Description

Wire take-up structure and operation method of operation wire

The present invention is the technical field of a wire take-up structure and operation method of an operating wire. It is a device that can pull out the loop operation wire and retract it to hide. After the two wires are pulled out synchronously, the pulled wire is fixed by the brake unit. Then you can switch to a single-wire pulling operation to operate the matched mechanical structure. After completing the mechanical structure of the operation. The brake unit can be released again, and the wire can be automatically taken up and hidden again to meet the design concept of no electricity but can be automatically taken up and hidden.

A small mechanical lift unit can be installed on the indoor ceiling to lower the hidden projector or shelf for use by the operator. Or lower the lamp installed here for users to replace the bulb. However, mechanical lifting units usually require a set of operating lines. The operation of the linkage mechanism inside the elevator unit is controlled by pulling the operating line to lower the carrier. The conventional mechanical lifting unit is not designed with a take-up device. In this way, you will see a looped operating line hanging down from the ceiling, which will not only destroy the original interior decoration beauty. If there are children in the family, they may have an accident around the neck due to their playfulness. Don’t be careful.

In order to solve the above-mentioned problems, the present invention provides a wire take-up structure and operation method of an operating wire. There is no need for power assistance, and it can be used after the two wires of the operating line are pulled out of the line segment. The internal mechanism brakes in time. Then the operating line can be pulled by a single line to operate the lifting unit to descend or ascend. When the operating line is pulled by the double line again, the brake state will be released, and the operating line will be automatically retracted and hidden. It is safe to use and will not affect the beauty of interior decoration.

Another object of the present invention is to provide a wire take-up structure with a wide range of applications, which can be applied to indoor lamps, projectors, and mechanical lifting units used in conjunction with hidden racks, and even applicable to lifting drying racks.

To achieve the above objective, the wire take-up structure of the operating wire of the present invention includes a carrier board and a brake unit, a wire pulling unit, a main driving wheel and an operating wire mounted on it. The carrier board is provided with at least one guide wheel and at least one outlet hole. The operating wire is a closed winding, which is sleeved and connected to the periphery of the driving wheel, and the remaining wire segments are sequentially extended to the outside through the wire pulling unit, the braking unit, the guide wheel, and finally through the wire outlet hole. The cable unit includes a fixing member, at least one cable frame and at least one spring. The cable frame can move toward or away from the fixing member. The spring is connected with the cable frame to provide power for returning. The fixing part is provided with a plurality of first guide wheels.

The braking unit can be pulled after the two wires of the operating wire are simultaneously pulled. When the cable frame is close to the fixing member, it is locked. Subsequently, the operating wire can be pulled by a single wire to drive the main driving wheel to rotate. When the operating wire is pulled by the double wires again, the braking state of the braking unit is released, and the spring pulls the wire frame away from the fixing member and performs synchronous wire take-up.

Furthermore, the operating method of the operating wire of the present invention mainly includes a brake unit, a wire pulling unit, a main driving wheel and an operating wire installed on a carrier board. The operating wire is a closed loop winding. The operating wire is stored on the carrier board by the wire pulling unit and only a part of it is exposed. The operation method includes: simultaneously pulling down the two wires of the exposed section of the operating wire, so that the storing section of the operating wire is pulled out. When the operating wire cannot be pulled, the wire pulling unit can be locked by the brake unit. Instead, a single wire pulls the operating wire, and the operating wire drives the component to be linked. When the operating wire is pulled by the two wires at the same time again, the braking unit can release the blocking state applied to the wire pulling unit. The wire pulling unit resumes the wire take-up action again to pull the operating wire back and store it on the carrier board.

In this embodiment, the wire pulling unit further includes at least one guide rod fixed on the side of the fixing member, and the guiding rod penetrates the wire pulling frame to ensure the moving track of the wire pulling frame. One end of the spring is fixed to the carrier board, and the other end is fixed to the wire frame. The spring provides power for the wire frame to return to an initial position away from the fixing member.

