Description

Technical Field

[0001] This invention belongs to the field of medical device manufacturing technology, specifically relating to a rotatable handle structure for portable emergency equipment. Background Technology

[0002] Portable emergency medical equipment is a core component in scenarios such as out-of-hospital emergency care, field rescue, and disaster relief. In addition to having stable medical functions, its core usage requirements also include being lightweight, portable, and adaptable to different spaces. Rescuers often need to quickly transfer equipment in confined spaces (such as ambulance compartments, elevators, and caves in the wild) or move the equipment while operating it with one hand. This places extremely high demands on the design of the equipment's handle.

[0003] In actual rescue scenarios, some portable first aid devices integrate more modules, and the top needs to accommodate core functional components such as displays, operation buttons, and electrode interfaces, resulting in insufficient space on the top of the device to accommodate traditional handles. At the same time, during field rescues, the devices often need to be placed on irregular ground, and the folded state of the handles needs to avoid taking up extra space or causing the device to tip over. These practical needs make the traditional handle structure face significant limitations.

[0004] Therefore, there is an urgent need to provide a rotating handle structure for portable first aid equipment to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a rotatable handle structure for portable first aid equipment.

[0006] The technical solution adopted to solve the above technical problems is: to provide a rotatable handle structure for portable first aid equipment, including a medical device, wherein a symmetrical handle base is fixedly installed on the surface of the medical device, and a handle is rotatably connected to the surface of the handle base, and further includes;

[0007] A positioning mechanism is fixedly installed between the handle and the handle base. The positioning mechanism is used to fix the position of the handle after the handle is rotated. A first shaft pin is detachably installed between the handle and the handle base.

[0008] A second shaft pin is fixedly connected to one side of the handle. The second shaft pin is rotatably connected inside the handle base. The first shaft pin and the second shaft pin are used to assist the handle in rotating around the handle base. A connecting mechanism is detachably installed between the positioning mechanism, the handle, and the handle base. The connecting mechanism is used to connect the positioning mechanism, the handle, and the handle base.

[0009] The present invention is further configured such that: a hand-held part is fixedly installed at one end of the handle, the surface of the hand-held part is provided with multiple anti-slip textures, and two insertion holes are provided on one side of the handle.

[0010] With the above technical solution, the two handles can be rotated by holding the hand part. When the two handles are put together, they form a grip position to lift the medical device. When the two handles are separated, the handles are put together with the back of the medical device to form a storage state, which does not affect the use of the medical device. The anti-slip texture increases the friction between the hand part and the palm, preventing the medical device from slipping when lifted.

[0011] The invention is further configured such that the two sockets are arranged in a ring around the center point of the other end of the handle, and the included angle between the two sockets is 135 degrees.

[0012] The above technical solution provides two sockets. When the two handles are in a retracted position with the back of the medical device, the insertion rod is inserted into one socket. When the two handles are rotated to form a gripping position, the insertion rod is inserted into the other socket. The handles rotate 135 degrees from the retracted position to the gripping position.

[0013] The present invention is further configured such that: the positioning mechanism includes a positioning wrench, a groove is provided on one side of the positioning wrench, and a plug rod is fixedly installed on the other side of the positioning wrench, the plug rod being movably inserted into two plug holes.

[0014] With the above technical solution, when in storage, the plug rod is inserted into one socket. When it is necessary to turn the handle, the positioning wrench is pulled outward, and the plug rod is moved out of one socket. At this time, the handle can be rotated. After rotating 135 degrees, the two handles form a gripping position. The positioning wrench is released, and the plug rod is inserted into the other socket, thus fixing the position of the handle.

[0015] The present invention is further configured such that: a groove is provided inside the second shaft pin, and a locking spring is fixedly installed on the inner wall of the groove.

[0016] Through the above technical solution, the second shaft pin cooperates with the first pin to enable the handle to rotate around the handle seat, the slide groove is used for the movement of the slider, and the locking spring cooperates with the positioning wrench to fix the handle. When the locking spring is squeezed, the plug rod moves out of one plug hole and the handle can rotate. When the locking spring returns to its original position, the plug rod is inserted into another plug hole to fix the handle.

[0017] The present invention is further configured such that: the connecting mechanism includes a connecting rod, one end of which is fixedly mounted with a slider, both the connecting rod and the slider are slidably connected inside the groove, the slider is circular and the outer diameter of the slider is the same as the inner diameter of the groove, and the outer wall of the slider is movably fitted with the inner wall of the groove.

