Description

Technical Field

[0001] This invention relates to a lock base assembly, a hatch lock, and a locking device, belonging to the field of hatch lock technology. Background Technology

[0002] Helicopter cockpit door locking systems typically consist of a multi-point locking system with two or more door locks. Each door lock usually includes a lock base assembly and a lock housing assembly. To ensure accurate and smooth locking, and to provide adjustability, the position of the lock base relative to the lock housing needs to be adjusted to eliminate errors that may occur during installation or use.

[0003] In existing technologies, to achieve position adjustment of the lock seat in two directions, a split-type design is mainly used. This involves setting the lock seat into two movable parts, one of which is stacked on top of the other. One movable part can be adjusted in one direction, and the other in the other. However, the drawback of this method is that the increased structural components increase the height of the lock seat after installation, making it difficult to meet the space constraints of helicopters.

[0004] Therefore, in order to make the lock seat adjustable while reducing its installation height, a new locking device with an optimized structure is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a lock base assembly, a door lock, and a locking device that can reduce the installation height of the lock base.

[0006] This invention provides a lock seat assembly disposed within a hatch lock, for cooperating with a lock box assembly to lock the hatch lock, and features the following characteristics:

[0007] The lock seat body has two fixing parts, which are used to connect with the door frame of the hatch;

[0008] Two locking members are respectively disposed on the surfaces of the two fixing parts in a fitted manner. Each locking member is engaged with the corresponding fixing part via a toothed connecting part, the toothed connecting part having a plurality of toothed units; and

[0009] Two sets of fasteners are used to detachably secure the lock seat body and the two locking members to the door frame of the hatch.

[0010] In this configuration, several toothed units within the same toothed connecting portion extend in the same direction.

[0011] In one of the toothed connecting portions, several toothed units extend along a first direction, and in the other toothed connecting portion, several toothed units extend along a second direction. The first direction and the second direction are two mutually perpendicular directions within the same plane.

[0012] The lock seat body can be adjusted in position along the first direction and the second direction.

[0013] The lock base assembly provided by the present invention may also have the following features:

[0014] The toothed connecting portion includes:

[0015] The first toothed surface is formed by a plurality of toothed units disposed on the surface of the locking member that abut against the fixing part; and

[0016] The second toothed surface is formed by a plurality of toothed units disposed on the surface of the fixing part that abuts against the locking member.

[0017] The first tooth surface and the second tooth surface mesh with each other.

[0018] The lock base assembly provided by the present invention may also have the following features:

[0019] In this configuration, several tooth-shaped units within the first and second tooth-shaped surfaces are arranged adjacent to each other, and the cross-sectional dimensions of each tooth-shaped unit are consistent.

[0020] The lock base assembly provided by the present invention may also have the following feature:

[0021] The fastener is a threaded fastener, one end of which passes through the locking member and the corresponding fixing part in sequence and abuts against the surface of the locking member that is in contact with the fixing part, and the other end is used to extend into the door frame of the hatch and engage with it threadedly.

[0022] The fixing part has adjustment clearance holes extending through both ends in its height direction. The adjustment clearance holes extend along the first direction and the second direction. The fastener moves through the adjustment clearance hole on the corresponding fixing part. The adjustment clearance hole is used to make way for the fastener when the position of the lock body is adjusted.

[0023] This invention provides a hatch lock, disposed within a locking device, for locking the hatch, and characterized by comprising:

[0024] A lock seat assembly is provided on the door frame of the hatch, and it further includes a lock pin provided on the lock seat body;

[0025] A lock box assembly, disposed on the hatch and opposite to the lock seat assembly, for cooperating with the lock seat assembly to lock the hatch lock, comprising at least a lock hook for cooperating with the lock pin; and

[0026] A locking indicator component, disposed on the hatch and opposite to the lock box assembly, is used to indicate whether the hatch lock is properly locked.

[0027] The lock seat assembly is the lock seat assembly as described above.

