[0039] The utility model provides a transducer handle protective cover.

[0040] See also Figures 1 to 4 , Figure 1 This is a structural diagram of an embodiment of a transducer handle protective cover provided by the utility model. Figure 2 This is a cross-sectional view of an embodiment of an ultrasonic transducer handle assembly provided by the present invention. Figure 3 for Figure 2 A partial enlarged view of point A in the middle. Figure 4 This is an exploded view of an embodiment of an ultrasonic transducer handle assembly provided by the present invention.

[0041] In one embodiment of the present utility model, the transducer handle protective cover 100 is sleeved on the front end of the transducer handle 200. The transducer handle includes a shell 210 and a variable amplitude rod 230 arranged in the shell. The protective cover 100 includes a first sleeve 110 and a second sleeve 120 nested in the first sleeve 110; wherein, the first sleeve 110 has a first support portion 101, the first sleeve 110 is sleeved on the front end of the shell 210 and the end face of the first support portion 101 abuts against the front end face of the shell 210; the second sleeve 120 is sleeved on the variable amplitude rod 230.

[0042] The transducer handle protective cover 100 in the technical solution of the present invention is arranged on the front end of the transducer handle 200. Since the end face of the first support part 101 of the protective cover 100 abuts against the front end face of the shell, and the second cover body is arranged on the amplitude transformer, when the transducer handle 200 is collided or falls, the first support part 101 and the second cover body 120 can provide support for the transducer handle 200, avoiding direct collision of the transducer handle 200 with an impactor or the ground, thereby improving the protective effect of the protective cover 100 on the transducer handle 200 and reducing the possibility of the transducer handle 200 being damaged by falling.

[0043] In one embodiment, the transducer handle further includes an electrode ring 220 sleeved on the front end of the housing. The first housing 110 further includes a second support portion 102 coaxial with the first support portion. The diameter of the second support portion 102 is smaller than that of the first support portion 101, and the end surface of the second support portion abuts the end surface of the electrode ring 220. Because the diameter of the first support portion 101 is larger than that of the second support portion 102, the two support portions of different diameters correspond to the outer shape of the transducer handle 200 and can support different parts of the transducer handle 200, thereby absorbing impact forces on the corresponding parts and further reducing the possibility of damage to the transducer handle 200 from falling.

[0044] Reference Figures 1 to 4 In an embodiment of the present utility model, the second sleeve has a second accommodating cavity for accommodating the front end of the transducer handle, and the second sleeve has a third support portion 103. When the protective cover 100 falls and deforms, on the basis of the first support portion 101 and the second support portion 102 supporting the transducer handle 200, the third support portion 103 can further provide support for the transducer handle. By supporting the transducer handle 200 through three support portions, the possibility of the transducer handle 200 directly colliding with the ground is further reduced, thereby reducing the possibility of damage to the transducer handle 200.

[0045] In one embodiment, in a natural state (i.e., when the protective cover is not impacted or the transducer is not dropped), a distance may be present between the protective cover and the front end of the transducer handle (i.e., the end face of the first support portion is spaced apart from the front end face of the housing, the second support portion is spaced apart from the end face of the electrode ring of the transducer handle, and the third support portion is spaced apart from the end face of the horn). Specifically, in a natural state, the distance between the first support portion 101 and the front end of the transducer handle 200 is smaller than the distance between the second support portion 102 and the front end of the transducer handle 200, and the distance between the second support portion 102 and the front end of the transducer handle 200 is smaller than the distance between the third support portion 103 and the front end of the transducer handle 200. Since the three support portions have different distances from the front end of the transducer handle 200, when the protective cover 100 is deformed, the first support portion 101, the second support portion 102, and the third support portion 103 will sequentially contact the front end of the transducer handle 200. When the protective cover 100 is slightly deformed due to falling, the distance between the first support part 101 and the front end of the transducer handle 200 is small, and only the first support part 101 is in contact with the front end of the transducer handle 200, forming a first-level support; when the protective cover 100 is slightly deformed due to falling, the first support part 101 and the second support part 102 are both in contact with the front end of the transducer handle 200, forming a second-level support; when the protective cover 100 is greatly deformed due to falling, the first support part 101, the second support part 102 and the third support part 103 are all in contact with the front end of the transducer handle 200, forming a third-level support. Through the above-mentioned three-level support, when the transducer handle 200 falls at different heights and causes the protective cover 100 to deform to different degrees, the protective cover 100 can support the transducer handle 200 through the corresponding first-level support, second-level support, or third-level support, thereby preventing the transducer handle 200 from directly colliding with the ground, enabling the protective cover 100 to provide better protection and reducing the possibility of the transducer handle 200 being damaged by falling.