[0018] With the above technical solution, when it is necessary to turn the handle, the positioning wrench is pulled outward. At this time, the insertion rod moves out of one of the insertion holes, which further drives the connecting rod and the slider to slide inside the slide groove. At this time, the locking spring is compressed, and the handle can be rotated after it is no longer restricted. After the two handles are rotated 135 degrees and fit together to form a gripping position, the positioning wrench is released, the locking spring rebounds, and the positioning wrench moves back to the initial position. The insertion rod is inserted into the other insertion hole to fix the handle.

[0019] The invention is further configured such that the other end of the locking spring is in contact with the surface of the slider, and the connecting rod passes through the interior of the locking spring.

[0020] With the above technical solution, the locking spring is located inside the slide groove and connected to the inner wall of the slide groove, and the other end is in contact with the surface of the slider, playing the role of energy storage and release.

[0021] The invention is further configured such that: the other end of the connecting rod extends into the groove, and the surface of the other end of the connecting rod is provided with an external thread, and a nut is threadedly connected to the surface of the external thread, and the nut is rotatably connected inside the groove.

[0022] With the above technical solution, when the nut is unscrewed from the surface of the connecting rod, the connecting rod and the slider can be moved out from the inside of the second shaft pin and separated. After the nut and the connecting rod form a whole, the handle can be fixed after the handle is rotated.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The present invention is equipped with a handle, which is arranged on the back plane of the medical device, avoiding the top functional component area, thus fundamentally solving the space occupation conflict problem. The back mounting surface is a planar structure, which provides stable support for the rotation and storage of the handle.

[0025] 2. The present invention is provided with a first axle pin and a second axle pin. The handle body is connected to the carrying handle of the medical device through the first axle pin and the second axle pin. The axes of the first axle pin and the second axle pin are parallel to the back of the medical device, so that the handle can be rotated 135° controllably around the axis between the "storage position" and the "grip position". The grip position is designed with the center of gravity matching: the handle rotates to the upper area of ​​the medical device to adapt to the "hand-held device" of the rescue personnel.

[0026] 3. The present invention is provided with a positioning mechanism and a connecting mechanism. A locking spring, a plug rod and a plug hole are provided at the connection between the first shaft pin, the second shaft pin and the handle seat. When the handle is rotated to the storage state or the gripping position, the plug rod is inserted into the corresponding plug hole to achieve stable locking of the handle and prevent accidental rotation during use or storage. The locked state can be released by rotating the handle with a slight external force. The operation is convenient and does not require additional tools. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] Please see Figures 1-6 This application provides a rotatable handle structure for a portable first aid device, including a medical device 1, a symmetrical handle base 2 fixedly mounted on the surface of the medical device 1, and a handle 3 rotatably connected to the surface of the handle base 2.

[0036] like Figure 3 and Figure 5 As shown, a hand-held part 31 is fixedly installed at one end of the handle 3. The surface of the hand-held part 31 is provided with multiple anti-slip textures 32, and two insertion holes 33 are provided on one side of the handle 3.

[0037] In this embodiment, by holding the hand-held part 31, the two handles 3 can be rotated. When the two handles 3 are put together, they form a grip position to lift the medical device 1. When the two handles 3 are separated, the handles 3 are put together with the back of the medical device 1 to form a storage state, which does not affect the use of the medical device 1. The anti-slip texture 32 increases the friction between the hand-held part 31 and the palm, preventing the medical device 1 from slipping when lifted.

[0038] like Figure 3 and Figure 5 As shown, the two sockets 33 are arranged in a ring around the center point of the other end of the handle 3, and the included angle between the two sockets 33 is 135 degrees.

[0039] In this embodiment, two sockets 33 are provided. When the two handles 3 are in a retracted state with the back of the medical device 1, the plug rod 43 is inserted into one socket 33. When the two handles 3 are rotated to form a gripping position, the plug rod 43 is inserted into the other socket 33. The handles 3 are rotated 135 degrees from the retracted state to the gripping position.

[0040] A positioning mechanism 4 is fixedly installed between the handle 3 and the handle base 2. The positioning mechanism 4 is used to fix the position of the handle 3 after the handle 3 is rotated. A first shaft pin 5 is detachably installed between the handle 3 and the handle base 2.

[0041] like Figure 6 As shown, the positioning mechanism 4 includes a positioning wrench 41. A groove 42 is provided on one side of the positioning wrench 41, and a plug rod 43 is fixedly installed on the other side of the positioning wrench 41. The plug rod 43 is movably inserted into the two plug holes 33.

