Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically to an adjustable auxiliary fastening device for lead aprons. Background Technology

[0002] Lead aprons are crucial protective equipment in medical procedures such as radiological diagnosis and treatment, and their fit and airtightness directly affect the health and safety of the wearer. Currently, lead aprons are commonly closed using Velcro (hook and loop fasteners). Velcro has the advantages of being easy to use and inexpensive.

[0003] However, hook and loop fasteners suffer from significant functional degradation during use. Their main drawbacks are: 1) Repeated adhesion causes wear on the hook surface. Lead aprons require frequent putting on and taking off; as the hook and loop surfaces repeatedly adhere and separate, the hooks gradually fatigue, break, or even fall off, resulting in a significant decrease in adhesive strength; 2) Contamination: Fibers, dust, and other contaminants in the medical environment easily adhere to the hook and loop surfaces, forming a protective layer that severely weakens the adhesive effect; 3) After the hook and loop fasteners deteriorate or fail, replacing them by sewing or other methods can easily cause cracks and damage to the lead apron, compromising the overall airtightness of the protection and allowing radiation to leak through the damaged areas, endangering the wearer's health.

[0004] Therefore, there is an urgent need for an auxiliary fastening device that can be directly adapted to the existing Velcro installation position without damaging the lead apron body and strap structure. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects in the prior art where the adhesive strength of the lead apron hook and loop fasteners weakens due to repeated use, making it impossible to repair without damage, thus affecting the protective effect and service life of the lead apron. In this way, an adjustable auxiliary fastening device for lead aprons is provided that does not require perforation, can be installed without damage at the original position of the lead apron hook and loop fasteners, has a reliable connection, and can be reused.

[0006] Therefore, this utility model provides an adjustable auxiliary fastening device for lead aprons, including a female fastener and a male fastener; The female buckle includes: A female buckle body, wherein a slot is provided on the female buckle body; The U-shaped clip is provided on the main body of the female buckle and has a clamping groove suitable for insertion into the edge of the lead apron body; The first clamping member is movably mounted on one side inner wall of the clamping groove; it has a first clamping state that can clamp the lead apron body inserted into the clamping groove against the inner wall of the other side of the clamping groove, and a first relaxed state that no longer clamps the lead apron body inserted into the clamping groove. The public deduction includes: The main body of the male buckle has a threading channel for the lead apron strap to pass through; The second clamping member is movably installed on the inner wall of one side of the threading channel. It has a second clamping state that can clamp the lead apron strap passing through the threading channel to the inner wall of the other side of the threading channel, and a second loosening state that no longer clamps the lead apron strap passing through the threading channel. The plug is located at one end of the male buckle body and can be detachably inserted into the slot.

[0007] Furthermore, the plug is U-shaped, including a first straight section and a second straight section arranged opposite to each other, and a curved section connected to one end of the first straight section and one end of the second straight section respectively. The other end of the first straight section is fixedly connected to the male buckle body, and the other end of the second straight section is provided with a snap-fit ​​part. The side wall of the female buckle body is provided with a pressing port that communicates with the slot. The position of the pressing port is spatially offset from the clamping groove of the U-shaped clip, so that the pressing port can be directly operated when the U-shaped clip clamps the lead apron body. When the plug is inserted into the slot, the latching part is squeezed by the inner wall of the slot, which in turn drives the second straight section to elastically deform. When the latching part moves to the position corresponding to the pressing port, the second straight section is reset under the elastic restoring force of the U-shaped structure, which drives the latching part to be inserted into the pressing port to achieve mechanical locking. When pressure is applied to the latching part through the pressing port, the latching part can be driven to retract from the pressing port into the slot, thereby unlocking.

[0008] Furthermore, the latching part is wedge-shaped, and its thickness gradually increases along the direction from one end to the other end of the second straight section, and the outer wall surface of the latching part is inclined. The width of the slot in the thickness direction of the latching part is slightly greater than the distance between the outer side of the first straight section and the outer side of the second straight section, and slightly less than the distance between the outer side of the second straight section and the outer wall surface of the thickest part of the latching part.

