Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and particularly relates to a medical device and a locking control device. Background Art

[0002] In actual application scenarios of existing medical devices, there are often situations where the host needs to be installed or disassembled from the bracket. Taking first-aid ventilation devices as an example, in a general solution, the host and the equipped gas cylinder need to be fixed on the bracket. When the host needs to be decoupled from other modules (bracket or gas cylinder) and used alone to achieve portability and rapid transfer, such a solution cannot achieve the rapid separation of the host from the bracket, nor can it achieve the rapid installation of the host on the bracket after the host returns. That is, existing medical devices cannot achieve the function of quickly locking and unlocking the host from the bracket. Summary of the Invention

[0003] The main purpose of the present invention is to provide a locking control device capable of quickly locking and unlocking the host from the bracket, and a medical device equipped with the locking control device.

[0004] In a first aspect, in one embodiment, a locking control device is provided, including:

[0005] A base;

[0006] A locking member, the locking member is movably arranged on the base, and the locking member can move between a locked position and an unlocked position;

[0007] A switch member, the switch member is rotatably connected to the base;

[0008] A transmission assembly, the transmission assembly includes a first transmission member and a second transmission member. One end of the first transmission member is rotatably connected to the switch member, and the other end is rotatably connected to the second transmission member; the second transmission member is rotatably connected to the base, and the second transmission member is movably connected to the locking member; when the switch member rotates relative to the base, the locking member is driven to move between the locked position and the unlocked position through the first transmission member and the second transmission member; the base, the switch member, the first transmission member and the second transmission member together form a four-bar linkage mechanism.

[0009] In one embodiment, the four-bar linkage mechanism has a self-locking position; during the process of the locking member moving from the locked position to the unlocked position, or from the unlocked position to the locked position, the four-bar linkage mechanism will pass through the self-locking position.

[0010] In one embodiment, the position where the switch member is rotatably connected to the base body is the first hinge point, the position where the switch member is rotatably connected to the first transmission member is the second hinge point, and the position where the first transmission member is rotatably connected to the second transmission member is the third hinge point; when the four-bar linkage mechanism is in the self-locking position, the first hinge point, the second hinge point, and the third hinge point are on the same straight line.

[0011] In one embodiment, the second transmission member is configured as a rotating disc, the rotating disc has a chute, and the locking member is provided with a roller, and the roller is movably arranged in the chute; when the rotating disc rotates relative to the base body, it drives the roller to move in the chute, so that the roller drives the locking member to move between the locked position and the unlocked position.

[0012] In one embodiment, the rotating disc has two such chutes, and the two chutes are respectively arranged on opposite sides of the rotating disc, and the distances from both ends of each chute to the axis of the rotating disc are different; the locking member is configured as two, and the two chutes are movably sleeved with the rollers on the two locking members in a one-to-one correspondence.

[0013] In one embodiment, when the switch member rotates in the first direction, it drives the second transmission member to rotate in the second direction through the first transmission member, so that the chute of the second transmission member drives the locking member to move towards the unlocked position through the roller; when the switch member rotates in the second direction, it drives the second transmission member to rotate in the first direction through the first transmission member, so that the chute of the second transmission member drives the locking member to move towards the locked position through the roller; the first direction is opposite to the second direction.

[0014] In one embodiment, the base body has a locking hole, the locking member has a locking tongue, and the locking member can make a linear motion between the locked position and the unlocked position; when the locking member moves to the locked position, the locking tongue extends out of the locking hole; when the locking member moves to the unlocked position, the locking tongue retracts into the locking hole.

[0015] In one embodiment, the locking member has two such locking tongues, and the two locking tongues are on the same side of the locking member; when the locking member moves to the locked position, both locking tongues extend into the locking hole; when the locking member moves to the unlocked position, both locking tongues withdraw from the locking hole.

[0016] In one embodiment, it further includes a first elastic member. One end of the first elastic member is connected to the base body, and the other end is connected to the locking member. The elastic restoring force of the first elastic member is used to assist the locking member in staying at the locked position. The base body has an abutting portion, and the abutting portion is located on the rotation path when the switch member drives the locking member to move towards the locked position. When the locking member is at the locked position, the elastic restoring force of the first elastic member acting on the locking member is transmitted to the switch member through the rotating disc and the first transmission member in sequence, so that the switch member abuts tightly against the abutting portion.

