Description

Technical Field

[0001] The utility model belongs to the technical field of field tools, in particular to an engineering shovel for geological field survey. Background Art

[0002] Geological surveys are generally conducted in the field, and an engineer shovel can solve various problems encountered in the field. However, the structural design of existing engineer shovels is not rational enough, the shape is rigid and not novel and unique enough, the function is relatively simple, and it is not convenient to carry. In addition, in some special cases, the blade of the engineer shovel cannot achieve a multi-angle working state, which is not conducive to the operation of the blade and brings inconvenience to people.

[0003] At present, the China Patent Network discloses a multi-purpose military shovel [Authorization Announcement No.: CN219275754U], which includes a shovel head and a handle. The shovel head includes a shovel head body, and the upper end of the shovel head body is fixedly connected to a threaded connecting column. The handle includes a first handle rod, a second handle rod, a third handle rod and a plug. The lower end of the first handle rod is fixedly connected to a first connecting seat, and a first threaded hole is horizontally opened in the first connecting seat. The lower end of the first connecting seat is fixedly connected to a second connecting seat, and a second thread is vertically opened in the second connecting seat. When the threaded connecting column is screwed into the first threaded hole, the shovel head is connected to the handle. The shovel head and the handle are arranged vertically, and can be used as a hoe. When the threaded connecting column is screwed into the second threaded hole, the shovel head is connected to the handle. The shovel head and the handle are located in a straight line and can be used as a shovel.

[0004] The above-mentioned military shovel has the following defects: during the angle adjustment operation of the shovel head, it is necessary to first disassemble the handle and the shovel head, and then connect the handle to the first threaded hole or the second threaded hole, which makes the angle adjustment of the shovel head very cumbersome. Moreover, when the shovel head and the handle are set vertically, the shovel head is used as a hoe. At this time, the stress is concentrated at the connection between the threaded connecting column and the first connecting seat. The threaded connecting column is prone to deformation, resulting in the handle and the shovel head being unable to be disassembled and separated. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose an engineer shovel for geological field survey. The technical problem to be solved by the utility model is: how to solve the convenience of adjusting the angle of the shovel head.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] An engineer shovel for geological field surveys includes a shovel head, a handle and a mounting column. The shovel head has a mounting frame and is characterized in that the mounting frame includes a threaded column and a connecting head, one end of the threaded column is screwed into one end of the handle, the connecting head is located in the mounting frame and the connecting head and the mounting frame are hinged via a hinge shaft, a positioning sleeve is screwed onto the threaded column, and the mounting frame has a horizontal limit surface and a vertical limit surface, and the positioning sleeve can abut against the horizontal limit surface or the vertical limit surface.

[0008] The shovel head of this structure is hinged to the mounting post by an articulated shaft, and the shovel head can rotate. The positioning sleeve is screwed on the threaded post, and rotating the positioning sleeve can realize the axial movement of the positioning sleeve along the threaded post. When the positioning sleeve abuts against the horizontal limit surface, the positioning sleeve presses the mounting bracket into position, and the mounting bracket cannot rotate, thereby realizing the positioning of the shovel head. At this time, the shovel head and the handle are in the same straight line; when it is necessary to adjust the angle of the shovel head, the positioning sleeve is rotated to make the positioning sleeve gradually move away from the horizontal limit surface. After the positioning sleeve moves a certain stroke, the shovel head is rotated 90°. At this time, the vertical limit surface is horizontal, and then the positioning sleeve is rotated again to make the positioning sleeve pressed against the vertical limit surface. The positioning sleeve presses the mounting bracket into position, and the mounting bracket cannot rotate, thereby realizing the positioning of the shovel head. At this time, the shovel head is perpendicular to the handle. When adjusting the angle of the shovel head, this structure does not require the handle and the shovel head to be disassembled, which greatly improves the convenience of the shovel head angle adjustment operation and saves time and effort. At the same time, when the shovel head is perpendicular to the handle, the shovel head is used as a hoe. At this time, the stress is concentrated on the hinge position of the mounting frame and the connecting head, which will not affect the structure of the positioning sleeve and will not affect the shovel head angle adjustment.

