However, when a pair of lenses are optical lenses with different focusing parameters, such as a multi-light binocular thermal imaging device including a visible light lens and an infrared light lens, the two lenses cannot be focused simultaneously due to different focal lengths or different focal length adjustment ranges. Therefore, a focusing device is usually only provided for a single lens, which results in failure to achieve a good imaging effect. Summary of the invention

[0009] In one embodiment, the handheld assembly comprises: a first shift switch, which establishes or disconnects the connection between the focusing axis and the first transmission mechanism; and A second shift switch is used to establish or disconnect the connection between the focusing axis and the second transmission mechanism.

[0010] In one embodiment, the focusing axis includes a first focusing axis connected to the first transmission mechanism, and a second focusing axis connected to the second transmission mechanism, and the first focusing axis and the second focusing axis are coaxially arranged with an interval; The first focusing roller is movable along the axial direction of the focusing axis.

[0024] The embodiments of the present application provide a binocular handheld telescope, which can independently adjust the focal length of multiple optical imaging systems with different focusing parameters through focusing components.

[0025] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0026] First embodiment like Figure 1 As shown, one embodiment of the present application provides a binocular handheld telescope, comprising: A first lens barrel 10 and a second lens barrel 20, the first lens barrel 10 and the second lens barrel 20 are arranged side by side, wherein a first optical imaging system is installed in the first lens barrel 10, and a second optical imaging system is installed in the second lens barrel 20, and focusing parameters of the first optical imaging system and the second optical imaging system are different; A handheld assembly 30, the handheld assembly 30 is connected between the first lens barrel 10 and the second lens barrel 20; The handheld component 30 includes a focusing component 40, and the focusing component 40 adjusts the focal lengths of the first optical imaging system and the second optical imaging system independently of each other.

[0027] like Figure 1As shown. The telescope of this example adopts a common double-tube structure, wherein the first tube 10 and the second tube 20 are arranged side by side, wherein the first optical imaging system may, for example, include a first objective lens assembly 11 installed at the first end of the first tube 10 and a first eyepiece assembly installed at the second end of the first tube 10, and the second optical imaging system may include a second objective lens assembly 21 installed at the first end of the second tube 20 and a second eyepiece assembly installed at the second end of the second tube 20. Wherein, the objective lens assembly is arranged at the far end (first end) of the first tube 10 and the second tube 20, i.e., the side away from the operator's observation, and the eyepiece assembly is arranged at the near end (second end) of the first tube 10 and the second tube 20, i.e., the side observed by the operator through the eyepiece assembly. The handheld assembly 30 connects the first tube 10 and the second tube 20 as a whole, and provides a handheld position for the operator. In addition to providing the functions of connection and hand-holding, the handheld assembly 30 is also used to set an operation panel, such as a button 32, etc. Wherein, the handheld assembly 30 is adjacent to one side of the eyepiece assembly, which is convenient for personnel to operate.

[0028] The handheld assembly 30 includes a focus assembly 40 for adjusting the focal length of the objective lens assembly, and the focus assembly 40 can be implemented in the form of a focus roller. The number of the focus rollers can be one or two, which is less than or equal to the number of the objective lens assemblies. Regardless of whether the number of the focus rollers corresponds to the number of the objective lens assemblies, the focus rollers adjust the focal length of the objective lens assemblies one-to-one. That is, one focus roller only adjusts the focal length of one of the objective lens assemblies at the same time.

[0029] When the number of the focusing roller is one, the focusing roller can be used to adjust the focal lengths of the two objective lens assemblies independently of each other. When the number of the focusing assemblies 40 is two, the two focusing rollers are used to adjust the focal lengths of the two objective lens assemblies respectively. This solution can realize focal length adjustment of multiple optical imaging systems with different focusing parameters through a single focusing assembly, and can also realize focusing of two optical imaging systems respectively through dual rollers, and can realize focal length adjustment of multiple optical imaging systems with different focusing parameters through focusing devices with a number less than or equal to the number of lenses, so that optical systems in different lens barrels can be focused independently.

