Referring to fig. 1 and 2, an embodiment of the present application provides a restraint device for connecting with a compartment of a transport vehicle to restrain an in-vehicle medical device 200 to the compartment of the transport vehicle (not shown).

The restraint device includes a first restraint assembly. With reference to fig. 1 to 4, the first constraint assembly comprises: a first constraint 110 and a second constraint 120. One end of the first restraint 110 is rotatably disposed in the cabin. The second restraint member 120 is movably connected to the other end of the first restraint member 110, so that the second restraint member 120 can be connected to the first mating portion 220 on the in-vehicle medical apparatus 200. When the second constraint piece 120 is connected to the first mating portion 220, the connection position of the second constraint piece 120 and the first mating portion 220 is not collinear with the rotation center of the first constraint piece 110 in the vertical direction and the horizontal direction, and the connection position of the second constraint piece 120 and the first mating portion 220 and the rotation center of the first constraint piece 110 are located on the same side of the first constraint piece 110 near the surface 113a of the first mating portion 220.

The in-vehicle medical apparatus 200 includes a main body 210 and a first fitting portion 220 connected to the main body 210. The in-vehicle medical apparatus 200 may be placed at a predetermined position on the compartment of the transportation vehicle by lifting or the like, and then the in-vehicle medical apparatus 200 may be restrained by the restraining means. When the in-vehicle medical apparatus 200 is placed at a predetermined position on the compartment of the transport vehicle, the second restraint member 120 is rotated with the first restraint member 110 to the position of the first fitting portion 220 on the in-vehicle medical apparatus 200 by rotating the first restraint member 110 relative to the compartment. The second restraint 120 is movable relative to the other end of the first restraint 110, so that the second restraint 120 can be connected with the first matching part 220 on the vehicle-mounted medical equipment 200, and the vehicle-mounted medical equipment 200 is restrained in the carriage, so that the operation is convenient.

In actual use, the end of the first restraint 110 that is connected to the cabin of the transporter is located below the end of the first restraint 110 that is connected to the second restraint 120. If the in-vehicle medical apparatus 200 receives an upward impact force during transportation by the transportation vehicle, the first restraint 110 receives an upward impact force F. Since the connection position of the second constraint member 120 and the first engagement portion 220 is not collinear with the rotation center of the first constraint member 110 in both the vertical direction and the horizontal direction when the second constraint member 120 is connected with the first engagement portion 220, and the connection position of the second constraint member 120 and the first engagement portion 220 and the rotation center of the first constraint member 110 are located on the same side of the first constraint member 110 near the surface 113a of the first engagement portion 220, the first constraint member 110 receives an upward impact force F to generate a moment M (see fig. 3) relative to the rotation center, and the moment M makes the first constraint member 110 press the first engagement portion 220, the second constraint member 120 is not easy to disengage from the first engagement portion 220, that is, the self-locking of the first constraint assembly and the first engagement portion 220 is realized, so that the engagement of the first constraint assembly and the first engagement portion 220 is more reliable, and the in-vehicle medical device 200 can be more reliably constrained on the carrier.

As shown in fig. 3, in one embodiment, the first constraint 110 comprises a tie rod 113, the tie rod 113 comprising a first segment 1131 and a second segment 1132 connected and angularly disposed. The second restraint 120 is movably coupled to an end of the first section 1131 remote from the second section 1132. The end of the second section 1132 remote from the first section 1131 is rotatably disposed in the cabin, and the rotation center of the second section 1132 is the rotation center of the first restraint member 110.

By having the first section 1131 and the second section 1132 disposed at an angle, it is convenient to make the rotation center of the second section 1132 (the rotation center of the first constraint member 110) and the connection position of the second constraint member 120 and the first engagement portion 220 be located on the same side of the first constraint member 110 near the face 113a of the first engagement portion 220 when the second constraint member 120 is connected with the first engagement portion 220, and it is convenient to make the connection position of the second constraint member 120 and the first engagement portion 220 not collinear with the rotation center of the first constraint member 110 in both the vertical direction and the horizontal direction.

