Description

Technical Field

[0001] This application belongs to the field of construction tools technology, specifically relating to a support device and measuring equipment. Background Technology

[0002] When renovating a house, there is often a need to measure in narrow spaces. Due to the limited size of these spaces, workers often cannot enter directly. Usually, measuring instruments, such as distance measuring instruments, are mounted on a support device, and then the whole structure consisting of the support device and the measuring instrument is placed in the narrow space to complete the collection of relevant parameters.

[0003] However, traditional support devices are not very convenient to use, which makes measurement operations difficult and inefficient. Utility Model Content

[0004] The purpose of this application is to provide a support device and a measuring device that can solve the problem of poor ease of use of support devices in related technologies.

[0005] In a first aspect, embodiments of this application provide a support device, including: The support mechanism includes a first guide member and a second guide member arranged at intervals along a first direction, and a first support member and a second support member arranged at intervals along a second direction, wherein the first direction intersects the second direction, and the first guide member and the second guide member are both supported on the first support member and the second support member. The mounting frame is at least partially located between the first guide and the second guide, and slides with both the first guide and the second guide in the second direction. The mounting frame is used to fit over the measuring instrument to drive the measuring instrument to move along the second direction. A drive mechanism is located at least partially between the first support member and the second support member and is connected to the mounting frame, and the drive mechanism is used to drive the mounting frame to slide along the second direction.

[0006] Secondly, this application discloses a measuring device, which includes a measuring instrument and the aforementioned support device, wherein the mounting frame of the support device is fitted over the measuring instrument.

[0007] Traditional support devices are difficult to adjust the position of the measuring instrument during actual use, resulting in poor ease of use.

[0008] In this embodiment, at least a portion of the driving mechanism is located between the first and second supports and connected to the mounting frame. The driving mechanism drives the mounting frame to slide along the second direction, and the mounting frame is fitted over the measuring device to move the measuring device along the second direction. With this configuration, the driving mechanism can automatically adjust the positions of the mounting frame and the measuring device in the second direction, thereby reducing the difficulty of adjusting the position of the measuring device in the second direction and improving the ease of use of the support device.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] The supporting device and measuring equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0014] Please refer to Figures 1 to 5 As shown in the embodiment of this application, a support device is provided, which includes a support mechanism 100, a mounting frame 200 and a drive mechanism 300.

[0015] The support mechanism 100 includes a first guide member 111 and a second guide member 112 arranged at intervals along a first direction, and a first support member 121 and a second support member 122 arranged at intervals along a second direction. The first direction intersects the second direction, and the first guide member 111 and the second guide member 112 are both supported on the first support member 121 and the second support member 122.

[0016] The first guide member 111, the second guide member 112, the first support member 121, and the second support member 122 are all, for example, horizontally arranged, and the first direction is, for example, perpendicular to the second direction. Specifically, the first direction is... Figure 2 The direction indicated by arrow A in the diagram, the second direction is... Figure 2 The direction indicated by arrow B in the diagram.

[0017] At least a portion of the mounting frame 200 is located between the first guide member 111 and the second guide member 112, and slides in cooperation with both the first guide member 111 and the second guide member 112 in the second direction. The mounting frame 200 is used to fit around the measuring device 500 so as to drive the measuring device 500 to move in the second direction.

[0018] Optionally, a portion of the mounting frame 200 is located between the first guide member 111 and the second guide member 112. The first guide member 111 and the second guide member 112 are symmetrically arranged on opposite sides of the mounting frame 200. Of course, the mounting frame 200 can also be located entirely between the first guide member 111 and the second guide member 112.

[0019] Optionally, the measuring device 500 is a rangefinder, used to measure parameters such as room dimensions, door and window dimensions, and wall flatness. More specifically, the measuring device 500 is a laser rangefinder. It should be noted that in this embodiment, there are no limitations on the type of measuring device 500 or the specific parameters measured by the measuring device 500; these are merely illustrative examples.

[0020] At least a portion of the drive mechanism 300 is located between the first support member 121 and the second support member 122 and is connected to the mounting frame 200, and the drive mechanism 300 is used to drive the mounting frame 200 to slide in a second direction.

[0021] Optionally, the drive mechanism 300 is only partially located between the first support member 121 and the second support member 122. Of course, the drive mechanism 300 may also be entirely located between the first support member 121 and the second support member 122. This application embodiment does not impose any restrictions on this.

