Description

Technical Field

[0001] The utility model relates to the technical field of mortar detectors, in particular to a mortar strength detector. Background Art

[0002] The mortar strength tester is a device used for on-site rapid testing of the mortar strength in masonry joints. It uses a mechanical penetration method to test the compressive strength of the mortar by measuring the penetration depth of the nail. During the masonry process, mortar is needed to bond adjacent blocks, and the strength of the mortar also affects the overall strength of the completed masonry. Therefore, after the masonry is completed, it is necessary to sample and test the strength of the mortar in the mortar joints to determine whether the mortar strength meets the requirements.

[0003] After searching, a new type of mortar strength tester disclosed in a Chinese patent with publication number CN218412544U is technically characterized in that it includes a tester body, a trigger arranged on the wall surface of the tester body, grips arranged on both sides of the outer wall of the tester body, and a force groove rod slidably inserted into one end of the tester body, a circular ring is slidably sleeved on the outer wall of the tester body, handles are fixedly connected to both sides of the outer wall of the circular ring, and a push plate is fixedly connected to the rear edge of the lower end of the circular ring; the beneficial effects of the utility model are as follows: through the coordinated use of the handle, the grip, the circular ring, the push plate, the U-shaped block, the cylinder, the force groove rod and the elastic mechanism, the hook inside the mortar strength tester can be hung up with the help of an external tool arc-shaped force lever, and after the hook inside the mortar strength tester is hung up, the circular ring can be restored to its original position, and the operation is simple.

[0004] Although the force slot rod can be hung on the hook in the above scheme, the staff needs to pinch the handle and the grip to shorten the distance when using it. The grip pushes the ring to move, and the ring pushes the push plate to move backward, driving the force slot rod to slide backward and hang on the hook to combine. While the force slot rod slides, the working spring inside the detector body needs to be compressed. It requires a lot of force to compress the working spring inside the detector body, which is very strenuous when using. Moreover, for some staff with less strength or female staff, they may not have the strength to pinch and compress the working spring after long-term use, which is very inconvenient for the staff to use.

DETAILED DESCRIPTION

[0021] See also Figures 1 to 4 A mortar strength tester includes a tester body 1 and a pull rod 2, the outer surface of the pull rod 2 is slidably connected to the inner wall of the tester body 1, a slide groove 3 is opened on the inner side of the pull rod 2, a force plate 4 is arranged outside the tester body 1, a support rod 5 is fixedly connected to the inner side of the force plate 4, the outer surface of the support rod 5 is in sliding contact with the inner wall of the slide groove 3, the force plate 4 is L-shaped, the force plate 4 is located on the inner side of one end of the pull rod 2 and is rotatably connected to an auxiliary wheel 7, and a control mechanism 6 is arranged outside the tester body 1.

[0022] In this embodiment: when the force plate 4 moves backward and contacts with the slide groove 3 through the support rod 5, it can drive the pull rod 2 to slide successively, and the pull rod 2 can be hung on the hook. When the force plate 4 is moved backward, the auxiliary wheel 7 contacts with the detector body 1, which can reduce friction and facilitate the movement of the force plate 4. The length of the slide groove 3 can prevent the pull rod 2 from being blocked by the support rod 5 after being released.

[0023] As a technical optimization scheme of the utility model, the control mechanism 6 includes a loading box 601, the lower surface of the loading box 601 is fixedly connected to the outer surface of the detector body 1, the inner wall of the loading box 601 is slidably connected with a stopper 602, one side of the stopper 602 is fixedly connected with a guide rod 603, the inner bottom wall of the loading box 601 is fixedly connected with a positioning plate 604, the outer surface of the guide rod 603 is slidably connected to the inner wall of the positioning plate 604, and the end of the guide rod 603 away from the stopper 602 is fixedly connected to a limiting block 605.

[0024] In this embodiment: the control mechanism 6 can limit the movement of the force plate 4, and the fixed restriction can be released when the force plate 4 is needed. The loading box 601 can support the stability and direction guidance of the block 602 during sliding. The end of the block 602 located outside the loading box 601 has an inclined angle. The positioning plate 604 can block the limit block 605, and the sliding distance of the block 602 can be controlled by the limit block 605.

[0025] As a technical optimization solution of the utility model, a spring 606 is sleeved on the outside of the guide rod 603 , one end of the spring 606 is fixedly connected to one side of the stopper 602 , and the other end of the spring 606 is fixedly connected to one side of the positioning plate 604 .

[0026] In this embodiment, the spring 606 can elastically support the stopper 602, so that the stopper 602 is always outside the loading box 601 when not pushed by external force.

[0027] As a technical optimization solution of the present invention, a groove 607 is provided on the inner side of the force plate 4 , and the outer surface of the stopper 602 is in sliding contact with the inner wall of the groove 607 .

[0028] In this embodiment: the groove 607 has an inclination angle that matches the stopper 602. The stopper 602 is pushed out by the spring 606 and contacts the groove 607. In the absence of external force, the stopper 602 is always in the groove 607 under the elastic support of the spring 606. After the external force pulls the force plate 4, the stopper 602 is pushed to slide into the loading box 601 due to the influence of the inclination angle of the groove 607.

[0029] As a technical optimization solution of the present utility model, a support block 8 is fixedly connected to the outer surface of the detector body 1 , and the support block 8 is parallel to the auxiliary wheel 7 .

[0030] In this embodiment: In different work sites, the pull rod 2 sometimes needs to be adjusted. When the pull rod 2 needs to be slid further toward the outside of the detector body 1, the force plate 4 located at one end of the slide groove 3 needs to be processed longer to meet the needs of the pull rod 2. The support block 8 can increase the stroke of the force plate 4.

[0031] As a technical optimization solution of the present utility model, a base 9 is fixedly connected to the outer surface of the detector body 1, and a handle 10 is movably connected to the inner side of the base 9 at a fixed point.

[0032] In this embodiment, through the movable connection between the handle 10 and the base 9 , the staff can adjust the handle 10 to the most suitable angle when using it, so that the staff can pull the force plate 4 through the handle 10 .

[0033] As a technical optimization solution of the present invention, a clamp 11 is fixedly connected to the outer surface of the detector body 1 , and the inner wall of the clamp 11 is in sliding contact with the outer surface of the handle 10 .

[0034] In this embodiment, the clamp 11 has an elastic function. When the handle 10 is not in use, the handle 10 can be placed in the clamp 11 to limit the movement of the handle 10 to prevent the movement of the handle 10 from affecting the use of the mortar strength tester by the staff.

[0035] Working principle: When the pull rod 2 needs to be hung on the hook when using the detector body 1, first pull the handle 10 out of the clip 11, and then pull the handle 10 backward to drive the force plate 4 to move backward. While the force plate 4 moves backward, the block 602 is pushed by the groove 607 to slide inside the loading box 601, and at the same time, the block 602 compresses the spring 606. After the block 602 is out of contact with the groove 607, the spring 606 pushes the block 602 to slide outside the loading box 601, and then continues to pull the force plate 4 backward. At the same time, the auxiliary wheel 7 contacts the support block 8, and then the auxiliary wheel 7 contacts the detector body 1 to rotate. When a click is heard, it means that the pull rod 2 is hung on the hook. When the force plate 4 is not used, the same principle applies, and the opposite operation is performed.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
