Description

Technical Field

[0001] The present application relates to the technical field of LED lamp holder design, and in particular to an anti-electric shock lamp holder for an LED bulb. Background Art

[0002] Most of the existing LED bulbs are screw-in bulbs, which feature a screw thread metal as one of the electrodes. This requires that the electrode that contacts the thread on the socket should be connected to the neutral wire during installation, and the electrode that contacts the round contact in the middle of the bulb should be connected to the live wire. The advantage is that the socket can be firmly fixed through the threaded connection, and the precision requirements for the bulb and socket processing are lower than those for the bayonet bulb. However, due to the exposed thread, there is a certain risk of electric shock.

[0003] Before the operator replaces the LED bulb, the operator needs to turn off the switch to cut off the power supply to ensure the operator's safety. However, in the process of replacing the bulb, if someone accidentally turns on the switch, the live wire in the lamp holder is connected, and the live wire contact connects with the contact at the bottom of the bulb to supply power to the bulb. At this time, the bulb is still in the operator's hand, which is easy to cause electric shock accidents. Summary of the invention

[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0005] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide an anti-shock lamp holder for an LED bulb, comprising: a base, forming an installation cavity; a longitudinal moving part, placed in the upper part of the installation cavity, and moving longitudinally relative to the installation cavity, the longitudinal moving part forming an internal thread, and the lower end of the longitudinal moving part forming a downward first resistance part; a transverse moving part, the upper surface of which forms a contact and a second resistance part, the contact is located directly below the longitudinal moving part in the installation cavity, the first resistance part and the second resistance part form a transmission connection, and when the longitudinal moving part moves downward, the transverse moving part moves laterally to disengage the contact from directly below the longitudinal moving part; an elastic part, which resets the transverse moving part until the contact is directly below the longitudinal moving part.

[0006] Furthermore, a protective ring is arranged around the contact point, and the protective ring forms a clearance groove opposite to the lateral movement direction of the traverse member.

[0007] Furthermore, the longitudinal moving member includes an insulating sleeve and a metal sleeve, the metal sleeve forms the internal thread, the metal sleeve is sleeved and fixed on the inner wall of the insulating sleeve, the outer wall of the insulating sleeve is slidably connected to the base, and the lower end of the insulating sleeve forms the first abutment portion.

[0008] Furthermore, the transverse moving member includes an insulating bottom plate and a metal block, wherein the metal block is fixed to the upper surface of the insulating bottom plate, the contact is formed on the metal block, and the insulating bottom plate is slidably connected to the base.

[0009] Furthermore, a slide groove is formed on the lower surface of the installation cavity, the length direction of the slide groove coincides with the lateral movement direction of the transverse moving member, and the insulating bottom plate is slidably connected to the slide groove.

[0010] Further, the first abutment portion is a downward wedge-shaped structure, the inclined surface of the first abutment portion faces the direction of lateral movement of the transverse member, and the second abutment portion is an upward right-angled trapezoidal structure, the inclined surface of the second abutment portion is slidably connected to the inclined surface of the first abutment portion.

[0012] Furthermore, a plurality of fixing holes are formed on the base.

[0013] Furthermore, an annular baffle is provided at the upper end of the base, the annular baffle abuts against the upper end of the longitudinal moving member, and the annular baffle is threadedly connected to the upper end of the base.

[0014] The beneficial effects of this application are:

[0015] The contact is connected to the live wire, and the internal thread is connected to the neutral wire. When the operator installs the LED bulb, he puts the bulb against the longitudinal moving part, and rotates the bulb so that the screw mouth engages with the internal thread on the longitudinal moving part. At this time, the longitudinal moving part moves downward, and through the transmission connection of the first contact part and the second contact part, the transverse moving part moves horizontally to make the contact disengage from the bottom of the longitudinal moving part. After the screw mouth and the internal thread are completely tightened, the operator lets go to release the pressure on the bulb, and the elastic part resets the transverse moving part until the contact is located directly below the longitudinal moving part. At this time, the contact is connected to the bulb, and current passes through the bulb. During the installation of the bulb, even if someone accidentally closes the switch, the contact is far away from the bottom of the longitudinal moving part, avoiding accidents of electric shock to the operator caused by the bulb being powered on.

[0031] Reference Figure 1-5 ,

[0032] A shock-proof lamp holder for an LED bulb comprises: a base 1, a longitudinal moving member 2, a transverse moving member 3 and an elastic member 4. An installation cavity for installing the longitudinal moving member 2, the transverse moving member 3 and the elastic member 4 is formed in the base 1. The longitudinal moving member 2 contacts the upper part of the installation cavity and can move longitudinally relative to the installation cavity. An internal thread matching the screw thread of the LED bulb is formed in the longitudinal moving member 2, and the internal thread is externally connected to the neutral wire. A first abutment portion 5 extending downward is formed at the lower end of the longitudinal moving member 2, and a second abutment portion 6 is slidably connected to the first abutment portion 5 on the upper surface of the transverse moving member 3. A contact for an external live wire is also formed on the upper surface of the transverse moving member 3 for abutting against the bottom end of the bulb. When the bulb is not installed or is installed, the contact is located directly below the internal thread of the longitudinal moving member 2, and the first abutment 5 and the second abutment 6 form a transmission connection. When the worker installs the bulb, the longitudinal moving member 2 is pressed by the bulb, so that the longitudinal moving member 2 moves downward and drives the transverse moving member 3 to move laterally, so that the contact is separated from the bottom of the longitudinal moving member 2 to ensure that the contact will not connect to the bulb and generate current in the bulb. The elastic member 4 resets the transverse moving member 3 to the position where the contact is located directly below the longitudinal moving member 2. That is, after the installation is completed, the worker releases the pressure on the bulb, and the elastic member 4 pushes the transverse moving member 3 to move in the direction opposite to the transverse movement direction, so that the contact is connected to the bottom end of the bulb. During the resetting process of the transverse moving member 3, the longitudinal moving member 2 moves upward and resets because the first abutment 5 and the second abutment 6 form a transmission connection.