[0030] In this example, the first optical imaging system and the second optical imaging system have different focusing parameters. The focusing parameters may include but are not limited to the light-sensitive wavelength range, focal position, focal adjustment stroke, etc. of the objective lens assembly. Specifically, for example, the first objective lens assembly 11 is an infrared lens, and the second objective lens assembly 21 is a visible light lens.

[0031] Obviously, for optical lenses with different photosensitive wavelength ranges, it is impossible to adjust the focal length at the same time, so the focal length of the optical lenses needs to be adjusted separately.

[0032] Specifically, the handheld telescope of this embodiment includes: A first transmission mechanism 41, the first transmission mechanism 41 is connected to the first objective lens assembly 11, and the focusing assembly 40 adjusts the focal length of the first objective lens assembly 11 via the first transmission mechanism 41; and The second transmission mechanism 42 is connected to the second objective lens assembly 21 , and the focusing assembly 40 adjusts the focal length of the second objective lens assembly 21 via the second transmission mechanism 42 .

[0033] The focusing assembly 40 is arranged on the handheld assembly 30, and the handheld assembly 30 is adjacent to the near end of the first lens barrel 10 and the second lens barrel 20, and the objective lens assembly is arranged at the far end of the first lens barrel 10 and the second lens barrel 20. Therefore, the handheld telescope of the present embodiment further includes a transmission mechanism connected between the focusing assembly 40 and the objective lens assembly. Wherein, based on the principle of respectively performing focusing action on the objective lens assembly, the number of the transmission mechanisms and the objective lens assemblies in the present embodiment is one-to-one corresponding. Specifically, it includes a first transmission mechanism 41 connected to the first objective lens assembly 11 and a second transmission mechanism 42 connected to the second objective lens assembly 21, and the focusing assembly 40 adjusts the focal length of the first objective lens assembly 11 via the first transmission mechanism 41, and adjusts the focal length of the second objective lens assembly 21 via the second transmission mechanism 42.

[0034] In this example, the focusing assembly 40 includes a first focusing roller 401, which is selectively connected to one of the first transmission mechanism 41 and the second transmission mechanism 42 to adjust the focal length of the first objective lens assembly 11 and the second objective lens assembly 21 respectively.

[0035] That is to say, the first focusing roller 401 can only be connected to one of the first transmission mechanism 41 and the second transmission mechanism 42 at any time, so that only one of the first objective lens assembly 11 and the second objective lens assembly 21 can be adjusted at any time.

[0036] Specifically, the first focusing roller 401 is axially mounted on the focusing shaft 44, and the first focusing roller 401 synchronously drives the focusing shaft 44 to rotate axially; The focusing shaft 44 is alternatively connected to one of the first transmission mechanism 41 and the second transmission mechanism 42 .

[0037] In this example, the first focusing roller 401 drives the first transmission mechanism 41 or the second transmission mechanism 42 through the focusing shaft 44, and the first focusing roller 401 rotates synchronously with the focusing shaft 44, rather than rotating around the focusing shaft 44. For example, the first focusing roller 401 is fixed to the focusing shaft 44, and the first focusing roller 401 and the focusing shaft 44 are coaxially arranged.

[0038] In one specific example, the handheld assembly 30 includes: A shift switch 31 has a first gear position connected between the focus axis 44 and the first transmission mechanism 42 , and a second gear position connected between the focus axis 44 and the second transmission mechanism 42 .

[0039] The shift switch 31 serves as a connecting bridge between the focus shaft 44 and the two transmission mechanisms, and realizes the selective connection between the focus shaft 44 and the first transmission mechanism 41 and the second transmission mechanism 42. Specifically, the shift switch 31 may have two gears. When the shift switch 31 is in the first gear, the focus shaft 44 is connected to the first transmission mechanism 42 via the shift switch 31, and when the first focus roller 401 rotates in response to the external force of the operator, the focus shaft 44 is synchronously driven to rotate, so as to adjust the focal length of the first objective lens assembly 11 via the first transmission mechanism 42; when the shift switch 31 is in the second gear, the focus shaft 44 is connected to the second transmission mechanism 42 via the shift switch 31, and when the first focus roller 401 rotates in response to the external force of the operator, the focus shaft 44 is synchronously driven to rotate, so as to adjust the focal length of the second objective lens assembly 21 via the second transmission mechanism 42.

