[0032] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] Example:

[0034] like Figure 1 to Figure 2 As shown, in order to solve the above problems, this embodiment discloses a quick locator for installing a water heater, comprising:

[0035] A first positioning plate 10, on which a pair of mounting grooves 100 and a pair of positioning members 101 are provided, the mounting grooves 100 are provided on both sides of the first positioning plate 10, the positioning members 101 are matched with the mounting grooves 100, and are slidably connected with the first positioning plate 10, and the positioning members 101 are provided with marking holes 102, and the positioning members 101 are used to determine the position of the mounting holes on the water heater;

[0036] A second positioning plate 20, wherein a limiting slide groove 200 is provided at the lower end of the second positioning plate 20, and a positioning hole 201 for determining the flue hole on the water heater is provided at the upper end;

[0037] A limiting rotating rod 103 is provided in the middle of the first positioning plate 10, and the limiting sliding groove 200 at the lower end of the second positioning plate 20 is sleeved on the limiting rotating rod 103 and is loosely matched with the limiting rotating rod 103. A fixing piece 104 for fixing the second positioning plate 20 is provided on the limiting rotating rod 103, and the fixing piece 104 is matched with the limiting rotating rod 103.

[0038] When the utility model is used, the water heater can be placed on the ground or on a table, and then the positioning member 101 on the first positioning plate 10 is moved to quickly complete the positioning of the installation hole on the water heater, and it is only necessary to align the line hole 102 on the positioning member 101 with the installation hole on the water heater; then the second positioning plate 20 is moved to make the positioning hole 201 on the second positioning plate 20 correspond to the flue hole on the water heater, and the position of the flue hole on the water heater can be quickly determined, and then the second positioning plate 20 is fixed by the fixing member 104, and the utility model is placed on the wall where the water heater needs to be installed, and a circle is drawn at the position corresponding to the line hole 102 and the positioning hole 201 by a line drawing pen, and the position of the installation hole and the flue hole required by the water heater on the wall can be quickly determined. The problem of cumbersome installation process and low installation efficiency when installing the current water heater is solved.

[0039] The limiting slide groove 200 at the lower end of the second positioning plate 20 is sleeved on the limiting rotating rod 103 and is clearance-matched with the limiting rotating rod 103, that is, the lower end of the second positioning plate 20 is rotationally matched and slidably matched with the limiting rotating rod 103, so that the second positioning plate 20 can slide and rotate.

[0040] The limiting rotating rod 103 is fixedly connected to the first positioning plate 10 .

[0041] like Figure 6 to Figure 7 As shown, in order to facilitate the rapid installation and disassembly of the positioning member 101 and the sliding of the positioning member 101, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the positioning member 101 includes a positioning slider 105 and a limiting plug 106. The positioning slider 105 is slidably installed on the first positioning plate 10. The positioning slider 105 is provided with an installation window 107 that is arranged in conjunction with the installation slide groove 100. The installation window 107 passes through the positioning slider 105; one end of the limiting plug 106 is a plug-in end, and the other end is a clamping end. The plug-in end of the limiting plug 106 can pass through the installation window 107 and be inserted into the installation slide groove 100, and is slidably connected to the installation slide groove 100. The drawing hole 102 is provided on the limiting plug 106 and passes through the limiting plug 106.

[0042] like Figure 7 As shown, preferably, a pair of limit installation grooves 108 are provided on the positioning slider 105, and the limit installation grooves 108 are arranged on both sides of the installation window 107, and are matched with the two sides of the clamping end of the limit plug block 106. The two sides of the clamping end of the limit plug block 106 can be inserted into the limit installation grooves 108 and clamped with the limit installation grooves 108.

[0043] like Figure 5As shown, preferably, the positioning slider 105 is provided with a mounting groove 109, the mounting groove 109 is arranged in cooperation with the first positioning plate 10, sliding protrusions 110 are provided on the inner walls on both sides of the mounting groove 109, and the first positioning plate 10 is provided with a sliding limit groove 111 arranged in cooperation with the sliding protrusion 110, and the positioning slider 105 is slidably connected to the first positioning plate 10 through the cooperation between the sliding protrusion 110 and the sliding limit groove 111.

