Description

Technical Field

[0001] The utility model relates to the field of imaging equipment, and more specifically, to an anti-retraction locking structure and imaging equipment. Background Art

[0002] Multi-module imaging devices are equipped with a variety of modules of varying specifications, and the appropriate module is selected and installed on the main unit as needed. For example, an imaging device with an audio and video camera as the main unit is equipped with an infrared zoom lens module and an infrared fixed-focus module. Either the infrared zoom lens module or the infrared fixed-focus module is selected and installed on the audio and video camera as needed. When connecting the modules to the main unit, they are typically secured to the main unit via an automatically retractable locking mechanism. To replace a module, the locking mechanism button must be manually pressed to release it. The button must be kept in the released position throughout the replacement process to remove the module for replacement, making the overall operation quite inconvenient. Utility Model Content

[0003] The present invention addresses the aforementioned issues by providing an anti-retraction locking structure. This structure uses an anti-retraction assembly to limit the movement of an elastic locking assembly, eliminating the need to continuously hold down the elastic locking assembly when removing the mounting module from the mounting slot, thereby facilitating removal of the mounting module. Furthermore, the anti-retraction locking structure is applied to imaging devices, facilitating the installation and replacement of fixed-focus or variable-focus infrared lens modules.

[0004] The utility model solves the above technical problems with the following technical solutions: an anti-retraction locking structure, comprising a mounting module and a mounting slot, wherein the mounting module is inserted into the mounting slot, and further comprising:

[0005] At least one set of elastic locking components, which are arranged on the installation slot body, and the installation module is provided with a limiting groove corresponding to the locking of the elastic locking components;

[0006] The elastic locking assembly is linked to an anti-retraction assembly, and the anti-retraction assembly is provided with a limit block. The installation module is provided with a first limit hole corresponding to the limit block at one end close to the bottom of the installation slot. Under the action of external force, after the lock is inserted into or moved out of the corresponding limit slot, the limit blocks respectively extend into the first limit holes.

[0007] The beneficial effect of the utility model is that the movement of the elastic locking assembly is limited by the anti-retraction assembly, so that when the installation module is removed from the installation slot, there is no need to keep pressing the elastic locking assembly, which facilitates the disassembly of the installation module.

[0008] Specifically, the installation module is inserted into the installation slot body. In order to fix the installation module in the installation slot body and prevent the installation module from falling off from the installation slot body, an elastic lock assembly is provided. The plugging and unplugging direction of the installation module is the first direction, and the lock of the elastic lock assembly moves along the second direction perpendicular to the first direction. Therefore, in the process of inserting the installation module into the installation slot body, the initial position of the lock is extended into the installation slot body. The installation module drives the lock to move and compresses the elastic part on the elastic lock assembly. When the installation module is fully inserted into the installation slot body, the elastic part returns to its original state, driving the lock to extend into the limit slot on the installation module. The elastic lock assembly is locked, thereby limiting the movement of the installation module in the first direction. When the installation module needs to be removed from the installation slot, an external force acts on the elastic lock catch assembly, driving it to move along the second direction, causing the lock catch to gradually move out of the limit groove. At the same time, the elastic member on the elastic lock catch assembly is compressed, and the anti-retraction assembly moves together with the corresponding elastic lock catch assembly. After the limit block on the anti-retraction assembly slides into the first limit hole, the external force on the elastic lock catch assembly is removed. At this time, although the elastic member exerts a force on the elastic lock catch assembly in the second direction, the first limit hole restricts the limit block, making the elastic lock catch assembly unable to move in the second direction. At this time, the installation module is not restricted by the two sets of elastic lock catch assemblies in the installation slot and can be easily removed. After the installation module is removed, the restriction of the elastic lock catch assembly in the second direction is lifted, and it begins to move under the force of the elastic member until the lock catch returns to its initial position.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows:

[0010] Furthermore, in the anti-retraction locking structure, the anti-retraction component includes:

[0011] A limiting rod is rotatably connected to the elastic lock assembly, the limiting block is arranged on the limiting rod, and a notch corresponding to the limiting block is provided on the bottom of the installation slot;

[0012] An elastic unit is provided between the limiting rod and the elastic locking assembly. Under the action of the elastic unit, the limiting rod rotates toward the notch so that the limiting block passes through the notch and extends into the first limiting hole.

[0013] The beneficial effect of adopting the above-mentioned further scheme is: in this further scheme, by arranging an elastic unit between the limit rod and the elastic locking assembly, the force of the elastic unit on the limit rod is exerted, and a pre-tightening force is applied to the limit rod, so that it drives the limit block to rotate toward the notch on the bottom of the installation slot body, so that the limit block elastically conflicts with the installation module and extends into the first limit hole.

