Description

Technical Field

[0001] This utility model relates to the field of tensioner technology, and in particular to a ratchet tensioner with adjustable tightening direction. Background Technology

[0002] Securely fastening goods is a crucial step in the transportation, movement, loading, or storage of cargo. While traditional tensioners can meet the needs of securing goods to a certain extent, they still have some shortcomings in practical applications. For example, some tensioners can only be rotated in one direction to tighten, which limits their use. Therefore, there is a need to design a ratchet tensioner with adjustable tightening direction.

[0003] To address this, patent CN220227673U discloses a double-sided control ratchet tensioner with adjustable tightening direction, comprising a support plate, with support side tubes fixedly mounted at the bottom of both ends of the support plate, a ratchet body disposed at the center of the bottom of the support plate, and rotating tubes welded to the centers of both ends of the ratchet body. The support side tubes have rotating grooves inside. This double-sided control ratchet tensioner with adjustable tightening direction, through the arrangement of reinforcing blocks, through holes, support rods, grooves, and limiting bolts, allows the retaining rings at both ends of the double-sided control ratchet tensioner to have adjustable directional angles, making the ratchet tensioner suitable for various working environments, thus effectively improving the practicality of the ratchet tensioner. This design is simple in structure and easy to use. Furthermore, the combined use of the rotating tubes, movable threaded rods, and ratchet bodies allows users to easily adjust the length of the retaining rings, meeting the needs of existing users.

[0004] While the ratchet tensioner described above allows for easy adjustment of the tightening direction during use, it is inconvenient to lock the ratchet during the tightening process, which causes inconvenience in use. Therefore, it is necessary to design a ratchet tensioner with adjustable tightening direction. Utility Model Content

[0005] The purpose of this invention is to provide a ratchet tensioner with adjustable tightening direction, which solves the problem that existing ratchet tensioners are inconvenient to lock during the tightening process.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a ratchet tensioner with adjustable tightening direction, including a connecting plate;

[0007] The top of the connecting plate is fixed with an installation structure;

[0008] Both sides of the bottom end of the connecting plate are fixed with support plates, and the bottom of the support plates is provided with a tensioning structure.

[0009] A locking structure is fixed on the outer wall of one side of the support plate. The locking structure includes a movable block, a connecting shaft, a locking block, and a limiting block. The connecting shaft is fixed on the outer wall of one side of the support plate. A movable block is sleeved on the outer side of the connecting shaft. A locking block is fixed at the bottom of the movable block. A limiting block is fixed on one side of the locking block.

[0010] Furthermore, the side view of the locking block and the limiting block is triangular in shape.

[0011] Furthermore, the tensioning structure includes a ratchet gear, a rotating shaft, a limiting groove, a limiting plate, a retaining seat, and a rotating pin. The rotating shaft passes through the bottom of the support plate, and limiting grooves are provided on both sides inside the rotating shaft. The end of the rotating shaft near the movable block extends to the outside of the support plate and is fixed with the ratchet gear. The end of the rotating shaft away from the ratchet gear extends to the outside of the support plate and is fixed with the limiting plate. A retaining seat is fixed to the outside of the limiting plate, and a rotating pin is engaged inside the retaining seat.

[0012] Furthermore, the central axis of the ratchet disc and the central axis of the rotating shaft are collinear, and the central axis of the rotating shaft and the mounting bracket are collinear.

[0013] Furthermore, the side view of the rotating pin near the card seat end is shaped like a cross.

[0014] Furthermore, the mounting structure includes a mounting plate, a lead screw, a rotating handle, a clamping plate, and a positioning plate. The mounting plate is fixed to one side of the top of the connecting plate, and the positioning plate is fixed to the other side of the top of the connecting plate. Both sides of the interior of the mounting plate are threaded with lead screws. One end of each lead screw extends to the outside of the mounting plate and is rotatably connected to the clamping plate. The end of the lead screw away from the clamping plate is fixed with a rotating handle.

[0015] Furthermore, the lead screws are symmetrically distributed on both sides of the mounting plate, and the central axis of the lead screws and the central axis of the clamping plate are collinear.

[0016] The present invention provides an adjustable ratchet tensioner with the following advantages:

[0017] With a locking structure, the locking block and the limiting block can be easily reversed and unlocked by the rotational connection between the movable block and the connecting shaft. This allows for easy determination of whether the ratchet disc needs to be locked according to the actual situation, and easy control of the rotation direction of the ratchet disc as needed. This enables the device to have the function of easily locking the ratchet disc, and improves the convenience and applicability of the adjustable ratchet tensioner in use.

[0018] By setting a tensioning structure, the rotating pin and the card seat can be engaged and connected, and the rotating pin can rotate the card seat, thereby driving the rotating shaft to rotate. Under the limiting action of the limiting groove, one end of the rope can be wrapped and fixed inside the rotating shaft, realizing the function of easy rope locking of the device, and improving the working efficiency and convenience of the adjustable ratchet tensioner when using it.

