It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the accompanying drawings.

[0038] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense.

The first feature being "below", "below", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature.

[0040] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0041] As Figures 1-8As shown in the figure, this embodiment provides a tool for installing and disassembling a sealing plug, which is used to install the sealing plug 1 into the mounting hole of the fixed seat 2 and disassemble the sealing plug 1 from the mounting hole of the fixed seat 2. The tool for installing and disassembling the sealing plug includes a bracket 3, a pushing component 4 and a pushing-out component 5. In addition, in the present utility model, the sealing plug 1 is used to connect the execution unit at the upper end and the electronic control unit at the lower end of the measurement-while-drilling instrument. In order to facilitate connection, maintenance and replacement, and improve the connection reliability, welding cup pins 11 are provided at both ends of the sealing plug 1, and the outer part is integrally injection-molded with PEEK material to form sealing joints, namely a first sealing joint 12 and a second sealing joint 13, which can effectively prevent current leakage, ensure the safe operation of electrical equipment, and can be applicable to various high-pressure environments. The outer part of the sealing plug 1 is provided with a sealing groove, and an O-ring 14 and a PEEK retaining ring 15 are arranged in the sealing groove, which can effectively prevent liquid or gas leakage and ensure good sealing performance.

[0042] As Figure 1 shown in the figure, the bracket 3 is used to limit the fixed seat 2. The bracket 3 includes a supporting member 31, a first positioning member 32 and a second positioning member 33. The first positioning member 32 and the second positioning member 33 are fixedly arranged on the supporting member 31 by screws, and the first positioning member 32 and the second positioning member 33 are spaced apart along the axis direction of the mounting hole of the fixed seat 2. The first positioning member 32 and the second positioning member 33 jointly fix the fixed seat 2 to ensure that the fixed seat can remain stable when the sealing plug 1 is installed or disassembled, so that the installation and disassembly processes are more smooth.

[0043] The pushing component 4 is used to install the sealing plug 1 into the fixed seat 2. The pushing component 4 is arranged on the first positioning member 32. The pushing component 4 can move along the axis direction of the mounting hole of the fixed seat 2 towards the side close to the second positioning member 33. The output end of the pushing component 4 can abut against the pushing end of the sealing plug 1. By pushing the pushing component 4, the output end thereof pushes the sealing plug 1 into the fixed seat 2, which not only improves the installation efficiency but also prevents damage to the equipment.

[0044] In some embodiments, the pushing component includes at least one pushing rod 41. The pushing rod 41 is threadedly connected to the first positioning member 32 and abuts against the end face of the sealing plug 1 close to the first positioning member 32. By using a wrench to screw the pushing rod 41, the pushing rod 41 continuously feeds into the fixed seat 2, further pushing the sealing plug 1 into the fixed seat 2. Compared with the usual method of installing the sealing plug 1 by hammering, applying the pushing rod 41 to push in evenly has a more uniform force and better guarantees the maintenance of the equipment. Among them, as Figure 2As shown, the interior of the fixed seat 2 is a stepped hole. The end face of the fixed seat 2 away from the first positioning member 32 inside is the inner stepped end face 21. When the end face of the sealing plug 1 close to the second positioning member 33 fits against the inner stepped end face 21, it indicates that the sealing plug 1 is installed in place, thus ensuring the accurate installation position of the sealing plug 1 and improving the sealing performance. In addition, the surface of the fixed seat 2 that fits with the O-ring on the sealing plug 1 is the inner circular surface 22, and the inner circular surface 22 has relatively high requirements for the overall smoothness, which can effectively prevent liquid or gas leakage. Moreover, there are two fixing holes 24 symmetrically arranged at 180° on the outer circle of the fixed seat 2. After the sealing plug 1 is pushed into the assembly 4 and installed in place, screwing the screw 23 into the fixing hole 24 can achieve axial limitation of the sealing plug 1 and prevent the sealing plug 1 from loosening or falling off during use. In this embodiment, the number of pushing rods 41 is two, and different numbers of pushing rods 41 are within the protection scope of this embodiment as long as the sealing plug 1 can be smoothly pushed into the fixed seat 2.

