[0025] 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 of 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.
[0026] Specific examples are given below.
[0027] like Figure 1 , 2As shown in , 3 and 6, a portable bracket for a laser rangefinder comprises a column 1; a first slide groove 11 is provided on the inner wall of the column 1; a card slot 12 is provided in the middle of the first slide groove 11; a slide 13 is slidably connected to the inner wall of the first slide groove 11; a card pin 14 is fixedly connected to the top wall of the card slot 12; a card hole 15 matching the shape of the card pin 14 is provided in the middle of the slide 13; a fixing member 16 is fixedly connected to the bottom of the slide 13; a plurality of groups of legs 17 are rotatably connected to the middle of the fixing member 16; when working, the staff needs to install the rangefinder on the top of the column 1, and then expand the plurality of groups of legs 17 outward and install and fix them on the ground. By providing the first slide groove 11 on the inner wall of the column 1, when the legs 17 are in use, the protruding position of the slide 13 will be stuck at the inner wall of the card slot 12 under the action of gravity, and cooperate with the card pin 14 and the card pin 14 to limit its position, and the slide 13 needs to be retracted as a whole When storing the column 1, the staff can first pull the column 1 upward to make the raised position of the slide 13 contact the specified inner wall of the first slide groove 11, and then rotate the top of the column 1, and the slide 13 will slide along the inner wall of the first slide groove 11 until the slide 13 slides and approaches the top position of the column 1, and then rotate the column 1 again, so that the slide 13 can be at the specified position inside the column 1, and then the multiple groups of legs 17 are stored. This step cooperates with the slide 13 that slides inside the column 1 to store its overall position, reducing the phenomenon that when storing it, usually multiple legs 17 are bent and stored in sequence, so that the overall length of the column 1 is shortened and a certain space is occupied, reducing certain inconveniences during carrying or transportation, and after the raised latch 14 is stuck in the latch hole 15, the phenomenon of shaking and position displacement of the column 1 during use can be reduced.
[0028] like Figure 1 , 2As shown in Figure 5, two groups of storage boxes 2 are fixedly connected to the outer wall of the column 1; a second slide groove 21 is opened in the middle of the storage box 2; two groups of limit rods 22 are fixedly connected to the middle of the column 1; a movable part 23 is slidably connected to the middle of the limit rod 22, and the movable part 23 is slidably connected inside the second slide groove 21; the end of the movable part 23 is fixedly connected to a vertical plate 24, and the vertical plate 24 is arranged inside the storage box 2; during work, by arranging two groups of storage boxes 2 on the outer wall of the column 1, and then when the multiple groups of legs 17 are unfolded and used, the staff can place an appropriate amount of heavy objects from the outside inside the storage box 2, and contact the vertical plate 24 inside the storage box 2. Under the action of the falling of the heavy objects, the multiple groups of legs 17 can be inserted into the installation The movable part 23 sliding in the middle of the two sets of limit rods 22 can improve the stability of the staff when taking out the heavy objects in the subsequent process, and reduce the problem of the storage box 2 having a narrow aperture and a troublesome taking-out process.
[0029] like Figure 2 and 4 As shown, the bottom of the fixing member 16 is threadedly connected with a screw rod 3; the bottom of the screw 3 is fixedly connected with a clamp 31; the end of the clamp 31 is fixedly connected with a buckle 32; during operation, by arranging the screw rod 3 at the bottom of the fixing member 16, the staff can use a tool to rotate the bottom of the clamp 31 after closing the multiple groups of legs 17 and the fixing member 16, so that the clamp 31 rotates after being subjected to force, and the buckle 32 of the soft material will contact the middle part of the leg 17, and the multiple groups of legs 17 are stored and fixed. This step cooperates with the multiple groups of buckles 32 to support the stored legs 17, reduce the problem of inertial expansion of the legs 17 during storage and transportation, and reduce the problem of direct expansion of the legs 17 and collision with the inner wall of the column 1, thereby causing obvious wear.
[0030] like Figure 5As shown, a spring 4 is fixedly connected to the top of the vertical plate 24; a guide plate 41 is fixedly connected to the top of the spring 4, and the middle part of the guide plate 41 is inclined; during operation, by providing an inclined guide plate 41 on the top of the vertical plate 24, when the staff places a heavy object inside the storage box 2, the edge of the heavy object will first contact the top of the guide plate 41, and after contacting the guide plate 41, it will squeeze the middle part of the spring 4, and the shaking force generated at the same time will transfer the heavy object to the middle position of the vertical plate 24. This step cooperates with the guide plate 41 to place the heavy object in the center, reducing the problem of the stacking position of the heavy object being offset from the edge of the storage box 2, which causes the center of gravity of the column 1 as a whole to be unstable when in use.
