The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0041] The elongated rod mechanism provided by the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] Please refer to Figure 1 and Figure 2 , Figure 1 is a front view of the elongated rod mechanism in one embodiment of the present application, Figure 2 is a rear view of the elongated rod mechanism in one embodiment of the present application. One embodiment of the present application discloses an elongated rod mechanism 100, which comprises a sliding plate 10, an elongated rod 20, and a mounting plate 30. Among them, the sliding plate 10 is slidably arranged on the cross beam of the automobile calibration equipment; one end of the elongated rod 20 is detachably connected to the sliding plate 10, and the other end of the elongated rod 20 extends in a direction away from the sliding plate 10 to form a mounting portion 210; the mounting plate 30 is detachably connected to the mounting portion 210, and the mounting plate 30 is configured to be able to mount the AVM laser instrument assembly 40 of the automobile calibration equipment.

[0043] Through the above structure, the sliding plate 10 is slidably arranged on the cross beam, the extension rod 20 is arranged on the sliding plate 10, the mounting plate 30 is arranged on the extension rod 20, and the AVM laser instrument assembly 40 is mounted on the mounting plate 30. When the equipment beyond the original calibration range is accurately calibrated, the sliding plate 10 can be slid relative to the cross beam, so that the extension rod 20 and the AVM laser instrument assembly 40 extend out of the cross beam, thereby the calibration range of the AVM laser instrument assembly 40 can be increased, and the purpose of accurately calibrating the equipment beyond the original calibration range is achieved. Meanwhile, the extension rod 20 and the mounting plate 30 are detachably connected, and different size specifications of equipment can be disassembled for calibration, so that the work efficiency is effectively improved.

[0044] Specifically, in the embodiment of the present application, the extension rod mechanism 100 is used to extend the calibration range of the automobile calibration. In the automobile calibration equipment, left and right cross beams are arranged, and the AVM laser instrument assembly 40 is arranged on each cross beam to assist the automobile calibration. When the length of the automobile exceeds the total length of the cross beam, the AVM laser instrument assembly 40 is difficult to accurately calibrate, so the extension rod mechanism 100 is symmetrically arranged on the left and right cross beams of the automobile calibration equipment respectively, so as to further indirectly increase the length of the cross beam and expand the calibration range of the automobile calibration equipment.

[0045] In the embodiment of the present application, the AVM laser instrument assembly 40 is arranged on the mounting plate 30 of the extension rod mechanism 100, and the AVM laser instrument assembly 40 is used to assist the automobile calibration.

[0046] The extension rod 20 is made of light aluminum material, so as to reduce the stress burden on the cross beam due to the increase of the length of the end of the cross beam, and avoid the deformation of the cross beam. In other embodiments, the extension rod 20 can also be made of other light materials, as long as the cross beam is not deformed. Meanwhile, the extension rod 20 and the sliding plate 10 are detachably connected, and the specific connection includes the connection through the waist hook and / or the locking knob, so as to ensure the stability of the connection, thereby avoiding the falling of the extension rod 20 due to gravity and cantilever factors. One end of the extension rod 20 is the mounting portion 210, and the outer shape structure of the mounting portion 210 is a "knife" type. In other embodiments, the mounting portion 210 can also be arranged in other shapes such as rectangle, which is not limited.

[0047] Please refer to Figure 3 , Figure 3 is an exploded view of the extension rod mechanism in one embodiment of the present application. In some embodiments, the sliding plate 10 is provided with a first mounting slot 110, the extension rod 20 is provided with a first mounting hole 220 opposite the first mounting slot 110, the extension rod 20 is provided with a first connecting piece 230, and the first connecting piece 230 is sequentially arranged in the first mounting slot 110 and the first mounting hole 220.

[0048] Through the above structure, the first installation slot 110 is arranged opposite to the first installation hole 220, and the installation positions of the sliding plate 10 and the extension rod 20 can be relatively positioned. When the extension rod 20 needs to be used, the first connecting piece 230 can be inserted into the first installation slot 110 and the first installation hole 220 to realize the installation of the extension rod 20 on the sliding plate 10. When the extension rod 20 does not need to be used, the first connecting piece 230 is disassembled from the first installation slot 110 and the first installation hole 220, and then the separation of the extension rod 20 and the sliding plate 10 can be realized.

