Description

Technical Field

[0001] This utility model relates to the field of tools and implements, specifically to a tool for opening the rear cover of a transmitter. Background Technology

[0002] With the popularization of informatization and automation, various transmitters with different signals are increasingly used at natural gas production and transportation well stations to transmit various real-time data from the natural gas production and transportation well station back to the control center. Through analysis and processing, various calculation and control tasks are completed to ensure the safe and stable production of natural gas production and transportation well stations. On-site maintenance of transmitters is an important means to ensure the normal operation of various transmitters. However, the repair or calibration of various transmitters requires opening the rear cover of the transmitter first.

[0003] However, there is currently no tool specifically designed to open the transmitter's rear end cover. The main method currently used is to pry or push the rear end cover relative to the transmitter body to achieve opening. However, using this method to remove the cover for an extended period of time will damage the transmitter, affect its service life, and increase safety hazards at the well site. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, which currently lacks a dedicated tool for opening the rear cover of transmitters, and conventional opening methods can easily damage the transmitter, affect its service life, and increase safety hazards. This invention provides a tool for opening the rear cover of transmitters.

[0005] This utility model provides a tool for opening the rear cover of a transmitter, including: A housing, wherein a drive wheel is provided inside the housing, the drive wheel is connected to a drive shaft, the drive shaft extends out of the housing, and one end of the drive shaft extending out of the housing is connected to a handle; Two transmission blocks are arranged symmetrically in opposite directions within the housing, and the transmission blocks mesh with the drive wheel; A corner block is disposed at the end of the transmission block away from the drive wheel. The corner block extends out of the housing along a direction perpendicular to the central axis of the drive shaft. The corner block can engage with the rear cover of the transmitter.

[0006] This utility model discloses a transmitter rear end cover opening tool. By rotating the handle, the drive shaft rotates, which in turn moves the transmission block, thereby adjusting the distance between the two locking blocks. This allows the locking blocks connected to the transmission block to engage with the transmitter's rear end cover. When the handle is rotated in the opposite direction, the locking blocks can make tight contact with the transmitter's rear end cover. With the continued rotation of the handle, the transmitter's rear end cover can be removed, effectively avoiding damage to the transmitter during the disassembly and assembly of the rear end cover and reducing related risks.

[0007] Preferably, the corner block includes a connecting plate and a corner plate, the connecting plate connecting the transmission block and the corner plate, and the connecting plate extending out of the housing.

[0008] Preferably, the angle plate has a protrusion on its side near the connecting plate that nests with the rear end cover of the transmitter. The nesting of the protrusion with the rear end cover allows the angle plate to fit tightly against the rear end cover, enabling the rear end cover to rotate under external force.

[0009] Preferably, the corner plate has an anti-slip component on its side near the connecting plate. This further improves the contact stability between the corner plate and the rear end cover.

[0010] Preferably, the housing is provided with a slide rail, and the transmission block is provided with a slide groove, with the slide rail and the slide groove slidingly engaged. The slide rail and the slide groove can limit the movement direction of the transmission block, ensuring the movement direction of the two corner blocks.

[0011] Preferably, the transmission block includes an L-shaped driving part and an abutment part. The driving part has meshing teeth adapted to the driving wheel, and the abutment part has an abutment surface on one side and a clearance groove adapted to the driving wheel on the opposite side. The corner block is connected to the abutment surface. The abutment surface increases the contact area between the transmission block and the inner wall of the housing, improving the structural stability. The clearance groove extends the movable range of the corner plate.

[0012] Preferably, the drive shaft includes a rectangular rod-shaped structural member, and the drive wheel has a through hole adapted to the drive shaft. The rectangular rod-shaped structural member has a simple structure and can stably drive the drive wheel to rotate.

[0013] Preferably, the drive wheel has an annular groove, and the housing has a limiting member that extends into the housing and slides in conjunction with the annular groove. The limiting member can confine the drive wheel to a fixed position within the housing, preventing the drive wheel from disengaging from the transmission block.