[0009] Furthermore, the U-shaped clip is disposed on the side of the female buckle body opposite to the pressing port, including a first side wall and a second side wall disposed opposite to each other, and a bottom wall connecting the first side wall and the second side wall; The first sidewall and the female buckle body are integrally formed, and the second sidewall is disposed opposite to the female buckle body; The female buckle body has a first threaded hole opposite to the pressing port. One end of the first threaded hole is connected to the slot, and the other end passes through the first side wall and is connected to the clamping groove. The first clamping member has an external thread that matches the first threaded hole, and a first driving structure is provided at one end facing the pressing port, and the end end does not extend into the slot in the first clamping state.

[0010] Furthermore, a first friction pad is provided inside the second sidewall.

[0011] Furthermore, the male buckle body has a second threaded hole that penetrates the through-passage, the second clamping member has an external thread that matches the second threaded hole, and a second driving structure is provided at the end away from the through-passage.

[0012] Furthermore, the first driving structure and / or the second driving structure is a slotted groove or a cross-shaped groove.

[0013] Furthermore, it also includes: The extrusion plate is movably installed inside the through-channel and can move along the axial direction of the second clamping member; Rotating the second clamping member can drive the extrusion plate to move, thereby pressing or releasing the lead apron strap passing through the threading channel; Preferably, the side of the extrusion plate opposite to the second clamping member is provided with an anti-slip structure.

[0014] Furthermore, two limiting guide grooves are opened on the two side walls of the male buckle body that are perpendicular to the moving direction of the extrusion plate, and two guide protrusions are respectively provided at both ends of the extrusion plate, and the two guide protrusions slide in cooperation with the two limiting guide grooves.

[0015] Furthermore, the extrusion plate is formed by splicing two half-push plates together, and the two guide protrusions are respectively disposed on the two half-push plates.

[0016] The technical solution provided by this utility model has the following advantages: This utility model discloses an adjustable auxiliary fastening device for lead aprons, comprising a female fastener and a male fastener. The female fastener includes a female fastener body, a U-shaped clip, and a first tightening member. The female fastener body has a slot. The U-shaped clip is disposed on the female fastener body and has a clamping groove suitable for insertion of the edge of the lead apron body. The first tightening member is movably mounted on the inner wall of one side of the clamping groove. It has a first tightening state capable of pressing the lead apron body inserted into the clamping groove against the inner wall of the other side of the clamping groove, and a first loosening state where the lead apron body inserted into the clamping groove is no longer pressed. The male fastener includes a male fastener body, a second tightening member, and a plug. The male fastener body has a threading channel for the lead apron strap to pass through. The second tightening member is movably mounted on the inner wall of one side of the threading channel. It has a second tightening state capable of pressing the lead apron strap passing through the threading channel against the inner wall of the other side of the threading channel, and a second loosening state where the lead apron strap passing through the threading channel is no longer pressed. The plug is disposed at one end of the male fastener body and can be detachably inserted into the slot.

[0017] In this invention, when the Velcro detaches, the edge of the lead apron body can be inserted into the clamping groove of the U-shaped clip of the female buckle, and then fixed by adjusting the first tightening member. Simultaneously, the lead apron strap is passed through the threading channel of the male buckle, and then fixed by adjusting the second tightening member. When it is necessary to close the lead apron, the plug of the male buckle is aligned with the slot of the female buckle and inserted to connect the two parts. The male buckle can then be pulled out of the female buckle to separate them.

[0018] This utility model discloses an adjustable auxiliary fastening device for lead aprons, providing a mechanical connection solution that requires no perforation and is non-destructive to install. Compared to traditional Velcro, this device, through a U-shaped clip and a threading channel, can be "attached" to the existing lead apron structure without modifying the lead apron body or the original strap fixing method, thus avoiding the risk of damage caused by modification. The detachable design of the plug and slot allows the male and female fasteners to be easily separated and reconnected, improving the reusability of the device. Attached Figure Description

[0031] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] This embodiment provides an adjustable auxiliary fastening device for lead aprons, such as... Figure 1-7 As shown, it includes a female buckle 1 and a male buckle 2; the female buckle 1 includes a female buckle body 11, a U-shaped clip 12, and a first tightening member 13; the female buckle body 11 is provided with a slot 111; the U-shaped clip 12 is disposed on the female buckle body 11 and has a clamping groove 121 suitable for insertion of the edge of the lead apron body; the first tightening member 13 is movably installed on one inner wall of the clamping groove 121; it has a first tightening state that can press the lead apron body inserted into the clamping groove 121 against the inner wall of the other side of the clamping groove 121, and a first loosening state that no longer presses against the lead apron body inserted into the clamping groove 121. The male buckle 2 includes a male buckle body 21, a second tightening member 22, and a plug 23. The male buckle body 21 has a threading channel 211 through which the lead apron strap passes. The second tightening member 22 is movably installed on the inner wall of one side of the threading channel 211 and has a second tightening state that can tighten the lead apron strap passing through the threading channel 211 against the inner wall of the other side of the threading channel 211, and a second loosening state that no longer tightens the lead apron strap passing through the threading channel 211. The plug 23 is disposed at one end of the male buckle body 21 and can be detachably inserted into the slot 111.

