Description

Technical Field

[0001] The invention relates to the technical field of filament adjustment, in particular to a filament adjustment device on a wick. Background Art

[0002] The wick is a component in the light source. Its working principle is mainly to concentrate the light in a small area, so as to concentrate the light and increase the lighting intensity, which is convenient for work and study. It is an element used in conjunction with the wick in the filament light source.

[0003] As shown in the published patent, patent number: CN202121309068.X, patent name: A LED filament core column for adjustable color temperature, four groups of filament assemblies are set in this patent. By adjusting the four groups of filament assemblies, the defects caused by the fixed relative position and relatively fixed illumination range of the filaments in the traditional light source are solved. In the above patent, when adjusting the filaments, the four filaments need to be adjusted one by one. This adjustment method is extremely inconvenient. After each adjustment of a filament, the component needs to be rotated. After the personnel restores the ideal position for operation, the next filament is adjusted.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention can adjust the two filaments at the same time by cooperating with the main shaft, gear 2 and gear 3 and other structures, by controlling the two conductive blocks 1 at the same time, until the two filaments are adjusted to achieve better aesthetics and lighting effects as required;

[0025] At the same time, the adjustment method requires pressing the driving knob downward first. This process avoids the possibility of inconvenient operation caused by accidental touching of the component, and the size of gear two is smaller than gear one. At the same time, when the personnel drives the driving knob, the circular path of rotation at the edge of the driving knob is longer, so that the personnel need to rotate a relatively large displacement path, so that the conductive block one can be displaced relatively small. This can make the adjustment process more precise and the practical effect better.

[0026] Second, the present invention cooperates with the triangular block, the piston rod and the connecting shaft, so that during the adjustment process, the operator does not need to deliberately keep pressing the driving knob after pressing the driving knob, that is, the adjustment operation can be performed without applying much external force, which is more convenient and practical;

[0027] At the same time, this method allows the control of the locking rod and the control of the driving torque to be at the same position. In actual operation, personnel can drive and unlock the structure with three fingers. It is easy to use and can free the auxiliary hand for other operations, further improving its practicality.

[0028] 3. The present invention locks the expansion adjustment of the filament by rotating the driving torque in the positive direction through the cooperation of structures such as a micro motor, a threaded rod and a displacement frame. When the device is in use, personnel can directly use it as usual. If the target needs to be adjusted, they can directly switch. Compared with some traditional methods that require first twisting in one direction and then continuing forward or reverse rotation based on the actual movement situation, this method does not require trial and error, and its practicality is further improved. Novices can also quickly become familiar with the operation.

[0029] Fourth, the present invention can physically cut off the circuit of the filament before adjusting the position of the filament, thereby avoiding the situation in which the circuit switch gate is forgotten to be closed during the work process of maintenance and adjustment, and is accidentally opened by other staff, causing the filament to be energized, thereby affecting the safety of the filament adjustment process;

[0030] At the same time, the locking property of the triangular block also allows the circuit breaker state to be maintained continuously during maintenance and adjustment without the need for additional attention, further improving the overall practicality of the equipment.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] See also Figures 1 to 9The present invention provides a technical solution: a filament adjustment device on a wick, comprising a wick column 1 and four groups of filaments 2, and also comprising a bottom plate 3, the surface of the wick column 1 is fixedly connected to two sleeves 4, the inner walls of the two sleeves 4 are respectively fixedly connected to an upper bracket 5 and a lower bracket 6, the upper bracket 5 is divided into two parts, the left and right parts, and the upper bracket 5 is connected to a power-on state through a power-off component;

[0045] The upper bracket 5 and the lower bracket 6 are connected to the four groups of filaments 2 through four groups of connecting components. The connecting components include a conductive block 7 slidably connected to the upper bracket 5 and a conductive block 8 fixedly connected to the lower bracket 6. A displacement frame 9 is provided below the bottom plate 3.

[0046] It also includes an adjusting component for driving the conductive blocks 7 to slide along the outer wall of the upper bracket 5 in groups of two;

[0047] A locking component, which is in driving connection with the adjusting component to lock the adjusted position of the conductive block 7;

[0048] The transfer component is transmission-connected with the adjustment component so as to change the operation of the adjustment component by moving the displacement frame 9.

