power supply. The lamp holder is an essential component used with a light bulb. Common lamp holders can be categorized into four types based on their switching operation: switchless lamp holders (with a separate switch on the power cord), rotary switch lamp holders, zipper switch lamp holders, and push-handle switch lamp holders.

[0003] Among them, the push-handle switch lamp holder is simple and intuitive to operate. The circuit can be turned on and off simply by pressing or pushing the push handle. It is very convenient to use and is widely popular, especially suitable for occasions that require frequent switching.

[0004] Currently, there are many push-handle type lamp holders on the market. For example, Chinese utility model patent application CN202434859U discloses a push-handle type lamp holder, which includes: a cylindrical shell, an insulating sheet, an insulating base, a push handle, and a lower conductive sheet. The top surface of the insulating base has a horizontally penetrating groove, and the push handle is installed in the groove and can reciprocate along it, thereby pushing the lower conductive sheet to swing, thus controlling the current flow between it and an upper conductive sheet, thereby controlling the illumination of the light-emitting element. The insulating base has two hooks on its outside for securing the power cord by winding it through the hooks during wiring, eliminating the need for UL knots. This technical solution offers convenient and quick wiring, reduces components and size, eliminates the need for UL knots, and easily controls the illumination of the light-emitting element.

[0005] However, this existing structure still has the following shortcomings:

[0006] In this technical solution, the lower conductive sheet of the lamp holder is designed like a rocker arm. A protruding pusher pushes the lower conductive sheet against its adjacent end, causing it to swing around the top edge of the receiving groove. This allows the lower conductive sheet to contact the upper conductive sheet, achieving contact conductivity. However, this method relies solely on the pusher for contact, lacking elasticity. Poor contact is easily caused by insufficient contact between the pusher protrusion and the lower conductive sheet, or by foreign matter adhering to the lower conductive sheet. Stability and reliability need improvement, and instability is more likely to occur during frequent switching. Furthermore, the contact between the upper conductive sheet and the positive conductive sheet is also contact-dependent. This contact is prone to failure due to insufficient contact, minor deformation of the sheets, etc., and is easily damaged over time. The conductive sheets should be designed as a single unit.

[0007] In view of the above, the inventors propose the following technical solution. Utility model content:

[0030] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0031] See Figures 1 to 10 As shown, this is an improved push-handle switch lamp holder. In one embodiment of this utility model, it includes: a base 1, in which an integrally formed first conductive sheet 11, an integrally formed second conductive sheet 12, and an integrally formed third conductive sheet 13 are disposed, and a groove 14 is formed between the first conductive sheet 11 and the second conductive sheet 12 in the base 1; a cover 2, which covers the base 1, and the cover 2 has a connecting hole 21 for the first conductive sheet 11 to pass through and be embedded; and a nozzle 3, which is fixed to the cover 2 and used to install an external lamp body; and a push-handle switch. The handle 4 is installed in the slide groove 14 in a reciprocating manner. In this embodiment, the first conductive sheet 11, the second conductive sheet 12 and the third conductive sheet 13 are all integrally formed. The second conductive sheet 12 and the third conductive sheet 13 are respectively installed in the first mounting groove 15 and the second mounting groove 16 on the base body 1. The lower end of the first conductive sheet 11 is installed in the first mounting groove 15, and the upper end of the first conductive sheet 11 passes through the connecting hole 21 and extends upward into the inlet cylinder 3. The cover body 2 is also provided with an insulating part 22 for separating the first conductive sheet 11 and the third conductive sheet 13.

[0032] The push handle 4 is provided with a swingable guide plate 5 for making the first conductive plate 11 and the second conductive plate 12 conductively connected. When the push handle 4 is pushed, the swing guide plate 5 is driven to swing and make elastic contact with the first conductive plate 11 and the second conductive plate 12 to achieve electrical connection.

