Description

Technical Field

[0001] This application relates to the technical field of building material testing, and particularly relates to a pressure test device. Background Art

[0002] A pressure test device is an instrument used to conduct pressure tests on various building materials. Existing pressure testing machines include a machine body, a lower pressure bearing seat, and an upper pressure bearing seat. The lower pressure bearing seat and the upper pressure bearing seat are installed on the machine body, and a space for placing a specimen is formed between them. By driving the relative movement of the lower pressure bearing seat and the upper pressure bearing seat to squeeze the specimen, the pressure that the specimen can withstand is measured.

[0003] During the extrusion process of the specimen, the specimen will break and cause some debris to scatter everywhere, making subsequent cleaning more troublesome. Utility Model Content

[0004] In order to improve the convenience of cleaning debris, this application provides a pressure test device.

[0005] This application provides a pressure test device, adopting the following technical solution:

[0006] A pressure test device includes a frame, a lower pressure bearing seat and an upper pressure bearing seat installed on the frame. A placement space is formed between the lower pressure bearing seat and the upper pressure bearing seat, and further includes:

[0007] A base, including a main body part and a material guiding part. The main body part surrounds the lower pressure bearing seat on all sides, and the material guiding part is arranged on one side of the main body part and forms a material discharging channel extending away from the lower pressure bearing seat;

[0008] A shroud, arranged on the main body part, extending to face the upper pressure bearing seat, and the shroud forms a material feeding port opposite to the material guiding part. The material feeding port is opposite to and communicates with the placement space; and

[0009] A baffle member, hinged to the frame, capable of rotating to face or away from the material feeding port. When the baffle member faces the material feeding port, the shroud and the baffle member jointly enclose the placement space.

[0010] By adopting the above technical solution, the placement space is jointly enclosed by the baffle member and the shroud to limit the falling range of the debris between the baffle member and the shroud, so as to reduce the distribution range of the debris. Then, the debris is concentrated in the material discharging channel of the material guiding part to further concentrate the debris, thereby improving the convenience of cleaning the debris.

[0011] Optionally, the material guiding part extends downward along the direction away from the lower pressure bearing seat.

[0012] By adopting the above technical solution, the material guiding part extends downward to give the crushed slag in the material guiding part a downward falling trend. An aggregate container is placed below the material guiding part, and the crushed slag in the material guiding part can be guided to automatically fall into the aggregate container, thereby further improving the efficiency of collecting the crushed slag.

[0013] Optionally, an inner side of the main body part near the lower pressure bearing seat is recessed to form a material receiving groove, and the material receiving groove is communicated with the material discharging channel.

[0014] By adopting the above technical solution, the formation of the material receiving groove facilitates the concentration of the crushed slag between the shroud and the lower pressure bearing seat in the material receiving groove to concentrate the crushed slag falling on the main body part.

[0015] Optionally, a bottom height of the material receiving groove at the position of the main body part gradually decreases in a direction close to the material guiding part.

[0016] By adopting the above technical solution, the change in the bottom height of the material receiving groove can guide the crushed slag in the material receiving groove, so that the crushed slag automatically rolls into the material discharging channel of the material guiding part.

[0017] Optionally, a limiting part is provided on a side of the material blocking part away from its hinge point. When the material blocking part rotates to face the feeding port, the material blocking part is relatively positioned with the frame through the limiting part.

[0018] By adopting the above technical solution, the cooperation between the limiting part and the frame improves the stability of the material blocking part.

[0019] Optionally, the shroud is made of a material that can be bent and deformed.

[0020] By adopting the above technical solution, when the shroud abuts against the frame, it can be bent and deformed by itself, so that the shroud is not likely to hinder the relative movement between the upper and lower pressure bearing seats. And the shroud can be bent and deformed to facilitate the shroud to fit and adapt to the main body part.

[0021] Optionally, the shroud is bonded to the base.

[0022] Optionally, a connecting seat is connected to an outer wall of the main body part, a space for the shroud to extend into is provided between the connecting seat and the main body part, and a positioning part for pressing the shroud against the outer wall of the main body part is provided on the connecting seat.

[0023] By adopting the above technical solution, the positioning part is separated from the shroud so that the shroud can be removed from between the connecting seat and the main body part, thereby disassembling the shroud to facilitate taking out the shroud for cleaning or replacement.