[0019] With its mounting structure, the screw can be easily adjusted within the mounting plate due to the threaded connection between the screw and the mounting plate. The clamp can be easily moved closer to the component to be installed due to the rotatable connection between the screw and the clamp. This allows for easy installation on components of different thicknesses, thus improving the convenience of using the adjustable ratchet tensioner. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 The present invention provides a ratchet tensioner with adjustable tightening direction, including a connecting plate 1.

[0029] Reference Figures 1-6 The top of the connecting plate 1 is fixed with an installation structure 5. The installation structure 5 includes an installation plate 51, a lead screw 52, ​​a rotating handle 53, a clamping plate 54, and a positioning plate 55. The installation plate 51 is fixed to one side of the top of the connecting plate 1, and the positioning plate 55 is fixed to the other side of the top of the connecting plate 1. The two sides inside the installation plate 51 are threaded with lead screws 52. One end of each lead screw 52 extends to the outside of the installation plate 51 and is rotatably connected to the clamping plate 54. The end of the lead screw 52 away from the clamping plate 54 is fixed with a rotating handle 53. The lead screws 52 are symmetrically distributed on both sides of the installation plate 51, and the central axis of the lead screw 52 and the central axis of the clamping plate 54 are collinear.

[0030] During installation, first rotate the clamping plate 54 to one side of the mounting plate 51. Then, engage the mounting plate 51 and the positioning plate 55 at the bottom of the object to be installed. Next, rotate the lead screw 52. Since the lead screw 52 is threadedly connected to the mounting plate 51, the lead screw 52 will drive the clamping plate 54 closer to one side of the object to be installed. Continue rotating the lead screw 52 until one side of the clamping plate 54 and one side of the object to be installed come into contact with each other. This allows the device to be installed together with other objects. The contact action of the two sets of clamping plates 54 can improve the stability during installation.

[0031] Reference Figures 1-5 Support plates 2 are fixed on both sides of the bottom of the connecting plate 1. The bottom of the support plates 2 is provided with a tensioning structure 4. The tensioning structure 4 includes a ratchet gear 41, a rotating shaft 42, a limiting groove 43, a limiting plate 44, a locking seat 45, and a rotating pin 46. The rotating shaft 42 passes through the bottom of the support plate 2. Limiting grooves 43 are opened on both sides inside the rotating shaft 42. The end of the rotating shaft 42 near the movable block 31 extends to the outside of the support plate 2 and is fixed with the ratchet gear 41. The end of the rotating shaft 42 away from the ratchet gear 41 extends to the outside of the support plate 2 and is fixed with the limiting plate 44. A locking seat 45 is fixed on the outside of the limiting plate 44. The rotating pin 46 is engaged and connected inside the locking seat 45. The central axis of the ratchet gear 41 and the central axis of the rotating shaft 42 are collinear. The central axis of the rotating shaft 42 and the locking seat 45, and the side view of the rotating pin 46 near the locking seat 45 are in the shape of a cross.

[0032] Insert one end of the rotating pin 46 into the inside of the card holder 45. Since both the card holder 45 and the rotating pin 46 have a cross-shaped side view, the rotating pin 46 and the card holder 45 are engaged and connected. Rotating the rotating pin 46 will cause the card holder 45 to rotate, which in turn will cause the rotating shaft 42 to rotate. The rope is passed through the limiting groove 43 into the inside of the rotating shaft 42, which can limit the rope. Then, when the rotating shaft 42 rotates, it will cause the rope to rotate together, which can gradually tighten the rope. Rotating the rotating shaft 42 clockwise or counterclockwise will tighten the rope.

[0033] Reference Figures 2-6 A locking structure 3 is fixed on the outer wall of one side of the support plate 2. The locking structure 3 includes a movable block 31, a connecting shaft 32, a locking block 33 and a limiting block 34. The connecting shaft 32 is fixed on the outer wall of one side of the support plate 2. The movable block 31 is sleeved on the outer side of the connecting shaft 32. The bottom end of the movable block 31 is fixed with a locking block 33. The side view of the locking block 33 and the limiting block 34 is triangular.

[0034] When the rotating shaft 42 rotates clockwise, the shape of the locking block 33 is similar to the shape of the tooth groove on the outer wall of the ratchet disc 41, and it will not affect the rotation of the ratchet disc 41. When the rotating shaft 42 rotates counterclockwise, the teeth on the outer wall of the ratchet disc 41 will enter the groove formed between the locking block 33 and the limiting block 34 and be blocked by the groove. The ratchet disc 41 cannot continue to rotate. At this time, the ratchet disc 41 enters the locked state and cannot rotate counterclockwise. When the ratchet disc 41 needs to rotate counterclockwise, the locking block 33 and the limiting block 34 are rotated above the connecting shaft 32, so that the locking block 33 and the limiting block 34 are away from the ratchet disc 41. At this time, the ratchet disc 41 can rotate counterclockwise.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
