Description

Technical Field

[0001] The present invention belongs to the field of portable level gauges for engineering installation, and in particular relates to a portable level gauge for engineering installation. Background Art

[0002] At present, during the construction of houses, it is necessary to pre-bury cold water and hot water pipes and install hot and cold water pipe faucet thread pipe heads. In some public bathing areas such as bathhouses or gyms, multiple shower heads are required. When laying multiple groups of hot and cold water pipes, the end faces of a single group of hot and cold water pipes are kept parallel to facilitate the subsequent installation of muddy water valves. At the same time, the parallel arrangement of multiple groups of hot and cold water pipes can increase the aesthetics of the decoration.

[0003] However, existing level instruments, such as a level instrument with publication number CN119042474A, use a quick leveling tripod. By placing the device on the tripod, the tripod is placed on the side that is horizontal with the end face of the bent pipe. At this time, the position of the laser light and the end face of the bent pipe is used to judge whether the end faces of the hot and cold bent pipes are parallel. However, if at this time, the tripod needs to use the previous set of hot and cold pipes as a standard to illuminate the position of the hot and cold pipes on the other side, when the position of the tripod is changed, it will be difficult to adjust. If the mortar laid on the ground is not completely dry at this time, some mortar blocks will solidify on the bottom of the tripod, which is not easy to clean. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0039] Please refer to Figures 1 to 11 , a portable level for engineering installation, the pipeline includes a straight pipe 1 and a curved pipe 2, the upper end of the straight pipe 1 is provided with a curved pipe 2, a support frame 3 is fixed to the outer side of the curved pipe 2, and a plurality of groups of teeth 31 are fixed around the outer wall of the support frame 3, and an annular guide rail 32 is provided on both sides of the teeth 31, a clamping assembly 4 is provided on one side of the support frame 3, and an adjustment assembly 5 is rotatably provided on the outer wall of the support frame 3, the adjustment assembly 5 includes a gear 51, a limit shaft 52, a support shell 53 and a self-locking structure 54, the outer side of the teeth 31 is meshed with a gear 51, the inner side of the gear 51 is coaxially connected to the limit shaft 52, and the outer side of the gear 51 is provided with a support shell 53, the support shell 53 is provided with an arc-shaped protrusion 531 adapted to the annular guide rail 32 on the side close to the support frame 3, and the side wall of the support shell 53 is provided with a self-locking structure 54;

[0040] A laser emitting assembly 6 is fixed to the outer side of the supporting shell 53, and the laser emitting assembly 6 includes a fixing frame 61, a laser emitter 62, a telescopic rod 63 and a measuring tape 64. The supporting shell 53 is rotatably connected to the fixing frame 61 on the side away from the supporting frame 3, and at least one telescopic rod 63 is fixed to the side wall of the fixing frame 61, the laser emitter 62 is fixed to the output end of the telescopic rod 63, a measuring tape 64 is fixed between the laser emitter 62 and the fixing frame 61, and a level 8 is arranged on the side of the fixing frame 61 away from the supporting frame 3.

[0041] When in use, the clamping assembly 4 is opened and the support frame 3 is sleeved on the outside of the curved pipe 2, and then the clamping assembly 4 is closed inward and the support frame 3 is fixed to the outer wall of the curved pipe 2. When measuring whether the end faces of multiple curved pipes 2 are horizontal, the operator releases the self-locking state of the self-locking structure 54 and drives the support shell 53 to rotate along the annular guide rail 32 on the support frame 3 by hand. During the rotation process, the gear 51 is engaged with the teeth 31 until the light beam emitted by the laser emitter 62 is irradiated on the end face of the curved pipe 2. At this time, the bubble in the level 8 can be observed to determine whether the laser emitter 62 is in a horizontal state by whether the bubble moves to the center of the surface of the level 8. If it is in a horizontal state, the self-locking structure 54 is tightened on the outside of the gear 51, and the gear 51 and the laser emission assembly 6 are tightened by friction. Limitation, reduce the relative displacement between the gear 51 and the support frame 3, at this time, drag the laser emitter 62 to move toward the end away from the fixed frame 61, so that the telescopic rod 63 extends outward. Since the output end of the telescopic rod 63 is fixedly connected to the end of the tape measure 64, when the telescopic rod 63 is extended, it can drive the tape measure 64 to be pulled outward, and the light beam emitted by the laser emitter 62 is always emitted by the laser emitter 62 toward the center of the clamped curved pipe 2 until the light beam emitted by the laser emitter 62 is parallel to the end face of the curved pipe 2. At this time, the stretched length of the tape measure 64 can be recorded. When the two curved pipes 2 are leveled next time, the position of the support frame 3 and the end face of the curved pipe 2 can be corrected by recording the stretched length of the tape measure 64, so as to detect whether the position of the support frame 3 has changed. At the same time, the support frame 3 can also be fixed on the straight pipe 1 as shown in FIG. Figure 3 , check the parallelism of the end face of straight pipe 1.