[0049] More specifically, in this embodiment: when the component is used for the first time, four groups of filaments 2 are installed on the component through connecting components so as to be electrically connected to the wick column 1, and a closed circuit is formed through the upper bracket 5 and the lower bracket 6, and then the bottom plate 3 is fixedly installed in the desired position and it can be powered on for use. If adjustment is required, the four conductive blocks 7 can be controlled by adjusting components so that two of them are grouped together and slide along the outer wall of the upper bracket 5. During the sliding of the four conductive blocks 7, the relative spacing distances of the four groups of filaments 2 can be changed through the connecting components, so that the aesthetics and illumination effects can be adjusted as needed. After the adjustment is completed, the position of the conductive block 7 is locked by the locking component so that the adjusted position will not change. In the process of adjustment, the transfer component can be controlled in advance to change the spatial position of the displacement frame 9 to replace the target of the conductive block 7 during the operation of the adjustment component.

[0050] It is worth noting that the bottom plate 3 can be installed on the outer shell, and in the operation of the structure, it can be regarded as a fixed base for reference, and the upper bracket 5 can maintain a fixed power-on state by setting the power-off component.

[0051] Embodiment 2, based on the above embodiment:

[0052] See also Figures 1 to 5The connecting components in the first embodiment are disclosed as follows. The connecting components include: two welding wires 10, which are respectively arranged at the two ends of the filament 2, and the surfaces of the conductive block 1 7 and the conductive block 2 8 are fixedly connected with welding parts 11, and the two welding wires 10 pass through the two welding parts 11 respectively.

[0053] More specifically, in this embodiment: two welding wires 10 are passed through the upper and lower welding pieces 11 respectively, and then tightened by conductive bolts, so that the initial installation process of the filament 2 is achieved by fixing the two welding wires 10 .

[0054] Embodiment 3, based on the above embodiment:

[0055] See also Figures 1 to 9 , the adjusting component in the first embodiment is disclosed as follows, the adjusting component comprises: a main shaft 12, the shaft arm of the main shaft 12 is rotatably connected to the inner wall of the bottom plate 3, the shaft arm of the main shaft 12 is fixedly connected to a gear 13, the surface of the bottom plate 3 is fixedly connected to a connecting tube 14, the inner wall of the connecting tube 14 and the inner wall of the bottom plate 3 are jointly sleeved with a fixed shaft 15, the shaft arm of the fixed shaft 15 is fixedly connected to a gear 2 16, the shaft arm of the fixed shaft 15 is fixedly connected to a driving torque 17, the surface of the bottom plate 3 is fixedly connected to an adjusting spring 18, the end of the adjusting spring 18 is in contact with the surface of the gear 2 16, the teeth of the gear 2 16 are intermittently meshed with the teeth of the gear 1 13, the inner wall of the driving torque 17 is fixedly connected to a limit block group 19, and the limit block group 19 is meshed with the teeth of the gear 1 13;

[0056] The shaft arm of the main shaft 12 is fixedly connected with a gear three 20, and the surface of the base plate 3 is provided with two slide grooves, and the groove walls of the two slide grooves are slidably connected with sliders 21, and the surfaces of the two sliders 21 are fixedly connected with fitting springs 22, and the ends of the two fitting springs 22 are respectively slidably connected with the groove walls of the two slide grooves, and the inner walls of the two sliders 21 are embedded with magnets 23, and the groove walls of the two slide grooves are embedded with electromagnets 24. The surface of the base plate 3 is provided with two displacement grooves, and the groove walls of the two displacement grooves are slidably connected with slide plates 25. The surface of any slide plate 25 is rotatably connected with two threaded rods 26, and the inner wall of the displacement frame 9 is provided with two threaded openings for the two threaded rods 26 to pass through and be threadedly connected thereto, and the inner wall of the displacement frame 9 is fixedly connected with a rack one 27 and a rack two 28, and the surface of the slider 21 is rotatably connected with two hinged rods 29, and the two hinged rods 29 are respectively insulated and rotatably connected to the surfaces of the two conductive blocks one 7.