In other embodiments, the connecting rod 113 may not be two sections disposed at an angle, and may be an arcuate rod, for example. One end of the arc-shaped rod is rotatably arranged in the carriage, the second constraint piece 120 is movably connected with the other end of the arc-shaped rod, so that when the second constraint piece 120 is connected with the first matching part 220, the rotation center of the first constraint piece 110 and the connection position of the second constraint piece 120 and the first matching part 220 are located on the same side of the first constraint piece 110, which is close to the surface 113a of the first matching part 220, and the connection position of the second constraint piece 120 and the first matching part 220 and the rotation center of the first constraint piece 110 are not collinear in the vertical direction and the horizontal direction.

Referring to fig. 1 to 4, in an embodiment, the second constraint member 120 includes a constraint body 121 and a limiting portion 122. The restraining body 121 is movably connected to the first restraining element 110, and the limiting portion 122 is a protruding structure circumferentially disposed at one end of the restraining body 121, so that the second restraining element 120 can pass through the through hole 201 of the first matching portion 220 on the medical device 200 at a specific angle. Therefore, the stopper 122 cannot pass through the first engaging portion 220 at angles other than the specific angle. Since the constraint body 121 is movably connected to the first constraint member 110, the angle of the limiting portion 122 can be switched between the specific angle and the other angle by rotating the constraint body 121 relative to the first constraint member 110.

Referring to fig. 3 and 4, the first mating portion 220 has a first surface 221 and a second surface 222 disposed opposite to each other. The through hole 201 penetrates the first surface 221 and the second surface 222.

When the in-vehicle medical apparatus 200 is placed at a predetermined position on the compartment of the transport vehicle, the first restraint 110 is rotated relative to the compartment, so that the second restraint 120 rotates with the first restraint 110 to the position of the first mating portion 220 on the in-vehicle medical apparatus 200, and at this time, the limiting portion 122 is opposite to the first surface 221 and corresponds to the position of the through hole 201. By rotating the constraint body 121 relative to the first constraint member 110 and adjusting the limiting portion 122 to a specific angle, the limiting portion 122 can pass through the through hole 201. Therefore, the limiting portion 122 may be moved to a side of the second surface 222 of the first fitting portion 220 facing away from the first surface 221 by moving the constraining body 121 such that the limiting portion 122 passes through the through hole 201 of the first fitting portion 220, i.e., the state shown in fig. 10. At this time, as shown in fig. 11, the constraining body 121 is rotated with respect to the first constraining member 110 to adjust the limiting part 122 to other angles than the specific angle, and the limiting part 122 cannot pass through the through hole 201 so that the limiting part 122 is blocked by the second surface 222 (see fig. 4 and 12). So far, the restraint of the vehicle-mounted medical equipment 200 is realized through the cooperation of the first restraint component and the first cooperation part 220, and the operation process acts continuously, and is simple and convenient.

When the in-vehicle medical apparatus 200 is transported to the use place by the transport vehicle, the engagement of the first restraint assembly with the first engagement portion 220 may be released to unload the in-vehicle medical apparatus 200. The process of releasing the engagement of the first restraint assembly with the first engagement portion 220 is as follows: by rotating the constraint body 121 to adjust the limiting portion 122 to a specific angle, and then moving the constraint body 121 to move the limiting portion 122 toward the through hole 201 until the limiting portion passes through the through hole 201, the limiting portion 122 moves to a side of the first surface 221 away from the second surface 222. To this end, the engagement of the first restraint assembly with the first engagement portion 220 is released.

Referring to fig. 3 and 4, in an embodiment, the restraining device further includes an elastic member 130, and the first restraining member 110 is movably connected with the restraining body 121 through the elastic member 130, so that the restraining body 121 and the first restraining member 110 can move relatively through elastic deformation of the elastic member 130. The elastic member 130 is configured to drive the constraining body 121 to move so that the limiting portion 122 abuts against the first mating portion 220.