[0024] Optionally, the positioning part includes

[0025] a moving rod, which is threadedly inserted into the connecting seat in a direction close to or away from the main body part;

[0026] An abutment seat, rotated on one end of the moving rod close to the main body;

[0027] A movable seat, slidingly moving on a side of the abutment seat toward the main body along a moving direction of the movable rod;

[0028] A ball bearing rotates on a side of the movable seat facing the main body; and

[0029] An elastic portion, connected between the movable seat and the abutting seat, and used to give the movable seat a tendency to move out of the abutting seat on the side close to the main body;

[0030] Wherein, the abutting seat has a receiving groove for allowing the moving seat to slide and accommodating the moving seat and the ball.

[0031] By adopting the above technical solution, the moving rod thread is first moved until the ball and the enclosure are butted against each other to pre-position the enclosure, and the enclosure can be pulled to adjust the enclosure position, and the movement of the enclosure drives the ball to rotate. After the enclosure position is adjusted, the moving rod thread is moved until the abutment seat is tightly abutted against the enclosure to further position the enclosure, so that the enclosure cup is positioned and clamped between the main body and the abutment seat.

[0032] In summary, the present application includes at least one of the following beneficial effects:

[0033] 1. Rotate the material stopper to a position away from the loading port, and the sample can be placed in the storage space from the loading port. When the material stopper is rotated to a position opposite to the loading port, the enclosure and the material stopper together enclose the storage space to prevent the debris splashed when the sample is broken. The debris falls into the receiving trough and the material discharge channel and can be discharged from the material discharge channel, thereby reducing the distribution range of the debris and improving the convenience of cleaning the debris;

[0034] 2. The material blocking piece is positioned relative to the frame through a limiting piece so that the material blocking piece is not easy to move when resisting the slag, thereby improving the stability of the material blocking piece. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0041] The following will further elaborate on the present application in conjunction with the attached Figures 1-5 drawings.

[0042] Embodiment 1:

[0043] The embodiment of the present application discloses a pressure test device. Referring to Figure 1 and Figure 2 , the pressure test device includes a frame 1, a lower bearing seat 2, an upper bearing seat 3, a base 5, a shroud 7, and a material blocking part 9.

[0044] The frame 1 is in a frame shape, and an operation cavity is formed in the middle of the frame 1. Both the upper bearing seat 3 and the lower bearing seat 2 are in a disc shape and are installed in the frame 1. The upper bearing seat 3 is located above the lower bearing seat 2, and a placement space 4 for placing specimens is formed between the upper bearing seat 3 and the lower bearing seat 2. There is a power source at the bottom of the frame 1 to drive the lower bearing seat 2 to move upward, so that the upper bearing seat 3 and the lower bearing seat 2 jointly squeeze the specimen. The power source can be a hydraulic jack or a cylinder. The way of jointly squeezing the specimen by the upper bearing seat 3 and the lower bearing seat 2 is a prior art and will not be elaborated here.

[0045] Referring to Figure 2 , the base 5 includes a main body part 51 and a material guiding part 52. The main body part 51 is fixed to the outer peripheral wall of the lower bearing seat 2, and an inward depression is formed in the inner side of the main body part 51 close to the lower bearing seat 2 to form a receiving groove 10. The opening of the receiving groove 10 faces upward and extends along the circumferential direction of the lower bearing seat 2. The outer peripheral wall of the lower bearing seat 2 serves as one side wall of the receiving groove 10.

[0046] The material guiding part 52 is integrally formed on one side of the main body part 51 and is continuous with the main body part 51. The material guiding part 52 extends radially away from the lower pressure bearing seat 2 along the lower pressure bearing seat 2 and extends beyond the front side of the frame 1, and the material guiding part 52 is inclined downward along the direction away from the lower pressure bearing seat 2. The material guiding part 52 is formed with a blanking channel 6 that extends downward and obliquely together with the material guiding part 52, and the blanking channel 6 is communicated with the material receiving groove 10. Place an aggregate container (not shown in the figure) on the front side of the frame 1 and below the material guiding part 52 for collecting the broken materials falling in the material guiding part 52.

[0047] Referring to Figure 2 , the shroud 7 is in the shape of an arc sheet. The bottom of the shroud 7 is arranged on the main body part 51 and fits with the main body part 51 along the circumferential direction of the main body part 51. The gap formed between the shroud 7 and the lower pressure bearing seat 2 is opposite to and communicated with the material receiving groove 10. In this embodiment, the shroud 7 is adhesively bonded to the inner wall of the main body part 51 by glue.

