[0002] In the fields of laboratories, medicine, and biopharmaceuticals, test chambers are an important experimental device widely used in experiments such as bacterial culture, cell culture, and tissue culture. With the advancement of technology, the functional requirements for test chambers are increasing, especially in terms of ease of operation, safety, and aesthetics.

[0003] Traditional test chamber handles are mostly made of solid injection molding. While this design meets basic functional requirements to some extent, it also has some significant limitations: the solid structure leads to the use of a large amount of plastic material, increasing production costs and not conforming to current environmental protection trends; and because the solid structure requires more material and a more complex injection molding process, the manufacturing cost is higher.

[0004] Current technology often reduces the amount of injection molding to reduce weight or cost, resulting in a partially hollowed-out appearance in the handle. This not only affects the aesthetics but also makes it uncomfortable to hold and may even affect the stability of operation. Utility Model Content

[0005] To address the issues of high production costs and uncomfortable grip of traditional handles in existing technologies, this utility model provides a door handle for a test chamber.

[0006] The technical solution for a test chamber door handle provided by this utility model is as follows:

[0007] A door handle for a test chamber includes a main body and a rear cover. The main body is a hollow box-shaped structure with an opening on its outer surface. The rear cover is detachably connected to the main body and forms a sealed cavity with the opening. Several reinforcing ribs are integrally injection molded inside the main body, and the reinforcing ribs extend and distribute along the longitudinal or transverse direction of the main body.

[0008] Furthermore, the inner wall of the sealed cavity is provided with at least one set of snap-fit ​​grooves, and the edge of the rear cover is provided with snap-fit ​​posts corresponding to the snap-fit ​​grooves. The rear cover is fixed by the snap-fit ​​posts cooperating with the snap-fit ​​grooves.

[0009] Furthermore, the reinforcing ribs include longitudinal main ribs and transverse auxiliary ribs. The longitudinal main ribs extend along the length of the main body and there are 2-4 of them. The transverse auxiliary ribs are vertically connected between adjacent longitudinal main ribs to form a grid-like support structure.

[0010] Furthermore, both the main body and the back cover are made of polycarbonate or nylon composite materials, and the outer surface of the main body is provided with anti-slip ripples, the depth of which is 0.5mm-1.5mm.

[0011] Furthermore, a sealing strip is provided at the junction of the back cover and the opening. The sealing strip is made of silicone material and is integrally formed with the back cover through an embedded injection molding process.

[0012] Furthermore, the back cover is made of a transparent or semi-transparent material, and a detachable label is provided on the inside of the back cover. The label is fixed by magnetic attraction or plug-in method.

[0013] Furthermore, a connecting base is rotatably connected to the bottom of the main body. The connecting base is fixedly connected to the test chamber door by bolts, and a locking rod for unlocking the test chamber door is installed inside the connecting base.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] This utility model successfully solves a number of technical problems existing in traditional handles by combining a hollow box-shaped structure and a detachable back cover. First, the main body adopts a hollow design, which saves materials and reduces weight, while maintaining the integrity of the external shape and not affecting the aesthetics and grip.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described in detail below:

[0025] This utility model discloses a door handle for a test chamber, such as... Figure 1 , 3 As shown, a test chamber door handle includes a main body 1 and a rear cover 2. The main body 1 is a hollow box-shaped structure with an opening 11 on its outer surface. The rear cover 2 is detachably connected to the main body 1 and forms a sealed cavity with the opening 11. Several reinforcing ribs 3 are integrally injection molded inside the main body 1, extending or distributing along the longitudinal or transverse direction of the main body 1. In this embodiment, the design abandons the traditional solid injection molding method and adopts a hollow box-shaped structure design. The interior of the main body 1 is hollow, while the exterior maintains a complete box shape. The opening 11 is located on the outer surface of the main body 1, facilitating the subsequent installation of the rear cover 2. The hollow structure significantly reduces the amount of material used compared to the solid structure, thereby reducing production costs. It also reduces the overall weight of the handle 1, making operation easier. Although the interior is hollow, the exterior shape is complete, maintaining aesthetics and grip. The design of the reinforcing ribs 3 significantly improves the structural strength of the main body 1, making it more durable. Moreover, the reinforcing ribs 3 are built into the interior of the main body 1, without compromising the neat and aesthetically pleasing exterior.