When the limiting portion 122 is adjusted to a specific angle, the limiting body 121 can be moved to overcome the resistance of the elastic member 130, so that the limiting portion 122 passes through the through hole 201 of the first mating portion 220, and the limiting portion 122 moves to a side of the second surface 222 of the first mating portion 220 facing away from the first surface 221, i.e. the state shown in fig. 10. At this time, as shown in fig. 11, the second constraint member 120 is rotated with respect to the first constraint member 110 again to adjust the limit portion 122 to an angle other than the specific angle, and then the constraint body 121 is released, so that the elastic restoring force of the elastic member 130 drives the constraint body 121 to move the limit portion 122 toward the second surface 222 until abutting against the second surface 222 (see fig. 4 and 12), and thus the limit portion 122 is blocked by the second surface 222.

Because the elastic restoring force of the elastic member 130 makes the limiting portion 122 abut against the second surface 222 of the first matching portion 220, the constraint body 121 is connected with the first constraint member 110 through the elastic member 130, and the first constraint member 110 is connected with the carriage of the transport vehicle, so as to implement constraint on the first matching portion 220, namely implement constraint on the medical equipment 200, and further reduce vibration and displacement of the medical equipment 200 in the transported process. Moreover, the stopper 122 is abutted against the second surface 222 of the first fitting portion 220 by the elastic restoring force of the elastic member 130, so that the first restraint assembly can be reliably fitted to the first fitting portion 220 even if the in-vehicle medical apparatus 200 is impacted during transportation.

The process of releasing the engagement of the first restraint assembly with the first engagement portion 220 is as follows: the stopper 122 is separated from the second surface 222 by moving the constraint body 121 to overcome the resistance of the elastic member 130. Then, the second constraint member 120 is rotated to adjust the limiting portion 122 to a specific angle, and then the constraint body 121 is released, so that the elastic restoring force of the elastic member 130 drives the constraint body 121 to move, so that the limiting portion 122 moves toward the through hole 201 until penetrating out of the through hole 201, and then the limiting portion 122 moves to a side of the first surface 221 facing away from the second surface 222. To this end, the engagement of the first restraint assembly with the first engagement portion 220 is released.

Referring to fig. 3 and 4, in one embodiment, the first restraint member 110 has a circular guide cavity 101, and the restraint body 121 has at least a partial cylindrical section penetrating the circular guide cavity 101.

One end of the constraint body 121 connected to the limiting portion 122 extends out of the circular guide cavity 101, so that the limiting portion 122 can pass through the through hole 201 when moving along with the constraint body 121. Since the cylindrical section of the constraining body 121 is disposed through the circular guide cavity 101, the circular guide cavity 101 defines the moving direction of the constraining body 121 along the extending direction of the circular guide cavity 101, so that the moving direction of the second constraining member 120 can be stabilized, and the limiting portion 122 can be ensured to pass through the through hole 201 at a specific angle.

Since the circular guide cavity 101 defines the movement direction of the constraining body 121 along the extending direction of the circular guide cavity 101, it can be understood that when the first constraining component is matched with the first matching portion 220 to constrain the on-vehicle medical device 200, the extending direction of the circular guide cavity 101 is the same as the penetrating direction of the through hole 201, so that the limiting portion 122 moves along with the constraining body 121 along the extending direction of the circular guide cavity 101 together, the limiting portion 122 can pass through the through hole 201, and the limiting portion 122 can abut against the second surface 222.

In the present embodiment, when the in-vehicle medical apparatus 200 is placed at a predetermined position on the cabin of the transportation vehicle, the first surface 221 and the second surface 222 are disposed opposite to each other in the front-rear direction of the in-vehicle medical apparatus 200, and the through hole 201 penetrates in the front-rear direction of the in-vehicle medical apparatus 200. That is, when the first restraining member is engaged with the first engaging portion 220 to restrain the in-vehicle medical apparatus 200 during transportation of the in-vehicle medical apparatus 200 by the transportation vehicle, the extending direction of the circular guide chamber 101 is the same as the penetrating direction of the through hole 201, both along the front-rear direction of the in-vehicle medical apparatus 200.