[0057] More specifically, in this embodiment: the driving knob 17 can be pressed first to displace the driving knob downward, pushing the limit block group 19 to move downward synchronously, so that the limit block group 19 is first disengaged from the teeth of the gear 13, and at the same time, in the process of the driving knob 17 moving downward, the fixed shaft 15 is synchronously driven to move downward, and the fixed shaft 15 is moved downward, so that the gear 2 16 is displaced downward by the downward movement of the fixed shaft 15, so that the teeth of the gear 2 16 are meshed with the teeth of the gear 13, and then the personnel rotate the driving knob 17 while maintaining this state, and the rotation of the driving knob 17 synchronously drives the gear 2 16 to rotate, so that the gear 13 is synchronously driven to rotate by the rotation of the gear 2 16, so that the main shaft 12 can be rotated by the rotation of the gear 13, and then the main shaft 12 can be rotated by the rotation of the main shaft 12, and then the main shaft 12 can be rotated by the rotation of the main shaft 12. The rotation of the shaft 12 causes the gear 3 20 to rotate. The rotation of the gear 3 20 can cause the rack 2 28 meshing with it to be displaced, so that the displacement frame 9 can be displaced horizontally. The horizontal displacement of the displacement frame 9 will push the slider 21 on one side, so that the slider 21 on one side slides along the groove wall of the slide groove, and the matching fitting spring 22 is compressed. At this time, the slider 21 on the other side is separated from the surface of the displacement frame 9. During the displacement of the slider 21 on this side, the two conductive blocks 7 can be synchronously pushed through the transmission of the two hinged rods 29, so that the two conductive blocks 7 can synchronously slide along the surface of the upper bracket 5. In this way, the position of the connected filament 2 can be changed by the change in the position of the two conductive blocks 7.

[0058] After the adjustment is completed, the corresponding electromagnet 24 is energized to generate attraction for the magnet 23, thereby limiting this state. When the other side is subsequently adjusted, the displacement frame 9 and the slider 21 are normally out of contact.

[0059] In this way, the two filaments 2 can be adjusted at the same time by controlling the two conductive blocks 7 at the same time until they are adjusted to a better aesthetic and illumination effect as needed. At the same time, when driving the conductive block 7 to move, it is necessary to first press the driving knob 17 downward. This process avoids the possibility of inconvenience caused by accidental touching of the components. At the same time, the displacement of the driving rack 28 is formed by driving the gear 2 16 to drive the gear 13 to rotate. It can be seen from the figure that the size of the gear 2 16 is smaller than the gear 13. At the same time, when the personnel drives the driving knob 17, the circumference of the driving knob 17 is larger. It can be seen that the personnel need to rotate a larger displacement path to make the conductive block 7 move with a smaller amplitude. This can make the adjustment process more refined and the practical effect better.

[0060] Embodiment 4, based on the above embodiment:

[0061] See also Figures 2 to 7The locking component in the first embodiment is disclosed as follows. The locking component includes: a triangular block 30, a connecting rod 31 is fixedly connected to the surface of the triangular block 30, a locking rod 32 is slidably connected to the inner wall of the fixed shaft 15 and the driving torque 17, the rod wall of the locking rod 32 is provided with an oblique groove 33, the rod wall of the connecting rod 31 is fixedly connected to a connecting shaft 34, the shaft arm of the connecting shaft 34 is slidably connected to the groove wall of the oblique groove 33, the inner wall of the connecting rod 31 is slidably connected to a piston rod 35, the end of the piston rod 35 is fixedly connected to the inner wall of the fixed shaft 15, the rod wall of the piston rod 35 is sleeved with an auxiliary spring 36, and the two ends of the auxiliary spring 36 are respectively fixedly connected to the inner wall of the fixed shaft 15 and the end of the connecting rod 31.

