Description

Technical Field

[0001] This utility model relates to the field of filter cloth installation structure technology, and in particular to a filter cloth clamping structure with disassembly and assembly protection. Background Technology

[0002] Filter cloth is commonly used in plate and frame filter presses or bag filters, and its materials include polyester, polypropylene, and nylon. During installation, filter cloth is typically secured to the filter plate using clamping structures such as clips, pressure strips, or bolts.

[0003] Existing pressure strip structures are typically made of elastic steel. The pressure strip is snapped into the upper and lower surfaces of the frame plate at both ends. Utilizing the flexibility of the steel, the pressure strip presses onto the filter cloth, thus securing it in place. During assembly and disassembly, one end of the pressure strip is usually removed from the frame plate first, followed by pulling out the other end. However, precisely because of the pressure strip's elastic deformation, when one end is removed, the strip is compressed and elastically breaks open. This broken end can easily strike the technician, causing injury.

[0004] Therefore, this utility model provides a filter cloth clamping structure with disassembly protection to improve the safety when removing the pressure strip. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a filter cloth clamping structure with disassembly and assembly protection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The filter cloth clamping structure with disassembly protection includes a pole and elastic clamps at both ends of the pole. The center of the pole has a tension structure that can be elastically deformed. The upper elastic clamp is rotatably connected to the pole, and a limiting component is provided between the elastic clamp and the pole. The limiting component ensures that the elastic clamp and the pole are fixed only in the vertical position.

[0008] Preferably, the limiting component includes a support seat disposed at the upper end of the upright and a rotating head disposed at the upper elastic clip mounting end. The rotating head is rotatably mounted on the support seat, the rotating head extends outward and the extended part is provided with a limiting hole, and a buckle that cooperates with the limiting hole is rotatably mounted on the support seat.

[0009] Preferably, a collar is rotatably mounted on the support, and a latch is disposed on the collar.

[0010] Preferably, a retaining shaft is fixed on the support, and a collar is sleeved on the retaining shaft.

[0011] Preferably, the end of the retaining shaft is threaded with a nut that abuts against the collar.

[0012] Preferably, the outer edge of the collar is provided with a handle.

[0013] Preferably, a torsion spring is provided between the collar and the support.

[0014] Preferably, the top view projection of both elastic clips is triangular.

[0015] Preferably, one side of the lower elastic clip head is provided with an upward-curving hook.

[0016] Preferably, both the elastic clip and the upright are made of high-strength and high-toughness materials.

[0017] Compared with the prior art, this utility model provides a filter cloth clamping structure with detachable protection, which has the following beneficial effects:

[0018] This invention utilizes the elastic tension generated by the upright and tension structure under pressure to press against the filter cloth, thereby achieving filter cloth insertion. During disassembly, the limiting component between the upper elastic clip and the upper end of the upright is adjusted. The upper elastic clip rotates relative to the upper part under force, thereby counteracting the elastic force of the upright's elastic deformation and preventing the upright from breaking open and hitting personnel, thus improving disassembly safety.

[0019] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught by practice of this invention.

[0030] The following will refer to the appendix in the embodiments of this utility model. Figure 1-9 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0031] Example 1: To prevent the pressure strip from breaking open due to elasticity during disassembly and causing personal injury, this example provides a filter cloth clamping structure with disassembly protection, including a vertical rod 1 and elastic clamps 2 set at both ends of the vertical rod 1.

[0032] Both the elastic clip 2 and the upright 1 are made of high-strength and tough materials, such as alloy spring steel and high-strength stainless steel.

[0033] The upright pole 1 is integrally formed from a single steel bar of high strength and toughness, as shown in the attached figure. Figure 1 The enlarged view shows that the steel bar is twisted once at the center to form a tension structure 12 that can be elastically deformed. This tension structure 12 gives the pressure bar good resistance to bending and the ability to recover after bending deformation.

[0034] The upper elastic clip 2 is rotatably connected to the upright 1, and a limiting component is provided between the elastic clip 2 and the upright 1. The limiting component ensures that the elastic clip 2 and the upright 1 are fixed only in the vertical position.

[0035] Based on the above technical solution:

[0036] During installation, the upper elastic clip 2 is kept vertically integrated with the upright 1 by using the limiting component. Then, the upper elastic clip 2 is first inserted into the frame plate, and then pulled upwards, causing the lower elastic clip 2 to rise above the locking part below the frame plate. Next, the lower elastic clip 2 is inserted into the frame plate. Afterwards, the locking structure is adjusted to a suitable position, thus completing the installation of one locking structure. (Refer to the attached diagram.) Figure 9As shown. Two elastic clips 2 limit the vertical position of the upright 1, and the upright 1 abuts against the filter cloth. The tension structure 12 of the upright 1 is used to achieve tension deformation of the upright 1 under force, generating elastic force, thereby squeezing the filter cloth and making the filter cloth stably embedded in the frame plate.

