[0058] refer to Figure 3-14 , an embodiment of the present invention shows a hand-held cord lock device C0, which is arranged on the top of the lifter and includes a frame 200, a hand-held unit C1, a lock reset unit C2 and an unlocking unit C3;
[0059] refer to Figure 4-6 The frame 200 is provided with a first slide 210; the portable unit C1 includes a carrying handle C11, the carrying handle C11 is connected to a connecting arm C12, the connecting arm C12 is connected to a cord lock assembly C13 at one end away from the carrying handle C11, and the carrying handle C11 is provided with a rope fixing assembly C14 for connecting a rope 300; the cord lock assembly C13 and at least part of the connecting arm C12 are slidably disposed in the first slide 210; the lock reset unit C2 The slide is set in the first slide 210, and the lock reset unit C2 includes a sliding base C21. The sliding base C21 is provided with a locking mechanism C22 and a first elastic member C23. The locking mechanism C22 is snap-connected with the rope lock assembly C13. The first elastic member C23 is used to provide the sliding base C21 with a force to move toward the bottom end of the first slide 210; the unlocking unit C3 is used to disengage the locking mechanism C22 and the rope lock assembly C13.
[0060] Simply put, the portable cord lock device C0 has both a portable function and a cord lock function. In the initial state, the portable unit C1 is connected to the frame 200 through the lock reset unit C2. The portable unit C1 can be used to lift the frame 200 and the entire lifter, making it easy to carry. When a lifting operation is required, the portable unit C1 can be pulled out of the frame 200, and the cord lock assembly C13 on the portable unit C1 can be locked with the rope 300 to fix the rope 300 to a high-altitude fixed object.
[0061] In addition, to facilitate understanding of the working process and advantages of the hand-carrying cord lock device C0, the working process of the hand-carrying cord lock device C0 is described in detail when applied to a lifter;
[0062] refer to Figure 1 and Figure 2 , shows a lifter, which includes a frame 200, a rope winding shaft 100 rotatably arranged on the frame 200, and a rope 300 wound on the rope winding shaft 100; wherein the rope winding shaft 100 is driven to rotate by a driving device (not shown) to realize rope collection and release; a shell 400 is provided on the frame 200, and the shell 400 has an outlet (not marked in the figure) for the rope 300 to enter and exit, and the hand-held rope buckle device C0 is provided near the outlet.
[0063] The frame 200 is disposed in the housing 400, and the hand-carrying unit C1 and the lock reset unit C2 of the hand-carrying cord lock device C0 are disposed in the first slide 210 of the frame 200. Therefore, at least a portion of the hand-carrying cord lock device C0 is embedded in the lifter; Figure 1 As shown, in this embodiment, in the initial state, the hand-carrying cord lock device C0 is completely embedded in the lifter.
[0064] Specifically, in the initial state, the cord lock assembly C13 on the portable unit C1 is snap-connected with the lock mechanism C22 of the lock reset unit C2, and the first elastic member C23 drives the sliding base C21 to move toward the bottom end of the first slideway 210. Figure 6 As shown, in the absence of external force, the hand-held unit C1 is embedded in the lifter, so that the hand-held cord lock device C0 is not easily collided, thereby avoiding affecting the connection structure between the hand-held cord lock device C0 and the rope 300 and preventing the rope 300 from being easily worn.
[0065] When the lifter is needed by hand, the carrying handle C11 can be pulled upward. The pulling force on the carrying handle C11 will resist the elastic force of the first elastic member C23, so that the carrying unit C1 and the lock reset unit C2 are both moved upward along the first slide 210, so that at least a portion of the carrying unit C1 is exposed outside the lifter, at least the carrying handle C11 is completely exposed outside the lifter for easy grasping; when the lifter is not needed by hand, the carrying handle C11 is released. Under the action of the first elastic member C23, the carrying unit C1 and the lock reset unit C2 are reset, that is, they descend along the first slide 210, so that the carrying unit C1 is re-embedded in the lifter.
[0066] When lifting is required, the unlocking unit C3 can be used to release the buckle of the lock mechanism C22 on the cord lock assembly C13, so that the portable unit C1 is separated from the lock reset unit C2. At this time, the portable unit C1 can be pulled out from the first slide 210. The state of the portable unit C1 after being pulled out is as follows: Figure 4 Afterwards, the portable unit C1 can be wound and tied with the rope 300, as shown Figure 14 As shown, assuming that the end of the rope 300 is to be fixed to the railing of the rooftop of a building, the portable unit C1 can be wound around the railing at least once, and then the rope lock assembly C13 can be used to lock it to the rope 300, so that the rope 300 is wound and tied to the fixed object.
