Description

Technical Field

[0001] The utility model relates to the technical field of lamp caps, and specifically relates to a lamp cap ejection structure. Background Art

[0002] LED lamps usually include a lamp body, and a chamber is usually arranged on the lamp body for installing components such as electrical components; a lamp cap is usually covered on the chamber, and the lamp cap is generally directly installed on the lamp body through a rotating shaft. When the lamp cap is opened, it usually automatically closes under the action of its own gravity, which is not convenient for the disassembly, installation and maintenance of the electrical components in the lamp body. In the prior art, a support rod is usually used to support the lamp cap to prevent it from closing, but this method is not convenient for controlling the opening and closing of the lamp cap. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a lamp cap ejection structure, which solves the problem that the existing method is not convenient for controlling the opening and closing of the lamp cap.

[0004] To achieve the above object, the utility model provides the following technical solution: a lamp cap ejection structure, including a lampshade, a receiving chamber is opened on the lampshade, the upper end of the receiving chamber is rotatably covered with a lamp cap, and an ejection mechanism for controlling the lamp cap to cover or eject from the receiving chamber is installed on the lampshade at one end of the lamp cap;

[0005] The ejection mechanism includes an acting chassis and a pressing member installed on the acting chassis. One end of the pressing member is provided with a buckling member for establishing or releasing the connection with the lamp cap. The pressing member includes a member placing groove opened on the lampshade and an acting plate covering the member placing groove. The acting chassis is arranged in the member placing groove, and a pressing slide rod is slidably arranged on the acting chassis. The pressing slide rod is installed on a connecting cover plate connected to the acting plate;

[0006] The buckling member includes a central shaft slidably arranged on the acting chassis. The central shaft penetrates through the structure extending outwards from the acting chassis and is connected to the acting plate. A tension spring is connected to the left end of the central shaft.

[0007] In one embodiment, the acting chassis includes a bottom plate and front and rear side plates connected to the bottom plate. Left and right extending chutes are opened on both the front and rear side plates. The central shaft is placed in the chutes, and a slideway is arranged at the left end of the front and rear side plates. The pressing slide rod is arranged on the slideway.

[0008] In one embodiment, the lamp cap includes a cover plate and an elastic pressing member arranged at the lower end of the cover plate for acting with the central shaft. A rotating seat for rotating and positioning the cover plate is arranged opposite to the elastic pressing member;

[0009] The pressing member includes a mounting plate installed at the bottom of the cover plate. A Z-shaped plate is screwed onto the mounting plate. One end of the Z-shaped plate extends outside the cover plate structure. When the cover plate covers the accommodation bin, the Z-shaped plate is in contact with the central axis. The maximum movement distance of the central axis on the slideway is greater than the structural length of the connection between the Z-shaped plate and the central axis.

[0010] In one embodiment, the connection between the connection cover plate and the acting plate is through bolt connection. The pressing slide rod penetrates through the connection cover plate before and after and drives the connection cover plate to generate displacement after being stressed.

[0011] In one embodiment, the inside of the component placement groove is connected to the connection cover plate through an inclined tension spring.

[0012] In one embodiment, the acting plate is marked with acting icons.

[0013] Compared with the prior art, the present utility model provides a lamp cover ejection structure, which has the following beneficial effects:

[0014] In the technical solution disclosed by the present utility model, by installing an ejection structure at one end of the lamp cover, the state basis for opening or closing the accommodation bin can be established. Through the control of the lamp cover by the ejection structure, by pressing the acting plate, the central axis can be indirectly promoted to release the abutment against the lamp cover, thereby removing the covering of the lamp cover on the accommodation cavity. On the other hand, based on the fact that the ejection structure returns to the initial position after the external force disappears, the situation that the lamp cover rebounds and closes again due to gravity after ejection is solved.

[0015] In the present utility model, both the central axis and the connection cover plate are connected to the component placement groove through tension springs, so that they can be continuously pulled during their movement process, which is convenient for returning to the initial position after the external force disappears, forming an occlusion for the lamp cover and avoiding the situation that the lamp cover rebounds to the initial position and closes after ejection.

Specific embodiments

[0023] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present utility model.

[0025] Figures 1 - 5 This is an embodiment of the present utility model. The specific problem targeted by this specific embodiment is as follows: Existing LED lamps usually include a lamp body, and a chamber is usually provided on the lamp body for installing components such as electrical components. A lamp cover 3 is usually covered on this chamber. The inventor found during specific operations that since the lamp cover 3 is generally directly installed on the lamp body through a rotating shaft, when the lamp cover 3 is opened, it usually bounces back to the initial position and closes under the action of its own gravity, thus making it inconvenient to disassemble, install, and maintain the electrical components in the lamp body.

[0026] In the prior art, a support rod is usually used to support the lamp cover 3 to prevent it from closing. However, this method requires an external support rod or the setting of a support rod and a cavity for accommodating the support rod inside the lamp shade 1. On the one hand, the external support rod is easy to lose. On the other hand, setting a support rod inside the wind shield increases the cost and requires an increase in the space inside the lamp shade 1, which is not conducive to the control of production costs, and it is not convenient to control the opening and closing of the lamp cover using the support rod.

