The right side wall is provided with a rotating shaft 3 through a bearing, and a support frame 4 is installed on the outer wall of the rotating shaft 3. The support frame 4 under the action of external force can drive the rotating shaft 3 to rotate relative to the rear seat 2, so that the support frame 4 can be unfolded relative to the rear seat 2, and the support frame 4 can support the portable rangefinder body 1 and the rear seat 2 as a whole, so as to meet the demand of continuous tilt angle support. The support frame 4 rotates and fits the side wall of the rear seat 2. At this time, the support frame 4 is stored at the side wall of the rear seat 2. The width of the support frame 4 is set to 3cm-5cm. The side wall and the bottom end of the rear seat 2 shrink 5cm-8cm inward relative to the portable rangefinder body 1. Sufficient space can be provided for the storage of the support frame 4. The space enables the support frame 4 to be flush with the side wall of the rear seat 2 when in the storage state, ensuring the regularity of the overall external shape of the device. The support frame 4 is divided into a first state and a second state. The support frame 4 in the first state is rotated and stored at the side wall of the rear seat 2 to achieve the retraction of the support frame 4. The support frame 4 in the second state is unfolded to the rear side relative to the rear seat 2 to achieve the inclined support for the portable rangefinder main body 1 and the rear seat 2. The outer wall of the support frame 4 is provided with a receiving groove 5, and the inner cavity of the receiving groove 5 is rotated and overlapped with a folding canopy 6. The receiving groove 5 provides sufficient receiving space for the rotation and overlap of the folding canopy 6. The folding canopy 6 has the same principle as the French canopy on the market, and adopts a rotating and continuous The foldable shielding cloth and the supporting rod are arranged, which will not be described in detail here. Under the action of external force, the foldable shielding shed 6 can be unfolded to shade the screen of the portable rangefinder body 1, and the foldable shielding shed 6 can also be folded and stored until it is completely embedded in the inner cavity of the supporting frame 4 to ensure that the storage and unfolding of the foldable shielding shed 6 can be freely adjusted. The foldable shielding shed 6 is divided into an unfolded state and a stored state. The foldable shielding shed 6 in the unfolded state blocks the top of the portable rangefinder body 1 to block the screen of the portable rangefinder body 1 to prevent direct sunlight from shining on the screen and hindering reading. The foldable shielding shed 6 in the stored state rotates and overlaps with the inner cavity of the accommodating groove 5 to realize the storage of the foldable shielding shed 6.

[0028] See also Figure 2 and Figure 3As shown, a groove body 7 is provided at the side wall of the portable rangefinder body 1, and a limit plate 8 is provided in the inner cavity of the groove body 7 through a pin shaft, and the limit plate 8 is rotatably provided at the rear side of the outer wall of the rear seat 2. The shape of the limit plate 8 is set to be L-shaped, and a through groove 9 is provided at the free end of the limit plate 8. By limiting the through groove 9, the free end of the L-shaped limit plate 8 can be limited to achieve synchronous limiting of the support frame 4 and the folding canopy 6, and a positioning component for positioning the free end of the limit plate 8 is provided on the rear side of the outer wall of the rear seat 2, and the support frame 4 and the folding canopy 6 can be limited by the positioning component.

[0029] Specific reference Figure 3 As shown, the positioning assembly includes a limit rod 10 fixed and vertically installed on the rear side wall of the rear seat 2, a baffle 11 is installed on the outer wall of the limit rod 10, and a limit plate 12 and a spring 13 are sleeved on the outer wall of the limit rod 10. The two ends of the spring 13 are respectively connected to the baffle 11 and the limit plate 12, driving the limit plate 12 to move forward, leaving enough rotation space for the limit plate 8, and rotating the limit plate 8 until the through groove 9 is sleeved on the outer wall of the limit rod 10, removing the external force driving the limit plate 12, and at this time, the elastic force of the spring 13 is used to cause the limit plate 12 to fit tightly against the outer wall of the limit plate 8 to limit the position of the limit plate 8 at this time, and the position of the support frame 4 and the folding shelter 6 can be limited by the limit plate 8 after the limit is limited, so as to prevent the support frame 4 and the folding shelter 6 from automatically unfolding.