[0014] Furthermore, in the anti-retraction locking structure, the elastic unit includes:

[0015] A rotating shaft, which is provided on the elastic lock assembly and is rotatably connected to the limiting rod, and a mounting opening is provided at the connection between the limiting rod and the rotating shaft;

[0016] A torsion spring is arranged in the installation opening and sleeved on the rotating shaft, and the torsion spring is respectively connected to the limiting rod and the elastic locking assembly.

[0017] The beneficial effect of adopting the above further solution is: in this further solution, the torsion spring applies force to the limit rod, so that one end of the limit rod provided with the limit block rotates toward the notch, so that the limit block elastically conflicts with the installation module.

[0018] Furthermore, in the anti-retraction locking structure, the anti-retraction component further comprises:

[0019] A stopper is connected to the mounting groove body, and when the limit block extends into the first limit hole, the limit rod contacts the stopper.

[0020] The beneficial effect of adopting the above-mentioned further scheme is: in this further scheme, in order to avoid the limit block applying force on the installation module and affecting the connection stability between the installation module and the installation slot when the limit block extends into the first limit hole or the second limit hole, an installation slot is set on the installation slot. When the limit block extends into the first limit hole or the second limit hole, the limit rod collides with the stop block. At this time, the limit block does not contact the inner wall of the first limit hole or the second limit hole, and thus will not apply force to the installation module.

[0021] Furthermore, in the anti-retraction locking structure, the elastic lock assembly includes:

[0022] a slide seat connected to the lock catch, wherein the mounting groove is provided with a slide hole corresponding to the lock catch, the lock catch slides through the slide hole, and the end thereof extending into the interior of the mounting groove is inclined;

[0023] a spring bracket connected to the mounting slot;

[0024] The locking spring has two ends connected to the slide seat and the spring bracket respectively.

[0025] The beneficial effect of adopting the above further solution is as follows: in this further solution, the lock catch slides within the sliding hole, and the direction of the sliding hole is set along the second direction, which can limit the movement trajectory of the slide seat, so that the lock catch slides along the second direction. At the same time, the lock catch adopts a wedge-shaped block, and its end that contacts the installation module is inclined to ensure that the lock catch can be gradually pushed into the sliding hole during the insertion of the installation module into the installation slot. At the same time, after the lock catch enters the limiting groove, the lock catch restrains the installation module when it is removed from the installation slot.

[0026] Furthermore, in the anti-retreat locking structure, the elastic locking component and the anti-retreat component are both arranged as two groups, the two groups of elastic locking components are arranged opposite to each other, and the installation module is provided with two limiting grooves corresponding to the locks of the two groups of elastic locking components, and the two groups of anti-retreat components are respectively linked with the two groups of elastic locking components.

[0027] The beneficial effect of adopting the above further solution is: in this further solution, two sets of elastic locking components are respectively provided at both ends of the installation module, so that when the installation module is inserted into the installation slot, the limitation of the installation module in the first direction is more stable.

[0028] The present utility model also provides an imaging device, comprising any of the above-mentioned anti-retraction locking structures, wherein the mounting groove is arranged on the host of the imaging device, and the fixed-focus infrared lens module or the zoom infrared lens module of the imaging device constitutes the mounting module.

[0029] The beneficial effect of adopting the above-mentioned further scheme is: in this further scheme, the anti-retraction locking structure is applied to the imaging device, and the mounting groove is set on the host of the imaging device, such as an audio and video camera, and a mounting interface or a through hole for the wiring harness to pass through is set on the bottom of the mounting groove. The fixed-focus infrared lens module and the zoom infrared lens module matched with the audio and video camera adopt the structure of the mounting module, so that the fixed-focus infrared lens module or the zoom infrared lens module can be quickly connected to the audio and video camera, and when replacing the fixed-focus infrared lens module or the zoom infrared lens module, there is no need to press the elastic lock assembly by hand, and the operation is more convenient.

[0030] Furthermore, in the imaging device, a driving mechanism connected to the elastic locking assembly is provided on the host of the imaging device.

[0031] The beneficial effect of adopting the above further solution is: in this further solution, by arranging a driving mechanism on the host of the imaging device, an external force acts on the driving mechanism to move the driving mechanism, and during the movement of the driving mechanism, the elastic locking assembly is driven to move synchronously with it.

