The following is a description of the embodiments of the present invention by specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied by other different specific examples. Various details in the description of the present invention can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention.

The present invention is a wire-retracting structure for operation wires, mainly for a group of loop-shaped operation wires, and provides two modes of double wire pulling or single wire pulling. It will brake synchronously after the double wire is pulled out. Then change to the single-wire pull mode to operate the matched mechanical structure. In addition, when pulled by the double wire again, the operation wire can be pulled back and hidden. The wire take-up structure of the present invention can be widely used in mechanical lift units used in projectors, lamp carriers, drying racks, hidden storage cabinets, etc. In this way, it provides a take-up structure that can be automatically collected and pulled out without electricity.

As shown in Figure 1, it is a perspective view of the present invention. The wire-receiving structure of the operation wire of the present invention includes a carrier board 1 and a main driving wheel 2 mounted thereon, a wire pulling unit 3, a brake unit 4, and an operation wire 5. The carrier board 1 is provided with at least one guide wheel 11 and at least one outlet hole 12 (as shown in FIG. 3 ). The operation wire 5 is a closed winding, which is sheathed on the periphery of the main driving wheel 2, and the remaining wire segments pass through the wire drawing unit 3, the braking unit 4, the guide wheel 11, and finally through the wire outlet hole 12 Extend to the outside world. The cable unit 3 includes a fixed The component 31, at least one cable holder 32 and at least one spring 33. The wire-drawing frame 32 can move toward or away from the fixing member 31. The spring 33 is connected to the cable support 32 to provide a home power. Several first guide wheels 311 are provided on the fixing member 31. Several second guide wheels 321 are provided on the wire pulling frame 32. The single line segment of the operation wire 5 surrounds the first guide wheel 311 and the second guide wheel 321 in sequence. By the offset of the cable holder 32 away from the fixing member 31, the length of the operation wire 5 around it is increased. The brake unit 4 can be fully pulled after the operation wire 5 is double-wired. When pulling again, the push wheel 44 can be pulled. The cable holder 32 can be clamped when it is close to the fixing member 31 (as shown in FIG. 2 ). Subsequently, the operation wire 5 can be pulled in a single line and the main driving wheel 2 can be driven to rotate. After the single-line pulling action is performed, if the operation wire 5 is pulled by the double-line again, the locked state can be released. Pulling the cable holder 32 via a spring can return to the original position, so that the operation wire 5 is recovered and hidden on the carrier board 1 again.

Next, a detailed description will be given on the structure of each structure: the carrier board 1 is a large-area plate or a hollow casing for installing the main driving wheel 2, the cable unit 3 and the brake unit 4. The main driving wheel 2 is a power output wheel, which is coaxially connected with the external member to be rotated. When the operation wire 5 is pulled by a single wire, the main driving wheel 2 can be driven to rotate. In this embodiment, the main driving wheel 2 is mounted on the fixing member 31. As shown in FIG. 3, the number guide wheel 11 of the carrier board 1 is fixed to a wire guide frame 13. The two guide wheels 11 are connected in series for the operation line 5 to pass through and turn. Finally, the operation wire 5 extends through the outlet hole 12 to the lower space.

The wire pulling unit 3 includes a fixing member 31, at least one wire pulling frame 32 and at least one spring 33. In this embodiment, in order to make the operation more stable and increase the length of the take-up wire, the wire-drawing frame 32 is provided with two groups located on both sides of the fixing member 31. A plurality of first guide wheels 311 are provided on the fixing member 31 corresponding to each direction of the cable frame 32. The positions of the plurality of first guide wheels 311 correspond to the corresponding plurality of second guide wheels 321. The two line segments of the operation wire 5 respectively sequentially surround the first guide wheel 311 and the second guide wheel 321. The cable pulling unit 3 further includes at least one guide rod 34. The guide rod 34 is fixed to the fixing member 31 Side. Each of the wire-drawing frames 32 is provided with two guide rods 34 penetrating therethrough, and the guide rods 34 ensure that the wire-drawing frames 32 can move smoothly and linearly. One end of the spring 33 is fixed on the carrier board 1 and the other end is fixed on the cable holder 32 to provide the power for the cable holder 32 to return.

