As shown in fig. 1-5, an improved glass sucker comprises a base 1, a sucker arranged at the bottom of the base 1, and a vacuum pump arranged at the top of the base 1 and matched with the sucker 1; the sucker comprises a baffle plate 2 connected to the bottom of the base 1 and a sealing strip 3 which is arranged around the baffle plate 2 and has deformation elasticity, and the sealing strip 3 is connected with the base 1; a first extension part 31 and a second extension part 32 which correspondingly extend towards two sides are arranged on two sides of the bottom of the sealing strip 3, specifically, an inverted V-shaped sealing groove 33 is formed between the first extension part 31 and the second extension part 32, and the sealing strip 3, the first extension part 31 and the second extension part 32 are integrally formed; the first extension 31 is located outside the second extension 32 and the bottom of the first extension 31 is lower than the bottom of the second extension 32. By the arrangement, the sealing performance and stability in operation can be improved by using the newly designed sealing strip 3.

Wherein, as shown in fig. 5, be provided with a slot 4 that corresponds the upper end of inserting sealing strip 3 in the bottom of base 1, the upper end detachably of sealing strip 3 installs in slot 4 to can conveniently dismouting sealing strip 3, the convenience is changed alone when sealing strip 3 damages, does not need whole sucking disc to change, thereby has reduced use cost.

As shown in fig. 5, two sides of the slot 4 are respectively provided with a clamping strip 6, and two sides of the upper end of the sealing strip 3 are respectively provided with a clamping groove 5 corresponding to the clamping strip 6; the card strip 6 is correspondingly clamped in the card slot 5. In this embodiment, the strip 6 extends along the periphery of the base 1, and the slot 5 extends along the periphery of the sealing strip 3. Can make things convenient for sealing strip 3 to connect on slot 4 through the block structure of above-mentioned card strip 6 and draw-in groove 5, of course, should know by technical personnel in the art, still can other structures to the dismantled connected mode of sealing strip 3 and slot 4, only need can fix a position card strip 6.

Preferably, as shown in fig. 5, the thickness of the first extension 31 is gradually reduced from top to bottom, and the thickness of the second extension 32 is also gradually reduced from top to bottom. More specifically, with respect to the shape setting of the first extension 31 and the second extension 32, when the glass is not sucked, that is, when the sealing tape 3 is in a natural state, the first extension 31 is in an arc shape protruding outward, and the second extension 32 is in an approximately vertically downward shape. By the arrangement, the first extension part 31 and the second extension part 32 can be more easily attached to the glass in a contact manner, and the stability and the sealing property of the two parts can be improved.

In the present embodiment, the weather strip 3 is made of rubber, so that it can be ensured that it has sufficient deformation elasticity, and the sealing property of the weather strip 3 in use can be ensured. Of course, the baffle plate 2 can also be made of rubber, so that the glass can be prevented from being scratched when the baffle plate is in contact with the glass.

As shown in fig. 1 and 3, the device further comprises a buffer mechanism 8 connected to the base 1; the buffer mechanism 8 comprises a positioning plate 81, a telescopic spring 82 and a guide rod 83; the lower end of the guide rod 83 is fixedly connected with the base 1, and the upper end of the guide rod can penetrate through the positioning plate 81 in a vertically movable manner; the extension spring 82 is sleeved on the guide rod 83, and two ends of the extension spring 82 respectively abut against the positioning plate 81 and the base 1. The buffering effect can be conveniently achieved by the above arrangement using the movable guide bar 83 and the spring 82 having the expansion and contraction force.

Specifically, as shown in fig. 1, in order to facilitate positioning of the guide rod 83, a first mounting through hole 84 is provided in the base 1, and a second mounting through hole 85 corresponding to the first mounting through hole 84 is provided in the positioning plate 81; the lower end of the guiding rod 83 penetrates into the first mounting through hole 84 and is fixed with the base 1, and specifically, the guiding rod 83 can be fixed in a threaded connection mode so as to be convenient to disassemble and assemble, and the upper end of the guiding rod 83 penetrates into the second mounting through hole 85 and is movably connected with the positioning plate 81. In order to prevent the guide rod 83 from being removed from the positioning plate 81, a nut 86 is provided at the top of the positioning plate 81 to be screwed to the top of the guide rod 83, so that the guide rod 83 can be pressed by the nut 86.

As shown in fig. 1, in the present embodiment, four guide rods 83 and four extension springs 82 are provided correspondingly for improving stability; the four guide rods 83 are symmetrically distributed on the base 1 and the positioning plate 81, and the four extension springs 82 are correspondingly sleeved on the four guide rods 83.
