Abstract
Description
Technical Field
[0001] This application relates to the field of seismic acquisition technology for petroleum geophysical exploration, and in particular to a snap-on shell opening device. Background Technology
[0002] In the field of onshore seismic exploration, the G3iNXT is one of the mainstream instruments, with the acquisition station being its primary ground acquisition device. The acquisition station features a three-section, modular design, consisting of fixed connectors at both ends and a central housing. If the acquisition station is damaged internally, the fixed connectors must be separated from the central housing, disconnecting the connections between the two end connectors and the central housing, before the internal components can be removed for repair. The connection between the two end connectors and the central housing uses a snap-fit design, with no screws on the surface. Each fixed connector is secured to the central housing using six snap-fits. To separate the fixed connectors from the central housing, multiple snap-fits must be applied simultaneously and evenly to achieve successful separation. Because the snap-fits are very finely designed with few points of leverage, using conventional methods to apply force will easily damage the snap-fits and even the connection lines between the fixed connectors and the central housing.

Detailed Implementation
[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] In the field of onshore seismic exploration, the G3iNXT is one of the mainstream instruments, with the acquisition station being its primary ground acquisition device. The acquisition station features a three-section, modular design, consisting of fixed connectors at both ends and a central housing. If the acquisition station is damaged internally, the fixed connectors must be separated from the central housing, disconnecting the connections between the two end connectors and the central housing, before the internal components can be removed for repair. The connection between the two end connectors and the central housing uses a snap-fit design, with no screws on the surface. Each fixed connector is secured to the central housing using six snap-fits. To separate the fixed connectors from the central housing, multiple snap-fits must be applied simultaneously and evenly to achieve successful separation. Because the snap-fits are very finely designed with few points of leverage, using conventional methods to apply force will easily damage the snap-fits and even the connection lines between the fixed connectors and the central housing.
[0021] To address the aforementioned technical problems, this application provides a snap-on housing opening device that can assist workers in conveniently and safely opening the housing of the data acquisition station, protecting the data acquisition station, preventing damage to the housing, saving opening time, and improving worker efficiency.
[0022] The following is in conjunction with the accompanying drawings in the instruction manual. Figure 1 and Figure 2 A detailed explanation of the snap-on housing opening device is provided.
[0023] This application provides a snap-on housing opening device, which includes: a limiting component 1, including a limiting groove 11 and a limiting protrusion 12, with the limiting protrusion 12 provided on the inner surface of the limiting groove 11; a lifting component 2, disposed on the limiting component 1, including a transmission component 21 and a lifting component 22, the transmission component 21 being rotatably connected to the limiting component 1, the lifting component 22 being rotatably connected to the transmission component 21, and the lifting component 22 facing the limiting groove 11; and a pressing component 3, disposed on the limiting component 1, including a support frame 31 and a pressing protrusion 32, the support frame 31 being rotatably connected to the limiting component 1, and the pressing protrusion 32 being disposed at a position where the support frame 31 can perpendicularly face the limiting groove 11.
[0024] Specifically, the snap-on housing opening device includes: a limiting component 1, a lifting assembly 2, and a pressing component 3. The limiting component 1 includes a limiting groove 11 and a limiting protrusion 12. The snap-on housing is placed inside the limiting groove 11 to fix and limit the snap-on housing. The limiting protrusion 12 is provided on the inner surface of the limiting groove 11 to further limit the snap-on housing and reduce damage to it. The lifting assembly 2 includes a transmission component 21 and a lifting component 22. The lifting component 22 faces the limiting groove 11 to fix the snap-on housing. The lifting component 22 is rotatably connected to the transmission component 21 to achieve precise fixing of the snap-on housing. The moving part 21 is rotatably connected to the limiting part 1. By applying force to the transmission part 21, the transmission part 21 is driven to rotate. The transmission part 21 drives the lifting part 22 to rotate. The lifting part 22 applies a uniform, moderate, and accurate force to the snap-fit housing, avoiding damage caused by excessive local force. The pressing part 3 includes a support frame 31 and a pressing protrusion 32. The support frame 31 is rotatably connected to the limiting part 1. The pressing protrusion 32 is positioned so that the support frame 31 can perpendicularly face the limiting groove 11. The pressing protrusion 32 can limit the groove of the snap-fit housing, further fixing the snap-fit housing, reducing the risk of damage, and improving operational safety. The snap-fit housing opening device can help workers open the housing of the data acquisition station conveniently and safely, protecting the data acquisition station, avoiding damage to the housing, saving opening time, and improving the work efficiency of the workers.
