Description

Hidden handle quick release structure

This creation is about a quick release structure, especially a quick release structure with a hidden handle.

According to the conventional quick-release structure for hiding the driving handle, please refer to the figures 9 to 12, which includes: a shaft 40 which is a hollow round rod body to form a rod through hole 41 therein, the rod A circular magnetic member 42 is fixed in the through hole 41. The outer end of the shaft 40 is provided with a threaded portion 43. The outer end of the shaft 40 is provided with an outer thread 44, and a round shaft head 50 is provided with an inner screw hole 51. The threaded portion 43 of the shaft 40 is screwed, and a slot 52 is formed at the front end to communicate with the inner screw hole 51. The slot 52 is cut through the two sides of the round shaft, and the slot 52 is two The side is respectively provided with a side hole 53 leading to the slot. The outer periphery of the rear end of the round shaft head 50 is provided with an outer concave ring groove 54. A stop ring 60 is provided with a through hole 61 at the center thereof. An inner ring flange 62 is disposed on the outer peripheral edge of the opening, and a ring tooth 63 is disposed on the inner end surface thereof. The inner ring flange 62 of the stop ring 60 is fitted into the outer ring groove 54 of the circular shaft head 50 to make the stop ring. 60 is rotatably engaged with the round shaft head 50, and the screw hole 51 of the round shaft head 50 is screwed with the threaded portion 43 of the shaft 40, so that the shaft 40 passes through the through hole 61 and the circular shaft Head 50 combined with one, one The movable handle 70 is a flat plate-shaped handle made of metal. The driving handle 70 has a handle 71 and a handle 72. The two sides of the drive handle 70 are respectively recessed along the longitudinal axis of the handle 72. a guide groove 73, the handle body 72 is inserted into the rod through hole 41 through the inner screw hole 51 through the slot 52 of the round shaft head 50, so that the handle 71 is immersed in the slot 52, and the handle body is The end of the 52 is attracted by the magnetic member 42. The two steel balls 80 are respectively assembled into the side hole 53 by a spring 81, and are fixed to the side hole 53 by a stopper 82 to be positioned. The steel ball member 80 is embedded in the guiding groove 73, so that the driving handle 70 can slide in the length of the front and rear ends of the guiding groove 73, and the rear end of the guiding groove 73 is restricted by the latching member 80. The driving handle 70 can not be disengaged, and the steel ball member 80 can be used as a rotating shaft, so that the driving handle 70 can be rotated along the slot in the slot 52, so that the driving handle 70 forms the circular shaft head 50 and the shaft. The force arm of 40 can be deflected by left and right to drive the external thread 44 of the shaft 40 to rotate. With the above configuration, the driving handle 70 can be pulled out from the rod through hole 41 of the shaft 40 when needed, and the driving handle 70 is biased to drive the shaft 40 to rotate and rotate without When in use, the driving handle 70 can be retracted into the rod through hole 41 of the driving handle 40, which has the function of hiding.

Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reasons are as follows: (1) The conventional structure is complicated, it does increase the structural manufacturing process and time, and the shaft 40 and the circular shaft The heads 60 are combined by a screw lock, and the configuration of the thread segments is not easy. The assembly area of the shaft 40 and the round shaft head 60 needs to be increased, which leads to an increase in the volume of the structure, resulting in an increase in structural cost and lack of economic benefits. By.

(2) The shaft 40 is provided with a threaded portion 43 at one end for the circular shaft head 50 to be fixedly fixed by the inner screw hole 51, and the driving handle 70 is pulled out to be limited to the round shaft head via the steel ball member 80. 50, when the driving handle 70 rotates, the rotating shaft is transmitted to the shaft 40 through the round shaft head 50, so as to achieve the rotation of the screw 40, so that the shaft 40 and the round shaft head 50 are also The combination of the screw locks causes the driver handle 70 to have the doubt that the round shaft head 50 is loosely separated from the shaft 40 during the force-applying process, and the accuracy of the screw-rotation linkage is lacking, and the rotation of the shaft 40 cannot be surely achieved. Actuator.

(3) The circular shaft head 50 is configured to combine the driving handle 70 by the cooperation of the two steel ball members 80 and the spring 81, and the driving handle 70 can be slidably displaced along the two steel ball members 80 by the guide groove 73, and more The end of the guide groove 73 is restricted by the two steel ball members 80 and cannot be detached. Therefore, the guide groove 73 and the two steel ball members 80 are easily worn under the long-term displacement friction, and the tolerance is increased, so that the steel ball member 80 has the doubt that it is separated from the side hole 53. Further, it is slid out from the guide groove 73, and the drive handle 70 is also released from the round shaft head 50 by the limitation of the steel ball member 80, which is inconvenient and missing in use of the structure, and lacks practicality.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.
