Description

Technical Field

[0001] This utility model belongs to the technical field of binding and reinforcement devices, and specifically relates to a steel cable fixing buckle. Background Technology

[0002] The rapid development of modern society is inseparable from the continuous progress of the logistics industry. From the transportation of small commodities for daily life to the transportation of large items such as automobiles and industrial equipment, all rely on the support of modern logistics. Transporting large equipment such as automobiles requires the use of special transport vehicles or even trains. Before transportation, the equipment to be transported needs to be secured to the flatbed of the transport vehicle. For stable securing, steel cables are often used in logistics for binding, and ratchet-type wire rope buckles are used at the ends of the steel cables for connection and fixation.

[0003] Traditional ratchet-type wire rope locks secure and tighten the wire rope using a ratchet, but they are difficult to untie if there are issues such as incorrect binding requiring adjustment. In such cases, the operator needs to use their hand or a screwdriver to pry open the return spring on the ratchet latch, allowing the ratchet to release its locking mechanism before the rope can be untied.

[0004] Such operations are cumbersome, and the return spring is not easy to pry open. During the process of prying open, the hand can easily be injured when it is inserted into the device. Moreover, it is also troublesome to untie the return spring and then put it back into use. These problems have brought inconvenience to untying the steel cable. Some operators even cut the steel cable directly to make it easier to untie it, resulting in unnecessary waste. Utility Model Content

[0005] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a steel cable fixing buckle that can be easily unfastened.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A steel cable fastening buckle includes a buckle body with a cable winding groove, a winding shaft rotatably connected to the buckle body, a ratchet fixed to one end of the winding shaft, a through cable hole between the winding shaft and the ratchet, one end of a steel cable being sleeved on the cable winding groove, and the other end of the steel cable being wound around the winding shaft and passing through the cable hole; a pawl rotatably connected to the buckle body, the pawl engaging with the ratchet, a return spring connecting the pawl and the buckle body, a movable locking plate fixed to the pawl, and a pushing mechanism for pushing the movable locking plate connected to the buckle body.

[0008] When using steel cables to secure goods, first pass one end of the cable through the cable winding groove and then secure that end. After the cable is wrapped and the goods are securely fastened, insert it into the buckle body, through the cable insertion hole, and out through the center of the ratchet. At this point, the cable is locked in the cable insertion hole. Rotating the winding shaft gradually winds the cable around it, tightening the lock on the goods. The ratchet rotates in the direction of locking the cable, ensuring the cable securely binds the goods. Because the ratchet teeth are tilted in the opposite direction of ratchet rotation, the ratchet will not flip due to the engaging action of the pawl. For added safety, a return spring connects the pawl and the buckle body to prevent the pawl from disengaging from the ratchet, ensuring the cable securely binds the goods.

[0009] To untie, simply operate the push mechanism. This mechanism moves the movable plate, causing it to rotate the pawl, disengaging it from the ratchet. The ratchet can then rotate freely to untie the cable. If the cable was incorrectly tied and needs retying, after untying, readjust the binding and allow the pawl to spring back and engage the ratchet. This will allow you to rotate the winding shaft again to tighten the cable.

[0010] This invention features a movable locking plate and a pushing mechanism. By operating the pushing mechanism, the movable locking plate is pushed, causing the pawl to rotate and disengage from the ratchet, thus untying the steel cable. After the pawl disengages from the ratchet, the pushing mechanism stabilizes the movable locking plate in that position. Therefore, the operator does not need to constantly pry open the pawl; simply rotating the winding shaft is sufficient to unlock the steel cable. This convenient operation avoids the risk of injury that can occur when prying open the pawl.

[0011] As a preferred embodiment of this utility model, the pushing mechanism includes a pushing rod and a fixed plate fixed to the buckle body. The pushing rod includes a smooth rod section and a threaded section. The threaded section is threadedly connected to the fixed plate. The movable plate is provided with a locking groove. The smooth rod section is sleeved in the locking groove. The inner diameter of the locking groove is smaller than the diameter of the threaded section.

[0012] When untying is required, rotate the push rod, and the threaded section of the push rod moves helically relative to the fixed clamping plate. Since the inner diameter of the locking groove is smaller than the diameter of the threaded section, the stepped surface between the threaded section and the smooth rod section can push the movable clamping plate to move, causing the pawl to rotate. There is a certain gap between the locking groove of the movable clamping plate and the smooth rod section, so that when the stepped surface pushes the movable clamping plate to rotate within a small angle, no motion interference will occur.