[0028] The hatch lock provided by this invention may also have the following features:

[0029] The locking indicator component includes:

[0030] A base for connecting to the hatch;

[0031] A cover is disposed on the base and forms a rotation space therewith, the cover having an observation port communicating with the interior and exterior of the rotation space;

[0032] An indicator is rotatably supported on the base and located within the rotation space, either indirectly or directly; the indicator has a first indicator part and a second indicator part.

[0033] A driving lever, one end of which is connected to the locking hook and the other end of which is connected to the indicator, is used to drive the indicator to rotate from a first position corresponding to the first indicator portion and the observation port to a second position corresponding to the second indicator portion and the observation port; and

[0034] A reset element is used to drive the indicator to rotate from the second position to the first position after the driving force of the locking hook is removed.

[0035] When the locking hook rotates in the locking direction, it drives the indicator to rotate from the first position to the second position through the driving rod. When the locking hook rotates in the unlocking direction, the indicator rotates from the second position to the first position under the action of the reset member.

[0036] When the indicator is in the second position, the locking hook engages with the locking pin, and the hatch lock is locked in place.

[0037] The hatch lock provided by this invention may also have the following features:

[0038] The circumferential surface of the locking hook constitutes the driving part.

[0039] The drive rod slides through the base, with one end sliding into the rotation space and fixedly connected to the indicator, and the other end sliding into the lock box assembly and abutting against the drive part.

[0040] When the locking hook rotates along the locking direction, it pushes the driving rod to move to one side of the rotation space through the driving part, thereby driving the indicator to rotate;

[0041] As the locking hook rotates in the unlocking direction, it gradually removes the driving force applied to the drive rod.

[0042] The hatch lock provided by this invention may also include the following features:

[0043] A support shaft is fixedly supported on the base, and the indicator is rotatably supported on the support shaft;

[0044] The reset element is a torsion spring, which is sleeved on the support shaft, with one end abutting against the side wall in the rotation direction of the indicator element, and the other end abutting against the surface of the base.

[0045] When the locking hook rotates in the locking direction, the reset member compresses and stores force.

[0046] The hatch lock provided by this invention may also have the following features:

[0047] The lock box assembly further includes:

[0048] The lock box body has a receiving space for accommodating some components within the lock box assembly, and the receiving space has an opening on the side facing the lock base assembly; and

[0049] A movable panel is detachably installed at the opening of the accommodating space to close the opening of the accommodating space.

[0050] The present invention provides a locking device having the features of including the hatch lock as described above.

[0051] Therefore, the present invention has the following advantages compared with the prior art:

[0052] According to the lock seat assembly, hatch lock, and locking device of the present invention, the locking device includes a hatch lock, which includes a lock seat assembly, a lock box assembly, and a locking indicator assembly. The lock seat assembly includes a lock seat body, two locking members, and two sets of fasteners. Each locking member is engaged with a corresponding fixing part via a toothed connecting portion. The toothed connecting portion has several toothed units. When the position of the lock seat body needs to be adjusted, the two sets of fasteners are first loosened. Then, one locking member corresponding to the several toothed units extending in the second direction is separated from the corresponding fixing part. At this time, the operator can apply force to the lock seat body to move it in the first direction, thereby adjusting the position of the lock seat body in the first direction. After adjusting to the designated position, the locking member is reset to the corresponding fixing part. The locking element is engaged with the first locking element, and then a locking element corresponding to a number of toothed units extending along the first direction is separated from the corresponding fixed part. At this time, the operator can apply force to the locking body to move it along the second direction, thereby adjusting the position of the locking body in the second direction. During the movement of the locking body, it is always engaged with a locking element. The number of toothed units corresponding to the locking element can play a guiding and limiting role, so that the locking body can move accurately along the first or second direction, which helps to ensure the accuracy of adjustment. In addition, the toothed connection can effectively prevent the locking body from shifting after installation, thereby achieving stable installation of the locking body and reducing the number of structural parts in the locking assembly, so that the installation height of the locking body is lowered, which can meet the needs of limited space in helicopters.

