Description

Technical Field

[0001] This utility model relates to the field of rangefinder bracket technology, specifically to a bracket foot and a rangefinder. Background Technology

[0002] A rangefinder bracket is a device used to fix or assist in the installation of a rangefinder. Its core function is to improve the stability and accuracy of the measurement process through physical support. As an important component of the rangefinder bracket, the feet mainly achieve stability and adaptability through their physical characteristics.

[0003] In existing technologies, when fixing support feet, in order to enhance stability, the support feet need to be inserted into the soil. However, the length of the support feet is usually fixed, and the required insertion length is different for softer soil and more compact soil, resulting in low applicability of existing support feet. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the above-mentioned traditional technology and provide a bracket foot nail and rangefinder that overcomes or at least partially solves the above-mentioned technical problems.

[0005] The objective of this utility model is achieved through the following technical measures:

[0006] This utility model provides a bracket foot and a rangefinder, including a bracket body and a foot body. The bracket body is hollow, and the foot body is slidably fitted into the hollow part of the bracket body. The bracket body is provided with a foot telescopic device for extending and retracting the foot body within the bracket body.

[0007] In a preferred embodiment, the foot spike telescopic device includes a plurality of through holes, which are formed through the support body and are arranged linearly along the axial direction.

[0008] In a preferred embodiment, a pin is provided between the through hole and the foot nail body, the pin being sleeved through the through hole and inside the foot nail body.

[0009] In a preferred embodiment, the end of the pin is fitted with a retaining sleeve made of an elastic material, the diameter of which is larger than the diameter of the through hole.

[0010] In a preferred embodiment, the foot spike telescopic device includes a threaded rod fixedly installed on the top of the foot spike body, and a drive block is rotatably sleeved inside the bracket body, with the threaded rod threadedly sleeved inside the drive block.

[0011] In a preferred embodiment, a limiting head is fixedly installed at the top of the threaded rod, and the length of the threaded rod is less than the length of the foot nail body.

[0012] A rangefinder, characterized in that it includes a bracket foot as described in any one of the above claims.

[0013] The present invention provides a bracket foot spike and a rangefinder, the advantages of which include:

[0014] By incorporating a telescopic foot spike mechanism, users can move the foot spike body downwards through the hollow section of the support body, causing the foot spike body to detach from the interior of the support body. This allows users to determine the insertion depth of the foot spike based on the softness of the soil. Attached Figure Description

[0020] Example: Refer to Figures 1-4 This utility model provides a technical solution: a support foot nail and a rangefinder, including a support body 1 and a foot nail body 2. The end of the foot nail body 2 is conical. The support body 1 is hollow. The foot nail body 2 is slidably fitted into the hollow part of the support body 1. The cross-sections of both the foot nail body 2 and the support body 1 are rectangular, so that the foot nail body 2 can only slide vertically on the support body 1. The support body 1 is provided with a foot nail telescopic device for extending and retracting the foot nail body 2 within the support body 1. The foot nail telescopic device includes several through holes 31, which are opened through the support body 1 and are linearly arranged along the axial direction. By setting the foot nail telescopic device, the user can move the foot nail body 2 downward in the hollow part of the support body 1, so that part of the foot nail body 2 is disengaged from the interior of the support body 1, thereby determining the insertion depth of the foot nail according to the softness of the soil.

[0021] First embodiment:

[0022] Reference Figures 1 to 2 A pin 4 is provided between the through hole 31 and the foot nail body 2. The foot nail body 2 is adapted to have a through hole. The pin 4 is sleeved through the through hole 31 and the through hole on the foot nail body 2. In the initial state, the pin 4 passes through the through hole and the uppermost through hole 31, so that the foot nail body 2 and the bracket body 1 overlap as much as possible, reducing the space occupied. By setting the through hole 31, when the user fixes the bracket, the pin can be disengaged from the inside of the through hole 31. At this time, the user can move the foot nail body 2 downward in the hollow part of the bracket body 1, so that part of the foot nail body 2 is disengaged from the inside of the bracket body 1 until the foot nail body 2 extends a preset distance, and then insert the pin into the through hole and the corresponding through hole 31.

[0023] Reference Figures 1 to 2 The end of the pin 4 is fitted with a retaining sleeve 5, which is made of elastic material. The diameter of the retaining sleeve 5 is larger than the diameter of the through hole 31. By setting the retaining sleeve 5, after the user inserts the pin into the corresponding through hole 31, the retaining sleeve 5 is locked at the end of the pin. Since the diameter of the retaining sleeve 5 is larger than the diameter of the through hole 31, the pin is limited and cannot be detached from the inside of the through hole 31, thus avoiding the problem of the pin accidentally falling off during transportation and use.

[0024] Second embodiment:

[0025] Reference Figures 3 to 4 The foot spike telescopic device includes a threaded rod 32, which is fixedly installed on the top of the foot spike body 2. A drive block 6 is rotatably sleeved inside the bracket body 1. The threaded rod 32 is threaded inside the drive block 6. The outer surface of the foot spike body 2 is in contact with the inner wall of the bracket body 1. By setting the threaded rod 32, when the user fixes the bracket, he rotates the drive block 6. Through the threaded connection between the drive block 6 and the threaded rod 32, and the sliding connection between the foot spike body 2 and the bracket body 1, the foot spike body 2 moves downward until it reaches the preset position and then stops rotating the threaded rod 32. The threaded rod 32 is positioned by the friction between the drive block 6 and the threaded rod 32.

[0026] Furthermore, a fastening nut can be installed above the drive block 6. The fastening nut is sleeved on the surface of the threaded rod 32 and threadedly connected to the threaded rod 32. When the threaded rod 32 drives the foot nail body 2 to move to the preset position, the fastening nut is tightened until the fastening nut and the top of the drive block 6 come into contact. The positioning effect of the threaded rod 32 is improved by the friction between the fastening nut and the drive block 6.

[0027] Reference Figures 3 to 4A limiting head 7 is fixedly installed on the top of the threaded rod 32. The length of the threaded rod 32 is less than the length of the foot nail body 2. By setting the limiting head 7, the movement distance of the bolt rod is limited, so as to prevent the threaded rod 32 from separating from the drive block 6. In order to avoid the problem that the threaded rod 32 will rotate with the drive block 6 after the foot nail body 2 completely separates from the bracket body 1 and loses the limiting cooperation between the foot nail body 2 and the bracket body 1, the length of the threaded rod 32 is less than the length of the foot nail body 2.

[0028] A rangefinder, characterized in that it comprises a support foot pin containing any one of the above-mentioned features.

[0029] Specifically, the working process or working principle of the bracket foot spike and rangefinder is as follows: When in use, the rangefinder is transported to the designated surveying location, the three bracket bodies 1 are changed from a vertical state to an inclined state and arranged in a circular array, and the foot spike body 2 is extended from the inside of the bracket body 1 to the outside through the foot spike telescopic device until the length of the foot spike body 2 reaches the preset value, and the foot spike body 2 is fixed in the preset position.