[0009] In the aforementioned engineer shovel for geological field exploration, the mounting frame includes a base plate, with side plates disposed on both left and right sides of the base plate. The connector is located between the two side plates, with a spacing between the connector and the base plate. The upper ends of the side plates have the horizontal limit surfaces, and the front ends of the side plates have the vertical limit surfaces. This structural mounting frame arrangement ensures that the mounting frame can rotate smoothly on the connector.

[0010] In the aforementioned engineer shovel for geological field exploration, the upper end of the locating sleeve is mounted on the outer circumference of the handle, and the inner circumference of the lower end of the locating sleeve has an annular connecting boss, which is threadedly connected to the threaded column. When the locating sleeve rotates, the upper end of the locating sleeve is mounted on the outer circumference of the handle, guiding the rotation and movement of the locating sleeve, ensuring that the locating sleeve does not shift and that the movement of the locating sleeve is stable.

[0011] In the aforementioned engineer shovel for geological field exploration, the outer circumference of the lower portion of the positioning sleeve is provided with an annular gripping boss. The outer circumference of the gripping boss is provided with strip-shaped holes along the axial direction of the positioning sleeve. A plurality of these strip-shaped holes are provided, and all of the strip-shaped holes are spaced apart along the circumference of the positioning sleeve. The provision of the gripping boss increases the outer diameter of the positioning sleeve, making it easier to grasp and, in turn, to apply force to the positioning sleeve. The provision of the strip-shaped holes creates an uneven structure on the outer circumference of the gripping boss, increasing friction with the palm of the hand and further enhancing the ease of rotating the positioning sleeve.

[0012] In the aforementioned engineer shovel for geological field surveys, a compression pad, sleeved on the threaded column, is provided between the connector and the positioning sleeve. The compression pad is made of rubber and can abut against a horizontal or vertical limiting surface. The rubber compression pad has a certain degree of elasticity, and the positioning sleeve uses the compression pad to press the mounting frame into position. When the positioning sleeve is pressed against the compression pad, the compression pad undergoes a certain degree of elastic deformation. The force of this elastic deformation acts on the positioning sleeve and the mounting frame, respectively, making the threaded connection between the positioning sleeve and the threaded column less likely to loosen, thereby ensuring that the mounting frame has a good positioning effect.

[0013] In the aforementioned engineer shovel for geological field exploration, an annular positioning groove is defined on the outer circumference of the lower end of the positioning sleeve. The outer edge of the pressure pad has an annular mounting ring, and the inner wall of the mounting ring has an annular engaging protrusion, which is embedded in the positioning groove. This structure facilitates the installation of the pressure pad on the positioning sleeve. When the positioning sleeve rotates, the pressure pad rotates and moves synchronously with the positioning sleeve, thus avoiding interference with the angle adjustment of the shovel head.

[0014] Compared with the prior art, the engineer shovel for geological field survey of the present invention has the following advantages: when adjusting the angle of the shovel head, there is no need to disassemble the handle and the shovel head, which greatly improves the convenience of the shovel head angle adjustment operation and saves time and effort. At the same time, when the shovel head is perpendicular to the handle, the shovel head is used as a hoe. At this time, the stress is concentrated at the hinge position of the mounting frame and the connecting head, which will not affect the structure of the positioning sleeve, and will not affect the shovel head angle adjustment.

