Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a modular lamp holder structure. Background Technology

[0002] The lamp holder is an indispensable basic component of a lighting system. Its main function is to reliably fix the bulb to the power supply line and make electrical connections to achieve lighting.

[0003] In existing technologies, the vast majority of suspended lamp holders adopt an integrated structural design. During installation, the user needs to lift the entire lamp holder to the designated position, thread the power cord through the lamp holder, and connect it to the terminal block within a confined space. This operation is not only laborious, but also difficult and inefficient when performed at heights or in complex environments.

[0004] Furthermore, the drawbacks of this integrated structure are particularly pronounced during maintenance and replacement. When the bulb interface portion of the lamp holder (such as the screw or contact plate) wears, oxidizes, or is damaged due to long-term use, because it is fixed to the wiring portion, the user must remove the entire lamp holder from the power cord and replace it with a new one. This means that the tedious and inconvenient work of disconnecting and rewiring the wires is required again, which not only increases the complexity and time cost of maintenance, but also poses a safety challenge for non-professionals.

[0005] In summary, the integrated design of existing lamp holders leads to problems such as inconvenience, low efficiency, and high cost during installation and maintenance.

[0006] Therefore, this utility model proposes a modular lamp holder structure to address the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems that the integrated design of the lamp holder structure in the existing technology leads to complicated installation and wiring, complex maintenance and replacement process and high cost, this utility model aims to provide a modular lamp holder structure with improved structure that can effectively solve the above problems.

[0008] This utility model provides a modular lamp holder structure, including a mounting component and a connecting component that can be plugged into the mounting component; the mounting component includes a hollow inner shell, and the connecting component includes a socket that can be plugged into the inner shell; the modular lamp holder structure also includes an outer shell.

[0009] The inner shell has a first threaded layer on its outer peripheral wall and at least one radially movable retaining ball on its outer peripheral wall; the socket has an annular groove on its outer peripheral wall for accommodating the retaining ball.

[0010] Furthermore, the outer shell is a sleeve-shaped structure, and its inner wall is provided with threads that cooperate with the first screw layer. The outer shell is fitted onto the outside of the inner shell by means of a threaded connection. When the socket is inserted into the inner shell to make the retaining ball engage with the retaining groove, the inner wall of the tightened outer shell can radially press against and restrict the retaining ball to prevent it from coming out of the retaining groove, thereby locking the mounting component and the connecting component together.

[0011] Preferably, the connecting assembly further includes a connecting seat, which is fixedly connected to the lower end of the socket. The connecting seat has an internal cavity for screwing in a light bulb, and the inner wall of the connecting seat is provided with a second threaded layer to achieve threaded engagement with a standard light bulb.

[0012] Preferably, the bottom center of the connector is also provided with a flexible power-conducting lever, which is used to form a flexible contact with the bottom electrode of the bulb to ensure stable and reliable power supply.

[0013] Preferably, a terminal block is fixedly connected to the top of the socket. The terminal block is provided with terminals for connecting external wires and is electrically connected to the power-conducting lever and the second threaded layer through internal conductive components, forming a complete power supply circuit module.

[0014] Preferably, the mounting assembly further includes a mounting plate, which is disc-shaped and fixedly connected to the upper end of the inner shell, serving as the top support structure of the entire mounting assembly and enhancing the overall structural strength.

[0015] Preferably, a fixing block is fixedly connected to the top of the mounting plate, and the fixing block has a wire hole for the power supply line to pass through, providing a clear and centralized channel for the introduction and fixing of the wire.

[0016] Preferably, the mounting assembly further includes a hook, which is rotatably connected to the top of the mounting plate via a pivot structure. This design allows the lamp head to be freely adjusted in angle when suspended to adapt to different installation environments and needs.

[0017] Preferably, the outer edge of the opening end of the inner shell is fixedly connected with an outwardly protruding limiting ring. The limiting ring is designed to axially block the outer shell to prevent it from completely falling off the inner shell during loosening and disassembly, thus preventing the loss of parts.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome operation and high cost in the installation, wiring and subsequent maintenance and replacement of integrated lamp heads in the prior art by designing the lamp head structure as a separable installation component and connection component, and using a combination of snap-fit ​​and threaded locking for fixation. It achieves the beneficial effects of simplifying the installation process and reducing maintenance difficulty and cost.

