Description

Technical Field

[0001] The utility model relates to the technical field of box body processing, in particular to a marking tool for determining the center of a box body by using concave and convex positions. Background Art

[0002] In the industry, in order to protect some delicate workpieces or equipment that cannot withstand strong collisions during transportation, a box that meets the size of the workpiece or equipment to be protected is required. In order to ensure the stability of the box structure, a concave and convex surface is set on the box.

[0003] In order to better protect the workpiece or equipment, that is, to reduce the probability of damage caused by shaking and collision in the box, it is necessary to add spacer blocks and other limiting structures to the box. At the same time, in order to ensure the limiting function of spacer blocks and other limiting structures, it is necessary to install spacer blocks and other limiting structures according to the size of the workpiece or equipment to be protected. To install the limiting structure according to the size, it is necessary to draw the center line on the corresponding side of the box, and then accurately install the corresponding structure based on the center line.

[0004] The existing method of drawing the center line of the corresponding side of the box requires the staff to measure the width of the corresponding side of the box, then determine the size of the center position of the box after calculation, and then use a ruler to mark it. After that, the above steps are repeated to obtain multiple center points, and finally the center points are connected to obtain the center line. However, this method will result in poor center line accuracy due to the number of measurements and inaccurate connection of points, and it will also cause the staff to have a large workload in determining the center line. Utility Model Content

[0005] The utility model aims to provide a marking tool for determining the center of a box body by means of concave and convex positions, so as to assist workers in quickly and accurately drawing the center line on the corresponding side surface of the box body for use as a reference.

[0006] In order to solve the above technical problems, the specific solution adopted by the utility model is:

[0007] A marking tool for determining the center of a box body by means of concave and convex positions, comprising two parallel transverse plates, a marking plate arranged between the two transverse plates, and a marking hole opened on the marking plate and having a center aligned with the center of the transverse plate;

[0008] Both ends of the transverse plate are provided with fixed-point columns that slide along the length direction of the transverse plate. The two fixed-point columns are hinged with the central linkage mechanism provided on the transverse plate, so that the two groups of two fixed-point columns are symmetrical with the midpoint of the transverse plate as the symmetry point. The ends of the two fixed-point columns that are away from the transverse plate are used for sliding cooperation with the concave and convex positions that are symmetrical in the center of the box body.

[0009] The central linkage mechanism comprises a central slide plate which slides vertically at the center of the transverse plate, and a linkage hinge plate which is connected to a fixed point column is connected at the center of the end of the central slide plate.

[0010] As a further optimization of the marking tool for determining the center of the box body by the concave-convex position of the utility model, an insertion cavity is opened at one end of the fixed point column facing the concave-convex position, and an adaption block is clamped in the insertion cavity.

[0011] As a further optimization of the scribing tool for determining the center of the box body by the concave and convex positions of the utility model, the end of the adaption block away from the box body is magnetically connected to the magnetic attraction block fixed on the inner wall of the insertion cavity.

[0012] As a further optimization of the marking tool for determining the center of the box body by the concave and convex positions of the utility model, an elastic ring for clamping the marking pen is provided in the marking hole.

[0013] As a further optimization of the utility model, a marking tool for determining the center of the box body by concave and convex positions is fixed with a sliding block at one end of the fixed point column facing the horizontal plate. The sliding block slides in cooperation with a sliding groove provided in the length direction of the horizontal plate. The sliding block passes through the sliding groove and is hinged to the end of the linked hinge plate.

[0014] As a further optimization of the scribing tool for determining the center of the box body by the concave and convex positions of the utility model, the sliding block and the sliding groove are both dovetail-shaped.

[0015] As a further optimization of the marking tool for determining the center of the box body by the concave and convex positions of the utility model, the central sliding plate is hinged to the linked hinge plate and passes through the transverse plate.

[0016] As a further optimization of the scribing tool for determining the center of the box body by the concave and convex positions of the utility model, a blocking plate for limiting the separation of the central slide plate from the transverse plate is provided at the end of the central slide plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model increases the stability of the box structure by setting symmetrical concave and convex positions with the center of the corresponding side of the box as the reference, thereby improving the protection function of the protected workpiece or equipment. At the same time, a fixed-point column that slides with the concave and convex positions of the box is set to utilize the symmetry of the concave and convex positions of the box with the center of the box as the reference, so that the corresponding fixed-point column is also symmetrical with the center of the box as the symmetry point, and then the center of the horizontal plate that slides with the fixed-point column is overlapped with the symmetry center of the fixed-point column through the center linkage mechanism. When it is necessary to draw a center line on the corresponding side of the box as a reference for use, the marking hole opened on the marking plate and the center of the circle aligned with the center of the horizontal plate can be used to cooperate with the marking pen to quickly and accurately draw the center line. Thereby assisting the staff to use the center line as a reference to quickly determine the installation position of the limiting structure such as the pad block for accurate installation.

[0019] As a further optimization of the utility model, by providing a snap-on adaptation block, it is convenient for the corresponding staff to select different adaptation blocks for snap-on use with the fixed-point columns according to the different concave and convex positions, thereby improving the universality of use to a certain extent.

