Description

Technical Field

[0001] This utility model relates to the field of protective housing technology, and in particular to a protective housing for a gas analyzer. Background Technology

[0002] An infrared gas analyzer is an instrument that uses infrared light to analyze gases. To reduce wear and tear on the instrument and damage from external factors, it is usually stored and protected with a protective casing when not in use.

[0003] Chinese utility model patent CN222850482U discloses a combined detachable infrared gas analyzer protective shell, including a support device. The top of the support device is equipped with an mounting plate. The top of the mounting plate is respectively provided with an analyzer connection assembly and a protection assembly. The analyzer connection assembly includes an analyzer body set on the top of the mounting plate. The analyzer body has slots on both sides of its exterior. Two symmetrical fixing plates are installed on the top of the mounting plate. A slide rod is connected inside the fixing plate. A locking plate is installed at one end of the slide rod, and a pull plate is installed at the other end of the slide rod. The locking plate and the slot are in an engaging structure. A spring is installed on the outer side of the fixing plate and outside the slide rod. One end of the spring is connected to the locking plate. A pull ring is installed on the outer side of the pull plate.

[0004] When disassembling or installing the protective housing of the aforementioned modular infrared gas analyzer, operators need to pull the pull rings with both hands until both clips are disengaged from the slots or both clips are engaged in the slots. The entire process requires two operators to work together, which increases the waste of human resources. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a protective housing for a gas analyzer.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a protective shell for a gas analyzer, comprising a protective shell body and a detector body placed on the inner bottom wall of the protective shell body. The detector body is provided with two clamping plates symmetrically arranged about the middle of the detector body. The bottom of the horizontal section on the upper side of the clamping plates is close to the top of the detector body. A fixing plate is fixed inside the protective shell body. A sliding rod is fixed on the clamping plate. The number of clamping plates, the number of fixing plates, and the number of sliding rods are all equal and their positions correspond one-to-one. The sliding rod passes through the fixing plate and slides in cooperation. The protective shell body is provided with a displacement component for driving the two clamping plates to move away from or closer to each other.

[0007] By adopting the above technical solution, workers use a displacement component to move the two clamping plates away from each other until they separate from the instrument body. At this point, the instrument body can be removed from its protective casing, completing the disassembly process. Similarly, placing the instrument body between the two clamping plates and using the displacement component to move them closer together until the upper horizontal sections of the clamping plates are flush with the instrument body completes the installation process. The entire process can be completed by a single person, thus reducing the waste of human resources.

[0008] Furthermore, the displacement assembly includes an adjustment plate slidably disposed within the protective shell body, an adjustment column rotatably mounted on the bottom of the clamping plate, and a first screw rod that passes through the adjustment plate and is threadedly connected. The first screw rod passes through the protective shell body and is rotatably connected. The displacement assembly also includes a knob fixedly sleeved on the first screw rod. An adjustment groove that slides through the first screw rod and engages with the adjustment column is provided. The number of adjustment columns, the number of adjustment grooves, and the number of clamping plates are equal and their positions correspond one-to-one.

[0009] By employing the above technical solution, rotating the knob drives the first screw to rotate, causing the adjusting plate threadedly connected to the first screw to move towards the detector body. The adjusting plate moves along the adjusting groove, thereby causing the adjusting plate and the clamping plate connected to the adjusting plate to move away from each other, thus achieving the purpose of loosening the detector body. Similarly, rotating the knob drives the first screw to rotate in the opposite direction, causing the adjusting plate threadedly connected to the first screw to move away from the detector body. The adjusting plate moves along the adjusting groove, thereby causing the adjusting plate and the clamping plate connected to the adjusting plate to move towards each other, thus achieving the purpose of clamping the detector body.

[0010] Furthermore, a placement groove is provided on the bottom inner wall of the protective shell body, and the detector body is inserted into the placement groove.

[0011] By adopting the above technical solution and setting the placement groove, the stability of the detector body when it is fixed is improved.

[0012] Furthermore, the protective shell body is provided with a lifting mechanism. The bottom of the protective shell body is provided with a sliding groove communicating with the placement groove. The lifting mechanism includes a lifting component, which includes a lifting plate slidably disposed in the placement groove, a lifting block fixed to the bottom of the lifting plate, an adjusting block slidably disposed in the sliding groove, a connecting plate disposed on the adjusting block, and a connecting column rotatably mounted on the connecting plate. The lifting block is provided with a lifting groove through which the connecting column passes and is inserted and engaged. The lifting mechanism also includes a moving component for driving the adjusting block to move.