[0044] During installation, first, the sliding protrusion 110 in the mounting groove 109 on the positioning slider 105 corresponds to the sliding limit groove 111 on the first positioning plate 10 and then snaps it in, so that the positioning slider 105 slides to cooperate with the mounting slide groove 100 on the first positioning plate 10, and then the plug-in end of the limiting plug 106 is inserted into the mounting slide groove 100 through the mounting window 107, and at the same time, the two sides of the clamping end of the limiting plug 106 are snapped into the limiting mounting groove 108 to complete the installation of the positioning member 101.

[0045] The limiting insert 106 plays a limiting role, so that the positioning slide block 105 can only slide back and forth at the installation slide groove 100 on the first positioning plate 10.

[0046] like Figure 6 As shown, in order to facilitate locking the positioning slider 105, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a locking bolt 112 is provided at the bottom of the positioning slider 105. One end of the locking bolt 112 passes through the bottom of the positioning slider 105 and abuts against the first positioning plate 10, which is used to fix the positioning slider 105. The locking bolt 112 is threadedly connected to the positioning slider 105.

[0047] After the position of the mounting hole on the water heater is determined, the positioning slider 105 can be fixed by tightening the locking bolt 112 to prevent the positioning slider 105 from continuing to slide and causing misalignment.

[0048] In order to facilitate determination of whether the first positioning plate 10 is horizontal and avoid tilted installation of the water heater, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a bubble level 113 is provided on the top of the positioning slider 105.

[0049] The bubble level 113 may be any bubble level 113 in the prior art that can realize the functions of the present invention.

[0050] like Figure 8As shown, in order to facilitate the installation or replacement of the bubble level 113, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the bubble level 113 is fixedly installed on the top of the positioning slider 105 through a connecting piece 114. The connecting piece 114 includes an elastic clamping portion 115, a plug-in portion 116 and an elastic connecting band 117. The two ends of the elastic connecting band 117 are respectively fixedly connected to the elastic clamping portion 115 and the plug-in portion 116. The top of the positioning slider 105 is provided with an insertion groove 118 cooperating with the plug-in portion 116 and a plug-in groove 119 cooperating with the elastic clamping portion 115.

[0051] When in use, the bubble level 113 can be fixedly installed on the top of the positioning slider 105 through the connecting piece 114. When replacement is needed, it is only necessary to press the elastic clamp head 115 to disengage the elastic clamp head 115 from the plug-in slot 119, and then the connecting piece 114 can be removed to complete the disassembly of the bubble level 113.

[0052] Preferably, the elastic clamping portion 115 includes a pair of elastic arms 124 and a clamping joint 125 , one end of the elastic arm 124 is fixedly connected to the elastic connecting band 117 , and the clamping joint 125 is arranged at the other end of the elastic arm 124 .

[0053] Preferably, the insertion slot 119 includes a vertical slot 126 cooperated with the elastic arm 124 and a matching slot 127 cooperated with the card connector 125 , and the elastic arm 124 and the vertical slot 126 are clearance-matched.

[0054] By pressing the clamping joint 125 , the elastic arm 124 can be deformed in the vertical groove 126 , so that the clamping joint 125 is disengaged from the matching groove 127 , thereby releasing the limit of the connecting member 114 , and the connecting member 114 can be removed.

[0055] like Figure 1 As shown, in order to more conveniently fix the second positioning plate 20, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the fixing member 104 includes a gasket 120 and a locking rotary sleeve 121, and the gasket 120 and the locking rotary sleeve 121 are sequentially inserted into the limiting rotating rod 103, and the locking rotary sleeve 121 is provided with an internal thread, and the limiting rotating rod 103 is provided with an external thread that cooperates with the internal thread, and the locking rotary sleeve 121 is threadedly connected to the limiting rotating rod 103.

