The arc-shaped plate is connected to the extended end of the elastic member and protrudes from the inner side wall of the wheel frame plate. The arc-shaped plate is used to abut and cooperate with the outer peripheral wall of the end plate.

[0008] In some embodiments, the side cavity is located at the lower part of the wheel frame plate, and the side cavity is arranged away from the unwinding side of the retracting wheel, and the upper and lower side edges of the arc plate are respectively slidably matched with the two side walls of the side cavity.

[0027] Please also refer to Figures 1 to 6 The present invention now provides an engineering surveying instrument for architectural planning. The instrument comprises a weighted base 1, a telescopic support column 2, a supporting platform 3, a retractable wheel 4, and a level 5. The bottom of the weighted base 1 is provided with a downwardly opening accommodating chamber 11. The telescopic support column 2 is provided with a plurality of columns, each hinged within the accommodating chamber 11. The telescopic support column 2 is capable of vertical swinging and supported below the weighted base 1. The retractable wheel 4 is rotatably connected to the top of the weighted base 1. The supporting platform 3 is connected to the weighted base 1 and mounted above the retractable wheel 4. The level 5 is rotatably connected to the top surface of the supporting platform 3.

[0028] The present embodiment provides an engineering surveying instrument for building planning. Compared with the prior art, the present embodiment provides an engineering surveying instrument for building planning. A accommodating cavity 11 is provided at the bottom of the weighted base 1. When the retractable wheel 4 needs to be used for unwinding, the telescopic support column 2 is retracted into the accommodating cavity 11, so that the retractable wheel 4 is in a lower position; when the level 5 needs to be used, the telescopic support column 2 is opened so that it is supported under the weighted base 1 to meet the operator's usage needs. The above device meets different needs such as length measurement and height difference measurement, is simple and easy to carry, easy to operate, and has good practicality.

[0029] In this embodiment, the weighted base 1 can be made of a metal material such as stainless steel, providing a certain weight and providing a stable base suitable for use on soft soil. The telescopic support column 2 can be adjusted to accommodate measurements at different heights, ensuring the normal use of the level 5, reducing the overall footprint of the device and making it easier for operators to carry.

[0030] The above device can meet the measurement operations of length and height difference in building planning projects, meet various measurement needs, and has good practicality.

[0031] In one possible implementation, see Figures 1 to 6 The retracting wheel 4 includes a wheel axle 41 for winding a scale 46 and two end plates 42 connected to the two ends of the wheel axle 41 in a one-to-one manner. Two parallel wheel frame plates 43 are provided on the weight base 1. The two ends of the retracting wheel 4 are respectively connected to the wheel frame plates 43 in a one-to-one manner. A driving hand wheel 44 is provided at one end of the wheel axle 41. An elastic pressure component 6 is provided on the inner wall of the wheel frame plate 43, which slides with the outer peripheral wall of the end plate 42 of the retracting wheel 4. The elastic pressure component 6 is on the outer peripheral wall of the end plate 42 to limit the circumferential rotation of the retracting wheel 4.

[0032] In this embodiment, the space between the two end plates 42 on the outer periphery of the axle 41 is used to wind a scale 46. The surface of the wheel frame plate 43 extends in the vertical direction and is used to mount the ends of the axle 41. The ends of the axle 41 are rotatably connected to the wheel frame plate 43. The retractable wheel 4 is driven by a drive handwheel 44 connected to the end of the axle 41. The drive handwheel 44 extends in the horizontal direction, facilitating subsequent operations such as unwinding and rewinding by the operator.

[0033] On this basis, the elastic pressure component 6 provided on the inner side of the wheel frame plate 43 can exert an elastic pushing effect on the outer peripheral wall of the end plate 42, thereby pressing against the outer peripheral wall of the end plate 42 to limit the circumferential rotation of the retractable and unreeling wheel 4. When unwinding or rewinding is required, the operator operates the driving hand wheel 44 to overcome the low pressure of the elastic pressure component 6 on the end plate 42, thereby driving the retractable and unreeling wheel 4 to rotate, achieving the unwinding or rewinding operation.

[0034] When the operator releases the driving hand wheel 44, the elastic pressing component 6 can press against the outer peripheral wall (that is, the outer peripheral edge position) of the end plate 42, so that the retracting wheel 4 can be stably in a certain position, avoiding its own rotation causing the change of the unwinding length of the scale 46, making it easier for the operator to measure the ground length.

[0035] For some examples, see Figures 1 to 6A side cavity 45 for accommodating an elastic pressure assembly 6 is provided on the inner wall of the wheel frame plate 43. The elastic pressure assembly 6 includes an elastic member 61 and an arc-shaped plate 62. Several elastic members 61 are provided in the side cavity 45 and are arranged at intervals along the circumference of the retracting and unretracting wheel 4. The elastic member 61 extends toward the axial side of the retracting and unretracting wheel 4. The arc-shaped plate 62 is connected to the extended end of the elastic member 61 and protrudes from the inner side wall of the wheel frame plate 43. The arc-shaped plate 62 is used to abut and cooperate with the outer peripheral wall of the end plate 42.

[0036] In this embodiment, the side cavity 45 provided on the wheel carrier plate 43 is used to accommodate an elastic member 61. The elastic member 61 pushes the curved plate 62 against the outer peripheral wall of the end plate 42. The curved plate 62 protrudes from the inner side wall of the wheel carrier plate 43, that is, extends toward the adjacent sides of the two wheel carrier plates 43, ensuring full contact with the outer peripheral wall of the end plate 42, forming a good elastic pressing effect. When the operator releases the driving handle, the elastic pressing assembly 6 can form a circumferential limit for the retractable and retractable wheel 4.