[0042] Please refer to Figure 1In some cases, if the end face of the curved pipe 2 is not cut in advance or the end face of the curved pipe 2 is not cut smoothly, the light beam emitted by the laser emitter 62 cannot pass through the curved pipe 2 smoothly. At this time, the staff can cut along the light beam. Since there is a certain distance between the end face of the curved pipe 2 and the support frame 3, it is not necessary to disassemble the level gauge during the cutting process. At the same time, since the curved pipe 2 may be relatively displaced during the cutting process, and the relative position between the support frame 3 and the curved pipe 2 is fixed, the laser emitter 62 does not need to be adjusted in a large range when irradiating the end face of the curved pipe 2, so that it is convenient to use. If the light emitted by the laser emitter 62 passes through the clamped curved pipe 2 and irradiates onto the end face of another curved pipe 2, the position relationship between the light and the second curved pipe 2 can be observed to detect the two curved pipes 2. Whether they are on the same horizontal plane, if there is another curved pipe 2 on the other side of the clamped curved pipe 2, that is, the three curved pipes 2 are arranged in parallel, and the clamped curved pipe 2 is located in the middle of the three curved pipes 2, when it is necessary to detect whether the end face of the curved pipe 2 is level with the end face of the curved pipe 2 on the other side, the self-locking state of the self-locking structure 54 can be released to drive the gear 51 on the supporting shell 53 to engage with the tooth 31 until it rotates to the side where the middle curved pipe 2 is away from the curved pipe 2 to be tested. At this time, the light beam emitted by the laser emitter 62 passes through the middle curved pipe 2 and irradiates the front end of the curved pipe 2 to be tested, so that the irradiation direction of the laser emitter 62 can be changed without changing the position between the clamping assembly 4 and the curved pipe 2, thereby facilitating the end face leveling of the curved pipes 2 at different angles, and there is no need to frequently change the position of the clamping assembly 4 during the leveling process.

[0043] The clamping assembly 4 includes an arc frame 41, a threaded rod 42 and a connecting rod 43, and the side wall of the support frame 3 is fixed with a threaded rod 42, and the threaded rod 42 is respectively provided with a left-handed thread and a right-handed thread from the middle to the two ends, and the outer side of the threaded rod 42 is threadedly connected to two arc frames 41, and the two arc frames 41 are respectively connected to the left-handed thread and the right-handed thread, and the end of the arc frame 41 away from the threaded rod 42 is provided with a connecting rod 43 that penetrates the arc frame 41.

[0044] Please refer to Figure 1 , Figure 2 and Figure 6When in use, the arc frame 41 is symmetrically arranged about the vertical center line of the support frame 3. When the threaded rod 42 is rotated, the lower end of the arc frame 41 is slidably arranged with the connecting rod 43, and the arc frame 41 is axially restricted by the connecting rod 43, so that when the threaded rod 42 rotates, the two arc frames 41 are driven by the thread to slide synchronously toward the middle of the threaded rod 42, thereby clamping and restricting the bent pipe 2. Since the arc frame 41 is coaxially arranged with the support frame 3, when the arc frame 41 is coaxially clamped on the outer wall of the bent pipe 2, the bent pipe 2 is coaxially arranged with the support frame 3, and the clamping assembly 4 can be used to fix the support frame 3 on the bent pipe 2, and can also be coaxially arranged with the support frame 3, so that when the adjustment assembly 5 rotates around the support frame 3, it can rotate with the center of the bent pipe 2, which is beneficial to improve the rotation stability of the laser emitting assembly 6.

[0045] Please refer to Figure 7 A threaded hole 532 is formed on the side wall of the support shell 53, and the self-locking structure 54 includes an adjusting screw 541 and a rubber pad 542. The inner side of the threaded hole 532 is threadedly connected with the adjusting screw 541, and the adjusting screw 541 is located at one end of the support shell 53 and fixed with a rubber pad 542.