[0056] When in use, the second positioning plate 20 can be quickly fixed by the locking sleeve 121 and the gasket 120. When the second positioning plate 20 needs to be moved or disassembled, the locking sleeve 121 and the gasket 120 are removed to quickly complete the disassembly of the second positioning plate 20.

[0057] like Figure 3As shown, in order to facilitate keeping the second positioning plate 20 perpendicular to the first positioning plate 10, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a pair of detachable limit mounting blocks 122 are provided on the first positioning plate 10, and the limit mounting blocks 122 are respectively inserted on both sides of the limit rotating rod 103. There is an installation gap between the limit mounting blocks 122 and the limit rotating rod 103 for limiting the rotation of the second positioning plate 20, and the lower end of the second positioning plate 20 can be respectively inserted into the installation gap.

[0058] like Figure 4 As shown, preferably, the first positioning plate 10 is provided with a pair of plug-in ports 128 that cooperate with the limiting mounting block 122 , and one end of the limiting mounting block 122 can be inserted into the plug-in port 128 to be plugged with the first positioning plate 10 .

[0059] When in use, the limiting mounting block 122 is used to limit the rotation of the second positioning plate 20, so that the second positioning plate 20 can always remain perpendicular to the first positioning plate 10, thereby preventing the water heater from tilting during installation.

[0060] Generally, the flue holes on the water heater are located on an axis perpendicular to the axis of the mounting hole. Therefore, the limit mounting block 122 is generally plugged into the plug port 128. However, it is possible that a processing error may cause the flue hole of the water heater to deviate. In this case, the limit mounting block 122 needs to be removed.

[0061] like Figure 2 As shown, preferably, a pair of anti-skid pads 123 for anti-skid is provided on the first positioning plate 10, and the anti-skid pads 123 are respectively installed on both sides of the end of the first positioning plate 10 that contacts the wall.

[0062] The anti-skid pad 123 can be a flexible rubber pad in the prior art, with a plurality of grooves arranged on the surface, so as to increase the friction between the anti-skid pad 123 and the wall, thereby playing an anti-skid role and facilitating the operator to draw lines.

[0063] In order to more quickly determine the position of the mounting hole, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the first positioning plate 10 is provided with scale lines extending from the middle to both ends.

[0064] During use, since the positions of the two mounting holes on the water heater are generally symmetrical, after setting the scale line, it is only necessary to align the mounting holes on one side first, and then quickly move the positioning member 101 according to the scale to quickly complete the confirmation of the mounting hole position.

[0065] Since the first positioning plate 10 and the second positioning plate 20 are connected in a detachable manner, they can be disassembled when carried, thereby having the advantage of being easy to carry.

[0066] After using the utility model, the installation process of the water heater can be effectively shortened, thereby reducing the installation time of the water heater, thereby solving the problems of complicated installation process and low installation efficiency during the installation of the current water heater.

[0067] Compared with the traditional installation, the installation time of the water heater by using the utility model is shortened from 65 minutes to 50 minutes, and only one operator is needed to complete it, while the traditional one requires the cooperation of two people to complete it.

[0068] Working principle of this utility model:

[0069] When the utility model is in use, the water heater can be placed on the ground or on a table, and then the positioning piece 101 on the first positioning plate 10 is moved to quickly complete the positioning of the installation hole on the water heater, and it is only necessary to align the marking hole 102 on the positioning piece 101 with the installation hole on the water heater; then, by moving the second positioning plate 20, the positioning hole 201 on the second positioning plate 20 corresponds to the flue hole on the water heater, and the position of the flue hole on the water heater can be quickly determined, and then after fixing the second positioning plate 20 by the fixing piece 104, the utility model is placed on the wall where the water heater needs to be installed, and a circle is drawn at the position corresponding to the marking hole 102 and the positioning hole 201 by a marking pen, and the position of the installation hole and the flue hole required for the water heater on the wall can be quickly determined.

[0070] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
