Problems solved by technology

[0004] In view of the above prior art, disassembly and assembly personnel use pliers to lock the casing of the matching water resistor to fasten or disassemble the water resistor. This locking method has several disadvantages: one is easy to scratch the surface of the casing of the water resistor; It is not easy to lock, and the pliers are easy to slip, resulting in loose packaging or difficult to disassemble; third, when the pliers slip, it is easy to cause damage to the hands of dismantlers, and this locking method has certain safety hazards for dismantlers. , the invention provides a water resistance fixture

Embodiment 1

[0025] Such as figure 1 As shown, a water resistance clamp includes two hoop-shaped parts, and the hoop-shaped part includes a hoop body and two connecting lugs. The two connecting lugs are respectively fixed on different sides of the hoop body, and the connecting lugs Both are provided with bolt holes, and also include connecting bolts that pass through the bolt holes. The two hoop-shaped parts form a bolt connection relationship through the connecting bolts, and both sides of the hoop body are provided with connecting bolts. A clamping gap for water resistance clamping is formed between them;

[0026]Each connecting lug is connected with a turning handle, one end of each turning handle is connected with the corresponding connecting lug, the distance between the other end of each turning handle and the clamping gap is linearly adjustable, and the hoop body can be driven around the water through the turning handle The axis of the resistor rotates.

[0027] Specifically, in t...

Embodiment 2

[0030] Such as figure 1 As shown, this embodiment is further limited on the basis of Embodiment 1: as a form that can be used to open the handle, when the torque is applied to the water resistance, the length of the moment arm when the torque is applied is increased, and at the same time it is convenient The technical scheme that makes the turning handle in the storage state, the connecting lugs are provided with hinged shafts, one end of each turning handle is hingedly connected to the corresponding connecting lugs through the corresponding hinged shaft, and the axis of each hinged shaft is connected to the water resistance axis vertical. Specifically, in the above solution, the switch between the storage state and the unfolded state of the rotation handle is realized by rotating the rotation handle around the hinge axis. Furthermore, in order to optimize the force on the hinge shaft when torque is applied to the water resistance, it can be set so that the axis of the hinge ...

Embodiment 3

[0036] This embodiment is further limited on the basis of any one of the technical solutions provided by any one of the above embodiments: in order to allow the operator to loosen and tighten the connecting bolts only by hand-tightening, so as to facilitate the operation of the fixture, The connecting bolts are butterfly bolts.

[0037] In order to match the shape of the water resistance, a cylindrical clamping gap is obtained between the two hoops to increase the contact area between the fixture and the water resistance. Both hoops are in the shape of arc plates.

[0038] In order to facilitate the structural strength of the clamp, each hoop-shaped part is provided with a reinforcing rib, and the reinforcing rib is used to strengthen the connection strength between the hoop body and the upper connecting lug.

Abstract

The invention discloses a water resistor clamp. The water resistor clamp comprises two hoop-shaped parts. Each hoop-shaped part comprises a hoop body and two connecting lugs, wherein the two connecting lugs are fixed to different sides of the hoop body respectively, and bolt holes are formed in the connecting lugs respectively. Each hoop-shaped part further comprises a connecting bolt penetrating through the bolt holes. The two hoop-shaped parts are in bolt connection through the connecting bolts. Connecting bolts are arranged on the two sides of each hoop body respectively, and a clamping gap used for clamping a water resistor is formed between the two hoop bodies. A rotary handle is arranged on each connecting lug, one end of each rotary handle is connected with the corresponding connecting lug, the distance between the other end of each rotary handle and the clamping gap is linearly adjustable, and the hoop bodies can be driven through the rotary handles to rotate around the axis of the water resistor. The water resistor clamping performance of the clamp is stable, and sufficient torque can be applied to the water resistor through the clamp conveniently in a narrow water resistor installation space.

Description

technical field [0001] The invention relates to the technical field of tools for fixing and matching water resistors, in particular to a water resistor clamp. Background technique [0002] In the acceleration cavity of the linear induction accelerator, it is necessary to use a water resistor with a large resistance heat capacity to match the impedance of the drive circuit. The shell of the water resistor is a plexiglass cylindrical shell, and a conductive solution such as copper sulfate or potassium chloride is filled into the shell, and the two ends of the shell are sealed by copper conductor electrodes. and reach. Because the water resistance heats up through the current, it is easy to leak air bubbles, and sometimes water leakage will cause air bubbles due to poor sealing. When operating at high voltage, air bubbles are the weak link of insulation, and electrical breakdown is easy to occur. In addition, the water resistance increases with time, and its resistance value ...
