[0023] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

For example, they may refer to direct connection or indirect connection through an intermediate medium; fixed connection or detachable connection or integral molding; mechanical connection; and internal communication between two components or interaction between two components. Those skilled in the art can reasonably determine the specific meanings of these terms in the present invention based on the specific content of the technical solution.

[0027] The lamp body bracket is an important component of the lamp, mainly used to support and fix the various components of the lamp to ensure the stability and safety of the lamp. The lamp body bracket is usually made of metal materials, such as copper, iron, aluminum or ceramics, which have good conductivity and mechanical strength. Some lamp body brackets can rotate, allowing the lamp to be disassembled and assembled relative to the bracket while supporting and fixing the lamp. The usual disassembly and assembly method is to fix the lamp to the bracket by fastening it with fasteners, but the disassembly and assembly process is relatively complicated, time-consuming, and requires the help of tools. Therefore, how to achieve rapid disassembly and assembly is a technical problem that needs to be solved urgently by those skilled in the art.

[0028] See Figures 1 to 6To address the aforementioned issues, a first aspect of an embodiment of the present application provides an easily removable device 10 for quick installation and removal with a mounting member 71. The easily removable device 10 can be used in lighting equipment, display devices, or any other device involving mechanical assembly and disassembly. The mounting member 71 can be any structure on the device to be installed. The easily removable device 10 includes a housing 20, a locking knob 30, and a transmission limiter assembly 40. The locking knob 30 is rotatably connected to the housing 20 and partially exposed outside the housing 20. For example, the locking knob 30 includes a rotating handle, and all other components of the locking knob 30, except the handle, are housed within a housing cavity within the housing 20. The locking knob 30 is rotatably connected to the housing 20 and can rotate relative to the housing 20 between a first rotation angle and a second rotation angle. However, these examples are merely representative of the angles and are not intended to limit the rotation of the locking knob 30 to other angles. The locking knob 30 includes an abutment curved surface 31 and a locking catch. The abutment curved surface 31 is concave to form a rotation locking groove 311. The abutting curved surface 31 is an arc surface, and the rotation locking groove 311 is located on the arc surface. The rotation center of the locking handle 30 is located at the center of the circle corresponding to the arc surface. The transmission limit assembly 40 includes a locking pin 41, a first reset member 42, and a second reset member 43. All three are arranged in the accommodating cavity of the housing 20. The first reset member 42 and the second reset member 43 are both connected between the housing 20 and the locking pin 41. Among them, the first reset member 42 is used to drive the locking pin 41 to move along the first direction P1 toward the abutting curved surface 31; the second reset member 43 is used to drive the locking pin 41 to move in the opposite direction of the first direction P1. The driving force of the second reset member 43 on the locking pin 41 is greater than that of the first reset member 42. The driving force of the first reset member 42 and the second reset member 43 can come from elastic force or magnetic force. The mounting member 71 is provided with a buckle slot. During the installation process of the housing 20, the mounting member 71 first pushes the lock buckle into the housing 20, and the locking handle 30 rotates synchronously. When the buckle slot is aligned with the lock buckle, the lock buckle extends out of the housing 20 again to snap into the buckle slot. At this time, the locking handle 30 rotates and is in a posture of the first rotation angle. During the installation process of the mounting member 71 to the housing 20, the mounting member 71 remains in contact with the second reset member 43. Therefore, when the locking handle 30 is at the first rotation angle, the mounting member 71 is clamped by the lock buckle and the second reset member 43 to be locked and fixed. Specifically, when the locking handle 30 is at the first rotation angle, the locking pin 41 is driven by the first reset member 42 to abut against the abutting curved surface 31 along the first direction P1. The lock buckle extends out of the housing 20 to clamp the mounting member 71 with the second reset member 43.

[0029] See Figures 1 to 6When the mounting member 71 needs to be removed, the user rotates the locking handle 30 to the second rotation angle, causing the lock catch to retract into the housing 20 and separate from the mounting member 71. Simultaneously, the locking groove 311 is rotated until it is aligned with the locking pin 41. The locking pin 41 engages the locking groove 311, restricting the rotation of the locking handle 30. At this point, the locking handle 30 is locked, and the user can remove the mounting member 71 from the easily removable device 10. After the mounting member 71 is separated from the easily removable device 10, the second return member 43 begins to drive the locking pin 41 in the opposite direction of the first direction P1 to return to its original position, disengaging the locking pin 41 from the locking groove 311. The locking handle 30 can then be rotated to return to its original position.

