Description

Technical Field

[0001] The utility model relates to the technical field of exposed steel bar adjustment tools, in particular to a practical composite plate steel bar exposure adjustment device. Background Art

[0002] Currently, in the production process of composite slabs, a mold is first installed, and then a steel bar skeleton is tied inside the mold. When adjusting the exposed steel bars, a practical composite slab steel bar exposure adjustment device is needed.

[0003] For example, a practical composite plate steel bar exposure adjustment tool with the authorization announcement number "CN 217169016 U" is provided. When it is necessary to adjust the steel bars of the composite plate steel bar skeleton located in the mold, first hold the rod body and insert the adjustment rod under the steel bar skeleton. Then, apply force to the rod body 1 to pull or pry the steel bar upwards, so that the steel bar to be adjusted is displaced, thereby preventing the overall steel bar skeleton from shifting during the adjustment process. When it is necessary to adjust the exposed steel bars of the composite plate steel bar skeleton located outside the mold, a ring can be used to be placed on the exposed steel bar. Then, the rod body is pulled to move the steel bar toward the inside or outside of the mold, thereby adjusting the exposed length of the exposed steel bar. By pulling instead of knocking, the exposed steel bar is adjusted to avoid the vibration caused by knocking that causes the overall steel bar skeleton to loosen and then cause displacement or deformation of the steel bar. However, during use, the prying head needs to be pressed against the composite plate, and the steel bar is pried through the groove of the prying head. The exposed steel bar is adjusted by using the lever principle. However, the length of the rod body of the device is fixed and the length of the rod body cannot be adjusted, which increases the limitations of the device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the prying head needs to be pressed against the composite plate during use, the steel bars are pried by the groove of the prying head, and the exposed steel bars are adjusted by using the lever principle. However, the length of the rod body of the device is fixed and the length of the rod body cannot be adjusted, which increases the limitations of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A practical composite plate steel bar exposure adjustment device is designed, which includes a sleeve and a sliding rod. The inner wall of the sleeve is slidably connected to the sliding rod. A stretching device is provided inside the sliding rod. The left end of the sleeve is fixedly connected to a handle, and the outer wall of the handle is fixedly connected to a rubber pad.

[0007] Preferably, the stretching device includes a fixed rod and a spring, both ends of the fixed rod are fixedly connected to the sliding rod, a spring is provided on the outer wall of the fixed rod, both ends of the spring are fixedly connected to the sliding rod and the slide plate respectively, a protrusion is fixedly connected to the outer side of the slide plate, and a ball bearing is installed on the inner wall of the upper end of the protrusion.

[0008] Preferably, the inner wall of the slide plate is slidably connected to the fixing rod, and the outer wall of the protrusion is slidably connected to the sleeve and the slide rod.

[0009] Preferably, the right end of the sliding rod is fixedly connected to a connector.

[0010] Preferably, a threaded hole is machined on the surface of the connector.

[0011] Preferably, the connecting head is fixedly connected to the pry head by bolts.

[0012] The utility model proposes a practical device for adjusting the exposed steel bars of a composite plate, which has the beneficial effect that: through the cooperation of the stretching device and the sliding rod, when it is necessary to adjust the length between the sleeve and the sliding rod, the operator presses the balls on both sides to move the balls inward, and the balls drive the protrusions and the slide plate to move inward synchronously, compressing the spring, and the protrusions are no longer plugged into the sleeve. The operator stretches the sliding rod outward, and the movement of the sliding rod drives the protrusions and the balls to move synchronously. When the ball moves to the next through hole, the reaction force of the spring pushes the protrusions and the balls to move outward. By fixing the position of the sliding rod with the protrusions and the balls, the operator can make multiple adjustments according to actual needs to meet different work requirements and reduce work limitations.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Refer to the attached Figure 1-6 : In this embodiment, a practical composite plate steel bar exposure adjustment device includes a sleeve 1 and a sliding rod 4. The inner wall of the sleeve 1 is slidably connected to the sliding rod 4. The sliding rod 4 slides inside the sleeve 1. A stretching device 2 is provided inside the sliding rod 4. The left end of the sleeve 1 is fixedly connected to a handle 5, which is convenient for the operator to use. The outer wall of the handle 5 is fixedly connected to a rubber pad 6, which provides a comfortable and soothing effect on the operator's hands.

[0022] The inner wall of the slide 203 is slidably connected to the fixed rod 201, and the fixed rod 201 limits the position and movement track of the slide 203. The outer wall of the protrusion 204 is slidably connected to the sleeve 1 and the slide rod 4. The protrusion 204 slides inside the sleeve 1 and the slide rod 4. The right end of the slide rod 4 is fixedly connected to a connector 7, and a threaded hole is processed on the surface of the connector 7. The connector 7 is fixedly connected to the pry head 3 through a bolt 8.

[0023] Refer to the attached Figure 1-4 : The stretching device 2 includes a fixed rod 201 and a spring 202. The elastic coefficient of the spring 202 can be adjusted according to actual requirements to meet the working needs. The two ends of the fixed rod 201 are fixedly connected to the slide rod 4. A spring 202 is provided on the outer wall of the fixed rod 201. The two ends of the spring 202 are respectively fixedly connected to the slide rod 4 and the slide plate 203. A protrusion 204 is fixedly connected to the outside of the slide plate 203. The movement of the slide plate 203 drives the protrusion 204 to move synchronously. A ball 205 is installed on the inner wall of the upper end of the protrusion 204, and the ball 205 can roll inside the protrusion 204.

[0024] Working principle:

[0025] When it is necessary to adjust the exposed steel bars of the composite plate, the operator holds the rubber pad 6 on the surface of the handle 5. The rubber pad 6 is elastic and can reduce the reaction force of the handle 5 on the operator's hand. The operator inserts the connecting end of the pry head 3 into the connector 7, and fixes the connector 7 and the pry head 3 by screwing the bolt 8 into the connector 7. After the pry head 3 is fixed, the stretching device 2 is adjusted to adjust the length of the sleeve 1 and the slide bar 4. The operator adjusts the telescopic length between the sleeve 1 and the slide bar 4 by himself to increase practicality, and aligns the pry head 3 with the exposed steel bars so that the two sides of the pry head 3 are pressed against the outer wall of the composite plate, and the middle groove of the pry head 3 is in contact with the exposed steel bars. The operator applies a downward force to the handle 5, and bends the exposed steel bars downward through the pry head 3 to complete the adjustment process of the exposed steel bars of the composite plate.

[0026] Stretching process of sleeve and slide rod:

[0027] When the length between the sleeve and the slide bar needs to be adjusted, the operator presses the balls 205 on both sides to make the balls 205 move inward, and the balls 205 drive the protrusions 204 and the slide plate 203 to move inward synchronously, compressing the spring 202. The protrusions 204 are no longer plugged into the sleeve 1. The operator stretches the slide bar 4 outward, and the movement of the slide bar 4 drives the protrusions 204 and the balls 205 to move synchronously. When the balls 205 move to the next through hole, the reaction force of the spring 202 pushes the protrusions 204 and the balls 205 to move outward, so that the protrusions 204 and the balls 205 fix the position of the slide bar 4. The operator can make multiple adjustments according to actual needs to meet different work requirements and complete the stretching process of the sleeve and the slide bar.