In this embodiment, the cable frame is provided with two groups and located at two sides of the fixing member, respectively. A plurality of first guide wheels are provided on the fixing member in the direction corresponding to each cable frame, and a plurality of the The first guide wheel corresponds to a plurality of the second guide wheels whose positions are matched.

In this embodiment, the main driving wheel is mounted on the carrier board. The main driving wheel is coaxially connected with the external member to be steered.

The operating wire is the driving single wire being pulled to operate the main driving wheel in a forward or reverse direction.

In this embodiment, the brake unit includes a casing group, a block bar, a push cap and a push wheel. The blocking rod is partially installed in the casing group. The push cap sleeve is placed on the periphery of the other end of the casing of the unit. The push wheel is installed on the side of the push cap. The operating line surrounds the push wheel. When the two wires of the operating wire are pulled, the push wheel and the push cap are drawn to move linearly. The push cap pushes the internal mechanism of the casing group to perform cyclic switching, which will cause the blocking bar to extend or retract, and the cable frame will be locked when extended.

In this embodiment, the casing group includes a front end fixing frame, a spring, a rear end fixing frame, a rotary pushing member, an outer tube, and an axial pushing member. The front end frame fixing frame is installed on the carrier plate to limit the moving direction and distance of the blocking bar. The gear bar is provided with a convex post on the periphery. The spring is sleeved on the periphery of the gear bar and is limited between the protruding column and the front end fixing frame. The rear end fixing frame fixes the outer sleeve. The blocking rod partially extends to the outer sleeve. The outer sleeve axially installs the rotary pushing member and the axial pushing member in sequence. The blocking rod is inserted into the rotary pushing part. The pushing cap is sleeved on the periphery of the axial pushing part. When the axial pushing member is pushed in the axial direction, the rotating pushing member will rotate to lock different positions on the inner wall of the outer sleeve, so that the stop rod is pushed out or retracted.

In this embodiment, the inner wall of the outer sleeve has several sliding grooves, several first positioning slopes and several second positioning slopes. The first locating slope and the second locating slope are circularly and staggeredly distributed on the inner wall, wherein the bottommost position of the first locating slope is connected with the sliding groove. In addition, the tube end surface of the axial pushing member has several helical teeth, and the outer wall has several convex blocks. The protruding block is located in the sliding groove to maintain the axial pushing member to be able to move axially in the outer sleeve.

When the axial pushing member is pushed, the inclined tooth is used to contact the inclined surface, and the inclined surface is cyclically guided to contact the first positioning inclined surface or the second inclined surface. When the protruding bar contacts the first positioning inclined surface, the protruding bar will be guided into the sliding groove, and the blocking rod will be partially retracted into the outer sleeve.

The following is a specific embodiment to illustrate the implementation of the present invention. Those familiar with the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied by other different specific examples, and various details in the specification 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 take-up structure for operating wires, mainly for a group of ring-shaped operating wires, providing two modes of double wire pulling or single wire pulling. It will brake synchronously after the two wires are pulled out. Then switch to the single-wire pull mode to operate the matched mechanical structure. In addition, when it is pulled by two lines again, the operating line can be pulled and hidden. The cable take-up structure of the present invention can be widely used in mechanical lifting units used in projectors, lamp carriers, drying racks, hidden storage cabinets and the like. In this way, a wire take-up structure that has no power but can be automatically stored and pulled out is provided.

