[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0026] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise stated in this invention, both endpoints of each numerical range and any value between the two endpoints may be selected. Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of this invention, may be implemented using any prior art methods, devices, and materials similar to or equivalent to those described, used, or made of materials in the embodiments of this invention.

[0027] To achieve the above objectives, this utility model provides a tension wheel folding handle structure, characterized in that it includes a transmission assembly 1 and a handle assembly 2, wherein the handle assembly 2 and the transmission assembly 1 are hinged together, and the handle assembly 2 has a first position and a second position.

[0028] The handle assembly 2 is in the first position, and the handle assembly 2 and the transmission assembly 1 are on the same straight line; the handle assembly 2 is in the second position, and the handle assembly 2 and the transmission assembly 1 are arranged crosswise on the plane. Rotating the handle assembly 2 causes the transmission assembly 1 to rotate around its central axis.

[0029] In this embodiment, the handle assembly 2 has a first position and a second position. When the handle assembly 2 is in the first position, the handle assembly 2 and the transmission assembly 1 are on the same straight line, which makes it easy for the packing strap to be put into the tensioning wheel. When the handle assembly 2 is in the second position, the handle assembly 2 and the transmission assembly 1 are arranged crosswise on the plane. At this time, the handle assembly 2 and the transmission assembly 1 are locked to each other. When the operator rotates the handle assembly 2, the tensioning wheel can be driven to rotate forward or backward along the central axis of the transmission assembly 1, which is convenient and quick and can improve production efficiency.

[0030] It should be noted that the transmission assembly 1 is hinged to the handle assembly 2, and the handle assembly 2 can only rotate in a single plane, that is, the handle assembly 2 can rotate in the plane corresponding to the first position and the second position, but cannot rotate in other planes.

[0031] In one embodiment, the transmission assembly 1 includes a threaded sleeve 11, a slider 12 installed inside the threaded sleeve 11, a bevel gear spindle 13, and a helical gear 14 installed at the end of the bevel gear spindle 13. The helical gear 14 is sleeved on one end of the bevel gear spindle 13, and the other end of the bevel gear spindle 13 is provided with an external thread. The inner wall of the threaded sleeve 11 is provided with an internal thread, and the bevel gear spindle 13 and the threaded sleeve 11 are detachably connected.

[0032] In this embodiment, the threaded sleeve 11 and the bevel gear spindle 13 are connected by threads. The threaded sleeve 11 and the bevel gear spindle 13 are detachable, which facilitates disassembly, assembly and maintenance. The helical gear 14 is installed at the end of the bevel gear spindle 13. When the operator rotates the handle assembly 2 to drive the transmission assembly 1 to rotate, the helical gear 14 can drive the gear meshing with it to rotate, thereby controlling the tension of the tension wheel.

[0033] In one embodiment, a groove is provided at the bottom of the end where the bevel gear spindle 13 is connected to the threaded end sleeve 11, and the slider 12 is partially embedded in the groove and slidably disposed inside the threaded end sleeve 11.

[0034] In this embodiment, the bottom of the bevel gear spindle 13 is provided with a groove, and the slider 12 is partially embedded in the groove and slidably disposed inside the threaded sleeve 11. When the operator rotates the handle assembly 2, the slider 12 connected to the handle assembly 2 can lock the bevel gear spindle 13 and the threaded sleeve 11, reducing the mutual rotation between the bevel gear spindle 13 and the threaded sleeve 11, so that the transmission assembly 1 can perform transmission more stably.

[0035] It should be noted that the end of the slider 12 has a protrusion 122 that matches the groove, and when the handle assembly 2 is in the second position, the protrusion 122 is embedded in the groove.

[0036] In one embodiment, the handle assembly 2 includes a clip 21, a crank 22, a first pin 23 and a second pin 24. The first pin 23 passes through one end of the clip 21 and is connected to the end of the threaded sleeve 11. The second pin 24 is disposed at the other end of the clip 21 and passes through the crank 22 and the clip 21.