[0019] 2. This utility model achieves quick snap-fit ​​positioning by setting a snap-fit ​​ball and a snap-fit ​​groove, and then uses a screw-tightened outer shell to radially press and lock the snap-fit ​​ball. This double fixing method solves the safety hazards of insufficient connection strength and easy accidental detachment due to vibration or external force in traditional snap-fit ​​structures, and achieves the technical effect of fast, convenient and stable connection with high safety.

[0020] 3. This utility model solves the problem of some lamp holders having a single installation method and easy loss of parts during disassembly by integrating a rotating hook on the installation component and setting a limiting ring to prevent the outer shell from falling off. It achieves the beneficial effects of flexible installation method, good structural integrity and improved user experience. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 4This utility model provides a modular lamp holder structure, which aims to solve the problems of complicated installation and wiring and difficult maintenance and replacement caused by the integrated lamp holder in the prior art.

[0025] like Figure 1 As shown, the modular lamp holder structure includes a mounting component 1 and a connecting component 2 that are separate but lockable to each other. The mounting component 1 is used to pre-fix and provide a passage for the wires, while the connecting component 2 is used to connect the bulb and the wires. The two components are connected by plugging and threading to form a complete lamp holder.

[0026] like Figure 3 As shown, the core locking scheme of the structure is as follows: the mounting component 1 includes a hollow inner shell 106, and a first threaded layer 105 is provided on the outer peripheral wall of the inner shell 106. At least one radially retractable locking ball 107 is provided on the outer wall of the inner shell 106 and below the first threaded layer 105. The locking ball 107 is used to achieve quick locking and positioning.

[0027] The connecting component 2 includes a socket 202 that can be inserted into the hollow cavity of the inner shell 106. The outer peripheral wall of the socket 202 is provided with an annular groove 203 corresponding to the ball 107. When the socket 202 is inserted into the inner shell 106, the groove 203 is used to accommodate the ejected ball 107.

[0028] Mounting assembly 1 also includes a sleeve-shaped outer shell 101, the inner wall of which is machined with threads that match the first threaded layer 105. The outer shell 101 is rotatably fitted onto the outside of the inner shell 106 through the threaded structure and can move along the axial direction of the inner shell 106. The outer shell 101 is used to finally lock mounting assembly 1 and connecting assembly 2.

[0029] During assembly, firstly, the socket 202 of the connecting component 2 is aligned and inserted into the inner shell 106 of the mounting component 1. During insertion, the retaining ball 107 is compressed and retracts. When the socket 202 reaches the predetermined position, the retaining ball 107 automatically pops outward under the elastic force of the internal spring and locks into the slot 203, thereby achieving the initial axial positioning and anti-detachment connection of the two components. Subsequently, the outer shell 101 is rotated clockwise to tighten downward through the thread engagement with the first threaded layer 105. After the outer shell 101 is tightened in place, its inner wall will tightly press and restrict the retaining ball 107 from the outer periphery, thereby firmly locking the retaining ball 107 inside the slot 203, preventing it from retracting inward and detaching, and finally completing the secure and reliable locking between the mounting component 1 and the connecting component 2.

[0030] To achieve the full functionality of the modular lamp head, this embodiment further refines the structure of the connecting component 2 and the mounting component 1.

[0031] Please refer to the following carefully. Figure 3 and Figure 4 The specific structure of connecting component 2 will be described in detail below.

[0032] The connecting component 2 also includes a connecting seat 201, which is fixedly connected to the lower end of the socket 202. Together, they form the main frame of the connecting component 2. The interior of the connecting seat 201 is a cavity structure, and its inner wall is provided with a second thread layer 205. The thread specification of the second thread layer 205 matches the screw hole of the standard light bulb and is used to screw in and fix the light bulb.

[0033] At the bottom center of the connector 201, there is also a flexible power-on lever 206. The power-on lever 206 is used to contact the center electrode at the bottom of the screwed-in bulb to form one pole of the power supply circuit.