Figure 1 is a perspective view of the present invention. The wire take-up structure of the operating wire of the present invention includes a carrier board 1 and a main driving wheel 2 mounted on it, a wire pulling unit 3, a braking unit 4, and an operating wire 5. The carrier 1 is provided with at least one guide wheel 11 and at least one outlet hole 12 (as shown in FIG. 3). The operating wire 5 is a closed winding, which is sheathed on the periphery of the driving wheel 2, and the remaining wire segments are sequentially extended through the wire pulling unit 3, the braking unit 4, the guide wheel 11, and finally through the outlet hole 12 To the outside world. The pulling unit 3 includes a fixing member 31, at least one pulling frame 32 and at least one spring 33. The cable frame 32 can move closer to or away from the fixing member 31. The spring 33 is connected to the cable frame 32 to provide power for returning. The fixing member 31 is provided with a plurality of first guide wheels 311. A number of second guide wheels 321 are provided on the cable frame 32. A single line segment of the operating wire 5 sequentially surrounds the first guide wheel 311 and the second guide wheel 321. Due to the offset of the cable frame 32 away from the fixing member 31, the length of the operating wire 5 around this area is increased. The brake unit 4 can be pulled after the double wire of the operating wire 5 is completely pulled. When pulling again, the push wheel 44 can be pulled. When the cable frame 32 is close to the fixing member 31, it can be locked (as shown in FIG. 2). Subsequently, the operating wire 5 can be pulled by a single wire and the main driving wheel 2 can be driven to rotate. After the single-wire pulling action is performed, if the operating wire 5 is pulled by the double-wire again, the jamming state can be released. The wire frame 32 can be returned to its original position after being pulled by the spring, so that the operating wire 5 is recovered and hidden on the carrier board 1 again.

Then a detailed description of the structure of each structure:

The carrier board 1 is a large-area plate, and can also be a hollow housing 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 operating wire 5 is pulled, 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 at an outlet guide frame 13. The two guide wheels 11 are connected in series for the two wires of the operating wire 5 to pass and turn. Finally, the operating wire 5 extends through the outlet hole 12 to the space below.

The pulling unit 3 includes a fixing member 31, at least one pulling frame 32 and at least one spring 33. In this embodiment, in order to operate more steadily and increase the length of the wire take-up, the wire puller 32 is provided with two groups located on both sides of the fixing member 31 respectively. 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 the first guide wheels 311 correspond to the corresponding plurality of the second guide wheels 321. The two line segments of the operating wire 5 respectively surround the first guide wheel 311 and the second guide wheel 321 in sequence. The cable unit 3 further includes at least one guide rod 34. The guide rod 34 is fixed to the side of the fixing member 31. Each of the cable racks 32 is provided with two guide rods 34 penetrating therethrough, and the guide rods 34 ensure that the cable rack 32 can move smoothly and linearly. One end of the spring 33 is fixed to the carrier board 1 and the other end is fixed to the wire frame 32 to provide the power of the wire frame 32 to reset.

The brake 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 brake unit 4 includes a casing group 41, a blocking bar 42, a push cap 43 and a push wheel 44. The blocking bar 42 is installed on the casing group 41, and can be extended and retracted in time after braking. The push cap 43 is sleeved on the periphery of the other end of the casing group 41, and the timing of extending the blocking bar 42 is continuously controlled. The push wheel 44 is fixed on the side of the push cap 43. The wire segment of the operating wire 5 passes through the wire pulling unit 3 and firstly surrounds the push wheel 44, and then passes through the guide wheel 11 to turn to the exit. Since the push wheel 44 is higher than the guide wheel 11, the operating wires 5 will not interfere with each other when winding. When the operating wire 5 is pulled, the guide wheel 11 and the main driving wheel 2 of the fixing member 31 are fixed. Therefore, when the two wires of the operating wire 5 are completely pulled out, the push wheel 44 will be pulled in the direction of the guide wheel 11. At the same time, the push cap 43 is pushed to move synchronously and linearly. When the push cap 43 is pushed, the internal mechanism of the casing assembly 41 is cyclically switched to allow the blocking bar 42 to extend or retract. And when the blocking rod 42 is extended, the cable frame 32 is locked (as shown in FIG. 2).

