Description

Technical Field

[0001] This utility model relates to the field of surveying equipment technology, specifically a tripod for a surveying instrument. Background Technology

[0002] Construction cost refers to the price of a project. The pricing process involves measurement, estimation, and budgeting. When completing the construction cost estimate, professional engineers need to use surveying instruments or conduct site surveys to measure the entire terrain in order to more accurately assess the construction cost.

[0003] Surveying instruments typically consist of a main body and a tripod, with the main body mounted on the tripod. Existing surveying instrument tripods usually include a platform with several support legs hinged to it. In use, the support legs are first fully extended and placed on the survey point. Then, the main body is bolted to the top of the platform. Next, the tripod is moved, and the length of the support legs is adjusted until the main body is aligned with the survey point and level, allowing for on-site surveying. This operation is convenient. However, to make the support leg length adjustable, existing support legs are usually telescopic and lack effective restraint. Therefore, during transport, the support legs can easily extend suddenly, affecting the storage and handling of the tripod. Utility Model Content

[0004] The purpose of this utility model is to provide a tripod for a surveying instrument in order to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a tripod for a surveying instrument, comprising a platform, wherein a plurality of supporting legs are hinged on the platform, each supporting leg comprising a housing and a supporting bar slidably connected inside the housing, the housing having a plurality of through slots, each through slot having a locking mechanism, the locking mechanism comprising a clamp for clamping the supporting bar, the clamp having a switch assembly for opening or closing the clamp.

[0006] As a further feature of this utility model, the clamp includes a first clamp plate and a second clamp plate. The first clamp plate is provided with a first connecting piece, and the second clamp plate is provided with a second connecting piece. A locking rod is connected to the first connecting piece, and a slot for the locking rod to be engaged is provided on the second connecting piece. A locking member is provided on the locking rod, and the locking member includes an arc-shaped segment with a groove. A connecting shaft is rotatably connected inside the groove. The end of the locking rod away from the first connecting piece passes through the connecting shaft and is connected to a limit block. An arc-shaped groove for the arc-shaped segment to be engaged is provided on the second connecting piece.

[0007] As a further feature of this invention, the locking member also includes a gripping section, the inner wall of which fits into the outer wall of the second hoop.

[0008] As a further feature of this invention, a connecting seat is provided on the housing, and a plurality of connecting blocks are provided on the platform and rotatably connected inside the connecting seat. A baffle for abutting against the connecting blocks is slidably connected inside the connecting seat.

[0009] As a further feature of this invention, the baffle is provided with several anti-slip protrusions.

[0010] As a further feature of this invention, each of the support bars is provided with a pad at the end away from the shell, and the pad is made of rubber material.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During transport, the support bar can be retracted into the housing first. Then, the clamp can be closed using the switch assembly. The closed clamp will tighten, clamping and fixing the part of the support bar inside the through groove, thus locking the support bar inside the housing. This effectively limits the support bar and prevents it from sliding out of the housing and elongating during transport, thus avoiding affecting the storage and transport of the tripod. When it is necessary to adjust the length of the support leg, the clamp can be unfolded using the switch assembly, thus releasing the clamp and unlocking the support bar. This allows the support bar to slide inside the housing, enabling the support leg to extend and retract freely, and thus freely adjust the length. The operation is convenient and simple.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 As shown, a tripod for a surveying instrument includes a platform 1 with several support legs hinged to it. Each support leg includes a housing 2 and support bars 3 slidably connected inside the housing 2. A pad 21, made of rubber, is provided at the end of each support bar 3 away from the housing 2, providing good elasticity and thus replacing the support bar 3 in contact with the bottom surface, resulting in better stability of the tripod. Several through slots 4 are provided on the housing 2, each containing a locking mechanism. The locking mechanism includes clamps for holding the support bars 3, and a switch assembly is provided on the clamps. The switch assembly is used to open or close the clamps, allowing the support bars 3 to be retracted before moving the tripod. Inside the housing 2, the clamp is closed by a switch assembly, which tightens the clamp to hold and fix the part of the support bar 3 located inside the through groove 4. This locks the support bar 3 inside the housing 2, effectively limiting its movement and preventing it from sliding out and elongating during transport, thus avoiding interference with the tripod's storage and handling. When the length of the support leg needs to be adjusted, the clamp can be opened by the switch assembly, releasing the clamp from the support bar 3 and allowing it to slide freely within the housing 2. This allows for free extension and retraction of the support leg, enabling easy and simple length adjustment.

