[0002] In the building engineering construction process, the flatness and parallelism of the building surface are one of important indexes for measuring construction quality, especially when installing precise components such as curtain wall, door and window, pipeline, the parallelism requirement of the building surface is higher.
[0003] The traditional parallelism detection method usually relies on surveying tools such as level, laser level or ruler, and the level and other equipment mainly measure overall inclination, and the detection effect of local slight concave-convex is poor, and local uneven areas cannot be effectively identified. UTILITY MODEL CONTENT
[0004] In view of the deficiencies of the prior art, the utility model provides a building engineering with building parallelism detection device.
[0005] In order to realize the above-mentioned purpose, the technical scheme of the utility model is as follows:
[0006] A building engineering with building parallelism detection device, the cavity is set in the length direction of the shell, the cavity of the shell is fixed with the clamping tooth on the opposite side wall;
[0007] The cavity of the shell is provided with a connecting block sliding along the length direction of the cavity, the connecting block is provided with a clamping block acting on the clamping tooth on both sides of one end;
[0008] When the shell is close to the building, the clamping block close to the building is connected with the roller penetrating the shell and abutting on the building surface, the clamping block away from the building is connected with the spring sheet extruding the connecting block towards the building direction, when the roller contacts the uneven building, the clamping block is clamped on one side clamping tooth.
[0009] Preferably, the abutting surface of the clamping tooth and the clamping block is the concave arc groove structure, and the inclination of the two ends of the arc groove structure is greater than that of the middle part.
[0010] Preferably, the end of the connecting block away from the clamping block is fixed with the limiting rod penetrating the side wall of the shell.
[0011] Preferably, the side wall of the connecting block close to the clamping block one end is slidingly connected with the pull rod through the penetrating circular arc groove, the middle part of the pull rod is slidingly connected with the circular arc groove, and both ends penetrate and extend out of the side wall of the shell.
[0012] Preferably, the circular arc groove is the arc structure with the axis of the limiting rod as the center.
[0013] Preferably, the two sides of the shell close to the building are fixed with the fitting feet, and the end of the roller away from the shell is coplanar with the end of the fitting feet away from the shell.
[0014] Compared with the prior art, the building parallelism detection device has the following beneficial effects:
[0015] 1.

[0016] 2. Since the inclination of the two ends of the clamping tooth is greater than the middle part, the sliding resistance of the clamping block in the groove increases with the increase of the offset angle, so that the unevenness of the surface of the building is enhanced, and the detection personnel can directly judge the wall surface flatness through the force feedback of the lever, thereby improving the detection efficiency.

[0026] It is easy to understand that according to the technical scheme of the utility model, a plurality of structure modes and implementation modes which can be replaced with each other can be proposed by the general skilled in the art without changing the essential spirit of the utility model. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole of the utility model or regarded as the limitation or restriction of the technical scheme of the utility model.
[0027] Embodiment
[0028] As Figures 1-4 shown, a building parallelism detection device for constructional engineering, comprising a shell 11, the two sides of the shell 11 near a side of the building are both fixed with a fitting foot 12, the end of the roller 223 away from the shell 11 is coplanar with the end of the fitting foot 12 away from the shell 11, the fitting foot 12 can provide additional support, so that the device is more stable on the surface of the building, avoiding measurement error caused by shaking. The coplanar design of the fitting foot 12 and the roller 223 ensures that the device can uniformly contact the surface of the building during measurement, thereby ensuring the measurement accuracy and avoiding the influence of the device inclination on the measurement results.
[0029] In one of the embodiments, as Figures 2-4 shown, a cavity is formed in the shell 11 along the length direction thereof, the opposite two side walls of the cavity of the shell 11 are both fixed with a clamping tooth 111, the cavity of the shell 11 is provided with a connecting block 22 sliding along the length direction of the cavity, the two sides of one end of the connecting block 22 are both provided with a clamping block 221 acting on the clamping tooth 111, when the shell 11 is close to the building, the clamping block 221 close to the building is connected with a roller 223 penetrating through the shell 11 and abutting against the surface of the building, the clamping block 221 away from the building is clamped with a spring sheet 24 pressing the connecting block 22 towards the building, when the roller 223 contacts the uneven building, the clamping block 221 is clamped with one of the clamping teeth 111.