[0046] When the support shell 53 is moved to a suitable position, the support shell 53 needs to be fixed. At this time, the adjusting screw 541 is rotated to make the adjusting screw 541 move inward along the threaded hole 532 until the rubber pad 542 on the adjusting screw 541 fits with the gear 51, thereby supporting the gear 51 through the rubber pad 542 to increase the static friction between the gear 51 and the adjusting screw 541, thereby restricting and fixing the gear 51. At this time, the self-locking structure 54 is in a self-locking state, and when the adjusting screw 541 is rotated in the opposite direction, the adjusting screw 541 is moved to the end away from the gear 51, thereby reducing the static friction between the gear 51 and the adjusting screw 541, thereby releasing the self-locking state of the self-locking structure 54, and limiting the rotation of the gear 51 in this way. The fixing position in this way is relatively fixed in the hole inserted into the gear 51, which is more flexible and not restricted by the position of the hole.

[0047] Please refer to Figure 7 A stopper 521 is fixed to the outer wall of the limiting shaft 52 , and the stopper 521 is located at a side away from the self-locking structure 54 , and a dust cover 533 is provided on the inner side of the supporting shell 53 .

[0048] The limit shaft 52 is coaxially arranged with the gear 51. When the adjusting screw 541 squeezes the gear 51, the gear 51 tends to slide away from the adjusting screw 541. At this time, the gear 51 is blocked by the stop block 521. At this time, the gear 51 is blocked by the adjusting screw 541 and the stop block 521 and can be locked and does not continue to rotate. At the same time, the stop block 521 is located on the outside of the tooth 31. At this time, the position of the gear 51 can be limited by the stop block 521 to prevent it from sliding along the limit shaft 52, so that the gear 51 can always be able to mesh with the tooth 31.

[0049] A rotating seat 501 is fixed to the upper end surface of the supporting shell 53 , and a rotating core 502 is rotatably disposed inside the rotating seat 501 , and the upper end surface of the rotating core 502 is fixed to the lower end surface of the fixing frame 61 .

[0050] A positioning hole 5011 is provided on the side wall of the rotating seat 501, and an insertion rod 5013 is provided through the inner side of the positioning hole 5011. Two through holes 5012 that penetrate the rotating core 502 are provided on the inner side of the rotating core 502. The central axes of the two through holes 5012 are perpendicular to each other. When the positioning hole 5011 is coaxial with a through hole 5012, the insertion rod 5013 can penetrate the positioning hole 5011 and be inserted into the through hole 5012.

[0051] Please refer to Figure 7 When in use, when it is necessary to rotate the fixing frame 61 to change the light output direction of the laser emitter 62, the rod 5013 is pulled out from the through hole 5012. At this time, the fixing frame 61 and the rotating core 502 are rotated to rotate along the rotating seat 501. When the rotating core 502 is rotated to a suitable position, the rod 5013 is inserted into the through hole 5012 along the positioning hole 5011, so as to fix the rotating core 502 and the fixing frame 61. At the same time, since the central axes of the two through holes 5012 are perpendicular to each other, the laser emitter 62 can be located at a more accurate position after each rotation and fixation. Moreover, since the rotation angle is fixed, this fixing method can more accurately fix it in a suitable position, reduce the flexibility of angle fixing, and thus reduce the fine-tuning process.

[0052] A first hinge seat 631 is provided at the upper end of the telescopic rod 63, and a second hinge seat 632 parallel to the first hinge seat 631 is provided on the side of the fixing frame 61 close to the telescopic rod 63, and a multi-section telescopic rod 7 is rotatably provided between the first hinge seat 631 and the second hinge seat 632.

[0053] Please refer to the figure to Fig.11When the telescopic rod 63 is pulled out during use, since the telescopic rod 63 is thin and the laser emitter 62 is located at the end of the telescopic rod 63, the telescopic rod 63 is easily bent. At this time, the two ends of the multi-section telescopic rod 7 are respectively connected to the end of the telescopic rod 63 and the fixed frame 61, so that a triangular structure is formed between the fixed frame 61, the telescopic rod 63 and the multi-section telescopic rod 7 to improve the stability of the multi-section telescopic rod 7 and reduce the deformation of the end of the telescopic rod 63, which is beneficial to improve the stability of the movement of the laser emitting assembly 6.

