Description

Technical Field

[0001] This invention relates to the field of measuring instrument technology, and in particular to a simple, extendable flower pole for measuring the surface height of glaciers. Background Technology

[0002] In engineering surveying, slant poles are generally used for marking or measurement. When measuring the height of a glacier surface, slant poles are required.

[0003] Patent application number CN202120048382.0, entitled "A Simple Telescopic Glacier Surface Height Measuring Pole," includes a base. A U-shaped plate is fixed to the top of the base. Springs are fixed to the inner walls of both sides of the U-shaped plate. A connecting block is fixed to one end of each spring. Each connecting block is slidably connected to the top of the base. A connecting rod is rotatably connected to the top of each connecting block via a pin. A pressure rod is rotatably connected to the top of each connecting rod via a pin. The top of each pressure rod slides through the top of the U-shaped plate. A pressure plate is positioned above the U-shaped plate. The top of each pressure rod is fixedly connected to the bottom of the pressure plate. A measuring cylinder is positioned on the top of the base, and the top of the measuring cylinder slides... Through the top of the U-shaped plate and the top of the pressure plate, the bottom two side walls of the measuring cylinder are provided with slots, and one side wall of the connecting block is fixed with a locking rod. Compared with the prior art, the present invention provides a simple and retractable glacier surface height measuring rod with the following advantages: This simple and retractable glacier surface height measuring rod, by setting a U-shaped plate, spring, connecting block, connecting rod, pressure rod, pressure plate and locking rod, can easily fix the measuring cylinder on the base when measurement is needed, so the staff does not need to hold it by hand. When it needs to be carried, the measuring cylinder can be removed from the base, and the extension or retraction of the measuring rod can be realized by setting a screw and a knob, so it is convenient for transportation.

[0004] In practical applications, the base needs to be placed on the glacier surface, which is relatively smooth and requires certain fixation or manual support before measurement and adjustment can be performed. Existing methods generally involve inserting a drill rod into a hole in the base plate for fixation, which involves many steps, followed by limiting and fixing the rod. In extreme environments, this increases the number of steps for the user, which is not conducive to measurement and consumes a lot of the operator's physical strength. Therefore, there is a need for a simple, retractable glacier surface height measuring rod that is easy for the operator to operate simultaneously. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The main objective of this invention is to provide a simple, extendable glacier surface height measuring pole to solve the problem of insufficient grip on the base plate.

Powerful springs are provided at the four corners of the lower end of the fixed plate, and the powerful springs drive the fixed seat to move upwards.

[0011] In a further preferred embodiment of the present invention, the improved support frame further includes a through hole, a limiting seat, a limiting hole, a fixing cylinder, a square hole, and a plug rod. A through hole adapted to the first flower rod is provided at the middle of the upper end of the anti-slip frame body. A limiting seat is provided at the middle of the inner bottom of the anti-slip frame body, and a limiting hole aligned with the opening on the side wall of the limiting seat is provided on the side wall of the first flower rod. A fixing cylinder is provided at both sides of the inner bottom of the anti-slip frame body, and a square hole is provided on the end face of the fixing cylinder. A movable limiting device is provided between the square hole and the limiting hole, and a plug rod for fixing the limiting device is provided on the fixing cylinder and the anti-slip frame body.

[0012] In a further preferred embodiment of the present invention, the limiting device includes a limiting block, a first irregular block, a square block, a square strip, an insertion hole, and a return spring. A limiting block for fixing a first flower rod is inserted into the limiting hole. The other end of the limiting block is provided with a first irregular block, and the other end of the first irregular block is equipped with a square block. The end face of the square block is provided with a square strip, and the square strip passes through the square hole and is inserted into the fixing cylinder. The upper end of the square strip is provided with an insertion hole adapted to the insertion rod, and the rod body of the square strip is fitted with a return spring.

