Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transmission technology, and specifically relates to a 90-degree transmission device. Background Technology
[0002] The transmission mechanism is mainly used to transmit the operating commands of the handle to the doors and windows, thereby realizing the opening and closing functions of the doors and windows.
[0003] The structure of the transmission device in the current technology is shown in this patent. CN203430228U discloses a push-pull transmission device for doors and windows, which includes a fixed plate, two wheel guards on the left and right, a sliding plate, an anti-pry pin and a gear as a whole. The fixed plate and the sliding plate are assembled in one wheel guard. The gear teeth are assembled on the rack of the sliding plate. The shaft of the gear end face is rotatably inserted into the rotating hole of the wheel guard. The other wheel guard is fastened to the assembled wheel guard. The shaft of the gear has a hole for installing a handle for operation. The anti-pry pin passes through the long sliding hole of the fixed plate and is riveted to the sliding plate. The anti-pry pin cooperates with the locking device on the door and window frame to lock or open the door and window.
[0004] One drawback is that, since the width and specifications of doors and windows vary greatly, the specifications of the actuator (such as the length specification) must be matched with the specifications of the doors and windows. That is, the lengths of the fixed plate and the sliding plate need to be matched with the dimensions of the doors and windows. Therefore, it is necessary to produce actuators of various specifications to meet the requirements, which increases production costs and is not convenient for production. Utility Model Content
[0005] This invention provides a 90-degree transmission device that can solve the problems pointed out in the background art.
[0006] A 90-degree transmission device includes a housing, a transmission housing fixed on the housing, and a sliding connecting plate. The sliding connecting plate reciprocates along the sliding limiting space formed by the housing and the transmission housing. Both ends of the sliding connecting plate have connecting ends for connecting a transmission rod. A transmission gear is rotatably connected inside the transmission housing. The sliding connecting plate has toothed holes at corresponding positions that mate with the transmission gear.
[0007] Preferably, the transmission housing includes two side housings, which are fixedly connected to form the transmission housing. The inner sides of the two side housings are respectively provided with corresponding limiting grooves, and the limiting grooves on both sides and the outer shell form the sliding limiting space.
[0008] Preferably, the outer shell is provided with side shell mounting grooves on both sides, and a plurality of positioning holes are provided in the side shell mounting grooves. The side shell is provided with positioning protrusions that limit and position the positioning holes. The side shell mounting grooves on both sides are fixedly connected by bolts after they are aligned.
[0009] Preferably, the connecting end is a rivet connecting end.
[0010] Beneficial effects: This utility model provides a 90-degree transmission device, which realizes a standardized structural design and forms a small standard part. It can meet the assembly requirements of different specifications of doors and windows by simply connecting transmission rods of different lengths according to the specifications of doors and windows. The transmission rods can be cut to the required length, which can greatly simplify the manufacturing process, improve assembly efficiency, and the transmission device has strong integrity, good applicability, low manufacturing cost, and saves materials. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the structure of this utility model.
[0012] Explanation of reference numerals in the attached figures:
[0013] The following are the labels in the diagram: outer shell 1; side shell mounting groove 11; positioning hole 12; transmission shell 2; transmission gear 21; side shell 22; limiting groove 23; positioning protrusion 24; sliding connecting plate 3; connecting end 31; toothed hole 32. Detailed Implementation
[0014] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0015] Example 1: As Figure 1 As shown in the figure, the 90-degree transmission device provided by this utility model embodiment includes a housing 1, a transmission housing 2 fixed on the housing 1, and a sliding connecting plate 3. The sliding connecting plate 3 slides back and forth along the sliding limiting space formed by the housing 1 and the transmission housing 2. The two ends of the sliding connecting plate 3 are respectively provided with connecting ends 31. The connecting ends 31 are used to connect the transmission rod. The connecting ends 31 are rivet connecting ends. The transmission gear 21 is rotatably connected inside the transmission housing 2. The sliding connecting plate 3 is provided with toothed holes 32 that cooperate with the transmission gear 21 at the corresponding positions.
[0016] Specifically, the transmission housing 2 includes two side housings 22. The two side housings 22 are joined and fixedly connected to form the transmission housing 2. The inner sides of the two side housings 22 are respectively provided with corresponding limiting grooves 23. The limiting grooves 23 on both sides form a sliding limiting space with the outer shell 1. The two sides of the outer shell 1 are respectively provided with side housing mounting grooves 11. The side housing mounting grooves 11 are provided with a plurality of positioning holes 12. The side housings 22 are respectively provided with positioning protrusions 24 that limit and position with the positioning holes 12. The two side housing mounting grooves 11 are joined and fixedly connected by bolts to achieve a stable connection between the transmission housing 2 and the outer shell 1.
[0017] The working principle of this utility model is as follows: This structural design can form a small standard part of the transmission device. By simply connecting transmission rods of different lengths at both ends according to the specifications of the doors and windows, the assembly requirements of doors and windows of different specifications can be met. The transmission rods can be cut to the required length, and the size can be adapted by connecting the corresponding length of the transmission rod through the rivet connection end.