[0013] As a preferred embodiment of this utility model, the locking groove of the movable locking plate has an opening on one side, and the opening direction of the locking groove is perpendicular to the rotation axis of the pawl. When the movable locking plate is pushed to rotate, the movable locking plate rotates around the rotation axis of the pawl. Since the opening direction of the locking groove is perpendicular to the rotation axis of the pawl, the opening of the locking groove can avoid the push rod rotating relative to the movable locking plate, ensuring that the helical motion of the push rod can be converted into the rotation of the pawl.

[0014] In a preferred embodiment of this invention, a gasket is provided between the movable plate and the fixed plate. The gasket is fitted onto the smooth rod section, and its inner diameter is smaller than that of the locking groove. The inner diameter of the locking groove is larger than that of the gasket, thus further increasing the gap between the locking groove and the smooth rod section. This further prevents movement interference between the pushing rod and the movable plate when the stepped surface pushes the movable plate. The gasket is relatively thin, allowing it to tilt at a large angle relative to the pushing rod, thus preventing movement interference between the gasket and the pushing rod.

[0015] In a preferred embodiment of this invention, the push rod further includes a limiting section located at the end of the smooth rod section away from the threaded section. A limiting nut is threaded onto the limiting section, and the limiting nut is located on the side of the movable clamping plate away from the fixed clamping plate. The limiting nut on the limiting section can limit the movable clamping plate, preventing it from dislodging from the push rod.

[0016] In a preferred embodiment of this invention, the push rod further includes a connector located at the end of the threaded section away from the smooth rod section, and a handle is connected to the connector. After the handle is connected to the connector, the push rod can be rotated by operating the handle, facilitating operation.

[0017] As a preferred embodiment of this utility model, the connector head has several engaging grooves, and the handle is connected to several engaging pins, with the engaging pins and engaging grooves corresponding to each other.

[0018] As a preferred embodiment of this utility model, a pad is provided inside the cable winding groove. The pad thickens the cable winding groove, increases the strength of the cable winding groove, and prevents the cable from damaging the cable winding groove when the cable is tightened.

[0019] As a preferred embodiment of this utility model, the cross-sectional shape of the cable groove is arc-shaped to avoid stress concentration.

[0020] In a preferred embodiment of this invention, the end of the winding shaft furthest from the ratchet is provided with an operating head for engaging with a wrench. The operating head has a square cross-section for easy engagement with the wrench.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention features a movable locking plate and a pushing mechanism. By operating the pushing mechanism, the movable locking plate is pushed, causing the pawl to rotate and disengage from the ratchet, thus untying the steel cable. After the pawl disengages from the ratchet, the pushing mechanism stabilizes the movable locking plate in that position. Therefore, the operator does not need to constantly pry open the pawl; simply rotating the winding shaft is sufficient to unlock the steel cable. This convenient operation avoids the risk of injury that can occur when prying open the pawl. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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 some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0036] like Figures 1-4 As shown, the steel cable fastening buckle of this embodiment includes a buckle body 1, a cable winding groove 11 on the buckle body 1, a winding shaft 2 rotatably connected to the buckle body 1, a ratchet 3 fixed to one end of the winding shaft 2, and a through cable hole 21 between the winding shaft 2 and the ratchet 3. One end of the steel cable 4 is sleeved on the cable winding groove 11, and the other end of the steel cable 4 is wound around the winding shaft 2 and passes through the cable hole 21. A pawl 5 is rotatably connected to the buckle body 1, the pawl 5 engages with the ratchet 3, a return spring 51 is connected between the pawl 5 and the buckle body 1, a movable locking plate 6 is fixed to the pawl 5, and a pushing mechanism 7 for pushing the movable locking plate 6 is connected to the buckle body 1. An operating head 22 for cooperating with a wrench is provided at the end of the winding shaft 2 away from the ratchet 3. The operating head 22 has a square cross-section for easy cooperation with a wrench.

[0037] When using the steel cable 4 to bind goods, first pass one end of the steel cable 4 through the cable groove 11 and then fix that end. After the steel cable 4 is wrapped around and the goods are securely bound, insert it into the buckle body 1, pass through the cable hole 21, and then exit from the center of the ratchet 3. At this time, the steel cable 4 is locked in the cable hole 21. Turn the operating head 22 with a wrench, the winding shaft 2 rotates, and the steel cable 4 gradually winds around the winding shaft 2, tightening the lock on the goods. The ratchet 3 rotates in the direction of locking the steel cable 4, so that the steel cable 4 securely binds the goods. Since the teeth of the ratchet 3 are tilted in the opposite direction of the ratchet 3's rotation, the ratchet 3 will not flip under the locking action of the pawl 5. For safety, a return spring 51 is connected between the pawl 5 and the buckle body 1 to prevent the pawl 5 from disengaging from the ratchet 3, ensuring that the steel cable 4 binds the goods.