In this embodiment, the braking unit 4 is provided with two groups, and the positions corresponding to the braking positions of the two groups of the cable frame 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 both sides of the push wheel 44 to connect with the corresponding push cap 43. In addition, in order to ensure that the push wheel 44 can move smoothly and linearly when pulled by the operating wire 5, the carrier board 1 is provided with two sets of fixed carriages 46. A set of sliding frames 47 is additionally provided between the fixed sliding frames 46. Two sets of the push wheels 44 are installed in the sliding frame 47. The sliding frame 47 is restricted to only linearly slide between the two fixed sliding frames 46.

The braking unit 41 of the present invention adopts a cyclic switching mode. When the push cap 43 is pushed for the first time, the blocking rod 42 will be pushed out and locked by the linkage of the internal mechanism. After the push cap 43 is pushed again, the original blocking state is released and the blocking bar 42 is retracted. Such a cyclic switching operation achieves the required braking purpose without the assistance of electric power.

Next, a detailed description of this structure will be given. As shown in Figures 4 and 5, the housing assembly 41 further includes a front end fixing frame 411, a spring 412, a rear end fixing frame 413, a rotating pusher 414, and an outer tube 415 (partially in section in the figure) The way represents 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 to limit the moving direction and distance of the blocking bar 42. A boss 421 is provided on the periphery of the gear bar 42. The spring 412 is sleeved on the periphery of the front section of the gear bar 42 and is limited between the protrusion 421 and the front end fixing frame 411. The rear end fixing frame 413 is installed 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 axially installs the rotary pushing member 414 and the axial pushing member 416 in sequence, wherein the blocking rod 42 is inserted into the rotary pushing member 414. The pushing cap 43 is sleeved on the periphery of the axial pushing member 416 to move with it. When the push cap 43 is pushed, the axial pushing member 416 will move up and down. The axial pushing member 416 will cause the rotary pushing member 414 to rotate at an appropriate time, and then clamp the inner wall of the outer tube 415, so that the blocking rod 42 is pushed out. After the push cap 43 is pushed again, the blocking state is released 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 a plurality of sliding grooves 4151 and a plurality of first positioning inclined surfaces 4152 and a plurality of second positioning inclined surfaces 4153. The first locating inclined surface 4152 and the second locating inclined surface 4153 are alternately distributed on the inner wall in a ring shape. The lowest position of the first positioning inclined surface 4152 is connected with the sliding groove 4151. In addition, a slideway 4154 is provided between two adjacent slide grooves 4151. The radial depth of the slide 4154 is shallower than that of the slide 4151. The axial pushing member 416 has a number of helical teeth 4161 on its end surface, and a number of protrusions 4162 on its outer wall. After assembling, the protrusions 4162 will be located in the sliding groove 4151 and the sliding channel 4154 to maintain the axial pushing member 416 to be able to move axially in the outer sleeve 415. The outer wall of the rotary pushing member 414 has a plurality of convex bars 4141. The end of the convex strip 4141 has a slope 4142. The radial dimension of the protrusion 4141 is close to the sliding groove 4151.

As shown in FIGS. 6A to 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 drawings. As shown in FIG. 6A, in the unbraked state, the protruding bar 4141 of the rotary pushing member 414 is located in the sliding groove 4151. Part of the protrusion 4162 of the axial pushing member 416 is also located in the sliding groove 4151. However, the radial depth of the protrusion 4162 in the sliding groove 4151 is relatively shallow. The inclined tooth 4161 is in contact with the inclined surface 4142. As shown in FIG. 6B, when the axial pushing member 416 is pushed axially, the protruding strip 4141 is allowed to exit the sliding groove 4151, and then the inclined tooth 4161 is used to contact the inclined surface 4142 to guide the rotary 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 will then contact the second positioning inclined surface 4153. The rotary pushing member 416 continues to rotate. As shown in FIG. 6D, the inclined surface 4142 is finally clamped at the lowest position of the second positioning inclined surface 4153. Therefore, the rotary pushing member 414 is extended and locked, and the blocking rod 42 is extended relatively. If you want to release the card status afterwards, as shown in Figure 6E. When the axial pushing member 416 is pushed in again. The use of the inclined tooth 4161 is used to contact the inclined surface 4142 to guide the rotation of the rotary pushing member 416. Then the inclined surface 4142 will then contact the first positioning inclined surface 4152. Finally, the protruding bar 414 is slid into the sliding groove 4151 again, and the gear bar 42 will retract relatively. In this way, the purpose of cyclically switching braking can be achieved.

