A measuring pin 104 is slidably arranged on the vertical plate 101 along a first direction, the first direction extends along a horizontal direction and is perpendicular to the first surface, the measuring pin 104 can penetrate the measured surface of the object, and the measuring pin 104 is located below the mounting block 102; the pendulum has an initial position and a striking position, the pendulum has potential energy to approach the striking position when it is at the initial position, and the pendulum can collide with the measuring pin 104 at the striking position; the reset mechanism includes a push rod 127, an adjustment assembly and a transmission assembly, the push rod 127 is slidably arranged on the vertical plate 101 along the first direction, and the push rod 127 penetrates the vertical plate 101 and can abut against the measured surface of the object, when the vertical plate 101 approaches the measured surface of the object, the push rod 127 first contacts the measured surface of the object. The adjustment component is used to adjust the pressure between the push rod 127 and the measured surface of the object when the vertical plate 101 contacts the measured surface of the object, and the pressure between the vertical plate 101 and the measured surface of the object is less than the pressure between the push rod 127 and the measured surface of the object; when the vertical plate 101 approaches the measured surface of the object, the transmission component can move the pendulum from the striking position to the initial position through the relative movement between the push rod 127 and the vertical plate 101.

[0023] A push rod 127 is provided, and a rough positioning can be performed before the vertical plate 101 contacts the measured surface of the object. Through the cooperation between the transmission component, the pendulum and the push rod 127, the pendulum can be reset when the vertical plate 101 approaches the measured surface of the object. When multiple points are detected, the continuity of the detection process can be improved, the operation steps can be reduced, and the ease of use is improved; an adjustment component is provided, and when detecting an object with a larger surface roughness, the friction between the vertical plate 101 and the measured surface of the object can make the vertical plate 101 relatively stable, and the contact pressure between the push rod 127 and the measured surface of the object can be appropriately reduced, thereby reducing the burden on the operator; when detecting an object with a smaller surface roughness, the vertical plate 101 is easier to slide relative to the measured surface of the object, and the contact pressure between the push rod 127 and the measured surface of the object can be appropriately increased, thereby improving the stability of the vertical plate 101 on the measured surface of the object.

[0024] In this embodiment, the adjustment component includes a limit block 105, a limit ring 106 and a first spring 107. The limit block 105 is slidably arranged on the mounting block 102 along the first direction, and the limit block 105 is sleeved on the push rod 127. The limit block 105 is slidably connected to the push rod 127. A U-shaped plate 108 is provided on the mounting block 102. The two ends of the U-shaped plate 108 are respectively fixedly connected to the mounting block 102. A hole is formed between the U-shaped plate 108 and the mounting block 102. The limit block 105 slides in the hole along the first direction. A first bolt 109 is threadedly connected to the U-shaped plate 108. The first bolt 109 can abut against the limit block 105. When the first bolt 109 abuts against the limit block 105, the limit block 105 cannot move relative to the vertical plate 101. The limit ring 106 is sleeved on the push rod 127, and the limit ring 106 is fixedly connected to the push rod 127. The limit ring 106 and the limit block 105 are both located on the same side of the vertical plate 101 as the mounting block 102. The first spring 107 is sleeved on the push rod 127, and the two ends of the first spring 107 are respectively connected to the limit block 105 and the limit ring 106. The first spring 107 is always in a compressed state. The limit ring 106 abuts against the vertical plate 101 when the push rod 127 is not contacted by any object, and the position of the limit block 105 on the mounting block 102 is moved. Then, the limit block 105 is limited by the first bolt 109, which can change the elastic potential energy of the first spring 107, thereby changing the pressure between the push rod 127 and the measured surface of the object when the vertical plate 101 contacts the measured surface of the object.

[0025] In this embodiment, the transmission assembly includes a gear 110 and a rack plate 111. The gear 110 is an incomplete gear 110. The gear 110 is sleeved on the rotating shaft 103, and the gear 110 can rotate synchronously with the rotating shaft 103. The rack plate 111 is fixedly mounted on the push rod 127 and the rack plate 111 is located below the gear 110. The rack plate 111 can mesh with the gear 110. The gear 110 and the rack plate 111 are both located on the side of the push rod 127 away from the limit block 105 in the first direction. If the pendulum is in the striking position and when the vertical plate 101 is approaching the measured surface of the object, the push rod 127 abutting the measured surface of the object will slide in the first direction relative to the vertical plate 101. At this time, the rack plate 111 can mesh with the gear 110 after moving along the first direction with the push rod 127. The rack plate 111 can drive the rotating shaft 103 to rotate through the gear 110, and the rotating shaft 103 drives the pendulum to move toward the initial position of the pendulum; if the pendulum is in the striking position and when the vertical plate 101 is moving away from the measured surface of the object, the push rod 127 abutting the measured surface of the object will drive the rack plate 111 to move in the first direction relative to the vertical plate 101 under the action of the first spring 107. At this time, the rack plate 111 will mesh with a few teeth of the gear 110, and drive the pendulum to continue to move in the direction away from its initial position through the rotating shaft 103, and then the rack plate 111 will disengage from the gear 110 until the limit ring 106 abuts against the vertical plate 101.