[0048] The two opposite sides of the shroud 7 are respectively close to the two opposite sides of the material guiding part 52, so that a feeding port 8 is formed between the two opposite sides of the shroud 7 that are far away from each other. The feeding port 8 is opposite to and communicated with the material guiding part 52, and the feeding port 8 is used for placing and taking out the specimen. And the top of the shroud 7 extends upward to be opposite to the outside of the upper pressure bearing seat 3, so that the feeding port 8 extends to be opposite to the placement space 4. The feeding port 8 communicates the placement space 4 of the shroud 7 and the external environment of the shroud 7.

[0049] Referring to Figure 1 and Figure 2 , the material blocking member 9 is made of a transparent hard material, and the material blocking member 9 is in the shape of a plate with a middle part recessed outward. One side of the material blocking member 9 is hinged to one side of the frame 1 through a pin shaft, and the rotation axis of the hinged part of the material blocking member 9 extends vertically. The rotation of the material blocking member 9 relative to the frame 1 can make the material blocking member 9 located at the first position and the second position.

[0050] When the material blocking member 9 is located at the first position, the side of the material blocking member 9 away from its hinge point abuts against the frame 1, and the material blocking member 9 gives way to the lower pressure bearing seat 2 and the upper pressure bearing seat 3 through the recessed part. At this time, the material blocking member 9 is opposite to and close to the feeding port 8 and the shroud 7, so that the material blocking member 9 and the shroud 7 jointly enclose the placement space 4 between the upper pressure bearing seat 3 and the lower pressure bearing seat 2.

[0051] The side of the material blocking member 9 away from its hinge point rotates away from the feeding port 8, so that the material blocking member 9 is located at the second position. At this time, the material blocking member 9 is away from the feeding port 8, and there is no obstruction in front of the feeding port 8.

[0052] Before the pressure test, first turn the material blocking member 9 to the second position so that the specimen can be placed on the lower pressure bearing seat 2 from the feeding port 8, and then turn the material blocking member 9 to the first position.

[0053] When a pressure test is carried out, the lower bearing seat 2 moves upward, driving the base 5 and the shroud 7 to move upward together. The crushed slag from the crushed specimen is blocked by the shroud 7 and the material blocking member 9 and enters the material receiving groove 10 and the material discharging channel 6, and then falls from the material discharging channel 6 into the aggregate container for collection.

[0054] After the pressure test is completed, the slag still in the material receiving groove 10 is swept into the material discharging channel 6 and falls out from the material discharging channel 6.

[0055] Refer to Figure 2 Furthermore, the shroud 7 is made of a material that can be bent and deformed and has a certain hardness, such as kraft paper, plastic waterproof cloth, aluminum sheet, etc., and is preferably plastic waterproof cloth. When the shroud 7 is in the operation cavity, it can maintain an extended state through its own hardness. When the lower bearing seat 2 drives the shroud 7 to move upward and the shroud 7 contacts the frame 1, the shroud 7 is pressured by the frame 1 and can be bent and deformed, so that the shroud 7 does not hinder the movement of the lower bearing seat 2, enabling the upper bearing seat 3 and the lower bearing seat 2 to extrude specimens of different thicknesses.

[0056] To improve the convenience of material discharging, the bottom height of the main body part 51 at the material receiving groove 10 gradually decreases towards the guiding part 52, so as to guide the crushed material in the material receiving groove 10, making the crushed material in the material receiving groove 10 tend to move towards the guiding part 52, facilitating the guiding of the crushed material into the material discharging channel 6.

[0057] To improve the stability of the material blocking member 9 in blocking materials during the test, a limiting member 11 is provided on the side of the material blocking member 9 away from its hinge point. The limiting member 11 relatively positions the material blocking member 9 and the frame 1 when the material blocking member 9 is blocking materials. Specifically, in this embodiment, the limiting member 11 includes a bolt threadedly inserted into the material blocking member 9, and a limiting groove 15 for inserting the rod part of the bolt is provided on the side of the frame 1 away from the hinge point of the material blocking member 9. When the material blocking member 9 rotates to face the feeding port 8, the bolt is threadedly moved to insert the rod part of the bolt into the limiting groove 15 to limit the rotation of the material blocking member 9 and improve the stability of the material blocking member 9. In other embodiments, the limiting member 11 can also be a magnet installed on the side of the material blocking member 9 away from its hinge point, magnetically attracting the material blocking member 9 to the frame 1 to make the material blocking member 9 not easily rotate.

