Description

Technical Field

[0001] The utility model belongs to the field of detection equipment, in particular to a wire passing device. Background Art

[0002] A portable testing device is usually used in the field of food, water quality or other testing. Taking water quality testing as an example, the testing device includes an upper box and a lower box connected by hinges. The upper box is placed in an LCD screen, and a variety of testing instruments are placed in the lower box. When in use, the upper box is flipped open, and the test data of the lower box is obtained by observing the LCD screen. In the testing equipment currently used, the upper box is 180° away from the lower box after opening. In order to facilitate the operator to observe the display screen, some testing equipment installs a torsion spring at the hinge position to limit the opening angle between the upper box and the lower box to 90°. However, whether it is 180° or 90°, it does not meet the viewing distance requirements between the display screen and the operator required by 4.1.2.1 of GJB3812-1999. Therefore, these two angles are not comfortable angles for the operator to observe the display screen, and do not meet the requirements of ergonomic design.

[0003] In addition, the detection instrument in the lower box body and the LCD screen of the upper box body need to be connected by cables. In order to protect the cables from being damaged during long-term use, it is necessary to introduce a wire-passing structure to fix and protect the cables. The utility model patent with publication number CN205355704U discloses a wire-passing fixing block and an integrated suitcase using the wire-passing fixing block, including a convex groove structure fixedly connected to the upper cover of the suitcase, and a groove structure fixedly connected to the lower cover of the suitcase, and the convex groove structure and the groove structure are rotatably connected. When in use, the cable passes through the first wire-passing window and the first wire-passing cavity in turn, and then extends out of the wire-passing holes on the left and right ends of the convex groove lower cover, enters the second wire-passing cavity, and finally extends out through the second wire-passing window. Since the convex groove structure can rotate with the upper cover, the problem of the cable being compressed, deformed or broken when the upper cover rotates is avoided.

[0004] The wire-passing fixing block in the above patent performs the functions of cable threading, fixing, protecting and rotating. However, the opening and closing angles between the upper cover and the lower cover are still limited by a torsion spring, i.e., the opening angle of the upper cover is 90°, which also does not meet the sight distance requirements of 4.1.2.1 in GJB3812-1999.

[0021] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0022] (1) The utility model includes a male seat component and a female seat component that are rotatably connected. A rotating block is provided on the female seat component. The edge of the rotating block is raised in an arc shape. Correspondingly, an arc groove that matches the arc edge of the rotating block is provided at the position of the male seat component corresponding to the rotating block. In actual use, the male seat component is fixed on the lower box body, and the female seat component is fixed on the upper box body. When the upper box body is opened, the female seat component rotates with the upper box body, and the rotating block rotates in the arc groove. When the female seat component is rotated to the extension section of the male seat component abutting against the male seat component, it cannot be rotated any further. This is the maximum angle at which the upper box body can be opened. In addition, the extension section on the male seat component limits the female seat component, so that the upper box body remains open at this angle. The angle is 110° to 120°, which meets the viewing distance requirements between the display screen and the operator as required by 4.1.2.1 of GJB3812-1999, is a comfortable angle for the operator to observe the display screen, and meets the requirements of ergonomic design.

[0023] (2) The utility model also includes a first wire-passing block integrally arranged with the male seat component, a second wire-passing block and a third wire-passing block integrally arranged with the female seat component, and the female seat and the female seat cover, as well as the male seat and the male seat cover are all detachably connected. The male seat is first fixed to the lower box body, and after the cable is routed in the first cavity and the wire-passing hole, it extends out from the left port or the right port of the first wire-passing block, and then the male seat cover is buckled, and the female seat component is also buckled in the same way. This structure can ensure smooth threading. Finally, the cable passes through the lower box body into the first cavity, then into the second cavity, and finally into the upper box body through the second wire-passing port, thereby realizing the threading and fixing functions of the cable;

[0024] (3) The utility model also includes a first shielding block, and at least one threading hole is set at the position corresponding to the first wire passing port on the first shielding block. The threading hole can be set to different diameters according to the actual threading needs, which has wider applicability and higher efficiency. After multiple cables pass through the first cavity, according to the position of the upper box body to be wired, the multiple cables are selectively extended from the left port or the right port of the wire passing hole, and finally enter the upper box body through the corresponding second wire passing port. This structure ensures that the cables passing through the upper box body are closest to the wire passing port to be wired, and the wiring operation is faster;

[0025] (4) The first shielding block in the utility model is a split structure, including an upper shielding block and a lower shielding block. The upper shielding block and the lower shielding block are fixed and spliced ​​to form a complete threading hole. Since the ends of the cables are usually scattered, compared with directly aligning the cables with the threading holes, this structure can ensure fast and accurate threading;

[0026] (5) A second shielding block is provided between the first shielding block and the male socket to improve the flatness of the fixing surface of the first shielding block so as to make the fixing more secure.

