Background

The leak detector is an instrument for industrial leak detection, and can perform leak detection of a sealing member. The leak detector generally includes a vacuum gauge and a valve seat, and the vacuum gauge and the valve seat are required to be fixed as a whole when the leak detector performs leak detection operation.

In the prior art, a vacuum gauge and a valve seat are generally fixed through a pressure foot, and the pressure foot is used for tightly pressing a flange of the vacuum gauge on the valve seat so as to connect the vacuum gauge with an inner cavity of the valve seat. The four common instrument press feet are independent from each other, but the vacuum gauge is often in a transverse state for the reasonable distribution of space and the requirement of functions, and when the vacuum gauge in the transverse state is fixed on a valve seat, the independent press feet are inconvenient to adopt. Because the presser foot is in a drooping state when the screw is not fastened, one hand is needed to hold the vacuum gauge, the other hand is needed to rotate the presser foot to the correct direction, and the screw of the presser foot needs to be fastened, so that the operation is difficult to be performed oppositely; meanwhile, because the inner space of the instrument is limited, the vacuum gauge after being installed is extremely inconvenient to detach from the valve seat, which brings great difficulty to the operation and may damage the instrument.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, fig. 2 and fig. 3, the utility model provides a leak detector vacuum gauge mounting structure, including the presser foot, the presser foot is fixed on disk seat 4, the presser foot includes a set of last presser foot 1 and the lower presser foot 3 that sets up about being, go up presser foot 1 and lower presser foot 3 all include the top be equipped with draw-in groove 9 the base 7 and with set up the clamp plate 8 in draw-in groove 9, all be provided with through-hole 10 on base 7 and the clamp plate 8, clamp plate 8 and base 10 are fixed from top to bottom through mounting 6, the clamp plate passes through mounting 6's regulation along keeping away from or being close to draw-in groove 9 direction motion, connect through elastic component 2 between two upper and lower bases.

Based on above-mentioned technical scheme, because go up presser foot 1 and the connection of presser foot spare elastic component down, can not lead to under the state of not fastening the condition that upper presser foot 1 and lower presser foot drooped, when avoiding independent presser foot to fix the vacuum gauge one by one, need manually break suitable position with drooped presser foot off with the fingers and thumb, convenient operation is fixed through elastic component 2 between the two simultaneously, only needs the deformation through elastic component 2 just can realize the conversion of presser foot angle. It should be noted that the elastic member may be an elastic object capable of achieving this function in the prior art, and the elastic member used herein is a spring. The presser foot adopts a combined form of the base 7 and the pressing plate 8, because the base 7 and the pressing plate 8 are detachably fixed, the fixing of the vacuum gauges 5 with different heights can be realized by adjusting the pressing plate 8 up and down, one side of the pressing plate 8 is arranged in the clamping groove 9 during the fixing, and the pressing plate 8 is not easy to incline, move and the like under the fixing of the groove plate; when the vacuum gauge 5 is detached from the valve seat 4, the vacuum gauge 5 can be detached only by loosening the contact part of the fixing piece and the pressing plate 8 and moving the pressing plate 8 out of the clamping groove 9. Because the pressing plate 8 separated from the clamping groove 9 naturally sags under the action of gravity and cannot shield the vacuum gauge 5, the trouble that the vacuum gauge can be disassembled only by detaching the upper presser foot 1 and the lower presser foot 3 from the valve seat 4 when the vacuum gauge 5 is disassembled is avoided.

As shown in fig. 5, the clamping groove 9 comprises a top notch 91 and a side notch 92 located on one side of the top notch 91, the side notch 92 is opposite to the bottom of the vacuum gauge 5, one side of the pressing plate 8 is arranged in the clamping groove 9, the other side of the pressing plate 8 extends out of the side notch 92 and is located above the vacuum gauge 5, and the height of the clamping groove 9 is adapted to the height of the pressing plate 8. When clamp plate 8 was arranged in draw-in groove 9, clamp plate 8 was kept away from draw-in groove end pressure and is fixed the department in 5 bottoms of vacuum gauge, adopts draw-in groove 9 to fix the clamp plate for it is fixed more firm, avoids in the use, and clamp plate 8 takes place the rotation and leads to vacuum gauge 5 to drop from disk seat 4.

As shown in fig. 3, the fixing member 6 includes a bolt 61 passing through a through hole 10 of the base 7 and the pressure plate 8 and having a bottom disposed on the lower surface of the valve seat 4, a spacer 62 located above the pressure plate 8, and a nut 63 fixed above the spacer 62, wherein the diameter of the through hole 10 of the base 7 and the pressure plate 8 is larger than that of the bolt 61, and the distance from the top of the bolt 61 to the surface of the pressure plate 8 is larger than the thickness of the pressure plate 8. When the presser foot is fixed, the bolt 61 penetrates through the surface of the valve seat 4 to be transversely arranged, the base 7 connected through the elastic piece 2 is sleeved on the bolt 61, the pressing plate 8 is arranged in the clamping groove 9 on the base 7, the bottom fixing position of the vacuum gauge is arranged below the pressing plate 8, and the pressing plate 8 is fixed through the nut 63. The fixing position is firstly determined through the base 7, and then the vacuum gauge is firmly fixed by the vertical plate. The distance between the top of the bolt and the surface of the pressing plate 8 is larger than the thickness of the pressing plate 8, so that the bolt cannot fall off when the pressing plate 8 is removed from the clamping groove.

As shown in fig. 1 and 5, fixing holes 11 are formed in the side faces of the bases 7, the fixing holes 11 of the upper and lower bases are symmetrically arranged, two ends of the elastic member 2 are respectively fixed in the fixing holes 11 of the upper and lower bases, and the length of the elastic member 2 in a natural state is adapted to the distance between the upper and lower fixing holes 11. The elastic part 2 ensures that the base 7 is fixed in position and does not droop, so that the mounting difficulty is reduced; on the other hand accessible deformation changes the angle of fixing base to drive clamp plate 8 and find suitable fixed position, make the fixed more firm of vacuum gauge 5, avoid droing in the use.

As shown in fig. 1, the two sets of the presser feet are arranged symmetrically, the vacuum gauge 5 is primarily fixed by one set of the presser feet, then the other side of the vacuum gauge 5 is fixed by the other set of the presser feet, and finally the two sets of the vacuum gauges are fastened. Two sets of presser feet cooperate and use, when guaranteeing fixed fastness, simplified fixed process, avoid unnecessary operation flow, reduce the manpower.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