The braking unit 4 is responsible for fixing the position of the cable frame 32 when the cable frame 32 is close to the fixing member 31. The braking unit 4 includes a casing group 41, a blocking rod 42, a push cap 43 and a push wheel 44. The blocking rod 42 is installed on the casing group 41, and can be extended and retracted in a timely manner after braking. The push cap 43 is sleeved on the periphery of the other end of the casing group 41, and controls the timing of extending the blocking rod 42 in conjunction. The push wheel 44 is fixed to the side of the push cap 43. The line segment of the operation wire 5 passes through the wire pulling unit 3 and then first surrounds the push wheel 44 and then passes around the guide wheel 11 and turns to the exit. Since the position of the push wheel 44 is higher than that of the guide wheel 11, the operation wires 5 will not interfere with each other when winding. When the operation wire 5 is pulled in two lines, the guide wheel 11 and the main driving wheel 2 of the fixing member 31 are fixed. Therefore, when the double wire of the operation wire 5 is completely pulled out, the pushing wheel 44 is pulled in the direction of the guide wheel 11 together. Simultaneously push the push cap 43 to synchronize linear movement. When the push cap 43 is pushed, it will cyclically switch through the internal mechanism of the casing group 41 to let the blocking rod 42 extend or retract. And when the blocking rod 42 is extended, the cable frame 32 is clamped (as shown in FIG. 2 ).

In this embodiment, the braking unit 4 is provided with two groups, the positions of which correspond to the braking positions of the two sets of cable stays 32 on both sides of the fixing member 31. Two sets of the braking unit 4 are provided with two sets of push wheels 44 connected in series. A support rod 45 is provided on each side of the push wheel 44 to connect with the corresponding push cap 43. In addition, in order to ensure that the pushing wheel 44 can move smoothly linearly when being pulled by the operation wire 5, the carrier board 1 is provided with two sets of fixed carriages 46. A group of sliding frames 47 are further arranged between the fixed sliding frames 46. Two sets of push wheels 44 are installed in the sliding frame 47. The sliding frame 47 is restricted to linearly slide between the two fixed sliding frames 46.

In the present invention, the braking unit 41 adopts a cyclic switching mode. When the push cap 43 is pushed for the first time, the blocking rod 42 is pushed out and locked by interlocking with the internal mechanism. Then the push cap 43 was pushed again Move, the original card-holding state is released and the stopper 42 is retracted. This cycle switching operation can achieve the required braking purpose without the assistance of electricity.

Next, this structure will be described in detail. As shown in FIGS. 4 and 5, the casing group 41 further includes a front end fixing frame 411, a spring 412, a rear end fixing frame 413, a rotary pushing member 414, and an outer sleeve 415 Way to express the internal structure), an axial pushing member 416. Please also refer to FIG. 1, the front end fixing frame 411 is fixedly mounted on the carrier board 1, and restricts the moving direction and distance of the blocking bar 42. A bump 421 is provided on the periphery of the stop rod 42. The spring 412 is sleeved on the periphery of the front section of the stop rod 42 and is limited between the convex post 421 and the front end fixing frame 411. The rear end fixing frame 413 is mounted on the carrier board 1 to fix the outer sleeve 415. The rear section of the blocking rod 42 extends into the outer sleeve 415. The outer sleeve 415 is axially sequentially installed with the rotating pushing member 414 and the axial pushing member 416, wherein the blocking bar 42 is inserted into the rotating pushing member 414. The push cap 43 is sleeved on the periphery of the axial pushing member 416 and interlocks therewith. When the push cap 43 is pushed, the axial pushing member 416 is moved up and down. The axial pushing member 416 will rotate the rotating pushing member 414 at an appropriate timing, thereby clamping the inner wall of the outer sleeve 415, so that the blocking rod 42 is pushed out. Afterwards, the push cap 43 is pushed again to release the jamming state and the gear bar 42 is retracted.

