Description

Technical Field

[0001] The invention relates to the technical field of freight bundling, in particular to a novel bundling belt tightener. Background Art

[0002] During the freight transportation process, it is usually necessary to tie the goods to prevent them from falling off or colliding. Traditionally, goods are tied directly with ropes. Although this method has good versatility, the tying process is time-consuming and labor-intensive, and it is difficult to tie the goods tightly.

[0003] In order to solve the shortcomings of traditional cargo bundling methods, bundling tighteners are often used to fix cargoes. Conventional bundling tighteners on the market include an adjustable bundling belt tightening and locking mechanism with Chinese patent publication number CN117819056A, or a ratchet-type bundling device with pre-tightening force with publication number CN 213832237 U. The principles of the two are similar, with one section of the rope fixed on a carrier and the other section wound on a rotating shaft with a ratchet. After the two sections of the rope are fixed, the ratchet on the rotating shaft is turned by a handle to continuously wind up the active section of the rope to achieve the bundling and tightening effect.

[0004] However, the existing binding belt tighteners such as the above have the following shortcomings: First, since one section of the rope is fixed, when the two sections of the rope are tied, the tightener is located at a fixed point, and the rope of the fixed section is often shorter, which results in the main part of the tightener often being located near the fixed section of the rope, which is also the side of the cargo, and the tightener is pressed against the cargo near the fixed point of the fixed section of the rope and cannot be moved, and often due to the limited scene, it will touch other cargo or carriers. Second, when the tightener is located near the fixed section of the rope, the length of the fixed section is much shorter than the length of the movable section, which results in uneven tightening force on both sides, which easily leads to greater pressure on the rope on the movable side.

[0005] Based on the above-mentioned defects of the existing tighteners, this case arises. Summary of the invention

[0006] 1. Technical issues to be resolved

DETAILED DESCRIPTION

[0030] The embodiment of the present invention provides a novel binding belt tightener, such as Figure 1-9 As shown, it includes a support 1, a winding shaft 2 for winding up the first section of the fixed rope, a winding shaft 3 for winding up the second section of the fixed rope, a first-axis clamping plate 5, a second-axis clamping plate 6, and a handle 7.

[0031] like Figure 3 As shown, the reel 1 2 and the reel 2 3 are pivotally connected to the bracket 1, and the reel 1 2 and the reel 2 3 are arranged side by side. The reel 1 2 and the reel 2 3 are both hollow and have an opening. The reel 1 2 and the reel 2 3 are coaxially provided with an inner shaft 21, and the inner shaft 21 is used to sleeve the end of the fixing rope. The fixing rope extends out of the opening of the reel and is wound on the reel. The fixing rope on the reel 1 2 is wound clockwise, and the fixing rope on the reel 2 3 is wound counterclockwise.

[0032] like Figure 2 As shown, ratchet 1 4 and ratchet 2 12 are coaxially arranged on winding shaft 1 2 and winding shaft 2 3, respectively, wherein ratchet 2 12 is a conventional ratchet with a circle of ratchet 2 13 arranged outside. Ratchet 1 2 is improved on the conventional ratchet, with a circle of ratchet 1 41 arranged outside, and a concave limit slot 42 is arranged at the connection between two adjacent ratchet 1 41.

[0033] like Figure 1 As shown, two clockwork spring boxes 14 are arranged on the outer side of the support 1, and the two clockwork spring boxes 14 correspond to the winding shaft 1 2 and the winding shaft 2 3 respectively. The winding shaft 1 2 and the winding shaft 2 3 are coaxially connected to the clockwork shaft at the center of the clockwork spring box 14, and a clockwork spring is wound on the clockwork shaft. The inner end of the clockwork spring is fixedly connected to the clockwork shaft, and the outer end is fixedly connected to the inner wall of the clockwork spring box 14.

[0034] When the fixed rope is pulled out of the winding shaft 1 2 and the winding shaft 2 3, the winding spring can be linked to wind up. The winding spring is used to provide a certain pre-tightening force when the fixed rope is retracted, so as to facilitate the recovery of the fixed rope.

[0035] like Figure 2As shown, the shaft clamping plate 5 is movably arranged on the support 1 along the radial direction of the winding shaft 2, and corresponds to the pawl 41 of the ratchet 4. A connecting rod 51 is arranged at the tail of the shaft clamping plate 5, and a slideway 52 for the connecting rod 51 to slide is arranged on the support 1. A spring 53 is sleeved on the connecting rod 51. The spring 53 is used to support the shaft clamping plate 5. When there is no external force, the distance between the end of the shaft clamping plate 5 and the axis of the winding shaft 2 is less than the outer diameter of the pawl 41, and greater than the inner diameter of the pawl 41. The shaft clamping plate 5 will not enter the limit slot 42.

[0036] like Figure 1 As shown, the two-axis clamping plate 6 is movably arranged on the support 1 along the radial direction of the second winding shaft 3, and corresponds to the second pawl 13 of the second ratchet 12. The two-axis clamping plate 6 is arranged horizontally, and a slide groove is horizontally provided on the support 1. The end of the two-axis clamping plate 6 is provided with a slider that is slidably adapted in the slide groove. A receiving groove is provided on the support 1, and a column 61 is vertically provided in the receiving groove. A torsion spring 62 is sleeved on the column 61. A fixing hole 63 is provided on the two-axis clamping plate 6, and the two end rods of the torsion spring 62 are respectively against the support 1 and the fixing hole 63. The torsion spring 62 is used to support the two-axis clamping plate 6. When there is no external force, the end of the two-axis clamping plate 6 does not contact the second pawl 13 of the second ratchet 12.