[0022] Traditional support devices are difficult to adjust the position of the measuring instrument 500 during actual use, resulting in poor ease of use.

[0023] In this embodiment, at least a portion of the drive mechanism 300 is located between the first support member 121 and the second support member 122, and is connected to the mounting frame 200. The drive mechanism 300 drives the mounting frame 200 to slide along the second direction. The mounting frame 200 is fitted over the measuring device 500 to move the measuring device 500 along the second direction. With this configuration, the drive mechanism 300 can automatically adjust the positions of the mounting frame 200 and the measuring device 500 in the second direction, thereby reducing the difficulty of adjusting the position of the measuring device 500 in the second direction and improving the ease of use of the support device.

[0024] In actual use, the drive mechanism 300, for example, drives the mounting frame 200 to move horizontally, thereby adjusting the position of the support device after it has been installed in a narrow space. It should be noted that due to the limited size of narrow spaces, operators cannot directly enter. Typically, the support device is installed at the entrance of the narrow space, and then the drive mechanism 300 automatically adjusts the position of the measuring device 500, ensuring that the measuring device 500 is in its initial measuring position. It should also be pointed out that the support device is not limited to use in narrow spaces; narrow spaces are merely an example.

[0025] In one alternative embodiment, reference is made to... Figures 1 to 5 As shown, the mounting frame 200 is a shell structure. The two ends of the mounting frame 200 in the second direction are the first end and the second end, respectively. The first end of the mounting frame 200 is provided with a first opening 230, and the second end of the mounting frame 200 is provided with a second opening 240. Both the first opening 230 and the second opening 240 allow the measuring device 500 to enter and exit the internal space of the mounting frame 200. The first opening 230 is, for example, set opposite to the measuring end of the measuring device 500. In actual use, the measuring end of the measuring device 500 measures the target object through the first opening 230.

[0026] In other embodiments, the mounting frame 200 may also be a frame structure. It should be noted that the specific form of the mounting frame 200 is not limited in this embodiment of the application, and can be designed according to actual needs.

[0027] In another embodiment, the support device further includes a trigger 400, which is mounted on the support mechanism 100. The mounting frame 200 can be arranged opposite to or offset from the trigger 400. In other words, during the sliding of the mounting frame 200 along the second direction, the mounting frame 200 and the trigger 400 have two states: relative arrangement and offset. Specifically, Figure 1 The mounting frame 200 and the trigger element 400 are offset from each other. Figure 4 The mounting frame 200 is set relative to the trigger 400.

[0028] In the case where the mounting frame 200 and the trigger 400 are positioned opposite each other, the trigger 400 triggers the switch 520 of the measuring device 500 to switch the measuring device 500 to the start state.

[0029] In this embodiment, the drive mechanism 300 drives the mounting frame 200 to slide. When the mounting frame 200 slides to a position opposite to the trigger 400, the trigger 400 automatically triggers the switch 520 of the measuring device 500, thereby switching the measuring device 500 to the start state. In this configuration, the position of the trigger 400 is, for example, the initial measurement position. In this way, the measuring device 500 is only turned on when it is in the initial measurement position, thereby reducing errors and improving the measurement accuracy of the measuring device 500.

[0030] In other embodiments, the support device may not include the trigger 400. In this case, for example, it is necessary to switch the measuring device 500 to the start state first, and then move the measuring device 500 to the initial measurement position. That is, the measuring device 500 is already in the start state before it reaches the initial measurement position.

[0031] In another embodiment, reference Figure 3 and Figure 4As shown, the mounting frame 200 is provided with a receiving hole 221 for accommodating the switch 520. The trigger 400 is provided with a protrusion 410 on the side facing the support mechanism 100. When the receiving hole 221 and the protrusion 410 are arranged opposite to each other, the protrusion 410 extends into the receiving hole 221 and presses against the switch 520 so that the measuring device 500 switches to the start state.

[0032] In this embodiment, the trigger 400 mechanically presses against the switch 520 of the measuring device 500, thereby switching the measuring device 500 to the start state. This mechanical linkage design is not only simple in structure, but also low in cost.

[0033] Optionally, the shape of the receiving hole 221 is matched with the shape of the switch 520 to more accurately position the switch 520.