[0017] In one embodiment, the locking member further includes a guiding groove, and the guiding groove extends along the movement direction of the locking tongue. The base body has a guiding post, and the guiding groove is movably sleeved on the guiding post.

[0018] In one embodiment, the switch member has a switch portion and a connecting portion, and the connecting portion is rotatably connected to the first transmission member. The outer wall of the base body has a switch groove, and the switch portion is arranged in the switch groove. The switch member can rotate relative to the base body so that the switch portion extends out of or retracts into the switch groove.

[0019] In one embodiment, it further includes a cover body, and the cover body is movably connected to the base body. The cover body can move relative to the base body to open and close the switch groove.

[0020] In one embodiment, the base body has a positioning groove, and the positioning groove has an opening facing the cover body. A second elastic member and a positioning ball head are arranged in the positioning groove. One end of the second elastic member abuts against the inner wall of the positioning groove, and the other end abuts against the positioning ball head. The elastic restoring force of the second elastic member is used to drive the positioning ball head to move towards the opening of the positioning groove, so that a part of the positioning ball head extends out of the opening of the positioning groove. The cover body has a first clamping groove and a second clamping groove. When the cover body opens the switch groove, the first clamping groove is clamped with the positioning ball head. When the cover body closes the switch groove, the second clamping groove is clamped with the positioning ball head.

[0021] In a second aspect, in one embodiment, a medical device is provided, including a host, a bracket, and the lock control device as described in any one of the above. The lock control device is arranged between the host and the bracket and is connected to the bracket. When the locking member moves to the locked position, the lock control device locks the host and the bracket. When the locking member moves to the unlocked position, the lock control device releases the locking of the host.

[0022] According to the medical device and the locking device of the above embodiments, the locking device includes a base body, a locking member, a switching member, and a transmission assembly. The locking member is movably arranged on the base body and can move between a locked position and an unlocked position. The switching member is rotatably connected to the base body. The transmission assembly includes a first transmission member and a second transmission member. One end of the first transmission member is rotatably connected to the switching member, and the other end is rotatably connected to the second transmission member. The second transmission member is rotatably connected to the base body and is movably connected to the locking member. When the switching member rotates relative to the base body, the locking member is driven to move between the locked position and the unlocked position through the first transmission member and the second transmission member. The base body, the switching member, the first transmission member, and the second transmission member together form a four-bar linkage mechanism. On the one hand, the operator can drive the first transmission member and the second transmission member to move by rotating the switching member, and further drive the locking member to move between the locked position and the unlocked position, so as to realize the quick locking and unlocking of the locking device. When the locking device is applied to a medical device, the quick locking and quick disassembly of the host and the bracket of the medical device can be realized. On the other hand, since the base body, the switching member, the first transmission member, and the second transmission member together form a four-bar linkage mechanism, the four-bar linkage mechanism needs to be linked during the locking and unlocking processes of the locking device, making it not easy for the locking device to be accidentally unlocked under the action of external vibration or impact, which is beneficial to improving the reliability of the locking device.

Detailed Description of the Invention

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. Similar elements in different embodiments are denoted by related similar reference numerals. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods.

[0034] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean an essential sequence unless it is stated that a certain sequence must be followed.

[0035] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The terms "connection" and "coupling" used in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0036] This embodiment provides a medical device.

[0037] Please refer to Figures 1-9 , the medical device includes a main unit 800, a bracket (not shown), and a locking control device.

[0038] Please refer to Figures 1-5 , the locking control device is disposed between the main unit 800 and the bracket and is connected to the bracket. When the locking member 200 moves to the locking position, the locking control device locks the main unit 800 to the bracket. When the locking member 200 moves to the unlocking position, the locking control device releases the locking of the main unit 800.

[0039] When it is necessary to disassemble the main unit 800 from the bracket, the staff can first move the locking member 200 of the locking control device to the unlocking position, and then disassemble the main unit 800 from the bracket. After the staff installs the main unit 800 on the bracket, it is necessary to move the locking member 200 of the locking control device to the locking position, so as to lock the main unit 800 to the bracket through the locking control device.

[0040] On the other hand, this embodiment also provides a locking control device.

[0041] This locking control device can be applied to the above-mentioned medical device, or can be applied to a door body or other devices that require the use of a locking control device.

[0042] Please refer to Figures 1-5 , the locking control device includes a base body 100, a locking member 200, a switch member 300, and a transmission assembly 400.