[0034] At the top of the socket 202, a terminal block 204 is fixedly connected. The terminal block 204 is provided with a terminal structure for pressing or locking the wire core. Its function is to serve as the access point for the external power cord. The terminal block 204 forms a reliable electrical connection with the power-conducting lever 206 and the second threaded layer 205 through internal conductive elements, thereby safely delivering external power to the two electrodes of the bulb.

[0035] This structural design makes the connecting component 2 a functionally independent electrical module. Users can easily connect the wires to the terminal block 204 and pre-install the light bulb before assembling it with the mounting component 1.

[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, for ease of hanging and fixing the entire lamp head structure, please refer to... Figure 2 and Figure 3 The mounting assembly 1 also includes a mounting plate 102, which is disc-shaped and fixedly connected to the upper end of the inner shell 106, serving as the top support platform for the entire mounting assembly 1.

[0037] On the top of the mounting plate 102, a fixed block 103 with an upward protrusion is fixedly connected. A wire hole 104 for the power supply wire to pass through is opened at the center of the fixed block 103. An insulating protective layer may be provided on the edge of the wire hole 104 to prevent the outer sheath of the wire from being scratched when it passes through.

[0038] As a further preferred embodiment, in order to achieve flexible suspension installation, the mounting assembly 1 also includes a hook 3. The hook 3 is rotatably connected to the top of the mounting plate 102 through a pivot structure. The user can adjust the angle of the hook 3 according to actual needs, so as to conveniently suspend the entire lamp head on the hanging rope, bracket or the hanging point reserved in the ceiling.

[0039] As another preferred embodiment, to prevent the outer casing 101 from being accidentally twisted out and lost during disassembly, please refer to... Figure 3 A limiting ring 108 protruding outward is fixedly connected to the outer edge of the opening end of the inner shell 106. The outer diameter of the limiting ring 108 is larger than the inner thread diameter of the outer shell 101. When the outer shell 101 is loosened outward, the end of its inner thread will be axially blocked by the limiting ring 108, thereby ensuring that the outer shell 101 always stays on the inner shell 106.

[0040] The working principle of this modular lamp holder structure is as follows: During installation, the user first passes the external wire through the hook 3 on the mounting component 1, the wire hole 104 on the fixing block 103, and the hollow cavity of the inner shell 106 in sequence. Then, the wire core is stripped and firmly connected to the terminal block 204 at the top of the connecting component 2.

[0041] Next, the user aligns the wired connecting component 2 with the open end of the mounting component 1 and pushes the socket 202 into the inner shell 106. During this process, the outer wall of the socket 202 will first press the retaining ball 107 to retract inward. When the socket 202 is fully pushed into place, the retaining groove 203 on its outer peripheral wall moves to the position of the retaining ball 107. The retaining ball 107 then pops outward under its own elastic potential energy and gets stuck in the retaining groove 203. At this time, the two components have achieved preliminary axial fixation through the snap-fit ​​method, which can prevent accidental slippage.

[0042] Subsequently, the user screws the outer casing 101 clockwise. The outer casing 101 engages with the first threaded layer 105 on the outer wall of the inner casing 106 through its inner wall threads, and begins to move downward along the axial direction, gradually covering the area where the retaining ball 107 is located. When the outer casing 101 is fully tightened, its solid inner wall will press the retaining ball 107 tightly into the retaining groove 203 from the radial direction, completely restricting the possibility of the retaining ball 107 retracting inward, thereby achieving a strong lock on the two components, ensuring the long-term stability of the mechanical connection and the reliability of the electrical contact.

[0043] After assembling the lamp holder body, screw the bulb into the second thread layer 205 of the connector 201 through its screw hole until the center electrode at the bottom of the bulb makes good contact with the energizing lever 206, and the bulb installation is complete.

[0044] Finally, the assembled lamp head structure is suspended in the usage position by the hook 3 at the top, and it can be powered on and used. When it is necessary to repair or replace the lamp head, simply unscrew the outer shell 101 in the opposite direction to easily unlock it, and remove the connecting component 2 for replacement. The whole process does not require disconnecting and re-handling the wires on the ceiling side, making the operation extremely convenient.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