[0027] To sum up, the utility model can achieve that the angle formed by the upper box body and the lower box body after opening meets the ergonomic design requirements, making the operator more comfortable when observing the display screen on the box body for a long time; the utility model is suitable for industries such as instruments and meters, medical equipment, etc., and is used to realize cable threading, protection and fixing functions.

[0041] The preferred embodiment of the utility model is described below in conjunction with the accompanying drawings. It should be understood that the wire passing device described here is a preferred embodiment, which is only used to illustrate and explain the utility model and does not constitute a limitation of the utility model.

[0042] The directional terms or positional relationships such as "left" and "right" described in the embodiments are based on the drawings in the specification of the utility model. Figure 4 The orientation relationship is only for the convenience of describing the present invention and simplifying the description. It does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the content protected by the present invention.

[0043] like Figures 1 to 9 As shown, this embodiment includes a male seat component 1 and a female seat component 2, both of which are hollow structures inside. The cables to be threaded pass through the male seat component 1 and the female seat component 2 in turn and then come out, thereby realizing the cable threading and fixing functions; the male seat component 1 is rotatably connected to the female seat component 2, and a limiting portion for limiting the rotation angle of the female seat component 2 is provided on the male seat component 1, so that the rotation angle of the female seat component 2 is any value between 110° and 120°, which meets the viewing distance requirements between the display screen and the operator required by 4.1.2.1 of GJB3812-1999, is a comfortable angle for the operator to observe the display screen, and meets the requirements of ergonomic design.

[0044] This embodiment is explained by taking a portable test box used for water quality testing equipment as an example. The test box includes a hinged upper box body 3 and a lower box body 4. A display screen is provided in the upper box body 3, and a testing instrument is provided in the lower box body 4. When threading, the cables inside the lower box body 4 need to be passed through the wire-passing device into the upper box body 3.

[0045] 1. Male socket assembly 1;

[0046] like Figure 2 , Figure 4 , Figure 5As shown, the male socket assembly 1 includes a male socket 101 and a male socket cover 102. The front surface of the male socket 101 is provided with a screw hole and a first wire-passing opening 103. The male socket cover 102 and the male socket 101 are detachably connected, that is, the male socket cover 102 and the male socket 101 can be snapped together by plugging, or the snapped male socket cover 102 and the male socket 101 can be fixed together by screws. A first cavity 104 for threading is formed inside the snapped male socket assembly 1, and the first cavity 104 is connected to the first wire-passing opening 103;

[0047] like Figure 4 As shown, the male seat assembly 1 is provided with a first wire block 107 for the cable to pass through. The first wire block 107 is a cylinder, and its axial direction is arranged along the left and right directions. A circular wire hole 115 is opened on the first wire block 107 along its axial direction, and the wire hole 115 is connected to the first cavity 104 for passing the wire. According to the actual installation position of the cable on the upper box body 3, for example, some cables need to be connected to the left end position of the upper box body 3, and other cables need to be connected to the right end position of the upper box body 3. Then, when threading, the cable can be selected to pass through the position of the left port or the right port of the first wire block 107, so as to be closer to the wiring position on the upper box body 3.

[0048] like Figure 5 As shown, in this embodiment, the longitudinal section of the first wire passing block 107 is a circular ring, and the first wire passing block 107 is spliced ​​by two semi-circular arc pieces 108, one of which is integrally provided with the male seat 101, and the other is integrally provided with the male seat cover 102. After the male seat cover 102 is buckled onto the male seat 101, the two semi-circular arc pieces 108 are buckled to form a complete first wire passing block 107. It should be supplemented that the first wire passing block 107 is not limited to a cylindrical structure, but can also be an elliptical, square or other arbitrary structure, as long as a wire passing hole 115 is provided for the cable to pass through.