[0043] The bottom of the base body 100 is fixedly connected to the bracket (not shown). The locking member 200 is movably disposed on the top of the base body 100 and is used to lock the main unit 800 to the top of the base body 100. The transmission assembly 400 is disposed at the bottom of the base body 100. However, this application is not limited thereto, and the transmission assembly 400 can be disposed on the top of the base body 100.

[0044] The locking member 200 is capable of moving between a locked position and an unlocked position. The switching member 300 is rotatably connected to the base body 100. The transmission assembly 400 includes a first transmission member 410 and a second transmission member 420. One end of the first transmission member 410 is rotatably connected to the switching member 300, and the other end is rotatably connected to the second transmission member 420. The second transmission member 420 is rotatably connected to the base body 100, and the second transmission member 420 is movably connected to the locking member 200. The position where the first transmission member 410 is rotatably connected to the second transmission member 420 is offset from the rotation axis of the second transmission member 420 on the base body 100. When the switching member 300 rotates relative to the base body 100, it drives the second transmission member 420 to rotate through the first transmission member 410 and the second transmission member 420, thereby driving the locking member 200 to move between the locked position and the unlocked position. The base body 100, the switching member 300, the first transmission member 410, and the second transmission member 420 together form a four-bar linkage mechanism.

[0045] On the one hand, the operator can drive the first transmission member 410 and the second transmission member 420 to move by rotating the switching member 300, thereby driving the locking member 200 to move between the locked position and the unlocked position, so that the quick locking and unlocking of the lock control device can be realized. When the lock control device is applied to a medical device, the quick locking and quick disassembly of the host 800 of the medical device and the bracket can be realized. On the other hand, since the base body 100, the switching member 300, the first transmission member 410, and the second transmission member 420 together form a four-bar linkage mechanism, the four-bar linkage mechanism needs to be linked during the locking and unlocking processes of the lock control device, making it difficult for the lock control device to be accidentally unlocked under the action of external vibration or impact, which is beneficial to improving the reliability of the lock control device.

[0046] Please refer to Figure 5 , in an embodiment, the four-bar linkage mechanism has a self-locking position. During the process of the locking member 200 moving from the locked position to the unlocked position or from the unlocked position to the locked position, the four-bar linkage mechanism will pass through the self-locking position.

[0047] During the process of the staff operating the lock control device to lock and unlock, the four-bar linkage mechanism will pass through the self-locking position. The staff needs to apply a relatively large force to drive the four-bar linkage mechanism to cross the self-locking position, so as to achieve the purpose of locking and unlocking the lock control device. In actual application scenarios, it is difficult for the force generated by external environmental vibration or impact to drive the four-bar linkage mechanism to cross the self-locking position, which further reduces the possibility of the lock control device being accidentally unlocked under the action of the external environment, and further benefits the improvement of the reliability of the lock control device.

[0048] Please refer to Figure 5, in one embodiment, the position where the switch member 300 is rotatably connected to the base body 100 is the first hinge point, the position where the switch member 300 is rotatably connected to the first transmission member 410 is the second hinge point, and the position where the first transmission member 410 is rotatably connected to the second transmission member 420 is the third hinge point. When the four-bar linkage is in the self-locking position, the first hinge point, the second hinge point, and the third hinge point are on the same straight line.

[0049] During the process of the staff operating the lock control device to lock and unlock, the first hinge point, the second hinge point, and the third hinge point of the four-bar linkage will all be in a state of being on the same straight line, so that the self-locking position needs to be crossed during the locking and unlocking processes of the lock control device. Specifically, please refer to Figure 5 , when the four-bar linkage is in the self-locking position, the first hinge point, the second hinge point, and the third hinge point are all located at Figure 5 the axis L1 in

[0050] Please refer to Figures 1-5 , in one embodiment, the second transmission member 420 is configured as a rotating disc 421, the rotating disc 421 has a chute 422, and a roller 500 is provided on the locking member 200. The roller 500 is movably arranged in the chute 422. When the rotating disc 421 rotates relative to the base body 100, it drives the roller 500 to move in the chute 422, so that the roller 500 drives the locking member 200 to move between the locked position and the unlocked position.

