Description

Technical Field

[0001] The utility model relates to the technical field related to construction, in particular to a shock-absorbing bracket for a laser level. Background Art

[0002] In indoor and outdoor decoration projects, it is often necessary to obtain a horizontal or vertical reference line. The laser level is an indispensable measuring instrument at this time, which can emit horizontal and vertical laser beams. The function of the laser level bracket is to adjust the effective height of the laser projected by the laser level and provide support for the laser level to maintain levelness.

[0003] In actual construction, vertical transportation of concrete between floors, drilling of holes in walls and slabs by electric drills, and other construction activities often cause the floor to vibrate, which seriously affects the accuracy of the laser level measurement. Often, the measurement can only be continued after the vibration disappears.

[0004] Therefore, the existing bracket for the laser level is provided with a shock-absorbing structure, but since the height of the laser level needs to be adjusted according to different usage requirements when in use, when the placement height of the laser level changes, the center of gravity also changes accordingly, and the existing shock-absorbing structure is fixed, and when the placement height of the laser level changes, the shock-absorbing effect is relatively general.

DETAILED DESCRIPTION

[0033] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0034] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0035] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0036] The utility model aims to propose a bracket structure for supporting a laser level, which has a certain shock-absorbing effect, thereby improving the stability of the laser level during use. The specific implementation method is as follows:

[0037] See also Figure 1 to Figure 6 In an embodiment of the utility model, a shock-absorbing bracket for a laser level includes a mounting platform 1 and a triangular bracket installed at the bottom of the mounting platform 1, a buffer box 2 is arranged on the side of the mounting platform 1 away from the triangular bracket; and an adjusting disk 3 is also included, a receiving platform 4 is arranged on one side of the adjusting disk 3, and the other side is connected to a buffer unit arranged in the buffer box 2, and the receiving platform 4 is connected to the adjusting unit arranged in the adjusting disk 3, wherein: the buffer unit includes a receiving disk 17 and a movable disk 18 arranged in the buffer box 2, an elastic member is arranged between the receiving disk 17 and the movable disk 18, and the movable disk 18 is connected to the adjusting unit, and when the adjusting unit moves, the distance between the receiving platform 4 and the adjusting disk 3 can be adjusted, and the elastic force of the elastic member can be changed at the same time.

[0038] In this embodiment, the tripod bracket is unfolded and placed on the ground or floor, and then the laser level is connected to the mounting base 11 installed on the receiving platform 4, and then the adjustment unit is controlled to adjust the laser level on the receiving platform 4 to the desired height. When the laser level is raised, the adjustment unit synchronously adjusts the elastic force of the elastic member to increase the elastic force of the elastic member, ensuring that when the center of gravity of the laser level changes, the buffering force of the buffer unit follows the change, thereby ensuring the shock absorbing effect of the laser level at different heights, so that the laser level maintains normal operation.

[0039] Specifically, the elastic member includes a plurality of rubber seats 20 respectively installed on the receiving plate 17 and the movable plate 18, and a spring 21 is arranged between two opposite rubber seats 20. Preferably, the spring 21 described in this embodiment can also be replaced by an elastic telescopic rod, and the rubber seat 20 and the spring 21 cooperate with each other to absorb vibration impact, convert the impact force into mechanical energy, and thus achieve a shock absorption effect.

[0040] It should be noted that the plurality of rubber seats 20 are equidistantly arranged in the circumferential direction, so as to ensure that the force between the receiving plate 17 and the movable plate 18 is balanced.