[0045] In some embodiments, in order to make the force on the sealing plug 1 more uniform and smoother during pushing, the pushing assembly 4 includes at least one pushing rod 41 and a plugging member 42. The plugging member 42 passes through the first positioning member 32 and abuts against the pushing end of the sealing plug 1. The pushing rod 41 passes through the plugging member 42 and is threadedly connected to the first positioning member 32. Among them, the plugging member 42 is composed of a cylinder holder 421 and a plugging cylinder 422. The pushing rod 41 passes through the cylinder holder 421 and is threadedly connected to the first positioning member 32. The plugging cylinder 422 passes through the first positioning member 32 and abuts against the pushing end of the sealing plug 1. By screwing the pushing rod 41 to continuously screw it into the first positioning member 32, the plugging member 42 is simultaneously driven to continuously feed into the interior of the fixed seat 2. The annular end face of the plugging cylinder 422 abuts against the pushing end of the sealing plug, so that the entire end face of the sealing plug 1 can be uniformly stressed, thus ensuring the stability and smoothness of the sealing plug 1 when it is pushed. When the pushing end of the sealing plug 1 fits against the inner stepped end face 21, it indicates that the sealing plug 1 is installed in place, and then the screw 23 is screwed into the fixing hole 24 to achieve axial limitation of the sealing plug 1 and prevent the sealing plug 1 from loosening or falling off during use. In this embodiment, the number of pushing rods 41 is still selected as two. The two pushing rods 41 are stressed simultaneously, which can make the force on the sealing plug 1 more balanced and the installation process smoother.

[0046] As Figure 3 shown, the pushing-out assembly 5 includes a push rod seat 51 and a push rod. The push rod seat 51 is arranged on the side of the second positioning member 33 away from the first positioning member 32. In order to ensure that the pushing direction of the push rod is accurate and does not deviate, as Figure 8As shown, a first positioning hole 25 is provided at one end of the fixed seat 2 close to the second positioning member 33. At the same time, a second positioning hole 332 is provided on the second positioning member 33. The pushing rod is threadedly connected to the push rod seat 51, and the end of the pushing rod sequentially passes through the second positioning hole 332 and the first positioning hole 25 and then abuts against the pushing end of the sealing plug 1. When the sealing plug 1 needs to be removed from the fixed seat 2, first unscrew the screw 23 in the fixing hole 24 to unlock the axial limit of the sealing plug 1, and then use a wrench to screw the pushing rod, so that the pushing rod continuously feeds into the fixed seat 2, thereby pushing the sealing plug 1 out of the fixed seat 2.

[0047] Preferably, for the convenience of installation and disassembly of the pushing rod, the pushing rod is composed of two parts, namely a threaded section 52 and a smooth rod section 53. The threaded section 52 is threadedly connected to the push rod seat 51. One end of the smooth rod section 53 abuts against the threaded section 52, and the other end sequentially passes through the second positioning hole 332 and the first positioning hole 25 and then abuts against the pushing end of the sealing plug 1. When installing the pushing rod, there is no need to screw the pushing rod from the beginning at the push rod seat 51, and only this part of the threaded section 52 needs to be screwed. The surface of the smooth rod section 53 is smooth, so that it can be quickly inserted into the second positioning hole 332 and the first positioning hole 25, saving the time for installing the pushing rod and improving the disassembly efficiency of the sealing plug 1.

[0048] Preferably, in order to adapt to the narrow end face of the sealing plug 1, increase the contact area between the pushing rod and its end face, improve the stability of pushing, and at the same time to make the smooth rod section 53 have a certain strength, both the first positioning hole 25 and the second positioning hole 332 are semicircular, and the cross section of the smooth rod section 53 in the pushing rod is also semicircular.

[0049] Preferably, in order to improve the integrity of the sealing plug disassembly tooling and be able to disassemble the sealing plug more conveniently and stably, the push rod seat 51 is fixedly connected to one end of the supporting member 31 close to the second positioning member 33.

[0050] Furthermore, a protruding portion 311 is provided at one end of the supporting member 31 close to the second positioning member 33. The push rod seat 51 is fixedly connected to the end face of the protruding portion 311. The protruding portion 311 extends the distance between the push rod seat 51 and the fixed seat 2, leaving more feeding space for the threaded section 52 in the pushing rod, so that the sealing plug 1 can be completely pushed out of the fixed seat 2, and at the same time it is more convenient for the installation and disassembly of the pushing rod.