[0051] When the staff rotates the switch member 300, the switch member 300 drives the rotating disc 421 to rotate through the first transmission member 410, so that the rotating disc 421 drives the roller 500 to move in the chute 422, and further drives the locking member 200 to move between the locked position and the unlocked position through the roller 500. Specifically, the roller 500 is rotatably arranged on the locking member 200, so that the periphery of the roller 500 will rub against the inner wall of the chute 422, avoiding the situation that one side of the roller 500 wears faster, resulting in a reduction in the service life of the roller 500. However, the present application is not limited to this. The roller 500 can also be fixed to the locking member 200. When the switch member 300 drives the rotating disc 421 to rotate through the first transmission member 410, the roller 500 slides in the chute 422.

[0052] Please refer to Figures 1-5, in one embodiment, the rotating disc 421 has two sliding grooves 422, which are respectively arranged on opposite sides of the rotating disc 421 and are rotationally symmetric about the axis of the rotating disc 421. The distances from both ends of each sliding groove 422 to the axis of the rotating disc 421 are different. Two locking members 200 are configured, and the two sliding grooves 422 are movably sleeved with the rollers 500 on the two locking members 200 in a one-to-one correspondence. In the illustrated embodiment, the sliding groove 422 is a curved groove. The first transmission member 410 is in the shape of a non-linear rod. This shape can reduce interference during movement. However, the present application is not limited thereto. The first transmission member 410 can be linear, and the shape of the sliding groove 422 can be correspondingly changed. In the illustrated embodiment, the two sliding grooves 422 are rotationally symmetric about the axis of the rotating disc 421, which enables the two sliding grooves 422 to correspondingly drive the two locking members 200 to move synchronously to the locking position or the unlocking position when the rotating disc 421 rotates. Of course, in other embodiments, the arrangement of the two sliding grooves 422 is not limited to rotational symmetry, and the shape, size, and arrangement of the sliding groove 422 can also be adaptively changed according to actual needs, and the effect of driving the two locking members 200 to move synchronously to the locking position or the unlocking position can also be achieved.

[0053] When the rotating disc 421 rotates, the two sliding grooves 422 can drive the two rollers 500 to move simultaneously, and then drive the two locking members 200 to move between the locking position and the unlocking position through the two rollers 500. On the one hand, the two locking members 200 lock the host 800 from the left and right directions at the bottom of the host 800 respectively, so that the host 800 can be more firmly locked to the bracket. On the other hand, driving a plurality of rollers 500 to move by a single rotating disc 421 improves the transmission efficiency of the rotating disc 421. On the other hand, driving a plurality of rollers 500 to move simultaneously by a single rotating disc 421 results in good synchronism of the movement of the plurality of rollers 500, and also good synchronism of the locking and unlocking of the plurality of locking members 200.

[0054] Please refer to Figures 1-5 , in one embodiment, when the switch member 300 rotates in the first direction, it drives the second transmission member 420 to rotate in the second direction through the first transmission member 410, so that the sliding groove 422 of the second transmission member 420 drives the locking member 200 to move to the unlocking position through the roller 500. When the switch member 300 rotates in the second direction, it drives the second transmission member 420 to rotate in the first direction through the first transmission member 410, so that the sliding groove 422 of the second transmission member 420 drives the locking member 200 to move to the locking position through the roller 500. The first direction is opposite to the second direction.

[0055] When it is necessary to unlock the locking device, the staff can rotate the switch member 300 in the first direction. When the switch member 300 rotates in the first direction, it drives the second transmission member 420 to rotate in the second direction through the first transmission member 410, so that the chute 422 of the second transmission member 420 drives the locking member 200 to move towards the unlocking position through the roller 500, thereby realizing the unlocking of the locking device. When it is necessary to lock the locking device, the staff can rotate the switch member 300 in the second direction. When the switch member 300 rotates in the second direction, it drives the second transmission member 420 to rotate in the first direction through the first transmission member 410, so that the chute 422 of the second transmission member 420 drives the locking member 200 to move towards the locking position through the roller 500, thereby realizing the locking of the locking device. Specifically, in this embodiment, the first direction is Figure 4 the counterclockwise direction shown by the arrow R1 in Figure 4 and the second direction is the clockwise direction shown by the arrow R2 in. Of course, in other embodiments, the first direction can also be set as the clockwise direction, and at this time the second direction is correspondingly set as the counterclockwise direction.

