Detailed Description

In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clear, the utility model is further described below with reference to the accompanying drawings and embodiments.

Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

As shown in fig. 1 to 6, the utility model provides a screen window bolt, which comprises a positioning block 100, a spring member 200, a push rod 300 and a push key 400, wherein a containing groove 101 is arranged in the positioning block 100, a positioning groove 102 is arranged at the top of the positioning block 100, the positioning groove 102 is communicated with the containing groove 101, the spring member 200 is arranged in the containing groove 101, the push rod 300 comprises a positioning rod 301, a connecting section 302 and a pin 304, the connecting section 302 is connected with the positioning rod 301 and the pin 304, the positioning rod 301 is sleeved in the spring member 200, the connecting section 302 and the pin 304 extend out of the positioning block 100, the push key 400 is fixedly connected with the connecting section 302 through a connecting rod 500, the push key 400 is arranged above the containing groove 101, the connecting rod 500 is arranged in the positioning groove 102, a limiting piece 103 is arranged on the positioning block 100, and the limiting piece 103 is used for preventing the connecting rod 500 from being separated from the positioning groove 102.

The positioning block 100 is fixed at the edge angle of the screen window 600, the push key 400 is arranged outside the screen window 600, and the position of the pin 304 is driven to move by pushing the push key 400, so that the screen window 600 is locked and unlocked. Specifically, the spring member 200 is sleeved on the positioning rod 301, and the spring member 200 is firmly limited in the accommodating groove 101 through the cooperation of the connecting rod 500 and the limiting member 103, so that the spring member 200 cannot escape from the accommodating groove 101. When the pushing key 400 is not applied with force, the spring is in a normal state, the pins 304 and part of the connecting section 302 extend out of the accommodating groove 101, pin holes are formed in the screen window frame, the pins 304 are inserted into the screen window frame through the pin holes, and the screen window 600 is locked at the moment; the pushing key 400 is forced, that is, the pushing key 400 is pushed, the pushing key 400 drives part of the connecting section 302 to enter the accommodating groove 101, the spring member 200 is compressed, the pins 304 retract inward toward the screen window 600 and retract into the screen window 600 integrally, at this time, the screen window 600 loses connection with the screen window frame, and the screen window 600 is unlocked. The connecting rod 500 can only slide along the direction of the positioning groove 102, and the sliding distance is determined by the length of the positioning groove 102, so that the accurate extension and retraction of the pins 304 can be realized as long as the length of the positioning groove 102 is controlled, the opening and closing of the pins can be realized only by controlling the sliding of the push key 400, the convenience of the pins of the screen window 600 is stronger, the operation is simple, and meanwhile, the push key 400 and the push rod 300 are integrally designed, the connection is reliable, and the performance is stable.

Further, one end of the spring member 200 contacts the wall of the accommodating groove 101, the other end is sleeved on the positioning rod 301, and the diameter of the connecting section 302 at the joint with the positioning rod 301 is larger than that of the spring member 200, so that the spring member 200 is firmly fixed between the connecting section 302 and the inner wall of the accommodating groove 101, and the spring member 200 is sleeved on the positioning rod 301, so that the spring member 200 can only be compressively deformed along one direction, and the effective retractility of the pins 304 is ensured.

Further, the diameter of the connecting section 302 at the connection with the pin 304 is greater than the diameter of the pin 304. In a specific operation, since the width of the screen window frame is limited, the length of the pin 304 extending out of the screen window 600 is not too long, and therefore, when the screen window 600 is locked, the connecting section 302 connected with the pin 304 should remain in the screen window 600, therefore, the size of the pin hole formed in the screen window 600 can only enable the pin 304 to pass through, the diameter of the connecting section 302 is larger than that of the pin 304, and the connecting section 302 can remain in the screen window 600 completely, so as to ensure the practicability of the pin.

Further, a first guide groove 104 is formed in the bottom of the positioning block 100, a sliding block 303 is fixed to the bottom end of the connecting section 302, and the sliding block 303 is arranged in the first guide groove 104. When the push button 400 slides, the slider 303 moves along the first guide groove 104, so as to further reduce the shake of the push rod 300 during movement.

Further, a second guiding groove 401 is formed at one end of the bottom of the push button 400, one end of the top of the positioning block 100 is disposed on the protruding block 105, and the protruding block 105 is disposed in the second guiding groove 401. When the push button 400 slides, the protrusion 105 moves along the second guide groove 401, reducing the shake of the push button 400 during movement.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