[0027] Based on the above considerations, the inventor has elaborated a lamp cover pop-up structure. This scheme utilizes the installation of a pop-up structure at one end of the lamp cover 3 to establish the basis for the open or closed state of the accommodating chamber 2. The pop-up structure controls the lamp cover 3 and presses the action plate 422 to indirectly promote the central axis 431 to release the abutment against the lamp cover 3, thereby releasing the lamp cover 3 from covering the accommodating chamber. On the other hand, the pop-up structure returns to the initial position after the external force disappears, thereby solving the problem of the lamp cover 3 closing again due to gravity rebound after being popped out.

[0028] A lamp cover pop-up structure is specifically provided with a lampshade 1, a storage chamber 2 is provided on the lampshade 1, the upper end of the storage chamber 2 is rotatably covered with a lamp cover 3, a pop-up mechanism 4 for controlling the lamp cover 3 to cover or pop off the storage chamber 2 is installed on the lampshade 1 at one end of the lamp cover 3, the pop-up mechanism 4 includes an action chassis 41 and a pressing member 42 installed on the action chassis 41, one end of the pressing member 42 is provided with a fastening member 43 for establishing or releasing the connection with the lamp cover 3, the pressing member 42 includes a mounting groove 421 provided on the lampshade 1 and an action plate 422 covering the mounting groove 421, and an action icon is indicated on the action plate 422. The action chassis 41 is provided in the mounting groove 421, a pressing slide bar 423 is slidably provided on the action chassis 41, and the pressing slide bar 423 is installed on a connection cover plate 424 connected to the action plate 422, and the inside of the mounting groove 421 is connected to the connection cover plate 424 through an inclined tension spring 432. The connecting cover plate 424 is connected to the action plate 422 by bolts, and the pressing slide bar 423 penetrates the connecting cover plate 424 in front and behind and drives the connecting cover plate 424 to move after receiving force. By pressing the connection of the slide bar 423 on the connecting cover plate 424, the movement of the pressing slide bar 423 is promoted to move the connecting cover plate 424, thereby forming a movement basis for the connecting cover plate 424. The utility model is connected to the mounting groove 421 through the tension spring 432 on the central axis 431 and the connecting cover plate 424, so that it can be subjected to continuous tension during its movement, so that it is convenient to return to the initial position after the external force disappears, thereby forming a shielding to the lamp cover 3, and avoiding the situation that the lamp cover 3 pops out and rebounds to the initial position to close.

[0029] The snap-in part 43 includes a central shaft 431 that acts on the chassis 41 and slides therein. The central shaft 431 passes through the structure extending outward from the chassis 41 and is connected to the actuating plate 422. A tension spring 432 is connected to the left end of the central shaft 431. The chassis 41 includes a bottom plate 411 and front and rear side plates 412 connected to the bottom plate 411. Slide grooves 413 extending left and right are provided on both the front and rear side plates 412. The central shaft 431 is placed in the slide grooves 413. Slideways 414 are provided at the left ends of the front and rear side plates 412. The pressing slide rod 423 is arranged on the slideways 414. The lamp cover 3 includes a cover plate 31 and a pressing member 32 provided at the lower end of the cover plate 31 for acting on the central shaft 431. Opposite to the pressing member 32, a rotating seat 33 for rotating and positioning the cover plate 31 is provided. The pressing member 32 includes a mounting plate 321 mounted on the bottom of the cover plate 31. A Z-shaped plate 322 is screwed onto the mounting plate 321. One end of the Z-shaped plate 322 extends outside the structure of the cover plate 31. The Z-shaped plate 322 is in contact with the central shaft 431 when the cover plate 31 covers the receiving bin 2. The maximum movement distance of the central shaft 431 on the slideway 414 is greater than the structural length of the connection between the Z-shaped plate 322 and the central shaft 431. In specific use, first, manually press the actuating plate 422. Through the connection with the actuating plate 422, the connecting cover plate 424 rotates at an angle under the connection with the central shaft 431, and based on the sliding of the pressing slide rod 423 on the front and rear side walls of the chassis 41, the connecting cover plate 424 is displaced, and the central shaft 431 is synchronously pulled to slide rightward in the slide groove 413. During the sliding of the central shaft 431, the force received by the Z-shaped plate 322 placed at the bottom of the central shaft 431 and in contact with it gradually disappears. Finally, after the central shaft 431 disengages from the contact with the Z-shaped plate 322, the external force on the Z-shaped plate 322 disappears, and the entire lamp cover 3 pops out. At the same time, the hand is removed from the contact with the actuating plate 422. Under the action of the tension spring 432, the connecting cover plate 424 pushes the pressing slide rod 423 back to the initial position. At the same time, the central shaft 431 also returns to the initial position due to the push of the connecting cover plate 424. Furthermore, even if the cover plate 31 rebounds after popping out, the Z-shaped plate 322 cannot return to the initial position due to the blockage of the central shaft 431, that is, the cover plate 31 will always remain in the popped-out state due to the blockage of the Z-shaped plate 322.
