Description

Horizontal Stakeout Device

The present invention particularly relates to a horizontal layout device, and particularly relates to a technical improvement of a horizontal layout device used in water and electricity engineering and decoration engineering.

During plumbing and decoration projects, the layout process is performed. Part of the layout process is to confirm the number of electrical accessories such as sockets and switches, as well as the locations where they are to be installed. During the layout process, the correct locations of the sockets and switches to be installed will be marked on the wall or other places where the sockets and switches are to be installed so that the subsequent opening and installation can be smooth.

It is known that a hole setting board is placed on the wall at the location where the socket or switch is to be installed to draw the cutting line. In order to confirm whether the hole setting board is kept horizontal, a level ruler is purchased separately and placed on the hole setting board to observe whether the hole setting board is placed horizontally. This method not only increases the cost, but also requires holding the level ruler in one hand and the hole setting board in the other hand for horizontal calibration, resulting in the inconvenience of drawing the cutting line and confirming the horizontal placement of the hole setting board at the same time, which makes setting out inconvenient.

Therefore, it is necessary to provide a novel and advanced horizontal layout device to solve the above-mentioned problems.

The main purpose of the present invention is to provide a horizontal layout device, which can be combined with a plurality of horizontal measurement units to assist in accurately judging the installation level during the installation of electrical accessories.

To achieve the above-mentioned purpose, the present invention provides a horizontal layout device, comprising: a body, which includes a mounting through hole, a first slot and a second slot, the mounting through hole penetrates the body in a thickness direction of the body, the mounting through hole is arranged between the first slot and the second slot, the first slot is perpendicular to the second slot, the first slot is used to install a first horizontal measurement unit, and the second slot is used to install a second horizontal measurement unit.

The following examples are only used to illustrate possible implementations of the present invention, but they are not intended to limit the scope of protection of the present invention. The "one" or "at least one" before the terms mentioned in the text does not limit the quantity. It can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be explained first.

Please refer to Figures 1 to 3, which show a first preferred embodiment of the present invention. The horizontal sample placing device 1 of the present invention includes a body 10.

The body 10 includes a mounting through hole 11, a first slot 20 and a second slot 30. The mounting through hole 11 penetrates the body 10 in a thickness direction D of the body 10. The mounting through hole 11 is disposed between the first slot 20 and the second slot 30. The first slot 20 is perpendicular to the second slot 30. The first slot 20 is used to mount a first horizontal measuring unit 60, and the second slot 30 is used to mount a second horizontal measuring unit 70. The horizontal layout device 1 further includes the first horizontal measuring unit 60 and the second horizontal measuring unit 70. The first horizontal measuring unit 60 is (detachably) mounted in the first slot 20, and the second horizontal measuring unit 70 is (detachably) mounted in the second slot 30. The first horizontal measuring unit 60 is perpendicular to the second horizontal measuring unit 70. In this way, multiple level measuring units (first and second level measuring units 60, 70) are combined to assist in accurately judging the level of installation during the installation of electrical accessories (such as single/double sockets, single/double switches, switch panels or junction boxes, etc.).

In addition, the first horizontal measuring unit 60 and the second horizontal measuring unit 70 are used as dual horizontal measuring units to determine the horizontal positions of multiple angles, and the horizontal placement device 1 can also be set up and used at multiple angles (horizontally or vertically).
