Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a handle with a locking function. Background Art

[0002] With the continuous development of modern architecture, the appearance of buildings is becoming more and more complex. Therefore, glass curtain walls that can be applied to complex appearances are being adopted by more and more buildings. In addition, modular curtain wall systems make the construction process more efficient and lighter, and the entire building is neater and more beautiful in appearance. Curtain wall windows are the most important ventilation channels in the curtain wall system and are of vital importance. Of course, due to the need to open and close frequently, they are also the most problematic components in the curtain wall system. For example, it is necessary to ensure that the window sash does not fall off when it is opened, to avoid the window sash swinging back and forth in harsh environments, and to ensure good air tightness and water tightness when the window sash is closed. The window sash is closed by turning the handle to drive the connecting rod and the locking point connected to the connecting rod to cooperate with the lock seat to complete the locking. However, in windy and rainy weather, curtain wall windows on high floors will face a common problem. That is, after the window sash is closed, the window sash will vibrate continuously due to the difference in wind pressure between the inside and outside. Although this slight but frequent vibration will not cause the lock seat to break, it will cause the locking point to slowly fall out of the lock seat, thereby placing the entire window sash in an open state. At this time, in a windy environment, the window sash will be completely out of control and there is a risk of falling off. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] See also Figure 1-Figure 8, are schematic diagrams of the structure of the handle with locking function of the utility model and its components.

[0026] As shown in the figure, the handle with locking function provided by the embodiment of the utility model has an overall structure including a handle 1, a handle seat 2, a locking mechanism 3, a transmission member 4 which links the handle 1 and the locking mechanism 3, and a limiting mechanism 5 for limiting the transmission member 4. The locking mechanism 3, the transmission member 4 and the limiting mechanism 5 are respectively arranged in corresponding installation grooves in the handle seat 2. The transmission member 4 is axially connected to the handle 1, and the other end of the transmission member 4 is linked to the locking mechanism 3. When the handle 1 rotates, the transmission member 4 is driven to rotate, so as to link the locking mechanism 3 to lock or unlock the window frame and the window sash. The limiting mechanism 5 achieves limitation by squeezing the transmission member 4 to limit the rotation of the transmission member 4.

[0027] The locking mechanism 3 includes an elastic member 31 , a bracket 32 ​​and a fork 33 . The elastic member 31 is installed in the bracket 32 ​​and one end of the elastic member 31 abuts against the inner wall of the bracket 32 ​​, and the other end extends from the through hole of the bracket 32 ​​to abut against the transmission member 4 passing through the bracket 32 ​​.

[0028] Further, as a specific implementation, the elastic member 31 includes a steel ball 311 and a spring 312 , the steel ball 311 is connected to the spring 312 , the spring 312 abuts against the inner wall of the bracket 32 ​​, and the steel ball 311 abuts against the transmission member 4 .

[0029] By rotating the handle, the transmission member is driven to rotate, thereby causing the fork to reciprocate to achieve locking or unlocking.

[0030] The utility model uses a limiting mechanism to squeeze and limit the transmission member in the handle locking state to limit the rotation of the transmission member. At this time, the entire transmission system is in a locked state, and the handle cannot be rotated, which can effectively prevent the pull fork from sliding out of the lock seat when the window is locked. Moreover, when the handle is in an unlocked state, the handle can rotate freely and normally, and rotating the handle can drive the transmission member to rotate, thereby driving the locking mechanism to lock or unlock. When the window sash is opened, the transmission member can also be limited by the limiting mechanism to lock the handle, thereby preventing people who are not familiar with the closing operation from rotating the handle to the handle closing position during the window sash closing process. At this time, when the window sash is closed, the pull fork will directly hit the lock seat, and the strong impact is likely to damage the pull fork and the lock seat. When the pull fork is locked in the open position, the lock seat will be staggered to avoid the above-mentioned abnormal situation.