[0058] The implementation principle of a pressure test device according to an embodiment of the present application is as follows: After placing the specimen on the lower bearing seat 2, the material blocking member 9 is rotated to block the front side of the placement space 4. Then the lower bearing seat 2 moves upward to jointly extrude the specimen with the upper bearing seat 3. The crushed slag splashed when the specimen is crushed is jointly blocked by the shroud 7 and the material blocking member 9, so that the crushed slag falls into the material receiving groove 10 and the material discharging channel 6, and the crushed slag falls into the aggregate container placed in front of the frame 1 through the material discharging channel 6 for collection.

[0059] Embodiment Two:

[0060] The difference between the embodiment of the present application and the first embodiment lies in the different installation methods of the shroud 7. The embodiment of the present application discloses a pressure test device. Refer to Figure 3 , the pressure test device further includes a connecting seat 12, the connecting seat 12 is fixed on the outer wall of the main body part 51 and extends along the circumferential direction of the main body part 51. A space for placing the shroud 7 is formed between the connecting seat 12 and the outer wall of the main body part 51, and a plurality of positioning members 13 are fixed along the circumferential direction of the connecting seat 12. The positioning members 13 are used to press the shroud 7 against the outer wall of the main body part 51 for installing the main body part 51.

[0061] Refer to Figure 3 and Figure 4 , specifically, at the installation position of each positioning member 13 on the connecting seat 12, an installation part 16 cooperating with the positioning member 13 is formed. The installation part 16 is in a block shape and has an installation cavity 17 with an opening facing the outer wall of the main body part 51.

[0062] Refer to Figure 4 and Figure 5 , each positioning member 13 includes a moving rod 131, an abutting seat 132, a moving seat 133, a ball 134 and an elastic part 135.

[0063] The moving rod 131 is threadedly inserted into the installation part 16, and one end of the moving rod 131 close to the main body part 51 enters the installation cavity 17. The abutting seat 132 is in a square shape and rotates on one end of the moving rod 131 close to the main body part 51, and the abutting seat 132 is located in the installation cavity 17. The outer walls of the upper and lower ends of the abutting seat 132 are both abutted against the inner wall of the installation part 16. The threaded movement of the moving rod 131 drives the abutting seat 132 to move in the installation part 16 towards or away from the main body part 51, and the abutting seat 132 is limited by the installation part 16 and will not rotate together with the moving rod 131.

[0064] The moving seat 133 slides along the axial direction of the moving rod 131 on the side of the abutting seat 132 facing the main body part 51. The ball 134 is embedded and rotates on the side of the moving seat 133 facing the main body part 51. The abutting seat 132 has a receiving groove 14 for the moving seat 133 to slide. When the moving seat 133 and the ball 134 are subjected to a pressure moving towards the moving rod 131, they can be completely retracted into the receiving groove 14.

[0065] The elastic part 135 is preferably a spring and is installed in the abutting seat 132. The opposite ends of the elastic part 135 are respectively connected to the moving seat 133 and the inner wall of the abutting seat 132. When the elastic part 135 is in a natural state, one side of the abutting seat 132 close to the main body part 51 extends out of the abutting seat 132, and when the abutting seat 132 is retracted into the receiving groove 14, the elastic part 135 is in a compressed state.

[0066] Refer to Figure 3 and Figure 4, when installing the shroud 7, first move the moving rod 131 away from the main body 51 so that there is a gap for the shroud 7 to be inserted between the ball 134 and the outer wall of the main body 51. Then place the shroud 7 between the ball 134 and the main body 51, and thread the moving rod 131 so that the ball 134 abuts the shroud 7 against the main body 51 to pre-position the shroud 7. After that, move and adjust the position of the shroud 7. When moving the shroud 7, the ball 134 is driven to rotate.

[0067] After the position adjustment of the shroud 7 is completed, then thread the moving rod 131 in the direction close to the main body 51 so that the abutting seat 132 gradually receives the moving seat 133 and the ball 134 in the receiving groove 14 until the side of the abutting seat 132 facing the main body 51 tightly abuts the shroud 7 to position the shroud 7 relative to the main body 51. In addition, by threading the moving rod 131 in the direction away from the main body 51, the abutting seat 132 and the ball 134 can be separated from the shroud 7 so that the shroud 7 can be removed.

[0068] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
