Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to a handle locking component. Background Art

[0002] The handles of doors and windows are used to open and close the doors and windows. The handles include a base, a shaft and a handle, which are installed with a transmission box. The transmission box is operated by holding the handle to rotate the internal shaft, thereby opening and closing the doors and windows. However, due to the simple operation, children can easily hold the handle and turn it, and the doors and windows can be easily opened by children, which cannot better protect the safety of children.

[0003] At present, a handle has a slide that can be inserted into the rotating shaft installed in the base, one end of the slide extends out of the base for people to operate, and an elastic structure for positioning the slide is installed between the slide and the base. When there are children at home, the slide can be pushed from one end to the other end to engage the rotating shaft, lock the rotating shaft, and achieve the effect of being unable to rotate the handle, so as to better protect the safety of children. However, since the two ends of the slide are positioned and fixed by the positioning elastic structure, the slide can change its position by pushing under a large force. Therefore, the slide is relatively unstable. In the case of large vibration or collision, the slide is easy to loosen and detach from the rotating shaft or embed into the rotating shaft, thereby changing the original state of the rotating shaft, which is not convenient for daily use. Utility Model Content

[0004] The utility model aims to provide a handle locking assembly to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solution adopted to solve the above technical problems is as follows: a handle locking assembly, comprising: a base, rotatably mounted with a rotating shaft; a locking block, slidably mounted on the base, the rotating shaft being provided with a limiting groove for the locking block to be embedded in, an elastic member being provided between the locking block and the base, the elastic member providing elastic force for embedding or extending the locking block into or out of the limiting groove; a shift block, slidably mounted on the base, the shift block being provided with an inclined surface, the locking block being provided with a convex ridge that conflicts with the inclined surface, the sliding of the shift block can push the locking block to be embedded in or out of the limiting groove, and when the convex ridge is separated from the inclined surface, a side of the locking block away from the rotating shaft conflicts with a side surface of the shift block.

[0006] This technical solution has at least the following beneficial effects: by sliding the shift block, under the mutual interference of the inclined surface and the convex ridge, the locking block can be pushed to overcome the elastic force of the elastic member and embed into the limiting groove, so that the shaft cannot rotate, and the locking effect is achieved. Moreover, the contact area between the inclined surface and the convex ridge surface is small, and the friction force when the two slide relative to each other is small, so that the force required for the shift block is small, which is convenient for operation, and the linkage between the shift block and the locking block is not easy to get stuck. In addition, in the locked state, the side of the locking block conflicts with the side of the shift block, and the locking block is restricted by the shift block and is not easy to move, which can resist greater vibration or collision, thereby improving the stability of the locking block when locked and ensuring the reliability of the locking.

[0007] As a further improvement of the above technical solution, a first clamping block is provided at one end of the locking block away from the rotating shaft, and a second clamping block is provided at one side of the shifting block close to the locking block, and the locking block and the shifting block can be connected by snapping the first clamping block and the second clamping block. In the locked state, the locking block and the shifting block are snap-connected by the first clamping block and the second clamping block, so that the locking block and the shifting block are not easy to slip due to vibration and the like, and the locking block is reduced from being separated from the shifting block restriction and restored to the open state under the action of the elastic member, and the reliability of the locking is further improved.

[0008] As a further improvement of the above technical solution, a boss is installed on one end of the shift block near the locking block, and the locking block is provided with a corner-cut groove, and the boss and the corner-cut groove are both formed with guide surfaces that are adapted to slide, and the guide surface is parallel to the inclined surface. When the shift block slides and pushes the locking block to fit into the limiting groove, the convex edge slides on the inclined surface, and the guide surface of the boss slides in adaptation with the guide surface of the side wall of the corner-cut groove, thereby ensuring the stability of the sliding of the locking block relative to the shift block and improving the linkage between the shift block and the locking block.

[0009] As a further improvement of the above technical solution, a positioning block is installed at one end of the locking block away from the rotating shaft, and a first positioning surface is provided on one side of the positioning block. When the locking block is inserted into the limiting groove, the first positioning surface abuts against the inclined surface. The first positioning surface can position and limit the moving position of the shift block, thereby ensuring the stability of the moving range of the shift block, and at the same time, when locked, it can also improve the stability of the position of the shift block.

