Description

Technical Field

[0001] This application relates to the technical field of agricultural machinery, and in particular to a take-up device. Background Technology

[0002] Agricultural tillers are widely used machines in agricultural production, primarily for tilling, sowing, and harvesting. Their core functions rely on the coordinated operation of various mechanical components, such as braking systems and gear shifting mechanisms. These components are controlled via wiring harnesses (such as brake cables and shift cables). The proper layout and protection of these wiring harnesses are crucial to the stability and lifespan of the agricultural tiller.

[0003] Currently, wiring harness management in agricultural machinery mostly employs simple binding or fastening clips to directly fix the wiring harness to the handle or machine body surface. Some solutions use plastic cable ties or metal clips for fixing, which can temporarily organize the wiring harness, but lacks targeted design.

[0004] In existing technologies, the wiring harnesses are disorganized and exposed to the external environment, making them susceptible to damage from friction, collisions, or environmental corrosion, which can lead to operational malfunctions or safety hazards. Furthermore, the mounting and disassembly of the fixing devices are inconvenient, resulting in low maintenance efficiency. Utility Model Content

[0005] In order to achieve close-fitting storage and quick assembly / disassembly of wire harnesses, and significantly reduce the probability of wire harness damage, this application provides a wire take-up device.

[0006] This application provides a cable take-up device, which adopts the following technical solution:

[0007] A cable retractor includes a housing disposed on a handle or body surface, and a clamping assembly for securing and fixing a cable harness is provided on the housing. The clamping assembly includes:

[0008] Sliding blocks, two sets of which are symmetrically slidably disposed on the housing;

[0009] A compression spring is disposed inside the housing, and two sets of the compression springs are respectively used to push two sets of sliding blocks to slide in a direction that brings them closer to each other;

[0010] A locking element is disposed on the sliding block and is used to lock and fix the wire harness between the two sets of sliding blocks.

[0011] By adopting the above technical solution, the housing is fixedly installed on the handle or body, and then the two sets of sliding blocks are pushed away from each other. The wire harness is then placed between the two sets of sliding blocks, and the two sets of sliding blocks are clamped by the compression spring. Then, the top of the wire harness is locked and fixed by the locking device, thereby reducing the probability of the wire harness coming off the housing, realizing the close storage and quick disassembly of the wire harness, and significantly reducing the probability of wire harness damage.

[0012] Furthermore, the locking member is a fixing strap that is hinged at one end to one of the sliding blocks. The other side of the fixing strap is provided with a hook and loop fastener. The other set of sliding blocks is provided with a hook and loop fastener that cooperates with the hook and loop fastener on the fixing strap. The fixing strap is used to prevent the wire harness between the two sets of sliding blocks from detaching from the sliding blocks.

[0013] By adopting the above technical solution, the Velcro fastening strap provides convenient operation for quick tightening and loosening. At the same time, the cooperation between the Velcro loop side and the Velcro hook side ensures a secure fixation to the top of the wire harness, reducing the probability of the wire harness coming off the sliding block.

[0014] Furthermore, a limiting seat is provided on the housing. The limiting seat is inserted into the housing and located between two sets of sliding blocks. The limiting seat is used to limit the minimum distance between two adjacent sets of sliding blocks.

[0015] By adopting the above technical solution, the limiting seat prevents the wire harness from being over-compressed and causing damage to the outer sheath by limiting the minimum spacing of the sliding blocks, while ensuring clamping stability, and is suitable for fixing wire harnesses of different thicknesses.

[0016] Furthermore, an arc-shaped groove is provided on the side of the sliding block near the wire harness, and an elastic pad is provided on the arc-shaped groove.

[0017] By adopting the above technical solution, the design of the arc groove and elastic gasket increases the contact area of ​​the wire harness, disperses local pressure, and reduces friction and wear. At the same time, the elastic gasket provides buffer protection and reduces the probability of damage to the wire harness.

[0018] Furthermore, the housing is detachably mounted on the handle or body surface via a snap-fit ​​mechanism, the snap-fit ​​mechanism comprising:

[0019] T-blocks are provided on the surface of the handle or body;

[0020] A connecting block is provided on the bottom of the housing, and the connecting block has a snap-fit ​​groove that slides and engages with the T-shaped block;

[0021] A locking assembly is disposed on the connecting block and is used to lock the connecting block onto the T-block.

[0022] By adopting the above technical solution, the sliding snap-fit ​​design of the T-block and the snap-fit ​​groove enables the quick installation and disassembly of the housing, and the locking component ensures that the housing is firmly fixed under complex working conditions, thereby improving maintenance efficiency and reliability.

