Description

Technical Field

[0001] This utility model relates to the field of testing fixtures, and in particular to a sample preparation mold that facilitates the peel strength test of pre-laid waterproof membrane. Background Technology

[0002] Pre-applied waterproof membrane is a material used for waterproofing buildings, typically pre-laid on the surface of concrete structures. This type of membrane has excellent waterproofing properties, effectively preventing water penetration and protecting building structures from water damage.

[0003] A Chinese patent discloses an integrated fixture suitable for peel strength testing and sample preparation of pre-laid waterproof membranes (authorization announcement number CN 113405987 B). This patented technology can directly produce concrete samples and seamlessly connect to the peel strength test of pre-laid waterproof membranes, eliminating the need for moving and clamping concrete samples to the testing fixture after sample preparation, simplifying the experimental process and improving the accuracy of experimental results. However, the dimensions of its U-shaped frame, limiting baffle, and load-bearing plate are fixed, while the size and specifications of the pre-laid waterproof membranes may vary. If the testing device cannot be adjusted, it may not be able to adapt to different sizes of membranes, resulting in a limited testing range.

[0004] Therefore, this utility model provides a sample preparation mold that facilitates the peel strength test of pre-laid waterproof membrane. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sample preparation mold that facilitates the peel strength test of pre-laid waterproof membrane.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sample preparation mold for facilitating the peel strength test of pre-laid waterproof membrane, comprising: a support frame and a moving component; the moving component includes a gear slidably connected to the support frame, and a synchronous adjustment component is fixedly connected to the top of the moving component;

[0007] A limiting component; the limiting component includes a support ring fixedly connected to the outside of the gear, the support ring being rotatably connected to a ratchet, and a pawl fixedly connected to one side of the top of the support ring;

[0008] The engaging assembly includes connecting rods fixedly connected to both sides of a support ring. A slider is fixedly connected to the end of the connecting rod away from the support ring. A positioning plate is fixedly connected to one side of the slider. Moving columns are slidably connected to both ends inside the positioning plate. A spring is sleeved on the outside of the moving column. A locking block is fixedly connected to the bottom end of the moving column. A base plate is fixedly connected to the end of the slider near the locking block.

[0009] In a preferred embodiment, a rack is fixedly connected to one side of the top end of the support frame, and a slide rail is fixedly connected to the other side of the top end of the support frame, with the slider internally slidably connected to the slide rail.

[0010] 3. In a preferred embodiment, the synchronization adjustment assembly includes a handle fixedly connected to the top of the gear, a connecting rod fixedly connected to the outside of the handle, and a grip fixedly connected to the outside of the connecting rod.

[0011] In a preferred embodiment, the ratchet and the pawl are engaged.

[0012] In a preferred embodiment, one end of the spring is fixedly connected to the movable column, and the other end of the spring is fixedly connected to the positioning plate.

[0013] In a preferred embodiment, the gear and rack are meshed together.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this invention, when the pre-laid waterproof membrane is locked and fixed by the locking assembly, the moving column slides inside the positioning plate, and the spring is compressed or stretched, storing elastic potential energy. When the moving column slides to the appropriate position, the spring releases the elastic potential energy, pushing the moving column back to the initial position, thereby causing the locking block to extend and lock with the base plate. This design achieves adaptability to pre-laid waterproof membranes of different sizes and specifications, ensuring that the membrane can be stably maintained in the predetermined position during sample preparation, thus improving the accuracy and reliability of the experiment.

[0016] 2. When the moving component moves to the predetermined position, the pawl engages with the ratchet, preventing the ratchet from rotating in the opposite direction, thereby limiting the reverse rotation of the gear and ensuring the stability of the moving component's position. This design achieves stable fixation of the mold position, preventing errors caused by mold position changes during sample preparation, improving the accuracy and reliability of the experiment, and allowing for rapid release of the roll material, facilitating the handling and storage of the roll material after the experiment, thus improving the convenience of the experiment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a sample preparation mold for facilitating the peel strength test of pre-laid waterproof membrane, including: a support frame 1 and a moving component 2; the moving component 2 includes a gear 21 slidably connected to the support frame 1, a rack 22 fixedly connected to one side of the top of the support frame 1, the gear 21 and the rack 22 being meshed, and a slide rail 23 fixedly connected to the other side of the top of the support frame 1, and a slider 24 being slidably connected to the slide rail 23 inside;

[0029] The support frame 1 serves as the basic support structure for the entire sample preparation mold, providing a stable installation platform and support force for other components. The gear 21 meshes with the rack 22, and the rack 22 moves linearly by rotating, thereby enabling the moving component 2 to move on the support frame 1. The rack 22 meshes with the gear 21, converting the rotational motion of the gear 21 into its own linear motion. The slide rail 23 provides a linear sliding track for the slider 24. The slider 24 cooperates with the slide rail 23 through its internal sliding connection structure to achieve its own sliding on the slide rail 23.

[0030] like Figure 1 - Figure 3 As shown, the limiting component 3 includes a support ring 31 fixedly connected to the outside of the gear 21, a ratchet 32 ​​rotatably connected to the support ring 31, and a pawl 33 fixedly connected to one side of the top of the support ring 31. The ratchet 32 ​​and the pawl 33 are meshed.

