Description

Technical Field

[0001] This application relates to the technical field of optical devices, and in particular to a dovetail plate. Background Technology

[0002] A telescope is a visual optical instrument used to observe distant objects; it is an indispensable tool in astronomical and terrestrial observation. Based on their operating principles, telescopes are generally classified into three types: radio telescopes, which collect electromagnetic waves to observe the electromagnetic radiation of distant objects; optical telescopes, commonly used in daily life; and astronomical telescopes, used in modern astronomy, which mainly include infrared telescopes, X-ray telescopes, and gamma-ray telescopes.

[0003] A telescope consists of a primary mirror and a stator, which are connected by a dovetail plate. When observing a telescope, a separate support is usually used to support the recording equipment for recording. Common recording equipment includes mobile phones, cameras, camcorders, and digital camera adapters.

[0004] Regarding the aforementioned technologies, the inventors believe that adding an extra support bracket to the recording equipment when using a telescope for observation increases the complexity and operational difficulty of the observation equipment, requiring more time and effort for setup and adjustment. Utility Model Content

[0005] To facilitate video recording of observed objects during telescope use, this application provides a dovetail plate.

[0006] The dovetail plate provided in this application adopts the following technical solution:

[0007] A dovetail plate includes a plate body, a support block protruding from one side of the plate body, and a threaded hole formed on the side of the support block opposite to the plate body along its own extension direction. The threaded hole is used for mounting a video recording device bracket.

[0008] Optionally, the outer wall of the support block is provided with rounded corners.

[0009] Optionally, a groove is formed on one surface of the plate.

[0010] Optionally, the plate body has an arc surface on one side facing away from the plate groove.

[0011] Optionally, the sidewall of the plate is provided with an inclined sliding surface.

[0012] Optionally, the groove wall of the plate is provided with a reinforcing block, and the reinforcing block has a connecting hole for bolts to pass through, and the bolts pass through the connecting hole to connect the plate to the outside of the telescope.

[0013] Optionally, the bottom of the slot is provided with a screw hole, through which a screw is used to connect the plate to the outside of the telescope.

[0014] Optionally, the support block is located at one end of the plate near the telescope lens.

[0015] Optionally, the support block is located at the end of the plate away from the telescope lens.

[0016] Optionally, the support block is disposed in the middle part of the plate.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] Threaded holes are made on the support block of the dovetail plate to connect the video recording equipment bracket, so that video can be recorded at any time when observing with the telescope without the need for an additional bracket to support the video recording equipment, thus simplifying the operation of the observation equipment.

[0019] The bracket can be directly mounted on the dovetail plate, allowing for easy adjustment of the recording device's angle and faster recording.

[0020] Creating a groove on one side of the dovetail board can reduce its weight and save materials. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] Example 1

[0027] This application discloses a dovetail plate. (Refer to...) Figure 1 and Figure 2The dovetail plate includes a plate body 1, with a support block 11 protruding from one side of the plate body 1. The support block 11 is located along the length of the plate body 1, away from the plate body 1, and close to the telescope lens. Specifically, the support block 11 can be integrally injection molded with the plate body 1, or hot-pressed with the plate body 1, or machined with the plate body 1 (using a cutting tool to remove excess material and leave the desired protruding shape), or welded to the plate body 1, etc. In the embodiment of this application, the support block 11 is integrally injection molded with the plate body 1.

[0028] The support block 11 has a threaded hole 111 on the side opposite to the plate 1 along its own extension direction. The threaded hole 111 is used for the video recording equipment bracket to be threadedly connected so that the video recording equipment can be installed on the dovetail plate.

[0029] Reference Figure 2 The outer wall of the support block 11 is provided with rounded corners 112. Both the side wall of the support block 11 away from the telescope lens and the side wall of the support block 11 near the telescope lens are provided with rounded corners 112. The purpose is to save materials and reduce the weight of the plate 1 itself.

[0030] Reference Figure 2 A groove 12 is formed on one surface of the plate body 1. A reinforcing block 15 is integrally injection molded on the groove wall of the groove 12. The reinforcing block 15 has a connecting hole 151 for bolts to pass through, and the bolts pass through the connecting hole 151 to connect the plate body 1 to the outside of the telescope. A screw hole 16 is formed at the bottom of the groove 12, and a screw passes through the screw hole 16 to connect the plate body 1 to the outside of the telescope.

[0031] Reference Figure 3 The plate 1 has an arc surface 13 on the side facing away from the slot 12. The arc surface allows the plate 1 to fit more closely to the outer wall of the telescope, making the connection between the telescope and the dovetail plate more secure.

[0032] Reference Figure 2 The side wall of plate 1 is provided with an inclined sliding surface 14. The inclined sliding surface 14 facilitates the sliding connection between the telescope support arm and the dovetail plate, reduces the friction caused by sliding, and increases the service life of the dovetail plate.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 is that the support block 11 is located on the length of the plate 1 and is located away from the plate 1 and far away from the telescope lens.

[0035] Example 3

[0036] The difference between this embodiment and Embodiment 1 is that the support block 11 is disposed in the length direction of the plate 1 and away from the middle part of the side wall of the plate 1.

[0037] The implementation principle (usage process, installation process) of a dovetail plate according to an embodiment of this application is as follows: When installing the dovetail plate, first align the plate 1 with the side with the arc surface 13 with the outer wall of the telescope, and then use bolts to thread the plate 1 through the connecting hole 151 to fix the plate 1 to the outer wall of the telescope; at the same time, use screws to connect the plate 1 to the outside of the telescope through the screw hole 16; when connecting the recording equipment, simply thread the bracket of the recording equipment to the threaded hole 111 opened on the support block 11.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
