A tensioning device for flexible scenery

Abstract

This application discloses a tensioning device for flexible scenery, comprising: a movable base; a mounting mechanism disposed on the movable base for mounting the main rattan of a rattan bridge; and a telescopic mechanism having a telescopic rod connected to the movable base for moving the movable base to tension the main rattan. When the tensioning device is in operation, the telescopic rod first controls the movable base to move closer to the rattan bridge. Then, the operator mounts the main rattan onto the mounting mechanism. Because the rattan bridge is not tensioned at this time, i.e., the main rattan is not tensioned, it is relatively easy to mount it onto the mounting mechanism. Then, the telescopic rod operates, causing the movable base to move away from the rattan bridge, at which point the main rattan can be quickly and reliably tensioned.

Description

Technical Field

[0001] This invention relates to the field of performing arts equipment, and more specifically to a tensioning device for flexible scenery. Background Technology

[0002] A rattan bridge is made by weaving multiple rattans into a net-like shape to form a bridge. It usually consists of multiple main rattans, and the rattan bridge can be built by pulling the main rattans taut.

[0003] In performance settings, it is sometimes necessary to build rattan bridges. Currently, the installation of the main rattan of the existing rattan bridge is entirely done by hand. The operator hangs one end of the main rattan of the rattan bridge on a fixed hanging point. This operation method requires a high level of skill, and the overall unfolded state of the rattan bridge is not good, which not only affects its use but also its aesthetics. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a tensioning device for flexible scenery.

[0005] The technical solution adopted in this invention is as follows:

[0006] A tensioning device for flexible scenery, comprising:

[0007] Portable seat;

[0008] The mounting mechanism, mounted on the movable base, is used to install the main rattan of the rattan bridge;

[0009] The telescopic mechanism has a telescopic rod connected to the movable seat, which is used to move the movable seat and tension the main rattan.

[0010] When the tensioning device is working, the telescopic rod first controls the moving seat to move to the side closer to the rattan bridge. Then the operator installs the main rattan on the hanging mechanism. Because the rattan bridge is not tensioned at this time, that is, the main rattan is not tensioned, it is relatively easy to install it on the hanging mechanism. Then the telescopic rod works to move the moving seat to the side away from the rattan bridge. At this time, the main rattan can be quickly and reliably tensioned.

[0011] In one embodiment of the present invention, the mounting mechanism includes a plurality of mounting components, the mounting components including:

[0012] The frame is fixed on the movable base;

[0013] Locking assembly, mounted on the rack;

[0014] A rotating component is rotatably mounted on the frame. The rotating component has a mounting part and a locking part. The mounting part is used to mount the main rattan of the rattan bridge. The rotating component has an initial working position and a locking working position. In the initial working position, the mounting part faces the rattan bridge. In the locking working position, the mounting part faces away from the rattan bridge, and the locking part cooperates with the locking assembly to lock the rotating component and keep it in the locking working position.

[0015] In the initial working position, the mounting part faces the rattan bridge side, which facilitates the installation or removal of the main rattan; in the locking working position, the mounting part faces away from the rattan bridge side, which effectively prevents the main rattan from detaching from the mounting part.

[0016] In practical applications, preferably, the end of the main rattan that mates with the hanging part has a hanging hole, through which the main rattan can be quickly hung on the hanging part.

[0017] In one embodiment of the present invention, the locking assembly includes:

[0018] A locking rod is slidably mounted on the frame. The locking rod has a first state and a second state. In the first state, the locking rod forms a limiting groove with the frame. When the rotating part is in the locking position, the end of the locking part is located in the limiting groove. In the second state, the locking rod moves and the locking part can disengage from the limiting groove.

[0019] An elastic element, which cooperates with the locking rod, is used to drive the locking rod to move, so that the locking rod has a tendency to maintain or switch to a first state.

[0020] The unlocking element is used to move the locking lever, causing the locking lever to switch from the first state to the second state.

[0021] In practical applications, the elastic element can be a tension spring or a compression spring.

[0022] In one embodiment of the present invention, the unlocking element is an automatic telescopic component.

[0023] In one embodiment of the present invention, each locking component shares a common unlocking element, the unlocking element comprising:

[0024] The first winding wheel is rotatably mounted on the movable seat;

[0025] Multiple first ropes, one end of each first rope is connected to a corresponding locking bar, and the other end is connected to the first winding reel;

[0026] The first take-up wheel drive mechanism is used to drive the first take-up wheel to rotate, thereby pulling multiple first ropes to move.

[0027] The unlocking element is designed in this way to unlock synchronously, and the whole structure is simple and reliable.

[0028] In one embodiment of the present invention, the first winding wheel drive mechanism is an electric push rod or a cylinder.

[0029] In one embodiment of the present invention, the locking assembly further includes rollers disposed on both sides of the locking rod.

[0030] The rollers reduce friction and ensure reliable movement of the locking bar.

