The processed data is then transmitted to the PC, where it is displayed on the computer to provide intuitive data for the operator.

[0003] Currently, a front-end processor for a detection device includes a cabinet, a connecting frame fixed inside the cabinet, and multiple information processing hosts placed inside the connecting frame, with adjacent information processing hosts touching each other.

[0004] Information processing hosts generate heat when they are working. If two adjacent information processing hosts touch each other, it will affect the heat dissipation of the host, causing the host to be in a high-temperature environment, which will affect the overall lifespan of the host. Utility Model Content

[0005] In order to extend the overall service life, this application provides a front-end processor for a detection device.

Due to the presence of the partition block, there will be a gap between the two adjacent information processing hosts. When the information processing host generates heat during operation, it can dissipate through the gap between the two adjacent information processing hosts. Therefore, the partition mechanism can extend the overall service life.

[0010] By adopting the above technical solution, when the size and specifications of the information processing host change, or when the information processing host located in the installation cavity and in contact with the partition block needs to be removed, the toggle block can be moved. The slider connected to the toggle block will then drive the partition block to move, so that the partition block no longer in contact with the information processing host. Therefore, the adjustment mechanism can improve applicability and facilitate the transfer of the information processing host.

[0018] By adopting the above technical solution, when the assembly block on the adjusting block enters the assembly groove, the assembly block will abut against the chamfer on the positioning block, and the assembly block will squeeze the positioning block into the groove, causing the spring to deform; when the positioning block is aligned with the positioning groove, the force of the spring restoring its elastic deformation will drive the positioning block to move, so that the positioning block is engaged with the positioning groove. At this time, the axis of the third through hole coincides with the axis of the second threaded hole, which facilitates the fixing of the assembly bolt.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a front-end processor for a detection device.

The mounting bolt 14 passes through the fifth through hole on the mounting frame 12 and is threadedly connected to the fourth threaded hole on the cabinet 11, thereby fixing the mounting frame 12 to the cabinet 11.

[0037] refer to Figure 2 An installation cavity 121 is formed within the installation frame 12, and an inlet and outlet communicating with the installation cavity 121 are formed on the installation frame 12. A first heat dissipation hole 125 communicating with the installation cavity 121 is formed at the upper end of the installation frame 12. An information processing host 13 is placed inside the installation cavity 121.

[0038] refer to Figure 2 and Figure 3The upper end of the mounting frame 12 is provided with a sliding groove 122 and a sixth through hole 127 communicating with the sliding groove 122. The mounting frame 12 also has multiple first through holes 123 communicating with the sliding groove 122. An adjustment mechanism 3 is provided on the mounting frame 12. The adjustment mechanism 3 includes a slider 31 slidably connected within the sliding groove 122. A lever 32 is fixedly connected to the slider 31, with one end of the lever 32 away from the slider 31 passing through the sixth through hole 127. A first threaded hole is provided on the slider 31. A fixing assembly is provided on the mounting frame 12. The fixing assembly includes a fixing bolt 33, which passes through the first through hole 123 on the mounting frame 12 and is threadedly connected to the first threaded hole on the slider 31.

[0039] A partition block 2 is integrally provided on the slider 31, with the end of the partition block 2 away from the slider 31 located inside the mounting cavity 121. Two partition blocks 2 are provided between two information processing main bodies that are close to each other, and there is a certain gap between the two partition blocks 2. In this embodiment, taking the configuration of three information processing main bodies 13 as an example, the number of partition blocks 2 is four, and the four partition blocks 2 form three individual cavities within the mounting cavity 121; from left to right, the partition blocks 2 are the first partition block 2, the second partition block 2, the third partition block 2, and the fourth partition block 2. The first partition block 2 and the side wall of the mounting frame 12 form the first individual cavity, the second partition block 2 and the third partition block 2 form the second individual cavity, and the fourth partition block 2 and the side wall of the mounting frame 12 form the third individual cavity. One information processing main body 13 is placed in each individual cavity, and the information processing main body 13 can abut against the partition block 2. In this way, under the spacing effect of the partition blocks 2, two adjacent information processing main bodies 13 will not abut against each other, and a gap for heat dissipation is formed between the two information processing main bodies 13. The lower end of the mounting frame 12 has a second heat dissipation hole 126 that communicates with the single-unit cavity, so that the heat generated by the information processing host 13 during operation can also be directly discharged through the first heat dissipation hole 125 and the second heat dissipation hole 126.