[0033] In this embodiment, the female buckle 1 is clamped securely to the edge of the lead apron body 01 (such as the location of a failed Velcro) without damage, through a clamping mechanism consisting of its U-shaped clip 12 and the first tightening member 13. The male buckle 2 is clamped securely to the lead apron strap 02 without damage, through a fixing mechanism consisting of its insertion channel 211 and the second tightening member 22. The plug 23 of the male buckle 2 can be inserted into the slot 111 of the female buckle 1 for connection. The opening direction of the clamping groove 121 of the U-shaped clip 12 is opposite to the opening direction of the slot 111. Under normal circumstances, after the lead apron is worn on the body, it is fixed by attaching the Velcro on the lead apron strap 02 to the Velcro on the lead apron body 01. When the Velcro fails, the edge of the lead apron body 01 can be inserted into the clamping groove 121 of the U-shaped clip 12 of the female buckle 1, and then fixed by adjusting the first tightening member 13. Simultaneously, the lead apron strap 02 is passed through the threading channel 211 of the male buckle 2, and then fixed by adjusting the second tightening member 22. When it is necessary to close the lead apron, the plug 23 of the male buckle 2 is aligned with the slot 111 of the female buckle 1 and inserted to connect the two parts. The male buckle 2 is then pulled out of the female buckle 1 to separate them.

[0034] The adjustable auxiliary fastening device for lead aprons in this embodiment provides a mechanical connection solution that requires no perforation and is non-destructive to install. Compared to traditional Velcro, this device, through a U-shaped clip and a threading channel, can be "attached" to the existing lead apron structure without modifying the lead apron body or the original strap fixing method, avoiding the risk of damage caused by modification. The detachable design of the plug 23 and slot 111 allows the male and female fasteners to be easily separated and reconnected, improving the reusability of the device. This device can serve as a replacement or supplement to Velcro, extending the service life of the lead apron and ensuring protective safety.

[0035] The adjustable auxiliary fastening device for lead aprons in this embodiment further includes, for example: Figure 4 , 7As shown, the plug 23 is U-shaped, including a first straight section 231 and a second straight section 232 arranged opposite to each other, and a bent section 233 connected to one end of the first straight section 231 and one end of the second straight section 232 respectively. The other end of the first straight section 231 is fixedly connected to the male buckle body 21, and the other end of the second straight section 232 is provided with a snap-fit ​​part 234. The side wall of the female buckle body 11 has a pressing port 112 communicating with the slot 111. The position of the pressing port 112 is spatially offset from the clamping groove 121 of the U-shaped clip 12, so that when the U-shaped clip 12 clamps the lead apron body 01, the... The pressing port 112 can be directly operated; when the plug 23 is inserted into the slot 111, the latching part 234 is squeezed by the inner wall of the slot 111, thereby driving the second straight section 232 to elastically deform. When the latching part 234 moves to the position corresponding to the pressing port 112, the second straight section 232 is reset under the elastic restoring force of the U-shaped structure, driving the latching part 234 to engage in the pressing port 112, thereby achieving mechanical locking; when pressure is applied to the latching part 234 through the pressing port 112, the latching part 234 can be driven to retract from the pressing port 112 into the slot 111, thereby achieving unlocking.

