Description

Technical Field

[0001] The utility model belongs to the technical field of data collector interfaces, and particularly relates to an anti-falling structure of a data collector interface. Background Art

[0002] In the process of intelligent measurement of drilling depth, it is necessary to connect the various sensors for detecting drilling depth to the interface of the data collector through connecting line connectors for data collection. However, the traditional data collector interface is prone to shaking or even falling off when connecting the connector, resulting in the loss of some data from the data collector and affecting the intelligent measurement accuracy of drilling depth.

[0003] At present, there is existing technology to protect the interface of the collector from falling off, such as the patent application with application number CN202420075461.4, which provides a mounting frame, a positioning rod, a reinforcement plate and a reinforcement rod. Rotating the positioning rod can drive the mounting frame to move downward, and the downward movement of the mounting frame can drive the reinforcement plate to move downward. When the reinforcement plate moves to the threaded rod, rotating the reinforcement rod can drive the reinforcement plate to move, and the reinforcement plate will squeeze the threaded rod so that the threaded rod can be more stably connected to the threaded hole. Although the above method can effectively prevent the joint and the interface from falling off, it is necessary to rotate multiple screws, which results in a longer anti-falling operation time for the joint and the interface.

[0026] like Figure 1-4 As shown, an anti-falling structure of the collector interface is provided. The collector body 100 is provided with an interface 200, and a connector 300 is detachably plugged into the interface 200. The plug-in method of the connector 300 and the interface 200 refers to the existing technology. The anti-falling structure includes a limiting ring plate 1 and a limiting sleeve 2.

[0027] like Figure 1-3 As shown, the limiting ring plate 1 is installed on the collector body 100 and is sleeved on the outside of the interface 200; normally, the surface of the interface 200 is flush with the surface of the collector body 100 or the outer end face of the interface 200 is slightly higher than the surface of the collector body 100, and the limiting ring plate 1 can be welded or bonded to the surface of the collector body 100, and the inner hole of the limiting ring plate 1 is adapted to the shape and size of the interface 200.

[0028] A limiting block 11 is provided on the end surface of the limiting ring plate 1 facing away from the collector body 100 , and a limiting gap 12 is formed between the limiting block 11 and the limiting ring plate 1 .

[0029] In this embodiment, the longitudinal section of the limit block 11 is L-shaped, and one end of the limit block 11 is connected to the outer peripheral surface of the limit ring plate 1, and the connection method is welding or integral molding; the shape of the limit block 11 projected to the end face of the limit ring plate 1 is arc-shaped.

[0030] like Figure 1 、 Figure 2 and Figure 4 As shown, the limiting sleeve 2 is connected to the outside of the joint 300; the limiting sleeve 2 is provided with an inserting plate 21; when the joint 300 is plugged into the interface 200 and the limiting sleeve 2 is rotated into place, the inserting plate 21 can be stuck in the limiting gap 12; that is, the limiting sleeve 2 can rotate together with the joint 300, thereby driving the inserting plate 21 to rotate into place, or the limiting sleeve 2 can rotate relative to the joint 300, thereby driving the inserting plate 21 to rotate into place, and the inserting plate 21 is inserted into the limiting gap 12. Under the action of the limiting block 11, the joint 300 is pulled and the joint 300 cannot fall off directly from the interface 200. When the joint 300 needs to be disengaged from the interface 200, the limiting sleeve 2 is rotated in the opposite direction so that the inserting plate 21 is completely disengaged from the limiting gap 12.

[0031] The present application sets the limiting ring plate 1 and the limiting sleeve 2, which will not affect the connection between the connector 300 and the interface 200, and can quickly prevent the connector 300 and the interface 200 from falling off; in addition, the limiting ring plate 1 and the limiting sleeve 2 of the present application can be directly installed on the traditional connector 300 and the interface 200, and have high adaptability.

[0032] In this embodiment, there are multiple limit blocks 11 and they are arranged around the interface 200; there are also multiple plug plates 21 and they are arranged around the limit sleeve 2. The distance between two adjacent limit blocks 11 is greater than or equal to the size of the plug plates 21 projected onto the end face of the limit ring plate 1, that is, after the plug plates 21 rotate in the opposite direction, they can be detached from between the two limit blocks 11 along the axial direction of the limit sleeve 2, thereby realizing the disassembly of the connector 300 and the interface 200; the number of limit blocks 11 is usually 2, 4 or 6.