[0025] Furthermore, the limiting groove 11 and the limiting protrusion 12 can be adjusted according to the size of the buckle, making them highly adaptable and suitable for delicate structures. When separating the buckle, the limiting groove 11 can more accurately align with the buckle, avoiding damage to the buckle or separation failure due to inaccurate positioning.
[0026] In some optional embodiments, the limiting component 1 further includes a base 13 and a limiting body 14. The base 13 is provided with a locking groove, the limiting body 14 is disposed in the locking groove of the base 13, and the limiting body 14 is provided with a limiting groove 11.
[0027] Specifically, the base 13 is tightly engaged with the limiting body 14 via a locking groove, ensuring a more stable overall structure for the limiting component 1. When separating the fixed joint and intermediate housing of the snap-fit housing, the snap-fit housing opening device can withstand greater external force without deformation, preventing uneven force application or operational failure due to structural instability. The limiting body 14 is mounted on the base 13 via the locking groove, forming a modular structure that facilitates disassembly and replacement. When repairing or replacing the limiting component 1, it is not necessary to replace the entire device; only the limiting body 14 or the base 13 needs to be replaced, reducing maintenance costs and time. The limiting body 14 directly features a limiting groove 11, and the snap-fit housing opening device is installed in the limiting groove 11. The limiting body 14 is precisely positioned via the locking groove of the base 13, ensuring more accurate position and dimensions of the limiting groove 11. The connection between the limiting body 14 and the base 13 via the locking groove reduces direct friction and wear. The base 13 provides stable support for the limiting body 14, making the position of the limiting groove 11 more fixed and eliminating the need for repeated adjustments during operation. As a supporting base, the base 13 can disperse external impact forces and protect the limiting body 14 and the limiting groove 11.
[0028] In some optional embodiments, the base 13 includes a base plate 132, a first locking plate 133, a second locking plate 134, and a fastening member 135. The first locking plate 133 and the second locking plate 134 are arranged face to face and spaced apart on the base plate 132 to form a locking groove. The fastening member 135 is disposed on the base plate 132 and presses against the second locking plate 134.
[0029] Specifically, the first locking plate 133 and the second locking plate 134 are arranged face-to-face at intervals to form a locking groove. The limiting body 14 is firmly locked between the two. At the same time, the fastening component 135 further fixes the limiting body 14 by pressing the second locking plate 134. During operation, the limiting body 14 will not loosen or shift, ensuring that the limiting groove 11 is always precisely aligned with the buckle, thus improving the reliability of the separation operation. The base plate 132 serves as a supporting foundation. The first locking plate 133 and the second locking plate 134 are arranged at intervals to form a rigid structure, which can effectively resist deformation caused by external forces. The first locking plate 133 and the second locking plate 134 can withstand large external forces without deformation, avoiding uneven force application or operation failure caused by structural deformation. The first locking plate 133 and the second locking plate 134 form a locking groove, allowing the limiting body 14 to be easily inserted or removed. Simultaneously, the fastening component 135 quickly secures the limiting body 14 by pressing against the second locking plate 134. This makes maintenance or replacement of the limiting body 14 more convenient, requiring no complex tools or procedures, saving time and labor costs. The fastening component 135, by pressing against the second locking plate 134, can adjust the width of the locking groove to accommodate limiting bodies 14 of different sizes, providing greater versatility and adaptability. It can be applied to different models of data acquisition stations or other similar equipment, expanding the applicability of the device.
[0030] In some alternative embodiments, a portion of the contact surface between the first locking plate 133 and the base plate 132 is fixedly connected to the base plate 132, and a portion is clearance-fitted with the base plate 132.
[0031] Specifically, the fixed connection ensures the stability between the first locking plate 133 and the base plate 132, while the clearance fit provides a certain amount of room for movement for the first locking plate 133. When the fastening component 135 presses against the first locking plate 133, the clearance fit allows the first locking plate 133 to undergo slight deformation, thereby better adapting to changes in the size of the limiting body 14. Simultaneously, the fixed connection ensures the stability of the overall structure. The clearance fit allows the first locking plate 133 to elastically deform inward when pressed by the fastening component 135, thus clamping the limiting body 14 more tightly. The limiting body 14 is firmly fixed in the locking groove, preventing loosening or displacement during operation and ensuring precise alignment between the limiting groove 11 and the buckle. The clearance fit disperses the stress between the first locking plate 133 and the base plate 132, preventing material fatigue or damage caused by localized stress concentration. The clearance fit gives the first locking plate 133 a certain elastic deformation capacity, enabling it to adapt to limiting bodies 14 of different thicknesses or sizes. The clearance fit allows the first locking plate 133 to be slightly adjusted outward when the limiting body 14 is installed, which facilitates the insertion and removal of the limiting body 14.
