Description

Technical Field

[0001] The utility model relates to a cable installation tool, in particular to a wire-pulling pulley. Background Art

[0002] A wire-pulling pulley generally includes a mounting seat, two baffles fixed to the mounting seat, a pulley rotatably arranged between the two baffles, a connecting block fixed between the two baffles, and a self-locking hook connected to the connecting block. Both of the two baffles are provided with arc segments, which cooperate with the pulley to form a wire-pulling area. The arc segment of one of the baffles is hinged to the straight segment for connecting the pulley on itself, and the fixation between the arc segment and the connecting block can be released. After the release, by swinging the arc segment away from the connecting block, the wire-pulling area can be opened. Correspondingly, by swinging the arc segment close to the connecting block and then fixing the two, the wire-pulling area can be closed. In the existing wire-pulling pulley, the arc segment and the connecting block are generally connected by bolts, resulting in relatively complicated and inconvenient operations when the arc segment and the connecting block are fixedly connected or the fixed connection is released. Content of the Utility Model

[0003] This application provides a wire-pulling pulley, which can solve the problems put forward in the background art.

[0004] In this application, a wire-pulling pulley is provided, including:

[0005] A mounting seat, in a U shape, and a plurality of first bolts are threadedly connected to the side plate on the concave side;

[0006] A first baffle, fixedly connected to the outer wall of the other side plate of the mounting seat, and sequentially including: an integrated first straight segment, a first arc segment, and a second straight segment;

[0007] A connecting block, with the first side fixedly connected to the second straight segment;

[0008] A second baffle, fixedly connected to the outer wall of the other side plate of the mounting seat, and sequentially including: a third straight segment, a second arc segment, and a fourth straight segment; wherein the second arc segment and the fourth straight segment are integrally arranged and hinged to the third straight segment;

[0009] A pulley, rotatably connected to the first straight segment and the third straight segment;

[0010] A plug pin, slidably connected to the fourth straight segment, and can extend out or retract from the side of the fourth straight segment close to the connecting block; a jack for cooperating with the plug pin is arranged on the second side of the connecting block opposite to the first side;

[0011] An elastic member, arranged between the plug pin and the fourth straight segment, so that the plug pin extends out from the side of the fourth straight segment close to the connecting block;

[0012] A self-locking hook, connected to the connecting block.

[0013] Further, one end of the bolt entering the jack has a protrusion that can restrict the bolt from leaving the jack; the bolt can also rotate relative to the fourth straight segment, and the restriction formed between the protrusion and the jack can be released through this rotation.

[0014] Further, the other end of the bolt has a mark corresponding to the protrusion.

[0015] Further, the cross-sections of the first baffle and the second baffle are both concave.

[0016] Further, the mounting seat is provided with a connecting plate for the first straight segment and the third straight segment to be sleeved into.

[0017] Further, the pulley is rotatably connected to the first straight segment and the third straight segment through a second bolt and a nut, and the second bolt and the nut respectively abut against the top edges of the two connecting plates.

[0018] In summary, in the present application, a wire-releasing pulley includes a mounting seat, a first baffle, a connecting block, a second baffle, a pulley, a bolt, an elastic member, and a self-locking hook. Manually overcoming the elastic member to retract the bolt into the vicinity of the fourth straight segment and releasing the connection with the connecting block allows the second arc segment and the fourth straight segment to swing, enabling the wire-releasing area between the first arc segment and the second arc segment to be opened or closed. When the wire-releasing area between the first arc segment and the second arc segment is in a closed state, the bolt resumes protruding from the side close to the connecting block of the fourth straight segment and enters the jack of the connecting block, restricting the swinging of the second arc segment and the fourth straight segment and keeping the wire-releasing area between the first arc segment and the second arc segment in a closed state. It has the beneficial effects of simple structure, stable connection, and quick and convenient operation. Description of the Drawings

[0036] Please refer to Figure 1 and Figure 2 , a wire-releasing pulley, comprising a mounting base 1, a first baffle 2, a connecting block 3, a second baffle 4, a pulley 5, a pin 6, an elastic member 7 and a self-locking hook 8.

[0037] The mounting base 1 is U-shaped, and a number of first bolts 1a are threadedly connected to the side plate on the concave side. More specifically, through holes with internal threads can be provided on this side plate, and there can be two first bolts 1a.

[0038] The first baffle 2 is fixedly connected to the outer wall of the other side plate of the mounting base 1. More specifically, they can be fixedly connected by welding. The first baffle 2 sequentially includes an integrated first straight section 2a, a first arc section 2b, and a second straight section 2c.

[0039] The first side of the connecting block 3 is fixedly connected to the second straight section 2c of the first baffle 2.