[0031] like Figure 1 , 2 As shown in 6, an observation window 5 is fixedly connected to the middle of the column 1; during operation, by providing the observation window 5 in the middle of the column 1, the staff can observe the inside of the column 1 through the observation window 5 during the sliding process of the slide 13, so as to determine the sliding position of the slide 13. This step, combined with the provision of the observation window 5, can improve the staff's accuracy in sliding the slide 13 and reduce the phenomenon of misalignment of the fixed position of the slide 13.
[0032] like Figure 5 As shown, the middle part of the movable part 23 is rotatably connected to the rotating drum 6, and the middle part of the rotating drum 6 is recessed. When working, by providing the rotating drum 6 in the middle part of the movable part 23, the staff can move their hands close to the position of the rotating drum 6 and deeply contact the recessed position of the rotating drum 6 before pulling the overall position of the movable part 23. This step utilizes the rotating drum 6 to improve the stability when pulling the movable part 23, and at the same time, cooperates with the recessed rotating drum 6 to improve the friction between the two when they are in contact.
[0033] like Figure 4 As shown, a rubber pad 7 is fixedly connected to the middle part of the buckle 32; when working, by arranging multiple groups of rubber pads 7 in the middle part of the buckle 32, when the buckle 32 is close to the outer wall of the leg 17, the rubber pad 7 of soft material will be squeezed and deformed, and the middle part of the leg 17 will be fixed. This step cooperates with the rubber pad 7 to fill the activity space after the leg 17 is stored, and further reduces the problem of shaking of the leg 17 during exercise or carrying.
[0034] Working principle: by installing the rangefinder on the top of the column 1, and then unfolding the multiple groups of legs 17 outward and fixing them on the ground, by setting the first slide groove 11 on the inner wall of the column 1, when the legs 17 are in use, the protruding position of the slide 13 will be stuck on the inner wall of the slot 12 under the action of gravity, and cooperate with the bayonet 14 and the bayonet 14 to limit its position. When the slide 13 needs to be stored in the column 1 as a whole, the staff can first pull the column 1 upward to make the protruding position of the slide 13 contact the specified inner wall of the first slide groove 11, and then the top of the column 1 can be rotated, and the slide 13 will slide along the inner wall of the first slide groove 11 until the slide 13 slides. And approach the top position of the column 1, then rotate the column 1 again, so that the sliding piece 13 can be at the designated position inside the column 1, and then the multiple sets of legs 17 complete the storage work, by providing two sets of storage boxes 2 on the outer wall of the column 1, and then when the multiple sets of legs 17 are unfolded and used, the staff can place an appropriate amount of heavy objects from the outside inside the storage box 2 and contact with the vertical plate 24 inside the storage box 2. Under the action of the falling of the heavy objects, the multiple sets of legs 17 can be inserted into the inside of the installed ground and their position is reinforced. At the same time, when the heavy objects in the storage box 2 need to be taken out, the staff can pull the middle part of the movable part 23 upwards, and the movable part 23 will slide in the middle of the limit rod 22 and synchronously belt The movable vertical plate 24 moves upward, thereby discharging the heavy objects accumulated on the top of the vertical plate 24 to the outside and taking them out. By providing a screw 3 at the bottom of the fixing piece 16, the staff can use a tool to rotate the bottom of the clamp 31 after closing the multiple groups of legs 17 and the fixing piece 16, so that the clamp 31 rotates after being subjected to force, and the buckle 32 of the soft material will contact the middle part of the leg 17, and the multiple groups of legs 17 will be stored and fixed. By providing an inclined guide plate 41 at the top of the vertical plate 24, when the staff places the heavy objects in the storage box 2, the edge of the heavy objects will first contact the top of the guide plate 41, and in the process of contacting the guide plate 41, the spring 4 will be squeezed. At the same time, the shaking force generated will transfer the weight to the middle position of the vertical plate 24. By providing an observation window 5 in the middle of the column 1, the staff can observe the inside of the column 1 through the observation window 5 during the sliding process of the slider 13, so as to determine the sliding position of the slider 13. By providing a rotating drum 6 in the middle of the movable part 23, the staff's hand will first approach the position of the rotating drum 6 and deeply contact the recessed position of the rotating drum 6 before pulling the overall position of the movable part 23. By providing multiple groups of rubber pads 7 in the middle of the buckle 32, when the buckle 32 is close to the outer wall of the leg 17, the rubber pad 7 of the soft material will be squeezed and deformed, and the middle part of the leg 17 will be fixed.