[0032] In some alternative embodiments, the fastening component 135 includes a fixing block 1351 and a fastening shaft 1352. The fixing block 1351 is disposed on the base plate 132 facing the first locking plate 133, and the fastening shaft 1352 extends through the fixing block 1351 toward the first locking plate 133. The fastening shaft 1352 is threadedly connected to the fixing block 1351.
[0033] Specifically, the fastening shaft 1352 and the fixing block 1351 are connected by threads, allowing precise control of the advance distance of the fastening shaft 1352. This enables precise adjustment of the compression degree of the first clamping plate 133. The clamping force can be flexibly adjusted according to the size and requirements of the limiting body 14, ensuring that the limiting body 14 is firmly fixed while avoiding damage caused by excessive compression. The fixing block 1351 serves as a supporting base, and the fastening shaft 1352 applies uniform compression force through the threaded connection. The threaded connection of the fastening shaft 1352 allows for the compression or release of the first clamping plate 133 simply by rotating the fastening shaft 1352, making the operation simple and intuitive. The threaded connection between the fastening shaft 1352 and the fixing block 1351 provides high mechanical strength and wear resistance, enabling it to withstand repeated adjustments and operations without easily being damaged. The fastening shaft 1352 and the fixing block 1351 are connected by threads, allowing for precise control of the advancing distance of the fastening shaft 1352. This enables precise adjustment of the pressure exerted on the first clamping plate 133, ensuring accurate force application during buckle separation and preventing damage or failure to separate the buckle due to uneven clamping or excessive pressure. The threaded connection has a self-locking characteristic, effectively resisting vibration and impact and preventing the fastening shaft 1352 from loosening during operation.
[0034] In some optional embodiments, the limiting body 14 includes a fixing plate 141, a first side plate 142 and a second side plate 143. The first side plate 142 and the second side plate 143 are arranged face to face and spaced apart on the fixing plate 141 to form a limiting groove 11. The fixing plate 141, the first side plate 142 and the second side plate 143 are all provided with limiting protrusions 12.
[0035] Specifically, the fixed plate 141 serves as the base, with the first side plate 142 and the second side plate 143 arranged face-to-face at intervals to form a stable limiting groove 11 structure. Simultaneously, the limiting protrusions 12 further enhance the rigidity of the side plates. During buckle separation, the limiting groove 11 can withstand significant external force without deformation, ensuring operational reliability and success rate. The limiting protrusions 12 on the first side plate 142 and the second side plate 143 can precisely engage with the buckle, ensuring its fixed position within the limiting groove 11. During buckle separation, the device can apply force precisely, preventing separation failure or damage due to buckle misalignment. The limiting protrusions 12 are evenly distributed on the fixed plate 141, the first side plate 142, and the second side plate 143, providing multi-directional buckle fixation and preventing slippage or detachment during operation. During buckle separation, the buckle is firmly fixed, ensuring uniform and stable force application and preventing separation failure due to buckle loosening. The design of the limiting protrusions 12 can be adjusted according to the size and shape of the buckle. The design of the limiting protrusion 12 allows the snap-fit housing to be quickly and accurately inserted into the limiting groove 11, while the structural stability of the limiting groove 11 ensures smooth operation. The tight fit between the limiting protrusion 12 and the snap-fit effectively resists vibration and impact, preventing the snap-fit from loosening or disengaging during operation.
[0036] In some alternative embodiments, the transmission component 21 and the pressing component 3 are disposed opposite to each other on the fixing plate 141 or the base plate 132 in the extension direction of the limiting groove 11.
[0037] Specifically, the length direction of the limiting groove 11 is the extension direction of the length of the first side plate 142 and the second side plate 143. The transmission component 21 and the pressing component 3 are arranged opposite each other along the extension direction of the limiting groove 11, which can evenly distribute the force application points along the length direction of the limiting groove 11, ensuring uniform force distribution during the separation process of the buckle, avoiding buckle damage or shell deformation caused by local stress concentration, and improving the success rate and safety of the separation operation. The opposite arrangement of the transmission component 21 and the pressing component 3 along the extension direction of the limiting groove 11 allows the buckle-type shell opening device to evenly distribute external force when subjected to force, avoiding local deformation. The opposite arrangement of the transmission component 21 and the pressing component 3 allows the user to precisely control the buckle separation process by adjusting the magnitude and direction of the force applied by the two components. When separating the buckle, the device can apply force precisely, avoiding buckle damage or separation failure caused by uneven force application. The opposite arrangement of the transmission component 21 and the pressing component 3 on both sides of the limiting component 1 allows the device to maintain stable performance in complex environments, such as on a seismic exploration site.