During transportation of the in-vehicle medical apparatus 200 by the transportation vehicle, since the first restraint 110 is connected to the vehicle compartment, the circular guide chamber 101 defines the direction of movement of the restraint body 121 along the extending direction of the circular guide chamber 101 (i.e., the penetrating direction of the through hole 201). Because the limiting portion 122 passes through the through hole 201 and abuts against the second surface 222, and the limiting portion 122 is connected to one end of the restraining body 121, the restraining body 121 is penetrated in the through hole 201, so that the restraining body 121 can limit or prevent the vehicle-mounted medical device 200 from moving upwards relative to the carriage, and further the possibility that the vehicle-mounted medical device 200 bounces from the bottom of the carriage due to jolt in the process of being transported is reduced, namely the possibility that the vehicle-mounted medical device 200 is separated from the bottom of the carriage is reduced.

Referring to fig. 4, in one embodiment, the circular guide chamber 101 includes a first circular chamber 1011 and a second circular chamber 1012 which are in communication and coaxially disposed. The inner diameter of the first circular cavity 1011 is larger than the inner diameter of the second circular cavity 1012 such that the junction of the side wall of the first circular cavity 1011 and the side wall of the second circular cavity 1012 forms a first stepped surface 101a.

The cylindrical section of the restraining body 121 includes a first section 1211 and a second section 1212 that are connected and coaxially disposed. The diameter of the first segment 1211 is greater than the diameter of the second segment 1212 such that the junction of the side of the first segment 1211 with the side of the second segment 1212 forms the second step 121a. The end of the second segment 1212 facing away from the first segment 1211 is connected to the stop 122.

The first segment 1211 is disposed through the first circular cavity 1011, and the second segment 1212 is disposed through the second circular cavity 1012, so that the second step surface 121a is opposite to the first step surface 101a and is blocked by the first step surface 101a, thereby preventing the first segment 1211 from moving out of the circular guide cavity 101 from the second circular cavity 1012, and effectively ensuring the reliable connection between the constraint body 121 and the first constraint member 110.

Referring to fig. 3 and 4, in an embodiment, the elastic member 130 is sleeved on the constraint body 121 and is located in the circular guide cavity 101; the side of the constraint body 121 is provided with a protruding portion 123, and two ends of the elastic member 130 are respectively abutted against the protruding portion 123 and the cavity wall of the circular guide cavity 101.

In assembly, the elastic member 130 may be first installed in the circular guide cavity 101, and then the constraint body 121 is inserted into the elastic member 130, so that the protrusion 123 and the cavity wall of the circular guide cavity 101 can respectively abut against the elastic member 130.

Referring to fig. 4, in an embodiment, the elastic member 130 is sleeved on the first segment 1211, that is, the elastic member 130 is located in the first circular cavity 1011. It will be appreciated that the first stepped surface 101a is one cavity wall of the first circular cavity 1011. One end of the elastic member 130 abuts against the protruding portion 123, and the other end abuts against the first stepped surface 101a, so that the constraint body 121 and the first constraint member 110 are movably connected through the elastic member 130.

Referring to fig. 3 and 4, in an embodiment, the first restraint 110 includes a guide 111 and a limiting plate 112. The circular guide chamber 101 is provided in the guide 111. The guide 111 has an opening (not shown) communicating with the circular guide chamber 101. The limiting plate 112 is connected to the guide 111 and located at the opening. The limiting plate 112 is located at a side of the protrusion 123 facing away from the elastic member 130 and blocks the protrusion 123.

Specifically, since the guide 111 has an opening communicating with the circular guide chamber 101, the elastic member 130 can be fitted into the circular guide chamber 101 through the opening, and the constraining body 121 can be fitted into the circular guide chamber 101 through the opening, so that the elastic member 130 abuts between the chamber wall of the circular guide chamber 101 and the projection 123. Through connecting limiting plate 112 in guide 111 and being located this opening part, and limiting plate 112 is located the one side that bulge 123 deviates from elastic component 130 to limiting plate 112 can block bulge 123, prevents bulge 123 to shift out circular guide chamber 101, and then can guarantee the reliable connection of restraint body 121, elastic component 130 and first restraint 110.