DETAILED DESCRIPTION

[0023] The utility model includes a fixed point column 2 that is slidably matched with a symmetrically arranged concave and convex position 101, so that the fixed point column 2 is symmetrical with the symmetry center of the concave and convex position 101 as a reference. At the same time, through a transverse plate 3 slidably connected to the fixed point column 2 and a center linkage mechanism 6 arranged on the transverse plate 3, the symmetry center of the fixed point column 2 coincides with the center of the transverse plate 3. Therefore, the center line can be quickly and accurately drawn with the connection hole 4 whose center is aligned with the center of the transverse plate 3.

[0024] like Figure 1 As shown, the concave-convex position 101 set on the box body 1 is symmetrical with respect to the center of the box body 1, thereby improving the structural stability of the box body 1, thereby improving the protection function of the protected workpiece or equipment, and enabling the symmetry center of the concave-convex position 101 to coincide with the midpoint of the box body 1.

[0025] like Figure 1 and Figure 2 As shown, an insertion cavity 201 is provided at one end of the fixed-point column 2 facing the concave-convex position 101, and an adaption block 202 is clamped in the insertion cavity 201. By replacing different adaption blocks 202, it is possible to adapt to concave-convex positions 101 of different widths, and then connect with the corresponding concave-convex position 101 to limit the position of the fixed-point column 2, so that the corresponding two fixed-point columns 2 are symmetrical about the symmetry center of the concave-convex position 101, that is, the corresponding two fixed-point columns 2 are symmetrical with the midpoint of the box body 1 as the reference. The end of the adaption block 202 that passes through the insertion cavity 201 and faces the concave-convex position 101 is a smooth surface, so that it is convenient for the staff to make the fixed-point column 2 slide on the box body 1 under the restriction of the concave-convex position 101. And the adaption block 202 is magnetically connected to the magnetic suction block 203 fixed in the insertion cavity 201, thereby further improving the stability of the connection between the adaption block 202 and the fixed-point column 2.

[0026] The two corresponding fixed-point columns 2 are fixedly connected to the sliding block 301, and the sliding block 301 is slidably connected to the sliding groove 302 provided in the length direction of the transverse plate 3. The sliding block 301 and the sliding groove 302 are both dovetail-shaped. There are two transverse plates 3, and the two transverse plates 3 are arranged in parallel. The opposite surfaces of the two transverse plates 3 are fixedly connected to the two ends of the marking plate 5. The arrangement of the two transverse plates 3 and the marking plate 5 can stabilize the relative position of the fixed-point columns 2, and at the same time, it is convenient for the staff to hold and use, and it is convenient for the staff to push. The marking plate 5 is provided with a marking hole 4 whose center is aligned with the center of the transverse plate 3, and an elastic ring is fixed in the marking hole 4. The marking hole 4 can facilitate the staff to pass the corresponding marking pen through, and then position the corresponding marking pen on the marking plate 5 through the elastic ring fixed in the marking hole 4, and at the same time, the circular marking pen tip coincides with the center of the marking hole 4. Thereby, the tip of the marking pen coincides with the center of the corresponding side surface of the box body 1 , thereby drawing a more accurate center line on the corresponding side surface of the box body 1 .

[0027] The central linkage mechanism 6 includes a central slide plate 601 that slides in the center of the transverse plate 3. Both end surfaces of the central slide plate 601 are fixedly connected with blocking plates 603. The setting of the blocking plates 603 can maintain the stability of the connection between the transverse plate 3 and the central slide plate 601. A linkage hinge plate 602 is hinged at the center of the end of the central slide plate 601. The end of the linkage hinge plate 602 that is away from the central slide plate 601 is hinged to the sliding block 301 passing through the sliding groove 302, thereby making the symmetry center of the two fixed-point columns 2 coincide with the center of the transverse plate 3. The hinged side of the central slide plate 601 and the linkage hinge plate 602 passes through the transverse plate 3, so that the central slide plate 601 can make the two linkage hinge plates 602 in a straight line, which is convenient for the staff to use on the symmetrical concave and convex positions 101 with different distances, and at the same time, the corresponding two fixed-point columns 2 can be unfolded to the maximum to maintain the universality of use.

[0028] When the fixed-point column 2 is connected to the concave-convex position 101 and is restricted in position, the center of the horizontal plate 3 can be made to coincide with the symmetric center of the concave-convex position 101, i.e., the center of the corresponding side of the box body 1, through the setting of the center linkage mechanism 6, and the center of the circle of the marking hole 4 can also coincide with the center of the corresponding side of the box body 1. Then the two horizontal plates 3 can be pushed to move. In the process of the two horizontal plates 3 moving, the corresponding four fixed-point columns 2 will slide on the box body 1 under the restriction and guidance of the concave-convex position 101, and then the marking plate 5, the marking hole 4 and the marking pen will be driven to move synchronously, and then the marking pen will be used to draw the corresponding center line on the corresponding side of the box body 1. Next, the staff can use the center line as a reference to determine the installation position of the limiting structure such as the pad block, thereby improving the work efficiency of the staff in installing the limiting structure such as the pad block to a certain extent.
