Description

Sun umbrella opening and closing locking device and sun umbrella Technical Field The utility model relates to the technical field of sun umbrellas, in particular to a sun umbrella opening and closing locking device and a sun umbrella. Background In courtyard, balcony, swimming pool, outdoor area of dining room etc. often be equipped with outdoor sunshade, outdoor sunshade's overall dimension is great, and manual struts has certain operation degree of difficulty, in order to be convenient for open or close the operation to outdoor sunshade, outdoor sunshade is equipped with motor drive's operating structure generally, and the user can be conveniently through the corotation or the reversal of operation motor, and then control the opening or the closure of sunshade. In the prior art, in order to solve the accidents such as faults or power failure of a motor on the sunshade, the sunshade can still be manually operated, and a corresponding manual operation device is arranged on the outdoor sunshade. For example, a patent with the publication number CN221042542U is entitled "a longitudinal hand-operated dc motor for a sunshade of an automobile", which is provided with a self-locking planetary mechanism at an output shaft of the motor, the self-locking planetary mechanism comprises a fixed gear sleeve, a transmission gear sleeve and a planetary frame respectively arranged in the fixed gear sleeve, and the sun gear is driven to drive the output shaft of the dc motor to rotate by manually rotating a crank handle under the condition that the motor is damaged or has a power failure, so as to close the sunshade assembly. In the above-mentioned technique, through arranging self-locking planetary mechanism at the output shaft of motor, utilize the cooperation between self-locking planetary mechanism and the sun gear to realize the unidirectional rotation of hand crank, its internals is more, and the structure is comparatively complicated, and follow-up installation assembly and maintenance degree of difficulty are big, and the reliability reduces, and the fault rate is high. Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to provide the sunshade opening and closing locking device and the sunshade, which have simple structure and are convenient to adjust. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: In a first aspect, the present application provides an opening and closing locking device for a parasol, comprising: An operation hole is formed in one side of the shell; The large bevel gear is rotatably arranged in the inner cavity of the shell, a connecting hole which is convenient for the hand crank to be inserted and rotated is formed in the outer side end surface of the large bevel gear, and the connecting hole is communicated with the operating hole; The main bevel gear is rotatably arranged at the bottom of the inner cavity of the shell and meshed with the large bevel gear, and the main bevel gear and the bottom end of the shell form a transverse sliding connection which can be far away from or close to the large bevel gear; The motor is fixedly connected with the main bevel gear; The main bevel gear is fixedly arranged on the adjusting component, the adjusting component is arranged at the bottom end of the shell, and the adjusting component is used for driving the main bevel gear to transversely slide along the shell; The driven bevel gear is rotatably arranged at the upper part of the inner cavity of the shell, and is meshed with the large bevel gear. Further, the adjusting component comprises a sliding block and a pair of adjusting bolts, the sliding block is transversely and slidably arranged at the bottom end of the shell, the pair of adjusting bolts are respectively arranged at two opposite sides of the sliding block along the sliding direction parallel to the sliding block, a mounting hole is formed in the bottom end of the sliding block, the motor is fixedly arranged on the sliding block, an output shaft of the motor vertically penetrates through the mounting hole to be connected with the main bevel gear, and one end of each adjusting bolt penetrates through the shell to be in interference connection with the output shaft of the motor.