[0031] Among them, as a specific implementation method, the limiting mechanism 5 includes a sliding limit block 51, a first positioning block 52 and a second positioning block 53. The sliding limit block 51 is set in the slot of the handle seat 2 and can slide horizontally along the slot. The inner sides of the first positioning block 52 and the second positioning block 53 are pressed into springs and limited in the two notches 511 of the sliding limit block 51. The outer sides of the first positioning block 52 and the second positioning block 53 abut against the inner wall of the handle seat 2. The handle seat 2 is provided with a positioning groove 21 for the first positioning block 52 and the second positioning block 53 to pop out.

[0032] After the handle is assembled, the handle can be rotated freely, and rotating the handle can drive the transmission member to rotate, thereby driving the fork to reciprocate. Regardless of whether the handle is in the open position or the closed position, when the sliding limit block slides to the bottom and the second positioning block is inserted into the positioning groove, the sliding limit block does not enter the gap between the transmission member and the handle seat at this time, so the transmission member cannot be limited. As long as the handle is rotated, the transmission member can be driven to rotate. When the second positioning block is pressed and the second positioning block is moved to drive the sliding limit block to slide back horizontally along the slot, the front end of the sliding limit block gradually enters the gap between the transmission member and the handle seat, thereby squeezing and rubbing the transmission member to limit the rotation of the transmission member until the first positioning block is exposed and inserted into the positioning groove. At this time, the sliding limit block is positioned in the gap between the transmission member and the handle seat, completely limiting the rotation of the transmission member, and the handle will not be able to rotate at this time.

[0033] (See Figure 3 , Figure 4 )

[0034] As a specific implementation method, the transmission member 4 is a gear shaft, the bottom end of the gear shaft has a plurality of gear teeth 41, and the shift fork has a rolling tooth 331 that matches the gear teeth.

[0035] As a specific implementation method, a plurality of gears 4 are further provided on the upper end surface of the gear shaft, and the plurality of gears and the bracket mesh with each other.

[0036] As a specific implementation method, the handle with a locking function further includes a bottom cover 6 , on which a fixing seat 7 is provided, which is fixed in cooperation with the column hole of the handle seat 2 .

[0037] In the utility model, the handle base and the bottom cover are assembled together, and the interior thereof is a hollow cavity, and the locking mechanism, the limiting mechanism and the transmission member are all arranged in the cavity. In addition, the handle base and the bottom cover are assembled by the column hole and the fixing base, and can be assembled and disassembled without additional tools.

[0038] The handle 1 is connected to the transmission member 4 via a screw 8 , so that the handle 1 and the transmission member 4 are assembled into one body, so that the rotation of the handle 1 drives the transmission member 4 to rotate.

[0039] Among them, a washer 9 is also arranged between the handle 1 and the handle seat 2. Through the arrangement of the washer, the handle can be prevented from being damaged by direct friction with the handle seat during repeated rotation, thereby extending the service life of the product.

[0040] Based on the handle structure design with locking function of the utility model, the specific assembly steps of the handle are as follows: install two steel balls and two springs into the bracket together, and then put them into the slot of the handle seat, install the two springs into the first positioning block and the second positioning block respectively, and then compress the springs and put them into the two notches of the sliding limit block, and then put them into the slot of the handle seat and slide to the bottom, so that the second positioning block pops out from the positioning slot of the handle seat, and then install the gear shaft, washer and handle, and connect them to the handle after passing the screws through the gear shaft and the washer, and finally assemble the fork and the bottom cover.

[0041] Based on the above detailed description of the handle with locking function in combination with the drawings in the specification, it can be understood that the locking function of the transmission member is combined with the handle to realize the opening, locking and locking functions of the handle without the need to install an additional locking mechanism.

[0042] With the handle with locking function of the utility model, the handle cannot be rotated when the handle is locked, because it is connected to the transmission system of the entire window, so the transmission system is also locked, thereby preventing the fork from sliding out of the lock seat when the window is locked. When the handle is in the unlocked state, the handle can be rotated normally. However, even if the handle is in the open state, the handle can be locked to prevent people who are not familiar with the closing operation from turning the handle to the closed position during the closing process in bed. At this time, when closing the window sash, the fork will directly hit the lock seat, and the strong impact may damage the fork and the lock seat. If the handle is locked, the above abnormal situation can be avoided.

[0043] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
