Description

Technical Field

[0001] This utility model relates to the field of electric push rods for window pushers, and specifically to a compact electric push rod for window pushers. Background Technology

[0002] The electric push rod of a window opener is a commonly used linear actuator, mainly used to realize the automatic opening and closing of windows. It also has a good self-locking function, which can fix the position of the window when it is pushed to a certain angle.

[0003] A search revealed that patent document CN214659582U discloses an electric push rod driven electric window opener. This electric push rod, through the interconnection of a support column, a buffer pad, a shock-absorbing spring, and a shock-absorbing chamber, reduces vibrations generated during operation. The buffer pad at the bottom of the push rod reduces vibrations generated by the electric push rod during operation. Simultaneously, the shock-absorbing chamber at the bottom of the buffer pad, with its internal shock-absorbing springs, effectively counteracts wind-induced vibrations during operation. The support column at the bottom of the shock-absorbing chamber provides stable support to the base, further reducing vibrations and improving the device's practicality.

[0004] The exposed design of the aforementioned electric actuator makes it easy for external dust to enter the actuator through the sliding gap, causing wear due to dust friction between the lead screw and the slider inside the actuator. However, since the actuator housing is fixed, the entire actuator needs to be removed from the window for disassembly and maintenance, which is difficult and cumbersome. Utility Model Content

[0005] In view of the problems existing in the compact electric push rod of the window pusher, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a compact electric push rod for window pushers, which solves the problem that when electric push rods need to be inspected after long-term operation, it is necessary to spend a lot of time disassembling the electric push rod and then disassembling the outer shell of the electric push rod, which is a rather cumbersome operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A compact electric push rod for a window opener includes an electric push rod body, which includes a first side block and a second side block symmetrically arranged on both sides. A steel outer shell is wrapped between the first side block and the second side block, and a lead screw and a moving tube are provided inside the steel outer shell.

[0009] A plurality of symmetrically arranged limiting rods are fixed between the first side block and the second side block. One side of the outer shell steel strip is fixed to the outside of the limiting rods, and the other side is provided with a positioning and wrapping mechanism between the first side block and the second side block.

[0010] Preferably, sealing blocks are fixedly sleeved on both outer ends of the plurality of limiting rods, and two sealing blocks are fixedly connected to the first side block and the second side block respectively on opposite sides, and the outer steel strip is fixedly disposed on the outside of the sealing blocks.

[0011] Preferably, the positioning and packaging mechanism includes two symmetrically arranged mounting plates, which are respectively fixedly connected to the side of the first side block and the second side block, and two symmetrically arranged insertion holes are opened inside the side end of the outer shell steel strip;

[0012] A rod is slidably inserted inside the mounting plate. The end of the rod is inserted into the insertion hole. A spring is sleeved on the rod wall. The two ends of the spring are fixedly connected to the rod and the mounting plate, respectively.

[0013] Preferably, both of the sockets are arranged in a strip shape.

[0014] Furthermore, a groove is provided on the side of the mounting plate away from the outer casing steel strip, and the spring is embedded in the groove.

[0015] Preferably, a pushing slope is provided on the outer side of one end of the two insertion rods near the outer steel strip of the outer casing.

[0016] Preferably, the ends of the two insertion rods away from the outer casing steel strip are jointly fixed with a pull rod, and the pull rod is bonded and fixed to the insertion rod.

[0017] Preferably, the tie rod is a U-shaped tie rod.

[0018] Preferably, a sealing strip is fixedly provided on the inner side of the end of the outer steel strip away from the limiting rod, and the sealing strip is in contact with the outer wall of the outer steel strip.

[0019] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0020] 1. This utility model, through the electric linear actuator body, first side block, second side block, outer shell steel strip, limiting rod and positioning wrapping mechanism, can transform the original integrated outer shell of the electric linear actuator into a detachable wrapping shell, which allows for quick maintenance of the internal components of the electric linear actuator without changing the position of the electric linear actuator, thus improving the compactness and usability of the electric linear actuator.

[0021] 2.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model discloses a compact electric push rod for a window pusher.

[0032] Example 1

[0033] This utility model provides, for example Figure 1-5 The electric push rod of the window pusher shown has a compact structure and includes an electric push rod body. The electric push rod body includes a first side block 1 and a second side block 2 symmetrically arranged on both sides. A steel outer shell 3 is wrapped between the first side block 1 and the second side block 2. A lead screw 4 and a moving tube 5 are provided inside the steel outer shell 3.