[0037] The handle 7 is rotatably arranged on the support 1 and is coaxially arranged with the winding shaft 2, but the handle 7 and the winding shaft 2 are independent of each other and do not interfere with each other when rotating. A locking mechanism for locking the ratchet 4 is arranged on the handle 7.

[0038] like Figure 1 As shown, the locking mechanism includes a shift plate 10 and a guide plate 9. A slide column 101 is provided at the tail of the shift plate 10. A slide cavity 102 for the slide column 101 to slide is provided on the handle 7. The slide cavity 102 is arranged along the radial direction of the winding shaft 2. A spring 103 is sleeved on the slide column 101. The spring 103 is used to provide tensioning force for the shift plate 10. The paddle plate 10 can be inserted into the limiting slot 42 under the action of the spring 2 103. The guide plate 19 is arranged on the support 1 and is located on the outside of the ratchet 4. An initial positioning slot 91, an adjusting arc segment 92, and a locking positioning slot 93 are arranged on the outer edge of the guide plate 9 in a clockwise direction. The adjusting arc segment 92 is in an arc shape and is concentric with the winding shaft 2. The initial positioning slot 91 and the locking positioning slot 93 are concave slots. A guide block 11 is arranged on the side of the paddle plate 10 and can slide along the length direction of the outer edge of the guide plate 9. When the guide block 11 is located in the initial positioning slot 91, the paddle plate 10 is not in contact with the ratchet 4. When the guide block 11 is located in the adjusting arc segment 92 or the locking positioning slot 93, the paddle plate 10 can be inserted into the limiting slot 42.

[0039] like Figure 5As shown, a linkage mechanism is also provided on the handle 7 . When the guide block 11 is located in the adjustment arc segment 92 or the locking positioning groove 93 , the linkage mechanism can synchronously push the second axis clamping plate 6 to clamp the pawl 13 of the second ratchet wheel 12 .

[0040] like Figure 5 As shown, the linkage mechanism includes a guide plate 2 8, which is arranged on the handle 7 and arranged coaxially with the reel 1 2. The outer ring of the guide plate 2 8 is provided with a protruding section 81 and a recessed section 82 in a clockwise direction. The protruding section 81 is a regular arc shape, and the protruding section 81 is arranged coaxially with the reel 1 2. The recessed section 82 can be an arc shape or a flat surface with a diameter smaller than the protruding section 81, and is not specifically limited. The distance between its outer edge and the axis of the reel 1 2 is smaller than the distance between the outer edge of the protruding section 81 and the axis. When the guide block 11 is located in the initial positioning groove 91, the recessed section 82 contacts the second axis clamping plate 6, and the second axis clamping plate 6 does not contact the second ratchet 13 at this time. When the guide block 11 is located in the adjustment arc section 92 or the locking positioning groove 93, the protruding section 81 contacts the second axis clamping plate 6, and the second axis clamping plate 6 is clamped between two adjacent ratchet 2 13.

[0041] The working principle is divided into three states:

[0042] State 1 is the initial state, at this time, the handle 7 is turned to Figure 4 At the same time, the guide block 11 is moved to the initial positioning groove 9 with the assistance of the operator. Figure 5 As shown, the paddle 10 does not contact the ratchet wheel 1 4, and the second axis clamping plate 6 does not contact the ratchet wheel 2 12. In this state, the fixing ropes wound on the reel 1 2 and the reel 2 3 can be freely extended to fix the goods, and the position of the support 1 can be adjusted by retracting and releasing the two fixing ropes according to the actual scene, so that the support 1 is placed in the best position.

[0043] State 2 is the tightening operation state. When the fixed rope has initially tied the goods, the operator pulls the guide block 11 out of the initial positioning groove 91, and then rotates the handle 7 to Figure 6 The guide block 11 enters the adjustment arc section 92. Figure 7 As shown, the dial plate 10 is inserted into the limit slot 42, and the second axis clamping plate 6 is pressed into the ratchet 13 under the pressure of the protruding section 81, so that the reel 2 3 is limited counterclockwise. At this time, the handle 7 can be rotated counterclockwise for multiple times to drive the reel 1 2 to rotate counterclockwise to reel the excess loose fixed rope on the reel 1 2 to tighten the binding fixed rope, and the first axis clamping plate 5 provides a one-way lock for the ratchet 1 4 during the tightening operation. When the handle 7 rotates clockwise, the first axis clamping plate 5 locks the clockwise rotation of the ratchet 1 4, so that the handle 7 can reciprocate and drive the reel 2 to rotate counterclockwise.

[0044] State three is the locking state. When the fixing rope is tightened, the handle 7 is rotated to Figure 8 The position shown in FIG. 1 is when the guide block 11 enters the locking positioning groove 93. Fig. 9 As shown, the shift plate 10 is clamped into the limit clamping groove 42 of the ratchet wheel 1 4 under the action of the spring 2 103, thereby completely locking the ratchet wheel 1 4. The second shaft clamping plate 6 is still pressed by the protruding section 81 to the deepest part between the two ratchet claws 2 13, so that the reel shaft 2 3 is completely locked in the counterclockwise direction.

[0045] When untying the fixed rope, just reset the handle 7 to the position as shown in the figure. Figure 4 The location shown is OK.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