[0041] As an embodiment of the present invention, please refer to Figure 2-Figure 6 The adjusting unit includes a rotating shaft 26 rotatably installed in the adjusting disk 3, and both ends of the rotating shaft 26 pass through the adjusting disk 3 and are respectively fixed with a first threaded rod 13 and a connecting shaft 23; the first threaded rod 13 is threadedly connected to a threaded sleeve 16 fixed on the receiving platform 4, and the connecting shaft 23 is inserted into a second threaded rod 19 rotating in the buffer box 2 and is slidably connected to the second threaded rod 19, the second threaded rod 19 passes through the movable disk 18 and is threadedly connected to the movable disk 18, preferably, a cylindrical cavity is formed on the second threaded rod 19 for inserting the connecting shaft 23; at least one strip-shaped limiting groove 25 is formed on the inner wall of the cylindrical cavity, and a strip-shaped limiting slider 24 slidably matched with the strip-shaped limiting groove 25 is formed on the connecting shaft 23.

[0042] In this embodiment, when the rotating shaft 26 rotates, it drives the first threaded rod 13 and the connecting shaft 23 to rotate synchronously. The first threaded rod 13 drives the receiving platform 4 to move axially along the first threaded rod 13 through the action of the threaded sleeve 16, thereby adjusting the distance between the receiving platform 4 and the mounting platform 1 to achieve height adjustment of the laser level. At the same time, when the connecting shaft 23 rotates, it drives the second threaded rod 19 to rotate. When the second threaded rod 19 rotates, it drives the movable disk 18 to move axially of the smoke, thereby changing the distance between the movable disk 18 and the receiving disk 17, achieving squeezing or relaxation of the elastic member to change the deformation of the elastic member. The above-mentioned mechanical coordination is used to achieve synchronous adjustment of the height of the laser level and the deformation of the elastic member.

[0043] It should be noted that a through groove for the connection shaft 23 to move is formed on the receiving plate 17 and the buffer box 2 , and the connection shaft 23 does not contact the receiving plate 17 and the buffer box 2 .

[0044] For further information, see Figure 2-Figure 6 The adjustment unit also includes a transmission rod 27 rotatably mounted on the buffer box 2, one end of the transmission rod 27 extends into the buffer box 2 and is rotatably connected to the rotating shaft 26 through the bevel gear set 14, and the other end is fixed with a knob 5. Of course, the knob 5 can be replaced by a crank, as long as it can drive the transmission rod 27 to rotate. The rotation of the transmission rod 27 drives the bevel gear set 14 to rotate, and the bevel gear set 14 drives the rotating shaft 26 to rotate, thereby realizing the adjustment requirements.

[0045] In order to eliminate the rotation of the receiving platform 4 relative to the adjusting disk 3, at least three groups of telescopic rods 15 are installed between the adjusting disk 3 and the receiving platform 4, wherein the telescopic rod 15 includes a fixed sleeve and a movable column, the fixed sleeve and the movable column are respectively fixed on the adjusting disk 3 and the receiving platform 4, and the movable column is inserted into the fixed sleeve and can slide axially relative to the fixed sleeve.

[0046] In order to realize the connection between the threaded sleeve 16 and the receiving platform 4, at least three support rods 12 are fixed between the threaded sleeve 16 and the receiving platform 4. The support rods 12 are arranged at an angle. The arrangement of the support rods 12 can increase the space between the receiving platform 4 and the adjusting disk 3 on the one hand, and increase the connection stability of the receiving platform 4 on the other hand.

[0047] See also Figure 1 The above-mentioned tripod bracket includes: three legs 6 hinged on the mounting platform 1 and a vertical rod 9 fixed on the mounting platform 1 and located in the middle of the three legs 6; a movable sleeve 10 is slidably installed on the vertical rod 9, a connecting rod 7 is hinged on the movable sleeve 10, and one end of the connecting rod 7 away from the movable sleeve 10 is hinged to the leg 6; a rubber foot 8 is installed on one end of the leg 6 away from the mounting platform 1.

[0048] The rubber feet 8 can increase the friction between the legs 6 and the ground on the one hand, and can play a preliminary shock-absorbing role on the other hand. The connection between the legs 6 and the uprights 9 in this embodiment belongs to the application of the prior art, so this embodiment will not be described in detail.

[0049] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
