Description

Technical Field

[0001] The invention relates to the technical field of decoration, in particular to a house measuring device for decoration. Background Art

[0002] Decoration refers to the activity of remodeling and decorating the interior of a house, which covers the renovation and decoration of walls, floors, windows and doors. The purpose of decoration is to meet the needs and personalization of the residents for the practicality and aesthetics of the house. Before decoration, it is necessary to accurately obtain the size of the house, and a house measuring device for decoration will be used.

[0003] House measuring devices, also known as house measuring instruments and house measuring equipment, are devices used to measure parameters such as house size, structure and spatial layout. They include scanning measuring instruments. Scanning measuring instruments are instruments used to measure the three-dimensional spatial dimensions of objects. Laser scanning technology is usually used. It emits a laser beam to scan the surface of the object, and then the receiver records the light signal reflected by the laser beam to obtain the three-dimensional coordinate information of the object surface. Through this information, the laser scanning measuring instrument can accurately measure the size, shape, position and other parameters of the object. Scanning measuring instruments are usually used in conjunction with tripod brackets, but the automatically rotating bracket is expensive, and the user needs to manually and slowly rotate the scanning measuring instrument when marking special-shaped positions. The user rotates with one hand and operates the computer connected to the scanning measuring instrument with the other hand, which increases the difficulty of operation for the user. During rotation, the user's hand is easily affected by the downward gravity, which causes the laser scanner to shake and lose its level, resulting in inaccurate measurement results and reduced use effect.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing house measuring devices on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0046] The specific implementation of this embodiment is as follows: before decoration, the user needs to use a scanning measuring instrument to obtain the three-dimensional parameters of the house. The user places the measuring instrument body 1 on the top of the support block 3101, and embeds the clamping column 3102 into the inner wall of the measuring instrument body 1. The small protrusion on the surface of the clamping column 3102 can limit the rotation of the measuring instrument body 1, thereby avoiding rotation between the measuring instrument body 1 and the clamping column 3102. When the clamping column 3102 is embedded in the inner wall of the measuring instrument body 1, the three positioning feet 11 are all embedded in the inner wall of the support block 3101 and penetrate to the bottom of the support block 3101, thereby realizing the stable placement of the measuring instrument body 1, completely avoiding the occurrence of the self-rotation of the measuring instrument body 1, and increasing the stability of the measuring instrument body 1 during operation. The user places the support assembly 2 on the ground to achieve vertical support for the measuring instrument body 1. The measuring instrument body 1 is then required to rotate 360 ​​degrees to obtain panoramic parameters of the room. The user slowly applies a pedal force to one end of the foot pedal 3109 with his foot. The two support bars 3108 are located in the middle of the foot pedal 3109. One end of the foot pedal 3109 sinks. Due to the lever principle, the other end of the foot pedal 3109 rises. The foot pedal 3109 is configured to be telescopic, which avoids the situation where the sliding column 3110 is laterally displaced and stuck when the foot pedal 3109 rotates. The rise of the foot pedal 3109 drives the sliding column 3110 to move in the guide The inner wall of the guide frame 3111 moves upward, and the upward movement of the sliding column 3110 pushes the connecting block 3112 to move upward. The upward movement of the connecting block 3112 drives the connecting column 3113 to move upward on the inner wall of the guide frame 3111. The upward movement of the connecting column 3113 drives one end of the lever bar 3114 to move upward. The lever bar 3114 adopts a telescopic type at both ends, which also avoids the situation of being stuck during rotation. Due to the cooperation of the connecting plate 3115 and the connecting rod 3116, the lever bar 3114 forms a lever structure, so that the rise of one end of the lever bar 3114 causes the other end of the lever bar 3114 to sink, and the sinking of one end of the lever bar 3114 drives the mounting block 3117 to move downward, and the downward movement of the mounting block 3117 The sleeve 3104 is driven to move vertically downward, and the downward movement of the sleeve 3104 drives the guide column 3105 to move vertically downward on the surface of the rotating rod 3103. Because the guide column 3105 is embedded in the inner cavity of the linear groove 3106 and slides, when the guide column 3105 moves vertically, the special shape of the linear groove 3106 causes the rotating rod 3103 to generate a rotational force. When the user steps on the foot pedal 3109, the first damping telescopic rod 3118 and the spring 3119 at the bottom are compressed until the user can no longer step on it. At this time, the rotating rod 3103 completes a half circle of rotation through the stepping of the foot pedal 3109. At this time, the user releases the stepping on the foot pedal 3109, and the first damping telescopic rod 3118 and the spring 3119 are compressed.

[0047] The coordinated action causes the foot pedal 3109 to slowly reset. The slow reset of the foot pedal 3109 causes the other end of the foot pedal to move downward, thereby driving the sliding column 3110, the connecting block 3112 and the connecting column 3113 to move downward, thereby driving one end of the lever bar 3114 to sink, causing the other end of the lever bar 3114 to move upward. The upward movement of the other end of the lever bar 3114 drives the mounting block 3117 and the sleeve 3104 to move upward. The upward movement of the sleeve 3104 drives the guide column 3105 to move upward, and cooperates with the linear groove 3106 to complete the continued rotation of the rotating rod 3103, realize the rotation of the support block 3101 and the clamping column 3102, thereby realizing a 360-degree rotation of the measuring instrument body 1. The setting of the first damping telescopic rod 3118 can add resistance to the user's footstep force, increase the balance of the pedal force, and thus make the rotation speed of the rotating rod 3103 more uniform.