[0046] In one embodiment, at least one of the end surface of the first support portion 101 facing the transducer handle 200 , the end surface of the second support portion 102 facing the transducer handle 200 , and the end surface of the third support portion 103 facing the transducer handle 200 is perpendicular to the axis of the transducer handle 200 .

[0047] In an embodiment of the present invention, the front end of the transducer handle 200 is provided with an electrode ring 220, an amplitude-changing structure of an amplitude-changing rod 230, etc., and is relatively heavy. In addition, a cable is connected to the rear end of the handle, so that when the transducer handle 200 falls, the front end of the transducer handle 200 often falls vertically toward the ground. In this embodiment, at least one of the end surface of the first support portion 101 facing the transducer handle 200, the end surface of the second support portion 102 facing the transducer handle 200, and the end surface of the third support portion 103 facing the transducer handle 200 is perpendicular to the axis of the transducer handle 200, so that the three support portions can provide more support force in the vertical direction, thereby more effectively protecting the transducer handle 200 from vertical falls. Specifically, in this embodiment, the first support portion 101, the second support portion 102, and the third support portion 103 are arranged in sequence along the direction away from the transducer handle 200, which is more conducive to achieving layered support through the deformation of the protective cover 100, thereby improving the protective effect of the protective cover 100.

[0048] In one embodiment, the first sleeve 110 has a first accommodating cavity 111, and the front end of the transducer handle 200 is accommodated in the first accommodating cavity 111. The first support portion 101 is the end of the first sleeve 110 facing the transducer handle 200, and the second support portion 102 extends circumferentially toward the center along the inner wall of the first accommodating cavity 111.

[0049] Reference Figures 1 to 4 In an embodiment of the present invention, the protective cover 100 includes a first cover body 110. The first cover body 110 is mounted on the exterior of the housing 210 of the transducer handle 200, securing the protective cover 100 to the housing 210 and protecting the housing 210 and the electrode ring 220 of the transducer handle 200. Furthermore, by having the first cover body 110 mounted on the exterior of the front end of the transducer handle 200, the protective cover 100 and the transducer handle 200 are securely connected, preventing the transducer handle 200 from shaking within the protective cover 100. This reduces the impact on the transducer handle 200 when it is dropped, thereby reducing the possibility of damage to the transducer handle 200.

[0050] In one embodiment, the second sleeve 120 is located inside the first accommodating cavity 111 , and the second sleeve 120 has a second accommodating cavity 121 for accommodating the front end of the transducer handle 200 . The third support portion 103 is the end of the second sleeve 120 facing the transducer handle 200 .

[0051] Reference Figures 1 to 4In an embodiment of the present invention, the protective cover 100 includes a second cover 120, which is sleeved on the outside of the horn 230 of the transducer handle 200 to protect the horn 230. Furthermore, the first cover 110 and the second cover 120 form a double-layer sleeve that is sleeved on the front end of the transducer handle 200. This ensures a secure connection between the protective cover 100 and the transducer handle 200, and prevents the transducer handle 200 from shaking within the protective cover 100. This reduces the impact on the transducer handle 200 when it falls, thereby reducing the possibility of damage to the transducer handle 200.

[0052] Specifically, the first support portion 101 is used to abut against the first abutment portion 211 on the shell 210. In the event of a fall or collision, the protective cover 100 first supports the shell 210 of the transducer handle 200. The shell 210 is hard and protects the transducer handle 200. The protective cover 100 supports the shell 210 to provide better protection. The second support portion 102 is used to abut against the second abutment portion 221 on the electrode ring 220. The electrode ring 220 is made of conductive metal and is not easily damaged. The protective cover 100 supports the electrode ring 220 to provide better protection. The third support portion 103 is used to abut against the third abutment portion 231 on the horn 230. The horn 230 is also made of metal and is not easily damaged. The protective cover 100 supports the horn 230 to provide better protection.

