Description

Technical Field

[0001] The utility model relates to the technical field of shock wave therapy instrument detection, in particular to a divergent shock wave penetration depth detection tooling. Background Art

[0002] Divergent shock waves mainly generate energy through pneumatic ballistics. The energy focus point is on the skin surface and enters the tissue in a divergent form, acting on the superficial tissue. The detection of the penetration depth of divergent shock waves has been clearly stipulated in the industry standard "YY0950-2015 Pneumatic Ballistic Extracorporeal Shock Wave Therapy Equipment", and relevant practitioners set it by themselves according to this industry standard. Generally, a divergent shock wave generator will be provided with an ergonomic control handle at the end for easy hand-held operation. The shape of this control handle is irregular. Therefore, there is a lack of sufficient restraint between the weight and the control handle; during the penetration depth detection, there will inevitably be a horizontal misalignment between the weight and the control handle, resulting in continuous changes in the contact point between the weight and the control handle, affecting the accuracy of the penetration depth detection. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems and provide a divergent shock wave penetration depth detection tooling.

[0004] The technical solution of the utility model is: a divergent shock wave penetration depth detection tooling, including a detection platform, a piezoelectric sensor, a rubber pad, a bushing, a control handle, a clamping device, and a counterweight; a column is provided behind the detection platform; the divergent shock wave penetration depth detection tooling further includes a counterweight frame; a counterweight is installed on the front top surface of the counterweight frame, and the rear end is slidably matched with the column; a support spoke A extending forward is provided at the bottom of the front end of the counterweight frame; there are two support spokes A, which clamp the end of the control handle; the support spoke A fully restrains the end of the control handle, and can reduce the horizontal misalignment between the control handle and the counterweight during the penetration depth detection, ensuring the accuracy of the penetration depth detection.

[0005] Preferably, the counterweight is a dumbbell plate, which is a counterweight that is relatively easy to equip. At the bottom of the front end of the counterweight frame, there is also a support spoke B extending left and right, which, together with the support spoke A, fully supports the dumbbell plate. Vertical arc-shaped baffles are provided at the outer end of the support spoke A, the outer end of the support spoke B, and the rear end of the counterweight A. The arc-shaped baffles horizontally limit the dumbbell plate, which can prevent the dumbbell plate from detaching from the counterweight frame due to the vibration caused by the control handle. All the arc-shaped baffles are concentric with the dumbbell plate. At the rear end of the counterweight frame, there is a sleeve A sleeved on the column. The divergent shock wave penetration depth detection tooling further includes a locking mechanism. The locking mechanism includes a plum blossom screw. The plum blossom screw cooperates with the side of the sleeve A. The plum blossom screw can act as a fastening screw to lock the height of the counterweight frame, or can cooperate with other structures to lock the height of the counterweight frame. The height of the counterweight frame is not locked when detecting the penetration depth of the divergent shock wave, but when disassembling and assembling the control handle, the position of the counterweight frame can be raised and then locked to facilitate the disassembly and assembly of the control handle.

[0006] Furthermore, a through hole is provided at the axis of the dumbbell plate. A limiting shaft is provided at the front end of the counterweight frame. The limiting shaft is inserted into the through hole to increase the limit of the counterweight frame on the dumbbell plate. The divergent shock wave penetration depth detection tooling further includes a counterweight limiting rod. The front end of the counterweight limiting rod is provided with a clamping shaft extending downward. The clamping shaft is inserted into the through hole. Both the clamping shaft and the limiting shaft fully limit the dumbbell plate, ensuring that the dumbbell plate is restricted within a certain range during the shock wave penetration depth detection, and increasing the accuracy of the penetration depth detection. The rear end of the counterweight limiting rod is provided with a sleeve B sleeved on the column. The locking mechanism cooperates with the side of the sleeve B. The locking mechanism can lock the sleeve B. After installing the control handle, the counterweight limiting rod can be locked to keep the clamping shaft in a state of horizontally limiting the through hole. Also, when disassembling and assembling the control handle, the counterweight limiting rod can be locked at a position farther from the counterweight frame to facilitate the disassembly and assembly of the control handle.

