Description

Technical Field

[0001] The utility model relates to the technical field of parallel clamps, in particular to a decompression type parallel clamp for a grain bin pressure groove pipe. Background Technique

[0002] In the construction of grain bins, the pressure groove pipe is one of the important components used for the sealing of grain bins. Through this design, it can effectively prevent the grain from getting damp or being affected by other external factors during storage. During the installation and fixation of the pressure groove pipe, the decompression type parallel clamp plays its clamping function. The decompression type parallel clamp usually adopts the classic "angle fixation" design, which can effectively prevent the workpiece from floating under the action of the clamping force. Its "tightening" type jaw design can reduce jaw deformation. By rotating the lead screw, the movement of the movable jaw body is driven, so as to clamp or loosen the clamped workpiece. This design enables the operator to conveniently control the clamping force.

[0003] At present, during the use of the parallel clamp, since it is necessary to drive the movement of the jaw body by rotating the lead screw, at this time, the staff needs to borrow other tools such as a wrench to rotate the lead screw. At the same time, when clamping the pressure groove pipe, due to the different shapes of the pressure groove pipes, in order to ensure the stable clamping of the pressure groove pipe, it is necessary to replace the jaw body that fits the pressure groove pipe better. However, since the installation of the traditional jaw body is fixed by screws, tools are required for disassembly and replacement, which will increase the working hours. Therefore, it is necessary to provide a decompression type parallel clamp for a grain bin pressure groove pipe. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a decompression type parallel clamp for a grain bin pressure groove pipe to solve the current technical problems that the staff needs to borrow other tools such as a wrench to rotate the lead screw, and at the same time, when clamping the pressure groove pipe, due to the different shapes of the pressure groove pipes, in order to ensure the stable clamping of the pressure groove pipe, it is necessary to replace the jaw body that fits the pressure groove pipe better. However, since the installation of the traditional jaw body is fixed by screws, tools are required for disassembly and replacement, which will increase the working hours.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A decompression type parallel clamp for a grain bin pressure groove pipe includes a bottom plate, a fixed clamp block fixedly connected to the bottom plate, a movable clamp block arranged on the bottom plate, a threaded rod installed on the bottom plate, and a force application rod arranged on the threaded rod.

[0007] As a preferred technical solution of the utility model, the movable clamp block includes a mounting seat movably connected to the threaded rod, a plug hole opened on the mounting seat, a cushion block arranged on the mounting seat, and a limiting hole opened on the cushion block.

[0008] As a preferred technical solution of the present utility model, a locking member is provided in the insertion hole, and two locking members are symmetrically arranged in the insertion hole, and an unlocking member is provided on the mounting seat.

[0009] As a preferred technical solution of the present utility model, the locking member includes a fixing ring, a locking column disposed in the fixing ring, a limiting plate fixed to one end of the locking column, and an inclined surface formed at the other end of the locking column.

[0010] As a preferred technical solution of the present utility model, the locking member further includes a compression spring sleeved on the locking column, and a reset plate fixed to the locking column.

[0011] As a preferred technical solution of the present utility model, the unlocking member includes a push-pull hole, a push-pull plate disposed in the push-pull hole, and the push-pull plate is in a T shape.

[0012] As a preferred technical solution of the present utility model, the unlocking member further includes an arc-shaped groove formed in the push-pull hole, and a limiting block fixed to the push-pull plate.

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

[0014] In the present utility model, a force application rod is installed at one end of the threaded rod. The force application rod can rotate on the threaded rod. When the force application rod rotates to a state perpendicular to the threaded rod, then the staff can drive the threaded rod to rotate by rotating the force application rod. In this way, the threaded rod can be rotated without borrowing tools. At the same time, the working intensity of the staff can be reduced through the force application rod, and the staff can easily rotate the threaded rod through the force application rod.