[0049] When in use, the male socket 101 is fixed on the lower box body 4, and the cables in the lower box body 4 enter the first cavity 104 through the first wire-passing opening 103, and then extend out through the left port or the right port of the first wire-passing block 107 and pass into the female socket assembly 2.

[0050] In order to improve this embodiment, Figure 2 As shown, the male socket assembly 1 also includes a first shielding block 109 and a second shielding block 113, which are located inside the lower box body 4 after installation. Figure 7 , Figure 8. An opening 114 for passing the wire is provided on the second shielding block 113 at a position corresponding to the first wire passing opening 103. When in use, after the male seat 101 is fixed on the outer surface of the lower box body 4, the second shielding block 113 is detachably fixed to the male seat 101 inside the lower box body 4 by screws, and then the first shielding block 109 is also detachably fixed to the second shielding block 113 by screws. Three threading holes 112 are provided on the first shielding block 109. The threading holes 112 are provided corresponding to the openings 114 on the second shielding block 113. In this embodiment, the diameters of the three threading holes 112 are 4mm, 7mm, and 7mm, respectively. When threading, the cables inside the lower box body 4 are passed through the threading holes 112 of corresponding sizes and enter the first cavity 104. In this embodiment, the size and number of the threading holes 112 on the first shielding block 109 can also be adjusted according to the size and number of the cables to adapt to the threading function of cables of various specifications. The first shielding block 109 and the second shielding block 113 are both made of metal and can shield electromagnetic interference. In this embodiment, both are made of 5052 aluminum alloy.

[0051] It should be noted that if Figure 2 , Figure 3 As shown, the first shielding block 109 is a split structure, including an upper shielding block 110 and a lower shielding block 111. When installing, first fix the lower shielding block 111 with the second shielding block 113, then place the cables on different threading holes 112, then snap the upper shielding block 110 onto the lower shielding block 111, and fix the upper shielding block 110 with the second shielding block 113. At this time, the upper shielding block 110 and the lower shielding block 111 are spliced ​​to form a complete threading hole 112. The first shielding block 109 is set as a split structure because the threading hole 112 is small in size and the cable ends are usually scattered. When threading, if the cable is directly aligned with the threading hole 112, it is difficult to pass through. This design can ensure the speed and accuracy of threading. The second shielding block 113 is used to improve the flatness of the fixing surface of the first shielding block 109, so that it is fixed more firmly. Similarly, when installing the male socket assembly 1 , first fix the male socket 101 to the lower box 4 , and then buckle the male socket cover 102 onto the male socket 101 after the cable passes through the first cavity 104 and the first wire block 107 .

[0052] 2. Female seat assembly 2;

[0053] like Figure 2 , Figure 5 As shown, the female socket assembly 2 includes a female socket 201 and a female socket cover 202. The front surface of the female socket 201 is fixed to the outer surface of the upper box body 3 by screws. A second wire passing opening 203 is opened on the front surface of the female socket 201. The female socket cover 202 is detachably connected to the female socket 201. The detachable manner is the same as that of the male socket assembly 1, which will not be repeated here. A second cavity 204 for threading is formed inside the female socket assembly 2 after being buckled, and the second cavity 204 is connected to the second wire passing opening 203.

[0054] like Figure 2 , Figure 5 , Figure 6 As shown, the female base assembly 2 is provided with a rotating block 205, and the rotating block 205 includes a second wire block 206 and a third wire block 208; the second wire block 206 is a cylindrical structure as a whole, and a first wire groove 207 is provided on the second wire block 206, and the first wire groove 207 is connected with the second cavity 204, and the notch of the first wire groove 207 corresponds to the left port of the first wire block 107. The second wire block 206 has a similar structure to the first wire block 107, and is formed by splicing two semicircular arc pieces, one of which is integrally arranged with the female base 201, and the other semicircular arc piece is integrally arranged with the female base cover 202. When the female base cover 202 is buckled with the female base 201, the two semicircular arc pieces are spliced ​​to form a complete second wire block 206. The third wire block 208 has the same structure as the second wire block 206, and will not be repeated. The second wire-passing groove 209 on the third wire-passing block 208 is also connected to the second cavity 204, and its groove corresponds to the right port of the first wire-passing block 107. In this embodiment, two second wire-passing ports 203 are provided on the female socket 201. When threading, the cable passing through the left port of the first wire-passing block 107 passes through the second wire-passing block 206 and the second cavity 204 in sequence, and enters the upper box body 3 from the second wire-passing port 203 on the left; the cable passing through the right port of the first wire-passing block 107 passes through the third wire-passing block 208 and the second cavity 204 in sequence, and enters the upper box body 3 from the second wire-passing port 203 on the right, thereby realizing the cable threading and fixing functions.

