Description

Technical Field

[0001] The utility model relates to the technical field of house safety appraisal, in particular to a level meter for house safety appraisal. Background Art

[0002] Housing safety appraisal refers to a comprehensive inspection and assessment of a house by a professional appraisal agency or engineer, including detailed testing and analysis of the house's structure, materials, equipment, etc., to determine whether the house is safe to use. The appraisal agency or engineer will evaluate the safety of the house based on the test results and relevant standards, and put forward corresponding suggestions and measures to ensure that the house can be used safely. In the process of housing safety appraisal, the detection of the levelness of the house is an important part of the house appraisal, and a level meter is often needed to conduct safety appraisal of the house.

[0003] A Chinese utility model patent with publication number CN219796664U discloses a spirit level for housing safety appraisal, comprising a bracket body, a lifting platform fixedly connected to the top of the bracket body, a first rotating seat symmetrically fixedly connected to one end of the outer side of the lifting platform, a support plate fixedly connected to the top of the lifting platform, a mounting seat fixedly connected to the top of the support plate, a spirit level body arranged on the top of the mounting seat, and a spirit level base fixedly connected to the bottom of the spirit level body.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the safety of a house is assessed by means of a level meter body, since the level meter body is usually used outdoors, when the ground is bumpy or tilted, the above-mentioned device cannot adjust the levelness of the level meter body, thereby affecting the accuracy of the assessment of the level meter body. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a level for house safety appraisal.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A spirit level for house safety appraisal comprises a base, a plurality of support rods are hingedly connected to the side walls of the base, a ball head is arranged on the upper surface of the base, a connecting rod is fixed to the surface of the ball head, a mounting seat is arranged on the upper end of the connecting rod, a spirit level body is arranged on the upper surface of the mounting seat, a slide groove is provided on the upper surface of the base, two symmetrically arranged sliders are slidably connected to the inner wall of the slide groove, a clamping block is fixed to the upper surface of each slider, a spherical groove cooperating with the ball head is provided on the side walls of the two clamping blocks close to each other, and a driving component for driving the two sliders to move close to each other is installed on the base.

[0008] By adopting the above technical solution, when it is necessary to appraise the house, the staff moves the device to a suitable position, opens the support rod and places it on the ground, and then rotates the ball head through the mounting seat to adjust the mounting seat and the level body to a horizontal position. The driving assembly is then used to drive the two sliders to move closer to each other, so that the spherical grooves of the two clamping blocks clamp the ball head, thereby fixing the position of the mounting seat, making it easier to adjust the horizontality of the level body and improving the accuracy of the appraisal of the level body.

[0009] Furthermore, the drive assembly includes a double-headed screw that is penetrated and rotatably connected to the side wall of the base, and a star-shaped handle fixed to the end of the double-headed screw away from the base. The double-headed screw is provided with two sections of threads with equal pitch and opposite rotation directions. The two sliding blocks are both mounted on the double-headed screw and are respectively threadedly connected to the two sections of the threads of the double-headed screw.

[0010] By adopting the above technical solution, when it is necessary to drive the slider to move, the staff rotates the double-headed screw through the star-shaped handle. Since the two sliders are threadedly connected to the two sections of threads on the double-headed screw, and the two sliders are slidingly connected to the inner wall of the slide groove, the two sliders are moved closer to each other, thereby driving the clamping block to fix the ball head, reducing the probability of the level body rotating due to the rotation of the ball head.

[0011] Furthermore, a limiting assembly for limiting the position of the double-headed screw is installed on the double-headed screw, and the limiting assembly includes a fixing block sleeved on the double-headed screw and fixed to the side wall of the base, and a limiting nut sleeved on the double-headed screw and threadedly connected to the double-headed screw.

[0012] By adopting the above technical solution, after the ball head is pressed against the driving assembly, the staff needs to tighten the limit nut so that the side wall of the limit nut is pressed against the side wall of the fixed block, thereby limiting the rotation of the double-headed screw and reducing the probability of the pressing block moving due to the rotation of the double-headed screw under the action of external force.

[0013] Furthermore, an annular rubber sheet is sleeved on the double-headed screw rod, and the annular rubber sheet is located between the limiting nut and the fixing block.

[0014] By adopting the above technical scheme, the annular rubber sheet is made of rubber material, and its surface has a large friction coefficient. The side wall of the limit nut cooperates with the side wall of the fixed block and presses against the annular rubber sheet, thereby increasing the friction between the side wall of the limit nut and the side wall of the fixed block, reducing the probability of the limit nut rotating, and enhancing the limiting effect on the double-headed screw rod.