[0049] Specifically, in the embodiment of the present application, the first connecting piece 230 is in a cap-shaped structure as a whole, part of which is inserted into the first installation slot 110, and the remaining part covers the surface of the sliding plate 10 outside the first installation slot 110. Thus, the sliding plate 10 can be limited, and the sliding plate 10 is prevented from moving away from the extension rod 20 to separate the sliding plate 10 from the extension rod 20. The first connecting piece 230 is provided with a thread, and the first connecting piece 230 is also provided with a bolt 231. The bolt 231 is inserted into the first installation hole 220 of the extension rod 20 from the side opposite to the sliding plate 10 relative to the extension rod 20, and is connected to the first connecting piece 230 by a thread. Thus, the extension rod 20 is limited, and the extension rod 20 is prevented from moving away from the sliding plate 10 to separate the sliding plate 10 from the extension rod 20. In turn, the sliding plate 10 and the extension rod 20 are firmly connected.

[0050] In some embodiments, two first installation slots 110 are symmetrically arranged on the opposite sides of the sliding plate 10 respectively, and the extension rod 20 is provided with two first installation holes 220 opposite to the two first installation slots 110. The two first connecting pieces 230 are respectively inserted into the first installation slot 110 and the first installation hole 220.

[0051] Through the above structure, the two first installation slots 110 are respectively located on the opposite sides of the sliding plate 10, and the extension rod 20 is installed on the sliding plate 10 through the first installation slot 110. The connection strength of the sliding plate 10 and the extension rod 20 can be improved, so as to reduce the risk of falling of the extension rod 20 due to gravity and cantilever factors.

[0052] Specifically, in the embodiment of the present application, the two first installation slots 110 are symmetrically arranged relative to the central axis of the sliding plate 10, and the extension rod 20 is provided with two first installation holes 220 corresponding to the first installation slots 110. The same first connecting piece 230 is installed in the two groups of first installation slots 110 and first installation holes 220, and jointly bears the stress generated by the extension rod 20. In other embodiments, the number of first installation slots 110 can be set to be multiple, and the multiple first installation slots 110 are used to connect the sliding plate 10 and the extension rod 20.

[0053] In some embodiments, the first mounting slot 110 is a waist-shaped open slot, the opening direction of the open slot is vertically upward, and the first connecting piece 230 is a waist-shaped hook that is shaped to match the first mounting slot 110.

[0054] Through the above structure, the waist-shaped open slot can increase the structural strength of the connection between the first connecting piece 230 and the first mounting slot 110, effectively disperse stress, and improve the durability and stability of the structure. The first connecting piece 230 can be installed from the opening of the waist-shaped open slot.

[0055] Specifically, in the embodiments of the present application, the first mounting slot 110 is a waist-shaped slot, and the first connecting piece 230 is a waist-shaped hook. This structure can improve the stability of the connection and prevent the extension rod 20 from falling by relying only on the waist-shaped hook. In other embodiments, the structure of the first mounting slot 110 is not limited to a waist-shaped slot, but can also be other similar structures, such as a rectangular shape, etc.

[0056] In some embodiments, the sliding plate 10 is provided with a first connecting hole 120, the extension rod 20 is provided with a second connecting hole 240 opposite to the first connecting hole 120, the first connecting hole 120 and the second connecting hole 240 are provided with the same internal thread, the extension rod 20 is provided with a second connecting piece 250, the second connecting piece 250 is provided with an external thread that matches the internal thread, the second connecting piece 250 is sequentially arranged in the first connecting hole 120 and the second connecting hole 240, and the second connecting piece 250 threadedly connects the sliding plate 10 and the extension rod 20.

[0057] Through the above structure, the second connecting piece 250 threadedly connects the sliding plate 10 and the extension rod 20. As the depth of the second connecting piece 250 increases, the connection between the sliding plate 10 and the extension rod 20 is also more secure. By adjusting the depth of the second connecting piece 250, the connection stability of the sliding plate 10 and the extension rod 20 can be further improved, and the risk of loosening of the sliding plate 10 and the extension rod 20 can be avoided.

[0058] Specifically, in the embodiments of the present application, the second connecting piece 250 is a locking knob, and the first connecting hole 120 is a threaded hole. The locking knob can adjust the connection strength between the extension rod 20 and the sliding plate 10 by adjusting the depth of the threaded hole, and further reduce the risk of the extension rod 20 falling from the sliding plate 10. When the locking knob is completely tightened, the installation of the extension rod 20 on the sliding plate 10 is completed.

[0059] In some embodiments, the mounting portion 210 is provided with a magnet 211, and the mounting plate 30 is a magnetic member that is magnetically attracted to the magnet 211.

[0060] Through the above structure, the mounting plate 30 can be simply adsorbed on the mounting portion 210 of the extension rod 20 by the magnet 211, and the flexibility of mounting and dismounting the mounting plate 30 is improved while achieving the connection of the mounting plate 30 and the mounting portion 210, realizing quick and efficient dismounting, and effectively improving the production operation efficiency.