[0040] Optionally, in a specific example, the handheld component 30 includes: A first shift switch, which establishes or disconnects the connection between the focus axis 44 and the first transmission mechanism 42; and The second shift switch establishes or disconnects the connection between the focus axis 44 and the second transmission mechanism 42 .

[0041] In this example, two shift switches are included, each of which adjusts the connection relationship between the focus axis 44 and one of the transmission mechanisms. Specifically, the first shift switch is located between the focus axis 44 and the first transmission mechanism 42, and the first shift switch has a first position for establishing the connection between the focus axis 44 and the first transmission mechanism 42, and a second position for disconnecting the connection between the focus axis 44 and the first transmission mechanism 42. Similarly, the second shift switch is located between the focus axis 44 and the second transmission mechanism 42, and the second shift switch has a first position for establishing the connection between the focus axis 44 and the second transmission mechanism 42, and a second position for disconnecting the connection between the focus axis 44 and the second transmission mechanism 42.

[0042] The first shift switch and the second shift switch are located at opposite positions to realize the selective connection between the focus axis 44 and the first transmission mechanism 41 and the second transmission mechanism 42. For example, when the first shift switch is located at the first position, the second shift switch is located at the second position. Alternatively, when the first shift switch is located at the second position, the second shift switch is located at the first position.

[0043] The embodiment of the present application provides a binocular handheld telescope, which can realize the focal length adjustment of multiple optical imaging systems with different focusing parameters in different lens barrels through a focusing assembly. For optical imaging systems with different focusing parameters, the focal length of the optical lens is adjusted respectively. Wherein, based on the principle of focusing action for the objective lens assembly respectively, the number of transmission mechanisms and objective lens assemblies in this embodiment is one-to-one corresponding. Specifically, it includes a first transmission mechanism 41 connected to the first objective lens assembly 11 and a second transmission mechanism 42 connected to the second objective lens assembly 21, and the first focusing roller 401 adjusts the focal length of the first objective lens assembly 11 via the first transmission mechanism 41, and adjusts the focal length of the second objective lens assembly 21 via the second transmission mechanism 42.

[0044] Second embodiment like Figure 2a and Figure 2b As shown, one embodiment of the present application provides a binocular handheld telescope, comprising: A first lens barrel 10 and a second lens barrel 20, the first lens barrel 10 and the second lens barrel 20 are arranged side by side, wherein a first optical imaging system is installed in the first lens barrel 10, and a second optical imaging system is installed in the second lens barrel 20, and focusing parameters of the first optical imaging system and the second optical imaging system are different; A handheld assembly 30, the handheld assembly 30 is connected between the first lens barrel 10 and the second lens barrel 20; The handheld component 30 includes a focusing component 40, and the focusing component 40 adjusts the focal lengths of the first optical imaging system and the second optical imaging system independently of each other.

[0045] Wherein, the first optical imaging system may, for example, include a first objective lens assembly 11 installed at the first end of the first lens barrel 10 and a first eyepiece assembly installed at the second end of the first lens barrel 10, and the second optical imaging system may include a second objective lens assembly 21 installed at the first end of the second lens barrel 20 and a second eyepiece assembly installed at the second end of the second lens barrel 20. Wherein, the objective lens assembly is arranged at the far end (first end) of the first lens barrel 10 and the second lens barrel 20, that is, away from the side observed by the operator, and the eyepiece assembly is arranged at the near end (second end) of the first lens barrel 10 and the second lens barrel 20, that is, the side observed by the operator through the eyepiece assembly. The handheld assembly 30 connects the first lens barrel 10 and the second lens barrel 20 as a whole, and provides a handheld position for the operator. In addition to providing the functions of connection and handholding, the handheld assembly 30 is also used to set an operation panel, such as a button 32, etc. Wherein, the handheld assembly 30 is adjacent to one side of the eyepiece assembly, which is convenient for personnel to operate.

