Description

Technical Field

[0001] The utility model belongs to the technical field of sample making moulds, in particular to a concrete sample making mould for building construction. Background Art

[0002] In construction, concrete sample molds are tools used to make concrete specimens for strength and other physical property tests. These molds can help engineers and construction workers ensure that the quality of concrete meets specific technical parameters. Therefore, it can be seen that existing sample molds basically meet people's usage needs, but the following problems still exist.

[0003] When the operator is making a concrete mold, the operator pours concrete into the mold, and after the concrete solidifies, the operator takes the concrete out of the mold. When the operator takes out the solidified concrete in the mold, the operator first turns the mold over, and then the solidified concrete sample falls off from the mold under the action of gravity. However, the operator may need to turn the sample mold over when demoulding. Since the concrete is poured into the sample mold, the gravity of the sample mold may increase, which may make it inconvenient for the operator to turn the mold over. Moreover, after the operator turns the sample mold over, the concrete sample in the sample mold descends under the action of gravity. The descending speed is too fast, which may cause the concrete sample to hit the ground, which may cause the concrete to bump. For this reason, we propose a concrete sample mold for construction. Utility Model Content

[0004] The utility model provides a concrete sample mold for construction, wherein the mold cavity rotates within a support frame, and a push plate supports the mold cavity opening, so that the push plate supports the mold cavity opening. Then, the operator drives a sliding rod through a gear to move, so that the sliding rod drives the push plate to move downward. The push plate moves downward, and the push plate facilitates the gradual removal of the concrete sample from the mold cavity, thereby improving the convenience of demoulding for the operator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete sample making mold for construction, comprising a mold cavity, a support frame is provided on the surface of the mold cavity, and the mold cavity is rotatably connected to the support frame, a sliding sleeve is symmetrically fixed to the inner wall of the support frame, and a sliding rod is inserted in the middle of the sliding sleeve, and a push plate is fixed to the end of the sliding rod for sliding connection with the inner wall of the support frame, the push plate and the end of the mold cavity fit together, the outer wall of the sliding sleeve is fixed with a rotating sleeve, and a gear is embedded in the middle of the rotating sleeve, and a rotating rod passing through the rotating sleeve is connected to each other in the middle of the gear, and the gear is fixed with a rotating disk fitted on the surface of the rotating sleeve at the end away from the rotating rod, and one side of the gear is meshed with a tooth groove provided on the sliding rod.

[0006] Furthermore, the mold cavity is provided with a stopper, and a positioning block is fixed on one side where the stopper and the mold cavity are in contact with each other, and the surface of the positioning block is provided with a positioning groove opened on the mold cavity.

[0007] Furthermore, the blocking member may be a vertical baffle, and the vertical baffle is laterally arranged in the mold cavity.

[0008] Furthermore, the baffle may be a transverse baffle, which is vertically arranged in the mold cavity.

[0009] Furthermore, rotating shafts penetrating the support frame are symmetrically fixed to both side ends of the mold cavity, and the surfaces of the rotating shafts are sleeved with first extension sleeves fixed to the support frame.

[0010] Furthermore, the turntable is provided with a ring passing through one side of the rotating sleeve and the surface of the rotating rod, and a pull frame is fixed on either side of the ring surface. A limit rod fixed on the outer wall of the sliding sleeve passes through the middle of the pull frame, and the surface of the limit rod is wrapped with a second spring that respectively abuts between the inner wall of the pull frame and the surface of the sliding sleeve.

[0011] Furthermore, a slider is fixed on one side of the push plate close to the inner wall of the support frame, and the surface of the slider is sleeved with a sliding groove opened on the inner wall of the support frame.

[0012] Furthermore, traction grooves fixed on the support frame are symmetrically provided on both sides of the sliding sleeve, and a first spring and a traction rod are respectively provided inside the traction groove.

The end of the traction rod is fixed on the inner wall of the push plate.

