Example two
Based on the quick release assembly 24, the support column 3, the movable sleeve 5 and the locking screw 6 proposed in the first embodiment, the present invention provides a further technical solution as shown in fig. 2 to 9.
The quick release assembly 24 comprises a ring sleeve 241 sleeved at one end of the shaft rod 22 and two sets of limiting grooves 242 arranged outside the shaft rod 22, the cross section of each limiting groove 242 is J-shaped, two sets of inserted rods 243 corresponding to the limiting grooves 242 are arranged on the inner side of the ring sleeve 241, an annular groove 244 is formed in one side of the ring sleeve 241, a movable ring 245 is movably connected inside the annular groove 244, a plurality of stepped holes 246 are annularly formed in one side, away from the ring sleeve 241, of the movable ring 245, a connecting screw 247 is arranged inside the stepped hole 246, the connecting screw 247 is slidably connected with the stepped hole 246, the connecting screw 247 is in threaded connection with the ring sleeve 241, a first spring 248 is arranged outside the connecting screw 247, and the first spring 248 is arranged inside the annular groove 244.
The cross section of the limiting groove 242 is formed in a J shape, the ring sleeve 241 is sleeved on the shaft rod 22 from one end of the shaft rod 22, the inserting rod 243 on the inner side of the ring sleeve 241 slides into the limiting groove 242 along the limiting groove 242, then the inserting rod 243 can slide to the innermost end of the limiting groove along the J-shaped limiting groove 242 by rotating the ring sleeve 241, so that the situation that the ring sleeve 241 directly slides out along the shaft rod 22 in the using process is avoided, the movable ring 245 is arranged on one side of the ring sleeve 241, the movable ring 245 can move along the axial direction of the ring sleeve 241, and the moving stroke of the movable ring 245 can be limited through the matching of the connecting screw 247 and the stepped hole 246;
when the device is used, the T-shaped shaft 22 penetrates through the two shaft seats 21 to enable the insertion rod 243 to be aligned with the limiting groove 242, then the ring sleeve 241 is sleeved on the shaft 22 from the other side of the shaft seat 21 to enable the movable ring 245 on one side of the ring sleeve 241 to abut against the shaft seat 21, then the ring sleeve 241 is continuously moved to enable the movable ring 245 to contract towards the inner part of the annular groove 244 on one side of the ring sleeve 241 and compress the first spring 248, then the ring sleeve 241 is rotated to enable the ring sleeve 241 to drive the insertion rod 243 to slide along the J-shaped limiting groove 242, finally the ring sleeve 241 is loosened, under the action of the first spring 248, the movable ring 245 is far away from the ring sleeve 241, the movable ring 245 is blocked by the shaft seats 21, the ring sleeve 241 drives the insertion rod to move to the tail end of the limiting groove 242, at the moment, the insertion rod 243 is limited at the tail end of the limiting groove 242, and in the using process of the device, force towards the shaft 21 cannot be provided for the insertion rod 243, therefore, the ring sleeve 241 cannot be separated from the shaft 22 when the shaft seat 22 is used, and the shaft 23 can be limited in the connecting hole 23.
The cross-sectional shape of support column 3 sets up to T shape, the both ends of support column 3 respectively with two adjacent first aid splint 1 back movable sleeve 5 corresponding, support column 3 one end is provided with removable stop screw 9.
Through setting up support column 3 into the T shape, and set up detachable stop screw 9 at its one end, can set up the hindrance at the both ends of support column 3, 3 roll-off movable sleeve 5's of support column inside when avoiding using, and detachable stop screw 9 can pull down when necessary to the convenience takes out support column 3.
The movable sleeve 5 comprises a square tubular shell 51, rotating shafts 52 communicated with the shell 51 are arranged on two sides of the shell 51 in a mirror image mode, the rotating shafts 52 are hollow cylindrical, and the rotating shafts 52 are rotatably connected with the support frame 4;
the square tubular casing 51 and the support column 3 looks adaptation can avoid the support column 3 to take place to rotate when using, and then has avoided stop screw 9 to send circumferential direction rather than and lead to stop screw 9 to drop to the design of the pivot 52 that hollow and be linked together with casing 51 can make casing 51 rotate around support frame 4, and can not obstruct locking screw 6 and carry out spacing fixed to the inside support column 3 of casing 51.
The shape of the locking screw 6 is stepped, the thick outer circular surface of the locking screw 6 is provided with threads and is in threaded connection with the support frame 4, the thin outer circular surface of the locking screw 6 is smaller than the inner diameter of the rotating shaft 52 and is concentrically arranged with the rotating shaft 52, and one end of the locking screw 6 is in contact with the support column 3 inside the shell 51.
Locking screw 6 and 4 threaded connection of support frame, when can guaranteeing to rotate locking screw 6, make locking screw 6 along its axial displacement, and the one end of locking screw 6 runs through pivot 52, and contact with the inside support column 3 of casing 51, support tight support column 3 through locking screw 6, lock support column 3, accomplish the locking to the inside support column 3 of casing 51 through rotating locking screw 6, be connected support column 3 and the support frame 4 at first aid splint 1 back, and then lock adjacent first aid splint 1, accomplish the shape locking of first aid splint 1.
The implementation mode is specifically as follows: the detachable emergency treatment device is a detachable structure, when the detachable emergency treatment device is used, the locking screw 6 is firstly loosened, the connection between the locking screw 6 and the supporting column 3 is released, the supporting column 3 can move in the shell 51, then the limiting screw 9 at one end of the supporting column 3 is disassembled, the supporting column 3 can be drawn out from the shell 51, meanwhile, the locking of one end of the shaft rod 22 is released through the quick-release assembly 24, the shaft rod 22 can be drawn out, the connection between the two groups of shaft seats 21 is released, at the moment, all the connection between the adjacent emergency treatment splints 2 is lost, the disassembly and assembly can be carried out at will, the adjustment can be carried out according to the size of an affected part of a wounded person, in addition, two groups of shaft seats 21 can be independently formed at two ends of the device after the assembly, the two groups of shaft seats 21 can be fixedly connected with a stretcher or a stretcher bed for transporting the wounded person through the connecting holes 23 on the shaft seats 21, and the secondary injury to the wounded person during the transportation process is avoided.