[0010] As a further improvement of the above technical solution, a boss is installed at one end of the shift block near the locking block, and the boss is formed with a second positioning surface perpendicular to the inclined surface, and a third positioning surface perpendicular to the first positioning surface is provided on one side of the positioning block, and when the locking block is embedded in the limiting groove, the second positioning surface and the third positioning surface are slidably fitted. That is, in the locked state, the second positioning surface and the third positioning surface are slidably fitted, thereby limiting the relative movement of the shift block and the locking block perpendicular to the second positioning surface, which can further improve the stability of the relative connection between the shift block and the locking block.

[0011] As a further improvement of the above technical solution, a protrusion is installed on one side of the shift block, and the protrusion passes through the base, and a slide groove for the protrusion to slide is provided through the base. The protrusion can pass through the outside of the base, and by shifting the protrusion on the outside of the base, the shift block can be driven to slide, and at the same time, the aesthetics of the product can be improved.

The shift block and the locking block are respectively embedded in the transverse groove and the longitudinal groove, which also facilitates the installation, removal and replacement of the shift block and the locking block, improves the assembly efficiency, and thus improves the production efficiency. At the same time, the internal structure of the base is simple, which is easy to manufacture and can reduce the manufacturing cost.

[0013] As a further improvement of the above technical solution, the locking block is provided with a receiving cavity for receiving the elastic member, the bottom wall of the longitudinal groove is provided with a fixed block embedded in the receiving cavity, the two ends of the elastic member are respectively connected to the side wall of the receiving cavity and the fixed block, and the locking block is provided with an operating groove connected to the receiving cavity on the side away from the receiving cavity. During assembly, the elastic member can be placed in the receiving cavity first, and then a tool is used to extend the tool from the operating groove into the receiving cavity, and one end of the elastic member is pressed to leave a gap between the elastic member and the side wall of the receiving cavity for the fixed block to be embedded. When the locking block is embedded in the longitudinal groove, the fixed block can be smoothly embedded in the receiving cavity without interfering with the elastic member, and then the elastic member is connected to the fixed block by loosening the tool, so that the locking block and the elastic member can be installed, and the elastic member is between the locking block and the base, which ensures the stability and reliability of the elastic member.

[0014] As a further improvement of the above technical solution, the base is provided with interconnected transverse grooves and longitudinal grooves on both sides of the rotating shaft, and the rotating shaft is provided with at least two limiting grooves. Locking blocks and shifting blocks and corresponding parts can be installed on both sides of the base, so that the base can have a double locking effect, providing customers with a variety of choices. At the same time, it is not necessary to distinguish which end to install during assembly, which can improve assembly efficiency and facilitate automated assembly.

[0030] Reference Figure 1-8 A handle locking assembly includes a base 10, which is in the shape of a rectangular parallelepiped. A rotating shaft 11 is rotatably mounted in the middle of the base 10, and a square shaft 80 is mounted in the rotating shaft 11. A face cover 15 and a handle 16 are mounted on the side of the base 10 away from the unsealed portion, and one end of the handle 16 is connected to the rotating shaft 11. A cylinder is mounted on the side of the base 10 close to the handle, and the face cover 15 is embedded in the cylinder so that the face cover 15 is rotatably connected to the base 10. An elastic ring 17 is mounted between the face cover 15 and the handle 16, and the elastic ring 17 makes the face cover 15 and the base 10 contact and cover each other. When the handle locking assembly is mounted on doors and windows for use, the square shaft 80 is connected to structures such as a transmission box. By rotating the handle, the rotating shaft 11 can be driven to rotate, thereby driving the square shaft 80 to rotate, so as to drive structures such as the transmission box to realize the function of opening or closing the doors and windows.

[0031] A transverse groove 70 and a longitudinal groove 71 are provided at both ends of the base 10. The length direction of the transverse groove 70 is the same as the width direction of the base 10, and the length direction of the longitudinal groove 71 is the same as the length direction of the base 10. The transverse groove 70 is located at the end of the base 10, and the longitudinal groove 71 is located at one side of the base 10. The transverse groove 70 and the longitudinal groove 71 are connected, so that the transverse groove 70 and the longitudinal groove 71 are L-shaped as a whole. A shift block 30 is slidably installed in the transverse groove 70 along the width direction of the base 10, and a locking block 20 is slidably installed in the longitudinal groove 71 along the length direction of the base 10. Two limiting grooves 21 are evenly arranged on the outer peripheral side of the rotating shaft 11, and the cross section of the limiting groove 21 is triangular fan-shaped. After the locking block 20 slides, one corner of one end of the locking block 20 can be embedded in the limiting groove 21 to limit the rotation of the rotating shaft 11. In other embodiments, one, three or four locking blocks 20 can be provided on the outer peripheral side of the rotating shaft 11 according to the number of locking blocks 20 installed.