[0067] In some embodiments, as Figure 4 As shown, the rope lock assembly C13 includes a locking hook C131, a locking hole C132 is formed in the locking hook C131, and a side opening for the rope 300 to enter is provided on one side of the locking hole C132, and a blocking piece C133 for blocking the side opening (not marked in the figure) is hinged on the locking hook C131; wherein, a torsion spring is provided between the blocking piece C133 and the locking hook C131, and the torsion spring enables the blocking piece C133 to keep blocking the side opening, so that the rope 300 can enter the locking hole C132 from the outside, but is difficult to leave from the locking hole C132; it should be noted that the rope lock assembly C13 shown in this embodiment is a conventional rope lock structure. In other embodiments, other rope lock structures that can be connected to the rope 300 can also be used.
[0068] In some embodiments, in order to facilitate the buckle connection between the locking mechanism C22 and the cord lock assembly C13, refer to Figure 5-8The locking mechanism C22 includes a locking tongue C221, the middle portion of which is rotatably connected to the sliding base C21 via a hinge shaft C222. A hook portion C2211 for hooking into the lock hole C132 of the cord lock assembly C13 is provided on the side of the first end of the locking tongue C221, and a prying portion C2212 is formed on the second end of the locking tongue C221. A locking torsion spring C223 for driving the hook portion C2211 to approach the cord lock assembly C13 is provided on the hinge shaft C222. The unlocking unit C3 is used to squeeze the prying portion C2212 to disengage the hook portion C2211 from the lock hole C132.
[0069] Among them, such as Figure 7 As shown, in the initial state, under the action of the lock torsion spring C223, the hook portion C2211 of the lock tongue C221 is hooked into the lock hole C132, so that the handheld unit C1 is connected to the lock reset unit C2; when the unlocking unit C3 squeezes the prying portion C2212, the lock tongue C221 will swing around the hinge axis C222, as shown in FIG. Figure 8 As shown, the hook portion C2211 leaves the lock hole C132, so that the portable unit C1 can be separated from the lock reset unit C2.
[0070] Among them, such as Figure 4 As shown, the side of the first slideway 210 is provided with an escape hole 220 for the lock tongue C221 to extend out. In this embodiment, the bracket, the handheld unit C1 and the lock reset unit C2 are compact in structure, avoiding adding unnecessary space in the first slideway 210, which is conducive to reducing the size of the lifter.
[0071] Preferably, reference Figure 6-8 The sliding base C21 is provided with a second slideway C211 having the same length as the first slideway 210. The second slideway C211 is provided with an opening at one end close to the cord lock assembly C13. A top block C212 is provided in the second slideway C211 for sliding. A second elastic member C213 is further provided in the second slideway C211 for pushing the top block C212 close to the cord lock assembly C13. The top block C212 is provided with a second elastic member C213 having a width greater than that of the second slideway at one end away from the opening of the second slideway C211. In this embodiment, when the unlocking unit C3 is triggered, the hook portion C2211 leaves the lock hole C132, and the second elastic member C213 pushes the top block C212 out, so that the top block C212 pushes the cord lock assembly C13 outward toward the first slideway 210. In this way, on the lifter, when the unlocking unit C3 is triggered, the hand-held unit C1 will pop up a short distance, allowing the user to clearly feel that the unlocking has been successful and to pull the hand-held unit C1 out.
[0072] In addition, if Figure 8 As shown, when the top block C212 is located in the extreme position of the second slideway C211 near the cord lock assembly C13, the hook portion C2211 of the lock tongue C221 is offset from the lock hole C132 and corresponds to the outer wall of the lock hook C131. In other words, after the top block C212 pushes the cord lock assembly C13 out, even if the unlocking unit C3 is released, the lock torsion spring C223 cannot re-engage the hook portion C2211 in the lock hole C132.
[0073] like Figure 6 As shown, the end face of the hook portion C2211 is formed with a matching inclined surface C2213. When the portable unit C1 is reinserted into the first slide 210, the lock of the cord lock assembly C13 squeezes the matching inclined surface C2213 of the hook portion C2211, causing the lock tongue C221 to swing, so that the hook portion C2211 is re-fastened into the lock hole C132, thereby fixing the portable unit C1.
[0074] In some embodiments, to facilitate unlocking, refer to Figure 3 and Figure 6 The unlocking unit C3 includes an unlocking button C31, a connecting rod assembly C32 and a third elastic member C33; the unlocking button C31 is connected to the first end of the connecting rod assembly C32, and the second end of the connecting rod assembly C32 is located on the outside of the prying portion C2212; when the unlocking button C31 is pressed, the second end of the connecting assembly forms an extrusion fit with the prying portion C2212; the third elastic member C33 is used to drive the unlocking button C31 to reset.