Next, an explanation will be given of the operation mode of the present invention. As shown in Figure 1, it is a three-dimensional view of the wire retracted state. The carrier board 1 can be installed at the ceiling of the room. The wire frame 32 is used to be far away from the fixing member 31, so that the line segment of the operating wire 5 is wound between the first guide wheels 311 and the second guide wheels 321 in sequence. In this way, the operating wire 5 is hidden in the wire pulling unit 3 on the carrier board 1 to prevent the operating wire 5 from being exposed and being pulled by children by mistake, thereby increasing safety and beauty.

When the operating wire 5 is pulled by a single wire to drive the main driving wheel 2 to rotate, as shown in FIG. 2. First, the operating wire 5 must be fully pulled out. When the wire is pulled out, the 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 wire is pulled, the wire pulling unit 3 with small acting resistance will act before the braking unit 4. Therefore, the two cable frames 32 will be pulled closer to the fixing member 31. The brake unit 4 does not act temporarily. When the two close together, the resistance of the cable unit 3 is greater than that of the brake unit 4 on the contrary. At this time, if the operating wire 5 is pulled continuously in two lines, the force will fall on the braking unit 4. Use card actions. This is the end state when the operation line 5 is pulled out. At this time, the operating wire 5 can be pulled by a single wire to drive the main driving wheel 2 to rotate.

Afterwards, if you want to take up the wire, pull the operating wire 5 with two wires again to release the blocking state of the brake unit 4. Perform the 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 assemblies, and achieves the purpose of achieving automatic wire take-up and single wire operation without using electric power. One way is explained, but it is not limited to only this way. The present invention will describe an embodiment of a lifting unit applied to a lamp. In general, if the lamp needs to be replaced, a ladder can be erected. This problem can be solved by the design of the present invention.

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

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

In the above embodiment, when the carrying platform 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 operating wire 5. After the operation line 5 is stored. The ceiling can only see the pull ring but not the line, which makes the appearance more beautiful. The user can borrow a tool to pull down the pull ring. Pull out the operating wire 5 hidden in the wire-drawing unit 3 on the carrier board 1, and then operate the lifting unit 6 to lift. Of course, the pipeline design of the interior decoration can also be used so that the end of the operating wire 5 after storage is located at the control panel of the wall, which is convenient for the user to pull out the operating wire 5 from the wall.

As shown in FIG. 10, an operation method used by the structure of the present invention is provided. The brake unit, the cable unit, the main drive wheel and the operating wire installed at the carrier board are used. The operating wire is a closed loop winding. The operating wire is stored on the carrier board by the wire pulling unit and only a part of it is exposed. The method of operation includes: Step A101: Pull down the two wires of the exposed section of the operating wire simultaneously, so that the storing section of the operating wire is pulled out; Step A102: When the operating wire cannot be pulled, the brake unit can be locked in the wire pulling unit; Step A103: Change the operating wire to be pulled by a single wire, and the member to be linked is driven by the operating wire; and Step A104: When the operating wire is pulled by the two wires at the same time again, the braking unit can release the blocking state applied to the wire pulling unit. The wire pulling unit resumes the wire take-up action again to pull the operating wire back and store it on the carrier board.

In step A103, when the operating wire is pulled by a single wire, the operating wire can be pulled clockwise or counterclockwise by a single wire in one direction. The operation wire drives the main driving wheel to rotate. As mentioned in the previous paragraph, the main driving 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 hiding. After being pulled out by two wires, it can be changed to a design that can be operated by a single wire. It is widely used in various lifting units and meets the requirements of patent application.