[0026] In this embodiment, a rubber pad 112 is provided at one end of the push rod 127 that contacts the measured surface of the object. The rubber pad 112 can increase the friction between the push rod 127 and the measured surface of the object, thereby improving the stability of the vertical plate 101 on the measured surface of the object.

[0027] In this embodiment, a groove 113 is opened on the first surface, and the push rod 127 is slidably set in the groove 113. The rubber pad 112 can be completely accommodated in the groove 113. When the vertical plate 101 contacts the surface of the object to be measured, the rubber pad 112 is flush with the plane where the vertical plate 101 is located. If the plane where the rubber pad 112 is located is higher than other positions on the surface of the object to be measured, the rubber pad 112 can also be accommodated in the groove 113, so that the vertical plate 101 can fully contact the surface of the object to be measured, thereby enhancing its applicability.

[0028] In this embodiment, a receiving groove 114 is provided on the mounting block 102, and a second spring 115 is provided in the receiving groove 114 to extend and retract along the first direction. A first clamping plate 116 is provided on the vertical plate 101 to slide along the first direction, and one end of the first clamping plate 116 extends into the receiving groove 114 and is connected to one end of the second spring 115. The pendulum includes a connecting rod 117 and a hammer body 118, one end of the connecting rod 117 is sleeved on the rotating shaft 103, and the connecting rod 117 is fixedly connected to the rotating shaft 103, and a connecting rod 117 is provided on the connecting rod 117. There is a slot 119, and the first clamping plate 116 can be clamped with the connecting rod 117 through the slot 119. When the first clamping plate 116 is clamped with the connecting rod 117, an angle is set between the connecting rod 117 and the vertical plate 101 to avoid the situation where the center of gravity of the connecting rod 117 and the hammer body 118 and the axis of the rotating shaft 103 are located on the same vertical plane and the connecting rod 117 does not rotate around the rotating shaft 103 after the first clamping plate 116 and the connecting rod 117 are separated. When the first clamping plate 116 is clamped with the connecting rod 117, the pendulum is in the initial position. Two handles 120 are fixedly mounted on one surface of the vertical plate 101 with the mounting block 102. The two handles 120 are respectively located at two ends of the axial direction of the rotating shaft 103. A dial plate 121 is provided on the connecting rod 117. The dial plate 121 extends along the axial direction of the rotating shaft 103 and penetrates the mounting block 102. The dial plate 121 is slidably connected to the mounting block 102 along a first direction. The end of the dial rod away from the first clamping plate 116 is close to the handle 120. The operator holds the two handles 120 with both hands, and then can push the dial plate 121 with fingers to disengage the first clamping plate 116 from the connecting rod 117. The hammer 118 drives the connecting rod 117 to rotate around the rotating shaft 103 under the action of its own gravity and rotates to the striking position to hit the measuring nail 104.

[0029] In this embodiment, a third spring 122 and a second clamping plate 123 are provided on the mounting block 102. The third spring 122 is arranged in the receiving groove 114 and is located above the first clamping plate 116. The third spring 122 is extended and retracted along the first direction. The second clamping plate 123 is slidably arranged on the mounting block 102 along the first direction, and one end of the second clamping plate 123 extends into the receiving groove 114 and is connected to the third spring 122. When the pendulum is in the initial position, the connecting rod 117 contacts the second clamping plate 123. In order to ensure that the pendulum can move smoothly to the initial position, the first surface and the measured surface of the object are close to each other and before contact, the rack plate 1 11 will drive the gear 110 to rotate and drive the connecting rod 117 to cross the vertical plane where the axis of the rotating shaft 103 is located through the rotating shaft 103. At this time, the first clamping plate 116 slides in the clamping groove 119, and the second clamping plate 123 abuts against the connecting rod 117. The rack plate 111 and the gear 110 are in a toothing state under the action of the third spring 122 and last for a short period of time. Then the rack plate 111 will gradually move away from the gear 110 and no longer contact the gear 110. The second clamping plate 123 will push the connecting rod 117 to cross the vertical plane where the axis of the rotating shaft 103 is located again, so that the first clamping plate 116 and the connecting rod 117 are clamped.