By setting the limiting groove 3209 and the limiting block 3210, the limiting groove 3209 and the limiting block 3210 are embedded in each other, so as to limit the vertical moving distance of the limiting block 3210 in the inner cavity of the limiting groove 3209, thereby preventing the limiting block 3210 from detaching from the inner cavity of the limiting groove 3209, thereby preventing the sliding rod 3203 from moving out of the inner cavity of the linear groove 3205, thereby increasing the stability of the sliding column 3110 during movement.

[0053] The specific implementation of this embodiment is as follows: after the user places the measuring instrument body 1 on the top of the support tube 22, the three positioning feet 11 of the measuring instrument body 1 are embedded in the inner wall of the support block 3101 and penetrate to the bottom of the support block 3101. The user rotates the handle 3206, and the rotation of the handle 3206 drives the turntable 3201 to rotate. The rotation of the turntable 3201 causes the arc hole 3202 to rotate. The rotation of the arc hole 3202 drives the sliding rod 3203 in the linear groove 3205, so that the sliding rod 3203 203 moves linearly along the inner cavity of the linear groove 3205, thereby driving the clamping block 3204 to move linearly until the inner sides of the three clamping blocks 3204 are in close contact with the surfaces of the three positioning feet 11. The contact surfaces of the clamping blocks 3204 and the positioning feet 11 are provided with anti-slip pads, which increase the friction between the clamping blocks 3204 and the positioning feet 11, realize lateral support for the positioning feet 11, reduce the possibility of sliding of the positioning feet 11, and thus increase the stability of the measuring instrument body 1 placed on the top of the support block 3101.

[0054] Embodiment 3

[0055] See also Figure 1-12The present invention provides a technical solution: a house measuring device for decoration. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The rotating mechanism 3 also includes a limit unit 33, which is arranged at the bottom of the measuring instrument body 1 and is used to limit the moving trajectory of the pedal drive unit 31 to ensure the stability of the rotation direction of the measuring instrument body 1.

[0056] As a further limitation of the rotating mechanism 3 of the present invention, the limiting unit 33 includes a receiving groove 3301, which is opened on the inner wall of the rotating rod 3103, and the inner cavity of the receiving groove 3301 is provided with a group plate 3302, and one side of the group plate 3302 is fixedly connected with a pressing rod 3303 and a limiting rod 3304, the surface of the pressing rod 3303 and the surface of the limiting rod 3304 are both slidably connected to the inner wall of the rotating rod 3103, one end of the pressing rod 3303 and one end of the limiting rod 3304 are both inserted into the inner cavity of the linear groove 3106, and an elastic ring 3305 is fixedly connected to the inner side of the receiving groove 3301, and one end of the elastic ring 3305 is fixedly connected to one side of the group plate 3302.

[0057] A guide rod 3306 is fixedly connected to the inner side of the storage groove 3301, and the inner wall of the assembly plate 3302 is slidably connected to the surface of the guide rod 3306. The elastic ring 3305 is sleeved on the surface of the guide rod 3306. By setting the guide rod 3306, the moving trajectory of the assembly plate 3302 is guided, and the left and right shaking of the assembly plate 3302 is limited by the embedded contact between the surface of the guide rod 3306 and the inner wall of the assembly plate 3302, which increases the stability of the assembly plate 3302 during movement, avoids lateral deformation of the elastic ring 3305, and extends the service life of the elastic ring 3305.

[0058] The specific implementation of this embodiment is as follows: when the guide post 3105 slides in the inner cavity of the linear groove 3106, due to the shape of the linear groove 3106 having two pointed ends, when the guide post 3105 moves to the pointed end, it is easy to produce divergence in the moving direction, and there is a possibility of moving back. This situation can be avoided by the limit unit 33. When the guide post 3105 is about to move to the pointed end, the guide post 3105 squeezes the pressing rod 3303. The end of the pressing rod 3303 extending to the inner cavity of the linear groove 3106 is beveled, so that during the sliding process of the guide post 3105, the pressing rod 3303 is gradually compressed into the inner cavity of the storage groove 3301. The contraction of the pressing rod 3303 drives the assembly plate 3302 to move, and the movement of the assembly plate 3302 has an impact on the inner cavity of the storage groove 3301. When the guide rod 3306 is in the process of sliding, the surface of the guide rod 3306 is disconnected from the pressing rod 3303 and one end of the limiting rod 3304, thereby canceling the squeezing of the pressing rod 3303 and the limiting rod 3304. At this time, the reaction force of the spring 3119 drives the assembly plate 3302, the pressing rod 3303 and the limiting rod 3304 to reset and re-extend to the inner cavity of the linear groove 3106. At this time, the limiting rod 3304 blocks the possibility of the guide column 3105 returning, thereby realizing the smooth rotation of the rotating rod 3103.
