Description

Technical Field

[0001] This invention belongs to the field of masonry construction technology in building engineering, and specifically relates to an adjustable laser counting rod. Background Technology

[0002] The bricklaying gauge, an indispensable tool in masonry construction, has been used to this day. However, both the earliest and later improved telescopic gauges remain inconvenient to carry and use, requiring the assistance of nylon thread to complete the work. Furthermore, for complex and demanding masonry projects, traditional gauges are ineffective, sometimes sacrificing quantity for quality, thus reducing efficiency and failing to meet the demand for a balance between quality and quantity. In addition, existing gauges struggle to control mortar joint thickness using a thread; when the masonry wall is long, the thread sags, affecting the thickness and accuracy of the masonry. The nylon thread is also prone to breakage during construction, impacting progress. While the patent "An Automatic Adjustment Gauge and Measurement Method (CN110306812A)" discloses an automatic adjustment method using a motor and gear structure, this method has a slow lifting speed. For applications with large vertical spans, the slow operation hinders progress, and the accuracy of the positioning line is difficult to control. Summary of the Invention

[0003] To address the shortcomings of existing bricklaying gauges, which often require nylon thread for masonry work and are ineffective for complex and demanding projects, failing to meet both quality and quantity requirements, and which make it difficult to control mortar joint thickness via thread, with the thread sagging when the masonry wall is long, affecting the thickness and accuracy of the masonry, and the nylon thread is also prone to breakage during construction, impacting the construction progress, this invention provides an adjustable laser bricklaying gauge.

[0004] The solution adopted by this invention to solve its technical problem is as follows: an adjustable laser pointer, including a pole, a laser pointer assembly, a support mechanism, and a lifting adjustment assembly. The pole is axially fitted onto the support mechanism, and the laser pointer assembly is vertically fixed to the pole in the horizontal direction. The support mechanism is provided with an auxiliary rod and a gear. The auxiliary rod is parallel to the pole and is supported and fixed at different positions when the pole moves up and down by a diagonal brace installed on the auxiliary rod. A rack is laid axially on one side of the pole, and the rack meshes with the gear on the support mechanism. In its natural state, the rack moves the pole up and down by rotating the gear, thereby achieving fine adjustment of the laser pointer position. The lifting adjustment assembly includes a composite clamp, which is fitted onto the auxiliary rod. Its front side is clamped and fixed to the pole and the rack. Adjusting the composite clamp allows for adjustment of the pole's height and for the rack to engage and disengage with the pole.

[0005] As a preferred embodiment of the present invention, the support mechanism includes a tripod and a support platform fixedly installed at the top of the tripod. The auxiliary rod is fixed axially on the support platform, and the upright rod passes through the support platform and extends downward to be fitted into the tripod sleeve at the bottom of the tripod.

[0006] As a preferred embodiment of the present invention, a bubble level is installed on the support platform to ensure the levelness of the support platform on the tripod.

[0007] As a preferred embodiment of the present invention, the composite clamp includes a main clamp and an auxiliary clamp. The main clamp is fitted onto the auxiliary rod, and the other side is connected to the auxiliary clamp via a main-auxiliary clamp pivot. The main clamp is clamped to the upright rod by main pressure blocks symmetrically installed on the main clamp, and the rack and upright rod are clamped by auxiliary pressure blocks symmetrically installed on the auxiliary clamp.

[0008] As a preferred embodiment of the present invention, spring pieces are symmetrically fixed on both sides of the rack by rivets, and the spring pieces and the rack are slidably connected by a concave-convex connection structure.

[0009] As a preferred embodiment of the present invention, the laser pointer assembly includes a laser pointer and a slot, the slot being fixedly mounted on a pole in a horizontal direction, and the laser pointer being fitted into the slot.

[0010] As a preferred embodiment of the present invention, the upright is provided with a scale.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention adjusts the height of the upright by matching and fixing a composite clamp to the upright. Through the meshing of gears and a rack and pinion, the height of the upright can be adjusted by single-handed operation of the auxiliary and main clamps. Furthermore, in addition to coarse adjustments, the precise position of the laser pointer can be adjusted by rotating the handle on the gear, thereby enabling more accurate control of the laser pointer's position. This invention also uses an auxiliary rod fixed to the support platform. This rod matches and fits with the main clamp on the composite clamp, limiting the position of the composite clamp and ensuring that it remains horizontal during vertical movement, further constraining the upright. Additionally, it works with the diagonal brace to support and fix the upright in the set position. This invention has a simple structure and is easy to operate, allowing for single-handed adjustment of the upright's position. It has a wide range of applications, suitable for various complex masonry constructions, reducing environmental limitations on construction. Moreover, this invention provides more precise control of the lines, further improving construction accuracy. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please see Figure 1-5 This invention provides an adjustable laser bricklaying gauge to solve the problems of existing bricklaying gauges, such as difficulty in controlling the mortar joint thickness by means of a wire, the wire sagging when the masonry wall is long, which affects the thickness of the masonry and the accuracy of bricklaying, and the nylon wire being prone to breakage during the masonry process, which affects the construction progress.