[0040] The second baffle 4 is also fixedly connected to the outer wall of the other side plate of the mounting base 1. The first baffle 2 sequentially includes a third straight section 4a, a second arc section 4b, and a fourth straight section 4c. Among them, the second arc section 4b and the fourth straight section 4c are integrally arranged and hinged to the third straight section 4a. That is, by swinging the second arc section 4b and the fourth straight section 4c, the wire release area between the first arc section 2b and the second arc section 4b can be opened or closed.

[0041] The pulley 5 is rotatably connected to the first straight section 2a and the third straight section 4a. More specifically, through holes are provided on both the first straight section 2a and the third straight section 4a, and a sleeve for connecting the pulley 5 is also provided between the first straight section 2a and the third straight section 4a. The second bolt 5a sequentially passes through the first straight section 2a, the sleeve, and the third straight section 4a, and the protruding part is threadedly connected with a nut 5b.

[0042] Please refer to Figure 1 , in some embodiments, the cross-sections of the first baffle 2 and the second baffle 4 are both concave-shaped. This improves the strength of the first baffle 2 and the second baffle 4.

[0043] Please refer to Figure 6 , further, the mounting base 1 is provided with a connecting plate 1b for the first straight section 2a and the third straight section 4a to be sleeved into. This positions the installation of the first baffle 2 and the second baffle 4 on the mounting base 1.

[0044] Furthermore, in combination with the above, the pulley 5 is rotatably connected to the first straight section 2a and the third straight section 4a through the second bolt 5a and the nut 5b. The second bolt 5a and the nut 5b respectively abut against the top edges of the two connecting plates 1b. That is, both the second bolt 5a and the nut 5b are hexagonal. Correspondingly, the first baffle 2 and the second baffle 4 can be installed on the mounting base 1 not by welding but by screws to the corresponding connecting plates 1b. After the first baffle 2 and the second baffle 4 are installed on the mounting base 1, the rotation of the second bolt 5a and the nut 5b is restricted by the connecting plate 1b to prevent the second bolt 5a and the nut 5b from loosening.

[0045] Please refer to Figure 2and Figure 3 The bolt 6 is slidably connected to the fourth straight segment 4c and can extend out or retract from the side of the fourth straight segment 4c close to the connecting block 3, that is, the fourth straight segment 4c is provided with a through hole for the bolt 6 to pass through. A jack 3a for mating with the bolt 6 is provided on the second side of the connecting block 3 opposite to the first side.

[0046] The elastic member 7 is disposed between the bolt 6 and the fourth straight segment 4c, so that the bolt 6 extends from the side of the fourth straight segment 4c close to the connecting block 3. More specifically, on the side of the fourth straight segment 4c away from the connecting block 3, a connecting sleeve 4c1 is fixedly connected; the bolt 6 passes through the connecting sleeve 4c1, and a stopper 6a with a larger outer diameter is integrally provided on the part of the bolt 6 inside the connecting sleeve 4c1; the elastic member 7 is a compression spring, sleeved on the bolt 6, one end is kept against the stopper 6a, and the other end is kept against the annular inner wall of the connecting sleeve 4c1 away from the fourth straight segment 4c.

[0047] Manually overcome the elastic member 7 to retract the bolt 6 into the fourth straight segment 4c, release the connection with the connecting block 3, and then the second arc segment 4b and the fourth straight segment 4c can be swung, so that the wire releasing area between the first arc segment 2b and the second arc segment 4b can be opened or closed. When the wire releasing area between the first arc segment 2b and the second arc segment 4b is in a closed state, the bolt 6 resumes extending from the side of the fourth straight segment 4c close to the connecting block 3 and enters the jack 3a of the connecting block 3, restricting the swinging of the second arc segment 4b and the fourth straight segment 4c, so that the wire releasing area between the first arc segment 2b and the second arc segment 4b remains in a closed state.

[0048] Please refer to Figure 1 and Figure 2 The self-locking hook 8 is connected to the connecting block 3.

[0049] Please refer to Figure 4 and Figure 5 In some embodiments, one end of the bolt 6 entering the jack 3a is provided with a protrusion 6b that can limit the bolt 6 from leaving the jack 3a. More specifically, the jack 3a includes a first hole 3a1 with a smaller aperture and a second hole 3a2 with a larger aperture, and a notch 3a3 for mating with the protrusion 6b and communicating with the second hole 3a2 is provided on the inner wall of the first hole 3a1. The bolt 6 can also rotate relative to the fourth straight segment 4c, and the restriction formed between the protrusion 6b and the jack 3a can be released through this rotation.

[0050] In this way, the connection between the bolt 6 and the connecting block 3 can be more stable, making the wire releasing area between the first arc segment 2b and the second arc segment 4b more stably maintained in a closed state.

[0051] Furthermore, the other end of the bolt 6 is provided with a mark 6c corresponding to the protrusion 6b, which is convenient for judging the position of the protrusion 6b in the jack 3a.