[0032] Furthermore, in the imaging device, the driving mechanism is a lock switch, and a main body of the imaging device is provided with a strip-shaped through hole corresponding to the lock switch, and the lock switch is slidably arranged in the strip-shaped through hole.

[0033] The beneficial effect of adopting the above further scheme is: in this further scheme, the lock switch is connected to the outside of the host through the strip through hole, and the length direction of the strip through hole is the same as the direction of movement of the elastic lock assembly. The elastic lock assembly can be moved by pushing the lock switch by hand.

[0034] Furthermore, in the imaging device, an anti-slip strip is provided on the lock switch.

[0035] The beneficial effect of adopting the above further scheme is: in this further scheme, an anti-slip strip is provided on the lock switch. When the lock switch is pushed by hand, the fingers press on the anti-slip strip, which increases the friction between the fingers and the lock switch, making it easier to push the lock switch.

[0036] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0048] It should be noted that, in the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0049] Figure 1-Figure 5 An anti-retraction locking structure provided in an embodiment of the present invention includes an installation module 1 and an installation slot 2, wherein the installation module 1 is inserted into the installation slot 2, and further includes:

[0050] Two groups of elastic lock buckle 31 components are relatively arranged on the mounting groove body 2. A cavity for accommodating the elastic lock buckle 31 components is provided on the mounting groove body 2. Limiting grooves 11 corresponding to the lock buckles 31 of the elastic lock buckle 31 components are respectively provided at both ends of the mounting module 1; the elastic lock buckle 31 components include: a slide 32, which is connected to the lock buckle 31, and a sliding hole 22 corresponding to the lock buckle 31 is provided on the mounting groove body 2. The lock buckle 31 slides through the sliding hole 22, and the end thereof extending into the interior of the mounting groove body 2 is inclined; a spring bracket 33, which is connected to the mounting groove body 2; a lock buckle spring 34, whose two ends are respectively connected to the slide 32 and the spring bracket 33. The sliding direction of the slide 32 and the expansion and contraction direction of the lock spring 34 are both the same as the direction of the slide hole 22; the lock 31 is a wedge-shaped block, and its end in contact with the installation module 1 is inclined to ensure that the lock 31 can be gradually pushed into the slide hole 22 during the process of inserting the installation module 1 into the installation slot 2. At the same time, after the lock 31 enters the limit slot 11, the lock 31 restricts the installation module 1 when the installation module 1 is pulled out of the installation slot 2.

[0051] Two sets of anti-retraction components are respectively linked to the two sets of elastic lock components 31. The anti-retraction components include: a rotating shaft 43, which is mounted on the slide 32; a limiting rod 42 with a limiting block 41; a notch 21 corresponding to the limiting block 41 is provided at the bottom of the installation slot 2; and a first limiting hole 12 corresponding to the limiting block 41 is provided at one end of the installation module 1 near the bottom of the installation slot 2; a limiting rod 42, which is rotatably connected to the rotating shaft 43; a mounting opening is provided at the connection between the limiting rod 42 and the rotating shaft 43; a torsion spring 44 is disposed within the mounting opening and sleeved on the rotating shaft 43. The torsion spring 44 is respectively connected to the limiting rod 42 and the slide 32. Under the action of the torsion spring 44, the limiting rod 42 rotates toward the notch 21, allowing the limiting block 41 to pass through the notch 21 and extend into the first limiting hole 12. Under the action of external force, after the lock buckle 31 moves out of the corresponding limiting groove 11, the limiting blocks 41 extend into the first limiting holes 12. In addition, to prevent the installation module 1 from being inserted into the installation slot 2, and the limiting blocks 41 from exerting a force on the installation module 1 when the lock buckle 31 is inserted into the limiting groove 11, affecting the connection stability between the installation module 1 and the installation slot, a second limiting hole 13 corresponding to the limiting block 41 is provided at one end of the installation module 1 near the bottom of the installation slot 2. When the lock buckle 31 is inserted into the limiting groove 11, the limiting block 41 passes through the notch 21 and extends into the second limiting hole 13.

[0052] In the above embodiment, when the mounting module 1 is not inserted into the mounting slot 2, this is the initial position of the elastic lock catch 31 assembly and the anti-retraction assembly. The slide 32 moves toward the interior of the mounting slot 2 under the force of the lock catch spring 34 until it contacts the mounting slot 2, at which point the lock catch 31 extends into the mounting slot 2. As the slide 32 moves, the limit rod 42 moves along with it, and the limit block 41, under the force of the torsion spring 44, passes through the notch 21 on the bottom of the mounting slot 2 and extends into the mounting slot 2.