[0007] Preferably, the clamping device is arranged below the counterweight. The clamping device includes a left clamp body, a right clamp body, a hinge shaft, a U-shaped frame, a sleeve C, and a torsion spring. The front end of the left clamp body is provided with a left semi-circular tube matching the middle part of the control handle. The front end of the right clamp body is provided with a right semi-circular tube matching the middle part of the control handle. The left semi-circular tube and the right semi-circular tube cooperate with each other to be able to clamp the middle part of the control handle. The middle parts of the left clamp body and the right clamp body are both hinged to the hinge shaft. The rear ends of the left clamp body and the right clamp body are both provided with deformed operation plates. By controlling the operation plates, the left semi-circular tube and the right semi-circular tube can be opened. The torsion spring is sleeved on the middle part of the hinge shaft. The ends of the torsion spring respectively abut against the inner sides of the operation plates. The torsion spring makes the left semi-circular tube and the right semi-circular tube always tend to be closed to clamp the middle part of the control handle. The U-shaped frame is arranged vertically. The hinge shaft vertically penetrates the open end of the U-shaped frame. The closed end of the U-shaped frame is fixedly connected to the sleeve C. The U-shaped frame connects the left clamp body, the right clamp body and the sleeve C. The sleeve C is sleeved on the column. The locking mechanism cooperates with the side of the sleeve C. The locking mechanism can lock the sleeve C, and the most suitable position of the middle part of the control handle can be selected for clamping.

[0008] Further, the clamping device further includes a limit screw; the limit screw is threadedly connected to the end of the hinge shaft; the tightening end of the limit screw abuts against the side surface of the U-shaped frame; the limit screw axially limits the hinge shaft to prevent the hinge shaft from disconnecting from the U-shaped frame.

[0009] Further, the outer side surface of the operation plate is densely covered with friction ribs to facilitate manual operation to open the left clamp body and the right clamp body.

[0010] Preferably, the divergent shock wave penetration depth detection tooling further includes a ferrule holder; the ferrule is sleeved outside the rubber pad; the ferrule holder includes a horizontal rod and a sleeve D; the ferrule is connected to the sleeve D through the horizontal rod; the sleeve D is sleeved on the column; the locking mechanism cooperates with the side surface of the sleeve D; the locking mechanism can lock the sleeve D and can be adjusted to adapt to the height of the ferrule so that the ferrule is at the connection between the rubber pad and the head end of the control handle.

[0011] Preferably, the divergent shock wave penetration depth detection tooling further includes a pressing plate; the pressing plate is provided with a central hole; the pressing plate is installed on the detection platform through screws; the piezoelectric sensor is embedded in the central hole; the pressing plate horizontally limits the piezoelectric sensor so that the piezoelectric sensor is exactly below the control handle.

[0012] Further, the piezoelectric sensor is a piezoelectric ceramic.

[0013] Preferably, the detection platform includes a bottom frame; the bottom frame includes angle codes and beam bodies; there are four beam bodies, which are connected end to end; the angle codes are arranged at the four corners of the bottom frame and are connected to the inner wall of the beam body; the bottom frame provides a stable bottom for the detection platform.

[0014] Further, the bottom frame further includes end caps; the end caps are buckled on the exposed ends of the beam bodies; the end caps shield the ends of the beam bodies to make the appearance of the bottom frame beautiful.

[0015] Preferably, chamfers are provided on the inner edges of the upper and lower ends of the ferrule to facilitate the entry of the control handle.

[0016] The beneficial effects of the present utility model are as follows: The divergent shock wave penetration depth detection tooling of the present utility model has the following advantages:

[0017] (1) Two support spokes A are arranged below the installation counterweight counterweight frame of the present utility model, which can limit the control handle, enable the counterweight and the control handle to have more constraints, can avoid horizontal misalignment, the contact between the counterweight and the control handle is stable, and ensure the accuracy of the penetration depth detection;
