Description

Technical Field

[0001] The utility model relates to the technical field of sealant detection equipment, and more particularly to a high-temperature displacement detection device for thermoplastic spacer sealant. Background Art

[0002] Glass sealant is a chemical product specifically designed for sealing and bonding joints on glass and various other substrates. Its primary functions are to provide waterproofing, windproofing, sound insulation, and structural connection and sealing. Tensile strength is also a mechanical property of a fully cured sealant. Tensile strength, also known as tensile strength or tear strength, commonly known as tensile strength, refers to a material's ability to resist damage when subjected to tension. Sealant strength requirements are specific to its intended use, especially for structural sealants, which have a minimum strength requirement specified in national standards. Sealant with insufficient strength will not meet the requirements of its intended use.

[0003] Chinese utility model patent application CN217466483U discloses a tensile strength tester for silicone sealants used in construction. The device comprises a fixing plate, a sealant fixing mechanism, a sealant stretching mechanism, and a tensile strength tester. While capable of testing sealant tensile strength, the device can only detect horizontal tensile forces, not inclined forces.

[0004] During the use of a building, not only will it generate pulling force in the horizontal direction, but it will also generate pulling force in the inclined direction due to the settlement of the building. However, the current sealant displacement detection device cannot detect the pulling force in the inclined direction, and the detection range is limited. Moreover, during the detection, the sealant may not be clamped firmly or may even fall off during the detection, which will affect the accuracy of the detection data.

[0005] Therefore, it is necessary to propose a high-temperature displacement detection device for thermoplastic spacer sealants to solve the above problems. Utility Model Content

The clamping assembly 108 holds a test block, and a sealant is applied between the two test blocks. The sealant is applied between the two square test blocks, and after it dries, a tensile test is performed on it.

[0035] refer to Figures 4 to 6The clamping assembly 108 includes a support frame 109, a fixed plate 110 and a fixed claw 111. The support frame 109 is fixedly connected to the top of the fixed plate 110. A rotating shaft is fixedly connected between the support frame 109 and the fixed plate 110. The fixed claw 111 can rotate 90 degrees with the rotating shaft as the axis. The fixed claw 111 is rotatably connected between the support frame 109 and the fixed plate 110. An arc-shaped sliding groove 112 is opened inside the fixed plate 110. The two ends of the sliding groove 112 are aligned with the two positioning holes 1 24, is used to limit the fixing claw 111 to two positions. The top of the fixing claw 111 is fixedly connected to a fixing rod 113 that passes through the sliding groove 112. A fastening handle 114 is fixed to the fixing rod 113. The fastening handle 114 is eccentrically arranged. Through the eccentric arrangement, it can be squeezed downward to reduce the distance between the fixing claw 111 and the fixing plate 110, thereby fixing the fixing claw 111 and the fixing plate 110 together. The top of the fixing rod 113 is hinged with the fastening handle 114;

[0036] refer to Figures 4 to 6 The bottom of the fixed jaw 111 is hinged with a lower clamping jaw 115. The test block is clamped and fixed by changing the distance between the fixed jaw 111 and the lower clamping jaw 115. A strip groove 116 is provided inside the lower clamping jaw 115. A clamping bolt 117 is movably connected inside the strip groove 116. The bottom of the clamping bolt 117 is fixedly connected to a curved rod 118 located at the bottom of the lower clamping jaw 115. The strip groove 116 and the clamping bolt 117 cooperate with each other. When the lower clamping jaw 115 rotates upward, the clamping bolt 117 slides in the strip groove 116. The top of the clamping bolt 117 extends from the fixed jaw 111, and a fastening nut 119 is threaded on it.

[0037] refer to Figure 6 and Figure 7 A mounting hole 120 is provided at the bottom of the fixing claw 111, and a positioning ball 122 and a spring 123 are installed inside the mounting hole 120. The spring 123 pushes the positioning ball 122 out of the mounting hole 120 so that it is located in the positioning hole 124, thereby positioning the position of the fixing claw 111. A hollow ball rack 121 is threadedly connected to the inner wall of the mounting hole 120, and a positioning ball 122 and a spring 123 are installed inside the ball rack 121. The spring 123 pushes the positioning ball 122 out of the mounting hole 120, and symmetrical positioning holes 124 are provided inside the support frame 109. The two positioning holes 124 correspond to the two ends of the sliding groove 112, and are used to limit the horizontal and vertical states of the fixing claw 111.

[0038] Specifically, refer to Figure 1 and Figure 2The vertical frame 102 includes a guide block 125 and a support platform 126. A threaded rod 104 rotates between the two support platforms 126. The vertical moving block 105 moves back and forth on the threaded rod 104 and can slide back and forth on the guide block 125. The support platforms 126 are located at both ends of the guide block 125 and the threaded rod 104. The vertical moving block 105 is slidably connected to the guide block 125. One end of the threaded rod 104 is connected to a drive assembly 127. The drive assembly 127 can be replaced with a motor drive or a drive device of the same type.

