Technical Field

[0001] This utility model relates to the field of injection molding technology for housings, specifically to an injection molding housing for a blood pressure monitor. Background Technology

[0002] Injection-molded housings are plastic housing products manufactured through injection molding processes. They are widely used in electronic equipment, home appliances, automotive parts, medical devices, and other fields. Blood pressure monitor housings are typically injection-molded. According to patent authorization announcement number CN216294031U, a blood pressure monitor housing injection-molded part is disclosed. This utility model discloses a blood pressure monitor housing injection-molded part, including a housing assembly and an installation mechanism and a grinding mechanism disposed on the housing assembly. When closing the upper and lower housings, simply pull the bolts to insert the first locking posts at the four corners of the upper housing into the second locking posts at the four corners of the lower housing, and then insert one side of the bolts into the slots on the first and second locking posts to fix the upper and lower housings. When disassembling the upper and lower housings, simply pull the bolts to release the fixation of the upper and lower housings, and lift the upper housing upwards. This facilitates the assembly and disassembly of the blood pressure monitor housing injection-molded part.

[0003] However, existing injection-molded housings require multiple disassembly mechanisms to be installed on the outside during use, resulting in poor housing integrity. These mechanisms are easily bumped and damaged during use, affecting normal operation and compromising the housing's seal. Furthermore, the support legs under the base plate are fixed inside, making disassembly and maintenance difficult after the anti-slip pads wear down. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a blood pressure monitor housing injection molded part, which solves the problems of poor overall integrity of the outer side of the housing and inconvenience in replacing the anti-slip pad.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The lower end of the support leg 4 is attached with an anti-slip pad 5. The support leg 4 is slidably connected to the connecting cover 6. The anti-slip pad 5 is made of silicone material. The snap-fit ​​bracket 9 located above the connecting seat 8 is snapped with the upper cover 2. The snap-fit ​​bracket 9 located below the connecting seat 8 is snapped with the connecting frame 11. The sealing frame 12 and the sealing frame 2 13 are both fixedly connected to the outer shell 1. The sealing frame 12 and the sealing frame 2 13 can improve the sealing performance of the outer shell 1. One end of the tension spring 10 is fixedly connected to the snap-fit ​​bracket 9, and the other end of the tension spring 10 is fixedly connected to the outer shell 1. The tension spring 10 can automatically reset the snap-fit ​​bracket 9 through its elastic force.

[0025] Please see Figure 3 , Figure 5 , Figure 6 The connecting mechanism 7 includes a fixed plate 71. Multiple pairs of evenly distributed fixed plates 71 are fixedly connected inside the base plate 3. Connecting pins 72 are slidably connected inside the fixed plate 71. Round head seats 73 are fixedly connected to the outside of the connecting pins 72. Guide bars 74 are fixedly connected inside the base plate 3. Springs 75 are provided on the outside of the connecting pins 72. An annular groove 76 is opened on the outer side of the upper end of the support leg 4. The round head seat 73 is slidably connected to the connecting cover 6. The guide bar 74 can guide the movement of the round head seat 73. The round head seat 73 is engaged with the annular groove 76. The round head seat 73 is slidably connected to the guide bar 74. The guide bar 74 is fixedly connected to the fixed plate 71.

[0026] The specific implementation process of this utility model is as follows: When in use, the upper cover 2 is slid into the interior of the outer shell 1. During the sliding process, the upper cover 2 pushes the snap-fit ​​bracket 9 to deflect. During the deflection process, the snap-fit ​​bracket 9 stretches the tension spring 10. When the snap-fit ​​bracket 9 contacts the hole of the upper cover 2, the tension spring 10 returns to its original position. The tension spring 10 can use its elasticity to drive the snap-fit ​​bracket 9 to snap into the interior of the upper cover 2, thus completing the limiting of the upper cover 2. Similarly, the base plate 3 is installed on the outside of the outer shell 1, thus completing the assembly of the blood pressure monitor shell, which can improve the overall integrity of the blood pressure monitor shell.

[0027] When the support leg 4 needs to be replaced, pull the support leg 4. During the movement, the support leg 4 pushes the round head seat 73 to move through the arc surface of the round head seat 73 and compresses the spring 75. When the round head seat 73 disengages from the annular groove 76, the restriction on the support leg 4 can be released, so that the support leg 4 can be easily removed for replacement. Then, insert the new support leg 4 into the inside of the connecting cover 6. During the insertion process, the support leg 4 pushes the round head seat 73 to move and compresses the spring 75. When the round head seat 73 is disengaged from the annular groove 76, the spring 75 returns to its original position. The spring 75 can use its elasticity to drive the round head seat 73 to slide into the inside of the annular groove 76, thus completing the replacement of the support leg 4 and the anti-slip pad 5.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
