Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, and in particular, to a portable hand-operated prism device for measurement. Background Technology

[0002] In fields such as engineering surveying and topographic mapping, accurate measurement of distances and angles is crucial for ensuring project quality and safety. Traditional surveying methods often rely on prisms in conjunction with instruments such as total stations. However, most existing prism devices are fixed structures and inconvenient to adjust. Fixed prism devices are difficult to move, cannot adapt to complex terrain conditions, and are not easily adjustable to suit different working conditions and scenarios. They suffer from problems such as inconvenience in movement, poor flexibility, and cumbersome operation, making it difficult to meet the needs of complex terrain and rapid measurement. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a portable hand-operated prism device for measurement.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A portable hand-operated prism device for measurement includes: a chassis with a vertically extending frame at the front and a handrail at the rear, the chassis having casters at its bottom; a sleeve rod fixedly mounted on the upper end of the frame, having a vertically extending circular hole; a movable frame with a circular rod inserted into the circular hole at its bottom, the circular rod being able to move up and down and rotate within the circular hole; a threaded post at the upper end of the movable frame; a prism mounting bracket with a first threaded hole adapted to the threaded post, threadedly connected to the threaded post, thereby enabling height adjustment through rotation relative to the movable frame; and a fixing member having a locked state for locking the circular rod and an unlocked state for disengaging from the circular rod; the fixing member is movably connected to the sleeve rod to switch between the locked and unlocked states.

[0006] Furthermore, the sleeve rod has a second threaded hole communicating with the circular hole on its peripheral wall, and the fixing member is a set screw threaded into the second threaded hole.

[0007] Furthermore, the fixing member also has a rotation adjustment state, in which the fixing member can limit the vertical position of the round rod while the round rod can rotate freely.

[0008] Furthermore, the outer peripheral wall of the round rod is provided with an annular groove for the end of the set screw to be inserted. The annular grooves are arranged vertically. In the locked state, the set screw is inserted into the corresponding annular groove and abuts against the inner wall of the annular groove; in the rotation adjustment state, the set screw is inserted into the corresponding annular groove and has a gap with the inner wall of the annular groove.

[0009] Furthermore, a screwing head is connected between the round rod and the threaded column, and the outer diameter of the screwing head is larger than that of the threaded column and the sleeve rod.

[0010] Furthermore, when the screw head abuts against the upper end of the sleeve, the uppermost annular groove aligns with the second threaded hole.

[0011] Furthermore, when the bottom wall of one of the annular grooves is flush with the upper end of the sleeve, the adjacent annular groove below is aligned with the second threaded hole.

[0012] Furthermore, the outer peripheral wall of the sleeve is provided with a cylindrical protrusion corresponding to the second threaded hole, and the second threaded hole extends to the end face of the cylindrical protrusion.

[0013] Furthermore, the vehicle chassis is provided with an inclined sleeve, and the handrail is provided with a plug rod, which is inserted into the sleeve and fixed.

[0014] Furthermore, a preload nut is threaded onto the threaded post, and the preload nut is used to abut against the prism mounting bracket.

[0015] This utility model has the following beneficial effects:

[0016] The chassis and casters facilitate the movement of the entire device, especially in complex terrain conditions, allowing for easy relocation to the desired location and adaptability to various measurement environments. A rear handrail provides a convenient operating position for the operator. The round rod of the movable frame inserts into the round hole of the sleeve rod, allowing for free height, elevation, and rotation within the hole, providing flexible adjustment of height and angle. This enables the prism to quickly adapt to different measurement needs, especially in complex terrain and variable working conditions, allowing for rapid adjustment to the optimal position. The prism mounting bracket connects to the movable frame via a threaded post, enabling quick installation and height adjustment. This simplifies the operation process, improves measurement efficiency, and reduces on-site adjustment time. The locking and unlocking function of the fixing component allows for quick fixing or release of the round rod's position, further enhancing operational convenience. The fixing component is movably connected to the sleeve rod, allowing for easy switching between locked and unlocked states, ensuring stability and flexibility during the measurement process.

[0036] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a portable hand-pushed prism device for measurement, comprising a chassis 100, a sleeve 200, a movable frame 300, a prism mounting bracket 400, and a fixing component.