[0023] Furthermore, a locking groove is formed on the upper surface of the T-block, and the locking assembly includes:

[0024] A locking rod is slidably mounted on the connecting block. After the locking rod is inserted into the locking groove, it locks the connecting block onto the T-shaped block.

[0025] A locking spring is provided on the connecting block and is used to push the locking rod to slide towards the locking groove;

[0026] A pull cord is slidably mounted on the housing and connected to the locking rod. The pull cord facilitates pulling the locking rod to slide away from the locking groove.

[0027] By adopting the above technical solution, the locking spring pushes the locking rod to automatically embed into the locking groove, realizing one-click locking. The unlocking operation is simplified by pulling the rope. Users only need to pull the rope to separate the shell, which takes into account both safety and convenience.

[0028] Furthermore, a pull ring is provided on the side of the pull rope away from the locking bar, and the pull ring is made of flexible rope.

[0029] By adopting the above technical solution, the flexible rope pull ring reduces the required operating force and makes it easy to store the pull ring when not in use.

[0030] Furthermore, the housing is provided with a protective cover for protecting the pull ring, and the housing is provided with a storage tube for storing the pull cord and pull ring. The protective cover is threaded inside the storage tube and is used to protect the pull ring and pull cord.

[0031] By adopting the above technical solution, the storage tube stores the pull rope and pull ring, and the threaded protective cover effectively prevents rainwater and dust from entering the pull ring, extending the service life of the device, while maintaining a clean appearance and adapting to complex outdoor environments.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] The connecting block and the T-block slide and engage, and then the locking pin is inserted into the locking groove to prevent the connecting block and the T-block from sliding relative to each other, thereby locking the housing onto the handle or body. Then, the two sets of sliding blocks are pushed away from each other, and the wire harness is placed between the two sets of sliding blocks. The compression spring pushes the two sets of sliding blocks to clamp the wire harness, and then the top of the wire harness is locked and fixed by the fixing strap, thereby reducing the probability of the wire harness coming off the housing, realizing the close storage and quick assembly and disassembly of the wire harness, and significantly reducing the probability of wire harness damage.

Detailed Implementation

[0038] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0039] This application discloses a take-up device.

[0040] Reference Figure 1 A cable retractor includes a housing 1, which is disposed on the surface of a handle or body, and a clamping assembly 5 for clamping and fixing the cable harness is provided on the housing 1.

[0041] Reference Figure 1 and Figure 2 The housing 1 is detachably mounted on the handle or body surface via a snap-fit ​​mechanism 2. The snap-fit ​​mechanism 2 includes a T-shaped block 21 and a connecting block 22. The bottom of the T-shaped block 21 is fixedly mounted on the handle or body surface. The connecting block 22 is fixedly mounted on the bottom of the housing 1. The connecting block 22 has a snap-fit ​​groove 221 that slides and snaps into the T-shaped block 21. During installation, the connecting block 22 is moved to allow the T-shaped block 21 and the connecting block 22 to slide and connect. Through the snap-fit ​​between the T-shaped block 21 and the snap-fit ​​groove 221, the connecting block 22 can only slide along the length of the T-shaped block 21. In this embodiment, the T-shaped block 21 can be fixed to the handle or body by any of the following methods: bolt connection, adhesive fixation, magnetic adsorption fixation, welding fixation, etc.

[0042] Reference Figure 2The locking mechanism 2 also includes a locking assembly 3, which is mounted on the connecting block 22. The locking assembly 3 is used to lock the connecting block 22 onto the T-block 21 to prevent the connecting block 22 from sliding along the length of the T-block 21. The locking assembly 3 includes a locking rod 31, a locking spring 32, and a pull rope 33. A locking groove 211 is provided on the upper surface of the T-block 21. The locking rod 31 is slidably mounted on the connecting block 22. The axis of the locking rod 31 is parallel to the axis of the locking groove 211. When the connecting block 22 moves to a designated position, the axis of the locking rod 31 coincides with the axis of the locking groove 211. When the locking rod 31 is inserted into the locking groove 211, the locking rod 31 locks the connecting block 22 onto the T-block 21. The locking spring 32 is fixedly mounted on the connecting block 22 and is used to push the locking rod 31 closer to the locking rod. The locking rod 31 slides in the direction of the locking groove 211. After the locking rod 31 is inserted into the locking groove 211, the locking spring 32 pushes the locking rod 31 to slide closer to the locking groove 211, thereby preventing the locking rod 31 from sliding out of the locking groove 211. Finally, it works together with the T-block 21 to lock the connecting block 22 onto the handle or body surface. The pull rope 33 is slidably installed on the housing 1 and connected to the locking rod 31. The pull rope 33 facilitates pulling the locking rod 31 to slide away from the locking groove 211. When it is necessary to release the locking rod 31 from the connecting block 22, the locking rod 31 is pulled out of the locking groove 211 by the pull rope 33, thereby releasing the locking rod 31 from the connecting block 22. In this embodiment, a set of locking components 3 are provided on both ends of the connecting block 22. The two sets of locking components 3 together lock the connecting block 22 onto the T-block 21.