Detailed Implementation

[0067] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the lock seat assembly, hatch lock and locking device of the present invention will be specifically described below with reference to the embodiments and accompanying drawings.

[0068] This embodiment provides a lock seat assembly, a door lock, and a locking device that can reduce the installation height of the lock seat.

[0069] Figure 1 This is a three-dimensional structural diagram of the locking device in an embodiment of the present invention.

[0070] like Figure 1 As shown, the locking device 100 of this embodiment includes a hatch lock 1, an unlocking drive assembly 2, and a handle assembly 3. The hatch lock 1 is mounted on the hatch and its frame. The unlocking drive assembly 2 is used to unlock the hatch lock 1. The handle assembly 3 is used to operate the unlocking drive assembly 2 to unlock the hatch lock 1.

[0071] Figure 2 This is a three-dimensional structural diagram of the door lock in an embodiment of the present invention.

[0072] like Figure 2 As shown, the hatch lock 1 includes a lock seat assembly 11, a lock box assembly 12, and a locking indicator assembly 13. The lock seat assembly 11 is mounted on the hatch frame and cooperates with the lock box assembly 12 to lock the hatch lock 1. The lock box assembly 12 is mounted on the hatch and opposite to the lock seat assembly 11, and cooperates with the lock seat assembly 11 to lock the hatch lock 1. The locking indicator assembly 13 is mounted on the hatch and opposite to the lock box assembly 12, and is used to indicate whether the hatch lock 1 is fully locked.

[0073] Figure 3 This is a three-dimensional structural diagram of the lock seat assembly in the first direction in an embodiment of the present invention.

[0074] like Figure 3 As shown, the lock seat assembly 11 includes a lock seat body 111, two locking members 112, and two sets of fasteners 114. The lock seat body 111 has two fixing parts 111a for connecting to the door frame of the hatch. The two locking members 112 are respectively disposed on the surfaces of the two fixing parts 111a in a fitted manner. Each locking member 112 is engaged with the corresponding fixing part 111a through a toothed connecting part 113, the toothed connecting part 113 having a plurality of toothed units 113a. The two sets of fasteners 114 are used to detachably fix the lock seat body 111 and the two locking members 112 to the door frame of the hatch. A plurality of toothed units 113a within the same toothed connecting portion 113 extend in the same direction. In one toothed connecting portion 113, the toothed units 113a extend in a first direction, while in another toothed connecting portion 113, the toothed units 113a extend in a second direction. The first and second directions are two mutually perpendicular directions within the same plane. The lock seat body 111 can be adjusted in position along the first and second directions.

[0075] Understandably, when it is necessary to adjust the position of the lock seat body 111, firstly, the two sets of fasteners 114 are operated to loosen them. Then, a locking member 112 corresponding to one of the toothed units 113a extending along the second direction is separated from the corresponding fixing part 111a. At this time, the operator can apply force to the lock seat body 111 to move it along the first direction, thereby realizing the adjustment of the position of the lock seat body 111 in the first direction. After adjusting to the specified position, the locking member 112 is reset and engaged with the corresponding fixing part 111a. Then, the locking member 112 corresponding to one of the toothed units 113a extending along the first direction is separated from the corresponding fixing part 111a. At this time, the operator can apply force to the lock seat body 111. This allows the lock seat body 111 to move along the second direction, thereby adjusting its position in the second direction. During the movement of the lock seat body 111, it is always engaged with a locking element 112. Several toothed units 113a corresponding to the locking element 112 can play a guiding and limiting role, enabling the lock seat body 111 to move accurately along the first or second direction, which helps to ensure the accuracy of adjustment. In addition, the toothed connecting part 113 can effectively prevent the lock seat body 111 from shifting after installation, thereby achieving stable installation of the lock seat body 111 and reducing the number of structural components inside the lock seat assembly 11, thus lowering the installation height of the lock seat body 111 and meeting the requirements of limited space in helicopters.