[0030] See Figures 1 to 6 In some embodiments, the housing 20 has a mounting side, and the mounting member 71 is assembled to the mounting side of the housing 20. In one embodiment, the housing 20 is provided with a limiting groove on the mounting side, and the shape of the limiting groove matches the shape of the mounting member 71, for example, the limiting groove is a V-shaped groove structure or a rectangular groove structure. The limiting groove is provided with a first avoidance opening on the groove wall in the first direction P1, and a second avoidance opening on the groove wall in the second direction P2. The lock can extend out of the first avoidance opening as the locking handle 30 rotates to enter the limiting groove and buckle the buckling groove of the mounting member 71, or retract into the first avoidance opening to disengage the buckling groove. The vertical sliding component 432 protrudes on the mounting side to form a supporting portion 4321c. The supporting portion 4321c is exposed from the housing 20 and is located in the limiting groove before the mounting member 71 is installed. The supporting portion 4321c can be pushed from the limiting groove to the second avoidance opening by the mounting member 71 along the second direction P2 to leave the space of the limiting groove.

[0031] In one embodiment, a rotational reset member 50 is provided between the locking handle 30 and the housing 20. The rotational reset member 50 is used to drive the locking handle 30 to rotate so that the lock catch extends out of the housing 20. The rotational reset member 50 is, for example, a torsion spring, which drives the locking handle 30 to rotate from the second rotation angle to the first rotation angle, thereby driving the lock catch out of the housing 20. This allows the lock catch to more firmly engage the mounting member 71. At the same time, this reset drive mode also ensures that the easily removable device 10 is automatically ready for the next assembly, thereby improving convenience.

[0032] Specifically, the first reset member 42 may be a compression spring sleeved over the locking pin 41. The second reset member 43 includes a transverse slider 431 and a vertical sliding assembly 432. The transverse slider 431 is slidably connected to the housing 20 along a first direction P1. A transverse groove is provided in the housing 20's receiving cavity to limit the maximum movement of the transverse slider 431 along the first direction P1. The vertical sliding assembly 432 is slidably connected to the housing 20 along a second direction P2. A vertical groove is provided in the housing 20's receiving cavity to limit the maximum movement of the vertical sliding assembly 432 along the second direction P2. The vertical sliding assembly 432 partially extends out of the housing 20 to be driven by the mounting member 71 in the second direction P2. The locking pin 41 is slidably connected to the transverse slider 431 along the first direction P1. The vertical sliding assembly 432 is transmission-connected to the transverse slider 431 to drive the transverse slider 431 to move the locking pin 41 in the opposite direction of the first direction P1. The first direction P1 is perpendicular to the second direction P2.

[0033] To enable the transverse slider 431 to push the locking pin 41 away from the rotation locking groove 311 when sliding in the opposite direction of the first direction P1, in one embodiment, a stopper is provided on the side of the transverse slider 431 facing away from the locking handle 30. A first return member 42 is connected between the housing 20 and the stopper. The vertical sliding assembly 432 is capable of forcing the transverse slider 431 to move in the opposite direction of the first direction P1 to abut against the stopper, and, through the stopper, drives the locking pin 41 in the opposite direction of the first direction P1 to disengage the rotation locking groove 311. Specifically, the transverse slider 431 defines a through hole in the first direction P1, through which the locking pin 41 can slide relative to the through hole. The radial dimension of the stopper is larger than that of the through hole. When the locking handle 30 is at a first rotation angle, a sliding gap exists between the stopper and the transverse slider 431 in the first direction P1. Therefore, when the locking handle 30 is rotated to a second rotation angle, the locking pin 41 has room to move in the first direction P1 to engage the rotation locking groove 311.