[0030] In this embodiment, a level bubble 124 is provided on the upper surface of the mounting block 102. If the surface of the object to be measured is uneven and the vertical plate 101 cannot be placed vertically, the vertical plate 101 can be made vertical by observing the level bubble 124, thereby improving the accuracy of the detection.

[0031] In this embodiment, three second bolts 125 are provided on the vertical plate 101, and the three second bolts 125 respectively penetrate the vertical plate 101 along the first direction and are threadedly connected to the vertical plate 101, wherein two second bolts 125 are located in the same horizontal plane and are located above another second bolt 125, and the two second bolts 125 located above are located on both sides of the second bolt 125 located below them in the axial direction of the rotating shaft 103, and the second bolt 125 located below the two second bolts 125 is located directly below or directly above the measuring pin 104. When the measured surface of the object is uneven and the vertical plate 101 is adjusted to be vertical by the level bubble 124, the second bolt 125 can be rotated to make the second bolt 125 contact with the measured surface of the object, thereby providing a fulcrum for the operator for easy use.

[0032] In this embodiment, a protective frame 126 is provided on the mounting block 102. The protective frame 126 is U-shaped. Both ends of the protective frame 126 are respectively connected to the mounting block 102, and the two ends of the protective frame 126 are located on both sides of the pendulum in the axial direction of the rotating shaft 103. The pendulum can pass through the protective frames 126 when switching between the initial position and the striking position. The swing range of the pendulum can be intuitively seen from the protective frame 126, thereby preventing the pendulum from being affected by external factors when swinging.

[0033] The working principle of the inorganic gelling material strength detection device provided in the above embodiment is: First, the position where the measuring pin 104 is inserted is marked on the measured surface of the object, and then the operator moves the vertical plate 101 by holding the handle 120 and moves the measuring pin 104 on the vertical plate 101 to the position, and then pushes the vertical plate 101 in the first direction so that the push rod 127 contacts the measured surface of the object. Continue to push the vertical plate 101, the push rod 127 is stationary relative to the measured surface of the object, and the push rod 127 slides relative to the vertical plate 101, and the first spring 107 is compressed (the distance between the limit block 105 and the vertical plate 101 can be adjusted according to the friction between the measured surface of the object and the vertical plate 101, so as to change the initial elastic force of the first spring 107, change the pressure between the push rod 127 and the measured surface of the object when the vertical plate 101 contacts the measured surface of the object, and improve the operator's comfort). Then the gear 110 gradually approaches the rack plate 111 and finally meshes with the rack plate 111. While the gear 110 rolls on the rack plate 111, it drives the connecting rod 117 to rotate through the rotating shaft 103. The connecting rod 117 drives the hammer body 118 to rotate upward around the rotating shaft 103. The connecting rod 117 and the hammer body 118 pass through the protective frame 126 and continue to rotate. When the connecting rod 117 rotates to the vertical state, the first clamping plate 116 has been inserted into the clamping groove 119 under the action of the second spring 115, and the connecting rod 117 and the second clamping plate 123 are in abutment state under the action of the third spring 122, and the rack plate 111 and the gear 110 can be disengaged. After the rack plate 111 and the gear 110 are disengaged, the connecting rod 117 is pushed downward by the second clamping plate 123 to rotate, and the rack plate 111 and the gear 110 are meshed again. As the vertical plate 101 approaches the measured surface of the object, the rack plate 111 and the gear 110 are in a toothing state. Until the rack plate 111 is away from the gear 110, the connecting rod 117 drives the hammer body 118 to rotate downward to the initial position under the push of the second clamping plate 123. At this time, the first clamping plate 116 is clamped with the connecting rod 117 through the clamping groove 119, and the connecting rod 117 maintains the initial position.

[0034] Continue to push the vertical plate 101 until it contacts the measured surface of the object, then observe the level bubble 124. If the vertical plate 101 is not in a vertical state, adjust the second bolt 125 to make the vertical plate 101 vertical, then push the dial plate 121, the dial plate 121 drives the first clamping plate 116 to compress the second spring 115, the first clamping plate 116 slides out of the clamping slot 119, the hammer 118 drives the connecting rod 117 to swing downward and hit the measuring nail 104, and the measuring nail 104 pierces the measured surface of the object.

[0035] By repeating the above operation, multiple points on the surface of the object to be measured can be punctured continuously, and then the data can be measured through the measuring device.

[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