[0076] In this embodiment, the lock seat body 111 is installed on the hatch frame in a fitted manner, that is, the lower surface of the lock seat body 111 is fitted with the outer surface of the hatch frame, and the lock seat body 111 is moved along the surface direction of the hatch frame to adjust its position. The first direction and the second direction are two mutually perpendicular directions within the outer surface of the hatch frame, the first direction being the X direction of the outer surface of the frame, and the second direction being the Y direction of the outer surface of the frame.

[0077] like Figure 3 As shown, the lock seat assembly 11 also includes a lock pin 115 disposed on the upper end of the lock seat body 111. The lock pin 115 is used to cooperate with the lock box assembly 12 to achieve locking. Therefore, adjusting the position of the lock seat body 111 is actually to adjust the position of the lock pin 115 relative to the lock box assembly 12. Furthermore, lowering the installation height of the lock seat body 111 is actually to lower the height of the lock pin 115 so that the lock pin 115 can cooperate with the lock box assembly 12 to achieve locking.

[0078] In this embodiment, the two ends of the lock seat body 111 in the length direction constitute the fixing part 111a.

[0079] like Figure 3As shown, the toothed connecting part 113 includes a first toothed surface 113b and a second toothed surface 113c. A plurality of toothed units 113a disposed on the surface of the locking member 112 that fits against the fixing part 111a constitute the first toothed surface 113b, and a plurality of toothed units 113a disposed on the surface of the fixing part 111a that fits against the locking member 112 constitute the second toothed surface 113c. The first toothed surface 113b and the second toothed surface 113c mesh with each other.

[0080] Understandably, through the cooperation between the first toothed surface 113b and the second toothed surface 113c, the locking member 112 and the corresponding fixing part 111a are engaged and fitted together. When the two are engaged, under the locking action of the fastener 114, the locking member 112 achieves the limiting and fixing of the lock seat body 111 in the first and second directions, thereby achieving stable installation of the lock seat body 111 on the hatch frame. In addition, when the fastener 114 is in a loose state, the first toothed surface 113b and the second toothed surface 113c can slide relative to each other, allowing the fixing part 111a to move relative to the corresponding locking member 112 along the extension direction of the corresponding toothed unit 113a, thereby achieving the adjustment of the position of the lock seat body 111, while ensuring the accuracy of the adjustment and enabling rapid position adjustment.

[0081] like Figure 3 As shown, several toothed units 113a within the first toothed surface 113b and the second toothed surface 113c are arranged adjacent to each other, and the cross-sectional dimensions of each toothed unit 113a are consistent. Understandably, when the lock seat body 111 moves to different positions relative to the locking member 112, the first toothed surface 113b and the second toothed surface 113c can still engage with each other to achieve linear adjustment of the position of the lock seat body 111.

[0082] In this embodiment, the cross-sectional shape of the toothed unit 113a is an isosceles triangle or an equilateral triangle, and the width of a single toothed unit 113a is the minimum distance that the lock seat body 111 can adjust. The adjustable distance of the lock seat body 111 in the first direction and the second direction is an integer multiple of the width of a toothed unit 113a.

[0083] Figure 4 This is a three-dimensional structural diagram of the lock seat assembly in the second direction in an embodiment of the present invention; Figure 5 This is a three-dimensional structural diagram of the lock seat body in an embodiment of the present invention.

[0084] like Figure 4 and Figure 5As shown, the fastener 114 is a threaded fastener. One end of it passes through the locking member 112 and the corresponding fixing part 111a in sequence and abuts against the surface of the locking member 112 that is in contact with the fixing part 111a. The other end is used to extend into the door frame of the hatch and engage with it threadedly. The fixing part 111a has adjustment clearance holes 111b extending through both ends in its height direction. The adjustment clearance holes 111b extend along a first direction and a second direction. The fastener 114 moves through the adjustment clearance holes 111b on the corresponding fixing part 111a. The adjustment clearance holes 111b are used to make way for the fastener 114 when the position of the lock body 111 is adjusted.