[0032] A receiving chamber 72 is provided on the side of the lock block 20 close to the base 10, and the receiving chamber 72 contains an elastic member 22. A fixing block 73 is installed on the bottom wall of the longitudinal groove 71, and the fixing block 73 is formed integrally with the base. When the lock block 20 is embedded in the longitudinal groove 71, the fixing block 73 is embedded in the receiving chamber 72. The elastic member 22 is a coil spring, one end of the coil spring presses against the fixing block 73, and the other end presses against the end wall of the receiving chamber 72, so that the fixing block 73 is kept at one end of the receiving chamber 72, and the lock block 20 can also keep the state of not being embedded in the limiting groove 21, that is, the open state. When the lock block 20 is pushed to overcome the elastic force of the coil spring and the lock block 20 is embedded in the limiting groove 21, the fixing block 73 compresses the coil spring and slides in the receiving chamber 72.

[0033] An operation slot 74 is provided on the side of the lock block 20 away from the base 10. The operation slot 74 is connected to the accommodating chamber 72, but the width of the operation slot 74 is smaller than the width or diameter of the coil spring, so that the coil spring will not pass through the operation slot 74. One end of the operation slot 74 close to the fixed block 73 corresponds to one end of the accommodating chamber 72 close to the fixed block 73. When installing the lock block 20, first put the coil spring into the accommodating chamber 72, then use a tool such as a screwdriver or a thin plate to penetrate the accommodating chamber 72 from the operation slot 74, press one end of the coil spring against the tool, move the tool to make a gap between the end of the coil spring and the side wall of the accommodating chamber 72, and then embed the lock block 20 into the longitudinal slot 71, so that the fixed block 73 can be easily embedded between the end of the coil spring and the side wall of the accommodating chamber 72, and then pull out the tool. After the coil spring is reset, one end of the coil spring abuts against the side wall of the accommodating chamber 72, and the other end abuts against the side wall of the fixed block 73, so that the installation of the lock block 20 and the coil spring can be completed. In other embodiments, the elastic member 22 may also be an arc-shaped elastic sheet, the two ends of which are respectively pressed against the fixed block 73 and the end wall of the accommodating cavity 72, and the elastic force generated by the bending elasticity of the arc-shaped elastic sheet is used to keep the locking block 20 in a state of not being embedded in the limiting groove 21, that is, in an open state.

[0034] A shift block 30 is slidably installed in the transverse groove 70. The shift block 30 is provided with an inclined surface 31 at one end close to the locking block 20. A convex ridge 32 is provided at one end of the locking block 20 away from the rotating shaft 11 and close to the shift block 30. The convex ridge 32 is a side edge of the locking block 20. The convex ridge 32 conflicts with the inclined surface 31. At this time, the end of the shift block 30 away from the inclined surface 31 conflicts with the end wall of the transverse groove 70, so that the locking block 20 and the shift block 30 are in a stable state. A protrusion 13 is provided on the side of the shift block 30 close to the base 10. The protrusion 13 is cylindrical and is integrally formed with the shift block 30. A slide groove 14 is provided through the base 10. The end of the slide groove 14 close to the cover 15 is flared. When the shift block 30 is embedded and installed in the transverse groove 70, the protrusion 13 is just inserted into the slide groove 14 and can slide horizontally in the slide groove 14. Since the slide groove 14 runs through the base 10, the cover 15 can be opened and the protrusion 13 can be moved from the outside of the base 10 to drive the shift block 30 to slide horizontally left and right. When the shift block 30 moves toward the locking block 20, it will push the locking block 20 to overcome the elastic force of the coil spring, so that the locking block 20 can be embedded in the limiting groove 21, thereby limiting the rotation of the rotating shaft 11 and achieving the locking function. When the shift block 30 is completely moved to the end with the inclined surface 31 abutting against the end wall of the horizontal groove 70, the convex ridge 32 has been separated from the inclined surface 31, and one end of the locking block 20 is completely embedded in the limiting groove 21, and the end of the locking block 20 away from the rotating shaft 11 abuts against a side wall of the shift block 30, so that the locking block 20 is blocked and cannot slide, thereby ensuring the position stability of the locking block 20 in the locked state.