[0056] Please refer to Figures 1-4 , 6 and 7. In one embodiment, the base body 100 has a locking hole 110, and the locking member 200 has a locking tongue 220. The locking member 200 can move linearly between the locking position and the unlocking position. When the locking member 200 moves to the locking position, the locking tongue 220 extends out of the locking hole 110 to cooperate with the corresponding structure on the host 800 placed on the base body 100 to lock the host 800. When the locking member 200 moves to the unlocking position, the locking tongue 220 retracts into the locking hole 110 and separates from the corresponding structure on the host 800.

[0057] Specifically, a receiving groove 170 is provided on the base body 100. The receiving groove 170 is located on the movement path of the locking tongue 220. A convex portion 810 is provided at the bottom of the host 800. When the host 800 is placed on the base body 100, the convex portion 810 is located in the receiving groove 170. A mating surface 811 is provided on one side of the convex portion 810 facing the locking tongue 220. When the locking tongue 220 extends out of the locking hole 110, it cooperates with the mating surface 811 to lock. When the locking tongue 220 retracts into the locking hole 110, it separates from the mating surface 811. Other mating structures can also be adopted in this application. Specifically, in this embodiment, the mating surface 811 is located Figure 7 above the convex portion 810 in. In other embodiments, the mating surface 811 can also be located on the side of the convex portion 810 or other suitable positions.

[0058] When the locking control device is locked, the locking member 200 moves to the locking position, and the locking tongue 220 of the locking member 200 extends out of the locking hole 110 to achieve the locking of the locking control device. When the locking control device is unlocked, the locking member 200 moves to the unlocking position, and the locking tongue 220 of the locking member 200 retracts into the locking hole 110, thereby releasing the lock.

[0059] Please refer to Figure 6 and 7 In one embodiment, each locking member 200 has two locking tongues 220, and the two locking tongues 220 are located on the same side of the locking member 200. When the locking member 200 moves to the locking position, both of the two locking tongues 220 extend out of the locking hole 110. When the locking member 200 moves to the unlocking position, both of the two locking tongues 220 retract into the locking hole 110.

[0060] On the one hand, the two locking tongues 220 can span a relatively wide distance. When locking the host 800, they can also span a relatively wide locking distance, so that the host 800 can be locked to the bracket more firmly. On the other hand, the locking of the locking control device is achieved through a plurality of locking tongues 220, which improves the structural strength when the locking control device is locked. On the other hand, the synchronization of the movement of the plurality of locking tongues 220 on the locking member 200 is good, so that when the locking device is locked and unlocked, the plurality of locking tongues 220 can simultaneously extend into and withdraw from the corresponding locking holes 110.

[0061] Please refer to Figures 1-4 6 and 7, in one embodiment, the locking control device further includes a first elastic member 600. One end of the first elastic member 600 is connected to the base body 100, and the other end is connected to the locking member 200. The elastic restoring force of the first elastic member 600 is used to assist in driving the locking member 200 to stay in the locking position. The base body 100 has an abutting portion 180, and the abutting portion 180 is located on the rotation path when the switching member 300 drives the locking member 200 to move towards the locking position. When the locking member 200 is in the locking position, the elastic restoring force of the first elastic member 600 acting on the locking member 200 is sequentially transmitted to the switching member 300 through the rotating disc 421 and the first transmission member 410, so that the switching member 300 abuts tightly against the abutting portion 180.

[0062] Specifically, please refer to Figure 2 In the illustrated embodiment, when the locking member 200 is in the locking position, the first elastic member 600 exerts a force on the locking member 200 towards the unlocking position, that is, Figure 2 the F1 in Figure 2F2 in it, the acting force F2 makes the connecting part 320 press tightly against the abutting part 180. When the staff needs to move the locking part 200 to the unlocking position, it is necessary to overcome the acting force F2 to rotate the switch part 300 counterclockwise to achieve unlocking. Therefore, the first elastic part 600 plays a role in assisting the locking part 200 to stay in the locking position.

[0063] Please refer to Figure 3 and 6 , in an embodiment, the locking part 200 further includes a guiding groove 210, and the guiding groove 210 extends along the moving direction of the locking tongue 220. The base body 100 has a guiding post 120, and the guiding groove 210 is movably sleeved with the guiding post 120.

