Description

Technical Field

[0001] The present invention relates to the technical field related to cameras, and in particular to a camera that is easy to assemble. Background Art

[0002] Cameras are the cutting-edge component of a surveillance system, serving as the "eyes" of the entire system. They typically perform basic functions such as video recording / transmission and still image capture. After capturing an image through a lens, the camera's photosensitive circuitry and control components process the image and convert it into a digital signal that a computer can interpret. This signal is then transmitted to a computer via a parallel port or USB connection, where software then restores the image.

[0003] In the existing technology, the camera is mainly composed of a camera module, a control module and a shell. The shell is used to protect the internal camera module, control module and other structures. Therefore, the sealing of the shell is particularly important for protecting the performance and life of its internal components. Therefore, a sealing ring is often provided to ensure the waterproofness of the camera.

[0004] However, the following problems still exist in actual assembly: the shell is mostly composed of a front cover, a base shell and a rear cover, and the sealing ring is arranged between the front cover and the base shell and between the rear cover and the base shell. In the prior art, the front cover, the base shell and the rear cover are fixed by bolts, and it is difficult to control the locking force during assembly. If the locking force is too large, it will cause the pressure of the front cover and the rear cover on the sealing ring to increase, which may easily cause damage to the sealing ring. If the sealing ring cannot fit tightly with the sealing surface, the sealing effect will be deteriorated. Summary of the Invention

[0009] As a preferred technical solution of the present invention, the sealing airbag is connected to an inflation interface, and one side of the sealing airbag is provided with annular sealing protrusions in sequence from the inside to the outside.

[0010] As a preferred technical solution of the present invention, a vent hole is provided on the connecting cylinder, and the vent hole is used to communicate with the air storage airbag or the inflation interface.

[0011] As a preferred technical solution of the present invention, a through hole for slidingly cooperating with the transmission rod is provided on the annular packaging body, and the annular packaging body is connected to the supporting cylinder and the connecting cylinder.

[0012] As a preferred technical solution of the present invention, the support cylinder is provided with a plurality of mating grooves that can slide with the mating guide pillars. The mating grooves are composed of two locking grooves for locking the mating guide pillars and a movable groove for connecting the locking grooves.

[0013] As a preferred technical solution of the present invention, the camera module includes a supporting bracket, in which a zoom mechanism and a lens are installed, and a moving end of the zoom mechanism is detachably connected to the lens.

[0014] As a preferred technical solution of the present invention, several support columns are provided on both sides of the supporting bracket, and the support columns are detachably connected to the supporting bracket or the main control board through bolts. Several positioning rods are also provided on one side of the supporting bracket, and several positioning notches matching the positioning rods are opened on the main control board.

[0015] As a preferred technical solution of the present invention, a reserved hole is opened at the closed end of the front shell, and a protective lens is arranged in the reserved hole.

[0016] The beneficial effects of the present invention are: 1. This easy-to-assemble camera utilizes a threaded connection to assemble the front shell, the rear shell, and the base shell together. By moving the operating cylinder, the transmission rod can drive the annular extrusion plate close to the gas storage assembly. The annular extrusion plate squeezes the gas storage assembly, causing gas to flow into the sealing airbag, causing the sealing airbag to expand and fit tightly with the sealing surface to achieve sealing. This can effectively prevent the front shell and the rear shell from damaging the sealing airbag during assembly. The sealing airbag is inflated through the gas storage assembly, causing the sealing airbag to expand and fit tightly with the sealing surface to ensure sealing.

[0017] 2. This type of camera is easy to assemble, and the gas storage component is set as an air storage bag or an elastic air storage part. When the air storage bag is squeezed, the gas inside the air storage bag will enter the sealed air bag, causing the sealed air bag to expand. By moving the middle connecting part on the elastic air storage part, the deformation part is deformed, and the volume of the air storage cavity is reduced with the help of the deformation part. The gas in the air storage cavity will enter the sealed air bag, causing the sealed air bag to expand. Therefore, the manufacturer can flexibly select the air storage bag or the elastic air storage part as the air storage component according to actual conditions, which is conducive to meeting the different needs of users.

[0018] 3. This type of camera is easy to assemble, and the extrusion assembly is composed of an annular extrusion plate, a transmission rod, a return spring and an operating cylinder. The air storage bag can be squeezed by moving the annular extrusion plate to inflate the sealing air bag. The middle connecting part of the elastic air storage part needs to be connected to the annular extrusion plate. By moving the annular extrusion plate, the middle connecting part can be driven to deform the deformation part to inflate the sealing air bag. Therefore, the extrusion assembly can be well adapted to the air storage bag and the elastic air storage part, and has high versatility.