[0037] For some examples, see Figures 1 to 6 The side cavity 45 is located at the lower part of the wheel frame plate 43, and the side cavity 45 is set away from the unwinding side of the rewinding wheel 4. The upper and lower side edges of the arc plate 62 slide with the side walls of the side cavity 45 respectively. The side cavity 45 is set at the lower part of the wheel frame plate 43, which can form an effect of elastically pressing the outer peripheral wall of the end plate 42 obliquely upward. The end plate 42 is able to slide with the side cavity 45 under the elastic force of the elastic member 61. The side walls of the side cavity 45 form a limiting effect on the arc plate 62, ensuring that it can move along the radial direction of the rewinding and unwinding, forming an elastic pressing effect on the end plate 42, thereby ensuring the stability of the position of the scale 46 during the length measurement process, eliminating the tedious need for the operator to hold it with his hands, and also improving the measurement accuracy.

[0038] In one possible implementation, see Figures 1 to 6 A first level 34 and a second level 35 are provided on the top surface of the support platform 3. The first level 34 and the second level 35 are arranged perpendicular to each other. The first level 34 and the second level 35 facilitate the leveling operation of the support platform 3. By adjusting the height of the telescopic support column 2, the support platform 3 is kept in a horizontal state, ensuring the accuracy of subsequent height difference measurements.

[0039] In one possible implementation, see Figures 1 to 6 The telescopic support column 2 includes a telescopic rod 21 and a sleeve leg 22. The sleeve leg 22 is slidably sleeved on the outer end of the telescopic rod 21 and threadedly engaged with the telescopic rod 21. The extending end of the sleeve leg 22 is provided with a conical tip 23 for inserting into the ground.

[0040] In this embodiment, the telescopic support column 2 is formed by combining a telescopic rod 21 and a sleeve leg 22. The sleeve leg 22 is mounted on the outer circumference of the telescopic rod 21. The two can be threaded together to adjust the axial position, thereby achieving the effect of adjusting the height of the telescopic support column 2. The tapered tip 23 at the outer end of the sleeve leg 22 can be stably inserted into the ground, ensuring the firmness of the bottom installation and providing a good support effect.

[0041] For some examples, see Figures 1 to 6 The outer circumference of the telescopic rod 21 is provided with an external thread 24, which is arranged at the extended end of the telescopic rod 21. The inner wall of the sleeve leg 22 is provided with a first internal thread 25 and a second internal thread 26, respectively. The first internal thread 25 is located at the extended end of the sleeve leg 22, and the second internal thread 26 is located at the end of the sleeve leg 22 near the telescopic rod 21. Specifically, the external thread 24 on the outer circumference of the threaded rod can be selectively connected to the first internal thread 25 or the second internal thread 26 in the sleeve leg 22, which can achieve fine adjustment of the height through threaded matching.

[0042] When a large height adjustment is required, the following method can be selected: when the external thread 24 and the first internal thread 25 cooperate with each other, the height of the telescopic support column 2 is low; when the external thread 24 and the second internal thread 26 cooperate with each other, the height of the telescopic support column 2 is high. By using the above method, a large height adjustment of the telescopic support column 2 can be achieved.

[0043] In one possible implementation, see Figures 1 to 6 The support platform 3 is connected to the top surface of the weighted base 1 via four upright posts 31. A rotary drive 7 is provided at the bottom of the support platform 3 for rotating the level 5. The support platform 3 is connected to the top surface of the weighted base 1 via four upright posts 31 arranged in a rectangular pattern. The top surface of the support platform 3 is used to support the level 5. The level 5 can be adjusted in angle to correspond to different directions and is driven by the rotary drive 7.

[0044] For some examples, see Figures 1 to 6 The bottom of the level 5 is provided with a downward extending limit cylinder 51, and the supporting platform 3 is provided with a limit ring 32 located in the limit cylinder 51 and slidingly cooperating with the limit cylinder 51 along the circumferential direction. The rotating drive component 7 has a drive shaft 71 extending upward and passing through the supporting platform 3 and the limit cylinder 51. The drive shaft 71 is connected to the bottom wall of the level 5.

[0045] In this embodiment, the limiting cylinder 51 is sleeved on the outer periphery of the limiting ring 32 and slides with the limiting ring 32 along the circumferential direction. The setting of the limiting cylinder 51 and the limiting ring 32 can realize the limitation of the relative position of the level 5 and the supporting platform 3, thereby preventing the horizontal position of the level 5 on the supporting platform 3 from being displaced.

[0046] On this basis, an axially extending annular groove 52 is provided on the inner wall of the limiting cylinder 51, and a circumferentially extending annular strip 33 is provided on the outer periphery of the limiting ring 32. The annular strip 33 is slidably connected in the annular groove 52. The two cooperate with each other to limit the axial position of the limiting cylinder 51 and the limiting ring 32, thereby preventing the level 5 from falling off from above the limiting ring 32 and ensuring the reliability of the connection.

[0047] In one possible implementation, see Figures 1 to 6 A handle 8 is hingedly connected to the supporting platform 3, and the two ends of the handle 8 are respectively hingedly connected to the two side walls of the supporting platform 3. The setting of the handle 8 facilitates the carrying of the device and improves the convenience of carrying and transferring.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