[0085] Understandably, when one end of the fastener 114 abuts against the surface of the locking member 112 and the other end is threaded into the door frame of the hatch, the fastener 114 can fix the locking member 112 and the lock seat body 111 to the door frame of the hatch. When the fastener 114 is in a loose state, that is, when one end of the fastener 114 is disengaged from the surface of the locking member 112, the lock seat body 111 can move relative to the locking member 112. When the lock seat body 111 moves, the adjusting clearance hole 111b can make way for the fastener 114, so that the lock seat body 111 can be adjusted in position along the first direction and the second direction. At the same time, it is not necessary to remove the fastener 114 completely during the adjustment process, so as to achieve quick adjustment. Moreover, the fastener 114 in the loose state can restrict the locking member 112 from moving synchronously with the lock seat body 111, so as to achieve the guiding and limiting function of the lock seat body 111.

[0086] In this embodiment, the fastener 114 is a screw, which can be any one of a Phillips head screw, a slotted head screw, or an Allen head screw. In use, the head of the screw abuts against the upper surface of the locking member 112, and the tail of the screw extends into the door frame and engages with its threads. The door frame has a threaded hole for the tail of the screw to enter. When the screw is in a loose state, the head of the screw disengages from the upper surface of the locking member 112, while the tail of the screw remains in the threaded hole, thus limiting the locking member 112 during adjustment.

[0087] In this embodiment, the locking member 112 has a through hole through which the fastener 114 slides. Therefore, by applying force to the locking member 112 to make it slide upward along the fastener 114, it can be separated from the corresponding fixing part 111a, that is, the first toothed surface 113b and the second toothed surface 113c disengage. In this way, one of the locking members 112 can be separated from the corresponding fixing part 111a, thereby allowing the lock seat body 111 to move.

[0088] In this embodiment, the cross-sectional shape of the adjustment clearance hole 111b is rectangular, and its length and width directions correspond to the first direction and the second direction, respectively. There are four fasteners 114, which pass through the same locking member 112 in pairs. Correspondingly, there are also four adjustment clearance holes 111b, with each fastener 114 passing through one adjustment clearance hole 111b.

[0089] Figure 6 This is a three-dimensional structural schematic diagram of the locking indicator component in an embodiment of the present invention; Figure 7 This is a partial three-dimensional structural diagram of the locking indicator component in an embodiment of the present invention.

[0090] like Figure 6 and Figure 7 As shown, the locking indicator assembly 13 includes a base 131, a cover 132, an indicator 134, a drive rod 135, and a reset member 136. The base 131 is used to connect to the hatch. The cover 132 is disposed on the base 131 and forms a rotation space 133 therewith. The cover 132 has an observation port 132a communicating between the inside and outside of the rotation space 133. The indicator 134 is indirectly or directly rotatably supported on the base 131 and located within the rotation space 133. The indicator 134 has a first indicator portion 134a and a second indicator portion 134b. One end of the drive rod 135 is drivenly connected to the locking hook 121, and the other end is connected to the indicator 134, for driving the indicator 134 to rotate from a first position corresponding to the first indicator portion 134a and the observation port 132a to a second position corresponding to the second indicator portion 134b and the observation port 132a. The reset member 136 is used to drive the indicator 134 from the second position to the first position after the driving force of the locking hook 121 is removed.

[0091] Understandably, when the locking hook 121 rotates in the locking direction, it drives the indicator 134 to rotate from the first position to the second position via the driving rod 135. When the indicator 134 is in the second position, the locking hook 121 engages with the locking pin 115, and the hatch lock 1 is locked in place. When the locking hook 121 rotates in the unlocking direction, the indicator 134 rotates from the second position to the first position under the action of the reset member 136. This allows the operator to determine whether the hatch lock 1 is locked in place by observing the indicator through the observation port 132a. When the second indicator 134b is observed through the observation port 132a, it indicates that the hatch lock 1 has been locked in place, thereby improving the safety of use.