[0015] Furthermore, an anti-slip pad is fixed to the inner wall of the spherical groove.

[0016] By adopting the above technical solution, the anti-skid pad is made of rubber material, and its surface has a large friction coefficient. The spherical groove cooperates with the ball head and presses against the anti-skid pad, which increases the friction between the spherical groove and the ball head and reduces the probability of the ball head rotating in the spherical groove.

[0017] Furthermore, a bubble level is fixed to the side wall of the mounting seat.

[0018] By adopting the above technical solution and setting the bubble level, the staff can observe the horizontality of the mounting seat through the bubble level when adjusting the mounting seat, which is convenient for leveling the level body.

[0019] Furthermore, the mounting seat is sleeved on the connecting rod and is threadedly connected to the connecting rod.

[0020] By adopting the above technical solution, the mounting seat is threadedly connected to the connecting rod, so that the mounting seat and the connecting rod are detachably connected, which facilitates the removal of the mounting seat for maintenance and repair of the level body.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when it is necessary to identify a house, the staff moves the device to a suitable position, opens the support rod and places it on the ground, and then rotates the ball head through the mounting seat to adjust the mounting seat and the level meter body to a horizontal position, and then uses the driving assembly to drive the two sliders to move closer to each other, so that the spherical grooves of the two abutting blocks abut against the ball head, thereby fixing the position of the mounting seat, facilitating adjustment of the horizontality of the level meter body, and improving the accuracy of the level meter body identification;

[0023] 2. In this application, when the slider needs to be driven to move, the staff rotates the double-headed screw through the star-shaped handle. Since the two sliders are threadedly connected to the two sections of threads on the double-headed screw, and the two sliders are slidably connected to the inner wall of the slide groove, the two sliders move closer to each other, thereby driving the abutment block to fix the ball head, reducing the probability of the level body rotating due to the rotation of the ball head;

[0024] 3. In this application, after the ball head is pressed against the driving assembly, the staff needs to tighten the limit nut so that the side wall of the limit nut is pressed against the side wall of the fixed block, thereby limiting the rotation of the double-headed screw and reducing the probability of the pressing block moving due to the rotation of the double-headed screw under the action of external force.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] like Figure 1-3 As shown, an embodiment of the present application discloses a spirit level for housing safety appraisal, including a base 1, a support rod 2, a ball head 3, a connecting rod 4, a mounting seat 5, a spirit level body 51, a slider 6, a tightening block 7 and a driving assembly 8.

[0031] The base 1 is a round block structure, and a slide groove 101 is provided on the upper surface of the base 1. The support rod 2 is hinged on the side wall of the base 1, and a plurality of support rods 2 are provided. The ball head 3 is a spherical structure, and the ball head 3 is provided on the upper surface of the base 1. The connecting rod 4 is a vertically arranged round rod structure, and the connecting rod 4 is fixed on the surface of the ball head 3. The mounting seat 5 is a round block structure, and the mounting seat 5 is provided on the upper end of the connecting rod 4. The level body 51 is a level body 51 commonly used in the prior art and applicable to the present embodiment. The level body 51 is used to identify the safety of the house, and the level body 51 is provided on the mounting seat 5. The slider 6 is a rectangular parallelepiped structure, and the slider 6 is slidably connected to the inner wall of the slide groove 101, and two sliders 6 are symmetrically provided. There are two tightening blocks 7, and the two tightening blocks 7 are respectively fixed to the upper surfaces of the two sliders 6, and the side walls of the two tightening blocks 7 close to each other are provided with spherical grooves 71 that cooperate with the ball head 3.

[0032] The driving assembly 8 is installed on the base 1, and is used to drive the two sliders 6 to move closer to each other. The driving assembly 8 includes a double-headed screw 81 and a star-shaped handle 82. The double-headed screw 81 is a horizontally arranged rod-shaped structure. The double-headed screw 81 is arranged on the side wall of the base 1 and is rotatably connected. The double-headed screw 81 is provided with two sections of threads with equal pitch and opposite rotation. The two sliders 6 are both sleeved on the double-headed screw 81 and are respectively threadedly connected with the two sections of the threads of the double-headed screw 81. The star-shaped handle 82 is fixed to the end of the double-headed screw 81 away from the base 1, and the axis of the star-shaped handle 82 coincides with the axis of the double-headed screw 81.