[0015] In the present utility model, a locking member is provided on the mounting seat. The cushion block and the mounting seat are connected through the locking member. When one side of the cushion block is inserted into the insertion hole, both sides of the cushion block will squeeze the locking column, and the locking column will be inserted into the limiting hole, and then the locking column will be stuck in the limiting hole. At this time, the cushion block can be fixed on the mounting seat under the action of the locking column. In this way, fixing can be carried out without using screws, and at the same time, the installation speed will be increased.

[0016] In the present utility model, an unlocking member is installed on the top of the mounting base. Since the spacer block and the mounting are connected and fixed through a locking member, in order to improve the replacement efficiency, a push-pull plate is slidably connected to the mounting base. When the push-pull plate is pushed, the bottom end of the push-pull plate will contact the reset plate, and then the push-pull plate will push the reset plate to move during the movement. Since the reset plate is fixed on the locking column, the locking column will move out of the limiting hole, thereby releasing the connection between the spacer block and the mounting base. After quickly disassembling the spacer block, a spacer block that fits the grooved pipe better can be quickly replaced, so as to ensure the stable clamping of the grooved pipe.

[0017] Other advantages, objectives, and features of the present utility model will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model. The objectives and other advantages of the present utility model can be realized and obtained through the following specification. Brief Description of the Drawings

[0028] Embodiment 1

[0029] Please refer to Figure 1-2, a technical solution provided by the present utility model: A decompression type flat mouth pliers for a grain bin pressure groove pipe, comprising a bottom plate 1, characterized in that: a fixed clamping block 2 is fixedly connected to the bottom plate 1, the fixed clamping block 2 is fixed at one end of the top of the bottom plate 1, a movable clamping block 3 is provided on the bottom plate 1, the movable clamping block 3 is slidably connected to the top of the bottom plate 1, and the workpiece can be clamped by the fixed clamping block 2 and the movable clamping block 3. A threaded rod 4 is installed on the bottom plate 1, the threaded rod 4 is installed inside the bottom plate 1, and a force application rod 5 is provided on the threaded rod 4. The force application rod 5 is rotatably connected to one end of the threaded rod 4 through a pin. When the force application rod 5 is perpendicular to the threaded rod 4, the staff can easily rotate the threaded rod 4 by means of the force application rod 5.

[0030] Specifically, the present utility model installs a fixed clamping block 2 and a movable clamping block 3 on the bottom plate 1. The movable clamping block 3 can slide on the bottom plate 1. Place the grain bin pressure groove pipe between the fixed clamping block 2 and the movable clamping block 3, and then adjust the distance between the fixed clamping block 2 and the movable clamping block 3 by moving the movable clamping block 3, so as to realize the clamping of the grain bin pressure groove pipe. The force application rod 5 can rotate on the threaded rod 4. When the force application rod 5 rotates to a state perpendicular to the threaded rod 4, then the staff can drive the threaded rod 4 to rotate by rotating the force application rod 5. In this way, the threaded rod 4 can be rotated without using tools, and at the same time, the working intensity of the staff can be reduced through the force application rod 5. The staff can easily rotate the threaded rod 4 through the force application rod 5, so that the grain bin pressure groove pipe can be easily clamped and fixed in daily work.

[0031] The movable clamping block 3 includes a mounting seat 301 movably connected to the threaded rod 4. The mounting seat 301 is threadedly connected to the threaded rod 4. In this way, when the threaded rod 4 rotates, it can drive the mounting seat 301 to move. A plug hole 302 is opened on the mounting seat 301. The plug hole 302 is rectangular in shape. The plug hole 302 is opened on the surface of the mounting seat 301 connected to the cushion block 303. A cushion block 303 is provided on the mounting seat 301. The cushion block 303 is connected to the mounting seat 301. Through the cushion block 303, it can fit more closely with the grain bin pressure groove pipe, thereby improving the stability of the grain bin pressure groove pipe, and a limiting hole 304 is opened on the cushion block 303. Two limiting holes 304 are opened, and the two limiting holes 304 are respectively opened on one side of the cushion block 303.