Referring to fig. 3 to 4, in an embodiment, an end of the constraint body 121 facing away from the limiting portion 122 extends out of the circular guide cavity 101. When in operation, the restraint body 121 can be held by hand to deviate from one end of the limit part 122 so as to rotate the restraint body 121, thereby facilitating the rotation of the limit part 122.

Specifically, in the present embodiment, an end of the constraining body 121 facing away from the limiting portion 122 may protrude from the circular guide cavity 101 through the limiting plate 112.

Referring to fig. 3 to 6, in an embodiment, a knob 124 is disposed at an end of the constraint body 121 facing away from the limiting portion 122, and the second constraint member 120 is integrally rotated by operating the knob 124, so as to facilitate adjusting an angle of the limiting portion 122.

As shown in fig. 1, 2 and 14, in an embodiment, the restraining device further includes a positioning structure 140, where the positioning structure 140 is configured to be disposed on the carriage, and the positioning structure 140 has a first positioning groove 102, and the first positioning groove 102 is configured to cooperate with a moving wheel of the in-vehicle medical apparatus 200.

Specifically, when the in-vehicle medical apparatus 200 is placed in the compartment of the transport vehicle by lifting or the like, the moving wheel 230 of the in-vehicle medical apparatus 200 may be placed in the first positioning groove 102, so that the in-vehicle medical apparatus 200 may be positioned such that the in-vehicle medical apparatus 200 is accurately positioned at the predetermined position described in any of the foregoing embodiments. That is, the moving wheel 230 of the in-vehicle medical apparatus 200 is located in the first positioning groove 102 when the in-vehicle medical apparatus 200 is at a predetermined position on the cabin of the transportation vehicle.

Further, as described above, when the on-vehicle medical device 200 is transported by the transport vehicle, the first constraint component is matched with the first matching portion 220 to constrain the on-vehicle medical device 200, the extending direction of the circular guiding cavity 101 is the same as the penetrating direction of the through hole 201, and the constraint body 121 is simultaneously inserted into the circular guiding cavity 101 and the through hole 201, so that the constraint body 121 defines that the extending direction of the circular guiding cavity 101 is the same as the penetrating direction of the through hole 201, and further defines that the first constraint element 110 cannot rotate relative to the carriage, and then defines that the height position of the second constraint element 120 in the vertical direction is unchanged. In this manner, the second restraint 120 can limit or prevent the vehicle-mounted medical device 200 from moving upward relative to the carriage, so that the moving wheel 230 of the vehicle-mounted medical device 200 can be limited or prevented from moving to a higher position outside the first positioning groove 102, and further, the moving wheel 230 of the vehicle-mounted medical device 200 can be limited or prevented from moving in a direction of moving out of the first positioning groove 102, so that the vehicle-mounted medical device 200 can be reliably positioned.

As shown in fig. 1, in an embodiment, the extension direction of the first positioning groove 102 is along the axial direction of the moving wheel 230, and the width direction of the first positioning groove 102 is the advancing and retreating directions of the moving wheel 230. Therefore, in the present embodiment, the second restraining member 120 can restrict or prevent the moving wheel 230 of the in-vehicle medical apparatus 200 from moving to a higher position outside the first positioning groove 102 in the forward or backward direction during the transportation of the in-vehicle medical apparatus 200 by the transportation vehicle.

In one embodiment, the groove walls of the first positioning groove 102 are curved, so that the moving wheel 230 can roll along the curved surface, thereby moving into or out of the first positioning groove 102.

As shown in fig. 1, in an embodiment, the restraint device further includes a storage box 150, the storage box 150 is disposed in a carriage, one end of the first restraint member 110 is rotatably disposed in the storage box 150, the storage box 150 is provided with an avoidance opening 103, and the avoidance opening 103 is used for enabling the first restraint member 110 and the second restraint member 120 to rotate into or out of the storage box 150.