[0030] When the parallelism of the building needs to be detected, the two fitting feet 12 of the detection device are pasted on the surface of the building, which can make the roller 223 abut against the surface of the building. The connecting block 22 is moved by the driving of the driving rod 23, and the position is stabilized by the limiting rod 21 during the movement of the connecting block 22. If the surface of the building is parallel, the position of the connecting block 22 and the roller 223 will not change during the movement, and the clamping block 221 can stably slide between the two clamping teeth 111.
[0031] When the roller 223 passes through the uneven (either outward convex or inward concave) building surface, the building surface changes the effective length of the connecting block 22 through the roller 223, at this time, the connecting block 22 rotates around the limiting rod 21 under the action of the spring sheet 24, the connecting block 22 drives the roller 223 to rotate, so that the rotated roller 223 still adheres to the building surface, but at this time, the position of the clamping block 221 relative to the clamping teeth 111 changes due to the rotation of the connecting block 22, so that the clamping block 221 is clamped in one of the clamping teeth 111, in order to make the clamping block 221 continuously move with the connecting block 22, a larger force needs to be applied to the push rod 23 when the clamping block 221 is clamped in the clamping teeth 111, so that the clamping block 221 can be moved out of the clamping teeth 111, at this time, the force applied to the push rod 23 changes, which can be used to judge the parallelism of the wall surface.
[0032] If the building surface is inwardly concave, the clamping block 221 will be clamped in the clamping teeth 111 close to the building, at this time, increasing the force applied to the push rod 23 can make the connecting block 22 drive the spring sheet 24 to compress, so that the clamping block 221 slides out of the clamping teeth 111; if the building surface is outwardly convex, the clamping block 221 will be clamped in the clamping teeth 111 away from the building, at this time, increasing the force applied to the push rod 23, since the roller 223 cannot move, if the clamping block 221 needs to be slid out of the clamping teeth 111, the adhering foot 12 needs to be separated from the building surface. Thus, the parallelism of the building surface and the specific situation of the building surface can be detected.
[0033] In one embodiment, as shown in Figures 2-4 the clamping surface of the clamping teeth 111 and the clamping block 221 is a concave arc-shaped groove structure, the inclination of the two ends of the arc-shaped groove structure is greater than the inclination of the middle part, since the inclination of the two ends of the arc-shaped groove structure is greater, a greater force of the push rod 23 is needed when the clamping block 221 slides out of the clamping teeth 111, thereby providing more obvious force feedback.
[0034] In one embodiment, as shown in Figures 2-4 the end of the connecting block 22 away from the clamping block 221 is fixed with a limiting rod 21 penetrating through the side wall of the shell 11, the limiting rod 21 is used to constrain the movement track of the connecting block 22, so that it rotates or slides around the limiting rod 21. Through the fixing action of the limiting rod 21, the connecting block 22 can stably deflect when the roller 223 is affected by the uneven surface, so that the roller 223 always adheres to the building surface, and the measurement accuracy is improved.
[0035] In one embodiment, as shown in Figure 3As shown, the side wall of the connecting block 22 near one end of the card block 221 is slidably connected with a pull rod 23 through a through arc-shaped slot 222, the middle part of the pull rod 23 is slidably connected with the arc-shaped slot 222, and both ends penetrate and extend out of the side wall of the shell 11. Through the sliding connection of the pull rod 23 in the arc-shaped slot 222, the operator can exert an external force to drive the connecting block 22 to slide, thereby improving the operation convenience of the detection device. The arc-shaped slot 222 is an arc structure with the axis of the limiting rod 21 as the center, so that the sliding direction of the pull rod 23 in the slot is consistent with the rotating direction of the connecting block 22. The limiting rod 21 serves as the center of the arc-shaped slot 222, so that the movement trajectory of the pull rod 23 conforms to the rotation law of the connecting block 22, reduces unnecessary motion interference, and improves the overall collaborative motion effect of the equipment.
[0036] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various deformations and modifications to the above embodiment without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
