Detailed Description
The invention is further described below with reference to the drawings and detailed description.
Referring to fig. 1-10, the present embodiment depicts a lamp comprising a lamp tube 20 and an automatic lamp tube fixing device 10, the automatic lamp tube fixing device 10 being mounted on a lamp holder 30. In this embodiment, when the lamp tube 20 is not installed in the lamp tube fixing device 10, the automatic fixing device 10 is in an open state, as shown in fig. 1, the clamping block 11 is opened outwards, and the movable block 12 protrudes upwards; when the lamp 20 is mounted on the automatic lamp fixing device 10, the lamp 20 presses down the upper end of the movable block 12, the clamping block 11 is closed inwards to clamp the lamp, and the automatic lamp fixing device 10 is changed into a closed state, as shown in fig. 2, and the lamp mounting is completed.
In order to achieve the above-mentioned installation effect, in this embodiment, the automatic lamp tube fixing device 10 specifically includes: the clamping block 11, the movable block 12 and the reversing mechanism are connected between the clamping block 11 and the movable block 12; the upper surface of the base 13 is an opening surface, the movable block 12 is arranged at the opening surface, and the clamping block 11 enters the base 13 through the opening surface and is connected with the movable block 12 through the reversing mechanism.
The movable block 12 is pressed by the lamp tube to move downwards along the vertical direction, and the reversing mechanism converts the downward movement of the movable block 12 along the vertical direction into the rotation of the clamping block 11 around the fixed pivot, so that the clamping block 11 rotates between the releasing position and the clamping position to change the clamping space surrounded by the clamping block 11. Therefore, when the lamp tube 20 is not installed, the movable block 12 is in an upward protruding state, the clamping space enclosed between the two clamping blocks 11 is relatively large, and when the lamp tube 20 drives the movable block 12 to press down, the clamping blocks 11 rotate around the fixed pivot, so that the clamping space enclosed between the two clamping blocks 11 is small, and clamping of the clamping blocks 11 to the outer wall of the lamp tube 20 is realized.
In this embodiment, two clamping blocks 11 are provided, and the reversing mechanism is a connecting rod 16. The lower end of the connecting rod 16 is rotationally connected with the lower end of the clamping block 11, and the upper end of the connecting rod 16 is rotationally connected with the lower end of the movable block 12. The fixed fulcrum is arranged between the upper end and the lower end of the clamping block 11.
Specifically, the clamping block 11 includes a circular arc section 111 with an arc adapted to the arc of the lamp 20, so as to clamp the outer wall of the lamp 20. The end of the clamping block far away from the arc section 111 is also provided with a buckle protruding shaft 113 for forming a rotary connection with the lower end of the connecting rod 16.
In addition, the clamping block 11 is provided with a circular protruding shaft 112 between the circular arc section 111 and the clamping protruding shaft 113. The inner wall of the base 13 is also provided with a round hole 131 for fixing the round protruding shaft 112, and the round protruding shaft 112 forms a central shaft in the opening and closing movement of the clamping block 11.
The upper surface of the movable block 12 has a concave arc surface 121, which corresponds to the arc of the outer wall of the lamp tube 20, so that the contact area between the lamp tube 20 and the movable block 12 is maximized when the lamp tube 20 is pressed down, the pressure applied to the lamp tube 2 is reduced, and the lamp tube 20 is prevented from being broken. The movable block 12 has two convex snap-fit protruding shafts 122 along the thickness direction, and two snap-fit protruding shafts 122 are provided on each side for connecting with the connecting rod 16 to form a rotational connection.
In addition, for mounting the movable block 12, a support is provided below the movable block 12, which extends into the base 13 from the opening surface. In order to control the displacement of the movable block 12 along the vertical direction in an up-and-down motion so as to enable the movable block to reliably work, a sliding groove 123 arranged along the vertical direction is arranged on the support, and a limiting block 132 is arranged on the inner surface of the back plate 15 of the base 13; the limiting block 132 is disposed in the sliding groove 123, and when the support moves downward or upward along the vertical direction, the base 13 is stationary, so that the sliding groove 123 and the limiting block 132 move relatively, and the limiting block 132 can limit the maximum displacement of the support upward or downward.
When the clamping block 11 clamps the lamp tube 20, the lamp tube 20 needs to be fixed at the clamping position, and therefore, the lamp tube clamping device further comprises a fixing mechanism for fixing the clamping block 11 at the clamping position; the fixing mechanism is in limiting connection with the clamping block 11 along the vertical direction.
Specifically, the fixing mechanism comprises a movable bar 14 arranged below the support of the movable block 12, wherein the movable bar 14 extends along the horizontal direction, and the tail end of the movable bar is bent upwards along the vertical direction to form a fixed block 143;
A yielding opening 124 is formed through the bottom surface of the support; the movable bar 14 is also abutted against the first return spring 18, the initial position of the fixed block 143 is staggered from the yielding opening 124, and the side of the fixed block 143 facing the support is an inclined plane.
When the movable block 12 drives the support to move downwards, the bottom surface of the support abuts against the inclined surface of the fixed block 143, so that the movable bar 14 is driven to move along the horizontal direction, and meanwhile, the first return spring 18 is pressed to accumulate elastic return force. When the movable bar moves to the position corresponding to the position of the yielding opening 124 and the position corresponding to the fixed block 143, the fixed block 143 enters the yielding opening 124, and the first return spring 18 releases the elastic return force, so that the bottom surfaces of the fixed block 143 and the support are clamped and limited along the vertical direction. Thus, the movable block 12 is fixed at the current position, so that the clamping block 11 can be always in the clamping state.
In order to cooperate with the above structure, the base 13 is provided with a mounting groove at a position close to the left and right side walls, the first return spring 18 is disposed in the mounting groove, one side of the mounting groove facing the central axis of the base is provided with a yielding opening, and the movable strip 14 passes through the first return spring 18 and the yielding opening.
In daily use, the lamp 20 is damaged and needs to be replaced, and the clamping block 11 needs to be manually restored to the releasing position, so that the embodiment further includes a releasing and fixing mechanism, which is arranged in linkage with the movable strip 14, and drives the movable strip 14 to move along the horizontal direction, so that the fixing block 143 is moved out of the yielding opening 124. Specifically, the touch fixing means is a button 141, and both left and right side walls of the base 13 are respectively provided with a through opening through which the button 141 is exposed to the outside of the base 13. When in use, a user can drive the movable bar 14 to move along the horizontal direction only by pressing the button 141, and then the fixed block 143 is moved out of the yielding opening 124.
Finally, only the fixed block 143 is moved out of the yielding opening 124, and the movable block 12 can not be driven to reset by the support, so that a second reset spring 17 is required to be arranged, the lower end of the second reset spring is a fixed end, and the upper end of the second reset spring is abutted with the support; when the support moves downwards in the vertical direction, said second return spring 17 is pressed to accumulate an elastic return force.
The automatic lamp tube fixing device realizes high automation of lamp tube installation and disassembly; when the lamp tube is installed, the lamp tube is placed into the fixing device, and the fixing device can automatically clamp the lamp tube; when the lamp tube is disassembled, buttons on two sides of the fixing device are pressed, the lamp tube is automatically ejected, and the risk of falling off caused by mistaken touch of the lamp tube is prevented.
The foregoing is merely illustrative of the preferred embodiments of the present invention and is not intended to limit the scope of the invention. Equivalent changes and modifications are intended to be covered by this invention, as equivalents will fall within the scope of the invention.