[0062] More specifically, in the present embodiment, during the downward displacement of the fixed shaft 15, the piston rod 35 is synchronously driven to move downward. The downward displacement of the piston rod 35 can cause the connecting rod 31 and the triangular block 30 to move downward synchronously, that is, the triangular block 30 moves downward synchronously with the fixed shaft 15. At this time, the locking rod 32 moves downward accordingly. As the triangular block 30 moves downward, when its inclined surface contacts the connecting cylinder 14, the outer wall of the connecting cylinder 14 presses the triangular block 30, so that the triangular block 30 continues to move downward, squeezing the auxiliary spring 36 until the triangular block 30 moves to the cavity in the connecting cylinder 14. It pops up quickly under the elastic action of the spring 36, and the horizontal edge of the triangular block 30 fits the inner wall of the cavity, so that the fixed axis 15 cannot move up independently. In this state, gear 2 16 is meshed with gear 1 13, and then the personnel can drive it in rotation. During rotation, the triangular block 30 slides along the inner wall of the cavity. When unlocking is required, the personnel actively presses the locking rod 32, so that the locking rod 32 and the fixed axis 15 are displaced relative to each other, so that the connecting shaft 34 is displaced along the groove wall of the inclined groove 33, and then the connecting rod 31 actively compresses the auxiliary spring 36, so that the triangular block 30 is detached from the cavity, and then the structure is reset.

[0063] Through the above method, during the adjustment process, the personnel can first press the driving knob 17 downward. Since the adjustment spring is compressed at this time, the triangular block 30 can be used to prevent the subsequent personnel from deliberately keeping the driving knob 17 pressed during the rotation of the driving knob 17, that is, there is no need to apply more external force, making the operation more convenient and practical. At the same time, by adopting this method, the control of the locking rod 32 and the control of the driving knob 17 are at the same position. In actual operation, the personnel can realize the structure driving and unlocking operations with three fingers, which is easy to use and can free the auxiliary hand for other operations, and is highly practical.

[0064] Embodiment 5, based on the above embodiment:

[0065] See also Figure 5 and Figure 6The transfer component in Example 1 is disclosed as follows. The transfer component includes: two micro motors 37, both of which are fixedly connected to the surface of the slide plate 25 away from the threaded rod 26, and the output ends of the two micro motors 37 are fixedly connected to the ends of the two threaded rods 26 respectively.

[0066] More specifically, in this embodiment: by starting two micro motors 37, the two threaded rods 26 can be synchronously driven to rotate by the two micro motors 37, so that the displacement frame 9 can be displaced, so that the teeth of the rack 2 28 are disengaged from the gear 3 20, and the teeth of the rack 1 27 are meshed with the gear 3 20. In this way, by changing the meshing relationship, the two groups of filaments 2 on both sides can be controlled and adjusted separately when the gear 3 20 rotates in the same direction.

[0067] By adopting the above method, the corresponding state of the single-direction rotating driving knob 17 is to adjust the expansion of one of the groups of filaments 2 on the two sides. In this way, the adjustment method of the expansion adjustment can be locked as the positive direction rotation of the driving knob 17, and the contraction adjustment of the group of filaments 2 on the target side can be locked as the reverse direction rotation of the driving knob 17. In this way, the rotation direction of the driving knob 17 can be specified, so that when the equipment is in use, personnel can directly use it as usual, and can directly switch if they need to adjust the target. Compared with some traditional methods, when it is necessary to control the filament 2 targets on both sides separately, it is necessary to change the rotation direction of the driving knob 17 accordingly, so that when using it, personnel often need to twist it in one direction first, and then continue to rotate forward or reverse according to the actual movement situation. Compared with the traditional method, this method does not require trial, and its practicality is further improved, and novices can also be familiar with the operation.

[0068] Embodiment 6, based on the above embodiment:

[0069] See also Figure 1 , the components in the first embodiment are disclosed as follows: the outer wall of the driving knob 17 is provided with friction lines, and the top surface of the driving knob 17 is provided with two locking switches 38, and the two locking switches 38 are respectively connected to the two electromagnets 24 by electrical signals.

[0070] More specifically, in this embodiment, the friction lines are provided to prevent a person from slipping when twisting, and the locking switch 38 can control the power-on state of the electromagnet 24 .

