Description

Technical Field

[0001] This utility model relates to the field of length setting instruments, and in particular to a bridge ruler bracket for a length setting instrument. Background Technology

[0002] The length setting instrument can calibrate the bridge gauge, but there is currently no good tool for supporting and fixing deeper bridge gauges, which makes the calibration process inconvenient and has poor adaptability to bridge gauges of different depths. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a bridge ruler bracket for a length setting instrument, which can provide a bridge ruler bracket for the length setting instrument, adapt to bridge rulers of different depths, is very convenient to use, and makes calibration more accurate.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a bridge ruler bracket for a length setting instrument, including a base, a first support plate, a second support plate and a support rod;

[0005] The two ends of the base are respectively fixed to the lower ends of the first support plate and the second support plate.

[0006] The first and second support plates are distributed relative to each other;

[0007] The first support plate has a plurality of threaded holes horizontally arranged from bottom to top, and the second support plate has a plurality of through holes horizontally arranged from bottom to top. The threaded holes and the through holes correspond one-to-one and are coaxially arranged.

[0008] The support rod passes through the through hole, and the front end of the support rod is provided with an external thread section that matches the threaded hole.

[0009] The crossbar will be adapted to the corresponding threaded hole in different through holes to change the different support height of the support rod.

[0010] When using it, fix the base to the length setting instrument, set a bridge ruler bracket on the left and right sides respectively, and then place the two ends of the bridge ruler on the support rods of the two bridge ruler brackets respectively. According to the different depths of the bridge ruler, change the support rods to fit different through holes and threaded holes, that is, change the height of the support rods.

[0011] If the bridge gauge has a large depth, the support rod should be adapted to the higher through hole and threaded hole.

[0012] Preferably, the rear end of the support rod is provided with a handle, which facilitates the installation of the support rod into the through hole and the threaded hole.

[0013] Preferably, the diameter of the handle is larger than the diameter of the through hole, so as to limit the position of the support rod installed in the through hole.

[0014] Preferably, the spacing between adjacent through holes is the same. This makes it easy to visually understand the increase in height caused by changing the position of the support rod upwards.

[0015] Preferably, both ends of the base are connected to the lower ends of the first support plate and the second support plate respectively by bolts. This makes the connection more secure and stable.

[0016] Preferably, a limiting platform is provided on the inner side of the first support plate and the second support plate corresponding to the upper surface of the base. This makes it easier to determine the fixed position of the first support plate and the second support plate on the base.

[0017] Preferably, the base has connecting plates at both ends pointing downwards, facilitating connection to a length setting device.

[0018] Preferably, a first support plate and a second support plate, perpendicular to the vertical direction of each of the through holes, are horizontally provided with a first light-transmitting hole, and the side wall of the support rod is provided with a second light-transmitting hole corresponding to the first light-transmitting hole. When the support rod is rotated, and the first and second light-transmitting holes coincide, the other set of bridge ruler supports also aligns the angles of the first and second light-transmitting holes. Then, a laser beam is shone from the light-transmitting hole of one set of bridge ruler supports to the light-transmitting hole of the other set. If the light can pass through, it indicates that the support rods of the two sets of bridge ruler supports are at the same height, and the rotation angle at which the support rods provide support is relatively fixed, further ensuring that the support rods on both sides are kept as horizontal as possible.

[0019] The beneficial effects of this utility model are:

[0020] This solution provides a bridge ruler bracket for the length setting instrument, which can accommodate bridge rulers of different depths, making it very convenient to use and enabling more accurate calibration. Attached Figure Description

Detailed Implementation

[0026] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0027] Example

[0028] like Figure 1 As shown, a bridge ruler bracket for a length setting instrument includes a base 1, a first support plate 2, a second support plate 3, and a support rod 4. The two ends of the base 1 are fixed to the lower ends of the first support plate 2 and the second support plate 3, respectively. The first support plate 2 and the second support plate 3 are distributed opposite to each other. The first support plate 2 has a plurality of threaded holes 5 horizontally arranged from bottom to top, and the second support plate 3 has a plurality of through holes 6 horizontally arranged from bottom to top. The threaded holes 5 and the through holes 6 correspond one-to-one and are coaxially arranged. The support rod 4 passes through the through holes 6, and the front end of the support rod 4 has an external thread section adapted to the threaded holes 5.

[0029] The crossbar will be adapted to the corresponding threaded hole 5 in different through holes 6 to change the different support heights of the support rod 4.

[0030] Combination Figure 2 As shown, when in use, the base 1 is fixed on the length setting instrument 12, and a bridge ruler 13 bracket is set on the left and right respectively. Then, the two ends of the bridge ruler 13 are placed on the support rods 4 of the two bridge ruler 13 brackets respectively. According to the different depths of the bridge ruler 13, the support rods 4 are adapted to different through holes 6 and threaded holes 5, that is, the height of the support rods 4 is changed.

[0031] If the bridge gauge 13 has a large depth, the support rod 4 will be adapted to the higher through hole 6 and threaded hole 5.

[0032] The support rod 4 has a handle 7 at its rear end, which facilitates mounting the support rod 4 into the through hole 6 and the threaded hole 5.

[0033] The diameter of the handle 7 is larger than the diameter of the through hole 6, so as to limit the position of the support rod 4 when it is installed in the through hole 6.

[0034] The spacing between adjacent through holes 6 is the same. This makes it easy to visually understand the increase in height caused by changing the position of the support rod 4 upwards.

[0035] The two ends of the base 1 are respectively connected to the lower ends of the first support plate 2 and the second support plate 3 by bolts. The connection is more secure and stable.

[0036] A limiting platform 8 is provided on the inner side of the first support plate 2 and the second support plate 3 corresponding to the upper surface of the base 1. This makes it easier to determine the fixed position of the first support plate 2 and the second support plate 3 on the base 1.

[0037] The base 1 has connecting plates 9 at both ends facing downwards, which facilitates connection with the length setting device 12.

[0038] Example 2

[0039] Combination Figure 3 As shown, compared to Embodiment 1, this embodiment also includes the following differences: the first support plate 2 and the second support plate 3, which are perpendicular to the vertical direction of each of the through holes 6, are horizontally provided with a first light-transmitting hole 10, and the side wall of the support rod 4 is provided with a second light-transmitting hole 11 corresponding to the first light-transmitting hole 10. When the support rod 4 is rotated, when the first light-transmitting hole 10 and the second light-transmitting hole 11 coincide, the other set of bridge ruler 13 brackets also align the angles of the first light-transmitting hole 10 and the second light-transmitting hole 11. Then, a laser is used to irradiate the light-transmitting hole of one set of bridge ruler 13 brackets into the light-transmitting hole of the other set of bridge ruler 13 brackets. If the light can pass through, it indicates that the support rods 4 of the two sets of bridge ruler 13 brackets are at the same height, and the angle of rotation that allows the support rods 4 to provide support is relatively determined, further ensuring that the support rods 4 on both sides are kept as close to the same horizontal line as possible.

[0040] The beneficial effects of this utility model are:

[0041] This solution provides a bridge ruler 13 bracket for the length setting instrument 12, which can adapt to bridge rulers 13 of different depths, making it very convenient to use and more accurate in calibration.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
