[0002] Hinged lever lock Figure 1 As shown in the figure, it is simple and reliable, and is one of the door lock types often used for shelter doors. Before installing the door lock, the lock shaft hole and the threaded installation hole must be punched on the door body. The installation hole needs to be based on the lock shaft hole. However, due to the large size of the shelter door body, the upper and lower adjustment gaskets of the hinge lever lock are far away from the lock shaft, making it difficult to determine the position, so the workshop made a self-made positioning tool.

[0003] The structure of the positioning tooling is as follows Figure 2 As shown, the middle part is used to position the door lock body, and sliders are provided on both sides that can slide on the aluminum bar to change the position. The sliders are used to position the upper and lower adjustment gaskets of the door lock. When installing the door lock on the cabin door body, it is usually placed flat on the workbench, the tooling is placed on the surface of the door body, and the tooling is manually pressed to drill holes.

[0004] The existing positioning tooling has the following disadvantages: the hole position in the middle part of the tooling is not adjustable, the main parts of different lock bodies are different, and the distances from the lock shaft to the surrounding mounting screws are different, so the existing tooling is not universal and is only suitable for one type of door lock; the existing tooling does not have a fixing function and relies entirely on manual pressing, which is prone to deviations during the drilling process; the door body is large in size and the aluminum bar is too long, the entire tooling takes up a lot of space, and the aluminum bar will deform and bend over time and cannot be used anymore.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] like Figures 3 to 5 As shown, this embodiment provides a cabin door lock installation and positioning tool, including a first plate 1 and two second plates 2, the two second plates 2 are symmetrically arranged on the left and right sides of the first plate 1, and are connected to the first plate 1 through a telescopic mechanism.

[0037] A cavity 11 is provided in the middle of the first plate 1, and three support bars 12 are provided in the cavity, which are used to support the orifice plate and avoid the first positioning hole on the orifice plate. A positioning shaft 13 is fixedly provided through the middle support bar, and the left and right support bars are located at the left and right ends of the cavity. The width of the left and right support bars is preferably 0.5-1 cm. As a support member, it should not interfere with the drilling process, so most of the area in the cavity should be left for drilling.

[0038] The orifice plate 3 is placed in the cavity 11. The orifice plate 3 is provided with an axial hole 30 and a first positioning hole 31. The axial hole 30 matches the positioning shaft 13. The first positioning hole 31 is used to position the mounting screw of the lock. The positioning shaft 13 is consistent with the lock shaft size of the lock body. One end of the positioning shaft matches the axial hole 30, and the other end is used to position the lock shaft hole on the door body. The orifice plate is replaceable. Different orifice plates 3 are replaced for different lock bodies, but they are all based on the positioning shaft 13, making the cavity universal.

[0039] In order to facilitate the locking and taking and placing of the orifice plate 3 , an unlockable locking mechanism for the orifice plate is also provided on the first plate 1 .

[0040] In this embodiment, the unlockable locking mechanism includes a clamping jaw 4 arranged on the first plate 1, and there are four clamping jaws 4 arranged around the cavity. The clamping jaw 4 is rotatably connected to the first plate; rotating the clamping jaw 4 can press one end of the clamping jaw 4 onto the orifice plate.

[0041] The clamping jaw 4 is preferably an arc-shaped or V-shaped spring sheet, one end of which is rotatably connected to the first plate 1 and the other end is in an open state. When the spring sheet is rotated, the end in the open state can fall on the orifice plate 3, and the orifice plate 3 is fixed in the cavity under the pressure of the spring sheet.

[0042] At the same time, after the orifice plate 3 is placed in the cavity 11, the upper surface of the orifice plate 3 is equal to the upper surface of the first plate 1, or is 0-2mm higher than the upper surface of the first plate 1; if the orifice plate is placed lower than the upper surface of the first plate, the clamp cannot contact the orifice plate well and cannot play a pressing role.

[0043] In this embodiment, the telescopic mechanism is a rolled spring steel ruler 4. Two spring steel rulers 4 are respectively located on both sides of the cavity, the base of the spring steel ruler 4 is fixed on the first plate 1, and the ends of the spring steel ruler 4 extend out and are fixedly connected to the corresponding second plate 2. The spring steel ruler 4 and the second plate 2 are symmetrically arranged on both sides of the first plate 1. The spring steel ruler 4 has a certain hardness, and will be significantly deformed when tilted during the elongation process, so as to ensure that the second plate will not be skewed on the horizontal plane. Preferably, the thickness of the first plate 1 and the second plate 2 is the same, so that when the second plate is pulled horizontally, the spring steel ruler will not bend up and down to avoid inaccurate readings.

