Description

A frequency insertion assembly for a combined logging tool Technical Field

[0001] This utility model relates to the field of frequency insertion assembly technology, and in particular to a frequency insertion assembly for a combined logging tool. Background Technology

[0002] A combined logging tool is a multi-purpose, high-efficiency logging device used in the exploration and development of resources such as oil and natural gas. It can provide reliable data support for formation evaluation and reservoir development. The plug-in assembly for the combined logging tool, also known as the connector for the combined logging tool, achieves reliable transmission of current or signals by inserting pins into the inside of the socket.

[0003] However, during the use of the combined logging tool, the cables or harnesses connected to it are often dragged. Most of the plug-in assemblies for the currently available combined logging tools are not securely connected, which makes the pins easy to move in the socket, resulting in poor contact of the cables or harnesses, or even breakage, affecting the normal use of the equipment.

[0004] Therefore, those skilled in the art have provided a frequency insertion assembly for a combined logging tool to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a frequency insertion assembly for a combined logging tool. By pressing the movable sleeve in the connecting mechanism, the blockage of the slider is released, allowing the slider to move within the groove and releasing the jamming state of the connecting block. Meanwhile, the elastic sheet acts on the movable sleeve to maintain the blockage of the slider, keeping the slider locked to the connecting block and improving the strength of the connection.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A frequency insertion assembly for a combined logging tool includes a insertion pin, a housing, and a connecting mechanism. The connecting mechanism is provided at the rear end of the insertion pin. The connecting mechanism includes a movable sleeve, a connecting block, and four sliders. An insertion hole is fixedly connected to the inner wall of the housing. A wire spring is fixedly connected to the front end of the inner wall of the insertion hole. Fixed blocks are fixedly connected to the four sides of the middle part of the outer wall of the housing. Receiving grooves are formed at the four sides of the rear end of the inner wall of the movable sleeve. Elastic plates are fixedly connected to the inner wall of the front end of the receiving groove. The rear end of the elastic plates is fixedly connected to the fixed blocks. The inner wall of the movable sleeve is slidably connected to the housing. Sliding grooves are formed at the four sides of the front end of the movable sleeve. The sliders slide inside the sliding grooves. The side of the slider near the center of the insertion hole penetrates the housing and is engaged with the connecting block. The side of the slider away from the center of the insertion hole penetrates the housing and fits against the movable sleeve.

[0008] The above technical solution releases the blockage of the slider by pressing the movable sleeve, allowing the slider to slide inside the groove when the pin is pulled. This releases the slider from the connecting block and allows the pin to separate from the socket. Meanwhile, the elastic sheet acts on the movable sleeve, keeping it in a blocking state on the slider, thus keeping the slider engaged with the connecting block and connecting the pin to the socket, thereby improving the strength of the connection.

[0009] Furthermore, the edge of the inner wall of the spring is chamfered, and the edge of the outer wall of the pin is chamfered.

[0010] The above technical solution utilizes a chamfer at the front edge of the inner wall of the spring and a chamfer at the rear edge of the outer wall of the pin to facilitate insertion of the pin into the spring, thus improving operational convenience.

[0011] Furthermore, a baffle is fixedly connected to the outer wall of the front end of the housing, and the inner wall of the connecting block is fixedly connected to the pin;

[0012] The above technical solution prevents the moving sleeve from moving excessively by fixing the baffle to the outer wall of the front end of the housing, and the connecting block is fixedly connected to the pin so that the pin is also locked after the connecting block is locked.

[0013] Furthermore, the edge of the inner wall of the baffle is chamfered at the front end, and the edge of the outer wall of the connecting block is chamfered at the rear end.

[0014] The above technical solution involves a chamfer at the front edge of the inner wall of the baffle and a chamfer at the rear edge of the outer wall of the connecting block, which allows the connecting block to be smoothly inserted into the outer shell under the action of the chamfer.

[0015] Furthermore, the fixing block is slidably connected to the receiving groove, and the inner wall of the wire spring is slidably connected to the insert pin;

[0016] Through the above technical solution, by sliding the fixed block and the receiving groove, the moving sleeve will not rotate on the outer shell, but can only move back and forth. The spring and the pin are slidably connected, so that the slider can be removed from the socket after it is released from the locking state of the connecting block. The pin and the socket are made of copper-plated gold material to improve oxidation resistance, while the outer shell is made of fluororubber material to improve insulation.

[0017] Furthermore, the upper and lower ends of the slider are both spherically convex, and the middle part of the outer wall of the connecting block is arc-shaped concave.

[0018] By employing the aforementioned technical solution, the lower end of the slider is made to have a spherical convex shape, while the middle part of the outer wall of the connecting block has an arc-shaped concave shape. This allows the pin to be pulled when the movable sleeve releases the blockage of the slider, easily releasing the slider from the jamming state of the connecting block. Furthermore, by making the upper end of the slider spherically convex, when the elastic sheet acts on the movable sleeve, the movable sleeve can easily compress the slider to move inside the groove, keeping the slider and the connecting block in a jamming state.

