Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, specifically relating to a lamp holder anti-slip structure. Background Technology

[0002] A lamp holder is a device used to support a lamp. It is typically used to fix the lamp in place and connect the lamp's contacts to a power source, thereby supplying power to the lamp to meet lighting needs.

[0003] Chinese Patent No. CN210350170U discloses a lamp holder that uses a sliding member to drive a metal lever and a metal spring to clamp the lamp source connection terminal. However, after long-term use, the metal lever may cause the sliding member to slip unexpectedly due to aging or mechanical fatigue. The lack of constraint on the multi-dimensional displacement of the sliding member easily leads to electrical connection failure, affecting the stability of the electrical connection between the lamp and the lamp holder, and preventing the lamp from providing continuous illumination. Therefore, an improved anti-slip structure for the lamp holder is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a lamp holder anti-slip structure, which aims to solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A lamp holder anti-slip structure includes a base and a sliding member slidably connected to the base. The base has strip-shaped grooves on both sides and metal sheets are placed in the strip-shaped grooves. The sliding member has an integral extension at its tail end. The extension is hollow and has an opening at the bottom for connecting a power cord. The upper surface of the tail end of the base has a limiting groove. The outer surface of the limiting groove has a through opening for a limiting hole. A limiting member is inserted into the limiting groove. The limiting member has a connecting plate. An anti-slip baffle and an insert plate are fixedly installed on the lower surface of the connecting plate. The anti-slip baffle is I-shaped and has balance plates integrally provided at both ends. The insert plate has a protruding limiting protrusion.

[0006] In a preferred embodiment of the present invention, the limiting member has a columnar structure for both the anti-detachment baffle and the insert plate, and the ends and edges of the anti-detachment baffle and the insert plate are chamfered. The depth of the limiting groove is greater than the length of the insert plate, and the limiting groove is interference-fitted with the insert plate.

[0007] In a preferred embodiment of this utility model, the balance plate is attached to and slidably connected to the outer wall of the limiting groove.

[0008] In a preferred embodiment of this utility model, a gap is provided between the insert plate and the balance plate, and the width of the gap is consistent with the wall thickness of the limiting groove.

[0009] In a preferred embodiment of the present invention, a gripping part is fixedly installed on the upper end face of the limiting member, and the surface of the gripping part is provided with anti-slip texture.

[0010] In a preferred embodiment of this utility model, the length of the anti-detachment baffle is less than the height of the extension, so that the anti-detachment baffle avoids squeezing the power cord during the insertion process.

[0011] In a preferred embodiment of this utility model, the limiting hole and the limiting protrusion are adapted to each other, the difference between the diameter of the limiting hole and the diameter of the limiting protrusion is 0.05-0.15mm, and the end face of the limiting protrusion is hemispherical.

[0012] In a preferred embodiment of this utility model, the width of the balance plate is the same as the width of the connecting plate, and the end of the extension is stopped by the limiting member after it is inserted into the limiting groove.

[0013] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include: This utility model's lamp holder anti-slip structure aims to prevent the metal plates on the sliding component from losing their clamping and fixing effect due to aging or mechanical fatigue, thus avoiding accidental slippage of the sliding component and resulting in electrical connection failure. In this case, the user presses the gripping part to fully insert the limiting component into the limiting groove through the insert plate and fix it in place. This, in turn, abuts against the extension at the tail end of the sliding component, thereby achieving mechanical limiting of the extension and the entire sliding component. This avoids the risk of slippage of the sliding component, constrains the displacement of the sliding component, and achieves the function of preventing the sliding component from slipping. It maintains a stable electrical connection between the lamp and the lamp holder, maintains the continuous lighting effect of the lamp, and extends the service life of the lamp.

Detailed Implementation

[0016] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0017] Example: like Figure 1-5 As shown, this embodiment provides a lamp holder anti-slip structure, including a base 1 and a sliding member 2 slidably connected to the base 1. The base 1 has strip-shaped grooves 3 on both sides and a metal sheet 4 is provided in the strip-shaped grooves 3. The sliding member 2 has an extension 6 integrally provided at its tail end. The extension 6 is hollow and has an opening at the bottom for connecting a power cord 5. The upper end face of the tail end of the base 1 has a limiting groove 7. The outer surface of the limiting groove 7 has a through opening for a limiting hole 8. A limiting member 9 is inserted into the limiting groove 7. The limiting member 9 has a connecting plate 11. An anti-slip baffle 12 and an insert plate 13 are fixedly installed on the lower end face of the connecting plate 11. The anti-slip baffle 12 is in the shape of an "I" and has a balance plate 14 integrally provided at both ends. A limiting protrusion 15 protrudes from the insert plate 13.