[0033] When it is necessary to appraise the house, the staff moves the device to a suitable position, opens the support rod 2 and places it on the ground, and then rotates the ball head 3 through the mounting base 5 to adjust the mounting base 5 and the level body 51 to a horizontal position, and then uses the star-shaped handle 82 to rotate the double-headed screw 81. Since the two sliders 6 are threadedly connected to the two sections of threads on the double-headed screw 81, the two sliders 6 are slidingly connected to the inner wall of the slide groove 101, so that the two sliders 6 move closer to each other, so that the spherical grooves 71 of the two clamping blocks 7 are pressed against the ball head 3, thereby fixing the position of the mounting base 5, facilitating the adjustment of the horizontality of the level body 51, and improving the accuracy of the appraisal of the level body 51.

[0034] In order to reduce the probability of the double-headed screw 81 rotating under the action of external force, a limit assembly 9 is installed on the double-headed screw 81 to limit the double-headed screw 81. The limit assembly 9 includes a fixed block 91, a limit nut 92 and an annular rubber sheet 93. The fixed block 91 is a rectangular parallelepiped structure. The fixed block 91 is sleeved on the double-headed screw 81, and the fixed block 91 is fixed to the side wall of the base 1. The limit nut 92 is sleeved on the double-headed screw 81 and is threadedly connected to the double-headed screw 81. The axis of the limit nut 92 coincides with the axis of the double-headed screw 81. The annular rubber sheet 93 is sleeved on the double-headed screw 81, and the annular rubber sheet 93 is located between the limit nut 92 and the fixed block 91. After the ball head 3 is pressed against the driving component 8, the staff needs to tighten the limiting nut 92 so that the side wall of the limiting nut 92 cooperates with the side wall of the fixing block 91 and presses against the annular rubber sheet 93, thereby limiting the rotation of the double-headed screw 81, thereby reducing the probability of the pressing block 7 moving due to the rotation of the double-headed screw 81 under the action of external force. The annular rubber sheet 93 is made of rubber material, and its surface has a large friction coefficient, which increases the friction between the side wall of the limiting nut 92 and the side wall of the fixing block 91, reduces the probability of the limiting nut 92 rotating, and enhances the limiting effect on the double-headed screw 81.

[0035] In order to reduce the probability of the ball head 3 rotating in the spherical groove 71, an anti-skid pad 10 is fixed to the inner wall of the spherical groove 71. The anti-skid pad 10 is made of rubber material and its surface has a large friction coefficient. The spherical groove 71 cooperates with the ball head 3 and presses against the anti-skid pad 10, which increases the friction between the spherical groove 71 and the ball head 3, thereby reducing the probability of the ball head 3 rotating in the spherical groove 71.

[0036] In order to facilitate the leveling of the spirit level body 51 , a bubble level 11 is fixed to the side wall of the mounting seat 5 . The provision of the bubble level 11 allows the staff to observe the horizontality of the mounting seat 5 through the bubble level 11 when adjusting the mounting seat 5 , thereby facilitating the leveling of the spirit level body 51 .

[0037] In order to facilitate the maintenance and repair of the level body 51, the mounting seat 5 is sleeved on the connecting rod 4 and is threadedly connected to the connecting rod 4. The mounting seat 5 is threadedly connected to the connecting rod 4, so that the mounting seat 5 and the connecting rod 4 are detachably connected, thereby facilitating the removal of the mounting seat 5 for maintenance and repair of the level body 51.

[0038] The working principle of a level meter for house safety appraisal in this embodiment is as follows:

[0039] When it is necessary to appraise the house, the staff moves the device to a suitable position, opens the support rod 2 and places it on the ground, and then rotates the ball head 3 through the mounting base 5 to adjust the mounting base 5 and the level body 51 to a horizontal position, and then uses the star-shaped handle 82 to rotate the double-headed screw 81. Since the two sliders 6 are threadedly connected to the two sections of threads on the double-headed screw 81, the two sliders 6 are slidingly connected to the inner wall of the slide groove 101, so that the two sliders 6 move closer to each other, so that the spherical grooves 71 of the two clamping blocks 7 are pressed against the ball head 3, thereby fixing the position of the mounting base 5, facilitating the adjustment of the horizontality of the level body 51, and improving the accuracy of the appraisal of the level body 51.

[0040] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
