Detailed Description
The embodiment of the application provides a locking device of flexible stand for the locking structure who solves current flexible stand easily leads to extending the surface of post to take place to cave in because of locking screw locking force is too big, damages the quality of product, and the technical problem of installation and dismantlement are not convenient for to the position that needs manual fixed lock nut when installation and dismantlement.
In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the embodiments described below are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 to 4, an embodiment of the present application provides a locking device for a telescopic pillar, including: the device comprises a sleeve pipe 1, an extension column 2 and a locking component 3; the top of the sleeve pipe 1 is sleeved with a locking component 3, the extension column 2 is inserted into the sleeve pipe 1, the locking component 3 comprises a locking sleeve 31, a locking nut 32 and a knob 33, the locking sleeve 31 is internally provided with a locking wall 311 in a ring shape, the locking wall 311 is provided with two notches to form a pressing sheet 312 with elastic deformation, and the pressing sheet 312 is provided with a placing groove 313 for placing the locking nut 32; the sleeve pipe 1 is provided with a through hole 11, the knob 33 is provided with a locking screw 331, the locking screw 331 and the through hole 11 correspond to the position of the placing groove 313, and the knob 33 is rotated to drive the compression sheet 312 to abut against the extension column 2.
The sleeve pipe 1 is a fixed part of a telescopic upright post, the extensible length of the telescopic upright post is determined by an extension post 2 inserted on the sleeve pipe 1, the telescopic upright post is locked by a locking component 3, a locking wall 311 is annularly arranged in the locking sleeve 31, the inner diameter of the locking wall 311 is larger than the outer diameter of the extension post 2, the extension post 2 is inserted in the locking wall 311, the height can be easily adjusted, a knob 33 is arranged outside the locking sleeve 31 through the matching of a locking screw 331 and a locking nut 32, when the knob 33 is rotated, the locking screw 331 is screwed into the sleeve pipe 1, a compression sheet 312 is subjected to locking force exerted by the locking screw 331 and then elastically deforms, so that the gap between the extension post 2 and the locking wall 311 is reduced until interference fit is achieved, and the position of the extension post 2 is locked and fixed; when the height of the telescopic upright column needs to be adjusted again, the knob 33 is rotated outwards, the locking force borne by the pressing sheet 312 is cancelled, the gap between the extension column 2 and the locking wall 311 is continuously enlarged, so that the state that the height can be adjusted freely is restored, the force borne by the extension column 2 has the buffering effect of the pressing sheet 312, deformation is not prone to occurring, the placing groove 313 formed in the pressing sheet 312 is used for placing the locking nut 32, the locking nut can move along with the locking sleeve 31 during installation and disassembly, the nut does not need to be manually held to match with a screw, the installation steps are simplified, the placing position is stable, and the locking nut does not easily fall off.
Specifically, be equipped with installation department 332 on the inside of knob 33, set screw 331 is fixed in installation department 332, the high lateral wall height that is greater than knob 33 of installation department 332, knob 33 rotates the certain limit toward the inside of quill tube 1, installation department 332 can butt the outer wall of quill tube 1, thereby stall, avoid exceeding the limit because of the too big elastic deformation who leads to compressing tightly piece 312 of locking force that set screw 331 applyed, the fracture takes place, and then the outer wall that extends post 2 also receives wearing and tearing, lead to locking device to lose efficacy and damage product quality simultaneously. The outer surface of the knob 33 is provided with anti-slip lines, which is convenient for operation when the knob 33 is rotated.
More specifically, be equipped with a plurality of strengthening rib 333 on the locking wall 311, the lock sleeve 31 is installed behind sleeve pipe 1, strengthening rib 333 with there is the clearance between the inner wall of sleeve pipe 1, the back of locking wall 311 is located to strengthening rib 333, and compresses tightly piece 312 and place groove 313 and all be equipped with strengthening rib 333, has increased structural strength, locks better and extends post 2, when lock sleeve 31 installs at sleeve pipe 1, the clearance that exists between strengthening rib 333 and the inner wall of sleeve pipe 1 is favorable to the operation of installation, and the strengthening rib 333 has the space that moves back when extending post 2 and receiving the power of compressing tightly piece 312 and moving back, avoids extrudeing sleeve pipe 1 because of locking force is great.
In this embodiment, rotate knob 33, drive locking screw 331 toward the inside screw in of sleeve pipe 1, drive compression piece 312 and extension post 2 butt, the height of flexible stand is adjusted to the height that the locking extended column 2, lock nut 32 has place groove 313, follow lock sleeve 31 and remove with dismantling in the installation, do not need manual fixed position or drop inside because of breaking away from the screw, be difficult to take out, utilize lock wall 311 and compressing tightly piece 312 to lock extension post 2, the locking force has been cushioned, it is not fragile to extend post 2 surface, the locking structure of having solved current flexible stand easily leads to extending post 2's surface emergence because of locking screw 331 locking force is too big sunken, damage the quality of product, the position that needs manual fixed lock nut 32 during installation and dismantlement, be not convenient for the technical problem of installation and dismantlement.
Variations and modifications to the above-described embodiments may occur to those skilled in the art, which fall within the scope and spirit of the above description. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and variations of the present invention should fall within the scope of the claims of the present invention.