[0020] Please see Figure 1 , Figure 2As shown, the clamp includes a first clamping plate 5 and a second clamping plate 6. A first connecting piece 7 is provided on the first clamping plate 5, and a second connecting piece 8 is provided on the second clamping plate 6. A locking rod 9 is connected to the first connecting piece 7, and a slot 10 for the locking rod 9 to engage is provided on the second connecting piece 8. A locking element is provided on the locking rod 9, which includes an arc-shaped segment 11 with a groove 12. A connecting shaft 13 is rotatably connected inside the groove 12. The locking rod 9 is located away from the first connecting piece 7. One end of the connecting shaft 13 passes through and is connected to the limiting block 14. An arc-shaped groove 15 for the arc-shaped segment 11 to engage is provided on the second connecting piece 8. When it is necessary to control the clamp's closure, the locking member can be flipped first, causing the arc-shaped segment 11 to engage with the arc-shaped groove 15 and abut against the inner wall of the groove 15. During this process, the rotation of the arc-shaped segment 11 will pull on the clamping rod 9, causing it to slide down. Since one end of the clamping rod 9 is restricted by the limiting block 14, when the clamping rod 9 slides to its limit position... The limiting block 14 firmly abuts against the rotating shaft, causing an interaction between the limiting block 14 and the rotating shaft, and between the arc-shaped segment 11 and the arc-shaped groove 15. This causes the arc-shaped segment 11 to firmly abut against the arc-shaped groove 15, bringing the first connecting piece 7 and the second connecting piece 8 closer together. Consequently, the first clamping piece 5 and the second clamping piece 6 close together, achieving clamping. When it is necessary to control the clamp to unfold, the locking member can be reversed, causing the arc-shaped segment 11 to flip accordingly, thereby releasing the contact between the arc-shaped segment 11 and the inner wall of the arc-shaped groove 15. This causes the locking rod 9 to slide upward, thereby moving the limiting block 14 away from the rotation axis, releasing the force on the first connecting piece 7 and the second connecting piece 8, and thus allowing the first hoop piece 5 and the second hoop piece 6 to unfold and unlock. The operation is relatively convenient and simple, saving time and effort. The locking component also includes a grip section 16, and the inner side wall of the grip section 16 fits with the outer side wall of the second hoop piece 6. By gripping the grip section 16 and applying force, the locking component can be rotated. The grip section 16 can be used as a force application point, making the operation relatively easy and effortless.

[0021] Please see Figure 3 , Figure 4 As shown, a connecting seat 17 is provided on the housing 2, and several connecting blocks 18 are rotatably connected to the inside of the connecting seat 17 on the platform 1. A baffle 19 is slidably connected inside the connecting seat 17 to abut against the connecting blocks 18. When moving the tripod, the support legs can be retracted, so that the connecting blocks 18 are retracted into the connecting seat 17. Then, the baffle 19 is pushed up until it abuts against the connecting blocks 18, thereby blocking the connecting blocks 18 and preventing them from rotating inside the connecting seat 17. This ensures the stability of the support legs when retracted and prevents them from opening during transportation, making the tripod easier to move. In addition, several anti-slip protrusions 20 are provided on the baffle 19, which greatly increases the friction coefficient of the baffle 19 surface, making it less likely to slip when pushing the baffle 19 and easier to apply force.