Specifically, by rotating the first restraint member 110, the first restraint member 110 and the second restraint member 120 are caused to pass through the avoidance port 103 and turn into the storage box 150, so that the first restraint assembly can be prevented from interfering with or unloading from a predetermined position of the in-vehicle medical apparatus 200 placed on the vehicle cabin as much as possible. When the first restraint assembly is required to be matched with the first matching part 220 to restrain the vehicle-mounted medical equipment 200, the first restraint 110 and the second restraint 120 can pass through the avoidance opening 103 through rotation of the first restraint 110, and the storage box 150 can be rotated out, so that the first restraint assembly can restrain the vehicle-mounted medical equipment 200 conveniently.

As shown in fig. 1, in an embodiment, when the first restraint member 110 and the second restraint member 120 rotate out of the storage box 150 through the avoidance opening 103, the first restraint member 110 is in clearance fit with the avoidance opening 103 in the rotation axis direction of the first restraint member 110, so that the first restraint member 110 can adjust the position of the first restraint member 110 relative to the storage box 150 in the rotation axis direction of the first restraint member 110. By adjusting the position of the first constraint member 110 in the rotation axis direction of the first constraint member 110, the second constraint member 120 can be carried in the direction to adjust the position, so that the position of the limiting portion 122 corresponds to the position of the through hole 201, and the limiting portion 122 can smoothly pass through the through hole 201.

In an embodiment, the first restraint member 110 may be sleeved on the rotating shaft 151, and the first restraint member 110 may be movably matched with the rotating shaft 151, so as to realize that the position of the first restraint member 110 may be adjusted relative to the storage box 150 in the direction of the rotation axis of the first restraint member 110.

As shown in fig. 2 and 13, in an embodiment, the restraint device further includes a second restraint assembly including at least a first blocking portion 160, the first blocking portion 160 being coupled to the vehicle cabin. The first restraint assembly is configured to cooperate with one end of the in-vehicle medical apparatus 200 in the front-rear direction, and the first blocking portion 160 is configured to cooperate with the other end of the in-vehicle medical apparatus 200 in the front-rear direction, so that the in-vehicle medical apparatus 200 is fixed to the vehicle cabin in a limited manner.

Specifically, in the present embodiment, the first restraint assembly is for cooperation with the rear end of the in-vehicle medical apparatus 200 in the front-rear direction. The first blocking portion 160 is for engaging with the front end of the in-vehicle medical apparatus 200 in the front-rear direction, i.e., for blocking the forward displacement of the in-vehicle medical apparatus 200.

In other embodiments, the first restraint assembly may be engaged with the front end of the in-vehicle medical device 200 in the front-to-rear direction. The first blocking portion 160 is for engaging with the rear end of the in-vehicle medical apparatus 200 in the front-rear direction, i.e., for blocking rearward displacement of the in-vehicle medical apparatus 200.

In an embodiment, the restraining means comprises at least one set of first restraining components. As shown in fig. 1, in the present embodiment, the number of first constraint components is two.

In other embodiments, the number of first constraining components may also be a set. The number of first restraint components may also be greater than two, such as three, four, etc.

As shown in fig. 13, in an embodiment, the second restraint assembly further includes a buffer 161. The buffer portion 161 is, for example, an elastic pad, an air bag, or the like. The buffer portion 161 is connected to the first blocking portion 160 and is located at a side of the first blocking portion 160 near the on-vehicle medical device 200, so that the buffer portion 161 can buffer an impact force between the first blocking portion 160 and the on-vehicle medical device 200 during the transportation process of the on-vehicle medical device 200, and further reduce damage to the on-vehicle medical device 200.

As shown in fig. 13, in one embodiment, the second restraint assembly further includes a second stop 170. The second blocking portion 170 is connected to the first blocking portion 160, and the second blocking portion 170 is configured to block the movement of the in-vehicle medical device 200 in a direction away from the bottom of the vehicle cabin.