[0013] The beneficial effects of the utility model are:

[0014] 1. The concrete sample making mold for construction is provided with a rotating shaft, a gear, a rotating rod, a turntable, a sliding rod, a sliding sleeve and a tooth groove. When the operator pushes the mold cavity, the mold cavity rotates in the support frame through the rotating shaft, and the opening of the mold cavity is blocked by the push plate. Then the operator rotates the turntable, and the turntable drives the gear and the tooth groove to engage with each other, so that the tooth groove drives the push plate to move through the sliding rod. After the push plate is removed from the mold cavity opening, the concrete sample in the mold cavity falls off from the mold cavity under the action of gravity, and the concrete sample is supported by the push plate to avoid collision of the concrete sample during demoulding, thereby improving the convenience of falling off of the concrete sample.

[0015] 2. The concrete sampling mold for construction is provided with a vertical baffle, a positioning block, a positioning groove and a transverse baffle. The positioning block is driven by the transverse baffle to be inserted into the positioning groove, so that the cavity in the mold cavity becomes a whole, which is convenient for the production of a single long strip of concrete sample. When the operator moves the vertical baffle, the vertical baffle drives the positioning block to be inserted into the positioning groove, so that the vertical baffle divides the space in the mold cavity into several parts, which is convenient for the operator to sample several groups of concrete samples at the same time, thereby improving the scope of use of the operator.

The end of the gear 22 away from the rotating rod 17 is welded with a turntable 24 that fits on the surface of the rotating sleeve 21. One side of the gear 22 is meshed with the tooth groove 14 provided on the slide rod 15. When the operator is making samples, the operator pours concrete into the mold cavity 1. After the concrete solidifies, the operator first rotates the turntable 24. The turntable 24 drives the gear 22 to rotate in the rotating sleeve 21, and the gear 22 drives another gear 22 to rotate through the rotating rod 17. When the gear 22 rotates, the gear 22 and the tooth groove 14 are meshed with each other, so that the gear 22 drives the slide rod 15 to move downward in the sliding sleeve 8 through the tooth groove 14, and when the slide rod 15 moves in the sliding sleeve 8, the slide The rod 15 drives the push plate 13 to move in the support frame 2, and when the push plate 13 moves, the sliders 5 fixed on both sides of the push plate 13 slide in the slide grooves 6 opened on the inner wall of the support frame 2, so that the push plate 13 can move stably, and the gap between the push plate 13 and the mold cavity 1 becomes larger, which is convenient for avoiding when the mold cavity 1 is rotated. Then the operator rotates the mold cavity 1, and the mold cavity 1 drives the rotating shaft 4 to rotate in the through holes opened on both sides of the support frame 2, and when the rotating shaft 4 rotates, the rotating shaft 4 rotates in the first extension sleeve 3, increasing the stability of the rotation of the rotating shaft 4, so that when the operator rotates the mold cavity 1, the operator no longer needs to pick up the concrete mold cavity 1 for flipping, thereby improving the convenience of the operator flipping the mold cavity 1. After the mold cavity 1 is flipped, the operator rotates the turntable 24 again, and the turntable 24 and the gear 22 rotate, so that the gear 22 and the tooth groove 14 engage with each other, and the tooth groove 14 drives the push plate 13 to fit the opening of the mold cavity 1 through the slide bar 15, and the push plate 13 supports the solidified concrete sample in the mold cavity 1. Then the operator rotates the turntable 24 again, and the turntable 24 drives the gear 22 to rotate, and the gear 22 drives another gear 22 to rotate through the rotating rod 17, so that the gear 22 and the tooth groove 14 engage with each other, and the gear 22 drives the slide bar 15 to move through the tooth groove 14. When the slide bar 15 moves, the slide bar 15 drives the push plate 13 to move, and after the push plate 13 is removed from the opening of the mold cavity 1, the concrete sample in the mold cavity 1 is moved under the action of gravity.The concrete sample falls off from the mold cavity 1.

