The present invention relates to the field of tensioners in particular to a force adjustable universal displacement tensioner.
The existing tensioner comprises a suction cup assembly and a housing. An external toothed coil spring cover, a coil spring cover and a rope wheel are coaxially disposed in the housing through a coil spring shaft. The external tooth coil spring cover and coil spring cover are both provided in the There is a coil spring, the tension rope sleeve is set on the rope wheel; the two ends of the coil spring shaft are connected to the inner wall of the casing through the bearing; the suction cup assembly and the casing are connected to each other through the universal adjustment assembly; the casing is provided with a force adjustable universal displacement tensioner.
Chinese patent No. 201921438815.2 of A universal displacement tensioner discloses that the universal adjustment assembly includes a rotating U-shaped member, and the top of the buckle is connected to the rotating U-shaped member by T-rivet rotation; the drawback of this structure is that: There are many parts, which is inconvenient to assemble; and the stability is insufficient; the force adjustment component includes a clamping rod that cooperates with the external teeth of the external tooth coil spring cover, and a switch for driving the rotation of the clamping rod, the switch and the clamping rod There is a transmission positioning rod, which is installed in the housing of the tensioner through a fixed sleeve; the transmission positioning rod is provided with a spring, one end of the spring is pressed against the fixed sleeve, and the other end is pressed against the transmission positioning rod Protruding step surface; by controlling the clamping tooth bar to be inserted into the external tooth groove of the external tooth coil spring cover, forming resistance; this structure is complex and easy to damage.
The purpose of the utility model is to provide a force adjustable universal displacement tensioner to solve the problems raised in the background technology.
To achieve above goal, the utility model provides the following technical scheme:
A force adjustable universal displacement tensioner comprising a suction cup assembly and a housing; outer gear spring cover, coil spring covers and a rope puller are arranged in the housing coaxially through a coil spring shaft; coil springs are disposed in both the outer gear spring cover and the coil spring cover; a pulling rope is disposed on the rope puller; one end of the pulling rope which extends out of the housing is connected to a handle; the utility model is characterized in that: the suction cup assembly is connected with the housing through a universal adjusting unit; the suction cup assembly comprises a sucker; a pressing buckle is fixedly disposed on an out side of the sucker; an air cylinder is installed between the sucker and the pressing buckle to suck the out of the sucker; the suction cup assembly also comprises a cardan shaft; one end of the cardan shaft is rotatably connected to the pressing buckle; an other end of the cardan shaft is rotatably connected to bottom of the housing.
Preferably, the cardan shaft comprises a shaft body; a first rotating ball and a second rotating ball are disposed on both ends of the shaft body; the first rotating ball is in rotated and clamped connection in a housing body; the second rotating ball is in rotated and clamped connection in the pressing buckle.
Preferably, the diameter of the first rotating ball is smaller than that of the second rotating ball.
Preferably, a force adjusting component is also included to adjust the pulling force of the pulling rope; the force adjusting component comprises gear clamping rods which are coupled with the outer gear spring cover are rotatably connected with inner walls of the housing and control knobs; control wheels are fixedly disposed on the control knobs; the control wheels which comprise knob fixing components are in clutched connection with the gear clamping rods.
Preferably, the control wheels which comprise knob fixing components are in clutched connection with the gear clamping rods; the knob fixing components comprise connecting shims fixedly connected with the housing; several of connecting grooves are disposed on the connecting shims; connecting rods are disposed on the control knobs; in use, when the control knobs are rotated, each one of the connecting rods are connected to one of the connecting grooves.
Preferably, the control wheel are fixedly connected with the control knobs through a rotating shaft.
Preferably, a group of outer gear spring cover are symmetrically arranged on both sides of the rope puller.
Compared with the prior art, the utility model has the following beneficial effects:
The utility model has the advantages that the application controls the clutch between the clamping rods and the outer gear spring cover, through the control knobs and the control wheels; its structure is more simple; the operation is more convenient, and it is not easy to be damaged; secondly, the cardan shaft is used to connect the housing and the sucker, so the structure is more stable.
In the following, the technical scheme in the embodiment of the utility model will be described clearly and completely in combination with the drawings in the embodiment of the utility model.