[0053] When the locking lever 32 is in the locked position, the locking lever 31 is in the locked position, and the locking lever 31 is in the locked position, so that the locking lever 31 is in the locked position, and the locking lever 31 is in the locked position, so that the locking lever 31 is in the locked position.

[0054] When the installation module 1 needs to be pulled out of the installation slot 2, a force is first applied to the slide 32 to move it away from the installation slot 2 and drive the lock 31 to move completely into the slide hole 22. At this time, the limit rod 42 moves together, and the limit block 41 on the limit rod 42 leaves the first limit hole 12 and slides into the second limit hole 13. At this time, the installation module 1 limits the limit block 41 in the second direction, that is, limits the sliding of the slide 32 in the second direction. Therefore, after the external force on the slide 32 is removed, the lock spring 34 applies a force to the slide 32, and the slide 32 remains stationary. In this way, the installation module 1 can be removed from the installation slot 2 without continuously applying a force to the slide 32. After the installation module 1 is removed, the limit of the limit block 41 by the installation module 1 in the second direction is cancelled, and the elastic lock 31 assembly and the anti-retraction assembly return to their initial positions.

[0055] Preferably, as another embodiment of the present invention, Figure 1-Figure 4 Based on the embodiment shown Figure 5 As shown, the anti-retraction component also includes:

[0056] The stopper 45 is connected to the mounting groove 2 . When the limiter 41 extends into the first limiter hole 12 or the second limiter hole 13 , the limiter rod 42 contacts the stopper 45 .

[0057] In the above embodiment, if Figure 2 and Figure 4 As shown in , a protrusion can be provided at the lower end of the mounting groove body 2 , and a stopper 45 is formed by the protrusion. The stopper 45 keeps the limiting rod 42 parallel to the sliding direction of the lock buckle 31 .

[0058] Preferably, as another embodiment of the present invention, Figure 1-Figure 4 The embodiment shown further includes multiple sets of connection components, through which the mounting module 1 is detachably connected to the mounting slot 2. The connection components include two magnets 5, which are respectively disposed in the mounting module 1 and the mounting slot 2.

[0059] In the above embodiment, the two magnets 5 of the same connecting assembly attract each other, thereby realizing the detachable connection between the mounting module 1 and the mounting slot 2 .

[0060] Preferably, as another embodiment of the present invention, guide posts 14 are respectively provided at both ends of the installation module 1 , and guide grooves 23 corresponding to the guide posts 14 are provided on the inner wall of the installation slot body 2 .

[0061] In the above embodiment, by providing a guide groove 23 on the inner wall of the installation slot body 2, when the installation module 1 is inserted into or pulled out of the installation slot body 2, the guide column 14 is guided by the guide groove 23, and the movement trajectory of the installation module 1 when inserted into or pulled out of the installation slot body 2 is limited to ensure the stability of the installation module 1 when inserted or pulled out.

[0062] The embodiment of the present utility model further provides an imaging device, such as Figure 6-Figure 8 As shown, including any of the above-mentioned anti-retraction locking structures, the mounting groove 2 is set on the host 61 of the imaging device, and the fixed-focus infrared lens module 62 or the zoom infrared lens module 63 of the imaging device constitutes the mounting module 1.

A mounting interface or a through hole for the wiring harness to pass through is set on the bottom of the mounting groove body 2. The fixed-focus infrared lens module 62 and the zoom infrared lens module 63 matched with the audio and video camera adopt the structure of the mounting module 1, so that the fixed-focus infrared lens module 62 or the zoom infrared lens module 63 can be quickly connected to the audio and video camera, and when replacing the fixed-focus infrared lens module 62 or the zoom infrared lens module 63, there is no need to press the elastic lock buckle 31 component by hand, and the operation is more convenient.

[0064] Preferably, as another embodiment of the present invention, a driving mechanism connected to the elastic locking assembly is provided on the host 61 of the imaging device.

[0065] In the above embodiment, a driving mechanism is provided on the host 61 of the imaging device, and an external force acts on the driving mechanism to move the driving mechanism, and during the movement of the driving mechanism, the elastic locking assembly is driven to move synchronously with it.

[0066] Preferably, as another embodiment of the present invention, the driving mechanism is a lock switch 35 , and a strip-shaped through hole 24 corresponding to the lock switch 35 is provided on the host 61 of the imaging device, and the lock switch 35 is slidably arranged in the strip-shaped through hole 24 .

At the same time, the length direction of the strip through hole 24 is the same as the direction of movement of the elastic lock assembly. The elastic lock assembly can be moved by pushing the lock switch 35 by hand.