[0036] In this embodiment, the plug 23 adopts a U-shaped structure. The first straight section 231 is fixed to the male buckle body 21, and the other end of the second straight section 232 is provided with a latching part 234. A pressing hole 112 is provided on the side wall of the female buckle body 11, and the position of the pressing hole is designed so that it will not be blocked by the lead apron. The shape inside the slot 111 matches the U-shaped structure of the plug. When the U-shaped plug 23 is inserted into the slot 111, the latching part 234 will be squeezed by the inner wall of the slot, causing the U-shaped arm to elastically deform inward. When the plug continues to be inserted, when the latching part 234 moves to the position corresponding to the pressing hole 112, the second straight section 232 will spring outward under the elastic restoring force of the U-shaped structure, and the latching part will engage with the pressing hole to achieve locking. When the user needs to separate, he / she can directly press the latching part 234 through the pressing hole 112 to force it to return to its original position (back into the slot) from the pressing hole 112, and then pull out the plug to achieve unlocking. Featuring a U-shaped plug with a snap-lock design, the apron automatically locks itself in place upon insertion, eliminating the need for additional locking actions and improving ease of operation. This mechanical locking mechanism effectively prevents the lead apron from accidentally falling off during activity, enhancing the reliability of the protection.

[0037] The adjustable auxiliary fastening device for lead aprons in this embodiment, such as... Figure 4As shown, the latching portion 234 is wedge-shaped, and its thickness gradually increases from one end to the other end of the second straight section 232, and the outer wall surface of the latching portion 234 is inclined; the width of the slot 111 in the thickness direction of the latching portion 234 is slightly greater than the distance between the outer side surface of the first straight section 231 and the outer side surface of the second straight section 232, and slightly smaller than the distance between the outer side surface of the second straight section 232 and the outer wall surface of the thickest part of the latching portion 234.

[0038] In this embodiment, the latching portion 234 is machined into a wedge shape, thin at the front end and thick at the base (along the axial direction of the second straight segment 232), and its outer wall is designed as a bevel to facilitate guidance and pressure during insertion. The width of the slot 111 (along the thickness direction of the latching portion 234) is precisely designed to be slightly smaller than the thickness of the latching portion when it is fully extended. This size ensures that the plug will inevitably be squeezed and deformed during insertion, and that it will have sufficient force to spring open and snap into place when it reaches the pressing port.

[0039] The adjustable auxiliary fastening device for lead aprons in this embodiment, such as... Figure 1-3 As shown, the U-shaped clip 12 is disposed on the side of the female buckle body 11 opposite to the pressing port 112, including a first sidewall 122 and a second sidewall 123 disposed opposite to each other, and a bottom wall 124 connecting the first sidewall 122 and the second sidewall 123; the first sidewall 122 and the female buckle body 11 are integrally formed, and the second sidewall 123 is disposed opposite to the female buckle body 11; the female buckle body 11 is provided with a first threaded hole 113 opposite to the pressing port 112, one end of the first threaded hole 113 communicates with the slot 111, and the other end passes through the first sidewall 122 and communicates with the clamping groove 121; the first tightening member 13 is provided with an external thread that matches the first threaded hole 113, and a first driving structure is provided at one end facing the pressing port 112, and this end does not extend into the slot 111 in the first tightening state.

[0040] In this embodiment, the U-shaped clip 12 and the female buckle body 11 adopt an integrated structural design, which enhances the overall strength. The first threaded hole 113 penetrates both the female buckle body and the first sidewall 122 of the U-shaped clip, connecting the two spaces, slot 111 and clamping groove 121. The first tightening member 13 has an external thread and can be screwed into the first threaded hole 113. The end facing the pressing port 112 is the first driving structure used to drive the first tightening member 13 to rotate, and the user can operate the first driving structure through the pressing port 112. When the first tightening member 13 is tightened, its end extends into the clamping groove 121, pressing the lead apron body against the opposite second sidewall 123 to achieve clamping, and the first tightening member 13 is in the first tightened state. At this time, the end facing the pressing port 112 (slot 111) will not extend into the slot 111 to ensure that the plug is not obstructed when inserted. In some lead aprons, the apron straps are angled. In this case, the inner wall of the bottom wall 124 can form a certain angle with the axial direction of the slot 111, that is, the inner wall of the bottom wall 124 can form a certain angle with the insertion direction of the plug. In this way, the lead apron straps will not twist after using this device. It should be noted that the adjustable auxiliary fastening device for lead aprons described in this embodiment, whether used on the left or right edge of the lead apron body, can be compatiblely adjusted by changing the orientation or installation direction of the corresponding components to match the Velcro contour of the lead apron body, thereby achieving a secure clamping.

[0041] In this embodiment, the adjustable auxiliary fastening device for lead apron further includes a first friction pad 125 disposed inside the second sidewall 123.

