Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor tents, and particularly relates to a central lock with an anti-pinch mechanism and a tent thereof. Background Art

[0002] With the continuous improvement of people's lives, tents are used more and more frequently. Tents generally include a foldable tent frame and a tarpaulin. The tent frame is composed of a canopy frame and four or more supporting legs. The supporting legs are used to support the canopy frame, and a locking structure is also provided on the supporting legs. The tarpaulin covers the canopy frame for sunshade, rain protection or wind protection. One way to lock the tent is to use a center lock to connect and lock the top structure of the tent, such as a center lock disclosed in Chinese patent CN108026736B. When this center lock is locked, the operator needs to push the center bottom cap upward so that the center rod above can be inserted into the center bottom cap to achieve locking. However, there are some difficulties in actual use. For example, the center lock is usually located at the top of the tent and is at a high height. When the center bottom cap is pushed upward, it is easy for the center rod to fail to align and insert into the center bottom cap, resulting in injuries. Utility Model Content

DETAILED DESCRIPTION

[0021] The central lock with an anti-pinch mechanism and the tent thereof of the utility model will be further described below in conjunction with the accompanying drawings. Example 1

[0022] like Figure 1-Figure 3 The central lock with an anti-pinch mechanism shown in the figure comprises a central rod 1, an upper top plate 2 and a lower bottom plate 3. The upper end of the central rod 1 is inserted into the upper top plate 2, and the lower end is movably inserted into the lower bottom plate 3. The central rod 1 is rotatably sleeved with an anti-pinch member 4, and a limiting member 5 is provided on the central rod 1 to limit the anti-pinch member 4. The anti-pinch member 4 is movably provided between the lower end of the central rod 1 and the limiting member 5. The distance between the limiting member 5 and the lower end of the central rod 1 is smaller than the distance between the limiting member 5 and the upper end of the central rod 1.

[0023] The anti-clamping member 4 is a plastic multi-headed through member, including a sleeve 41 movably sleeved on the center pole 1 and a through pipe 42 extending radially outward from the sleeve 41 along the center pole 1. The inner diameter of the sleeve 41 is smaller than the outer diameter of the mushroom head 6. The through pipes 42 are evenly distributed along the circumferential direction of the center pole 1. The number of through pipes 42 is consistent with the number of top pole assemblies 8 matched with the upper top plate 2, and a groove 43 for the poles of the tent to be inserted is formed between two adjacent through pipes 42. A plurality of upper hinge seats 21 for connecting the poles of the tent are provided on the upper top plate 2, and each upper hinge seat 21 and the corresponding groove 43 are aligned with each other. A plurality of lower hinge seats 31 for connecting the poles of the tent are provided on the lower chassis 3, and each lower hinge seat 31 and the corresponding groove 43 are aligned with each other.

[0024] In this embodiment, the anti-pinch member 4 is a cross-shaped plastic member (ie, a plastic four-way member), including a sleeve 41 movably sleeved on the center rod 1 and four through pipes 42 extending radially outward from the sleeve 41 along the center rod 1 .

[0025] In addition, the center lock of the present application further includes a locking mechanism, which is used to lock the center rod 1 and the lower chassis 3 with each other. The locking mechanism has a locked state and an unlocked state. When the locking mechanism is in the locked state, the mushroom head 6 at the lower end of the center rod 1 is inserted into the lower chassis 3; when the locking mechanism is in the unlocked state, the lower chassis 3 is separated from the mushroom head 6 at the lower end of the center rod 1. The locking mechanism of the present application is common knowledge, and the specific structure is not limited, as long as the detachable connection between the center rod 1 and the lower chassis 3 can be achieved through the locking mechanism.

[0026] As can be seen from the figure, a mushroom head 6 is provided at the lower end of the center rod 1, and the anti-pinch member 4 is movably provided between the mushroom head 6 and the limiting member 5, and the distance between the limiting member 5 and the mushroom head 6 is smaller than the distance between the limiting member 5 and the upper end of the center rod 1. In this embodiment, the limiting member 5 is a limiting screw provided on the center rod 1, and has a simple structure.

[0027] It can be understood that when unlocked, the anti-pinch member 4 slides down to the upper end surface of the mushroom head 5 (that is, the lower end surface of the sleeve 41 is in contact with the upper end surface of the mushroom head 6); when locked, the anti-pinch member 4 is pushed upward to the limit member 5 through the lower chassis 3 until the anti-pinch member 4 abuts against the lower end surface of the limit member 5 (that is, the upper end surface of the sleeve 41 abuts against the lower end surface of the limit member 5), and the tent is fully unfolded and the locking mechanism is locked.

[0028] An anti-pinch member 4 (a rotatable plastic multi-headed member) and a limiting member 5 are provided on the central pole 1. Not only can the position of the anti-pinch member 4 be adjusted according to the position of the pole when folding the tent so that the pole is placed in the receiving groove 43 of the anti-pinch member 4 to avoid collision and wear between the poles and extend the service life of the tent; the movable height of the anti-pinch member 4 can also be limited to avoid the tent being opened too high, and when the central pole deviates and is not aligned with the lower chassis 3, the central pole 1 can be prevented from deviating too long and poking people. Example 2

[0029] like Figure 4-Figure 6 A tent shown includes upright posts 7, a top rod assembly 8, a side rod assembly 9, and a center lock arranged on the top rod assembly 8. The center lock is the center lock with an anti-pinch mechanism in Example 1; it includes at least three upright posts 7 and top rod assemblies 8 that are the same number and correspond to the upright posts 7. The upper ends of any two adjacent upright posts 7 are respectively connected with side rod assemblies 9. The plurality of top rod assemblies 8 are movably connected through the center lock in Example 1. Specifically in this embodiment, the number of upright posts 7 is four, and they are arranged at equal intervals to form a cubic space. The upright posts 7 generally extend in the vertical direction to support the tent on the ground. There are four top rod assemblies 8 correspondingly, which are used to form the top frame of the tent. There are also four side rod assemblies 9 correspondingly, which are respectively located around the front, back, left, and right sides of the tent.

[0030] Specifically, each column 7 is respectively provided with a slider 71 that can slide in the up and down directions, and the lower end of each push rod assembly 8 is rotatably connected to the corresponding slider 71. The specific structure of the column 7 and the push rod assembly 8 can adopt the structure known in the prior art, which can be seen in patent document CN212927306U and will not be repeated here.

[0031] The side bar assembly 9 is composed of one or more cross brace members 91 that are rotatably connected in sequence so as to be foldable and unfoldable, so that adjacent columns 7 can be brought closer to each other and unfolded. The side bar assembly 9 can adopt a structure known in the prior art, which can be seen in patent document CN107476647A, and will not be described in detail here.

[0032] 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.