[0033] In this embodiment, an integrally molded first conductive sheet 11, second conductive sheet 12, and third conductive contact sheet 13 are used. Without affecting production, this enhances conductivity stability and reliability, and also improves assembly convenience, making assembly easier and more convenient. Furthermore, unlike existing structures, this invention does not use an up-and-down rocker structure. Instead, the first conductive sheet 11 and the second conductive sheet 12 are respectively arranged on both sides of the slide groove 14. A swinging conductive contact sheet 5 is provided on the push handle 4. Pushing the push handle 4 causes the swinging conductive contact sheet 5 to swing, thereby making elastic contact with the first conductive sheet 11 and the second conductive sheet 12 to achieve conductivity. This structure effectively improves the stability and reliability of conductivity, allowing for precise and stable control even when frequent switching is required. It is suitable for long-term use, has a long service life, and has minimal impact on existing installation methods and assembly processes. It is applicable to most push-handle lamp holders and has significant market competitiveness.

[0034] The first conductive sheet 11 has an integrally formed first protruding portion 110 for elastic contact with the swinging conductive sheet 5; the second conductive sheet 12 has an integrally formed second protruding portion 120 for elastic contact with the swinging conductive sheet 5. In this embodiment, specifically, from a top view, the first protruding portion 110 and the second protruding portion 120 are distributed in a figure-eight shape, and the distance between the first protruding portion 110 and the second protruding portion 120 is smaller than the size of the swinging conductive sheet 5. This allows the swinging conductive sheet 5 to easily and elastically contact the first protruding portion 110 and the second protruding portion 120 when it swings in the direction of the first protruding portion 110 and the second protruding portion 120. Furthermore, the more the swinging conductive sheet 5 swings, the tighter the contact, which greatly improves the stability and reliability of the conduction.

[0035] The inner walls on both sides of the slide groove 14 are respectively provided with a first swing groove 141 and a second swing groove 142. The first swing groove 141 and the second swing groove 142 are both V-shaped. The swing guide piece 5 is installed in the first swing groove 141 and the second swing groove 142 from top to bottom, and the fixed end 51 of the swing guide piece 5 is fixedly snapped into the bottom of the first swing groove 141 and the second swing groove 142. The swing end 52 of the swing guide piece 5 can swing along the first swing groove 141 and the second swing groove 142.

[0036] See Figure 3 and Figure 6As shown, the swing guide plate 5 includes a fixed end 51 and a swing end 52 integrally formed with the fixed end 51. The push handle 4 has a concave shape in the middle. The swing guide plate 5 is C-shaped and located in the middle of the push handle 4. A spring 6 is provided to separate the swing end 52 of the swing guide plate 5 from the push handle 4. The swing guide plate 5 also has protruding ribs 58 for increasing strength. The push handle 4 also has protruding locking points 401 for positioning the spring 6. Correspondingly, the swing end 52 has a protruding part 521 protruding downward. In this embodiment, the push handle 4 has a first pushing part 41 and a second pushing part 42 protruding at both ends for pressing by the human hand. Here, when the first abutment part 41 of the push handle 4 is manually pressed, the push handle 4 slides in the slide groove 14. The locking point 401 on the push handle 4 drives the lower end of the spring 6 to move, thereby tilting the spring 6 and generating a force to push the swing end 52 of the swing guide plate 5, causing the swing end 52 to swing towards the first abutment part 41. It is limited by the first swing groove 141 and the second swing groove 142, so that it does not swing excessively or not swing in place. Furthermore, the swing end 52 makes elastic contact with the first lifting part 110 and the second lifting part 120 to form a conduction. When the second abutment part 42 of the push handle 4 is manually pressed, the same process is repeated, causing the swing end 52 to swing towards the second abutment part 42 and disengage from the first lifting part 110 and the second lifting part 120 to disconnect the conduction. In addition, combined with Figure 6 As shown, the protruding ribs 58 on the swing guide plate 5 can effectively enhance the strength of the swing guide plate 5 and prevent the swing guide plate 5 from undergoing unexpected deformation during swinging due to insufficient rigidity, thereby effectively improving the service life of the swing guide plate 5.

[0037] The base 1 has a first mounting groove 15 and a second mounting groove 16 on both sides of the sliding groove 14, and the second conductive piece 12 and the third conductive piece 13 are respectively installed in the first mounting groove 15 and the second mounting groove 16. The base 1 has a first extension groove 17 for accommodating the first tilting part 110, and the first extension groove 17 is connected to the first swing groove 141. The base 1 also has a second extension groove 18 for accommodating the second tilting part 120, and the second extension groove 18 is connected to the second swing groove 142. Here, the first tilting part 110 and the second tilting part 120 are respectively accommodated in the first extension groove 17 and the second extension groove 18 so that the swinging conductive piece 5 can make elastic contact with the first tilting part 110 and the second tilting part 120.