[0033] In this embodiment, if Figure 1 and 2 As shown, when the connector 300 is inserted into the interface 200 and the connector 300 cannot rotate in the interface 200, that is, the connector 300 usually has multiple pins, the inner side of the limit sleeve 2 is rotated to connect the inner cylinder 22; the inner cylinder 22 is connected to the outside of the connector 300, and the connection between the inner cylinder 22 and the connector 300 can be achieved by bonding or by threaded connection; as an optional option, the limit sleeve 2 is a T-shaped structure, the inner hole of the limit sleeve 2 is a through hole, and the plug plate 21 is located at the large diameter end of the limit sleeve 2.

[0034] In some other embodiments, when the connector 300 is inserted into the interface 200 and the connector 300 can rotate in the interface 200, the limit sleeve 2 is fixedly connected to the outside of the connector 300, and the limit sleeve 2 can be installed on the outside of the connector 300 by bonding or threading (not shown in the figure).

[0035] In this embodiment, if Figure 2 As shown, at least one end face of the inserting plate 21 is provided with a spring head 3; the limiting block 11 is provided with a limiting hole 4 on the side facing the limiting ring plate 1 and / or the limiting ring plate 1 is provided with a limiting hole 4 on the side facing the limiting block 11, and the spring head 3 is adapted to the limiting hole 4 and movably engaged, that is, the spring head 3 and the limiting hole 4 are adapted one to one. If the spring head 3 is provided on one end face of the inserting plate 21, the limiting hole 4 is provided on the limiting block 11 or the limiting ring plate 1. If the spring head 3 is provided on both end faces of the inserting plate 21, the limiting hole 4 is provided on the opposite surfaces of the limiting block 11 and the limiting ring plate 1.

[0036] The limiting hole 4 is hemispherical, and the head of the spring head 3 is also hemispherical; under the action of external force, when the plug plate 21 is separated from the limiting gap 12, the spring head 3 can automatically separate from the limiting hole 4; the setting of the spring head 3 and the limiting hole 4 can ensure that the plug plate 21 is located in the limiting gap 12, thereby further ensuring the anti-falling effect of the interface 200 and the connector 300.

[0037] In this embodiment, the spring head 3 includes a movable clamp 31, a movable plate 32 and a telescopic spring 33. A cavity 211 is provided in the inserting plate 21. The cavity 211 is connected to an opening extending to the surface of the inserting plate 21. The opening can accommodate the movable clamp 31. The movable plate 32 is slidably connected in the cavity 211 and is connected to the bottom of the cavity 211 through the telescopic spring 33; the movable clamp 31 is fixed on the side of the movable plate 32 away from the telescopic spring 33, and the movable clamp 31 extends out of the surface of the inserting plate 21 under the elastic force of the telescopic spring 33 itself.

[0038] In some other embodiments, such as Figure 5 As shown, at least one end face of the plug-in plate 21 is provided with a first magnetic sheet 5, and the limit block 11 is provided with a second magnetic sheet 6 on the side facing the limit ring plate 1 or the limit ring plate 1 is provided with the side facing the limit block 11, and the first magnetic sheet 5 and the second magnetic sheet 6 can be adsorbed to each other; the first magnetic sheet 5 and the second magnetic sheet 6 are both strip-shaped or rectangular; the first magnetic sheet 5 and the second magnetic sheet 6 are adsorbed to each other, which can ensure that the plug-in plate 21 is located in the limit gap 12, thereby further ensuring the anti-fall-off effect of the interface 200 and the connector 300.

[0039] When in use, the connector 300 is inserted into the interface 200, and the limiting sleeve 2 is rotated to rotate the plug plate 21 into the limiting gap 12. Under the action of the limiting block 11, the connector 300 can be prevented from falling off from the interface 200; when the connector 300 needs to be disengaged from the interface 200, the limiting sleeve 2 is rotated in the opposite direction to disengage the plug plate 21 from the limiting gap 12. At this time, the connector 300 can be pulled out along the axial direction of the connector 300.