[0034] Furthermore, the vertical sliding assembly 432 includes a transmission block 4321 and a vertical return member 4322. The vertical return member 4322 can be a compression spring or a magnetic member. For example, if the vertical return member 4322 is a compression spring, the vertical return member 4322 is connected between the transmission block 4321 and the housing 20. The vertical return member 4322 is used to drive the transmission block 4321 to slide in the opposite direction of the second direction P2. The transmission block 4321 is transmission-connected to the transverse slider 431. The transmission connection can be implemented in various ways, as long as the transmission block 4321 can drive the transverse slider 431 to move in the opposite direction of the first direction P1 when moving in the opposite direction of the second direction P2. In one embodiment, the transverse slider 431 has a first inclined surface 4311, and the transmission block 4321 has a second inclined surface 4321a. The first inclined surface 4311 and the second inclined surface 4321a are parallel to each other and abut against each other, and are inclined relative to the first direction P1 and the second direction P2. In this way, the inclined surface structure can transmit force in the vertical direction. Specifically, an inclined guide groove 4312 can be opened in the horizontal slider 431, and the guide groove 4312 is inclined relative to the first direction P1 and the second direction P2. A guide rod 4321b is provided on the transmission block 4321, and the guide rod 4321b can be slidably passed through the guide groove 4312. The opposite side surfaces of the guide rod 4321b in the first direction P1 are the second inclined surfaces 4321a, and the opposite groove surfaces of the guide groove 4312 in the first direction P1 are the first inclined surfaces 4311.

[0035] See Figure 1 The lighting device according to the second embodiment of the present invention includes a lamp body 60, a bracket 70, and the easily removable device 10 of any of the above embodiments. The lamp body 60 is fixed to the housing 20. The bracket 70 is provided with a mounting member 71. The mounting member 71 has a buckle slot. The buckle engages the buckle slot, and the mounting member 71 is clamped between the second reset member 43 and the buckle. This embodiment has all the beneficial effects brought about by the first embodiment. When the easily removable device 10 is not initially assembled with the mounting member 71 on the bracket 70, the locking handle 30 maintains its initial angle under the action of the rotary reset member 50, and the rotating handle is tightly against the housing 20. At this time, the lock buckle on the locking handle 30 extends from the first avoidance opening to the limiting groove, and the transmission block 4321 is moved to the maximum movable distance in the opposite direction of the second direction P2 by the elastic force of the vertical reset member 4322. The supporting portion 4321c is located in the limiting groove, and the transmission block 4321 simultaneously drives the horizontal slider 431 to move to the maximum movable distance in the opposite direction of the first direction P1. At the same time, the horizontal slider 431 moves against the limiting portion, causing the locking pin 41 to also move in the opposite direction of the first direction P1. At this time, the locking pin 41 is disengaged from the rotating locking groove 311 and is not in contact with the locking handle 30.

[0036] When the mounting member 71 is installed, the mounting member 71 gradually inserts into the limiting groove, pushing the lock catch into the first escape opening, and the locking handle 30 rotates accordingly. When the locking groove on the mounting member 71 is aligned with the first escape opening, the lock catch rotates under the action of the rotation reset member 50 to re-extend the first escape opening and snap into the locking groove. During this process, the mounting member 71 also pushes the supporting portion 4321c into the second escape opening along the second direction P2. When the transmission block 4321 moves along the second direction P2, it also drives the transverse slider 431 to move along the first direction P1 to approach the locking handle 30. At this time, the locking pin 41, under the action of the first reset member 42, can move closer to the locking handle 30 and abut against the abutting curved surface 31. When it is necessary to remove the mounting member 71, the locking handle 30 is further rotated from the first rotation angle to the second rotation angle. During this process, the locking pin 41 slides on the abutting curved surface 31 and finally gets stuck in it when it is facing the rotation locking groove 311, thereby limiting the rotation of the locking handle 30. At the same time, the lock buckle in this state is also retracted into the first avoidance opening again, so that the lock buckle can be disengaged from the mounting member 71 and lock the angle of the locking handle 30, so that the lock buckle will not rotate and re-lock into the mounting member 71 before the user removes the mounting member 71 from the shell 20, thereby facilitating the removal of the mounting member 71.

[0037] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