[0034] Further, refer to Figure 2 As shown, the mounting frame 200 has an opening 210, the measuring device 500 is located in the internal space of the mounting frame 200, the opening 210 is connected to the internal space of the measuring device 500, and the mounting frame 200 is hinged to a cover 220, which can be rotated to open and close the opening 210. The cover 220 has the receiving hole 221 mentioned above.

[0035] In actual use, before assembling the measuring device 500 into the internal space of the mounting frame 200, rotate the cover 220 so that the opening 210 is in the open state. After the measuring device 500 is assembled, rotate the cover 220 again so that the cover 220 covers the opening 210. At the same time, the switch 520 of the measuring device 500 is engaged in the receiving hole 221 to limit the switch 520 and reduce the shaking of the switch 520.

[0036] Further, refer to Figure 2 and Figure 4 As shown, the wall of the receiving hole 221 has a notch 2211. When the mounting frame 200 and the trigger 400 are offset from each other, the notch 2211 is set towards the protrusion 410. As the mounting frame 200 approaches the protrusion 410, the protrusion 410 enters the receiving hole 221 through the notch 2211 and contacts the switch 520 of the measuring device 500 to press the switch 520 of the measuring device 500, thereby causing the measuring device 500 to switch to the start state.

[0037] Specifically, refer to Figure 3 and Figure 4As shown, the protrusion 410 is fixedly disposed on the trigger 400. The measuring device 500 includes a measuring body 510 and a switch 520. At least a portion of the switch 520 protrudes from the outer surface of the measuring body 510. Under the pressing action of the protrusion 410, the switch 520 of the measuring device 500 retracts into the measuring body 510, thereby causing the measuring device 500 to switch to the start state.

[0038] In other embodiments, the trigger 400 may also trigger the switch 520 of the measuring device 500 in a non-contact manner. In this embodiment, the method by which the trigger 400 triggers the switch 520 of the measuring device 500 is not limited.

[0039] In another embodiment, reference Figure 3 and Figure 4 As shown, the trigger 400 is provided with a stop 420, which is located on the sliding path of the mounting frame 200. When the mounting frame 200 and the trigger 400 are arranged opposite each other, the stop 420 and the mounting frame 200 are engaged in a limit engagement in the second direction.

[0040] In this embodiment, with the mounting frame 200 and the trigger 400 positioned opposite each other, the stop 420 engages with the mounting frame 200 at the upper limit in the second direction. This allows the stop 420 to restrict the mounting frame 200 from continuing to approach the trigger 400 in the second direction, thereby limiting the mounting frame 200 and the measuring device 500 to a preset position. This facilitates precise positioning of the measuring device 500, which helps improve the measurement accuracy of the measuring device 500 and allows the measuring device 500 to remain relatively stably in the preset position.

[0041] In actual use, when the support device is placed in a narrow space, the operator cannot see the specific position of the mounting frame 200. By setting the stop part 420, the position of the mounting frame 200 can be controlled more precisely.

[0042] Optionally, the mounting frame 200 has a first end and a second end as described above, and a stop 420 is disposed toward the first end. The stop 420 is used to restrict the mounting frame 200 from sliding along the direction from its second end toward the first end. The direction from the second end of the mounting frame 200 toward the first end of the mounting frame 200 is, for example, Figure 1 The direction indicated by the arrow C in the diagram.

[0043] Optionally, the stop 420 is a stop plate.

[0044] In other embodiments, the trigger 400 may also omit the stop portion 420.

[0045] In another embodiment, reference Figure 1As shown, the trigger 400 is provided with a first limiting part 430 and a second limiting part 440. When the mounting frame 200 and the trigger 400 are arranged opposite each other, the first limiting part 430 and the second limiting part 440 are respectively located on opposite sides of the mounting frame 200 in the first direction, and both are engaged with the mounting frame 200 in the first direction.

[0046] In this embodiment, the mounting frame 200 is positioned opposite to the trigger 400, which means, for example, that the mounting frame 200 has moved to a preset position. In this state, the first limiting part 430 and the second limiting part 440 both cooperate with the mounting frame 200 in the first direction to limit the movement of the mounting frame 200 in the first direction, thereby keeping the mounting frame 200 stably in the preset position, which helps to improve the measurement accuracy of the measuring instrument 500.

[0047] Optionally, the first limiting part 430 and the second limiting part 440 are both limiting plates, for example, and the first limiting part 430 is connected to the second limiting part 440 through the stop part 420 mentioned above.

