[0042] In the detailed disclosure below, reference is made to the accompanying drawings, which are characterized by a portion of them as illustrations of specific embodiments that can be implemented, and fully describe these embodiments. In order to make the technical solution of the utility model more clear and clear to those skilled in the art, the implementation method described below is not limited to this. The utility model is further described in detail below in conjunction with the embodiments and drawings.

[0043] The utility model provides a fixing device for marking objects, such as Figure 1-Figure 14As shown, it is used to position the marker at a specified position of the carrier, and the fixing device used for the marker includes a positioning mold 1 and a measuring mechanism 2. A limit cavity 12 is provided on the positioning mold 1. The shape of the limit cavity 12 is adapted to the shape of the marker and is used to accommodate the marker and limit the marker. The limit cavity 12 cooperates with the marker with a small gap. The measuring mechanism 2 is connected to the positioning mold 1. The measuring mechanism 2 includes a first measuring unit 21 arranged along a first direction and a second measuring unit 22 arranged along a second direction. The first direction and the second direction are arranged at an angle. The first measuring unit 21 is used to measure the distance between the positioning mold 1 and the first position to be measured on the carrier along the first direction, and the second measuring unit 22 is used to measure the distance between the positioning mold 1 and the second position to be measured on the carrier along the second direction.

[0044] like Figure 3 and Figure 4 As shown, the fixing device applied to the marker limits the marker through the positioning mold 1, and limits the marker in the limiting cavity 12 that matches its shape. The limiting cavity 12 is set on the positioning mold 1, and is open at both ends, so that the marker can be put into the limiting cavity 12 from one end opening, and pass through the other end opening to connect the marker with the carrier. The setting of the limiting cavity 12 is suitable for markers of various shapes and has wide applicability. At the same time, the positioning mold with a more standard shape is easier to observe and locate by naked eyes compared with the marker with irregular shape. The limiting cavity 12 and the marker with a small gap fit, and the gap between the limiting cavity 12 and the marker can be 0.2mm~2mm, which can limit the marker more accurately to prevent the marker from shifting in the limiting cavity 12, and will not cause the marker to shift after the positioning mold 1 is removed.

[0045] like Figure 3 and Figure 4 As shown, the measuring mechanism 2 includes a first measuring unit 21 for measuring the length along a first direction and a second measuring unit 22 for measuring the length along a second direction. The distance between the positioning mold 1 and a position to be measured on the carrier, i.e., the first position to be measured, is measured along the first direction, and the distance between the positioning mold 1 and another position to be measured on the carrier, i.e., the second position to be measured, is measured along the second direction. The position of the positioning mold 1 is located by the lengths in two different directions. When the angle between the first direction and the second direction is determined, the positioning is performed by the angle and the length. The accuracy is high, the needs of different carriers can be met, and the applicable scenarios are wider.

[0046] It can be understood that the position of the carrier to be measured is a position with a certain reference near the installation position of the marker. The position to be measured can be the edge line of the carrier or a certain reference line on the carrier.

[0047] This embodiment takes a cabinet as an example, and the position to be measured may be the outer edge of the cabinet, a glass edge, a handle, an air vent, etc., as long as it has a certain reference for measuring the distance.

[0048] The fixing device used for the marker is used in combination with the positioning mold 1 and the measuring mechanism 2, which can not only ensure the accuracy of the installation position of the marker, but also ensure the accuracy of the installation direction of the marker itself, so as to achieve the effect of accurate and non-offset installation position of the marker.

[0049] In one possible implementation, the angle between the first direction and the second direction is fixed or adjustable.

[0050] It can be understood that when the angle between the first direction and the second direction is fixed, the first measuring unit 21 and the second measuring unit 22 can be fixedly connected, and the structure is more stable. Further, when the angle between the first direction and the second direction is 90°, the measurement can be performed along two directions perpendicular to each other, which has a strong reference and can be applied to carriers of most shapes, especially carriers with regular shapes.

[0051] It can be understood that when the angle between the first direction and the second direction is adjustable, the first measuring unit 21 and the second measuring unit 22 can be rotatably connected. The first measuring unit 21 and the second measuring unit 22 are connected by a rotating shaft. The angle between the two can be adjusted by rotation. Measurements can be performed from different directions by adjusting a suitable angle, which is suitable for carriers with irregular shapes.

[0052] For example, if the carrier is of irregular shape and has no smooth edge for reference near the installation position of the marker, two positions to be measured that can provide reference can be selected on the carrier by adjusting the angle between the first direction and the second direction, which has wider applicability.