[0030] See also Figure 3 As shown, the limiting piece 12 is attached to the outer wall of the free end of the limiting plate 8, so that the free end of the limiting plate 8 can be limited by means of the limiting piece 12; the diameter of the limiting piece 12 is larger than the diameter of the through slot 9, so as to ensure that when the limiting piece 12 limits the limiting plate 8, the limiting piece 12 can always be located at the front side of the through slot 9, and the limiting piece 12 will not pass through the through slot 9 to the rear side, thereby ensuring that the limiting piece 12 plays its role accurately.

[0031] The working principle of a portable rangefinder in this embodiment is as follows:

[0032] When used in an outdoor environment, the limit plate 12 is driven to move forward, at which time the limit plate 12 compresses the spring 13 and rotates the limit plate 8 outward, causing the through slot 9 on the outer wall of the limit plate 8 to disengage from the outer wall of the limit rod 10. At this time, the support frame 4 and the foldable shielding shed 6 are disengaged from the limiting effect at the limit plate 8, and the external force drives the support frame 4 to rotate to the top of the rear seat 2, and causes the foldable shielding shed 6 to disengage from the inner cavity of the accommodating groove 5 and unfold to the front side. At this time, the foldable shielding shed 6 can shield the screen at the portable rangefinder body 1 to prevent sunlight from directly shining on the screen of the portable rangefinder body 1 and affecting subsequent readings;

[0033] After the equipment is used, the foldable shelter 6 is folded and stored into the inner cavity of the accommodating groove 5, and the supporting frame 4 is driven to rotate and reset to the bottom end of the rear seat 2. At this time, the supporting frame 4 is flush with the side wall of the rear seat 2 to ensure the regularity of the external shape of the equipment; the limiting piece 12 is driven to move forward to leave enough rotation space for the limiting plate 8, and the limiting plate 8 is rotated to the outer wall of the limiting rod 10 where the through groove 9 is sleeved, and the external force driving the limiting piece 12 is removed. At this time, the elastic force of the spring 13 is used to cause the limiting piece 12 to fit tightly against the outer wall of the limiting plate 8 to limit the position of the limiting plate 8 at this time. With the help of the limiting plate 8 after limiting, the position of the supporting frame 4 and the foldable shelter 6 can be limited to prevent the supporting frame 4 and the foldable shelter 6 from automatically unfolding;

[0034] When the device is used indoors in an environment where the shading function is not required, if continuous measurement of the tilt angle is required, the support frame 4 can be deployed rearwardly relative to the rear seat 2 to achieve tilt support of the rear seat 2 and the portable rangefinder body 1 by the support frame 4, thereby meeting the requirement that the support frame 4 always continuously measures a certain tilt angle;

[0035] The utility model can shield the screen of the portable rangefinder body 1 with the help of the unfolded folding shielding shed 6, so as to prevent the direct sunlight from shining on the screen of the portable rangefinder body 1 and causing reflection. The screen of the portable rangefinder body 1 after shielding will not be affected by the sunlight, so that the staff can read the readings on the screen of the portable rangefinder body 1 more conveniently and clearly, and the accuracy of the distance measurement result is guaranteed. In addition, the support frame 4 can be opened and supported to the rear side relative to the rear seat 2, so as to realize the support function of the portable rangefinder body 1, and the portable rangefinder body 1 can be kept at an angle for a long time for measurement without the help of other tools. The versatility of the equipment is stronger, and when the support frame 4 is in the storage state, it can be kept flush with the side wall of the rear seat 2, so as to ensure the regularity of the overall external shape of the equipment.

[0036] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
