DETAILED DESCRIPTION

[0022] The utility model discloses a further detailed description of the specific implementation of the utility model below combining with the drawings and examples. The following examples are used to explain the utility model, but not to limit the scope of the utility model.

[0023] Reference Figures 1 to 7 As Figures 1 to 7 The utility model discloses a kind of stand bases, including fixed seat 10, the fixed seat 10 is equipped with sucking disc subassembly 20, the fixed seat 10 is equipped with installation site 11;The sucking disc subassembly 20 includes shell 21, the shell 21 back is equipped with sucking disc 22, the shell 21 is also equipped with the control piece 23 for controlling the negative pressure generated by sucking disc 22 suction, the shell 21 is loaded into installation site 11 from back to front and is locked and fixed by locking piece 24 from front to back;The back of sucking disc 22 is equipped with mucilage layer 221.

[0024] In the above structure, since sucking disc 22 with mucilage layer 221 cannot be directly removed in the state of relieving negative pressure after being fixed, the sucking disc 22 subassembly 20 and the fixed seat 10 are detachable, the sucking disc 22 subassembly 20 is used as replacement part, when the stand needs to be transferred together with the fixed seat 10, the locking piece 24 is loosened to separate the fixed seat 10 and the shell 21 of the sucking disc 22 subassembly 20, and then the new sucking disc 22 subassembly 20 is loaded to realize ectopic installation.

[0025] In the embodiment, the installation site 11 is hole-shaped, one side of the installation site 11 towards the rear end of the fixed seat 10 is equipped with ladder groove 111, the inner wall of the ladder groove 111 is equipped with positioning key 112;The outer side wall of the shell 21 is equipped with baffle 211 that is adapted to abut with the ladder groove 111, the baffle 211 is equipped with positioning groove 212 that is adapted to form circumferential positioning with the positioning key 112;The shell 21 of one side of the baffle 211 towards the front of the shell 21 is equipped with first screw thread 213;The first screw thread 213 is screwed with the locking piece 24 after passing through the installation site 11.

[0026] In the above structure, the control member 23 is preferably a rotating disc, and the positioning key 112 and the positioning groove 212 are adapted to avoid the shell 21 from rotating with the control member 23 or the locking member 24 when the rotating locking is performed.

[0027] In the embodiment, the first thread 213 is an external thread, and the locking member 24 is annular and abuts against the end face of the installation site 11 while being screwed with the first thread 213.

[0028] In the above structure, the locking member 24 is a locking ring, and the shell 21 is fixed with the fixing base 10 by screwing with the first thread 213.

[0029] In the embodiment, the shell 21 is provided with a cam disc 25 on the front face and fixed with the control member 23, the cam disc 25 is provided with a guide slope 251 on the back face away from the suction disc 22, the suction disc 22 is provided with a pull rod 222 penetrating through the shell 21 and the cam disc 25, and the pull rod 222 is provided with a guide pin 223 adapted with the guide slope 251 on the extended end. When the control member 23 drives the cam disc 25 to rotate, the guide pin 223 is pushed by the guide slope 251 to pull the pull rod 222 to make the suction disc 22 perform the suction action.

[0030] In the above structure, when the cam disc 25 rotates, the pull rod 222 gradually moves forward of the fixing base 10 by the adaptation of the guide pin 223 and the guide slope 251 to establish the negative pressure for the suction disc 22.

[0031] In the embodiment, the cam disc 25 is provided with an inner buckle groove 252 in the circumferential direction, the control member 23 is provided with a buckle hook 231, the hook tip of the buckle hook 231 faces outward and buckles with the inner buckle groove 252, the side wall of the control member 23 is provided with an unlocking hole 232 corresponding to the buckle hook 231, and the buckle hook 231 is pushed out of the inner buckle groove 252 by the rod-shaped object inserted into the unlocking hole 232 to realize the separation of the control member 23 and the cam disc 25 (for reference Figure 5 ).

[0032] In the above structure, since the cost of replacing the entire suction disc 22 assembly 20 is high (the suction disc is blocked by the shell 21 and cannot be lifted up and torn off from the edge), the suction disc 22 can be replaced alone according to the needs (manual ability) of the user. Specifically, the control member 23 and the cam disc 25 are separated by pushing the buckle hook 231 out of the inner buckle groove 252 by the rod-shaped object, and then the cam disc 25 and the shell 21 are separated from the suction disc 22 by taking out the guide pin 223. At this time, only the suction disc 22 is adhered to the fixed surface, and the suction disc 22 can be removed by lifting up the edge and pulling down the adhesive layer 221 from the fixed surface, and then a new suction disc 22 can be reassembled.

[0033] In the embodiment, the guide bevels 251 are two and are arranged along the circumferential direction of the cam disc 25, the guide pin 223 penetrates the pull rod 222 and the two ends of the guide pin 223 are respectively matched with the guide bevels 251, the high end of the guide bevel 251 is provided with a locking groove 253, and when the guide bevel 251 guides the guide pin 223 to pull the pull rod 222 to make the suction disc 22 perform the suction action, the guide pin 223 passes the high end of the guide bevel 251 and enters the locking groove 253 to be locked.

[0034] In the above structure, the guide bevels 251 are two and can improve the stability of the pull rod 222, and the guide pin 223 passing the high end of the guide bevel 251 and entering the locking groove 253 to be locked can avoid the reverse rotation of the cam disc 25.

[0035] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and the above assumptions of these improvements and modifications should be considered as the protection scope of the present application.