[0053] Furthermore, an angle fixing member may be provided to fix the positions of the first measuring unit 21 and the second measuring unit 22 after adjusting the angle, so as to ensure that the angle does not change during the measurement process. The fixing member may be a bolt or other component that can meet the requirement of fixing the angle.

[0054] In one possible implementation, Figure 2 As shown, the positioning mold 1 further includes a plate 11 and a receiving groove 13. The plate 11 includes a contact surface for contacting the carrier, and the surface shape of the marker at the carrier installation location is adapted to the shape of the contact surface.

[0055] like Figure 2 , Fig. 9 and Fig.12As shown, the receiving groove 13 is formed on the plate 11 , and the receiving groove 13 matches the shape of the measuring mechanism 2 for accommodating the measuring mechanism 2 . The receiving groove 13 and the measuring mechanism 2 placed in the receiving groove 13 are both located on the side of the contact surface away from the carrier.

[0056] It is understandable that if Figure 5 and Figure 6 As shown, a portion of the measuring mechanism 2 in the edge projection area of ​​the plate 11 is located in the receiving groove 13, and the receiving groove 13 is separated from the carrier. At the same time, the side of the measuring mechanism 2 facing the carrier can be flush with the contact surface or located on the side of the contact surface away from the carrier. That is, when the contact surface of the plate 11 fits with the carrier, the measuring mechanism 2 can be in contact with or separated from the carrier, and the measuring mechanism 2 does not protrude from the contact surface to ensure that the plate 11 can fit with the carrier, so as to prevent the marker from leaving the limiting cavity 12 and contacting the carrier, and to ensure that when the marker is in contact with the carrier, the standard is always located in the limiting cavity 12.

[0057] In one possible implementation, Fig. 9 and Fig.10 As shown, the first measuring unit 21 includes a first measuring ruler 211 , the second measuring unit 22 includes a second measuring ruler 221 , and the receiving groove 13 includes a first groove 131 and a second groove 132 . The first groove 131 is used to accommodate the first measuring ruler 211 , and the second groove 132 is used to accommodate the second measuring ruler 221 .

[0058] Furthermore, the accommodating groove 13 further includes a third groove 133 , and the third groove 133 is used to accommodate the second measuring ruler 221 .

[0059] like Figure 1 and Figure 3 As shown, the directions of the first measuring ruler 211 and the second measuring ruler 221 can be adjusted to adjust the positions to be placed in the receiving groove 13. It can be understood that the width of the receiving groove 13 is slightly larger than the width of the measuring ruler, and a small gap is provided between the groove and the measuring ruler to reduce the space in which the measuring ruler can move in the groove and reduce the measurement error.

[0060] It can be understood that by providing the first groove 131 along the first direction for accommodating the first measuring ruler 211, and providing the second groove 132 and the third groove 133 along the second direction for accommodating the second measuring ruler 221, by adjusting the direction of the measuring mechanism 2, it is adjusted whether to place the measuring mechanism 2 in the first groove 131 and the second groove 132, or to place the measuring mechanism 2 in the first groove 131 and the third groove 133. Thus, the direction of measuring the length based on the positioning mold 1 can be adjusted, which is more suitable for the need of installing markers at different positions of the carrier and has wider applicability.

[0061] In one possible implementation, Fig.11and Fig.12 As shown, the first measuring unit 21 includes a first measuring ruler 211, the second measuring unit 22 includes a second measuring ruler 221 and a third measuring ruler 222, and the accommodating groove 13 includes a first groove 131, a second groove 132 and a third groove 133, the first groove 131 is used to accommodate the first measuring ruler 211, the second groove 132 is used to accommodate the second measuring ruler 221, and the third groove 133 is used to accommodate the third measuring ruler 222.

[0062] It can be understood that, by providing the first groove 131 along the first direction for accommodating the first measuring ruler 211, the first measuring ruler 211 may protrude from the positioning mold 1 at one end, or both ends thereof. When both ends of the first measuring ruler 211 extend out of the first groove 131, the function of measuring the distances of two directions along the first direction can be achieved without adjusting the direction of the measuring mechanism 2.

[0063] like Fig.12 As shown, two measuring rulers along the second direction, namely, the second measuring ruler 221 and the third measuring ruler 222, can be provided, and the second measuring ruler 221 and the third measuring ruler 222 are relatively parallel to each other, so as to increase the positions to be measured of the carrier that can be used for measurement reference, and thus further reduce the error.