[0037] The chassis 100 has a vertically extending frame 110 at the front and a handrail 120 at the rear. Rollers 140 are installed at the bottom of the chassis 100. Specifically, the chassis 100 includes a crossbar 150 and a longitudinal bar 160. The longitudinal bar 160 is vertically fixed to the middle of the crossbar 150. Rollers 140 are installed on both sides of the bottom of the crossbar 150 and on the side of the longitudinal bar 160 away from the bottom of the crossbar 150. The rollers 140 can be swivel casters or swivel casters with brakes. The vertical frame 110 is located on the longitudinal bar 160, and the handrail 120 is connected to the middle of the crossbar 150.

[0038] The sleeve rod 200 is fixedly installed on the upper end of the vertical frame 110. The sleeve rod 200 has a vertically extending circular hole 210. The connection between the sleeve rod 200, the vertical frame 110 and the chassis 100 can all be fixed by welding. Vertical means the height direction.

[0039] The bottom of the movable frame 300 is provided with a round rod 310 that can be inserted into a round hole 210. The round rod 310 can move up and down and rotate within the round hole 210. The upper end of the movable frame 300 is provided with a threaded post 320.

[0040] The prism mounting bracket 400 has a first threaded hole 410 that mates with the threaded post 320, and is threadedly connected to the threaded post 320, thereby enabling height adjustment through rotation relative to the movable bracket 300, thus achieving multiple composite adjustments. For example... Figure 3As shown, a prism 600 is rotatably mounted on the prism mounting bracket 400, thereby adjusting the height and angle of the prism 600 by adjusting the height and angle of the prism mounting bracket 400.

[0041] The fastener has a locked state where it locks the position of the round rod 310 and an unlocked state where it is no longer in contact with the round rod 310; the fastener is movably connected to the sleeve rod 200 to achieve switching between the locked and unlocked states.

[0042] This utility model provides a portable hand-push prism device for measurement. The chassis 100 and casters 140 facilitate the movement of the entire device, especially in complex terrain conditions, allowing it to be easily moved to the required position and adapt to various measurement environments. The rear handle 120 provides a convenient operating position for the operator. The round rod 310 of the movable frame 300 inserts into the round hole 210 of the sleeve rod 200, allowing free height and rotation within the round hole 210, providing flexible height and angle adjustment. This enables the prism to quickly adapt to different measurement needs, especially in complex terrain and changing working conditions, allowing for rapid adjustment to the optimal position. The prism mounting bracket 400 is connected to the movable frame 300 via a threaded post 320, enabling quick installation and height adjustment through the threaded connection. This simplifies the operation process, improves measurement efficiency, and reduces on-site adjustment time. The locking and unlocking function of the fixing components allows the position of the round rod 310 to be quickly fixed or released, further improving operational convenience. The fixing element is movably connected to the sleeve 200, allowing for easy switching between locked and unlocked states, ensuring stability and flexibility during measurement. The entire device can be quickly deployed and adjusted, improving measurement efficiency. The locking function of the fixing element further enhances the stability of the device, ensuring that it will not shift position due to external forces during measurement, thereby guaranteeing the accuracy of the measurement results.

[0043] Reference Figure 3 In some embodiments of this utility model, the sleeve rod 200 has a second threaded hole 220 communicating with the circular hole 210 on its peripheral wall. The fixing member is a set screw 500 threadedly connected to the second threaded hole 220, and the set screw 500 is helically and movably installed on the sleeve rod 200. In the locked state, the set screw 500 abuts against the peripheral wall of the circular rod 310 to lock the position of the circular rod 310; in the unlocked state, the set screw 500 separates from the circular rod 310 to disengage, thereby allowing the circular rod 310 to rotate and move freely. The state switching can be achieved simply by turning the set screw 500, without having to completely unscrew the set screw 500, making the operation simple and convenient.

[0044] Reference Figure 6As shown, in a further embodiment of this utility model, the fixing member also has a rotation adjustment state. In the rotation adjustment state, the fixing member (set screw 500) can limit the vertical position of the round rod 310 while the round rod 310 can rotate freely. That is, in the rotation adjustment state, the fixing member (set screw 500) only limits the vertical position of the round rod 310, and the round rod 310 can still rotate to adjust its position. In this way, the vertical position of the round rod 310 is avoided when only the round rod 310 needs to be rotated for adjustment.