[0013] In a further preferred embodiment of the present invention, the gripping device further includes a second irregularly shaped block, and the upper end of the fixing plate is provided with a second irregularly shaped block adapted to the first irregularly shaped block. The contact surface between the second irregularly shaped block and the first irregularly shaped block is designed as an inclined surface. The limiting device and the gripping device cooperate with the improved support frame. The limiting device is used to fix the first flower pole and the improved support frame, and the gripping device is used to securely place the improved support frame on the glacier ground. The improved support frame controls the opening and closing of the limiting device and the gripping device. The user only needs to rotate the plug rod to achieve this, which is convenient for the user to operate in extreme weather conditions.

[0014] In a further preferred embodiment of the present invention, the insertion rod is located in the openings on both sides of the end face of the anti-slip frame, and the insertion rod is connected to the anti-slip frame by a thread;

[0015] In a further preferred embodiment of the present invention, the fixing cylinder and the anti-slip frame are integrally formed, and the opening of the fixing cylinder faces outward, the square hole is adapted to the square strip, and the square strip moves within the square hole;

[0016] In a further preferred embodiment of the present invention, the limiting block and the first irregular block are integrally formed, and the contact end between the limiting block and the limiting seat is smoothly formed. The contact surfaces of the first irregular block and the second irregular block have burrs. The second irregular block, the fixing plate, and the fixing seat are integrally formed, and the fixing seat is threadedly connected to the gripping drill bit. With the cooperation of the limiting block, the return spring, the square bar, and the fixing cylinder, the limiting block can be extended and retracted within the limiting hole, thereby realizing the fixing and disassembly between the first flower rod and the limiting seat. When used individually, it can also be opened and closed by rotating the insertion rod, which is also convenient for users to operate in extreme environments.

[0017] In a further preferred embodiment of the present invention, the limiting frame and the blocking frame are welded and fixed, and the limiting frame and the stop bar cooperate with the limiting block to prevent the fixed seat from moving excessively upward, and the blocking frame prevents the fixed seat from moving excessively downward; the gripping drill bit changes position through the cooperation of the strong spring, the fixed seat, the limiting block, the limiting frame and the second irregular block and the first irregular block. When it retracts into the anti-slip frame body, it can avoid contact between the gripping drill bit and the human body and cause damage. When it protrudes from the anti-slip frame body, it can be embedded in the glacial ground, improving the stability of the anti-slip frame body.

[0018] In a further preferred embodiment of the present invention, the separation of the insert rod from the square strip causes the square strip to continuously move outward toward the outside of the anti-slip frame, thereby causing the limiting block and the first irregular block to move outward to separate the first irregular block and the second irregular block, and the second irregular block moves upward to retract the gripping drill bit.

[0019] (III) Beneficial Effects

[0020] The above-described technical solution of the present invention has the following advantages:

[0021] The present invention provides a simple, extendable glacier surface height measuring pole.

[0022] 1. The limiting device and the gripping device work together with the improved support frame. The limiting device is used to fix the first flower pole and the improved support frame, and the gripping device is used to place the improved support frame firmly on the glacier ground. The improved support frame controls the opening and closing of the limiting device and the gripping device. The user only needs to turn the plug rod to achieve this, which makes it convenient for the user to operate in extreme weather conditions.

[0023] 2. With the cooperation of the limiting block, the return spring, the square bar, and the fixing cylinder, the limiting block can extend and retract within the limiting hole, thereby achieving the fixing and disassembly between the first flower rod and the limiting seat. When used individually, it can also be opened and closed by rotating the insert rod, which is also convenient for users to operate in extreme environments.

[0024] 3. The gripping drill bit changes position through the cooperation of a strong spring, a fixed seat, a limiting block, a limiting frame, and the second and first irregular blocks. When it retracts into the anti-slip frame, it can prevent the gripping drill bit from contacting the human body and causing injury. When it protrudes from the anti-slip frame, it can embed itself into the glacial ground, improving the stability of the anti-slip frame. Attached Figure Description

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1:

[0036] like Figure 1 , 2 As shown in 3, 4, 5, 6, 7, and 8, a simple and retractable glacier surface height measuring rod includes a first rod 4, a second rod 5, and a bubble leveling plate 6. The upper end hole of the first rod 4 is provided with a second rod 5 that is adapted to it. The top of the second rod 5 is provided with a bubble leveling plate 6. The second rod 5 extends out to adjust the height of the entire rod.