[0053] In one embodiment, the second housing 120 is integrally connected to the first housing 110 , and a reinforcing rib 130 is provided between the outer wall of the second housing 120 and the inner wall of the first accommodating cavity 111 .

[0054] Reference Figure 6 and Figure 7 In an embodiment of the present invention, the protective cover 100 further includes reinforcing ribs 130. The reinforcing ribs 130 connect the first cover body 110 and the second cover body 120, thereby enhancing the overall structural strength of the protective cover 100 and improving the protective cover 100's ability to resist impact, thereby enhancing the protective effect of the protective cover 100 on the transducer handle 200. Specifically, in this embodiment, a plurality of reinforcing ribs 130 are evenly spaced along the outer circumferential wall of the second cover body 120 to improve the uniformity of the circumferential strength of the protective cover 100, ensure the strength of the protective cover 100, and extend the service life of the protective cover 100.

[0055] In one embodiment, the protective cover 100 further includes a support structure 140 , which is fixed to the inner wall of the first accommodating cavity 111 , and one end of the support structure 140 facing the electrode ring 220 is flush with the second support portion 102 ; and / or,

[0056] The first housing 110 and / or the second housing 120 are made of hard insulating plastic.

[0057] Reference Figure 6 In an embodiment of the present invention, the protective cover 100 further includes a support structure 140. One end of the support structure 140 facing the electrode ring 220 is flush with the second support portion 102, thereby increasing the area of the second support portion 102 and the supporting effect of the second support portion 102 on the electrode ring 220, thereby enhancing the protective effect of the protective cover 100 on the transducer handle 200.

[0058] In an embodiment of the present invention, the first sleeve 110 can be made of a hard insulating plastic material, such as polypropylene, polyethylene, etc., and the second sleeve 120 can also be made of a hard insulating plastic. Hard plastic has high mechanical strength and can protect the transducer handle 200 from damage caused by collisions and falls. On the other hand, insulating plastic can reduce the risk of electrical leakage, ensure that the electrode ring 220 of the transducer handle 200 is isolated from the circuit, and reduce short circuit problems. On the other hand, plastic has good corrosion resistance, wear resistance and scratch resistance, is suitable for use in medical environments, and extends the service life of the protective cover 100. On the other hand, plastic materials are easy to process, convenient for manufacturing complex shapes, and have low manufacturing costs.

[0059] In one embodiment, the second housing 120 further defines a third accommodating cavity 122 . The third accommodating cavity 122 is at least partially located within the second accommodating cavity 121 , and an inner diameter of the third accommodating cavity 122 is smaller than an inner diameter of the second accommodating cavity 121 .

[0060] Reference Figure 1 and Figure 2 In an embodiment of the present invention, the second housing 120 further includes a third accommodating cavity 122 for accommodating the connecting screw 240 of the transducer handle 200. Specifically, a gap is formed between the inner wall of the third accommodating cavity 122 and the connecting screw 240, thereby reducing the possibility of the connecting screw 240 colliding with the inner wall of the third accommodating cavity 122 when dropped, thereby reducing the possibility of damage to the connecting screw 240.

[0061] In one embodiment, a buffer 150 is provided at the end of the third accommodating cavity 122 away from the second accommodating cavity 121 , and the buffer 150 is a soft insulating buffer 150 .

[0062] Reference Figure 8 and Figure 9In an embodiment of the present invention, the buffer 150 is made of a soft insulating plastic, such as rubber, polyurethane, etc., which has good elasticity and cushioning properties, can absorb and disperse the impact force during a collision, and prevent the connecting screw 240 from directly contacting the inner wall of the protective cover 100, thereby better protecting the connecting screw 240 and reducing the possibility of damage to the connecting screw 240 caused by falling or collision. Specifically in this embodiment, the end of the third accommodating cavity 122 away from the second accommodating cavity 121 has a larger volume, and the end close to the second accommodating cavity 121 has a smaller volume. The shape of the buffer 150 corresponds to the shape of the end of the third accommodating cavity 122 away from the second accommodating cavity 121. After the buffer 150 is installed in the third accommodating cavity 122 due to its own deformation ability, the buffer 150 is difficult to detach, thereby preventing the buffer 150 from falling off and being lost. The buffer member 150 is provided with a groove at one end facing the connecting screw 240. When the protective cover 100 is put on the transducer handle 200, the end of the connecting screw 240 away from the amplitude transformer 230 is inserted into the groove, so that this end of the connecting screw 240 is protected by the buffer member 150 in all directions, thereby reducing the possibility of damage from falling.