[0016] Example 1: The adjustable laser pointer pole provided by this invention includes a pole 2, a laser pointer assembly 3, a support assembly, and a lifting and adjusting assembly. See [link to relevant documentation]. Figure 1-2The support assembly includes a tripod 1 and a support platform 5 fixedly mounted on the top of the tripod. A vertical pole 2 passes axially through the support platform 5 and extends downwards into the tripod sleeve 10 within the tripod cavity. The vertical pole 2 can move up and down within the support platform. The laser pointer assembly 3 includes a slot 24 and a laser pointer 25. The slot 24 is fixedly mounted horizontally on the vertical pole 2, and the laser pointer 25 is fitted into the slot. The optical fiber emitted by the laser pointer ensures that masonry work can be completed even in low-light conditions. The support platform 5 also includes an auxiliary rod 4 and a gear 22. The auxiliary rod 4 is a cylindrical rod... The auxiliary rod 4 is axially fixed to the support platform and parallel to the upright 2. A fixing sleeve 20 is fitted on the auxiliary rod 4. A diagonal brace 21 is hinged to the fixing sleeve near the upright. Bosses 9 are evenly spaced on the upright near the auxiliary rod. The diagonal brace is used to cooperate with the bosses on the upright to achieve support and fixation at different positions when the upright moves up and down. That is, when the upright moves up to a suitable position, it is supported by the diagonal brace to keep the upright in the set position and prevent it from sliding down. In addition, a bubble level 8 is installed on the support platform to ensure the levelness of the support platform, thereby ensuring that the upright is set vertically relative to the ground.

[0017] See Figure 2 and Figure 5 The upright has axially graduated lines to facilitate adjustment of the displacement of the laser pointer position. A rack 6 is fixedly laid on the right side of the upright 2 along the axial direction. Spring pieces 11 are symmetrically installed on the front and rear sides of the rack 6 by rivets 12. The spring pieces 11 extend to the left onto the upright and are engaged with the upright through a concave-convex connection structure. The rack 6 meshes with the gear 22 installed in the support platform. A handle 23 is installed on the gear 22 to drive the gear to rotate. By rotating the handle 23, the gear is driven to rotate, and further, through meshing with the rack, the upright moves up and down, thereby achieving a relatively precise adjustment of the laser pointer position.

[0018] See Figure 2 and Figure 3The lifting and adjusting assembly includes a composite clamp 7, which consists of a main clamp 15 and an auxiliary clamp 13. The main clamp 15 is fitted onto the auxiliary rod 4. A main pressure block 17 is symmetrically arranged inside the main clamp 15, clamping and fixing the rod through the main pressure block 17. The main clamp 15 and the auxiliary clamp 13 are rotatably connected by a main-auxiliary clamp shaft 14. An auxiliary pressure block 16 is symmetrically installed at the end of the auxiliary clamp 13, clamping and fixing the auxiliary pressure block 16 to the spring plate on the spur gear. In its natural state, the auxiliary pressure block 16 on the auxiliary clamp clamps secures the rod to the spur gear, and the main pressure block 17 on the main clamp fits tightly against the rod. This allows for adjustment of the rod's height by adjusting the clamping of the composite clamp, as well as for the engagement and disengagement of the spur gear with the rod. Specifically, [the following text is incomplete and requires further context: "towards..."] Pressing the auxiliary clamp handle 18 inwards widens the opening of the inner cavity of the auxiliary clamp 13, thus separating the upright from the rack, while the main clamp remains clamped to the upright. Moving the auxiliary clamp handle upwards simultaneously moves the upright upwards. Pressing the main clamp handle 19 inwards causes the main pressure block 17 and auxiliary pressure block 16 to disengage from the upright and rack, respectively, facilitating adjustment of the composite clamp's position on the auxiliary clamp. This design allows the composite clamp to move the upright up and down, enabling a rough initial positioning of the laser pointer on the upright. The vertical position of the upright can be adjusted with just one hand, and further finer adjustments can be achieved through the meshing of the gear and rack. This convenient operation improves work efficiency.

[0019] In practical use, this invention is first placed at the work site where masonry work is to be carried out. The tripod's support is adjusted using a bubble level to ensure the support platform is horizontal and the uprights are perpendicular to the platform. Then, one hand holds the auxiliary clamp handle, disengaging the main pole from the rack. The auxiliary clamp handle is held and moved upwards, simultaneously lifting the uprights. When the laser pointer on the upright reaches a near-set position, the diagonal brace supports the upright at that position. After maintaining the upright's support, the auxiliary clamp handle is released, and the main clamp handle is held, disengaging the main clamp from the uprights. The process is repeated. Hold the main clamp handle and slide it downwards along the auxiliary rod to restore the composite structure to its original position. At this time, the auxiliary pressure block on the auxiliary clamp and the spring piece on the rack engage with each other, thus re-clamping the rack and the upright. Then, rotate the handle on the gear to engage the gear and the rack, which in turn moves the upright up and down, thereby adjusting the precise position of the laser pointer on the upright. This ensures that the laser beam is accurately pointed to the set position as a control line for the masonry work. Rotating the handle on the gear moves the laser pointer to different working positions until construction is complete. Then, separate the diagonal brace from the upright and return the upright to its initial position. This invention has a simple structure and is easy to operate. The position of the upright can be adjusted with just one hand. It has a wide range of applications and can be used in the construction of various complex masonry structures. It reduces the environmental limitations on construction, and the invention provides more precise control of the line, further improving construction accuracy.

[0020] Example 2: Based on Embodiment 1, the similarities between this embodiment and Embodiment 1 will not be repeated. The difference is that the laser pointer slot is slidably connected to the pole through a sleeve fitted on the pole. In this way, when adjusting the position of the laser pointer to the next working position, the position of the laser pointer can be directly adjusted by the scale line on the pole, without having to adjust the height of the pole by rotating the drive gear. This is more convenient and faster, saves time and improves work efficiency.

[0021] Example 3: Based on Embodiment 1, the similarities between this embodiment and Embodiment 1 will not be repeated here. The difference is that the pole is a telescopic pole with a fully extended length of 3m, which further increases the applicability of the present invention.

[0022] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