[0045] In a further embodiment of this utility model, the outer peripheral wall of the round rod 310 is provided with an annular groove 311 for the end of the set screw 500 to be inserted. The annular grooves 311 are arranged vertically, such as... Figure 4 As shown, the locked set screw 500 is embedded in the corresponding annular groove 311 and abuts against the inner wall of the annular groove 311; as Figure 6 As shown, in the rotation adjustment state, the set screw 500 is embedded in the corresponding annular groove 311 and has a gap with the inner wall of the annular groove 311. That is, the set screw 500 is embedded in the annular groove 311 and has a gap with the cylindrical inner wall of the annular groove 311, but it does not completely lock the round rod 310. The round rod 310 can rotate but cannot be raised or lowered to adjust its height, so you can focus on adjusting the rotation angle without worrying about changes in height during rotation. In the unlocked state, the set screw 500 is completely disengaged from the annular groove 311, so the round rod 310 can be raised, lowered, and rotated freely.

[0046] Additionally, it is understandable that the annular grooves 311 are arranged vertically to achieve stepped height adjustment. Furthermore, since the set screws 500 are embedded in the annular grooves 311, compared to not having annular grooves 311 and only relying on the frictional force of the contact between the outer cylindrical surface of the round rod 310 of the set screws 500 and the annular grooves 311, the set screws 500 embedded in the annular grooves 311 do not rely on frictional force to fix the height position of the round rod 310. Instead, the height position of the round rod 310 is fixed through structural locking. Furthermore, the prism mounting bracket 400 is threadedly connected to the threaded post 320, allowing for stepless height adjustment within a range by rotating the prism mounting bracket 400. This enables coarse height adjustment by embedding the set screw 500 into the annular groove 311 at different heights, and fine height adjustment by rotating the prism mounting bracket 400. The combination of these two adjustments achieves highly efficient and precise prism 600 position adjustment. Once the prism 600 is in the correct height adjustment position, the rotating set screw 500 does not interfere with the rotation adjustment of the round rod 310, thus driving the prism 600 to rotate to the appropriate angle. Finally, tightening the set screw 500 switches it to the locked state.

[0047] Reference Figure 3In a further embodiment of this utility model, a screw head 330 is connected between the round rod 310 and the threaded column 320. The outer diameter of the screw head 330 is larger than that of the threaded column 320 and the sleeve rod 200, thereby limiting the depth of the round rod 310 inserted into the sleeve rod 200. The screw head 330 is also convenient for manual operation to rotate or lift and adjust its position.

[0048] Reference Figure 4 In a further embodiment of this utility model, when the screw head 330 abuts against the upper end of the sleeve 200, the uppermost annular groove 311 aligns with the second threaded hole 220, thereby facilitating the determination of whether the uppermost annular groove 311 and the second threaded hole 220 are aligned, and after alignment, the set screw 500 is screwed into the uppermost annular groove 311.

[0049] Reference Figure 5 In a further embodiment of this utility model, when the bottom wall of one annular groove 311 is flush with the upper end of the sleeve rod 200, the adjacent annular groove 311 below is aligned with the second threaded hole 220. This makes it easy to determine whether the lower annular groove 311 and the second threaded hole 220 are aligned. After alignment, the set screw 500 is tightened to embed it into the lower adjacent annular groove 311. This avoids the set screw 500 being tightened without being aligned with the annular groove 311 and thus not being tightly pressed against the circumference of the round rod 310, avoiding the need for repeated operation and adjustment.

[0050] Reference Figure 3 In a further embodiment of this utility model, the outer peripheral wall of the sleeve 200 is provided with a cylindrical protrusion 230 corresponding to the second threaded hole 220. The second threaded hole 220 extends to the end face of the cylindrical protrusion 230. The cylindrical protrusion 230 can delay the length of the second threaded hole 220, thereby ensuring a threaded connection with a sufficient length with the set screw 500, avoiding insufficient thread turns, which can easily lead to stress concentration and damage to the thread teeth.

[0051] Reference Figure 3 In a further embodiment of this utility model, the chassis 100 is provided with an inclined sleeve 130, and the armrest 120 is provided with a plug 121. The plug 121 is inserted into the sleeve 130 and fixed, thereby facilitating installation and fixation. The sleeve 130 facilitates the insertion and positioning of the plug 121. The plug 121 and the sleeve 130 can be fixed by fasteners or welding. For example, a fixing screw is installed on the peripheral wall of the sleeve 130. The fixing screw passes through the peripheral wall of the sleeve 130 and abuts against the plug 121, thereby fixing the position of the plug 121.

[0052] Reference Figure 4 In a further embodiment of this utility model, a preload nut 340 is threaded onto the threaded post 320. The preload nut 340 is used to abut against the prism mounting bracket 400, thereby achieving preload on the prism mounting bracket 400, so that the prism mounting bracket 400 cannot be easily rotated and its position changed.

[0053] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