[0046] In this example, the first optical imaging system and the second optical imaging system have different focusing parameters. The focusing parameters may include but are not limited to the light-sensitive wavelength range, focal position, focal adjustment stroke, etc. of the objective lens assembly. Specifically, for example, the first objective lens assembly 11 is an infrared lens, and the second objective lens assembly 21 is a visible light lens.

[0047] Specifically, it includes: A first transmission mechanism 41, the first transmission mechanism 41 is connected to the first objective lens assembly 11, and the focusing assembly 40 adjusts the focal length of the first objective lens assembly 11 via the first transmission mechanism 41; and The second transmission mechanism 42 is connected to the second objective lens assembly 21 , and the focusing assembly 40 adjusts the focal length of the second objective lens assembly 21 via the second transmission mechanism 42 .

[0048] In this example, the focusing assembly 40 includes a first focusing roller 401, which is selectively connected to one of the first transmission mechanism 41 and the second transmission mechanism 42 to adjust the focal length of the first objective lens assembly 11 and the second objective lens assembly 21 respectively.

[0049] Specifically, the first focusing roller 401 is axially mounted on the focusing shaft 44, and the first focusing roller 401 synchronously drives the focusing shaft 44 to rotate axially; The focusing shaft 44 is alternatively connected to one of the first transmission mechanism 41 and the second transmission mechanism 42 .

[0050] The focusing shaft 44 includes a first focusing shaft 441 connected to the first transmission mechanism 41, and a second focusing shaft 442 connected to the second transmission mechanism 42, and the first focusing shaft 441 and the second focusing shaft 442 are coaxially arranged and spaced apart; The first focusing roller 401 is movable along the axial direction of the focusing shaft 44. The first focusing roller 401 has the following Figure 2a The first focusing position shown in FIG. 1 is engaged with the first focusing shaft 441 to synchronously drive the first focusing shaft 441 to axially rotate, and the first focusing position shown in FIG. Figure 2b The second focusing position shown is engaged with the second focusing shaft 442 to synchronously drive the second focusing shaft 442 to axially rotate.

[0051] The focus axis 44 includes a first focus axis 441 and a second focus axis 442 which are arranged at intervals. The first focus axis 441 and the second focus axis 442 are arranged along the same axial direction. The first focus roller 401 is movable along the axial direction of the focus axis 44, rather than along the physical focus axis 44. For example, the first focus roller 401 may be limited in an adjustment frame. In the radial direction, the first focus roller 401 is limited in position in the adjustment frame and has no freedom of movement. In the axial direction, the first focus roller 401 has freedom of movement, and the first focus axis 441 and the second focus axis 442 are respectively located at two ends in the axial direction. When the first focus roller 401 moves along the axial direction of the focus axis 44, it may be respectively engaged with the first focus axis 441 and the second focus axis 442 at two ends in the axial direction of the adjustment frame, so as to adjust the focal lengths of the first objective lens assembly 11 and the second objective lens assembly 21 via the first transmission mechanism 41 and the second transmission mechanism 42, respectively.

[0052] The embodiment of the present application provides a binocular handheld telescope, which can realize the focal length adjustment of multiple optical imaging systems with different focusing parameters in different lens barrels through a focusing assembly. For optical imaging systems with different focusing parameters, the focal length of the optical lens is adjusted respectively. Wherein, based on the principle of focusing action for the objective lens assembly respectively, the number of the transmission mechanism and the objective lens assembly in this embodiment is one-to-one corresponding. Specifically, it includes a first transmission mechanism 41 connected to the first objective lens assembly 11 and a second transmission mechanism 42 connected to the second objective lens assembly 21, and the focusing assembly 40 adjusts the focal length of the first objective lens assembly 11 via the first transmission mechanism 41, and adjusts the focal length of the second objective lens assembly 21 via the second transmission mechanism 42.