[0018] In a specific application scenario, to prevent the metal plate 4 on the slider 2 from losing its clamping and fixing effect due to aging or mechanical fatigue, thus causing the slider 2 to slip off unexpectedly and resulting in electrical connection failure, the user presses down on the grip part 10 to fully insert the limiting member 9 into the limiting groove 7 through the insertion plate 13 and fix it in place. This, in turn, abuts against the extension 6 at the tail end of the slider 2, thereby achieving mechanical limiting of the extension 6 and the slider 2 as a whole, achieving the function of preventing the slider 2 from slipping off and maintaining a stable electrical connection between the lamp and the lamp holder. The following describes the lamp holder anti-slip structure of this utility model in further detail with reference to this application scenario.

[0019] Furthermore, referring to Figure 1-5The limiting member 9 has a columnar structure for both the anti-detachment baffle 12 and the insert plate 13, and the ends and edges of the anti-detachment baffle 12 and the insert plate 13 are chamfered. The depth of the limiting groove 7 is greater than the length of the insert plate 13, and the limiting groove 7 is interference-fitted with the insert plate 13.

[0020] In this embodiment, during the process of supporting and fixing the lamp fixture with the lamp holder, in order to facilitate the insertion of the limiting member 9 into the limiting groove 7, both the anti-detachment baffle 12 and the insertion plate 13 are columnar structures, and the ends and edges of the anti-detachment baffle 12 and the insertion plate 13 are chamfered, thereby ensuring the smooth insertion of the insertion plate 13 into the limiting member 9 and avoiding the insertion jamming of the limiting member 9; at the same time, in order to ensure that the insertion plate 13 can be fully inserted into the limiting groove 7, the depth of the limiting groove 7 is set to be greater than the length of the insertion plate 13, so as to fully accommodate the insertion plate 13 and maintain the stable insertion state of the insertion plate 13, thereby achieving the stable insertion of the insertion plate 13 and the limiting member 9. By setting the interference fit between the limiting groove 7 and the insertion plate 13, the tight fit between the limiting groove 7 and the insertion plate 13 after insertion is maintained, preventing the insertion plate 13 from falling out of the limiting groove 7.

[0021] In more detail, refer to Figure 1-5 The balance plate 14 is attached to the outer wall of the limiting groove 7 and maintains a sliding connection.

[0022] In this embodiment, during the insertion of the limiting member 9, in order to control the insertion direction of the limiting member 9, the balance plate 14 is set to be attached to the outer wall of the limiting groove 7 and kept in a sliding connection, so that the outer wall of the limiting groove 7 forms a sliding guide for the balance plate 14, thereby restricting the balance plate 14 to only move vertically up and down along the outer wall of the limiting groove 7, without lateral displacement, keeping the insertion of the balance plate 14 and the limiting member 9 stable, and preventing axial deviation and slippage of the limiting member 9 during the insertion process by constraining the lateral displacement of the balance plate 14.

[0023] More preferably, refer to Figure 1-5 A gap is provided between the insert plate 13 and the balance plate 14, and the gap width is consistent with the wall thickness of the limiting groove 7.

[0024] In this embodiment, as the limiting member 9 descends during the insertion process, it will collide with the outer wall of the limiting groove 7. In order to reserve an insertion gap, a gap is provided between the insertion plate 13 and the balance plate 14, and the gap width is consistent with the wall thickness of the limiting groove 7. This ensures that the insertion process of the limiting member 9 is independent and will not conflict with the setting of the limiting groove 7. At the same time, the gap design can absorb vibration energy, absorb assembly tolerance, reduce structural fatigue, and increase the number of insertions and service life of the limiting member 9.

[0025] More preferably, refer to Figure 1-5A gripping part 10 is fixedly installed on the upper end face of the limiting part 9, and the surface of the gripping part 10 is provided with anti-slip texture.

[0026] In this embodiment, in order to facilitate the user's insertion operation of the limiting member 9, a gripping part 10 is fixedly installed on the upper surface of the limiting member 9 for the user to grip. At the same time, anti-slip texture is provided on the surface of the gripping part 10 to enhance the convenience of the user in the insertion process of the limiting member 9.

[0027] Furthermore, referring to Figure 1-5 The length of the anti-detachment baffle 12 is less than the height of the extension 6, so that the anti-detachment baffle 12 avoids squeezing the power cord 5 during the insertion process.

