Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an adjustable threaded hole structure. Background Technology

[0002] Rehabilitation medical devices (such as shockwave therapy devices) are generally equipped with a detachable back door and top cover for ease of initial testing and subsequent maintenance (portable devices have a top cover, while desktop devices have both a back door and a top cover). The back door structure is relatively easy to install, as it is located on the back of the device and the appearance requirements are not high. It is generally installed using a snap-on locking method. However, since the top cover structure is exposed on the top of the device, it is generally fixed with countersunk screws on the side for structural strength and aesthetic purposes. However, due to the fit gaps in the installation and the errors caused by the large rounded corners during manufacturing to maintain the product's aesthetics, the mounting holes are misaligned, making it difficult to install the top cover and affecting the product's appearance.

[0003] To address the above issues, achieving adjustable mounting holes is an urgent problem to be solved in the industry. Currently, most solutions to the misalignment problem of mounting holes in rehabilitation medical products use adjustable oblong holes or leaf spring nuts. However, oblong holes or leaf spring nuts have certain drawbacks in use. The oblong holes on the upper part of the housing have a large coverage area and cannot be completely covered by the countersunk screws used for fixing. This not only affects the aesthetics of the product but also does not meet the product safety requirements. Although leaf spring nuts offer some improvement, they require a large installation space and cannot be fully enclosed. Due to the compact and delicate structure of portable devices, they are obviously not suitable. Utility Model Content

[0004] The purpose of this utility model is to overcome the existing technical defects and provide an adjustable threaded hole structure, which solves the problem of difficult installation caused by misalignment of the mounting holes between the upper and lower shell parts of the equipment by adjusting the position of the nut.

[0005] To solve the above-mentioned technical problems, this utility model provides an adjustable threaded hole structure, including a plate-shaped fixing plate. The fixing plate has multiple bent edges bent upwards or downwards around its four edges. A nut placement groove is formed between the fixing plate and each bent edge. A nut that can move along the length and height of the nut placement groove is provided in each nut placement groove. A waist-shaped hole is opened in the middle of the bent edge to expose the threaded hole on the nut. The major and minor axes of the waist-shaped hole are both larger than the diameter of the threaded hole.

[0006] Furthermore, the adjustable threaded hole structure also includes multiple nut limiting members that correspond one-to-one with the bending stop. The fixing plate has an opening that extends vertically through each bending stop at the position corresponding to the inner side of each bending stop. The nut limiting members are inserted vertically through the openings, and a nut placement groove is formed between the nut limiting members and the bending stop.

[0007] Furthermore, the nut limiting member is U-shaped with its opening facing the bent edge, and the width of the U-shaped groove of the nut limiting member is greater than the width of the nut.

[0008] Furthermore, the nut is a flange nut with a flange edge at one end, and a limiting groove for accommodating the flange edge is formed between the upper and lower ends of the nut limiting member and the bent stop edge, and the length of the limiting groove is greater than the outer diameter of the flange edge.

[0009] Furthermore, the upper and lower ends of the nut limiting member are both recessed with grooves to accommodate the flange edge, so that support feet connected to the bent edge are formed on both sides of the groove.

[0010] Furthermore, both sides of the end of the bent retaining edge are recessed with positioning cuts, and the two legs at the upper or lower end of the nut limiting member respectively overlap the two positioning cuts.

[0011] Furthermore, the support leg and the bent edge are fixed together by welding.

[0012] Furthermore, the four edges of the fixing plate are also provided with supporting edges that are bent upwards or downwards, and the supporting edges and the bent blocking edges are oriented in opposite directions.

[0013] Secondly, this utility model provides a shell fixing structure for a rehabilitation medical device. The rehabilitation medical device includes a lower shell and an upper cover that fits onto the upper end of the lower shell. It also includes an adjustable threaded hole structure as described in any of the first aspects. The adjustable threaded hole structure is fixed to the top inner side of the upper cover and located at the upper inner side of the lower shell. The upper end of the lower shell has a countersunk hole for screws to pass through at the middle of each corresponding waist-shaped hole.

[0014] Furthermore, the diameter of the countersunk hole is larger than the diameter of the screw hole.

[0015] This utility model has the following beneficial effects: The adjustable threaded hole structure of this utility model can be applied to the interior of the outer shell of products such as rehabilitation medical equipment. By using the adjustable nut and the oblong hole in the adjustable threaded hole structure, the oblong hole can be designed on the outer shell of the equipment, so that the nut inside can be aligned with the hole on the outer shell of the equipment. This solves the problem of difficult installation caused by misalignment of the mounting holes between the upper and lower parts of the outer shell of the equipment, reduces the installation difficulty, and avoids the problem that the oblong hole on the outer shell of the equipment cannot be completely covered by the countersunk screw, which affects the appearance of the product.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0018] To better understand the technical content of this utility model, the following will further introduce and explain this utility model in conjunction with the accompanying drawings and specific embodiments. It should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of priority, nor do they limit "first" and "second" to be different types.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 like Figures 1 to 7As shown in the figure, the adjustable threaded hole structure 100 of this embodiment includes a plate-shaped fixing plate 1. The fixing plate 1 has multiple bent flanges 11 with its four edges bent upwards or downwards. A nut placement groove 12 is formed between the fixing plate 1 and each bent flange 11. Each nut placement groove 12 is provided with a nut 13 that can move along the length and height of the nut placement groove 12. That is, the position of the nut can be adjusted in the left-right and up-down directions. A waist-shaped hole 14 is opened in the middle of the bent flange 11 to expose the threaded hole 130 on the nut 13. The major and minor axes of the waist-shaped hole 14 are both larger than the diameter of the threaded hole. The waist-shaped hole cooperates with the nut to enlarge the threaded hole when the nut moves. The exposed coverage area allows for easy installation of the screws when this adjustable threaded hole structure is used inside the housing of products such as rehabilitation medical equipment. Simply move the adjusting nut to align the threaded hole on the nut with the countersunk hole on the housing to secure the screw. This eliminates the need for a recessed hole on the housing, solving the installation problem caused by misalignment of mounting holes between the upper and lower housing parts. This reduces installation difficulty and offers a simple structure with low manufacturing cost. Furthermore, by placing the recessed hole structure inside the housing when using the fixing plate, the aesthetics of the product are avoided, as the recessed hole on the housing cannot be completely covered by the countersunk screw.