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figures 1 to 4As shown, an engineer shovel for geological field surveys includes a shovel head 1, a handle 2, and a mounting post 3. The shovel head 1 has a mounting frame 10. The mounting post 3 includes a threaded post 30 and a connector 31. One end of the threaded post 30 is screwed into one end of the handle 2. The connector 31 is located in the mounting frame 10 and is hinged to the mounting frame 10 via a hinge shaft 4. A positioning sleeve 5 is screwed onto the threaded post 30. The mounting frame 10 has a horizontal limit surface 6 and a vertical limit surface 7. The positioning sleeve 5 can abut against the horizontal limit surface 6 or the vertical limit surface 7. In this embodiment, the mounting frame 10 includes a base plate 100. Side plates 101 are provided on both the left and right sides of the base plate 100. The connector 31 is located between the two side plates 101. There is a gap between the connector 31 and the base plate 100. The upper end of the side plate 101 has a horizontal limit surface 6, and the front end of the side plate 101 has a vertical limit surface 7. When the shovel head 1 is in the same straight line as the handle 2, the shovel head 1 is located in the vertical direction, and the shovel head 1 is located in the vertical direction, so that the shovel head 1 is located in the vertical direction, and the shovel head 1 is located in the vertical direction, so that the shovel head 1 is located in the vertical direction, and the shovel head 1 is located in the vertical direction, so that the shovel head 1 is located in the vertical direction, and the shovel head 1 is located in the vertical direction, so that the shovel head 1 is located in the vertical direction, and the shovel head 1 is located in the vertical direction, so that the shovel head 1 is located in the vertical direction, and the shovel head 1 is located in the vertical direction, During the process of adjusting the angle of the shovel head 1, this structure does not require the handle 2 to be disassembled from the shovel head 1, which greatly improves the convenience of the angle adjustment operation of the shovel head 1 and saves time and effort. At the same time, when the shovel head 1 is perpendicular to the handle 2, the shovel head 1 is used as a hoe. At this time, the stress is concentrated on the hinge position of the mounting frame 10 and the connecting head 31, which will not affect the structure of the positioning sleeve 5, and will not affect the angle adjustment of the shovel head 1.

[0022] Furthermore, the upper end of the positioning sleeve 5 is sleeved on the outer circumference of the handle 2, and the inner circumference of the lower end of the positioning sleeve 5 is provided with an annular connecting boss 50, which is threadedly connected to the threaded column 30. The outer circumference of the lower portion of the positioning sleeve 5 is provided with an annular gripping boss 51, and the outer circumference of the gripping boss 51 is provided with strip holes 52 along the axial direction of the positioning sleeve 5. There are several strip holes 52, and all of the strip holes 52 are spaced apart along the circumference of the positioning sleeve 5. The provision of the gripping boss 51 is equivalent to enlarging the outer diameter of the positioning sleeve 5, making it easier for the human hand to hold it, and thus facilitating the application of force to the positioning sleeve 5. The provision of the strip holes 52 creates an uneven structure on the outer circumference of the gripping boss 51, increasing the friction with the palm of the hand and further improving the convenience of the rotation operation of the positioning sleeve 5.

[0023] like Figure 2 and Figure 4 As shown, a compression pad 8 is provided between the connector 31 and the positioning sleeve 5 and is sleeved on the threaded column 30. The compression pad 8 is made of rubber and can abut against the horizontal limit surface 6 or the vertical limit surface 7. An annular positioning groove 53 is provided on the outer peripheral surface of the lower end of the positioning sleeve 5. The outer edge of the compression pad 8 has an annular mounting ring 80. The inner wall of the mounting ring 80 is provided with an annular clamping protrusion 81, which is embedded in the positioning groove 53. The compression pad 8 made of rubber has a certain elasticity. The positioning sleeve 5 presses the mounting frame 10 into position through the compression pad 8. When the positioning sleeve 5 is pressed against the compression pad 8, the compression pad 8 produces a certain elastic deformation. The force of the elastic deformation acts on the positioning sleeve 5 and the mounting frame 10 respectively, making it difficult for the threaded connection between the positioning sleeve 5 and the threaded column 30 to loosen, thereby ensuring that the mounting frame 10 has a good positioning effect.

[0024] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