[0051] Preferably, to ensure that the mounting position of the fixing seat 2 on the bracket 3 is accurate, error-free, stable and reliable, a first positioning surface 26 is provided at one end of the fixing seat 2 that is pushed into the sealing plug 1, and a second positioning surface 27 is provided at the end of the fixing seat 2 that is pushed out of the sealing plug 1. A third positioning surface 321 is provided on the first positioning member 32, and a fourth positioning surface 331 is provided on the second positioning member 33. When the fixing seat 2 is positioned on the bracket 3, the first positioning surface 26 fits with the third positioning surface 321, and the second positioning surface 27 fits with the fourth positioning surface 331.

[0052] Operating steps of the sealing plug installation tooling:

[0053] Fix the first positioning member 32 and the second positioning member 33 to the supporting member 31, ensuring that the positioning plate is firmly installed and in the correct position;

[0054] Install the fixing seat 2 between the first positioning member 32 and the second positioning member 33. The first positioning surface 26 of the fixing seat 2 fits with the third positioning surface 321 of the first positioning member 32, and the second positioning surface 27 of the fixing seat 2 fits with the fourth positioning surface 331 of the second positioning member 33, ensuring that the installation position of the fixing seat 2 is stable and reliable;

[0055] Insert the sealing plug 1 into the fixing seat 2 from the side of the first positioning member 32. When encountering the resistance of the O-ring, pass the plugging member 42 through the first positioning member 32, making the end face of the plugging member 42 closely fit with the pushing end of the sealing plug 1;

[0056] Pass two pushing rods 41 through the cylinder holder 421 and thread them to the first positioning member 32. Use a wrench to simultaneously turn the two pushing rods 41, thereby driving the top cylinder 422 to smoothly push the sealing plug 1 forward until the pushing end of the sealing plug 1 contacts the inner step end face 21 of the fixing seat 2, indicating that the installation is in place;

[0057] Install the screw 23 into the fixing hole 24 of the fixing seat 2 using a wrench to achieve axial limit of the sealing plug 1.

[0058] Operating steps of the sealing plug disassembly tooling:

[0059] Fix the first positioning member 32 and the second positioning member 33 to the supporting member 31, ensuring that the positioning plate is firmly installed and in the correct position;

[0060] Remove the screw 23 from the fixing hole 24 of the fixing seat 2, and then install the fixing seat 2 with the sealing plug 1 between the first positioning member 32 and the second positioning member 33. Rotate the fixing seat 2 to ensure that the first positioning hole 25 on the fixing seat 2 is aligned with the second positioning hole 332 on the second positioning member 33;

[0061] Pass the smooth rod section 53 of the pushing rod through the through hole of the push rod seat 51, the second positioning hole 332, and the first positioning hole 25 in sequence, and abut against the pushing end of the sealing plug 1;

[0062] Fix the push rod seat 51 to the side end face of the protruding portion 311 of the supporting member 31 by screws to ensure that the push rod seat 51 is firmly installed and accurately positioned.

[0063] Screw the threaded section 52 of the ejector rod into the threaded hole of the push rod seat 51 and abut against the end face of the smooth rod section 53.

[0064] Continuously feed by screwing the threaded section 52 of the ejector rod with a wrench, so that the smooth rod section 53 continuously penetrates into the fixed seat 2, thereby gradually pushing the sealing plug 1 out of the fixed seat 2.

[0065] The sealing plug installation and disassembly tooling provided by the present utility model has a simple structure, is convenient to install and reliable to disassemble. Through the coordinated use of the bracket 3, the pushing assembly 4 and the ejecting assembly 5, the sealing plug 1 can be quickly and accurately installed into the installation hole of the fixed seat 2 and disassembled from the installation hole of the fixed seat 2. In practical applications, the tooling structure of the present utility model can greatly improve the installation and disassembly efficiency of the sealing plug, reduce the labor intensity, and at the same time ensure the integrity of the sealing plug and the fixed seat, having high practical value and popularization prospects.