[0064] It can be understood that both ends of the accommodating groove 13 can be connected to the outside, and can be selected in both the first direction and the second direction, with wide adaptability.

[0065] In one possible implementation, Figure 2 and Figure 4 As shown, the bottom of the accommodating groove 13 is located in the same plane, that is, the first groove 131, the second groove 132 and the third groove 133 are all located in the same plane. At this time, the first measuring scale 211, the second measuring scale 221 and the third measuring scale 222 are all located in the same plane, which is more suitable for the situation where the position of the measuring scale is relatively fixed.

[0066] In one possible implementation, Fig.12 As shown, the bottoms of the accommodating grooves 13 are not located in the same plane, that is, the first groove 131, the second groove 132 and the third groove 133 are not located in the same plane. At this time, the first measuring scale 211, the second measuring scale 221 and the third measuring scale 222 are not located in the same plane, which is more suitable for the situation where the position of the measuring scale needs to be moved.

[0067] Further, such as Fig.12As shown, the second groove 132 and the third groove 133 are located in the same plane, and are located in a different plane from the first groove 131, that is, the second measuring ruler 221 and the third measuring ruler 222 are located in the same plane, and are located in a different plane from the first measuring ruler 211. At this time, the positions of the first measuring ruler 211, the second measuring ruler 221 and the third measuring ruler 222 will not affect each other's movement, and measurements can be performed in different directions of the first direction and the second direction, and a more appropriate position to be measured on the carrier can be selected.

[0068] In one embodiment, the first measuring unit 21 and the second measuring unit 22 can slide relative to each other, that is, the measurable length range and the measuring direction can be adjusted by sliding the first measuring unit 21 and the second measuring unit 22 while ensuring the directions of the two.

[0069] Furthermore, the second measuring ruler 221 and the third measuring ruler 222 can slide relative to the first measuring ruler 211, and the accommodating groove 13 can be set according to the movable range of the first measuring ruler 211, the second measuring ruler 221 and the third measuring ruler 222, so as to adjust the measurable length range and measuring direction, and select a more suitable position to be measured on the carrier.

[0070] In one possible implementation, Fig.12 and Fig.14 As shown, the positioning mold 1 also includes a baffle 14, which is disposed in the accommodating groove 13 and is used to limit the measuring mechanism 2 in the accommodating groove 13, and the baffle 14 is flush with the contact surface or is located on the side of the contact surface away from the carrier.

[0071] It can be understood that the measuring mechanism 2 is located in the receiving groove 13 , and can be positioned by the shapes of the measuring mechanism 2 and the receiving groove 13 , so that the measuring mechanism 2 is stably located in the receiving groove 13 .

[0072] The measuring mechanism 2 can also be confined in the accommodating groove 13 by a baffle 14 , and the baffle 14 and the positioning mold 1 can be fixedly connected or detachably connected.

[0073] In one possible implementation, the first measuring unit 21 and the second measuring unit 22 both include a ruler with a scale, and the ruler is a ruler, a measuring tape, or a combination of the two.

[0074] Among them, when the ruler is a ruler, the ruler is an integrally formed ruler or a foldable ruler, the structure of the ruler is more stable, and the accuracy of the measurement direction can be ensured by the shape of the ruler itself.

[0075] Among them, when the ruler is a tape measure, the tape measure has a certain elasticity and can be deformed, and can be suitable for measuring different carrier surface shapes, for example, when the carrier surface has depressions or protrusions that affect the ruler measurement.

[0076] In one possible implementation, the ruler is made of one of plastic, metal, alloy, fiberglass, wood, bamboo, and rubber.

[0077] In this embodiment, the ruler is made of plastic as an example. It is usually made of polymers, such as ABS plastic or polypropylene, and has the characteristics of being light, tough, wear-resistant, transparent, and waterproof. It is economical and suitable for lightweight measurement work.

[0078] In this embodiment, the ruler is made of metal as an example, which can be a hard metal, such as steel, which has the characteristics of durability, high precision, and corrosion resistance, and is suitable for occasions requiring high-precision measurement.

[0079] In this embodiment, the material of the ruler is alloy as an example, which can be stainless steel, aluminum alloy, etc. It is light, strong, and rust-proof, has high hardness and durability, and is suitable for measuring long or uneven surfaces.

[0080] In this embodiment, the material of the ruler is glass fiber, which has the characteristics of heat resistance, corrosion resistance and good insulation performance.

[0081] In this embodiment, the ruler is made of wood or bamboo as an example, which has the characteristics of being light and strong, having a good hand feel, and not easily scratching the operator when in use.

