[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] See also Figure 1-4 A wire-retracting and -releasing device for construction engineering comprises a protective shell 1, a handle 2 is fixedly connected to the top of the protective shell 1, a ratchet 6, a central shaft 7 and a limit cover 9 are connected to the inside of the protective shell 1, a construction wire 3 and a spring 8 are connected to the central shaft 7, the spring 8 collects the construction wire 3 on the central shaft 7, and a pawl 5 for locking the ratchet 6 is connected to the outer wall of the ratchet 6.
[0023] The handle 2 is inserted into the protective shell 1 and slides in the protective shell 1. A protrusion for limiting the handle 2 is fixedly connected to the handle 2 inside the protective shell 1. The handle 2 can be limited in the protective shell 1 by the protrusion connected to the handle 2. When the handle 2 moves upward to the upper part of the protective shell 1, the protrusion abuts against the inner wall of the protective shell 1, and the handle 2 cannot continue to move upward. The staff can hold the upper part of the handle 2 to move the protective shell 1. When the handle 2 moves downward, the bottom of the handle 2 extends out of the protective shell 1 and is inserted into the use place to fix the position of the protective shell 1, wherein the bottom of the handle 2 is conical.
[0024] The limiting cover 9 is fixed to one side of the protective shell 1, the mainspring 8 is clamped in the limiting cover 9, and the middle part of the limiting cover 9 is sleeved on one end of the central axis 7. By connecting the mainspring 8 in the limiting cover 9, the mainspring 8 is limited.
[0025] One end of the central shaft 7 is fixedly connected to the spring 8, the construction line 3 is wound around the middle of the central shaft 7, and the end of the central shaft 7 away from the limiting cover 9 is fixedly connected to the ratchet 6. The end of the construction line 3 away from the central shaft 7 passes through the front side of the protective shell 1. When the staff pulls the construction line 3 toward the outside of the protective shell 1, the construction line 3 drives the central shaft 7 to rotate, and the central shaft 7 drives the ratchet 6 and the spring 8 at both ends to rotate. At this time, the spring 8 is tightened, and the pawl 5 shakes on the ratchet 6. When the staff stops pulling the construction line 3, the ratchet 6 rotates in the opposite direction due to the elasticity of the spring 8, and the pawl 5 clamped in the ratchet 6 is limited. The reverse rotation retracts the construction line 3, which plays a role in limiting the construction line 3. The end of the construction line 3 away from the central shaft 7 is fixedly connected with a fixing cone for fixing the construction line 3. When not in use, it can also be inserted into the through hole opened on the front side of the protective shell 1 for collection, which greatly increases the practicality of the device.
[0026] A fixing column 10 is fixedly connected to the protective shell 1 on the side of the ratchet 6, and a pawl 5 and a spring member 11 are sleeved on the outer wall of the fixing column 10. One end of the pawl 5 is clamped on the outer wall of the ratchet 6. By connecting the pawl 5 and the spring member 11 on the fixing column 10, the resilience of the spring member 11 can limit the pawl 5, making the device more flexible when used.
[0027] One end of the pawl 5 away from the spring member 11 is fixedly connected to a connecting block 4, which passes through the protective shell 1 and slides in the protective shell 1. The pawl 5 inside the protective shell 1 can be moved by the connecting block 4 connected to the pawl 5, and the pawl 5 can be removed from the ratchet 6. The ratchet 6 can then rotate in the opposite direction under the action of the spring 8 to collect the construction line 3 on the central axis 7.
[0028] Working principle: When in use, the staff applies force to the handle 2 to fix the handle 2 at the place of use, and then pulls the construction line 3 out of the protective shell 1 to an appropriate length. At this time, the construction line 3 drives the ratchet 6 and the spring 8 at both ends to rotate through the central axis 7. When the staff stops pulling the construction line 3, the construction line 3 is fixed at the place of use through the fixed cone connected to the construction line 3, and the pawl 5 is clamped in the ratchet 6 to limit the position. After use, the staff presses the connecting block 4 to remove the pawl 5 from the ratchet 6. The ratchet 6 rotates in the opposite direction under the action of the spring 8 to collect the construction line 3 on the central axis 7. Finally, the staff pulls the handle 2 upwards and pulls the handle 2 out of the ground to move the device to another place of use.
[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