[0019] This utility model has the following beneficial effects:

[0020] This utility model proposes a frequency insertion assembly for a combined logging tool. By pressing the movable sleeve in the connecting mechanism and moving it towards the rear end of the outer shell, the blockage of the four sliders is released. This allows the sliders to slide inside the grooves when the insertion pin is pulled, releasing the locking state of the sliders against the connecting blocks fixed to the insertion pin, thus separating the insertion pin from the insertion hole. Meanwhile, the elastic plates inside the four receiving grooves act on the movable sleeve, keeping the movable sleeve in a blocking state against the sliders. This allows the four sliders to pass through the outer shell and remain locked to the connecting blocks fixed to the insertion pin, connecting the insertion pin to the insertion hole. This improves the connection's strength, prevents the connection from breaking when the cable or harness is dragged, and ensures the transmission of current or signals. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Referring to Figures 1-5, a specific embodiment of this utility model is provided: a frequency insertion assembly for a combined logging tool, including a insertion pin 1, a housing 3, and a connecting mechanism 4. The connecting mechanism 4 is provided at the rear end of the insertion pin 1. The connecting mechanism 4 includes a movable sleeve 401, a connecting block 405, and four sliders 407. An insertion hole 2 is fixedly connected to the inner wall of the housing 3. A wire spring 5 is fixedly connected to the front end of the inner wall of the insertion hole 2. Fixing blocks 402 are fixedly connected to all four sides of the middle part of the outer wall of the housing 3. Receiving grooves 40 are formed around the rear end of the inner wall of the movable sleeve 401. 3. The inner wall of the front end of the receiving groove 403 is fixedly connected with an elastic sheet 404. The rear end of the elastic sheet 404 is fixedly connected with the fixed block 402. The inner wall of the movable sleeve 401 is slidably connected with the outer shell 3. The movable sleeve 401 has a sliding groove 406 around the front end of the inner side. The slider 407 slides inside the sliding groove 406. The side of the slider 407 near the center of the insertion hole 2 passes through the outer shell 3 and is snapped into the connecting block 405. The side of the slider 407 away from the center of the insertion hole 2 passes through the outer shell 3 and fits against the movable sleeve 401.

[0030] By pressing the movable sleeve 401 in the connecting mechanism 4 to move towards the rear end of the outer casing 3, the blockage of the four sliders 407 is released, allowing the sliders 407 to slide inside the groove 406 when the pin 1 is pulled. This releases the locking state of the sliders 407 to the connecting block 405 fixedly connected to the pin 1, separating the pin 1 from the socket 2. Meanwhile, the elastic sheet 404 inside the four receiving grooves 403 acts on the movable sleeve 401, keeping the movable sleeve 401 in a blocking state on the sliders 407. This allows the four sliders 407 to pass through the outer casing 3 and remain locked to the connecting block 405 fixedly connected to the pin 1, connecting the pin 1 to the socket 2. This improves the strength of the connection, prevents the connection from breaking when the cable or wire harness is dragged, and ensures the transmission of current or signals.

[0031] The inner wall of the spring 5 has a chamfer at the front edge, and the outer wall of the pin 1 has a chamfer at the rear edge. The chamfer at the front edge of the inner wall of the spring 5, combined with the chamfer at the rear edge of the outer wall of the pin 1, allows the pin 1 to be easily inserted into the spring 5, improving operational convenience. A baffle 6 is fixedly connected to the outer wall of the front end of the housing 3, and the inner wall of the connecting block 405 is fixedly connected to the pin 1. The baffle 6 fixedly connected to the outer wall of the front end of the housing 3 prevents the moving sleeve 401 from moving excessively. The connecting block 405 is fixedly connected to the pin 1, so that when the connecting block 405 is locked, the pin 1 is also locked. The front edge of the inner wall of the baffle 6 is chamfered, and the rear edge of the outer wall of the connecting block 405 is chamfered. The chamfered edges of the inner wall of the baffle 6 and the rear edge of the outer wall of the connecting block 405 allow the connecting block 405 to be smoothly inserted into the outer shell 3. The fixing block 402 is slidably connected to the receiving groove 403, and the inner wall of the wire spring 5 is slidably connected to the pin 1. 402 is slidably connected to the receiving groove 403, so that the moving sleeve 401 will not rotate on the outer shell 3, but can only move back and forth. The wire spring 5 is slidably connected to the pin 1, so that the slider 407 can be removed from the socket 2 after it is released from the locking state of the connecting block 405. The pin 1 and the socket 2 are both made of copper-plated gold material to improve oxidation resistance, while the outer shell 3 is made of fluororubber material to improve insulation. The upper and lower ends of the slider 407 are spherically convex, and the middle part of the outer wall of the connecting block 405 is arc-shaped concave. By allowing the slider... The lower end of 407 is spherically convex, which, combined with the concave arc shape of the middle part of the outer wall of the connecting block 405, allows the pin 1 to be pulled when the movable sleeve 401 releases the blockage of the slider 407, easily releasing the slider 407 from the locking state of the connecting block 405. The upper end of the slider 407 is spherically convex, so that when the elastic plate 404 acts on the movable sleeve 401, the movable sleeve 401 can easily compress the slider 407 to move inside the slide groove 406, keeping the slider 407 and the connecting block 405 locked together.

[0032] Working principle: When using the plug-in assembly of this combined logging tool, the operator first presses the movable sleeve 401 backward to release the blockage of the slider 407. Then, the pin 1 connected to the end of the cable or harness is inserted into the spring 5 inside the socket 2, and the movable sleeve 401 is released. Under the action of the elastic plate 404, the movable sleeve 401 moves forward, blocking the slider 407 in the groove 406, thereby maintaining the slider 407 in the snap-fit ​​state of the connecting block 405, and firmly connecting the pin 1 to the socket 2, thus ensuring the combined logging tool can transmit current or signals using cables or harnesses.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
