DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 6 As shown:

[0024] Embodiment 1: The utility model provides a rangefinder for engineering cost, comprising: a rangefinder mechanism 1, including a limit assembly 11, a rangefinder assembly 12 slidably embedded in the limit assembly 11, a group of locking assemblies 13 installed on the limit assembly 11, and a driving assembly 14 for driving the limit assembly 11 to rotate, wherein the locking assembly 13 can fix the rangefinder assembly 12 on the limit assembly 11; a tripod assembly 2 for supporting the limit assembly 11, and the driving assembly 14 is fixedly installed on the tripod assembly 2.

[0025] Specifically, the limiting assembly 11 includes a mounting platform 111, on which a T-shaped slot 112 is provided, and the bottom of the mounting platform 111 is annularly fixedly connected to a plurality of support rods 113, the bottoms of the plurality of support rods 113 are rotatably connected to guide wheels 114, and the guide wheels 114 are rotatably embedded in the tripod assembly 2, and one end of a rotating shaft 115 is also fixedly connected to the middle position of the bottom of the mounting platform 111, and the other end of the rotating shaft 115 is fixedly connected to the tripod assembly 2 through a bearing, and the outside of the rotating shaft 115 is fixedly connected to a driven gear 116, and the mounting platform 111 is also provided with a group of force storage grooves 117 connected to the T-shaped slot 112, one end of a second spring 118 is fixedly connected to the group of force storage grooves 117, and the other end of the second spring 118 is fixedly connected to a push block 119, and the mounting platform 111 is also symmetrically provided with storage grooves connected to the T-shaped slot 112.

[0026] Specifically, the rangefinder assembly 12 includes a rangefinder body 121, the bottom of which is fixedly connected to a T-shaped guide block 122 that matches the T-shaped slot 112. The rangefinder body 121 can be slidably embedded in the mounting platform 111 through the T-shaped guide block 122, and a group of locking holes 123 are opened on the T-shaped guide block 122.

[0027] Specifically, the locking assembly 13 includes a locking rod 131 that is limitedly slidably embedded in the storage groove, one end of the locking rod 131 is an inclined surface and can be embedded in the locking hole 123, the other end of the locking rod 131 extends to the outside of the mounting platform 111 and is fixedly connected to a handle 132, the outside of the locking rod 131 is fixedly connected to a limiting ring 133 at one end close to the inclined surface of the locking rod 131, and the outside of the locking rod 131 is provided with a first spring 134.

[0028] As can be seen from the above, when in use, the tripod assembly 2 is unfolded and fixed in a specified position, and then the T-shaped guide block 122 is aligned with the T-shaped slot 112 and the rangefinder body 121 is pushed. The rangefinder body 121 drives the T-shaped guide block 122 to slide along the T-shaped slot 112. During the sliding process of the T-shaped guide block 122, the inclined surface of the locking rod 131 is squeezed so that one end of the inclined surface of the locking rod 131 is squeezed into the storage slot. At this time, the first spring 134 is squeezed by the limiting ring 133 to be in a compressed state. When the locking hole 123 coincides with the storage slot, the first spring 134 restores its deformation and pushes the limiting ring 133 so that the locking rod 131 is inserted into the locking hole 123. At the same time, the T-shaped guide block 122 squeezes the push block 119, and the push block 119 pushes the second spring 118 to be in a compressed state to store force. At this time, the rangefinder body 121 is stably fixed on the mounting table 111 to avoid loosening or shaking during the measurement process. When the rangefinder body 121 needs to be removed, the handle 132 is pulled, and the handle 132 drives the locking rod 131 to disengage from the locking hole 123, and releases the limit on the T-shaped guide block 122. At this time, the second spring 118 recovers from the previous compressed state and pushes the push block 119. The push block 119 pushes the T-shaped guide block 122 to move, so that the locking hole 123 and the storage groove no longer overlap, and then the handle 132 is released, and the rangefinder body 121 can be conveniently taken out.

[0029] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the driving assembly 14 includes a motor 141 fixedly connected to the tripod assembly 2, and the output end of the motor 141 is fixedly connected to a driving gear 142, and the driving gear 142 is meshed with the driven gear 116.

[0030] Specifically, the tripod assembly 2 includes a support platform 21, a guide groove 22 is provided on the top of the support platform 21, a rotating shaft 115 is fixedly connected to the support platform 21 through a bearing, a guide wheel 114 is rotatably embedded in the guide groove 22, a motor 141 is fixedly connected to the top of the support platform 21, a plurality of outer support frames 23 are rotatably connected at the bottom edge of the support platform 21, an inner support frame 24 is slidably connected to the plurality of outer support frames 23, the outer support frames 23 and the inner support frames 24 can be fixed by bolts, a guide rod 25 is also fixedly connected to the middle position of the bottom of the support platform 21, a guide ring 26 is slidably connected to the outside of the guide rod 25, one end of a connecting rod 27 is rotatably connected to the outside of the guide ring 26, and the other end of the connecting rod 27 is rotatably connected to the outer support frame 23.

[0031] As can be seen from the above, the height of the adjustable device can be achieved by pulling the inner support frame 24 and then fixing the outer support frame 23 and the inner support frame 24 with bolts. By controlling the motor 141, the output end of the motor 141 drives the driving gear 142 to rotate, the driving gear 142 drives the driven gear 116 to rotate, the driven gear 116 drives the mounting platform 111 on the rotating shaft 115 to rotate, the mounting platform 111 drives the support rod 113 to rotate, and the support rod 113 drives the guide wheel 114 to rotate in the guide groove 22, so that the mounting platform 111 and the rangefinder body 121 are more stable when rotating, thereby facilitating the adjustment of the angle of the rangefinder body 121.