[0038] In some alternative embodiments, the transmission component 21 includes a first support and a handle 211. The first support is disposed on the fixed plate 141 or the base plate 132, and the handle 211 is rotatably connected to the first support.
[0039] Specifically, the first support part includes a first support plate 212 and a second support plate 213. The first support plate 212 and the second support plate 213 are arranged face-to-face and spaced apart on the support plate or base plate 132. The handle 211 is rotatably connected to the first support plate 212 and the second support plate 213. The arrangement direction of the first support plate 212 and the second support plate 213 is consistent with the arrangement direction of the first locking plate 133 and the second locking plate 134.
[0040] Furthermore, the handle 211 is rotatably connected to the first support plate 212 and the second support plate 213, allowing for easy application of force by rotating the handle 211. This makes operation more effortless and ergonomic, making it easier to separate the latches, reducing user fatigue, and improving the user experience. The rotatable connection design of the handle 211 allows users to precisely control the magnitude and direction of force by adjusting the rotation angle and force. When separating the latches, this avoids damage or failure to separate due to excessive or insufficient force, improving the accuracy and success rate of the operation. The first support plate 212 and the second support plate 213 are mounted on the support plate or base plate 132, providing a stable support foundation for the handle 211 and ensuring that the transmission component 21 does not shake or shift during operation.
[0041] In some alternative embodiments, the lifting component 22 includes a second support and a lifting element 221, the second support being disposed on the handle 211, and the lifting element 221 being rotatably connected to the second support.
[0042] Specifically, the second support portion includes a first rotating shaft 222, a third support plate 223, and a fourth support plate 224. The third support plate 223 and the fourth support plate 224 are located between the first support plate 212 and the second support plate 213, and are disposed on the handle 211. The first rotating shaft 222 connects the third support plate 223 and the fourth support plate 224. Two lifting elements 221 are provided, and the two lifting elements 221 are respectively disposed at both ends of the axial direction of the first rotating shaft 222.
[0043] Furthermore, the second support is fixed to the handle 211. When the handle 211 rotates, the second support rotates synchronously with the handle 211, providing a stable support base for the lifting element 221 and ensuring that the lifting component 22 does not shake or shift during operation. The lifting element 221 is rotatably connected to the second support. By adjusting the rotation angle and force, the lifting angle and applied force of the lifting element 221 can be precisely controlled. When separating the latch, damage to the latch or separation failure due to an excessively large or small lifting angle can be avoided, improving the accuracy and success rate of operation. The rotatable connection design of the lifting element 221 allows for easy control of the lifting action of the lifting element 221 by rotating the handle 211, making operation more effortless and ergonomic. The rotatable connection design of the lifting element 221 allows for precise control of the lifting angle and applied force of the lifting element 221 by adjusting the rotation angle and force.
[0044] In some alternative embodiments, the lifting element 221 is L-shaped or hook-shaped.
[0045] Specifically, the "L"-shaped or hook-shaped lifting element 221 can better conform to the shape of the buckle, increasing the contact area and ensuring uniform force application. When separating the buckle, the lifting element 221 can act more stably on the buckle housing, avoiding uneven force application or separation failure due to poor contact. The "L"-shaped or hook-shaped design allows the lifting element 221 to be precisely inserted into the gap or groove of the buckle, achieving precise force application. The "L"-shaped or hook-shaped design allows the lifting element 221 to flexibly adapt to buckles of different shapes and sizes, expanding the applicability of the device. The "L"-shaped or hook-shaped lifting element 221 can be quickly inserted into the gap or groove of the buckle, reducing operation steps and time.
[0046] In some optional embodiments, the support frame 31 includes a first support rod 311, a second support rod 312, and a second rotating shaft 313. One end of the first support rod 311 is connected to one end of the second support rod 312. The first support rod 311 and the second support rod 312 are perpendicular to each other. The second rotating shaft 313 connects the first side plate 142 and the second side plate 143. One of the first support rod 311 and the second support rod 312 is connected to the second rotating shaft 313. The other of the first support rod 311 and the second support rod 312 is provided with a pressing protrusion 32. The first support rod 311 or the second support rod 312 with the pressing protrusion 32 is provided with a handrail 33 to facilitate workers to apply pressure to the support frame 31.