Specifically, the in-vehicle medical apparatus 200 further includes a second fitting portion 240. When the in-vehicle medical device 200 is placed at a predetermined position on the cabin of the transportation vehicle, the second blocking portion 170 is located above the second fitting portion 240, so that the second fitting portion 240 can be blocked from being displaced upward relative to the cabin, and thus the possibility that the in-vehicle medical device 200 is sprung from the cabin bottom of the cabin due to jolt during transportation, i.e., the possibility that the in-vehicle medical device 200 is separated from the cabin bottom of the cabin is reduced.

As shown in fig. 13, in an embodiment, the second engaging portion 240 is a roller 240. The second blocking portion 170 is configured to be in rolling engagement with the roller 240, so that when the in-vehicle medical device 200 is moved to or removed from a predetermined position on the vehicle compartment to be unloaded from the vehicle compartment, frictional resistance therebetween can be reduced by the rolling engagement of the second blocking portion 170 with the roller 240, thereby facilitating smooth movement of the in-vehicle medical device 200.

In an embodiment, the second blocking portion 170 and the first blocking portion 160 may be integrally formed.

In one embodiment, the restraining device further comprises a guide structure. The guide structure is for being provided on the carriage and guiding the moving direction of the in-vehicle medical apparatus 200.

When the in-vehicle medical apparatus 200 is placed on the compartment of the transport vehicle by lifting or the like, the moving direction of the in-vehicle medical apparatus 200 can be guided by the guide structure, so that centering in the left-right direction can be achieved when the in-vehicle medical apparatus 200 moves to a predetermined position under the guidance of the guide structure.

Further, when the in-vehicle medical apparatus 200 moves to the position where the first blocking portion 160 is located under the guidance of the guide structure, the restraint of neutralizing the position where the first blocking portion 160 is located is completed at the same time.

As shown in fig. 14, in an embodiment, the guide structure includes a first guide rail 181 and a second guide rail 182 disposed at a spacing, and a movement space 104 of the in-vehicle medical apparatus 200 is limited between the first guide rail 181 and the second guide rail 182.

Specifically, when the in-vehicle medical apparatus 200 is placed on the compartment of the transport vehicle by lifting or the like, the in-vehicle medical apparatus 200 may be placed in the moving space 104 and the in-vehicle medical apparatus 200 may be moved along the moving space 104, thereby facilitating accurate and rapid movement of the in-vehicle medical apparatus 200 to a predetermined position.

As shown in fig. 14, in an embodiment, the distance between the first rail 181 and the second rail 182 gradually decreases in the advancing direction of the in-vehicle medical apparatus 200. That is, when the in-vehicle medical apparatus 200 enters between the first rail 181 and the second rail 182, the space between the first rail 181 and the second rail 182 is large, thereby facilitating the in-vehicle medical apparatus 200 to enter the movement space 104. As the in-vehicle medical apparatus 200 advances, the distance between the first rail 181 and the second rail 182 gradually decreases, so that the position of the in-vehicle medical apparatus 200 in the left-right direction can be gradually defined, i.e., centering of the in-vehicle medical apparatus 200 in the left-right direction is facilitated.

Specifically, as shown in fig. 14, the surfaces of the first rail 181 and the second rail 182 opposite to each other are inclined to each other such that the space between the first rail 181 and the second rail 182 is gradually reduced.

In one embodiment, the guide structure is positioned in front of the positioning structure 140 along the forward direction of the in-vehicle medical apparatus 200. Accordingly, when the guide structure guides the movement of the in-vehicle medical apparatus 200, the front wheel 232 of the guide movement wheel 230 moves. When the rear wheel 231 of the moving wheel 230 is engaged with the first positioning groove 102 in the process that the front wheel 232 moves under the guide of the guide structure, at this time, the first positioning groove 102 plays a role of reminding the user of the position.

In other embodiments, it is also possible that the front wheel 232 of the moving wheel 230 mates with the first detent 102.

An embodiment of the present application further provides a vehicle cabin, wherein the bottom surface of the vehicle cabin is provided with the restraint device of any one of the above, and the restraint device is used for fixing the vehicle-mounted medical equipment 200 on the bottom surface of the vehicle cabin.

