Description

Technical Field

[0001] The present application relates to the technical field of production equipment clamping, and in particular to a threaded clamping handle. Background Art

[0002] When producing PCB equipment and some substrate equipment, a clamping handle is required to clamp the glass during installation to ensure the stability of the structure. The existing clamping handle is usually fixed by a base, and the base and the clamping handle are tightly connected, and a sealing ring is provided to ensure the sealing. However, the existing clamping handle still has some problems when in use. For example, the clamping handle is in direct contact with the glass, which causes slipping when the handle is rotated to open or close the glass, affecting the operating efficiency and user experience. Therefore, how to provide a clamping handle that can solve the above problems is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0003] In order to solve the problem that the clamping handle is prone to slipping when opening or closing the glass, the present application provides a threaded clamping handle.

[0004] The present application provides a threaded clamping handle, which adopts the following technical solution:

[0005] A threaded clamping handle is used to lock glass. The threaded clamping handle includes a synchronous rotation component and a positioning component. The positioning component passes through the glass from a first side of a positioning hole of the glass. The synchronous rotation component is screwed together with the positioning component from a second side of the positioning hole of the glass. The synchronous rotation component includes an inner fixing seat and an outer handle that are nested with each other. The inner fixing seat is synchronously rotationally connected to the outer handle. The inner fixing seat is embedded in the outer handle. The positioning component includes a locking piece and a plug-in piece. The locking piece is threadedly connected to the plug-in piece.

[0006] By adopting the above technical solution, the spiral cooperation between the synchronous rotating component and the positioning component can firmly fix the glass, the inner fixing seat is in contact with the glass, and there is a gap between the outer handle and the glass. In the process of pressing the glass, the outer handle does not directly contact the glass, which can reduce the wear of the outer handle on the glass during the rotation process, and the outer handle will not slip and hinder the rotation process.

[0007] Preferably, the connector further comprises a sealing ring, which is installed on a side of the connector close to the glass. The connector is provided with a mounting groove for mounting the sealing ring, and an upper surface of the sealing ring abuts against the first side of the glass.

[0008] By adopting the above technical solution, the movable connection between the connector and the sealing ring reduces the phenomenon of air leakage due to lack of compression when the sealing ring is loosened, and improves the air tightness and structural stability of the threaded compression handle.

[0009] Preferably, a protective cover for preventing impurities from entering is provided on the outer end surface of the inner fixing seat.

[0010] By adopting the above technical solution, the protective cover is located on the outer end surface of the inner fixing seat, and the port of the inner fixing seat is closed, so as to reduce the entry of impurities such as dust and water, thereby covering the positioning assembly, affecting the use of the positioning assembly, and improving the service life. Preferably, the inner end surface of the inner fixing seat is in contact with the glass, and the inner end surface of the outer handle is spaced from the glass. By adopting the above technical solution, when the outer handle starts to rotate, the inner fixing seat will also rotate accordingly to perform a pressing operation on the glass. The inner end surface of the inner fixing seat is in contact with the glass, which can better apply pressure to the glass. The inner end surface of the outer handle is spaced from the glass, which can better reduce the wear on the glass. Preferably, the outer surface of the outer handle is provided with anti-skid patterns. By adopting the above technical solution, the setting of the anti-skid patterns increases the friction force and facilitates the pressing operation. Preferably, the outer handle is provided with a handle position. By adopting the above technical solution, the setting of the handle position is convenient for gripping. Preferably, a protective plate is provided on the side of the outer handle close to the glass, and the protective plate is fixedly connected to the outer handle.

[0011] By adopting the above technical solution, the provision of the protection plate can increase the area in contact with the glass and better apply pressure.

[0012] Preferably, the protection plate has a gradually varying thickness.

[0013] By adopting the above technical solution, the gradient thickness can better distinguish the direction of rotation, is ergonomic, and better bears force during rotation.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. The inner fixing seat is in contact with the glass, and there is a gap between the outer handle and the glass. During the process of pressing the glass, the outer handle does not directly contact the glass, which can reduce the wear of the outer handle on the glass during the rotation process, and the outer handle will not slip and hinder the rotation process.

[0016] 2. The handle is easy to hold. 3. The protective plate can increase the area in contact with the glass and better apply pressure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-2 This application is described in further detail.

