Example two
The embodiment provides a sensor assembly, referring to fig. 1 and 2, including falling the sensor and realizing the installation mechanism that falls the sensor and install without power failure, fall the sensor and include sensor body 1 and set up the fuse tube fixture 2 in sensor body 1 one side, the inside sensor components and parts that are provided with of sensor body 1, fuse tube fixture 2 is through the mode with the tight complex of fuse tube 3 clamp, installs sensor body 1 and fixes on the fuse tube 3 tubular column.
Unlike the installation mode of adopting manual binding in the prior art, the fall sensor of this technical scheme sets up fuse tube fixture 2 in one side of sensor body 1, through the tight cooperation of clamp of fuse tube fixture 2 and fuse tube 3, realizes fixing sensor body 1 installation on the tubular column of fuse tube 3, simultaneously, this technical scheme still is provided with installation mechanism, carries out the complete set use with the fall sensor.
During installation, the fuse tube clamping mechanism is firstly arranged on one side of the sensor body, the other side of the sensor body is connected to the installation mechanism through the spring clamping assembly, then an operator adjusts the relative angle between the fuse tube clamping mechanism and the fuse tube in advance through the angle adjusting assembly in the installation mechanism, and the operator can install and fix the sensor body on the pipe column side of the fuse tube by conveying the drop sensor to one side of the fuse tube and clamping the fuse tube clamping mechanism and the fuse tube through the handheld rod in the installation mechanism. According to the technical scheme, the fuse tube clamping mechanism is arranged on the drop sensor, the sensor body is clamped and mounted on the fuse tube, and the fuse tube clamping mechanism is matched with the mounting mechanism, so that the sensor body can be mounted under the condition of no power failure, power failure treatment on a power system of the whole area is not required, meanwhile, an operator can adjust the mounting angle in advance according to the field working condition through the mounting mechanism, and the convenient mounting can be realized directly at the ground, and on the premise of ensuring the safety of the operator, the normal power consumption requirement of a user in the local area is guaranteed, and the mounting efficiency is improved.
When the device is further used, an operator can adjust the relative angle between the fuse tube clamping mechanism and the fuse tube in advance through the angle adjusting assembly in the mounting mechanism, specifically, the angle adjusting assembly (the adjustable damping hinge) can not be locked firstly, the drop sensor is sent to one side of the fuse tube through the handheld rod, after the fuse tube clamping mechanism is aligned with the fuse tube in parallel, the drop sensor is retracted, the angle position of the fuse tube clamping mechanism is kept unchanged, and the device is mounted after the adjustable damping hinge is locked.
In a specific embodiment, regarding the adjustable damping hinge, as a person skilled in the art, in order to achieve the purpose of uninterrupted installation, the installation state of the fuse tube in space is certain (the state that the relevant moving contact and the static contact keep matched), and one of the basic problems that can be solved by adopting the adjustable damping hinge as an angle adjusting component is as follows: the angle between the two hinges on the adjustable damping hinge is changed, so that the angle of the spring clamping assembly relative to the handheld rod is adjustable, and the spring clamping assembly is suitable for the specific position where an operator stands, the lifting height of the installation mechanism and the like in each operation scene; another problem that can be solved is: the change of the included angle between the two hinges occurs under the damping effect, and the damping size is adjustable, so that the moment required for changing the relative angle is larger when the damping is adjusted to be larger, and the moment required for changing the relative angle is smaller when the damping is adjusted to be smaller. In the above case, the fall sensor mounting may be accomplished in the following manner: when an operator selects an operation position, the fall sensor is mounted on the mounting mechanism according to the height and operation habit of the operator, the mounting mechanism is lifted, the fuse tube clamping mechanism at the front side of the fall sensor is propped against the fuse tube, the two hinges on the adjustable damping hinge are forced to rotate relatively through contact force (overcoming relative rotation resistance generated by damping), when the strip-shaped opening of the fuse tube clamping mechanism is parallel to the fuse tube (the process can be understood to enable the state of the locking angle adjusting assembly to be self-adaptive according to specific operation requirements), the mounting mechanism is put down, the resistance of the relative rotation is increased in a mode of increasing the damping through the adjusting angle adjusting assembly (the process can be understood to be the state of the locking angle adjusting assembly), and then the mounting mechanism is lifted again, so that the fall sensor can be stably and efficiently mounted on the fuse tube due to the fact that the angle adjusting assembly is not easy to deform.
In a specific embodiment, the adjustable damping hinge comprises two hinges hinged with each other through a hinge shaft, and the damping adjustment is realized by increasing the friction force of the two hinges relative to each other, specifically: in the axis direction of the hinge shaft, the hinge cylinder of one hinge is sleeved on the front side of the hinge shaft, the hinge cylinder of the other hinge is sleeved on the rear side of the hinge shaft, the rear end of the hinge cylinder at the front side is in direct contact with the front end of the hinge cylinder at the rear side or acts on the hinge cylinder through an elastic friction plate, and when damping adjustment is carried out, the distance between the front end of the hinge cylinder at the front side and the rear end of the hinge cylinder at the rear side is changed by tightening or loosening the hinge shaft, so that the aim of changing the moment required by the relative rotation of the hinge is fulfilled. A preferred application is to provide an elastic friction plate so that the distance can be adjusted over a large range (distance magnitude has a linear relationship with damping magnitude) to obtain the proper damping magnitude required for the adaptation process.

The plastic-based high-efficiency cleaning and packaging device is generally applied to connection and packaging of materials such as plastics, synthetic fibers and metals, and has the characteristics of high efficiency, rapidness, cleanliness and accuracy.
The following is the basic principle of ultrasonic welding:
ultrasonic welding utilizes high-frequency frictional heat generated by sonic vibration. During welding, two materials (typically plastic pieces) being joined are placed together, one portion being transferred to the other by ultrasonic vibration, creating frictional heat. The frictional heat causes localized melting of the contact surfaces, and then upon cessation of vibration, the melted region rapidly cools and solidifies, forming a strong bond.