[0034] Multiple limiting rods 6 are fixedly arranged symmetrically at the four corners between the first side block 1 and the second side block 2, and one side of the outer shell steel strip 3 is fixedly located on the outside of the limiting rods 6.

[0035] When the electric push rod of the window opener is in use, the electric push rod is integrally formed by wrapping the outer shell steel strip 3 around the outside of the electric push rod body. When it is necessary to inspect the internal lead screw 4 and moving tube 5 of the electric push rod, the outer shell steel strip 3 can be opened to expose the internal components of the electric push rod body. At this time, the internal components of the electric push rod can be quickly inspected without changing the use position of the electric push rod, thus improving the use effect of the electric push rod.

[0036] Example 2

[0037] Example 2, based on Example 1, aims to determine the position of the outer casing steel strip 3 and to integrally form the electric actuator, such as... Figure 1-5 As shown, a positioning and wrapping mechanism is provided between the other side and the first side block 1 and the second side block 2. Both insertion holes 9 are arranged in the shape of strip holes. The positioning and wrapping mechanism includes two symmetrically arranged mounting plates 8. The two mounting plates 8 are fixedly connected to the side of the first side block 1 and the second side block 2 respectively. Two symmetrically arranged insertion holes 9 are opened inside the side end of the outer shell steel strip 3.

[0038] Insert rods 10 are slidably inserted inside the mounting plate 8. The ends of the insert rods 10 are inserted into the insertion holes 9. Pushing slopes 13 are provided on the outer side of the two insert rods 10 near the outer steel strip 3. Springs 11 are sleeved on the rod walls of the insert rods 10. The two ends of the springs 11 are fixedly connected to the insert rods 10 and the mounting plate 8 respectively. A groove 12 is provided on the side of the mounting plate 8 away from the outer steel strip 3. The springs 11 are embedded in the groove 12. A pull rod 14 is fixedly provided on the ends of the two insert rods 10 away from the outer steel strip 3. The pull rod 14 is bonded and fixed to the insert rods 10. The pull rod 14 is a U-shaped pull rod.

[0039] When the electric actuator needs to be disassembled, the pull rod 14 can be pulled to pull the two insert rods 10, causing the insert rods 10 to be pulled out of the insertion hole 9. At this time, the spring 11 is stretched, and then the outer steel strip 3 can be opened, so that the outer steel strip 3 is unfolded and set horizontally, exposing the internal components of the electric actuator, which is convenient for disassembly of the internal components of the electric actuator. After the internal components of the electric actuator are inspected and repaired, the outer steel strip 3 can be wrapped around the outside of the electric actuator. When the side of the outer steel strip 3 contacts the insert rod 10, the pushing slope 13 of the insert rod 10 is pushed, causing the insert rod 10 to move longitudinally. When the outer steel strip 3 is wrapped to a fixed position, the spring force of the spring 11 returns, the insert rod 10 springs back and inserts into the insertion hole 9, and the position of the outer steel strip 3 is fixed in one go, completing the overall forming of the electric actuator.

[0040] Example 3

[0041] Example 3, based on Examples 1-2, aims to ensure the sealing of the connection between the outer casing steel strip 3 and the electric push rod, such as... Figure 1-2 As shown, sealing blocks 7 are fixedly sleeved on both ends of the outer side of multiple limiting rods 6. The two sealing blocks 7 are fixedly connected to the first side block 1 and the second side block 2 respectively on the side away from each other. The outer steel strip 3 is fixedly installed on the outer side of the sealing blocks 7. A sealing strip 15 is fixedly installed on the inner side of the end of the outer steel strip 3 away from the limiting rods 6. The sealing strip 15 is in contact with the outer wall of the outer steel strip 3.

[0042] With the sealing connection of the sealing block 7, the first side block 1, and the second side block 2, the two ends of the outer casing steel strip 3 are well sealed when wrapped. At the same time, with the sealing strip 15 in sealing contact with the outer casing steel strip 3 itself, the sealing performance of the outer casing steel strip 3 when wrapped can be guaranteed, thereby improving the sealing effect of the electric push rod during the overall use process.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