[0037] The lower end of the first flower pole 4 is provided with an improved support frame 1. The improved support frame 1 is provided with a limiting device 2 and a ground gripping device 3. The limiting device 2 is used to fix the first flower pole 4 and the improved support frame 1. The ground gripping device 3 is used to securely place the improved support frame 1 on the glacier ground. The improved support frame 1 controls the opening and closing of the limiting device 2 and the ground gripping device 3 at the same time.

[0038] The improved support frame 1 includes an anti-slip frame body 101, a limiting groove 108, a blocking frame 109, a limiting frame 110, and a sliding groove 111. Limiting grooves 108 are provided on both sides of the lower end of the anti-slip frame body 101. A blocking frame 109 is provided at the lower end of the limiting groove 108. Two sets of limiting frames 110 are provided at the upper end of the blocking frame 109. A sliding groove 111 is provided in the middle of each set of limiting frames 110. A ground-gripping device 3 is provided within the limiting groove 108. The ground-gripping device 3 includes a fixing plate 302, a fixing seat 303, a limiting block 304, a stop bar 305, and a strong spring. 306 and gripping drill bit 307, a fixed seat 303 is provided in the groove of the limiting groove 108, and a limiting block 304 is provided on both sides of the fixed seat 303. The limiting block 304 moves up and down in the sliding groove 111. A stop bar 305 is installed on the upper end of each set of limiting frame 110 to block the limiting block 304. A gripping drill bit 307 is provided at the lower end of the fixed seat 303. The gripping drill bit 307 is inserted into the glacier ground to stabilize the anti-slip frame 101. A strong spring 306 is provided at the four corners of the lower end of the fixed plate 302. The strong spring 306 drives the fixed seat 303 to move upward.

[0039] The improved support frame 1 also includes a through hole 102, a limiting seat 103, a limiting hole 104, a fixing cylinder 105, a square hole 106, and a plug rod 107. The upper middle part of the anti-slip frame body 101 is provided with a through hole 102 that is adapted to the first flower rod 4. The middle part of the inner bottom of the anti-slip frame body 101 is provided with a limiting seat 103. The side wall of the limiting seat 103 is provided with a limiting hole 104 that is aligned with the opening on the side wall of the first flower rod 4. The two sides of the inner bottom of the anti-slip frame body 101 are provided with a fixing cylinder 105. The end face of the fixing cylinder 105 is provided with a square hole 106. A movable limiting device 2 is provided between the square hole 106 and the limiting hole 104. The fixing cylinder 105 and the anti-slip frame body 101 are provided with a plug rod 107 for fixing the limiting device 2.

[0040] The limiting device 2 includes a limiting block 201, a first irregular block 202, a square block 203, a square strip 204, an insertion hole 205, and a return spring 206. The limiting block 201, which fixes the first flower rod 4, is inserted into the limiting hole 104. The other end of the limiting block 201 is provided with the first irregular block 202. The other end of the first irregular block 202 is provided with the square block 203. The end face of the square block 203 is provided with the square strip 204. The square strip 204 passes through the square hole 106 and is inserted into the fixing cylinder 105. The upper end of the square strip 204 is provided with an insertion hole 205 that is compatible with the insertion rod 107. The rod body of the square strip 204 is fitted with the return spring 206. The gripping device 3 also includes a second irregular block 301. The upper end of the fixing plate 302 is provided with a second irregular block 301 that is compatible with the first irregular block 202. The contact surface between the second irregular block 301 and the first irregular block 202 is designed with an inclined surface.

