Description

Technical Field

[0001] The utility model relates to the technical field of tensioners, in particular to a tensioner structure. Background Art

[0002] The tensioner is used to fix the goods during transportation, movement, shipment or storage. After being locked, they will not fall off, are safe and reliable, light, easy to operate, and protect objects from damage. It is a device for reinforcing steel formwork and compressing wooden boards, and mainly plays a tensioning role. The existing tensioner includes a tensioning sleeve, a screw rod, and a tensioning ring. The two screw rods are connected by a connecting rod, and an iron rod passes through the radial direction of the connecting rod. When two objects need to be tightened, the tensioning ring can be moved to the middle at the same time by rotating the iron rod, thereby achieving the tightening of the objects. However, the two tightened objects often need to be carried with the tensioner during transportation and storage, and the iron rod on the tensioner occupies a large space, which requires high material and storage space. CN117444887A discloses a tensioner with a quickly adjustable pull rod. After the threaded connection between the arc block and the threaded pull rod is released, the threaded pull rod slides freely along the second connecting block, thereby quickly adjusting the extended length of the threaded pull rod. However, the rotating rod in the present invention is not convenient to disassemble, which causes inconvenience in the required transportation and storage. Utility Model Content

DETAILED DESCRIPTION

[0015] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0016] according to Figure 1-2 As shown, a tensioner structure includes two tensioning sleeves 1, and the two tensioning sleeves 1 are cooperatively connected with tensioning screws 2. The two tensioning screws 2 are connected by a connecting part 3. The connecting part 3 is provided with a screwing assembly for driving the connecting part 3 to rotate. The screwing assembly includes a gear 4 sleeved on the connecting part 3, and a locking block 5 cooperatively connected with the gear 4. The locking block 5 is connected with an adjusting screw 11, and the adjusting screw 11 is cooperatively connected with a rotating frame 6.

[0017] In the above specific embodiment, the connecting part 3 can be rotated by rotating the screwing assembly, thereby driving the tensioning screw 2 to rotate, so that the two tensioning sleeves 1 move toward the middle at the same time, thereby realizing the tensioning of the object. In the utility model, by screwing the adjusting screw 11, the locking block 5 is locked with the gear 4, and the rotating frame 6 is tightly connected with the connecting part 3, so that the tensioning between the two objects is realized by rotating the rotating frame 6. After the object is tightened, during the transportation and warehousing process, the locking block 5 is moved away from the gear 4 by screwing the adjusting screw 11 in the direction, and the locking relationship between the locking block 5 and the gear 4 is released, so that it is easy to remove the rotating frame 6 from the connecting part 3, thereby reducing the space occupied during the transportation and storage of the object.

[0018] The locking block 5 is an arc-shaped structure, and a tooth groove meshing with the gear 4 is provided on a side of the locking block 5 close to the gear 4 .

[0019] The rotating frame 6 includes hooks 61 located on both sides of the gear 4 and connected to the connecting part 3. The two hooks 61 are connected by a crossbeam 62. The adjusting screw 11 is threadedly connected to the crossbeam 62. By setting the hooks 61, effective support can be provided during the locking process of the locking block 5 and the gear 4. At the same time, the hooks 61 are tightly connected to the connecting part 3, which can reduce the pressure on the gear 4 during the rotation of the rotating frame 6.

[0020] An adjustment handle 7 is provided at one end of the adjustment screw 11 away from the locking block 5, and a rotating handle 8 is provided on the cross beam 62. Anti-slip sleeves 9 are provided on both the adjustment handle 7 and the rotating handle 8. The adjustment screw 11 is easy to screw and the rotating frame 6 is easy to rotate. Preferably, two rotating handles 8 are provided to facilitate the staff to apply force evenly and to use both hands to screw the rotating frame 6 at the same time.

[0021] An anti-slip layer 63 is provided at the contact point between the hook claw 61 and the connecting portion 3 , thereby increasing the tightness of the connection between the hook claw 61 and the connecting portion 3 .

[0022] Guide rods 10 are provided on both sides of the locking block 5, and the guide rods 10 are slidably connected to the hook claws 61. The locking block 5 is rotatably connected to the adjusting screw 11 to ensure that during the rotation of the adjusting screw 11, the locking block 5 performs linear motion without rotating.
