Description

TECHNICAL FIELD

[0001] The utility model relates to a tool for disassembling a cover, in particular to a tool for disassembling a cover of a waterproof sealed box in a water-air dual-purpose aircraft. BACKGROUND

[0002] The water-air dual-purpose aircraft refers to a new unmanned aircraft capable of crossing the water-air interface multiple times and continuously navigating and repeatedly using. The water-air dual-purpose aircraft has the capabilities of underwater operation, water-air crossing and aerial cruising, and has broad application prospects in the fields of sea-air communication, search and rescue and underwater equipment maintenance.

[0003] The control device serves as the brain of the water-air dual-purpose aircraft and is responsible for the cooperative work of various components of the aircraft. However, as a power control system, the waterproof problem is a big challenge. Usually, the interference fit of the sealed box and the sealed cover is supplemented by a waterproof rubber ring to provide a dry space for the control system composed of a complete set of electronic components.

[0029] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.

[0030] In describing the present utility model, the "proximal end" is the end close to the operator, and the "distal end" is the end away from the operator. When one or more components are described as connected, joined, fixed, coupled, attached or otherwise interconnected, the interconnection can be a direct interconnection between the components, or can be an indirect interconnection, for example, interconnected by using one or more intermediate components.

[0031] Reference Figures 1 to 3 The present disclosure provides a tool 100 for disassembling a cover body, which can disassemble the cover body from a mounting piece. The cover body and the mounting piece adopt interference fit, which is inconvenient to disassemble directly without damage. The tool 100 can be used to disassemble the cover body from the mounting piece without damage. The disassembled cover body can be reused. The cover body and the mounting piece of the present disclosure are respectively illustrated by taking the cover body 220 and the box body 210 of the sealing box 200 as examples. It should be noted that the tool 100 provided by the present disclosure can also be used to disassemble other two assembled pieces with interference fit, such as the motor end cover (cover body) and the base (mounting piece).

[0032] The sealing box 200 includes the box body 210 and two cover bodies 220. The box body 210 is configured to include a housing that is closed on four sides and open at both ends. The housing extends in the longitudinal direction, and the two cover bodies 220 are arranged at both ends of the box body 210. Each cover body 220 is in interference fit with the box body 210. The box body 210 has an inner cavity, and the control device of the water-air dual-purpose aircraft can be sealed and stored in the sealing box 200.

[0033] Reference Figure 1The cross section of the shell of the box body 210 is configured as a circular ring, and the outer periphery of the box body 210 is provided with a plurality of circumferential longitudinal ribs 212 and a plurality of longitudinal transverse ribs 214. As a sealed box of a water-air dual-purpose aircraft, the water pressure problem when diving underwater needs to be considered, and the box body can be optimized in strength by arranging the longitudinal and transverse reinforcing ribs. Specifically, the outer periphery of the box body 210 is provided with four circumferential longitudinal ribs 212 arranged at equal intervals, for example, one longitudinal rib 212 is arranged on the upper and lower sides and both sides of the box body 210, respectively. The outer periphery of the box body 210 is provided with four longitudinal transverse ribs 214 arranged along the longitudinal direction, and the transverse ribs 214 can be configured as a complete ring. More specifically, in some embodiments, the two ends of the box body 210 are respectively provided with end protruding rings 216, and the outer contour of the cross section of the end protruding ring 216 is located outside the outer contour of the cross section of the shell of the box body 210.

[0034] In particular, the cover body 220 is provided with a connecting block 222 for connecting the tool 100, such as the sliding block 20 of the tool 100. The connecting block 222 is provided with a through hole for connecting the sliding block 20 by bolts or the like. Specifically, the cover body 220 is provided with two connecting blocks 222 arranged axially symmetrically on the cover body 220. Preferably, the connecting blocks 222 are arranged on both sides of the longer diagonal of the cover body plane to ensure the stability of the opening process.