[0021] The present application embodiment discloses a threaded clamping handle. Figure 1 and Figure 2 A threaded clamping handle is used to lock the glass. The threaded clamping handle includes a synchronous rotation component 1 and a positioning component 2. The positioning component 2 passes through the glass from the first side of the positioning hole of the glass. The synchronous rotation component 1 is screwed with the positioning component 2 from the second side of the positioning hole of the glass, so that the glass can be firmly fixed. The synchronous rotation component 1 includes an inner fixing seat 11 and an outer handle 12 which are nested with each other. The inner fixing seat 11 is synchronously rotated with the outer handle 12, and the inner fixing seat 11 is embedded in the outer handle 12. The inner end surface of the fixing seat abuts against the glass, and there is a gap between the inner end surface of the outer handle 12 and the glass. In the process of clamping the glass, the outer handle 12 does not directly contact the glass, which reduces the wear of the outer handle 12 on the glass during the rotation process, and the outer handle 12 will not slip during the rotation process to hinder the rotation process. The outer surface of the outer handle 12 is provided with an anti-slip pattern 121, which can increase the friction and facilitate the clamping operation.

[0022] The positioning assembly 2 includes a locking member 21 and a plug-in member 22. The locking member 21 is located on the inner surface of the inner fixing seat 11. The locking member 21 passes through the positioning hole of the glass and is connected to the plug-in member 22. The locking member 21 and the plug-in member 22 can be connected by a thread, a snap-on connection, or a connection member. Any function that can realize the movable connection of the positioning assembly 2 is acceptable.

[0023] Before the glass is pressed, the synchronous rotating assembly 1 is first connected to the positioning assembly 2 through the positioning hole of the glass. During the pressing process, the force is transmitted from the handle position 122 of the outer handle 12 to the inner surface of the outer handle 12. Since the outer handle 12 is tightly matched with the inner fixed seat 11, the inner fixed seat 11 begins to rotate in the direction of the external force under the action of the force. At this time, the locking member 21 located on the inner surface of the inner fixed seat 11 is interference fit with the raised block on the inner surface of the inner fixed seat 11. Under the action of the force, the locking member 21 begins to rotate. The locking member 21 and the plug-in member 22 approach each other under the action of the external force. The protective plate 123 also presses against the glass with the action of the force, thereby pressing the glass. The first side of the glass is tightly fitted with the sealing ring 221 in the locking member 21. Since the sealing ring 221 is squeezed and deformed under the action of the force, it is firmly attached to the glass, thereby improving the air tightness.

[0024] Reference Figure 2 , a mounting groove 222 is provided on one end of the connector 22 close to the glass, and the mounting groove 222 is used to install the sealing ring 221. The diameter of the mounting groove 222 is consistent with the diameter of the sealing ring 221. During the pressing process, the deformation diameter of the sealing ring 221 is squeezed to exceed the diameter of the mounting groove 222, so that the airtightness of the glass is better. The diameter of the mounting groove 222 can also be smaller than the diameter of the sealing ring 221. In the pressed state, the deformation amount of the sealing ring 221 is much greater than the diameter of the sealing ring 221, and its sealing effect is also greater than the effect of the mounting groove 222 and the sealing ring 221 having the same diameter.

[0025] Reference Figure 2 The outer end surface of the inner fixing seat 11 is provided with a protective cover 111 for preventing impurities from entering. The protective cover 111 is connected to the inner fixing seat 11 by a snap-fit ​​connection or a threaded connection. The port of the inner fixing seat 11 is closed, and the locking member 21 is covered to prevent dust, water and other impurities from entering and affecting the service life. The protective plate 123 and the outer handle 12 are designed as an integrated whole, and the protective plate 123 has a gradual thickness, which can better distinguish the rotation direction, better bear the force during the rotation process, and also save materials.

[0026] The implementation principle of a threaded clamping handle in an embodiment of the present application is: the spiral cooperation between the synchronous rotating component 1 and the positioning component 2 can firmly fix the glass, the inner fixing seat 11 is in contact with the glass, and there is a gap between the outer handle 12 and the glass. In the process of clamping the glass, the outer handle 12 does not directly contact the glass, which can reduce the wear of the outer handle 12 on the glass during the rotation process, and the outer handle 12 will not slip off and hinder the rotation process.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
