Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a digital display angle level that can be used against a wall. Background Art

[0002] A level is mainly used to detect or measure horizontal and verticality, and is widely used in construction and decoration projects. With the development of the level, its functions are becoming more and more diverse. For example, it is designed into two rotatable parts to realize the function of measuring other angles. However, when measuring an angle with the existing level, it is usually necessary to hold one part with one hand and press it tightly against the wall, and rotate the other part with the other hand to measure the angle.

[0003] However, manual control is prone to instability and may accidentally shift, resulting in inaccurate measurement and the need for re-measurement, which affects the measurement efficiency. If the shift is small, it may even go unnoticed, affecting the measurement accuracy. And after the level is rotated multiple times, it is easy to become loose, so that after the level is rotated to the required position, it may automatically rotate downward due to its own weight, affecting the measurement accuracy. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies of the prior art, and provide a digital display angle level that can be used against a wall. By setting a waterproof rubber strip, it can be used against the wall to avoid measurement errors caused by manual support. By setting a hinge structure and a positioning clip, the rotation of the angle scale has a certain damping and can be fixed after rotation, avoiding the angle scale from rotating downward due to its own weight and further improving the measurement accuracy.

[0005] To solve the above problems, the utility model adopts the following scheme:

[0006] A digital display angle level that can be used against a wall, comprising a level main body, an angle scale, a hinge structure for hinging one end of the angle scale to the level main body, and a display screen capable of displaying the rotation angle of the angle scale. End cover assemblies are connected to both ends of the level main body, and a waterproof rubber strip capable of sticking to the wall is bonded to the side wall of the end cover assembly. The waterproof rubber strip and the angle scale are on the same side of the level main body.

[0007] In the above scheme, the waterproof rubber strip is pasted on the wall where the angle needs to be measured. The angle scale is rotated through the hinge structure, and the rotation angle is displayed through the display screen to realize angle measurement. The waterproof rubber strip and the angle scale are on the same side of the level main body, so that when the level is used against the wall, the angle scale is closer to the wall, which is convenient for observation and the angle measurement is more accurate.

[0008] Preferably, the end cover assembly includes a separable first part and a second part, and an elastic member is provided between the first part and the second part.

[0009] Pull the first part to separate the first part from the second part, thereby driving the spirit level body away from the wall surface, expanding the space between the spirit level body and the wall surface, facilitating the rotation of the angle ruler, and making the first part recover and fit with the second part again through the elastic member.

[0010] Preferably, the hinge structure includes a damping disc provided with a plurality of tooth grooves, at least one rack engaged with the tooth grooves, the rack is connected to the spirit level body, the damping disc is further provided with a clamping block, and the angle ruler is provided with a clamping groove capable of being engaged with the clamping block. The damping disc and the angle ruler are connected by the engagement of the clamping block and the clamping groove.

[0011] In the above setting, when rotating the angle ruler, the angle ruler drives the damping disc to rotate through the engaged clamping groove and the clamping block, and the damping disc rotates along with the engaged rack tooth grooves, so that the rotation of the angle ruler is a gear rotation, which has a certain damping characteristic. Therefore, the angle ruler is not easy to loosen, avoiding the angle ruler from automatically rotating downwards due to its own weight and ensuring the measurement accuracy.

[0012] Preferably, both the angle ruler and the damping disc are provided with connection holes, the two connection holes are coaxially arranged and inserted with a hinge shaft, and the hinge shaft is provided with a semi-circular groove, and a positioning clamping member capable of fixing the angle ruler after rotation is connected in the semi-circular groove.

[0013] Preferably, the positioning clamping member is provided with a clamping portion capable of clamping on the end face of the angle ruler.

[0014] In the above setting, when the angle ruler is rotated to the required position, then drive the hinge shaft to rotate through the positioning clamping member, so that the clamping portion clamps on the end face of the angle ruler to fix the angle ruler and prevent it from automatically rotating downwards due to its own weight.

[0015] Preferably, the length of the angle ruler is less than the length of the spirit level body. A slide rail is provided on one side of the spirit level body away from the hinge structure, and a fixed clamping member is slidably connected in the slide rail. A positioning groove capable of being engaged with the fixed clamping member is provided on the other side of the angle ruler away from the hinge structure.

[0016] In the above setting, when the spirit level is no longer in use, the angle ruler can be rotated to the horizontal state, and the fixed clamping member is slid to make it snap into the positioning groove, thereby fixing the angle ruler, preventing it from rotating randomly due to external reasons when not in use and loosening the hinge structure, and at the same time facilitating storage.

[0017] Preferably, the slide rail extends through the entire spirit level body along its length.

[0018] Extending the slide rail can be used to install other accessories or auxiliary devices, increasing the functionality of the spirit level body.

[0019] Preferably, the positioning groove extends through the entire angle ruler along its length.

[0020] An extended positioning groove can be used to install other accessories or auxiliary devices, increasing the functionality of the angle ruler.

[0021] Preferably, the spirit level main body is provided with bubble indicating columns, including a horizontal bubble indicating column for detecting whether it is horizontal and a vertical bubble indicating column for detecting whether it is vertical.

[0022] The above settings are to achieve the functions of detecting horizontal and vertical of the spirit level.

[0023] Preferably, observation holes are provided at the positions corresponding to the bubble indicating columns on the angle ruler.

[0024] The observation holes are provided to enable the observation of the bubble indicating columns even from one side of the angle ruler.

[0025] The beneficial effects of the present utility model are as follows:

[0026] By providing an adhesive waterproof rubber strip, the present utility model can be pasted on the wall for measurement, thus fixing the position of the spirit level main body, avoiding measurement errors that may be caused by manually holding the measurement, and improving the measurement accuracy and measurement efficiency.

[0027] The articulated structure provided by the present utility model enables the rotation of the angle ruler to have a certain damping characteristic, avoiding the angle ruler from automatically turning down due to its own weight when rotating and fixing the positioning clip. The further fixing of the positioning clip also avoids the automatic downward rotation of the angle ruler, thus further improving the measurement accuracy. Description of the Drawings

[0038] Both ends of the spirit level main body 01 are also connected with end cap assemblies 06. A waterproof rubber strip 07 capable of being pasted on the wall surface is bonded to the side wall of the end cap assembly 06. The waterproof rubber strip 07 is made of a high-strength and reusable material such as silicone with a special formula, which not only ensures the bonding strength with the wall surface, but also facilitates cleaning and multiple uses. The waterproof rubber strip 07 and the angle ruler 02 are located on the same side of the spirit level main body 01. The end cap assembly 06 includes a separable first part 061 and a second part 062, and an elastic member 063 is arranged between the first part 061 and the second part 062.

[0039] Paste the spirit level main body 01 on the wall surface where the angle needs to be measured through the waterproof rubber strip 07. Rotate the angle ruler 02 through the hinge structure 03, and display the rotation angle through the display screen 05 to realize angle measurement; if the space between the spirit level main body 01 and the wall surface is too small and it is not easy to operate the angle ruler 02, then pull the first part 061 to separate the first part 061 and the second part 062, thereby driving the spirit level main body 01 away from the wall surface, expanding the space between the spirit level main body 01 and the wall surface, facilitating the rotation of the angle ruler 02, and then let go. Through the elastic member 063, the first part 061 and the second part 062 are re-fitted.

[0040] The hinge structure 03 includes a damping disc 031 provided with a plurality of tooth grooves 0311, four racks 032 evenly distributed along the circumferential direction and meshing with the tooth grooves 0311. The racks 032 are arranged in an installation housing 14, and the installation housing 14 is connected with the spirit level main body 01.