[0032] A locking member 6 is provided in the plug hole 302, and two locking members 6 are symmetrically arranged in the plug hole 302, and an unlocking member 7 is provided on the mounting seat 301.

[0033] Specifically, in the present utility model, a locking member 6 is provided on the mounting base 301, and the spacer block 303 is connected to the mounting base 301 through the locking member 6. When one side of the spacer block 303 is inserted into the insertion hole 302, both sides of the spacer block 303 will squeeze the locking post 602, and the locking post 602 will be inserted into the limiting hole 304, and then the locking post 602 will be stuck in the limiting hole 304. At this time, the spacer block 303 can be fixed on the mounting base 301 under the action of the locking post 602. In this way, it is not necessary to use screws for fixing, and at the same time, the installation speed will be increased.

[0034] Embodiment 2

[0035] Please refer to Figure 1-4 , which is another technical solution provided by the present utility model. This embodiment has the same parts as the above Embodiment 1, and the same parts will not be described again in this embodiment. The specific differences are as follows:

[0036] A pressure-reducing flat-jaw pliers for a grain bin grooved pipe includes a locking member 6 including a fixing ring 601. The fixing ring 601 is fixedly connected inside the mounting base 301, and there are two fixing rings 601. A locking post 602 is arranged inside the fixing ring 601. The locking post 602 is movably connected inside the two fixing rings 601. A limiting plate 603 fixed to one end of the locking post 602 can prevent the locking post 602 from disengaging from the fixing ring 601. An inclined surface 604 is opened at the other end of the locking post 602. Through the inclined surface 604, when the spacer block 303 is inserted into the insertion hole 302, it can more easily squeeze the locking post 602 to move inside the fixing ring 601.

[0037] The locking member 6 further includes a compression spring sleeved on the locking post 602. The compression spring is sleeved between the reset plate 606 and the fixing ring 601. Through the compression spring, the locking post 602 can automatically reset after being squeezed by the spacer block 303, and a reset plate 606 fixed on the locking post 602.

[0038] Specifically, when the spacer block 303 is inserted into the insertion hole 302 on the mounting base 301 in the present utility model, the spacer block 303 will squeeze the locking post 602. When the locking post 602 contacts the limiting hole 304 on the spacer block 303, the locking post 602 will be inserted into the limiting hole 304, so that the spacer block 303 can be quickly fixed on the mounting base 301.

[0039] The unlocking member 7 includes a push-pull hole 701 opened at the top of the mounting base 301, a push-pull plate 702 arranged in the push-pull hole 701, and the push-pull plate 702 is in a T shape and is slidably connected in the push-pull hole 701.

[0040] The unlocking member 7 further includes an arc-shaped groove 703 formed in the pushing and pulling hole 701. The arc-shaped groove 703 is formed on the inner wall of the pushing and pulling hole 701, and a limiting block 704 fixed on the pushing and pulling plate 702. The limiting block 704 is fixed on the surface of the pushing and pulling plate 702 in contact with the inner wall of the pushing and pulling hole 701.

[0041] Specifically, in the present utility model, an unlocking member 7 is installed on the top of the mounting seat 301. Since the cushion block 303 and the mounting are connected and fixed by the locking member 6, in order to improve the replacement efficiency, a pushing and pulling plate 702 is slidably connected to the mounting seat 301. When the pushing and pulling plate 702 is pushed, the bottom end of the pushing and pulling plate 702 will contact the reset plate 606, and then the pushing and pulling plate 702 will push the reset plate 606 to move during the movement. Since the reset plate 606 is fixed on the locking column 602, the locking column 602 will move out of the limiting hole 304, thereby releasing the connection between the cushion block 303 and the mounting seat 301, quickly disassembling the cushion block 303, and quickly replacing the cushion block 303 that fits the grooved pipe better, so as to ensure the stable clamping of the grooved pipe of the granary.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
