Description

Technical Field

[0001] This utility model relates to the field of pressure transmitter technology, and more specifically, to a transmitter housing structure with dual power supply switching capability. Background Technology

[0002] A pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. It can convert the physical pressure parameters of gas, liquid, etc. sensed by the pressure sensing element sensor into standard electrical signals to supply secondary instruments such as indicators, alarms, recorders, and regulators for measurement, indication, and process regulation.

[0003] A search revealed a housing structure for a pressure transmitter in the prior art, with patent publication number CN223597068U. The specification states that the device uses a heat dissipation extension tube fixedly connected at the intersection of the diagonal lines below the sensor host. The sufficiently long heat dissipation extension tube can significantly reduce the temperature of the detection medium flowing in the pipeline, protecting the internal circuitry and components.

[0004] However, in actual use, the electronic components inside the casing of the cited document still generate heat after prolonged use. The heat dissipation extension tube alone cannot dissipate the heat generated by the electronic components in a timely manner, resulting in low heat dissipation efficiency and thus affecting the service life of the electronic components. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a transmitter housing structure with dual power supply switching, so as to solve the problem that in the prior art, the heat generated by electronic components cannot be dissipated in time by heat dissipation extension tubes alone, resulting in low heat dissipation efficiency and thus affecting the service life of electronic components.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a transmitter housing structure with dual power supply switching, including a housing, with placement slots on both the left and right sides of the housing, and slots on both the front and rear sides of the placement slots, with a locking block inside the slot, and a heat sink slidably connected to the outside of the locking block, with a support block one fixedly connected to the adjacent side of each of the two heat sinks, and a support block two slidably connected to the outside of the support block one, and the support block two fixedly connected to the inner wall of the placement slot.

[0007] The heat sink has multiple mounting slots inside. The end of the card block away from the slot is fixedly connected to a mounting plate. The end of the mounting plate away from the card block is fixedly connected to a pull rope. An elastic element is sleeved on the outside of the pull rope. The end of the pull rope away from the mounting plate is fixedly connected to a pull block.

[0008] The heat sink has two slots on its outer surface, and two limiting blocks are fixedly connected to the inner wall of the slots. Multiple connecting blocks are fixedly connected to the inner wall of the placement slot. Insert blocks are fixedly connected inside the connecting blocks, and two limiting grooves are formed on the outer surface of the insert blocks.

[0009] The card block is slidably connected inside the mounting groove, the mounting plate is slidably connected inside the mounting groove, and one side of the pull rope is slidably connected inside the mounting groove.

[0010] The heat sink has two grooves on its outside, the pull block is slidably connected inside the grooves, and the other side of the pull rope is slidably connected inside the grooves.

[0011] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting plate.

[0012] The heat sink is slidably connected inside the connecting block, and the insert block slides relative to the outside of the heat sink.

[0013] The insert is slidably connected inside the slot, the insert slides against the outside of the limiting block, and the limiting block fits against the inside of the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, by opening placement slots on both sides of the housing and inserting heat sinks inside the placement slots, it is possible to conveniently dissipate heat from the electronic components inside the housing and to conveniently replace the heat sinks. This not only results in high heat dissipation efficiency but also does not affect the efficiency of the transmitter, making it economical to use. Attached Figure Description

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1: Please refer to Figures 1 to 7 This utility model provides a technical solution: a transmitter housing structure with dual power supply switching, including a housing 1. Placement slots 2 are provided on both the left and right sides of the housing 1. Slots 3 are provided on both the front and rear sides inside the placement slots 2. Slots 4 are engaged inside the slots 3. Heat sinks 5 are slidably connected to the outside of the slots 4, thus limiting the position of the heat sinks 5. The heat sinks 5 are used to dissipate heat from the housing 1, and multiple filters are installed inside the heat sinks 5 to prevent dust from entering the interior of the housing 1. Support blocks 1 6 are fixedly connected to the adjacent sides of the two heat sinks 5. Support blocks 2 7 are slidably connected to the outside of support blocks 1 6. Support blocks 2 7 are fixedly connected to the inner wall of the placement slots 2, making the installation of the heat sinks 5 relatively stable.

[0027] When the heat sink 5 needs to be installed, after the heat sink 5 is slid into the inside of the placement slot 2, the support block 1 6 can be slid into the inside of the support block 2 7. Then, the locking block 4 is moved outward so that the locking block 4 can engage with the inside of the locking slot 3, thereby making it easy to install the heat sink 5. Conversely, the heat sink 5 can be disassembled, thereby making it easy to dissipate heat from the electronic components inside the housing 1 and to easily replace the heat sink 5. This not only results in high heat dissipation efficiency but also does not affect the efficiency of the transmitter, making it economical to use.

