DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] The general idea of the technical solution provided by the present utility model is as follows:
[0026] Please refer to Figures 1 to 7 , the actuator with a locking function includes: an actuator housing 100, in which a first rack 200, a second rack 500 and a gear 300 are provided. The first rack 200 and the second rack 500 are meshed with the gear 300. Among them, a locking hole 210 is provided on the first rack 200, and a locking member 400 is rotatably connected in the actuator housing 100. A protruding portion 410 matching the locking hole 210 is provided on the locking member 400. The protruding portion 410 is used to rotate with the locking member 400 and then insert into or disengage from the locking hole 210.
[0027] Specifically, the actuator housing 100 is a housing for accommodating internal transmission components. The design of the actuator housing 100 ensures the stability of each component and the reliability of operation. The first rack 200 and the second rack 500 are respectively meshed with the gear 300 to achieve a transmission effect. The locking hole 210 is provided on the first rack 200 for cooperating with the locking member 400 to achieve a locking or unlocking function. The locking member 400 is rotatably connected in the actuator housing 100, and a protruding portion 410 is provided thereon for matching with the locking hole 210. The rotation of the locking member 400 makes the protruding portion 410 insert into or disengage from the locking hole 210, thereby achieving the locking or unlocking function of the first rack 200.
[0028] During actual use, the actuator housing 100 can be installed in a preset groove of a door or window profile. Since the first rack 200 and the second rack 500 are meshed with the gear 300, when the first rack 200 moves, the second rack 500 can be driven to move through the gear 300, thereby completing the transmission action. When locking is required, by rotating the locking member 400, the protruding portion 410 on the locking member 400 is inserted into the locking hole 210 on the first rack 200, thereby restricting the movement of the first rack 200 and completing the locking. When unlocking is required, by rotating the locking member 400 in the reverse direction, the protruding portion 410 on the locking member 400 disengages from the locking hole 210 on the first rack 200, so that the first rack 200 can move freely and complete the unlocking. In this application, through the rotational movement of the locking member 400, the action of restricting or releasing the restriction on the first rack 200 is completed, thereby achieving the locking function of the actuator itself, and no additional lock is required to lock the door or window, simplifying the system structure and reducing the cost.
[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0030] Please refer to Figure 1 , the transmission housing 100 includes a first housing 110 and a second housing 120. The first housing 110 and the second housing 120 are connected by screws 130. A cavity 140 is formed between the first housing 110 and the second housing 120. The cavity 140 is used to install the first rack 200, the second rack 500, the gear 300, and the locking member 400. The first housing 110 and the second housing 120 cooperate to form a complete transmission housing 100. The two housings are connected by screws 130 to ensure the firmness and integrity of the transmission housing 100. The screws 130 can connect the first housing 110 and the second housing 120 through the designed hole positions, making it a solid whole. The cavity 140 is formed by the space between the first housing 110 and the second housing 120, and is used to accommodate and install key components inside the transmission, such as the first rack 200, the second rack 500, the gear 300, and the locking member 400. The split housing design allows for convenient disassembly and repair.
[0031] Please refer to Figure 1 , the first rack 200 is provided with a sliding connection hole 220. A sliding groove 190 is provided on the side wall of the transmission housing 100. The position of the sliding connection hole 220 corresponds to the position of the sliding groove 190. Specifically, the sliding connection hole 220 is used to connect with the window and door handle. The window and door handle can pass through the sliding groove 190 through a sliding mechanism and then insert into the sliding connection hole. When the window and door handle drives the sliding mechanism to slide, the sliding mechanism drives the first rack 200 to slide. For example, the sliding mechanism can be a square shaft connected to the window and door handle. The design of the sliding connection hole 220 matches the shape of the square shaft, enabling the sliding mechanism to insert into the sliding connection hole 220 through the sliding groove 190. The function of the sliding groove 190 is to provide a guiding channel for the smooth sliding of the sliding mechanism. The position of the sliding connection hole 220 corresponds to the position of the sliding groove 190, which can ensure that the sliding mechanism is aligned and inserted into the sliding connection hole 220 through the sliding groove 190.
[0032] Please refer to Figure 1 and Figure 2, openings 150 are provided on both sides of the transmission housing 100, and the first rack 200 and the second rack 500 pass through the transmission housing 100 from the openings 150. There is one opening 150 on each side of the transmission housing 100, and these openings 150 allow the first rack 200 and the second rack 500 to extend from the inside of the transmission housing 100, so as to realize the interaction between the mechanical components inside the transmission housing 100 and the external environment.