[0035] Referring to Figure 2 and Figure 3 The tool 100 of the present disclosure includes a driving component 10, a sliding block 20, a fixing member 70, a first support seat 40a and a second support seat 40b. The fixing member 70 is detachably connected to the box body 210, and the sliding block 20 is detachably connected to the cover body 220; the driving component 10 includes a longitudinal screw rod 12, the sliding block 20 is provided with a screw hole 22 matched with the screw rod 12, and the screw rod 12 can extend through the screw hole 22. The first support seat 40a, the sliding block 20 and the second support seat 40b are arranged in sequence along the longitudinal direction, and the first support seat 40a is arranged on the side of the sliding block 20 close to the cover body 220. The first support seat 40a is connected to the fixing member 70, and the first support seat 40a is provided with a first mounting hole extending longitudinally and adapted to receive the screw rod 12, and the first mounting hole is configured as a blind hole or a through hole; the second support seat 40b is connected to the fixing member 70, and the second support seat 40b is provided with a second mounting hole extending through the second support seat 40b, and the screw rod 12 can extend through the second mounting hole.

[0036] When the first mounting hole is configured as a blind hole, the distal end of the screw rod 12 abuts against the first support seat 40a; when the first mounting hole is configured as a through hole, the tool 100 further comprises a first connecting plate 50, and the first support seat 40a is connected to the fixing member 70 through the first connecting plate 50, and the distal end of the screw rod 12 abuts against the first connecting plate 50. When the driving component 10 rotates towards the first direction, the sliding block 20 moves along the screw rod 12 towards the direction away from the first support seat 40a, and the cover 220 moves longitudinally relative to the box 210 to be separated from the box 210. When the cover 220 is separated from the box 210, the driving component 10 can also be driven to rotate towards the second direction, the sliding block 20 moves along the screw rod 12 towards the direction close to the first support seat 40a, and the cover 220 moves longitudinally relative to the box 210 to be mounted to the box 210. The first direction is opposite to the second direction, for example, the first direction is the clockwise direction when observed from the proximal end to the distal end, and the second direction is the counterclockwise direction when observed from the proximal end to the distal end.

[0037] The axis of the screw rod 12 is parallel to the axis of the sealed box 200, that is, the screw rod 12 and the sealed box 200 both extend longitudinally. The first support seat 40a and the second support seat 40b are both fixed to the fixing member 70, and the fixing member 70 is connected to the box 210, so the first support seat 40a, the second support seat 40b and the fixing member 70 are all connected to the box 210 as a whole, that is, they remain relatively static. When the cover 220 is removed from the box 210 by the tool 100, the two ends of the screw rod 12 are supported by the first support seat 40a and the second support seat 40b respectively. Since the first support seat 40a and the second support seat 40b remain static, the screw rod 12 can remain its axis parallel to the longitudinal direction when rotating, so that the sliding block 20 translates longitudinally, and then the sliding block 20 drives the cover 220 to translate longitudinally, which is beneficial to smoothly remove the cover 220. In addition, when the tool 100 is used for disassembly, the torque applied to the screw rod 12 can be continuously converted into the disassembly pulling force applied to the cover 220, which is convenient for disassembly.

[0038] Optionally, the driving component 10 comprises a handle 14 arranged at the proximal end of the screw rod 12, and the handle 14 is configured as a structure easy to hold, which is convenient for the person applying force to hold the handle 14 to apply torque to the screw rod 12. Specifically, the handle 14 is configured to comprise a plurality of rod bodies extending radially and connected to the proximal end of the screw rod 12, and the plurality of rod bodies are arranged at intervals in the circumferential direction. See Figure 3For example, the handle 14 is configured to include three rod bodies connected to the screw rod 12, the three rod bodies extend radially and the angle between two adjacent rod bodies is 120°. The user can easily disassemble the cover by rotating the radially elongated handle 14. Alternatively, the proximal end of the screw rod 12 can be configured to be connected to a tool such as a sleeve, and the user can disassemble the cover by connecting the sleeve to the proximal end of the screw rod 12. Optionally, the proximal end of the screw rod 12 can be coupled to or replaced by a power rotating mechanism.