[0029] In other embodiments, a baffle is provided inside the mold cavity 1, and a positioning block 25 is welded on one side of the baffle and the mold cavity 1, and the surface of the positioning block 25 is provided with a positioning groove 26 provided on the mold cavity 1. The baffle can be a vertical baffle 12, and the vertical baffle 12 is horizontally arranged in the mold cavity 1. The baffle can be a horizontal baffle 16, and the horizontal baffle 16 is vertically arranged in the mold cavity 1. When the operator makes a complete strip concrete sample, the operator first moves the horizontal baffle 16, and the horizontal baffle 16 drives the positioning block 25 to move, so that the positioning block 25 is inserted into the positioning groove 26. When the positioning block 25 is inserted into the positioning groove 26, the horizontal baffle 16 blocks the At the front end of the positioning groove 26, after the operator pours concrete into the mold cavity 1, the concrete in the mold cavity 1 is a complete strip concrete sample. When the operator needs to make several groups of square concrete blocks, the operator first moves the vertical baffle 12, and the vertical baffle 12 drives the positioning block 25 to move, so that the positioning block 25 and the positioning groove 26 are aligned with each other. Then the operator pushes the vertical baffle 12, and the vertical baffle 12 drives the positioning block 25 to move, and inserts the positioning block 25 into the positioning groove 26, dividing the mold cavity 1 into several groups of rectangular chambers. The operator pours concrete into the mold cavity 1, which is convenient for the operator to prepare several groups of concrete samples at the same time, thereby improving the scope of use of the operator.

[0030] In other embodiments, the turntable 24 passes through one side of the rotating sleeve 21 and the surface of the rotating rod 17 and is provided with a ring 23, and a pull frame 20 is welded on either side of the surface of the ring 23. The middle part of the pull frame 20 is penetrated by a limit rod 19 welded on the outer wall of the sliding sleeve 8, and the surface of the limit rod 19 is wound with a second spring 18 respectively abutting between the inner wall of the pull frame 20 and the surface of the sliding sleeve 8. When the operator quickly resets the push plate 13, the operator first pulls the turntable 24 to move. When the turntable 24 moves, the turntable 24 drives the gear 22 to move in the rotating sleeve 21, and when the gear 22 moves, the gear 22 drives the ring 23 to move through the turntable 24 and the rotating rod 17 at the same time. When the ring 23 moves, the ring 23 pulls the pull frame 20 to the limit rod 19 The surface slides, and when the pull frame 20 slides on the surface of the limit rod 19, the pull frame 20 squeezes the second spring 18, causing the second spring 18 to be elastically deformed. After the second spring 18 is elastically deformed, the second spring 18 avoids the pull frame 20, so that the gear 22 is separated from the tooth groove 14, and when the operator releases the turntable 24, the turntable 24 no longer squeezes the second spring 18 through the collar 23, and the elastic deformation of the second spring 18 is restored. The second spring 18 pushes the pull frame 20 to move, so that the pull frame 20 drives the rotating rod 17 and the tooth groove 14 to move through the collar 23, so that the rotating rod 17 and the tooth groove 14 drive the gear 22 to move, so that the gear 22 moves to the tooth groove 14 again, so that the gear 22 and the tooth groove 14 are meshed again.

[0031] In other embodiments, the sliding sleeve 8 is symmetrically provided with traction grooves 9 welded on the support frame 2, and the traction groove 9 is respectively provided with a first spring 10 and a traction rod 11. The ends of the first spring 10 on both sides are respectively abutted between the inner wall of the traction groove 9 and the surface of the traction rod 11. The traction rod 11 passes through the traction groove 9 and is sleeved with a second extension sleeve 7 welded on the traction groove 9 on one side. The end of the traction rod 11 is welded to the inner wall of the push plate 13. When the operator pulls the turntable 24, the turntable 24 drives the gear 22 to slide in the rotating sleeve 21, and the gear 22 moves away from the tooth groove 14. The gear 22 After the gear 22 and the tooth groove 14 are no longer engaged with each other, the gear 22 and the tooth groove 14 no longer cause the push plate 13 to press the traction rod 11 through the slide bar 15. After the traction rod 11 is no longer squeezed by the first spring 10, after the first spring 10 is elastically deformed, the first spring 10 pushes the traction rod 11 to move, and the traction rod 11 pushes the push plate 13 to move, so that the push plate 13 automatically moves to the surface of the mold cavity 1, which is convenient for quickly resetting the push plate 13. The operator no longer needs to rotate the turntable 24 again. The turntable 24 drives the tooth groove 14 to move the slide bar 15 through the gear 22, and the slide bar 15 drives the push plate 13 to reset.