[0048] Optionally, the distance between the first limiting portion 430 and the second limiting portion 440 may be adapted to the dimension of the mounting frame 200 in the first direction to better position the mounting frame 200.

[0049] In other embodiments, the trigger 400 may also omit the first limiting part 430 and the second limiting part 440.

[0050] In another embodiment, reference Figures 1 to 5 As shown, the support mechanism 100 is provided with at least two plug-in structures 600, and each plug-in structure 600 is arranged at intervals along the second direction. The trigger member 400 is provided with a plug-in part 450, which can be selectively plugged into one of the plug-in structures 600.

[0051] When the plug-in part 450 is plugged into the plug-in structure 600, the position of the trigger 400 is fixed and stably maintained in the corresponding position. In this embodiment, at least two plug-in structures 600 are provided at intervals in the second direction, that is, in the sliding direction of the mounting frame 200. The plug-in part 450 can selectively plug into one of the plug-in structures 600. This means that the trigger 400 can be stably maintained in multiple different positions, and the position of the trigger 400 corresponds to the initial measurement position of the measuring device 500. In this way, the initial measurement position of the measuring device 500 can be flexibly adjusted to meet different measurement requirements.

[0052] Optionally, the distance between two adjacent plug-in structures 600 is equal, that is, the plug-in structures 600 are distributed at equal intervals. Of course, the distance between two adjacent plug-in structures 600 may also be unequal; this is just an example.

[0053] In other embodiments, the number of plug-in structures 600 may also be one.

[0054] In another embodiment, reference Figure 2 As shown, the plug-in structure 600 includes a first slot 610 and a second slot 620 disposed opposite to each other in a first direction. The first slot 610 is disposed on the first guide member 111, and the second slot 620 is disposed on the second guide member 112. The plug-in part 450 includes a first plug-in sub-part 451 and a second plug-in sub-part 452 disposed opposite to each other in a first direction. The first plug-in sub-part 451 is plugged into the first slot 610, and the second plug-in sub-part 452 is plugged into the second slot 620.

[0055] In this embodiment, both the first plug-in portion 451 and the second plug-in portion 452 are plugged into the support mechanism 100. This dual cooperation improves the reliability of the connection between the plug-in portion 450 and the support mechanism 100, thereby enhancing the stability of the trigger element 400. Furthermore, this arrangement allows the first plug-in portion 451 and the second plug-in portion 452 to share the load, preventing stress concentration and extending the service life of the plug-in portion 450.

[0056] Optionally, both the first plug-in sub-part 451 and the second plug-in sub-part 452 are plug-in posts, and the first plug-in sub-part 451 and the second plug-in sub-part 452 are arranged symmetrically.

[0057] Optionally, refer to Figure 2 As shown, the top surface of the first guide member 111 is provided with a first slot 610, and the top surface of the second guide member 112 is provided with a second slot 620.

[0058] In other embodiments, the plug portion 450 may include only the first plug sub-port 451, and correspondingly the plug structure 600 may include only the first slot 610; or, the plug portion 450 may include only the second plug sub-port 452, and correspondingly the plug structure 600 may include only the second slot 620.

[0059] In another embodiment, reference Figure 2 As shown, the support mechanism 100 is provided with a scale line group 700, which includes at least two scale lines. The scale lines are arranged at intervals along the second direction, and different plug-in structures 600 correspond to different scale lines.

[0060] In this embodiment, different plug-in structures 600 correspond to different scale lines. In this way, without the need for additional tools, operators can determine the position of different plug-in structures 600 by observing the scale lines. This setting makes it easy for operators to quickly find the corresponding plug-in structure 600.

[0061] It should be noted that the specific number of scale lines included in the scale line group 700 depends on the actual situation, and the scale lines in the same scale line group 700 can be set at equal intervals or at unequal intervals. In this embodiment, there is no limitation on this.

[0062] In other embodiments, the support mechanism 100 may also omit the scale line group 700.

[0063] In another embodiment, at least one of the first guide member 111 and the second guide member 112 is provided with a scale line group 700. In this arrangement, there is no need to add other components to lay out the scale line group 700, as the scale line group 700 is directly laid out on the first guide member 111 and the second guide member 112, which simplifies the structure of the support device.

[0064] Optionally, to improve the ease of use of the support device, the first guide 111 and the second guide 112 are provided with scale line group 700, for example.