[0033] Specifically, a protective ring 7 is arranged around the contact, and the protective ring 7 is made of plastic material to prevent the contact from short-circuiting with surrounding parts. The protective ring 7 forms a clearance groove 8 opposite to the lateral movement direction of the traverse member 3. The shape of the clearance groove 8 matches the bottom end of the bulb. When the traverse member 3 is reset, the bottom end of the bulb passes through the clearance groove 8 and finally contacts the contact.

[0034] Specifically, the longitudinal moving member 2 includes an insulating sleeve 9 and a metal sleeve 10. The insulating sleeve 9 is made of plastic, the metal sleeve 10 is made of stainless steel, and the metal sleeve 10 is externally connected to the neutral line. The metal sleeve 10 forms an internal thread that engages with the screw of the bulb. The metal sleeve 10 is sleeved and fixed on the inner wall of the insulating sleeve 9 by glue. The outer wall of the insulating sleeve 9 forms a longitudinal sliding connection with the base 1, and the lower end of the insulating sleeve 9 forms a first contact portion 5. The metal sleeve 10 is connected to the base 1 through the insulating sleeve 9 to prevent the metal sleeve 10 from leaking electricity when the bulb is powered on, causing an accident.

[0035] Specifically, the traverse member 3 includes an insulating bottom plate 11 and a metal block 12. The insulating bottom plate 11 is made of plastic, and the metal block 12 is made of stainless steel. The metal block 12 is glued and fixed to the upper surface of the insulating bottom plate 11. The external live wire passes through the insulating bottom plate 11 and communicates with the metal block 12. A contact is formed on the metal block 12, and the insulating bottom plate 11 is slidably connected to the base 1 to prevent the contact from being directly connected to the base 1 and causing leakage.

[0036] Specifically, a slide groove 13 is formed on the lower surface of the installation cavity, the length direction of the slide groove 13 coincides with the direction of the lateral movement of the transverse moving member 3, the insulating bottom plate 11 is slidably connected with the slide groove 13, and the slide groove 13 guides the lateral movement of the transverse moving member 3, making the movement of the transverse moving member 3 smoother, thereby preventing the transverse moving member 3 from being blocked directly below the longitudinal moving member 2 during the installation of the bulb, causing the contact to directly contact the bottom end of the bulb, which may cause leakage.

[0037] Specifically, the first abutment 5 is a downward wedge-shaped structure, and the inclined surface of the first abutment 5 faces the direction of the lateral movement of the transverse moving member 3. The second abutment 6 is an upward right-angled trapezoidal structure, and the inclined surface of the second abutment 6 is slidably connected to the inclined surface of the first abutment 5. When the insulating sleeve 9 is moved downward by the pressure of the operator, the second abutment 6 and the first abutment 5 slide and rub, and at the same time, the first abutment 5 generates a lateral thrust on the second abutment 6 to make the second abutment 6 move laterally away from directly below the longitudinal moving member 2. When the operator releases the pressure on the insulating sleeve 9, the insulating bottom plate 11 is reset under the thrust of the elastic member 4, so that the contact returns to directly below the longitudinal moving member 2. During the resetting process of the insulating bottom plate 11, the second abutment 6 and the first abutment 5 slide and rub, and at the same time, the second abutment 6 generates a longitudinal thrust on the first abutment 5 to make the insulating sleeve 9 slide upward and reset.

[0038] Specifically, the elastic member 4 is placed in the slide groove 13 . The elastic member 4 is a spring. One end of the elastic member 4 is fixed in the slide groove 13 by gluing, and the other end of the elastic member 4 is fixed on the insulating bottom plate 11 by gluing.

[0039] Specifically, a plurality of fixing holes 14 are formed on the base 1 , specifically four fixing holes 14 , so that screws can pass through the fixing holes 14 to fix the base 1 on the wall.

[0040] Specifically, an annular baffle 15 is provided at the upper end of the base 1, and the inner ring of the annular baffle 15 is for the bottom end of the bulb to pass through. The annular baffle 15 abuts against the upper end of the longitudinal moving member 2 to limit the maximum distance of the longitudinal moving member 2 moving upwards and prevent the longitudinal moving member 2 from falling off the base 1. The annular baffle 15 is threadedly connected to the upper end of the base 1. When the longitudinal moving member 2 needs to be replaced, the annular baffle 15 can be unscrewed from the base 1 to remove the longitudinal moving member 2 from the upper end of the base 1.