[0042] In this embodiment, when in the storage state, the insertion rod 43 is inserted into one insertion hole 33. When it is necessary to rotate the handle 3, the positioning wrench 41 is pulled outward, and the insertion rod 43 is moved out of one insertion hole 33. At this time, the handle 3 can be rotated. After rotating 135 degrees, the two handles 3 form a gripping position. The positioning wrench 41 is released, and the insertion rod 43 is inserted into the other insertion hole 33 to fix the position of the handle 3.

[0043] A second shaft pin 6 is fixedly connected to one side of the handle 3. The second shaft pin 6 is rotatably connected inside the handle base 2. The first shaft pin 5 and the second shaft pin 6 are used to assist the handle 3 in rotating around the handle base 2. A connecting mechanism 7 is detachably installed between the positioning mechanism 4, the handle 3 and the handle base 2. The connecting mechanism 7 is used to connect the positioning mechanism 4, the handle 3 and the handle base 2.

[0044] like Figure 6 As shown, a groove 61 is provided inside the second shaft pin 6, and a locking spring 62 is fixedly installed on the inner wall of the groove 61.

[0045] In this embodiment, the second pivot pin 6 cooperates with the first pivot pin 5 to allow the handle 3 to rotate around the handle seat 2. The slide groove 61 is used for the movement of the slider 72. The locking spring 62 cooperates with the positioning wrench 41 to fix the handle 3. When the locking spring 62 is squeezed, the insertion rod 43 moves out from one insertion hole 33, and the handle 3 can rotate. When the locking spring 62 returns to its original position, the insertion rod 43 is inserted into another insertion hole 33 to fix the handle 3.

[0046] like Figure 4 and Figure 6 As shown, the connecting mechanism 7 includes a connecting rod 71, and a slider 72 is fixedly installed at one end of the connecting rod 71. The connecting rod 71 and the slider 72 are slidably connected inside the slide groove 61. The slider 72 is circular and its outer diameter is the same as the inner diameter of the slide groove 61. The outer wall of the slider 72 is in contact with the inner wall of the slide groove 61.

[0047] In this embodiment, when it is necessary to rotate the handle 3, the positioning wrench 41 is pulled outward. At this time, the insertion rod 43 moves out of one insertion hole 33, which further drives the connecting rod 71 and the slider 72 to slide inside the slide groove 61. At this time, the locking spring 62 is squeezed, and the handle 3 can be rotated after it is no longer restricted. After the two handles 3 rotate 135 degrees and fit together to form a gripping position, the positioning wrench 41 is released, the locking spring 62 rebounds, and the positioning wrench 41 moves back to the initial position. The insertion rod 43 is inserted into the other insertion hole 33 to fix the handle 3.

[0048] like Figure 4 and Figure 6 As shown, the other end of the locking spring 62 is in contact with the surface of the slider 72, and the connecting rod 71 passes through the interior of the locking spring 62.

[0049] In this embodiment, the locking spring 62 is located inside the slide groove 61 and connected to the inner wall of the slide groove 61, and the other end is in contact with the surface of the slider 72, so as to play the role of storing and releasing energy.

[0050] like Figure 4 and Figure 6 As shown, the other end of the connecting rod 71 extends into the groove 42. The surface of the other end of the connecting rod 71 is provided with an external thread 73. A nut 74 is threadedly connected to the surface of the external thread 73. The nut 74 is rotatably connected inside the groove 42.

[0051] In this embodiment, when the nut 74 is unscrewed from the surface of the connecting rod 71, the connecting rod 71 and the slider 72 can be moved out of the second shaft pin 6 as a whole, thus achieving separation. After the nut 74 and the connecting rod 71 form a whole, the handle 3 can be fixed after the handle 3 is rotated.

[0052] The working principle of this embodiment is as follows: When it is necessary to rotate the handle 3, firstly, the positioning wrench 41 is pulled outward. At this time, the insertion rod 43 moves out from the inside of one insertion hole 33, further driving the connecting rod 71 and the slider 72 to slide inside the slide groove 61. At this time, the locking spring 62 is squeezed, and the handle 3 can be rotated after it is no longer restricted. After the two handles 3 are rotated 135 degrees and fit together to form a gripping position, the positioning wrench 41 is released, the locking spring 62 rebounds, and the positioning wrench 41 is moved back to the initial position. The insertion rod 43 is inserted into the other insertion hole 33 to fix the handle 3. Holding the handle 3 can stably transport the medical device 1. After the medical device 1 is placed stably, the positioning wrench 41 is pulled outward again, and the two handles 3 are rotated back to the storage state.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