[0031] The support ring 31 serves as a support and connector. It ensures that the ratchet 32 ​​can rotate stably on the support ring 31, and the ratchet 32 ​​engages with the pawl 33. Through its engagement with the pawl 33, it restricts rotation to one direction only, preventing reverse rotation. The pawl 33 also engages with the ratchet 32. Its main function is to prevent the ratchet 32 ​​from rotating in the opposite direction. When the gear 21 needs to rotate, the pawl 33 slides on the back of the ratchet 32 ​​teeth, not hindering its rotation; when the gear 21 does not need to rotate, the pawl 33 engages with the ratchet 32 ​​teeth, preventing reverse rotation, thus limiting the rotation of the gear 21. When adjusting the pawl 33, removing its restriction on the ratchet 32 ​​allows the gear 21 to rotate freely.

[0032] like Figure 1 - Figure 3 As shown, the engaging assembly 4 includes connecting rods 41 fixedly connected to both sides of the support ring 31. A slider 24 is fixedly connected to the end of the connecting rod 41 away from the support ring 31. A positioning plate 42 is fixedly connected to one side of the slider 24. Moving columns 43 are slidably connected to both ends inside the positioning plate 42. A spring 44 is sleeved on the outside of the moving column 43. One end of the spring 44 is fixedly connected to the moving column 43, and the other end of the spring 44 is fixedly connected to the positioning plate 42. A locking block 45 is fixedly connected to the bottom end of the moving column 43. A base plate 46 is fixedly connected to the end of the slider 24 near the locking block 45.

[0033] The connecting rod 41 serves as a connection and support, linking the support ring 31 and the slider 24 together. This allows the slider 24 to move in tandem with the support ring 31 via the connecting rod 41, thereby achieving the overall movement and positioning function of the engaging assembly 4. The positioning plate 42 provides a sliding track and support for the moving column 43. The main function of the moving column 43 is to extend and retract the locking block 45 through its own sliding, thus completing the engaging and disengaging actions. The spring 44 provides elastic support to the moving column 43, enabling it to automatically reset during sliding. When the moving column 43 slides under external force, the spring 44 is compressed or stretched, storing elastic potential energy; when the external force disappears... Spring 44 releases elastic potential energy, pushing the moving column 43 back to its initial position, thereby realizing the automatic reset function of the locking block 45. The function of the locking block 45 is to position and fix the pre-laid waterproof membrane by engaging with the base plate 46. When the moving column 43 slides, the locking block 45 will extend or retract accordingly, thereby completing the engagement or disengagement action. The shape and size design of the locking block 45 enable it to fit tightly with the corresponding slot or hole, ensuring that the mold can be stably maintained in the predetermined position during use. The base plate 46 provides support and positioning reference for the locking block 45. The base plate 46 is fixedly connected to the slider 24, so that the locking block 45 has a stable support surface when engaging, ensuring the accuracy of engagement.

[0034] like Figure 1 and Figure 4 As shown, a synchronization adjustment component 5 is fixedly connected to the top of the moving component 2. The synchronization adjustment component 5 includes a handle 51 fixedly connected to the top of the gear 21, a connecting rod 52 fixedly connected to the outside of the handle 51, and a grip 53 fixedly connected to the outside of the connecting rod 52.

[0035] The handle 51 is the part that the operator directly operates. By turning the handle 51, the gear 21 can be rotated, and then the movement of the moving component 2 can be achieved through the meshing transmission between the gear 21 and the rack 22. The connecting rod 52 serves to connect the handle 51 and the grip 53 together, so that when the operator turns the handle 51, the force can be transmitted to the grips 53 at both ends through the connecting rod 52. The grip 53 is the part that the operator holds. By holding the grip 53, the operator can turn the handle 51 more stably.

[0036] like Figure 1 - Figure 4 As shown:

[0037] In use: First, when the pre-laid waterproof membrane is locked in place, the movable column 43 slides inside the positioning plate 42, and the spring 44 is compressed or stretched, storing elastic potential energy. When the movable column 43 slides to the appropriate position, the spring 44 releases the elastic potential energy, pushing the movable column 43 back to the initial position, thereby causing the locking block 45 to extend and engage with the base plate 46, thus achieving the positioning and fixing of the pre-laid waterproof membrane. Then, the operator turns the handle 51, which in turn drives the gear 21 to rotate, thereby driving the rack 22 meshing with the gear 21 to advance. The linear motion drives the moving component 2 to move on the support frame 1, achieving precise adjustment of the mold position. When the moving component 2 moves to the predetermined position, the pawl 33 engages with the ratchet 32, preventing the ratchet 32 ​​from rotating in the opposite direction, thereby limiting the reverse rotation of the gear 21 and ensuring the stability of the moving component 2, thus realizing the positioning function of the mold. When it is necessary to release the engagement, the moving column 43 slides under the action of external force, and the locking block 45 retracts, thereby releasing the fixation of the pre-laid waterproof membrane and realizing the release function of the engaging component 4.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
