Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-4 , a convenient-to-carry on-site measurement device for project cost, including a measuring wheel 1. A support frame 2 is arranged on the outer surface of the measuring wheel 1. A support rod 3 is inserted on one side of the support frame 2. The support rod 3 is divided into multiple sections, and the multiple sections of the support rod 3 are threadedly connected. The bottom end of the lowermost support rod 3 is fixedly installed with an insertion block 4, and the insertion block 4 is inserted into the support frame 2. A chute 301 is opened in the middle of the support rod 3, and a sliding plate 302 is slidably connected inside the chute 301. The top end of the sliding plate 302 is hinged with a chain 303, and the top end of the chain 303 is connected to the bottom end of the upper section of the support rod 3.

[0025] The length of a single section of the chain 303 is greater than the outer diameter of the support rod 3, and the number of each group of the chains 303 is at least three. Through such a setting, it can be ensured that when the chain 303 is stretched to the uppermost position, the two support rods 3 can be made parallel by rotation, so as to reduce the space occupied after folding.

[0026] Above the side wall of the support frame 2, there is a socket groove 5. The socket block 4 is inserted into the inside of the socket groove 5. On both sides of the support frame 2, there is a sliding connection with a stop block 6. The stop block 6 is inserted into the socket block 4. The stop block 6 and the support frame 2 are fixedly connected by a tension spring 7. Through such a setting, the connection between the socket block 4 and the support frame 2 can be achieved and it is ensured that they are not easily separated. Only by pulling the stop blocks 6 simultaneously to both sides can the two mechanisms be separated.

[0027] On the outer surface of the top end of the support rod 3, there is a threaded groove 8. The outer surface of the threaded groove 8 is threadedly connected with a limit threaded sleeve 9. The upper end of the limit threaded sleeve 9 covers above the sliding groove 301. The limit threaded sleeve 9 and the support rod 3 are inserted by a threaded pin shaft. Through such a setting, the sliding plate 302 can be limited. After the sliding plate 302 is inserted into the inside of the sliding groove 301, then the limit threaded sleeve 9 is threadedly connected to the outer surface of the support rod 3. Through such a setting, it is convenient for assembly.

[0028] Below the threaded groove 8 of the support rod 3, there is a fixedly installed threaded outer sleeve 10. The outer surface of the bottom end of the upper section of the support rod 3 is rotatably connected with a threaded inner sleeve 11. The threaded inner sleeve 11 is threadedly connected to the threaded outer sleeve 10. Through such a setting, threaded connection can be achieved.

[0029] The cross-sectional shape of the threaded inner sleeve 11 is "convex". The thread of the threaded inner sleeve 11 is opened on the inner side of the larger diameter at the lower part. There are two sets of retaining rings 12 sleeved on the outer surface of the support rod 3. The upper retaining ring 12 is located above the threaded inner sleeve 11, and the lower retaining ring 12 is located at the lowermost part of the outer surface of the support rod 3. The retaining ring 12 and the support rod 3 are inserted by a threaded pin shaft. Through such a setting, it can be used to limit the moving range of the threaded inner sleeve 11.

[0030] On the outer surface of the uppermost support rod 3, there is a threaded connection with a handle 13. In the middle of the support rod 3, there is a telescopic lock to adjust the length of a single-section support rod 3. Through such a setting, the support rod 3 can adjust its length and is more comfortable to hold.

[0031] One end of the tension spring 7 away from the stop block 6 is fixedly installed with a connecting plate 14. The connecting plate 14 and the support frame 2 are inserted by a threaded pin shaft. Through such a setting, it can be ensured that the installation between the tension spring 7 and the connecting plate 14 is convenient.

[0032] During use, by setting threaded connections between multiple sections of the support rod 3 and arranging a chain 303 that can slide relative to each other between the inner walls of the support rod 3, the separated multi-section support rods 3 are connected relatively and placed in parallel, so as to reduce the problem of the space occupied by the support rod 3 after contraction. At the same time, setting the chain 303 can avoid the problem that ropes are easily entangled when connected by ropes.

[0033] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0034] As mentioned above, the above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
