Description

Technical Field

[0001] The utility model relates to the technical field of agricultural greenhouse construction, in particular to a steel pipe pressure mechanism for agricultural greenhouse construction. Background Art

[0002] The composition of the greenhouse is to use bamboo poles, cement poles, light steel pipes or pipes and other materials as the skeleton, to make columns, pull rods, arch rods and pressure rods, and cover them with plastic film to become an arched material shed.

[0003] Currently, when constructing agricultural greenhouses, most construction workers use a steel pipe pressure mechanism to assist builders in inserting the steel pipe into the soil. Existing steel pipe pressure mechanisms typically first clamp the steel pipe using a clamping structure on the steel pipe pressure mechanism. Then, a lifting structure on the steel pipe pressure mechanism applies downward pressure to the clamped steel pipe, causing the steel pipe to be inserted into the soil. For example, Chinese Patent Publication No. CN113565094A discloses an auxiliary device for constructing agricultural greenhouses. However, because the clamping and lifting structures on the steel pipe pressure mechanism require separate operation by the builders, the use of the steel pipe pressure mechanism is relatively cumbersome and inconvenient. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art, such as: the existing steel pipe pressure mechanism usually first clamps the steel pipe through the clamping structure on the steel pipe pressure mechanism, and then applies downward pressure to the clamped steel pipe through the lifting structure on the steel pipe pressure mechanism, and inserts the steel pipe into the soil. However, since the clamping structure and the lifting structure on the steel pipe pressure mechanism need to be operated separately by the construction personnel, the use steps of the steel pipe pressure mechanism are relatively cumbersome, and the steel pipe pressure mechanism is more troublesome to use. A steel pipe pressure mechanism for building an agricultural greenhouse is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] Example 1:

[0028] Reference Figure 1-9 A steel pipe pressure mechanism for building an agricultural greenhouse includes a base plate 1, a lifting bracket 2 is fixedly connected to the upper surface of the base plate 1, a first rectangular tube 3 is fixedly connected to the left side of the lifting bracket 2, a strip ring 4 is fixedly connected to the left side of the first rectangular tube 3, a first strip hole 5 is opened on the left side of the first rectangular tube 3, a clamping bracket 6 is fitted on the left side of the first rectangular tube 3, the inner wall of the strip ring 4 and the inner wall of the first strip hole 5, a guide bracket 7 is fitted on the surface of the clamping bracket 6 and the inner wall of the first rectangular tube 3, and the bottom of the guide bracket 7 is fixedly connected to the upper surface of the base plate 1.

[0029] The lifting bracket 2 includes a first hollow block 201, the bottom of the first hollow block 201 is fixedly connected to the upper surface of the base plate 1, the inner wall of the first hollow block 201 is fixedly connected to the bearing 202, the inner wall of the bearing 202 is fixedly connected to the first threaded column 203, the surface of the first threaded column 203 is threadedly connected to the first threaded cylinder 204, the surface of the first threaded cylinder 204 and the right side of the first rectangular cylinder 3 are fixedly connected to the second hollow block 205, the top of the first threaded column 203 is fixedly connected to the turntable 206, when the user rotates the turntable 206, the first rectangular cylinder 3 moves upward or downward through the cooperation of the first threaded column 203 and the first threaded cylinder 204.

[0030] The clamping bracket 6 includes a hollow square column 601, and a rubber pad 602 is bonded to one side of the hollow square column 601. The inner wall of the strip ring 4 and the left side of the first rectangular tube 3 are in contact with the surface of the hollow square column 601. The strip ring 4 prevents the hollow square column 601 from rotating when moving back and forth. The inner wall of the hollow square column 601 is fixedly connected with a second threaded column 603. The inner wall of the first strip hole 5 and the inner wall of the guide bracket 7 are in contact with the surface of the second threaded column 603. The surface of the second threaded column 603 is threadedly connected with a nut 604. The nut 604 is located in the first rectangular tube 3. The second threaded column 603 can move back and forth in the first strip hole 5. At the same time, when the nut 604 is screwed on the second threaded column 603, the nut 604 prevents the second threaded column 603 from being separated from the first strip hole 5.

