Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a locking mechanism for a steel bar measuring clamp. Background Art

[0002] Rebar measuring pliers, also known as rebar diameter measuring pliers, is a tool specially used to measure the diameter of rebar. It is suitable for use in engineering fields such as construction, bridges, and roads to measure and correct rebar. Rebar measuring pliers mainly consist of a measuring frame, a measuring starting point seat, a measuring movable seat, and a measuring scale. During use, the rebar to be measured is placed on the inner side of the measuring starting point seat and the measuring movable seat, and the measuring movable seat is held in hand and cooperated with the measuring starting point seat to clamp the rebar to be measured. The diameter of the rebar is then obtained by observing the measuring scale between the measuring starting point seat and the measuring movable seat. Since the measuring movable seat is in active rotation during use, and the position of the measuring movable seat directly affects the measurement result of the rebar, it is necessary to perform a measurement locking operation on the measuring movable seat.

[0003] In the related art, when using the steel bar measuring pliers, a spring is generally used to push the measuring movable seat into contact with the steel bar to perform measurement clamping and measurement locking operations, thereby enabling use.

[0004] However, during the current use of the steel bar measuring pliers, although a certain measuring locking force can be applied to the measuring movable seat due to the spring push method, the prerequisite is to ensure that the steel bar as a whole is in a stable state. Once the steel bar bends and shakes during the measurement process, the measuring movable seat is affected by the bending and shaking force of the steel bar, resulting in deviation in the measurement results, affecting the measurement stability and accuracy of the steel bar measuring pliers.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1-4 The utility model provides a technical solution: a locking mechanism for a steel bar measuring clamp, comprising a measuring frame 1 and a measuring locking mechanism. The left side of the rear side of the measuring frame 1 is fixedly connected to a fixing seat 2, and the right side of the fixing seat 2 is movably connected to a measuring seat 3. When the measuring seat 3 is used in conjunction with the measuring frame 1, a locking and positioning mechanism can be provided for the user to prevent the measuring seat 3 from being difficult to lock and position stably when in use, resulting in a situation where the measuring seat 3 moves horizontally and causes measurement errors, thereby improving the measurement stability and accuracy of the measuring seat 3.

[0032] Reference Figures 1-4When the measuring rod 1 is moved to the left side of the fixing plate 2, the fixing plate 7 is fixedly connected to the fixing plate 9, and the fixing plate 7 is fixedly connected to the fixing plate 9. After clamping, the locking plate 7 is driven by the locking column 6 to contact and tighten with the top of the measuring frame 1, and the measuring seat 3 and the measuring frame 1 are locked and positioned to stabilize the measurement. During this process, the scale seat 9 moves with the locking plate 7. Since the left side of the scale seat 9 is flush with the left side of the measuring seat 3, the diameter data of the steel bar can be obtained by the scale bar 8 pointed by the scale seat 9 after moving with the measuring seat 3. The locking force mechanism includes a screw groove 10, a stud 11 and a force plate 12. The screw groove 10 is opened on the locking column 6, the stud 11 is threadedly connected to the inside of the screw groove 10, the bottom of the stud 11 is fixedly connected to the top of the measuring seat 3, and the force disk 12 is fixedly connected to the top of the locking column 6. When the locking column 6 is used in conjunction with the locking plate 7, the user is provided with a medium for applying a locking and tightening positioning force to the locking column 6 and the locking plate 7, thereby avoiding the situation where it is difficult to effectively apply a locking positioning force to the measuring seat 3 when the locking column 6 and the locking plate 7 are used, thereby improving the locking force application effect of the locking column 6 and the locking plate 7.

[0033] Reference Figure 2 In a preferred embodiment, a push groove 13 is provided on the right side of the connecting seat 5, and a spring 14 is provided inside the push groove 13. One end of the spring 14 is fixedly connected to the inner wall of the push groove 13. When the connecting seat 5 is used in conjunction with the measuring seat 3, the connecting seat 5 can apply a translational force to the measuring seat 3, prompting the measuring seat 3 to actively contact the surface of the steel bar for preliminary measurement contact when in use, thereby avoiding the situation where the measuring seat 3 is difficult to actively contact the steel bar for measurement when in use, thereby improving the measurement convenience of the measuring seat 3. A accommodating groove 15 is provided on the right side of the inner wall of the connecting groove 4, and the other end of the spring 14 is fixedly connected to the inner wall of the accommodating groove 15, which can provide a retracted accommodating space for the spring 14 when the spring 14 is used in conjunction with the connecting seat 5, thereby avoiding the situation where the spring 14 is difficult to retract and accommodate when in use, thereby improving the convenience of using, retracting and accommodating the spring 14.

[0034] Reference Figure 3 When the locking plate 7 is in use, the locking post 6 is prevented from moving too far and the locking post 6 is separated from the screw, thereby improving the stability of the locking plate 7 during use.

[0035] Reference Figures 1-4 When the locking plate 7 is in use, the locking plate 7 and the locking post 6 are rotated and connected, thereby preventing the locking plate 7 from rotating with the locking post 6 or separating from the locking post 6 when the locking plate 7 is in use.

[0036] Specifically, the working process or working principle of the locking mechanism of the steel bar measuring clamp is as follows: when in use, the steel bar to be measured is moved between the fixed seat 2 and the measuring seat 3. Since the fixed seat 2 and the rear side of the measuring seat 3 are arranged in a Y shape, and the spring 14 cooperates with the push groove 13 to apply a translational thrust to the measuring seat 3 through the connecting seat 5. When the moving steel bar enters between the fixed seat 2 and the measuring seat 3, the measuring seat 3 moves to the right under the influence of the moving force of the steel bar, and cooperates with the fixed seat 2 to perform preliminary clamping work on the entering steel bar. At this time, the connecting seat 5 follows the measuring seat 3 to move inside the connecting groove 4, and performs translational connection work between the measuring seat 3 and the measuring frame 1. After the measuring seat 3 cooperates with the fixed seat 2 to clamp the measured steel bar, the locking column 6 is rotated by the force disk 12 to cooperate with the screw groove 10 and the stud 11 to apply a downward locking force to the locking column 6. At this time, the swivel 21 follows the locking column 6 The locking column 6 rotates inside the rotating cavity 20, causing the locking column 6 to drive the locking plate 7 to move downward and contact and stabilize the top of the measuring frame 1, thereby performing a measurement locking and positioning stabilization operation between the measuring seat 3 and the measuring frame 1 to ensure the measurement stability of the measuring seat 3. At this time, the following rod 17 follows the locking plate 7 to move inside the following groove 16, and performs a following connection work between the locking plate 7 and the measuring seat 3, and cooperates with the limiting groove 18 to limit the upward and downward movement of the locking plate 7 through the limit plate 19. At the same time, the top of the anti-slip pad 22 contacts the bottom of the locking plate 7, and performs a locking contact and anti-slip work between the locking plate 7 and the measuring frame 1. In this process, the scale seat 9 follows the movement of the locking plate 7. Since the left side of the scale seat 9 is flush with the left side of the measuring seat 3, the diameter data of the steel bar can be obtained by the scale bar 8 pointed to by the scale seat 9 after following the movement of the measuring seat 3, and the measurement operation of the steel bar diameter is completed.