[0031] In one embodiment of the present invention, the rotating member is V-shaped, and the end of the mounting part has an embedding groove. An anti-detachment member is hinged in the embedding groove. In the initial working position, the anti-detachment member is completely embedded in the embedding groove under its own weight. In the locked working position, the anti-detachment member is in a vertical state under its own weight, and the anti-detachment member and the mounting part form an anti-detachment angle.

[0032] Once the anti-detachment angle is formed, even if the main rattan is accidentally subjected to force and moves upward (moving upward along the length of the hanging part), it will not detach from the hanging part, thus increasing safety.

[0033] In one embodiment of the present invention, the mounting mechanism further includes a switching component, the switching component comprising:

[0034] Torsion springs, mounted on the rotating parts and the frame, are used to give the rotating parts a rotational tendency to turn toward the initial working position;

[0035] The second take-up reel is rotatably mounted on the movable seat;

[0036] Multiple second ropes, one end of which is connected to a corresponding rotating component, and the other end of which is connected to a second winding reel;

[0037] The second take-up wheel drive mechanism is used to drive the second take-up wheel to rotate, thereby pulling multiple second ropes to move, so that the rotating part overcomes the elastic force of the torsion spring and switches to the locking position.

[0038] In one embodiment of the present invention, the second winding wheel drive mechanism is a self-locking motor.

[0039] Compared to the locking lever's state switching, the rotating component's working position switching stroke is larger (the second rope moves a greater distance). If a cylinder or electric push rod is used, the required length is larger. Using a self-locking motor can effectively reduce the length. In addition, the second rope can be limited by self-locking, thus forming a double-lock structure to prevent the rotating component from unlocking due to the locking lever accidentally switching to the second state.

[0040] In one embodiment of the present invention, the tensioning device further includes a guide rail, and the movable seat cooperates with the guide rail via a movable wheel.

[0041] In one embodiment of the present invention, the telescopic mechanism is an electric push rod or a hydraulic cylinder.

[0042] The beneficial effects of the present invention are as follows: When the tensioning device is working, the telescopic rod first controls the moving seat to move to the side closer to the rattan bridge. Then the operator installs the main rattan on the hanging mechanism. Since the rattan bridge is not tensioned at this time, that is, the main rattan is not tensioned, it is easier to install it on the hanging mechanism. Then the telescopic rod works to move the moving seat to the side away from the rattan bridge. At this time, the main rattan can be tensioned quickly and reliably. Attached Figure Description

[0055] The present invention will now be described in detail with reference to the accompanying drawings.

[0056] Example 1

[0057] like Figures 1-5 As shown, this embodiment discloses a tensioning device 200 for a rattan bridge 100, the tensioning device 200 comprising:

[0058] Guide rail 4;

[0059] Movable seat 1, movable seat 1 is in movable cooperation with guide rail 4;

[0060] The mounting mechanism 2 is mounted on the movable seat 1 and is used to install the main rattan 101 of the rattan bridge 100;

[0061] The telescopic mechanism 3 has a telescopic rod 31, which is connected to the movable seat 1 and is used to drive the movable seat 1 to move, so that the main rattan 101 is tensioned.

[0062] When the tensioning device 200 is working, the telescopic rod 31 first controls the movable seat 1 to move to the side closer to the rattan bridge 100. Then, the operator installs the main rattan 101 onto the hanging mechanism 2. Because the rattan bridge 100 is not tensioned at this time, that is, the main rattan 101 is not tensioned, it is relatively easy to install it onto the hanging mechanism 2. Then, the telescopic rod 31 works, causing the movable seat 1 to move away from the rattan bridge 100 (see...). Figure 3 At this point, the main rattan 101 can be quickly and reliably tensioned.

[0063] like Figure 4 and 5 As shown, in this embodiment, the mounting mechanism 2 includes a plurality of mounting components 21, and the mounting components 21 include:

[0064] The frame 211 is fixed on the movable base 1;

[0065] Locking assembly 212 is mounted on frame 211;

[0066] The rotating component 213 is rotatably mounted on the frame 211. The rotating component 213 has a mounting part 2131 and a locking part 2132. The mounting part 2131 is used to mount the main rattan 101 of the rattan bridge 100. The rotating component 213 has an initial working position and a locking working position. In the initial working position, the mounting part 2131 faces the rattan bridge 100. In the locking working position, the mounting part 2131 faces away from the rattan bridge 100, and the locking part 2132 cooperates with the locking assembly 212, so that the rotating component 213 is locked and held in the locking working position.

[0067] In the initial working position, the mounting part 2131 faces the rattan bridge 100, which facilitates the installation or removal of the main rattan 101; in the locked working position, the mounting part 2131 faces away from the rattan bridge 100, which effectively prevents the main rattan 101 from detaching from the mounting part 2131.