[0055] It should be noted that when installing the mother socket assembly 2, first fix the mother socket 201 to the upper box body 3. After the cable enters the upper box body 3 through the second wire block 206 or the third wire block 208 and the second cavity 204, the mother socket cover 202 is snapped onto the mother socket 201. This design makes the threading operation easier and faster.

[0056] In this embodiment, both the male socket component 1 and the female socket component 2 are made of 6061 aluminum alloy material, and the surface is blackened, so that the whole device has a certain strength and corrosion resistance. It has been verified by a third party that it can meet the environmental adaptability and strength requirements of temperature, humidity, and salt spray resistance in GJB, and can effectively protect the cables.

[0057] The male seat assembly 1 and the female seat assembly 2 are rotatably connected through the rotating block 205 and the arc groove 105. Specifically, Figure 4As shown, the first wire-passing block 107 is embedded between the second wire-passing block 206 and the third wire-passing block 208. The second wire-passing block 206 has the same structure as the third wire-passing block 208. Taking the second wire-passing block 206 as an example, in this embodiment, the second wire-passing block 206 is a cylindrical structure. Specifically, the second wire-passing block 206 protrudes toward the male seat assembly 1, and the protruding edge (i.e., the lower edge) is arc-shaped. The male seat 101 is provided with an arc groove 105 that is adapted to the arc edge of the second wire-passing block 206. The adaptation here means that the radius of the arc groove 105 is larger than the arc radius of the protrusion of the second wire-passing block 206, so that the second wire-passing block 206 can rotate freely in the arc groove 105, as shown in FIG. Figure 8 As shown, in this embodiment, the rotation angle a of the female base assembly 2 is 115°, which is a more comfortable angle for the operator to observe the display screen.

[0058] When the female seat component 2 rotates, the second wire block 206 rotates in the arc groove 105, and the limiting portion is an extension section 106 formed by extending the edge of the arc groove 105 in a direction away from the lower box body 4. In this embodiment, the extension section 106 is located on the male seat cover 102. When the female seat component 2 rotates to the point where the straight section 210 on the female seat component 2 abuts against the extension section 106, the female seat component 2 cannot continue to rotate, and the upper box body 3 maintains an angle of 115°. Of course, the limiting portion can also adopt any structure in the prior art, such as a fixed limiting block on the male seat cover 102, as long as it can limit the female seat component 2 from rotating to 115° and then not continuing to rotate.

[0059] In the original portable inspection box device, the upper box body 3 is opened at an angle of 180° in the hinged state. When using this embodiment, the device is installed on the side with the hinge point, the male seat component 1 is fixed on the lower box body 4, and the female seat component 2 is fixed on the upper box body 3. When threading, the cables in the lower box body 4 pass through the male seat component 1 and the female seat component 2 and enter the upper box body 3 to complete the cable threading and fixing operation; when the upper box body 3 is opened, the female seat component 2 rotates with the upper box body 3, and stops when the straight section 210 on the female seat component 2 abuts against the extension section 106. At this time, the opening angle of the upper box body 3 meets the viewing distance requirements of 4.1.2.1 of GJB3812-1999 between the display screen and the operator, see Fig. 9 Of course, the extension section 106 can also be adjusted to limit the different rotation angles of the upper box body 3 by changing the structure of the male seat cover 102, so that the opening angle of the upper box body 3 is any value between 110° and 120°. Compared with the upper box body 3 opening to 90° or 180°, the operator can sit for a long time to observe the display screen on the upper box body 3 more comfortably, and the operation is more convenient, which meets the viewing distance requirements of 4.1.2.1 of GJB3812-1999 between the display screen and the operator, and meets the requirements of ergonomic design. The structure is suitable for installation on a rotating mechanism to realize the line-passing function.

[0060] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiment, those skilled in the art can still modify the technical solutions recorded in the above embodiment or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