[0019] 4. This camera is easy to assemble, and the transmission rod can be limited by the provided annular matching groove. The existence of the annular matching groove enables the operating cylinder to rotate smoothly around the supporting cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] By rotating the operating cylinder 94, the matching guide column 943 moves from the locking groove 121 to the moving groove, and then the operating cylinder 94 is pushed in the direction close to the connecting cylinder 13. At this time, the matching guide column 943 moves from one end of the moving groove to the other end, and the transmission rod 92 is pushed by the operating cylinder 94 to put the return spring 93 in a stretched state. At the same time, the annular extrusion plate 91 is driven to approach the gas storage component 7 by the transmission rod 92, and the gas storage component 7 is squeezed by the annular extrusion plate 91, so that the gas flows into the sealing airbag 10, and finally the sealing airbag 10 is expanded and fits tightly with the sealing surface, thereby achieving Now the seal is formed, and then the operating cylinder 94 is rotated to move the matching guide column 943 from the moving groove to the other locking groove 121. The matching guide column 943 is locked by the locking groove 121 to complete the fixation of the operating cylinder 94, which can effectively prevent the front shell 1 and the rear shell 3 from causing damage to the sealing airbag 10 during assembly. The sealing airbag 10 is inflated through the air storage assembly 7 to expand the sealing airbag 10 and fit tightly with the sealing surface to ensure the sealing performance. The base shell 2 is connected to the front shell 1 and the rear shell 3 by a threaded connection, which is not only convenient for assembly, but also does not require the use of additional tools. In the process of moving the operating cylinder 94 to return to its original position, the elastic force of the reset spring 93 is used to drive the transmission rod 92, and the annular extrusion plate 91 is driven back to its original position by the transmission rod 92, so that the air storage component 7 is no longer squeezed. At this time, the gas in the sealing airbag 10 flows to the air storage component 7, and the sealing airbag 10 shrinks and returns to its original shape, detaches from the sealing surface, and releases the sealing state. After that, the front shell 1 and the rear shell 3 can be removed from the base shell 2. The extrusion component 9 can be applied to air storage airbags and elastic air storage parts, and therefore has high versatility.

[0029] In this embodiment, the transmission rod 92 can be limited by the provided annular matching groove 942 , and the existence of the annular matching groove 942 enables the operating cylinder 94 to rotate smoothly around the supporting cylinder 12 .

[0030] It should be noted that, in addition to the connection structure formed by the matching guide column 943 and the matching groove provided in this embodiment, a threaded connection can also be adopted between the operating cylinder 94 and the support cylinder 12. By rotating the operating cylinder 94, the operating cylinder 94 can be rotated and moved, so that the transmission rod 92 can slide in the through hole.

[0031] Among them, such as Figure 8 、 Figure 10 and Figure 11As shown, the elastic gas storage member is in a ring structure, and includes a middle connecting portion 73 and two fixing portions 72, the two fixing portions 72 are connected to the ring-shaped packaging body 4 and the supporting cylinder 12 respectively, the middle connecting portion 73 is connected to the ring-shaped extrusion plate 91, and the middle connecting portion 73 is provided with a deformation portion 71 on the inner and outer sides, the two ends of the deformation portion 71 are connected to the middle connecting portion 73 and the fixing portion 72 respectively, the elastic gas storage member can be made of metal material, or can be made of elastic material such as rubber and silicone rubber, compared with the elastic gas storage member made of rubber and silicone rubber, the elastic gas storage member made of metal material has longer service life in theory.

[0032] When the operating cylinder 94 is pushed towards the connecting cylinder 13, the ring-shaped extrusion plate 91 drives the middle connecting portion 73 to move into the gas storage cavity 8, the moving middle connecting portion 73 deforms the deformation portion 71, the deformation portion 71 reduces the volume of the gas storage cavity 8, and the gas in the gas storage cavity 8 enters the sealed air bag 10, so that the sealed air bag 10 is inflated and tightly adheres to the sealing surface, thereby realizing sealing, when the operating cylinder 94 is pushed away from the connecting cylinder 13, the ring-shaped extrusion plate 91 drives the middle connecting portion 73 to return to the original position, so that the elastic gas storage member returns to the original state, at this time, the gas in the sealed air bag 10 flows to the gas storage cavity 8, and the sealed air bag 10 is separated from the sealing surface, thereby releasing the sealing state.

[0033] In this embodiment, in order to fill the gas storage cavity 8 with gas, a gas filling pipe can be arranged on the fixing portion 72 on the outer side, and the gas filling pipe needs to penetrate the operating cylinder 94, in addition, when the sealed air bag 10 is not installed, the gas storage cavity 8 can also be filled with gas through the air hole 131.

The installation space formed between the annular packaging body 4 and the supporting cylinder 12 and the connecting cylinder 13 is used to install the gas storage assembly 7, and also provides space for the movement of the annular extrusion plate 91.

[0037] Among them, such as Figure 5 and Figure 6 As shown, the support cylinder 12 is provided with a plurality of mating grooves that can slide with the mating guide column 943.

The moving end of the zoom mechanism is detachably connected to the lens 52. The supporting bracket 51 is used to support the zoom mechanism and the lens 52. The zoom mechanism can be a voice coil motor or other embodiments. The specific structure of the zoom mechanism is not limited here.

After the front shell 1 and the rear shell 3 are respectively installed to the two ends of the base shell 2, the operating cylinder 94 is rotated to make the matching guide post 943 move from the locking groove 121 into the movable groove, and then the operating cylinder 94 is pushed in the direction close to the connecting cylinder 13. At this time, the matching guide post 943 moves from one end of the movable groove to the other end, and the operating cylinder 94 pushes the transmission rod 92 to make the return spring 93 in a stretched state. At the same time, the transmission rod 92 drives the annular extrusion plate 91 close to the gas storage assembly 7, and the gas storage assembly 7 is squeezed by the annular extrusion plate 91, so that the gas flows into the sealing airbag 10, and finally the sealing airbag 10 is expanded and tightly fitted with the sealing surface to achieve sealing. After that, the operating cylinder 94 is continued to be rotated to make the matching guide post 943 move from the movable groove to the other locking groove 121, and the matching guide post 943 is locked by the locking groove 121, completing the fixation of the operating cylinder 94, and then completing the sealing between the base shell 2 and the front shell 1 and the rear shell 3; When disassembling the camera, in the process of moving the operating tube 94 to return to its original position, the elastic force of the reset spring 93 is used to drive the transmission rod 92, and the annular extrusion plate 91 is driven back to its original position through the transmission rod 92, so that the gas storage assembly 7 is no longer squeezed.