[0039] The first mounting hole of the first support seat 40a is taken as an example of a through hole. In particular, in some embodiments, the first support seat 40a and the second support seat 40b are configured to have the same structure for the convenience of manufacturing. For the convenience of description, hereinafter, the first support seat 40a and the second support seat 40b having the same structure are referred to as a support seat. Continue to refer to Figure 2 and Figure 3 The support seat is configured as a plate, which is provided with a mounting hole 44 extending therethrough and extending longitudinally. The support seat is also provided with a connecting hole 42 connected to other components, such as the first connecting plate 50 or the second connecting plate 60 by a bolt or the like. In some embodiments, the mounting hole 44 is located in the middle of the support seat, and the connecting hole 42 is configured as two, which are respectively arranged on the opposite sides of the mounting hole 44. Optionally, the plate body surrounding the mounting hole 44 is thicker, and the thinned plate body is symmetrically arranged on the outer circumferential sides of the thicker plate body, and the connecting hole 42 is arranged on the thinned plate body. Optionally, in some embodiments, the support seat is provided with a bearing, and the screw rod 12 is connected to the support seat through the bearing. The bearing is arranged to facilitate reducing the friction when rotating.

[0040] Specifically, the tool 100 further includes a pull rod 104 and a connecting bracket 30, one end of the pull rod 104 is connected to the sliding block 20, the other end of the pull rod 104 is connected to the connecting bracket 30, and the connecting bracket 30 is connected to the cover 220. Among them, the pull rod 104 can uniformly apply the disassembling force to the cover 220 through the connecting bracket 30, which is conducive to the smooth movement of the cover 220 in the longitudinal direction. Continue to refer to Figure 2 and Figure 3The main body of the pull rod 104 is configured as a long strip, and the pull rod 104 is arranged on the upper side of the sliding block 20. The two sides of the proximal end of the pull rod 104 are respectively provided with an extension part, and the extension part is provided with a mounting hole. The pull rod 104 is connected to the sliding block 20 through the mounting hole arranged on the extension part by means of a bolt or the like. The pull rod 104 and the connecting bracket 30 are connected through a threaded connecting piece 103. Specifically, the distal end of the pull rod 104 is provided with a longitudinally extending threaded hole, the connecting bracket 30 is provided with a first hole 32, and the threaded connecting piece 103 extends through the second hole 34 and is connected to the pull rod 104. In some embodiments, the lower side of the pull rod 104 is provided with a receiving groove 105, which is adapted to accommodate the first connecting plate 50 and the first support seat 40a, and avoids interference between the pull rod 104 and the first connecting plate 50 and the first support seat 40a during the longitudinal movement of the pull rod 104.

[0041] The connecting bracket 30 is also provided with a plurality of second holes 34 for connecting to the cover 220. Specifically, the connecting bracket 30 can be configured in any suitable shape as long as it is suitable for connecting to the cover 220 and the pull rod 104. Alternatively, the connecting bracket 30 is configured in a U-shaped structure, both legs of the U-shaped structure are connected to the cover 220 (for example, corresponding to the two connecting blocks 222 connected to the cover 220), and the middle part of the U-shaped structure is provided with the first hole 32 for connecting to the pull rod 104. Among them, when disassembled, the center of the U-shaped structure is aligned with the center of the cover 220. That is, the center of the first hole 32 is aligned with the center of the U-shaped structure, and when disassembled, the center of the U-shaped structure is aligned with the center of the cover 220, so that the disassembly force can be uniformly applied to the cover 220. Specifically, the two legs of the U-shaped structure are respectively overlapped to the connecting blocks 222, and the two are fixed by means of a bolt. The connecting bracket 30 is connected to the connecting blocks 222 symmetrically arranged on both sides of the cover 220, and during the disassembly process, the two sides of the cover 220 and the box body 210 can be separated with the same relative displacement to open the sealed box 200, thereby avoiding the inclination of the cover 220 relative to the box body 210 during the opening process, which causes the relative angle between the cover 220 and the box body 210 to be stuck. The cover 220 is connected to the pull rod 104 through the U-shaped structure, which is equivalent to connecting the cover 220 to the pull rod 104 through two-point support. Alternatively, the cover 220 can also be connected to the pull rod 104 through three-point or four-point support.