[0013] By adopting the above technical solution, during the disassembly of the detector body, the moving component drives the adjusting block to move, thereby causing the connecting plate connected to the adjusting block, the connecting column connected to the connecting plate, and the lifting and displacement components connected to the connecting plate to move. The connecting column first moves along the upper horizontal section of the lifting groove, then moves from the horizontal section of the lifting groove to the inclined section of the lifting groove, and finally moves from the inclined section of the lifting groove to the lower horizontal section of the lifting groove. Since the distance between the lifting plates in the inclined section of the lifting groove gradually increases from the adjusting block to the first screw, the lifting block, the lifting plate connected to the lifting block, and the detector body placed on the top of the lifting plate all rise until the detector body moves out of the placement groove, making it easy to remove the detector body from the placement groove.

[0014] Furthermore, the moving component includes a second screw rod that passes through the protective shell body and is threadedly connected to the adjusting block, a main synchronous pulley that is fixedly sleeved on the first screw rod, a driven synchronous pulley that is fixedly sleeved on the second screw rod, and a synchronous belt for connecting the main synchronous pulley and the driven synchronous pulley, wherein the synchronous belt meshes with both the main synchronous pulley and the driven synchronous pulley.

[0015] By adopting the above technical solution, the first screw is rotated and drives the main synchronous pulley to rotate, so that the synchronous belt meshing with the main synchronous pulley, the driven synchronous pulley meshing with the synchronous belt, and the second screw connected to the driven synchronous pulley all rotate. This causes the adjusting block threadedly connected to the second screw to move, thereby achieving the purpose of lifting the detector body while disassembling it, which facilitates the use of the device.

[0016] Furthermore, the protective shell body is provided with a shielding component, which includes a protective cover rotatably mounted on the protective shell body and a limiting block that penetrates the protective shell body and slides in cooperation with the protective shell body. The limiting block is provided with a threaded through hole that is threadedly connected to the second screw, and the protective cover is provided with a limiting through hole that is inserted into the limiting block.

[0017] By adopting the above technical solution, rotating the second screw causes the limiting block to slide against the main body of the protective shell due to the threaded connection between the second screw and the threaded through hole. This allows the limiting block to move until it separates from the limiting through hole. At this point, the protective cover can be flipped over until the detector body is exposed to the outside, allowing the device to perform normal testing. The protective cover provides protection (when the limiting block separates from the limiting through hole, the connecting column is still in the horizontal section above the lifting groove, and the clamping plate is still in a stationary state).

[0018] Furthermore, the bottom of the upper horizontal section of the clamping plate is provided with a groove of a wave-shaped structure.

[0019] By adopting the above technical solution, the groove design improves the stability when the clamping plate is connected to the detector body.

[0020] In summary, the present invention has the following beneficial effects: In this application, by setting up a clamping plate and a displacement component, only one person is needed to complete the disassembly or installation of the detector body, thereby reducing the waste of human resources.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-4As shown in the illustration, this application discloses a protective housing for a gas analyzer, including a protective housing body 1, a detector body 2, a displacement assembly 6, and a lifting mechanism 8. The detector body 2 is placed on the inner bottom wall of the protective housing body 1. Two clamping plates 3 are symmetrically arranged about the middle of the detector body 2, with the bottom of the horizontal section of the upper side of the clamping plates 3 abutting against the top of the detector body 2. A fixing plate 4 is fixed inside the protective housing body 1, and a sliding rod 5 is fixed on the clamping plates 3. The number of clamping plates 3, the number of fixing plates 4, and the number of sliding rods 5 are all equal and their positions correspond one-to-one. The sliding rods 5 pass through the fixing plates 4 and slide in cooperation. The operator uses the displacement assembly 6 to drive the two clamping plates 3 away from each other until the two clamping plates 3 separate from the detector body 2. At this point, the detector body 2 can be removed from the protective housing body 1, thus completing the disassembly operation of the detector body 2. Similarly, the detector body 2 is placed between two clamping plates 3, and the two clamping plates 3 are driven to move closer to each other by the displacement component 6 until the upper horizontal section of the two clamping plates 3 is in close contact with the detector body 2. The installation operation of the detector body 2 can be completed. The whole process can be completed by one person alone, thereby reducing the waste of human resources.

[0028] A displacement assembly 6 is mounted on the protective shell body 1. The displacement assembly 6 drives the two clamping plates 3 to move away from or towards each other. The displacement assembly 6 includes an adjusting plate 61, an adjusting column 62, a first screw 63, and a knob 64. The adjusting plate 61 is slidably disposed within the protective shell body 1. The adjusting column 62 is rotatably mounted on the bottom of the clamping plate 3. The first screw 63 passes through the adjusting plate 61 and is threadedly connected. The first screw 63 passes through the protective shell body 1 and is rotatably connected. The knob 64 is fixedly sleeved on the first screw 63. An adjusting groove 65 is provided on the first screw 63, which slides and engages with the adjusting column 62. The number of adjusting columns 62, the number of adjusting grooves 65, and the number of clamping plates 3 are equal and their positions correspond one-to-one. Rotating knob 64 causes the first screw 63 to rotate, moving the adjusting plate 61, which is threadedly connected to the first screw 63, towards the detector body 2. The adjusting plate 61 moves along the adjusting groove 65, causing both the adjusting plate 61 and the clamping plate 3 connected to it to move away from each other, thus releasing the detector body 2. Similarly, rotating knob 64 causes the first screw 63 to rotate in the opposite direction, moving the adjusting plate 61, which is threadedly connected to the first screw 63, away from the detector body 2. The adjusting plate 61 moves along the adjusting groove 65, causing both the adjusting plate 61 and the clamping plate 3 connected to it to move closer together, thus clamping the detector body 2.