[0026] like Figure 3 , 4 As shown, the inner wall of the sealed cavity is provided with at least one set of snap-fit ​​grooves 12, and the edge of the rear cover 2 is provided with snap-fit ​​posts 21 corresponding to the snap-fit ​​grooves 12. The rear cover 2 is fixed by the snap-fit ​​posts 21 cooperating with the snap-fit ​​grooves 12. In this embodiment, the edge of the rear cover 2 is designed with snap-fit ​​posts 21 or other connecting structures that match the snap-fit ​​grooves 12 or corresponding structures at the opening 11 of the main body 1. When the rear cover 2 is installed in place, the snap-fit ​​posts 21 will snap into the snap-fit ​​grooves 12 to achieve fixation. The detachable design allows users to easily remove the rear cover 2 for internal cleaning or maintenance. The rear cover 2 is tightly connected to the main body 1 to form a sealed cavity, preventing dust, moisture, etc. from entering the interior.

[0027] like Figure 3As shown, the reinforcing rib 3 includes longitudinal main ribs 31 and transverse auxiliary ribs 32. The longitudinal main ribs 31 extend along the length of the main body 1, and there are 2-4 of them. The transverse auxiliary ribs 32 are vertically connected between adjacent longitudinal main ribs 31 to form a grid-like support structure. In this embodiment, the longitudinal main ribs 31 extend along the length of the main body 1, and the number is controlled between 2-4 to provide the main structural support. The transverse auxiliary ribs 32 are vertically connected between adjacent longitudinal main ribs 31 to form a grid-like support structure. The grid-like support structure allows the main body 1 to distribute stress more evenly when under load, avoiding local overload. The cooperation between the longitudinal main ribs 31 and the transverse auxiliary ribs 32 significantly improves the overall stability of the main body 1.

[0028] like Figure 1-6 As shown, both the main body 1 and the back cover 2 are made of polycarbonate or nylon composite materials, and the outer surface of the main body 1 is provided with anti-slip ripples 13, the depth of which is 0.5mm-1.5mm. In this embodiment, polycarbonate and nylon composite materials have excellent physical properties, chemical stability and processing performance, making them suitable for manufacturing parts such as handles. The anti-slip ripples 13 are formed during injection molding on the outer surface of the main body 1, with the ripple depth controlled between 0.5mm and 1.5mm to increase friction when gripping. This helps prevent users from slipping while gripping, improves operational safety, and increases grip comfort and stability.

[0029] like Figure 4 As shown, a sealing strip 22 is provided at the joint between the back cover 2 and the opening 11. The sealing strip 22 is made of silicone and is integrally formed with the back cover 2 through an embedded injection molding process. In this embodiment, the silicone sealing strip 22 has good elasticity and sealing performance, effectively preventing external media from entering. The silicone material has good wear resistance and anti-aging properties, which extends the service life of the sealing strip 22.

[0030] like Figure 5 As shown, the back cover 2 is made of transparent or semi-transparent material, and a detachable label 23 is provided on the inner side of the back cover 2. The label 23 is fixed by magnetic attraction or plug-in method. The above is the second embodiment of the back cover 2 in this utility model. First, the user can observe the internal structure and status without disassembling the back cover 2, which is convenient for daily inspection and maintenance. The transparent or semi-transparent material increases the fashion and technological feel of the handle 1. The back cover 2 has a structure for installing the label 23, which is fixed by magnetic attraction or plug-in method, which is convenient for the user to replace or add label information as needed. The relevant information marked on the label 23 makes it easy for the user to quickly identify and operate.

[0031] like Figure 6 As shown, a connecting base 15 is rotatably connected to the bottom of the main body 1. The connecting base 15 is fixedly connected to the test chamber door by bolts, and a locking rod 151 for unlocking the test chamber door is installed inside the connecting base 15.