The above-mentioned clamping principle and structure are as follows: the inner wall of the outer sleeve 415 has several sliding grooves 4151, several first positioning inclined surfaces 4152 and several second positioning inclined surfaces 4153. The first positioning inclined surface 4152 and the second positioning inclined surface 4153 are alternately distributed on the inner wall in a ring shape. The lowest position of the first positioning slope 4152 is connected to the sliding slot 4151. In addition, a slideway 4154 is further provided between two adjacent slideways 4151. The radial depth of the slideway 4154 is shallower than that of the slideway 4151. The axial pushing member 416 has helical teeth 4161 on the end surface of the tube, and lumps 4162 on the outer wall. After assembly, several protrusions 4162 will be located in the sliding groove 4151 and the sliding path 4154 to maintain the axial pushing member 416 to move axially in the outer sleeve 415. The outer wall of the rotary pushing member 414 There are several convex strips 4141. The end of the convex strip 4141 has a slope 4142. The radial dimension of the convex strip 4141 is close to that of the sliding slot 4151.

As shown in FIGS. 6A-6C, for ease of description, only the main component outer sleeve 415, the rotary pushing member 414, and the axial pushing member 416 are shown in the figure. As shown in FIG. 6A, in the unbrake state, the convex strip 4141 of the rotary pushing member 414 is located in the sliding groove 4151. A part of the protrusion 4162 of the axial pushing member 416 is also located in the sliding slot 4151. However, the radial depth of the protrusion 4162 in the sliding slot 4151 is relatively shallow. The oblique teeth 4161 are in contact with the oblique surface 4142. As shown in FIG. 6B, when the axial pushing member 416 is pushed axially, after the convex strip 4141 is withdrawn from the sliding groove 4151, the inclined teeth 4161 will contact the inclined surface 4142 to guide the rotating pushing member 416 rotates clockwise, the power source is the spring 412. As shown in FIG. 6C, when the external force applied to the axial pushing member 416 disappears, the inclined surface 4142 then contacts the second positioning inclined surface 4153. The rotary pusher 416 continues to rotate. As shown in FIG. 6D, the inclined surface 4142 is finally locked at the lowest position of the second positioning inclined surface 4153. Therefore, the rotating pushing member 414 is extended and locked, and the blocking bar 42 is relatively extended. Then, if you want to release the card status, see Figure 6E. When the axial pushing member 416 is pushed in again. With the use of the helical teeth 4161 in contact with the inclined surface 4142, the rotating pusher 416 is guided to rotate. After that, the inclined surface 4142 will then contact the first positioning inclined surface 4152. Finally, the protruding strip 4141 is slid into the sliding slot 4151 again, and the bar 42 will be retracted relatively. In this way, the purpose of cyclic switching braking can be achieved.

Next, a description will be given of the operation mode of the present invention. As shown in Fig. 1, it is a perspective view of the state of taking up the wire. The carrier board 1 can be installed at the position of the indoor ceiling. The wire frame 32 is away from the fixing member 31 to allow the wire segment of the operation wire 5 to sequentially wrap between the first guide wheel 311 and the second guide wheel 321. In this way, the operation wire 5 is hidden in the cable unit 3 on the carrier board 1 to prevent the operation wire 5 from being exposed and being mistakenly pulled by children, thereby increasing safety and beauty.

When the operation wire 5 is to be pulled by a single wire to drive the main driving wheel 2 to rotate, as shown in FIG. 2. First, the operation wire 5 double wire must be completely pulled out. When pulling the wire, the acting resistance due to the movement of the preset braking unit 4 is greater than the elastic force of the wire pulling unit 3 when the wire is taken up. Therefore, when the cable is pulled, the cable unit 3 with a small acting resistance will act before the brake unit 4. Therefore, the two pulling frames 32 will be pulled closer to the fixing member 31. However, the braking unit 4 is temporarily inactive. When the two are close together, the resistance of the cable unit 3 is greater than that of the brake unit 4. At this time, the operation wire 5 is continuously pulled by two wires, and the force will fall on the braking unit 4. Exercise card movements. This is the end state when the operation wire 5 is pulled out. At this time, the operation wire 5 can be pulled by a single wire to drive the main driving wheel 2 to rotate.

Afterwards, if you want to close the wire, pull the operation wire 5 in two wires again to release the locking state of the brake unit 4. Perform the wire take-up action of the wire pulling unit 3. As shown in Figure 1.