[0092] In this embodiment, the first indicator 134a and the second indicator 134b are easily distinguishable, and the difference may be in color, shape, or markings. For example, in this embodiment, the outer surface of the first indicator 134a has a red coating, and the outer surface of the second indicator 134b has a green coating. In other alternative embodiments, the first indicator 134a has a specific shape, and the second indicator 134b has a shape different from that of the first indicator 134a.

[0093] In this embodiment, the cover 132 is a hemispherical shell, which is fixedly mounted on the base 131 and its opening is closed by the base 131. The indicator 134 is a spherical shape that matches the inner wall of the cover 132. The first indicator part 134a and the second indicator part 134b are arranged sequentially along the rotation direction of the indicator 134.

[0094] like Figure 7 As shown, the locking indicator assembly 13 also includes a support shaft 137, which is fixedly supported on the base 131, and the indicator 134 is rotatably supported on the support shaft 137. The reset member 136 is a torsion spring, which is sleeved on the support shaft 137, with one end abutting against the side wall in the rotation direction of the indicator 134, and the other end abutting against the surface of the base 131.

[0095] Understandably, when the locking hook 121 rotates in the locking direction, the reset member 136 compresses and stores force. Therefore, when the locking hook 121 rotates in the unlocking direction, the reset member 136 can drive the indicator 134 to rotate and reset from the second position to the first position.

[0096] Figure 8 This is a schematic diagram of the cooperation structure between the locking indicator component and the lock box component in an embodiment of the present invention.

[0097] like Figure 8 As shown, the lock box assembly 12 includes a lock hook 121 for cooperating with the lock pin 115. A portion of the circumferential surface of the lock hook 121 constitutes a drive part 121a. A drive rod 135 slides through the base 131, with one end sliding into the rotation space 133 and fixedly connected to the indicator 134, and the other end sliding into the lock box assembly 12 and abutting against the drive part 121a.

[0098] Understandably, when the locking hook 121 rotates in the locking direction, it pushes the driving rod 135 to move towards the inside of the rotation space 133 through the driving part 121a, thereby driving the indicator 134 to rotate from the first position to the second position; when the locking hook 121 rotates in the unlocking direction, it gradually removes the driving force applied to the driving rod 135, at which time the indicator 134 rotates back to the first position under the action of the reset member 136.

[0099] In this embodiment, the driving part 121a is curved, and the driving rod 135 passes vertically through the base 131, with one end being hemispherical. This end abuts against the driving part 121a, so that when the locking hook 121 rotates in the locking direction, the driving part 121a can drive the driving rod 135 to move towards the inside of the rotation space 133. Simultaneously, when the locking hook 121 rotates in the unlocking direction, the driving rod 135 will not interfere with the rotation of the locking hook 121. Figure 8 The direction indicated by B is the locking direction, and the opposite direction is the unlocking direction.

[0100] Figure 9 This is a three-dimensional structural diagram of the lock box assembly in an embodiment of the present invention; Figure 10 This is a schematic diagram of the cooperation structure between the lock box assembly and the lock seat assembly in an embodiment of the present invention.

[0101] like Figure 9 and Figure 10 As shown, the lock box assembly 12 also includes a lock box body 122 and a movable plate 123. The lock box body 122 has a receiving space 122a for accommodating some components within the lock box assembly 12, and the receiving space 122a has an opening on the side facing the lock seat assembly 11. The movable plate 123 is detachably disposed at the opening of the receiving space 122a to close the opening of the receiving space 122a.

[0103] Figure 11 This is a three-dimensional structural diagram of the handle assembly in the first direction in an embodiment of the present invention; Figure 12 This is a three-dimensional structural diagram of the handle assembly in the second direction in an embodiment of the present invention.

