Technical Field

[0001] This utility model belongs to the technical field of vertical deviation meter, and specifically relates to a placement device for a vertical deviation meter. Background Technology

[0002] A vertical deviation meter is a specialized instrument used to measure the perpendicularity and deviation of an object. When the perpendicularity and deviation of the object are measured, the values ​​are displayed on a digital display.

[0003] A typical digital display is placed flat on the table, requiring people to look above it, making it inconvenient to read the value. Utility Model Content

[0004] The purpose of this invention is to provide a placement device for a vertical deviation meter to solve one or more technical problems existing in the prior art.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0006] This utility model discloses a placement device for a vertical deviation meter, including a support member, a rotating member, and an adjusting member. The upper end surfaces of the support member and the rotating member form a mounting groove for accommodating a digital display, and the lower end surfaces of the support member and the rotating member form a storage cavity for accommodating the digital display's wires. The support member and the rotating member are rotatably connected, causing the rotating member to be tilted. The support member is connected to the adjusting member, and the output end of the adjusting member is connected to the rotating member to limit the tilt angle of the rotating member.

[0007] The present invention has at least the following beneficial effects: The upper surfaces of the support and rotating components are surrounded by a mounting groove, in which the digital display is placed. The lower surface of the digital display is supported by the upper surface of the rotating component, and the side surface of the digital display is supported by the support. The digital display tilts as the rotating component rotates relative to the support, allowing quality inspectors to directly face and read the displayed values. Reading is convenient, eliminating the need to extend one's head over the horizontally placed digital display to read the values ​​and then retract it to record them, reducing the chance of missed inspections. The digital display's power cord can be hidden and stored in a storage cavity, keeping the work surface neat and orderly.

[0008] The adjusting component and the supporting component are fixed relative to each other. The output end of the adjusting component is connected to the rotating component. The rotating component, which rotates relative to the supporting component, can obtain support through the output end of the adjusting component, thereby limiting the tilt angle of the rotating component and the digital display placed on it. The output end of the adjusting component can adjust the tilt angle of the rotating component and the digital display on it according to the height of the quality inspector, so that the screen of the digital display is facing the eyes of the quality inspector. This makes it easier for quality inspectors of different heights to look directly at the digital display and read the values, improving the applicability of the vertical deviation meter placement device.

[0009] Furthermore, the adjustment mechanism can adjust the tilt angle of the digital display to reduce glare and prevent the light from forming glare spots or white reflections on the screen of the digital display.

[0010] As a further improvement to the above technical solution, the adjusting member includes a fixing member and a locking member. The fixing member is connected to the supporting member, one end of the locking member is threaded through the fixing member, and the other end of the locking member abuts against the rotating member. The output end of the adjusting member is the locking member.

[0011] As a further improvement to the above technical solution, the lower inclined end of the rotating component is connected to a rotating shaft, the rotating shaft is rotatably connected to the support component, the fixing component is located at the upper end of the storage cavity, and the locking component abuts against the upper inclined end of the rotating component from bottom to top.

[0012] As a further improvement to the above technical solution, the inclined upper end of the rotating component is provided with a plurality of first cable tray holes for clamping the digital display wires, and the first cable tray holes are connected to the upper edge of the rotating component.

[0013] As a further improvement to the above technical solution, the inner edge of the first cable hub is provided with a deformable component that can be squeezed and deformed to clamp the digital display wires.

[0014] As a further improvement to the above technical solution, the deformable part is C-shaped or U-shaped.

[0015] As a further improvement to the above technical solution, the lower end of the support member is connected to a base plate, and the support member, the rotating member, and the base plate form a storage cavity with the opening facing backward.

[0016] As a further improvement to the above technical solution, a partition is rotatably connected to one end of the base plate facing the opening of the storage cavity. The partition is detachably connected to the support member. The end of the partition away from the base plate is provided with a plurality of second cable collection holes for clamping digital display wires. The second cable collection holes are connected to the edge of the partition, and the deformation member is provided on the inner edge of the second cable collection holes.

[0017] As a further improvement to the above technical solution, the support member is connected to a stop for protecting the digital display. The stop is mounted above the rotating member, and the stop, the support member, and the rotating member form the mounting groove with an inclined opening.

[0018] As a further improvement to the above technical solution, the rotating component is provided with a plurality of first heat dissipation holes, and the supporting component is provided with a plurality of second heat dissipation holes symmetrically arranged and forming convection at opposite ends.

[0037] Reference Figures 1 to 4 The following are several embodiments of the vertical deviation meter placement device of this utility model.

[0038] like Figures 1 to 4 As shown, the vertical deviation meter placement device 100 of this utility model embodiment includes a support member 200, a rotating member 300 and an adjusting member 400 that are connected to each other.