[0038] See Figure 2As shown, the base 1 has a first riveting hole 101 and a second riveting hole 102. The cover 2 has a third riveting hole 203 and a fourth riveting hole 204, which correspond to the first riveting hole 101 and the second riveting hole 102, respectively. The nozzle 3 has a fifth riveting hole 305 and a sixth riveting hole 306, which correspond to the third riveting hole 203 and the fourth riveting hole 204, respectively. A first rivet 103 and a second rivet 104 are also inserted into the base 1. The first rivet 103 passes through the first riveting hole 101, the third riveting hole 203, and the fifth riveting hole 305 in sequence to rivet the lamp holder. The second rivet 104 passes through the second riveting hole 102, the fourth riveting hole 204, and the sixth riveting hole 306 in sequence to rivet the lamp holder.

[0039] The base 1 has a protruding wiring portion 1011 at the upper opening of the first riveting hole 101, and the wiring portion 1011 extends into the third riveting hole 203. The third guide piece 13 has a wire clamping end 131, which is bent and fitted onto the wiring portion 1011 and sleeved onto the second rivet 104. Here, since the third guide piece 13 needs to communicate with the mouthpiece 3, it is connected to it through the second rivet 104 to achieve communication with the mouthpiece 3.

[0040] Combination Figure 2 , Figure 9 and Figure 10 As shown, the second conductive sheet 12 is formed with at least one second limiting part 92 for engaging and limiting with the first mounting groove 15, and the third conductive sheet 13 is formed with at least one third limiting part 93 for engaging and limiting with the second mounting groove 16. Here, to ensure the stability and prevent shifting of the second conductive piece 12 and the third conductive piece 13 during lamp holder installation, a second limiting part 92 and a third limiting part 93 are formed on the second conductive piece 12 and the third conductive piece 13, respectively. When the second conductive piece 12 is inserted into the first mounting groove 15, the second limiting part 92 abuts against the inner wall of the first mounting groove 15, generating a force that confines the second conductive piece 12 within the first mounting groove 15, preventing it from easily lifting. It can only be moved by vertically pulling upwards with a certain force. This ensures that the second conductive piece 12 will not shift or lift during subsequent installation of the push handle 4 (the same applies to the third conductive piece 13). The cover 2 can be installed smoothly without manual secondary pressing, effectively reducing a step and improving efficiency. Preferably, both the second limiting part 92 and the third limiting part 93 are barbed pieces with a tear-shaped design.

[0041] In the second embodiment of this utility model, see Figure 8As shown, the lower end face of the base 1 has a first cable routing hole 105 communicating with the first mounting groove 15 and used for connecting an external power cord. The lower end face of the base 1 also has a second cable routing hole 106 communicating with the second mounting groove 16 and used for connecting an external power cord. The base 1 has a first hook portion 107 and a second hook portion 108 protruding from it for positioning the external power cord. Compared with Embodiment 1, Embodiment 2 differs only in the above-mentioned parts; the rest are the same and will not be described in detail here.

[0042] In summary, this utility model employs an integrally formed first conductive sheet 11, second conductive sheet 12, and third conductive sheet 13, which enhances conductivity stability and reliability without affecting production, and also improves assembly convenience, making assembly easier and more convenient.

[0043] Meanwhile, unlike existing structures, this utility model does not use an up-and-down rocker structure. Instead, a first conductive plate 11 and a second conductive plate 12 are respectively set on both sides of the slide groove 14. By setting a swing guide plate 5 on the push handle 4, pushing the push handle 4 can make the swing guide plate 5 swing, thereby making elastic contact with the first conductive plate 11 and the second conductive plate 12 to achieve conduction. This structure can effectively improve the stability and reliability of conduction. Even when frequent switching is required, it can accurately and stably control the conduction. It is suitable for long-term use and has a long service life. Moreover, this technical solution has little impact on the original installation method and assembly process. It is applicable to most push handle lamp holders and has great market competitiveness.

[0044] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