The wire take-up structure of the present invention can be widely used in various mechanical lifting groups to achieve the purpose of automatic wire take-up and single-line operation without electric power. One of these methods will be explained, but not limited to this method. The present invention describes an embodiment of a lifting unit applied to a lamp. If the general lamp needs to replace the bulb, it can only be done by setting up a ladder. The design of the present invention can solve this problem.

As shown in FIGS. 7 and 8, a lifting unit 6 is erected under the carrier board 1. A gear set 7 is provided between the carrier plate 1 and the lifting frame 6. The lifting unit 6 includes an upper frame plate 61, a bearing platform 62, two sets of scissor telescopic groups 63, and two sets of drive mechanisms 64. The carrying platform 62 is used for installing a lamp 8 there. The figure only shows a lamp 8 in a simple manner. The upper and lower ends of the two groups of the scissor telescopic group 63 are respectively installed at the upper frame 61 and the bearing platform 62. The driving mechanism 64 is installed on the bottom surface of the upper frame 61 and includes a screw 641 and a slider 642. The slider 642 is screwed to the screw 641. When the screw 642 rotates the slider 642, it will move up and down. The slider 642 is pivotally connected to one of the intersections of the scissor telescopic group 63 (see FIG. 9). The screw 641 is interlocked by the gear set 7. The gear set 7 includes a main gear 71, a reduction gear set 72, and a number of driven gears 73. The main gear 71 is coaxially connected to the main drive wheel 2. The slave gear 73 is coaxially connected to the screw 641. The main gear 7 can drive the two driven gears 73 to rotate in the same direction through the reduction gear set 72 in a synchronized and labor-saving manner. In this way, the operation wire 5 can be operated with a small force to drive the main driving wheel 2 to rotate, and the driving mechanism 64 can be driven to move through the gear set 7.

As shown in Figure 9. When the operation wire 5 is pulled in a single direction, the main driving wheel 2 is driven to rotate, and through the operation of the gear set 7, the driving mechanism 64 is driven in a labor-saving mode. The slider 642 descends to extend the scissor telescopic group 63. The carrier 62 can be lowered significantly. Allows the operator to easily replace the bulb of the lamp 8 on the carrier 62.

In the above embodiment, when the carrying table 62 is raised and stored, it will be flush with the indoor ceiling (the ceiling is not shown in the figure). The user can install a pull ring on the ceiling to connect with the operation wire 5. After the operation line 5 is stored. The ceiling will only see the pull ring and no lines, making the appearance more beautiful. The user can borrow the tool to pull down the pull ring. The operation wire 5 hidden in the cable unit 3 hidden on the carrier board 1 is pulled out, and then the lifting unit 6 is operated to move up and down. Of course, the piping design of the interior decoration can also be used so that the end of the operation line 5 after storage is located at the control panel of the wall, which is convenient for the user to pull out the operation line 5 at the wall.

As shown in FIG. 10, an operation method used for applying the structure of the present invention is provided. The brake unit, the wire pulling unit, the main driving wheel and the operation wire installed at the carrier board are used. The operation wire is a closed loop winding. The operation wire is stored on the carrier board by the wire pulling unit and only part of the section is exposed. The operation method includes: Step A101: pull down the double wires of the exposed section of the operation wire at the same time, so that the collection section of the operation wire is pulled out; Step A102: when the operation wire cannot be pulled, the brake The unit is clamped on the cable unit; Step A103: change the operation wire pulled by a single wire, and the operation wire drives the member to be linked; and Step A104: when the operation wire is pulled by the two wires at the same time again, the brake unit can release the card applied to the wire unit制status. The wire pulling unit resumes the wire take-up operation again, and pulls the operation wire back to be stored on the carrier board.

Wherein in step A103, where the operation wire is pulled by a single wire, the operation wire can be pulled clockwise or counterclockwise in a unidirectional single wire. The main driving wheel is driven to rotate by the operation wire. As mentioned in the previous paragraph, the main drive wheel can be used to drive a group of elevator components up or down.

In summary, the wire take-up structure of the present invention provides a power-free automatic wire take-up concealment. After the double wire is pulled out, it can be replaced by the single wire pulling operation design, which is widely used in various types of lifting units and meets the patent application requirements.