[0044] Four second positioning holes 21 are also provided on the second plate 2, symmetrically in pairs, and the second positioning holes 21 are used to position the mounting screws of the adjustment gasket. The spring steel ruler 4 is marked with scales, and the initial scale line is collinear with the center of a certain positioning hole of the second plate 2; since the function of the spring steel ruler 4 is to determine the position of the adjustment gasket of the hinge lever lock, its indication should show the horizontal distance from the positioning hole of the adjustment gasket to the lock shaft, so the initial scale line should be aligned with a second positioning hole on the second plate, that is, the end of the spring steel ruler 4 is collinear with the axis of the two second positioning holes that are symmetrical up and down.

[0045] The reading position of the spring steel ruler 4 is the straight line where the edge line of the first plate 1 is located, which is expressed as the distance from the initial scale line to the axis of the positioning shaft 13. When the second plate 2 is pulled, the spring steel ruler is pulled out together with the second plate, and the scale displayed on it is L, that is, the horizontal distance L from the positioning shaft to the second positioning hole on the second plate. If the distance between the two second positioning holes in the horizontal direction of the second plate is L', then the distance from the positioning shaft to the other hole is L+L'.

[0046] The first plate 1 and the second plate 2 are also provided with a connecting mechanism, which is used to connect with the square door body.

[0047] In this embodiment, the connecting mechanism is a negative pressure adsorption connecting mechanism, and the first plate 1 and the second plate 2 are respectively provided with a first air pipe hole 61 and a second air pipe hole 62, the air pipe holes are connected to a vacuum pump, and the backs of the first plate 1 and the second plate 2 are embedded with sealing rings surrounding the air pipe holes.

[0048] Specifically, two sealing grooves 60 are provided on the back of the first plate 1, one of which surrounds the cavity 11 and the other is provided along the edge of the first plate 1. Sealing rings are embedded in the sealing grooves, and the first air pipe hole 61 on the first plate 1 is provided between the two sealing grooves. The second air pipe hole 71 of the second plate 2 is located in the center of the four second positioning holes, and a sealing groove 70 surrounding the second air pipe hole 71 is provided on the back of the second plate 2.

[0049] It is preferred to open an air chamber on the back side of the first plate 1 and the second plate 2, and the first air pipe hole 61 and the second air pipe hole 62 are opened in the air chamber, that is, a sink groove is opened between the two sealing grooves on the back side of the first plate 1, and a sink groove is opened in the area surrounded by the sealing groove on the second plate 2. The sink groove is used as an air chamber when the vacuum pump sucks air. Compared with the structure without an air chamber, it is easier to install the air pipe joint. The first plate 1 and the second plate 2 can be connected to the same vacuum pump or different vacuum pumps.

[0050] The vacuum pump uses a miniature vacuum pump, which is small in size and can be carried around. The first plate and the second plate are not subjected to strong external force when they are installed during operation, so the suction force of the miniature vacuum pump is sufficient to fix them. The miniature vacuum pump is preferably a gas sampling pump that can run dry. The vacuum pump draws air to form a vacuum state in the sealing ring, and the first plate and the second plate are adsorbed on the cabin door body by negative pressure. At this time, the backs of the first plate and the second plate fit the cabin door body to ensure stability without shaking during the drilling process.

[0051] The first plate 1 is provided with first hand positions 10 located on both sides of the cavity, and the first hand positions 10 are connected to the cavity. The edge of the second plate 2 is provided with an open second hand position 20. The first hand position is used to facilitate the placement of the orifice plate, and the second hand position is used to facilitate the pulling of the second plate.

[0052] The working principle of the utility model is as follows:

[0053] When in use, align the axial hole of the orifice plate 3 with the positioning shaft and place it in the cavity, rotate the clamping claw 4 to press the orifice plate 3, a lock shaft hole is pre-opened at the position where the door lock is installed on the cabin door body, and the end of the positioning shaft 13 located on the back of the first plate is aligned with the lock shaft hole on the door body. Place the first plate 1 on the cabin door body, determine the horizontality of the edge of the first plate, and then adsorb the first plate 1 on the door body under negative pressure. Pull the second plate 2 until the spring steel ruler displays a suitable reading and fix the second plate under negative pressure, and punch holes according to the positions of all positioning holes.