[0028] Example 2: Based on Example 1, to facilitate the pulling of the locking block 4, the heat sink 5 has multiple mounting slots 8 inside. The locking block 4 is slidably connected inside the mounting slots 8, which provide space for the locking block 4 to move. A mounting piece 9 is fixedly connected to the end of the locking block 4 away from the slot 3. The mounting piece 9 is slidably connected inside the mounting slot 8, which limits the mounting piece 9, preventing it from shifting during sliding. A pull rope 10 is fixedly connected to the end of the mounting piece 9 away from the locking block 4. An elastic element 11 is sleeved on the outside of the pull rope 10, and one end of the elastic element 11 is fixedly connected to... The other end of the elastic element 11 is fixedly connected to the mounting plate 9 on the inner wall of the mounting groove 8. The end of the pull rope 10 away from the mounting plate 9 is fixedly connected to the pull block 12. Two sliding grooves 13 are opened on the outside of the heat sink 5. The pull block 12 is slidably connected to the inside of the sliding groove 13. The sliding groove 13 limits the pull block 12, so that the pull block 12 can slide smoothly. One side of the pull rope 10 is slidably connected to the inside of the mounting groove 8, and the other side of the pull rope 10 is slidably connected to the inside of the sliding groove 13. The mounting groove 8 and the sliding groove 13 limit the pull rope 10, so that the pull rope 10 will not deviate when sliding.

[0029] When the locking block 4 needs to be pulled, by moving the two locking blocks 12 to a closer side, the locking blocks 12 can pull the pulling rope 10 to move inward, so that the pulling rope 10 can drive the mounting piece 9 to squeeze the elastic element 11 to deform, thereby allowing the mounting piece 9 to pull the locking block 4 into the interior of the mounting groove 8. Conversely, by releasing the locking blocks 12, the elastic element 11 can perform a reset movement, thereby allowing the elastic element 11 to push the mounting piece 9 to move outward, so that the mounting piece 9 can push the locking block 4 to engage with the interior of the locking groove 3.

[0030] Example 3: Based on Example 2, in order to further limit the heat sink 5, two slots 14 are opened on the outside of the heat sink 5. Two limiting blocks 15 are fixedly connected to the inner wall of the slots 14. Multiple connecting blocks 16 are fixedly connected to the inner wall of the placement slot 2. The heat sink 5 is slidably connected to the inside of the connecting blocks 16, so that the heat sink 5 can be limited. An insert 17 is fixedly connected to the inside of the connecting blocks 16. The insert 17 slides against the outside of the heat sink 5, so that the insert 17 can be squeezed and deformed. The insert 17 slides against the inside of the slots 14, and the slots 14 limit the insert 17. The insert 17 slides against the outside of the limiting blocks 15, so that the insert 17 can be squeezed and deformed. Two limiting grooves 18 are opened on the outside of the insert 17. The limiting blocks 15 fit into the inside of the limiting grooves 18, so that the insert 17 can be limited, thereby limiting the heat sink 5.

[0031] After the heat sink 5 slides into the placement slot 2, it slides into the connecting block 16, which causes the insertion block 17 to be squeezed and deformed. Then, when the heat sink 5 is in contact with the inner wall of the connecting block 16, the insertion block 17 can perform a reset movement, which allows the insertion block 17 to fill the inside of the slot 14, and allows the limiting block 15 to be in contact with the inside of the limiting slot 18, thereby limiting the heat sink 5.

[0032] The working process of this utility model is as follows:

[0033] When the heat sink 5 needs to be installed, by moving the two pull blocks 12 to one side closer together, the pull blocks 12 pull the pull rope 10 inward, causing the pull rope 10 to cause the mounting plate 9 to compress the elastic element 11 and deform. This causes the mounting plate 9 to pull the locking block 4 into the mounting groove 8, at which point the heat sink 5 slides into the placement groove 2, allowing the support block 1 6 to slide into the support block 2 7, and the heat sink 5 to slide into the connecting block 16. This causes the insertion block 17 to be compressed and deformed. When the heat sink 5 is in contact with the inner wall of the connecting block 16, the insertion block 17 can perform a reset movement, thus allowing the insertion block 17 to... The heat sink 5 is contained within the slot 14, allowing the limiting block 15 to fit against the inside of the limiting groove 18, thus limiting the heat sink 5. At this time, by releasing the pull block 12, the elastic element 11 can perform a reset movement, thereby pushing the mounting piece 9 to move outward, so that the mounting piece 9 can push the locking block 4 to engage with the inside of the locking groove 3, thus allowing the heat sink 5 to be installed conveniently and stably, thereby facilitating the heat dissipation of the electronic components inside the housing 1, and facilitating the replacement of the heat sink 5. This not only results in high heat dissipation efficiency but also does not affect the efficiency of the transmitter, making it economical to use.
