The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1-12.
A steerable handle based on a wedge-shaped positioning pin structure for a medical vehicle comprises a handle body 1, a handle seat 2 connected with a vehicle body and a handle embedded shaft 3, wherein a handle seat cushion 13 (shown in figures 5 and 9) is sleeved at one end, connected with the vehicle body, of the handle seat 2, as shown in figures 1 and 6. One end of the handle embedded shaft 3 is fixedly arranged in the handle seat 2, and the other end thereof is rotatably positioned in the handle body 1 so as to ensure that the handle body 1 and the handle seat 2 can rotate mutually but cannot be axially separated. As shown in fig. 1, 5, 6, 9; the equal cloth has 8 handle seat constant head tank 5 (as shown in fig. 4, 8) on the relative terminal surface of handle seat 2 and handle body 1, in order to guarantee the intensity of handle seat constant head tank 5, can inlay on the relative terminal surface of handle seat 2 and handle body 1 during specific implementation has handle seat steel pad 4 (as shown in fig. 5), offer the jack that equals with handle seat constant head tank 5 quantity, diameter match on the handle seat steel pad 4, locating pin 6 passes this jack before insert in handle seat constant head tank 5 in order to increase the stability of locating pin 6. Two wedge-shaped positioning pins 6 (as shown in fig. 10) are installed in one end of the handle body 1 opposite to the handle seat 2, the main body shape of the positioning pins 6 can be cylindrical or polyhedral and is not easy to rotate, one end of each positioning pin 6 can be simultaneously inserted into or moved out of two adjacent handle seat positioning grooves 5 on the handle seat 2, the other end of each positioning pin 6 is respectively abutted against a corresponding reset spring 12, a slot 7 for inserting the lower end of an unlocking connecting rod is respectively arranged on the opposite surface of the end, one end of each slot 7 is of an inclined surface structure 8, and the inclined surface structure is matched with an inclined surface cut 10 corresponding to the lower part of the unlocking connecting rod 9 installed in the handle body 1 to realize the axial movement of the positioning pins; two inclined plane notches 10 (as shown in fig. 11) are symmetrically arranged at the lower part of the unlocking connecting rod 9, opposite planes of the third side are abutted against the bottom surfaces of the grooves 7 of the positioning pins 6 so as to prevent the positioning pins 6 from rotating in the movement process and only moving along the axial direction, and the two inclined plane notches are respectively matched with the corresponding inclined plane structures 8 on the two positioning pins 6, as shown in fig. 12. Install unlock button 11 (as shown in fig. 5, 9, this unlock button is conventional structure, have a great button suit can on the unlock connecting rod) in the upper end of unlock connecting rod, unlock connecting rod 9's lower extreme install stop nut 14, as shown in fig. 1, 6 to prevent to go up the bullet offside of unlock connecting rod 9, for simple to operate, offer the mounting hole that is used for mounting nut in handle body lower part, install connecting rod end cap 15 additional on the mounting hole. The lower end of the unlocking connecting rod 9 moves downwards when the unlocking button 11 is pressed, the two inclined plane notches 10 at the lower end of the unlocking connecting rod press the inclined plane structures 8 on the two positioning pins 6 to drive the positioning pins to move axially in the positioning pin holes (the state that the unlocking connecting rod is inserted in place is shown in figure 3, and the state that the unlocking connecting rod is separated from the inclined plane structures (wedges) 8 is shown in figure 7), thereby forcing one end of the positioning pin inserted into the positioning slot 5 of the handle seat to leave the positioning slot 5 of the handle seat, enabling the handle body and the handle seat to rotate relatively, after rotating to the position, when the unlocking button is released, the positioning pin 6 is popped up under the action of the reset spring 12 arranged at the other end of the positioning pin and is inserted into the handle seat positioning groove 5 on the handle seat again to realize the positioning of the handle body 1, meanwhile, the inclined notch 10 at the lower part of the unlocking connecting rod 9 is forced to move upwards to reset by the reaction force of the inclined structure 8 on the positioning pin 6.
In specific implementation, the double positioning pins 6 can be replaced by single positioning pins, the lower part of the corresponding pin release connecting rod 9 is only provided with one inclined plane notch 10, at the moment, the number of the handle seat positioning grooves 5 can be set at will, but the double positioning pins of the embodiment are still better in terms of working stability and reliability.
The utility model discloses a theory of operation is:
under the normal state, the side cut inclined plane 11 of the lower end of the unlocking connecting rod 9 is not contacted with the inclined plane structure (wedge) 8 of the wedge-shaped positioning pin 6, the positioning pin 6 penetrates through the handle seat steel pad 4 and extends into the handle seat positioning groove 5 on the handle 2, the handle body 1 and the handle seat 2 cannot realize relative rotation under the action of the positioning pin, and the state is shown in the figure 1. When the handle body 1 needs to be rotated to change the direction or position of the handle, the unlocking button 11 at the top of the handle body 1 can be pressed, the unlocking button 11 is pressed downwards, the cut product inclined plane 10 at the lower part of the unlocking connecting rod 9 extrudes the inclined plane structure (wedge) 8 (as shown in figure 12) on the wedge-shaped positioning pin 6, the inclined plane structure 8 overcomes the resistance of the return spring 12 after being pressed to drive the insertion end of the positioning pin 6 to leave the handle seat positioning groove 5, as shown in figure 6, the handle body 1 and the handle seat 2 can rotate relatively, when the handle body 1 is rotated to a required position, the unlocking button 11 can be released, the return spring pushes the insertion end of the positioning pin 6 to be inserted into the handle seat positioning groove 5, and meanwhile, the unlocking connecting rod is pushed upwards to the original position by the counter-acting force of the inclined plane structure (wedge) 8 on the. At this time, if the positioning pin is not completely inserted in place, the handle body 1 can be rotated back and forth by a small amplitude to ensure that the insertion end of the positioning pin is safely inserted into the handle seat positioning groove 5, and then the adjustment of the handle position is completed. Returning to the state shown in figure 1.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
