Description

Technical Field

[0001] This utility model relates to the field of concrete product manufacturing equipment technology, and in particular to a locking mechanism and a concrete vibration shaping device. Background Technology

[0002] Figure 1 The image shows a concrete vibration shaping device in the prior art. This concrete vibration shaping device includes a base 10, a vibration platform 30, and a vibration motor 40. The vibration platform 30 is mounted on the top of the base 10 by four support springs 20, and the vibration motor 40 is mounted on the bottom of the vibration platform 30. A shaping mold 60 is used to place on the vibration platform 30 during production. At least one locking mechanism 50 is provided on each of the opposite sides of the vibration platform 30. The existing locking mechanism 50 includes a hinge screw 51 and a handwheel 52. The hinge screw 51 is hinged to the hinge seat pivot on the vibration platform 30, and the handwheel 52 is screwed onto the hinge screw 51.

[0003] In use, the molding mold 60 is first placed on the vibration platform 30, and then the pressure rod 70 is placed on the molding mold 60. The pressure rod 70 has longitudinal slots at both ends. The hinge screw 51 is rotated into the slot, and the handwheel 52 is positioned above the pressure rod 70. The handwheel 52 is then tightened, pressing the molding mold 60 onto the vibration platform 30 via the pressure rod 70. Since there are two locking mechanisms 50 on one side, totaling four, the handwheel 52 needs to be repeatedly turned when pressing and removing the molding mold 60, making the operation complex and inefficient. Therefore, our company's technicians designed the locking mechanism and concrete vibration molding device described in this application. Utility Model Content

[0004] The purpose of this invention is to provide a locking mechanism and a concrete vibration shaping device to solve the problem that the locking mechanism of the existing concrete vibration shaping device requires repeated turning of the handwheel, resulting in complicated operation steps and low work efficiency.

[0005] To achieve the above objectives, this utility model provides a locking mechanism, including a fixed base, a slide rod, a hook rod, a pin, a cam, and an operating lever. The fixed base is provided with a slide groove, and the slide rod is slidably installed in the slide groove. The hook rod is installed at the upper end of the slide rod, and a lever is fixedly provided at the lower end of the slide rod. The lever extends away from the fixed base. The cam is hinged to the slide groove of the fixed base by a pin. The protruding end of the cam cooperates with the lever to drive the slide rod to move downward and form a self-locking mechanism with the slide rod. The operating lever is fixedly connected to the cam.

[0006] The hook rod and the slide rod are rotatably connected.

[0007] A limiting post is fixedly provided at the top of the slide rod, and a limiting component is fixedly provided at the upper end of the limiting post. A connecting sleeve is provided at one end of the hook rod relative to the hook end, and the connecting sleeve is rotatably installed on the limiting post between the slide rod and the limiting component.

[0008] A lifting spring is installed between the slide rod and the fixed base, and the lifting spring is used to push the slide rod to move upward.

[0009] A support is fixedly installed in the sliding groove of the fixed seat, and an installation groove is provided on the sliding rod. The support extends into the installation groove, and the lifting spring is installed in the installation groove. The upper end of the lifting spring abuts against the sliding rod, and the lower end abuts against the support.

[0010] The upper end of the mounting groove is fixed with a first positioning post, and the support is provided with a second positioning post. The upper end of the lifting spring is fitted outside the first positioning post, and the lower end is fitted outside the second positioning post.

[0011] The support is provided with a threaded hole, and the second positioning post is a screw, which is screwed into the threaded hole for fixation.

[0012] The fixed seat has protruding ear plates on the two side walls of the slide groove, and the ear plates are provided with a first hinge hole. The cam is provided with a second hinge hole. The cam is located between the two ear plates, and the pin passes through the first hinge hole and the second hinge hole.

[0013] The upper side of the lever is provided with a guide surface, which is used to cooperate with the protruding end of the cam to drive the slide rod to move downward.

[0014] A concrete vibration shaping device includes a base, a vibration platform, and a vibration motor. The vibration platform is mounted on top of the base by multiple support springs, and the vibration motor is mounted on the bottom of the vibration platform. A shaping mold is placed on the vibration platform during production. At least two opposite sides of the vibration platform are respectively equipped with a locking mechanism, and the shaping mold is fixed with a limiting structure for hooking.