[0053] The first focusing roller 401 is movable along the axial direction of the focusing shaft 44. The focusing shaft 44 includes a first focusing shaft 441 connected to the first transmission mechanism 41 and a second focusing shaft 442 connected to the second transmission mechanism 42. The first focusing shaft 441 and the second focusing shaft 442 are coaxially spaced. The first focusing roller 401 is movable along the axial direction of the focusing shaft 44. The first focusing roller 401 has a first focusing position that is engaged with the first focusing shaft 441 to synchronously drive the first focusing shaft 441 to rotate axially, and a second focusing position that is engaged with the second focusing shaft 442 to synchronously drive the second focusing shaft 442 to rotate axially. The focal lengths of the first objective lens assembly 11 and the second objective lens assembly 21 are adjusted via the first transmission mechanism 41 and the second transmission mechanism 42, respectively.

[0054] Third embodiment like Figure 3 As shown, one embodiment of the present application provides a binocular handheld telescope, comprising: A first lens barrel 10 and a second lens barrel 20, the first lens barrel 10 and the second lens barrel 20 are arranged side by side, wherein a first optical imaging system is installed in the first lens barrel 10, and a second optical imaging system is installed in the second lens barrel 20, and focusing parameters of the first optical imaging system and the second optical imaging system are different; A handheld assembly 30, the handheld assembly 30 is connected between the first lens barrel 10 and the second lens barrel 20; The handheld component 30 includes a focusing component 40, and the focusing component 40 adjusts the focal lengths of the first optical imaging system and the second optical imaging system independently of each other.

[0055] Wherein, the first optical imaging system may, for example, include a first objective lens assembly 11 installed at the first end of the first lens barrel 10 and a first eyepiece assembly installed at the second end of the first lens barrel 10, and the second optical imaging system may include a second objective lens assembly 21 installed at the first end of the second lens barrel 20 and a second eyepiece assembly installed at the second end of the second lens barrel 20. Wherein, the objective lens assembly is arranged at the far end (first end) of the first lens barrel 10 and the second lens barrel 20, that is, away from the side observed by the operator, and the eyepiece assembly is arranged at the near end (second end) of the first lens barrel 10 and the second lens barrel 20, that is, the side observed by the operator through the eyepiece assembly. The handheld assembly 30 connects the first lens barrel 10 and the second lens barrel 20 as a whole, and provides a handheld position for the operator. In addition to providing the functions of connection and handholding, the handheld assembly 30 is also used to set an operation panel, such as a button 32, etc. Wherein, the handheld assembly 30 is adjacent to one side of the eyepiece assembly, which is convenient for personnel to operate.

[0056] In this example, the first optical imaging system and the second optical imaging system have different focusing parameters. The focusing parameters may include but are not limited to the light-sensitive wavelength range, focal position, focal adjustment stroke, etc. of the objective lens assembly. Specifically, for example, the first objective lens assembly 11 is an infrared lens, and the second objective lens assembly 21 is a visible light lens.

[0057] Specifically, it includes: A first transmission mechanism 41, the first transmission mechanism 41 is connected to the first objective lens assembly 11, and the focusing assembly 40 adjusts the focal length of the first objective lens assembly 11 via the first transmission mechanism 41; and The second transmission mechanism 42 is connected to the second objective lens assembly 21 , and the focusing assembly 40 adjusts the focal length of the second objective lens assembly 21 via the second transmission mechanism 42 .

[0060] In this example, the number of focusing rollers corresponds to the number of objective lens assemblies. The focus adjustment of the first objective lens assembly 11 by the first focusing roller 401 and the focus adjustment of the second objective lens assembly 21 by the second focusing roller 402 are independent of each other, the first focusing axis and the second focusing axis are arranged at intervals, and the first transmission mechanism and the second transmission mechanism are also independent of each other, therefore, the focus adjustment of the first objective lens assembly 11 and the second objective lens assembly 21 can be performed simultaneously, but the optical systems located in different lens barrels are adjusted independently of each other.