[0064] By the cooperation of the guiding groove 210 and the guiding post 120 to guide the moving direction of the locking part 200, the locking part 200 can only move linearly between the locking position and the unlocking position along the extending direction of the guiding groove 210, which is beneficial to improving the stability of the moving path of the locking part 200, and further beneficial to improving the reliability of the locking and unlocking actions of the lock control device. Of course, in other embodiments, the structure for guiding the locking part 200 is not limited to the guiding groove 210 and the guiding post 120. For example, the guiding structure can also be a guiding slide rail or a guiding rod.

[0065] Please refer to Figures 1-4 , 8 and 9, in an embodiment, the switch part 300 has a switch portion 310 and a connecting part 320, and the connecting part 320 is rotatably connected to the first transmission part 410. The switch portion 310 extends outside the side wall of the base body 100. When the base body 100 is connected between the bracket and the host 800, it can be unlocked by operating the switch portion 310 exposed outside the side wall. The side wall of the base body 100 has a switch groove 130, and the switch portion 310 is arranged in the switch groove 130. The switch part 300 can rotate relative to the base body 100 to make the switch portion 310 extend out of or retract into the switch groove 130.

[0066] Due to the addition of the switch groove 130, when the staff rotates the switch part 300 to make the switch portion 310 extend out of the switch groove 130, the switch part 300 drives the locking part 200 to move to the unlocking position, thereby realizing the unlocking of the lock control device. When the staff rotates the switch part 300 to make the switch portion 310 retract into the switch groove 130, the switch part 300 drives the locking part 200 to move to the locking position, thereby realizing the locking of the lock control device. That is, when the lock control device is locked, the switch part 300 will not protrude from the outer wall of the base body 100, thereby reducing the possibility that the staff accidentally touches the switch part 300 and causes the lock control device to be accidentally unlocked.

[0067] Please refer to Figure 8 and 9, in one embodiment, the locking control device further includes a cover body 700. The cover body 700 is movably connected to the base body 100, and the cover body 700 can move relative to the base body 100 to open and close the switch slot 130.

[0068] Due to the addition of the cover body 700, when it is necessary to unlock the locking control device, the staff needs to first rotate the cover body 700 to open the switch slot 130, and then rotate the switch part 310 in the switch slot 130 so that the switch part 310 extends out of the switch slot 130, thereby realizing the unlocking of the locking control device. After the locking control device is locked, the switch part 310 is located in the switch slot 130, and the staff can rotate the cover body 700 to close the switch slot 130 through the cover body 700. On the one hand, the switch part 310 in the switch slot 130 is protected by the cover body 700, thus preventing the staff from accidentally touching the switch member 300 before opening the cover body 700. On the other hand, after the cover body 700 closes the switch slot 130, there is no obvious convex or concave structure on the outer wall of the base body 100, thereby improving the flatness of the surface of the base body 100.

[0069] Please refer to Figure 8 and 9 , in one embodiment, the base body 100 has a positioning groove 140. The positioning groove 140 has an opening facing the cover body 700. A second elastic member 150 and a positioning ball head 160 are provided in the positioning groove 140. One end of the second elastic member 150 abuts against the inner wall of the positioning groove 140, and the other end abuts against the positioning ball head 160. The elastic restoring force of the second elastic member 150 is used to drive the positioning ball head 160 to move towards the opening of the positioning groove 140 so that a part of the positioning ball head 160 extends out of the opening of the positioning groove 140. The cover body 700 includes a rotating shaft portion 730. The outer peripheral surface of its rotating shaft portion 730 has a first clamping groove 710 and a second clamping groove 720 arranged at intervals. When the cover body 700 opens the switch slot 130, the first clamping groove 710 is clamped with the positioning ball head 160. When the cover body 700 closes the switch slot 130, the second clamping groove 720 is clamped with the positioning ball head 160.

[0070] When the staff rotates the cover body 700 to the position where the switch slot 130 is opened, the positioning ball head 160 is floatingly clamped with the first clamping groove 710, thereby positioning the cover body 700 at the position where the switch slot 130 is opened. When it is necessary to close the switch slot 130, the staff needs to overcome the acting force of the positioning ball head 160 on the first clamping groove 710 to drive the cover body 700 to rotate to the position where the switch slot 130 is closed. At this time, the positioning ball head 160 is floatingly clamped with the second clamping groove 720, thereby positioning the cover body 700 at the position where the switch slot 130 is closed. The cover body 700 can be positioned when it is located at the positions of opening and closing the switch slot 130, thereby preventing the cover body 700 from shaking under the action of external vibration or impact force.