[0040] Reference 2 and Figure 4 The lower end of the mounting frame 12 is provided with a second through hole 124 communicating with the single-unit cavity. The mounting frame 12 is provided with a pushing mechanism 4, which includes a pushing block 41 located in the single-unit cavity. The lower end of the pushing block 41 is provided with two adjusting blocks 42. The end of the adjusting block 42 away from the pushing block 41 passes through the second through hole 124. The ends of the two adjusting blocks 42 away from the pushing block 41 are connected to a moving block 43. The moving block 43 abuts against the side wall of the mounting frame 12. In other embodiments, a dovetail block can be fixedly connected to the moving block 43, and a dovetail groove that slides with the dovetail block is provided on the mounting frame 12.

[0041] refer to Figure 4 and Figure 5Both the pushing block 41 and the moving block 43 are provided with assembly slots, both the pushing block 41 and the moving block 43 are provided with third through holes communicating with the assembly slots, and both the pushing block 41 and the moving block 43 are provided with grooves communicating with the assembly slots.

[0042] An assembly mechanism 5 is provided on the adjusting block 42, which is connected to the pushing block 41 and the moving block 43. The assembly mechanism 5 includes an assembly block 51. An assembly block 51 is integrally provided at both ends of the adjusting block 42. The assembly block 51 at one end of the adjusting block 42 engages with the assembly groove on the pushing block 41, and the assembly block 51 at the other end of the adjusting block 42 engages with the assembly groove on the moving block 43. A second threaded hole is provided on the assembly block 51. An assembly bolt 52 is provided on both the pushing block 41 and the moving block 43. The assembly bolt 52 passes through a third through hole and is threadedly connected to the second threaded hole on the assembly block 51.

[0043] Both the pushing block 41 and the moving block 43 are provided with positioning mechanisms 6. The positioning mechanism 6 includes a positioning block 61 that is slidably connected in the groove. The side of the positioning block 61 away from the bottom wall of the assembly groove has a chamfer. The assembly block 51 has a positioning groove that engages with the positioning block 61.

[0044] Both the pushing block 41 and the moving block 43 are provided with an adjustment mechanism 7. The adjustment mechanism 7 includes an adjustment block 71 integrally formed with the positioning block 61. A spring 62 is provided in the groove. One end of the spring 62 is connected to the bottom wall of the groove and the other end is connected to the adjustment block 71. Both the pushing block 41 and the moving block 43 are provided with an adjustment assembly 72. The adjustment assembly 72 includes an adjustment shaft 721. The adjustment shaft 721 is rotatably set on both the pushing block 41 and the moving block 43. One end of the adjustment shaft 721 is located in the groove. An adjustment gear 722 is keyed to the adjustment shaft 721 located in the groove. An adjustment rack 723 that meshes with the adjustment gear 722 is integrally formed on the adjustment block 71. The end of the adjustment shaft 721 away from the adjustment gear 722 is coplanar with the side wall of the pushing block 41 or the moving block 43, and the end of the adjustment shaft 721 away from the adjustment gear 722 has an internal hexagonal groove.