[0039] It is understood that the support member 200 includes two support plates 210 and one connecting plate 220. The two support plates 210 are symmetrically arranged from left to right, and the left and right ends of the connecting plate 220 are respectively connected to the front ends of the two support plates 210, such as... Figure 1 As shown. When viewed from above and below, the support member 200 is U-shaped.

[0040] It is understood that the support plate 210 is vertically arranged, and its left and right cross-sections can be square, trapezoidal, or triangular, etc. In this embodiment, the support plate 210 is a right-angled trapezoid with a smaller top and a larger bottom, and the hypotenuse of the trapezoidal support plate 210 faces upward and forward. Figures 1 to 4 As shown.

[0041] It is understandable that the connecting plate 220 can be extended vertically, such as... Figure 4 As shown.

[0042] In other embodiments, the connecting plate 220 may be arranged perpendicularly to the hypotenuse of the trapezoidal support plate 210, that is, the connecting plate 220 is arranged at an angle.

[0043] It is understood that the rotating component 300 is a square plate. The rotating component 300 is located within the support component 200, such that the upper end face of the rotating component 300 and the support component 200 form a mounting groove 110 around each other, as shown below. Figure 3 and Figure 4 As shown, a mounting groove 110 is formed on the upper end face of the rotating component 300, the inner end faces of the two support plates 210, and the rear end face of the connecting plate 220. The mounting groove 110 is used to house the digital display 700. The lower end face of the digital display 700 is in contact with the upper end face of the rotating component 300, and the screen of the digital display 700 is parallel to the upper end face of the rotating component 300. A receiving cavity 120 is formed around the lower end face of the rotating component 300 and the support component 200, as shown. Figure 3 and Figure 4 As shown, the lower end face of the rotating component 300, the inner end faces of the two support plates 210 and the rear end face of the connecting plate 220 form a receiving cavity 120, which is used to house the digital display 700 wire 710.

[0044] With this setup, the digital display 700 of the vertical deviation meter is placed on the mounting slot 110, and the excess wires 710 are placed in the storage cavity 120, making the tabletop neat and orderly and avoiding the situation where the wires 710 of the digital display 700 are messily laid on the tabletop, affecting the usable space of the tabletop.

[0045] In existing technology, a typical digital display 700 is placed flat on the table. In actual use, quality inspectors need to move their heads above the digital display 700 and look down to read the values ​​on the screen before recording them, which is quite inconvenient. Furthermore, due to the diffuse reflection of the lighting, the upward-facing digital display 700 can easily affect the quality inspector's ability to read the values, further exacerbating the inconvenience of using the digital display 700.

[0046] To address this, the support 200 and the rotating component 300 are rotatably connected, allowing the rotating component 300 to rotate relative to the support 200 and be in an inclined state. When the rotating component 300 is in an inclined state, the screen of the digital display 700 also tilts and is supported within the angle formed by the rotating component 300 and the connecting plate 220, allowing quality inspectors to directly view the screen of the digital display 700 and read the displayed values ​​directly and accurately without repeatedly moving their heads, thus reducing the likelihood of missed inspections.

[0047] Understandably, the support member 200 and the adjusting member 400 are connected, with the adjusting member 400 receiving support from the support member 200. The output end of the adjusting member 400 is connected to the rotating member 300 to adjust and fix the tilt angle of the rotating member 300, preventing the rotating member 300 from constantly rotating relative to the support member 200 during actual use. Since different quality inspectors have varying heights, the angle required for each inspector to directly view the digital display 700 screen is different. Before use, the inspector can adjust the output end of the adjusting member 400 according to their own height, thereby adjusting the tilt angle of the rotating member 300 so that they can directly read the values ​​displayed on the screen, improving the applicability of the vertical deviation meter placement device 100.

[0048] Understandably, the adjustable tilt angle rotating component 300 can also reduce the glare of the digital display 700. When the digital display 700 shows light spots or white reflections, the quality inspector can change the tilt angle of the digital display 700 through the adjusting component 400 to avoid the screen reflecting the lighting light, which would require the quality inspector to move to read the values.

[0049] In this embodiment, the adjusting member 400 includes a fixing member 410 and a locking member 420, such as Figure 4 As shown. Specifically, the fixing member 410 extends in the left-right direction and is connected to the support member 200, with the two fixed relative to each other. The fixing member 410 is provided with a screw hole, and the outer end face of the locking member 420 is provided with an external thread corresponding to the internal thread of the screw hole. One end of the locking member 420 is threaded through the screw hole, and the other end of the locking member 420 abuts against the rotating member 300. At this time, the output end of the adjusting member 400 is the end of the locking member 420 that abuts against the rotating member 300.