[0014] Preferably, the housing includes a bottom shell and a top cover, which are detachably connected. This allows for easy opening of the top cover to facilitate the installation and maintenance of structures such as the drive wheel and transmission block.

[0015] Preferably, the cross-sectional shape of the shell is circular or rectangular.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a tool for opening the rear cover of a transmitter. By rotating the handle, the drive shaft is rotated, which in turn moves the transmission block. This allows for adjustment of the distance between the two corner blocks, so that the corner blocks connected to the transmission block can be engaged with the rear cover of the transmitter. 2. This utility model provides a tool for opening the rear cover of a transmitter. By rotating the handle in the opposite direction, the locking block can be made to make close contact with the rear cover of the transmitter. The rear cover of the transmitter can be removed by continuing to rotate the handle, which effectively avoids damage to the transmitter during the disassembly and assembly of the rear cover and reduces related risks.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0026] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0028] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0029] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0030] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0031] Example 1 like Figures 1-7 As shown, a transmitter rear cover opening tool includes a housing 1, a transmission block 5, and a locking block 6. The housing 1 is provided with a drive wheel 2, which is connected to a drive shaft 3. The drive shaft 3 extends out of the housing 1, and one end of the drive shaft 3 extending out of the housing 1 is connected to a handle 4. Two transmission blocks 5 are arranged symmetrically in opposite directions inside the housing 1. The transmission blocks 5 mesh with the drive wheel 2. The locking block 6 is located at the end of the transmission block 5 away from the drive wheel 2. The locking block 6 extends out of the housing 1 in a direction perpendicular to the central axis of the drive shaft 3. The locking block 6 can engage with the transmitter rear cover 9.

[0032] The housing 1 is the main body of the tool for opening the rear cover 9, and is used to house and install the drive wheel 2 and the transmission block 5. One end of the corner block 6 extends into the housing 1 and connects with the transmission block 5, and the other end extends out of the housing 1. The space between the two corner blocks 6 extending out of the housing 1 forms a space for engaging the rear cover 9 of the transmitter. The drive wheel 2 is set inside the housing 1 and meshes with the transmission block 5 for driving. The drive wheel 2 is driven to rotate by the drive shaft 3 extending out of the housing 1, which can drive the transmission block 5 that meshes with the drive wheel 2 to move, thereby changing the relative distance between the corner blocks 6 connected to the transmission block 5, and realizing the adjustment of the space between the two corner blocks 6 for engaging the rear cover 9 of the transmitter.

[0033] In an optional embodiment, the housing 1 may include a bottom shell 11 and a top cover 12, which are detachably connected. This allows for easy opening of the top cover 12 to facilitate the installation and maintenance of structures such as the drive wheel 2 and the transmission block 5.

[0034] In optional implementations, such as Figure 2 As shown, the cross-sectional shape of the housing 1 can be rectangular. The housing 1 can be fitted to the top surface of the rear end cover 9 and is engaged with the rear end cover 9 by two oppositely arranged corner plates 62.

[0035] In optional implementations, such as Figure 5As shown, the cross-sectional shape of the housing 1 can be circular. When the dimensions of the housing 1 are sufficient, the housing 1 can be embedded in the groove in the center of the rear cover 9 to achieve a stable fit between the opening tool and the rear cover 9, thereby improving the opening efficiency.

[0036] In an optional embodiment, the corner block 6 may include a connecting plate 61 and a corner plate 62. The corner plate 62 is arranged perpendicularly to the connecting plate 61. One end of the connecting plate 61 is connected to the transmission block 5, and the other end extends out of the housing 1 and is connected to the corner plate 62.

[0037] Alternatively, the connecting plate 61 and the corner plate 62 can be integrally formed structural components.

[0038] In optional implementations, such as Figure 1 , Figure 3 As shown, the side of the retaining plate 62 near the connecting plate 61 can be provided with a protrusion 63 that nests with the rear end cover 9 of the transmitter. In use, the protrusion 63 nests with the notch on the rear end cover 9 of the transmitter, which allows the retaining plate 62 to fit tightly with the rear end cover 9, which is beneficial for driving the rear end cover 9 to rotate under the external force of the rotating drive wheel 2.