[0071] Embodiment 7, based on the above embodiment:

[0072] See also Figures 1 to 9 , the components in the first embodiment are disclosed as follows: the sizes of the rack 1 27 and the rack 2 28 are both adapted to the size of the gear 3 20, and the rack 1 27 and the rack 2 28 are symmetrically arranged.

[0073] More specifically, in this embodiment, by limiting the sizes of rack 1 27, rack 2 28 and gear 3 20, the structure can smoothly maintain the process of disengagement and re-engagement during operation.

[0074] Embodiment 8, based on the above embodiment:

[0075] See also Figure 8 , the components in the first embodiment are disclosed as follows: the inner walls of the four conductive blocks 7 are provided with conductive balls, and the surfaces of the four groups of conductive balls are all in contact with the surface of the upper bracket 5.

[0076] More specifically, in this embodiment, the conductive balls are arranged so that the electric block 7 can move more smoothly on the upper bracket 5.

[0077] Embodiment 9, based on the above embodiment:

[0078] See also Figure 1 , Figure 2 and Fig.10 The power-off component in the first embodiment is disclosed as follows: the power-off component includes an insulating frame 40, a connecting groove is formed on the upper sleeve 4 and the inner wall of the wick column 1, the insulating frame 40 is slidably connected to the groove wall of the connecting groove, the surface of the insulating frame 40 is connected to the inner wall of the connecting groove through a power-off spring 41, a power-on plate 42 and an insulating plate 43 are embedded in the insulating frame 40, a push rod 39 is fixedly connected to the top surface of the insulating frame 40, the push rod 39 passes through the main shaft 12, and the end of the push rod 39 is in contact with the inner wall of the driving torque 17.

[0079] More specifically, in this embodiment: when the device is in normal use, the power-on plate 42 is located at the connection of the upper bracket 5. At this time, the upper bracket 5 maintains a circuit connection state. During the adjustment and the process of pressing the driving knob 17, the push rod 39 is synchronously pushed to move, so that the push rod 39 slides downward along the inner wall of the main shaft 12. At the same time, the push rod 39 moves downward, pushing the insulating frame 40 to move downward, squeezing the power-off spring 41. At the same time, the insulating frame 40 moves downward, so that the power-on plate 42 and the cross section of the upper bracket 5 are separated from each other, and the insulating plate 43 is replaced by the cross section of the upper bracket 5. In this way, the upper bracket 5 is kept in a power-off state through the insulating plate 43, so that in the subsequent adjustment process, the four groups of filaments 2 are kept in a power-off state;

[0080] By adopting this approach, during the adjustment process, the circuit of the filament 2 can be physically cut off before adjusting the position of the filament 2, thereby avoiding the situation in which the circuit switch gate is forgotten to be closed and is accidentally opened by other staff during the maintenance and adjustment process, causing the filament 2 to be energized, thereby affecting the safety of the filament 2 adjustment process. It is also worth noting that through the setting of the triangular block 30 in the above process, the power-off spring 41 can also be kept in a squeezed state, that is, during the maintenance and adjustment process, the circuit-breaking state can be maintained continuously without additional attention, so the overall practicality and safety are further improved.

[0081] Working principle: When the filament adjustment device on the wick is used, the four groups of filaments 2 are installed on the component through the connecting parts, so that they are electrically connected to the wick column 1, and a closed circuit is formed through the upper bracket 5 and the lower bracket 6. Then the bottom plate 3 is fixedly installed at the required position and it can be powered on for use. If adjustment is required, the driving knob 17 can be pressed first to make the limit block group 19 disengage from the teeth of the gear 13 first, and then the driving knob 17 is rotated to make the four conductive blocks 7 slide along the outer wall of the upper bracket 5 in groups of two. During the sliding of the four conductive blocks 7, the relative spacing distances of the four groups of filaments 2 can be changed through the connecting parts, so that the aesthetics and illumination effect can be adjusted as needed. After the adjustment is completed, the position of the conductive block 7 is locked by the locking component so that the adjusted position will not change. In the process of adjustment, the micro motor 37 can be started in advance to adjust the other group of the two groups on both sides in the form of changing the spatial position of the displacement frame 9.
