Description

Technical Field

[0001] The present invention relates to the technical field of inspection of existing doors, windows and curtain walls, and particularly relates to a measuring device for the lapping amount in a narrow gap of an existing door, window and curtain wall. Background Art

[0002] In China, there are more and more building curtain walls that have reached the designed service life among existing curtain walls, and the safety of existing curtain walls has attracted more and more attention from all parties. If the size of the glass inserted into the groove in a stick-built glass curtain wall or aluminum alloy doors and windows in existing curtain walls is too small, the glass is likely to fall out of the groove, resulting in the glass falling. The lapping amount between the upper and lower cross beams of an existing unitized curtain wall is crucial. If the lapping amount is too small, a small amount of up and down movement of the panel will cause the upper and lower cross beams to fall out of the insertion groove, resulting in the overall fall of the unit panel. The lapping amount dimensions of the two components in the narrow gap (a 2-6 mm gap) need to be measured at the above inspection parts to determine whether the lapping of the components is safe. However, since the situation inside the narrow gap cannot be observed from the outside, the existing traditional measuring tools cannot measure the lapping amount inside the narrow gap. If an industrial endoscope is used for inspection, due to the large size of the endoscope lens, it cannot be inserted into the narrow gap to observe the internal situation. Therefore, there is an urgent need for a measuring device that can measure the lapping amount in the narrow gap of an existing door, window and curtain wall. Summary of the Invention

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] This embodiment relates to a measuring device for the lap amount in a narrow gap of an existing door, window and curtain wall, and its structure is as Figures 1-4 shown. The measuring device includes a sheet-shaped measuring ruler 1, a sliding piece 2, a first spring piece 3, a second spring piece 4, a buckle structure and a scale line 9;

[0034] The sheet-shaped measuring ruler 1 and the sliding piece 2 are slidably connected. The connection method selected in this embodiment is as Figure 5 shown. A groove is provided on the sheet-shaped measuring ruler 1, and a protrusion is provided on the sliding piece 2. The protrusion and the groove are matched to complete the sliding connection between the sheet-shaped measuring ruler 1 and the sliding piece 2;

[0035] One end of the first spring sheet 3 and the second spring sheet 4 are respectively connected to the sliding sheet 2, and the other end is respectively connected to the sheet-shaped measuring ruler 1; the elastic force of the first spring sheet 3 in this embodiment is greater than the elastic force of the second spring sheet 4; the provision of the second spring sheet 4 reduces the loss of the sheet-shaped measuring ruler 1 and the sliding sheet 2;

[0036] The buckle structure includes a buckle base 5 and a buckle 6. The buckle base 5 is fixedly connected to the sliding sheet 2. The buckle 6 is rotatably connected to the buckle base 5. A guide groove 8 for guiding the buckle 6 is provided on the sheet-shaped measuring ruler 1. The buckle 6 is located in the guide groove 8.

[0037] In this embodiment, both the buckle base 5 and the buckle 6 are block structures, and their thicknesses are greater than the thicknesses of the sheet measuring ruler 1 and the sliding sheet 2. Through such a configuration, the user can directly move the buckle base 5 to achieve relative sliding of the sheet measuring ruler 1 and the sliding sheet 2, and then directly move the buckle 6 to connect it to the slot 7 or remove it from the slot 7, making the measuring device more convenient to use.

[0038] The sheet measuring ruler 1 in this embodiment is further provided with a scale line 9, and the setting direction of the scale line is perpendicular to the relative sliding direction of the sheet measuring ruler 1 and the sliding sheet 2. The scale line 9 in this embodiment is arranged at one end of the sheet measuring ruler 1 where the card slot 7 is arranged, and the lower edge of the first spring sheet 3 corresponds to the zero scale position on the scale line 9, so that the user can read the data conveniently.

[0039] The structure of the measuring device in this embodiment when in the measuring state is as follows Figures 6-9 As shown, the buckle 6 is connected to the slot 7, the first spring leaf 3 is in a bent state, and the second spring leaf 4 is in a straight state.

[0040] The specific method of using the measuring device in this embodiment to measure the insertion amount of the upper and lower beams of the existing curtain wall is as follows:

[0041] First, the scale line 9 is facing the user, and the buckle 6 is at the bottom of the device. Since the elastic force of the first spring sheet 3 is greater than the elastic force of the second spring sheet 4, when the buckle 6 is not engaged with the slot 7, the sliding sheet 2 in the natural state is pressed against the side wall of the sheet measuring ruler 1. Figures 2-4 As shown, at this time, the second spring sheet 4 is in a bent state due to compression, and the first spring sheet 3 is in a slightly bent state, but the bending degree does not exceed the narrow gap width range. The top protrusion and the bottom protrusion of the sliding sheet 2 are both located in the groove of the sheet-shaped measuring ruler 1, and can move toward the slot 7 under the action of external force.

[0042] like Figure 10As shown, when the measuring device is in use, the sheet-shaped measuring scale 1 is inserted into the narrow slit from bottom to top. The first spring piece 3 is slightly bent but does not exceed the width range of the narrow slit, so it can be smoothly inserted into the narrow slit. The buckle base 5 and the buckle are not inserted into the narrow slit.

[0043] When the sheet-shaped measuring scale 1 is inserted to the top of the narrow slit until it can no longer be moved upward, the buckle base 5 is toggled to drive the sliding piece 2 to slide until the buckle 6 is engaged with the card slot 7. As Figures 7-9 shown, at this time, the second spring piece 4 is in a straight state and the first spring piece 3 is in a bent state. The measuring device is moved downward until the first spring piece 3 abuts against the top of the upper cross beam of the unit plate and cannot be moved downward, as Figure 11 shown. Since the zero scale position of the scale line 9 is aligned with the lower edge of the first spring piece 3, the zero scale position is also aligned with the upper cross beam of the unit plate at this time. At this time, the user can directly read the scale corresponding to the bottom of the lower cross beam of the unit plate from the scale line 9 of the sheet-shaped measuring scale 1, and this scale is the lap joint dimension α between the lower cross beam of the unit plate in the narrow slit and the upper cross beam 9 of the unit plate.

[0044] After reading the reading, the buckle 6 is toggled to release its engagement with the card slot 7, and then the buckle base 5 is toggled until the sliding piece 2 is naturally pressed against the side wall of the sheet-shaped measuring scale 1. At this time, the first spring piece 3 is in a slightly bent state but does not exceed the width range of the narrow slit, so the measuring device can be withdrawn from the narrow slit. At this time, the measuring device returns to its initial state. Thus, one measurement of the lap joint amount is completed.

[0045] As mentioned above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
