Description

Portable Field Workbench Box Utilizing Magnetic Limitation

technical field

The invention relates to a surveying and mapping tool, in particular to a portable field workbench box utilizing magnetic positioning.

Background technique

After the known toolbox with support is opened at present, adopt support bar or rope to pull and fix the box cover. This mode is unfavorable for adjusting the angle of box cover, and the stability of box cover is also very poor, and the support or dragline between box body and box cover also has very big hindrance to utilizing box body to work.

Contents of the invention

Aiming at the deficiencies in the prior art, the invention provides a portable field workbench box utilizing magnetic positioning.

The object of the present invention is achieved in this way: a portable field workbench box utilizing magnetic positioning, comprising a box body, a case cover, a back frame, an inner back frame, a rear bracket, and a front bracket, wherein the box body There is a box cover on the top, and a back frame, a rear bracket, and a front bracket on the bottom; metal sheets are fixed on the box cover; an inner back frame is arranged inside the back frame, and an upper link is arranged on the inner back frame. A permanent magnet is arranged in the middle of the upper connecting rod; an inner rear bracket is arranged in the rear bracket, a rear bracket connecting rod is fixed on the inner rear bracket, and a steel bar is arranged on the rear bracket connecting rod; a front stand.

The metal sheet is magnetic and can be attracted by the permanent magnet, and the steel strip is magnetic and can be attracted by the second permanent magnet.

The steel bar is provided with a lower tooth surface, and the second permanent magnet is provided with an upper tooth surface, and the size and spacing of the tooth lines on the lower tooth surface match the size and spacing of the tooth lines on the upper tooth surface.

The case cover, the back frame, the rear bracket and the front bracket can rotate within a certain range, the length of the back frame, the rear bracket and the front bracket is less than the length of the inner back frame, the inner rear bracket and the inner front bracket, the back frame, the rear bracket and the inner front bracket The inner back frame, the inner rear bracket and the inner front bracket in the front bracket can be pulled or fixed respectively in the back frame, the rear bracket and the front bracket, and the back frame, the rear bracket and the front bracket can be folded under the casing.

Expand the front bracket, rear bracket and back bracket respectively, loosen the positioning bolts respectively, and pull out the inner back bracket, inner rear bracket and inner front bracket respectively; loosen the positioning bolts respectively, and make the inner back bracket, inner rear bracket and inner back bracket The front brackets are positioned separately; the steel bar is placed on the second permanent magnet, and the magnetism forces the two to stick together. Since the tooth pattern of the upper tooth surface matches the tooth pattern of the lower tooth surface, the two cannot move in parallel, so that the whole The bracket is in a stable state.

When the case cover is opened and leans against the inner back frame, the permanent magnet contacts the metal sheet, and the magnetism forces the two to stick together, so that the case cover is in a stable state.

The present invention adopts above-mentioned design, and its advantage is:

1) The fixing method of permanent magnet and metal sheet is adopted, so that the toolbox cover can be directly leaned against the inner back frame and fixed by the permanent magnet, which eliminates the use of support rods or cables between the traditional toolbox and the box cover. The obstruction of placing the drawing board makes it more convenient to use the cabinet for drawing or drawing;

2) The permanent magnet and the steel bar are attracted by the fixed method. Since the displacement adjustment between the permanent magnet and the steel bar can be very precise, the positioning of the back frame is more stable, and the adjustment of the inclination angle is more random; the overall installation and disassembly are also more convenient. Faster and more convenient.

Detailed ways

Below, the present invention will be described in detail with reference to the drawings and embodiments.

Fig. 1 - Fig. 3 is an embodiment of the present invention, and as shown in the figure , a kind of portable field workbench box utilizing magnetic limit, comprises box body 10, box cover 11, back frame 20, inner back frame 21, rear Bracket 30, front bracket 40, it is characterized in that, described box body 10 is provided with box cover 11, is provided with back frame 20, rear bracket 30, front bracket 40 below; Described box cover is fixedly provided with metal plate 12; An inner back frame 21 is arranged in the back frame 20, an upper link 22 is arranged on the inner back frame 21, and a permanent magnet 23 is arranged in the middle of the upper link 22; The rear bracket 31 is fixed with a rear bracket connecting rod 32 , and the rear bracket connecting rod 32 is provided with a steel bar 33 ; the front bracket 40 is provided with a front bracket 41 .

The metal sheet 12 is magnetic and can be attracted by the permanent magnet 23 , and the steel strip 33 is magnetic and can be attracted by the second permanent magnet 25 .

The steel bar 33 is provided with a lower tooth surface 34 , and the second permanent magnet 25 is provided with an upper tooth surface 26 .

Case cover 11, back frame 20, rear support 30 and front support 40 can rotate within a certain range, and the length of back frame 20, rear support 30 and front support 40 is less than inner back frame 21, inner rear support 31 and inner front support The length of 41, the inner back frame 21 in the back frame 20, the rear frame 30 and the front frame 40, the inner rear frame 31 and the inner front frame 41 can be pulled or pulled in the back frame 20, the rear frame 30 and the front frame 40 respectively. Being fixed, the back frame 20 , the rear frame 30 and the front frame 40 can be folded under the box body 10 .