[0028] In this embodiment, since the lamp and the lamp holder need to maintain an electrical connection through the power cord 5, in order to avoid the power cord 5 being squeezed during the insertion and pressing of the limiting member 9, the length of the anti-detachment baffle 12 is set to be less than the height of the extension 6, so that the power cord 5 will not be squeezed when the anti-detachment baffle 12 is fully inserted vertically, thus reserving space for the power cord 5, maintaining the independent setting of the power cord 5, and thus maintaining a stable electrical connection between the lamp and the lamp holder.

[0029] Furthermore, referring to Figure 1-5 The limiting hole 8 and the limiting protrusion 15 are adapted to each other. The difference between the diameter of the limiting hole 8 and the diameter of the limiting protrusion 15 is 0.05-0.15mm, and the end face of the limiting protrusion 15 is hemispherical.

[0030] In this embodiment, after the limiting member 9 is fully inserted into the limiting groove 7 through the insert plate 13, in order to further maintain the insertion stability of the insert plate 13 in the limiting groove 7 and prevent slippage, a limiting protrusion 15 adapted to the limiting hole 8 is provided so that the limiting protrusion 15 and the limiting hole 8 are engaged to achieve precise alignment, maintain the longitudinal stability of the insert plate 13, prevent the insert plate 13 from slipping out of the limiting groove 7, and thus maintain the overall insertion stability of the limiting member 9; at the same time, the end face of the limiting protrusion 15 is set to be hemispherical to reduce the sliding resistance between the insert plate 13 and the inner wall of the limiting groove 7 during the insertion process, making the insertion and removal process of the insert plate 13 smoother and increasing the convenience and practicality of the limiting member 9 during operation.

[0031] More specifically, refer to Figure 1-5 The width of the balance plate 14 is the same as the width of the connecting plate 11, and after the limiting member 9 is inserted into the limiting groove 7, it abuts and limits the end of the extension 6.

[0032] In this embodiment, after the limiting member 9 is fully inserted into the limiting groove 7 through the insert plate 13 and fixed, since the width of the balance plate 14 is the same as the width of the connecting plate 11, the sides of the connecting plate 11 and the balance plate 14 are on the same plane, thereby abutting the extension 6 at the tail end of the sliding member 2, thereby realizing the mechanical limiting of the extension 6 and the entire sliding member 2, achieving the function of preventing the sliding member 2 from slipping and maintaining the stable electrical connection between the lamp and the lamp holder.

[0033] Working principle: The anti-slip structure of this utility model for lamp holders, during the process of fixing and powering the lamp, firstly, by moving the sliding member 2 to the top of the base 1, the sliding member 2 is clamped and fixed by the metal plate 4 on the base 1, and the lamp is electrically connected through the power cord 5. After power is applied, in order to prevent the metal plate 4 on the sliding member 2 from losing its clamping effect due to aging or mechanical fatigue, causing the sliding member 2 to accidentally slip off and resulting in electrical connection failure, the user can operate the grip part 1. Press down to insert the limiting member 9 vertically into the limiting groove 7, and set a limiting protrusion 15 that matches the limiting hole 8 so that the limiting protrusion 15 engages with the limiting hole 8 to achieve precise alignment, maintain the longitudinal stability of the insert plate 13, prevent the insert plate 13 from slipping out of the limiting groove 7, and thus maintain the overall insertion stability of the limiting member 9; at the same time, the end face of the limiting protrusion 15 is set to be hemispherical to reduce the sliding resistance between the insert plate 13 and the inner wall of the limiting groove 7 during the insertion process, making the insertion and removal process of the insert plate 13 smoother; After the limiting member 9 is fully inserted into the limiting groove 7 and fixed by the insert plate 13, since the width of the balance plate 14 is the same as the width of the connecting plate 11, the sides of the connecting plate 11 and the balance plate 14 are on the same plane, thereby abutting the extension 6 at the tail end of the sliding member 2, thereby realizing the mechanical limiting of the extension 6 and the entire sliding member 2, achieving the function of preventing the sliding member 2 from slipping and maintaining the stable electrical connection between the lamp and the lamp holder; A gap is provided between the insertion plate 13 and the balance plate 14, and the gap width is consistent with the wall thickness of the limiting groove 7, so as to keep the insertion process of the limiting part 9 independent and not conflict with the setting of the limiting groove 7. At the same time, the gap design can absorb vibration energy, absorb assembly tolerance, reduce structural fatigue, and increase the insertion number and service life of the limiting part 9.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