[0029] A placement groove 7 is provided on the inner bottom wall of the protective shell body 1. The detector body 2 is inserted into the placement groove 7. A sliding groove 9 communicating with the placement groove 7 is provided on the bottom of the protective shell body 1. The placement groove 7 improves the stability of the detector body 2 when it is fixed.

[0030] A lifting mechanism 8 is mounted on the protective shell body 1. The lifting mechanism 8 includes a lifting component 81 and a moving component 82. The lifting component 81 includes a lifting plate 811, a lifting block 812, an adjusting block 813, a connecting plate 814, and a connecting column 815. The lifting plate 811 is slidably disposed in the placement groove 7. The lifting block 812 is fixed to the bottom of the lifting plate 811, and a lifting groove 10 is provided through the lifting block 812 for the connecting column 815 to pass through and be inserted into. The adjusting block 813 is slidably disposed in the sliding groove 9, the connecting plate 814 is disposed on the adjusting block 813, and the connecting column 815 is rotatably mounted on the connecting plate 814. During the disassembly of the instrument body 2, the moving component 82 drives the adjusting block 813 to move, thereby causing the connecting plate 814 connected to the adjusting block 813, the connecting column 815 connected to the connecting plate 814, and the lifting component 81 and displacement component 6 connected to the connecting plate 814 to move. The connecting column 815 first moves along the upper horizontal section of the lifting groove 10, then moves from the horizontal section of the lifting groove 10 to the inclined section of the lifting groove 10, and finally moves from the inclined section of the lifting groove 10 to the lower horizontal section of the lifting groove 10. Since the distance between the lifting plates 811 in the inclined section of the lifting groove 10 gradually increases from the adjusting block 813 to the first screw 63, the lifting block 812, the lifting plate 811 connected to the lifting block 812, and the instrument body 2 placed on the top of the lifting plate 811 all rise until the instrument body 2 moves out of the placement groove 7, making it easy for the instrument body 2 to be taken out of the placement groove 7.

[0031] The moving component 82 drives the adjusting block 813 to move. The moving component 82 includes a second screw 821, a main synchronous pulley 822, a driven synchronous pulley 823, and a synchronous belt 824. The second screw 821 passes through the protective housing body 1 and is threadedly connected to the adjusting block 813. The main synchronous pulley 822 is fixedly sleeved on the first screw 63. The driven synchronous pulley 823 is fixedly sleeved on the second screw 821. The synchronous belt 824 connects the main synchronous pulley 822 and the driven synchronous pulley 823, and the synchronous belt 824 meshes with both the main synchronous pulley 822 and the driven synchronous pulley 823. Rotating the first screw 63 drives the main synchronous pulley 822 to rotate, causing the synchronous belt 824 meshing with the main synchronous pulley 822, the driven synchronous pulley 823 meshing with the synchronous belt 824, and the second screw 821 connected to the driven synchronous pulley 823 to rotate. This, in turn, causes the adjusting block 813 threadedly connected to the second screw 821 to move, thereby achieving the purpose of lifting the detector body 2 while disassembling it, making the device easier to use.

[0032] A shielding assembly 11 is mounted on the protective housing body 1. The shielding assembly 11 includes a protective cover 111 and a limiting block 112. The protective cover 111 is rotatably mounted on the protective housing body 1, and the limiting block 112 is through-mounted on the protective housing body 1 and slides in cooperation with it. A threaded through hole 113 is provided through the limiting block 112, which is threadedly connected to the second screw 821. A limiting through hole 12 is provided through the protective cover 111, which is inserted into the limiting block 112. When the second screw 821 is rotated, since the second screw 821 is threadedly connected to the threaded through hole 113, the limiting block 112 slides in cooperation with the protective housing body 1, thereby causing the limiting block 112 to move until it separates from the limiting through hole 12. At this point, the protective cover 111 can be flipped over until the detector body 2 is exposed to the outside, and the device can then perform normal detection work. The protective cover 111 provides protection.

[0033] The bottom of the upper horizontal section of the clamping plate 3 is provided with a wavy groove. The groove improves the stability when the clamping plate 3 is connected to the detector body 2.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