An embodiment of the present application further provides a vehicle-mounted medical device 200, including a main body 210 and a first mating portion 220 connected with the main body 210, where the first mating portion 220 is provided with a through hole 201, and the through hole 201 is used for allowing the limiting portion 122 to pass through at a specific angle.

Referring to fig. 7, in an embodiment, the through hole 201 has at least one extending hole 2011 in a radial direction. In the present embodiment, there are two extension holes 2011, and the two extension holes 2011 extend in directions away from each other, respectively.

Referring to fig. 5, 7 and 9, when the limiting portion 122 is at a specific angle, the limiting portion 122 corresponds to the position of the corresponding extension hole 2011, so that the limiting portion 122 can pass through the corresponding extension hole 2011.

Referring to fig. 6, 7, 8, and 11, when the stopper 122 is at an angle other than the specific angle, the stopper 122 is displaced from the corresponding extension hole 2011, and the stopper 122 cannot pass through the through hole 201.

It will be appreciated that in other embodiments, the protruding form of the limiting portion 122 is not limited to that shown in fig. 5 and 6, nor is the shape of the through hole 201 limited to that shown in fig. 7, as long as it is achieved that the through hole 201 allows the limiting portion 122 to pass through at a specific angle, and the limiting portion 122 cannot pass through the through hole 201 at angles other than the specific angle.

In one embodiment, the first mating portion 220 is a tail board of the in-vehicle medical apparatus 200.

Of course, in other embodiments, the first engaging portion 220 may be configured separately and the first engaging portion 220 may be connected to the main body 210.

Referring to fig. 8 to 12, in an embodiment, a second positioning groove 202 is formed on the second surface 222, the second positioning groove 202 is used for positioning and matching with the limiting portion 122, and a groove bottom of the second positioning groove 202 is used for abutting against the limiting portion 122. When the elastic restoring force of the elastic member 130 drives the constraint body 121 to move so that the limiting portion 122 moves towards the second surface 222, that is, moves towards the second positioning groove 202, until the limiting portion 122 abuts against the groove bottom of the second positioning groove 202. The second positioning groove 202 is in positioning fit with the limiting portion 122, so that the limiting portion 122 is more reliably matched with the first matching portion 220.

Referring to fig. 13, in an embodiment, the in-vehicle medical apparatus 200 includes a second mating portion 240 disposed on the main body 210.

Referring to fig. 13, in an embodiment, the second engaging portion 240 is a roller 240 for rolling engagement with the second blocking portion 170.

When the restraint device, the carriage and the vehicle-mounted medical equipment are placed at the preset position on the carriage of the transport vehicle, the first restraint member 110 is rotated relative to the carriage, so that the second restraint member 120 rotates along with the first restraint member 110 to the position where the first matching portion 220 on the vehicle-mounted medical equipment 200 is located. The second restraint 120 is connected with the first matching part 220 on the vehicle-mounted medical equipment 200, so that the vehicle-mounted medical equipment 200 is restrained in the carriage, and the operation is convenient. If the in-vehicle medical apparatus 200 receives an upward impact force during transportation by the transportation vehicle, the first restraint 110 receives an upward impact force F. Since the connection position of the second constraint member 120 and the first engagement portion 220 is not collinear with the rotation center of the first constraint member 110 in both the vertical direction and the horizontal direction when the second constraint member 120 is connected with the first engagement portion 220, and the connection position of the second constraint member 120 and the first engagement portion 220 and the rotation center of the first constraint member 110 are located on the same side of the first constraint member 110 near the surface 113a of the first engagement portion 220, the first constraint member 110 receives an upward impact force F to generate a moment M (see fig. 3) relative to the rotation center, and the moment M makes the first constraint member 110 press the first engagement portion 220, the second constraint member 120 is not easy to disengage from the first engagement portion 220, that is, the self-locking of the first constraint assembly and the first engagement portion 220 is realized, so that the engagement of the first constraint assembly and the first engagement portion 220 is more reliable, and the in-vehicle medical device 200 can be more reliably constrained on the carrier.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
