INO
00 0 5 Detailed Description of Specific Embodiments I Referring to Figs. 1, 2, 5 and 6, a fixing device 100 comprises a housing 1, a Ssuction cup 2, a mini-sized vacuum pump 9 contained in the housing 1, wherein the pump 9 is connected to an air outlet 22 on the top 220 of the suction cup 2 via a pipe 82. On the housing 1, a power switch 3 is provided, which could be turned on to connect a battery pack 7 to a circuit, the vacuum pump 9 is powered on thereby and starts to operate, the air under the suction cup 2 is thus exhausted out through the pipe 82 from the air outlet 22. The mini-sized vacuum pump 9 is well known in the art and is commercially available, so it will not be described any more herein.
Referring to Fig. 2, the suction cup 2 includes a flexible skirt 24 made of elastic material such as rubber, and whose peripheral edge 240 is smooth and lies in a plane. Consequently, to place the fixing device 100 on a smooth surface such as a wall surface, and switch on the power switch 3, the vacuum pump 9 will then continually evacuate the air in the space 210 defined between the skirt 24 and the surface, such that the air pressure of the space 210 is greatly reduced and even drops to vacuum, and the fixing device 100 is firmly secured on the surface therefore.
Referring to Figs. 3 and 4, the fixing device 100 further includes a fixing pad which can be taken out of a locking frame 55 of the housing 1. The fixing pad includes a pair of protrusions 53 at one side and an elongated recess 54 at the opposite side. The fixing pad 5 further includes a first support surface 51 and a second support surface 52 with different shapes, it is preferred that the first support surface 51 is spherical and the second support surface 52 is flat.
Moreover, a magnet 56 is embedded in the fixing pad 5. As can be seen from -7- Figs. 3 and 5, the locking frame 55 comprises a pair of abutments 57 for Csupporting the protrusions 53 thereon, and a latch 61 connected with a pusher 6.
The latch 61 can be caught into the recess 54 of the fixing pad 5 and thereby to lock the fixing pad 5 in the locking frame 55. The pusher 6 is used to pull back the latch 61 and thereby to release the fixing pad 00 Various articles with attaching surface of different shapes can be attached to the _fixing device 100 because of the applying of the above-mentioned fixing pad 5. As Ishown in Fig. 9, a laser level 110 is attached on the fixing device 100 of the present invention. The laser level 110 comprises a concave spherical bottom surface, which can engage with and be attracted to the convex spherical top surface 51 of the fixing pad 5, such that the laser level 110 can be turned in the direction of arrow 111 and is inclinable in the direction as shown by arrow 112, thereby the laser line L1 can be adjusted in all directions. Persons skilled in the art are directed to the laser level 110 disclosed in CN Patent No. ZL 200420028106.4, which is wholly incorporated by reference herein, as well as to its equivalents.
It is shown in Fig. 10 that another laser level 120 with a flat bottom surface is attached on the second support surface 52 of the fixing pad 5, such that the laser level 120 can be turned in the direction as shown by arrow 121 with the laser line L2 being turnable together therewith.
In addition to being used to attach a laser level 110 or 120 on a wall, the fixing device 100 is also used for supporting other articles. For example, as shown in Fig. 11, a laser target 130 can be supported to a wall surface. Moreover, the fixing device 100 can be equipped with a hook, a latch dog and the like for carrying articles of other shapes.
As shown in Figs. 6 and 7, in order to quickly take down the fixing device 100 from the surface on which it has been attached, the top 220 of the suction cup 2 comprises an air inlet 21 connected with one end of an air intake pipe 81, the other end of which is connected with a valve 400. Thus, when the valve 400 is opened, the space 210 is communicated to the atmosphere via pipe 81 and air -8goes into the space 210 via the air inlet 21 so that the vacuum in the space 210 is broken. At this time, a user can easily take down the fixing device 100 from the surface.
Referring now to Fig. 7, the valve 400 will be described in great detail hereinafter.
I 5 The valve 400 includes a valve body 42, which is closely fitted within the pipe 81 00 and has a stepped internal chamber comprising a first chamber 421, a second _chamber 422, wherein the inner diameter of the first chamber 421 being smaller Ithan that of the second one 422. Furthermore, a screw 45 is fixed on the distal end of the second chamber 422 of the valve body 42; an axial slot 46 is provided on the wall of the valve body 42 for communication between the pipe 81 and the second chamber 422, and a spring is compressed in the second chamber 422 with one end biasing on a valve plug, which is preferably a steel ball 43. The steel ball 43 blocks upon the valve port 423 between the first chamber 421 and second chamber 422 under the biasing force of the spring 44, so that the air communication between the second chamber 422 and the first chamber 421, and consequently the atmosphere, is blocked. Therefore, the second chamber 422, pipe 81 and space 210 in the suction cup 2 form a serial sealed space. Further referring to Fig. 7, a valve bar 41 is loosely inserted in the first chamber 421 of the valve body 42 with its free end being contactable to the ball 43. A button 4 is provided on the other end of the bar 41 for user's operation. When the button 4 is pressed, the ball 43 is pushed away from the valve port 423 by the bar portion 41.
Thus, the air pours into the space 210 in the suction cup 2 through the second chamber 422, slot 46 and pipe 81. As a result, the vacuum is broken.
As shown in Figs. 2 and 8, there are provided control means which include a protrusion 23 extending downward from the top 220 of the suction cup 2, and a control rod 230 disposed in the housing 1 with one end being supported on the top of the protrusion 23 and the other end goes through a spring 231 and being in contact to a trigger 232. When the fixing device 100 is attached on a smooth surface such as glass, glazed tile, and the like, the contact between the suction cup 2 and the surface will be very compact. When the vacuum pump 9 draws air out, the air pressure in the space 210 is decreased rapidly, and the distance between the top 220 of the suction cup 2 and the surface is reduced gradually.
When the distance is reduced to a certain value, the downward protrusion 23 begins to be pressed upward so as to push up the control rod 230 and further to activate the trigger 232, which will then shut down a power switch (not shown) and thus the vacuum pump 9 stopped working. Due to the close contact between the suction cup 2 and the surface, the vacuum in the space 210 is not easy to be Nbroken even if the vacuum pump 9 does not operate. However, air will slightly flow 00 into the space 210 more or less, and the space 210 will expand little by little, and _the protrusion will free from being pressed by the attached surface, such that the Ncontrol rod 230 will disengage from the trigger 232, and the vacuum pump 9 is restarted to operate. With such a configuration, energy-saving can be effectively achieved.
The fixing device 100 can also be integrated in a single unit with some objects usually used on a wall surface.
While the invention has been described and illustrated in the preferred embodiment, the description and illustration is exemplary and explanatory but not indented to limit the invention to the extent disclosed herein. It is obvious that those who are skilful in this field can make many changes and modifications without departing from the spirit and scope of the invention. Therefore, all changes and modifications based on the innovation of the invention are fall in the invention's scope claimed in the appended claims.