[0042] In this embodiment, a first friction pad 125 made of rubber or silicone is attached or embedded on the inner side of the second sidewall 123 of the U-shaped clip. The first friction pad 125 provides a contact surface with a high coefficient of friction, preventing the lead apron body from sliding or shifting during use.

[0043] The adjustable auxiliary fastening device for lead aprons in this embodiment further includes, for example: Figure 4 As shown, the male buckle body 21 has a second threaded hole 212 that passes through the through-pass channel 211, the second clamping member 22 has an external thread that matches the second threaded hole 212, and a second driving structure is provided at one end away from the through-pass channel 211.

[0044] In this embodiment, the second clamping member 22 has an external thread and can be screwed into the second threaded hole 212. A second driving structure is provided at the end away from the threaded passage 211 for user operation. The axial movement of the second clamping member 22 is achieved through the threaded pair, clamping the passing lead apron strap within the threaded passage 211.

[0045] The adjustable auxiliary fastening device for lead aprons in this embodiment further includes, for example: Figure 2 ,3 As shown, the first driving structure and / or the second driving structure is a slotted groove or a cross-shaped groove.

[0046] In this embodiment, the first driving structure and the second driving structure can be respectively configured as a slotted groove (which can be turned with a flathead screwdriver) or a Phillips head groove (which can be turned with a Phillips head screwdriver).

[0047] The adjustable auxiliary fastening device for lead aprons in this embodiment, such as... Figure 5 As shown, it also includes a wrench 3, having a drive portion that matches the slotted groove or the cross groove. The size of the wrench 3 matches the pressing port 112, allowing it to be operated via the pressing port 112.

[0048] In this embodiment, the wrench 3 can be used together for easy carrying.

[0049] The adjustable auxiliary fastening device for lead aprons in this embodiment further includes a pressing plate 24, which is movably installed inside the threading channel 211 and can move along the axial direction of the second tightening member 22; rotating the second tightening member 22 can drive the pressing plate 24 to move, so as to press or loosen the lead apron strap passing through the threading channel 211; preferably, the side of the pressing plate 24 facing away from the second tightening member 22 is provided with an anti-slip structure.

[0050] In this embodiment, the extrusion plate and the second clamping member are in contact and engaged. The end of the second clamping member 22 acts on the extrusion plate, rather than directly pressing the strap. The side of the extrusion plate that contacts the strap can be provided with anti-slip texture or a pad. After the lead apron strap passes through the threading channel 211, the second drive structure is operated to drive the second clamping member 22 to rotate. The second clamping member 22 moves axially, thereby pushing the extrusion plate 24 to move, thus pressing the strap. The anti-slip structure can be a second friction pad 25 made of rubber or silicone material that is pasted or embedded in the extrusion plate. The second friction pad 25 has the same or similar structure as the first friction pad 125.

[0051] The adjustable auxiliary fastening device for lead aprons in this embodiment, such as... Figure 1 , 4 As shown, the male buckle body 21 has two limiting guide grooves 213 on its two side walls that are perpendicular to the moving direction of the extrusion plate 24. The two ends of the extrusion plate 24 are respectively provided with two guide protrusions 241, and the two guide protrusions 241 slide in cooperation with the two limiting guide grooves 213.

[0052] In this embodiment, the extension direction of each sidewall is parallel to the movement direction of the extrusion plate 24, and the extension direction of the limiting guide groove 213 is parallel to the movement direction of the extrusion plate 24, and can cover the entire stroke of the extrusion plate 24. The shape of the guide protrusion 241 matches that of the limiting guide groove 213. When the extrusion plate 24 is installed inside the threading channel 211, its guide protrusion 241 will slide into the limiting guide groove 213 of the male buckle body 21. The guide protrusion 241 slides in the limiting guide groove 213 and cannot rotate or tilt.

[0053] The adjustable auxiliary fastening device for lead aprons in this embodiment further includes, for example: Figure 4 As shown, the extrusion plate 24 is formed by splicing two half-push plates 242 together, and the two guide protrusions 241 are respectively disposed on the two half-push plates 242.

[0054] In this embodiment, the extrusion plate 24 is composed of two independent half-push plates 242 spliced ​​together, each half-push plate having a guide protrusion 241. The two half-push plates 242 are respectively provided with splicing joints that can be spliced ​​together. The two splicing joints can be spliced ​​and engaged, so that the two half-push plates 242 are glued together after being installed into the male buckle body 21, which is convenient for production and use.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