[0037] During disassembly, first adjust the limiting component so that it separates from the upper elastic clip 2, and the upper elastic clip 2 loses its limiting function; while the upright 1 rotates relative to the upper elastic clip 2 under the reverse squeezing action of the filter cloth, thereby counteracting the elastic deformation of the upright 1. At this time, the two elastic clips can be removed from the frame plate respectively.

[0038] This solution utilizes the elastic tension generated by the upright rod 1 and tension structure 12 under pressure to press against the filter cloth, thereby achieving filter cloth installation. For disassembly, refer to the attached... Figure 8 Right side view and appendix Figure 9 As shown, the upper elastic clip 2 and the limiting piece between the upper end of the upright 1 are adjusted so that the upper elastic clip 2 rotates relative to each other, thereby counteracting the elastic force of the upright 1's elastic deformation. After the elastic force dissipates, the elastic clip 2 can be removed at this time, and there will be no problem of the elastic force breaking and hitting people.

[0039] In this embodiment, the top view projection of both elastic clips 2 is triangular. The plane of the triangle is used as the part that fits against the inner wall of the frame plate, serving as an embedded support point to ensure the stability of the upright 1 and prevent it from deflecting on its own. The triangle is not closed, leaving room for deformation of the upright 1 under bending force.

[0040] In this embodiment, one side of the lower elastic clip 2 is provided with an upward-curving hook 13. This allows for upward pulling during assembly and disassembly, separating the lower elastic clip 2 from the lower side wall of the frame plate.

[0041] Example 2, a further embodiment of this solution, refers to the appendix. Figure 2-5 As shown, the limiting component includes a support 3 integrally formed with the upper end of the upright 1 and a rotating head 4 mounted on the upper end of the elastic clip 2. The support 3 has two supports, each detachably fitted with a rotating shaft (such as a pin or bolt). The rotating head 4 has a transition hole that fits onto the rotating shaft, allowing the rotating head 4 to be rotatably mounted on the support 3. The rotating head 4 extends outward from the side opposite the filter cloth, and the extended portion has a limiting hole 5. A latch 6, which mates with the limiting hole 5, is rotatably mounted on the support 3. The latch 6 can be any of the following shapes: arc-shaped, C-shaped, V-shaped, or 7-shaped.

[0042] Based on the above technical solution:

[0043] During disassembly, rotate the buckle 6, and the end of the buckle 6 separates from the limiting hole 5. At this time, the upper elastic clip 2 is only connected to the support 3 by rotating the head 4, so that it deflects under the rebound force of the filter cloth to eliminate the rebound force of the deformation of the upright 1.

[0044] In this embodiment, the side of the rotating head 4 that is in contact with the filter cloth does not exceed the outer wall of the upright 1, so as to avoid the rotating head 4 being obstructed and causing a delay in the elimination of elasticity.

[0045] In this embodiment, a collar 7 is rotatably mounted on the support 3, and a buckle 6 is disposed on the collar 7 to complete the rotatable installation of the buckle 6.

[0046] In this embodiment, a retaining shaft 9 is fixed on the support 3, and a collar 7 is sleeved on the retaining shaft 9. This provides a mounting base for the rotational installation of the latch rod 6.

[0047] In this embodiment, a nut 8 is threaded onto the end of the retaining shaft 9 and abuts against the collar 7. This makes the collar 7 and the fastener detachable and easy to replace if deformed.

[0048] In this embodiment, the outer edge of the collar 7 is provided with a handle 11 for easy rotation of the fastener.

[0049] In this embodiment, a torsion spring 10 is provided between the collar 7 and the support 3. (Refer to the attached diagram.) Figure 5 As shown, a limiting shaft one is located above the retaining shaft 9 on the support 3, and a limiting shaft two is located below the retaining shaft 9 on the side of the handle 11 facing the support 3. A torsion spring 10 is sleeved on the collar 7, with one protruding end of the torsion spring 10 abutting against the limiting shaft one and the other protruding end abutting against the limiting shaft two, thus completing the installation of the torsion spring 10. The torsion spring 10 provides a constant counterclockwise driving force to the collar 7. Although the fastener will not easily detach under force after being inserted into the limiting hole 5, the counterclockwise force applied by the torsion spring 10 ensures that the fastener is tightly fastened to the rotating head 4, preventing easy separation and improving the tightness and stability of the connection between the fastener and the rotating head 4.