[0068] In practical applications, preferably, the end of the main rattan 101 that mates with the hanging part 2131 has a hanging hole, through which the main rattan 101 can be quickly hung on the hanging part 2131.

[0069] like Figure 4 and 5 As shown, in this embodiment, the locking assembly 212 includes:

[0070] Locking rod 2121 is slidably mounted on frame 211. Locking rod 2121 has a first state and a second state. In the first state, locking rod 2121 and frame 211 form a limiting groove 2120. When rotating part 213 is in the locking position, the end of locking part 2132 is located in limiting groove 2120. In the second state, locking rod 2121 moves and locking part 2132 can disengage from limiting groove 2120.

[0071] The elastic element 214 cooperates with the locking rod 2121 to drive the locking rod 2121 to move, so that the locking rod 2121 has a tendency to maintain or switch to the first state.

[0072] The unlocking element is used to move the locking lever 2121, so that the locking lever 2121 switches from the first state to the second state.

[0073] In practical applications, the elastic element 214 can be a tension spring or a compression spring.

[0074] like Figure 4 and 5 As shown, the locking rod 2121 has a guide slope 2121a at one end near the rotating member 213. The guide slope 2121a is used to cooperate with the locking part 2132. When the locking part 2132 presses against the locking rod 2121, the locking part 2132 can drive the locking rod 2121 to move through the action of the guide slope 2121a, switching from the first state to the second state.

[0075] In practical applications, the unlocking element can be an automatic telescopic component.

[0076] like Figure 1 and 2 As shown, in this embodiment, each locking component 212 shares a common unlocking element, which includes:

[0077] The first winding wheel 2151 is rotatably mounted on the movable seat 1;

[0078] Multiple first ropes 2152, one end of the first rope 2152 is connected to the corresponding locking bar 2121, and the other end is connected to the first winding wheel 2151;

[0079] The first take-up wheel drive mechanism 2153 is used to drive the first take-up wheel 2151 to rotate, thereby pulling multiple first ropes 2152 to move.

[0080] The unlocking element is designed in this way to unlock synchronously, and the whole structure is simple and reliable.

[0081] In this embodiment, the first winding wheel drive mechanism 2153 is an electric push rod or a cylinder.

[0082] like Figure 4 and 5 As shown, in this embodiment, the locking assembly 212 further includes rollers 2122 disposed on both sides of the locking rod 2121. The rollers 2122 reduce friction and ensure reliable movement of the locking rod 2121.

[0083] like Figure 4 and 5 As shown, in this embodiment, the rotating member 213 is V-shaped.

[0084] In this embodiment, the movable seat 1 is connected to the guide rail 4 via movable wheels 11. The telescopic mechanism 3 is an electric push rod or a hydraulic cylinder.

[0085] Example 2

[0086] like Figure 6 As shown, one difference between this embodiment and embodiment 1 is that the end of the mounting part 2131 has an embedding groove, and an anti-detachment member 2133 is hinged in the embedding groove. In the initial working position, the anti-detachment member 2133 is completely embedded in the embedding groove under its own weight. In the locked working position, the anti-detachment member 2133 is in a vertical state under its own weight, and the anti-detachment member 2133 and the mounting part 2131 form an anti-detachment angle 2134.

[0087] After the anti-detachment angle 2134 is formed, even if the main rattan 101 is accidentally subjected to force and moves upward (moving upward along the length direction of the hanging part 2131), it will not detach from the hanging part 2131, thus ensuring higher safety.

[0088] like Figure 7 As shown, another difference between this embodiment and embodiment 1 is that the mounting mechanism 2 further includes a switching component, which includes:

[0089] A torsion spring (not shown in the figure) is provided on the rotating part 213 and the frame 211 to give the rotating part 213 a rotational tendency to turn to the initial working position;

[0090] The second take-up wheel 221 is rotatably mounted on the movable seat 1;

[0091] Multiple second ropes 222, one end of each second rope 222 is connected to a corresponding rotating component 213, and the other end is connected to a second winding reel 221;

[0092] The second winding wheel 221 drive mechanism (not shown in the figure) is used to drive the second winding wheel 221 to rotate, thereby pulling multiple second ropes 222 to move, so that the rotating part 213 overcomes the elastic force of the torsion spring and switches to the locking position.

[0093] By switching the torsion spring of the component and the drive mechanism of the second winding wheel 221, the working position of the rotating part 213 can be automatically switched, making the whole operation more convenient.

[0094] In practical applications, the drive mechanism for the second winding reel 221 is preferably a self-locking motor. Compared to the state switching of the locking lever 2121, the working position switching stroke of the rotating component 213 is larger (the second rope 222 moves a greater distance). If a cylinder or electric push rod is used, the required length would be larger. Using a self-locking motor can effectively reduce the length. In addition, the second rope 222 can be limited by self-locking, thus forming a double-lock structure to prevent the rotating component 213 from unlocking due to the locking lever 2121 accidentally switching to the second state.

[0095] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