[0015] Compared with the prior art, this utility model has the following technical effects:

[0016] 1. This utility model drives the operating lever to rotate the cam. When the cam's protruding end is away from the fixed seat, as shown in the figure, the slide rod is in an active state. When the cam's protruding end is close to the fixed seat, the cam's protruding end abuts against the angle between the slide rod and the lever. Since the cam's rotation center is away from the slide rod, the protruding end forms a self-locking mechanism at the angle between the slide rod and the lever, thereby restricting the slide rod from moving upward.

[0017] 2. The hook rod and slide rod of this utility model are rotatably connected, which eliminates the interference of the hook rod on the molding mold when the molding mold is removed.

[0018] 3. In this invention, a lifting spring is installed between the slide rod and the fixed base. When the operating lever is rotated counterclockwise, the protruding end of the cam gradually moves away from the slide rod. At this time, the compressed lifting spring lifts the slide rod, thereby causing the slide rod to rise automatically.

[0019] 4. By installing the locking mechanism of this application on the vibration platform, this utility model solves the problem that the locking mechanism of the existing concrete vibration shaping device requires repeated turning of the handwheel, resulting in complicated operation steps and low work efficiency. The operation steps are simpler and the work efficiency is improved. Attached Figure Description

[0040] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0041] Example 1:

[0042] Please see Figure 3-9 A locking mechanism 50 includes a fixed base 54, a slide rod 55, a hook rod 56, a pin 57, a cam 58, and an operating lever 59. The fixed base 54 is provided with a slide groove 541. The slide rod 55 is slidably installed in the slide groove 541. The hook rod 56 is installed at the upper end of the slide rod 55. The lower end of the slide rod 55 is fixedly provided with a lever 551. The lever 551 extends away from the fixed base 54. The cam 58 is hinged in the slide groove 541 of the fixed base 54 through the pin 57. The protruding end 582 of the cam 58 cooperates with the lever 551 to drive the slide rod 55 to move downward and can form a self-locking mechanism with the slide rod 55. The operating lever 59 is fixedly connected to the cam 58.

[0043] By driving the operating lever 59, the cam 58 is rotated. When the protruding end 582 of the cam 58 moves away from the fixed seat 54, as... Figure 9 As shown, slide bar 55 is in an active state; when the protruding end 582 of cam 58 approaches the fixed seat 54, see... Figure 4The protruding end 582 of the cam 58 abuts against the angle between the slide rod 55 and the lever 551. Since the rotation center of the cam 58 is far away from the slide rod 55, the protruding end 582 forms a self-locking at the angle between the slide rod 55 and the lever 551, thereby restricting the slide rod 55 from moving upward.

[0044] In this embodiment, see Figure 5 The fixing base 54 has protruding ear plates 542 on each of the two side walls of the slide groove 541, and the ear plates 542 are provided with first hinge holes 543. See Figure 7 The cam 58 is provided with a second hinge hole 581. The cam 58 is located between two ear plates 542. The pin 57 passes through the first hinge hole 543 and the second hinge hole 581.

[0045] Example 2:

[0046] Based on Example 1, the hook rod 56 and the slide rod 55 are rotatably connected, eliminating the interference of the hook rod 56 on the molding mold 60 when the molding mold 60 is removed.

[0047] Specifically, see Figure 3 , 4 6, 8, A limiting post 553 is fixedly provided at the top of the slide rod 55, and a limiting member 554 is fixedly provided at the upper end of the limiting post 553. A connecting sleeve 562 is provided at one end of the hook rod 56 relative to the hook end 561. The connecting sleeve 562 is rotatably installed on the limiting post 553 between the slide rod 55 and the limiting member 554.

[0048] In this embodiment, the limiting member 554 is a ring structure and is welded to the limiting post 553.

[0049] Example 3:

[0050] Based on Embodiment 1 or Embodiment 2, a lifting spring 557 is installed between the slide rod 55 and the fixed base 54. The lifting spring 557 is used to push the slide rod 55 to move upward.