[0050] Thus, quality inspectors can adjust the length of the locking member 420 between the fixed member 410 and the rotating member 300 by turning the locking member 420, thereby adjusting the tilt angle of the rotating member 300. When the length of the locking member 420 between the fixed member 410 and the rotating member 300 is increased by turning it, the angle between the rotating member 300 and the horizontal line becomes larger, making the placement device 100 for the vertical deviation meter equipped with the digital display 700 more suitable for shorter quality inspectors. When the length of the locking member 420 between the fixed member 410 and the rotating member 300 is decreased by turning it, the angle between the rotating member 300 and the horizontal line becomes smaller, making the placement device 100 for the vertical deviation meter equipped with the digital display 700 more suitable for taller quality inspectors.

[0051] It is understood that the fixing member 410 may have multiple screw holes spaced along the second direction to stably support the rotating member 300. In this embodiment, the fixing member 410 has a screw hole in the middle, and the locking member 420 abuts against the upper middle part of the rotating member 300. The locking member 420 is a bolt.

[0052] In this embodiment, the inclined lower end of the rotating member 300 is connected to a rotating shaft 340, such as... Figure 4 As shown, the rotating shaft 340 extends in the left-right direction and passes through the support plate 210. The rotating shaft 340 can be rotatably connected to the support member 200 through a bearing or a circular hole in the support plate 210, thereby realizing the rotatable connection between the rotating member 300 and the support member 200. The fixing member 410 is located at the upper end of the receiving cavity 120, and the fixing member 410 is located below the inclined upper end of the rotating member 300. The locking member 420 is threaded from bottom to top through the fixing member 410, so that the screw head of the locking member 420 is located below the fixing member 410, and the screw rod of the locking member 420 is located above the fixing member 410 and abuts against the lower end face of the inclined upper end of the rotating member 300.

[0053] In some embodiments, the adjusting member 400 may be an adjusting handle, an adjusting gear, and a stop pawl. The adjusting handle and the adjusting gear are coaxially connected, and the adjusting handle and the stop pawl are rotatably connected to the support member 200. The rotating shaft 340 is connected to the rotating gear, and the adjusting gear meshes with the rotating gear. The tilt angle of the rotating member 300 can be adjusted by rotating the adjusting handle. The stop pawl meshes with the adjusting gear or the rotating gear, and functions similarly to the pawl in a conventional ratchet mechanism, used to stop the rotating shaft 340 and fix the tilt angle of the rotating member 300.

[0054] In other embodiments, the adjusting member 400 can be a micro motor connected to the support member 200, with the output end of the micro motor being driven by the rotating shaft 340. Therefore, when the micro motor is powered on, it can drive the rotating shaft 340 to rotate forward or backward, achieving angle adjustment of the rotating member 300 electrically, which is labor-saving and quick. When the micro motor is powered off, the motor shaft automatically locks the rotating shaft 340, thereby fixing the tilt angle of the rotating member 300. The micro motor is an existing forward and reverse reversible motor. This invention does not improve the structure of the micro motor; therefore, those skilled in the art should understand the specific structure and working principle of the micro motor, which will not be specifically explained here.

[0055] It is understandable that the inclined upper end of the rotating component 300 is provided with a plurality of first cable-gathering holes 310, and the plurality of first cable-gathering holes 310 are spaced apart in the left-right direction, such as... Figure 1 As shown, the first cable management hole 310 extends upward and connects to the upper edge of the rotating member 300. The first cable management hole 310 is used to hold the wires 710 of the digital display 700. Thus, when the digital display 700 is placed at an angle in the mounting slot 110, the multiple wires 710 connected to the rear end of the digital display 700 can be respectively inserted into the first cable management hole 310 from the upper edge of the rotating member 300. The remaining wires 710 can be placed in the storage cavity 120, so that the multiple wires 710 can be placed in the storage cavity 120 in an orderly and neat manner, avoiding the multiple wires 710 from getting tangled together.

[0056] It is understandable that the inner edge of the first cable tray 310 is provided with a deformation element 320, such as... Figure 1 As shown, the deformable part 320 can be squeezed and deformed. The deformable part 320 can not only deform and clamp the digital display 700 wire 710 placed in the first hub hole 310, so that the wire 710 is stable in the first hub hole 310 without external force, but also buffer the edge of the first hub hole 310 to prevent the edge of the first hub hole 310 from cutting the wire 710.

[0057] In some embodiments, the first hub hole 310 can be a circular hole, and correspondingly, the deformable member 320 is a C-shaped structure with the opening tilted upward.

[0058] In other embodiments, the first hub hole 310 can be an elongated hole, and correspondingly, the deformable member 320 is a U-shaped structure with the opening tilted upward.