[0054] An axis core 641 is fixed to the inner side of the fixing frame 61, and the measuring tape 64 is wound around the outer side of the axis core 641. A locking seat 642 is provided on the outer side of the measuring tape 64, a measuring tape shell 643 is fixed to the outer side of the measuring tape 64, and a pointer 644 is fixed to the side of the fixing frame 61 close to the telescopic rod 63.

[0055] When in use, the measuring tape 64 is wound around the outside of the shaft core 641, and the end of the measuring tape 64 passes through the measuring tape shell 643 and is fixed to the end of the telescopic rod 63, so that when the telescopic rod 63 is extended, the measuring tape 64 can extend outward along with the telescopic rod 63, and is used to record the distance between the laser emitting assembly 6 and the support frame 3, and can also assist in measuring the port length of the bent pipe 2. The extended length of the measuring tape 64 and the telescopic rod 63 is determined by the position of the scale line on the measuring tape 64 pointed to by the pointer 644.

[0056] The locking seat 642 includes a pressure plate 6421, a slide rail 6422 and a slider 6433. A pressure plate 6421 is slidably arranged on the outer side of the tape measure 64. The outer wall of the tape measure shell 643 is provided with a slide rail 6422 that penetrates the tape measure shell 643. A slider 6433 is fixed to one end of the pressure plate 6421 close to the slide rail 6422. A protrusion 6434 is arranged on the outer side of the slider 6433.

[0057] During use, if it is necessary to fix the extended length of the tape measure 64, the user presses the slider 6433 with his fingers and pushes the slider 6433 inward, so that the pressure plate 6421 squeezes the tape measure 64, thereby increasing the static friction between the tape measure 64 and the pressure plate 6421, and limiting the position of the tape measure 64, reducing the inward pulling force when the tape measure 64 is rewound, thereby reducing the pulling force on the laser emitter 62.

[0058] The level 8 is a rectangular glass body, and the multiple sides of the level 8 away from the fixing frame 61 are provided with collimators;

[0059] When the laser emitting assembly 6 is in a horizontal state, the bubble moves upward. At this time, the alignment on the upper end face of the level 8 can be compared with the bubble. When the laser emitting assembly 6 rotates 90 degrees with the support frame 3 as the center, the bubble moves upward. At this time, the alignment on the side wall of the level 8 can be compared with the bubble position to detect whether the laser emitting assembly 6 is in a horizontal state. This is beneficial for the level 8 to still be able to calibrate whether the laser emitter 62 is horizontal after the laser emitter 62 changes direction.

[0060] The portable level for engineering installation provided by the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0061] When in use, the support frame 3 is sleeved on the outside of the curved pipe 2, and the arc frame 41 is clamped on both sides of the curved pipe 2, and then the threaded rod 42 is rotated to drive the two arc frames 41 to move inward, so as to be clamped on the outside of the curved pipe 2. At this time, according to actual needs, when measuring whether the end faces of the two curved pipes 2 are parallel, the support shell 53 is rotated to make the gear 51 mesh with the tooth 31, and at the same time, the support shell 53 is rotated to a suitable position with the support frame 3 as the center of the circle, and then the position of the bubble on the level 8 is used to determine whether the laser emitter 62 is parallel. When it is parallel, the gear 51 is fixed, and then the laser emitter 62 is pulled outward, thereby driving the telescopic rod 63 and the multi-section telescopic rod 7 to be pulled outward until the light emitted by the laser emitter 62 passes through the clamped end face of the curved pipe 2, and observe. The positional relationship between the light and the end face of another curved tube 2 can intuitively show whether the end faces of the two curved tubes 2 are parallel, that is, when the three curved tubes 2 are arranged in parallel and the clamped curved tube 2 is located in the middle of the three curved tubes 2, when it is necessary to detect whether the end faces of the curved tube 2 and the curved tube 2 on the other side are level, the self-locking state of the self-locking structure 54 can be released to drive the gear 51 on the support shell 53 to engage with the tooth 31 until it rotates to the side of the middle curved tube 2 away from the curved tube 2 to be tested. At this time, the light beam emitted by the laser emitter 62 passes through the middle curved tube 2 and irradiates the front end of the curved tube 2 to be tested, so that the irradiation direction of the laser emitter 62 can be changed without changing the position between the clamping assembly 4 and the curved tube 2, thereby facilitating the end face leveling of the curved tubes 2 at different angles.