[0043] Reference Figure 2 To facilitate pulling the pull rope 33, a pull ring 34 is fixedly installed on the pull rope 33. The pull ring 34 is made of flexible rope. When it is necessary to release the lock on the connecting block 22, the pull ring 34 facilitates the sliding of the pull rope 33. After the connecting block 22 is locked, the pull ring 34 is placed on the housing 1. The flexible rope characteristic reduces the space occupied by the pull ring 34.

[0044] Reference Figure 2 A storage tube 4 for storing the pull rope 33 and pull ring 34 is fixedly installed on the housing 1. A protective cover for protecting the pull ring 34 is provided on the housing 1. The protective cover is threaded on the storage tube 4. Since the pull ring 34 is made of flexible rope, when the pull ring 34 is not in use, the pull ring 34 and pull rope 33 are stored in the storage tube 4. By threading the protective cover on the storage tube 4, the pull ring 34 is covered, reducing the probability of the locking rod 31 slipping out of the locking groove 211 due to accidental pulling of the pull ring 34.

[0045] Reference Figure 1 and Figure 2The clamping assembly 5 includes sliding blocks 51 and compression springs 52. Two sets of sliding blocks 51 are provided, and the two sets of sliding blocks 51 are symmetrically slidably disposed on the housing 1. An arc-shaped groove is opened on the opposite side of the two sets of sliding blocks 51, and an elastic pad 511 is fixedly installed on the arc-shaped groove to improve the clamping and fixing effect of the two sets of sliding blocks 51 on the wire harness. The compression springs 52 are disposed inside the housing 1, and two sets of compression springs 52 are provided. The two sets of compression springs 52 are used to push the two sets of sliding blocks 51 respectively. The two sets of compression springs 52 are used to push the sliding blocks 51 to slide in a direction that brings them closer to each other, thereby clamping and fixing the wire harness between the two sets of sliding blocks 51.

[0046] Reference Figure 1 The clamping assembly 5 also includes a locking member, which is disposed on the sliding block 51 and used to lock and fix the wire harness between the two sets of sliding blocks 51. The locking member is a fixing strap 6 with one end hinged and fixedly installed on one set of sliding blocks 51. A patterned hook surface is fixedly installed on the other end of the fixing strap 6. A hook and loop fastener that cooperates with the hook and loop fastener on the fixing strap 6 is fixedly installed on the upper surface of the other set of sliding blocks 51. When the hook and loop fastener on the fixing strap 6 cooperates with the hook and loop fastener on the sliding block 51, the fixing strap 6 is used to prevent the wire harness between the two sets of sliding blocks 51 from detaching from the sliding block 51, thereby improving the fixing effect of the wire harness.

[0047] Reference Figure 2 and Figure 3 A limiting seat 7 is provided on the housing 1. The limiting seat 7 is inserted and installed on the housing 1. The limiting seat 7 is located between two sets of sliding blocks 51. The limiting seat 7 is used to limit the minimum distance between two adjacent sets of sliding blocks 51, thereby reducing the probability of the two sets of sliding blocks 51 excessively squeezing the wire harness. The limiting seat 7 has an arc-shaped support groove for supporting the bottom of the wire harness. The limiting seat 7 is provided with multiple sizes according to the size of the limiting distance value. The arc of the arc-shaped support groove corresponding to the multiple sets of limiting seats 7 is different, so as to better support the bottom of the wire harness.

[0048] The working principle of this application embodiment is as follows:

[0049] The connecting block 22 and the T-block 21 slide and engage, and then the locking pin is inserted into the locking groove 211 to prevent the connecting block 22 and the T-block 21 from sliding relative to each other, thereby locking the housing 1 onto the handle or body. Then, the two sets of sliding blocks 51 are pushed away from each other, and the wire harness is placed between the two sets of sliding blocks 51. The compression spring 52 pushes the two sets of sliding blocks 51 to clamp the wire harness, and then the fixing strap 6 locks and fixes the top of the wire harness, thereby reducing the probability of the wire harness coming off the housing 1, realizing the close storage and quick disassembly and assembly of the wire harness, and significantly reducing the probability of wire harness damage.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