[0039] In an optional embodiment, an anti-slip component 64 may be provided on the side of the corner plate 62 near the connecting plate 61.

[0040] In an optional embodiment, the anti-slip component 64 can be a vertical protrusion or a vertical groove. The extension direction of the vertical protrusion or vertical groove is perpendicular to the direction of the relative force between the corner plate 62 and the rear end cover 9, which helps to improve the contact stability between the corner plate 62 and the rear end cover 9 and prevents the corner plate 62 from sliding relative to the rear end cover 9 under the rotational force.

[0041] In optional implementations, such as Figure 2 , Figure 5 As shown, the transmission block 5 may include an L-shaped driving part 51 and an abutment part 52. The driving part 51 is provided with meshing teeth 511 adapted to the driving wheel 2. The abutment part 52 has an abutment surface 521 on one side and a clearance groove 522 adapted to the driving wheel 2 on the opposite side. The corner block 6 is connected to the abutment surface 521. The abutment surface 521 can increase the contact area between the transmission block 5 and the inner wall of the housing 1, improve the structural stability, and prevent the transmission block 5 from colliding with the inner wall of the housing 1 and affecting the movement direction of the transmission block 5. The clearance groove 522 can extend the movable range of the corner plate 62, allowing the abutment part 52 to move closer to the driving wheel 2.

[0042] In optional implementations, such as Figure 2 , Figure 5As shown, a slide rail 7 can be installed inside the housing 1, and a sliding groove can be installed on the transmission block 5. The slide rail 7 and the sliding groove are in sliding engagement. The movement direction of the transmission block 5 can be limited by the slide rail 7 and the sliding groove, thus ensuring the movement direction of the two corner blocks 6.

[0043] In an optional embodiment, the slide rails 7 corresponding to the two transmission blocks 5 are parallel to each other. When the drive wheel 2 drives the transmission block 5 to move, it can guide and limit the movement of the transmission block 5.

[0044] In an optional embodiment, the drive shaft 3 may include a rectangular rod-shaped structure, and the drive wheel 2 has a through hole adapted to the drive shaft 3. The rectangular rod-shaped structure is simple in structure and can stably drive the drive wheel 2 to rotate.

[0045] In an alternative embodiment, the drive shaft 3 may also be a polygonal rod-shaped structure with other numbers of edges.

[0046] In an optional embodiment, an annular groove 21 can be provided on the drive wheel 2, and a limiting member 8 can be provided on the housing 1. The limiting member 8 can extend into the housing 1 and slide in cooperation with the annular groove 21. The limiting member 8 can restrict the drive wheel 2 to a relatively fixed position within the housing 1, thereby preventing the drive wheel 2 from disengaging from the transmission block 5 when it rotates under external force.

[0047] This embodiment provides a transmitter rear cover opening tool. In use, the handle 4 drives the drive shaft 3 to rotate clockwise, causing the drive wheel 2 to rotate clockwise. This causes the two transmission blocks 5 to move away from each other, increasing the distance between the two corner blocks 6, which can then be engaged with the transmitter's rear cover 9. Then, the handle 4 is rotated counterclockwise, causing the drive wheel 2 to rotate counterclockwise, causing the two transmission blocks 5 to move towards each other, making the two corner blocks 6 fit tightly against the transmitter's rear cover 9. Continuing to rotate the handle 4 counterclockwise, the tight engagement between the corner blocks 6 and the rear cover 9 allows for the disassembly of the transmitter's rear cover 9.

[0048] This embodiment provides a transmitter rear cover opening tool. By rotating the handle 4, the drive shaft 3 rotates, which in turn moves the transmission block 5, thereby adjusting the distance between the two locking blocks 6. This allows the locking blocks 6 connected to the transmission block 5 to engage with the transmitter's rear cover 9. When the handle 4 is rotated in the opposite direction, the locking blocks 6 can make close contact with the transmitter's rear cover 9. With the continued rotation of the handle 4, the transmitter's rear cover 9 can be removed, effectively preventing damage to the transmitter during the disassembly and assembly of the rear cover 9 and reducing related risks.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