[0045] First, move the adjusting block 42 or the pushing block 41 so that the assembly block 51 at one end of the adjusting block 42 enters the assembly groove of the pushing block 41. The assembly block 51, which moves relative to the pushing block 41, will first abut against the chamfer on the positioning block 61. The assembly block 51 will press against the chamfer on the positioning block 61, so that the positioning block 61 enters the groove. The adjusting block 71 on the positioning block 61 presses against the spring 62. When the assembly block 51 abuts against the bottom wall of the assembly groove on the pushing block 41, the positioning block 61 aligns with the positioning groove on the assembly block 51. The force of the spring 62 restoring its elastic deformation drives the adjusting block 71 to move. The adjusting block 71 drives the positioning block 61 to move, so that the positioning block 61 is engaged with the positioning groove on the assembly block 51. At this time, the axis of the third through hole on the pushing block 41 and the axis of the second threaded hole on the assembly block 51 coincide. Then, the assembly bolt 52 passes through the third through hole on the pushing block 41 and is threadedly connected to the second threaded hole on the assembly block 51, so as to realize the fixed connection between the adjusting block 42 and the pushing block 41. Then, push block 41 and adjusting block 42 are placed into the single cavity of mounting frame 12. Then, the end of adjusting block 42 away from push block 41 passes through the second through hole 124 on mounting frame 12. Next, move moving block 43 so that the assembly block 51 of the end of adjusting block 42 away from push block 41 enters the assembly groove of moving block 43. When the assembly block 51 on adjusting block 42 abuts against the bottom wall of the assembly groove on moving block 43, the assembly bolt 52 passes through the third through hole on moving block 43 and is threadedly connected to the second threaded hole on assembly block 51 to achieve fixed connection between adjusting block 42 and moving block 43.

[0046] When it is necessary to separate the push block 41 or the moving block 43 from the adjusting block 42, first rotate the assembly bolt 52 to separate the assembly bolt 52 from the second threaded hole; then use the internal hexagonal plate to engage with the internal hexagonal slot on the adjusting shaft 721, rotate the internal hexagonal wrench, the internal hexagonal wrench drives the adjusting shaft 721 to rotate, the adjusting gear 722 on the adjusting shaft 721 drives the adjusting rack 723 to move, the adjusting rack 723 drives the adjusting block 71 to move, the adjusting block 71 drives the positioning block 61 to move, so that the positioning block 61 engages with the positioning groove on the assembly block 51, and finally separate the assembly block 51 from the assembly groove.

[0047] refer to Figure 1 and Figure 2 The information processing host 13 is provided with a connection component 8, which includes a connection plate 81 fixedly connected to the information processing host 13. The connection plate 81 has a fourth through hole, and the side wall of the mounting frame 12 has a third threaded hole. The connection plate 81 is provided with a connection bolt 82, which passes through the fourth through hole on the connection plate 81 and is threadedly connected to the third threaded hole on the mounting frame 12.

[0048] In this embodiment, the information processing host 13 can be understood as an industrial control computer, and an air conditioner or exhaust fan is installed in the cabinet 11 to dissipate the heat in the accommodating cavity 111.

[0049] The implementation principle of a front-end processor for a detection device according to an embodiment of this application is as follows: When the information processing host 13 is located in the single cavity within the mounting frame 12, the connecting plate 81 abuts against the mounting frame 12, and the connecting bolt 82 passes through the fourth through hole on the connecting plate 81 and is threadedly connected to the third threaded hole on the mounting frame 12. The information processing host 13 abuts against the corresponding partition block 2, and the end of the information processing host 13 away from the connecting plate 81 abuts against the pushing block 41. At this time, the adjusting block 42 abuts against the side wall of the second through hole 124 away from the inlet and outlet of the mounting frame 12. Thus, when the information processing host 13 is working, the exhaust can be discharged through the gap between two adjacent information processing hosts 13, or through the inlet and outlet, the first heat dissipation hole 125, and the second heat dissipation hole 126 on the mounting frame 12.

[0050] When the information processing host 13 needs to be replaced or repaired, the operator first rotates the connecting bolt 82 to separate the connecting bolt 82 from the third threaded hole on the mounting frame 12; then pulls the moving block 43, the adjusting block 42 on the moving block 43 drives the pushing block 41 to move, and the pushing block 41 will push the information processing host 13 to move, so that the end of the information processing host 13 near the connecting plate 81 passes through the inlet and outlet of the mounting frame 12, and then the operator moves the information processing host 13.

[0051] Before the pusher block 41 pushes the information processing host 13 to move, the operator can first rotate the fixing bolt 33 to separate the fixing bolt 33 from the first threaded hole on the slider 31, then move the slider 31, which drives the separator block 2 to move so that the separator block 2 no longer resists the information processing host 13; then the pusher block 41 is used to push the information processing host 13 to move.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
