Description

Technical Field

[0001] This utility model relates to the field of blister trays, and in particular to a retractable blister tray. Background Technology

[0002] Blister trays, as a type of loading tool manufactured through a thermoforming process, are widely used in logistics, warehousing, and product display due to their lightweight, durability, and cost-effectiveness. Blister trays are typically made by heating and softening plastic sheets, then shaping them in a mold through vacuum adsorption or compressed air blowing. They have advantages such as structural stability, strong load-bearing capacity, and ease of cleaning and maintenance.

[0003] However, despite the excellent performance of blister trays in many aspects, their inherent fixed size limits their flexibility and applicability. In practical applications, items of different sizes and shapes often require trays of different sizes for loading, while traditional blister trays often only offer one or a limited number of fixed sizes. This results in the tray space not being fully utilized when loading smaller items, leading to resource waste. On the other hand, when loading larger items, the tray size may be insufficient, leading to unstable loading or even damage to the items or the tray itself.

[0004] Therefore, it is necessary to provide a new retractable blister tray to solve the above-mentioned technical problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figure 1-4 A retractable blister tray includes: a tray body 1, a base 2, and a limiting mechanism 4. The tray body 1 is divided into a fixed section 101 and a movable section 102. A corrugated telescopic section 103 is fixed between the fixed section 101 and the movable section 102. The base 2 is installed at the bottom of the tray body 1 and is fixedly connected to the fixed section 101. An L-shaped pull-out plate 3 is slidably connected to one end of the base 2 and is fixedly connected to the movable section 102. A blocking cover 5 is fixedly connected to the top of the base 2. The limiting mechanism 4 is installed between the tray body 1 and the L-shaped pull-out plate 3. The bottom of the L-shaped pull-out plate 3 is provided with a grip groove 6, and the inner wall of the grip groove 6 is provided with anti-slip texture. The corrugated telescopic section 103 is composed of multiple wave-shaped structural units connected in sequence, and each wave-shaped structural unit has a certain elasticity, so that the pallet body 1 can be smoothly and steadily extended and retracted between the fixed section 101 and the moving section 102. The bottom of the base 2 is provided with an anti-slip pad to increase the stability of the pallet during use and prevent it from sliding or tipping over. The pallet body 1, the base 2, the L-shaped pull-out plate 3 and the barrier cover 5 can all be made of environmentally friendly and biodegradable materials to meet modern environmental protection requirements.

[0028] It should be noted that when the pallet needs to be extended, the user can pull the moving section 102 to unfold the wave-shaped structural units in the corrugated telescopic section 103 in sequence until the desired length is reached; similarly, when the pallet needs to be shortened, the user can compress the corrugated telescopic section 103 to fold the wave-shaped structural units in sequence, thereby reducing the length of the pallet.

[0029] Please see Figure 3-4 The limiting mechanism 4 includes: a groove 41, a spring 42, a connecting piece 43, a spherical locking block 44, and a locking groove 45. The bottom end of the fixed section 101 is provided with a groove 41. The inner wall of the groove 41 is fixedly connected to the spring 42. The inner wall of the groove 41 is slidably connected to the connecting piece 43. One side of the connecting piece 43 is fixedly connected to one end of the spring 42. The other side of the connecting piece 43 is fixedly connected to the spherical locking block 44. The L-shaped pull plate 3 is provided with locking grooves 45 at equal intervals at the bottom end of the fixed section 101. The spherical locking block 44 engages with the locking groove 45. The surface of the spherical locking block 44 is coated with a layer of wear-resistant material to improve the wear resistance and service life between the spherical locking block 44 and the locking groove 45.

[0030] It should be noted that when the tray is at a certain length, the spherical locking block 44 will spring into the corresponding slot 45 on the L-shaped pull-out plate 3 under the action of the spring 42, thereby locking the length of the tray. When the length needs to be adjusted, the user can press the spherical locking block 44 to disengage it from the slot 45 and then adjust the length. After the adjustment is completed, the spherical locking block 44 will spring into the new slot 45 again to lock the new length.

[0031] The working principle of the retractable blister tray provided by this utility model is as follows:

[0032] The retraction mechanism of the tray body:

[0033] The pallet body 1 consists of two parts: a fixed section 101 and a movable section 102, which are connected by a corrugated telescopic section 103. The corrugated telescopic section 103 is composed of multiple wave-shaped structural units connected in sequence, and each wave-shaped structural unit has a certain elasticity. This design allows the fixed section 101 and the movable section 102 to move relative to each other, thereby realizing the change of the pallet length.

[0034] When the pallet needs to be extended, the user can pull the moving section 102 to unfold the wave-shaped structural units in the corrugated telescopic section 103 in sequence until the desired length is reached; similarly, when the pallet needs to be shortened, the user can compress the corrugated telescopic section 103 to fold the wave-shaped structural units in sequence, thereby reducing the length of the pallet.

[0035] The function of the limit mechanism:

[0036] To ensure the stability of the pallet during extension or shortening, the present invention installs a limiting mechanism 4 between the pallet body 1 and the L-shaped pull-out plate 3; the limiting mechanism 4 includes a groove 41, a spring 42, a connecting piece 43, a spherical locking block 44, and a locking groove 45;

[0037] When the tray is at a certain length, the spherical locking block 44 will spring into the corresponding slot 45 on the L-shaped pull-out plate 3 under the action of the spring 42, thereby locking the length of the tray. When the length needs to be adjusted, the user can press the spherical locking block 44 to disengage it from the slot 45 and then adjust the length. After the adjustment is completed, the spherical locking block 44 will spring into the new slot 45 again to lock the new length.

[0038] The fit between the L-shaped pull-out panel and the base:

[0039] A base 2 is installed at the bottom of the tray body 1, and the base 2 is fixedly connected to the fixed section 101; at the same time, an L-shaped pull plate 3 is slidably connected to one end of the base 2, and one end of the L-shaped pull plate 3 is fixedly connected to the moving section 102; this design allows the moving section 102 to drive the L-shaped pull plate 3 to slide on the base 2 when it extends or shortens, thereby realizing the length adjustment.

[0040] To facilitate user operation, the bottom of the L-shaped pull-out plate 3 is also provided with a grip groove 6 and anti-slip texture to increase grip comfort and stability.

[0041] The functions of the barrier and anti-slip mat:

[0042] A blocking cover 5 is fixedly connected to the top of the base 2 to prevent items from slipping off the pallet during loading; at the same time, an anti-slip pad is also provided at the bottom of the base 2 to increase the stability of the pallet during use and prevent it from sliding or tipping over.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