[0035] A first clamping block 40 is provided at the end of the lock block 20 away from the rotating shaft 11. The first clamping block 40 is located at the position of the convex ridge 32. The first clamping block 40 is formed integrally with the lock block 20. A second clamping block 41 is provided at a position of the side wall of the shift block 30 close to the lock block 20 and close to one end of the inclined surface 31. The second clamping block 41 is formed integrally with the shift block 30. When the convex ridge 32 is separated from the inclined surface 31, the shift block 30 can continue to slide until it contacts the end wall of the transverse groove 70. This process causes the side wall of the shift block 30 and the side surface of the lock block 20 away from the rotating shaft 11 to have a contact surface that contacts each other, and the first clamping block 40 and the second clamping block 41 squeeze each other and pass over each other. As a result, the lock block 20 and the shift block 30 are relatively snap-fitted and connected, and the shift block 30 is not easy to move relative to the lock block 20 to change the locked state, thereby improving the reliability of the locking.

[0036] In other embodiments, if the user does not need a double locking effect, the locking block and the shift block and their corresponding parts can be installed at only one end; or the transverse groove 70 and the longitudinal groove 71 are only set on one side of the base 10, and the locking block and the shift block and their corresponding parts are installed, and the transverse groove 70 and the longitudinal groove 71 and other structures are not set on the other side, thereby shortening the length of the base 10.

[0037] A boss 50 is installed at one end of the shift block 30 close to the locking block 20, and the boss 50 is integrally formed with the shift block 30. The boss 50 is located at a position close to the base 10 on the side of the inclined surface 31. A corner groove 51 is provided at one end of the locking block 20 away from the rotating shaft 11 and close to the convex ridge 32. The side of the boss 50 away from the shift block 30 and the corner groove 51 are both provided with guide surfaces 52, and the two guide surfaces 52 are parallel to the inclined surface 31. When the convex ridge 32 slides on the inclined surface 31, the guide surface 52 of the boss 50 and the guide surface 52 of the corner groove 51 slide in a matching manner. In this way, the relative sliding direction of the locking block 20 and the shift block 30 can be limited, and the stability of the relative sliding of the locking block 20 and the shift block 30 can be improved. When the ridge 32 is separated from the inclined surface 31 , the guide surface 52 of the boss 50 and the guide surface 52 of the notch groove 51 also begin to separate relatively, so that the other side of the boss 50 abuts against the end of the locking block 20 away from the shaft 11 , ensuring the stability of the locked state.

[0038] A positioning block 60 is installed at one end of the locking block 20 away from the rotating shaft 11, and a first positioning surface 61 is provided at one end of the positioning block 60 close to the shifting block 30, and the first positioning surface 61 is parallel to the inclined surface 31. When the locking block 20 is completely embedded in the limiting groove 21, that is, when the end of the shifting block 30 close to the inclined surface 31 contacts the end wall of the transverse groove 70, the first positioning surface 61 just coincides with and contacts the inclined surface 31. Thus, the locking block 20 and the shifting block 30 restrict each other, and the overall stability is improved.

[0039] The boss 50 is provided with a second positioning surface 62, which is perpendicular to the inclined surface 31. A third positioning surface 63 is formed on the side of the positioning block 60 close to the base 10, which is perpendicular to the first positioning surface 61, and the second positioning surface 62 is parallel to the third positioning surface 63. When the locking block 20 is inserted into the limiting groove 21, the second positioning surface 62 and the third positioning surface 63 are in contact and slide relative to each other, thereby further limiting the relative position of the locking block 20 and the shifting block 30 in the direction perpendicular to the second positioning surface 62, and further improving the overall stability.

[0040] Mounting blocks 18 are integrally formed at both ends of the base 10, and the mounting blocks 18 are square structures. One side of the mounting block 18 is fitted with one side of the base 10 to form an integral body, and a longitudinal groove 71 is formed between the second side of the mounting block 18 and the other side wall of the base 10; a transverse groove 70 is formed between the third side of the mounting block 18 and the end side of the base 10, and the fourth side of the mounting block 18 forms a partial side wall structure of the groove for the installation of the rotating shaft 11. Countersunk holes are provided through the mounting block 18, and the base 10 can be installed on the door and window structure by bolts passing through the countersunk holes, so as to facilitate the fixed installation of the base 10. A bottom plate 12 is installed on the side of the mounting block 18 away from the base 10 by riveting, and the bottom plate 12 covers the end of the base 10 away from the surface cover 15, and the locking block 20 and the shifting block 30 are both against the bottom wall of the base 10 on one side and against the bottom plate 12 on the other side. After the bottom plate 12 is installed, the bottom plate 12 and the base 10 can be clamped to fix the locking block 20 and the shifting block 30 , so that the locking block 20 and the shifting block 30 are relatively fixedly installed.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