[0051] After the lifting spring 557 is installed between the slide bar 55 and the fixed base 54, see Figure 4 When the operating lever 59 is rotated counterclockwise, the protruding end 582 of the cam 58 gradually moves away from the slide rod 55. At this time, the compressed lifting spring 557 lifts the slide rod 55, thereby causing the slide rod 55 to rise automatically. Figure 9 As shown.

[0052] Specifically, see Figure 5 , 6A support 544 is fixedly installed in the slide groove 541 of the fixed base 54. An installation groove 555 is provided on the slide rod 55. The support 544 extends into the installation groove 555. The lifting spring 557 is installed in the installation groove 555. The upper end of the lifting spring 557 abuts against the slide rod 55, and the lower end abuts against the support 544.

[0053] Furthermore, a first positioning post 556 is fixedly mounted on the upper end of the mounting slot 555, and a second positioning post 546 is provided on the support 544. The upper end of the lifting spring 557 is fitted outside the first positioning post 556, and the lower end is fitted outside the second positioning post 546. By setting the first positioning post 556 and the second positioning post 546, the lifting spring 557 can be restrained, preventing it from falling off during use.

[0054] In this embodiment, see Figure 4 The support 544 is provided with a threaded hole 545, and the second positioning post 546 is a screw, which is screwed to the threaded hole 545 for fixation.

[0055] Example 4:

[0056] Based on Embodiment 1, Embodiment 2, or Embodiment 3, in order to ensure smooth engagement between the cam 58 and the lever 551, see [reference needed]. Figure 3 , 6 9. A guide surface 552 is provided on the upper side of the paddle block 551. The guide surface 552 is used to cooperate with the protruding end 582 of the cam 58 to drive the slide rod 55 to move downward.

[0057] In this embodiment, the guide surface 552 is an inclined surface. Of course, the guide surface 552 can also be a curved surface.

[0058] Example 5:

[0059] Based on Example 1, Example 2, Example 3, or Example 4, see [link to example]. Figure 2 , 10 A concrete vibration shaping device includes a base 10, a vibration platform 30, and a vibration motor 40. The vibration platform 30 is mounted on top of the base 10 via multiple support springs 20, and the vibration motor 40 is mounted on the bottom of the vibration platform 30. A shaping mold 60 is placed on the vibration platform 30 during production. A locking mechanism 50 is mounted on at least two opposite sides of the vibration platform 30, and a limiting structure 61 for hooking a hook rod 56 is fixed on the shaping mold 60. This solves the problem that the locking mechanism of existing concrete vibration shaping devices requires repeated turning of the handwheel, resulting in complex operation steps and low work efficiency.

[0060] In this embodiment, two locking mechanisms 50 are respectively installed on opposite sides of the vibration platform 30. Of course, at least one locking mechanism 50 can also be installed around the perimeter of the vibration platform 30.

[0061] In this embodiment, the limiting structure 61 can be a stop block welded to the upper periphery of the molding mold 60, or it can be a groove provided on the upper periphery of the molding mold 60.

[0062] The working principle or operation process of this utility model is as follows:

[0063] When using, please refer to Figure 2 First, place the molding mold 60 onto the vibration platform 30, then adjust the hook end 561 of the hook rod 56 to the position above the limiting structure 61. See [link / reference]. Figure 4 Rotate the operating lever 59 clockwise to rotate the cam 58. During this process, the slide bar 55 moves down, the lifting spring 557 is compressed, and the hook bar 56 undergoes elastic deformation after abutting against the molding die 60. This causes the protruding end 582 of the cam 58 to abut against the angle between the slide bar 55 and the lever 551. Since the rotation center of the cam 58 is far from the slide bar 55, the protruding end 582 forms a self-locking mechanism at the angle between the slide bar 55 and the lever 551, thereby restricting the slide bar 55 from moving upward and fixing the molding die 60 onto the vibration platform 30.

[0064] When the molding mold 60 is removed, and the operating lever 59 is rotated counterclockwise, the protruding end 582 of the cam 58 gradually moves away from the slide rod 55. At this time, the compressed lifting spring 557 lifts the slide rod 55, thereby causing the slide rod 55 to rise automatically. Figure 9 As shown.

[0065] Then, by rotating the hook rod 56, the molding mold 60 can be removed from the vibrating platform 30. The operation is simpler and the work efficiency is improved.
