Technical Field

[0001] The utility model belongs to the technical field of fixing a Christmas tree stand, and in particular relates to a tensioning device for a Christmas tree stand. Background Art

[0002] A Christmas tree is an evergreen tree decorated with candles and ornaments. As one of the important elements of Christmas, the modern Christmas tree originated in Germany and gradually became popular around the world, becoming one of the most famous traditions in Christmas celebrations. The Christmas tree is installed through a Christmas tree stand, and the Christmas tree stand needs to be used with related installation components to be firmly fixed to the ground.

[0003] Some structures on the market are mainly composed of a seat tube, a base plate, a steel wire, a ratchet and a ratchet shaft and other similar parts. Its main feature is that it has a number of jaws installed in a jaw bracket that is placed obliquely at a certain angle to the base plate. After the steel wire passes through the holes on the jaws in turn, both ends of the steel wire are connected to the ratchet shaft with a ratchet. During operation, the ratchet is driven by the handle to gradually tighten the steel wire, and the jaws worn on the steel wire move from bottom to top along the inclination of the jaw bracket to clamp the Christmas tree.

[0004] The steel wire of the utility model will not be exposed outside the shell, and can be stored in the packaging box when the Christmas tree base is not in working state. However, some products still have the problem that it is easy to get stuck during the tightening process, and when the pedal rod is used with too much force, the check piece connected to the gear will be deformed due to excessive force, resulting in structural damage. For this reason, we propose a tightening device for a Christmas tree stand. Utility Model Content

[0008] Preferably, the interior of the installation frame is hingedly connected to a Christmas tree fixing claw via a movable shaft, and the outer side walls of the Christmas tree fixing claw are penetrated by a first connection opening for a steel wire rope.

[0009] Preferably, the first connecting ports of the steel wire rope are connected with a steel wire rope, and both ends of the steel wire rope pass through the steel wire rope perforating member and are connected to the steel wire rope reel.

[0010] Preferably, the outer side wall of the thorn gear is meshingly connected with a lever pawl, and one end of the lever pawl is connected to a lever stop spring.

[0011] Preferably, the other end of the lever stop spring is connected to a sliding lock, and the sliding lock is movably connected inside a movable groove, and the movable groove is provided on an outer side wall of the tension rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The corresponding extension is provided on the inner side of the mounting hole of the connecting metal part shaft for installing and fixing the tension rod. In the case of not installing the wire rope take-up shaft, the connecting metal part and the tension rod can rotate freely without causing squeezing pressure on the wire rope take-up shaft. When all the tightening devices are assembled, the tension rod is swung once by the lever catch each time the tension rod is stepped on, and the thorn gear is curled in the tightening direction. The wire rope is tightened through the groove of the wire rope take-up shaft. The extension on the inner side of the connecting metal part shaft minimizes the shear force of the wire rope take-up shaft, expands the curling force of the wire rope take-up shaft, prevents the connecting metal part, the wire rope take-up shaft, the thorn gear and the tension rod from getting stuck, and further improves the smoothness of the wire rope retraction and release. The connection mode between the pedal rod and the base is changed to multi-faceted contact, and the surface and the shaft are in contact with force, so it will not get stuck, and when the pedal rod is subjected to 150 kg pressure test, the force point is at the contact surface of the base and the shaft, the check plate is subjected to very little force and will not be deformed or damaged. The tensioning handle has a simple structure and low cost, which improves the stability and practicality of the device and solves the problem that it is easy to get stuck during the tensioning process and the check plate connected to the gear will be deformed due to excessive force when the pedal is used with too much force, resulting in structural damage. In addition, the water outlet, water inlet, L-shaped groove and water outlet plug increase the water outlet, the water outlet and the water outlet plug are interlocked, and the water inlet and the water inlet plug are interlocked. When drainage is required, the overall structure can be tilted to the water outlet, and then the water outlet plug can be opened to pour out the water inside. The outer side of the water outlet is connected to the upper welding part of the fixed base, and the water outlet is located at and contacts with the welding position. The main purpose is to facilitate the outflow of water and avoid the existence of water left inside.

[0015] By setting the Christmas tree fixing claw, the Christmas tree fixing claw can be used to fix Christmas tree stands of different sizes during use. Afterwards, during the activity of the thorn gear, the gear teeth and the gear spring can play a good limiting role on the thorn gear during the winding process, making the thorn gear more stable. Then, the sliding lock buckle can be used to adjust the lever catch during use. When the wire rope is wound, the thorn gear can be limited by the lever catch to make the use of the thorn gear more stable. When unwinding is required, the lever catch can be moved to allow the thorn gear to be unwound. In this way, a tensioning device for a Christmas tree stand is completed.