[0039] Specifically, refer to Figure 1 and Figure 2 The drive assembly 127 includes a turbine 128 and a worm 129 that cooperate with each other. The turbine 128 and the worm 129 have self-locking capabilities to prevent reversal when the threaded rod 104 is rotated. The turbine 128 is fixedly connected to the threaded rod 104. One end of the worm 129 is fixedly connected to a handwheel 130, which can drive the worm 129 to rotate through the handwheel 130. The handwheel 130 is rotatably connected to the support platform 126.

[0040] Specifically, refer to Figure 3 A positioning frame 131 is fixedly connected to the transverse frame 103. The length of the positioning frame 131 is the same as that of the transverse frame 103. The transverse moving block 107 can be fixed on it through the internal fixing bolt 132. The internal sliding connection of the positioning frame 131 is connected with a fixing bolt 132. The top of the fixing bolt 132 passes through the transverse moving block 107. By rotating the positioning nut 133, the distance between the positioning frame 131 and the transverse moving block 107 becomes smaller, thereby fixing them, and the top is threaded with a positioning nut 133.

[0041] Specifically, the angles of the two positioning holes 124 are the same as the angles at both ends of the sliding groove 112, and are located on the moving trajectory of the positioning beads 122. The positioning beads 122 enable the fixing claw 111 to have only two positions, one is parallel to the horizontal frame 103, and the other is parallel to the vertical frame 102.

[0042] Specifically, refer to Figures 4 to 6 The opposite side of the fixed claw 111 and the lower clamping claw 115 is installed with an anti-skid pad, which acts as a cushion to improve the anti-skid ability.

[0043] Specifically, the fastening handle 114 is provided with an eccentric hole and is hinged to the fixing rod 113 through the eccentric hole. By pressing the fastening handle 114, the distance between the fixing claw 111 and the fixing plate 110 becomes smaller, thereby fixing them together.

[0044] In this embodiment, the sealant to be tested for tensile strength is applied between two test blocks, and then the two test blocks are clamped on the clamping assemblies 108 on the vertical moving block 105 and the horizontal moving block 107 respectively. The clamping assembly 108 on the horizontal moving block 107 fixes one of the test blocks, and the hand wheel 130 is rotated. The hand wheel 130 drives the threaded rod 104 to rotate through the driving assembly 127. When the threaded rod 104 rotates, it drives the vertical moving block 105 to move, and the vertical moving block 105 drives the test block above to move. The test block coated with the sealant is pulled by the relative movement of the two clamping assemblies 108, so as to test its displacement tension parameter.

[0045] The fixed claw 111 inside the clamping assembly 108 can be rotated 90 degrees to perform a horizontal or oblique displacement tensile test. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the sealant oblique displacement test. Figure 2 This is a schematic diagram of the sealant lateral displacement test. When the direction of the fixing claw 111 is changed, the fastening handle 114 is bent upward. Because the fastening handle 114 is eccentrically set, the distance between the fixing claw 111 and the fixing plate 110 becomes larger, and the fastening handle 114 loses its fixing effect on the fixing claw 111. The fixing claw 111 can slide along the sliding groove 112. When the fixing claw 111 rotates, the positioning bead 122 at the bottom will be squeezed by the inner wall of the support frame 109, thereby being pressed into the mounting hole 120. The position of the other positioning hole 124 corresponds to the position of the sliding groove 112. When the fixing claw 111 moves to the other end of the sliding groove 112 through the fixing rod 113 at the top, the positioning bead 122 at the bottom will also enter the other positioning hole 124, thereby positioning the fixing claw 111 to prevent the fixing claw 111 from rotating out of place. Then, the fastening handle 114 is pressed down. After being pressed down, the gap between the fixing claw 111 and the clamping assembly 108 becomes smaller, thereby fixing the fixing claw 111;

[0046] When the test block needs to be fixed on the clamping assembly 108, the fastening nut 119 is rotated to allow the clamping bolt 117 to move downward. At this time, the gap between the fixed claw 111 and the lower clamping jaw 115 becomes larger, so that the test block can be placed in and placed between the symmetrical anti-slip pads. The symmetrical anti-slip pads act as a cushion. Then, the fastening nut 119 is rotated in the opposite direction. When the fastening nut 119 rotates, it drives the clamping bolt 117 to move upward, so that the distance between the fixed claw 111 and the lower clamping jaw 115 becomes smaller, thereby fixing the test block.

[0047] When adjusting the position of the vertical moving block 105 on the threaded rod 104, manually rotate the handwheel 130, the handwheel 130 drives the turbine 128 to rotate through the worm 129, and the turbine 128 drives the vertical moving block 105 to move in the vertical direction through the threaded rod 104. When it is necessary to adjust the horizontal position of the horizontal moving block 107, loosen the positioning nut 133 on the horizontal moving block 107, so that the fixing bolt 132 loses the ability to fix the horizontal moving block 107 on the positioning frame 131, thereby adjusting the horizontal position of the horizontal moving block 107, and fix it by rotating the positioning nut 133 in the opposite direction.

[0048] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