[0042] Specifically, in some embodiments, the tooling 100 includes at least one first connecting rod 101, the first connecting plate 50 is connected to the fixture 70, for example, the end side wall of the fixture 70, through the at least one first connecting rod 101. Specifically, the tooling 100 further includes a second connecting plate 60 and at least one second connecting rod 102, the second connecting plate 60 is connected to the first connecting plate 50 through the at least one second connecting rod 102, and the second support seat 40b is fixed to the second connecting plate 60. The tooling 100 can be connected as a whole through the first connecting plate 50, the second connecting plate 60, the first connecting rod 101 and the second connecting rod 102, and the cover 220 can be supported by the tooling 100 when the cover 220 is removed.

[0043] Specifically, the first connecting plate 50 and the second connecting plate 60 are both configured as flat plates, and each of the first connecting plate 50 and the second connecting plate 60 is provided with a plurality of holes for connecting support seats, connecting rods and the like. In particular, the upper portion of the first connecting plate 50 is further provided with a pull rod hole 52, and the pull rod 104 extends through the pull rod hole 52 to be connected to the connecting bracket 30. The middle portion of the second connecting plate 60 is provided with a screw rod hole 62, and the screw rod 12 extends through the screw rod hole 62. Optionally, the first mounting plate 50 is arranged on the side of the first support seat 40a away from the sliding block 20, the second mounting plate 60 is arranged on the side of the second support seat 40b away from the sliding block 20, and the connecting bracket 30 is arranged on the side of the first mounting plate 50 away from the sliding block 20.

[0044] Optionally, the first connecting rod 101 and the second connecting rod 102 are both configured as an elongated column extending in the longitudinal direction, and are provided with threads at both ends. An easy-to-grip feature, such as a square portion, can be provided on the elongated body to facilitate gripping and fixing during installation. Preferably, the tooling 100 includes four first connecting rods 101 and four second connecting rods 102, the first connecting plate 50 is connected to the end side wall located at the lower portion of the fixture 210 through the four first connecting rods 101, and the second connecting plate 60 is connected to the first connecting plate 50 through the four second connecting rods 102.

[0045] Specifically, the fixture 70 can be configured in any shape as long as it is suitable for connection to the mounting member. Continuing to refer to Figures 1 to 3The fixing member 70 includes a housing 71 that is configured to be fitted to the cartridge 210 (mounting member). Specifically, the housing 71 extends in the longitudinal direction and is configured to be closed on the periphery and open at both ends, and an inner cavity 77 is formed in the housing 71. The inner cavity 77 is adapted to accommodate the cartridge 210. In some embodiments, the housing 71 is directly fixed to the cartridge 210, so that the housing 71 remains stationary when the drive member 10 rotates; in other embodiments, the housing 71 can abut against the cartridge 210 when the drive member 10 rotates in the first direction, so that the fixing member 70 remains stationary. Preferably, the inner side walls of both ends of the housing 71 are respectively provided with bosses 76, and when the fixing member 70 is mounted to the cartridge 210, the boss 76 located at the proximal end of the fixing member can abut against the end boss 216 located at the proximal end of the cartridge 210, which will facilitate disassembly of the cover 220.

[0046] Preferably, the inner side walls of the housing 71 are provided with longitudinal grooves 73 and transverse grooves 74, which are respectively configured to accommodate the longitudinal ribs 212 and the transverse ribs 214 provided on the periphery of the mounting member (cartridge 210). The provision of the longitudinal grooves 73 facilitates limiting the rotation of the housing 71 (i.e. the fixing member 70) about the axis, and the provision of the transverse grooves 74 facilitates limiting the longitudinal movement of the housing 71 (i.e. the fixing member 70).