[0065] In other embodiments, the support device may also be additionally provided with other components besides the first guide 111 and the second guide 112 to set the scale line group 700.

[0066] In another embodiment, reference Figure 2 and Figure 3 As shown, the support device also includes a lifting mechanism 810. The support mechanism 100 is supported by the lifting mechanism 810. The lifting mechanism 810 is used to drive the support mechanism 100 to move up and down along a third direction. The third direction intersects with both the first and second directions.

[0067] In this embodiment, the lifting mechanism 810 can drive the support mechanism 100 to rise and fall, so that the height of the support mechanism 100 can be freely adjusted to meet different measurement needs.

[0068] Optionally, the third direction is perpendicular to both the first and second directions, and is a vertical direction. The lifting mechanism 810 is used to drive the support mechanism 100 to move vertically. Specifically, the third direction is... Figure 1 The direction indicated by the arrow line D in the diagram.

[0069] In other embodiments, the support device may also exclude the lifting mechanism 810.

[0070] In another embodiment, both the first guide member 111 and the second guide member 112 extend along a second direction. Both ends of the first guide member 111 and the second guide member 112 in the second direction are respectively supported on the first support member 121 and the second support member 122. Both the first support member 121 and the second support member 122 extend along a first direction. Both ends of the first support member 121 and the second support member 122 in the first direction support the lifting mechanism 810. The first guide member 111, the second guide member 112, the first support member 121, and the second support member 122 are, for example, strip-shaped structures. In this configuration, the layout of the lifting mechanism 810 is more reasonable, which can prevent local stress concentration in the support mechanism 100, help extend the service life of the support mechanism 100, and improve the stability of the support mechanism 100.

[0071] Optionally, refer to Figures 1 to 3 As shown, in the first direction, both ends of the first support member 121 and both ends of the second support member 122 are provided with support protrusions 123. The support protrusions 123 are located below the first support member 121 or the second support member 122 and extend along the third direction. The first support member 121 and the second support member 122 are both connected to the lifting mechanism 810 through the support protrusions 123.

[0072] Optionally, the support mechanism 100 may include only the first guide 111, the second guide 112, the first support 121, and the second support 122 to simplify the structure of the support mechanism 100.

[0073] Optionally, the two opposite sidewalls of the mounting frame 200 contact the first guide 111 and the second guide 112 respectively, so as to achieve a sliding fit between the mounting frame 200 and the first guide 111 and the second guide 112 in the second direction.

[0074] Optionally, refer to Figures 1 to 3 As shown, the lifting mechanism 810 is an electrically telescopic mechanism, and for example, each of the electric telescopic mechanisms corresponds one-to-one with the support column 820. At least a portion of the electric telescopic mechanism is located within the support column 820 to reduce external influences on the electric telescopic mechanism. The telescopic end of the electric telescopic mechanism is connected to the support protrusion 123 mentioned above, and the support column 820 is supported on the corresponding support base, for example, by an anti-slip pad 830. The anti-slip pad 830 can increase the friction between the support column 820 and the support base, thereby improving the stability of the support column 820.

[0075] In other embodiments, at least one of the two ends of the first support member 121 in the first direction and the two ends of the second support member 122 in the first direction may not be provided with a lifting mechanism 810.

[0076] In another embodiment, reference Figure 1 and Figure 5 As shown, the drive mechanism 300 includes a drive source 310 and a screw 320. Part of the screw 320 is located between the first support member 121 and the second support member 122 and is threadedly engaged with the mounting frame 200. The two ends of the screw 320 are rotatably mounted on the first support member 121 and the second support member 122, respectively. The drive source 310 is connected to the screw 320 and is used to drive the screw 320 to rotate.

[0077] In this embodiment, the screw 320 is threadedly engaged with the mounting frame 200, thereby driving the mounting frame 200 to move along the second direction. The threaded engagement method has good reliability and high engagement accuracy, thereby improving the smoothness of the sliding of the mounting frame 200 and facilitating precise control of the position of the mounting frame 200.

[0078] Optionally, the drive source 310 is fixed to the first support member 121 or the second support member 122. The drive source 310 is a motor. The mounting frame 200 is provided with a threaded sleeve 250, which is sleeved on the screw 320 and threadedly engaged with the screw 320. Specifically, the threaded sleeve 250 is provided, for example, at the bottom end of the mounting frame 200.
