[0027] Reference Figure 1-8 The utility model provides a rebar tying hook which is easy to adjust, comprising:
[0028] The lashing hook body 1 includes a sleeve 11;
[0029] The adjusting mechanism 2 includes an adjusting handle 21, and the inner surface of the adjusting handle 21 is sleeved on the outer surface of the sleeve 11;
[0030] The fixing device 3 includes a connecting column 31 , and the outer surface of the bottom end of the connecting column 31 is fixedly connected to the outer surface of the top end of the adjusting handle 21 .
[0031] Furthermore, the tying hook body 1 also includes an adjustment hole 12, and the adjustment hole 12 is provided with three groups, and the three groups of adjustment holes 12 are evenly provided inside the outer surface of one side of the sleeve 11, and the outer surface of the other side of the sleeve 11 is fixedly connected with a positioning strip 13, and the inner surface of the sleeve 11 is fixedly connected with a bearing 14, and the bearing 14 is provided in two groups, and the two groups of bearings 14 are respectively distributed at the upper and lower ends of the inner surface of the sleeve 11, and the inner surface of the bearing 14 is fixedly connected with a hook handle 15, and the inner surfaces of the two groups of bearings 14 are respectively fixedly connected to the upper end and the middle part of the outer surface of the hook handle 15, according to Figure 3 and Figure 4 As shown, the sleeve 11 is bearing-connected to the hook handle 15 through two sets of bearings 14. When the device is in use, the hook handle 15 can rotate, and the sleeve 11 will not rotate along with it.
[0032] Furthermore, the adjustment mechanism 2 also includes a positioning groove 22, and the positioning groove 22 is opened inside the inner wall surface of one side of the adjustment handle 21, and the size of the positioning groove 22 is the same as the size of the positioning strip 13, the outer surface of the positioning strip 13 is engaged with the inside of the positioning groove 22, and an insertion groove is opened inside the outer surface of the bottom end of one side of the adjustment handle 21, and an adjustment pin 23 is inserted inside the insertion groove, and a limiting ring is provided at one end of the adjustment pin 23, and a cylindrical block is provided at the other end of the adjustment pin 23, and the diameter of the cylindrical block is the same as the diameter of the adjustment hole 12, and a first spring 24 is sleeved on the outer surface of the middle part of the adjustment pin 23, according to Figure 5 and Figure 6 As shown, the positioning strip 13 is engaged with the inside of the positioning groove 22. When the sleeve 11 is pulled out, the sleeve 11 is restricted from moving up and down, and the sleeve 11 will not rotate inside the adjustment handle 21. The limiting ring at one end of the adjustment pin 23 prevents the adjustment pin 23 from falling off from the inside of the adjustment handle 21.
[0033] Furthermore, a receiving groove is provided on the inner surface of the insertion groove, and the outer diameter of the receiving groove is the same as the outer diameter of the cylindrical block, and the two ends of the first spring 24 are respectively against one side surface of the inner surface of the receiving groove and one side surface of the cylindrical block. Figure 6 As shown, the adjusting pin 23 is pulled to engage the cylindrical block into the receiving groove. The cylindrical block engages the fixed sleeve 11 and the telescopic length of the adjusting handle 21 by inserting into the adjusting holes 12 at different positions. When the adjusting pin 23 moves to one end, the cylindrical block squeezes the first spring 24. When the adjusting pin 23 is released from squeezing, the first spring 24 pushes the adjusting pin 23 to reset itself.
[0034] Furthermore, the fixing device 3 also includes a slider 32, and the slider 32 is sleeved on the outer surface of the connecting column 31, and the outer surface of the top of the connecting column 31 is fixedly connected with a semicircular block 33, the outer surface of the semicircular block 33 is sleeved with a fixed base 34, and a clamping block 35 is inserted inside the outer surface of the fixed base 34, and the clamping block 35 is provided in two groups, and the two groups of clamping blocks 35 are respectively inserted inside the outer surfaces of both ends of the fixed base 34, and a limiting block is provided on the outer surface of one end of the clamping block 35, and the other end of the clamping block 35 is set to an inverted trapezoid, the outer surface of the middle part of the clamping block 35 is sleeved with a second spring 36, and the outer surface of the top of the fixed base 34 is fixedly connected with a connecting ring 37, according to Figure 7 and Figure 8 As shown, the limit block at one end of the locking block 35 prevents itself from being separated from the interior of the fixed base 34, and the inverted trapezoid at the other end of the locking block 35 allows the semicircular locking block 33 and the connecting column 31 to push the two groups of locking blocks 35 to move to both sides and squeeze the second spring 36 when they move upward, so that when the locking block 35 is separated from the squeezing, the second spring 36 can push the locking block 35 to its original position through its own elasticity.
[0035] Furthermore, the height dimension of the connecting column 31 is greater than the height dimension of the slider 32, and the diameter dimension of the outer surface of the upper end of the slider 32 is the same as the diameter dimension of the outer surface of the lower end of the semicircular block 33. Figure 7 and Figure 8 As shown, the slider 32 moves up to a position where it fits with the semicircular block 33 , and the adjustment handle 21 is pulled down so that the semicircular block 33 is separated from the interior of the fixed base 34 , and the locking block 35 will not be locked between the semicircular block 33 and the slider 32 .
[0036] Working principle: First, adjust the length of the binding hook body 1 and the adjustment mechanism 2 according to the required binding position, first pull the limit ring on the adjustment pin 23 outward, and pull the cylindrical block at the other end of the adjustment pin 23 out of the adjustment hole 12. The positioning bar 13 is engaged with the inside of the positioning groove 22 to limit the sleeve 11 from rotating inside the adjustment handle 21. Then pull the adjustment handle 21 down. When the appropriate adjustment hole 12 is in the corresponding position of the adjustment pin 23, relying on the elasticity of the first spring 24, the cylindrical block at the other end of the adjustment pin 23 can be reset and inserted into the inside of the adjustment hole 12. The sleeve 11 is adjusted and fixed, thereby fixing the length of the equipment. Then use the bottom end of the hook handle 15 for binding. When the hook handle 15 rotates, the two sets of bearings 14 prevent other parts of the equipment from rotating with it.
[0037] The fixing device 3 is connected to the worker through the connecting ring 37. After the tying work is completed, the adjusting handle 21 is held to push the semicircular block 33 into the fixed base 34. The surfaces on both sides of the semicircular block 33 push the two sets of snap blocks 35 to both sides and squeeze the second spring 36. When the lower end of the semicircular block 33 exceeds the position of the upper end of the snap block 35, the snap block 35 is elastically reset by the second spring 36 and snapped to the lower surface of the semicircular block 33, so that the position of the equipment can be fixed. When it is used next time, The adjusting handle 21 is held by hand to push the slider 32 into the fixed base 34, and the upper end surface of the slider 32 pushes the two groups of engaging blocks 35 to both sides. When the upper end of the slider 32 exceeds the position of the upper end of the engaging blocks 35, the adjusting handle 21 is pulled down so that the two groups of engaging blocks 35 push the slider 32 along the connecting column 31 against the semicircular engaging block 33, and then the side surface of the slider 32 pushes the two groups of engaging blocks 35 to both sides, and then the device can be removed for use by pulling it down again. The above is the entire working principle of the utility model.