[0047] Optionally, in order to facilitate the fitting of the fixing member 70 to the cartridge 210, the housing 71 is configured to be a structure enclosed by several parts, and the inner cavity 77 formed after the enclosure is adapted to accommodate the cartridge 210. Exemplarily, the housing 71 is configured to be a structure enclosed by two parts, specifically a first housing 71a and a second housing 71b that are divided into two. The inner side of the housing 71 can be milled to form a surface that conforms to the surface of the cartridge, and the protrusions of the reinforcing ribs (transverse ribs, longitudinal ribs) can be used as hard support to provide sufficient axial force, etc. to fix the bracket. Since the reinforcing ribs can be used as a medium for connecting the fixing member 70, the tool 100 does not need to add additional features to the cartridge for the fixation of the fixing member 70 to the cartridge 210.

[0048] Specifically, the two sides of the first housing 71a and the second housing 71b are respectively provided with lugs 72, and the lugs 72 are provided with holes, and the first housing 71a and the second housing 71b can be fixedly connected by bolts passing through the holes in the lugs 72. Optionally, the second housing 71b is arranged at the lower part of the first housing 71a, and four first connecting rods 101 are connected to the ends of the second housing 71b.

Next, the pull rod 104 is fixed to the sliding block 20, and then the sliding block 20 is placed between the first connecting plate 50 and the second connecting plate 60, and the distal end of the lead screw 12 extends through the second support seat 40b, the second support plate 60 and the sliding block 20 in sequence and is coupled to the first support plate 50. After connecting the connecting bracket 30 to the connecting block 222 of the cover 220, the connecting bracket 30 is connected to the pull rod 104 through the threaded connecting piece 103. Finally, the first shell 71a and the second shell 71b are installed to the box body 210 near the end of the cover 220 to be disassembled, and the first shell 71a and the second shell 71b are fixed by bolts and nuts to fix the fixing piece 70 to the box body 210. The fixing piece 70 clamps the surface of the box body 210 and the reinforcing ribs, so that the box body 210, the fixing piece 70, the two connecting plates and the two support seats can be regarded as a fixed and connected whole.

[0051] The person holding the handle 14 rotates the lead screw 12 in the first direction, and the sliding block 20 moves along the lead screw 12 in the direction away from the box body 210 (i.e. towards the proximal end of the lead screw 12) under the rotation of the lead screw 12, and the cover 220 moves longitudinally with the sliding block 20 and then separates from the box body 210. In summary, rotating the handle 14 can cause the cover 220 and the box body 210 to have a relative displacement in the axial direction of the lead screw, and the U-shaped connecting bracket 30 can keep the plane of the cover 220 perpendicular to the axis of the lead screw.

During disassembly, since the lead screw 12 is supported by the first support seat 40a and the second support seat 40b, the axis of the lead screw 12 remains parallel to the longitudinal direction when rotating, so that the sliding block 20 translates in the longitudinal direction, and then the sliding block 20 drives the cover body 220 to translate in the longitudinal direction, which is beneficial to the stable linear separation of the cover body and the mounting component. In addition, when the tool 100 is used for disassembly, the torque applied to the lead screw 12 can be continuously converted into the disassembly pulling force applied to the cover body 220, which facilitates disassembly.

[0053] In some embodiments of the present disclosure, the tool 100 further comprises a pull rod 104 and a connecting bracket 30, the pull rod 104 is connected to the sliding block 20, and the pull rod 104 can uniformly apply the disassembly pulling force to the cover body 220 through the connecting bracket 30, which facilitates the removal of the cover body 220. In some embodiments of the present disclosure, the tool 100 further comprises a first support plate 50, a second support plate 60, a first connecting rod 101 and a second connecting rod 102, which connect the tool 100 into a whole, and together constitute a simple and stable system.