[0061] Specifically, in the embodiment of the present application, the other end of the extension rod 20 is provided with a mounting portion 210, and the mounting portion 210 magnetically adsorbs the magnetic mounting plate 30 by the magnet 211 to achieve connection. In some other embodiments, the mounting plate 30 can also be made of non-magnetic material, and a magnetic part is also provided on the mounting plate 30, which can also play a role in magnetic adsorption, for example, an iron sheet is provided on the mounting plate 30.

[0062] In some embodiments, the magnet 211 includes a plurality of magnets 211, which are uniformly distributed on the mounting portion 210.

[0063] Through the above structure, the plurality of magnets 211 are uniformly distributed on the mounting portion 210, which can collectively magnetically adsorb the mounting plate 30, evenly share the stress of each position of the mounting plate 30, further improve the connection stability of the mounting plate 30 and the extension rod 20, and will not affect the flexibility of dismounting the mounting plate 30.

[0064] Specifically, in the embodiment of the present application, the number of magnets 211 is four, and the four magnets 211 are arranged in a ring shape on the mounting portion 210 to improve the magnetic adsorption strength of the mounting portion 210 and the mounting plate 30. In some other embodiments, the number of magnets 211 is not limited to four, and can be adjusted according to actual needs. The arrangement of the magnets 211 is not limited to a ring shape, but can also be a linear arrangement.

[0065] In some embodiments, the mounting portion 210 is provided with a first positioning hole 212, the mounting plate 30 is provided with a second positioning hole 310 opposite to the first positioning hole 212, the mounting portion 210 is provided with a positioning pin 213, and the positioning pin 213 is sequentially arranged in the first positioning hole 212 and the second positioning hole 310.

[0066] Through the above structure, the cooperation of the positioning pin 213 and the first positioning hole 212 and the second positioning hole 310 realizes the positioning of the mounting plate 30, so that the mounting plate 30 can be mounted on the fixed position of the mounting portion 210, thereby not only improving the connection strength between the mounting plate 30 and the mounting portion 210, but also ensuring the accurate positioning of the AVM laser instrument assembly 40 through the accurate positioning of the mounting plate 30, thereby improving the accuracy of calibration.

[0067] Specifically, in the embodiment of the present application, the first positioning holes 212 include two, and the two first positioning holes 212 are respectively arranged on the left and right sides of the mounting portion 210. The second positioning holes 310 also include two, and the two second positioning holes 310 are also arranged on the left and right sides of the mounting plate 30. The distance between the two first positioning holes 212 is equal to the distance between the two second positioning holes 310, so that the positions of the first positioning holes 212 and the second positioning holes 310 correspond to each other.

[0068] In some embodiments, the side of the mounting plate 30 away from the extension rod 20 is provided with a connecting plate 320, the connecting plate 320 is provided with a third connecting hole 321, and the connecting plate 320 is provided with a third connecting piece 322, which is inserted into the third connecting hole 321 and the AVM laser instrument assembly 40.

[0069] Through the above structure, the connecting plate 320 is connected to the AVM laser instrument assembly 40, and the connecting plate 320 is installed on the mounting plate 30 through the third connecting hole 321 and the third connecting piece 322. Therefore, the position of the AVM laser instrument assembly 40 relative to the mounting plate 30 can be controlled, and the precise positioning of the AVM laser instrument assembly 40 is further realized, thereby improving the accuracy of the calibration.

[0070] Specifically, in the embodiment of the present application, a plurality of third connecting holes 321 are formed on the connecting plate 320, and the third connecting piece 322 is a connecting piece such as a bolt or a pin. The third connecting piece 322 is inserted into the third connecting hole 321 from the side of the connecting plate 320 away from the AVM laser instrument assembly 40, so as to install the AVM laser instrument assembly 40 on the connecting plate 320.

[0071] In some embodiments, the mounting portion 210 is provided with a safety rope 214, and the mounting plate 30 is provided with a safety ring 330. An end of the safety rope 214 away from the mounting portion 210 is configured to be detachably buckled on the safety ring 330.

[0072] Through the above structure, the buckling of the safety rope 214 and the safety ring 330 is equivalent to connecting the mounting plate 30 to the mounting portion 210 again. In general, the safety rope 214 is in a relaxed state and does not limit the movement of the mounting plate 30. However, in special cases, for example, when the mounting plate 30 is separated and falls off from the extension rod 20 due to external impact, the safety rope 214 is tightened and prevents the mounting plate 30 from further falling, thereby protecting the safety of the AVM laser instrument assembly 40.

[0073] Specifically, in the embodiment of the present application, the fixed end of the safety rope 214 is installed on the mounting portion 210 of the extension rod 20, and the movable end of the safety rope 214 is provided with an openable buckle. The movable end of the safety rope 214 is connected to the safety ring 330 through the buckle.
