Referring to fig. 1-9, the present utility model provides a double wheelchair connecting device, which is used for connecting between a front wheelchair 100 and a rear wheelchair 100, when in use, a worker stands between the two wheelchairs 100, and drives the rear wheelchair 100 to synchronously move under the action of the connecting device of the present utility model by controlling the movement of the front wheelchair 100, so as to realize a 'one-to-two' service. The double wheelchair connecting device comprises a bending assembly 1, a front connecting pipe 2, a rear connecting pipe 3, a front connecting part 4 connected with a front wheelchair 100 and a rear connecting part 5 connected with a rear wheelchair 100, wherein the bending assembly 1 comprises a first bending part 11, a second bending part 12 and a locking structure 13, the first bending part 11 is rotatably connected with the second bending part 12, the locking structure 13 is used for locking the first bending part 11 and the second bending part 12 so that the first bending part 11 and the second bending part 12 are relatively fixed, two ends of the front connecting pipe 2 are respectively fixedly connected with the front connecting part 4 and the first bending part 11, and two ends of the rear connecting pipe 3 are respectively fixedly connected with the rear connecting part 5 and the second bending part 12.

When the front connecting pipe 2 and the rear connecting pipe 3 are installed, the second bending piece 12 is rotated relative to the first bending piece 11, so that the front connecting pipe 2 and the rear connecting pipe 3 are adjusted to be in a straight state, and the first bending piece 11 and the second bending piece 12 are locked through the locking structure 13. Then, the front connection pipe 2 is fixedly installed at the rear end of the front wheelchair 100 through the front connection member 4, and the rear connection pipe 3 is fixedly installed at the front end of the rear wheelchair 100 through the rear connection member 5, and at this time, the front and rear wheelchairs 100 are fixedly connected together. When in use, a worker stands behind the front wheelchair 100, and when pushing the front wheelchair 100, the rear wheelchair 100 synchronously moves under the drive of the front wheelchair 100, so that two people with inconvenient legs and feet can be transferred each time, and the 'one-to-two' service is realized. In addition, in order to improve stability, two double wheelchair connection devices of the present utility model are connected between the front and rear wheelchairs 100.

Referring to fig. 7-9, a U-shaped groove 111 is formed in the first bending member 11, a pin shaft 112 is fixedly connected between two opposite side walls of the U-shaped groove 111, the second bending member 12 has a block structure matched with the U-shaped groove 111, a rotating sleeve 121 is fixedly arranged on the second bending member 12, and the rotating sleeve 121 is rotatably sleeved outside the pin shaft 112, so that a rotation relationship between the first bending member 11 and the second bending member 12 is realized. When the second bending piece 12 is rotated relative to the first bending piece 11, the second bending piece 12 can be gradually accommodated in the U-shaped groove 111, or the second bending piece 12 can be gradually moved out of the U-shaped groove 111, and when the second bending piece 12 is accommodated in the U-shaped groove 111, the locking structure 13 can lock the first bending piece 11 and the second bending piece 12, and at the moment, the first bending piece and the second bending piece tend to be in a straight state.

In this embodiment, the bottom of the first bending member 11 is provided with a through hole 113, the second bending member 12 is provided with a through hole 122, the locking structure 13 includes a locking pin 131, a plug 132 is mounted at the upper end of the locking pin 131, and the lower end of the locking pin 131 is slidably mounted in the through hole 122 and passes through the through hole 113. When the locking pin 131 passes through the through hole 122 and the through hole 113 at the same time, the second bending piece 12 cannot rotate relative to the first bending piece 11, and at this time, the two are in a locking state; when the locking pin 131 is moved upward to be separated from the through hole 113, at this time, the second bending member 12 can be rotated relative to the first bending member 11, and at this time, both are in an unlocked state, and by rotating, the angle between the front connection pipe 2 and the rear connection pipe 3 can be reduced, thereby facilitating folding and storage. In addition, the stopper 132 is a nut, and the stopper 132 prevents the locking pin 131 from passing through the second bending member 12 from top to bottom, thereby preventing the locking pin 131 from falling.

The bottom of the second bending member 12 is provided with a containing groove 123 communicated with the through hole 122, the lower end of the locking pin 131 is convexly provided with a supporting edge 1311, the locking structure 13 further comprises an elastic member 133, the elastic member 133 is contained in the containing groove 123, the upper end of the elastic member 133 is supported against the bottom wall of the containing groove 123, the lower end of the elastic member 133 is supported against the supporting edge 1311, so that the locking pin 131 can be downwards inserted into the through hole 113 under the action of the elasticity of the elastic member 133, and the elastic member 133 can pre-tightly act on the locking pin 131 to prevent the locking pin 131 from easily separating from the through hole 113 on the first bending member 11. Further, the elastic member 133 is a spring sleeved outside the locking pin 131, and the locking pin 131 can limit the spring, so that the spring is prevented from bending deformation in the process of stretching.

In addition, a wrench 134 is disposed between the stopper 132 and the second bending member 12, the bottom of the wrench 134 abuts against the upper surface of the second bending member 12, the top of the wrench 134 abuts against the lower surface of the stopper 132, the wrench 134 is clamped between the stopper 132 and the second bending member 12 under the elastic force of the elastic member 133, a waist-shaped circular groove 1341 is formed in the end of the wrench 134, and the wrench 134 is sleeved outside the locking pin 131 through the waist-shaped circular groove 1341. When the worker needs to move the locking pin 131 upwards, the wrench 134 can be pressed downwards, after the wrench 134 is pressed, the portion of the wrench 134 sleeved on the locking pin 131 can be inclined, so that the plug 132 and the locking pin 131 are jacked up, the elastic piece 133 is compressed, and in the process, the wrench 134 moves in the horizontal direction relative to the second bending piece 12 due to the existence of the kidney slot 1341, so that the upward movement of the locking pin 131 is adapted. When the second bending member 12 rotates relative to the first bending member 11 until the perforation 113 is aligned with the through hole 122, the worker releases the wrench 134, and the locking pin 131 can automatically reset under the action of the elastic force of the elastic member 133, so that the lower end of the locking pin 131 is inserted into the perforation 113, and the locking relationship between the first bending member 11 and the second bending member 12 is realized again, so that the operation is simple and convenient.

In other embodiments, not shown, the locking structure 13 may also include only a fixing bolt, and at this time, the first bending member 11 and the second bending member 12 may be locked by the fixing bolt after being rotated in place and engaged with a fixing nut, specifically, the fixing bolt may pass through the first bending member 11 and the second bending member 12 in sequence and then be locked by the fixing nut.