[0082] In this embodiment, the ruler is made of rubber as an example. Rubber has good elasticity and is mainly used to measure curved objects or carriers with uneven surfaces.

[0083] In one possible implementation, Fig.13 and Fig.14 As shown, the end of the ruler can be provided with an abutment 24 for abutting against the position to be measured, so that the scale on the measuring ruler is aligned with the position to be measured, which is convenient for fixing the position of the measuring ruler and reducing the error of naked eye observation, such as the outer edge of the carrier, the groove of the drawer, etc. The abutment 24 protrudes from the ruler and extends in the direction of the carrier, and the angle between the abutment 24 and the ruler can be 90°, which is more convenient for the abutment 24 to abut against the carrier.

[0084] In one possible implementation, Fig.13 and Fig.14 As shown, in the case where the ruler is a tape measure, the measuring mechanism 2 further includes a winder 23 , and at least a portion of the ruler is wound up in the winder 23 .

[0085] It is understandable that a reel 23 can be provided for storing the measuring tape, a shaft and a spring are provided in the reel, one end of the measuring tape is fixed on the shaft, and a part of the measuring tape is reeled on the shaft, and the spring is used to keep the part of the measuring tape reeled on the shaft in a tightened state. When in use, the end of the measuring tape exposed from the reel 23 is pulled outward, and after being released, the spring drives the shaft to rotate and reel the exposed part of the measuring tape on the shaft again.

[0086] Further, such as Fig.14 As shown, the winder 23 can be arranged on the side of the plate 11 away from the carrier, and a channel 15 for the tape measure to pass through can be opened on the plate 11 to make the tape measure closer to the contact surface, reduce the distance between the tape measure and the carrier, and reduce the error caused by the distance. The width of the channel 15 is greater than the width of the tape measure.

[0087] Compared with a ruler, a tape measure can greatly expand the range of measurement, reduce the space occupied, and can measure carriers with different surface unevenness. When the ruler is a tape measure, it can be made of steel or fiberglass, and can maintain the accuracy of the measurement direction after the tape measure is pulled out.

[0088] In one possible implementation, Figure 3 , Figure 7 and Figure 8 As shown, the fixing device applied to the marker further includes a horizontal calibration mechanism 3 , which is arranged on the positioning mold 1 .

[0089] It is understandable that the horizontal calibration mechanism 3 is disposed on the plate 11 and faces the operator, so that the operator can observe the positioning mold 1 through the horizontal calibration mechanism 3 and determine whether the positioning mold 1 is in a horizontal state.

[0090] The number of the horizontal calibration mechanisms 3 may be at least two, and one horizontal calibration mechanism 3 is disposed in the horizontal direction and the vertical direction of the positioning mold 1 .

[0091] The horizontal calibration mechanism 3 can use a bubble level. During adjustment, the horizontal indication of the horizontal calibration mechanism 3 can be used to minimize the offset angle of the positioning mold 1, reduce the error of adjustment through human eye observation, and improve accuracy.

[0092] In one possible implementation, Figure 4 and Fig. 9 As shown, the fixing device applied to the marker further includes a connecting member 4, which is disposed on the positioning mold 1 and is used to connect the positioning mold 1 to a carrier.

[0093] It can be understood that when the positioning mold 1 is connected to the carrier through the connecting member 4, the connecting member 4 is flush with the contact surface, or is located on the side of the contact surface away from the carrier, and the positioning mold 1 and the carrier are detachably connected.

[0094] like Fig.12 As shown, the connecting member 4 can be a magnetic member 41, which is suitable for iron carriers and has the characteristics of good stability, simple installation and disassembly, easy position adjustment, and no residue. It can be suitable for flat surfaces or uneven surfaces.

[0095] like Fig.14 As shown, the connecting member 4 can be a suction cup 42, which is suitable for carriers of different materials, has the characteristics of good stability, simple installation and removal, no residue, etc., and is suitable for relatively flat and smooth surfaces.

[0096] Furthermore, a groove for accommodating the connecting member 4 may be provided on the plate 11 so that the contact surface of the plate 11 can fit with the carrier.

[0097] The connecting piece 4 can be an adhesive sheet with a certain viscosity, which is connected to the carrier through the viscosity of the adhesive sheet. It is suitable for carriers of different materials. Acrylic transparent glue can be used, which has good transparency and flexibility, and strong viscosity. It can be easily torn off without residual glue, and will not damage the surface of the carrier.
