Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, and in particular to a non-destructive testing needle for concrete strength. Background Technology

[0002] When constructing a house, a large amount of concrete is usually required to pour the house frame. The use of concrete needs to be tested to prevent the construction of poor quality buildings that may pose safety hazards. Therefore, after the concrete is poured, it is necessary to test whether its strength is up to standard. Generally, a non-destructive testing needle for concrete strength is used to test the concrete.

[0003] Existing technologies, such as patent CN211784863U, disclose a needle-type concrete strength detector. This patent employs a cavity with a hollow chamber and a shaft hole inside. The side wall of the cavity also has a notch. The shaft hole communicates with the hollow chamber, and a stepped shaft passes through the shaft hole. A punch is connected to the tail end of the shaft. A fixed magnet is installed at the top of the cavity, and a movable magnet with the same polarity as the fixed magnet is installed at the head end of the shaft. A fulcrum is set at the bottom wall of the notch, and a lever is hinged to the fulcrum. This novel device solves the problem that in traditional testing instruments, the elasticity of the spring will decrease after prolonged use, reducing the penetration depth of the punch and affecting the detection accuracy.

[0004] In daily work, when using the equipment, the user holds the equipment to test the concrete. Because the equipment uses an impact method to test the concrete, the impact can easily generate strong vibrations, causing soreness in the user's hands and making it difficult to hold the equipment, resulting in it falling to the ground and being damaged. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where vibrations generated during equipment use can cause damage to the user's hands, and to propose a non-destructive testing needle for concrete strength.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a non-destructive testing needle for concrete strength, comprising a main body, a display, a probe, and a connector. The display is fixedly connected to the surface of the main body, the probe is fixedly connected to one end of the main body through the connector, a protective device is fixedly installed on the surface of the main body, a first enclosure plate is fixedly connected to the side of the main body, the gap between the main body and the first enclosure plate forms a groove, a second enclosure plate is slidably connected in the groove of the first enclosure plate, a sliding groove is provided on the side wall of the groove, a slider is fixedly connected to the side wall of the second enclosure plate, the second enclosure plate is slidably connected to the inside of the groove of the first enclosure plate through the slider and the sliding groove, a sliding sleeve is fixedly connected to the position of the main body inside the groove, and a sliding rod is provided inside the first enclosure plate corresponding to the sliding sleeve.

[0007] Furthermore, the slide rod is slidably connected to the slide sleeve, and a first spring is sleeved on the outer wall of the slide rod and the slide sleeve. Through the cooperation of the slide sleeve and the slide rod, the first spring can be limited, reducing the situation where the first spring will deviate violently when pushing the second enclosure plate during equipment use, resulting in the inability to apply force effectively.

[0008] Furthermore, one end of the first spring is fixedly connected to the main body, and the other end is fixedly connected to the inside of the second enclosure.

[0009] Furthermore, a contact plate is fixedly connected to the side of the second panel away from the first panel. The contact plate is made of non-slip material, and the pits and depressions on its surface help the user to grip it more comfortably.

[0010] Furthermore, an auxiliary component is fixedly installed on the side of the main body away from the display. The auxiliary component includes a mounting base and a connecting ring. The mounting base is fixedly connected to the side of the main body away from the display. The connecting ring is sleeved on the surface of the probe. A contact ring is fixedly connected to the inner wall of the connecting ring. The contact ring is slidably connected to the surface of the probe. A connecting plate is fixedly connected to the surface of the connecting ring. A connecting rod is fixedly connected to the end of the connecting plate near the main body. The connecting rod is slidably connected inside the mounting base. By setting the contact ring, the surface of the probe can be cleaned, reducing the possibility that foreign objects may easily adhere to the contact end between the probe and the material during use, affecting the detection accuracy of the equipment.

[0011] Furthermore, a limit block is fixedly connected to the end of the connecting rod away from the connecting plate. The limit block is slidably connected inside the mounting base. The limit block is provided to facilitate the limiting of the connecting rod.

[0012] Furthermore, a second spring is fixedly connected to the end of the limiting block away from the connecting rod, and the end of the second spring away from the limiting block is fixedly connected to the interior of the mounting base. The second spring is provided to facilitate the application of tension to the connecting rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a protective device, when the equipment is in use, the user holds the contact plate and moves the second enclosure plate inside the first enclosure plate. When the second enclosure plate moves, it drives the slider to move inside the slide groove. When the second enclosure plate moves, it drives the sliding sleeve to move on the surface of the sliding rod, which then abuts the first spring and deforms to generate elastic force. By setting a protective device, the vibration force generated when the equipment is in use is effectively reduced, which reduces the vibration generated on the hand when the equipment is in use. When using general equipment, the user holds the equipment to test the concrete. Since the equipment uses an impact method to test the concrete, the impact can easily generate strong vibration, causing soreness in the user's hand and making it difficult to hold the equipment and causing it to fall to the ground and be damaged. This protective device, through the cooperation between the first enclosure plate, the second enclosure plate, the sliding sleeve and the sliding rod, reduces the vibration generated when the equipment is in use and greatly improves the stability of the user holding the equipment.

[0015] 2. In this utility model, by setting an auxiliary component, when the device is in use, the user pulls the connecting plate to move the connecting ring and the connecting rod inside the mounting base. When the connecting ring moves, it drives the internal contact ring to clean the surface of the probe. When the connecting rod moves, it drives the limiting block to stretch the second spring and generate elastic force. By setting the auxiliary component, the surface of the probe is effectively cleaned, which plays a role in quickly cleaning the surface of the probe. After the device has been used for a long time, the contact surface between the probe and the material is prone to adsorb foreign objects, which affects the detection accuracy of the device. This auxiliary component, through the cooperation between the connecting ring, contact ring, connecting plate, connecting rod and mounting base, can clean the surface of the probe, improving the practicality of the device.

[0026] Specifically, the slide rod 57 is slidably connected to the slide sleeve 58, and a first spring 59 is sleeved on the outer wall of the slide rod 57 and the slide sleeve 58.

[0027] In this embodiment, the cooperation of the sliding sleeve 58 and the sliding rod 57 can limit the first spring 59, reducing the situation where the first spring 59 will deviate violently when pushing the second enclosure 52 during equipment use, resulting in the inability to apply force effectively.

[0028] Specifically, one end of the first spring 59 is fixedly connected to the main body 1, and the other end is fixedly connected to the inside of the second enclosure 52.

[0029] Specifically, a contact plate 53 is fixedly connected to the side of the second enclosure 52 away from the first enclosure 51. The contact plate 53 is made of anti-slip material, and the pits and depressions on its surface help the user to hold it more comfortably.

[0030] In this embodiment: An auxiliary component 6 is fixedly installed on the side of the main body 1 away from the display 2. The auxiliary component 6 includes a mounting base 61 and a connecting ring 66. The mounting base 61 is fixedly connected to the side of the main body 1 away from the display 2.

By setting the auxiliary component 6, the surface of the probe rod 3 is effectively cleaned, which plays a role in quickly cleaning the surface of the probe rod 3. After the equipment has been used for a long time, the contact surface between the probe rod 3 and the material is prone to adsorb foreign objects, which affects the detection accuracy of the equipment. This auxiliary component 6, through the cooperation between the connecting ring 66, contact ring 67, connecting plate 63, connecting rod 62 and mounting base 61, can clean the surface of the probe rod 3 and improve the practicality of the equipment.