[0031] The guide bracket 7 includes a vertical plate 701, and a guide hole 702 is opened inside the vertical plate 701. The inner wall of the guide hole 702 contacts the surface of the second threaded column 603. The guide hole 702 is composed of two inclined holes and one vertical hole. When the clamping bracket 6 moves from top to bottom, the guide hole 702 is used to clamp the steel pipe first, and a downward force is applied to the clamped steel pipe. At the same time, when the steel pipe is inserted to the specified depth, the clamping bracket 6 can automatically loosen the steel pipe.

[0032] A first threaded hole 703 is provided inside the vertical plate 701, and a second rectangular tube 704 is fitted on the front and back sides of the vertical plate 701. A second strip hole 705 is provided on the left and right sides of the second rectangular tube 704. A first bolt 706 is fitted on the inner wall of the second strip hole 705. The surface of the first bolt 706 is threadedly connected to the inner wall of the first threaded hole 703. Rubber rings 707 are fitted on the surface of the first bolt 706 and the left and right sides of the second rectangular tube 704. Through the cooperation between the first bolt 706 and the first threaded hole 703, the first bolt 706 can tighten or loosen the rubber ring 707.

[0033] When the first bolt 706 presses the rubber ring 707, the friction between the rubber ring 707 and the second rectangular tube 704 prevents the position of the vertical plate 701 from changing. When the first bolt 706 loosens the rubber ring 707, the position of the vertical plate 701 in the second rectangular tube 704 can be freely adjusted. Therefore, when the user uses the steel pipe pressure mechanism, the minimum distance between the front and rear clamping brackets 6 can be changed by adjusting the distance between the front and rear vertical plates 701, so that the steel pipe pressure mechanism can be applied to steel pipes of different thicknesses.

[0034] Example 2:

[0035] Reference Figure 1-4The bottom of the base plate 1 is fixedly connected to a mounting bracket 8, a circular hole 9 is opened inside the base plate 1, and a second bolt 10 is fitted on the inner wall of the circular hole 9. The surface of the second bolt 10 is threadedly connected to a second threaded cylinder 11, and the upper surface of the second threaded cylinder 11 contacts the bottom of the base plate 1, and the inner wall of the second threaded cylinder 11 is fixedly connected to a ground nail 12. Through the cooperation of the second bolt 10 and the second threaded cylinder 11, the ground nail 12 and the base plate 1 are disassembled and assembled, so that the user can replace the damaged ground nail 12. The bottom of the mounting bracket 8 is fixedly connected to a universal wheel 13, and the bottom of the universal wheel 13 and the bottom of the second threaded cylinder 11 are in the same horizontal plane.

[0036] By providing a universal wheel 13 at the bottom of the base plate 1, the steel pipe pressure mechanism is more convenient to move. At the same time, when the steel pipe pressure mechanism is moved to the specified position, by inserting the ground nails 12 into the ground, the steel pipe pressure mechanism will not move when the user rotates the turntable 206 on the lifting bracket 2, thereby improving the stability of the steel pipe pressure mechanism during use.

[0037] In the present invention, when the user uses the steel pipe pressure mechanism, he first pushes the steel pipe pressure mechanism to a suitable position through the universal wheel 13, and places the steel pipe between the front and rear clamping brackets 6. Then, he inserts the ground nail 12 into the soil and steps on the base plate 1 with his feet. Then, by rotating the turntable 206, the first threaded column 203 is rotated, and the first rectangular tube 3 is moved downward through the cooperation of the first threaded column 203 and the first threaded tube 204. At this time, the rubber pad 602 on the clamping bracket 6 can clamp the steel pipe through the cooperation of the inclined hole above the guide hole 702 and the second threaded column 603.

[0038] Then, through the cooperation between the vertical hole in the middle of the guide hole 702 and the second threaded column 603, the clamping bracket 6 can always clamp the steel pipe when moving downward, and through the friction between the steel pipe and the rubber pad 602, the clamping bracket 6 can apply a downward force to the steel pipe. At this time, the steel pipe can be inserted into the soil. When the second threaded column 603 moves down to the inclined hole below the guide hole 702, through the cooperation between the guide hole 702 and the second threaded column 603, the clamping bracket 6 can automatically loosen the steel pipe, and the steel pipe pressure mechanism can be directly removed.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
