Description

Technical Field

[0001] The utility model relates to a telescopic structure for a battery pack carrier, and belongs to the technical field of logistics carriers. Background Art

[0002] Carrier racks are widely used to fix battery packs during transportation. Existing carrier racks are mostly fixed in size. Due to the diversification of battery packs, the number of carrier racks that need to be compatible with them has also increased accordingly. That is, one specification of carrier rack corresponds to one specification of battery pack, which is more difficult to transport and replace, and the cost is high. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the purpose of the utility model is to provide a telescopic structure for a battery pack loading rack, in which the inner tube is plugged into the outer tube and is inserted into the circular hole, the connecting hole and the threaded ring in sequence by screws. When telescopic or extension is required, the relative position between the inner tube and the outer tube is changed and the tube is tightened and fixed by screws to achieve the purpose of adjustable size to accommodate battery packs of different sizes.

[0004] The technical solution adopted by the utility model is a telescopic structure for a battery pack loading rack, comprising an outer tube and inner tubes symmetrically plugged into two sides of the outer tube, and the outer tube and the inner tube are detachably connected.

[0005] Furthermore, the outer tube has a plurality of connecting holes at both ends, the connecting holes have threaded rings in them, and the inner tube has a row of a plurality of circular holes, and when the circular holes, the connecting holes and the threaded rings are aligned, they are tightened and fixed by screws.

[0006] Furthermore, a slide groove is provided on the side wall of the inner tube, and a U-shaped sliding member is provided in the slide groove.

[0007] Furthermore, a clamping groove which is in the same straight line as the slide groove is provided on the side wall of the end of the outer tube, and when the U-shaped sliding member moves to the clamping groove along with the inner tube, the U-shaped sliding member is clamped with the clamping groove.

[0008] The utility model discloses a telescopic structure for a battery pack carrier, which has the beneficial effect that, compared with the prior art, the outer tube and the inner tube are plugged in and matched to achieve size adjustment; when adjusting the size, it is only necessary to loosen or tighten the screws, and the operation is convenient and simple; the inner tube is pressed by the screws to prevent a small angle tilt caused by the inner tube extending too long when the carrier is forked.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] In order to further understand the content of the utility model, this technical solution is further explained below in conjunction with specific implementation methods.

[0018] Embodiment 1:

[0019] like Figures 1 to 5As shown, this embodiment provides a telescopic structure for a battery pack loading rack, including an outer tube 3 and inner tubes 2 symmetrically inserted on both sides of the outer tube 3, the outer tube 3 and the inner tube 2 are detachably connected, specifically, the side wall of the inner tube 2 is provided with a slide groove 22, and the slide groove 22 is provided with a U-shaped sliding member 23; the side wall of the end of the outer tube 3 is provided with a clamping groove 33 in the same line as the slide groove 22, when the U-shaped sliding member 23 moves to the clamping groove 33 with the inner tube 2, the U-shaped sliding member 23 is clamped with the clamping groove 33; the top of each end of the outer tube 3 is provided with 4 There are connection holes 30, each of which is evenly spaced, with a specific spacing of 50mm. A threaded ring 31 that cooperates with a screw 32 is welded inside the connection hole 30. The bottom of the threaded ring 31 is flush with the upper surface of the inner wall of the outer tube 3. The inner tube 2 has a row of several circular holes 21 with a spacing of 50mm. When the circular holes 21 and the threaded ring 31 are aligned, they are tightened and fixed by screws 32, and the outer wall of the bottom of the inner tube 2 is tightly attached to the inner wall of the bottom of the outer tube 3. The screw 32 passes through the threaded ring 31 and then embeds into the circular hole 21 of the inner tube 2 for fixing. Plug-in installation can be achieved by ensuring that the spacing between the circular hole 21 and the connection hole 30 is equal, and the spacing can be adjusted according to the size of the battery pack, such as 30mm, 40mm, 60mm, etc.

[0020] In actual application, the other end of the inner tube 2 is connected to the angle support 1 by bolts. When telescopic movement is required, the screw 32 is unscrewed so that the screw 32 leaves the circular hole 21 of the inner tube 2. At this time, the movement of the inner tube 2 is not restricted. When the inner tube 2 moves to the desired position, the screw 32 is tightened so that the screw 32 enters the circular hole 21 of the inner tube 2. At this time, the inner tube 2 and the outer tube 3 are fixed and the movement of the inner tube 2 is restricted. Specifically, when the inner tube 2 moves toward the outer tube 3, the U-shaped sliding member 23 will move with the inner tube 2 to enter the slide groove 22 of the outer tube 3 until it reaches the minimum size state, such as Figure 4 shown.

[0021] The screws 32 can be placed in any two of the threaded rings 31 where the four connection holes 30 are located. The position is adjustable and the applicability is higher. However, the screws 32 are usually inserted in the outermost connection holes 30, at which time the spacing is the largest and the inner tube 2 will be fixed more securely.

[0022] In this embodiment, the inner tube 2 is compressed by screws 32, that is, the inner tube 2 is limited, so that the bottom outer wall of the inner tube 2 can always be close to the inner wall of the outer tube 3, so that the contact surface on the carrier is always in the same horizontal plane regardless of fork lifting or transportation, which can ensure that the contact surface between the carrier and the items is horizontal and located on the same horizontal plane. If the inner tube 2 is fixed at other positions, when the inner tube 2 is pulled outward to a larger step diameter, the step diameter is 50mm, and during the fork lifting of the rack, the inner tube 2 itself is long, and there is a gap between the inner tube 2 and the outer tube 3, which may cause the utility model to tilt at a small angle, that is, the inner tube 2 also tilts at a small angle, then the upper plane of the carrier will not be on the same horizontal plane, and the items will also be at risk of tipping over.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