[0104] like Figure 11 and Figure 12As shown, the handle assembly 3 is driven to the lock hook 121 via the unlocking drive assembly 2, and is used to drive the lock hook 121 to rotate and disengage from the lock pin 115, thereby unlocking the door lock 1. The handle assembly 3 includes a handle disc 31, a handle shaft 32, an inner handle 33, an outer handle 34, a safety switch 35, a reset member 36, and a linkage member 37. The handle shaft 32 rotatably passes through the handle disc 31, with one end extending into the helicopter cabin and the other end extending outwards. The inner handle 33 is fixedly mounted at the end of the handle shaft 32 extending into the helicopter cabin. The outer handle 34 is fixedly mounted at the end of the handle shaft 32 extending outwards. The reset member 36 is mounted on the handle disc 31 and is used to drive the inner handle 33 or the outer handle 34 to rotate and reset after the external force is removed. The linkage member 37 is fixedly mounted on the handle shaft 32 and has a swing end 371, which is driven to the unlocking drive assembly 2. Understandably, when the inner handle 33 or the outer handle 34 is rotated, the linkage 37 is driven to rotate synchronously through the handle shaft 32. When the linkage 37 rotates, its swing end 371 provides power to the unlocking drive assembly 2, thereby causing the unlocking drive assembly 2 to unlock the hatch lock 1.

[0105] Figure 13 This is a three-dimensional structural diagram of the unlocking drive component in an embodiment of the present invention.

[0106] like Figure 13 As shown, the unlocking drive assembly 2 includes a sleeve 21 and a flexible rod 22. One end of the sleeve 21 forms a fixed support with the handle disc 31, and the other end forms a fixed support with the lock box body 122. The flexible rod 22 is movably inserted into the sleeve 21, with one end extending from one end of the sleeve 21 and drivingly connected to the lock hook 121, and the other end extending from the other end of the sleeve 21 and connected to the swing end 371 of the linkage 37. Understandably, when the linkage 37 rotates, its swing end 371 pulls the lock hook 121 to rotate via the flexible rod 22, causing it to disengage from the lock pin 115, thereby unlocking the hatch lock 1. In this embodiment, the flexible rod 22 is a steel wire rope.

[0107] In this embodiment, there are two hatch door locks 1. The two hatch door locks 1 are linked to lock and unlock. One hatch door lock 1 is provided with a locking indicator component 13, while the other hatch door lock 1 is only provided with a lock seat component 11 and a lock box component 12. At the same time, there are also two corresponding unlocking drive components 2 and swing ends 371. The two swing ends 371 are respectively driven connected to the lock hooks 121 in the corresponding hatch door lock 1 through the corresponding unlocking drive components 2.

[0108] The role and effect of the embodiments

[0109] According to the lock seat assembly, hatch lock, and locking device involved in this embodiment, the locking device includes a hatch lock, which includes a lock seat assembly, a lock box assembly, and a locking indicator assembly. The lock seat assembly includes a lock seat body, two locking members, and two sets of fasteners. Each locking member is engaged with a corresponding fixing part via a toothed connecting part. The toothed connecting part has several toothed units. When the position of the lock seat body needs to be adjusted, the two sets of fasteners are first loosened. Then, one locking member corresponding to the several toothed units extending along the second direction is separated from the corresponding fixing part. At this time, the operator can apply force to the lock seat body to move it along the first direction, thereby adjusting the position of the lock seat body in the first direction. After adjusting to the designated position, the locking member is reset and engaged with the corresponding fixing part. The locking element is engaged with the first locking element, and then a locking element corresponding to a plurality of toothed units extending along the first direction is separated from the corresponding fixed part. At this time, the operator can apply force to the locking body to move it along the second direction, thereby realizing the adjustment of the position of the locking body in the second direction. During the movement of the locking body, it is always engaged with a locking element. The plurality of toothed units corresponding to the locking element can play a guiding and limiting role, so that the locking body can move accurately along the first or second direction, which helps to ensure the accuracy of adjustment. In addition, the toothed connection can effectively prevent the locking body from shifting after installation, thereby achieving stable installation of the locking body and reducing the number of structural parts in the locking assembly, so that the installation height of the locking body is reduced, which can meet the needs of the small space of helicopters.

[0110] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