[0041] The insertion rod 107 separates from the square bar 204, causing the square bar 204 to continuously move outwards from the anti-slip frame 101. This, in turn, causes the limiting block 201 and the first irregular block 202 to move outwards, separating the first irregular block 202 and the second irregular block 301. The second irregular block 301 then moves upwards to retract the gripping drill bit 307. In use, the improved support frame 1, the limiting device 2, and the gripping device 3 are first installed. The gripping drill bit 307 is aligned with the lower end of the fixed base 303 and drilled. The gripping drill bit 307 is fixedly connected to the fixed base 303 via threads. The strong spring 306 is placed under the fixed plate 302. At the four corners, a strong spring 306 is fixedly connected to the fixing plate 302 and the blocking frame 109. The limiting block 304 is embedded in the slide groove 111 opened in the limiting frame 110. When the fixing seat 303 is pulled up, the stop bar 305 is installed on the upper end of the limiting frame 110 by bolts to allow the limiting block 304 to fall out of the slide groove 111, thus completing the fixation between the entire gripping device 3 and the anti-slip frame 101. Then, the limiting device 2 is assembled. The limiting block 201 is inserted into the limiting hole 104. The square block 203 and the square bar 204 are designed as a single unit. The square block 203 contacts the other side of the first irregular block 202. At one end, the two are fixed with bolts. The return spring 206 is sleeved on the rod body of the square bar 204. The square bar 204 is inserted into the square hole 106 opened in the fixed cylinder 105. The end of the return spring 206 is fixedly connected to the fixed cylinder 105. During the reset process, the return spring 206 drives the square block 203 to move towards the fixed cylinder 105, thereby realizing the separation between the first irregular block 202 and the limiting block 201 and the gripping device 3 and the limiting seat 103. When the first irregular block 202 separates from the second irregular block 301, the second irregular block 301 is no longer subjected to the pressure from the upper end. During the process of the force spring 306 returning to its original state, it lifts the second irregular block 301, thereby driving the fixed seat 303 and the gripping drill bit 307 to move upward, and vice versa. Due to the cooperation between the limiting device 2 and the gripping device 3 and the improved support frame 1, the limiting device 2 is used to fix the first flower rod 4 and the improved support frame 1, and the gripping device 3 is used to securely place the improved support frame 1 on the glacier ground. The improved support frame 1 controls the opening and closing of the limiting device 2 and the gripping device 3. The user only needs to rotate the plug rod 107 to achieve this, which is convenient for the user to operate in extreme weather conditions.

[0042] Example 2:

[0043] like Figure 1 , 4As shown in Figures 5, 6, 7, and 8, components that are the same as or corresponding to those in Embodiment 1 are marked with the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference lies in that the insertion rod 107 is located within the openings on both sides of the end face of the anti-slip frame 101, and the insertion rod 107 is threadedly connected to the anti-slip frame 101; the fixing cylinder 105 and the anti-slip frame 101 are integrally formed, the opening of the fixing cylinder 105 faces outwards, the square hole 106 is adapted to the square strip 204, and the square strip 204 moves within the square hole 106; the limiting block 201 and the first irregularly shaped block 202 are integrally formed, the contact end of the limiting block 201 with the limiting seat 103 is smoothly formed, and the first irregularly shaped block 202 and the second irregularly shaped block 202... The contact surface of block 301 has burrs. The second irregular block 301, fixing plate 302 and fixing seat 303 are integrally set. The fixing seat 303 is threadedly connected to the gripping drill bit 307. With the cooperation of the limiting block 201, the return spring 206, the square bar 204 and the fixing cylinder 105, the limiting block 201 can be extended and retracted in the limiting hole 104, thereby realizing the fixing and disassembly between the first flower rod 4 and the limiting seat 103. When used alone, it can also be opened and closed by rotating the plug rod 107, which is also convenient for users to operate in extreme environments.

[0044] The limiting frame 110 and the blocking frame 109 are welded and fixed. The limiting frame 110 and the stop bar 305 cooperate with the limiting block 304 to prevent the fixed seat 303 from moving too high. The blocking frame 109 prevents the fixed seat 303 from moving too low. The gripping drill bit 307 changes position through the cooperation of the strong spring 306, the fixed seat 303, the limiting block 304, the limiting frame 110, the second irregular block 301, and the first irregular block 202. When it retracts into the anti-slip frame 101, it can avoid contact with the human body and cause damage. When it protrudes from the anti-slip frame 101, it can be embedded in the glacial ground, improving the stability of the anti-slip frame 101.