[0021] In one embodiment, such as Figures 1 to 7 As shown, the adjustable threaded hole structure also includes multiple nut limiting members 2 that correspond one-to-one with the bending stop 11. The fixing plate 1 has an opening 15 that passes through vertically at the position corresponding to the inner side of each bending stop 11. The nut limiting members 2 pass through the opening 15 vertically, and a nut placement groove 12 is formed between the nut limiting members 2 and the bending stop 11.

[0022] Specifically, such as Figures 1 to 7 As shown, the nut limiting member 2 is U-shaped with its opening facing the bending stop 11. That is, the nut limiting member 2 has a U-shaped groove with its opening facing the bending stop 11. This U-shaped groove is used to accommodate the nut 13. The width of the U-shaped groove of the nut limiting member 2 is greater than the width of the two opposite sides of the nut 13, so that the nut 13 can be slightly adjusted up and down after being placed in the U-shaped groove. Of course, in order to realize the movement of the nut in the length direction of the waist-shaped hole, the length of the nut limiting member 2 and the U-shaped groove is greater than the width of the two opposite sides of the nut.

[0023] In one embodiment, such as Figures 1 to 4As shown, nut 13 is a flange nut with a flange edge 131 at one end. Limiting grooves 16 for accommodating the flange edge 131 are formed between the upper and lower ends of the nut limiting member 2 and the bent retaining edge 11, thereby limiting the forward and backward displacement of nut 13 and avoiding the problem of the nut deflecting and causing the screw hole to tilt, making it difficult to install. The length of the limiting groove 16 is greater than the outer diameter of the flange edge 131, that is, nut 13 can move left and right within the length range of the limiting groove, making the structure flexible and reliable.

[0024] In one embodiment, such as Figures 4 to 7 As shown, the upper and lower ends of the nut limiting member 2 are both recessed with grooves 21 to accommodate the flange edge 131, and on both sides of the grooves 21, there are support feet 22 that connect with the bent flange edge 11.

[0025] Specifically, such as Figures 2 to 7 As shown, both sides of the free end of the bending stop 11 are recessed with positioning cutouts 111. The two legs 22 at the upper or lower end of the nut limiting member 2 are respectively attached to the two positioning cutouts 111, and the legs 22 are fixed to the bending stop 11 by welding. The manufacturing process is simple and the cost is low.

[0026] In one embodiment, such as Figures 1 to 7 As shown, the four edges of the fixing plate 1 are also bent upwards or downwards to provide support edges 17. The support edges 17 and the bending stop edges 11 are oriented in opposite directions, that is, the bending directions of the two are one upwards and one downwards, and the support edges 17 are used as the support part of the bending stop edges 11.

[0027] In one embodiment, such as Figures 1 to 5 As shown, the fixing plate 1 is also provided with multiple positioning holes 18.

[0028] In other embodiments, the nut limiting component is made of 1.0mm thick steel plate, which is formed by CNC bending, resulting in high structural strength and high precision.

[0029] In other embodiments, the fixing plate is made of 1.2mm thick steel plate. This material not only has high strength, but also has good corrosion resistance, decorative properties and excellent mechanical properties (good ductility, plasticity and wear resistance).

[0030] Example 2 like Figures 1 to 11As shown in this embodiment, a shell fixing structure for a rehabilitation medical device is provided. The rehabilitation medical device includes a lower shell 101 and an upper cover 102 that covers the upper end of the lower shell 101. It also includes an adjustable threaded hole structure 100 as described in Embodiment 1. A fixing plate 1 is fixed to the inner top of the upper cover 102 by screws 104, so that the fixing plate 1 and the upper cover 102 are connected to form a whole, which is convenient to operate and firmly reliable. After the upper cover 102 and the lower shell 101 are closed, the fixing plate 1 is inserted into the upper inner side of the lower shell 101, and the upper end of the lower shell 101... At the center of each corresponding oblong hole 14, there is a countersunk hole 103 for the screw 104 to pass through. The countersunk hole 103 is a round hole. By sliding and adjusting the position of the nut 13 on the fixing plate 1, the inner and outer nuts 13 and the countersunk hole 103 can be aligned. This solves the problem of difficult installation caused by misalignment of the inner and outer mounting holes in the existing system. The two are then fixed with screws, thereby connecting the upper cover 102 and the lower shell 101. The entire assembly process is relatively simple and does not affect the appearance of the product at all. After connection, the entire countersunk hole is covered by screws, ensuring a beautiful and elegant appearance.

[0031] In the above, the position of the sliding adjusting nut can be adjusted before the top cover is closed, or the position of the nut can be finely adjusted through the countersunk hole and the screw hole.

[0032] In one embodiment, such as Figure 11 As shown, the top inner side of the upper cover 102 is provided with multiple positioning posts 105 that are inserted into the positioning holes 18 one by one, so as to realize the positioning assembly between the fixing plate and the upper cover.

[0033] In a specific embodiment, the diameter of the countersunk hole can be slightly larger than the diameter of the threaded hole. This allows for easy adjustment of the nut's position using external tools (such as screwdrivers) through the countersunk hole, ensuring that the threaded hole on the nut is within the countersunk hole's range.

[0034] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