[0038] To untie, simply operate the push mechanism 7. The push mechanism 7 moves the movable locking plate 6, which in turn rotates the pawl 5, disengaging it from the ratchet 3. At this point, the ratchet 3 can rotate freely, and rotating it will untie the steel cable 4. If the cable was incorrectly tied and needs to be re-tied, after unlocking, readjust the binding and then allow the pawl 5 to spring back and engage the ratchet 3. This will allow the winding shaft 2 to be rotated again to tighten the steel cable 4.

[0039] This utility model is equipped with a movable locking plate 6 and a pushing mechanism 7. By operating the pushing mechanism 7, the movable locking plate 6 is pushed, causing the movable locking plate 6 to rotate the pawl 5, thereby disengaging the pawl 5 from the ratchet 3 and untying the steel cable 4. After the pawl 5 is disengaged from the ratchet 3, the pushing mechanism 7 stabilizes the movable locking plate 6 in that position. Therefore, the operator does not need to pry open the pawl 5 continuously; they only need to rotate the winding shaft 2 to unlock the steel cable 4. This is convenient to operate and avoids the problem of easy injury when prying open the pawl 5.

[0040] Specifically, such as Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, the pushing mechanism 7 includes a pushing rod 71 and a fixed clamping plate 72 fixed on the buckle body 1. The pushing rod 71 includes a smooth rod section 711 and a threaded section 712. The threaded section 712 is threadedly connected to the fixed clamping plate 72. The movable clamping plate 6 is provided with a clamping groove 61. The smooth rod section 711 is sleeved in the clamping groove 61. The inner diameter of the clamping groove 61 is smaller than the diameter of the threaded section 712.

[0041] When untying is required, the push rod 71 is rotated, and the threaded section 712 of the push rod 71 moves helically relative to the fixed clamping plate 72. Since the inner diameter of the locking groove 61 is smaller than the diameter of the threaded section 712, the stepped surface between the threaded section 712 and the smooth rod section 711 can push the movable clamping plate 6 to move, and the movable clamping plate 6 drives the pawl 5 to rotate. There is a certain gap between the locking groove 61 of the movable clamping plate 6 and the smooth rod section 711, so that when the stepped surface pushes the movable clamping plate 6 to rotate within a small angle, no motion interference will occur.

[0042] To avoid motion interference, the locking groove 61 of the movable locking plate 6 has an opening on one side, and the opening direction of the locking groove 61 is perpendicular to the rotation axis of the pawl 5. When the movable locking plate 6 is pushed to rotate, the movable locking plate 6 rotates around the rotation axis of the pawl 5. Since the opening direction of the locking groove 61 is perpendicular to the rotation axis of the pawl 5, the opening of the locking groove 61 can avoid the push rod 71 rotating relative to the movable locking plate 6, ensuring that the helical motion of the push rod 71 can be converted into the rotation of the pawl 5.

[0043] Furthermore, a shim 73 is provided between the movable plate 6 and the fixed plate 72. The shim 73 is fitted onto the smooth rod section 711, and the inner diameter of the shim 73 is smaller than the inner diameter of the locking groove 61. The inner diameter of the locking groove 61 is larger than the inner diameter of the shim 73, thereby further increasing the gap between the locking groove 61 and the smooth rod section 711. This further prevents motion interference between the pushing rod 71 and the movable plate 6 when the stepped surface pushes the movable plate 6. The shim 73 is relatively thin, and the shim 73 can tilt at a large angle relative to the pushing rod 71, thus preventing motion interference between the shim 73 and the pushing rod 71.

[0044] The push rod 71 also includes a limiting section 713, which is located at the end of the smooth rod section 711 away from the threaded section 712. A limiting nut 714 is threadedly connected to the limiting section 713, and the limiting nut 714 is located on the side of the movable clamping plate 6 away from the fixed clamping plate 72. The limiting nut 714 on the limiting section 713 can limit the movable clamping plate 6 and prevent the movable clamping plate 6 from coming off the push rod 71.

[0045] like Figure 7 and Figure 8 As shown, to facilitate rotation of the push rod 71, the push rod 71 further includes a connector 715. The connector 715 is located at the end of the threaded section 712 away from the smooth rod section 711, and a handle 74 is connected to the connector 715. After the handle 74 is connected to the connector 715, the push rod 71 can be rotated by operating the handle 74, which facilitates operation.

[0046] The connector 715 has several engagement slots 716, and the handle 74 is connected to several engagement pins 741, with the engagement pins 741 and engagement slots 716 corresponding to each other.

[0047] To ensure the strength of the fixing buckle, a pad 12 is provided inside the cable groove 11. The pad 12 thickens the cable groove 11, increasing its strength and preventing the steel cable 4 from damaging the cable groove 11 when tightened. The cross-sectional shape of the cable groove 11 is arc-shaped to avoid stress concentration.

[0048] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