[0037] In this embodiment, the first pin 23 is connected to the end of the threaded sleeve 11, and the second pin 24 is disposed on the other end of the clamp 21 opposite to the first pin 23. The crank handle 22 is connected to the second pin 24. This structure is relatively stable, can provide relatively smooth transmission, has a relatively simple connection relationship, and has low maintenance costs.

[0038] It should be noted that the first pin 23 is set on the threaded sleeve 11 and passes through one end of the clamping piece 21, and the second pin 24 is set on the other end of the clamping piece 21. The clamping piece 21 rotates around the first pin 23, and the crank 22 rotates around the second pin 24.

[0039] In one embodiment, a pin 121 is provided at the bottom of the slider 12, and a cam groove 211 corresponding to the pin 121 is provided on the clip 21, with the pin 121 passing through the cam groove 211.

[0040] In this embodiment, a pin 121 is provided at the bottom of the slider 12. The pin 121 passes through the cam groove 211 on the clamp 21. When the clamp 21 rotates around the first pin 23, the pin 121 moves synchronously in the cam groove 211. In this way, the slider 12 can be moved inside the threaded sleeve 11 by rotating the clamp 21.

[0041] In one embodiment, a cam groove 211 is formed at the end of the clamping piece 21 and is arranged around the first pin 23. The distance between the cam groove 211 and the first pin 23 gradually decreases along the direction from the edge of the clamping piece 21 to the first pin 23.

[0042] In this embodiment, along the direction from the edge of the clip 21 to the first pin 23, the distance between the cam groove 211 and the first pin 23 gradually decreases. When the clip 21 is rotated, since the pin 121 passes through the cam groove 211, the pin 121 drives the slider 12 to move accordingly, thereby adjusting the position of the slider 12 in the thread sleeve 11.

[0043] For example, when the clip 21 is arranged crosswise with the transmission assembly 1, the slider 12 is embedded in the groove of the bevel gear spindle 13, which can lock the threaded pair. At this time, the handle assembly 2 will not fall off no matter whether it rotates forward or backward.

[0044] In one embodiment, the crank handle 22 includes a crank handle body 221, a spring, and a buckle 222. A receiving groove is provided on one end of the crank handle body 221 opposite to the second pin 24. The spring and the buckle 222 are disposed in the receiving groove. One end of the spring abuts against the inner wall of the receiving groove, and the other end is connected to the buckle 222.

[0045] In this embodiment, a spring and a buckle 222 are provided on the crank body 221, which facilitates the storage and locking of the crank 22 and improves the convenience of using the crank 22.

[0046] In one embodiment, the end of the latch 222 has a clearance groove adapted to the first pin 23.

[0047] In this embodiment, the end of the buckle 222 is provided with an avoidance groove that is adapted to the first pin 23, which can make the crank handle 22 more stably abut against the first pin 23, and facilitate the storage of the crank handle 22.

[0048] In one embodiment, there are multiple clips 21, which are arranged opposite to each other on the first pin 23, and the handle 22 is installed between the multiple clips 21.

[0049] In this embodiment, the clips 21 are disposed opposite to the first pin 23, and the crank 22 is installed between the multiple clips 21. This allows the crank 22 and the clips 21 to be connected relatively stably through the second pin 24, maintaining the reliability and stability of the handle assembly 2 during rotation.

[0050] For example, there are two clips 21, which are arranged opposite each other on both sides of the first pin 23, and the handle 22 is installed between the two clips 21.

[0051] In one embodiment, the slider 12 has a square structure that adapts to the internal space of the threaded sleeve 11.

[0052] In this embodiment, the slider 12 has a square structure. When the slider 12 is embedded in the groove inside the bevel gear spindle 13, it can reduce the relative rotation between the bevel gear spindle 13 and the threaded sleeve 11, thereby improving the stability of the transmission.

[0053] The above technical solutions of this utility model are merely preferred embodiments and do not limit the patent scope of this utility model. All equivalent structural transformations made under the technical concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of this utility model.
