The present invention opens a locking device. By virtue of the forward action it inserts the locking component 128 to the locking device 107a on the side of the holding part 109 so as to prevent the drawing of the storing box 111; by virtue of the back action it deviate the locking component 128 from the locking part 107a to allow the drawing out the storing box 111. Using the plate spring 129 set between the locking component 128 and the main body 113, it pushes the locking part 128 in the direction of inserting the locking part 107a. When it reaches the time that the holding part 109 is drawing out of the storing box 111, pull out the main body of the action bar which is supported by the axis and rotate at the outside of the box bulk 113 with finger to make the holding part 133b rotate, so that the locking component 128 resists to the push force of the plate spring 129 and moves to the direction which is opposite from the pushing direction and divorces from the locking part 107a. Thereby it can provide a structure-simple and cheap locking device.

The second locking mechanism is used for preventing the sliding pieces from being separated from the inner wall of the outer pipe. According to the intra-pipe bi-directional automatic locking device, the first locking mechanism and the second locking mechanism are arranged, so that the outer pipe and the inner pipe can be locked bi-directionally, on the one hand, connection between the inner pipe and the outer pipe is more steady, and on the other hand, the inner pipe and the outer pipe can be adjusted more conveniently in the telescopic length direction.

The utility model discloses an electrical connector for Christmas lamp trees which comprises an upper and a lower connecting base, first columnar electrodes and elastic devices are arranged in the upper connecting base, second arc-shaped electrodes are arranged in the lower connecting base, and the elastic devices cause the first electrodes to tightly abut against the second electrodes. The first columnar electrodes and the second arc-shaped electrodes form a point-to-surface contact, so that the reliability of electrical connection is increased greatly, allowing a Christmas lamp tree to be universal to high and low voltages. Moreover, sufficient contact between upper and lower layers and natural effect of the Christmas lamp tree can still be ensured even if the Christmas lamp tree is subjected to an external force, and multiple sets of first and second electrodes are electrically connected in one-to-one correspondence, leading to diversified functions of the Christmas lamp tree.

The invention relates to a seat footrest structure and a seat, and the footrest structure comprises: a supporting shaft which is provided with a first locking position and a second locking position along the circumferential direction; a footrest that comprises a root end and a free end which are oppositely arranged, wherein a containing cavity for containing the supporting shaft is formed in the root end, and the footrest can rotate relative to the supporting shaft; a movable locking piece that is arranged in the containing cavity of the footrest; the movable locking piece moves in the radialdirection of the supporting shaft, and when the footrest rotates to the position where the movable locking piece is connected with the first locking position and the second locking position, the footrest and the supporting shaft are kept relatively fixed, and the footrest is in a locked state; when the movable locking piece is separated from the first locking position and the second locking position, the footrest is in an unlocked state and rotates around the supporting shaft; the invention discloses the seat. The footrest can be folded below the seat part. Compared with the prior art, the seat footrest structure has the advantages of being compact and simple in structure, convenient to operate, small in occupied space, more convenient to modulate, wider in application range and concise and attractive in appearance.

A battery pack locking apparatus for a portable terminal includes at least one locking groove formed on the battery pack and at least one locking protrusion which is positioned on the terminal in such a manner that it can linearly reciprocate and which is adapted to be engaged with the locking groove while the battery pack is mounted on the terminal, wherein the battery pack is adapted to be released from the terminal as the locking protrusion linearly reciprocate in the locking groove while being engaged with the locking groove. The battery pack locking apparatus is convenient to use because the battery pack, which is held in the mounting groove, is unlocked by simply operating the locking button and is simultaneously separated from the mounting groove.

The invention discloses an automobile tire maintenance jack, which comprises a base, a vertical fixing column is fixedly connected to the base, and a vertical lifting column is movably arranged in the vertical fixing column; the top of the lifting column is fixedly connected with a horizontal head; The vertical lifting column goes up and down; the structure of the invention is simple, and the structure of the hand-operated hydraulic jack with complex structure and high cost is eliminated. When the jack needs to be locked and the clutch is engaged, the rotation direction of the brake shaft and the stop gear When a conflict occurs, the transmission chain of the transmission system of the entire device is locked, so that the anti-rotation gear stops the active rotation of the active outer ring gear; at this time, a stable locking state is realized; the safety performance is high.

The invention belongs to the field of Christmas light trees and particularly relates to an electric connection device for a Christmas light tree, which comprises an upper connection seat and a lower connection seat, wherein the upper connection seat is internally provided with column-shaped first electrodes; the lower connection seat is internally provided with arc-shaped second electrodes contacted with the first electrodes; and the upper connection seat is also internally provided with an elastic device for providing an elastic force to enable the first electrodes to abut against the second electrodes. As point and surface contact is formed by the column-shaped first electrodes and the arc-shaped second electrodes, the electric connection reliability is greatly improved, and general use of the Christmas light tree in high and low voltage can be realized; under effects of an external force to the Christmas light tree, full contact of the upper layer and the lower layer is not influenced, and the natural effects of the Christmas light tree are not influenced; and due to corresponding electric connection between multiple groups of first electrodes and second electrodes, diversity of functions of the Christmas light tree is realized.

The invention discloses an adjustable baby carriage frame.