[0075] Among them, pressing the unlocking button C31 can unlock the locking mechanism C22; for ease of operation, the unlocking button C31 can be set on the surface of the housing 400 of the lifter, and the connecting component is used to enable the unlocking button C31 and the prying part C2212 to move in conjunction.
[0076] In some embodiments, to make the structure more compact, reference Figure 6-9The inner wall of the first slide 210 is provided with a guide groove 230, and the length direction of the guide groove 230 is the same as the length direction of the first slide 210. Two symmetrical guide surfaces 231 are formed on the two side walls of the guide groove 230, and the guide surfaces 231 are inclined, and the closer to the position of the rope lock component C13, the shorter the distance between the two guide surfaces 231; the first elastic member C23 includes a spiral elastic body C231, and the head and tail ends of the spiral elastic body C231 respectively extend out elastic arms C232, and the spiral elastic body C231 is arranged on the sliding base C21; the first elastic body is arranged in the guide groove 230, and the two elastic arms C232 respectively abut against the guide surfaces 231; wherein, when the first elastic member C23 moves toward the position of the rope lock component C13, the angle between the two elastic arms C232 becomes smaller.
[0077] Thus, the two elastic arms C232 of the first elastic member C23 cooperate with the two guide surfaces 231 in the guide groove 230 to achieve the reset action of the lock reset unit C2 back to the bottom of the first slideway 210. This embodiment occupies less space and makes the structure more compact.
[0078] In some embodiments, to improve the connection stability between the portable unit C1 and the rope 300, refer to Figure 10-13 The rope fixing assembly C14 includes a rope fixing base C141 and a rope pressing member C142; at least one rope releasing groove C1411 is recessed on both sides of the rope fixing base C141, and the rope releasing grooves C1411 on both sides are paired with each other. A rope hole C1412 is provided between the two paired rope releasing grooves C1411 to achieve communication between the two rope releasing grooves C1411, and a rope inlet hole C1413 is provided on the side of at least one of the two paired rope releasing grooves C1411 to communicate with the outside world; the rope pressing member C142 can The rope pressing member C142 is detachably arranged in the rope releasing groove C1411, and includes a rope pressing drum C1421 and a convex column C1422 located in the middle of the first end of the rope pressing drum C1421. A rope pressing channel C1414 is formed between the bottom surface of the rope releasing groove C1411, the inner side wall of the rope releasing groove C1411, the end surface of the first end of the rope pressing drum C1421 and the outer side wall of the convex column C1422; the end surface of the first end of the rope pressing drum C1421 and the bottom surface of the rope releasing groove C1411 clamp the rope 300.
[0079] Among them, the end of the rope 300 enters from the rope inlet hole C1413, then winds around the rope pressing channel C1414 in one of the rope release grooves C1411, and then enters the rope release groove C1411 on the other side through the rope passing hole C1412, and winds around the rope pressing channel C1414 again; the rope 300 itself does not overlap, so as to avoid the overlapping point of the rope 300 being easily cut by stress; the rope pressing drum C1421 of the rope pressing member C142 can press the rope 300 tightly against the bottom surface of the rope release groove C1411, and a rope 300 is pressed tightly by two rope pressing members C142 to ensure a stable connection.
[0080] In the above embodiment, the interior of the carrying handle C11 is hollow, and the rope-holding assembly C14 is disposed within the carrying handle C11. The carrying handle C11 is provided with an opening (not labeled in the figure) corresponding to the rope-entry hole C1413 of the rope-holding assembly C14. This improves the aesthetics of the carrying handle C11 and also shields and protects the rope-holding member C142 from external influences.
[0081] In the above solution, in order to facilitate installation, the rope pressing member C142 is fixed to the rope fixing base C141 by means of threaded fasteners.
[0082] Theoretically, the connecting arm C12 and the cord lock assembly C13 on the carrying handle C11 can be configured as one; however, in this embodiment, Figure 4 and Figure 14 As shown, both ends of the carrying handle C11 are provided with the connecting arm C12 and the cord lock assembly C13, so that the sense of balance when carrying is better.
[0083] In addition, according to the prior art CN112551413A, the rope 300 on the rope winding shaft 100 can be provided with multiple ropes. Even if part of the rope 300 breaks, the lifting object will not fall, thereby improving safety. Figure 14 In this embodiment, three ropes 300 are provided. The ropes 300 on both sides can be buckled on the rope lock components C13 on both sides respectively, and the middle rope 300 can be buckled on the rope lock component C13 on any side or not.