[0063] In one embodiment, a buffer portion is provided at one end of the first sleeve 110 away from the transducer handle 200, and the buffer portion includes a buffer protrusion 112 and / or a buffer recess 113; wherein,

[0064] The buffer protrusion 112 protrudes in a direction away from the transducer handle 200 , and the buffer recess 113 is recessed in a direction approaching the transducer handle 200 .

[0065] Reference Figure 8 and Figure 9 In an embodiment of the present invention, a buffer protrusion 112 is provided at one end of the first sleeve 110 away from the transducer handle 200. The buffer protrusion 112 protrudes in a direction away from the transducer handle 200, so that this end of the protective sleeve 100 can produce a greater deformation during a collision, changing a rigid collision into a flexible collision, thereby making the protective sleeve 100 have a better energy absorption effect, further reducing the possibility of damage to the transducer handle 200 when it falls vertically.

[0066] Reference Figure 8 and Figure 9 In an embodiment of the present invention, a buffer recess 113 is provided at one end of the first sleeve 110 away from the transducer handle 200, so that this end of the protective sleeve 100 is more likely to deform during a collision, thereby making the protective sleeve 100 have a better energy absorption effect, further reducing the possibility of damage to the transducer handle 200 when it falls vertically.

[0067] In one embodiment, the inner wall of the first support portion 101 is provided with a detachable structure 160 , and the protective cover 100 is detachably connected to the transducer handle 200 via the detachable structure 160 ; and / or,

[0068] An anti-slip structure 170 is provided on the outer wall of the protective cover 100 .

[0069] Reference Figures 1 to 3 In an embodiment of the present invention, the first housing 110 and the housing 210 are connected by a detachable structure 160, so that the protective cover 100 and the housing 210 are easy to assemble and disassemble. When the protective cover 100 is placed outside the housing 210, the protective cover 100 is prevented from being separated from the transducer handle 200; when the transducer handle 200 needs to be used, it is easy to detach. The detachable structure 160 can be implemented in a variety of ways such as screw connection or snap connection. Specifically, in this embodiment, a snap-fit groove 161 is provided on the inner wall of the first accommodating cavity 111, and a corresponding snap-fit protrusion is provided on the outer wall of the housing 210. When the protective cover 100 is placed outside the housing 210, the snap-fit protrusion is inserted into the snap-fit groove 161 to achieve a detachable connection, which is convenient to operate and easy to process.

[0070] In an embodiment of the present invention, an anti-slip structure 170 is provided on the outer wall of the protective cover 100 to increase the friction between the user's hand and the protective cover 100, making it easier to disassemble and assemble the protective cover 100. The anti-slip structure 170 can be in the form of anti-slip protrusions, such as Figure 9 The anti-slip structure 170 may take the form of an anti-slip groove, for example Figure 1 shown.

[0071] Reference Figure 4 and Figure 5 The present invention also provides an ultrasonic transducer handle assembly, comprising:

[0072] The transducer handle 200 includes a housing 210 and a horn 230 disposed in the housing 210; and

[0073] The transducer handle protective cover 100 is placed on the front end of the shell 210 , the end surface of the first support portion 101 abuts against the front end surface of the shell 210 , and the second cover 120 is placed on the horn 230 .

[0074] The specific structure of the transducer handle protective cover 100 is similar to that of the aforementioned embodiments. Since this ultrasonic transducer handle assembly utilizes all of the technical solutions of all of the aforementioned embodiments, it at least possesses all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be detailed here. Specifically, the use of the aforementioned protective cover 100 reduces the likelihood of damage to the transducer handle 200 from falling, thereby extending the service life of the transducer handle 200 and ensuring its normal operating performance.

[0075] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