[0059] Understandably, the vertical deviation meter placement device 100 is placed on the table. Therefore, the storage cavity 120 is formed by the table, the support 200 and the rotating part 300, and the opening faces backward. That is, the wire 710 is placed on the table. When the position of the vertical deviation meter placement device 100 is moved, one end of the wire 710 connected to the digital display 700 is moved. However, the remaining wire 710 is directly exposed from the storage cavity 120 to the table. The quality inspector needs to put the wire 710 back into the storage cavity 120, which is inconvenient to use.

[0060] For this purpose, the lower end of the support member 200 is connected to the base plate 500, such as... Figure 3 and Figure 4 As shown, the base plate 500 is horizontally positioned and connected to two support plates 210 and a connecting plate 220 respectively, so that the support member 200, the rotating member 300, and the base plate 500 surround to form a storage cavity 120, as shown. Figure 3 and Figure 4 As shown, the opening of the storage cavity 120 faces rearward. In this way, the wire 710 is located on the base plate 500. When the vertical deviation instrument placement device 100 is moved, the wire 710 also moves with the base plate 500, without the need for quality inspectors to rearrange the wire 710.

[0061] Furthermore, a partition 600 is rotatably connected to the end of the base plate 500 facing the opening of the storage cavity 120 via a pivot. The partition 600 is detachably connected to the support member 200, such as... Figures 2 to 4As shown. In use, the partition 600 rotates upward and connects to the support 200. At this time, the partition 600 forms a barrier around the opening of the storage cavity 120, preventing the accumulated wires 710 from falling directly out of the opening of the storage cavity 120. When the wire 710 malfunctions, such as when the connector of the wire 710 is damaged, the partition 600 and the support 200 can be disassembled and separated. The partition 600 can rotate downward along the pivot, thereby fully exposing the opening of the storage cavity 120, making it easy for quality inspectors to remove the wire 710.

[0062] It is understandable that the partition 600 is provided with a plurality of second cable tray holes 610 spaced apart in the left-right direction, such as Figure 2 and Figure 3 As shown, the second cable management hole 610 is located at the end of the partition 600 away from the bottom plate 500. The second cable management hole 610 connects to the edge of the end of the partition 600 away from the bottom plate 500. The second cable management hole 610 is used to hold one end of the digital display 700 cable 710 that connects to the external structure. The external structure can be a power plug, a measuring mechanism, etc. In this way, the length of the cable 710 extending out of the storage cavity 120 can be controlled through the second cable management hole 610. The extension length of the cable 710 is controlled according to the position of the cable 710 connecting to the external structure and the distance between the storage cavity 120 and the external structure. This makes the end of the cable 710 connected to the external structure neatly and orderly arranged on the table surface, and the end of the cable 710 connected to the digital display 700 orderly arranged on the inclined upper end of the rotating part 300. The middle part of the cable 710 is stably hidden inside the storage cavity 120.

[0063] Understandably, the inner edge of the second hub hole 610 is also provided with a deformation element 320, such as... Figure 3 As shown, the function of the deformable element 320 in the first hub hole 310 is the same as that in the second hub hole 610, and will not be described in detail here.

[0064] Understandably, the support member 200 is connected to a stop, which is used to support and protect the digital display 700, preventing it from falling from the inclined mounting groove 110 and being damaged. The stop is mounted above the rotating member 300, the lower end face of the digital display 700 is against the rotating member 300, the front end face of the digital display 700 is against the connecting plate 220, the left and right end faces of the digital display 700 are respectively limited by two support plates 210, and the inclined upper end face of the digital display 700 is limited by the stop. The stop, the support member 200, and the rotating member 300 form an inclined mounting groove 110 with an opening.

[0065] It is understood that the stop can be a baffle, a strap, or a positioning pin, etc. In this embodiment, the stop is a baffle.

[0066] It is understood that the stop and the support 200 can be fixedly connected by means of screws, welding, or bonding. The stop and the support 200 can also be detachably connected by means of bolts, snap-fit, or magnetic attraction. No specific limitations are made here.

[0067] It is understandable that the rotating part 300 is provided with multiple first heat dissipation holes 330. When the digital display 700 is placed in the mounting slot 110, the lower end face of the digital display 700 is opposite to the multiple first heat dissipation holes 330. The heat generated by the digital display 700 when it is powered on is radiated into the storage cavity 120 through the first heat dissipation holes 330. The rear opening of the storage cavity 120 can exchange the air inside and outside the storage cavity 120, so as to avoid the digital display 700 from overheating and affecting the service life of the digital display 700.

[0068] It is understandable that the support member 200 is provided with a plurality of symmetrical second heat dissipation holes 211, that is, the plurality of second heat dissipation holes 211 are respectively symmetrically arranged on the two support plates 210, so that air can be convectively dissipated in the housing cavity 120, thereby further improving the heat dissipation efficiency of the digital display 700.

[0069] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