[0033] Please refer to Figure 4 and Figure 7 , an elastic positioning member 420 is provided on the locking member 400, and a positioning hole 160 matching the elastic positioning member 420 is provided on the side wall of the transmission housing 100. When the elastic positioning member 420 follows the locking member 400 to rotate and moves to the positioning hole 160, it is elastically limited by the positioning hole 160. The elastic limit between the elastic positioning member 420 and the positioning hole 160 realizes the positioning of the locking member 400. The elastic positioning member 420 can be kept in the positioning hole 160 by elastic force, so as to keep the locking member 400 in the correct position on the transmission housing 100.
[0034] Please refer to Figure 6 , the elastic positioning member 420 includes a steel ball 421 and a spring 422. The locking member 400 is provided with a receiving hole 430 for receiving the steel ball 421 and the spring 422. The first end of the spring 422 extends into the receiving hole 430, and the steel ball 421 is connected to the second end of the spring 422. The first end and the second end of the spring 422 are opposite ends. Specifically, the steel ball 421 can elastically slide in the receiving hole 430 of the locking member 400 under the elastic action of the spring 422. When the locking member 400 rotates, the steel ball 421 will rotate along with the locking member 400. When the steel ball 421 moves to the position of the positioning hole 160, the spring 422 will expand, so as to push the steel ball 421 into the positioning hole 160 to realize the limit. When the locking member 400 is rotated forcefully again, the steel ball 421 will compress the spring 422 and then disengage from the positioning hole 160, thereby releasing the limit.
[0035] Further, the receiving hole 430 is a hollow through-hole, the spring 422 is disposed within the receiving hole 430, the steel balls 421 include a first steel ball 421a and a second steel ball 421b, and the first steel ball 421a and the second steel ball 421b are respectively connected to two ends of the spring 422. When the first steel ball 421a and the second steel ball 421b move along the axial direction of the spring 422, the spring 422 will be compressed or extended. Specifically, when the first steel ball 421a and the second steel ball 421b move to the position of the positioning hole 160, the spring 422 will extend, thereby pushing the first steel ball 421a and the second steel ball 421b into the positioning hole 160 to achieve limiting. When the locking member 400 is further rotated forcefully, the first steel ball 421a and the second steel ball 421b will compress the spring 422 and then disengage from the positioning hole 160, thereby releasing the limiting. This design of double-end connection of the steel balls 421 can improve the stability and accuracy of positioning, ensuring that the locking member 400 can be reliably fixed at a predetermined position.
[0036] Please refer to Figure 1 and Figure 5 , a hollow first connection hole 170 is provided on the side wall of the transmission housing 100, the locking member 400 is provided with a first connection column 440, and the first connection column 440 is rotatably connected within the first connection hole 170. A rotary connection hole 441 is provided on the first connection column 440. Specifically, the rotary connection hole 441 is used to support or connect other components, allowing other components to enter the rotary connection hole 441 and then twist the locking member 400, so that the locking member 400 rotates within the first connection hole 170.
[0037] Please refer to Figure 5 , positioning holes 160 are provided on both sides of the first connection hole 170 on the side wall of the transmission housing 100. Specifically, the elastic positioning member 420 provides a positioning force when the locking member 400 rotates, and can enter the positioning hole 160 on the rotation path of the locking member 400, thereby achieving limiting at a specific rotation angle. The design of providing positioning holes 160 on both sides of the first connection hole 170 is for precise cooperation with the elastic positioning member 420. When the locking member 400 rotates to two predetermined positions, the elastic positioning member 420 will enter the positioning hole 160, thereby locking or stabilizing the locking member 400 at these positions, thus achieving the limiting function of two specific positions of rotation. More specifically, when the locking member 400 rotates to a position, the elastic positioning member 420 will pop out and enter the nearby positioning hole 160 to fix the locking member 400 at this position. When rotating to another position, the elastic positioning member 420 will pop out and enter another positioning hole 160 to achieve fixation at the second position.
[0038] Please refer to Figure 1, a hollow gear connection hole 180 is provided on the side wall of the transmission housing 100, and the gear 300 is provided with a second connection column 310, and the second connection column 310 is rotatably connected to the gear connection hole 180. Specifically, the hollow gear connection hole 180 on the side wall of the transmission housing 100 allows the second connection column 310 of the gear 300 to rotate therein. Specifically, the second connection column 310 realizes the stable rotation of the gear 300 through the cooperation with the gear connection hole 180.
